  1. Environmental assessment. Energy efficiency standards for consumer products

    Energy Technology Data Exchange (ETDEWEB)

    McSwain, Berah

    1980-06-01

    The Energy Policy and Conservation Act of 1975 requires DOE to prescribe energy efficiency standards for 13 consumer products. The Consumer Products Efficiency Standards (CPES) program covers: refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners (cooling and heat pumps), furnaces, dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers. This Environmental Assessment evaluates the potential environmental and socioeconomic impacts expected as a result of setting efficiency standards for all of the consumer products covered by the CPES program. DOE has proposed standards for eight of the products covered by the Program in a Notice of Proposed Rulemaking (NOPR). DOE expects to propose standards for home heating equipment, central air conditioners (heat pumps only), dishwashers, television sets, clothes washers, and humidifiers and dehumidifiers in 1981. No significant adverse environmental or socioeconomic impacts have been found to result from instituting the CPES.

  2. Environmental assessment for the Consumer Products Efficiency Standards program

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-23

    The Energy Policy and Conservation Act of 1975 as amended by the National Energy Conservation Policy Act of 1978, requires the DOE to prescribe energy efficiency standards for thirteen consumer products. The Consumer Products Efficiency Standards (CPES) program covers the following products: refrigerators and refrigerator-freezers; freezers;clothes dryers;water heaters; room air conditioners; home heating equipment (not including furnaces); kitchen ranges and ovens; central air conditioners (cooling and heat pumps); furnaces; dishwashers; television sets; clothes washers; and humidifiers and dehumidifiers. DOE is proposing two sets of standards for all thirteen consumer products: intermediate standards to become effective in 1981 for the first nine products and in 1982 for the second four products, and final standards to become effective in 1986 and 1987, respectively. The final standards are more restrictive than the intermediate standards and will provide manufacturers with the maximum time permitted under the Act to plan and develop extensive new lines of efficient consumer products. The final standards proposed by DOE require the maximum improvements in efficiency which are technologically feasible and economically justified, as required by Section 325(c) of EPCA. The thirteen consumer products account for approximately 90% of all the energy consumed in the nation's residences, or more than 20% of the nation's energy needs. Increases in the energy efficiency of these consumer products can help to narrow the gap between the nation's increasing demand for energy and decreasing supplies of domestic oil and natural gas. Improvements in the efficiency of consumer products can thus help to solve the nation's energy crisis.

  4. Assessment of the Impacts of Standards and Labeling Programs inMexico (four products).

    Energy Technology Data Exchange (ETDEWEB)

    Sanchez, Itha; Pulido, Henry; McNeil, Michael A.; Turiel, Isaac; della Cava, Mirka

    2007-06-12

    This study analyzes impacts from energy efficiency standards and labeling in Mexico from 1994 through 2005 for four major products: household refrigerators, room air conditioners, three-phase (squirrel cage) induction motors, and clothes washers. It is a retrospective analysis, seeking to assess verified impacts on product efficiency in the Mexican market in the first ten years after standards were implemented. Such an analysis allows the Mexican government to compare actual to originally forecast program benefits. In addition, it provides an extremely valuable benchmark for other countries considering standards, and to the energy policy community as a whole. The methodology for evaluation begins with historical test data taken for a large number of models of each product type between 1994 and 2005. The pre-standard efficiency of models in 1994 is taken as a baseline throughout the analysis. Model efficiency data were provided by an independent certification laboratory (ANCE), which tested products as part of the certification and enforcement mechanism defined by the standards program. Using this data, together with economic and market data provided by both government and private sector sources, the analysis considers several types of national level program impacts. These include: Energy savings; Environmental (emissions) impacts, and Net financial impacts to consumers, manufacturers and utilities. Energy savings impacts are calculated using the same methodology as the original projections, allowing a comparison. Other impacts are calculated using a robust and sophisticated methodology developed by the Instituto de Investigaciones Electricas (IIE) and Lawrence Berkeley National Laboratory (LBNL), in a collaboration supported by the Collaborative Labeling and Standards Program (CLASP).

  6. Exposure method development for risk assessment to cosmetic products using a standard composition.

    Science.gov (United States)

    Chevillotte, G; Ficheux, A S; Morisset, T; Roudot, A C

    2014-06-01

    In a risk assessment of cosmetic products, it is necessary to know both qualitative and quantitative compositions. Currently, European Regulation No. 1223/2009 requires the industries to provide ingredient lists for finished cosmetic products but not their concentrations. Ingredient concentrations are available in few bibliographic references but in an incomplete and approximate way. In this study, we propose a method to qualitatively and quantitatively estimate the composition of a cosmetic product. This method has the advantages of being applicable to all cosmetic products and supplying concentration data for all ingredients. The results obtained seem quite fair compared to literature data. Applied to nail polish as an example, this method can be used to assess exposure per ingredient according to the Monte Carlo probabilistic method. It should be promising to assess the consumer risk to cosmetic product compositions.

  7. Product evaluation and standardization.

    Science.gov (United States)

    Fry, M

    1986-01-01

    Although it was cumbersome at the time of implementation, the process began to operate effectively once hospital personnel overcame their initial concern over a potential "paperwork jungle" and realized that the paperwork is easy to control. When implementing such a system, it is vital that all personnel make a commitment to the process. Although it can be time-consuming and demanding in that employees must attend meetings, write standards, conduct and coordinate evaluations, the benefits are paid back many times over, both in dollars and staff satisfaction. A major plus of our system is our requirement that the user justify why a product is needed. That need is explained in the content of a product standard. The demerit rating system, while not a precise mathematical science, does indicate the relative importance of each criterion. The final result is a standard product, a standard process and a standard decision, against which both product and process performance can be measured. This measurement is a level of professionalism achieved by the actions of a motivated staff, working in cooperation toward a single goal.

  8. Scientific and regulatory standards for assessing product performance using the similarity factor, f2.

    Science.gov (United States)

    Stevens, Ruth E; Gray, Vivian; Dorantes, Angelica; Gold, Lynn; Pham, Loan

    2015-03-01

    The similarity factor, f2, measures the sameness of dissolution profiles. The following commentary is an overview of discussions and presentations from a group of industry and US regulatory experts that have integrated the science and regulatory research and practice for assessing product performance, particularly for modified-release (MR) dosage forms, using f2. For a drug development sponsor or applicant with an orally complex dosage formulation, it is critical to understand dissolution methods and the similarity factor and how and/or when to apply it in their NDA, ANDA, or PMA submission. As part of any regulatory submission, it is critical to justify that the product performance has not been impacted by any change in the manufacturing process and/or the delayed and/or prolonged drug release characteristics compared to a similar conventional or another orally complex dosage form. The purposes of this document are (1) to provide a description of appropriate dissolution methods, how is the f2 calculated and how it can be used to justify product performance similarity, or not; (2) to provide an overview of alternative methods available for dissolution profile comparisons, and (3) to illustrate how applying these concepts in a focused way supports approval of submissions and regulatory dossiers and aligns them with on-going science and regulatory initiatives. A case study will be used as an example to demonstrate how dissolution testing and the f2 calculation results can impact regulatory outcomes from an NDA (505(b)(1)), NDA (505(b)(2)), ANDA (505(j)), supplemental NDAs/ANDAs, or PMA perspective.

  9. Assessment of a Standardized ROS Production Profile in Humans by Electron Paramagnetic Resonance

    2012-01-01

    Full Text Available Despite the growing interest in the role of reactive oxygen species (ROS in health and disease, reliable quantitative noninvasive methods for the assessment of oxidative stress in humans are still lacking. EPR technique, coupled to a specific spin probe (CMH: 1-hydroxy-3-methoxycarbonyl-2,2,5,5-tetramethylpyrrolidine is here presented as the method of choice to gain a direct measurement of ROS in biological fluids and tissues. The study aimed at demonstrating that, differently from currently available “a posteriori” assays of ROS-induced damage by means of biomolecules (e.g., proteins and lipids spin-trapping EPR provides direct evidence of the “instantaneous” presence of radical species in the sample and, as signal areas are proportional to the number of excited electron spins, lead to absolute concentration levels. Using a recently developed bench top continuous wave system (e-scan EPR scanner, Bruker dealing with very low ROS concentration levels in small (50 μL samples, we successfully monitored rapid ROS production changes in peripheral blood of athletes after controlled exercise and sedentary subjects after antioxidant supplementation. The correlation between EPR results and data obtained by various enzymatic assays (e.g., protein carbonyls and thiobarbituric acid reactive substances was determined too. Synthetically, our method allows reliable, quick, noninvasive quantitative determination of ROS in human peripheral blood.

  11. SANITARY-EPIDEMIOLOGICAL ASSESSMENT OF THE PRODUCTS FOR WHICH STANDARDS REGULATING CONTENT OF NATURAL RADIONUCLIDES ARE NOT STATED

    Directory of Open Access Journals (Sweden)

    I. P. Stamat

    2015-01-01

    Full Text Available In the recent years, products that are produced using natural minerals with a high content of natural radionuclides have become widely used by households. The natural background radiation level can vary by tens and hundred times even for similar products, while areas of their application can differ from jewelry to medicine. However, normative documents (guidelines on the content of natural radionuclides in such products have not been yet created. To ensure radiation safety in the use of these products, the dose limit is set: the effective annual dose due to direct use of these products must not exceed 0.1 mSv. This article discusses issues related to the application of the dedicated sections of the documents OSPORB-99/2010 and SanPiN 2.6.1.2800-10 during sanitary-epidemiological assessment of the products, for which regulations on the content of natural radionuclide’s are not created. Possible scenarios of humanexposure when using these products with the primary purpose are considered. Based on the limit of 0.1 mSv annual effective dose, the criteria for a rapid compliance assessment of the radiological characteristics of the individual groups of these products are proposed.

    Hatsukami, Dorothy K; Stepanov, Irina; Severson, Herb; Jensen, Joni A; Lindgren, Bruce R; Horn, Kimberly; Khariwala, Samir S; Martin, Julia; Carmella, Steven G; Murphy, Sharon E; Hecht, Stephen S

    2015-01-01

    Smokeless tobacco products sold in the United States vary significantly in yields of nicotine and tobacco-specific nitrosamines (TSNA). With the passage of the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration now has the authority to establish product standards. However, limited data exist determining the relative roles of pattern of smokeless tobacco use versus constituent levels in the smokeless tobacco product in exposure of users to carcinogens. In this study, smokeless tobacco users of brands varying in nicotine and TSNA content were recruited from three different regions in the U.S. Participants underwent two assessment sessions. During these sessions, demographic and smokeless tobacco use history information along with urine samples to assess biomarkers of exposure and effect were collected. During the time between data collection, smokeless tobacco users recorded the amount and duration of smokeless tobacco use on a daily basis using their diary cards. Results showed that independent of pattern of smokeless tobacco use and nicotine yields, levels of TSNA in smokeless tobacco products played a significant role in carcinogen exposure levels. Product standards for reducing levels of TSNA in smokeless tobacco products are necessary to decrease exposure to these toxicants and potentially to reduce risk for cancer.

    2013-04-01

    Cellulite is a very common skin alteration with a complex pathogenesis; different degrees of severity of cellulite can be observed in most part of people after puberty, and numerous cosmetic or more invasive treatments have been proposed, with variable efficacy. Since reproducible methods of evaluation of the effectiveness of cellulite treatments are lacking, the purpose of our group was to define and set general testing principles for evaluating the efficacy of slimming products and treatments/remodeling methods for cellulite, to achieve a delineation of reliable and reproducible research steps following a well-designed and scientifically valid methodology. After a careful review of literature and textbooks and according to personal experience, we defined assessment protocols based on clinical and instrumental tools. In order to make studies reliable, reproducible and safe, a protocol standardization is needed. The sponsor is responsible for assuring quality and information concerning the product under investigation; moreover, investigators should be experienced on cellulite evaluation and treatment, and, finally, the duration and modalities of application of the product should be specified. A treated VS non treated area comparison can be performed, to evaluate the severity of cellulite and the clinical outcomes of the treatment. Besides clinical evaluation, instrumental methods should always be implemented to provide objective data for treatment outcome.

  2. Results from Screening Polyurethane Foam Based Consumer Products for Flame Retardant Chemicals: Assessing Impacts on the Change in the Furniture Flammability Standards

    Science.gov (United States)

    2016-01-01

    Flame retardant (FR) chemicals have often been added to polyurethane foam to meet required state and federal flammability standards. However, some FRs (e.g., PBDEs and TDCIPP) are associated with health hazards and are now restricted from use in some regions. In addition, California’s residential furniture flammability standard (TB-117) has undergone significant amendments over the past few years, and TDCIPP has been added to California’s Proposition 65 list. These events have likely led to shifts in the types of FRs used, and the products to which they are applied. To provide more information on the use of FRs in products containing polyurethane foam (PUF), we established a screening service for the general public. Participants residing in the US were allowed to submit up to 5 samples from their household for analysis, free of charge, and supplied information on the product category, labeling, and year and state of purchase. Between February 2014 and June 2016, we received 1141 PUF samples for analysis from various products including sofas, chairs, mattresses, car seats and pillows. Of these samples tested, 52% contained a FR at levels greater than 1% by weight. Tris(1,3-dichloroisopropyl)phosphate (TDCIPP) was the most common FR detected in PUF samples, and was the most common FR detected in all product categories. Analysis of the data by purchasing date suggests that the use of TDCIPP decreased in recent years, paralleled with an increase in the use of TCIPP and a nonhalogenated aryl phosphate mixture we call “TBPP.” In addition, we observed significant decreases in FR applications in furniture products and child car seats, suggesting the use of additive FRs in PUF may be declining, perhaps as a reflection of recent changes to TB-117 and Proposition 65. More studies are needed to determine how these changes in FR use relate to changes in exposure among the general population. PMID:27552529

  6. Organic fish production and the standards

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available Fish that are produced under natural conditions in accordance with the principles of organic agriculture without any use of preservative additives and without any genetic modifications, that are fed feed produced from natural raw materials, that are certified by a qualified institution are defined as “organic fish”. Organic fish production is a production model that emphasizes human health without using pesticides, chemical and genetically modified products, as well as ensuring animal welfare by decreasing the stocking density. This alternative model is used in many developed and developing countries in the world and the demand for this product has been the cause of increase in production amount and species variety in the market, although the model comprises 0.01% of the world aquaculture production. However, organic aquaculture production has not been developed as rapidly as organic agriculture. One of the most important reasons of this is the absence of international standards issued for organic aquaculture production. In this paper, the production principles of a number of authorized institutions certifying organic aquaculture are comparatively discussed.

  9. Sharing data for production scheduling using the ISA-95 standard

    Directory of Open Access Journals (Sweden)

    Iiro eHarjunkoski

    2014-10-01

    Full Text Available In the development and deployment of production scheduling solutions one major challenge is to establish efficient information sharing with industrial production management systems. Information comprising production orders to be scheduled, processing plant structure, product recipes, available equipment and other resources are necessary for producing a realistic short-term production plan. Currently, a widely-accepted standard for information sharing is missing. This often leads to the implementation of costly custom-tailored interfaces, or in the worst case the scheduling solution will be abandoned. Additionally, it becomes difficult to easily compare different methods on various problem instances, which complicates the re-use of existing scheduling solutions. In order to overcome these hurdles, a platform-independent and holistic approach is needed. Nevertheless, it is difficult for any new solution to gain wide acceptance within industry as new standards are often refused by companies already using a different established interface. From an acceptance point of view, the ISA-95 standard could act as a neutral data-exchange platform. In this paper, we assess if this already widespread standard is simple, yet powerful enough to act as the desired holistic data-exchange for scheduling solutions.

(Kinderklinik Schwabing, Muenchen (Germany))

    1994-04-01

    777 cerebral MRI examinations of children aged 3 days to 14 years were staged for myelination to establish an age standardization. Staging was performed using a system proposed in a previous paper, separately ranking 10 different regions of the brain. Interpretation of the results led to the identification of foue clinical diagnoses that are frequently associated with delays in myelination: West syndrome, cerebral palsy, developmental retardation, and congenital anomalies. In addition, it was found that assessment of myelination in children with head injuries was not practical as alterations in MRI signal can simulate earlier stages of myelination. Age limits were therefore calculated from the case material after excluding all children with these conditions. When simplifications of the definition of the stages are applied, these age limits for the various stages of myelination of each of the 10 regions of the brain make the staging system applicable for routine assessment of myelination.

    2005-01-01

    The authenticity of dairy products has become a focal point, attracting the attention of scientists, producers, consumers, and policymakers. Among many others, some of the practices not allowed in milk and milk products are the substitution of part of the fat or proteins, admixtures of milk of different species, additions of low-cost dairy products (mainly whey derivatives), or mislabeling of products protected by denomination of origin. A range of analytical methods to detect frauds have been developed, modified, and continually reassessed to be one step ahead of manufacturers who pursue these illegal activities. Traditional procedures to assess the authenticity of dairy products include chromatographic, electrophoretic, and immunoenzymatic methods. New approaches such as capillary electrophoresis, polymerase chain reaction, and isotope ratio mass spectrometry have also emerged alongside the latest developments in the former procedures. This work intends to provide an updated and extensive overview since 1991 on the principal applications of all these techniques together with their advantages and disadvantages for detecting the authenticity of dairy products. The scope and limits of different tools are also discussed.

    Some aspects of research development and production of quantum frequency standards, carried out in QUARTZ Research and Production Association (RPA), Gorky, U.S.S.R., were investigated for the last 25 to 30 years. During this period a number of rubidium and hydrogen frequency standards, based on the active maser, were developed and put into production. The first industrial model of a passive hydrogen maser was designed in the last years. Besides frequency standards for a wide application range, RPA QUARTZ investigates metrological frequency standards--cesium standards with cavity length 1.9 m and hydrogen masers with a flexible storage bulb.

    2007-10-01

    Full Text Available Indexing is one of the most important methods of content representation where by assigning descriptors to the documents, their subject content are made known. Since index and indexing are remarkably significant in information retrieval, its quality and evaluation and provision of criteria and standards had always been the mainstay of researchers in this field. Given the fact that Indexing is a complex process, offering definitions, principles and methods could be step towards optimal use of the information. The present study, while offering a capsule definition of index, will investigate the indexing evaluation criteria and would follow it up with a definition of indexing. Finally a number of standards in the field of indexing are presented and would make its conclusions.

  6. Assessing the Genetics Content in the Next Generation Science Standards.

    Science.gov (United States)

    Lontok, Katherine S; Zhang, Hubert; Dougherty, Michael J

    2015-01-01

    Science standards have a long history in the United States and currently form the backbone of efforts to improve primary and secondary education in science, technology, engineering, and math (STEM). Although there has been much political controversy over the influence of standards on teacher autonomy and student performance, little light has been shed on how well standards cover science content. We assessed the coverage of genetics content in the Next Generation Science Standards (NGSS) using a consensus list of American Society of Human Genetics (ASHG) core concepts. We also compared the NGSS against state science standards. Our goals were to assess the potential of the new standards to support genetic literacy and to determine if they improve the coverage of genetics concepts relative to state standards. We found that expert reviewers cannot identify ASHG core concepts within the new standards with high reliability, suggesting that the scope of content addressed by the standards may be inconsistently interpreted. Given results that indicate that the disciplinary core ideas (DCIs) included in the NGSS documents produced by Achieve, Inc. clarify the content covered by the standards statements themselves, we recommend that the NGSS standards statements always be viewed alongside their supporting disciplinary core ideas. In addition, gaps exist in the coverage of essential genetics concepts, most worryingly concepts dealing with patterns of inheritance, both Mendelian and complex. Finally, state standards vary widely in their coverage of genetics concepts when compared with the NGSS. On average, however, the NGSS support genetic literacy better than extant state standards.

  8. Performance Standards': Utility for Different Uses of Assessments

    Directory of Open Access Journals (Sweden)

    Robert L. Linn

    2003-09-01

    Full Text Available Performance standards are arguably one of the most controversial topics in educational measurement. There are uses of assessments such as licensure and certification where performance standards are essential. There are many other uses, however, where performance standards have been mandated or become the preferred method of reporting assessment results where the standards are not essential to the use. Distinctions between essential and nonessential uses of performance standards are discussed. It is argued that the insistence on reporting in terms of performance standards in situations where they are not essential has been more harmful than helpful. Variability in the definitions of proficient academic achievement by states for purposes of the No Child Left Behind Act of 2001 is discussed and it is argued that the variability is so great that characterizing achievement is meaningless. Illustrations of the great uncertainty in standards are provided.

The data measured with the Thermal And Near-infrared Sensor for carbon Observation Fourier Transform Spectrometer (TANSO-FTS) and the Cloud and Aerosol Imager (TANSO-CAI) are processed into several types of data products. Column abundances of CO2 and CH4 (TANSO-FTS SWIR L2 data product) are retrieved from the FTS L1B spectral data. Validation of the FTS Level 2 data product is critical since the data is used for generating the FTS Level 3 (global distributions of column-averaged mixing ratio data of XCO2 and XCH4) and the FTS Level 4 (regional CO2 fluxes and three dimensional distribution of CO2 calculated from the estimated fluxes) products. The reference data to be used for validating abundances are required to have uncertainties of less than 1.0 % (0.3 % or 1 ppm is desirable) for CO2 and 2.0 % for CH4. Ground

    Products and their components underlie constant devaluation by their usage which sooner or later leads to a failure. As manufacturers of complex technical products are confronted with increasing demands regarding product availability and reliability, the assessment of the product's condition is desirable. Existing microelectronic technology enables a constant supervision of standard components in their usage to initiate timely adaptation processes like maintenance and repair. The Life Cycle Unit is presented as a modular microelectronic system for product supervision and assessment. Life Cycle Units have been prototypically implemented in various application examples using SMD technology and microsystem technology. (orig.)

    Chow, Shein-Chung; Liu, Jen-Pei

    2010-01-01

    Biological products or medicines are therapeutic agents that are produced using a living system or organism. Access to these life-saving biological products is limited because of their expensive costs. Patents on the early biological products will soon expire in the next few years. This allows other biopharmaceutical/biotech companies to manufacture the generic versions of the biological products, which are referred to as follow-on biological products by the U.S. Food and Drug Administration (FDA) or as biosimilar medicinal products by the European Medicine Agency (EMEA) of the European Union (EU). Competition of cost-effective follow-on biological products with equivalent efficacy and safety can cut down the costs and hence increase patients' access to the much-needed biological pharmaceuticals. Unlike for the conventional pharmaceuticals of small molecules, the complexity and heterogeneity of the molecular structure, complicated manufacturing process, different analytical methods, and possibility of severe immunogenicity reactions make evaluation of equivalence (similarity) between the biosimilar products and their corresponding innovator product a great challenge for both the scientific community and regulatory agencies. In this paper, we provide an overview of the current regulatory requirements for approval of biosimilar products. A review of current criteria for evaluation of bioequivalence for the traditional chemical generic products is provided. A detailed description of the differences between the biosimilar and chemical generic products is given with respect to size and structure, immunogenicity, product quality attributed, and manufacturing processes. In addition, statistical considerations including design criteria, fundamental biosimilar assumptions, and statistical methods are proposed. The possibility of using genomic data in evaluation of biosimilar products is also explored.

    2000-01-01

    The need for an agreed upon set of standards for assessing individuals with XLMR was made quite evident this past year at the Fragile X and XLMR Workshop in Strasbourg. Several affected individuals from different families may have been incorrectly diagnosed as MR. Many factors can have a negative affect on IQ testing. As a result, evaluating individuals with cognitive deficits can be problematic. To be effective, psychological assessments must produce uniform results that are consistent with the definition of MR. Therefore, to foster international research in XLMR. I propose a two-stage standardized protocol. To determine which tests may be suitable. I review an assortment of instruments for psychological assessment at each stage, noting their strengths and weaknesses. Afterward, I present a set of standardized protocols based on age and language ability.

    This background report describes the technical basis for the newly proposed American Nuclear Society (ANS) 5.4 standard, Methods for Calculating the Fractional Release of Volatile Fission Products from Oxide Fuels. The proposed ANS 5.4 standard provides a methodology for determining the radioactive fission product releases from the fuel for use in assessing radiological consequences of postulated accidents that do not involve abrupt power transients. When coupled with isotopic yields, this method establishes the 'gap activity,' which is the inventory of volatile fission products that are released from the fuel rod if the cladding are breached.

    For the sake of objectivity of the interpretation in life cycle assessment (LCA), the concept and the design proposal of Standard Flow were put forward. Standard Flow was defined as the collection of related environmental load parameters that represent the specific development degree of certain industrial process(es) by the function unit. A novel methodological approach called the Standard Flow Comparing, was developed for LCA. The indicator for potential of process improvement and its weighting factor were derived. To a certain degree the problem of the identification and selection of process development objects in LCA was solved. The concept of Standard Flow and the method of Standard Flow Comparing are introduced, formulized and analyzed.

    2013-11-01

    The 1st International Standard for Diphtheria Antitoxin Human (coded 10/262) was established by the World Health Organization Expert Committee on Biological Standardization in 2012. This paper describes the production, characterization and calibration of the new standard which is intended for use in the standardization of assays used to measure diphtheria antibody responses in human serum. The new standard was calibrated in terms of the International Standard for Diphtheria Antitoxin Equine in an international collaborative study. A total of 8 participants from 8 different countries performed in vivo and/or in vitro toxin neutralization tests and returned data that was used to assign units to the proposed new standard. The new standard has a diphtheria antitoxin potency of 2 IU/ampoule and is predicted to be stable. A follow up study was performed to assess commutability of the new standard. The follow up study was an existing external quality assessment, modified to include the new standard. Results obtained suggest that the new standard is commutable, showing comparable behaviour to native human serum samples in the majority of the assays compared, and is therefore suitable for use as a reference preparation in assays used to measure the level of anti-diphtheria antibodies in human serum.

  3. Standards of Ombudsman Assessment: A New Normative Concept?

    Directory of Open Access Journals (Sweden)

    Milan Remac

    2013-07-01

    Full Text Available Today, an ombudsman is a traditional component of democratic legal systems. Generally, reports of the ombudsman are not legally binding. Due to this fact, the ombudsman can rely only on his own persuasiveness, on his acceptance by individuals and state institutions, on the understanding of the administration and on the accessibility and transparency of rules that underpin his reports. During investigations, ombudsmen assess whether the administration has acted in accordance with certain legal or extra-legal standards. Depending on the legal system, ombudsmen can investigate whether there is an instance of maladministration in the activities of administrative bodies, whether the administration has acted ‘properly’, whether it has acted in accordance with the law, whether administrative actions have breached the human rights of complainants or whether the actions of the administration were in accordance with anti-corruption rules etc. Regardless of the legislative standard of an ombudsman’s control, the ombudsman should consider and assess the situation described in complaints against certain criteria or against certain normative standards. A distinct set of standards which ombudsmen use during their investigation, or at least a clear statement of their assessment criteria, can increase the transparency of their procedures and the persuasiveness of their reports. Are the normative standards used by different ombudsmen the same? Do they possibly create a new normative concept? And can it possibly lead to a higher acceptance of their reports by the administration?

    2014-01-01

    The interdisciplinary team (IDT) approach is critical in the care of elderly adults. Performance-based tools to assess IDT skills have not been well validated. A novel assessment tool, the standardized patient (SP) and standardized interdisciplinary team meeting (SIDTM), consisting of two stations, was developed. First, trainees evaluate a SP hospitalized after a fall. Second, trainees play the role of the physician in a standardized IDT meeting with a standardized registered nurse (SRN) and standardized medical social worker (SMSW) for discharge planning. The SP-SIDTM was administered to 52 fourth-year medical students (MS4s) and six geriatric medicine fellows (GMFs) in 2011/12. The SP, SRN, and SMSW scored trainee performance on dichotomous checklists of clinical tasks and Likert scales of communication skills, which were compared according to level of training using t-tests. Trainees rated the SP-SIDTM experience as moderately difficult, length of time about right, and believability moderate to high. Reliability was high for both cases (Cronbach α = 0.73-0.87). Interobserver correlation between SRN and SMSW checklist scores (correlation coefficient (r) = 0.82, P < .001) and total scores (r = 0.69, P < .001) were high. The overall score on the SP-SIDTM case was significantly higher for GMF (75) than for MS4 (65, P = .002). These observations support the validity of this novel assessment tool.

  10. Accelerating the Adoption of Second-Tier Reach Standards forApplicable Appliance Products in China

    Energy Technology Data Exchange (ETDEWEB)

    Lin, Jiang; Fridley, David

    2007-03-01

    The minimum energy efficiency standards program for household appliances in China was initiated in 1989. Since 1996, CLASP and its implementing partner, LBNL, have assisted China in developing 11 minimum energy performance standards (MEPS) for 9 products and endorsement labels for 11 products including: refrigerators; air conditioners; clothes washers; televisions; printers; computers; monitors; fax machines; copiers; DVD/VCD players; external power supplies; and set-top boxes (under development). Before 2003, China's traditional approach to standards development involved small increases in efficiency requirements for implementation within 6 months of a standard's approval. Since 2003, China has adopted a new approach in setting MEPS. This new approach involves the development of two tiers of standards--one for initial implementation and a second tier at a more aggressive level of energy efficiency for implementation three to five years later. The second-tier standard is also referred to as a 'reach standard'. Reach standards have now been developed in China for: color TVs; refrigerators; air conditioners; and external power supplies. This report is presented in five sections. After the introduction in Section 1, Section 2 analyzes the distribution of the efficiency of refrigerators and air-conditioners in China based on data collected by the China Energy Label Center for the mandatory energy information label program. The results provide an assessment of the adoption of reach standards for these two products. Section 3 summarizes on-going collaborations with Shanghai related to early local adoption of reach standards, and presents both the impact and an analysis of barriers to the local adoption of reach standard for air-conditioners. Section 4 offers suggestions for local governments on how to move forward in adopting reach standards in their localities and concludes with a summary of the results and a plan for developing local capacity in

    Full Text Available Investigations conducted within project "Techonological and protective characteristics of autochthonous strains of lactic acid bacteria isolated from traditional fermented sausages and possibilities for their implementation in the meat industry" (Project Number: 20127, financed on behalf of the Ministry for Science and Technology of the Republic of Serbia, have provided an answer on the characteristics of the quality of the used raw materials for the production of Sremska sausage - one of the most well-known Serbian traditionally fermented sausages (choice of meat, fatty tissue, additives and spices, and data have been registered in connection with the procedures of their processing, microclimatic conditions have been established (temperature, relative humidity, and air circulation during the entire process of production and fermentation, as well as the presence and types of microorganisms, primarily lactic acid bacteria (BMK, the carrier of lactic fermentation. The most important characteristics of the filling have been established, the smoking regimen, the regimens of fermentation, maturing, drying, as well as the parameters for quality and safety of the finished product. At the same time, the standard working procedure has been determined for the preparation of the meat, fatty tissue, the forming and inserting of the filling into the wrappers, as well as the characteristics of the finished products. The given standard working procedure should serve as a guideline for the meat industry in the production process of this traditional fermented sausage.

    Authors Robert E. Sehenter, Garry Brown and Charles S. Holden argue that a Standard for 'Medical Isotope Production' is needed. Medical isotopes are becoming major components of application for the diagnosis and treatment of all the major diseases including all forms of cancer, heart disease, arthritis, Alzheimer's, among others. Current nuclear data to perform calculations is incomplete, dated or imprecise or otherwise flawed for many isotopes that could have significant applications in medicine. Improved data files will assist computational analyses to design means and methods for improved isotope production techniques in the fission reactor systems. Initial focus of the Standard is expected to be on neutron cross section and branching data for both fast and thermal reactor systems. Evaluated and reviewed tables giving thermal capture cross sections and resonance integrals for the major target and product medical isotopes would be the expected 'first start' for the 'Standard Working Group'.

    The purposes of this paper are (1) to identify key states' activities and plans related to setting cleanup standards using the ecological risk assessment process, and (2) to discuss the impacts these actions may have on the US Department of Energy's (DOE's) environmental restoration program. This report is prepared as part of a larger task, the purpose of which is to identify and assess state regulatory trends and legal developments that may impact DOE's environmental restoration program. Results of this task are intended to provide DOE with advance notice of potentially significant regulatory developments so as to enhance DOE's ability to influence these developments and to incorporate possible regulatory and policy changes into its planning process.

  16. Student's Video Production as Formative Assessment

    2013-01-01

    Learning assessments are subject of discussions that envolve theoretical and practical approaches. To measure learning in physics by high school students, either qualitatively or quantitatively, is a process in which it should be possible to identify not only the concepts and contents students failed to achieve but also the reasons of the failure. We propose that students' video production offers a very effective formative assessment to teachers: as a formative assessment, it produces information that allows the understanding of where and when the learning process succeeded or failed, of identifying, as a subject or as a group, the defficiencies or misunderstandings related to the theme under analysis and their interpretation by students, and it provides also a different kind of assessment, related to some other life skills, like the ability to carry a project to its conclusion and to work cooperatively. In this paper, we describe the use of videos produced by high school students as an assessment resource. T...

    Experimental limits from ATLAS on Standard Model Higgs production in the mass range 110-600 GeV. The solid curve reflects the observed experimental limits for the production of a Higgs of each possible mass value (horizontal axis). The region for which the solid curve dips below the horizontal line at the value of 1 is excluded with a 95% confidence level (CL). The dashed curve shows the expected limit in the absence of the Higgs boson, based on simulations. The green and yellow bands correspond (respectively) to 68%, and 95% confidence level regions from the expected limits. Higgs masses in the narrow range 123-130 GeV are the only masses not excluded at 95% CL

    EFSA’s Panel on Plant Protection Products and their Residues (PPR Panel provides independent scientific advice in the field of risk assessment of plant protection products (PPPs, pesticides. Since its establishment in 2003 under Regulation (EC No 178/2002, it has delivered a series of scientific outputs in support of evaluation of pesticide active substances, establishing scientific principles and guidance documents in the field of pesticide risk assessment and in support of decision making of European Union (EU law makers. Next to a series of scientific opinions evaluating specific adverse effects of PPPs for human health (like for instance carcinogenicity the Panel also delivered scientific opinions on general principles in the field of human health risk assessment (like reference value setting and is, in particular over the last years, very much engaged in development of methodologies to meet new challenges in regulatory risk assessments such as assessment of toxicity of pesticide metabolites and potential cumulative effects of pesticides to human health. Fate, behaviour and transformation of pesticides after their application and consequent release to the environment are a major aspect of pesticide risk assessment. The PPR Panel has achieved major accomplishments by delivering guidance and scientific opinions on degradation in soil, exposure of soil organisms and assessment of environmental risks by use of pesticides in greenhouses or grown under cover. A series of scientific opinions have been delivered also in the field of environmental risk assessment of pesticides. Scientific output covered specific issues arising in the peer review of specific active substances, revision of data requirements, development of risk assessment methodologies and the development of guidance documents. A major milestone of the PPR Panel was the development of the methodological framework for deriving specific protection goals for environmental risk

  1. Pair Production of Beyond the Standard Model Higgs Bosons

    CERN Document Server

    Gröber, Ramona

    2016-01-01

    Higgs pair production is not only sensitive to the trilinear Higgs self-coupling, but it can give access to other anomolous couplings, as e.g. a novel $hht\\bar{t}$ coupling. In Composite Higgs Models, this coupling usually leads to a large increase of the cross section. In such a framework an interesting question is, whether it might be possible to observe new physics for the first time in Higgs pair production. This question will be addressed by taking into account projected sensitivities for Higgs coupling measurements and for direct searches of new vector-like quarks. Higher order corrections to Higgs pair production via gluon fusion are sizeable. It is hence not only important to compute them in the Standard Model (SM) but also in its extensions. Here, the computation of the QCD corrections in the SM with dimension 6 operators as well as the SUSY-QCD corrections to Higgs pair production via gluon fusion in the MSSM are presented.

    2016-12-01

    Regulatory decisions regarding microbiological safety of cosmetics and personal care products are primarily hazard-based, where the presence of a potential pathogen determines decision-making. This contrasts with the Food industry where it is a commonplace to use a risk-based approach for ensuring microbiological safety. A risk-based approach allows consideration of the degree of exposure to assess unacceptable health risks. As there can be a number of advantages in using a risk-based approach to safety, this study explores the Codex Alimentarius (Codex) four-step Microbiological Risk Assessment (MRA) framework frequently used in the Food industry and examines how it can be applied to the safety assessment of personal care products. The hazard identification and hazard characterization steps (one and two) of the Codex MRA framework consider the main microorganisms of concern. These are addressed by reviewing the current industry guidelines for objectionable organisms and analysing reports of contaminated products notified by government agencies over a recent 5-year period, together with examples of reported outbreaks. Data related to estimation of exposure (step three) are discussed, and examples of possible calculations and references are included. The fourth step, performed by the risk assessor (risk characterization), is specific to each assessment and brings together the information from the first three steps to assess the risk. Although there are very few documented uses of the MRA approach for personal care products, this study illustrates that it is a practicable and sound approach for producing products that are safe by design. It can be helpful in the context of designing products and processes going to market and with setting of microbiological specifications. Additionally, it can be applied reactively to facilitate decision-making when contaminated products are released on to the marketplace. Currently, the knowledge available may only allow a

    Full Text Available South Africa’s performance in international benchmark tests is a major cause for concern amongst educators and policymakers, raising questions about the effectiveness of the curriculum reform efforts of the democratic era. The purpose of the study reported in this article was to investigate the degree of alignment between the TIMSS 2003 Grade 8 Mathematics assessment frameworks and the Revised National Curriculum Statements (RNCS assessment standards for Grade 8 Mathematics, later revised to become the Curriculum and Assessment Policy Statements (CAPS. Such an investigation could help to partly shed light on why South African learners do not perform well and point out discrepancies that need to be attended to. The methodology of document analysis was adopted for the study, with the RNCS and the TIMSS 2003 Grade 8 Mathematics frameworks forming the principal documents. Porter’s moderately complex index of alignment was adopted for its simplicity. The computed index of 0.751 for the alignment between the RNCS assessment standards and the TIMSS assessment objectives was found to be significantly statistically low, at the alpha level of 0.05, according to Fulmer’s critical values for 20 cells and 90 or 120 standard points. The study suggests that inadequate attention has been paid to the alignment of the South African mathematics curriculum to the successive TIMSS assessment frameworks in terms of the cognitive level descriptions. The study recommends that participation in TIMSS should rigorously and critically inform ongoing curriculum reform efforts.

    2016-11-01

    The instability in today's market and the ever increasing and emerging demands for mass customized and hybrid products by customers, are driving companies and decision makers to seek for cost effective and time efficient improvements in their product development process. Design concept evaluation which is the end of conceptual design is one of the most critical decision points in product development. It relates to the final success of product development, because poor criteria assessment in design concept evaluation can rarely compensated at the later stages. This has led to real pressure for the adaptation of new developmental architecture and operational parameters to remain competitive in the market. In this paper, a new integrated design concept evaluation based on fuzzy-technique for order preference by similarity to ideal solution (Fuzzy-TOPSIS) is presented, and it also attempts to incorporate sustainability practices in assessing the criteria. Prior to Fuzzy-TOPSIS, a new scale of “Weighting criteria” for survey process is developed to quantify the evaluation criteria. This method will help engineers to improve the effectiveness and objectivity of the sustainable product development. Case example from industry is presented to demonstrate the efficacy of the proposed methodology. The result of the example shows that the new integrated method provides an alternative to existing methods of design concept evaluation.

    2013-09-01

    Disposable absorbent products are widely used in inpatient care settings and in the community to manage adult urinary and fecal incontinence, but few product standards exist to help guide their production or optimal use. Increasing costs and reduced revenues have caused a number of states to evaluate absorbent product use among persons who receive care at home with the assistance of the Medicaid Waiver Program, further increasing concerns about the lack of product performance standards. To address these issues, the National Association For Continence (NAFC) formed a council of experts and key stakeholders with the objective of establishing national, independent quality performance standards for disposable absorbent products provided by states to Waiver Program recipients. The Council consisted of representatives from five purposefully selected states, technical directors from six nonwoven product manufacturers, an officer of the nonwoven manufactures trade association, a delegate from an academic nursing program and professional societies, a family caregiver, and a patient representative. Following a consensus method and guidelines for use, nine specific recommendations were developed, posted for public comment, and further refined. Final recommendations for product performance assessment include: rewet rate (a measure of a product's ability to withstand multiple incontinent episodes between changes), rate of acquisition (a measure of the speed at which urine is drawn away from the skin by a product, product retention capacity (a measure of a product's capacity to hold fluid without rewetting the skin), sizing options, absorbency levels, product safety, closure technology, breathable zones (a measure of the air permeability across a textile-like fabric at a controlled differential pressure), and elasticity. The Council also set values for and recommended four quantifiable parameters, and the testing methodology associated with each, to help consumers and states

    The paper is an update of 2011 Standards for Ultrasound Assessment of Salivary Glands, which were developed by the Polish Ultrasound Society. We have described current ultrasound technical requirements, assessment and measurement techniques as well as guidelines for ultrasound description. We have also discussed an ultrasound image of normal salivary glands as well as the most important pathologies, such as inflammation, sialosis, collagenosis, injuries and proliferative processes, with particular emphasis on lesions indicating high risk of malignancy. In acute bacterial inflammation, the salivary glands appear as hypoechoic, enlarged or normal-sized, with increased parenchymal flow. The echogenicity is significantly increased in viral infections. Degenerative lesions may be seen in chronic inflammations. Hyperechoic deposits with acoustic shadowing can be visualized in lithiasis. Parenchymal fibrosis is a dominant feature of sialosis. Sjögren syndrome produces different pictures of salivary gland parenchymal lesions at different stages of the disease. Pleomorphic adenomas are usually hypoechoic, well-defined and polycyclic in most cases. Warthin tumor usually presents as a hypoechoic, oval-shaped lesion with anechoic cystic spaces. Malignancies are characterized by blurred outlines, irregular shape, usually heterogeneous echogenicity and pathological neovascularization. The accompanying metastatic lesions are another indicator of malignancy, however, final diagnosis should be based on biopsy findings. PMID:27446602

    CO{sub 2} emissions from the home equate to 27 % of UK total emissions. In order for consumers to use less energy, and reduce their environmental impact, the Energy Saving Recommended (ESR) voluntary product labelling scheme for domestic energy saving products was established to direct the consumer to choose better products and make smarter choices. With over 2000 certified products, ESR is present across 5 sectors and covers 24 product categories; 9 sets of standards were reviewed and revised in 2005/6 and a further 13 were delivered in 2006/7. ESR is now implementing existing and developing new standards in consumer electronics - from integrated digital televisions and recorders, to intelligent mains sockets and set-top-boxes, as well as assessing the feasibility of endorsing domestic ICT equipment. The Energy Saving Trust, through its marketing activities, acts as an enabler to make energy saving action simpler, easier and cheaper for the consumer to undertake. Using a variety of communication strategies the trade is engaged through the provision of value added member benefits; a holistic approach is taken with key partners to integrate energy efficiency throughout their businesses. Merchandising support helps product standards to be implemented in the market place; evaluation and research work demonstrates that markets can be changed and shows a 1 in 3 label recognition rate. The credibility and integrity of the label are reinforced through compliance testing, in-store and online label monitoring and legal enforcement, frequent data checks and the integration of ISO best practice standards through the certification system.

    2012-01-01

    Assessing product-image quality is important in the context of online shopping. A high quality image that conveys more information about a product can boost the buyer's confidence and can get more attention. However, the notion of image quality for product-images is not the same as that in other domains. The perception of quality of product-images depends not only on various photographic quality features but also on various high level features such as clarity of the foreground or goodness of the background etc. In this paper, we define a notion of product-image quality based on various such features. We conduct a crowd-sourced experiment to collect user judgments on thousands of eBay's images. We formulate a multi-class classification problem for modeling image quality by classifying images into good, fair and poor quality based on the guided perceptual notions from the judges. We also conduct experiments with regression using average crowd-sourced human judgments as target. We compute a pseudo-regression score with expected average of predicted classes and also compute a score from the regression technique. We design many experiments with various sampling and voting schemes with crowd-sourced data and construct various experimental image quality models. Most of our models have reasonable accuracies (greater or equal to 70%) on test data set. We observe that our computed image quality score has a high (0.66) rank correlation with average votes from the crowd sourced human judgments.

    2011-10-31

    Current interest expressed by industry in HTGR plants, particularly modular plants with power up to about 600 MW(e) per unit, has prompted NRC to task PNNL with assessing the currently available literature related to codes and standards applicable to HTGR plants, the operating history of past and present HTGR plants, and with evaluating the proposed designs of RPV and associated piping for future plants. Considering these topics in the order they are arranged in the text, first the operational histories of five shut-down and two currently operating HTGR plants are reviewed, leading the authors to conclude that while small, simple prototype HTGR plants operated reliably, some of the larger plants, particularly Fort St. Vrain, had poor availability. Safety and radiological performance of these plants has been considerably better than LWR plants. Petroleum processing plants provide some applicable experience with materials similar to those proposed for HTGR piping and vessels. At least one currently operating plant - HTR-10 - has performed and documented a leak before break analysis that appears to be applicable to proposed future US HTGR designs. Current codes and standards cover some HTGR materials, but not all materials are covered to the high temperatures envisioned for HTGR use. Codes and standards, particularly ASME Codes, are under development for proposed future US HTGR designs. A 'roadmap' document has been prepared for ASME Code development; a new subsection to section III of the ASME Code, ASME BPVC III-5, is scheduled to be published in October 2011. The question of terminology for the cross-duct structure between the RPV and power conversion vessel is discussed, considering the differences in regulatory requirements that apply depending on whether this structure is designated as a 'vessel' or as a 'pipe'. We conclude that designing this component as a 'pipe' is the more appropriate choice, but that the ASME BPVC

    Density Functional Theory (DFT) based Equation of State (EOS) construction is a prominent part of Sandia’s capabilities to support engineering sciences. This capability is based on augmenting experimental data with information gained from computational investigations, especially in those parts of the phase space where experimental data is hard, dangerous, or expensive to obtain. A key part of the success of the Sandia approach is the fundamental science work supporting the computational capability. Not only does this work enhance the capability to perform highly accurate calculations but it also provides crucial insight into the limitations of the computational tools, providing high confidence in the results even where results cannot be, or have not yet been, validated by experimental data. This report concerns the key ingredient of projector augmented-wave (PAW) potentials for use in pseudo-potential computational codes. Using the tools discussed in SAND2012-7389 we assess the standard Vienna Ab-initio Simulation Package (VASP) PAWs for Molybdenum.

For this study, we analyzed the current principle of managerial accounting to an entity in the studied area, in order to emphasize the need of organizing and implementing a modern accounting management to control the cost and increase the performance of the entities in this area, starting from the premise that there are sufficient similarities between entities in the field. Research carried out has revealed that currently, the costing is organized in terms of using traditional methods and that it is necessary to organize and implement an accounting management based on the use of modern methods, namely the method of standard costs combined with the method of centres of costs. The major implications of the proposed system for the investigated field consist of determining a relevant cost-oriented management entity, highlighting the shortcomings of traditional methods of cost

In Poland the supervision of safety product has been entrusted to the President of the Office of Competition and Consumer Protection. The agency supporting its activities is the Trade Inspection. Growing popularity of the quality systems conformable with the ISO 9000 standard caused that they have been included in the EU regulations as criteria of assessment of conformability with requirements. The certificate of the quality management system is indispensable for companies for functioning in many market areas. One should remember that quality management system will help the company to supervise unconformable products only when it really functions and is not just on paper. Only then it will function efficiently.

  6. Assessment of MERIS ocean color data products for European seas

    Directory of Open Access Journals (Sweden)

    G. Zibordi

    2013-05-01

    Full Text Available The accuracy of marine data products from the Medium Resolution Imaging Spectrometer (MERIS operated on board the Envisat platform is investigated with the aid of in situ geographically distributed measurements from different European seas. The assessment focuses on standard products from the 2012 data update commonly identified as 3rd Reprocessing. Results indicate atmospherically corrected data affected by a negative bias of several tens percent at the 413 nm center wavelength, significantly decreasing to a few percent at 560 nm and increasing again at 665 nm. Such an underestimate at the blue center wavelengths leads to an average overestimate of the algal-1 MERIS pigment index largely exceeding 100% for the considered European seas. A comparable overestimate is also observed for the algal-2 pigment index independently determined from top-of-atmosphere radiance through the application of neural networks.

    2015-02-01

    ABSTRACT The exploration course on production standard of acupuncture needle by Chengjiang acupuncture school is reviewed in this paper. After new China was established, acupuncture needle standard was unified by Mr. CHENG Dan-an, which guided Suzhou Hua Erfang (predecessor of Suzhou Medical Supplies Factory) to make the quality standards and testing methods of acupuncture needle and improved the production process to make the modern acupuncture needle. Based on this, Suzhou Medical Supplies Factory followed the time development pace, ac tively introduced new technology, carried out technological innovation, and constantly improved the level of production technology, as a result, it gradually developed into one of the world's largest acupuncture needle production suppliers. Meanwhile, after establishing China's first national standard on acupuncture needle (GB 2024-1980), the Suzhou Medical Supplies Factory took the lead to draft "ISO) 17218:2014 the disposable use asepsis acupuncture needle", which was officially published as an international standard. The Suzhou Medical Supplies Factory developed from a manual workshop to an international standard maker.

  15. AN ASSESSMENT OF TOTAL FACTOR PRODUCTIVITY

    Directory of Open Access Journals (Sweden)

    Dana GÂRDU

    2011-10-01

    Full Text Available The high performing East Asian development model sparked controversies in the academia: its success was ascribed alternatively to nation-states, markets, and sociocultural factors. This paper undertakes a comparative assessment of the last two generations of submodels, i.e. ASEAN-4 and China, by quantifying and interpreting their total factor productivity (TFP using the Solow Model. Results show that capital accumulation was their major growth driver before the beginning of the millennium. Subsequently growth is led by technical change in ASEAN-32, and capital inputs respectively in late industrialising economies, i.e., China and the Philippines. The main differences between the two submodels consist in levels in growth rates and technical progress contributions, which are strongly sped up in China by transition and integration in global production networks. For ASEAN-4 average null or negligible TFP values in the 1990s point to structural vulnerabilities that surface during the Asian financial crisis. ASEAN-3’s recovery is led by technical change though.

  16. Variation in Students' Conceptions of Self-Assessment and Standards

    Directory of Open Access Journals (Sweden)

    Heng Kiat Kelvin Tan

    2011-01-01

    Full Text Available This paper reports the results of a phenomenographic study on the different ways that secondary students understood and utilized student self-assessment and how various ego types could affect the accuracy of self-assessment. The study sought to contribute to the growing literature which recognizes the critical role that students play in assessment processes, and in particular the different roles that they assume in student self-assessment. The results of the study provide insights into how different students experience self-assessment by articulating the variation in the perception and purposes of assessing one's own learning. This variation is depicted as a hierarchy of logically related students' conceptions of self-assessment.

  17. Assessing transportation infrastructure impacts on rangelands: test of a standard rangeland assessment protocol

    Science.gov (United States)

    Duniway, Michael C.; Herrick, Jeffrey E.; Pyke, David A.; Toledo, David

    2010-01-01

    Linear disturbances associated with on- and off-road vehicle use on rangelands has increased dramatically throughout the world in recent decades. This increase is due to a variety of factors including increased availability of all-terrain vehicles, infrastructure development (oil, gas, renewable energy, and ex-urban), and recreational activities. In addition to the direct impacts of road development, the presence and use of roads may alter resilience of adjoining areas through indirect effects such as altered site hydrologic and eolian processes, invasive seed dispersal, and sediment transport. There are few standardized methods for assessing impacts of transportation-related land-use activities on soils and vegetation in arid and semi-arid rangelands. Interpreting Indicators of Rangeland Health (IIRH) is an internationally accepted qualitative assessment that is applied widely to rangelands. We tested the sensitivity of IIRH to impacts of roads, trails, and pipelines on adjacent lands by surveying plots at three distances from these linear disturbances. We performed tests at 16 randomly selected sites in each of three ecosystems (Northern High Plains, Colorado Plateau, and Chihuahuan Desert) for a total of 208 evaluation plots. We also evaluated the repeatability of IIRH when applied to road-related disturbance gradients. Finally, we tested extent of correlations between IIRH plot attribute departure classes and trends in a suite of quantitative indicators. Results indicated that the IIRH technique is sensitive to direct and indirect impacts of transportation activities with greater departure from reference condition near disturbances than far from disturbances. Trends in degradation of ecological processes detected with qualitative assessments were highly correlated with quantitative data. Qualitative and quantitative assessments employed in this study can be used to assess impacts of transportation features at the plot scale. Through integration with remote

  19. Machine Learning to Assess Grassland Productivity in Southeastern Arizona

    Science.gov (United States)

    Ponce-Campos, G. E.; Heilman, P.; Armendariz, G.; Moser, E.; Archer, V.; Vaughan, R.

    2015-12-01

    We present preliminary results of machine learning (ML) techniques modeling the combined effects of climate, management, and inherent potential on productivity of grazed semi-arid grasslands in southeastern Arizona. Our goal is to support public land managers determine if agency management policies are meeting objectives and where to focus attention. Monitoring in the field is becoming more and more limited in space and time. Remotely sensed data cover the entire allotments and go back in time, but do not consider the key issue of species composition. By estimating expected vegetative production as a function of site potential and climatic inputs, management skill can be assessed through time, across individual allotments, and between allotments. Here we present the use of Random Forest (RF) as the main ML technique, in this case for the purpose of regression. Our response variable is the maximum annual NDVI, a surrogate for grassland productivity, as generated by the Google Earth Engine cloud computing platform based on Landsat 5, 7, and 8 datasets. PRISM 33-year normal precipitation (1980-2013) was resampled to the Landsat scale. In addition, the GRIDMET climate dataset was the source for the calculation of the annual SPEI (Standardized Precipitation Evapotranspiration Index), a drought index. We also included information about landscape position, aspect, streams, ponds, roads and fire disturbances as part of the modeling process. Our results show that in terms of variable importance, the 33-year normal precipitation, along with SPEI, are the most important features affecting grasslands productivity within the study area. The RF approach was compared to a linear regression model with the same variables. The linear model resulted in an r2 = 0.41, whereas RF showed a significant improvement with an r2 = 0.79. We continue refining the model by comparison with aerial photography and to include grazing intensity and infrastructure from units/allotments to assess the

  3. The Setting of Progressive Energy Efficiency Performance Standards for Products through the Ecodesign Directive

    Directory of Open Access Journals (Sweden)

    Dalhammar, Carl

    2016-06-01

    Full Text Available The European Union (EU sets mandatory energy efficiency standards for appliances and other energy-relevant products through the Ecodesign Directive. The standards set so far have improved energy efficiency in a very cost-effective way. The main aim of the Directive is to remove the worst performing products from the market. There is a discussion on the potential to set more progressive legal standards in order to more rapidly improve the energy efficiency of products, or even induce ‘technology forcing’, which can be defined as standards requiring technology that goes beyond what is currently available on the market. This contribution examines different legal design options to set progressive energy standards and discusses the advantages and drawbacks with applying stricter standard-setting. The European ecodesign standards for vacuum cleaners are analyzed as they provide a recent example of standards with elements of technology forcing.

    The US Family Smoking Prevention and Tobacco Control Act and WHO Framework Convention on Tobacco Control provide us with powerful tools to reduce the death and disease caused by the use of tobacco products. One tool that can contribute substantially toward this goal is the authority to establish performance standards for tobacco products. Conjointly with reducing levels of nicotine in cigarettes, performance and quality control standards need to be established for non-combusted tobacco products. Performance standards and incentives should be provided so that tobacco companies are compelled to manufacture and market products with very low or almost non-existent toxicity (eg, nicotine-only products).

    2015-01-01

    Objective:To study the influence of biological products on the levels of nitrogen and sulphur cycle bacteria in shrimp culture systems of West Bengal, India. Methods: The pond water and sediment samples were analyzed for physico-chemical parameters as per standard methods. The bacteria involved in ammonification, nitrification, denitrification, sulphate reduction and sulphur oxidation were enumerated by most probable number technique. Results:The semi-intensive and modified extensive shrimp farms used a variety of biological products during various stages of production. No biological products were used in traditional farms. The water and sediment samples of modified extensive system recorded significantly higher mean heterotrophic bacterial counts. The counts of ammonia, nitrite and sulphur oxidizers, and nitrate and sulphate reducers varied among the systems. The cycling of nitrogen and sulphur appeared to be affected with the intensification of culture practices. Conclusions:The application of biological products in certain systems helped to maintain the bacteria involved in nitrogen and sulphur cycles and safe levels of ammonia, nitrite and nitrate. An assessment of these metabolically active bacteria in shrimp culture ponds and the application of right kind microbial products would help ameliorate the organic pollution in shrimp aquaculture.

  7. Occupational health impacts of climate change: current and future ISO standards for the assessment of heat stress.

    Science.gov (United States)

    Parsons, Ken

    2013-01-01

    The current system of International Standards (ISO) is assessed to consider whether standards are fit for purpose for the future in the context of climate change. ISO 7243, ISO 7933 and ISO 9886 provide the current ISO system for the assessment of heat stress. These involve a simple monitoring index, an analytical approach and physiological monitoring, respectively. The system relies on accurate measurement of the thermal conditions experienced by the worker (ISO 7726); and estimations of metabolic heat production due to work (ISO 8996) and the thermal properties of clothing (ISO 9920). As well as standards for heat stress assessment, the full range of ISO standards and the physical environment is listed as well as current work and proposed standards. A particular 'gap' in anticipating requirements for ISO standards in the future is the link between meteorological data and ISO standards. This is important for predicting the global consequences of a changing climate and anticipating potential impacts on occupational health across countries and cultures.

  14. The Influence of Purchasing Context and Reversibility of Choice on Consumer Responses Toward Personalized Products and Standardized Products.

    Science.gov (United States)

    Choi, Jieun; Lee, Doo-Hee; Taylor, Charles R

    2016-04-01

    Existing research on personalization has found that consumers generally prefer personalized products over standardized ones. This study argued that consumer preference for personalized products is dependent on purchasing context and reversibility of choice. Results of an experiment conducted in this study found that consumers preferred personalized products when purchasing an item for personal use but preferred standardized products when purchasing an item as a gift. However, the effects of purchasing context were negated when consumers were given the assurance that personalized products could be returned (reversibility of choice); when presented with reversibility of choice, consumers preferred personalized products over standardized products regardless of purchasing context. Theoretical and managerial implications of these results were discussed.

Although schema for a phased approach to development exists and guidelines are available for study reporting, a coherent and comprehensive set of guideline for a definitive biomarker validation study design have not been delineated.Methods: We proposed PROBE study design, Prospective specimen collec-tion and Retrospective Blinded Evaluation, for pivotal definitive evaluation of the accuracy of a classification biomarker. A detailed formulation of all aspects of the design is provided. Four tables itemize aspects that relate to (i) the Clinical Context; (ii) Performance Criteria; (iii) the Biomarker test; and (iv) Study power and termination. Alternative designs and strategies were contrasted to illustrate the merit of PROBE design.Results: The ideas are applied to studies of biomarkers the intended use of which is for disease diagnosis, screening, or prognosis. Two EDRN valida-tion studies (breast cancer and prostate cancer) were used as examples to elucidate PROBE design.Conclusion: Common biases that pervade the biomarker research literaturewould be eliminated if these rigorous standards were followed closely. We urge the adoption of the design as standard of practice for pivotal evaluation of the classification accuracy ofbiomarkers.

    Capsicums, as a spice, have been known since the beginning of civilization and historically associated with the discovery of the New World. The genus Capsicum (Fam. Solanaceae) provides many varieties and adds color, pungency, and aroma to the cuisines of most of the world. From the pungent chilli, of interest also to pharmaceuticals, to the colorful paprika and the bell capsicums with its remarkable aroma, the genus has been of great interest for its chemistry and physiological action. Pungency as a sensory attribute, its evaluation, structure-activity relationship, and its increasing acceptance and preference by diverse populations of the world are of great interest to many research disciplines. In a comprehensive review of all aspects in four sequential parts, Part I deals with History, Botany, Cultivation, and Primary Processing (CRC Critical Review, Food Science and Nutrition). The Capsicums among the spices are second only to black pepper in trades both in volume and value. The production of the different forms of this spice as ground, specialty seasonings, and as the concentrated oleoresins through technologically advanced processes, proposed newer products, the standard to control quality of the different products, world production, trade, and prospects are reviewed in detail in this, Part II.

    Wolbachia is a large monophyletic genus of intracellular bacteria, traditionally detected using PCR assays. Its considerable phylogenetic diversity and impact on arthropods and nematodes make it urgent to assess the efficiency of these screening protocols. The sensitivity and range of commonly used PCR primers and of a new set of 16S primers were evaluated on a wide range of hosts and Wolbachia strains. We show that certain primer sets are significantly more efficient than others but that no single protocol can ensure the specific detection of all known Wolbachia infections.

    Full Text Available Introduction: Mycophenolic acid(MPA, a fungal mycotoxin, is produced by Penicillium brevicompactum and is used for the synthesis of immunosuppressive drugs in pharmaceutical industries. The present study was conducted to evaluate the possibility of mycophenolic acid(MPA production by standard strains of P. brevicompactum at laboratory level. Methods: Three strains of P. brevicompactum were provided from microbial culture collections. To stimulate MPA production, barley was used as culture medium, and dry heat, wet heat, and gamma radiation were used to sterilize the culture medium. Samples were taken from the culture medium at different intervals, and their MPA level was assessed by HPLC method. Results: P. brevicompactum strain which was prepared from Finland(VTT D-061157 was able to produce MPA more than two other strains(from Germany and Iran. The amount of MPA enhanced linearly until day 10, and after that became relatively constant. Gamma radiation was a suitable method to sterilize the substrate, and nylon bags were evaluated as an easy and cheap container for growing the fungus. Conclusion: Production of MPA with simple and cheap culture media to provide primary substance for immunosuppressive drugs such as mycophenolate mofetile and sodium mycophenolate would be possible.

    In order to permit the environmentally safe discharge of brines produced from oil wells in Pennsylvania to the surface waters of the Commonwealth and to rapidly brings as many wells as possible into compliance with the law, the Pennsylvania Oil and Gas Association (POGAM) approached the Pennsylvania State University to develop a program designed to demonstrate that a treatment process to meet acceptable discharge conditions and effluent limitations can be standardized for all potential stripper wells brine discharge. After the initial studies, the first phase of this project was initiated. A bench-scale prototype model was developed for conducting experiments in laboratory conditions. The experiments pursued in the laboratory conditions were focused on the removal of ferrous iron from synthetically made brine. Iron was selected as the primary heavy metals for studying the efficiency of the treatment process. The results of a number of experiments in the lab were indicative of the capability of the proposed brine treatment process in the removal of iron. Concurrent with the laboratory experiments, a comprehensive and extensive kinetic study was initiated. This study was necessary to provide the required data base for process modeling. This study included the investigation of the critical pH as well as the rate and order of reactions of the studied elements: aluminum, lead, zinc, and copper. In the second phase of this project, a field-based prototype was developed to evaluate and demonstrate the treatment process effectiveness. These experiments were conducted under various conditions and included the testing on five brines from different locations with various dissolved constituents. The outcome of this research has been a software package, currently based on iron`s reactivity, to be used for design purposes. The developed computer program was refined as far as possible using the results from laboratory and field experiments.

    Grain legume crops are a significant component of the human diet and animal feed and have an important role in the environment, but the global diversity of agricultural legume species is currently underexploited. Experimental assessments of grain legume performances are required, to identify potential species with high yields. Here, we introduce a dataset including results of field experiments published in 173 articles. The selected experiments were carried out over five continents on 39 grain legume species. The dataset includes measurements of grain yield, aerial biomass, crop nitrogen content, residual soil nitrogen content and water use. When available, yields for cereals and oilseeds grown after grain legumes in the crop sequence are also included. The dataset is arranged into a relational database with nine structured tables and 198 standardized attributes. Tillage, fertilization, pest and irrigation management are systematically recorded for each of the 8,581 crop*field site*growing season*treatment combinations. The dataset is freely reusable and easy to update. We anticipate that it will provide valuable information for assessing grain legume production worldwide. PMID:27676125

    2006-07-01

    Life cycle assessment (LCA) is used to evaluate the benefits, primarily from reduced energy consumption, resulting from the addition of a green roof to an eight story residential building in Madrid. Building energy use is simulated and a bottom-up LCA is conducted assuming a 50 year building life. The key property of a green roof is its low solar absorptance, which causes lower surface temperature, thereby reducing the heat flux through the roof. Savings in annual energy use are just over 1%, but summer cooling load is reduced by over 6% and reductions in peak hour cooling load in the upper floors reach 25%. By replacing the common flat roof with a green roof, environmental impacts are reduced by between 1.0 and 5.3%. Similar reductions might be achieved by using a white roof with additional insulation for winter, but more substantial reductions are achieved if common use of green roofs leads to reductions in the urban heat island.

    2015-04-01

    The Gamma distribution is classically fitted at monthly resolution to assess drought occurrence with respect to precipitation series. SPI estimation reports deviations from normal situations and allows the classification of months from extremely wet to extremely dry. However in case where time series contain zeros (no rainfall observed for some months) the choice of Gamma distribution is not appropriate. The objective of this study is compare Gamma distribution results to the loi des fuites distribution as alternative (Ref : Parent et al., Rev. Statistique Appliquée, 2006, LIV (4), 85-111 ). A network composed by 43 rainfall stations from the extreme North region of Tunisia (Mediterranean façade) using long series records (exceeding 30 years) is adopted to develop the methodology. the distributions for the 1- month, 3-months totals as well as 6 months totals and 12-months totals are adjusted station by station for both distributions and SPI-1, SPI-3, SPI-6 , SPI-12 are computed. It is found that especially for SPI-1 and SPI-3 that reflect meteorological drought, the decision status is well related to the underlined distribution which results in many operational concerns.

Methods: Mailed survey to EPs and a convenience sample of ED patients. Survey rated urgency of acute sore throat, ankle injury, abdominal pain, and hemiparesis, as well as the best definition of “emergency.” Responses were compared with chi-square (p < .05. Results: 119/140 (85% of EPs and 1453 ED patients responded. EPs were more likely to judge acute abdominal pain (79.8% vs. 43.4%, p < 0.001, odds ratio (OR 5.16, 95% confidence interval (CI 3.19-8.40 and hemiparesis (100% vs. 82.6%, p < 0.001, OR 24.9, 95% CI 3.75-94.4 as an emergency. Similar proportions of ED patients and EPs considered sore throat (12.2% vs. 7.6%, p = 0.18, OR 0.59, CI 0.27-1.23 and ankle injury (46.9% vs. 38.6%, p = 0.10, OR 0.71, CI 0.48-1.06 an emergency. EPs (35% and ED patients (40% agreed to a similar degree with the “prudent layperson” definition, “a condition that may result in death, permanent disability, or severe pain.” (p = .36, OR 1.22, CI 0.81-1.84. EPs were more likely to add, “the condition prevented work,” (27% vs. 16%, p = 0.003, OR 0.51, CI 0.33-0.81. Patients more often added, “occurred outside business hours” (15% vs. 4%, p = 0.002, OR 4.0, CI = 1.5-11.3. Conclusion: For serious complaints, ED patients’ thresholds for seeking care are higher than judged appropriate by EPs. Stroke is not uniformly recognized as an emergency. Absent consensus for the “correct” threshold, the prudent layperson standard is appropriate.

Methods Spatial learning and memory capacities of hPS2m transgenic mice were evaluated using the Morris Water Maze. Simultaneously, PM012 was repeatedly administered orally to male and female SD rats (15/sex/group at doses of 0 (vehicle control, 500, 1,000 and 2,000 mg/kg/day for 4 or 26 weeks. To evaluate the recovery potential, 5 animals of each sex were assigned to vehicle control and 2,000 mg/kg/day groups during the 4-week recovery period. Results The results showed that PM012-treated hPS2m transgenic mice showed significantly reduced escape latency when compared with the hPS2m transgenic mice. The repeated oral administration of PM012 over 26 weeks in male and female rats induced an increase and increasing trend in thymus weight in the female treatment groups (main and recovery groups, but the change was judged to be toxicologically insignificant. In addition, the oral administration of the herbal medicine PM012 did not cause adverse effects as assessed by clinical signs, mortality, body weight, food and water consumption, ophthalmology, urinalysis, hematology, serum biochemistry, blood clotting time, organ weights and histopathology. The No Observed Adverse Effects Levels of PM012 was determined to be 2,000 mg/kg/day for both sexes, and the target organ was not identified. Conclusion These results suggest that PM012 has potential for use in the treatment of the Alzheimer's disease without serious adverse effects.

    2015-08-01

    In the past decade, many guidance documents have been issued through collaboration of global organizations and regulatory authorities. Most of these are applicable to new products, but there is a risk that currently marketed products will not meet the new compliance standards during audits and inspections while companies continue to make changes through the product life cycle for continuous improvement or market demands. This discussion presents different strategies to bringing drug product marketing applications to meet current and emerging standards. It also discusses stability and method designs to meet process validation and global development efforts.

  1. The cultural appropriateness and diagnostic usefulness of standardized language assessments for Indigenous Australian children.

    Science.gov (United States)

    Pearce, Wendy M; Williams, Cori

    2013-08-01

    Speech-language pathologists experience uncertainty about how to interpret standardized assessment results for Indigenous Australian children. There are risks for inappropriate diagnosis: both over- and under-diagnosis of language impairment may occur due to a convergence of linguistic features which causes difficulty in distinguishing between impairment and difference. While the literature suggests that standardized assessments are inappropriate for Indigenous Australian children, there is an absence of empirical documentation to show how Indigenous children perform on standardized tests of language ability. This study examined the performance of 19 Indigenous Australian children, aged 8;01-13;08, from one school on the Clinical Evaluation of Language Fundamentals, Fourth Edition, Australian Standardized Edition. Standardized scores were compared with teacher ratings of children's oral language skills. Analysis showed poor alignment between teacher ratings and language assessment, and assessment scores were negatively influenced by features of Aboriginal English. Children rated with above average language skills presented with different linguistic profiles from the children rated with average and below average language abilities. The inappropriateness of current standardized language assessments for Indigenous children and the need for further research to guide appropriate assessment are discussed.

    2015-07-01

    Full Text Available What language should be featured in assessment standards for international students? Have universities adjusted their assessment methods sufficiently to match the increased demand for studying abroad? How might art and design benefit from a more stable definition of standards? These are some questions this paper seeks to address by reporting the results of recent pedagogic research at the School of the Arts, Loughborough University, in the United Kingdom. Language use is at the heart of this issue, yet it is generally overlooked as an essential tool that links assessment, feedback and action planning for international students. The paper reveals existing and new data that builds on research since 2009, aimed at improving students’ assessment literacy. Recommendations are offered to stimulate local and global discussion about keyword use for defining undergraduate assessment standards in art and design.

    2006-01-01

    Based on the analysis on the status quo of natural resources input in grain production and on the policy of grain subsidies, this paper puts forward a new idea - establishing grain subsidies through assessing the value of the natural resources in grain production. The assessment of the natural resources in grain production provides rationale and reference standard for the policy of grain subsidies, which will promote the sustainable use of natural resources accordingly. This paper concludes: (1) it is necessary for the grain subsidies to assess the full value of natural resources,including economic value, ecological value and social value; (2) the government should give farmers direct subsidies or environment subsidies according to the economic and ecological value of natural resources in grain production; (3) the social value of natural resources can be realized by establishing the country social security system, taking the social value as the criterion for the payment for part of farmers insurance.

    2014-05-16

    In recent years, the official regulation of chemicals and chemical products has been intensified. Explicitly for spray products enhanced requirements to assess the consumers'/professionals' exposure to such product type have been introduced. In this regard the Aerosol-Dispensers-Directive (75/324/EEC) with obligation for marketing aerosol dispensers, and the Cosmetic-Products-Regulation (1223/2009/EC) which obliges the insurance of a safety assessment, have to be mentioned. Both enactments, similar to the REACH regulation (1907/2006/EC), require a robust chemical safety assessment. From such assessment, appropriate risk management measures may be identified to adequately control the risk of these chemicals/products to human health and the environment when used. Currently, the above-mentioned regulations lack the guidance on which data are needed for preparing a proper hazard analysis and safety assessment of spray products. Mandatory in the process of inhalation risk and safety assessment is the determination and quantification of the actual exposure to the spray product and more specifically, its ingredients. In this respect the current article, prepared by the European Aerosol Federation (FEA, Brussels) task force "Inhalation Toxicology", intends to introduce toxicological principles and the state of the art in currently available exposure models adapted for typical application scenarios. This review on current methodologies is intended to guide safety assessors to better estimate inhalation exposure by using the most relevant data.

    The main contributions of this study are to conduct a comparative thermodynamic analysis of methane reforming reactions and to asses the influence of key operational variables on chemical equilibrium using an in-house code, developed in the open-source software Scilab{sup c} INRIA-ENPC (www.scilab.org). Equilibrium compositions are calculated by two distinct methods: evaluation of equilibrium constants and Lagrange multipliers. Both methods result in systems of non-linear algebraic equations, solved numerically using the Scilab function 'fsolve'. Comparison between experimental and simulated equilibrium data, published in the literature, was used to validate the simulated results. Effects of temperature, pressure, initial H{sub 2}O/CH{sub 4} ratio (steam reforming), initial CH{sub 4}:CO{sub 2}:N{sub 2} ratio (dry reforming) and initial O{sub 2}/CH{sub 4} ratio (partial oxidation) on the reaction products were evaluated.

  4. Planning the Unplanned Experiment: Towards Assessing the Efficacy of Standards for Safety-Critical Software

    Graydon, Patrick J.; Holloway, C. M.

    2015-01-01

    Safe use of software in safety-critical applications requires well-founded means of determining whether software is fit for such use. While software in industries such as aviation has a good safety record, little is known about whether standards for software in safety-critical applications 'work' (or even what that means). It is often (implicitly) argued that software is fit for safety-critical use because it conforms to an appropriate standard. Without knowing whether a standard works, such reliance is an experiment; without carefully collecting assessment data, that experiment is unplanned. To help plan the experiment, we organized a workshop to develop practical ideas for assessing software safety standards. In this paper, we relate and elaborate on the workshop discussion, which revealed subtle but important study design considerations and practical barriers to collecting appropriate historical data and recruiting appropriate experimental subjects. We discuss assessing standards as written and as applied, several candidate definitions for what it means for a standard to 'work,' and key assessment strategies and study techniques and the pros and cons of each. Finally, we conclude with thoughts about the kinds of research that will be required and how academia, industry, and regulators might collaborate to overcome the noted barriers.

  5. Assessment of standard compliance of Central European plastics-based wall cladding using multi-criteria decision making (MCDM

    Directory of Open Access Journals (Sweden)

    Daniel Friedrich

    2016-06-01

    Full Text Available Plastics are increasingly combined with renewable fibers to form materials such as wood-plastic composites (WPCs. These bio-based materials have gained the interest of the resource-intensive building industry and are currently used mainly for decking and cladding. Despite their environmental friendliness, WPC façades are still underrepresented in the market. This fact raises the question of whether WPC cladding is currently well positioned in the market and whether its attributes are advertised in a way that makes it stand out in a material selection process. A review of standards and codes relevant to façade design was carried out in this study, which allowed the identification of 21 product attributes as potential deciding factors in cladding product selection. Subsequently, the most promising attributes were used to assess commercially available plastics-based cladding products. By using multi-criteria decision making (MCDM it was found that WPC cladding is still far behind other cladding products with respect to standard compliance but has specific properties which support product optimization. MCDM can be used by WPC cladding manufacturers for strategic product development and by façade designers for material selection processes.

  9. Emission standards versus immission standards for assessing the impact of urban drainage on ephemeral receiving water bodies.

    Science.gov (United States)

    Freni, Gabriele; Mannina, Giorgio; Viviani, Gaspare

    2010-01-01

    In the past, emission standard indicators have been adopted by environmental regulation authorities in order to preserve the quality of a receiving water body. Such indicators are based on the frequency or magnitude of a polluted discharge that may be continuous or intermittent. In order to properly maintain the quality of receiving waters, the Water Framework Directive, following the basic ideas of British Urban Pollution Manual, has been established. The Directive has overtaken the emission-standard concept, substituting it with the stream-standard concept that fixes discharge limits for each polluting substance depending on the self-depurative characteristics of receiving waters. Stream-standard assessment requires the deployment of measurement campaigns that can be very expensive; furthermore, the measurement campaigns are usually not able to provide a link between the receiving water quality and the polluting sources. Therefore, it would be very useful to find a correlation between the quality status of the natural waters and the emission-based indicators. Thus, this study is aimed to finding a possible connection between the receiving water quality indicators drawn by environmental regulation authorities and emission-based indicators while considering both continuous (i.e. from the wastewater treatment plants) and intermittent pollution discharges (mainly from combined sewer overflows). Such research has been carried out by means of long-term analysis adopting a holistic modelling approach. The different parts of the integrated urban drainage system were modelled by a parsimonious integrated model. The analysis was applied to an ephemeral river bounding Bologna (Italy). The study concluded that the correlation between receiving water quality and polluting emissions cannot be generally stated. Nevertheless, specific analyses on polluting emissions were pointed out in the study highlighting cause-effect link between polluting sources and receiving water quality.

    The oil palm seed production unit that generates germinated oil palm seeds is the first link in the palm oil supply chain, followed by the nursery to produce seedling, the plantation to produce fresh fruit bunches (FFB), the mill to produce crude palm oil (CPO) and palm kernel, the kernel crushers to produce crude palm kernel oil (CPKO), the refinery to produce refined palm oil (RPO) and finally the palm biodiesel plant to produce palm biodiesel. This assessment aims to investigate the life cycle assessment (LCA) of germinated oil palm seeds and the use of LCA to identify the stage/s in the production of germinated oil palm seeds that could contribute to the environmental load. The method for the life cycle impact assessment (LCIA) is modelled using SimaPro version 7, (System for Integrated environMental Assessment of PROducts), an internationally established tool used by LCA practitioners. This software contains European and US databases on a number of materials in addition to a variety of European- and US-developed impact assessment methodologies. LCA was successfully conducted for five seed production units and it was found that the environmental impact for the production of germinated oil palm was not significant. The characterised results of the LCIA for the production of 1000 germinated oil palm seeds showed that fossil fuel was the major impact category followed by respiratory inorganics and climate change.

  11. The Role of Self- and Peer Assessment in Dental Students' Reflective Practice Using Standardized Patient Encounters.

    2016-08-01

    The aim of this study was to gain insight into the nature of the role played by self- and peer assessment in the development of dental students' reflective practice skills and the value gained through structured encounters with standardized patients. Four standardized patient encounters in an objective structured clinical exam (OSCE) format served as a learning experience for students to demonstrate decision making and communication skills in complex scenarios regarding issues of ethics. Self- and peer assessment and peer-to-peer discourse were used to enhance student reflection. A sample of 16 peer pairs was randomly selected from the population of 108 fourth-year students who participated in the 2014 Clinical Dental Ethics OSCE. Data were collected from self- and peer assessment forms. Five overall performance themes (personal affect, verbal communication, professional demeanor, relationship-building, and patient management) and three student learning themes (application and knowledge, ways to change, and impressed with peer/increased confidence in self) were identified. The results showed that peer assessment ratings were consistently higher than those in the self-assessments, but overall the students deemed both their peers' and their own decision making and communication skills to be quite good. These students rated their experience with the OSCE and self- and peer assessments as positive, appreciating the importance of reflection and learning from their peers. These results provide support for the continued formative use of standardized patient OSCEs and self- and peer assessment to help students develop skills in decision making, communication, professionalism, and reflection.

    The present study investigated angiographic emulation of multislice computed tomography (MSCT) (catheter-like visualization) as an alternative approach of analyzing and visualizing findings in comparison with standard assessment. Thirty patients (120 coronary arteries) were randomly selected from 90 prospectively investigated patients with suspected coronary artery disease who underwent MSCT (16-slice scanner, 0.5 mm collimation, 400 ms rotation time) prior to conventional coronary angiography for comparison of both approaches. Sensitivity and specificity of angiographic emulation [81% (26/32) and 93% (82/88)] were not significantly different from those of standard assessment [88% (28/32) and 99% (87/88)], while the per-case analysis time was significantly shorter for angiographic emulation than for standard assessment (3.4 {+-} 1.5 vs 7.0 {+-} 2.5 min, P < 0.001). Both interventional and referring cardiologists preferred angiographic emulation over standard curved multiplanar reformations of MSCT coronary angiography for illustration, mainly because of improved overall lucidity and depiction of sidebranches (P < 0.001). In conclusion, angiographic emulation of MSCT reduces analysis time, yields a diagnostic accuracy comparable to that of standard assessment, and is preferred by cardiologists for visualization of results.

  14. Assessing Quality of Data Standards: Framework and Illustration Using XBRL GAAP Taxonomy

    Science.gov (United States)

    Zhu, Hongwei; Wu, Harris

    The primary purpose of data standards or metadata schemas is to improve the interoperability of data created by multiple standard users. Given the high cost of developing data standards, it is desirable to assess the quality of data standards. We develop a set of metrics and a framework for assessing data standard quality. The metrics include completeness and relevancy. Standard quality can also be indirectly measured by assessing interoperability of data instances. We evaluate the framework using data from the financial sector: the XBRL (eXtensible Business Reporting Language) GAAP (Generally Accepted Accounting Principles) taxonomy and US Securities and Exchange Commission (SEC) filings produced using the taxonomy by approximately 500 companies. The results show that the framework is useful and effective. Our analysis also reveals quality issues of the GAAP taxonomy and provides useful feedback to taxonomy users. The SEC has mandated that all publicly listed companies must submit their filings using XBRL. Our findings are timely and have practical implications that will ultimately help improve the quality of financial data.

It draws on a survey of PCF......-15 years, there is a danger that developing country exporters will lose out as a result. This is because: they are less likely to have the resources necessary for calculating and verifying PCFs; publicly available datasets are less likely to include processes carried out mainly in developing countries......; and some existing standards do not currently include production of capital goods in their definition of product life cycles, which imparts a bias against labour-intensive production methods and hence against typical developing country exports.

    The Bureau of Products and Standards (BPS), a redefinition of the former Bureau for Standards and Conventions (BSC), supports the Global Geodetic Observing System (GGOS) in its goal to obtain geodetic products of highest accuracy and consistency. In order to fully benefit from the ongoing technological improvements of the observing systems contributing to GGOS, it is essential that the analysis of the precise space geodetic observations is based on the definition of common standards and conventions and a unique representation and parameterization of the relevant quantities. This is of crucial importance for the establishment of highly accurate and consistent geodetic reference frames, as the basis for a reliable monitoring of the time-varying shape, rotation and gravity field of the Earth.A major focus was on the compilation of an inventory based on the evaluation of the standards and conventions currently in use by the IAG Services and their contributing analysis centres and for the generation of geometric and gravimetric products, such as geodetic reference frames, Earth orientation parameters, gravity field models and satellite orbits. This product-based inventory presents the current status concerning standards and conventions, indicating that there are several inconsistencies. As a major outcome of this inventory, the BPS will provide recommendations on how to resolve inconsistencies and gaps. In this presention we will briefly report on the mentioned activities and we summarize the most important findings.

    2014-06-01

    This work presents a techno-economic and environmental assessment of the glucose syrups production from sugarcane bagasse, plantain husk, cassava husk, mango peel, rice husk and corncobs. According to the economic analysis, the corncob had both, the lowest production cost (2.48USD/kg syrup) and the highest yield (0.61kgofsugars/kg of wet agroindustrial waste) due to its high content in cellulose and hemicellulose. This analysis also revealed that a heat integration strategy is necessary since the utilities consumption represent an important factor in the production cost. According to the results, the pretreatment section requires more energy in the syrup production in comparison with the requirements of other sections such as production and sugar concentration. The environmental assessment revealed that the solid wastes such as furfural and hydroxymethylfurfural affected the environmental development of the process for all the agroindustrial wastes, being the rice husk the residue with the lowest environmental impact.

    With the improvement of living standards, people pay more attention to the agricultural products with health protection function, and the selenium-rich agricultural products attract more and more consumers. The main biological role of selenium is to resist oxidation and inflammatory response, mainly focusing on resisting aging, preventing cardiovascular disease, protecting eyesight, counteracting or destroying the toxic properties, preventing cancer and thyroid disease. In most areas of China, there is a widespread shortage of selenium, thus producing selenium-rich agricultural products to provide natural selenium-rich health food to the areas in need of selenium, has gradually become a new hot spot of China’s health food industry, but high content of selenium in food is detrimental to human body, even leads to selenium intoxication, and artificially adding inorganic selenium is difficult to guarantee that the selenium content of agricultural products is not exceeded. According to human body’s daily demand for selenium in dietetics and the content of selenium in agricultural products in the Chinese food composition table, we put forward the recommendations on the standard of selenium in agricultural products, in order to provide the basis for China to formulate the health standard of selenium content in selenium-rich agricultural products.

  1. Reconsidering the risk assessment concept: Standardizing the impact description as a building block for vulnerability assessment

    Directory of Open Access Journals (Sweden)

    K. Hollenstein

    2005-01-01

    Full Text Available Risk assessments for natural hazards are becoming more widely used and accepted. Using an extended definition of risk, it becomes obvious that performant procedures for vulnerability assessments are vital for the success of the risk concept. However, there are large gaps in knowledge about vulnerability. To alleviate the situation, a conceptual extension of the scope of existing and new models is suggested. The basis of the suggested concept is a stadardization of the output of hazard assessments. This is achieved by defining states of the target objects that depend on the impact and at the same time affect the object's performance characteristics. The possible state variables can be related to a limited set of impact descriptors termed generic impact description interface. The concept suggests that both hazard and vulnerability assessment models are developed according to the specification of this interface, thus facilitating modularized risk assessments. Potential problems related to the application of the concept include acceptance issues and the lacking accuracy of transformation of outputs of existing models. Potential applications and simple examples for adapting existing models are briefly discussed.

  2. Emerging product carbon footprint standards and schemes and their possible trade impacts

    2009-12-15

    Concern over climate change has stimulated interest in estimating the total amount of greenhouse gasses produced during the life-cycle of goods and services - i.e. during their production, transportation, sale, use and disposal. The outcome of these calculations is referred to as 'product carbon footprints' (PCFs). The paper reviews the rationale, context, coverage and characteristics of emerging standards and certification schemes that estimate and designate PCFs, and discusses the possible impacts on trade, particularly exports from distant and developing countries. It draws on a survey of PCF certification schemes carried out during 2009, on a review of evolving international and national standards, and on a review of consumer surveys. Since 2007 one public standard, and two public and 14 private certification schemes referring to standards for calculating and communicating PCFs have become operational. Two new international standards and several new schemes, including three public ones, are due to become operational by 2011 or earlier. The private schemes are owned by a mixture of voluntary bodies and private companies, including some large retailers. Many provide assistance for reducing carbon footprints or procedures for certification or labelling. Nonetheless, to date only a few thousand products have been footprinted. As PCFs are already becoming market access requirements for bio-fuels imported to the EU, and may also become EU market access requirements for all mass-produced goods within 10-15 years, there is a danger that developing country exporters will lose out as a result. This is because: they are less likely to have the resources necessary for calculating and verifying PCFs; publicly available datasets are less likely to include processes carried out mainly in developing countries; and some existing standards do not currently include production of capital goods in their definition of product life cycles, which imparts a bias against

    The Geoscience Laser Altimeter System (GLAS) is the primary instrument for the ICESat (Ice, Cloud and Land Elevation Satellite) laser altimetry mission. ICESat was the benchmark Earth Observing System (EOS) mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics. From 2003 to 2009, the ICESat mission provided multi-year elevation data needed to determine ice sheet mass balance as well as cloud property information, especially for stratospheric clouds common over polar areas. It also provided topography and vegetation data around the globe, in addition to the polar-specific coverage over the Greenland and Antarctic ice sheets.This document contains the data dictionary for the GLAS standard data products. It details the parameters present on GLAS standard data products. Each parameter is defined with a short name, a long name, units on product, type of variable, a long description and products that contain it. The term standard data products refers to those EOS instrument data that are routinely generated for public distribution. These products are distributed by the National Snow and Ice Data Center (NSDIC).

  4. World Biofuels Production Potential Understanding the Challenges to Meeting the U.S. Renewable Fuel Standard

    2008-09-15

    This study by the U.S. Department of Energy (DOE) estimates the worldwide potential to produce biofuels including biofuels for export. It was undertaken to improve our understanding of the potential for imported biofuels to satisfy the requirements of Title II of the 2007 Energy Independence and Security Act (EISA) in the coming decades. Many other countries biofuels production and policies are expanding as rapidly as ours. Therefore, we modeled a detailed and up-to-date representation of the amount of biofuel feedstocks that are being and can be grown, current and future biofuels production capacity, and other factors relevant to the economic competitiveness of worldwide biofuels production, use, and trade. The Oak Ridge National Laboratory (ORNL) identified and prepared feedstock data for countries that were likely to be significant exporters of biofuels to the U.S. The National Renewable Energy Laboratory (NREL) calculated conversion costs by conducting material flow analyses and technology assessments on biofuels technologies. Brookhaven National Laboratory (BNL) integrated the country specific feedstock estimates and conversion costs into the global Energy Technology Perspectives (ETP) MARKAL (MARKet ALlocation) model. The model uses least-cost optimization to project the future state of the global energy system in five year increments. World biofuels production was assessed over the 2010 to 2030 timeframe using scenarios covering a range U.S. policies (tax credits, tariffs, and regulations), as well as oil prices, feedstock availability, and a global CO{sub 2} price. All scenarios include the full implementation of existing U.S. and selected other countries biofuels policies (Table 4). For the U.S., the most important policy is the EISA Title II Renewable Fuel Standard (RFS). It progressively increases the required volumes of renewable fuel used in motor vehicles (Appendix B). The RFS requires 36 billion (B) gallons (gal) per year of renewable fuels by 2022

    1990-02-01

    Ecological monitoring data that could provide indications of agroecosystem condition, such as soil microbial biomass, biodiversity in the patches or mineralizable-N, are not available on a national scale. This paper discusses the economists' and ecologists' approach to assessing agroecosystem productivity, and the data available to make ecological assessments of agroecosystems on a national level. Models and indices of productivity used by ecologists and economists are briefly discussed in the context of agricultural inputs and outputs. Databases on production, pesticides, fertilizers, water use, water and air quality, land use, soil, labor and machinery are evaluated for their ability to make national trend assessments on how this ecosystem responds to stress. 39 refs., 3 figs., 3 tabs.

    Directory of Open Access Journals (Sweden)

    Prikhoda N.A.,

    2016-10-01

    Full Text Available The article describes the Russian Language Development Assessment, a standardized individual diagnostic tool for children aged from 3 to 9 that helps to assess the following components of a child’s communicative function: passive vocabulary, expressive vocabulary, knowledge of semantic constructs with logical, temporal and spatial relations, passive perception and active use of syntactic and morphological features of words in a sentence, active and passive phonological awareness, active and passive knowledge of syntactic structures and categories. The article provides descriptions of content and diagnostic procedures for all 7 subtests included in the assessment (Passive Vocabulary, Active Vocabulary, Linguistic Operators, Sentence structure, Word Structure, Phonology, Sentence Repetition. Basing on the data collected in the study that involved 86 first- graders of a Moscow school, the article analyzes the internal consistency and construct validity of each subtest of the technique. It concludes that the Russian Language Development Assessment technique can be of much use both in terms of diagnostic purposes and in supporting children with ASD taking into account the lack of standardized tools for language and speech development assessment in Russian and the importance of this measure in general.

    This article will outline a pragmatic approach directed to incorporating key elements of a scientific review of the literature and derive a proposal for an occupational exposure standard for coal tar, coal tar pitch, creosote, petroleum pitch, bitumen and asphalt, six substances which contain polynuclear aromatic hydrocarbons. Five approaches to the standard setting process are reviewed and their strengths and weaknesses discussed. Unfortunately there does not exist an acceptable epidemiological data set, other than the coke oven emission studies, on which to base a valid and reliable risk assessment model. Based on comparative potency experiments of complex mixtures, consideration of the state-of-the-art sampling and analytical methods, prevention of acute human health effects, and current existing standards for these substances throughout the world, a set of recommended exposure standards are derived for health policy makers.

    This paper describes the background, principles, concepts and methods of framing the technical regulation for edible safety requirement and assessment of agricultural genetically modified organisms (agri-GMOs) for Shenzhen Special Economic Zone in the People's Republic of China. It provides a set of systematic criteria for edible safety requirements and the assessment process for agri-GMOs. First, focusing on the degree of risk and impact of different agri-GMOs, we developed hazard grades for toxicity, allergenicity, anti-nutrition effects, and unintended effects and standards for the impact type of genetic manipulation. Second, for assessing edible safety, we developed indexes and standards for different hazard grades of recipient organisms, for the influence of types of genetic manipulation and hazard grades of agri-GMOs. To evaluate the applicability of these criteria and their congruency with other safety assessment systems for GMOs applied by related organizations all over the world, we selected some agri-GMOs (soybean, maize, potato, capsicum and yeast) as cases to put through our new assessment system, and compared our results with the previous assessments. It turned out that the result of each of the cases was congruent with the original assessment.

  11. Towards continuous improvement of endoscopy standards: Validation of a colonoscopy assessment form.

    LENUS (Irish Health Repository)

    2012-02-01

    Aim: Assessment of procedural colonoscopy skills is an important and topical. The aim of this study was to develop and validate a competency-based colonoscopy assessment form that would be easy to use, suitable for the assessment of junior and senior endoscopists and potentially be a useful instrument to detect differences in performance standards following different training interventions. Method: A standardised assessment form was developed incorporating a checklist with dichotomous yes\\/no responses and a global assessment section incorporating several different elements. This form was used prospectively to evaluate colonoscopy cases during the period of the study in several university teaching hospitals. Results were analysed using ANOVA with Bonferroni corrections for post-hoc analysis. Results: 81 procedures were assessed, performed by eight consultant and 19 trainee endoscopists. There were no serious errors. When divided into three groups based on previous experience (novice, intermediate and expert) the assessment form demonstrated statistically significant differences between all three groups (p<0.05). When separate elements were taken into account, the global assessment section was a better discriminator of skill level than the checklist. Conclusion: This form is a valid, easy to use assessment method. We intend to use it to assess the value of simulator training in trainee endoscopists. It also has the potential to be a useful training tool when feedback is given to the trainee.

  13. ON JUSTIFICATION OF STANDARDS FOR NATURAL RADIONUCLIDE CONCENTRATION IN FACING PRODUCTS AND MATERIALS

    Directory of Open Access Journals (Sweden)

    I. P. Stamat

    2009-01-01

    Full Text Available The article addresses issues of the population radiation protection regulatory framework development for the natural sources of radiation. Calculations for justification of standard for natural radionuclide concentration in the wide range of contemporary building materials - facing products - are formulated. The basic consideration of calculations is that implementation of these products could lead to the additional population exposure from natural sources less than 0,1 mSv/year. On the base of this assumption it is shown that effective specific activity of natural radionuclides in these products must not exceed 740 Bq/kg.

    2014-06-01

    Standard industry processes for recombinant antibody production employ protein A affinity chromatography in combination with other chromatography steps and ultra-/diafiltration. This study compares a generic antibody production process with a recently developed purification process based on a series of selective precipitation steps. The new process makes two of the usual three chromatographic steps obsolete and can be performed in a continuous fashion. Cost of Goods (CoGs) analyses were done for: (i) a generic chromatography-based antibody standard purification; (ii) the continuous precipitation-based purification process coupled to a continuous perfusion production system; and (iii) a hybrid process, coupling the continuous purification process to an upstream batch process. The results of this economic analysis show that the precipitation-based process offers cost reductions at all stages of the life cycle of a therapeutic antibody, (i.e. clinical phase I, II and III, as well as full commercial production). The savings in clinical phase production are largely attributed to the fact that expensive chromatographic resins are omitted. These economic analyses will help to determine the strategies that are best suited for small-scale production in parallel fashion, which is of importance for antibody production in non-privileged countries and for personalized medicine.

  16. Single top production at next-to-leading order in the Standard Model effective field theory

    CERN Document Server

    Zhang, Cen

    2016-01-01

    Single top production processes at hadron collider provide information on the relation between the top quark and the electroweak sector of the standard model. We compute the next-to-leading order QCD corrections to the three main production channels: $t$-channel, $s$-channel and $tW$ associated production, in the standard model including operators up to dimension-six. The calculation can be matched to parton shower programs and can therefore be directly used in experimental analyses. The QCD corrections are found to significantly impact the extraction of the current limits on the operators, because both of an improved accuracy and a better precision of the theoretical predictions. In addition, the distributions of some of the key discriminating observables are modified in a nontrivial way, which could change the interpretation of measurements in terms of UV complete models.

  17. Waste management through life cycle assessment of products

    2015-04-01

    The rapid growth of a population in a country can contribute to high production of waste. Municipal waste and industrial waste can bring unhealthy and unpleasant environment or even diseases to human beings if the wastes are not managed properly.With increasing concerns over waste and the need for ‘greener’ products, it is necessary to carry out Life Cycle Assessments of products and this will help manufacturers take the first steps towards greener designs by assessing their product's carbon output. Life Cycle Assessment (LCA) is a process to evaluate the environmental burdens associated with a product, process or activity by identifying and quantifying energy and materials used and wastes released to the environment, and to assess the impact of those energy and material used and released to the environment. The aim of the study was to use a life cycle assessment approach to determine which waste disposal options that will substantially reduce the environmental burdens posed by the Polyethylene Terephthalate (PET) bottle. Several important observations can be made. 1) Recycling of the PET bottle waste can significantly reduce the energy required across the life cycle because the high energy inputs needed to process the requisite virgin materials greatly exceeds the energy needs of the recycling process steps. 2) Greenhouse gases can be reduced by opting for recycling instead of landfilling and incineration. 3) Quantity of waste emissions released from different disposal options was identified. 4) Recycling is the environmentally preferable disposal method for the PET bottle. Industry can use the tools and data in this study to evaluate the health, environmental, and energy implications of the PET bottle. LCA intends to aid decision-makers in this respect, provided that the scientific underpinning is available. Strategic incentives for product development and life cycle management can then be developed.

    Dennis, J E

    1997-12-01

    Federal law requires that all laser products that are imported into or introduced into commerce in the United States comply with the performance standard published in the Code of Federal Regulations (CRF), Title 21, Parts 1040.10 and 1040.11, administered by the Center for Devices and Radiological Health (CDRH), US Food and Drug Administration. Although it contains somewhat different requirements for hazard classification, engineering controls and labeling, the ANSI Z136.1 standard defers to the CDRH standard. The CDRH standard became effective in August, 1976 and was amended, in 1978 and also in 1985. In the early 1990s, US experts met to formulate an approach to bring the requirements of the CDRH standard and those of the International Electrotechnical Commission (IEC) standard, IEC 825, into closer agreement in order to lower barriers to international trade and to remove any excessive compliance burdens on manufacturers. In 1993, the CDRH published, formally in the Federal Register and informally, a Notice of Intent to amend the CDRH standard. Responses to those notices have now been analyzed and informal draft amendments were distributed in 1996. This draft is now being prepared for formal issuance as a Notice of Proposed Rulemaking. Meanwhile, the IEC standard was amended in 1993 and republished as IEC 825-1; these amendments created considerable controversy since they resulted in over classification of the hazard of many products, especially light emitting diodes (LEDs) that have a large divergence and increased source dimensions. Additional amendments are now being developed to correct this problem. The CDRH has carefully monitored developments in the IEC and actively participated in its proceedings as a guide in developing its own proposal. This paper describes the major changes that are being proposed for the CDRH standard and presents some rationale for the major changes. The more significant changes include expansion of applicability to include LEDs

    2013-09-01

    Full Text Available Delivery of geospatial information over the Internet for the management of risks from invasive alien species is an increasingly important service. The evolution of information technology standards for geospatial data is a key factor to simplify network publishing and exchange of maps and data. The World Wide Web Consortium (W3C-geolocation specification is a recent addition that may prove useful for pest risk management. In this article we implement the W3C-geolocation specification and Open Geospatial Consortium (OGC mapping standards in a Web browser application for smartphones and tablet computers to improve field surveys for alien invasive species. We report our first season field experiences using this tool for online mapping of plant disease outbreaks and host plant occurrence. It is expected that the improved field data collection tools will result in increased data availability and thereby new opportunities for risk assessment, because data-needs and availability are crucial for species distribution modelling and model-based forecasts of pest establishment potential. Finally, we close with a comment on the future potential of geospatial information standards to enhance the translation from data to decisions regarding pest risks, which should enable earlier detection of emerging risks as well as more robust projections of pest risks in novel areas. The forthcoming standard for processing of geospatial information, the Web Processing Standard (WPS, should open new technological capabilities both for automatic initiation and updating of risk assessment models based on new incoming data, and subsequent early warning.

    2012-08-01

    Competency to stand trial relates directly to legal rights of the appraised individual as well as whether criminal procedure can be carried out smoothly. Foreign scholars have conducted a large number of theoretical researches, and developed a series of standardized evaluation tools. However, the assessment on competency to stand trial has mainly focused on medical criteria in China for a long time, and most cases were judged by forensic psychiatrists' experience. Recently, Chinese scholars have started the initial research on standardized evaluation. This paper reviews the notion of competency to stand trial, the evaluation criteria, and the assessment tools domestically and abroad. The main focus is on foreign assessment tools, which included three categories. First category includes checklist, self-report questionnaires and sentence-completion tasks. Second category is the interview-based instruments without criterion-based scoring. Last category is the interview-based instruments with criterion-based scoring. This literature may be helpful for further research and standardization on assessment tools of competency to stand trial of mentally disordered offenders.

    School violence has increased over the past decade and innovative, sensitive, and standardized approaches to assess school violence risk are needed. In our current feasibility study, we initialized a standardized, sensitive, and rapid school violence risk approach with manual annotation. Manual annotation is the process of analyzing a student's transcribed interview to extract relevant information (e.g., key words) to school violence risk levels that are associated with students' behaviors, attitudes, feelings, use of technology (social media and video games), and other activities. In this feasibility study, we first implemented school violence risk assessments to evaluate risk levels by interviewing the student and parent separately at the school or the hospital to complete our novel school safety scales. We completed 25 risk assessments, resulting in 25 transcribed interviews of 12-18 year olds from 15 schools in Ohio and Kentucky. We then analyzed structured professional judgments, language, and patterns associated with school violence risk levels by using manual annotation and statistical methodology. To analyze the student interviews, we initiated the development of an annotation guideline to extract key information that is associated with students' behaviors, attitudes, feelings, use of technology and other activities. Statistical analysis was applied to associate the significant categories with students' risk levels to identify key factors which will help with developing action steps to reduce risk. In a future study, we plan to recruit more subjects in order to fully develop the manual annotation which will result in a more standardized and sensitive approach to school violence assessments.

    Cosmetics are one of the most common reasons for hospital referrals with allergic contact dermatitis. Because of the increased use of cosmetics within the population and an increase in allergy cases, monitoring of heavy metals, especially allergen metals, is crucial. The aim of this study was to investigate the concentration of allergen metals, nickel (Ni), cobalt (Co), and chromium (Cr), in the most commonly used cosmetic products including mascara, eyeliner, eye shadow, lipstick, and nail polish. In addition, for safety assessment of cosmetic products, margin of safety of the metals was evaluated. Forty-eight makeup products were purchased randomly from local markets and large cosmetic stores in Istanbul, Turkey, and an atomic absorption spectrometer was used for metal content determination. Risk assessment of the investigated cosmetic products was performed by calculating the systemic exposure dosage (SED) using Scientific Committee on Consumer Safety guideline. According to the results of this investigation in all the samples tested, at least two of the allergen metals, Ni and/or Co and/or Cr were detected. Moreover, 97% of the Ni-detected products, 96% of Cr- and 54% of Co-detected products, contained over 1 μg/g of this metals, which is the suggested ultimate target value for sensitive population and thereby can be considered as the possible allergen. On the basis of the results of this study, SED of the metals was negligible; however, contact dermatitis caused by cosmetics is most probably due to the allergen metal content of the products. In conclusion, to assess the safety of the finished products, postmarketing vigilance and routine monitoring of allergen metals are very important to protect public health.

    2015-12-01

    Poor adherence to pediatric cancer treatment protocols may prevent children and adolescents from realizing the potential benefits of therapy. This paper presents the evidence for a standard of care for supporting medication adherence. Databases were reviewed for articles examining adherence and including children and/or adolescents with cancer. Fourteen articles (i.e., qualitative, quantitative, review, and randomized clinical trials) were evaluated for rigor. There is moderate-quality evidence to support a strong recommendation for adherence to be assessed routinely and monitored throughout the treatment. Integrating the proposed clinical procedures into standard clinical care may improve outcomes for children and adolescents with cancer.

    Full Text Available Due to its economic and nutritional value, the world production of chestnuts is increasing as new stands are being planted in various regions of the world. This work focuses on the relation between weather and annual chestnut production to model the role of weather, to assess the impacts of climate change and to identify appropriate locations for new groves. The exploratory analysis of chestnut production time series and the striking increase of production area have motivated the use for chestnut productivity. A large set of meteorological variables and remote sensing indices were computed and their role on chestnut productivity evaluated with composite and correlation analyses. These results allow for the identification of the variables cluster with a high correlation and impact on chestnut production. Then, different selection methods were used to develop multiple regression models able to explain a considerable fraction of productivity variance: (i a simulation model (R2-value = 87% based on the winter and summer temperature and on spring and summer precipitation variables; and, (ii a model to predict yearly chestnut productivity (R2-value of 63% with five months in advance, combining meteorological variables and NDVI. Goodness of fit statistic, cross validation and residual analysis demonstrate the model's quality, usefulness and consistency of obtained results.

    Due to the interest in the production and trading of yateí (Tetragonisca angustula) honey in the province of Misiones, Argentina, in this work we assessed microbiological and physicochemical parameters in order to contribute to the elaboration of standards for quality control and promote commercialization. Results showed that yateí honey samples had significantly different microbiological and physicochemical characteristics in comparison to established quality standards for Apis mellifera honey. Thus, we observed that values for pH (3.72), glucose (19.01 g/100g) and fructose (23.74 g/100g) were lower than A. mellifera quality standards, while acidity (79.42 meq/kg), moisture (24%), and mould and yeast count (MY) (3.02 log CFU/g) were higher. The acid content was correlated with glucose (R2=0.75) and fructose (R2=0.68) content, and also with mould and yeast counts (R2=0.45) to a lesser extent. The incidence of microorganisms in yateí honey samples reached 42.85% and 39% for Clostridium sulfite-reducers and Bacillus spp., respectively. No C. botulinum or B. cereus cells were detected. Enterococcus spp. and Staphylococcus spp. incidence was similar (ca. 7.14%), whereas Escherichia coli and Salmonella spp. were not detected. We conclude that the microbiological and physicochemical properties of yateí honey are different from those of A. mellifera honey; hence, different quality standards could be implemented to promote its commercialization.

    Full Text Available Sustainable use of natural resources in the production of construction materials has become a necessity both in Europe and Turkey. Construction products in Europe should have European Conformity (CE and Environmental Product Declaration (EPD, an independently verified and registered document in line with the European standard EN 15804. An EPD certificate can be created by performing a Life Cycle Assessment (LCA study. In this particular work, an LCA study was carried out for a refractory brick production for environmental assessment. In addition to the LCA, the Life Cycle Cost (LCC analysis was also applied for economic assessment. Firstly, a cradle-to-gate LCA was performed for one ton of magnesia spinel refractory brick. The CML IA method included in the licensed SimaPro 8.0.1 software was chosen to calculate impact categories (namely, abiotic depletion, global warming potential, acidification potential, eutrophication potential, human toxicity, ecotoxicity, ozone depletion potential, and photochemical oxidation potential. The LCC analysis was performed by developing a cost model for internal and external cost categories within the software. The results were supported by a sensitivity analysis. According to the results, the production of raw materials and the firing process in the magnesia spinel brick production were found to have several negative effects on the environment and were costly.

    Full Text Available The goal of this work is to inter-compare a number of global land surface emissivity products over various land-cover conditions to assess their consistency. Ultimately, the discrepancies between the studied emissivity products will help interpreting the divergences among numerical weather prediction models in which land emissivity is a key surface boundary parameter. The intercompared retrieved land emissivity products were generated over five-year period (2003–2007 using observations from the Advanced Microwave Scanning Radiometer – Earth Observing System (AMSR-E, Special Sensor Microwave Imager (SSM/I, The Tropical Rainfall Measuring Mission (TRMM Microwave Imager (TMI and Windsat. First, all products were reprocessed in the same projection and spatial resolution as they were generated from sensors with various configurations. Then, the mean value and standard deviations of monthly emissivity values were calculated for each product to assess the spatial distribution of the consistencies/inconsistencies among the products across the globe. The emissivity values from four products were also compared to soil moisture estimates and satellite-based vegetation index to assess their sensitivities to the changes in land surface conditions. Results show that systematic differences among products exist and variation of emissivities at each product has similar frequency dependency at any land cover type. Monthly means of emissivity values from AMSR-E in the vertical and horizontal polarizations seem to be systematically lower across various land cover condition which may be attributed to the 1.30 a.m./p.m. overpass time of the sensor and possibly a residual skin temperature effect in the product. The standard deviation of the analysed products was the lowest (less than 0.01 in rain forest regions for all products and the highest in northern latitudes, above 0.04 for AMSR-E and SSM/I and around 0.03 for WindSat.

    strategy is most successful with less number of VAV zones and proper control of AHU supply air temperature. One recommendation is to recommission heating or cooling airflow setpoints so the VAV zone damper is not left wide open when under the control of the TTR strategy. Static pressure control was as expected on 3 of the 5 sites studied. The TTR strategy was able to respond to building loads while minimizing or eliminating issues with static pressure oscillation. However, the TTR strategy displayed numerous instances of frequent static pressure oscillation, especially at sites that had difficulty in controlling zone temperatures from inactive boiler or chiller service. The results from the TTR and TR comparison showed that temperature control with a radiant in-floor heating system was difficult for both static pressure reset strategies studied. In future studies, boiler and chiller data including: operation, temperature, setpoints, etc. should be trended. A comparison of the TTR strategy with fixed supply air temperature and an outside air based supply air temperature reset strategy would be insightful. Parameters such as the TM and RP rates, Step Timer and damper position thresholds could be refined to maintain a quick response to changing building loads. Lastly, as industries and professional standards progress with improved building standards, the focus of future studies should shift from comparing against fixed static pressure strategies to existing static pressure reset strategies in not only fan energy savings, but whole building energy savings as well.

    2016-07-01

    Growing global consumer concern over food safety in the fresh produce industry requires producers to implement necessary quality assurance systems. Varying effectiveness has been noted in how countries and food companies interpret and implement food safety standards. A diagnostic instrument (DI) for global fresh produce industries was developed to measure the compliancy of companies with implemented food safety standards. The DI is made up of indicators and descriptive grids for context factors and control and assurance activities to measure food safety output. The instrument can be used in primary production to assess food safety performance. This study applied the DI to measure food safety standard compliancy of mushroom farming in South Africa. Ten farms representing almost half of the industry farms and more than 80% of production were independently assessed for their horticultural safety management system (HSMS) compliance via in-depth interviews with each farm's quality assurance personnel. The data were processed using Microsoft Office Excel 2010 and are represented in frequency tables. The diagnosis revealed that the mushroom farming industry had an average food safety output. The farms were implementing an average-toadvanced HSMS and operating in a medium-risk context. Insufficient performance areas in HSMSs included inadequate hazard analysis and analysis of control points, low specificity of pesticide assessment, and inadequate control of suppliers and incoming materials. Recommendations to the industry and current shortcomings are suggested for realization of an improved industry-wide food safety assurance system.

    Mixtures of known proteins have been very useful in the assessment and validation of methods for high-throughput (HTP) MS (MS/MS) proteomics experiments. However, these test mixtures have generally consisted of few proteins at near equal concentration or of a single protein at varied concentrations. Such mixtures are too simple to effectively assess the validity of error rates for protein identification and differential expression in HTP MS/MS studies. This work aimed at overcoming these limitations and simulating studies of complex biological samples. We introduced a pair of 54-protein standard mixtures of variable concentrations with up to a 1000-fold dynamic range in concentration and up to ten-fold expression ratios with additional negative controls (infinite expression ratios). These test mixtures comprised 16 off-the-shelf Sigma-Aldrich proteins and 38 Shewanella oneidensis proteins produced in-house. The standard proteins were systematically distributed into three main concentration groups (high, medium, and low) and then the concentrations were varied differently for each mixture within the groups to generate different expression ratios. The mixtures were analyzed with both low mass accuracy LCQ and high mass accuracy FT-LTQ instruments. In addition, these 54 standard proteins closely follow the molecular weight distributions of both bacterial and human proteomes. As a result, these new standard mixtures allow for a much more realistic assessment of approaches for protein identification and label-free differential expression than previous mixtures. Finally, methodology and experimental design developed in this work can be readily applied in future to development of more complex standard mixtures for HTP proteomics studies.

  6. Life Cycle Assessment of Willow Production; Livscykelanalys av Salixproduktion

    2006-05-15

    The aim of this study is to make a life cycle assessment (LCA) of willow production (Salix) based on current cultivation practices and commercial clones. The purpose is to describe the environmental impact of the different phases in the production system and identify phases which have a significant impact on the total life cycle emissions. The production of willow is assumed to take place in southern Sweden on good agricultural soils. The results show that the production of willow is an energy efficient biomass production system which gives 20 times more energy in the form of biomass than the required energy input. In comparison with cultivation of annual energy crops, such as rape and wheat, the energy balance (energy output/energy input) of willow production is more than 3 times higher. The emissions of greenhouse gases and pollutants leading to eutrophication, acidification and creation of photochemical oxidants are often 2 to 4 times lower in willow production. The phase in willow production which requires the highest energy input, some 50 %, is fertilisation. Fertilisation also causes the highest emissions, often between 50 to 80 %, of the total life cycle emissions. Thereafter comes harvesting, with about 30 % of the energy input and 7 to 15 % of the emissions (except for the emissions leading to the creation of photochemical oxidants, some 50%), followed by establishment and transportation which normally contribute to 2 to 10 % of the total life cycle emissions. A measure to efficiently reduce the life cycle emissions of willow production is through a higher efficiency in the production of commercial fertilisers including flue-gas cleaning, leading to reduced emissions, particularly of nitrous oxide (N{sub 2}O). Other alternatives are utilising nutrient-rich organic waste products, such as sewage sludge and municipal waste water as fertilisers, which are already in practice in some willow cultivations today.

    Wheelchairs are, for users, a primary means of mobility and an important means of performing activities of daily living. A common, accepted vocabulary is required to support and foster evidence-based practice and communication amongst professionals and with users. The international standard for wheelchair vocabulary, ISO 7176-26:2007, specifies terms and definitions with the purpose of eliminating confusion from the duplication or inappropriate use of terms. The aim of this study was to assess its impact and, based on that assessment, critically appraise the standard. Two databases were searched returning 189 and 283 unique articles with wheelchair in the title published between 2004-2006 and 2009-2011 respectively. Compliance, based on title and abstract usage, was poor, ranging from 0 to 50% correct usage, with no significant difference between pre- and post-publication. A review of prescription forms found only 9% correct usage. A survey of NHS wheelchair managers found that only 30% were positive that they had a copy despite 67% agreeing that the standard is important. The ISO wheelchair vocabulary standard was found not to be achieving its stated purpose. It is recommended that it be revised taking into account the findings of this study including the need for targeted dissemination and increased awareness.

    Full Text Available This paper identifies trends in secondary school accounting participation and achievement during the firstfive years of the full implementation of the National Certificate of Educational Achievement (NCEA in NewZealand schools. NCEA marks a shift from a norm-referenced assessment regime to standards-basedassessment. Literature suggests that standards-based assessment increases the academic performance ofminority ethnic groups (such as Maori and Pacific Island students, and low socio-economic status (SESstudents. The author pays particular attention to these groups and his analysis reveals some interestingresults: in accounting, the NCEA has not met expectations for these students. From 2004 to 2008, thenumber of low SES accounting students has dropped, as has the number of accounting standards entered andthe rates of achievement. Likewise, there has been no significant improvement in the academic performanceof Maori students taking accounting standards, while Pacific Island students have experienced a significantdecrease in achievement. The author also discusses how studying high school accounting impacts on tertiarylevel study and offers some future implications of this research.

  9. Environmental implications of accelerated gasohol production: preliminary assessment

    Energy Technology Data Exchange (ETDEWEB)

    1980-01-01

    This report assesses the environmental impacts of increasing US production of fuel ethanol by 330 million gallons per year in the 1980 to 1981 time frame in order to substitute gasohol for 10% of the unleaded gasoline consumed in the United States. Alternate biomass feedstocks are examined and corn is selected as the most logical feedstock, based on its availability and cost. Three corn conversion processes that could be used to attain the desired 1980 to 1981 production are identified; fermentation plants that use a feedstock of starch and wastes from an adjacent corn refining plants are found to have environmental and economic advantages. No insurmountable environmental problems can be achieved using current technology; the capital and operating costs of this control are estimated. If ethanol production is increased substantially after 1981, the environmentally acceptable use or disposal of stillage, a liquid by-product of fermentation, could become a serious problem.

    Because assessment of Durum wheat semolina purity by standard ash-test has been widely criticized, we attempted to characterize products of a semolina mill by spectrofluorometry and fluorescence imaging. A collection of milled wheat products ranging from very pure semolina to brans were chosen for this study. Multidimensional statistical analyses (Principal component analyses) were applied to the spectral and image data. Maps showing a classification of the products according to purity were obtained without biochemical calibration. Principal component regression was applied to the data in order to test the relationship of aleurone fluorescence to ash content. Both spectrofluorometry and fluorescence imaging gave similar results with good determination coefficients (r2 equals 0.97 and 0.92) for the study of a single wheat variety. Products obtained from different wheat varieties were more difficult to compare.

    Over the last decennia, the use of Geographic Information (GI) has gained importance, in public as well as in private sector. But even if many spatial data and related information exist, data sets are scattered over many organizations and departments. In practice it remains difficult to find the spatial data sets needed, and to access, obtain and prepare them for using in applications. Therefore Spatial Data Infrastructures (SDI) haven been developed to enhance the access, the use and sharing of GI. SDIs consist of a set of technological and non-technological components to reach this goal. Since the nineties many SDI initiatives saw light. Ultimately, all these initiatives aim to enhance the flow of spatial data between organizations (users as well as producers) involved in intra- and inter-organizational and even cross-country business processes. However, the flow of information and its re-use in different business processes requires technical and semantic interoperability: the first should guarantee that system components can interoperate and use the data, while the second should guarantee that data content is understood by all users in the same way. GI-standards within the SDI are necessary to make this happen. However, it is not known if this is realized in practice. Therefore the objective of the research is to develop a quantitative framework to assess the impact of GI-standards on the performance of business processes. For that purpose, indicators are defined and tested in several cases throughout Europe. The proposed research will build upon previous work carried out in the SPATIALIST project. It analyzed the impact of different technological and non-technological factors on the SDI-performance of business processes (Dessers et al., 2011). The current research aims to apply quantitative performance measurement techniques - which are frequently used to measure performance of production processes (Anupindi et al., 2005).

    Full Text Available This paper presents the technological process of manufacture of a shoe for women in IL system in order to establish the time and the production norm in the processing-sewing procedure. The sequence of operations is presented in a case study that analyzed how can be obtained the upper assembly of a footwear product that later becomes integral part into the finished product. Drawing up the technological process is done considering both the manual operations and the manual-mechanical operations for processing and assembling the parts that make the whole upper assembly by gluing the parts, by seaming and securing the joints. The type of equipment chosen to carry out operations is influencing through its productivity the necessary material calculated and hence the labour force required. The amount of time consists of time needed for preparation-finishing time, operative time, time of working place service and time of regulated interruptions. These periods of times were determined basically by timing assistance of the manufacturing process throughout its development. Production norm is calculated on the basis of the standard time, taking into account that it represents the amount of products manufactured in a work shift In order to improve the process by reducing the time of production and the number of workers engaged we are considering the automation of the manufacturing process by using modern methods using laser cutting or cutting under running water, automatic sewing machines, strip conveyor belts with pace imposed etc.

    2014-03-01

    Full Text Available Pomegranate (Punica granatum L. is a fruit with a long medicinal history, especially due to its phenolic compounds content, such as the anthocyanins, which are reported as one of the most important natural antioxidants. The analysis of the anthocyanins by high performance liquid chromatography (HPLC can be considered as an important tool to evaluate the quality of pomegranate juice. For research laboratories the major challenge in using HPLC for quantitative analyses is the acquisition of high purity analytical standards, since these are expensive and in some cases not even commercially available. The aim of this study was to obtain analytical standards for the qualitative and quantitative analysis of the anthocyanins from pomegranate. Five vegetable matrices (pomegranate flower, jambolan, jabuticaba, blackberry and strawberry fruits were used to isolate each of the six anthocyanins present in pomegranate fruit, using an analytical HPLC scale with non-destructive detection, it being possible to subsequently use them as analytical standards. Furthermore, their identities were confirmed by high resolution mass spectrometry. The proposed procedure showed that it is possible to obtain analytical standards of anthocyanins with a high purity grade (98.0 to 99.9% from natural sources, which was proved to be an economic strategy for the production of standards by laboratories according to their research requirements.

    The U.S. federal government regulates the reliability of bulk power systems, while the reliability of power distribution systems is regulated at a state level. In this article, we review the history of regulating electric service reliability and study the existing reliability metrics, indices, and standards for power transmission and distribution networks. We assess the foundations of the reliability standards and metrics, discuss how they are applied to outages caused by large exogenous disturbances such as natural disasters, and investigate whether the standards adequately internalize the impacts of these events. Our reflections shed light on how existing standards conceptualize reliability, question the basis for treating large-scale hazard-induced outages differently from normal daily outages, and discuss whether this conceptualization maps well onto customer expectations. We show that the risk indices for transmission systems used in regulating power system reliability do not adequately capture the risks that transmission systems are prone to, particularly when it comes to low-probability high-impact events. We also point out several shortcomings associated with the way in which regulators require utilities to calculate and report distribution system reliability indices. We offer several recommendations for improving the conceptualization of reliability metrics and standards. We conclude that while the approaches taken in reliability standards have made considerable advances in enhancing the reliability of power systems and may be logical from a utility perspective during normal operation, existing standards do not provide a sufficient incentive structure for the utilities to adequately ensure high levels of reliability for end-users, particularly during large-scale events.

    This paper analyzes the way risk management measures (RMMs) for consumer products have been used to date in authority and industry risk assessments. A working concept for consumer product RMMs is developed, aimed at controlling, limiting or avoiding exposures, and helping to insure the safe use (or handling) of a substance as part of a consumer product. Particular focus is placed on new requirements introduced by REACH (registration, evaluation, and authorization of chemicals). A RMMs categorization approach is also developed, dividing consumer product RMMs into those that are product integrated and those that are communicated to consumers. For each of these categories, RMMs for normal use, accidental use or misuse need to be distinguished. The level of detail for documenting, assessing and communicating RMMs across supply chains can vary, depending on the type of the assessment (tiered approach). Information on RMMs was collected from published sources to demonstrate that a taxonomical approach using standard descriptors for RMMs libraries is needed for effective information exchange across supply chains.

    Full Text Available “Global Learning” with shared learning contents, resources, activities and goals is one of the contributions of Globalization. With the capability to use new Information and Communication Technologies (ICT it is a bit easier to have a technology based learning systems that enable learners to share the learning resources and possibilities. As a result many Learning Management Systems (LMS were developed with divers of platforms and approaches. Consequently, sharing learning resources and components has become a major challenge. E-assessment as a primary activity of any LMS is facing the same challenges and problems. In order to stand on this challenge people in the field of technology enhanced learning have recommended that LMS should conform to specific standards. This paper discuses this challenge, the consequences and limitations of standards in the modern learning settings. Moreover, it shows a service oriented framework for assessment which aims to make the e-assessment systems flexible and also to initiate the term of “Global Learning Assessment” with the possibility of sharing the e-assessment system components.

    Since 1976, the Industrial Assessment Centers (IACs), administered by the US Department of Energy, have supported small and medium-sized American manufacturers to reduce energy use and increase their productivity and competitiveness. The 24 IACs, located at premier engineering universities around the country (see below), send faculty and engineering students to local small and medium-sized manufacturers to provide no-cost assessments of energy use, process performance and waste and water flows. Under the direction of experienced professors, IAC engineering students analyze the manufacturer’s facilities, energy bills and energy, waste and water systems, including compressed air, motors/pumps, lighting, process heat and steam. The IACs then follow up with written energy-saving and productivity improvement recommendations, with estimates of related costs and payback periods.

    Drought assessment is essential for coping with frequent droughts nowadays. Owing to the large spatio-temporal variations in hydrometeorology in most regions in China, it is very necessary to use a physically-based hydrological model to produce rational spatial and temporal distributions of hydro-meteorological variables for drought assessment. In this study, the large-scale distributed hydrological model Variable Infiltration Capacity (VIC) was coupled with a modified standardized runoff index (SRI) for drought assessment in the Weihe River basin, northwest China. The result indicates that the coupled model is capable of reasonably reproducing the spatial distribution of drought occurrence. It reflected the spatial heterogeneity of regional drought and improved the physical mechanism of SRI. This model also has potential for drought forecasting, early warning and mitigation, given that accurate meteorological forcing data are available.

  5. A New Classification Analysis of Customer Requirement Information Based on Quantitative Standardization for Product Configuration

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Traditional methods used for the classification of customer requirement information are typically based on specific indicators, hierarchical structures, and data formats and involve a qualitative analysis in terms of stationary patterns. Because these methods neither consider the scalability of classification results nor do they regard subsequent application to product configuration, their classification becomes an isolated operation. However, the transformation of customer requirement information into quantifiable values would lead to a dynamic classification according to specific conditions and would enable an association with product configuration in an enterprise. This paper introduces a classification analysis based on quantitative standardization, which focuses on (i expressing customer requirement information mathematically and (ii classifying customer requirement information for product configuration purposes. Our classification analysis treated customer requirement information as follows: first, it was transformed into standardized values using mathematics, subsequent to which it was classified through calculating the dissimilarity with general customer requirement information related to the product family. Finally, a case study was used to demonstrate and validate the feasibility and effectiveness of the classification analysis.

    NOAA's National Weather Service (NWS) Climate Services Division (CSD) is developing a comprehensive climate user requirements process with the ultimate goal of producing climate services that meet the needs of NWS climate information users. An important part of this effort includes engaging users through periodical surveys conducted by the Claes Fornell International (CFI) Group using the American Customer Satisfaction Index (ACSI). The CFI Group conducted a Climate Services Satisfaction (CSS) Survey in May of 2009 to measure customer satisfaction with current products and services and to gain insight on areas for improvement. The CSS Survey rates customer satisfaction on a range of NWS climate services data and products, including Climate Prediction Center (CPC) outlooks, drought monitoring, and ENSO monitoring and forecasts, as well as NWS local climate data services. In addition, the survey assesses the users of the products to give the NWS insight into its climate customer base. The survey also addresses specific topics such as NWS forecast category names, probabilistic nature of climate products, and interpretation issues. The survey results identify user requirements for improving existing NWS climate services and introducing new ones. CSD will merge the survey recommendations with available scientific methodologies and operational capabilities to develop requirements for improved climate products and services. An overview of the 2009 survey results will be presented, such as users' satisfaction with the accuracy, reliability, display and functionality of products and services.

    This study addresses the analysis of the consistency among global precipitation products over arid regions. First, precipitation products were examined against in situ observations from the UAE network. Then, the consistency among the different products was assessed regionally over the Arabian Peninsula and the Sahara Desert. Four distinct independently-derived precipitation products, namely, Global Precipitation Climate Center (GPCC), Willmott-Matsuura 2001 (WM), Tropical Rainfall Measurement Mission (TRMM), and CPC Morphing (CMORPH) were examined. Over the UAE, in situ monthly observations from 6 stations over a time period of 11 years, from 2000 to 2010 inclusive, were used. The correlation with in situ observations, Root Mean Square Error (RMSE), and Relative Bias (rBIAS) were calculated to evaluate the precipitation products. The lowest areal averaged RMSE over all stations, ranging from 3.82mm to 9.98mm, was obtained with the GPCC indicating a higher agreement with in situ observations. The average RMSE of GPCC over the country was 6.18mm. However, the highest areal averaged RMSE, ranging from 9.44 to 19.52mm, was obtained with the WM product with average of 13.57mm. The results showed an overestimation of the observed rainfall values across all products with overall average of 42%. CMORPH product was found to be the most inconsistent products spatially across the UAE with rBIAS ranging from -47% in Al Ain to 372% in Dubai. The correlation with in situ observations was found to be higher with GPCC product ranging from 0.8450 to 0.9494. TRMM was second with an average of 0.8413, ranging from 0.7098 to 0.9248. Furthermore, Mean Relative Difference (MRD) was calculated to investigate the precision among the precipitation products. CMORPH was found to be inconsistent spatially being the lowest estimator for four stations (Adu Dhabi, Al Ain, Sharjah, Ras Al Khaimah) whereas being the highest estimator for the rest two stations (Dubai and Fujairah).

    VTT Technical Research Centre of Finland organised a Symposium 'Life Cycle Assessment of Products and Technologies' on the 6th of October, 2009. The Symposium gave a good overview of methods, tools and applications of Life Cycle Assessment developed and utilised in several technology fields of VTT. The 12 Symposium papers deal with recent LCA studies on products and technologies. The scope ranges from beverage cups to urban planning, from inventory databases to rating systems. Topical issues relating to climate change concern biorefineries and the overall impacts of the utilisation of biomass. The calculation of carbon footprints is also introduced through paper products and magazines. One example of LCA tools developed at VTT addresses cement manufacturing. VTT's transport emission database, LIPASTO, was introduced in detail. The use of LCA methods and life cycle thinking is described in various contexts: product development in relation to precision instruments; selection of materials and work processes in relation to sediment remediation project; and procedures of sustainability rating through VTT's office building Digitalo. The Climate Bonus project presented a demonstrated ICT support that informs about the greenhouse gas emissions and carbon footprints of households. (orig.)

  13. ASSESSMENT OF COMBINED STRAW PULP AND ENERGY PRODUCTION

    Directory of Open Access Journals (Sweden)

    Anja Paula Maria Leponiemi

    2011-04-01

    Full Text Available The aim of this study was to evaluate the potential of a new, straw-based fibre manufacturing technology integrated to bioenergy and biofuels production. The process is based on a novel hot water treatment and subsequent mechanical refining, both of which are performed at a high temperature. Soda process, ethanol production, and chemical defibration based on hot water treatment and subsequent alkaline peroxide bleaching were selected as references. The idea is to utilise the fibre fraction for packaging and the dissolved solids and the formed fines for energy. The investment costs of this process are significantly lower than those of a soda process. Additionally, a chemicals recovery process is unnecessary. Furthermore, the process offers an attractive alternative for biogas production. However, the assessment showed that the process could only be economical in some terms. Subsidies for investment would probably be needed to promote the acceptance of this environmentally safe process.

    Many gene therapy medicinal products and also some vaccines consist of, or contain, genetically modified organisms (GMOs), which require specific consideration in the environmental risk assessment (ERA) before marketing authorisation or clinical trial applications. The ERA is performed in order to identify the potential risks for public health and the environment, which may arise due to the clinical use of these medicinal products. If such environmental risks are identified and considered as not acceptable, the ERA should go on to propose appropriate risk management strategies capable to reduce these risks. This article will provide an overview of the legal basis and requirements for the ERA of GMO-containing medicinal products in the context of marketing authorisation in the EU and clinical trials in Germany. Furthermore, the scientific principles and methodology that generally need to be followed when preparing an ERA for GMOs are discussed.

  16. Assessing children’s competence to consent in research by a standardized tool: a validity study

    2012-09-01

    Full Text Available Abstract Background Currently over 50% of drugs prescribed to children have not been evaluated properly for use in their age group. One key reason why children have been excluded from clinical trials is that they are not considered able to exercise meaningful autonomy over the decision to participate. Dutch law states that competence to consent can be presumed present at the age of 12 and above; however, in pediatric practice children’s competence is not that clearly presented and the transition from assent to active consent is gradual. A gold standard for competence assessment in children does not exist. In this article we describe a study protocol on the development of a standardized tool for assessing competence to consent in research in children and adolescents. Methods/design In this study we modified the MacCAT-CR, the best evaluated competence assessment tool for adults, for use in children and adolescents. We will administer the tool prospectively to a cohort of pediatric patients from 6 to18 years during the selection stages of ongoing clinical trials. The outcomes of the MacCAT-CR interviews will be compared to a reference standard, established by the judgments of clinical investigators, and an expert panel consisting of child psychiatrists, child psychologists and medical ethicists. The reliability, criterion-related validity and reproducibility of the tool will be determined. As MacCAT-CR is a multi-item scale consisting of 13 items, power was justified at 130–190 subjects, providing a minimum of 10–15 observations per item. MacCAT-CR outcomes will be correlated with age, life experience, IQ, ethnicity, socio-economic status and competence judgment of the parent(s. It is anticipated that 160 participants will be recruited over 2 years to complete enrollment. Discussion A validity study on an assessment tool of competence to consent is strongly needed in research practice, particularly in the child and adolescent population. In

    Background: Benchmark dose (BMD) modeling computes the dose associated with a prespecified response level. While offering advantages over traditional points of departure (PODs), such as no-observed-adverse-effect-levels (NOAELs), BMD methods have lacked consistency and transparency in application, interpretation, and reporting in human health assessments of chemicals. Objectives: We aimed to apply a standardized process for conducting BMD modeling to reduce inconsistencies in model fitting and selection. Methods: We evaluated 880 dose–response data sets for 352 environmental chemicals with existing human health assessments. We calculated benchmark doses and their lower limits [10% extra risk, or change in the mean equal to 1 SD (BMD/L10/1SD)] for each chemical in a standardized way with prespecified criteria for model fit acceptance. We identified study design features associated with acceptable model fits. Results: We derived values for 255 (72%) of the chemicals. Batch-calculated BMD/L10/1SD values were significantly and highly correlated (R2 of 0.95 and 0.83, respectively, n = 42) with PODs previously used in human health assessments, with values similar to reported NOAELs. Specifically, the median ratio of BMDs10/1SD:NOAELs was 1.96, and the median ratio of BMDLs10/1SD:NOAELs was 0.89. We also observed a significant trend of increasing model viability with increasing number of dose groups. Conclusions: BMD/L10/1SD values can be calculated in a standardized way for use in health assessments on a large number of chemicals and critical effects. This facilitates the exploration of health effects across multiple studies of a given chemical or, when chemicals need to be compared, providing greater transparency and efficiency than current approaches.

    2013-05-01

    Digital products of fundamental geographic information are the main components of Digital China Geo-spatial Framework (DCGSF for short). More and more mass data were produced and distributed to various users by different agencies and organizations with continuous implementation of fundamental surveying and mapping activities and various specified projects within national Administration of Surveying, Mapping & Geoinformation. Therefore, what about the description and quality assessment used for these products will directly effect the acquisition, delivery, share, and application of data. A quality model, by which quality is assessed through 3 levels of classification of quality elements, quality subelements, and check items, was built in this paper based on ISO 19113 and ISO 19114 so that to make the quality of digital products of fundamental geographic information to be assessed reasonably, and to make the quality assessment tools to be operable in practice. Quality assessment methods respectively for each of quality elements, quality subelements, and check items are presented. Fundamental data of Digital Line Graphs, Digital Elevation Models, Digital Orthophoto Maps, and Digital Raster Maps at the scale of 1:50,000 in DCGSF were used as examples to determine the quality of 9 quality elements, 24 quality subelements, and 68 check items considering the contents and the requirements of various users for these data, as well as the practical experiences in quality assessment. 300 DLGs selected from national key projects of surveying and mapping engineering were used for testing to validate the operability of the results mentioned in this paper. Random sampling is used, when sampling, for each layer, which is layered based on production unit and level of difficulty. Quality checking and quality assessment, and statistical analysis was done for samples in terms of item product and lot products respectively. The results from this test indicated that quality model and

    Spatial variability in yields and greenhouse gas emissions from soils has been identified as a key source of variability in life cycle assessments (LCAs) of agricultural products such as cellulosic ethanol. This study aims to conduct an LCA of cellulosic ethanol production from switchgrass in a way that captures this spatial variability and tests results for sensitivity to using spatially averaged results. The Environment Policy Integrated Climate (EPIC) model was used to calculate switchgrass yields, greenhouse gas (GHG) emissions, and nitrogen and phosphorus emissions from crop production in southern Wisconsin and Michigan at the watershed scale. These data were combined with cellulosic ethanol production data via ammonia fiber expansion and dilute acid pretreatment methods and region-specific electricity production data into an LCA model of eight ethanol production scenarios. Standard deviations from the spatial mean yields and soil emissions were used to test the sensitivity of net energy ratio, global warming potential intensity, and eutrophication and acidification potential metrics to spatial variability. Substantial variation in the eutrophication potential was also observed when nitrogen and phosphorus emissions from soils were varied. This work illustrates the need for spatially explicit agricultural production data in the LCA of biofuels and other agricultural products.

    Housing systems for laying hens have changed over the years due to increased public concern regarding animal welfare. In terms of sustainability, animal welfare is just one aspect that needs to be considered. Social aspects as well as environmental and economic factors need to be included as well. In this study, we assessed the sustainability of enriched cage, barn, free-range, and organic egg production systems following a predefined protocol. Indicators were selected within the social, environmental, and economic dimensions, after which parameter values and sustainability limits were set for the core indicators in order to quantify sustainability. Uncertainty in the parameter values as well as assigned weights and compensabilities of the indicators influenced the outcome of the sustainability assessment. Using equal weights for the indicators showed that, for the Dutch situation, enriched cage egg production was most sustainable, having the highest score on the environmental dimension, whereas free-range egg production gave the highest score in the social dimension (covering food safety, animal welfare, and human welfare). In the economic dimension both enriched cage egg and organic egg production had the highest sustainability score. When weights were attributed according to stakeholder outputs, individual differences were seen, but the overall scores were comparable to the sustainability scores based on equal weights. The provided method enabled a quantification of sustainability using input from stakeholders to include societal preferences in the overall assessment. Allowing for different weights and compensabilities helps policymakers in communicating with stakeholders involved and provides a weighted decision regarding future housing systems for laying hens.

    Due to the consumption of chicken and chicken products in Turkey at high ratio, trace metal content of chicken and chicken products from Turkey were determined by atomic absorption spectrometry after microwave digestion. The accuracy of the method was confirmed by analysis of standard reference material (NIST SRM 1577b Bovine liver). Trace element content in various parts of chicken samples and chicken products were to be in the range of 0.10-114 microg/g for copper, 0.25-6.09 microg/kg for cadmium, 0.01-0.40 microg/g for lead, 0.10-0.91 microg/g for selenium, 0.05-3.91 microg/g for manganese, 0.06-0.10 microg/g for arsenic, 0.01-0.72 microg/g for chromium, 0.01-2.08 microg/g for nickel, 0.01-0.02 microg/g for cobalt, 0.10-1.90 microg/g for aluminium, 1.21-24.3 microg/g for zinc, 2.91-155 microg/g for iron. The levels of lead in some analyzed chicken products were higher than the recommended legal limits for human consumption.

    Eurima, the European Insulation Manufacturers` Association, has carried through a project on standardisation of a full-scale chamber method for regulation purposes by simulation of building site fibre emission from mineral wool products during installation. For some years five Eurima member companies have worked with individual full-scale chamber measurements, using different chamber sizes and installation procedures. Due to different test conditions, the previous test results obtained are not comparable and thus form an unreliable basis for determination of a standard method. The chamber size and several other parameters seem to influence the fibre concentration. During the project in question all relevant parameters, which are considered to have a measurable impact on the fibre concentration, have been examined, and suitable standard test conditions have been defined according to the test results.

    We study the impact of dimension-six operators of the standard model effective field theory relevant for vector-boson fusion and associated Higgs boson production at the LHC. We present predictions at the next-to-leading order accuracy in QCD that include matching to parton showers and that rely on fully automated simulations. We show the importance of the subsequent reduction of the theoretical uncertainties in improving the possible discrimination between effective field theory and standard model results, and we demonstrate that the range of the Wilson coefficient values allowed by a global fit to LEP and LHC Run I data can be further constrained by LHC Run II future results.

    Araujo, Victor Kraemer Wermelinger Sancho; Hamacher, Silvio; Scavarda, Luiz Felipe

    2010-06-01

    Waste frying oils (WFO) can be a good source for the production of biodiesel because this raw material is not part of the food chain, is low cost and can be used in a way that resolves environmental problems (i.e. WFO is no longer thrown into the sewage network). The goal of this article is to propose a method to evaluate the costs of biodiesel production from WFO to develop an economic assessment of this alternative. This method embraces a logistics perspective, as the cost of collection of oil from commercial producers and its delivery to biodiesel depots or plants can be relevant and is an issue that has been little explored in the academic literature. To determine the logistics cost, a mathematical programming model is proposed to solve the vehicle routing problem (VRP), which was applied in an important urban center in Brazil (Rio de Janeiro), a relevant and potential center for biodiesel production and consumption. Eighty-one biodiesel cost scenarios were compared with information on the commercialization of biodiesel in Brazil. The results obtained demonstrate the economic viability of biodiesel production from WFO in the urban center studied and the relevance of logistics in the total biodiesel production cost.

    Full Text Available Abstract Background Previously published studies have reported that up to 43% of patients with disorders of consciousness are erroneously assigned a diagnosis of vegetative state (VS. However, no recent studies have investigated the accuracy of this grave clinical diagnosis. In this study, we compared consensus-based diagnoses of VS and MCS to those based on a well-established standardized neurobehavioral rating scale, the JFK Coma Recovery Scale-Revised (CRS-R. Methods We prospectively followed 103 patients (55 ± 19 years with mixed etiologies and compared the clinical consensus diagnosis provided by the physician on the basis of the medical staff's daily observations to diagnoses derived from CRS-R assessments performed by research staff. All patients were assigned a diagnosis of 'VS', 'MCS' or 'uncertain diagnosis.' Results Of the 44 patients diagnosed with VS based on the clinical consensus of the medical team, 18 (41% were found to be in MCS following standardized assessment with the CRS-R. In the 41 patients with a consensus diagnosis of MCS, 4 (10% had emerged from MCS, according to the CRS-R. We also found that the majority of patients assigned an uncertain diagnosis by clinical consensus (89% were in MCS based on CRS-R findings. Conclusion Despite the importance of diagnostic accuracy, the rate of misdiagnosis of VS has not substantially changed in the past 15 years. Standardized neurobehavioral assessment is a more sensitive means of establishing differential diagnosis in patients with disorders of consciousness when compared to diagnoses determined by clinical consensus.

    In this introduction to the concept of life cycle sustainability assessment (LCSA), we acknowledge the foundations laid by previous works and initiatives. One such initiative has been the ISO 14040 series (Environmental management -- Life cycle assessment -- Principles and framework), which in addition to the ISO 26000: Social Responsibility Guidance Standard, and the contribution of a number of international initiatives (Appendix A) have been essential for the development of this publication. The life cycle of a product involves flows of material, energy and money. Nonetheless, the picture is not complete unless we look also at the production and consumption impacts on all actors along the 'value chain' -- workers, local communities, consumers and society itself. Different life cycle assessment techniques allow individuals and enterprises to assess the impact of their purchasing decisions and production methods along different aspects of this value chain. An (Environmental) life cycle assessment (LCA) looks at potential impacts to the environment as a result of the extraction of resources, transportation, production, use, recycling and discarding of products; life cycle costing (LCC) is used to assess the cost implications of this life cycle; and social life cycle assessment (S-LCA) examines the social consequences. However, in order to get the 'whole picture', it is vital to extend current life cycle thinking to encompass all three pillars of sustainability: (i) environmental, (ii) economic and (iii) social. This means carrying out an assessment based on environmental, economic and social issues -- by conducting an overarching life cycle sustainability assessment (LCSA). This publication shows how all three techniques -- which all share similar methodological frameworks and aims -- can be combined to make the move towards an overarching LCSA possible. Because it is holistic, systemic and rigorous, (environmental) LCA is the preferred technique

The use of standard metadata for provenance for data products in the ESR will enable the transparency, and ultimately reproducibility, endorsed in the recent NOAA Information Quality Guidelines. Semantically enabling not only the provenance but also the data products will yield a better understanding of the connected web of relationships between marine ecosystem and ocean health assessments conducted by different stakeholder groups.

    2007-09-01

    Possible cleaner production (CP) opportunities for a milk processing facility were examined in this study. The CP concept and its key tools of implementation were used to assess the potential CP opportunities in the facility studied. The general production process and its resulting environmental loads were investigated by taking possible CP opportunities as the basis of study. The methodology developed for CP opportunity assessment in the milk processing facility covered two major steps: preparation of checklists to assist auditing and CP opportunity assessment, and implementation of the mass-balance analysis. For mass-balance analysis, measurements and experimental analysis of the mass flows were utilized to determine the inputs and outputs. Prepared checklists were utilized to determine waste reduction options that could be implemented. Selected opportunities were evaluated considering their environmental benefits and economic feasibility. The results of the study indicated that 50% of the service water used, 9.3% of the current wastewater (WW) discharge, 65.36% of the chemical use and the discharge of 181.9 kg/day of chemical oxygen demand (COD) and 20.7 kg/day of total suspended solids (TSS) could be eliminated and 19.6% of the service water used could be recycled/reused.

    Production of top quark pairs in association with heavy Standard Model bosons or with heavy flavour quark-pairs is important both as a signal and a background in several ATLAS analyses. Strong constraints on such processes cannot at present be obtained from data, and therefore their modeling by Monte Carlo simulation as well as the associated uncertainties are important. This poster documents the Monte Carlo samples currently being used in ATLAS for the ttH and ttV (V=W,Z vector bosons) and tt+bottom and charm quark pairs processes for sqrt(s)=13 TeV proton-proton collisions.

    According to the recommendations of the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Neurocognition Committee, one of the desired characteristics of a cognitive battery for assessing cognition in schizophrenia studies and clinical trials is the availability of normative data. This report describes normative data collected on the Brief Assessment of Cognition in Schizophrenia (BACS) from 404 healthy controls with demographic characteristics matching the 2005 United States Census of English-speakers. The six test measures demonstrated the expected pattern of correlations with age, gender, and education. Individual test scores were converted into standardized (T and z) scores and composite scores that were corrected for age and gender. An education-correction factor was calculated and recommended only for non-schizophrenia patients. Eight different verbal memory tests were found to have equivalent levels of difficulty.

    2016-02-01

    Full Text Available Purpose: Among the methods of comprehensive analysis for a product or an enterprise, there exist defects and deficiencies in traditional standard cost analyses and life cycle assessment methods. For example, some methods only emphasize one dimension (such as economic or environmental factors while neglecting other relevant dimensions. This paper builds a factor analysis model of resource value flow, based on full life cycle assessment and eco-design theory, in order to expose the relevant internal logic between these two factors. Design/methodology/approach: The model considers the efficient multiplication of resources, economic efficiency, and environmental efficiency as its core objectives. The model studies the status of resource value flow during the entire life cycle of a product, and gives an in-depth analysis on the mutual logical relationship of product performance, value, resource consumption, and environmental load to reveal the symptoms and potentials in different dimensions. Originality/value: This provides comprehensive, accurate and timely decision-making information for enterprise managers regarding product eco-design, as well as production and management activities. To conclude, it verifies the availability of this evaluation and analysis model using a Chinese SUV manufacturer as an example.

    Antibodies made in large animals are integral to many biomedical research endeavors. Domesticated herd animals like goats, sheep, donkeys, horses and camelids all offer distinct advantages in antibody production. However, their cost of use is often prohibitive, especially where poor antigen response is commonplace; choosing a non-responsive animal can set a research program back or even prevent experiments from moving forward entirely. Over the course of production of antibodies from llamas, we found that some animals consistently produced a higher humoral antibody response than others, even to highly divergent antigens, as well as to their standard vaccines. Based on our initial data, we propose that these "high level responders" could be pre-selected by checking antibody titers against common vaccines given to domestic farm animals. Thus, time and money can be saved by reducing the chances of getting poor responding animals and minimizing the use of superfluous animals.

    Full Text Available Reclamation of spent moulding and core sands has been defined as a treatment of used moulding refractory materials, enabling a recoveryof at least one of the components - of properties similar to the ones of the fresh component - and its reuse for production of casting moulds and cores. However, at present, there is a lack of a reclaimed material assessment index, which could be applied for each type of moulding sands and reclaims. The most important criteria of the technological assessment of the reclaimed materials, which should be used, in order to determine the reclamation degree of spent moulding sands originated from the most often used foundry technologies, are presented in the hereby paper.

    A carcinogenic risk assessment for acrylonitrile in consumer products was prepared as part of the Second Workshop on Pragmatics of Risk Assessment, Bethesda, MD. Data from one inhalation and two oral rat bioassays served as input into several high-to-low-dose mathematical risk extrapolation models. The final unit risk estimates for humans were based on maximum likelihood estimates from the Global83 implementation of the multistage model after adjustments for surface area differences, continuous versus intermittent exposures, and the proportion of lifetime exposed. The unit risk estimates for lifetime exposure to 1 mg kg-1 day-1 by inhalation and ingestion were 0.0531 and 0.2385, respectively. These risks are equivalent to risks of 3.3 x 10(-8) for inhalation of 1 ppt in air and 3.4 x 10(-9) for ingestion of 1 ng day.-1

    Displacing natural gas and petroleum with carbon dioxide is a proven technology for producing conventional geologic hydrocarbon reservoirs, and producing additional yields from abandoned or partially produced petroleum reservoirs. Extending this concept to natural gas hydrate production offers the potential to enhance gas hydrate recovery with concomitant permanent geologic sequestration. Numerical simulation was used to assess a suite of carbon dioxide injection techniques for producing gas hydrates from a variety of geologic deposit types. Secondary hydrate formation was found to inhibit contact of the injected CO{sub 2} regardless of injectate phase state, thus diminishing the exchange rate due to pore clogging and hydrate zone bypass of the injected fluids. Additional work is needed to develop methods of artificially introducing high-permeability pathways in gas hydrate zones if injection of CO{sub 2} in either gas, liquid, or micro-emulsion form is to be more effective in enhancing gas hydrate production rates.

    The use of life-cycle assessment (LCA) to understand the embodied energy, environmental impacts, and potential energy-savings of manufactured products has become more widespread among researchers in recent years. This paper reviews recent LCA studies in the cement industry in China and in other countries and provides an assessment of the methodology used by the researchers compared to ISO LCA standards (ISO 14040:2006, ISO 14044:2006, and ISO/TR 14048:2002). We evaluate whether the authors provide information on the intended application, targeted audience, functional unit, system boundary, data sources, data quality assessment, data disaggregation and other elements, and draw conclusions regarding the level of adherence to ISO standards for the papers reviewed. We found that China researchers have gained much experience during last decade, but still have room for improvement in establishing boundaries, assessing data quality, identifying data sources, and explaining limitations. The paper concludes with a discussion of directions for future LCA research in China.

    In May of 2000, a meeting was convened in Kimberley, South Africa, and attended by representatives of the diamond industry and leaders of African governments to develop a certification process intended to assure that rough, exported diamonds were free of conflictual concerns. This meeting was supported later in 2000 by the United Nations in a resolution adopted by the General Assembly. By 2002, the Kimberley Process Certification Scheme (KPCS) was ratified and signed by both diamond-producing and diamond-importing countries. Over 70 countries were included as members at the end of 2007. To prevent trade in 'conflict' diamonds while protecting legitimate trade, the KPCS requires that each country set up an internal system of controls to prevent conflict diamonds from entering any imported or exported shipments of rough diamonds. Every diamond or diamond shipment must be accompanied by a Kimberley Process (KP) certificate and be contained in tamper-proof packaging. The objective of this study was to assess the alluvial diamond resource endowment and current production capacity of the alluvial diamond-mining sector in Ghana. A modified volume and grade methodology was used to estimate the remaining diamond reserves within the Birim and Bonsa diamond fields. The production capacity of the sector was estimated using a formulaic expression of the number of workers reported in the sector, their productivity, and the average grade of deposits mined. This study estimates that there are approximately 91,600,000 carats of alluvial diamonds remaining in both the Birim and Bonsa diamond fields: 89,000,000 carats in the Birim and 2,600,000 carats in the Bonsa. Production capacity is calculated to be 765,000 carats per year, based on the formula used and available data on the number of workers and worker productivity. Annual production is highly dependent on the international diamond market and prices, the numbers of seasonal workers actively mining in the sector, and

    Designing assessments and tests is one of the more challenging aspects of creating an accessible learning environment for students who are deaf or hard of hearing (DHH), particularly for deaf students with a disability (DWD). Standardized assessments are a key mechanism by which the educational system in the United States measures student progress, teacher effectiveness, and the impact of school reform. The diversity of student characteristics within DHH and DWD populations is only now becoming visible in the research literature relating to standardized assessments and their use in large-scale accountability reforms. The purpose of this article is to explore the theoretical frameworks surrounding assessment policy and practice, current research related to standardized assessment and students who are DHH and DWD, and potential implications for practice within both the assessment and instruction contexts.

    Alcohol-related health outcomes show strikingly high incidence in Hungary. The effects of alcohol consumption are influenced not only by the quantity, but also the quality of drinks; therefore, wine production can have an important effect on public health outcomes. Nevertheless, the Hungarian wine sector faces several vital problems and challenges influenced by the country's accession to the European Union and by the need for restructuring. A comprehensive health impact assessment (HIA) based on the evaluation of the Hungarian legislation related to the wine sector has been carried out, aiming to assess the impact of the production of quality wine versus that of table wine, using a range of public health and epidemiological research methods and data as well as HIA guidelines. The study finds that the toxic effects of alcohol can be reduced with an increased supply of quality wine and with decreased overall consumption due to higher cost, although this might drive some people to seek illegal sources. Quality wine production allows for improved use of land, creates employment opportunities and increases the incomes of producers and local communities; however, capital-scarce producers unable to manage restructuring may lose their source of subsistence. The supply of quality wine can promote social relations, contribute to a healthy lifestyle and reduce criminality related to alcohol's influence and adulteration. In general, the production and supply of quality wine can have an overall positive impact on health. Nevertheless, because of the several possible negative effects expected without purposeful restructuring, recommendations for the maximization of favourable outcomes and suggestions for monitoring the success of the analysis have been provided.

    Extending the frying-life of oils is of commercial and economic importance. Due to this fact, assessment on the thermal stability of frying oils could provide considerable savings to the food processors. In this study, the physico-chemical properties of five palm products mainly palm oil, single-fractionated palm olein, double-fractionated palm olein, red palm olein and palm-based shortening during 80 hours of heating at 180 degrees C were investigated. Heating properties of these products were then compared with that of high oleic sunflower oil, which was used as reference oil. The indices applied in evaluating the quality changes of oils were free fatty acid, smoke point, p-anisidine value, tocols, polar and polymer compounds. Three palm products i.e. palm oil, single-fractionated palm olein and double-fractionated palm olein were identified to be the most stable in terms of lower formation of free fatty acid, polar and polymer compounds as well as preserving higher smoke point and tocols content compared to the other three oils. The low intensity of hydrolytic and oxidative changes due to prolonged heating, suggests that these palm products are inherently suitable for frying purposes.

    Lactic acid has been an intermediate-volume specialty chemical (world production {approximately}50,000 tons/yr) used in a wide range of food-processing and industrial applications. Potentially, it can become a very large-volume, commodity-chemical intermediate produced from carbohydrates for feedstocks of biodegradable polymers, oxygenated chemicals, environmentally friendly ``green`` solvents, and other intermediates. In the past, efficient and economical technologies for the recovery and purification of lactic acid from fermentation broths and its conversion to the chemical or polymer intermediates had been the key technology impediments and main process cost centers. Development and deployment of novel separations technologies, such as electrodialysis with bipolar membranes, extractive and catalytic distillations, and chemical conversion, can enable low-cost production with continuous processes in large-scale operations. The emerging technologies can use environmentally sound lactic acid processes to produce environmentally useful products, with attractive process economics. These technology advances and recent product and process commercialization strategies are reviewed and assessed.

    Purpose: Osteogenesis imperfecta (OI) is a rare hereditary disease leading to multiple bone deformities and fractures. In the absence of causal therapy, a symptomatic approach is based on treatment with bisphosphonates and physiotherapy. The clinical and radiological manifestations vary. Therefore, standardization and quantification for an objective comparison, especially during therapy, are required. In this paper, radiological changes of the spine are quantified according to their clinical relevance to define a scoring system that transfers the morphological changes into a single value representing the severity of the disease. Materials and Methods: 268 lateral spine X-rays of 95 patients with OI (median age 5.6 years) were assessed. The findings were classified based on their clinical relevance. Results: The three criteria, vertebral compression, thoracolumbar kyphosis and deformity type, were quantified in a new grading system. Based on this, a 'severity classification' (1 to 5) was defined with implications for diagnostics and treatment. A mathematical formula that takes into account the three criteria and their correlations to clinical relevance, resulting in a 'severity score', was developed. Conclusion: 'Severity classification' and 'severity score' introduce a new concept for a standardized evaluation of spine X-rays in patients with OI. For both scientific and routine purposes, it provides the user with a simple and easy-to-handle tool for assessing and comparing different stages of severity prior to and during therapy with detailed accuracy.

    Full Text Available Biodiesel is defined as a fuel which may be used as pure biofuel or at high concentration in mineral oil derivatives, in accordance with specific quality standards for transport applications. The main raw material used for biodiesel production is rapeseed, which contains mono-unsaturated acids (about 60% and also poly-unsaturated fatty acids (C 18:1 and C 18:3 in a lower quantity, as well as some undesired saturated fatty acids (palmitic and stearic acids. Other raw materials have also been used in research and the industrial production of biodiesel (palm oil, sunflower oil, soybean oil, waste plant oil, animal fats, etc. The historical background of biodiesel production, installed industrial capacities, as well as the Directive of the European Parliament and of the Council (May 2003 regarding the promotion of the use of biofuels or other renewable fuels for transport are discussed in the first part of this article. The second part focuses on some new concepts for the future development of technology for biodiesel production, based on the application of non-catalytic transesterification under supercritical conditions or the use of lipases as an alternative catalyst for this reaction.

    We investigate the associated production of neutralinos $e^+e^-\\to\\tilde{\\chi}^0_1\\tilde{\\chi}^0_2$ accompanied by the neutralino leptonic decay $\\tilde{\\chi}^0_2\\to\\tilde{\\chi}^0_1 \\ell^+\\ell^-$, taking into account initial beam polarization and production-decay spin correlations in the minimal supersymmetric standard model with general CP phases but without generational mixing in the slepton sector. The stringent constraints from the electron EDM on the CP phases are also included in the discussion. Initial beam polarizations lead to three CP-even distributions and one CP-odd distribution, which can be studied independently of the details of the neutralino decays. We find that the production cross section and the branching fractions of the leptonic neutralino decays are very sensitive to the CP phases. In addition, the production-decay spin correlations lead to several CP-even observables such as lepton invariant mass distribution, and lepton angular distribution, and one interesting T-odd (CP-odd) triple p...

  15. Assessing the sound quality of a grand piano for different tuning standards

    Fastl, Hugo

    2003-10-01

    Grand pianos are tuned to a standard frequency of 440 Hz for a4. Eighty years ago, the tuning standard was lower, around 432 Hz. In Germany, a group of music lovers insists that the sound quality of a grand piano when tuned to 432 Hz is much superior to that of the same instrument when tuned to 440 Hz. Therefore, well-controlled psychoacoustic experiments were performed to check the validity of that argument. Using a Welte-Steinway reproduction grand piano of the Deutsches Museum Muenchen, with the exception of the tuning, all other features of the pieces of music used as stimuli could be kept the same. The advantage of using the Welte-Steinway lies in the fact that reproductions of the music of famous (deceased) artists are available, who at their time performed at a lower tuning standard. Recordings of the music played at 432 vs 440 Hz were made on DAT and presented to the subjects via headphones for sound quality evaluation. Psychophysical procedures like semantic differential or preference scaling by ``random access'' that have proven successful for the assessment of sound quality in the context of car interior sounds were used in the experiments.

    Four thermotolerant microalgae were isolated from tropical Taiwan and classified as members of Desmodesmus based on morphological and molecular studies. A platform was established to evaluate their biodiesel production-related traits, including thermotolerance, lipid productivity, lipid oxidative stability and auto-sedimentation. The findings demonstrated thermotolerance of all four species was at the same level, as all could live at 45 °C for 24 h and 50 °C for 8 h with mortality rates below 5% of cells. The lipid productivity of Desmodesmus sp. F2 reached 113 mg/L/d. Its saturated and monounsaturated fatty acids accounted for 75% of the FAMEs, and it required only 3.1 h to achieve 85% sedimentation. Comparing these traits to those of the other three Desmodesmus and microalgae in the literature, Desmodesmus sp. F2 is one of the best candidates for biodiesel production in tropical and subtropical areas. This platform effectively assessed traits of microalgae related to biodiesel production.

    We present a search for standard model Higgs boson production in association with a W boson in proton-antiproton collisions (p pmacr →W±H→ℓνb bmacr ) at a center of mass energy of 1.96 TeV. The search employs data collected with the CDF II detector which correspond to an integrated luminosity of approximately 1fb-1. We select events consistent with a signature of a single lepton (e±/μ±), missing transverse energy, and two jets. Jets corresponding to bottom quarks are identified with a secondary vertex tagging method and a neural network filter technique. The observed number of events and the dijet mass distributions are consistent with the standard model background expectations, and we set 95% confidence level upper limits on the production cross section times branching ratio ranging from 3.9 to 1.3 pb for Higgs boson masses from 110 to 150GeV/c2, respectively.

    We propose a simple, spatially invariant and probabilistic year-round Empirical Standardized Soil Moisture Index (ESSMI) that is designed to classify soil moisture anomalies from harmonized multi-satellite surface data into categories of agricultural drought intensity. The ESSMI is computed by fitting a nonparametric empirical probability density function (ePDF) to historical time-series of soil moisture observations and then transforming it into a normal distribution with a mean of zero and standard deviation of one. Negative standard normal values indicate dry soil conditions, whereas positive values indicate wet soil conditions. Drought intensity is defined as the number of negative standard deviations between the observed soil moisture value and the respective normal climatological conditions. To evaluate the performance of the ESSMI, we fitted the ePDF to the Essential Climate Variable Soil Moisture (ECV SM) v02.0 data values collected in the period between January 1981 and December 2010 at South-Central America, and compared the root-mean-square-errors (RMSE) of residuals with those of beta and normal probability density functions (bPDF and nPDF, respectively). Goodness-of-fit results attained with time-series of ECV SM values averaged at monthly, seasonal, half-yearly and yearly timescales suggest that the ePDF provides triggers of agricultural drought onset and intensity that are more accurate and precise than the bPDF and nPDF. Furthermore, by accurately mapping the occurrence of major drought events over the last three decades, the ESSMI proved to be spatio-temporal consistent and the ECV SM data to provide a well calibrated and homogenized soil moisture climatology for the region. Maize, soybean and wheat crop yields in the region are highly correlated (r > 0.82) with cumulative ESSMI values computed during the months of critical crop growing, indicating that the nonparametric index of soil moisture anomalies can be used for agricultural drought

    Extinction rates in the Anthropocene are three orders of magnitude higher than background and disproportionately occur in the tropics, home of half the world's species. Despite global efforts to combat tropical species extinctions, lack of high-quality, objective information on tropical biodiversity has hampered quantitative evaluation of conservation strategies. In particular, the scarcity of population-level monitoring in tropical forests has stymied assessment of biodiversity outcomes, such as the status and trends of animal populations in protected areas. Here, we evaluate occupancy trends for 511 populations of terrestrial mammals and birds, representing 244 species from 15 tropical forest protected areas on three continents. For the first time to our knowledge, we use annual surveys from tropical forests worldwide that employ a standardized camera trapping protocol, and we compute data analytics that correct for imperfect detection. We found that occupancy declined in 22%, increased in 17%, and exhibited no change in 22% of populations during the last 3-8 years, while 39% of populations were detected too infrequently to assess occupancy changes. Despite extensive variability in occupancy trends, these 15 tropical protected areas have not exhibited systematic declines in biodiversity (i.e., occupancy, richness, or evenness) at the community level. Our results differ from reports of widespread biodiversity declines based on aggregated secondary data and expert opinion and suggest less extreme deterioration in tropical forest protected areas. We simultaneously fill an important conservation data gap and demonstrate the value of large-scale monitoring infrastructure and powerful analytics, which can be scaled to incorporate additional sites, ecosystems, and monitoring methods. In an era of catastrophic biodiversity loss, robust indicators produced from standardized monitoring infrastructure are critical to accurately assess population outcomes and identify

    2016-10-01

    Regulatory policies governing the safety of genetic engineering (rDNA) and the resulting products (GMOs) have been contentious and divisive, especially in agricultural applications of the technologies. These tensions led to vastly different approaches to safety regulation in different jurisdictions, even though the intent of regulations-to assure public and environmental safety-are common worldwide, and even though the international scientific communities agree on the basic principles of risk assessment and risk management. So great are the political divisions that jurisdictions cannot even agree on the appropriate triggers for regulatory capture, whether product or process. This paper reviews the historical policy and scientific implications of agricultural biotechnology regulatory approaches taken by the European Union, USA and Canada, using their respective statutes and regulations, and then critically assesses the scientific underpinnings of each.

    Full Text Available There are various methods for determining the antioxidant activity. They are differing by the source of oxidation, oxidized compounds and methods for the measurement of oxidized compounds. Methods for determination of antioxidant activity provide a wide range of results, so the evaluation of the antioxidant activity should be carried out in several ways, and the results should be interpreted with caution. In assessing antioxidant capacity is necessary to consider not only the nature and content of the reducing agent in the test facility, but also the possibility of their mutual influence. The objects of research in this research work were Instant chicory (Leroux, Fried chicory (Leroux, Instant chicory (LLC Favorit, Instant chicory (LLC SlavKofe, Instant chicory with hawthorn (Iceberg Ltd and K, Instant chicory (LLC Flagistom, Instant chicory (Ltd.

    Full Text Available OBJECTIVES: To describe the development, validation and inter-rater reliability of an instrument to measure the quality of patient decision support technologies (decision aids. DESIGN: Scale development study, involving construct, item and scale development, validation and reliability testing. SETTING: There has been increasing use of decision support technologies--adjuncts to the discussions clinicians have with patients about difficult decisions. A global interest in developing these interventions exists among both for-profit and not-for-profit organisations. It is therefore essential to have internationally accepted standards to assess the quality of their development, process, content, potential bias and method of field testing and evaluation. METHODS: Scale development study, involving construct, item and scale development, validation and reliability testing. PARTICIPANTS: Twenty-five researcher-members of the International Patient Decision Aid Standards Collaboration worked together to develop the instrument (IPDASi. In the fourth Stage (reliability study, eight raters assessed thirty randomly selected decision support technologies. RESULTS: IPDASi measures quality in 10 dimensions, using 47 items, and provides an overall quality score (scaled from 0 to 100 for each intervention. Overall IPDASi scores ranged from 33 to 82 across the decision support technologies sampled (n = 30, enabling discrimination. The inter-rater intraclass correlation for the overall quality score was 0.80. Correlations of dimension scores with the overall score were all positive (0.31 to 0.68. Cronbach's alpha values for the 8 raters ranged from 0.72 to 0.93. Cronbach's alphas based on the dimension means ranged from 0.50 to 0.81, indicating that the dimensions, although well correlated, measure different aspects of decision support technology quality. A short version (19 items was also developed that had very similar mean scores to IPDASi and high correlation

    Full Text Available Measuring health outcomes includes risk and uncertainty. Quality of life assessment in health care has two main properties one is they are personal, the other is they are reflecting personal preferences. Because of patient preferences includes risk and uncertainty standard gambling theory used which is one of the quantitative techniques for assessment of patient preferences. Framing effect which is based on social psychology, shows that positive and negative framed information effects decision making. For this reason in this study we aim to discuss the role of framing effect on quality of life assessments when standart gambling theory was used. Results of this study show that compare to traditional framing effect, medical framework reveal opposite results. Patients show risk seeking behavior in positive framework and they show risk aversion behaviour in negative framework. We think that the results of this study provides useful information for understanding of how framing make a bias in asssessment of patient preferences. [TAF Prev Med Bull 2015; 14(4.000: 346-352

    The extent to which pilot instructors are trained to assess crew resource management (CRM) skills accurately during Line-Oriented Flight Training (LOFT) and Line Operational Evaluation (LOE) scenarios is critical. Pilot instructors must make accurate performance ratings to ensure that proper feedback is provided to flight crews and appropriate decisions are made regarding certification to fly the line. Furthermore, the Federal Aviation Administration's (FAA) Advanced Qualification Program (AQP) requires that instructors be trained explicitly to evaluate both technical and CRM performance (i.e., rater training) and also requires that proficiency and standardization of instructors be verified periodically. To address the critical need for effective pilot instructor training, the American Institutes for Research (AIR) reviewed the relevant research on rater training and, based on "best practices" from this research, developed a new strategy for training pilot instructors to assess crew performance. In addition, we explored new statistical techniques for assessing the effectiveness of pilot instructor training. The results of our research are briefly summarized below. This summary is followed by abstracts of articles and book chapters published under this grant.

    Full Text Available Livestock units are known as one of the most influential sectors in the environment pollution. Therefore, the aim of this study was to investigate the environmental impacts of milk production in Guilan province of Iran through Life Cycle Assessment (LCA methodology. The primary data were collected from 45 units of milk production through a field survey with the help of a structured questionnaire. The reliability was assessed using Cronbach’s alpha coefficient and was estimated an acceptable value of 0.91. The consumption of resources and emissions were allocated to a functional unit (FU of one ton of milk. Impacts of emissions in five impact categories of global warming, acidification, eutrophication, photochemical oxidation and depletion of resources were investigated. The results showed that the characterization index for these impact categories were 1831 kg CO2 eq, 7.97 kg SO2 eq, 3.42 kg PO4−3 eq, 0.21 kg C2H4 eq and 838.39 MJ, respectively. Final indices for these impact categories were calculated as 0.24, 0.28, 0.076, 0.017 and 0.046, respectively. Environmental index (EcoX and resources depletion index (RDI were obtained 0.61 and 0.04, respectively. In this study, the highest potential for environmental impacts of production revealed for acidification and followed by global warming impact category.

    2013-10-01

    Full Text Available Introduction: Tussilago farfara (coltsfoot, Petasites hybridus (common butterbur, Senecio vernalis (eastern groundsel and Symphytum officinale (comfrey are species traditionally used in phytotherapy that besides the therapeutic compounds contain toxic pyrrolizidine alkaloids (PAs. The aim of the paper is to determine the total PAs content and the phytotoxicity of the above species. Material and methods: The quantitative determination of pyrrolizidine alkaloids is based on the stoichiometric reaction of protonated alkaloids with methyl orange. In acidic conditions the dye is released from the complex and its color is assessed spectrophotometrically using a linear regression curve of senecionine as a standard. The phytotoxicity was assessed by Triticum bioassay that studies the effect of the extracts (0.001-5.00%, w/v upon root elongation (inhibitory concentration - IC50 and on the karyokinetic film. Results: The highest amount of total PAs was found in Senecio vernalis (654.8 ± 35.96 μg/g dry plant and the lowest in Petasites hybridus. The lowest IC50 was found for Tussilago farfara followed by Petasites hybridus, Senecio vernalis, and Symphytum officinale. The results were supported by microscopic examination. Conclusions: The results of the spectrophotometric assay are consistent with the ones found in the literature. All extracts inhibited the elongation of the main root of wheat caryopses, however, no correlation between phytotoxicity and the PAs concentration could be emphasized

    As part ofthe Consortium for Research on Renewable Industrial Materials' Phase I life-cycle assessments ofbiofuels, lifecycle inventory burdens from the production of bio-oil were developed and compared with measures for residual fuel oil. Bio-oil feedstock was produced using whole southern pine (Pinus taeda) trees, chipped, and converted into bio-oil by fast pyrolysis. Input parameters and mass and energy balances were derived with Aspen. Mass and energy balances were input to SimaPro to determine the environmental performance of bio-oil compared with residual fuel oil as a heating fuel. Equivalent functional units of 1 MJ were used for demonstrating environmental preference in impact categories, such as fossil fuel use and global warming potential. Results showed near carbon neutrality of the bio-oil. Substituting bio-oil for residual fuel oil, based on the relative carbon emissions of the two fuels, estimated a reduction in CO2 emissions by 0.075 kg CO2 per MJ of fuel combustion or a 70 percent reduction in emission over residual fuel oil. The bio-oil production life-cycle stage consumed 92 percent of the total cradle-to-grave energy requirements, while feedstock collection, preparation, and transportation consumed 4 percent each. This model provides a framework to better understand the major factors affecting greenhouse gas emissions related to bio-oil production and conversion to boiler fuel during fast pyrolysis.

  20. Integrating Hazardous Materials Characterization and Assessment Tools to Guide Pollution Prevention in Electronic Products and Manufacturing

    Science.gov (United States)

    Lam, Carl

    Due to technology proliferation, the environmental burden attributed to the production, use, and disposal of hazardous materials in electronics have become a worldwide concern. The major theme of this dissertation is to develop and apply hazardous materials assessment tools to systematically guide pollution prevention opportunities in the context of electronic product design, manufacturing and end-of-life waste management. To this extent, a comprehensive review is first provided on describing hazard traits and current assessment methods to evaluate hazardous materials. As a case study at the manufacturing level, life cycle impact assessment (LCIA)-based and risk-based screening methods are used to quantify chemical and geographic environmental impacts in the U.S. printed wiring board (PWB) industry. Results from this industrial assessment clarify priority waste streams and States to most effectively mitigate impact. With further knowledge of PWB manufacturing processes, select alternative chemical processes (e.g., spent copper etchant recovery) and material options (e.g., lead-free etch resist) are discussed. In addition, an investigation on technology transition effects for computers and televisions in the U.S. market is performed by linking dynamic materials flow and environmental assessment models. The analysis forecasts quantities of waste units generated and maps shifts in environmental impact potentials associated with metal composition changes due to product substitutions. This insight is important to understand the timing and waste quantities expected and the emerging toxic elements needed to be addressed as a consequence of technology transition. At the product level, electronic utility meter devices are evaluated to eliminate hazardous materials within product components. Development and application of a component Toxic Potential Indicator (TPI) assessment methodology highlights priority components requiring material alternatives. Alternative

    Welfare Quality® seems to develop into a standard for farm animal welfare assessment and European Fur Breeders’ Association initiated the “WelFur” project in 2009 in order to develop a welfare assessment protocol for mink and fox farms after the WQ standards. The assessment is based on four...... principles and 12 underlying criteria, to be measured at the farm.

    Over the last twenty years an increasing number of studies have relied on the standard definition of the Malmquist-Luenberger index proposed by Chung et al. (1997) [J. Environ. Manage., 51, 229-240], to assess environmental sensitive productivity change. While recent contributions have shown that it suffers from relevant drawbacks related to inconsistencies and infeasibilities, no one has studied systematically the performance of the original model, and to what extent the existing results are unreliable. We introduce the optimization techniques that implement the model by Aparicio et al. (2013) [Eur. J. Oper. Res., 229(3), 738-742] solving these problems, and using a country level database on air pollutants systematically compare the results obtained with both approaches. Over the 1995-2007 period environmental productivity stagnation prevails across developed and developing countries, and while increasing technical progress takes place in the later years, it is offset by declining efficiency. Results show also that inconsistencies and infeasibilities in the original model are increasing in the number of undesirable outputs included, reaching remarkable values that seriously question the reliability of results, and compromise any environmental policy recommendation based on them.

    Full Text Available Owing to its severe effect on productivity of rain-fed crops and indirect effect on employment as well as per capita income, agricultural drought has become a prime concern worldwide. The occurrence of drought is mainly a climatic phenomenon which cannot be eliminated. However, its effects can be reduced if actual spatio-temporal information related to crop status is available to the decision makers. The present study attempts to assess the efficiency of remote sensing and GIS techniques for monitoring the spatio-temporal extent of agricultural drought. In the present study, NOAA-AVHRR NDVI data were used for monitoring agricultural drought through NDVI based Vegetation Condition Index. VCI was calculated for whole Rajasthan using the long term NDVI images which reveals the occurrence of drought related crop stress during the year 2002. The VCI values of normal (2003 and drought (2002 year were compared with meteorological based Standardized Precipitation Index (SPI, Rainfall Anomaly Index and Yield Anomaly Index and a good agreement was found among them. The correlation coefficient between VCI and yield of major rain-fed crops (r > 0.75 also supports the efficiency of this remote sensing derived index for assessing agricultural drought.

    Full Text Available The Wada Test (WT is part of the presurgical evaluation for refractory epilepsy. The WT is not standardized and the protocols differ in important ways, including stimulus type of material presented for memory testing, timing of presentations and methods of assessment. The aim of this study was to contribute to establish parameters for a WT to Brazilian population investigating the performance of 100 normal subjects, without medication. Two parallel models were used based on Montreal Procedure adapted from Gail Risse's (MEG-MN,EUA protocol. The proportions of correct responses of normal subjects submitted to two parallel WT models were investigated and the two models were compared. The results showed that the two models are similar but significant differences among the stimulus type were observed. The results suggest that the stimulus type may influence the results of the WT and should be considered when constructing models and comparing different protocols.

    2007-02-01

    We developed the German Adaptation of the Personality Assessment Inventory (PAI; Morey, 1991) under careful consideration of current adaptation literature and guidelines. The adaptation process included the translation of the 344 items into German, a back translation into English as well as the testing of the language equivalence using a bilingual sample. We then standardized the final German version of the PAI for the German population. We compared the American and German norm and reliability data. The observed differences in PAI scale means did not exceed 5 T scores. Internal consistency reliability showed a similar pattern in both language versions, although the German alpha coefficients were on average slightly lower than the American ones. Factor structure was similar in both versions. We discuss expectations about the German PAI and possible problems for its practical usefulness for the German-speaking population.

    2015-01-01

    There is growing interest in the adaptation of psychological questionnaires in different countries, due to the need for cross-cultural research using the same tests adapted to diverse populations. This paper presents the standardization of the Personality Assessment Inventory (PAI; Morey, 1991, 2007) in Spain and Chile (both Spanish-speaking countries). The Spanish sample was made up of 940 people (461 men and 479 women), and the Chilean sample of 569 people (231 men and 338 women). Results revealed that the Chilean means were higher than those of the Spanish sample at confidence level 99.9%, although the associated effect sizes were generally small to moderate (partial eta-square between 0.008 and 0.187). Sex differences in the variables evaluated were commented on, and the importance of cross-cultural research and the influence of sex on personality and psychopathology variables were discussed.

    2011-04-15

    The enzymatic production of biodiesel by transesterification of cottonseed oil was studied using low cost crude pancreatic lipase as catalyst in a batch system. The effects of the critical process parameters including water percentage, methanol:oil ratio, enzyme concentration, buffer pH and reaction temperature were determined. Maximum conversion of 75-80% was achieved after 4 h at 37 C, pH 7.0 and with 1:15 M ratio of oil to methanol, 0.5% (wt of oil) enzyme and water concentration of 5% (wt of oil). Various organic solvents were tested among which a partially polar solvent (t-butanol) was found to be suitable for the reaction. The major fuel characteristics like specific gravity, kinematic viscosity, flash point and calorific value of the 20:80 blends (B20) of the fatty acid methyl esters with petroleum diesel conformed very closely to those of American Society for Testing Materials (ASTM) standards.

    Purpose The present study aimed to develop and standardize a screening tool for elderly people who wish to check for themselves their level of hearing loss. Methods The Self-assessment for Hearing Screening of the Elderly (SHSE) consisted of 20 questions based on the characteristics of presbycusis using a five-point scale: seven questions covered general issues related to sensorineural hearing loss, seven covered hearing difficulty under distracting listening conditions, two covered hearing difficulty with fast-rated speech, and four covered the working memory function during communication. To standardize SHSE, 83 elderly participants took part in the study: 25 with normal hearing, and 22, 23, and 13 with mild, moderate, and moderate-to-severe sensorineural hearing loss, respectively, according to their hearing sensitivity. All were retested 3 weeks later using the same questionnaire to confirm its reliability. In addition, validity was assessed using various hearing tests such as a sentence test with background noise, a time-compressed speech test, and a digit span test. Results SHSE and its subcategories showed good internal consistency. SHSE and its subcategories demonstrated high test–retest reliability. A high correlation was observed between the total scores and pure-tone thresholds, which indicated gradually increased SHSE scores of 42.24%, 55.27%, 66.61%, and 78.15% for normal hearing, mild, moderate, and moderate-to-severe groups, respectively. With regard to construct validity, SHSE showed a high negative correlation with speech perception scores in noise and a moderate negative correlation with scores of time-compressed speech perception. However, there was no statistical correlation between digit span results and either the SHSE total or its subcategories. A confirmatory factor analysis supported three factors in SHSE. Conclusion We found that the developed SHSE had valuable internal consistency, test–retest reliability, and convergent and construct

    Variability in medical practice in the United States leads to higher costs without achieving better patient outcomes. Clinical practice guidelines, which are intended to reduce variation and improve care, have several drawbacks that limit the extent of buy-in by clinicians. In contrast, standardized clinical assessment and management plans (SCAMPs) offer a clinician-designed approach to promoting care standardization that accommodates patients’ individual differences, respects providers’ clinical acumen, and keeps pace with the rapid growth of medical knowledge. Since early 2009 more than 12,000 patients have been enrolled in forty-nine SCAMPs in nine states and Washington, D.C. In one example, a SCAMP was credited with increasing clinicians’ rate of compliance with a recommended specialist referral for children from 19.6 percent to 75 percent. In another example, SCAMPs were associated with an 11–51 percent decrease in total medical expenses for six conditions when compared with a historical cohort. Innovative tools such as SCAMPs should be carefully examined by policy makers searching for methods to promote the delivery of high-quality, cost-effective care. PMID:23650325

    Energy Technology Data Exchange (ETDEWEB)

    Hanssen, Ole Joergen

    1997-12-31

    This thesis contributes to the development and testing of environmental life cycle assessment (LCA) in product development and management in industry. It is based on systems theory and systems engineering. It develops a method for sustainable product development that has been successfully tested in the Nordic project called NEP. The LCA method is also a basis for an optimization model, where life cycle economy and environmental impacts from product systems are optimized with a non-linear model. A more complete mathematical model for LCA, based on the functional requirements on a product system, is also developed. The statistical properties of emission factors are studied using a data set from the Swedish Kraft Mill industry. It is shown that emission factors may be assumed constants in the LCA model, but with rather large variations within a population of Kraft mills. It is shown that there are a few environmental impacts which are important for most types of products under Scandinavian conditions, especially global warming potential, acidification, human toxicity and fossil energy depletion. There are significant differences between the contribution to these impacts from different life cycle stages, where raw material processing and use of products are generally more important than the other stages. Test cases indicate that there are no large conflicts between improvements in environmental impacts and customer requirements. Environmental improvements seem to increase purchase cost of products in some cases, but the life cycle cost of the products seem in most cases to be reduced. It is concluded that there are opportunities for 30-50% improvements in product system, based on relatively simple modifications of the systems. 246 refs., 63 figs., 19 tabs.

  15. Search for the Standard Model Higgs Boson in associated production with w boson at the Tevatron

    Chun, Xu [Univ. of Michigan, Ann Arbor, MI (United States)

    2009-11-01

    A search for the Standard Model Higgs boson in proton-antiproton collisions with center-of-mass energy 1.96 TeV at the Tevatron is presented in this dissertation. The process of interest is the associated production of W boson and Higgs boson, with the W boson decaying leptonically and the Higgs boson decaying into a pair of bottom quarks. The dataset in the analysis is accumulated by the D0 detector from April 2002 to April 2008 and corresponding to an integrated luminosity of 2.7 fb-1. The events are reconstructed and selected following the criteria of an isolated lepton, missing transverse energy and two jets. The D0 Neural Network b-jet identification algorithm is further used to discriminate b jets from light jets. A multivariate analysis combining Matrix Element and Neural Network methods is explored to improve the Higgs boson signal significance. No evidence of the Higgs boson is observed in this analysis. In consequence, an observed (expected) limit on the ratio of σ (p$\\bar{p}$ → WH) x Br (H → b$\\bar{b}$) to the Standard Model prediction is set to be 6.7 (6.4) at 95% C.L. for the Higgs boson with a mass of 115 GeV.

  16. An assessment on hydrogen production using central receiver solar systems

    Bilgen, C.; Bilgen, E.

    An assessment is presented on hydrogen production using a dedicated central receiver solar system concept coupled to two types of hydrogen producing processes, electrolysis and thermochemical. The study on solar electrolytic hydrogen was carried out using solar electricity and four different electrolytic technologies, namely, industrial unipolar 1980 and 1983 technologies, industrial bipolar and solid polymer electrolyte technology. The thermochemical process was the sulphur/iodine cycle, which is being developed by General Atomic Co. Systems, which is capable of producing about one-million GJ hydrogen per year, was developed at the conceptual level, and site specific computations were carried out. A general mathematical model was developed to predict the optical and thermal performance of the central receiver system coupled directly to the chemical plant. Cost models were developed for each subsystem based on the database published in the literature. Levelized and delevelized costs of solar hydrogen were then computed.

    2013-02-01

    This study aims to evaluate energy, economic, and environmental performances of seven categories of biodiesel feedstocks by using the mixed-unit input-output life cycle assessment method. Various feedstocks have different environmental performances, indicating potential environmental problem-shift. Jatropha seed, castor seed, waste cooking oil, and waste extraction oil are preferred feedstocks for biodiesel production in the short term. Positive net energy yields and positive net economic benefits of biodiesel from these four feedstocks are 2.3-52.0% of their life cycle energy demands and 74.1-448.4% of their economic costs, respectively. Algae are preferred in the long term mainly due to their less arable land demands. Special attention should be paid to potential environmental problems accompanying feedstock choice: freshwater use, ecotoxicity potentials, photochemical oxidation potential, acidification potential and eutrophication potential. Moreover, key processes are identified by sensitivity analysis to direct future technology improvements. Finally, supporting measures are proposed to optimize China's biodiesel development.

    We introduce notions of ordinary and standard products of σ-finite measures and prove their existence. This approach allows us to construct invariant extensions of ordinary and standard products of Haar measures. In particular, we construct translation-invariant extensions of ordinary and standard Lebesgue measures on R∞ and Rogers-Fremlin measures on e∞, respectively, such that topological weights of quasi-metric spaces associated with these measures are maximal (i.e., 2c). We also solve some Fremlin problems concerned with an existence of uniform measures in Banach spaces.

    Full Text Available A more objective method for measuring the energy needs of businesses, System Energy Assessment (SEA, measures the combined impacts of material supply chains and service supply chains, to assess businesses as whole self-managing net-energy systems. The method is demonstrated using a model Wind Farm, and defines a physical measure of their energy productivity for society (EROI-S, a ratio of total energy delivered to total energy expended. Energy use records for technology and proxy measures for clearly understood but not individually recorded energy uses for services are combined for a whole system estimate of consumption required for production. Current methods count only energy needs for technology. Business services outsource their own energy needs to operate, leaving no traceable record. That uncounted business energy demand is often 80% of the total, an amount of “dark energy” hidden from view, discovered by finding the average energy estimated needs for businesses far below the world average energy consumed per dollar of GDP. Presently for lack of information the energy needs of business services are counted to be “0”. Our default assumption is to treat them as “average”. The result is a hard measure of total business demand for energy services, a “Scope 4” energy use or GHG impact assessment. Counting recorded energy uses and discounting unrecorded ones misrepresents labor intensive work as highly energy efficient. The result confirms a similar finding by Hall et al. in 1981 [1]. We use exhaustive search for what a business needs to operate as a whole, tracing internal business relationships rather than energy data, to locate its natural physical boundary as a working unit, and so define a business as a physical rather than statistical subject of scientific study.

    1998-08-27

    A modified rapid plate assay procedure was developed, that allowed quantifiable measurement of nisin production by Lactococcus lactis growing directly on agar media. Using this direct plate assay, several nutritional parameters were assessed for their influence on nisin production (as distinct from their influence on growth) by L. lactis subsp. lactis ATCC 11454 growing on standard M17 based media over 3 and 6 h incubation periods. Glucose was found to be the optimal carbon source tested, with glycerol having the greatest suppressive effect. The addition of salts suppressed nisin production on a per cell basis, except MnCl2. This direct plate method proved to be a good pilot assay for rapidly and quantifiably investigating the initial effects of different parameters on nisin production by L. lactis, prior to conducting more intensive broth batch culture assays. The data obtained in this study indicate that certain nutritional parameters can impose a repressive effect on nisin production. Elucidation of how these parameters control the amount of nisin produced will provide further insight into the regulation of nisin biosynthesis in L. lactis.

    2011-11-01

    Interviews with Chinese forest products manufacturers were conducted to explore their attitudes towards forest certification and related issues. Participants comprised owners, CEOs, and managers in 20 Chinese wood products companies, including producers of furniture, doors, flooring, and various engineered wood products. The interviews were used to analyze the extent to which participants were considering adopting forest certification and what might motivate such a decision. This was done by assessing their awareness and knowledge of certification. The results indicated that participants' understanding of forest certification was extremely low, despite major efforts in China to raise awareness of the issue. Potential economic benefits were the most frequently cited reason to adopt certification, including gaining or maintaining competitive advantage over their industry counterparts, improved access to both domestic and export markets, better customer recognition, and enhanced corporate responsibility practices. Some interviewees (3 out of 20) considered that certification would become a mandatory requirement or industry standard, and that this would be the only viable motivation for certification given that the financial benefits were potentially limited. According to the participants, the main differences between certified and uncertified wood products operations related to improved market access and public image. Interviewees felt that cooperation between and support from governments and the forest industry would enable the enhanced awareness of certification amongst manufacturers and the general public. This, in turn, could serve to stimulate demand for certified products.

    2013-01-01

    The growing need for valid assessment procedures of the outdoor thermal environment in the fields of public weather services, public health systems, urban planning, tourism & recreation and climate impact research raised the idea to develop the Universal Thermal Climate Index UTCI based on the most recent scientific progress both in thermo-physiology and in heat exchange theory. Following extensive validation of accessible models of human thermoregulation, the advanced multi-node 'Fiala' model was selected to form the basis of UTCI. This model was coupled with an adaptive clothing model which considers clothing habits by the general urban population and behavioral changes in clothing insulation related to actual environmental temperature. UTCI was developed conceptually as an equivalent temperature. Thus, for any combination of air temperature, wind, radiation, and humidity, UTCI is defined as the air temperature in the reference condition which would elicit the same dynamic response of the physiological model. This review analyses the sensitivity of UTCI to humidity and radiation in the heat and to wind in the cold and compares the results with observational studies and internationally standardized assessment procedures. The capabilities, restrictions and potential future extensions of UTCI are discussed.

  5. The standardized psychometric assessment of altered states of consciousness (ASCs) in humans.

    Dittrich, A

    1998-07-01

    The APZ questionnaire was developed in order to explore hypotheses on ASCs. First -- in a series of 11 experiments using different induction methods on N = 393 healthy subjects -- the hypothesis was tested that ASCs have major dimensions in common irrespective of the mode of their induction. In the International Study on Altered States of Consciousness (ISASC) the external validity of the experimental results was assessed. The ISASC was carried out on a total of N = 1133 subjects in six countries. The main results of the experimental studies were corroborated in the field studies. The results can be summarized as follows: the common denominator of ASCs is described by three oblique dimensions, designated as "Oceanic Boundlessness (OSE)", "Dread of Ego Dissolution (AIA)" and "Visionary Restructuralization (VUS)". The reliability and validity of the scales are satisfactory. Tested versions of the APZ scales are available in English (UK, USA), German, Italian and Portuguese. Psychometrically as yet untested versions exist in Dutch, Finnish, French, Greek, Spanish and Russian. The APZ questionnaire has become the international standard for the assessment of ASCs, thus helping to integrate research. A psychometrically improved version exists in German (OAV questionnaire). The BETA questionnaire, which measures the dimensions "Vigilance Reduction (VIR)" and "Auditive Alteration (AVE)" is also available in German. These dimensions are most likely etiology-dependent.

    2004-01-01

    This paper presents'new correlations for assessment of the likelihood of initiation (or triggering) of soil liquefaction. These new correlations eliminate several sources of bias intrinsic to previous, similar correlations, and provide greatly reduced overall uncertainty and variance. Key elements in the development of these new correlations are (1) accumulation of a significantly expanded database of field performance case histories; (2) use of improved knowledge and understanding of factors affecting interpretation of standard penetration test data; (3) incorporation of improved understanding of factors affecting site-specific earthquake ground motions (including directivity effects, site-specific response, etc.); (4) use of improved methods for assessment of in situ cyclic shear stress ratio; (5) screening of field data case histories on a quality/uncertainty basis; and (6) use of high-order probabilistic tools (Bayesian updating). The resulting relationships not only provide greatly reduced uncertainty, they also help to resolve a number of corollary issues that have long been difficult and controversial including: (1) magnitude-correlated duration weighting factors, (2) adjustments for fines content, and (3) corrections for overburden stress. ??

    2016-10-01

    The viability of a fusion reactor is preeminently conditioned by the tritium self-sufficiency. An assessment of different parameters representing the tritium production, as the tritium breeding ratio (TBR), the tritium production rate (TPR) density and their poloidal and radial variations along the PbLi breeder zones has been performed for the last DCLL DEMO designs developed in the frame of the EUROfusion Programme. The final overall value of 1.104 obtained allows accomplishing the fuel self-sufficiency requirement. This TBR value includes not only the contribution of the breeding blanket (BB) modules but also of the back supporting structure (BSS). The BSS design resulted fundamental to reach the 1.1 criterion. Lastly, the influence of the integration in the reactor of the heating and current drive (H&CD) systems that will penetrate the breeder volume has been evaluated. Assuming different configurations for them, the TBR loss has been determined. All the calculations have entailed the use of the particle transport Monte Carlo code MCNP5.

    2016-09-01

    The article deals with assessing the environmental impact of marl mining and cement production in Novorossiysk city (Krasnodar krai, Russia). The existing methods of studying the environmental effects caused by the cement industry have been reviewed. Soil and aquatic vegetation sampling has been carried out and the gross concentration of metals in the samples has been defined. The research has been conducted in the certified and accredited laboratory using emission spectral analysis. The external control has been carried out via X-ray fluorescence analysis. Based on the collected data, main chemical pollutants in soil cover and water area near the cement plant have been identified. The contaminants released by urban enterprises and motor vehicle emissions, as well as fugitive dust from dumps and the cement factory, lead to multi-element lithogeochemical anomaly at geochemical barriers in soils. Accumulation of pollutants in soil depends on the type of land use and the area relief. The most contaminated aquatic landscapes have been identified in the inner bay. According to this information, the technical proposals can be prepared for environmental safety management in strongly polluted city areas, as well as for the reclamation design in the areas currently experiencing the negative impact of cement production.

    Automatic segmentation of the endocardial surface in three-dimensional (3D) echocardiographic images is an important tool to assess left ventricular (LV) geometry and cardiac output (CO). The presence of speckle noise as well as the nonisotropic characteristics of the myocardium impose strong demands on the segmentation algorithm. In the analysis of normal heart geometries of standardized (apical) views, it is advantageous to incorporate a priori knowledge about the shape and appearance of the heart. In contrast, when analyzing abnormal heart geometries, for example in children with congenital malformations, this a priori knowledge about the shape and anatomy of the LV might induce erroneous segmentation results. This study describes a fully automated segmentation method for the analysis of non-standard echocardiographic images, without making strong assumptions on the shape and appearance of the heart. The method was validated in vivo in a piglet model. Real-time 3D echocardiographic image sequences of five piglets were acquired in radiofrequency (rf) format. These ECG-gated full volume images were acquired intra-operatively in a non-standard view. Cardiac blood flow was measured simultaneously by an ultrasound transit time flow probe positioned around the common pulmonary artery. Three-dimensional adaptive filtering using the characteristics of speckle was performed on the demodulated rf data to reduce the influence of speckle noise and to optimize the distinction between blood and myocardium. A gradient-based 3D deformable simplex mesh was then used to segment the endocardial surface. A gradient and a speed force were included as external forces of the model. To balance data fitting and mesh regularity, one fixed set of weighting parameters of internal, gradient and speed forces was used for all data sets. End-diastolic and end-systolic volumes were computed from the segmented endocardial surface. The cardiac output derived from this automatic segmentation was

    2016-09-01

    Full Text Available Background: Having considered increasing production of liquid and solid biofuels from rapeseed and bearing in mind its stable and unquestionable position in  the food and animal feed industries, a rational approach towards technologically and logistically efficient utilization of by-products from rapeseed processing is required. The aim of the research presented in the article is to assess the transport susceptibility of rapeseed meal fractions, varying according to particle size and chemical composition. Methods: Resistance to changes stimulating self-heating has been assumed as the main criterion of transport susceptibility. The following diagnostic variables have been experimentally determined: total protein, crude fat and crude fiber content, porosity, and water activity in the fraction of examined meal. In order to organize a set of particles and to indicate their optimal applications according to criteria chosen with regard to both  utilization and transportation, two aggregate indicators have been calculated. Results: It has been proved that medium-sized particle fractions (0.075-0.4 mm exhibit the lowest transport susceptibility, whereas the those with the largest granulations (>3 mm -have the highest. One significant relationship is the decline of feeding value and concurrent increase in the transport susceptibility of meal fractions, which in practice means that those fractions least-favoured by the animal feed industry can be least cumbersome to transport. Conclusions: It has been suggested that there should be a division of rapeseed meal into two products with different applications and different transport susceptibility. The fractioning of meal can bring numerous, measurable benefits for the meal industry and logistics processes for solid biofuels, where storage and transport properties have considerable importance, alongside commodity price and transport costs.

  18. A methodology to assess water availability for food production under climate change

    2012-04-01

    In many countries around the world, water demand for agricultural production already exceeds water availability. Such situation imposes a challenge for food production under future climate change conditions and indicates the need for a policy assessment in order to identify adaptation strategies in the water sector. This contribution provides a methodology to compute water availability for irrigation using a GIS-based model, called "Water Availability and Adaptation Policy Assessment" (WAAPA). The model computes the net water availability for consumptive use for a river basin taking into account the regulation capacity of its water supply system and a set of management standards defined through water policy. The model was applied in 567 basins that cover the entire continental territory of Spain to estimate water availability under different climate change projections. The outputs of the PRUDENCE European project provide the information of the climate change scenarios. Two alternatives of management are proposed based on: reducing water allocation for agriculture, in order to obtain satisfactory water supply reliability or maintaining current water allocation for agriculture, but with the probability of reducing supply reliability. The results show equilibrium between water availability and agricultural demand in current conditions in the great majority of the River Basin Districts of Spain, nonetheless under climate change scenarios, the capability to satisfy the water requirements for agricultural production is significantly reduced, so as the management needs are necessary to mitigate the expected impacts to long term.

    The Viciafaba root tip micronucleus test is one of the most employed plant genotoxicity assays, and has been used on various types of contaminated materials. This test has been standardized by AFNOR, the French member organization of ISO. However, this test is usually performed with a water extraction step but soil genotoxicity assessment would be more relevant when performed directly in the soil itself. In order to harmonize these protocols, an ISO standard for the V.faba micronucleus test in both liquid phase (exposure of plants to different liquid matrix, including soil water extracts) and solid phase (direct exposure of plants to the soil) would be very useful. In this context, we compared two exposure durations in the solid phase (48 h and 5 d) for the V.faba micronucleus test with two different well-known genotoxicants, maleic hydrazide and copper sulfate. We concluded that these two durations induced equivalent sensitivity: the micronucleus frequency was significantly increased with 5 μmol maleic hydrazide per kg dry soil and with 2 mmol copper sulfate per kg dry soil with both exposure durations. However, exposing roots to soil during 48 h is more practical. Moreover, organically and conventionally cultured seeds were employed to determine whether the seed provenance influenced the test sensitivity. Organic seeds were less sensitive to copper, possibly because copper-based treatments are permitted, and often applied, in organic farms. Therefore, in the absence of completely non-treated seeds, organically-cultured seeds did not appear to offer any advantages over conventional seeds.

    Full Text Available Background: One of the methods used for standard setting is the borderline regression method (BRM. This study aims to assess the reliability of BRM when the pass-fail standard in an objective structured clinical examination (OSCE was calculated by averaging the BRM standards obtained for each station separately. Materials and Methods: In nine stations of the OSCE with direct observation the examiners gave each student a checklist score and a global score. Using a linear regression model for each station, we calculated the checklist score cut-off on the regression equation for the global scale cut-off set at 2. The OSCE pass-fail standard was defined as the average of all station′s standard. To determine the reliability, the root mean square error (RMSE was calculated. The R2 coefficient and the inter-grade discrimination were calculated to assess the quality of OSCE. Results: The mean total test score was 60.78. The OSCE pass-fail standard and its RMSE were 47.37 and 0.55, respectively. The R2 coefficients ranged from 0.44 to 0.79. The inter-grade discrimination score varied greatly among stations. Conclusion: The RMSE of the standard was very small indicating that BRM is a reliable method of setting standard for OSCE, which has the advantage of providing data for quality assurance.

    Background: Salmorejo is gaining national reputation and international recognition. However, there are many different forms to prepare it and, therefore, the organoleptic and nutritional properties of the plateful may differ. Material and methods: In order to make standardization of salmorejoand its ways of production, which allow the protection of its identity and, furthermore, its nutritional characterization, around the 83% of catering establishments were surveyed in Cordoba (excluding suburbs and industrial area), to investigate how they produce this dish, as to name, ingredients, preparation, price, etc. They were personally given a survey with 55 questions divided into 6 sections. Results: The result is that only 21% of establishments used the name “salmorejo cordobés”, the ingredients used, consistently statistically adjusted to a previous proposal of systematization and nutritional assessment, based on literature data and broadcast in over 50 languages which corresponds to 1.000 g tomato, 200 g telerabread, 100 g of extra virgin olive oil, 5 g Montalbangarlic and 10g of salt. Then, 100g of this product corresponds to 117.4 kcal, 1.8 g protein, 8.1 g fat, 9.9 g carbohydrate, 1.2 g fiber and 380.7 mg of sodium. A minority of the establishments used vinegar like an extra ingredient (18% of surveys) and the majority used little pieces of ham and boiled egg as garnish. While more than 25% add a trickle of oil on the finished product. It is made mainly through glass mixer or food processor, being the majority recipe used form of family origin. Although salmorejowas traditionally considered a food for summer, 78% of establishments have it all year round. 94% of establishments consider it among the ten most ordered dishes, and in 18% it is the most ordered dish of the establishment. There is no relationship between the amount of salmorejo served with the price of the plateful, the latter being in line with other prices of the rest of establishment. Conclusions

    Forest is one of the main sources of carbon stock. Forest plays a key role in sustainable management by providing different aspects of forest ecosystem such as source of timber products, provide of clean water, food sources, etc. A study was conducted to assess carbon pools in selected production forest of Pahang, Malaysia. There are five main types of carbon pools that are recognized available in the forest, i.e. aboveground biomass (AGB), belowground biomass (BGB), deadwood, litter and soil; that these components of carbon pools can accumulate and release carbon into the atmosphere. Five sites with different years of logging period representing status of the forest were selected (i.e. before logging (PU), immediate after logging (P0), after 10 (P10), 20 (P20) and 30 (P30) years of logging). Twenty plots of 0.25 ha (50 m × 50 m) each were established with a total sampling area of 1.0 ha at each site. All trees with ≥10 cm diameter at breast height (dbh) were tagged, identified and measured. Soil at 0-30 cm, litter and dead wood were sampled and collected in every each of sub-plots to determine and assess carbon stocks within sites. The results indicated that AGB carbon had highest portion of carbon compared to soil, BGB, deadwood and litter, which comprised about 63% of the total carbon pools. It was followed by soil and BGB that comprised about 22% and 13%, respectively. Deadwood and litter contributes the same percentage which is about 1%. In terms of status of the forest, AGB contained the highest carbon which is range from 110.49 tC ha-1 to 164.49 tC ha-1 compared with soil (33.72 tC ha-1 to 68.51 tC ha-1), BGB tC ha-1 to 34 tC ha-1), deadwood (1.57 tC ha-1 to 5.55 tC ha-1) and litter (1.42 tC ha-1 to 2.19 tC ha-1). Results from this study will be very helpful as baseline of carbon storage in different status of forest from before harvesting to logged-over forest and the impact of harvesting on the carbon stock in Pahang and Peninsular Malaysia as a whole.

  5. Exergetic life cycle assessment of hydrogen production from renewables

    Granovskii, Mikhail; Dincer, Ibrahim; Rosen, Marc A.

    Life cycle assessment is extended to exergetic life cycle assessment and used to evaluate the exergy efficiency, economic effectiveness and environmental impact of producing hydrogen using wind and solar energy in place of fossil fuels. The product hydrogen is considered a fuel for fuel cell vehicles and a substitute for gasoline. Fossil fuel technologies for producing hydrogen from natural gas and gasoline from crude oil are contrasted with options using renewable energy. Exergy efficiencies and greenhouse gas and air pollution emissions are evaluated for all process steps, including crude oil and natural gas pipeline transportation, crude oil distillation and natural gas reforming, wind and solar electricity generation, hydrogen production through water electrolysis, and gasoline and hydrogen distribution and utilization. The use of wind power to produce hydrogen via electrolysis, and its application in a fuel cell vehicle, exhibits the lowest fossil and mineral resource consumption rate. However, the economic attractiveness, as measured by a "capital investment effectiveness factor," of renewable technologies depends significantly on the ratio of costs for hydrogen and natural gas. At the present cost ratio of about 2 (per unit of lower heating value or exergy), capital investments are about five times lower to produce hydrogen via natural gas rather than wind energy. As a consequence, the cost of wind- and solar-based electricity and hydrogen is substantially higher than that of natural gas. The implementation of a hydrogen fuel cell instead of an internal combustion engine permits, theoretically, an increase in a vehicle's engine efficiency of about of two times. Depending on the ratio in engine efficiencies, the substitution of gasoline with "renewable" hydrogen leads to (a) greenhouse gas (GHG) emissions reductions of 12-23 times for hydrogen from wind and 5-8 times for hydrogen from solar energy, and (b) air pollution (AP) emissions reductions of 38

    Livestock production has a variety of environmental impacts such as greenhouse gas emissions, water pollution, acidification, and primary energy consumption. The demand for livestock products is expected to grow substantially, creating even more environmental pressure. The use of specialty feed ingredients (SFI) such as supplemented AA and phytase can reduce nutrient input into the system without compromising productivity and consequently can reduce emissions. The global change impact of using SFI in pig and broiler production systems in Europe and North and South America was studied. A life cycle assessment according to international standards (ISO 14040/44) analyzed contributions from producing SFI and animals to global change. Three different alternatives were analyzed. In addition, partial sensitivity analysis was conducted using 5 scenarios for each region for both production systems. Specialty feed ingredient supplementation in pig and broiler diets reduced greenhouse gas emissions (cradle to farm gate) by 56% and 54% in Europe, 17% and 15% in North America, and 33% and 19% in South America, respectively, compared to an unsupplemented diet. A total of 136 Mt CO equivalent (CO eq) was saved in 2012, rising to 146 Mt CO eq in 2050 on the basis of United Nations population projections. Considerable benefits of supplementation with SFI were apparent in European and South American diets when direct land use change was considered because of the reduced demand for soybean meal. The eutrophication potential of unsupplemented diets was reduced by up to 35% in pig and 49% in broiler production systems compared to supplemented alternatives. The acidification potential of supplemented strategies was reduced by up to 30% in pig and 79% in broiler production systems. The primary energy demand was similar in all alternatives, and this could be an area where the SFI industry can improve. Overall, SFI supplementation substantially reduced the global warming, eutrophication

    2011-01-01

    A more objective method for measuring the energy needs of businesses, System Energy Assessment (SEA), identifies the natural boundaries of businesses as self-managing net-energy systems, of controlled and self-managing parts. The method is demonstrated using a model Wind Farm case study, and applied to defining a true physical measure of its energy productivity for society (EROI-S), the global ratio of energy produced to energy cost. The traceable needs of business technology are combined with assignable energy needs for all other operating services. That serves to correct a large natural gap in energy use information. Current methods count traceable energy receipts for technology use. Self-managing services employed by businesses outsource their own energy needs to operate, and leave no records to trace. Those uncounted energy demands are often 80% of the total embodied energy of business end products. The scale of this "dark energy" was discovered from differing global accounts, and corrected so the average...

    Full Text Available Bangladesh is one of the vulnerable countries of the world for natural disasters. Drought is one of the common and severe calamities in Bangladesh that causes immense suffering to people in various ways. The present research has been carried out to examine the frequency of meteorological droughts in Bangladesh using the long-term rainfall data of 30 meteorological observatories covering the period of 1948–2011. The study uses the highly effective Standardized Precipitation Index (SPI for drought assessment in Bangladesh. By assessing the meteorological droughts and the history of meteorological droughts of Bangladesh, the spatial distributions of meteorological drought indices were also analysed. The spatial and temporal changes in meteorological drought and changes in different years based on different SPI month intervals were analysed. The results indicate that droughts were a normal and recurrent feature and it occurred more or less all over the country in virtually all climatic regions of the country. As meteorological drought depends on only rainfall received in an area, anomaly of rainfall is the main cause of drought. Bangladesh experienced drought in the years 1950, 1951, 1953, 1954, 1957, 1958, 1960, 1961, 1962, 1963, 1965, 1966, 1967 and 1971 before independence and after independence Bangladesh has experienced droughts in the years 1972, 1973, 1975, 1979, 1980, 1983, 1985, 1992, 1994, 1995, 2002, 2004, 2006, 2009 and 2011 during the period 1948–2011. The study indicated that Rajshahi and its surroundings, in the northern regions and Jessore and its surroundings areas, the island Bhola and surrounding regions, in the south-west region, were vulnerable. In the Sylhet division, except Srimongal, the areas were not vulnerable but the eastern southern sides of the districts Chittagong, Rangamati, Khagrachhari, Bandarban and Teknaf were vulnerable. In the central regions, the districts of Mymensingh and Faridpur were more vulnerable

    The authors developed and qualified an automated routine screening tool to quantify hair shine. This tool is able to separately record individual properties of hair shine such as specular reflection and multiple reflection, as well as additional features such as sparkle, parallelism of hair fibers, and hair color, which strongly affect the subjective ranking by individual readers. A side-by-side comparison of different hair care and styling products with regard to hair shine using the automated screening tool in parallel with standard panel assessment showed that the automated system provides an almost identical ranking and the same statistical significances as the panel assessment. Provided stringent stratification of hair fibers for color and parallelism, the automated tool competes favorably with panel assessments of hair shine. In this case, data generated with the opsira Shine-Box are clearly superior over data generated by panel assessment in terms of reliability and repeatability, workload and time consumption, and sensitivity and specificity to detect differences after shampoo, conditioner, and leave-in treatment. The automated tool is therefore well suited to replace standard panel assessments in claim support, at least as a screening tool. A further advantage of the automated system over panel assessments is the fact that absolute numeric values are generated for a given hair care product, whereas panel assessments can only give rankings of a series of hair care products included in the same study. Thus, the absolute numeric data generated with the automated system allow comparison of hair care products between studies or at different time points after treatment.

    Full Text Available SUMMARY. The lungs are complex 3D structuresstudied in the clinic and the laboratory using histologic or imaging sections. Although such 2D analyses of lung structure are considered “gold standards”, the information conveyed is often insufficient and does not represent the whole organ. Stereology, the mathematical approach to the analysis of 3D structures via 2D sampling and morphometry, the practical application of stereology, provide solutions to this problem, but had until recently not been systematically adoptedin pneumology. In an effort of minimizing the above-mentioned methodological problems and of standardizing the quantitative assessment of lung structure, the American Thoracic Society and European Respiratory Society formed a task force, which recently published its findings. The task force aimed at comprehensively reviewing current stereologic methods for lung morphometry, formulating practical guidelines for using unbiased methods for basic and translational research of lung structure, and examining the extensions of stereologic methods on non-invasive imaging of lung architecture. In the statement of the task force are included useful directives with important application in the laboratory and the clinic, the most pertinent of which are discussed in the present mini-review.

    A bacterial spore assay and a molecular DNA microarray method were compared for their ability to assess relative cleanliness in the context of bacterial abundance and diversity on spacecraft surfaces. Colony counts derived from the NASA standard spore assay were extremely low for spacecraft surfaces. However, the PhyloChip generation 3 (G3) DNA microarray resolved the genetic signatures of a highly diverse suite of microorganisms in the very same sample set. Samples completely devoid of cultivable spores were shown to harbor the DNA of more than 100 distinct microbial phylotypes. Furthermore, samples with higher numbers of cultivable spores did not necessarily give rise to a greater microbial diversity upon analysis with the DNA microarray. The findings of this study clearly demonstrated that there is not a statistically significant correlation between the cultivable spore counts obtained from a sample and the degree of bacterial diversity present. Based on these results, it can be stated that validated state-of-the-art molecular techniques, such as DNA microarrays, can be utilized in parallel with classical culture-based methods to further describe the cleanliness of spacecraft surfaces.

    One of the major requirements for a fusion power plant in the future is tritium self-sufficiency. For this reason the scientific community has dedicated a lot of effort to research activity on reactor tritium breeding blankets. In the framework of the international project DEMO, many concepts of breeding blanket have been taken into account and some of them will be tested in the experimental reactor ITER by means of appropriate test blanket modules (TBMs). All the breeding blanket concepts rely on the adoption of binary systems composed of a material acting as neutronic multiplier and another as a breeder. This paper addresses a neutronic feature of these kinds of systems. In particular, attention has been focused on the assessment of the importance of neutrons coming from multiplication reactions for the production of tritium. A theoretical framework has been set up and a procedure to evaluate the performance of the multiplier-breeder systems, under the aforementioned point of view, has been developed. Moreover, the model set up has been applied to helium cooled lithium lead and helium cooled pebble bad TBMs under irradiation in ITER and the results have been critically discussed.

    Agricultural drought assessment is an important tool for water management in water-scarce regions such as Inner Mongolia and northeastern China. Conventional methods have difficulty of clarifying long-term influences of drought on regional agricultural production. To accurately evaluate regional agricultural drought, we assessed the performance of drought indices by constructing a new assessment framework with three components: crop model calibration and validation, drought index calculation, and index assessment (standard period setting, mean value and agreement assessments). The Environmental Policy Integrated Climate (EPIC) model simulated well of county-level wheat and maize yields in the nine investigated counties. We calculated a major crop-specific index yield reduction caused by water stress (WSYR) in the EPIC crop model, by relating potential and rainfed yields. Using 26 agricultural drought cases, we compared WSYR with two meteorological drought indices: precipitation (P) and aridity index (AI). The results showed that WSYR had greater agreement (85 %) than either the precipitation (65 %) or aridity index (68 %). The temporal trend of the indices over the period 1962-2010 was tested using three approaches. The result via WSYR revealed a significant increase in the trend of agricultural drought in drought-prone counties, which could not be shown by the precipitation and aridity indices. Total number of dry year via WSYR from 1990s to 2000s increases more sharply than via P or AI. As shown by WSYR, the number of dry years in northeastern China and Inner Mongolia is generally increasing, particularly after the 2000s, in the western part of the study area. The study reveals the usefulness of the framework for drought index assessment and indicates the potential of WSYR and possible drought cases for drought classification.

    We aimed to compare the standardized central review of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT scans performed after induction therapy for follicular lymphoma (FL) in the PRIMA study (Salles et al., Lancet 377:42-51, 2011; Trotman et al., J Clin Oncol 29:3194-3200, 2011) to scan review at local centres. PET/CT scans were independently evaluated by two nuclear medicine physicians using the 2007 International Harmonization Project (IHP) criteria (Cheson et al., J Clin Oncol 25:579-586, 2007; Juweid et al., J Clin Oncol 25:571-578, 2007; Shankar et al., J Nucl Med 47:1059-1066, 2006) and Deauville 5-point scale (5PS) criteria (Meignan et al., Leuk Lymphoma 50:1257-1260, 2009; Meignan et al., Leuk Lymphoma 51:2171-2180, 2010; Barrington et al., Eur J Nucl Med Mol Imaging 37:1824-1833, 2010). PET/CT status was compared with prospectively recorded patient outcomes. Central evaluation was performed on 119 scans. At diagnosis, 58 of 59 were recorded as positive, with a mean maximum standardized uptake value (SUV{sub max}) of 11.7 (range 4.6-35.6). There was no significant association between baseline SUV{sub max} and progression-free survival (PFS). Sixty post-induction scans were interpreted using both the IHP criteria and 5PS. Post-induction PET-positive status failed to predict progression when applying the IHP criteria [p = 0.14; hazard ratio (HR) 1.9; 95 % confidence interval (CI) 0.8-4.6] or 5PS with a cut-off ≥3 (p = 0.12; HR 2.0; 95 % CI 0.8-4.7). However, when applying the 5PS with a cut-off ≥4, there was a significantly inferior 42-month PFS in PET-positive patients of 25.0 % (95 % CI 3.7-55.8 %) versus 61.4 % (95 % CI 45.4-74.1 %) in PET-negative patients (p = 0.01; HR 3.1; 95 % CI 1.2-7.8). The positive predictive value (PPV) of post-induction PET with this liver cut-off was 75 %. The 42-month PFS for patients remaining PET-positive by local assessment was 31.1 % (95 % CI 10.2-55.0 %) vs 64.6 % (95 % CI 47.0-77.6 %) for PET

    This collaborative study characterizes a homogeneous standard for the protein content determination of granulocyte colony-stimulating factor (G-CSF) products with traceability of the measurement. The Kjeldahl method was used to determine the average protein content of G-CSF bulk as 2.505 mg/ml (95% C.I: 2.467-2.543 mg/ml, GCV 4.0%). Using G-CSF bulk as a traceability benchmark, the protein content of the final freeze-dried standard using reverse phase HPLC (RP-HPLC) was 215.4 μg protein per ampoule (95% C.I: 212.407-218.486 μg/ampoule, GCV 3.4%). A comparative study showed that there was no difference between using Filgrastim CRS (European Pharmacopeia G-CSF reference standard) and freeze-dried homogeneous standard when quantifying G-CSF protein content by RP-HPLC (P > 0.05). However, there were significant differences in the G-CSF protein content obtained using a serum albumin standard by Lowry assay and a G-CSF standard with RP-HPLC. Therefore, use of RP-HPLC with a freeze-dried homogeneous standard would eliminate the systematic errors introduced when using a serum albumin standard because of the differences in protein composition between the standard and the sample. It would also be helpful to use this method to compare the quality of G-CSF biosimilar products in situations where the protein content has been calibrated using various standards.

    Ocean Surface Currents are one of the most important ocean properties for oceanographers and operators in the maritime domain. Improved monitoring of ocean currents is systematically the number one requirement that emerges from any science or end user requirement surveys.Wavemill is a novel hybrid interferometric SAR system first proposed by ESA/ESTEC [Buck, 2005]. It offers the possibility of generating two-dimensional wide swath, high resolution, high precision maps of surface current vectors and ocean topography [Buck et al., 2009]. Based on a single spacecraft, it avoids the difficulties of synchronisation and baseline estimation associated with other interferometric SAR systems based on two or more satellites (e.g. the "cartwheel" or "helix" concept).The Wavemill concept has developed steadily since its first inception in 2005. A number of Wavemill studies in recent years have gradually put together facts and figures to support the case for Wavemill as a possible space-borne mission.The Wavemill Product Assessment study (WaPA) aimed to define the scientific capabilities and limitations of a spaceborne Wavemill instrument in preparation for a possible submission of the Wavemill concept as a candidate Earth Explorer Core mission. The WaPA project team brought together expert scientists and engineers in the field of SAR imaging of ocean currents, and included the National Oceanography Centre (UK), Starlab (Spain), IFREMER (France) and Airbus Defence and Space (UK). Overall project management was provided by Satellite Oceanographic Consultants (UK). The approach taken included:- A review of SAR imaging of ocean currents in along-track interferometric mode to learn from previous experiments and modelling what key phenomena need to be accounted for to determine the true performance of a spaceborne Wavemill system- Validation of proposed Wavemill primary products based on Wavemill airborne proof-of-concept data and numerical simulations to determine the capabilities

    1999-07-01

    The aim of this project was to assess the risk due to inhalation of radon and its decay products using an horizontal approach across a large scale research programme. The central objective was the assessment of human risk which requires combination of several topics involving a multidisciplinary approach. In the Aerosol Studies Group, progress was achieved in improvement, calibration and automation of experimental techniques for continuous and integrated measurements of the unattached fraction f{sub p}- and equilibrium factor F- values. Measurements were performed to determine the variation of size distributions of unattached and aerosol-associated radon decay products under typical living conditions. All aerosol groups performed controlled chamber studies to understand the basic behaviour of airborne activity concentrations. Measurements were performed to determine neutralisation rates of {sup 218}Po, to understand the cluster growth with residence time and to understand the hygroscopic growth of aerosol particles. In the Modelling Group, the programme RADEP has been developed to calculate the weighted committed equivalent lung dose per unit exposure of radon progeny (H{sub w}/P{sub p}) which implements the ICRP Publication 66 Human Respiratory Tract Model (HRTM). The stochastic deposition model (IDEAL) has been compared with the deposition model used by the HRTM, and the agreement between the two deposition models was excellent. A deterministic radon progeny dosimetry model (RADOS) has been developed. This model includes all bronchial airway generations compared with the HRTM that groups the 16 airway generations into three regions. Initial calculations with RADOS show that the basal and secretory cell doses are slightly smaller compared with that of the HRTM. A sensitivity analysis has been performed that has identified those HRTM model parameters that most affect the Hw/Pp.

    Full Text Available The crucial environmental issue due to fossil fuel use in our society and industries and more and more perceived by the communities is stimulating the development of innovative technologies with the scope of reducing GHGs and pollutants emissions, improving plants efficiency and exploiting renewable energy sources. The idea proposed in the present work links this context: a novel hybrid plant for the production of a mixture of methane and hydrogen (20%vol, called enriched-methane, from a steam reforming reactor whose heat duty is supplied by a concentrating solar power (CSP plant by means of a molten salt stream is here conceived, modelled and assessed. The enriched-methane mixture can be applied in methane internal combustion engines (ICE reducing CO, CO2, unburned emissions and improving engine efficiency. Moreover, the residual sensible heat of solar-heated molten salt stream can be used to generate medium-pressure steam and to produce electricity by a steam-turbine. Therefore, the plant proposed is co-generative, producing both hydrogen and electricity from a solar source. The behaviour of methane steam reforming reactor is simulated by means of a 2D mathematical model and the design of a cogenerative solar plant is proposed, evaluating its potentialities in terms of MWh of electricity produced and number of vehicles fed by enriched-methane. A single CSP module (surface requirement = 1.5 hectares coupled with a 4-tubes-and-shell shaped reactor is able to produce 686 tons/year of hydrogen, equivalent to 3.430 tons/year of 20%vol H2-CH4 mixture and 3.097 MWh/year of clean electricity.

    Full Text Available Talbina is a food product with high potential applications as a functional food. Talbina was prepared from two barley varieties namely: Giza126 and Giza130 by adding whole barley flour to water (1:10 w/v and (1:5 w/v for germinated barley then heating at  80° C for 5 minutes with continuous stirring until reaching a porridge like texture. The present investigation was carried out in an attempt to clearly the nutritional assessment of talbina as a functional food. The study included the determination of gross chemical composition, caloric value, mineral composition, vitamins composition and the amino acids composition. Meanwhile, computation of the chemical scores (CS and A/E ratios were carried out for raw, germinated barley, talbina, germinated talbina and commercial talbina. The data revealed that protein content of the all raw studied and processing treatments ranged from 8.75-18.34g/100g on dry weight basis. Besides, the all treatments recorded rather slight decrease in crude fat content. Likewise, ash and carbohydrates ranged between 2.29-2.86 and 73.40-82.66%, respectively. Whereas crude fiber had an increase after treatments and it ranged from 3.83-4.37%. On the other hand by making talbina iron, manganese, copper and zinc increased especially zinc, which recorded higher value than that recommended daily. Furthermore, germinated talbina130 recorded the highest amounts of vitamins B2, Nicotinic acid, B6 and folic acid. Moreover, the present study indicated that phenylalanine was the highest essential amino acid, followed by leucine.

    The Next Generation Science Standards (NGSS) explicitly treat Earth and Space Science (ESS) content with the same level of priority as Physical Science, Life Science, and Engineering & Technology. Therefore, the geoscience community has a vested interest in the use of NGSS as it is being implemented in K-12 classrooms. Individuals and groups from all facets of the geosciences can take action to support the implementation of the NGSS. That action will be most effective if it is guided by a thorough understanding of the needs of teachers and other stakeholders who have a role to play in NGSS implementation. This session will describe qualitative and quantitative needs assessment data that was gathered in advance of the Summit Meeting on the Implementation of the NGSS at the State Level, which was jointly organized in April 2015 by the American Geosciences Institute (AGI) and the National Association of Geoscience Teachers (NAGT). The data to be discussed are from interviews and quantitative survey data, as well as data based on responses by the 50+ Summit attendees who represented a variety of perspectives in geoscience education. Particular attention will be given to areas where responses suggested points of tension, such as the fact that many survey respondents feel that they understand dimensions of the NGSS that their colleagues do not understand as well, making for a potentially difficult context in which to work to implement the NGSS. Actions suggested by the Summit attendees that are related to the different need areas will also be described, with the intent being to open discussion among session participants about additional actions that they can take individually and/or collectively. The overarching goal of this presentation will be to work in coordination with the other presentations in the session to expand the network of member of the geoscience community who are informed and committed to supporting NGSS implementation.

    Cardiac output (Q) and stroke volume (V(S)) represent primary determinants of cardiovascular performance and should therefore be determined for performance diagnostics purposes. Since it is unknown, whether measurements of Q and V(S) can be performed by means of Innocor during standard graded exercise tests (GXTs), and whether current GXT stages are sufficiently long for the measurements to take place, we determined Q and V(S) at an early and late point in time on submaximal 2 min GXT stages. 16 male cyclists (age 25.4 +/- 2.9 years, body mass 71.2 +/- 5.0 kg) performed three GXTs and we determined Q and V(S) after 46 and 103 s at 69, 77, and 85% peak power. We found that the rebreathings could easily be incorporated into the GXTs and that Q and V(S) remained unchanged between the two points in time on the same GXT stage (69% peak power, Q: 18.1 +/- 2.1 vs. 18.2 +/- 2.3 l min(-1), V(S): 126 +/- 18 vs. 123 +/- 21 ml; 77% peak power, Q: 20.7 +/- 2.6 vs. 21.0 +/- 2.3 l min(-1), V(S): 132 +/- 18 vs. 131 +/- 18 ml; 85% peak power, Q: 21.6 +/- 2.4 vs. 21.8 +/- 2.7 l min(-1), V(S): 131 +/- 17 vs. 131 +/- 22 ml). We conclude that Innocor may be a useful device for assessing Q and V(S) during GXTs, and that the adaptation of Q and V(S) to exercise-to-exercise transitions at moderate to high submaximal power outputs is fast enough for 1 and 2 min GXT stage durations.

  18. The Use of Bayesian Networks to Assess the Quality of Evidence from Research Synthesis: 2. Inter-Rater Reliability and Comparison with Standard GRADE Assessment.

    Full Text Available The grades of recommendation, assessment, development and evaluation (GRADE approach is widely implemented in systematic reviews, health technology assessment and guideline development organisations throughout the world. We have previously reported on the development of the Semi-Automated Quality Assessment Tool (SAQAT, which enables a semi-automated validity assessment based on GRADE criteria. The main advantage to our approach is the potential to improve inter-rater agreement of GRADE assessments particularly when used by less experienced researchers, because such judgements can be complex and challenging to apply without training. This is the first study examining the inter-rater agreement of the SAQAT.We conducted two studies to compare: a the inter-rater agreement of two researchers using the SAQAT independently on 28 meta-analyses and b the inter-rater agreement between a researcher using the SAQAT (who had no experience of using GRADE and an experienced member of the GRADE working group conducting a standard GRADE assessment on 15 meta-analyses.There was substantial agreement between independent researchers using the Quality Assessment Tool for all domains (for example, overall GRADE rating: weighted kappa 0.79; 95% CI 0.65 to 0.93. Comparison between the SAQAT and a standard GRADE assessment suggested that inconsistency was parameterised too conservatively by the SAQAT. Therefore the tool was amended. Following amendment we found fair-to-moderate agreement between the standard GRADE assessment and the SAQAT (for example, overall GRADE rating: weighted kappa 0.35; 95% CI 0.09 to 0.87.Despite a need for further research, the SAQAT may aid consistent application of GRADE, particularly by less experienced researchers.

    Full Text Available An evaluation of 28 commercially available toys imported into New Zealand revealed that 21% of these toys do not meet the acoustic criteria in the ISO standard, ISO 8124-1:2009 Safety of Toys, adopted by Australia and New Zealand as AS/NZS ISO 8124.1:2010. While overall the 2010 standard provided a greater level of protection than the earlier 2002 standard, there was one high risk toy category where the 2002 standard provided greater protection. A secondary set of toys from the personal collections of children known to display atypical methods of play with toys, such as those with autism spectrum disorders (ASD, was part of the evaluation. Only one of these toys cleanly passed the 2010 standard, with the remainder failing or showing a marginal-pass. As there is no tolerance level stated in the standards to account for interpretation of data and experimental error, a value of +2 dB was used. The findings of the study indicate that the current standard is inadequate in providing protection against excessive noise exposure. Amendments to the criteria have been recommended that apply to the recently adopted 2013 standard. These include the integration of the new approaches published in the recently amended European standard (EN 71 on safety of toys.

  6. Indirect water management through Life Cycle Assessment: Fostering sustainable production in developing countries

    Science.gov (United States)

    Pfister, S.; Bayer, P.; Koehler, A.; Hellweg, S.

    2009-04-01

    Life Cycle Assessment (LCA) represents a methodological framework for analyzing the total environmental impact of any product or service of our daily life. After tracking all associated emissions and the consumption of resources, this impact is expressed with respect to a few common impact categories. These are supposed to reflect major societal and environmental priorities. However, despite their central role in environmental processes, to date hydrological as well as hydrogeological aspects are only rarely considered in LCA. Compared with standard impact categories within LCA, water is special. In contrast to other abiotic resources such as crude oil, it can be replenished. Total freshwater resources are immense, but not evenly distributed and often scarce in regions of high demand. Consequently, threads to natural water bodies have immense spatial dependency. Setting up functional relationships in order to derive a generally valid and practicable evaluation is tedious due to the complex, insufficiently understood, and uncertain natural processes involved. LCA that includes the environmental effects of water consumption means global indirect water resource management. It supports goal-directed consumer behaviour that aims to reduce pressure on natural water systems. By developing a hydrologically-based assessment of potential impacts from human interaction with natural water bodies, "greener" products can be prioritised. More sustainable and environmentally friendly water management is the result. The proposed contribution presents an operational assessment method of global surface water consumption for impacts on human health and ecosystem quality within a LCA framework. A major focus is the issue of how such global assessment helps to quantify potential impacts from water-intensive production in developing countries, where the means for proper water management are often limited. We depict a compensation scheme for impacts related to water consumption that

  15. Risk assessment of exposure to radon decay products

    Energy Technology Data Exchange (ETDEWEB)

    Monchaux, G

    1999-07-01

    The aim of this project was to assess the risk due to inhalation of radon and its decay products using an horizontal approach across a large scale research programme. The central objective was the assessment of human risk which requires combination of several topics involving a multidisciplinary approach. In the Aerosol Studies Group, progress was achieved in improvement, calibration and automation of experimental techniques for continuous and integrated measurements of the unattached fraction f{sub p}- and equilibrium factor F- values. Measurements were performed to determine the variation of size distributions of unattached and aerosol-associated radon decay products under typical living conditions. All aerosol groups performed controlled chamber studies to understand the basic behaviour of airborne activity concentrations. Measurements were performed to determine neutralisation rates of {sup 218}Po, to understand the cluster growth with residence time and to understand the hygroscopic growth of aerosol particles. In the Modelling Group, the programme RADEP has been developed to calculate the weighted committed equivalent lung dose per unit exposure of radon progeny (H{sub w}/P{sub p}) which implements the ICRP Publication 66 Human Respiratory Tract Model (HRTM). The stochastic deposition model (IDEAL) has been compared with the deposition model used by the HRTM, and the agreement between the two deposition models was excellent. A deterministic radon progeny dosimetry model (RADOS) has been developed. This model includes all bronchial airway generations compared with the HRTM that groups the 16 airway generations into three regions. Initial calculations with RADOS show that the basal and secretory cell doses are slightly smaller compared with that of the HRTM. A sensitivity analysis has been performed that has identified those HRTM model parameters that most affect the Hw/Pp.

  1. Advances in life cycle assessment and emergy evaluation with case studies in gold mining and pineapple production

    Science.gov (United States)

    Ingwersen, Wesley W.

    Life cycle assessment (LCA) is an internationally standardized framework for assessing the environmental impacts of products that is rapidly evolving to improve understanding and quantification of how complex product systems depend upon and affect the environment. This dissertation contributes to that evolution through the development of new methods for measuring impacts, estimating the uncertainty of impacts, and measuring ranges of environmental performance, with a focus on product systems in non-OECD countries that have not been well characterized. The integration of a measure of total energy use, emergy, is demonstrated in an LCA of gold from the Yanacocha mine in Peru in the second chapter. A model for estimating the accuracy of emergy results is proposed in the following chapter. The fourth chapter presents a template for LCA-based quantification of the range of environmental performance for tropical agricultural products using the example of fresh pineapple production for export in Costa Rica that can be used to create product labels with environmental information. The final chapter synthesizes how each methodological contribution will together improve the science of measuring product environmental performance.

    Woolf, D K; Padhani, A R; Makris, A

    2015-06-01

    Bone is the most common site for breast cancer metastases, occurring in up to 70% of those with metastatic disease. In order to effectively manage these patients, it is essential to have consistent, reproducible and validated methods of assessing response to therapy. We present current clinical practice of imaging response assessment of bone metastases. We also review the biology of bone metastases and measures of response assessment including clinical assessment, tumour markers and imaging techniques; bone scans (BSs), computed tomography (CT), positron emission tomography, magnetic resonance imaging (MRI) and whole-body diffusion-weighted MRI (WB DW-MRI). The current standard of care of BSs and CT has significant limitations and are not routinely recommended for the purpose of response assessment in the bones. WB DW-MRI has the potential to address this unmet need and should be evaluated in clinical trials.

  5. Can multicriteria assessment tools help build trust into organic products?

    Directory of Open Access Journals (Sweden)

    Bernhard Freyer

    2014-12-01

    Full Text Available In a continuously expanding, globalizing, and industrializing organic market, organic consumers confront increasing complexity in organic product representation, labeling, and information that challenges how they build trust in organic products. We present a conceptual framework to analyze how consumers might build and practice trust in the organic agrifood chain. We asked specifically about the role of multicriteria assessment tools (MCATs for trust building. We identified three consumer trust types: uninformed trust in labels (type 1; informed trust in extensive information, control, and certification (type 2; and informed and engaged trust in forms of close farmer-consumer relationships (type 3. Three concepts of "reflexivity" - unreflective, reflective, self-reflective - are used to explain how these three consumer trust types are operating. We see MCATs as tools accepted and applied mainly by the informed and reflective type. We further examined how reflexivity about two aspects - ethics and systems thinking - in the context of the organic agrifood chain can affect how people trust. Hedonistic, materialistic-oriented consumers might not care about MCATs to deepen their trust in organic, while anthropocentric-oriented consumers were identified as those applying MCATs; eco-centric and holistic-oriented consumers perceive MCATs more as a confinement that limits their self-reflexive and holistic understanding of organic. Awareness of, and interest in, systems thinking by unreflective and uninformed consumer trust types is rather limited; any MCAT is therefore without relevance. The reflective and informed consumer trust type uses a bundle of systems thinking methodologies, and in this context, MCATs would serve as an orientation. The self-reflective, informed, and engaged consumer trust type applies systems theory to learn how to become independent and to better learn how to protect against power interventions; e.g., from industries into the

    1997-12-31

    Fission product release (FPR) assessment for End Fitting Failure (EFF) in CANDU reactor loaded with CANFLEX-natural uranium (NU) fuel bundles has been performed. The predicted results are compared with those for the reactor loaded with standard 37-element bundles. The total channel I-131 release at the end of transient for EFF accident is calculated to be 380.8 TBq and 602.9 TBq for the CANFLEX bundle and standard bundle channel cases, respectively. They are 4.9% and 7.9% of total inventory, respectively. The lower total releases of the CANFLEX bundle O6 channel are attributed to the lower initial fuel temperatures caused by the lower linear element power of the CANFLEX bundle compared with the standard bundle. 4 refs., 1 fig., 4 tabs.

    Gregg, Evan O; Minet, Emmanuel; McEwan, Michael

    2013-09-01

    There are established guidelines for bioanalytical assay validation and qualification of biomarkers. In this review, they were applied to a panel of urinary biomarkers of tobacco smoke exposure as part of a "fit for purpose" approach to the assessment of smoke constituents exposure in groups of tobacco product smokers. Clinical studies have allowed the identification of a group of tobacco exposure biomarkers demonstrating a good doseresponse relationship whilst others such as dihydroxybutyl mercapturic acid and 2-carboxy-1-methylethylmercapturic acid - did not reproducibly discriminate smokers and non-smokers. Furthermore, there are currently no agreed common reference standards to measure absolute concentrations and few inter-laboratory trials have been performed to establish consensus values for interim standards. Thus, we also discuss in this review additional requirements for the generation of robust data on urinary biomarkers, including toxicant metabolism and disposition, method validation and qualification for use in tobacco products comparison studies.

    Full Text Available Companies are increasingly conducting life cycle assessments (LCA of their products to understand potential product impacts on the environment, prioritize areas of innovation to create more sustainable products, and determine valid claims. This case study shows the results of product innovation by comparing an older (2007 and new (2013 version of a common hygiene product in Europe and the U.S. The standard methodology follows the ISO 14040/44 Guidelines for LCA. Results are reported for the impact indicators with high relevance for the product category: primary energy, global warming, particulates, agricultural land occupation, fossil fuel depletion, and solid waste generation. Generally, raw material supply chains for product and packaging contribute most (up to 82% to the calculated environmental impact indicators. Improvements vs. the 2007 baby wipe range between 4% and 14% in Europe and between 15% and 36% in the U.S. The improvement is driven by a new substrate technology that provides more surface area for cleaning, which results in lower use of resources. This case study illustrates three key environmental drivers behind this innovation: the corporate focus on R&D capability to design for environmentally improved products, the increased interest from retailers and consumers requiring accurate and relevant information on the performance and sustainability of products, and the company’s interest in deeper technical understanding of contributions from upstream material and process innovations on a product’s environmental profile.

    To evaluate the technical quality of breast ultrasound based on American College of Radiology(ACR) standards. Between March 2002 and July 2002, ninety three breast sonograms obtained from 73 institutions were evaluated based on ACR standards for the hardware, technical settings, labeling of the images and identification. Of 93 breast sonograms, a satisfactory compliance with all ACR standards in the performance of breast US examinations was documented in 31% while the remaining 69% did not fully meet all ACR standards. 4.3% of breast US examinations were performed with a convex transducers, and the focal zone was inappropriately positioned in 14.2%. Gray-scale gain was subjectively characterized as inappropriate in 26.9%, and the size of lesion was not measured in 7.5%. Anatomic location of lesions was inappropriately described in 9.3%. The orientation of an US transducer was not properly labeled on any images in 33.3%. Inadequate recording of patient's information was noted in 43.3%. 50% of sonograms at University medical centers and larger general hospitals fully met all ACR standards while 36.8% at radiologic clinics and 12.1% at other private clinics met all ACR standards. Overall, 69% of breast sonograms failed to meet the quality criteria of the ACR standards. Therefore, it is essential to educate the basic technical details in performing breast US for the quality control.

    Despite evidence linking shrimp farming to several cases of environmental degradation, there remains a lack of ecologically meaningful information about the impacts of effluent on receiving waters. The aim of this study was to determine the biological impact of shrimp farm effluent, and to compare and distinguish its impacts from treated sewage effluent. Analyses included standard water quality/sediment parameters, as well as biological indicators including tissue nitrogen (N) content, stable isotope ratio of nitrogen (δ 15N), and amino acid composition of inhabitant seagrasses, mangroves and macroalgae. The study area consisted of two tidal creeks, one receiving effluent from a sewage treatment plant and the other from an intensive shrimp farm. The creeks discharged into the western side of Moreton Bay, a sub-tropical coastal embayment on the east coast of Australia. Characterization of water quality revealed significant differences between the creeks, and with unimpacted eastern Moreton Bay. The sewage creek had higher concentrations of dissolved nutrients (predominantly NO-3/NO-2 and PO3-4, compared to NH+4 in the shrimp creek). In contrast, the shrimp creek was more turbid and had higher phytoplankton productivity. Beyond 750 m from the creek mouths, water quality parameters were indistinguishable from eastern Moreton Bay values. Biological indicators detected significant impacts up to 4 km beyond the creek mouths (reference site). Elevated plant δ 15N values ranged from 10·4-19·6‰ at the site of sewage discharge to 2·9-4·5‰ at the reference site. The free amino acid concentration and composition of seagrass and macroalgae was used to distinguish between the uptake of sewage and shrimp derived N. Proline (seagrass) and serine (macroalgae) were high in sewage impacted plants and glutamine (seagrass) and alanine (macroalgae) were high in plants impacted by shrimp effluent. The δ 15N isotopic signatures and free amino acid composition of inhabitant
