  13. Mir Contamination Observations and Implications to the International Space Station

    NASA Technical Reports Server (NTRS)

    Soares, Carlos; Mikatarian, Ron

    2000-01-01

    A series of external contamination measurements were made on the Russian Mir Space Station. The Mir external contamination observations summarized in this paper were essential in assessing the system level impact of Russian Segment induced contamination on the International Space Station (ISS). Mir contamination observations include results from a series of flight experiments: CNES Comes-Aragatz, retrieved NASA camera bracket, Euro-Mir '95 ICA, retrieved NASA Trek blanket, Russian Astra-II, Mir Solar Array Return Experiment (SARE), etc. Results from these experiments were studied in detail to characterize Mir induced contamination. In conjunction with Mir contamination observations, Russian materials samples were tested for condensable outgassing rates in the U.S. These test results were essential in the characterization of Mir contamination sources. Once Mir contamination sources were identified and characterized, activities to assess the implications to ISS were implemented. As a result, modifications in Russian materials selection and/or usage were implemented to control contamination and mitigate risk to ISS.

    2014-01-01

    The International Space Station (ISS) is the largest and most complex on-orbit platform for space science utilization in low Earth orbit. Multiple sites for external payloads, with exposure to the associated natural and induced environments, are available to support a variety of space science utilization objectives. Contamination is one of the induced environments that can impact performance, mission success and science utilization on the vehicle. The ISS has been designed, built and integrated with strict contamination requirements to provide low levels of induced contamination on external payload assets. This paper addresses the ISS induced contamination environment at attached payload sites, both at the requirements level as well as measurements made on returned hardware, and contamination forecasting maps being generated to support external payload topology studies and science utilization.

  15. Emergency department management of patients internally contaminated with radioactive material

    SciTech Connect

    Kazzi, Ziad; Buzzell, Jennifer; Bertelli, Luiz; Christensen, Doran

    2014-11-15

    After a radiation emergency that involves the dispersal of radioactive material, patients can become externally and internally contaminated with one or more radionuclides. Internal contamination can lead to the delivery of harmful ionizing radiation doses to various organs and tissues or the whole body. The clinical consequences can range from acute radiation syndrome (ARS) to the long term development of cancer. Estimating the amount of radioactive material absorbed into the body can guide the management of patients. Treatment includes, in addition to supportive care and long term monitoring, certain medical countermeasures like Prussian blue, Calcium DTPA and Zinc DTPA.

  18. Analysis of a case of internal contamination with cobalt radioisotopes.

    PubMed

    Vrba, T; Malatova, I; Jurochova, B

    2007-01-01

    Internal contamination by compounds of cobalt radioisotopes occurs time to time at nuclear power plants. Intakes and committed effective doses are estimated by biokinetic models described in ICRP publications. The paper deals with a case of internal contamination of a worker engaged in a maintenance task at NPP Dukovany. In this case significant discrepancy was observed between intakes based on various datasets (whole body counting, analysis of urine and faeces) when default model setting was used. The reason of this phenomenon was searched for. Three different least square methods of fits were used to find out possible effect of a fitting method. The measured data were fitted by set of biokinetic functions, which covered all intake ways (ingestion and inhalation) and types (M, S, different AMADs and different f1) of the contaminant. The biokinetic model of cobalt needs further improvements as to find better agreement between data fit from direct measurements and bioassay.

  20. Anatomy of open access publishing: a study of longitudinal development and internal structure

    PubMed Central

    2012-01-01

    Background Open access (OA) is a revolutionary way of providing access to the scholarly journal literature made possible by the Internet. The primary aim of this study was to measure the volume of scientific articles published in full immediate OA journals from 2000 to 2011, while observing longitudinal internal shifts in the structure of OA publishing concerning revenue models, publisher types and relative distribution among scientific disciplines. The secondary aim was to measure the share of OA articles of all journal articles, including articles made OA by publishers with a delay and individual author-paid OA articles in subscription journals (hybrid OA), as these subsets of OA publishing have mostly been ignored in previous studies. Methods Stratified random sampling of journals in the Directory of Open Access Journals (n = 787) was performed. The annual publication volumes spanning 2000 to 2011 were retrieved from major publication indexes and through manual data collection. Results An estimated 340,000 articles were published by 6,713 full immediate OA journals during 2011. OA journals requiring article-processing charges have become increasingly common, publishing 166,700 articles in 2011 (49% of all OA articles). This growth is related to the growth of commercial publishers, who, despite only a marginal presence a decade ago, have grown to become key actors on the OA scene, responsible for 120,000 of the articles published in 2011. Publication volume has grown within all major scientific disciplines, however, biomedicine has seen a particularly rapid 16-fold growth between 2000 (7,400 articles) and 2011 (120,900 articles). Over the past decade, OA journal publishing has steadily increased its relative share of all scholarly journal articles by about 1% annually. Approximately 17% of the 1.66 million articles published during 2011 and indexed in the most comprehensive article-level index of scholarly articles (Scopus) are available OA through journal

    2015-10-01

    The practice of outpatient general internal medicine requires a diverse and evolving knowledge base. General internists must identify practice-changing shifts in the literature and reflect on their impact. Accordingly, we conducted a review of practice-changing articles published in outpatient general internal medicine in 2014. To identify high-quality, clinically relevant publications, we reviewed all titles and abstracts published in the following primary data sources in 2014: New England Journal of Medicine, Journal of the American Medical Association (JAMA), Annals of Internal Medicine, JAMA Internal Medicine, and the Cochrane Database of Systematic Reviews. All 2014 primary data summaries from Journal Watch-General Internal Medicine and ACP JournalWise also were reviewed. The authors used a modified Delphi method to reach consensus on inclusion of 8 articles using the following criteria: clinical relevance to outpatient internal medicine, potential for practice change, and strength of evidence. Clusters of important articles around one clinical question were considered as a single-candidate series. The article merits were debated until consensus was reached on the final 8, spanning a variety of topics commonly encountered in outpatient general internal medicine.

  2. Internal contamination of an irradiator discovered during security enhancement.

    PubMed

    Harvey, R P

    2014-08-01

    High-risk radioactive sources regulated under Increased Controls Regulations have been protected by licensed facilities, but the federal government has placed significant emphasis on these sources and has developed initiatives to assist radioactive material licensees. The Department of Energy's Global Threat Reduction Initiative (GTRI) Domestic Threat Reduction Program is a voluntary federally funded program for security enhancements of high-risk radiological material. During the hardening or security enhancement process by the United States Department of Energy (U.S. DOE) contractors, a small amount of radioactive contamination was discovered in a Cesium irradiator. Ultimately, it was decided to pursue disposal with U.S. DOE's Off-Site Recovery Program (OSRP). Radiological devices may have a leaking source or known internal contamination that may cause difficulty during security enhancement. If the licensee understands this, it may provide facilities the opportunity to plan and prepare for unusual circumstances.

    2015-08-01

    Filling a needed scholarly publishing avenue for astronomy education researchers and earth science education researchers, the Journal of Astronomy & Earth Sciences Education- JAESE was first published in 2014. JAESE is a scholarly, peer-reviewed scientific journal publishing original discipline-based education research and evaluation, with an emphasis of significant scientific results derived from ethical observations and systematic experimentation in science education and evaluation. International in scope, JAESE aims to publish the highest quality and timely articles from discipline-based education research that advance understanding of astronomy and earth sciences education and are likely to have a significant impact on the discipline or on policy. Articles are solicited describing both (i) systematic science education research and (ii) evaluated teaching innovations across the broadly defined Earth & space sciences education, including the disciplines of astronomy, climate education, energy resource science, environmental science, geology, geography, agriculture, meteorology, planetary sciences, and oceanography education. The publishing model adopted for this new journal is open-access and articles appear online in GoogleScholar, ERIC, EBSCO, ProQuest, and NASA SAO/ADS and are searchable in catalogs of 440,000 libraries that index online journals of its type. Rather than paid for by library subscriptions or by society membership dues, the annual budget is covered by page-charges paid by individual authors, their institutions, grants or donors: This approach is common in scientific journals, but is relatively uncommon in education journals. Authors retain their own copyright. The journal is owned by the Clute Institute in the United States, which owns and operates 17 scholarly journals and currently edited by former American Astronomical Society Education Officer Tim Slater, who is an endowed professor at the University of Wyoming and a Senior Scientist at the

    Objectives Measurement of soil contamination levels has been considered a feasible method for dose estimation of internal radiation exposure following the Chernobyl disaster by means of aggregate transfer factors; however, it is still unclear whether the estimation of internal contamination based on soil contamination levels is universally valid or incident specific. Methods To address this issue, we evaluated relationships between in vivo and soil cesium-137 (Cs-137) contamination using data on internal contamination levels among Minamisoma (10–40 km north from the Fukushima Daiichi nuclear power plant), Fukushima residents 2–3 years following the disaster, and constructed three models for statistical analysis based on continuous and categorical (equal intervals and quantiles) soil contamination levels. Results A total of 7987 people with a mean age of 55.4 years underwent screening of in vivo Cs-137 whole-body counting. A statistically significant association was noted between internal and continuous Cs-137 soil contamination levels (model 1, p value <0.001), although the association was slight (relative risk (RR): 1.03 per 10 kBq/m2 increase in soil contamination). Analysis of categorical soil contamination levels showed statistical (but not clinical) significance only in relatively higher soil contamination levels (model 2: Cs-137 levels above 100 kBq/m2 compared to those <25 kBq/m2, RR=1.75, p value <0.01; model 3: levels above 63 kBq/m2 compared to those <11 kBq/m2, RR=1.45, p value <0.05). Conclusions Low levels of internal and soil contamination were not associated, and only loose/small associations were observed in areas with slightly higher levels of soil contamination in Fukushima, representing a clear difference from the strong associations found in post-disaster Chernobyl. These results indicate that soil contamination levels generally do not contribute to the internal contamination of residents in Fukushima; thus, individual

    The discovery of polonium (Po) was first published in July, 1898 by P. Curie and M. Curie. It was the first element to be discovered by the radiochemical method. Polonium can be considered as a famous but neglected element: only a few studies of polonium chemistry have been published, mostly between 1950 and 1990. The recent (2006) event in which (210)Po evidently was used as a poison to kill A. Litvinenko has raised new interest in polonium. 2011 being the 100th anniversary of the Marie Curie Nobel Prize in Chemistry, the aim of this review is to look at the several aspects of polonium linked to its chemical properties and its radiotoxicity, including (i) its radiochemistry and interaction with matter; (ii) its main sources and uses; (iii) its physicochemical properties; (iv) its main analytical methods; (v) its background exposure risk in water, food, and other environmental media; (vi) its biokinetics and distribution following inhalation, ingestion, and wound contamination; (vii) its dosimetry; and (viii) treatments available (decorporation) in case of internal contamination.

    Contamination inside Space Station modules was studied to determine the best methods of controlling contamination. The work was conducted in five tasks that identified existing contamination control requirements, analyzed contamination levels, developed outgassing specification for materials, wrote a contamination control plan, and evaluated current materials of offgassing tests used by NASA. It is concluded that current contamination control methods can be made to function on the Space Station for up to 1000 days, but that current methods are deficient for periods longer than about 1000 days.

    In this review we used the published data on depleted uranium (experimental and epidemiological) from the current literature. Depleted uranium is a toxic heavy metal that in high dose may cause poisoning and health effects as those caused by lead, mercury, and chromium. It is slightly radioactive. The aim of this review was to select, to arrange, to present references of scientific papers, and to summarise the data in order to give a comprehensive image of the results of toxicological studies on depleted uranium that have been done on animals (including carcinogenic activity). We have also used epidemiological posted study results related to occupational and environmental exposure to depleted uranium. The toxicity of uranium has been studied extensively. The results of the studies indicated primarily its chemical toxicity, particularly renal effects, but depleted uranium is not radiological hazard. Uranium is not metal determined to be carcinogenic (the International Agency of Research on Cancer). The military use of depleted uranium will give additional insight into the toxicology of depleted uranium. The present controversy over the radiological and chemical toxicity of depleted uranium used in the Gulf War requests further experimental and clinical investigations of its effects on the biosphere and human beings.

    The International Committee of Medical Journal Editors is a leading independent institution providing guidance for the report of biomedical research and health related topics in medical journals. Established in 1978, it is currently constituted by editors of fourteen general medical journals from different countries, plus one representative for the US National Library of Medicine and one representative for the World Association of Biomedical Journal Editors. Since 1978 the Committee provides a document, originally named "Uniform Requirements…", "to help authors, editors, and others involved in peer review and biomedical publishing create and distribute accurate, clear, unbiased medical journal articles".

    Hayes, J. D.

    1972-01-01

    The feasibility of monitoring volatile contaminants in a large space simulation chamber using techniques of internal reflection spectroscopy was demonstrated analytically and experimentally. The infrared spectral region was selected as the operational spectral range in order to provide unique identification of the contaminants along with sufficient sensitivity to detect trace contaminant concentrations. It was determined theoretically that a monolayer of the contaminants could be detected and identified using optimized experimental procedures. This ability was verified experimentally. Procedures were developed to correct the attenuated total reflectance spectra for thick sample distortion. However, by using two different element designs the need for such correction can be avoided.

    Research collaboration is the way forward in order to improve quality and impact of its research findings. International research collaboration has resulted in international co-authorship in scientific communications and publications. This study highlights the collaborating research and authorship trend in clinical medicine in Malaysia from 2001 to 2010. Malaysian-based author affiliation in the Web of Science (Science Citation Index Expanded) and clinical medicine journals (n = 999) and articles (n = 3951) as of 30th Oct 2011 were downloaded. Types of document analyzed were articles and reviews, and impact factors (IF) in the 2010 Journal Citation Report Science Edition were taken to access the quality of the articles. The number of publications in clinical medicine increased from 4.5 % (n = 178) in 2001 to 23.9 % (n = 944) in 2010. The top three contributors in the subject categories are Pharmacology and Pharmacy (13.9 %), General and Internal Medicine (13.6 %) and Tropical Medicine (7.3 %). By journal tier system: Tier 1 (18.7 %, n = 738), Tier 2 (22.5 %, n = 888), Tier 3 (29.6 %, n = 1170), Tier 4 (27.2 %, n = 1074), and journals without IF (2.1 %, n = 81). University of Malaya was the most productive. Local collaborators accounted for 60.3 % and international collaborations 39.7 %. Articles with international collaborations appeared in journals with higher journal IFs than those without international collaboration. They were also cited more significantly than articles without international collaborations. Citations, impact factor and journal tiers were significantly associated with international collaboration in Malaysia's clinical medicine publications. Malaysia has achieved a significant number of ISI publications in clinical medicine participation in international collaboration.

    The paper addresses the international policies and strategies for the remediation of land contaminated by radioactive material residue, its main aim being to describe the misunderstandings, evolution and status of the international paradigms in this area. Thus, the denotation and connotation of the 'remediation' and 'contamination' concepts are explored, including the ambiguity they produce in understanding of the issues by a sceptical public. Then, the international radiation protection approaches for remediation are portrayed. They derive from the recommendations of the International Commission on Radiological Protection (ICRP), which are described including their basic principles and characterization of exposure situations. Prolonged exposure situations, which are typical in cases of contaminated land, are analysed with particular detail. The newer ICRP general recommendations, as well as recent ICRP recommendations for excluding and exempting exposure situations from regulatory control and for living in long-term contaminated territories after a nuclear accident or a radiation emergency, are examined. Remediation vis-à-vis environmental protection is discussed and the non-technical factors usually involved in decision-making on remediation are examined. Finally, the international safety standards on remediation, which are being established under the aegis of the International Atomic Energy Agency (IAEA), are explored. These include the well established International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources, or BSS, as well as the specific international safety requirements for remediation; a brief overview of the current process of revising the BSS is also included. In its outcome the paper suggests that the time is ripe for a simple and clear international agreement on the levels of radioactivity in territorial contamination with radioactive material that may be considered unambiguously safe.

    Objective This study aimed at describing the profiles of Brazilian and international studies published in orthodontic journals. Methods The sample comprised 635 articles selected from two scientific journals, i.e., Dental Press Journal of Orthodontics and American Journal of Orthodontics and Dentofacial Orthopedics, which were analyzed at three different intervals over a 10-year period (1999 - 2004 - 2009). Articles were described in terms of knowledge domain, study design, and country of origin (or state of origin for Brazilian papers). Results The most frequent study designs adopted in international studies were cohort (23.9%) and cross-sectional (21.7%) designs. Among Brazilian papers, cross-sectional studies (28.9%) and literature reviews (24.6%) showed greater frequency. The topics most often investigated were dental materials (17%) and treatment devices (12.4%) in international articles, with the latter topic being addressed by 16% of the Brazilian publications, followed by malocclusion, with 12.6%. In all cases, the most frequent countries of origin coincided with the countries of origin of each journal. Conclusions The majority of the studies analyzed featured a low level of scientific evidence. Moreover, the findings showed that journals tend to publish studies produced in their own country of origin, and that there are marked discrepancies in the number of papers published by different Brazilian states.

    In international reviews of psychiatric inpatient violence, one study of all types of patient violence found hostility, involuntary admission, and longer hospital stays associated with violence. A second study of comparison-group papers of patient assaults found younger males with schizophrenia, past violence, and substance abuse assaultive. The present review of raw assault data studies assessed characteristics of assaultive patients worldwide. It was hypothesized that patients with schizophrenia would present greatest assault risk. There were three analyses: International/no American studies (reviewed earlier), European studies, and merged International/American studies. Results revealed that male and female patients with schizophrenia, affective disorders, personality disorders, and other diagnoses presented greatest worldwide risk. Results partially support earlier findings. Given that individual institutional studies in this review reported significant assailant characteristics, a second finding is the absence of most of these institutional characteristics in this international review. Possible explanations for findings and a detailed methodological review are presented.

    The primary goal of the International Mussel Watch is to ascertain and assess the levels of chlorinated hydrocarbon pesticide (CHP) and polychlorinated biphenyls (PCB) in bivalves collected from coastal marine waters throughout the world. Increased use of these persistent toxic biocides may result in contamination of living coastal resources from whole ecosystems to specific food resources with consequent implication for human health and the integrity of marine communities. Another goal for the International Mussel Watch Project will be to help develop a sustainable activity for observation and monitoring chemical contamination in especially susceptible regions of the world's oceans.

    Between Dec. 4, 1973, and Feb. 15, 1974, 80 cases of infection due to Salmonella eastbourne, previously a rare isolated serotype in the United States, were reported from twenty-three States. An additional 39 cases were reported from seven Provinces in Canada during a similar period. A telephone case-control study implicated Christmas-wrapped chocolate balls manufactured by a Canadian company as the vehicle of transmission. S. eastbourne was subsequently isolated from several samples of leftover chocolate balls obtained from homes where cases occurred. Investigation of the factory revealed that the contaminated Christmas and Easter chocolates, and a few chocolate items for year-round sale, had been produced between May and October, 1973. Bacteriological testing of samples taken at the plant implicated cocoa beans as the probable source of the salmonella organisms which, in the low-moisture chocolate, were able to survive heating during production. This outbreak and the finding of salmonella of other serotypes in chocolates produced by another manufacturer suggest that chocolate-related salmonellosis may be a significant public-health problem.

    Identifying new practice-changing articles is challenging. To determine the 2015 practice-changing articles most relevant to outpatient general internal medicine, 3 internists independently reviewed the titles and abstracts of original articles, synopses of single studies and syntheses, and databases of syntheses. For original articles, internal medicine journals with the 7 highest impact factors were reviewed: New England Journal of Medicine, Lancet, Journal of the American Medical Association (JAMA), British Medical Journal, Public Library of Science Medicine, Annals of Internal Medicine, and JAMA Internal Medicine. For synopses of single studies and syntheses, collections in American College of Physicians Journal Club, Journal Watch, and Evidence-Based Medicine were reviewed. For databases of synthesis, Evidence Updates and the Cochrane Library were reviewed. More than 100 articles were identified. Criteria for inclusion were as follows: clinical relevance, potential for practice change, and strength of evidence. Clusters of important articles around one topic were considered as a single-candidate series. The 5 authors used a modified Delphi method to reach consensus on inclusion of 7 topics for in-depth appraisal.

    The International Space Station (ISS) is an on-orbit platform for science utilization in low Earth orbit with multiple sites for external payloads with exposure to the natural and induced environments. Contamination is one of the induced environments that can impact performance, mission success and science utilization on the vehicle. This paper describes the external contamination control requirements and integration process for externally mounted payloads on the ISS. The external contamination control requirements are summarized and a description of the integration and verification process is detailed to guide payload developers in the certification process of attached payloads on the vehicle. A description of the required data certification deliverables covers the characterization of contamination sources. Such characterization includes identification, usage and operational data for each class of contamination source. Classes of external contamination sources covered are vacuum exposed materials, sources of leakage, vacuum venting and thrusters. ISS system level analyses are conducted by the ISS Space Environments Team to certify compliance with external contamination control requirements. This paper also addresses the ISS induced contamination environment at attached payload sites, both at the requirements level as well as measurements made on ISS.

    Novel methods and associated tools permitting individual identification in publicly accessible SNP databases have become a debatable issue. There is growing concern that current technical and ethical safeguards to protect the identities of donors could be insufficient. In the context of human embryonic stem cell research, there are no studies focusing on the probability that an hESC line donor could be identified by analyzing published SNP profiles and associated genotypic and phenotypic information. We present the International Stem Cell Forum (ISCF) Ethics Working Party's Policy Statement on "Publishing SNP Genotypes of Human Embryonic Stem Cell Lines (hESC)". The Statement prospectively addresses issues surrounding the publication of genotypic data and associated annotations of hESC lines in open access databases. It proposes a balanced approach between the goals of open science and data sharing with the respect for fundamental bioethical principles (autonomy, privacy, beneficence, justice and research merit and integrity).

  12. Discriminating Gene Expression Signature of Radiation-Induced Thyroid Tumors after Either External Exposure or Internal Contamination

    Both external radiation exposure and internal radionuclide contamination are well known risk factors in the development of thyroid epithelial tumors. The identification of specific molecular markers deregulated in radiation-induced thyroid tumors is important for the etiological diagnosis since neither histological features nor genetic alterations can discriminate between sporadic and radiation-induced tumors. Identification of highly discriminating markers in radiation-induced tumors is challenging as it relies on the ability to identify marker deregulation which is associated with a cellular stress that occurred many years before in the thyroid cells. The existence of such a signature is still controversial, as it was not found in several studies while a highly discriminating signature was found in both post-radiotherapy and post-Chernobyl series in other studies. Overall, published studies searching for radiation-induced thyroid tumor specificities, using transcriptomic, proteomic and comparative genomic hybridization approaches, and bearing in mind the analytical constraints required to analyze such small series of tumors, suggest that such a molecular signature could be found. In comparison with sporadic tumors, we highlight molecular similarities and specificities in tumors occurring after high-dose external radiation exposure, such as radiotherapy, and in post-Chernobyl tumors that occurred after internal 131I contamination. We discuss the relevance of signature extrapolation from series of tumors developing after high and low doses in the identification of tumors induced at very low doses of radiation. PMID:24704841

    This paper documents International Space Station (ISS) external contamination observations and surface assessments covering Flights 1A/R through 6A. These observations are based on imaging from ISS missions, as active external contamination monitoring is not present in the configuration at this time. Imaging from ISS missions is a critical resource as it records the condition of ISS surfaces and helps identify visible signs of surface degradation. The observations are divided into three main sections; the first section covers the Functional Cargo Block (FGB - Russian Segment), the second section covers the Service Module (SM - Russian Segment), and the third section covers the U.S. Segment (Node 1 and Primary Mating Adapters 1 and 2). This distinction is important as materials selection, design and contamination control procedures differ between the FGB and Service Module on the Russian Segment and the U.S. Segment. Numerous observations of FGB self-contamination have been made through ISS imaging obtained during Shuttle flights. These observations were not surprising as external contamination studies conducted during the Shuttle-Mir (Phase I) Program showed extensive contamination induced by the Russian hardware. The impact of FGB induced contamination on ISS sensitive surfaces was mitigated due to FGB on-orbit time vacuum baking the Russian hardware prior to the deployment of ISS contamination sensitive hardware. Service Module impacts on ISS hardware were mitigated with a combination of changes in materials selection and on-orbit vacuum baking as there would be less on-orbit time before deployment of sensitive surfaces. While changes were made to materials selection, self-contamination observations have also been made on the Service Module. At this point, the U.S. Segment appears to be largely free of self-induced contamination. This confirms predictions made during the design and integration phase.

    To help young scientists succeed in our field we should not only model scientific methods and inquiry, but also train them in the art of scientific writing - after all, poorly written proposals, reports or journal articles can be a show stopper for any researcher. Research internships are an effective place to provide such training, because they offer a unique opportunity to integrate writing with the process of conducting original research. This presentation will describe how scientific communication is integrated into the SOARS program. Significant Opportunities in Atmospheric Research and Science (SOARS) is an undergraduate-to graduate bridge program that broadens participation in the geosciences. SOARS aims to foster the next generation of leaders in the atmospheric and related sciences by helping students develop investigative expertise complemented by leadership and communication skills. Each summer, interns (called protégés) attend a weekly seminar designed to help them learn scientific writing and communication skills. The workshop is organized around the sections of a scientific paper. Workshop topics include reading and citing scientific literature, writing an introduction, preparing a compelling abstract, discussing results, designing effective figures, and writing illuminating conclusions. In addition, protégés develop the skills required to communicate their research to both scientists and non-scientists through the use of posters, presentations and informal 'elevator' speeches. Writing and communication mentors guide protégés in applying the ideas from the workshop to the protégés' required summer scientific paper, poster and presentation, while a strong peer-review component of the program gives the protégés a taste of analyzing, critiquing and collaborating within a scientific forum. This presentation will provide practical tips and lessons learned from over ten years of scientific communications workshops within the SOARS program

    The aim of this work was to develop a computational tool that integrates several statistical analysis features for biodistribution data from internal contamination experiments. These data represent actinide levels in biological compartments as a function of time and are derived from activity measurements in tissues and excreta. These experiments aim at assessing the influence of different contamination conditions (e.g. intake route or radioelement) on the biological behavior of the contaminant. The ever increasing number of datasets and diversity of experimental conditions make the handling and analysis of biodistribution data difficult. This work sought to facilitate the statistical analysis of a large number of datasets and the comparison of results from diverse experimental conditions. Functional modules were developed using the open-source programming language R to facilitate specific operations: descriptive statistics, visual comparison, curve fitting, and implementation of biokinetic models. In addition, the structure of the datasets was harmonized using the same table format. Analysis outputs can be written in text files and updated data can be written in the consistent table format. Hence, a data repository is built progressively, which is essential for the optimal use of animal data. Graphical representations can be automatically generated and saved as image files. The resulting computational tool was applied using data derived from wound contamination experiments conducted under different conditions. In facilitating biodistribution data handling and statistical analyses, this computational tool ensures faster analyses and a better reproducibility compared with the use of multiple office software applications. Furthermore, re-analysis of archival data and comparison of data from different sources is made much easier. Hence this tool will help to understand better the influence of contamination characteristics on actinide biokinetics. Our approach can aid

    The aim of this research was to evaluate bacterial contamination along the implant-abutment interface in relation to the size of the interface. 80 brand name implants were used, 40 internal-hex and 40 external-hex. The implants were handled in a sterile atmosphere inside a box, where they were inoculated with 0.3 μl of the Streptococcus sanguis ATCC10556 bacterium in the interior and the abutment was immediately installed with a torque of 30 Ncm for the external-hex and 20 Ncm for the internal-hex; the system was included in an Eppendorf control for 30 seconds and then placed in an Eppendorf control for 30 days. The implants were removed and assessed under a scanning electron microscope while the Eppendorf controls were bred in blood agar to analyze the colonies formed. The data were analyzed using the Chi-squared, Kruskal-Wallis and Mann-Whitney tests, considering a value of p<0.05 to obtain statistical significance. Five implants were excluded due to probable external contamination. Microspaces of up to 86.8 μm were observed in the external-hex implants and up to 53.9 μm in the internal-hex implants with no significant differences between the different systems being observed (p>0.05). The contamination observed was produced mainly in the external-hex implants and statistically significant differences were observed between the different hex systems from the same company. No significant differences were observed between interface size and bacterial contamination. Within our limitations, there was no relation between the size of the implant-abutment interface and bacterial contamination with Streptococcus sanguis ATCC10556. PMID:24753751

    Trace contaminant control onboard the International Space Station will be accomplished not only by the Trace Contaminant Control Subassembly but also by other Environmental Control and Life Support System subassemblies. These additional removal routes include absorption by humidity condensate in the Temperature and Humidity Control Condensing Heat Exchanger and adsorption by the Carbon Dioxide Removal Assembly. The Trace Contaminant Injection Test, which was performed at NASA's Marshall Space Flight Center, investigated the system-level removal of trace contaminants by the International Space Station Atmosphere Revitalization, and Temperature/Humidity Control Subsystems, (November-December 1997). It is a follow-on to the Integrated Atmosphere Revitalization Test conducted in 1996. An estimate for the magnitude of the assisting role provided by the Carbon Dioxide Removal Assembly and the Temperature and Humidity Control unit was obtained. In addition, data on the purity of Carbon Dioxide Removal Assembly carbon dioxide product were obtained to support Environmental Control and Life Support System Air Revitalization Subsystem loop closure.

    Fenner-Crisp, Penelope A

    2012-12-01

    Contaminants are undesirable constituents in food. They may be formed during production of a processed food, present as a component in a source material, deliberately added to substitute for the proper substance, or the consequence of poor food-handling practices. Contaminants may be chemicals or pathogens. Chemicals generally degrade over time and become of less concern as a health threat. Pathogens have the ability to multiply, potentially resulting in an increased threat level. Formal structures have been lacking for systematically generating and evaluating hazard and exposure data for bioactive agents when problem situations arise. We need to know what the potential risk may be to determine whether intervention to reduce or eliminate contact with the contaminant is warranted. We need tools to aid us in assembling and assessing all available relevant information in an expeditious and scientifically sound manner. One such tool is the International Life Sciences Institute (ILSI) Key Events Dose-Response Framework (KEDRF). Developed as an extension of the WHO's International Program on Chemical Safety/ILSI mode of action/human relevance framework, it allows risk assessors to understand not only how a contaminant exerts its toxicity but also the dose response(s) for each key event and the ultimate outcome, including whether a threshold exists. This presentation will illustrate use of the KEDRF with case studies included in its development (chloroform and Listeriaonocytogenes) after its publication in the peer-reviewed scientific literature (chromium VI) and in a work in progress (3-monochloro-1, 2-propanediol).

    UNESCO's Intergovernmental Oceanographic Commission published (1982), in cooperation with ICSEM, a new International Bathymetric Chart of the Mediterranean (10 sheets, scale 1:1,000,000). Almost 80% of the data were derived from the systematic survey of the Mediterranean performed by O.G.S., initially in cooperation with the La Spezia Saclant Centre (1961-1965; 112,000 km of tracks), subsequently for the CNR's first oceanographic program (1965-1972; 217,500 km of tracks). The area east to 26{degree}20'E has been completed by Cambridge University. The main technical specifications in the performance and the principal geologic and geophysical deductions will be outlined. It will follow a description of the cartographic preparation and realization. The feasibility studies were initiated for the following maps: gravity anomalies, aeromagnetism, seismicity, Holocene sedimentation, and the Pliocene-Quaternary.

    Applied Kinesiology (AK) is a diagnostic and therapeutic approach used by a large number of chiropractors. AK seminars are conducted worldwide; during these seminars mention is frequently made of the presence of supportive research. A review was undertaken of the type and scientific quality of 50 papers which had been published between 1981 and 1987 by the International College of Applied Kinesiology, 20 of which were classified as research papers. These were subjected to further scrutiny relating to criteria considered crucial in research methodology, namely, a clear identification of sample size, inclusion criteria, blind and naive subjects and statistical analysis. Although some papers satisfied several of these criteria, none satisfied all seven of them. As none of the papers included adequate statistical analyses, no valid conclusions could be drawn concerning their report of findings.

    A brief description is provided of the basic concepts related to 'internal dose' and how it differs from doses that result from radioactive materials and direct radiation outside of the body. The principles of radiation dose reconstruction, as applied to both internal and external doses, is discussed based upon a recent publication prepared by the US National Council on Radiation Protection and Measurements. Finally, ideas are introduced related to residual radioactive contamination in the environment that has resulted from the releases from the damaged reactors and also to the management of wastes that may be generated in both regional cleanup and NPP decommissioning.

    Chronic internal radiation contamination accounts for a substantial fraction of long-term cumulative radiation exposure among residents in radiation-contaminated areas. However, little information is available on ongoing chronic internal radiation contamination among residents near the crippled Fukushima Daiichi nuclear power plant. Using a whole body counter, internal radiation contamination levels among elementary and middle school students who commute to 22 schools located within Minamisoma city were assessed between May and July 2013 (26 to 28 mo after the disaster). Of 3,299 elementary and middle school students in the city, 3,255 individuals (98%) were screened through school health check-ups. Not a single student was detected with internal radiation contamination due to radioactive cesium. The study found no risk of chronic internal radiation exposure among residents near the crippled nuclear power plant. Current food inspection by local governments, volunteers, and farmers has been functioning well within Fukushima prefecture. However, food management by screening suspected contamination along with whole body counter screening are key public health interventions and should be continued to avoid further internal radiation exposure in radiation-contaminated areas.

The TCCS employs expendable adsorbent beds to accomplish its function leading to a potentially signi.cant life cycle cost over the life of the ISS. Because maintaining the TCCSs proper can be logistically intensive, its performance in .ight has been studied in detail to determine where savings may be achieved. Details of these studies and recommendations for improving the TCCS s process economics without compromising its performance or crew health and safety are presented and discussed.

    Following a radioactive dispersal device (RDD) incident, it may be necessary to evaluate the internal contamination levels of a large number of potentially affected individuals to determine if immediate medical follow-up is necessary. Since the current laboratory capacity to screen for internal contamination is limited, rapid field screening methods can be useful in prioritizing individuals. This study evaluated the suitability of a radiation portal monitor for such screening. A model of the portal monitor was created for use with models of six anthropomorphic phantoms in Monte Carlo N-Particle Transport Code Version 5 (MCNP) X-5 Monte Carlo Team (MCNP A General Monte Carlo N-Particle Transport Code Version 5. LA-CP-03-0245. Vol. 2. Los Alamos National Laboratory, 2004.). The count rates of the portal monitor were simulated for inhalation and ingestion of likely radionuclides from an RDD for each of the phantoms. The time-dependant organ concentrations of the radionuclides were determined using Dose and Risk Calculation Software Eckerman, Leggett, Cristy, Nelson, Ryman, Sjoreen and Ward (Dose and Risk Calculation Software Ver. 8.4. ORNL/TM-2001/190. Oak Ridge National Laboratory, 2006.). Portal monitor count rates corresponding to a committed effective dose E(50) of 10 mSv are reported.

    To evaluate the efficacy of a novel attenuated Salmonella Enteritidis (△lon△cpxR) vaccine candidate (JOL919), chickens were immunized through oral and intramuscular routes to reduce egg contamination against S. Enteritidis challenge. Birds were orally immunized with JOL919 on the first day of life and were subsequently boosted in the 6th and 16th weeks through oral (group B) or intramuscular (group C) route, while control birds were unimmunized (group A). The chickens of all groups were challenged intravenously with the virulent S. Enteritidis strain in the 24th week. The immunized groups B and C showed significantly higher plasma IgG and intestinal secretory IgA levels as compared to those of the control group. The lymphocyte proliferation response and CD45(+) CD3(+) T-cell number in the peripheral blood of the groups B and C were significantly increased. In addition, the egg contamination rates were significantly lower in the group B (0%, 10.7% and 0%) and the group C (3.6%, 14.3% and 3.6%) as compared to the group A (28.6%, 42.8% and 28.6%) in the 1st, 2nd and 3rd weeks post-challenge. All animals in the groups B and C showed lower organ lesion scores in the liver and spleen and lower bacterial counts in the liver, spleen and ovary at the 3rd week post-challenge. These results indicate that this vaccine candidate can be an efficient tool for prevention of Salmonella infections by inducing protective humoral and cellular immune responses. In addition, this vaccine did not prevent egg contamination, but did appear to reduce incidence. Booster immunizations, especially via oral administration route, showed an efficient protection against internal egg contamination with S. Enteritidis.

    With increasing outbreaks of gastroenteritis associated with produce, it is important to assess interventions to reduce the risk of illness. UV, ozone and high pressure are non-thermal processing technologies that have potential to inactivate human pathogens on produce and allow the retention of fresh-like organoleptic properties. The objective of this study was to determine if UV, ozone, and high pressure are effective technologies compared to traditional chlorine spray on green onions to reduce enteric viral pathogens and to determine the effect of location of the virus (surface or internalized) on the efficacy of these processes. Mature green onion plants were inoculated with murine norovirus (MNV), hepatitis A virus (HAV) and human adenovirus type 41 (Ad41) either on the surface through spot inoculation or through inoculating contaminated hydroponic solution allowing for uptake of the virus into the internal tissues. Inoculated green onions were treated with UV (240 mJ s/cm(2)), ozone (6.25 ppm for 10 min), pressure (500 MPa, for 5 min at 20°C), or sprayed with calcium hypochlorite (150 ppm, 4°C). Viral inactivation was determined by comparing treated and untreated inoculated plants using cell culture infectivity assays. Processing treatments were observed to greatly affect viral inactivation. Viral inactivation for all three viruses was greatest after pressure treatment and the lowest inactivation was observed after chlorine and UV treatment. Both surface inoculated viruses and viruses internalized in green onions were inactivated to some extent by these post-harvest processing treatments. These results suggest that ozone and high pressure processes aimed to reduce the level of microbial contamination of produce have the ability to inactivate viruses if they become localized in the interior portions of produce.

    Outgassing, deposition, and desorption kinetics of silicone compounds, are examined as examples of optical surface contaminants of spacecraft windows. Their behavior in a space environment after exposure to ultraviolet radiation is also examined. The use of internal reflection spectroscopy is shown to provide a viable means of real-time, in-situ identification of contaminants of orbiting spacecraft. The instrumental techniques are proposed as the basis of further investigations and the development of flight hardware.

    During routine screening in 2011, US Customs and Border Protection (CBP) identified 2 persons with elevated radioactivity. CBP, in collaboration with Los Alamos National Laboratory, informed the Food and Drug Administration (FDA) that these people could have increased radiation exposure as a result of undergoing cardiac Positron Emission Tomography (PET) scans several months earlier with rubidium Rb 82 chloride injection from CardioGen-82. We conducted a multistate investigation to assess the potential extent and magnitude of radioactive strontium overexposure among patients who had undergone Rb 82 PET scans. We selected a convenience sample of clinical sites in 4 states and reviewed records to identify eligible study participants, defined as people who had had an Rb 82 PET scan between February and July 2011. All participants received direct radiation screening using a radioisotope identifier able to detect the gamma energy specific for strontium-85 (514 keV) and urine bioassay for excreted radioactive strontium. We referred a subset of participants with direct radiation screening counts above background readings for whole body counting (WBC) using a rank ordering of direct radiation screening. The rank order list, from highest to lowest, was used to contact and offer voluntary enrollment for WBC. Of 308 participants, 292 (95%) had direct radiation screening results indistinguishable from background radiation measurements; 261 of 265 (98%) participants with sufficient urine for analysis had radioactive strontium results below minimum detectable activity. None of the 23 participants who underwent WBC demonstrated elevated strontium activity above levels associated with routine use of the rubidium Rb 82 generator. Among investigation participants, we did not identify evidence of strontium internal contamination above permissible levels. This investigation might serve as a model for future investigations of radioactive internal contamination incidents.

  11. Individual monitoring for internal contamination with plutonium compounds at JAEA-NCL.

    2011-07-01

    This paper provides an outline of an individual monitoring programme for internal contamination with Pu compounds and some of the knowledge obtained from experience of inhalation incidents that occurred over the past few decades at the Japan Atomic Energy Agency, Nuclear Fuel Cycle Engineering Laboratories (JAEA-NCL). Most of the incidents resulted in minor exposure doses, being an average of 0.1 mSv at a mixed oxide plant and 1.5 mSv at a reprocessing plant. Only two incidents involving three workers resulted in exposure over the regulatory dose limits of that time. The maximum exposure dose, an effective dose equivalent of 90 mSv, was assessed for a worker involved in the incident that took place at the reprocessing plant in 1993. Only faecal measurements have been used in final dose assessments because alternative monitoring data have rarely been available. Further investigations on the physicochemical properties specific to Pu compounds in workplaces have therefore been needed to improve not only the accuracy of internal dose assessments but also the nasal swab method useful in deciding medical intervention.

    This paper has briefly analyzed the publication status of Chinese stomatology papers in 2009 with statistics from Journal Citation Reports® provided by Thomson Scientific. Only those papers with the first author coming from the mainland of China were included for calculations. We have found a significant increase in the number of SCIE-indexed papers, most of which were published by six dental institutions in China. Among all Chinese medical institutions, West China School of Stomatology Sichuan University is the first dental institution to enter the top-20 list with the most publications, and it also ranks the 9th in the number of outstanding articles. West China School of Stomatology Sichuan University and the Forth Military Medical University are the only two dental institutions in China which have published SCIE-indexed papers over a hundred. The former has published the most SCIE-indexed stomatology papers, while the latter has the highest average impact factor. As the laboratories and funds in China have close connections with various dental hospitals, the pratice of translational medicine in dentistry is fast and fluent. PMID:21449209

    1983-02-01

    Following DiStefano and also Williams and Woods we have used scanning internal photoemission to map barrier inhomogeneities in sodium-contaminated Al/SiO2/Si Metal-Oxide-Semiconductor capacitors. A computer controlled system was used with a He/Cd laser. A well-known and striking result of the previous work is that peaks tend to be found in the internal photoemission. In some cases these peaks have been attributed to the segregation of an initially uniform sodium ion distribution into clusters of a few μm diameter. This clustering occurred during a low temperature anneal under positive gate bias. The mechanism for the supposed segregation is of considerable interest. One possibility is that the segregation maps pre-existing inhomogeneities either in the silicon substrate or in the oxide. Another mechanism, proposed by Williams and Woods, involves the image force lowering of the potential energy of the sodium ions. The lowering is increased as the induced electron charge density in the silicon increases with progressive clustering. This positive feedback was proposed to lead to instability. A thermodynamic development of the model by Wojtowcz led to the concept of two-dimensional phase transitions in the sodium distribution. In the present work we report the result that peaks can be produced by a low temperature anneal with the sodium either at the Al/SiO2 interface or drifted to the Si/SiO2 interface. In the first case, the sodium must be drifted to the silicon side before the peaks appear. This may show that nucleation centers are produced by the anneal and mapped by the sodium. Alternatively, if un-nucleated segregation occurs it must be a function of sodium in SiO2 rather than of sodium near the Si/SiO2 interface. Correlation with weak spot breakdown was again observed and the effects of using HCl oxides were studied.

    Ten creosote-exposed workers of a wood impregnation plant participated in this study, which took place in two consecutive weeks on a Monday, after a weekend off. On one of the two days each worker wore Tyvek coveralls underneath his normal workclothes. Dermal contamination measurements (pyrene on exposure pads) and biological monitoring (urinary 1-OH-pyrene) were performed to measure the reduction of both the skin contamination and the internal dose. The total pyrene skin contamination of workers not wearing coveralls ranged between 47 and 1510 micrograms.d-1 (0.2-7.5 mumol.d-1). On the average, the coveralls reduced the pyrene contamination on the workers' skin by about 35 (SD 63)%. The excreted amount of 1-OH-pyrene in urine decreased significantly from 6.6 to 3.2 micrograms (30.2 to 14.7 nmol). Multiple regression analysis showed that skin contamination by polycyclic aromatic hydrocarbons is the main determinant of the internal exposure dose of creosote workers.

    As part of the International Space Station (ISS) Trace Contaminant Control Subassembly (TCCS) development, a performance test has been conducted to provide reference data for flight verification analyses. This test, which used the U.S. Habitation Module (U.S. Hab) TCCS as the test article, was designed to add to the existing database on TCCS performance. Included in this database are results obtained during ISS development testing; testing of functionally similar TCCS prototype units; and bench scale testing of activated charcoal, oxidation catalyst, and granular lithium hydroxide (LiOH). The present database has served as the basis for the development and validation of a computerized TCCS process simulation model. This model serves as the primary means for verifying the ISS TCCS performance. In order to mitigate risk associated with this verification approach, the U.S. Hab TCCS performance test provides an additional set of data which serve to anchor both the process model and previously-obtained development test data to flight hardware performance. The following discussion provides relevant background followed by a summary of the test hardware, objectives, requirements, and facilities. Facility and test article performance during the test is summarized, test results are presented, and the TCCS's performance relative to past test experience is discussed. Performance predictions made with the TCCS process model are compared with the U.S. Hab TCCS test results to demonstrate its validation.

    The Nuclear Age began in 1945 with testing in New Mexico, USA, and the subsequent bombings of Hiroshima and Nagasaki. Regardless of attempts to limit the development of nuclear weapons, the current world arsenal has reached the staggering dimensions and presents a significant concern for the biosphere and mankind. In an explosion of a nuclear weapon, over 400 radioactive isotopes are released into the biosphere, 40 of which pose potential dangers including iodine, cesium, alkaline earths, and actinides. The immediate health effects of nuclear explosions include thermal, mechanical, and acute radiation syndrome. Long-term effects include radioactive fallout, internal contamination, and long-term genotoxicity. The current controversial concern over depleted uranium's somatic and genetic toxicity is still a subject of worldwide sustained research. The host of data generated in the past decades has demonstrated conflicting findings, with the most recent evidence showing that its genotoxicity is greater than previously considered. Of particular concern are the osteotropic properties of uranium isotopes due to their final retention in the crystals of exchangeable and nonexchangeable bone as well as their proximity to pluripotent stem cells. Depleted uranium remains an unresolved issue in both warfare and the search for alternative energy sources.

    Hexane is a toxic volatile organic compound that is quite abundant in gas emissions from chemical industries and printing press and painting centers, and it is necessary to treat these airstreams before they discharge into the atmosphere. This article presents a treatment for hexane-contaminated air in steady-state conditions using an internal-loop airlift bioreactor inoculated with a Pseudomonas aeruginosa strain. Bioprocesses were conducted at 20-mL/min, a load of 1.26 gm3 of C6H14, and a temperature of 28 degrees C. The results of hexane removal efficiencies were presented as a function of the inoculum size (approx 0.07 and 0.2 g/L) and cell reuse. Bioprocess monitoring comprises quantification of the biomass, the surface tension of the medium, and the hexane concentration in the fermentation medium as well as in the inlet and outlet airstreams. The steady-state results suggest that the variation in inoculum size from 0.07 to 0.2 g/L promotes hexane abatement from the influent from 65 to 85%, respectively. Total hydrocarbon removal from the waste gas was achieved during experiments conducted using reused cells at an initial microbial concentration of 0.2 g/L.

    The current dual-membrane gas trap is designed to remove non-condensed gas bubbles from the Internal Thermal Control System (ITCS) coolant on board the International Space Station (ISS). To date it has successfully served its purpose of preventing gas bubbles from causing depriming, overspeed, and shutdown of the ITCS pump. However, contamination in the ITCS coolant has adversely affected the gas venting rate and lifetime of the gas trap, warranting a development effort for a next-generation gas trap. Previous testing has shown that a hydrophobic-only design is capable of performing even better than the current dual-membrane design for both steady-state gas removal and gas slug removal in clean deionized water. This paper presents results of testing to evaluate the effects of surfactant contamination on the steady-state performance of the hydrophobic-only design.

    Background: The Fukushima Dai-ichi nuclear disaster, the first level-7 major nuclear disaster since Chernobyl, raised concerns about the future health consequences of exposure to and intake of radionuclides. Factors determining the risk and level of internal radiation contamination after a nuclear accident, which are a key to understanding and improving current nuclear disaster management, are not well studied. Objective: We investigated both the prevalence and level of internal contamination in residents of Minamisoma, and identified factors determining the risk and levels of contamination. Methods: We implemented a program assessing internal radiation contamination using a whole body counter (WBC) measurement and a questionnaire survey in Minamisoma, between October 2011 and March 2012. Results: Approximately 20% of the city’s population (8,829 individuals) participated in the WBC measurement for internal contamination, of which 94% responded to the questionnaire. The proportion of participants with detectable internal contamination was 40% in adults and 9% in children. The level of internal contamination ranged from 2.3 to 196.5 Bq/kg (median, 11.3 Bq/kg). Tobit regression analysis identified two main risk factors: more time spent outdoors, and intake of potentially contaminated foods and water. Conclusions: Our findings suggest that, with sensible and reasonable precautions, people may be able to live continuously in radiation-affected areas with limited contamination risk. To enable this, nuclear disaster response should strictly enforce food and water controls and disseminate evidence-based and up-to-date information about avoidable contamination risks.

    Oysters from 16 sites in Tampa Bay, Florida, were collected during a 6-week period in winter 1993 and analyzed for both biological characteristics and tissue chemical concentrations. Using previous sediment contamination and toxicity data, oyster tissues from the selected sites were expected to exhibit a wide range in both quantity and type of chemicals. Chemical analysis showed tissue concentrations at some of these sites to be greater than national averages, as reported by the National Status and Trends Mussel Watch Program, for total PAH, total PCB, total chlordanes, DDT, Cu, Pb and Zn. Measures of oyster internal defense, including hemocyte density, rate of locomotion and superoxide generation, varied significantly among sites and were generally higher at sites with higher tissue concentrations of xenobiotic chemicals. Potential associations between oyster defense characteristics and accumulated chemical contaminants, either singly or in chemical classes, were explored using correlation analysis and a composited ranking procedure. Positive relationships were found for hemocyte characteristics with certain trace metal (Cu, Sn and Zn) and PAH analytes, whereas negative relationships were found with certain PCB and pesticide analytes. Heightened defenses in contaminated conditions may reflect a hemocyte process for sequestration and detoxification of environmental contaminants. Oysters from four of the 16 sites were additionally collected in June and September 1993 and site-related differences did not closely parallel those obtained in winter. Seasonal environmental factors may have altered contaminant-related differences among sites.

    Maintaining low levels of chronic internal contamination among residents in radiation-contaminated areas after a nuclear disaster is a great public health concern. However, the efficacy of reduction measures for individual internal contamination remains unknown. To reduce high levels of internal radiation exposure in a group of individuals exposed through environmental sources, we performed careful dietary intervention with identification of suspected contaminated foods, as part of mass voluntary radiation contamination screenings and counseling program in Minamisoma Municipal General Hospital and Hirata Central Hospital. From a total of 30,622 study participants, only 9 residents displayed internal cesium-137 (Cs-137) levels of more than 50 Bq/kg. The median level of internal Cs-137 contamination in these residents at the initial screening was 4,830 Bq/body (range: 2,130–15,918 Bq/body) and 69.6 Bq/kg (range: 50.7–216.3 Bq/kg). All these residents with high levels of internal contamination consumed homegrown produce without radiation inspection, and often collected mushrooms in the wild or cultivated them on bed-logs in their homes. They were advised to consume distributed food mainly and to refrain from consuming potentially contaminated foods without radiation inspection and local produces under shipment restrictions such as mushrooms, mountain vegetables, and meat of wild life. A few months after the intervention, re-examination of Cs levels revealed remarkable reduction of internal contamination in all residents. Although the levels of internal radiation exposure appear to be minimal amongst most residents in Fukushima, a subset of the population, who unknowingly consumed highly contaminated foodstuffs, experienced high levels of internal contamination. There seem to be similarities in dietary preferences amongst residents with high internal contamination levels, and intervention based on pre- and post-test counseling and dietary advice from medical care

Group A chickens were used as a non-vaccinated control, group B chickens were immunized with the ghost carrying LTB protein, group C chickens were immunized with the ghost and, group D chickens were immunized with a commercial vaccine. Group D chickens showed the swelling at the injection site, while no adverse reactions were observed at injection sites of the group B and C chickens. Chickens from the immunized groups B, C, and D demonstrated significant increases in plasma IgG, intestinal secretory IgA levels, and antigen-specific lymphocyte proliferative responses. After challenge with a virulent SE strain via intravenous route, groups B, C, and D showed significantly higher egg production and lower internal egg contamination and lower recovery of the challenge strain from internal organs compared to non-immunized-challenged control group A. In conclusion, these data indicate that immunization of chickens with the ghost and ghost carrying LTB is safe, without causing any adverse reaction, and is effective as the commercial vaccine in terms of reduction in internal egg contamination and internal organ colonization of Salmonella.

    Resettlement to their radiation-contaminated hometown could be an option for people displaced at the time of a nuclear disaster; however, little information is available on the safety implications of these resettlement programs. Kawauchi village, located 12-30 km southwest of the Fukushima Daiichi nuclear power plant, was one of the 11 municipalities where mandatory evacuation was ordered by the central government. This village was also the first municipality to organize the return of the villagers. To assess the validity of the Kawauchi villagers' resettlement program, the levels of internal Cesium (Cs) exposures were comparatively measured in returnees, commuters, and non-returnees among the Kawauchi villagers using a whole body counter. Of 149 individuals, 5 villagers had traceable levels of Cs exposure; the median detected level was 333 Bq/body (range, 309-1050 Bq/kg), and 5.3 Bq/kg (range, 5.1-18.2 Bq/kg). Median annual effective doses of villagers with traceable Cs were 1.1 x 10(-2) mSv/y (range, 1.0 x 10(-2)-4.1 x 10(-2) mSv/y). Although returnees had higher chances of consuming locally produced vegetables, Cochran-Mantel-Haenszel test showed that their level of internal radiation exposure was not significantly higher than that in the other 2 groups (p=0.643). The present findings in Kawauchi village imply that it is possible to maintain internal radiation exposure at very low levels even in a highly radiation-contaminated region at the time of a nuclear disaster. Moreover, the risks for internal radiation exposure could be limited with a strict food control intervention after resettlement to the radiation-contaminated village. It is crucial to establish an adequate number of radio-contaminated testing sites within the village, to provide immediate test result feedback to the villagers, and to provide education regarding the importance of re-testing in reducing the risk of high internal radiation exposure.

    It has been proposed that German basic psychology journals should change publication language to English in order to facilitate access to research from German-speaking countries. However, to truly increase the dissemination of German research, it seems crucial to progress towards an internationalization of authors and readers. We applied bibliometric analysis to investigate the impact of the transition to English on the rate of foreign authors publishing in Zeitschrift für Experimentelle Psychologie/Experimental Psychology, as well as possible associated changes in citation patterns. There was an increase in the rate of articles published by foreign authors from 14.6 and 8.7 per cent, respectively, for the last biannual periods as German-language journal, to 52.7 per cent in the first biannual period as English-language journal. Regarding citations patterns, the clearest changes emerged for domestic authors. The results illustrate possible consequences of a transition to English as publication language, and reveal that Experimental Psychology has successfully established certain prerequisites for an increase of the international dissemination of German psychology research.

    The Hong Kong oysters Crassostrea hongkongensis are widely farmed in the estuarine waters of Southern China, but they accumulate Cu and Zn to alarmingly high concentrations in the soft tissues. Health risks of seafood consumption are related to contaminants such as toxic metals which are bioaccessible to humans. In the present study, we investigated the oral bioaccessibility of five toxic metals (Ag, Pb, Cd, Cu and Zn) in contaminated oysters collected from different locations of a large estuary in southern China. In all oysters, total Zn concentration was the highest whereas total Pb concentration was the lowest. Among the five metals, Ag had the lowest oral bioaccessibility (38.9-60.8%), whereas Cu and Zn had the highest bioaccessibility (72.3-93.1%). Significant negative correlation was observed between metal bioaccessibility and metal concentration in the oysters for Ag, Cd, and Cu. We found that the oral bioaccessibility of the five metals was positively correlated with their trophically available metal fraction (TAM) in the oyster tissues, and negatively correlated with metal distribution in the cellular debris. Thus, metal partitioning in the TAM and cellular debris controlled the oral bioaccessibility to humans. Given the dependence of oral bioaccessibility on tissue metal contamination, bioaccessibility needs to be incorporated in the risk assessments of contaminated shellfish.

    A whole-body counter in SÚRO (NRPI) Prague, Czech Republic has been upgraded recently with the goal to enhance its capability of a safe, smooth, accurate and reproducible positioning of detectors for whole- and partial-body counting. The counter is intended especially for counting of low energy gamma emitters in various organs and tissues of the human body. Counting efficiency calibration of a four-detector system installed in the shielded room has been performed by means of physical and voxel phantoms. The consistency of in vivo bioassay data of three internal contamination cases long-term monitored in the Institute is shown.

    Chronic exposure to high LET radiation has been shown to cause liver cancer in humans based on studies of patients who received Thorotrast, a colloidal suspension of thorium dioxide formerly used as a radiological contrast agent, and on studies of Russian nuclear weapons workers exposed to internally ingested plutonium. Risk estimates for these exposures and specific subtypes of liver cancer have not been previously reported. Combining published data with tumor registry data pertinent to the Thorotrast cohorts in Germany, Denmark, Portugal, and Japan and to Russian workers, we generally found significantly elevated risks of three major histologic types of liver tumors: hepatocellular carcinoma (HCC), cholangiocarcinoma (CC), and hemangiosarcoma (HS) for Thorotrast exposures. In contrast, HS was the only liver tumor significantly associated with the lower alpha-particle doses experienced by the Russian workers. Excess cases per 1,000 persons exposed to Thorotrast were similar for the three liver cancer subtypes but lower for plutonium exposure. Odds ratios (OR) of HS and CC for Thorotrast were from 26 to 789 and from 1 to 31 times higher than those for HCC, respectively. ORs of liver cirrhosis for Thorotrast exposure ranged from 2.7 (95% confidence interval (CI): 2.2-3.4) to 6.7 (5.1-8.7).

    Traditionally, the most commonly used source of bibliometric data is the Thomson ISI Web of Knowledge, in particular the (Social) Science Citation Index and the Journal Citation Reports, which provide the yearly Journal Impact Factors. This database used for the evaluation of researchers is not advantageous in the humanities, mainly because books, conference papers, and non-English journals, which are an important part of scientific activity, are not (well) covered. This paper presents the use of an alternative source of data, Google Scholar, and its benefits in calculating citation metrics in the humanities. Because of its broader range of data sources, the use of Google Scholar generally results in more comprehensive citation coverage in the humanities. This presentation compares and analyzes some international case studies with ISI Web of Knowledge and Google Scholar. The fields of economics, geography, social sciences, philosophy, and history are focused on to illustrate the differences of results between these two databases. To search for relevant publications in the Google Scholar database, the use of "Publish or Perish" and of CleanPoP, which the author developed to clean the results, are compared.

    After a review of radiometric reference methods used in radiotoxicology, analytical performance of inductively coupled plasma mass spectrometry (ICP-MS) for the workplace urinary diagnosis of internal contamination by radionuclides are evaluated. A literature review (covering the period from 2000 to 2012) is performed to identify the different applications of ICP-MS in radiotoxicology for urine analysis. The limits of detection are compared to the recommendations of the International commission on radiological protection (ICRP 78: "Individual monitoring for internal exposure of workers"). Except one publication describing the determination of strontium-90 (β emitter), all methods using ICP-MS reported in the literature concern actinides (α emitters). For radionuclides with a radioactive period higher than 10(4) years, limits of detection are most often in compliance with ICRP publication 78 and frequently lower than radiometric methods. ICP-MS allows the specific determination of plutonium-239 + 240 isotopes which cannot be discriminated by α spectrometry. High resolution ICP-MS can also measure uranium isotopic ratios in urine for total uranium concentrations lower than 20 ng/L. The interest of ICP-MS in radiotoxicology concerns essentially the urinary measurement of long radioactive period actinides, particularly for uranium isotope ratio determination and 239 and 240 plutonium isotopes discrimination. Radiometric methods remain the most efficient for the majority of other radionuclides.

    The objective International Mussel Watch is to assess the extent of chemical contamination in the equatorial and subequatorial areas of the southern hemisphere with particular attention to coastal areas of developing countries. The First Phase took place in South America, Central America, the Caribbean and Mexico with particular emphasis on PCBs and chlorinated pesticides in mollusks collected at 76 sites in 1991 to 1992. Samples from some sites were also analyzed for polycyclic aromatic hydrocarbons. Results show that concentrations of these organic chemicals in mollusks were generally lower than in similar samples collected in the NOAA Mussel Watch Project in the United States. Relatively high levels found in urban areas were with the ranges of concentrations found in the United States. The Project included a chemical intercomparison exercise that involved analytical chemists from the Host Countries.

    Hazard analysis critical control point (HACCP) programs have been endorsed and implemented globally to enhance food safety. Our objective was to identify, assess, and summarize or synthesize the published research investigating the effect of HACCP programs on microbial prevalence and concentration on food animal carcasses in abattoirs through primary processing. The results of microbial testing pre- and post-HACCP implementation were reported in only 19 studies, mostly investigating beef (n=13 studies) and pork (n=8 studies) carcasses. In 12 of 13 studies measuring aerobic bacterial counts, reductions were reported on beef (7/8 studies), pork (3/3), poultry (1/1), and sheep (1/1). Significant (p<0.05) reductions in prevalence of Salmonella spp. were reported in studies on pork (2/3 studies) and poultry carcasses (3/3); no significant reductions were reported on beef carcasses (0/8 studies). These trends were confirmed through meta-analysis of these data; however, powerful meta-analysis was precluded because of an overall scarcity of individual studies and significant heterogeneity across studies. Australia reported extensive national data spanning the period from 4 years prior to HACCP implementation to 4 years post-HACCP, indicating reduction in microbial prevalence and concentration on beef carcasses in abattoirs slaughtering beef for export; however, the effect of abattoir changes initiated independent of HACCP could not be excluded. More primary research and access to relevant proprietary data are needed to properly evaluate HACCP program effectiveness using modeling techniques capable of differentiating the effects of HACCP from other concurrent factors.

    In vivo monitoring of low-energy X-ray and gamma-ray emitters has always been a difficult task, primarily because of lack of accuracy and the high detection limits of classical techniques. Various types of PIN diodes (diodes with a large intrinsic zone) were tested in the Radiation Protection Department of the Studie Centrum voor Kernenergie, Centre d'étude de l'Energie Nucléaire (Mol, Belgium) in the measurement of radioactive body burden by direct methods. Current research is oriented toward the use of room-temperature diodes for the detection of low-energy photons escaping the body. In this paper, a new counting technique that involves a portable jacket containing the diodes is described. The system uses silicon diodes and is used out of shielding room in order to be near the contamination. With this method rapid analysis and long counting times are possible, stress is reduced, and medical treatment can be optimized. CdZnTe detectors were also evaluated for this measurement technique but this type of detector is better adapted for counting inside a shielding room. The improvement of the accuracy of the measurement, taking into account the effect of the ribs, is described here, as well the associated electronics necessary for this type of counting.

    Close attention must be given to the effects of dredging and disposal operations on the marine environment. The globally applicable Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention 1972), in conjunction with resolutions adopted there under, provides regulations and guidance regarding sea disposal of dredged material. For this purpose the Dredged Material Assessment Framework developed in 1995 provides advice to decision-makers in the field of management of dredged material, incorporating knowledge and experience gained by Contracting Parties to the Convention on potential environmental impacts of dredging operations. Characterization of dredged material is requested with regard to physical and chemical characteristics, including geochemical parameters, potential routes and previous soils of contaminants in the area, and biological characteristics, including tests to determine acute and chronic toxicity, the potential for bioaccumulation and the potential for tainting aquatic living resources. The results of the physical/chemical/biological characterization will indicate whether the dredged material is suitable for disposal at sea. For material found to be unsuitable for beneficial uses, disposal at sea or disposal on land, disposal management techniques will have to be used to reduce or control impacts to a level that-will not constitute an unacceptable risk to human health, or harm living resources, damage amenities or interfere with legitimate uses of the sea. Disposal management techniques may include burial in the sea floor followed by clean sediment capping, selection of special sites, or methods of containment. The Assessment Framework further includes criteria for selection of sea disposal sites, advice for the conduct of impact assessments, and of post-operational monitoring.

    The accidental or intentional release of plutonium or americium can cause acute and long term adverse health effects if they enter the human body by ingestion, inhalation, or injection. These effects can be prevented by rapid removal of these radionuclides by chelators such as calcium or zinc diethylenetriaminepentaacetate (calcium or zinc DTPA). These compounds have been shown to be efficacious in enhancing the elimination of members of the actinide family particularly plutonium and americium when administered intravenously or by nebulizer. The efficacy and adverse effects profile depend on several factors that include the route of internalization of the actinide, the type, and route time of administration of the chelator, and whether the calcium or zinc salt of DTPA is used. Current and future research efforts should be directed at overcoming limitations associated with the use of these complex drugs by using innovative methods that can enhance their structural and therapeutic properties.

    The quantity of some trace metals of mosquito larvae in Shadegan International Wetland from Iran was evaluated. Water, waterbed sediment, and mosquito larvae samplings were carried out from an urban site in the east of the wetland, using standard methods in December 2011. The identified Culiseta subochrea (Edwards) and Aedes caspius s.l. (Pallas) larvae, water, and waterbed sediment samples were analyzed for As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Pb, and Zn trace metals using standard preparation and isolation procedure. Result showed that the waterbed sediment and Cu. subochrea larvae are polluted with all trace metals investigated except As and Hg. The trace metals bioaccumulated in the Cu. subochrea larvae range from 31.78 at the lowest level for Cr to 3822.7 at the highest level for Cd. In a conclusion, this is the first report confirmed that Cu. subochrea likely used as a bioindicator to trace metal pollution in marine ecosystems in the world, especially wetlands.

    A number of interzonal models have been developed to calculate air flows and pollutant transport mechanisms in both single and multizone buildings. A recent development in multizone air-flow modeling, the COMIS model, has a number of capabilities that go beyond previous models, much as COMIS can be used as either a stand-alone air-flow model with input and output features or as an infiltration module for thermal building simulation programs. COMIS was designed during a 12 month workshop at Lawrence Berkeley National Laboratory (LBNL) in 1988-89. In 1990, the Executive Committee of the International Energy Agency`s Energy Conservation in Buildings and Community Systems program created a working group on multizone air-flow modeling, which continued work on COMIS. The group`s objectives were to study physical phenomena causing air flow and pollutant (e.g., moisture) transport in multizone buildings, develop numerical modules to be integrated in the previously designed multizone air flow modeling system, and evaluate the computer code. The working group supported by nine nations, officially finished in late 1997 with the release of IISiBat/COMIS 3.0, which contains the documented simulation program COMIS, the user interface IISiBat, and reports describing the evaluation exercise.

    After the Chernobyl Nuclear Power Plant accident, the residents living around the Chernobyl were revealed to have been internally exposed to 137Cs through the intake of contaminated local foods. To evaluate the current situation of internal 137Cs exposure and the relationship between the 137Cs soil contamination and internal exposure in residents, we investigated the 137Cs body burden in residents who were living in 10 selected cities from the northern part of the Zhitomir region, Ukraine, and collected soil samples from three family farms and wild forests of each city to measured 137Cs concentrations. The total number of study participants was 36,862, of which 68.9% of them were female. After 2010, the annual effective doses were less than 0.1 mSv in over 90% of the residents. The 137Cs body burden was significantly higher in autumn than other seasons (p < 0.001) and in residents living in more contaminated areas (p < 0.001). We also found a significant correlation between the proportion of residents in each city with an estimated annual exposure dose exceeding 0.1 mSv and 137Cs concentration of soil samples from family farms (r = 0.828, p = 0.003). In conclusion, more than 25 years after the Chernobyl accident, the internal exposure doses to residents living in contaminated areas of northern Ukraine is limited but still related to 137Cs soil contamination. Furthermore, the consumption of local foods is considered to be the cause of internal exposure.

    LBERI, a member of the Medical Countermeasures to Radiologic Threats (MCART) consortium funded by NIAID, was tasked to develop biokinetic models for the distribution of radionuclide threats using the most likely routes of incorporation in both small and large animals. In the present paper, the biokinetics of systemically administered soluble cobalt-60 (60Co) have been examined. Male and female jugular-vein-catheterized (JVC) F344 rats received intravenous (IV) doses of 11.2 kBq of 60CoCl2. The distribution of the radiocobalt was followed for 28 d, with tissue sampling done at 1 and 4 h, and at 1, 2, 4, 8, 16, and 28 d. Urine and feces were collected daily. Tissues and excreta were analyzed by gamma pulse height analysis. Within 8d, 93% of the cobalt was eliminated from the body primarily though urine. The highest tissue burdens were found in liver, gastrointestinal (GI) tract, and muscle shortly after administration. These tissues cleared quickly so that by the conclusion of the 28-d study, less than 3% of the recovered dose remained in the body. The results are comparable to published literature values for tissue content of 60Co and for excretion patterns up to 30 d after injection. These results will provide the data needed to construct a biokinetic model for the unperturbed biokinetics of 60Co in rats, which will subsequently be used to evaluate the impact of administered decorporating agents on organ radiation doses. The animal model described in this paper is representative of that used for other routes of radionuclide administration such as inhalation, ingestion and wound contamination that have been studied at LBERI in support of the MCART and NIAID programs.

    The detonation of a radiological dispersion device may result in a situation where individuals inhale radioactive materials and require rapid assessment of internal contamination. The feasibility of using a 2×2-inch sodium-iodide detector to determine the committed effective dose to an individual following acute inhalation of gamma-emitting radionuclides was investigated. Experimental configurations of point sources with a polymethyl methacrylate slab phantom were used to validate Monte Carlo simulations. The validated detector model was used to simulate the responses for four detector positions on six different anthropomorphic phantoms. The nuclides examined included (241)Am, (60)Co, (137)Cs, (131)I and (192)Ir. Biokinetic modelling was employed to determine the distributed activity in the body as a function of post-inhalation time. The simulation and biokinetic data were used to determine time-dependent count-rate values at optimal detector locations on the body for each radionuclide corresponding to a target committed effective dose (E50) value of 250 mSv.

    Soil and groundwater contaminated with jet fuel at Terminal One of the JFK International Airport in New York have been remediated using dual phase extraction (DPE) and bioventing. Two areas were remediated using 51 DPE wells and 20 air sparging/air injection wells. The total area remediated by the DPE wells is estimated to be 4.8 acres. Groundwater was extracted to recover nonaqueous phase and aqueous phase jet fuel from the shallow aquifer and treated above ground by the following processes; oil/water separation, iron-oxidation, flocculation, sedimentation, filtration, air stripping and liquid-phase granular activated carbon (LPGAC) adsorption. The extracted vapors were treated by vapor-phase granular activated carbon (VPGAC) adsorption in one area, and catalytic oxidation and VPGAC adsorption in another area. After 6 months of remediation, approximately 5,490 lbs. of volatile organic compounds (VOCs) were removed by soil vapor extraction (SVE), 109,650 lbs. of petroleum hydrocarbons were removed from the extracted groundwater, and 60,550 lbs. of petroleum hydrocarbons were biologically oxidized by subsurface microorganisms. Of these three mechanisms, the rate of petroleum hydrocarbon removal was the highest for biological oxidation in one area and by groundwater extraction in another area.

    A broad spectrum of organic chemicals is essential to modern society. Once discharged from industrial, domestic and urban sources into the urban wastewater collection system they may transfer to the residual solids during wastewater treatment and assessment of their significance and implications for beneficial recycling of the treated sewage sludge biosolids is required. Research on organic contaminants (OCs) in biosolids has been undertaken for over thirty years and the increasing body of evidence demonstrates that the majority of compounds studied do not place human health at risk when biosolids are recycled to farmland. However, there are 143,000 chemicals registered in the European Union for industrial use and all could be potentially found in biosolids. Therefore, a literature review of 'emerging' OCs in biosolids has been conducted for a selection of chemicals of potential concern for land application based upon human toxicity, evidence of adverse effects on the environment and endocrine disruption. To identify monitoring and research priorities the selected chemicals were ranked using an assessment matrix approach. Compounds were evaluated based upon environmental persistence, human toxicity, evidence of bioaccumulation in humans and the environment, evidence of ecotoxicity and the number and quality of studies focussed on the contaminant internationally. The identified chemicals of concern were ranked in decreasing order of priority: perfluorinated chemicals (PFOS, PFOA); polychlorinated alkanes (PCAs), polychlorinated naphthalenes (PCNs); organotins (OTs), polybrominated diphenyl ethers (PBDEs), triclosan (TCS), triclocarban (TCC); benzothiazoles; antibiotics and pharmaceuticals; synthetic musks; bisphenol A, quaternary ammonium compounds (QACs), steroids; phthalate acid esters (PAEs) and polydimethylsiloxanes (PDMSs). A number of issues were identified and recommendations for the prioritisation of further research and monitoring of 'emerging' OCs for the

    2016-09-01

    This review is a discussion of special issues associated with the medical and public health management of persons at risk of internal contamination from radionuclides, following various radiological mass-casualty scenarios, as well as definition, discussion and use of the Clinical Decision Guidance (CDG) in such scenarios. Specific medical countermeasures are available for reducing the internal radiation dose and the subsequent stochastic and deterministic risks to persons internally contaminated with radionuclides from nuclear power plant, fuel processing and nuclear weapon accidents/incidents. There is a public health need for rapidly identifying and quantifying the 'source term' of such radiation exposures and assessment of the associated committed doses, so that appropriate medical countermeasure(s) can be given as soon as possible. The CDG, which was initially defined in NCRP-161, was specifically developed to be a new public health tool for facilitating the integration of local community healthcare professionals into the general medical, mass casualty, triage and treatment response of internally contaminated populations.

    Purge-and-trap gas chromatography/mass spectrometry is evaluated for the quantitation of part-per-billion levels of volatile organic contaminants in bulk vegetable oils. Results using 2 purge techniques (direct purging of the heated oil and purging after dispersing the oil on an aluminum oxide powder) and 2 quantitative methods (standard curve and deuterium-labeled internal standard addition) are reported. Twenty volatile compounds and 8 vegetable oils were investigated. Recovery data and estimated detection limits for each compound are reported for each purge technique. Generally acceptable recoveries (70-130% for more than 90% of the analyte spikes) and acceptable detection levels (approximately 4-10 ppb) were obtained for all compounds using either the external standard curve of the deuterium-isotope-labeled internal standard. The use of a dispersant (such as alumina) for sample purging resulted in poor recoveries of the highly volatile contaminants. 16 refs., 3 figs., 4 tabs.

    This paper has briefly analyzed the publication status of Chinese stomatology papers in 2009 with statistics from Journal Citation Reports provided by Thomson Scientific. Only those papers with the first author coming from the mainland of China were included for calculations. We have found a significant increase in the number of SCIE-indexed papers, most of which were published by six dental institutions in China. Among all Chinese medical institutions, West China School of Stomatology Sichuan University is the first dental institution to enter the top-20 list with the most publications, and it also ranks the 9th in the number of outstanding articles. West China School of Stomatology Sichuan University and the Forth Military Medical University are the only two dental institutions in China which have published SCIE-indexed papers over a hundred. The former has published the most SCIE-indexed stomatology papers, while the latter has the highest average impact factor. As the laboratories and funds in China have close connections with various dental hospitals, the pratice of translational medicine in dentistry is fast and fluent.

  17. Two steps of insulin receptor internalization depend on different domains of the beta-subunit [published erratum appears in J Cell Biol 1993 Nov;123(4):1047

    PubMed Central

    1993-01-01

    The internalization of signaling receptors such as the insulin receptor is a complex, multi-step process. The aim of the present work was to determine the various steps in internalization of the insulin receptor and to establish which receptor domains are implicated in each of these by the use of receptors possessing in vitro mutations. We find that kinase activation and autophosphorylation of all three regulatory tyrosines 1146, 1150, and 1151, but not tyrosines 1316 and 1322 in the COOH-terminal domain, are required for the ligand-specific stage of the internalization process; i.e., the surface redistribution of the receptor from microvilli where initial binding occurs to the nonvillous domain of the cell. Early intracellular steps in insulin signal transduction involving the activation of phosphatidylinositol 3'-kinase are not required for this redistribution. The second step of internalization consists in the anchoring of the receptors in clathrin- coated pits. In contrast to the first ligand specific step, this step is common to many receptors including those for transport proteins and occurs in the absence of kinase activation and receptor autophosphorylation, but requires a juxta-membrane cytoplasmic segment of the beta-subunit of the receptor including a NPXY sequence. Thus, there are two independent mechanisms controlling insulin receptor internalization which depend on different domains of the beta-subunit. PMID:8376461

    Eggs are a major source of human infections with Salmonella. Therefore controlling egg contamination in laying hen flocks is one of the main targets for control programmes. A study was carried out to assess the effect of oral vaccination with TAD Salmonella vac E, TAD Salmonella vac T and with both vaccines TAD Salmonella vac E and TAD Salmonella vac T, on colonization of the reproductive tract and internal egg contamination of laying hens with Salmonella Enteritidis. Three groups of 30 laying hens were vaccinated at 1 day, 6 weeks and 16 weeks of age with either one of the vaccine strains, or a combination of both vaccine strains, while a fourth group was left unvaccinated. At 24 weeks of age, the birds were intravenously challenged with 0.5 ml containing 5 x 10(7)cfu Salmonella Enteritidis PT4 S1400/94. The number of oviducts from which Salmonella was isolated, was significantly lower in the vaccinated than in the non-vaccinated hens at 3 weeks post-challenge. Significantly less egg contents were Salmonella positive in the birds vaccinated with TAD Salmonella vac E or TAD Salmonella vac T (12/105 batches of eggs in both groups) than in the unvaccinated birds (28/105 batches of eggs). Internal egg contamination in the hens vaccinated with both TAD Salmonella vac E and TAD Salmonella vac T was even more reduced, as over the whole experiment, only one batch of eggs was positive. In conclusion, these data indicate that vaccination of laying hens with these live vaccines could be considered as a valuable tool in controlling internal egg contamination.

    On March 11, 2011, a magnitude 9.0 earthquake and subsequent tsunami damaged nuclear reactors at the Fukushima Daiichi complex in Japan, resulting in radionuclide release. In response, US officials augmented existing radiological screening at its ports of entry (POEs) to detect and decontaminate travelers contaminated with radioactive materials. During March 12 to 16, radiation screening protocols detected 3 travelers from Japan with external radioactive material contamination at 2 air POEs. Beginning March 23, federal officials collaborated with state and local public health and radiation control authorities to enhance screening and decontamination protocols at POEs. Approximately 543 000 (99%) travelers arriving directly from Japan at 25 US airports were screened for radiation contamination from March 17 to April 30, and no traveler was detected with contamination sufficient to require a large-scale public health response. The response highlighted synergistic collaboration across government levels and leveraged screening methods already in place at POEs, leading to rapid protocol implementation. Policy development, planning, training, and exercising response protocols and the establishment of federal authority to compel decontamination of travelers are needed for future radiological responses. Comparison of resource-intensive screening costs with the public health yield should guide policy decisions, given the historically low frequency of contaminated travelers arriving during radiological disasters.

    Histopathological findings are important to the understanding of toxicity profiles of pesticides. The liver is often a target organ of chemicals. In the present study, histopathological findings in the liver cited in the pesticides risk assessment reports published by the Food Safety Commission of Japan were classified. The histopathological findings were obtained in repeated-dose 90-day oral toxicity studies of mice, rats and dogs and carcinogenicity studies of rodents. After the classification, a thesaurus was constructed based on the International Harmonization of Nomenclature and Diagnostic (INHAND) Criteria. We recommend the use of INHAND criteria in risk assessment reports to improve mutual understanding between applicants and risk assessors.

    Background A proportion of people with mental health problems require longer term care in a psychiatric or social care institution. However, there are no internationally agreed quality standards for institutional care and no method to assess common care standards across countries. We aimed to identify the key components of institutional care for people with longer term mental health problems and the effectiveness of these components. Methods We undertook a systematic review of the literature using comprehensive search terms in 11 electronic databases and identified 12,182 titles. We viewed 550 abstracts, reviewed 223 papers and included 110 of these. A "critical interpretative synthesis" of the evidence was used to identify domains of institutional care that are key to service users' recovery. Results We identified eight domains of institutional care that were key to service users' recovery: living conditions; interventions for schizophrenia; physical health; restraint and seclusion; staff training and support; therapeutic relationship; autonomy and service user involvement; and clinical governance. Evidence was strongest for specific interventions for the treatment of schizophrenia (family psychoeducation, cognitive behavioural therapy (CBT) and vocational rehabilitation). Conclusion Institutions should, ideally, be community based, operate a flexible regime, maintain a low density of residents and maximise residents' privacy. For service users with a diagnosis of schizophrenia, specific interventions (CBT, family interventions involving psychoeducation, and supported employment) should be provided through integrated programmes. Restraint and seclusion should be avoided wherever possible and staff should have adequate training in de-escalation techniques. Regular staff supervision should be provided and this should support service user involvement in decision making and positive therapeutic relationships between staff and service users. There should be clear lines

    During a maintenance period at a Korean nuclear power plant, internal exposure of radiation workers occurred by the inhalation of (131)I that was released into the reactor building from a primary system opening due to defective fuels. The internal activity in radiation workers contaminated by (131)I was immediately measured using a whole body counter (WBC). A whole body counting was performed again a few days later, considering the factors of equilibrium in the body. The intake and the committed effective dose were estimated based on the WBC results. The intake was also calculated by hand, based on both the entrance records to the reactor building, and the counted results of the air concentration for (131)I were compared with the whole body counting results.

    The trace contaminant control system (TCCS) located in the International Space Station s (ISS) U.S. laboratory module employs physical adsorption, thermal catalytic oxidation, and chemical adsorption to remove trace chemical contamination produced by equipment offgassing and anthropogenic sources from the cabin atmosphere. The chemical adsorption stage, consisting of a packed bed of granular lithium hydroxide (LiOH), is located after the thermal catalytic oxidation stage and is designed to remove acid gas byproducts that may be formed in the upstream oxidation stage. While in service on board the ISS, the LiOH bed exhibited a change in flow resistance that leading to flow control difficulties in the TCCS. Post flight evaluation revealed LiOH granule size attrition among other changes. An experimental program was employed to investigate mechanisms hypothesized to contribute to the change in the packed bed s flow resistance. Background on the problem is summarized, including a discussion of likely mechanisms. The experimental program is described, results are presented, and implications for the future are discussed.

    A thermodynamic model is developed to predict adsorption equilibrium in the International Space Station water processor's multifiltration beds. The model predicts multicomponent adsorption equilibrium behavior using single-component isotherm parameters and fictitious components representing the background matrix. The fictitious components are determined by fitting total organic carbon and tracer isotherms with the ideal adsorbed solution theory. Multicomponent isotherms using a wastewater with high surfactant and organic compound concentrations are used to validate the equilibrium description on a coconut-shell-based granular activated carbon (GAC), coal-based GAC, and a polymeric adsorbent.

    Through a detailed analysis of the FAO database, we have constructed a generalized representation of the nitrogen transfers characterizing the current agro-food system (GRAFS) of 12 macro-regions of the world in terms of functional relationships between crop farming, livestock breeding and human nutrition. Based on this model, and maintaining the current cropland areas and the performance of cropping and livestock systems in each region, we have assessed the possibilities of meeting the protein requirements of the estimated world population in 2050, according to various combinations of three critical drivers namely human diet (total amount of protein consumed and share of animal protein in this total), regional livestock production and crop fertilization intensity, in each region. The results show that feeding the projected 2050 world population would generally imply higher levels of inter-regional trade and of environmental nitrogen contamination than the current levels, but that the scenarios with less recourse to inter-regional trade generally produce less N losses to the environment. If an equitable human diet (in terms of protein consumption) is to be established globally (the same in all regions of the world), the fraction of animal protein should not exceed 40% of a total ingestion of 4 kgN capita-1 yr-1, or 25% of a total consumption of 5 kgN capita-1 yr-1. Our results show that slightly improving the agronomical performance in the most deficient regions (namely Maghreb, the Middle East, sub-Saharan Africa, and India) would make it possible not only to meet the global protein requirements with much less international trade (hence more food sovereignty), but also to reduce N environmental contamination the most efficiently.

    2012-02-01

    Medical journals are published by scientific societies, universities, publishing agencies and other for-profit or non-profit organizations. The traditional way to cover the expenses in printed journals has been a "subscribers pay" model. The rise of electronic versions in the internet, either together with the printed version or replacing it entirely, plus a progressive adherence to an "open access" for electronic versions, has created financial difficulties. Therefore, the "authors pay" model has been added. Both models can be subsidized by commercial or institutional advertising, but still a main source for financing relies either in subscriptions or in authors' payments. A small source of income that helps to cover publishing costs is a "charge for manuscript reception", currently applied by several journals. Those authors whose work has institutional or external support can use their grants to cover any charges, but the situation is more difficult for those who do not have such support. Since 1872, Sociedad Médica de Santiago-Chilean Society of Internal Medicine, owner and publisher of Revista Médica de Chile, has employed the "subscribers pay" model, subsidized by commercial advertising and temporary sponsors (Chilean government and others). The printed journal is reproduced in an open access electronic version, in www.scielo.cl. The increasing cost of both publications systems demands a time for reflection.

As a result of this interest, international contracts funded by DOE (USA), NRRA, EC and DGXL were instituted to study the experience of radioactive waste management accumulated at the PA "Mayak" territory, including proposed rehabilitation of the contaminated territories. However, at the initial stage of international research, the works were not coordinated and often duplicated each other, which was taken by the public and mass media as a serious divergence of opinion between the scientists on the risk assessment for the population. Many years of research resulted in elaboration of a common scientific approach to the solution of the problems of water resources contamination at the PA "Mayak" territory. A successful experience of coordinating the international projects to study radionuclide migration with surface and ground waters at the PA "Mayak" territory is demonstrated, as well as the risk assessment for the population. Substantiation for rehabilitation measures can be based on long-term predictions and modeling research that are continuing under these international projects.

  4. Data Sharing & Publishing at Nature Publishing Group

    2015-12-01

    In recent years, the research community has come to recognize that upon-request data sharing has important limitations1,2. The Nature-titled journals feel that researchers have a duty to share data without undue qualifications, in a manner that allows others to replicate and build upon their published findings. Historically, the Nature journals have been strong supporters of data deposition in communities with existing data mandates, and have required data sharing upon request in all other cases. To help address some of the limitations of upon-request data sharing, the Nature titles have strengthened their existing data policies and forged a new partnership with Scientific Data, to promote wider data sharing in discoverable, citeable and reusable forms, and to ensure that scientists get appropriate credit for sharing3. Scientific Data is a new peer-reviewed journal for descriptions of research datasets, which works with a wide of range of public data repositories4. Articles at Scientific Data may either expand on research publications at other journals or may be used to publish new datasets. The Nature Publishing Group has also signed the Joint Declaration of Data Citation Principles5, and Scientific Data is our first journal to include formal data citations. We are currently in the process of adding data citation support to our various journals. 1 Wicherts, J. M., Borsboom, D., Kats, J. & Molenaar, D.

    Purpose: I-131 is one of the most frequent radionuclides used in nuclear medicine departments. The radiation workers, who manipulate the unsealed radio-toxic iodine, should be monitored for internal contamination. In this study a protocol was established for estimating I-131 activity absorbed in the thyroid glands of the nuclear medicine staff in normal working condition and also in accidents. Methods: I-131 with the activity of 10 μCi was injected inside the thyroid gland of a home-made anthropomorphic neck phantom. The phantom is made up of PMMA as soft tissue, and Aluminium as bone. The dose rate at different distances from the surface of the neck phantom was measured using a scintillator detector for duration of two months. Then, calibration factors were obtained, for converting the dose rate at each distance to the iodine activity inside the thyroid. Results: According to the results of this study, the calibration factors for converting the dose rates (nSv/h) at distances of 0cm, 1cm, 6cm, 11cm, and 16cm to the activity (kBq) inside the thyroid were found to be 0.03, 0.04, 0.14, 0.29, and 0.49 . Conclusion: This method can be effectively used for quick estimation of the I-131 concentration inside the thyroid of the staff for daily checks in normal working conditions and also in accidents.

  6. Academic nightmares: Predatory publishing.

    2016-12-02

    Academic researchers who seek to publish their work are confronted daily with a barrage of e-mails from aggressive marketing campaigns that solicit them to publish their research with a specialized, often newly launched, journal. Known as predatory journals, they often promise high editorial and publishing standards, yet their exploitive business models, poor quality control, and minimal overall transparency victimize those researchers with limited academic experience and pave the way for low-quality articles that threaten the foundation of evidence-based research. Understanding how to identify these predatory journals requires thorough due diligence on the part of the submitting authors, and a commitment by reputable publishers, institutions, and researchers to publicly identify these predators and eliminate them as a threat to the careers of young scientists seeking to disseminate their work in scholarly journals.

  7. Fairness in scientific publishing

    Major changes are afoot in the world of academic publishing, exemplified by innovations in publishing platforms, new approaches to metrics, improvements in our approach to peer review, and a focus on developing and encouraging open access to scientific literature and data. The FAIR acronym recommends that authors and publishers should aim to make their output Findable, Accessible, Interoperable and Reusable. In this opinion article, I explore the parallel view that we should take a collective stance on making the dissemination of scientific data fair in the conventional sense, by being mindful of equity and justice for patients, clinicians, academics, publishers, funders and academic institutions. The views I represent are founded on oral and written dialogue with clinicians, academics and the publishing industry. Further progress is needed to improve collaboration and dialogue between these groups, to reduce misinterpretation of metrics, to minimise inequity that arises as a consequence of geographic setting, to improve economic sustainability, and to broaden the spectrum, scope, and diversity of scientific publication.

  8. Standards for contamination control

    Standards are an important component of national and international trade. We depend upon standards to assure that manufactured parts will work together, wherever they are made, and that we speak the same technical language, no matter what language we speak. Understanding is important in order to know when to take exceptions to or tailor the standard to fit the job. Standards that are used in contamination control have increased in numbers over the years as more industries have had to improve their manufacturing processes to enhance reliability or yields of products. Some older standards have been revised to include new technologies, and many new standards have been developed. Some of the new standards were written for specific industries while others apply to many industries. Many government standards have been replaced with standards from nongovernmental standards organizations. This trend has been encouraged by U.S. law that requires the government to use commercial standards where possible. This paper reviews some of the more important standards for the aerospace industry, such as IEST-STD-CC1246 and ISO 14644-1, that have been published in recent years. Benefits, usage, and problems with some standards will be discussed. Some standards are referenced, and websites of some standards organizations are listed.

    “If you want to make an impact among your colleagues, look especially at the journals that they’re reading and publishing in” Dr H Goldman, Chief Editor of Polar Research Writing medical articles is highly competitive. Many hours are expended conducting research, and even more hours writing and rewriting the manuscript. Furthermore, countless hours are spent chasing references and performing complex statistics. However, when it comes to understanding the target audience, are authors guilty of not investing as much effort to get maximum impact from the fruits of their labour? The issue of where to send your manuscript has never been more critical. Most clinicians receive daily invitations via email to submit work to journals that sound legitimate and valid. But are they? Although many journals are reputable, many others are not. This stems partly from the sharp decline in paper journals and the parallel exponential rise in digital journals. With intense pressure to publish, it is hard not to be seduced by online journal marketing ploys. For instance, one researcher used www.randomtextgenerator.com to make up an article and submitted it to 37 open access journals over a period of 2 weeks.1 At least 17 accepted his work and agreed to publish his article once a $500 ‘processing fee’ had been paid. Investing time and effort in ‘where to publish’ is time well spent. It is an exercise in understanding the target audience that will benefit most from the publication. Doing this at an early stage in the publishing process saves valuable time and resources. More importantly, this increases the chances of acceptance. So what are the tips for checking journal legitimacy and avoiding the trap of predatory journals? >Check the journal website and look through a recent issue.>Is the journal indexed?

    2012-08-01

    We all learn in elementary school not turn in other people's writing as if it were our own (plagiarism), and in high school science labs not to fake our data. But there are many other practices in scientific publishing that are depressingly common and almost as unethical. At about the 20 percent level authors are deliberately hiding recent work -- by themselves as well as by others -- so as to enhance the apparent novelty of their most recent paper. Some people lie about the dates the data were obtained, to cover up conflicts of interest, or inappropriate use of privileged information. Others will publish the same conference proceeding in multiple volumes, or publish the same result in multiple journals with only trivial additions of data or analysis (self-plagiarism). These shady practices should be roundly condemned and stopped. I will discuss these and other unethical actions I have seen over the years, and steps editors are taking to stop them.

  16. Some Case Studies on Metal-Microbe Interactions to Remediate Heavy Metals- Contaminated Soils in Korea

    NASA Astrophysics Data System (ADS)

    Chon, Hyo-Taek

    2015-04-01

    Conventional physicochemical technologies to remediate heavy metals-contaminated soil have many problems such as low efficiency, high cost and occurrence of byproducts. Recently bioremediation technology is getting more and more attention. Bioremediation is defined as the use of biological methods to remediate and/or restore the contaminated land. The objectives of bioremediation are to degrade hazardous organic contaminants and to convert hazardous inorganic contaminants to less toxic compounds of safe levels. The use of bioremediation in the treatment of heavy metals in soils is a relatively new concept. Bioremediation using microbes has been developed to remove toxic heavy metals from contaminated soils in laboratory scale to the contaminated field sites. Recently the application of cost-effective and environment-friendly bioremediation technology to the heavy metals-contaminated sites has been gradually realized in Korea. The merits of bioremediation include low cost, natural process, minimal exposure to the contaminants, and minimum amount of equipment. The limitations of bioremediation are length of remediation, long monitoring time, and, sometimes, toxicity of byproducts for especially organic contaminants. From now on, it is necessary to prove applicability of the technologies to contaminated sites and to establish highly effective, low-cost and easy bioremediation technology. Four categories of metal-microbe interactions are generally biosorption, bioreduction, biomineralization and bioleaching. In this paper, some case studies of the above metal-microbe interactions in author's lab which were published recently in domestic and international journals will be introduced and summarized.

    On 1 January 2004 I will be assuming the position of Editor-in-Chief of Journal of Physics A: Mathematical and General (J. Phys. A). I am flattered at the confidence expressed in my ability to carry out this challenging job and I will try hard to justify this confidence. The previous Editor-in-Chief, Ed Corrigan, has worked tirelessly for the last five years and has done an excellent job for the journal. Everyone at the journal is profoundly grateful for his leadership and for his achievements. Before accepting the position of Editor-in-Chief, I visited the office of J. Phys. A to examine the organization and to assess its strengths and weaknesses. This office is located at the Institute of Physics Publishing (IOPP) headquarters in Bristol. J. Phys. A has been expanding rapidly and now publishes at the rate of nearly 1000 articles (or about 14,000 pages) per year. The entire operation of the journal is conducted in a very small space---about 15 square metres! Working in this space are six highly intelligent, talented, hard working, and dedicated people: Neil Scriven, Publisher; Mike Williams, Publishing Editor; Rose Gray and Sarah Nadin, Publishing Administrators; Laura Smith and Steve Richards, Production Editors. In this small space every day about eight submitted manuscripts are downloaded from the computer or received in the post. These papers are then processed and catalogued, referees are selected, and the papers are sent out for evaluation. In this small space the referees' reports are received, publication decisions are made, and accepted articles are then published quickly by IOPP. The whole operation is amazingly efficient. Indeed, one of the great strengths of J. Phys. A is the speed at which papers are processed. The average time between the receipt of a manuscript and an editorial decision is under sixty days. (Many distinguished journals take three to five times this amount of time.) This speed of publication is an extremely strong enticement for

    Scientific journals ask authors to put their manuscripts, at the submission stage, sometimes in a complex style and a specific pagination format that are time consuming while it is unclear yet that the submitted manuscripts will be accepted. In the case of rejections, authors need to submit to another journal most likely with a different style and formatting that require additional work and time. To save authors' time, publishers should allow authors to submit their manuscripts in any format and to comply with the style required by the targeted journal only in revised versions, but not at the submission step when the manuscripts are not yet approved for publication.

    The most visible activity of the American Geophysical Union is its publication of scientific journals. There are eight of these: Journal of Geophysical Research—Space Physics (JGR I), Journal of Geophysical Research—Solid Earth (JGR II), Journal of Geophysical Research—Oceans and Atmospheres (JGR III), Radio Science (RS), Water Resources Research (WRR), Geophysical Research Letters (GRL), Reviews of Geophysics and Space Physics (RGSP), and the newest, Tectonics.AGU's journals have established solid reputations for scientific excellence over the years. Reputation is not sufficient to sustain a high quality journal, however, since other factors enter into an author's decision on where to publish his or her work. In this article the characteristics of AGU's journals are compared with those of its competitors, with the aim of furnishing guidance to prospective authors and a better understanding of the value of the products to purchasers.

  13. Stability of reference masses: VI. Mercury and carbonaceous contamination on platinum weights manufactured at a similar time as the international and national prototype kilograms

    NASA Astrophysics Data System (ADS)

    2013-10-01

    The stability of prototype kilogram reference masses has been a long-standing question within the SI, with mass loss or gain at the surface being the principal concern. In papers I, III and IV of this series we showed mercury and organic carbonaceous contamination to be significant in sample surfaces exposed to typical prototype kilogram storage environments. In this work, we have examined the surfaces of six platinum mass standards manufactured in the mid-19th century. We used x-ray photoelectron spectroscopy in order to identify mercury and carbonaceous contamination, and assess the validity of our previous models for the rate of increase. We use white-light interferometry to study surface roughness and polishing damage. We see mercury on all six of the 19th century polished prototypes we analysed. For one weight, manufactured around 1830, we see a quantity of mercury roughly equivalent to 250 µg if present on the surface of a prototype kilogram at the same mass per unit area. The quantities of these contaminations calculated from our XPS spectra are in good agreement with the theoretical models developed in papers III and IV for the growth of mercury and carbonaceous contamination, respectively, and increase our confidence that these processes are indeed happening at the surface of polished kilogram prototypes in most (if not all) cases. We discuss some potential sources of mercury contamination, though the most likely source remains the accidental breakage of thermometers and barometers containing mercury in the past. Mercury in laboratory air can adsorb and diffuse into defects and grain boundaries, especially at polished surfaces. We consider some possible ways to improve the situation, for example by placing a gold foil in the proximity of a prototype to act as a ‘getter’ that will preferentially adsorb mercury.

    Blom, Harry J. J.

    Over the past 15 years, internet technology changed the ways of publishing tremendously. It is truly revolutionary that both fresh and historic science publications are so much easier to search and find. This revolution has not been completed and all parties involved in science publishing are continuously adjusting their activities to the new rules and opportunities. From a commercial publisher's perspective, I will extrapolate what happens today to predict what happens in the next few years with journal subscriptions, book publishing, marketing, production and other steps in the publishing process.

  17. EPIC: Electronic Publishing is Cheaper.

    Collection and analysis of spacecraft cabin air samples are necessary to assess the cabin air quality with respect to crew health. Both toxicology and engineering disciplines work together to achieve an acceptably clean cabin atmosphere. Toxicology is concerned with limiting the risk to crew health from chemical sources, setting exposure limits, and analyzing air samples to determine how well these limits are met. Engineering provides the means for minimizing the contribution of the various contaminant generating sources by providing active contamination control equipment on board spacecraft and adhering to a rigorous material selection and control program during the design and construction of the spacecraft. A review of the rationale and objectives for sampling spacecraft cabin atmospheres is provided. The presently-available sampling equipment and methods are reviewed along with the analytical chemistry methods employed to determine trace contaminant concentrations. These methods are compared and assessed with respect to actual cabin air quality monitoring needs. Recommendations are presented with respect to the basic sampling program necessary to ensure an acceptably clean spacecraft cabin atmosphere. Also, rationale and recommendations for expanding the scope of the basic monitoring program are discussed.

    Throughout the world, individuals and populations of herons are affected by environmental contaminants, leading to direct mortality, decreased reproductive success, or degradation of feeding habitat. Contaminants suspected or known to affect herons include organochlorine compounds, organophosphorus insecticides, trace elements, and petroleum (Parnell et al. 1988).General reviews on the effects of pesticides on birds (Risebrough 1986, 1991) and colonial water birds (Nisbet 1980) are presented elsewhere. The objective of this chapter is to review toxic effects of contaminants on herons. Unless otherwise noted, contaminant concentrations are presented as parts per million (ppm) on a wet weight (ww) basis.

  20. [Medical publishing in Norway 1905-2005].

    The nation-building process in Norway took mainly place before the Norwegian-Swedish union came to a close in 1905. This was not a dramatic change, though the end of the union did bring a lift to Norwegian national consciousness. In 1905 there were three general medical journals in Norway and approximately 1200 doctors. German was the most important language of international science, but most scientific publishing was done in Norwegian. After the Second World War, English became the dominating language of scientific communication. Twentieth-century medicine and medical publishing was an era of specialisation and internationalisation. Norwegian medicine has to a large extent been internationalised through Nordic cooperation, with the Nordic specialist journals being of particular importance. With increasing professionalism in research, international English-language journals have become the major channels of communication, though several Norwegian-language journals (on paper or on the internet) have been established and are of crucial importance to a national identity within medical specialties. In 2005 there is only one general medical journal in Norwegian, in a country with approximately 20,000 doctors. A national identity related to medical publishing is not given much attention, though national medicine is still closely tied in with national culture. Good clinical practice should be based on a firm knowledge of local society and local tradition. This is a challenge in contemporary medical publishing.

    This study compared a new live attenuated Salmonella Enteritidis vaccine candidate secreting Escherichia coli heat-labile enterotoxin B subunit (SE-LTB) with a commercial Salmonella Enteritidis (SE) vaccine for efficacy of protection against SE infection in laying hens. Chickens were divided into 3 groups of 20 each. Group A chickens were inoculated orally with phosphate-buffered saline and served as controls, group B chickens were inoculated orally with the vaccine candidate, and group C chickens were inoculated intramuscularly with a commercial vaccine, the primary inoculation in groups B and C being at 10 wk of age and the booster at 16 wk. Groups B and C showed significantly higher titers of plasma immunoglobulin G, intestinal secretory immunoglobulin A, and egg yolk immunoglobulin Y antibodies compared with the control group, and both vaccinated groups showed a significantly elevated cellular immune response. After virulent challenge, group B had significantly lower production of thin-shelled and/or malformed eggs and a significantly lower rate of SE contamination of eggs compared with the control group. Furthermore, the challenge strain was detected significantly less in all of the examined organs of group B compared with the control group. Group C had lower gross lesion scores only in the spleen and had lower bacterial counts only in the spleen, ceca, and ovary. These findings indicate that vaccination with the SE-LTB vaccine candidate can efficiently reduce internal egg and internal organ contamination by Salmonella and has advantages over the commercial vaccine.

    The journal publishing landscape is changing rapidly. With the massive move from print to online taking place at the end of the last century, we are now seeing a shift from traditional subscription based publishing model to ‘hybrid’ models and full Open Access publishing. Other major changes are taking place at the article interface level (from a static PDF to the “Article of the Future”), in data and code repository linking, in publishing data and code and hence make it citable and discoverable, and in many other subject area specific online innovations that are being introduced.Elsevier is actively involved - both in Open Access publishing, and in content innovation - in discussing, and taking the lead through many big and smaller scale initiatives. This presentation will outline Elsevier’s perspective on the future of scientific publishing with regards to these developments.

    Salmonella Senftenberg is uncommon in the United Kingdom. In January-June 2007, the Health Protection Agency reported on 55 primary human cases of Salmonella Senftenberg in England and Wales. In May 2007, fresh basil sold in the United Kingdom was found to be contaminated with Salmonella Senftenberg. We launched an investigation to elucidate the cause of this outbreak. Isolates were examined using plasmid profiling and pulsed-field gel electrophoresis, and the outbreak strain (SSFTXB.0014) was identified. We enquired via Enter-net whether other countries had isolated the outbreak strain, analyzed samples of fresh herbs from U.K. retailers, and interviewed patients on food history. Thirty-two patient-cases were referred to this outbreak in England and Wales. Onsets of illness occurred between 5 March and 6 June 2007. Fifty-six percent of patient-cases were females and 90% adults (>20 years old); three were admitted to hospital as a result of Salmonella infection. Scotland, Denmark, the Netherlands, and the United States reported on 19 cases of Salmonella Senftenberg infection presenting with the outbreak strain since January 2007. Eight samples of prepacked fresh basil imported from Israel tested positive with the same strain. A minority of patients could recall the consumption of basil before illness, and some reported consumption of products where basil was a likely ingredient. Environmental investigations in Israel did not identify the contamination source. Microbiological evidence suggested an association between contamination of fresh basil and the cases of Salmonella Senftenberg infection, leading to withdrawal of basil from all potentially affected batches from the U.K. market.

    The world wide web has brought about a paradigm shift in the way medical research is published and accessed. The ease with which a new journal can be started/hosted by publishing start-ups is unprecedented. The tremendous capabilities of the world wide web and the open access revolution when combined with a highly profitable business have attracted unscrupulous fraudulent operators to the publishing industry. The intent of these fraudulent publishers is solely driven by profit with utter disregard to scientific content, peer reviews and ethics. This phenomenon has been referred to as "predatory publishing". The "international" tag of such journals often betrays their true origins. The gold open access model of publishing, where the author pays the publisher, when coupled with a non-existent peer review threatens to blur the distinction between science and pseudoscience. The average researcher needs to be made more aware of this clear and present danger to the scientific community. Prevention is better than cure.

    Physica Scripta is an international physics journal published for the Royal Swedish Academy of Sciences on behalf of the Nordic Science Academies and Physical Societies. This issue marks the beginning of the partnership between the Royal Swedish Academy of Sciences and Institute of Physics Publishing (IOP). We look forward to a fruitful relationship in which Physica Scripta can profit from the international reach of IOP. Authors and readers will benefit from advance publication of articles on the web prior to receiving each month's journal issue. The peer-review system will continue to be managed by Professor Roger Wäppling who will assess each paper before assigning it to an external editor or sending it for refereeing. IOP will receive new article submissions and generate electronic documents suitable for use in the refereeing process. The editorial office in Sweden will then be responsible for these manuscripts up to the final publication decision. Accepted articles will be sent to IOP for copy-editing, typesetting, production and distribution. We aim to provide our authors, referees and readers with an enhanced service for this well-established journal. IOP will maintain and augment Physica Scripta's record in publishing a broad range of high-quality research papers and we will continue to publish Topical Issues as supplements to the regular 12 issues. The popular Comments articles will continue to be published in conjunction with regular papers under this new partnership. We hope that our subscribers will continue to enjoy reading Physica Scripta as a valuable resource for general physics research.

    Enteroviruses (EV) and human parechoviruses (HPeV) are endemic worldwide. These infections are a constant cause of hospitalisation and severe disease, predominantly in young children and infants. Coordinated monitoring and surveillance are crucial to control these infections. We have monitored EV and HPeV epidemiology in Amsterdam from 2007 to 2011 with real-time RT-PCR and direct genotyping, facilitating highly sensitive surveillance. Moreover, we conducted a literature survey of existing surveillance data for comparison. Only 14 studies were identified. While HPeV1 was most frequently detected in Amsterdam, EV-B viruses dominated nationally and internationally. Furthermore, the top 10 strains detected differed yearly and per study. However, detection and typing methods were too varied to allow direct comparison and comprehension of the worldwide distribution and circulation patterns of the different genotypes. This limited a direct response to anticipate peaks. Uniform European monitoring programmes are essential to aid prediction of outbreaks and disease management.

    Background Dissemination bias in clinical research severely impedes informed decision-making not only for healthcare professionals and patients, but also for funders, research ethics committees, regulatory bodies and other stakeholder groups that make health-related decisions. Decisions based on incomplete and biased evidence cannot only harm people, but may also have huge financial implications by wasting resources on ineffective or harmful diagnostic and therapeutic measures, and unnecessary research. Owing to involvement of multiple stakeholders, it remains easy for any single group to assign responsibility for resolving the problem to others. Objective To develop evidence-informed general and targeted recommendations addressing the various stakeholders involved in knowledge generation and dissemination to help overcome the problem of dissemination bias on the basis of previously collated evidence. Methods Based on findings from systematic reviews, document analyses and surveys, we developed general and targeted draft recommendations. During a 2-day workshop in summer 2013, these draft recommendations were discussed with external experts and key stakeholders, and refined following a rigorous and transparent methodological approach. Results Four general, overarching recommendations applicable to all or most stakeholder groups were formulated, addressing (1) awareness raising, (2) implementation of targeted recommendations, (3) trial registration and results posting, and (4) systematic approaches to evidence synthesis. These general recommendations are complemented and specified by 47 targeted recommendations tailored towards funding agencies, pharmaceutical and device companies, research institutions, researchers (systematic reviewers and trialists), research ethics committees, trial registries, journal editors and publishers, regulatory agencies, benefit (health technology) assessment institutions and legislators.

  13. Proteome changes in rat serum after a chronic ingestion of enriched uranium: Toward a biological signature of internal contamination and radiological effect.

    The civilian and military use of uranium results in an increased risk of human exposure. The toxicity of uranium results from both its chemical and radiological properties that vary with isotopic composition. Validated biomarkers of health effects associated with exposure to uranium are neither sensitive nor specific to uranium radiotoxicity and/or radiological effect. This study aimed at investigating if serum proteins could be useful as biomarkers of both uranium exposure and radiological effect. Male Sprague-Dawley rats were chronically exposed through drinking water to low levels (40mg/L, corresponding to 1mg of uranium per animal per day) of either 4% (235)U-enriched uranium (EU) or 12% EU during 6 weeks. A proteomics approach based on two-dimensional electrophoresis (2D-DIGE) and mass spectrometry (MS) was used to establish protein expression profiles that could be relevant for discriminating between groups, and to identify some differentially expressed proteins following uranium ingestion. It demonstrated that the expressions of 174 protein spots over 1045 quantified spots were altered after uranium exposure (p<0.05). Using both inferential and non-supervised multivariate statistics, we show sets of spots features that lead to a clear discrimination between controls and EU exposed groups on the one hand (21 spots), and between 4% EU and 12% EU on the other hand (7 spots), showing that investigation of the serum proteome may possibly be of relevance to address both uranium contamination and radiological effect. Finally, using bioinformatics tools, pathway analyses of differentially expressed MS-identified proteins find that acute phase, inflammatory and immune responses as well as oxidative stress are likely involved in the response to contamination, suggesting a physiological perturbation, but that does not necessarily lead to a toxic effect.

    Following Japan's 2011 Fukushima nuclear incident, we assessed voluntary-based monitoring behavior in Minamisoma City-located 10-40 km from the Fukushima nuclear plant-to inform future monitoring strategies. The monitoring in Minamisoma included occasional free of charge internal-radiation-exposure measurements. Out of around 70,000 individuals residing in the city before the incident, a total of 45,788 residents (female: 52.1%) aged ≥21 were evaluated. The monitoring prevalence in 2011-2012 was only 30.2%, and this decreased to 17.9% in 2013-2014. Regression analyses were performed to estimate factors associated with the monitoring prevalence and participation behavior. The results show that, in comparison with the age cohort of 21-30 years, the cohort of 71-80 and ≥81 years demonstrated significantly lower monitoring prevalence; female residents had higher monitoring prevalence than male residents; those who were living in evacuation zones at the time of the incident had higher monitoring prevalence than those who lived outside any of the evacuation zones; for those living outside Fukushima and neighboring Prefectures post-incident monitoring prevalence decreased significantly in 2013-2014. Our findings inform the discussion on the concepts of radiation risk perception and accessibility to monitoring and societal decision-making regarding the maintenance of the monitoring program with low monitoring prevalence. We also stress the possibility that the monitoring can work both to check that internal contamination levels are within acceptable limits, and as a risk communication tool, alleviating individuals' concern and anxiety over radiation contamination.

    The purpose of this chapter is to provide an overview of the ecotoxicology of major classes of environmental contaminants, with respect to sources, environmental chemistry, most likely routes of exposure, potential bioaccumulation and biomagification, mechanisms of toxicity, and effects on potentially vulnerable species of mammalian wildlife. Major contaminants reviewed were selected on the basis of their use patterns, availability and potential toxicity to wild mammals. These included pesticides used in agroecosystems (organochlorines, organophosphorus and carbamate compounds, anticoagulants, herbicides and fungicides), various organic pollutants (chlorobenzenes, chlorophenols, polychlorinated biphenyls, dibenzodioxins and dibenzofurans, and polycyclic aromatic hydrocarbons), heavy metals (lead, mercury, and cadmium), agricultural drainwater mixtures, leachates and radionuclides. Many of the above aspects of ecotoxicology and contaminants will be expanded upon in subsequent chapters of this book as they relate to distinct mammalian species and potential risk.

    Department of Public Health Engineering (DPHE), Bangladesh first identified their groundwater arsenic contamination in 1993. But before the international arsenic conference in Dhaka in February 1998, the problem was not widely accepted. Even in the international arsenic conference in West-Bengal, India in February, 1995, representatives of international agencies in Bangladesh and Bangladesh government attended the conference but they denied the groundwater arsenic contamination in Bangladesh. School of Environmental Studies (SOES), Jadavpur University, Kolkata, India first identified arsenic patient in Bangladesh in 1992 and informed WHO, UNICEF of Bangladesh and Govt. of Bangladesh from April 1994 to August 1995. British Geological Survey (BGS) dug hand tube-wells in Bangladesh in 1980s and early 1990s but they did not test the water for arsenic. Again BGS came back to Bangladesh in 1992 to assess the quality of the water of the tube-wells they installed but they still did not test for arsenic when groundwater arsenic contamination and its health effects in West Bengal in Bengal delta was already published in WHO Bulletin in 1988. From December 1996, SOES in collaboration with Dhaka Community Hospital (DCH), Bangladesh started analyzing hand tube-wells for arsenic from all 64 districts in four geomorphologic regions of Bangladesh. So far over 54,000 tube-well water samples had been analyzed by flow injection hydride generation atomic absorption spectrometry (FI-HG-AAS). From SOES water analysis data at present we could assess status of arsenic groundwater contamination in four geo-morphological regions of Bangladesh and location of possible arsenic safe groundwater. SOES and DCH also made some preliminary work with their medical team to identify patients suffering from arsenic related diseases. SOES further analyzed few thousands biological samples (hair, nail, urine and skin scales) and foodstuffs for arsenic to know arsenic body burden and people sub

    The time dependence of the angular reflectance from molecularly contaminated optical surfaces in the Vacuum Ultraviolet (VUV) is measured. The light scattering measurements are accomplished in situ on optical surfaces in real time during deposition of molecular contaminants. The measurements are taken using non-coherent VUV sources with the predominant wavelengths being the Krypton resonance lines at 1236 and 1600 A. Detection of the scattered light is accomplished using a set of three solar blind VUV photomultipliers. An in-plane VUV BRDF (Bidirectional Reflectance Distribution Functions) experiment is described and details of the ongoing program to characterize optical materials exposed to the space environment is reported.

    The subject of these conference proceedings is the groundwater contamination. It is by nature multifarious - dealing with detection and monitoring, prevention, abatement and containment, and correction and restoration of contaminated groundwater - it intrinsically encompasses myriad disciplines, and it involves all levels of government. Also, the subject of groundwater contamination is complex because decisions concerning groundwater pollution control that are scientifically sound, technologically within the state of the art, economically feasible, politically tractable, legally sustainable, socially acceptable, morally accountable, and organizationally implementable must be grounded on appropriate information and intelligence bases in their respective areas - science, technology, economics, politics, the law, society, ethics, and management. Indeed, the human health effects (e.g., cancer, damage to the central nervous system, liver and kidney damage) and non-health effects (economic hardship to industry, agriculture, households, and municipalities; environmental impacts; social impacts) necessitate that we, as a society, address in a somber way the following variations of the same question: How safe is safe enough How clean is safe enough The enormous cost - in billions of dollars over the next decade - that various studies project for the prevention, detection and monitoring, abatement and containment, and correction and restoration of groundwater contamination make an answer to these questions even more urgent. There are sixteen papers in these proceedings.

    Authors of clinical articles have similar motivations and rules than authors in other scientific fields. In addition, medical research must obey specific ethical rules that apply to studies involving human subjects, including biological samples, tissues, cellular or sub cellular samples obtained from them. When submitting their reports for publication, authors must declare that they have followed such ethical rules and also should declare any possible conflict of interest that may have arisen. External peer reviewers and the editors should also conform to limitations by eventual conflicts of interest. Authors should respect specific ethical norms that apply to the process of submitting, publishing and reproducing their manuscripts. In recent years, the editors of Revista Médica de Chile have become aware of five instances of misconduct committed by authors of articles submitted or already published. Four correspond to redundant publications and one exhibits overt plagiarism in the text and syntax. Appropriate actions have been taken following recommendations published by the International Committee of Medical Journal Editors, the World Association of Medical Editors and other groups.

    Direct internal reforming (DIR) operation of a solid oxide fuel cell (SOFC) is a very attractive concept for downsizing and cost reduction of SOFC systems. This study aimed to develop stable operation of a DIR-SOFC fuelled by biogas. The current-voltage (I-V) curves of 2 × 2 cm2 planar SOFCs (anode- and electrolyte-supported cells, ASC and ESC, respectively.) were measured at 800 °C in the direct feed of a simulated biogas mixture (CH4/CO2 = 1), and the flexible structured catalyst material (paper-structured catalyst (PSC)) was applied on the anode material for performance enhancement. By applying a hydrotalcite (HT)-dispersed PSC (HT-PSC), the sulfur tolerance of the SOFC in the DIR operation was remarkably improved. By the effect of the HT-PSC, for both ASC and ESC, a stable cell voltage higher than 800 mV was obtained over 200 h at 0.2 A cm-2 in the direct feed of simulated biogas under 5 ppm H2S poisoning.

    This compact disc (CD) contains the 35 reports in the Contaminant Hazard Reviews (CHR) that were published originally between 1985 and 1999 in the U.S. Department of the Interior Biological Report series. The CD was produced because printed supplies of these reviews--a total of 105,000--became exhausted and demand remained high. Each review was prepared at the request of environmental specialists of the U.S. Fish and Wildlife Service and each contained specific information on the following: mirex, cadmium, carbofuran, toxaphene, selenium, chromium, polychlorinated biphenyls, dioxins, diazinon, mercury, polycyclic aromatic hydrocarbons, arsenic, chlorpyrifos, lead, tin, index issue, pentachlorophenol, atrazine, molybdenum, boron, chlordane, paraquat, cyanide, fenvalerate, diflubenzuron, zinc, famphur, acrolein, radiation, sodium monofluoroacetate, planar PCBs, silver, copper, nickel, and a cumulative index to chemicals and species. Each report reviewed and synthesized the technical literature on a single contaminant and its effects on terrestrial plants and invertebrates, aquatic plants and animals, avian and mammalian wildlife, and other natural resources. The subtopics include contaminant sources and uses; physical, chemical, and metabolic properties; concentrations in field collections of abiotic materials and living organisms; deficiency effects, where appropriate; lethal and sublethal effects, including effects on survival, growth, reproduction, metabolism, mutagenicity, teratogenicity, and carcinogenicity; proposed criteria for the protection of human health and sensitive natural resources; and recommendations for additional research.

    Recently, a major new area of application has emerged for personal computers. This application area isdesktop publishing or DTP. This market is expected to be one of the most rapidlygrowing and lucratrative of all personal computerapplications. It is possiblethataf all personal computer applicationstodate, DTP requiresthe mostsophisticated interconnection of hardware and software. Top rated sofware for DTP like Pagemaker by Aldus and Ventura Publisher by Xerox import files and images that can be created on other machines by software beyond the control of the DTP package. Xerox Ventura Publisher Version 1.1,forexample, can importfromten(10)differenttextformats, nine (9)different line-art formats and three (3) image formats. Users who are willing to conform to one of these acceptable formats can have their software output integrated intothe printed page. Additionally, many DTP systems employ an input scanner for scanning pictures or diagrams etc. Whatwe will examine are some of the systems issues relating to the whole DTP system.

    Survival of Salmonella enterica subsp. enterica serovar Poona on surface and stem scar portions of inoculated cantaloupe following sanitizer application, transfer of pathogen from the rind to the flesh during cutting, and growth of Salmonella Poona on cantaloupe cubes over 15 days of refrigerated storage were investigated. Cantaloupes inoculated with a rifampin-resistant strain of Salmonella Poona (10(7) CFU/ml) for 3 min and dried for 12 h were washed with chlorine (200 mg free chlorine per liter, 3 min), lactic acid (2%, 2 min), or ozone (30 mg/liter, 5 min). Fresh-cut cantaloupe cubes were prepared by (i) cutting the cantaloupe and then removing the rind or by (ii) peeling the rind and then cutting the flesh into pieces. The numbers of Salmonella bacteria recovered were higher in the stem scar portion (6.3 ± 0.3 log CFU/cm(2)) than the surface (4.8 ± 0.2 log CFU/cm(2)). Surface treatment with tap water or chlorine did not reduce Salmonella numbers, while treatment with lactic acid or ozone reduced Salmonella by 2.5 or 2.3 log CFU/cm(2), respectively. The use of lactic acid to sanitize the cantaloupes resulted in less Salmonella transfer to flesh during cutting; Salmonella numbers decreased to below detectable levels over 9 days of refrigerated (4°C) storage. Cutting cantaloupes after peeling the rind was more effective at reducing transfer of Salmonella to the internal tissue than cutting of cantaloupes prior to rind removal. These data suggest that treatment of cantaloupe rinds with lactic acid or ozone may be effective at reducing Salmonella numbers, while lactic acid application resulted in reduction of Salmonella transfer to cantaloupe flesh.

    The detonation of a radiological dispersion device or other radiological incidents could result in widespread releases of radioactive materials and intakes of radionuclides by affected individuals. Transportable radiation monitoring instruments could be used to measure radiation from gamma-emitting radionuclides in the body for triaging individuals and assigning priorities to their bioassay samples for in vitro assessments. The present study derived sets of calibration factors for four instruments: the Ludlum Model 44-2 gamma scintillator, a survey meter containing a 2.54 × 2.54-cm NaI(Tl) crystal; the Captus 3000 thyroid uptake probe, which contains a 5.08 × 5.08-cm NaI(Tl) crystal; the Transportable Portal Monitor Model TPM-903B, which contains two 3.81 × 7.62 × 182.9-cm polyvinyltoluene plastic scintillators; and a generic instrument, such as an ionization chamber, that measures exposure rates. The calibration factors enable these instruments to be used for assessing inhaled or ingested intakes of any of four radionuclides: Co, I, Cs, and Ir. The derivations used biokinetic models embodied in the DCAL computer software system developed by the Oak Ridge National Laboratory and Monte Carlo simulations using the MCNPX radiation transport code. The three physical instruments were represented by MCNP models that were developed previously. The affected individuals comprised children of five ages who were represented by the revised Oak Ridge National Laboratory pediatric phantoms, and adult men and adult women represented by the Adult Reference Computational Phantoms described in Publication 110 of the International Commission on Radiological Protection. These calibration factors can be used to calculate intakes; the intakes can be converted to committed doses by the use of tabulated dose coefficients. These calibration factors also constitute input data to the ICAT computer program, an interactive Microsoft Windows-based software package that estimates intakes of

    In this study, the effect of Indian reference BOttle MAnnikin aBsorber (BOMAB) neck with axial cavity and American National Standards Institute (ANSI)/International Atomic Energy Agency (IAEA) thyroid phantom using pencil sources of (133)Ba ((131)I simulant) on counting efficiency (CE) is seen experimentally in static geometry for whole-body monitoring system comprising 10.16-cm diameter and 7.62-cm-thick NaI(Tl) detector. The CE estimated using the neck part of BOMAB phantom is 50.2% lower in comparison with ANSI phantom. In rest of the studies FLUKA code is used for Monte Carlo simulations using ANSI/IAEA thyroid phantom. The simulation results are validated in static geometries with experimental CE and the differences are within 1.3%. It is observed that CE for pencil source distribution is 3.97% higher for (133)Ba in comparison with CE of (131)I source. Simulated CE for pencil source distribution is 4.7% lower in comparison with uniform source distribution in the volume of thyroid for (131)I. Since the radiation workers are of different physique; overlying tissue thickness (OTT) and neck-to-detector distance play an important role in the calculation of activity in thyroid. The CE decreases with increase in OTT and is found to be 5.5% lower if OTT is changed from 1.1 to 2 cm. Finally, the simulations are carried out to estimate the variation in CE due to variation in the neck-to-detector distance. The CE is 6.2% higher if the neck surface-to-detector distance is decreased from 21.4 to 20.4 cm and it goes on increasing up to 61.9% if the distance is decreased to 15.4 cm. In conclusion, the calibration of whole-body monitoring system for (131)I should be carried out with ANSI/IAEA thyroid phantom, the neck-to-detector distance controlled or the CE corrected for this, and the CE should be corrected for OTT.

  2. Two recently sequenced vertebrate genomes are contaminated with apicomplexan species of the Sarcocystidae family.

    PubMed

    Orosz, Ferenc

    2015-11-01

    This paper highlights a general problem, namely that host genome sequences can easily be contaminated with parasite sequences, thus careful isolation of genetic material and careful bioinformatics analysis are needed in all cases. Two recently published genomes are shown here to be contaminated with sequences of apicomplexan parasites which belong to the Sarcocystidae family. Sequences of the characteristic apicomplexan organelle, the apicoplast, were used as queries in BLASTN searches against nucleotide sequences of various animal groups looking for possible contamination. Draft genomes of a bird, Colinus virginianus (Halley et al., 2014), and a bat, Myotis davidii (Zhang et al., 2013) were found to contain at least six and 17 contigs, respectively, originating from the apicoplast of an apicomplexan species, and other genes specific to this phylum can also be found in the published genomes. Obviously, the sources of the genetic material, the muscle and the kidney of the animals, respectively, contained the parasitic cysts. Phylogenetic analyses using 18S rRNA and internal transcribed spacer 1 genes show that the parasite contaminating C. virginianus is a species of Sarcocystis related to ones known to cycle between avian and mammalian hosts. In the case of M. davidii it belongs to the Nephroisospora genus, the only member of which, Nephroisospora eptesici, has been recently identified from the kidney of big brown bats (Eptesicus fuscus).

    This paper will summarize studies of carbon impurity sources, contamination, and migration developed through JET methane gas injection experiments. These studies were analyzed using the 2D SOL code EDGE2D/NIMBUS. The code is capable of repeating the JET analysis using the ITER geometry and SOL plasma. This allows assessment of whether the physical processes occurring in JET might also occur in ITER, and thus whether the JET results transfer, in any sense, to the ITER plasmas. Certainly, the ITER choice of wall materials (W and Be) is different than for the present JET C studies. So the present status of these studies is to relate JET carbon behavior to carbon in ITER.JET carbon sources were studied spectroscopically and analyzed with atomic physics models in EDGE2D. The carbon sources are dominated by chemical sputtering at rates which are within a factor-of-two of the published literature. The JET carbon contamination is dominated by main chamber sources which are ionized in the main chamber SOL about 1-2 cm from the separatrix. Contamination occurs from carbon ions which diffuse across the field lines and reach the separatrix before they can parallel transport to the divertor. JET carbon migration was studied by injecting methane composed of {sup 13}C on the last run day before an opening and then analyzing removed tiles to identify migration to those locations. Modeling was accomplished by the same EDGE2D models that were used to describe the carbon sources and contamination. The entire migration process is complicated.

  7. Contaminant hydrogeology

    SciTech Connect

    Fetter, C.W.

    1993-01-01

    Hydrogeology is a rapidly evolving field in which new approaches and tools are being applied to solve problems. This new book fills an important niche. Fetter focuses primarily on chemical processes in the subsurface, avoiding duplication of materials that are covered in other, more classical texts. This book is an excellent follow-up to his earlier text, Applied Hydrogeology, and reviews only briefly the foundational concepts covered in the earlier textbook. Contaminant Hydrogeology is written at the graduate student level and assumes prerequisite courses in physics, chemistry, and hydrogeology. For the most part, each of the nine chapters covers a major area of concern common to applied contaminant studies. A thorough, theoretical treatment of solute transport through the vadose zone is presented, and a sample problem and a case study add unusually high value to this discussion of a topic that generally is not well understood in the practice. Topics covered include the Buckingham Flux Law, the Richards Equation, vapor-phase transport, equilibrium and nonequilibrium models of mass transport, and preferential flow paths. Nonaqueous-phase liquid migrations under both saturated and unsaturated conditions is covered for horizontal as well as vertical migration. Both light and dense nonaqueous phase liquids are presented, and Darcy's Law for two-phase flow is introduced. The strength of Contaminant Hydrogeology lies in the author's ability to translate concepts through practical experience. This book links the theoretical to the practical through example problems and case histories. It should be considered for use in graduate classes and would be a valuable reference in the library of any practicing hydrogeologist.

    Biomedical publishing stands at a crossroads. The traditional print, peer-reviewed, subscription journal has served science well but is now being called into question. Because of spiraling print journal costs and the worldwide acceptance of the Internet as a valid publication medium, there is a compelling opportunity to re-examine our current paradigm and future options. This report illustrates the conflicts and restrictions inherent in the current publishing model and examines how the single act of permitting authors to retain copyright of their scholarly manuscripts may preserve the quality-control function of the current journal system while allowing PubMed Central, the Internet archiving system recently proposed by the director of the National Institutes of Health, to simplify and liberate access to the world's biomedical literature.

    Measurement of the total organic carbon content in water is important in assessing contamination levels in high purity water for power generation, pharmaceutical production and electronics manufacture. Even trace levels of organic compounds can cause defects in manufactured products. The Sievers Model 800 Total Organic Carbon (TOC) Analyzer, based on technology developed for the Space Station, uses a strong chemical oxidizing agent and ultraviolet light to convert organic compounds in water to carbon dioxide. After ionizing the carbon dioxide, the amount of ions is determined by measuring the conductivity of the deionized water. The new technique is highly sensitive, does not require compressed gas, and maintenance is minimal.

    This paper presents a metadata model for physical samples, developed by CSIRO for its role as an allocating agent. The model is essential for connecting various samples to the Web in a systematic manner. It serves as a basis for registering and publishing samples from researchers and laboratories in CSIRO with the International Geo Sample Number (IGSN). The model is simple, extensible and publicly available. We specify how existing controlled vocabularies are incorporated into the model development, and discuss their relevance and limitations. We also describe the mappings between the developed model and existing standards. This is necessary to extend the model's adoption across various science domains. The model has been implemented and tested in the context of two large sample repositories in CSIRO. The results demonstrate the effectiveness of the metadata model while maintaining its flexibility to adapt to various sample types.

    The focus of the Fourth International Radiopharmaceutical Dosimetry Symposium was to explore the impact of current developments in nuclear medicine on absorbed dose calculations. This book contains the proceedings of the meeting including the edited discussion that followed the presentations. Topics that were addressed included the dosimetry associated with radiolabeled monoclonal antibodies and blood elements, ultrashort-lived radionuclides, and positron emitters. Some specific areas of discussion were variations in absorbed dose as a result of alterations in the kinetics, the influence of radioactive contaminants on dose, dose in children and in the fetus, available instrumentation and techniques for collecting the kinetic data needed for dose calculation, dosimetry requirements for the review and approval of new radiopharmaceuticals, and a comparison of the effect on the thyroid of internal versus external irradiation. New models for the urinary blader, skeleton including the active marrow, and the blood were presented. Several papers dealt with the validity of traditional ''average-organ'' dose estimates to express the dose from particulate radiation that has a short range in tissue. These problems are particularly important in the use of monoclonal antibodies and agents used to measure intracellular functions. These proceedings have been published to provide a resource volume for anyone interested in the calculation of absorbed radiation dose.

    2016-10-01

    Scientific journals that are owned by a learned society, like the Journal of Neurochemistry (JNC), which is owned by the International Society for Neurochemistry (ISN), benefit the scientific community in that a large proportion of the income is returned to support the scientific mission of the Society. The income generated by the JNC enables the ISN to organize conferences as a platform for members and non-members alike to share their research, supporting researchers particularly in developing countries by travel grants and other funds, and promoting education in student schools. These direct benefits and initiatives for ISN members and non-members distinguish a society journal from pure commerce. However, the world of scholarly publishing is changing rapidly. Open access models have challenged the business model of traditional journal subscription and hence provided free access to publicly funded scientific research. In these models, the manuscript authors pay a publication cost after peer review and acceptance of the manuscript. Over the last decade, numerous new open access journals have been launched and traditional subscription journals have started to offer open access (hybrid journals). However, open access journals follow the general scheme that, of all participating parties, the publisher receives the highest financial benefit. The income is generated by researchers whose positions and research are mostly financed by taxpayers' or funders' money, and by reviewers and editors, who frequently are not reimbursed. Last but not least, the authors pay for the publication of their work after a rigorous and sometimes painful review process. JNC itself has an open access option, at a significantly reduced cost for Society members as an additional benefit. This article provides first-hand insights from two former Editors-in-Chief, Kunihiko Suzuki and Leslie Iversen, about the history of JNC's ownership and about the difficulties and battles fought along the way to

  3. Contaminant resorption during soil washing

    SciTech Connect

    Gombert, D.

    1993-10-01

    To evaluate the applicability of soil washing to a specific site requires some basic research in how contaminants are bound. Much can be learned from sequential extraction methodology based on micronutrient bioavailability studies wherein the soil matrix is chemically dissected to selectively remove particular fixation mechanisms independently. This procedure uses a series of progressively more aggressive solvents to dissolve the principle phases that make up a soil, however, the published studies do not appear to consider the potential for a contaminant released from one type of site to resorb on another site during an extraction. This physical model assumes no ion exchange or adsorption at sites either previously occupied by other ions, or exposed by the dissolution. Therefore, to make engineering use of the sequential extraction data, the release of contamination must be evaluated relative to the effects of resorption. Time release studies were conducted to determine the optimum duration for extraction to maximize complete destruction of the target matrix fraction while minimizing contaminant resorption. Tests with and without a potassium brine present to inhibit cesium resorption indicated extraction efficiency could be enhanced by as much as a factor of ten using the brine.

    Hu, Min; Liu, Jian-Ping; Wu, Xiao-Ke

    2014-12-01

    Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.

    Effective contamination control must encompass all aspects of ground and flight from design of the system through the end of mission life. Design systems are needed to minimize sensitivity to contamination, ease of cleaning, and contaminant production. Facilities and procedures are critical to maintaining cleanliness during ground operations. Flight operations should be planned so as to minimize contamination. More data from flights are required to assess the adequacy of designs and operations. Standards and specifications should include contamination control requirements.

    Disclosed are examples of apparatuses for evaporative purification of a contaminated liquid. In each example, there is a vessel for storing the contaminated fluid. The vessel includes a surface coated with a layer of superhydrophobic material and the surface is at least partially in contact with the contaminated liquid. The contaminants do not adhere to the surface as the purified liquid evaporates, thus allowing the contaminants to be harvested.

    2015-03-01

    Online publishing is challenging, and potentially changing, the role of publishers in both managing the peer-review process and disseminating the work that they publish in meeting contrasting needs from diverse groups of research communities. Recognizing the value of peer-review as a fundamental service to authors and the research community, the underlying principles of managing the process for journals published by IOP Publishing remain unchanged and yet the potential and demand for alternative models exists. This talk will discuss the traditional approach to peer-review placed in the context of this changing demand.

    This article introduces predatory publishers in the context of biomedical sciences research. It describes the characteristics of predatory publishers, including spamming and using fake metrics, and it describes the problems they cause for science and universities. Predatory journals often fail to properly manage peer review, allowing pseudo-science to be published dressed up as authentic science. Academic evaluation is also affected, as some researchers take advantage of the quick, easy, and cheap publishing predatory journals provide. By understanding how predatory publishers operate, researchers can avoid becoming victimized by them.

    1977-01-01

    The environmental contaminants (isolated as off-gases in Skylab and Apollo missions) were evaluated. Specifically, six contaminants were evaluated for their effects on the behavior of juvenile baboons. The concentrations of contaminants were determined through preliminary range-finding studies with laboratory rats. The contaminants evaluated were acetone, methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK), trichloroethylene (TCE), heptane and Freon 21. When the studies of the individual gases were completed, the baboons were also exposed to a mixture of MEK and TCE. The data obtained revealed alterations in the behavior of baboons exposed to relatively low levels of the contaminants. These findings were presented at the First International Symposium on Voluntary Inhalation of Industrial Solvents in Mexico City, June 21-24, 1976. A preprint of the proceedings is included.

  20. Publishing South African scholarship in the global academic community

    PubMed Central

    2015-01-01

    South Africa's academic publishing history has been profoundly influenced by its colonial heritage. This is reflected in the publication of Transactions of the South African Philosophical Society (later, the Royal Society of South Africa) from 1878. Although the Society and journal sought to promote original research about South Africa, it was modelled after the Royal Society in London and formed part of an imperial scientific community. As the local higher education institutions grew more independent and research-focused, local scholarly publishing developed as well, with university presses playing an increasingly important role. The University of South Africa (Unisa) Press started publishing departmental journals in the 1950s, with a focus on journals that ‘speak to the student’, and it is today the only South African university press with an active journals publishing programme. As external funding declined and the country became intellectually isolated in the high apartheid period, the Press managed to attract journals that could no longer be subsidized by learned societies and other universities. More recently, new co-publishing arrangements have brought South African journals back into an international intellectual community. Although some argue that this constitutes a re-colonization of South African knowledge production, it is also an innovative strategy for positioning local research in a global context. PMID:26495579

  1. Electronic publishing in radiology: beginnings, current status, and expanding horizons.

    PubMed

    Chew, Felix S; Llewellyn, Kevin; Olsen, Kathryn M

    2004-10-01

    Electronic publishing in radiology began in the 1980s and gathered momentum as use of the personal computer and subsequently the World Wide Web became commonplace. The ease of access and wide distribution that the Internet affords have presented both experts and lay users with the challenge of distinguishing reliable from unreliable material. In the field of radiology, peer-reviewed journals, the sine qua non of reliability in the scientific realm, began to appear in online versions in 1988, and now, nearly all such journals currently have online versions. Electronic versions of textbooks and textbook-like material have become more common, although the vast majority of publishers' catalogs are traditional print books. Electronic material is more common in the fields of internal, emergency, and family medicine than in the field of diagnostic radiology. The latest publishing medium is the personal digital assistant. Challenges that face electronic publishing include the issues of permanent archiving, citation, and indexing. Peer review seems to be the best method for distinguishing reliable from unreliable information. The use of Web technology has improved the logistics of peer review, and some journals have begun posting peer reviews themselves on the Web alongside peer-reviewed articles. Electronic publishing has changed the manner in which radiologists obtain information, providing wider, more immediate access.

  5. How to write an article: Preparing a publishable manuscript!

    PubMed

    Shidham, Vinod B; Pitman, Martha B; Demay, Richard M

    2012-01-01

    Most of the scientific work presented as abstracts (platforms and posters) at various conferences have the potential to be published as articles in peer-reviewed journals. This DIY (Do It Yourself) article on how to achieve that goal is an extension of the symposium presented at the 36(th) European Congress of Cytology, Istanbul, Turkey (presentation available on net at http://alturl.com/q6bfp). The criteria for manuscript authorship should be based on the ICMJE (International Committee of Medical Journal Editors) Uniform Requirements for Manuscripts. The next step is to choose the appropriate journal to submit the manuscript and review the 'Instructions to the authors' for that journal. Although initially it may appear to be an insurmountable task, diligent organizational discipline with a little patience and perseverance with input from mentors should lead to the preparation of a nearly perfect publishable manuscript even by a novice. Ultimately, the published article is an excellent track record of academic productivity with contribution to the general public good by encouraging the exchange of experience and innovation. It is a highly rewarding conduit to the personal success and growth leading to the collective achievement of continued scientific progress. Recent emergences of journals and publishers offering the platform and opportunity to publish under an open access charter provides the opportunity for authors to protect their copyright from being lost to conventional publishers. Publishing your work on this open platform is the most rewarding mission and is the recommended option in the current modern era.[This open access article can be linked (copy-paste link from HTML version of this article) or reproduced FREELY if original reference details are prominently identifiable].

  6. Chemical contamination of ground water in India

    1996-10-01

    Ground water is the main source of drinking water in rural areas and many urban areas in India. In addition, it has been increasingly used for irrigation in farmland. Contamination of ground water by persistent inorganic and organic chemicals has emerged as a major environmental concern in recent years. Nitrate, fluoride, heavy metals and organochlorine compounds are found to be major contaminants of ground water in different parts of the country. At many places the concentrations of these chemicals exceed national and international guideline values for drinking water. While large concentrations of heavy metals come from industrial sources, agricultural activities are responsible for ground water contamination by nitrate and organochlorine insecticides.

  7. A survey of authors publishing in four megajournals.

    PubMed

    Solomon, David J

    2014-01-01

    Aim. To determine the characteristics of megajournal authors, the nature of the manuscripts they are submitting to these journals, factors influencing their decision to publish in a megajournal, sources of funding for article processing charges (APCs) or other fees and their likelihood of submitting to a megajournal in the future. Methods. Web-based survey of 2,128 authors who recently published in BMJ Open, PeerJ, PLOS ONE or SAGE Open. Results. The response rate ranged from 26% for BMJ Open to 47% for SAGE Open. The authors were international, largely academics who had recently published in both subscription and Open Access (OA) journals. Across journals about 25% of the articles were preliminary findings and just under half were resubmissions of manuscripts rejected by other journals. Editors from other BMJ journals and perhaps to a lesser extent SAGE and PLOS journals appear to be encouraging authors to submit manuscripts that were rejected by the editor's journals to a megajournal published by the same publisher. Quality of the journal and speed of the review process were important factors across all four journals. Impact factor was important for PLOS ONE authors but less so for BMJ Open authors, which also has an impact factor. The review criteria and the fact the journal was OA were other significant factors particularly important for PeerJ authors. The reputation of the publisher was an important factor for SAGE Open and BMJ Open. About half of PLOS ONE and around a third of BMJ Open and PeerJ authors used grant funding for publishing charges while only about 10% of SAGE Open used grant funding for publication charges. Around 60% of SAGE Open and 32% of PeerJ authors self-funded their publication fees however the fees are modest for these journals. The majority of authors from all 4 journals were pleased with their experience and indicated they were likely to submit to the same or similar journal in the future. Conclusions. Megajournals are drawing an

  11. ContaMiner and ContaBase: a webserver and database for early identification of unwantedly crystallized protein contaminants

    PubMed Central

    Hungler, Arnaud; Momin, Afaque; Diederichs, Kay; Arold, Stefan, T.

    2016-01-01

    Solving the phase problem in protein X-ray crystallography relies heavily on the identity of the crystallized protein, especially when molecular replacement (MR) methods are used. Yet, it is not uncommon that a contaminant crystallizes instead of the protein of interest. Such contaminants may be proteins from the expression host organism, protein fusion tags or proteins added during the purification steps. Many contaminants co-purify easily, crystallize and give good diffraction data. Identification of contaminant crystals may take time, since the presence of the contaminant is unexpected and its identity unknown. A webserver (ContaMiner) and a contaminant database (ContaBase) have been established, to allow fast MR-based screening of crystallographic data against currently 62 known contaminants. The web-based ContaMiner (available at http://strube.cbrc.kaust.edu.sa/contaminer/) currently produces results in 5 min to 4 h. The program is also available in a github repository and can be installed locally. ContaMiner enables screening of novel crystals at synchrotron beamlines, and it would be valuable as a routine safety check for ‘crystallization and preliminary X-ray analysis’ publications. Thus, in addition to potentially saving X-ray crystallographers much time and effort, ContaMiner might considerably lower the risk of publishing erroneous data. PMID:27980519

    1990-12-20

    The internal dosimetry program at the Savannah River Site (SRS) consists of radiation protection programs and activities used to detect and evaluate intakes of radioactive material by radiation workers. Examples of such programs are: air monitoring; surface contamination monitoring; personal contamination surveys; radiobioassay; and dose assessment. The objectives of the internal dosimetry program are to demonstrate that the workplace is under control and that workers are not being exposed to radioactive material, and to detect and assess inadvertent intakes in the workplace. The Savannah River Site Internal Dosimetry Technical Basis Manual (TBM) is intended to provide a technical and philosophical discussion of the radiobioassay and dose assessment aspects of the internal dosimetry program. Detailed information on air, surface, and personal contamination surveillance programs is not given in this manual except for how these programs interface with routine and special bioassay programs.

  14. Multi-Canister overpack internal HEPA filters

    SciTech Connect

    SMITH, K.E.

    1998-11-03

    The rationale for locating a filter assembly inside each Multi-Canister Overpack (MCO) rather than include the filter in the Cold Vacuum Drying (CVD) process piping system was to eliminate the potential for contamination to the operators, processing equipment, and the MCO. The internal HEPA filters provide essential protection to facility workers from alpha contamination, both external skin contamination and potential internal depositions. Filters installed in the CVD process piping cannot mitigate potential contamination when breaking the process piping connections. Experience with K-Basin material has shown that even an extremely small release can result in personnel contamination and costly schedule disruptions to perform equipment and facility decontamination. Incorporating the filter function internal to the MCO rather than external is consistent with ALARA requirements of 10 CFR 835. Based on the above, the SNF Project position is to retain the internal HEPA filters in the MCO design.

  10. New journals for publishing medical case reports.

    Akers, Katherine G

    2016-04-01

    Because they do not rank highly in the hierarchy of evidence and are not frequently cited, case reports describing the clinical circumstances of single patients are seldom published by medical journals. However, many clinicians argue that case reports have significant educational value, advance medical knowledge, and complement evidence-based medicine. Over the last several years, a vast number (∼160) of new peer-reviewed journals have emerged that focus on publishing case reports. These journals are typically open access and have relatively high acceptance rates. However, approximately half of the publishers of case reports journals engage in questionable or "predatory" publishing practices. Authors of case reports may benefit from greater awareness of these new publication venues as well as an ability to discriminate between reputable and non-reputable journal publishers.

    In the 350th year of the academic journal, it is perhaps surprising that Publishers have done such a poor job of explaining exactly what it is we do, how we add value to scientific discourse, and how we justify our charges.IOP Publishing occupies a somewhat unique position as publishing house wholly owned by a major society, and with approximately half of its portfolio managed on behalf of other societies and institutions, including several significant examples in the fields of Astronomy and Astrophysics.Studies of the costs of publishing, several different business models, and some major investment initiatives aimed at improving the author and reader experience, will be drawn upon as context to consider the true costs of publishing.

  13. Implementation of a geodatabase of published and non-published data on the catastrophic Vaiont landslide

    On the 9th October 1963 a catastrophic landslide suddenly occurred on the southern slope of the Vaiont dam reservoir. A mass of approximately 270 million m3 collapsed into the reservoir generating a wave which overtopped the dam and hit the town of Longarone and other villages: almost 2000 people lost their lives. Numerous questions, legal, economic, societal, and scientific have accompanied its history, before and after October 9th 1963. Several investigations and attempted interpretations of the slope collapse have been carried out during the last 45 years, however a comprehensive explanation of both the triggering and the dynamics of the phenomenon has yet to be provided. Research on the Vaiont landslide, published in the international literature after 1963, can conveniently subdivided into the following: 1) papers based on geological and geomorphological data collected at the Vaiont site; 2) papers focussing on specific aspects including the geotechnical properties of the materials involved, the physical and rheological behavior of the failure mass and the varied methods of stability analysis applied in order to understand the factors involved in landslide initiation and development; 3) papers dealing with the Vaiont landslide in a more comprehensive way. The Vaiont landslide has significantly increased our understanding of the kinematics and dynamics of such catastrophic phenomena. However, much of the data on the Vaiont slide exists in a non-electronic hard copy format. A geodatabase on the Vaiont Slide has been developed, utilising and updating the information collected by Genevois & Ghirotti (2005). An electronic bibliography of all published papers, theses and non-published technical reports, and all available site data forms the core of a newly developed geodatabase on the Vaiont landslide. In addition, data on engineering geological mapping, topography, rock mechanics, groundwater and monitoring have been centralized in a GIS system to allow a re

    The compilation was designed to help U.S. Fish and Wildlife Service contaminant specialists evaluate the degree of contamination of a soil, based on chemical analyses. Included are regulatory criteria, opinions, brief descriptions of scientific articles, and miscellaneous information that might be useful in making risk assessments. The intent was to make hard-to-obtain material readily available to contaminant specialists, but not to critique the material or develop new criteria. The compilation is to be used with its index, which includes about 200 contaminants. Entries include soil contaminant criteria from other countries, contaminant guidelines for applying sewage sludge to soil, guidelines for evaluating sediments, background soil concentrations for various elements, citations to scientific articles that may help estimate the potential movement of soil contaminants into wildlife food chains, and a few odds and ends. Articles on earthworms were emphasized because they are a natural bridge between soil and many species of wildlife.

  15. Catalyst Substrates Remove Contaminants, Produce Fuel

    NASA Technical Reports Server (NTRS)

    2012-01-01

    A spacecraft is the ultimate tight building. We don t want any leaks, and there is very little fresh air coming in, says Jay Perry, an aerospace engineer at Marshall Space Flight Center. As a result, there is a huge potential for a buildup of contaminants from a host of sources. Inside a spacecraft, contaminants can be introduced from the materials that make spacecraft components, electronics boxes, or activities by the crew such as food preparation or cleaning. Humans also generate contaminants by breathing and through the body s natural metabolic processes. As part of the sophisticated Environmental Control and Life Support System on the International Space Station (ISS), a trace contaminant control system removes carbon dioxide and other impurities from the cabin atmosphere. To maintain healthy levels, the system uses adsorbent media to filter chemical contaminant molecules and a high-temperature catalytic oxidizer to change the chemical structure of the contaminants to something more benign, usually carbon dioxide and water. In the 1990s, while researching air quality control technology for extended spaceflight travel, Perry and others at Marshall were looking for a regenerable process for the continuous removal of carbon dioxide and trace chemical contaminants on long-duration manned space flights. At the time, the existing technology used on U.S. spacecraft could only be used once, which meant that a spacecraft had to carry additional spare parts for use in case the first one was depleted, or the spacecraft would have to return to Earth to exchange the components.

  18. Truth in Science Publishing: A Personal Perspective

    PubMed Central

    Südhof, Thomas C.

    2016-01-01

    Scientists, public servants, and patient advocates alike increasingly question the validity of published scientific results, endangering the public’s acceptance of science. Here, I argue that emerging flaws in the integrity of the peer review system are largely responsible. Distortions in peer review are driven by economic forces and enabled by a lack of accountability of journals, editors, and authors. One approach to restoring trust in the validity of published results may be to establish basic rules that render peer review more transparent, such as publishing the reviews (a practice already embraced by some journals) and monitoring not only the track records of authors but also of editors and journals.

    Science cannot progress without scientists reporting their findings. And yet researchers have given control of this central pillar of the scientific process to science publishers, who are in the business of serving the interests of their journals; these are not always the same as the interests of science. This editorial describes the problems with the process of preparing and publishing research findings, and with judging their veracity and significance, and then explains how we at Faculty of 1000 are starting to tackle the ‘deadly sins’ of science publishing.

    2014-01-01

    The principle of open-access (OA) publishing is more and more prevalent also on the field of laboratory medicine. Open-access journals (OAJs) are available online to the reader usually without financial, legal, or technical barriers. Some are subsidized, and some require payment on behalf of the author. OAJs are one of the two general methods for providing OA. The other one is self-archiving in a repository. The electronic journal of the IFCC (eJIFCC) is a platinum OAJ— i.e. there is no charge to read, or to submit to this journal. Traditionally, the author was required to transfer the copyright to the journal publisher. Publishers claimed this was necessary in order to protect author’s rights. However, many authors found this unsatisfactory, and have used their influence to affect a gradual move towards a license to publish instead. Under such a system, the publisher has permission to edit, print, and distribute the article commercially, but the author(s) retain the other rights themselves. An OA mandate is a policy adopted by a research institution, research funder, or government which requires researchers to make their published, peer-reviewed journal articles and conference papers OA by self-archiving their peer-reviewed drafts in a repository (“green OA”) or by publishing them in an OAJ (“gold OA”). Creative Commons (CC) is a nonprofit organization that enables the sharing and use of creativity and knowledge through free legal tools. The free, easy-to-use copyright licenses provide a simple, standardized way to give the public permission to share and use creative work. CC licenses let you easily change your copyright terms from the default of “all rights reserved” to “some rights reserved.” OA publishing also raises a number of new ethical problems (e.g. predatory publishers, fake papers).

    2016-01-01

    Objective: The aim of this study is to characterize the patterns and trends in the editorial process and features of the first decade of Pharmacy Practice, with the final goal of initiating a benchmarking process to enhance the quality of the journal. Methods: Metadata of all of the articles published from 2006 issue #3 to 2016 issue #2 were extracted from PubMed and complemented by a manual data extraction process on the full-text articles. Citations of these articles were retrieved from Web of Science (WOS), Scopus, and Google Scholar on August 15, 2016. The references from all of the articles published by Pharmacy Practice in 2015 were also extracted. International collaboration was explored with a network analysis. Results: A total of 40 issues were published in this timespan, including 349 articles, 91.1% of which were original research articles. The number of citations received by these articles varies from 809, as reported by the WOS, to the 1162 reported by Scopus and the 2610 reported by Google Scholar. The journals cited by Pharmacy Practice are mainly pharmacy journals, including Pharm Pract (Granada), Int J Clin Pharm, Am J Health-Syst Pharm, Am J Pharm Educ, and Ann Pharmacother. Only 17.3% of the articles involved international collaboration. Delays in the editorial process increased in 2013, mainly due to an increase in acceptance delay (mean=138 days). Conclusion: Pharmacy Practice has improved its visibility and impact over the past decade, especially after 2014, when the journal became indexed in PubMed Central. The editorial process duration is one of the weaknesses that should be tackled. Further studies should investigate if the low international collaboration rate is common across other pharmacy journals. PMID:28042357

    2015-01-01

    Filling a needed scholarly publishing avenue for astronomy education researchers and earth science education researchers, the Journal of Astronomy & Earth Sciences Education - JAESE published its first volume and issue in 2014. The Journal of Astronomy & Earth Sciences Education - JAESE is a scholarly, peer-reviewed scientific journal publishing original discipline-based education research and evaluation, with an emphasis of significant scientific results derived from ethical observations and systematic experimentation in science education and evaluation. International in scope, JAESE aims to publish the highest quality and timely articles from discipline-based education research that advance understanding of astronomy and earth sciences education and are likely to have a significant impact on the discipline or on policy. Articles are solicited describing both (i) systematic science education research and (ii) evaluated teaching innovations across the broadly defined Earth & space sciences education, including the disciplines of astronomy, climate education, energy resource science, environmental science, geology, geography, agriculture, meteorology, planetary sciences, and oceanography education. The publishing model adopted for this new journal is open-access and articles appear online in GoogleScholar, ERIC, and are searchable in catalogs of 440,000 libraries that index online journals of its type. Rather than paid for by library subscriptions or by society membership dues, the annual budget is covered by page-charges paid by individual authors, their institutions, grants or donors: This approach is common in scientific journals, but is relatively uncommon in education journals. Authors retain their own copyright. The journal is owned by the Clute Institute of Denver, which owns and operates 17 scholarly journals and currently edited by former American Astronomical Society Education Officer Tim Slater, who is an endowed professor at the University of Wyoming and

  7. Organic contaminants in mountains.

    PubMed

    Daly, Gillian L; Wania, Frank

    2005-01-15

    The study of organic contaminants at high altitudes is motivated by the potential risk that they pose to humans living in, or depending on resources derived from, mountains and to terrestrial and aquatic ecosystems in alpine areas. Mountains are also ideal settings to study contaminant transport and behavior along gradients of climate and surface cover. Information on organic contaminants in mountains is compiled from the literature and synthesized, with a focus on atmospheric transport and deposition, contaminant dynamics in alpine lakes and aquatic organisms, and concentration differences with altitude. Diurnal mountain winds, in connection with enhanced deposition at higher elevations caused by low temperatures and high precipitation rates, conspire to make mid-latitude mountains become convergence zones for selected persistent organic chemicals. In particular, the more volatile constituents of contaminant mixtures seem to become enriched, relative to the less volatile constituents at higher altitudes. For selected contaminants, concentration inversions (i.e., concentrations that increase with elevation) have been observed. A notable difference between cold trapping in high latitudes and high altitudes is the likely importance of precipitation. High rates of snow deposition in mid- and high-latitude mountains may lead to a large contaminant release during snowmelt. Regions above the tree line often have little capacity to retain the released contaminants, suggesting the potential for a highly dynamic contaminant fate situation during the snow-free season with significant revolatilization and runoff. The chemical and environmental factors that control the orographic cold trapping of organic contaminants should be examined further by measuring and comparatively interpreting concentration gradients along several mountain slopes with widely different characteristics. Future efforts should further focus on the bioaccumulation and potential effects of contaminants in

    The scale of land-contamination problems, and of the responses to them, makes achieving sustainability in contaminated land remediation an important objective. The Sustainable Remediation Forum in the UK (SuRF-UK) was established in 2007 to support more sustainable remediation practice in the UK. The current international interest in 'sustainable remediation' has achieved a fairly rapid consensus on concepts, descriptions and definitions for sustainable remediation, which are now being incorporated into an ISO standard. However the sustainability assessment methods being used remain diverse with a range of (mainly) semi-quantitative and quantitative approaches and tools developed, or in development. Sustainability assessment is site specific and subjective. It depends on the inclusion of a wide range of considerations across different stakeholder perspectives. Taking a tiered approach to sustainability assessment offers important advantages, starting from a qualitative assessment and moving through to semi-quantitative and quantitative assessments on an 'as required' basis only. It is also clear that there are a number of 'easy wins' that could improve performance against sustainability criteria right across the site management process. SuRF-UK has provided a checklist of 'sustainable management practices' that describes some of these. This paper provides the rationale for, and an outline of, and recently published SuRF-UK guidance on preparing for and framing sustainability assessments; carrying out qualitative sustainability assessment; and simple good management practices to improve sustainability across contaminated land management activities.

    Mycotoxins represent a risk to the feed supply chain with an impact on economies and international trade. A high percentage of feed samples have been reported to be contaminated with more than one mycotoxin. In most cases, the concentrations were low enough to ensure compliance with the European Union (EU) guidance values or maximum admitted levels. However, mycotoxin co-contamination might still exert adverse effects on animals due to additive/synergistic interactions. Studies on the fate of mycotoxins during cereal processing, such as milling, production of ethanol fuels, and beer brewing, have shown that mycotoxins are concentrated into fractions that are commonly used as animal feed. Published data show a high variability in mycotoxin repartitioning, mainly due to the type of mycotoxins, the level and extent of fungal contamination, and a failure to understand the complexity of food processing technologies. Precise knowledge of mycotoxin repartitioning during technological processes is critical and may provide a sound technical basis for feed managers to conform to legislation requirements and reduce the risk of severe adverse market and trade repercussions. Regular, economical and straightforward feed testing is critical to reach a quick and accurate diagnosis of feed quality. The use of rapid methods represents a future challenge. PMID:26891326

This article describes some of the issues that are facing scientific publishers, and shows some examples of what one of the commercial publishers, Springer, has done and is working on, in order to stay abreast of these changes and to embrace the new technologies that become available. Springer has moved rapidly into the digital age and has by now digitized almost all its journal content and a significant part of its book content. We have developed new capabilities that make use of the new technologies available and are in the process of further utilizing these new possibilities. Web products like AuthorMapper, SpringerProtocols, and Social Networking sites explore some of these new capabilities. We will continue to explore enhancements of our scientific publishing efforts to provide new possibilities for communicating scientific research.

    Phytostabilization aims to immobilize soil contaminants using higher plants. The accumulation of trace elements in Populus alba leaves was monitored for 12 years after a mine spill. Concentrations of As and Pb significantly decreased, while concentrations of Cd and Zn did not significantly over time. Soil concentrations extracted by CaCl2 were measured by ICP-OES and results of As and Pb were below the detection limit. Long-term biomonitoring of soil contamination using poplar leaves was proven to be better suited for the study of trace elements. Plants suitable for phytostabilization must also be able to survive and reproduce in contaminated soils. Concentrations of trace elements were also measured in P. alba fruiting catkins to determine the effect on its reproduction potential. Cadmium and Zn were found to accumulate in fruiting catkins, with the transfer coefficient for Cd significantly greater than Zn. It is possible for trace elements to translocate to seed, which presents a concern for seed germination, establishment and colonization. We conclude that white poplar is a suitable tree for long-term monitoring of soil contaminated with Cd and Zn, and for phytostabilization in riparian habitats, although some caution should be taken with the possible effects on the food web.

    The current dramatic evolution in information technology is bringing major modifications in the way scientists work and communicate. The concept of electronic information handling encompasses the diverse types of information, the different media, as well as the various communication methodologies and technologies. It ranges from the very collection of data until the final publication of results and sharing of knowledge. New problems and challenges result also from the new information culture, especially on legal, ethical, and educational grounds. Electronic publishing will have to diverge from an electronic version of contributions on paper and will be part of a more general flexible-publishing policy. The benefits of private publishing are questioned. The procedures for validating published material and for evaluating scientific activities will have to be adjusted too. Provision of electronic refereed information independently from commercial publishers in now feasible. Scientists and scientific institutions have now the possibility to run an efficient information server with validated (refereed) material without the help of a commercial publishers.

The CAU can be used to decontaminate and decommission hazardous and radioactive surfaces by measuring residual hazardous surface contamination, such as tritium and trace organics. It provides surface contamination data for research and development applications as well as real-time process control feedback for industrial cleaning operations and can be used to determine the readiness of a surface to accept bonding or coatings. 1 fig.

    An apparatus and method for in situ remediation of contaminated subsurface soil or groundwater contaminated by chlorinated hydrocarbons. A nutrient fluid is selected to stimulate the growth and reproduction of indigenous subsurface microorganisms that are capable of degrading the contaminants; an oxygenated fluid is selected to create a generally aerobic environment for these microorganisms to degrade the contaminants, leaving only pockets that are anaerobic. The nutrient fluid is injected periodically while the oxygenated fluid is injected continuously and both are extracted so that both are drawn across the plume. The nutrient fluid stimulates microbial colony growth; withholding it periodicially forces the larger, healthy colony of microbes to degrade the contaminants. Treatment is continued until the subsurface concentration of contaminants is reduced to an acceptable, preselected level. The nutrient fluid can be methane and the oxygenated fluid air for stimulating production of methanotrophs to break down chlorohydrocarbons, especially trichloroethylene (TCE) and tetrachloroethylene.

    Tobacco dependence, considered for a long time as a habit and, more recently, as an addiction, has many bad effects in health. The objective of this study was to analyse books published in this field in Spain. Books indexed in the ISBN Spanish database in CD-ROM (updated to 1993) dealing with addiction to tobacco, that included one of the following words: tabac*, tabak*, tabaq*, fuma*, fumad*, nicotine*, alquitran*, antitabac*, antitabaq*, cigarro*, cigarri*, exfumad*, pipa*, puro*, picadura* or filtro, were included in the study. Authors, ISBN classification, year of publication, language (of publication and original) and publishers were descriptively analysed. One hundred and four books were analysed. The highest number was published during the period 1990-1993 (42%); being 1993 (n = 15) and 1991 (n = 14) the most productive years. A big increase was observed from 1985. A great number (76% of books, n = 79) was written by personal authors and the 14% (n = 14) by public organizations. Most of the books (n = 88; 85%); were published in Spanish, followed by Catalan (n = 13; 13%); 21 books (20%) were translations: most of them from English (n = 12; 60%) or from French (n = 3; 14%). Forty six per cent of books was published by trade publishers and 31% by public organizations. According to the ISBN classification, these books were grouped in 20 different topics; but, most of them (70%) were included in three of these topics: hygiene (n = 42, 40%), pharmacology-toxicology-drugs (n = 18, 17%) and pathology-diseases and medical/therapeutical clinical practice (n = 14; 13%). The number of books published in Spain dealing with tobacco dependence has increased very much from 1985; it suggests that interest in this area in SPain has also increased. Most of the books are published in Spanish, and the most frequently translated language is English. These books are basically published by trade publishers and public organizations. These results have to be considered taking into

  3. Soil contamination standards for protection of personnel

    Rittmann, P.D.

    1998-04-16

    The objective of this report is to recommend soil contamination levels that will ensure that radionuclide intakes by unprotected workers are likely to give internal doses below selected dose limits during the working year. The three internal dose limits are 1, 100, and 500 mrem per year. In addition, photon, beta, and alpha instrument readings are estimated for these soil concentration limits. Two exposure pathways are considered: the first is inhalation of resuspended dust and the second is ingestion of trace amounts of soil. In addition, radioactive decay and ingrowth of progeny during the year of exposure is included. External dose from the soil contamination is not included because monitoring and control of external exposures is carried out independently from internal exposures, which are the focus of this report. The methods used are similar to those used by Carbaugh and Bihl (1993) to set bioassay criteria for such workers.

    The contemporary radiation doses to the organs and tissues of murine rodents inhabiting the most contaminated part of the EURT were estimated. The bones of animals trapped in 2005 at territories with a surface (90)Sr contamination of 24-40 MBq/m(2) were used for dose reconstruction. The concentration of (90)Sr in the animals' skulls was measured using the nondestructive method of bone radiometry. The dose estimation procedure included application of the published values of absorbed fractions of beta-radiation energy for different combinations of source and target organs, accounting for the distribution of radionuclide by organs and tissues. Twelve conversion coefficients were obtained to link the skeleton (90)Sr concentration and doses to eleven organs and the whole body. The whole-body dose rate on the 45th day after the beginning of exposure normalised to whole-body activity is 0.015 (mGy day(-1))/(Bq g(-1)). The estimation yields the following values of doses for Microtus agrestis, Sylvaemus uralensis and Clethrionomys rutilus, respectively: maximum absorbed doses in the skeleton: 267, 121 and 160 mGy; mean whole body internal doses: 37, 14 and 23 mGy; mean internal dose rates on the last day before trapping: 1.2; 0.44 and 0.75 mGy/day. Approaches to the assessment of doses to foetuses and to offspring before weaning were also developed.

    This satellite symposium was the fifth in a series for editors, publishers, reviewers and all those with an interest in scientific publishing. It was held on Wednesday, 11 March 2015 at the IADR meeting in Boston, Massachusetts. The symposium attracted more than 210 attendees. The symposium placed an emphasis on strategies to ensure that papers are accepted by peer reviewed journals. The speaker, representing the Journal of Dental Research gave a history of peer review and explained how to access material to advise new authors. The speaker from India outlined the problems that occur when there is no culture for dental research and it is given a low priority in dental education. He outlined remedies. The speaker from SAGE publications described the help that publishers and editors can provide authors. The final speaker suggested that in developing countries it was essential to create alliances with dental researchers in developed countries and that local conferences to which external speakers were invited, stimulated research both in terms of quantity and quality. A wide ranging discussion then took place.

    The ubiquity and resilience of microorganisms makes them unavoidable in most environments including space habitats. The impaired immune system of astronauts in flight raises the level of concern about disease risk during human space missions and additionally these biological contaminants may affect life support systems and hardware. In this review, the microbial contamination observed in manned space stations and in particular the International Space Station ISS will be discussed, demonstrating that it is a microbiologically safe working and living habitat. Microbial contamination levels were in general below the implemented quality standards, although, occasional contamination hazard reports indicate that the current prevention and monitoring strategies are the strict minimum.

  9. Contamination and UV lasers: lessons learned

    NASA Astrophysics Data System (ADS)

    Daly, John G.

    2015-09-01

    Laser induced damage to optical elements has been a subject of significant research, development, and improvement, since the first lasers were built over the last 50 years. Better materials, with less absorption, impurities, and defects are available, as well as surface coatings with higher laser damage resistance. However, the presence of contamination (particles, surface deposition films, or airborne) can reduce the threshold for damage by several orders of magnitude. A brief review of the anticipated laser energy levels for damage free operation is presented as a lead into the problems associated with contamination for ultraviolet (UV) laser systems. As UV lasers become more common in applications especially in areas such as lithography, these problems have limited reliability and added to costs. This has been characterized as Airborne Molecular Contamination (AMC) in many published reports. Normal engineering guidelines such as screening materials within the optical compartment for low outgassing levels is the first step. The use of the NASA outgassing database (or similar test methods) with low Total Mass Loss (TML) and Condensed Collected Volatiles Collected Mass (CVCM) is a good baseline. Energetic UV photons are capable of chemical bond scission and interaction with surface contaminant or airborne materials results in deposition of obscuring film laser footprints that continue to degrade laser system performance. Laser systems with average powers less than 5 mW have been shown to exhibit aggressive degradation. Lessons learned over the past 15 years with UV laser contamination and steps to reduce risk will be presented.

    The large-scale industrial production and processing of munitions such as 2,4,6-trinitrotoluene (TNT) over the past 100 years led to the disposal of wastes containing explosives and nitrated organic by-products into the environment. In the US, the Army alone has estimated that over 1.2 million tons of soil have been contaminated with explosives, and the impact of explosives contamination in other countries is of similar magnitude. In recent years, growing concern about the health and ecological threats posed by man-made chemicals have led to studies of the toxicology of explosives, which have identified toxic and mutagenic effects of the common military explosives and their transformation products (Bruns-Nagel et al., 1999a; Fuchs et al., 2001; Homma-Takeda et al., 2002; Honeycutt et al., 1996; Rosenblatt et al., 1991; Spanggord et al., 1982; Tan et al., 1992 and Won et al., 1976). Because the cleanup of areas contaminated by explosives is now mandated because of public health concerns, considerable effort has been invested in finding economical remediation technologies. Biological treatment processes are often considered, since these are usually the least expensive means of destroying organic pollution. This review examines the most important groups of chemicals that must be treated at sites contaminated by explosives processing, the chemical and biological transformations they undergo, and commercial processes developed to exploit these transformations for treatment of contaminated soil. We critically examine about 150 papers on the topic, including approximately 60 published within the past 5 years.

    Soil contaminated by polychlorinated biphenyls (PCBs) is a ubiquitous problem in the world, which can cause significant risks to human health and the environment. Mechanochemical destruction (MCD) has been recognized as a promising technology for the destruction of persistent organic pollutants (POPs) and other organic molecules in both solid waste and contaminated soil. However, few studies have been published about the application of MCD technology for the remediation of PCB contaminated soil. In the present study, the feasibility of destroying PCBs in contaminated soil by co-grinding with and without additives in a planetary ball mill was investigated. After 4 h milling time, more than 96% of PCBs in contaminated soil samples were destroyed. The residual concentrations of PCBs decreased from 1000 mg/kg to below the provisional Basel Convention limit of less than 50 mg/kg. PCDD/F present in the original soil at levels of 4200 ng TEQ/kg was also destroyed with even a slightly higher destruction efficiency. Only minor dechlorinations of the PCBs were observed and the destruction of the hydrocarbon skeleton is proposed as the main degradation pathway of PCBs.

    This paper summarizes the correlation study between contamination and scratches on singlemode APC connectors and signal degradation; leading to an Acceptance Criteria Matrix. The study is a continuation of International Electronics Manufacturing Initiative (iNEMI) research on development of cleanliness specification for singlemode angled physical contact (SM-APC) connectors. Twenty-five APC SC connectors on one-meter patch cords were used for this study. The Design of the Experiment (DoE) was a multi-step process that involved: (1) inspecting, cleaning and inspecting connectors being tested (devices under test, or DUTs) and launch connectors; (2) making multiple matings and dematings of each DUT, in a pristine state, with a reference connector, and recording Return Loss (RL) data after each cycle; (3) manually applying dust to the cleaned end-faces of the DUTs; then (4) mating contaminated DUTs with clean reference connectors at least five times, taking RL measurements after each mating and saving fiber end-face images for both connectors. It was shown that connectors with the contamination at the core (9um diameter) demonstrated a dramatic decrease in average RL of 14.2 dB. In comparison, the samples with contamination on the cladding and clear core demonstrated a negligible change in RL of 0.15 dB. For highly contaminated samples in the cladding layer, we found the changes of RL to be about 5-6 dB. Further investigation established that particle migration during successive matings also occurs on the ferrule within the contact zone (approximately <250 μm in diameter). Polishing scratches had no impact on RL of APC connectors. Based on the experimental data described in this paper, an inspection criteria matrix is proposed for SM-APC connectors including the zone definitions and number of allowable defects (contamination and scratches) for each zone. The recommendations on pass/fail criteria have been provided to the IEC (International Electrotechnical Committee

    This study evaluated the use de standards in papers published in Brazilian and international dental journals. Papers published from January 2006 to December 2010 in the following journals were examined: Brazilian Dental Journal (BDJ), Brazilian Oral Research (BOR), Journal of Applied Oral Sciences (JAOS), Journal of Dental Research (JDR) and Dental Materials (DM). In addition to the title and type of study, issue, volume and year of publication, the following information was recorded from each paper: identification of any standard reported in the study; in case of no reported standard, indication if a standard could be used in the study. A total of 3,046 papers were examined, being 937 from DM, 936 from JDR, 489 from JAOS, 348 from BDJ, and 336 from BOR. Considering the papers that could use some standard, DM showed the highest percentage (24.9%) of reporting standards/paper, followed by JAOS (10.3%), BOR (10.1%), BDJ (6.3%) and JDR (2.4%), meaning for example that, from 936 papers examined from the JDR, 623 could use some standard but only 15 papers reported them. From all papers examined, 309 (10.1%) reported using some standard. The ISO standards were mostly reported (57.8%), followed by ASTM standards (23.7%) and 74 (18.5%) standards from other international organizations (e.g. ADA and CIE). Despite of the high impact factors of the selected dental journals, their published papers could use standards more often. This study should assist journal editors to encourage authors to consult and refer to available standards to support the scientific papers.

    Writing a paper for publication in a peer-reviewed journal is a rewarding experience but a very difficult undertaking that requires years of experience, determination and patience. The exponential rise of knowledge has resulted in the exponential rise of manuscripts submitted for publication in the various peer-reviewed journals all over the world. Potential authors are not only having to write high-quality papers to get published, but also have to compete with other authors for the limited journal space available to publish their papers. The purpose of this article is to highlight some of the ways of making the task of getting published in peer-reviewed journals easier to achieve.

  16. Electronic Publishing or Electronic Information Handling?

    NASA Astrophysics Data System (ADS)

    Heck, A.

    The current dramatic evolution in information technology is bringing major modifications in the way scientists communicate. The concept of 'electronic publishing' is too restrictive and has often different, sometimes conflicting, interpretations. It is thus giving way to the broader notion of 'electronic information handling' encompassing the diverse types of information, the different media, as well as the various communication methodologies and technologies. New problems and challenges result also from this new information culture, especially on legal, ethical, and educational grounds. The procedures for validating 'published material' and for evaluating scientific activities will have to be adjusted too. 'Fluid' information is becoming a common concept. Electronic publishing cannot be conceived without link to knowledge bases nor without intelligent information retrieval tools.

    Open-access journal publishing has significantly grown in recent years. Restricted access publications have, in turn, increasing access costs as they benefit from a unique economic model in which relevant work and essential inputs are provided free of charge to vendors who have a captive market that has almost no competition. An additional issue typical of industries that work under the copyright regime is that the oligopoly market structure of the publishing industry which in turn further contributes to increase their products' prices. Mandatory open-access policies, as determined by the NIH, constitute a threat to this business model and are being challenged by the industry on several fronts, including the passage of legislation to undermine these initiatives. The purpose of this commentary article was to review key aspects of this confrontation and to suggest potential strategies for encouraging open-access publishing in Brazil.

    This compilation was designed to help U.S. Fish and Wildlife Service contaminant specialists evaluate the degree of contamination of a soil, based on chemical analyses. Included are regulatory criteria, opinions, brief descriptions of scientific articles, and miscellaneous information that might be useful in making risk assessments. The intent was to make hard-to-obtain material readily available to contaminant specialists, but not to critique the material or develop new criteria. The compilation is to be used with its index, which includes about 200 contaminants. There are several entries for a few of the most thoroughly studied contaminants, but for most of them the information available is meager. Entries include soil contaminant criteria from other countries, contaminant guidelines for applying sewage sludge to soil, guidelines for evaluating sediments, background soil concentrations for various elements, citations to scientific articles that may help estimate the potential movement of soil contaminants into wildlife food chains, and a few odds and ends. Articles on earthworms were emphasized because they are a natural bridge between soil and many species of wildlife.

    This article overviews unethical publishing practices in connection with the pressure to publish more. Both open-access and subscription publishing models can be abused by ‘predatory’ authors, editors, and publishing outlets. Relevant examples of ‘prolific’ scholars are viewed through the prism of the violation of ethical authorship in established journals and indiscriminately boosting publication records elsewhere. The instances of ethical transgressions by brokering editorial agencies and agents, operating predominantly in non-Anglophone countries, are presented to raise awareness of predatory activities. The scheme of predatory publishing activities is presented, and several measures are proposed to tackle the issue of predatory publishing. The awareness campaigns by professional societies, consultations with information facilitators, implementation of the criteria of best target journals, and crediting of scholars with use of integrative citation metrics, such as the h-index, are believed to make a difference.

  2. Space Stirling Cryocooler Contamination Lessons Learned and Recommended Control Procedures

    Glaister, D. S.; Price, K.; Gully, W.; Castles, S.; Reilly, J.

    The most important characteristic of a space cryocooler is its reliability over a lifetime typically in excess of 7 years. While design improvements have reduced the probability of mechanical failure, the risk of internal contamination is still significant and has not been addressed in a consistent approach across the industry. A significant fraction of the endurance test and flight units have experienced some performance degradation related to internal contamination. The purpose of this paper is to describe and assess the contamination issues inside long life, space cryocoolers and to recommend procedures to minimize the probability of encountering contamination related failures and degradation. The paper covers the sources of contamination, the degradation and failure mechanisms, the theoretical and observed cryocooler sensitivity, and the recommended prevention procedures and their impact. We begin with a discussion of the contamination sources, both artificial and intrinsic. Next, the degradation and failure mechanisms are discussed in an attempt to arrive at a contaminant susceptibility, from which we can derive a contamination budget for the machine. This theoretical sensitivity is then compared with the observed sensitivity to illustrate the conservative nature of the assumed scenarios. A number of lessons learned on Raytheon, Ball, Air Force Research Laboratory, and NASA GSFC programs are shared to convey the practical aspects of the contamination problem. Then, the materials and processes required to meet the proposed budget are outlined. An attempt is made to present a survey of processes across industry.

  3. Electronic publishing and intelligent information retrieval

    Heck, A.

    1992-01-01

    Europeans are now taking steps to homogenize policies and standardize procedures in electronic publishing (EP) in astronomy and space sciences. This arose from an open meeting organized in Oct. 1991 at Strasbourg Observatory (France) and another business meeting held late Mar. 1992 with the major publishers and journal editors in astronomy and space sciences. The ultimate aim of EP might be considered as the so-called 'intelligent information retrieval' (IIR) or better named 'advanced information retrieval' (AIR), taking advantage of the fact that the material to be published appears at some stage in a machine-readable form. It is obvious that the combination of desktop and electronic publishing with networking and new structuring of knowledge bases will profoundly reshape not only our ways of publishing, but also our procedures of communicating and retrieving information. It should be noted that a world-wide survey among astronomers and space scientists carried out before the October 1991 colloquium on the various packages and machines used, indicated that TEX-related packages were already in majoritarian use in our community. It has also been stressed at each meeting that the European developments should be carried out in collaboration with what is done in the US (STELLAR project, for instance). American scientists and journal editors actually attended both meetings mentioned above. The paper will offer a review of the status of electronic publishing in astronomy and its possible contribution to advanced information retrieval in this field. It will also report on recent meetings such as the 'Astronomy from Large Databases-2 (ALD-2)' conference dealing with the latest developments in networking, in data, information, and knowledge bases, as well as in the related methodologies.

    An examination of top-cited articles is a tool that can be used to identify and monitor outstanding scientific research. The goal of this study was to identify and analyze the characteristics of the 100 top-cited articles published in international journals dedicated to psychiatry. The Science Citation Index Expanded provided by the Thomson Reuters Institute for Scientific Information Web of Knowledge was searched in December, 2011, and 128 journals were identified in the subject category "Psychiatry." Each journal was searched on the Web of Science under "Publication Name" and the results were sorted by category "Times Cited." The 100 top-cited articles were recorded, and the list was analyzed with regard to journals, number of citations, authors, year, institution, and country of origin. The original research articles of the 100 top-cited articles were classified into one of five categories: scale/measurement, descriptive/epidemiology, mechanism, management, and imaging. The 100 top-cited articles were cited between 26,578 and 781 times; they were published between 1957 and 2005, with the largest number (35) published in the 1990s. The articles appeared in 24 journals, with more than half published in the Archives of General Psychiatry (56), followed by the American Journal of Psychiatry (6), and Psychological Medicine (6). Articles that dealt with the development, application, or validity of measurements led the list of top-cited psychiatric publications (43) and had a significantly higher number of citations compared with the rest of the articles. The time and language of publication, field of study, country of origin, and journal in which the paper appeared are possible determinants of the likelihood of citation and impact.

  6. Contaminated water treatment

    Gormly, Sherwin J. (Inventor); Flynn, Michael T. (Inventor)

    2010-01-01

    Method and system for processing of a liquid ("contaminant liquid") containing water and containing urine and/or other contaminants in a two step process. Urine, or a contaminated liquid similar to and/or containing urine and thus having a relatively high salt and urea content is passed through an activated carbon filter to provide a resulting liquid, to remove most of the organic molecules. The resulting liquid is passed through a semipermeable membrane from a membrane first side to a membrane second side, where a fortified drink having a lower water concentration (higher osmotic potential) than the resulting liquid is positioned. Osmotic pressure differential causes the water, but not most of the remaining inorganic (salts) contaminant(s) to pass through the membrane to the fortified drink. Optionally, the resulting liquid is allowed to precipitate additional organic molecules before passage through the membrane.

  7. Bioremediation of contaminated groundwater

    Hazen, T.C.; Fliermans, C.B.

    1994-01-01

    Disclosed is an apparatus and method for in situ remediation of contaminated subsurface soil or groundwater contaminated by chlorinated hydrocarbons. A nutrient fluid (NF) is selected to simulated the growth and reproduction of indigenous subsurface microorganisms capable of degrading the contaminants; an oxygenated fluid (OF) is selected to create an aerobic environment with anaerobic pockets. NF is injected periodically while OF is injected continuously and both are extracted so that both are drawn across the plume. NF stimulates microbial colony growth; withholding it periodically forces the larger, healthy colony of microbes to degrade the contaminants. Treatment is continued until the subsurface concentration of contaminants is acceptable. NF can be methane and OF be air, for stimulating production of methanotrophs to break down chlorohydrocarbons, especially TCE and tetrachloroethylene.

  10. Behind the Spam: A ``Spectral Analysis'' of Predatory Publishers

    NASA Astrophysics Data System (ADS)

    Beall, Jeffrey

    2016-10-01

    Most researchers today are bombarded with spam email solicitations from questionable scholarly publishers. These emails solicit article manuscripts, editorial board service, and even ad hoc peer reviews. These ``predatory'' publishers exploit the scholarly publishing process, patterning themselves after legitimate scholarly publishers yet performing little or no peer review and quickly accepting submitted manuscripts and collecting fees from submitting authors. These counterfeit publishers and journals have published much junk science? especially in the field of cosmology? threatening the integrity of the academic record. This paper examines the current state of predatory publishing and advises researchers how to navigate scholarly publishing to best avoid predatory publishers and other scholarly publishing-related perils.

    Marušić, Ana

    2014-01-01

    Scientific publishing is rapidly developing from print-only to digital journals and extensive use of social media. This essay presents our experience in developing a small and scholarly journal from the so-called scientific semi-periphery and using the advantages of digital publishing to increase the visibility of the journal in international indexing and citation databases, and ensure greater visibility in the global scientific community. An editor of a scientific journal does not need to master all details of different digital publishing tools, but needs to follow the developments so that they can be best implemented in the journal.

  13. Spacecraft Maximum Allowable Concentrations for Selected Airborne Contaminants. Volume 2

    NASA Technical Reports Server (NTRS)

    1996-01-01

    The National Aeronautics and Space Administration (NASA) is aware of the potential toxicological hazards to humans that might be associated with prolonged spacecraft missions. Despite major engineering advances in controlling the atmosphere within spacecraft, some contamination of the air appears inevitable. NASA has measured numerous airborne contaminants during space missions. As the missions increase in duration and complexity, ensuring the health and well-being of astronauts traveling and working in this unique environment becomes increasingly difficult. As part of its efforts to promote safe conditions aboard spacecraft, NASA requested the National Research Council (NRC) to develop guidelines for establishing spacecraft maximum allowable concentrations (SMACs) for contaminants, and to review SMACs for various space-craft contaminants to determine whether NASA's recommended exposure limits are consistent with the guidelines recommended by the subcommittee. In response to NASA's request, the NRC organized the Subcommittee on Guidelines for Developing Spacecraft Maximum Allowable Concentrations for Space Station Contaminants within the Committee On Toxicology (COT). In the first phase of its work, the subcommittee developed the criteria and methods for preparing SMACs for spacecraft contaminants. The subcommittee's report, entitled Guidelines for Developing Spacecraft Maximum Allowable Concentrations for Space Station Contaminants, was published in 1992. The executive summary of that report is reprinted as Appendix A of this volume. In the second phase of the study, the Subcommittee on Spacecraft Maximum Allowable Concentrations reviewed reports prepared by NASA scientists and contractors recommending SMACs for approximately 35 spacecraft contaminants. The subcommittee sought to determine whether the SMAC reports were consistent with the 1992 guidelines. Appendix B of this volume contains the SMAC reports for 12 chemical contaminants that have been reviewed for

    Central America is recognized as a mega diverse "hot-spot" and one of its smaller countries, Costa Rica, as one of the world's leaders in the study and conservation of tropical biodiversity. For this study, inspired by the 60th anniversary of the journal Revista de Biología Tropical, we tabulated all the scientific production on Costa Rican biodiversity published in Revista de Biología Tropical between 2000 and 2010. Most articles are zoological (62%) and 67% of authors had only one publication in the jounal within that period. A 54% of articles were published in English and 46% in Spanish. A 41% of articles were written in collaboration among Costa Rican institutions and 36% in collaboration with foreign institutions. The Collaboration Index was 2.53 signatures per article. Visibility in American sources was 56% in Google Scholar and 42.66% in the Web of Science, but the real visibility and impact are unknown because these sources exclude the majority of tropical journals. Revista de Biología Tropical is the main output channel for Costa Rican biology and despite its small size, Costa Rica occupies the 10th. place in productivity among Latin American countries, with productivity and impact levels that compare favorably with larger countries such as Brazil, Mexico, Argentina and Chile.

  18. The earliest published electrocardiogram showing ventricular preexcitation.

    PubMed

    Von Knorre, Georg H

    2005-03-01

    When in 1930, Wolff, Parkinson, and White published what is today known as the WPW, or preexcitation syndrome, they, and subsequently others, found few comparable cases in the preceding literature. Among these the report of Cohn and Fraser, published in 1913, was the earliest. However, another even earlier documentation in a 1909 article by Hoffmann escaped notice till now. The ECG of a patient with paroxysmal tachycardia reveals a short PR interval and a delta-wave-induced widening of the QRS complex, even though the reproduced tachycardia was not preexcitation related. The interpretation of this poorly reproduced ECG can be confirmed by another and more detailed description of the patient in an electrocardiography textbook published in 1914 by the same author. Thus, the earliest publication of an ECG showing ventricular preexcitation now can be dated back to 1909. Moreover, the Hoffmann monograph contains two additional examples of the WPW syndrome not noticed until now. All three cases published by Hoffmann had their first ECG recordings in 1912 or earlier.

    As a result of reviewing several aspects of our content, both in print and online, we have made some changes for 2008. These changes are described below. Article numbering Inverse Problems has moved from sequential page numbering to an article numbering system, offering important advantages and flexibility by speeding up the publication process. Articles in different issues or sections can be published online as soon as they are ready, without having to wait for a whole issue or section to be allocated page numbers. The bibliographic citation will change slightly. Articles should be referenced using the six-digit article number in place of a page number, and this number must include any leading zeros. For instance: Surname X and Surname Y 2008 Inverse Problems 24 015001 Articles will continue to be published on the web in advance of the print edition. A new look and feel We have taken the opportunity to refresh the design of Inverse Problems' cover in order to modernise the typography and create a consistent look and feel across IOP Publishing's range of publications.

    2014-05-01

    As data publishing journals - Earth System Science Data (ESSD, Copernicus, since 2009), Geophysical Data Journal (GDJ, Wiley, recent) and Scientific Data (SD, Nature Publishing Group, anticipated from May 2014) - expose data sets, implement data description and data review practices, and develop partnerships with data centres and data providers, we anticipate substantial benefits for the broad earth system and environmental research communities but also substantial challenges for all parties. A primary advantage emerges from open access to convergent data: subsurface hydrographic data near Antarctica, for example, now available for combination and comparison with nearby atmospheric data (both documented in ESSD), basin-scale precipitation data (accessed through GDJ) for comparison and interpolation with long-term global precipitation records (accessed from ESSD), or, imagining not too far into the future, stomach content and abundance data for European fish (from ESSD) linked to genetic or nutritional data (from SD). In addition to increased opportunity for discovery and collaboration, we also notice parallel developments of new tools for (published) data visualization and display and increasing acceptance of data publication as a useful and anticipated dissemination step included in project- and institution-based data management plans. All parties - providers, publishers and users - will benefit as various indexing services (SCI, SCOPUS, DCI etc.) acknowledge the creative, intellectual and meritorious efforts of data preparation and data provision. The challenges facing data publication, in most cases very familiar to the data community but made more acute by the advances in data publishing, include diverging metadata standards (among biomedical, green ocean modeling and meteorological communities, for example), adhering to standards and practices for permanent identification while also accommodating 'living' data, and maintaining prompt but rigorous review and

  7. Blood culture contaminants.

    PubMed

    Dawson, S

    2014-05-01

    Blood cultures are an essential diagnostic tool. However, contamination may impact on patients' care and lead to increased patient stay, additional tests, and inappropriate antibiotic use. The aim of this study was to review the literature for factors that influence the rate of blood culture contamination. A comprehensive literature search was performed using Medline and CINAHL on blood culture contamination. Hospitals/units should have in place a protocol for staff on how to take blood cultures, incorporating use of an aseptic technique. Studies have shown that several key factors in the process may lower contamination rates such as adherence to a protocol, sampling by peripheral venepuncture route rather than via an intravascular catheter, use of sterile gloves, cleaning tops of blood culture bottles with antiseptics and inoculating blood culture bottles before other blood tubes, samples being taken by a phlebotomy team, monitoring contamination rates, and providing individual feedback and retraining for those with contaminants. Although skin antisepsis is advocated there is still debate on which antiseptic is most effective, as there is no conclusive evidence, only that there is benefit from alcohol-containing preparations. In conclusion, hospitals should aim to minimize their blood culture contamination rates. They should monitor their rate regularly and aim for a rate of ≤3%.

  8. Subsurface contaminants focus area

    SciTech Connect

    1996-08-01

    The US Department of Enregy (DOE) Subsurface Contaminants Focus Area is developing technologies to address environmental problems associated with hazardous and radioactive contaminants in soil and groundwater that exist throughout the DOE complex, including radionuclides, heavy metals; and dense non-aqueous phase liquids (DNAPLs). More than 5,700 known DOE groundwater plumes have contaminated over 600 billion gallons of water and 200 million cubic meters of soil. Migration of these plumes threatens local and regional water sources, and in some cases has already adversely impacted off-site rsources. In addition, the Subsurface Contaminants Focus Area is responsible for supplying technologies for the remediation of numerous landfills at DOE facilities. These landfills are estimated to contain over 3 million cubic meters of radioactive and hazardous buried Technology developed within this specialty area will provide efective methods to contain contaminant plumes and new or alternative technologies for development of in situ technologies to minimize waste disposal costs and potential worker exposure by treating plumes in place. While addressing contaminant plumes emanating from DOE landfills, the Subsurface Contaminants Focus Area is also working to develop new or alternative technologies for the in situ stabilization, and nonintrusive characterization of these disposal sites.

    Here, the international Muon Ionization Cooling Experiment (MICE) will perform a systematic investigation of ionization cooling with muon beams of momentum between 140 and 240\\,MeV/c at the Rutherford Appleton Laboratory ISIS facility. The measurement of ionization cooling in MICE relies on the selection of a pure sample of muons that traverse the experiment. To make this selection, the MICE Muon Beam is designed to deliver a beam of muons with less than $\\sim$1% contamination. To make the final muon selection, MICE employs a particle-identification (PID) system upstream and downstream of the cooling cell. The PID system includes time-of-flight hodoscopes, threshold-Cherenkov counters and calorimetry. The upper limit for the pion contamination measured in this paper is $f_\\pi < 1.4\\%$ at 90% C.L., including systematic uncertainties. Therefore, the MICE Muon Beam is able to meet the stringent pion-contamination requirements of the study of ionization cooling.

    The international Muon Ionization Cooling Experiment (MICE) will perform a systematic investigation of ionization cooling with muon beams of momentum between 140 and 240 MeV/c at the Rutherford Appleton Laboratory ISIS facility. The measurement of ionization cooling in MICE relies on the selection of a pure sample of muons that traverse the experiment. To make this selection, the MICE Muon Beam is designed to deliver a beam of muons with less than ~1% contamination. To make the final muon selection, MICE employs a particle-identification (PID) system upstream and downstream of the cooling cell. The PID system includes time-of-flight hodoscopes, threshold-Cherenkov counters and calorimetry. The upper limit for the pion contamination measured in this paper is fπ < 1.4% at 90% C.L., including systematic uncertainties. Therefore, the MICE Muon Beam is able to meet the stringent pion-contamination requirements of the study of ionization cooling.

  15. Use of ATP bioluminescence for assessing the cleanliness of hospital surfaces: a review of the published literature (1990-2012).

    Hospital cleanliness tends to be considered by patients and the public as an important indicator of the general quality of healthcare. Tests for detecting the presence of adenosine triphosphate (ATP) as a proxy of microbial contamination are increasing in popularity, and several studies have been conducted on this topic in the last few decades. The aim of the present study was to review the published literature on this topic and summarize and discuss the available results. The review focused on relevant English-language articles that were identified through searches of two databases [PubMed and Scopus (1990-2012)] by using the keywords "ATP", "bioluminescence", "hospital", and "surfaces". Twelve articles were included and analyzed. ATP measurements showed a wide variation, with values ranging from 0 to >500,000 relative light units (RLU)/s before cleaning and from 3 to 500,000RLU/s after cleaning. ATP benchmarks used by authors ranged from 100 to 500RLU/s. The percentage of surfaces exceeding the chosen cut-off limit showed a failure rate varying from 21.2% to 93.1% before cleaning and from 5.3% to 96.5% after cleaning. Although the use of ATP bioluminescence can be considered a quick and objective method for assessing hospital cleanliness, it appears to be still poorly standardized at both the national and international level.

  16. Publishing bioethics and bioethics--reflections on academic publishing by a journal editor.

    2011-02-01

    This article by one of the Editors of Bioethics, published in the 25th anniversary issue of the journal, describes some of the revolutionary changes academic publishing has undergone during the last decades. Many humanities journals went from typically small print-runs, counting by the hundreds, to on-line availability in thousands of university libraries worldwide. Article up-take by our subscribers can be measured efficiently. The implications of this and other changes to academic publishing are discussed. Important ethical challenges need to be addressed in areas such as the enforcement of plagiarism-related policies, the so-called 'impact factor' and its impact on academic integrity, and the question of whether on-line only publishing can currently guarantee the integrity of academic publishing histories.

  17. Air cleaning issues with contaminated sites

    Bellamy, R.R.

    1997-08-01

    The US Nuclear Regulatory Commission has developed a list of contaminated sites that warrant special USNRC attention because they pose unique or complex decommissioning issues. This list of radiologically contaminated sites is termed the Site Decommissioning Management Plan (SDMP), and was first issued in 1990. A site is placed on the SDMP list if it has; (1) Problems with the viability of the responsible organization (e.g., the licensee for the site is unable or unwilling to pay for the decommissioning); (2) Large amounts of soil contamination or unused settling ponds or burial grounds that may make the waste difficult to dispose of; (3) The long-term presence of contaminated, unused buildings; (4) A previously terminated license; or (5) Contaminated or potential contamination of the ground water from on-site wastes. In deciding whether to add a site to the SDMP list, the NRC also considers the projected length of time for decommissioning and the willingness of the responsible organization to complete the decommissioning in a timely manner. Since the list was established, 9 sites have been removed from the list, and the current SDMP list contains 47 sites in 11 states. The USNRC annually publishes NUREG-1444, {open_quotes}Site Decommissioning Management Plan{close_quotes}, which updates the status of each site. This paper will discuss the philosophical goals of the SDMP, then will concentrate on the regulatory requirements associated with air cleaning issues at the SDMP sites during characterization and remediation. Both effluent and worker protection issues will be discussed. For effluents, the source terms at sites will be characterized, and measurement techniques will be presented. Off-site dose impacts will be included. For worker protection issues, air sampling analyses will be presented in order to show how the workers are adequately protected and their doses measured to satisfy regulatory criteria during decontamination operations. 1 tab.

    2012-01-01

    To address the issue of harmonization of Russian MRLs for tetracycline in food and on the basis of the tasks of preserving the value of hygienic standard for the more restrictive level than similar standards of the Codex Alimentarius Commission in this survey we analyzed the evidences of the negative effects of subingibitory amounts of these antibiotics (lying below the MIC for clinically relevant microorganisms). The inadequacy of the microbiological JECFA ADI and the necessity of using of methodology of analyzing the effects of biological active substances in small doses for assessing the risk of food contamination of tetracycline subingibitory concentrations were demonstrated. Current scientific information on the functions of antibiotics as signaling molecules in the microbial world and the role of tetracycline as a leading factor in the regulation of transcription in microorganisms and activation of the horizontal transfer of resistance genes transferred to the family of conjugative transposons Tn916-Tn1545 also was reviewed in paper. Evidence-based data regarding the basic contribution of subingibitory concentrations of tetracycline in the spread of worst transmissible type of antibiotic resistance and the formation of new pathogens, associated with it, are represented. To reduce the risk of direct adverse effects on microbial ecosystem in the human body and its habitat, and to minimize the indirect risk of new infections, the necessity of saving the current Russian level residues of tetracycline (< or = 0.01 mg/kg of product), which is low by contrast to the Codex MRLs (< or = 0.1-1.2 mg/kg), was proved. Tetracycline concentrations in food, regulated in Russian Federation, below 0.1 MIC for clinically significant microorganisms which aren't capable to initiation of the above described negative changes.

    Data management and data publication are becoming increasingly important components of researcher's workflows. The complexity of managing data, publishing data online, and archiving data has not decreased significantly even as computing access and power has greatly increased. The Open Data Repository's Data Publisher software strives to make data archiving, management, and publication a standard part of a researcher's workflow using simple, web-based tools and commodity server hardware. The publication engine allows for uploading, searching, and display of data with graphing capabilities and downloadable files. Access is controlled through a robust permissions system that can control publication at the field level and can be granted to the general public or protected so that only registered users at various permission levels receive access. Data Publisher also allows researchers to subscribe to meta-data standards through a plugin system, embargo data publication at their discretion, and collaborate with other researchers through various levels of data sharing. As the software matures, semantic data standards will be implemented to facilitate machine reading of data and each database will provide a REST application programming interface for programmatic access. Additionally, a citation system will allow snapshots of any data set to be archived and cited for publication while the data itself can remain living and continuously evolve beyond the snapshot date. The software runs on a traditional LAMP (Linux, Apache, MySQL, PHP) server and is available on GitHub (http://github.com/opendatarepository) under a GPLv2 open source license. The goal of the Open Data Repository is to lower the cost and training barrier to entry so that any researcher can easily publish their data and ensure it is archived for posterity.

    The journal crisis and the demand for free accessibility to the results of publicly funded research were the main drivers of the Open Access movement since the late 1990's. Besides many academic institutions that support the different ways of Open Access publishing, there is a growing number of publishing houses that are specialized on this new access and business model of scholarly literature. The lecture provides an overview of the different kinds of Open Access publishing, discusses the variety of underlying business models, names the advantages and potentials for researches and the public, and overcomes some objections against Open Access. Besides the increased visibility and information supply, the topic of copyrights and exploitation rights will be discussed. Furthermore, it is a central aim of the presentation to show that Open Access does not only support full peer-review, but also provides the potential for even enhanced quality assurance. The financing of business models based on open accessible literature is another important part to be outlined in the lecture.

  10. The ethics of open access publishing.

    PubMed

    Parker, Michael

    2013-03-22

    Should those who work on ethics welcome or resist moves to open access publishing? This paper analyses arguments in favour and against the increasing requirement for open access publishing and considers their implications for bioethics research. In the context of biomedical science, major funders are increasingly mandating open access as a condition of funding and such moves are also common in other disciplines. Whilst there has been some debate about the implications of open-access for the social sciences and humanities, there has been little if any discussion about the implications of open access for ethics. This is surprising given both the central role of public reason and critique in ethics and the fact that many of the arguments made for and against open access have been couched in moral terms. In what follows I argue that those who work in ethics have a strong interest in supporting moves towards more open publishing approaches which have the potential both to inform and promote richer and more diverse forms of public deliberation and to be enriched by them. The importance of public deliberation in practical and applied ethics suggests that ethicists have a particular interest in the promotion of diverse and experimental forms of publication and debate and in supporting new, more creative and more participatory approaches to publication.

  11. Reconditioning contaminated gravel

    Walsh, H.; Bowers, J.S.; Cadwell, K.

    1995-02-01

    Lawrence Livermore National Laboratory (LLNL) has developed a portable screening system that will recondition radioactively contaminated gravel in the field. The separation technique employed by this system removes dirt, contaminated debris, and other fine particles from gravel. At LLNL, gravel is used in conjunction with the experimental testing of explosives to reduce shock wave propagation. The gravel surrounds the experimental device and buffers the energy generated from the explosion. During an explosion, some of the gravel is broken down into small particles and mixed with contaminants. Contaminants in the used gravel originate from metal sheathing and other parts comprising, the experimental device. These contaminants may consist of radionuclides and metals that are considered hazardous by the State of California when disposed. This paper describes the process that conveys contaminated material into the screener system, sprays the material with recycled water or other mild cleaning chemicals, and separates particles based on size. Particles greater than a specified size are discharged out of the screener separator and recycled back into use, thereby reducing the amount of mixed waste generated and minimizing the need for new gravel. The fines or silt are flushed out of the separator with the water and are removed from the water and consolidated into a drum with the use of a hydrocyclone separator and drum decant system. Because the water in the spray system is recycled, minimal makeup water is needed. The system monitors pH and total dissolved solids.

  12. [Chemical food contaminants].

    PubMed

    Schrenk, D

    2004-09-01

    Chemical food contaminants are substances which are neither present naturally in the usual raw material used for food production nor are added during the regular production process. Examples are environmental pollutants or contaminants derived from agricultural production of crops or livestock or from inadequate manufacturing of the food product itself. More difficult is the classification of those compounds formed during regular manufacturing such as products of thermal processes including flavoring substances. In these cases, it is common practice to call those compounds contaminants which are known for their adverse effects such as acrylamide, whereas constituents which add to the food-specific flavor such as Maillard products formed during roasting, baking etc. are not termed contaminants. From a toxicological viewpoint this distinction is not always clear-cut. Important groups of chemical contaminants are metals such as mercury or lead, persistent organic pollutants such as polychlorinated biphenyls and related pollutants, which are regularly found in certain types of food originating from background levels of these compounds in our environment. Furthermore, natural toxins form microorganisms or plants, and compounds formed during thermal treatment of food are of major interest. In general, a scientific risk assessment has to be carried out for any known contaminant. This comprises an exposure analysis and a toxicological and epidemiological assessment. On these grounds, regulatory and/or technological measures can often improve the situation. Major conditions for a scientific risk assessment and a successful implementation of regulations are highly developed food quality control, food toxicology and nutritional epidemiology.

  13. Satellite Contamination and Materials Outgassing Knowledge base

    Minor, Jody L.; Kauffman, William J. (Technical Monitor)

    2001-01-01

    Satellite contamination continues to be a design problem that engineers must take into account when developing new satellites. To help with this issue, NASA's Space Environments and Effects (SEE) Program funded the development of the Satellite Contamination and Materials Outgassing Knowledge base. This engineering tool brings together in one location information about the outgassing properties of aerospace materials based upon ground-testing data, the effects of outgassing that has been observed during flight and measurements of the contamination environment by on-orbit instruments. The knowledge base contains information using the ASTM Standard E- 1559 and also consolidates data from missions using quartz-crystal microbalances (QCM's). The data contained in the knowledge base was shared with NASA by government agencies and industry in the US and international space agencies as well. The term 'knowledgebase' was used because so much information and capability was brought together in one comprehensive engineering design tool. It is the SEE Program's intent to continually add additional material contamination data as it becomes available - creating a dynamic tool whose value to the user is ever increasing. The SEE Program firmly believes that NASA, and ultimately the entire contamination user community, will greatly benefit from this new engineering tool and highly encourages the community to not only use the tool but add data to it as well.

    In the United States, approximately 100 patients develop fatal sepsis associated with platelet transfusions every year. Current culture methods take 24-48 hours to acquire results, which in turn decrease the shelf life of platelets. Many of the microorganisms that contaminate platelets can replicate easily at room temperature, which is the necessary storage temperature to keep platelets functional. Therefore, there is a need for in-situ quality control assessment of the platelet quality. For this purpose, a real time spectrophotometric technique has been developed. The Spectral Acquisition Processing Detection (SAPD) method, comprised of a UV-vis spectrophotometer and modeling algorithms, is a rapid method that can be performed prior to platelet transfusion to decrease the risk of bacterial infection to patients. The SAPD method has been used to determine changes in cell suspensions, based on size, shape, chemical composition and internal structure. Changes in these cell characteristics can in turn be used to determine microbial contamination, platelet aging and other physiologic changes. Detection limits of this method for platelet suspensions seeded with bacterial contaminants were identified to be less than 100 cfu/ml of sample. Bacterial counts below 1000 cfu/ml are not considered clinically significant. The SAPD method can provide real-time identification of bacterial contamination of platelets affording patients an increased level of safety without causing undue strain on laboratory budgets or personnel while increasing the time frame that platelets can be used by dramatically shortening contaminant detection time.

  15. Soils as a buffer of contaminants in catchments

    NASA Astrophysics Data System (ADS)

    Evrard, Olivier

    2014-05-01

    Human activities deliver large quantities of contaminants into the environment through atmospheric emissions or direct releases. As many of those contaminants are particle-reactive, they bind strongly to the finest particles or on their organic matter fraction once they deposit onto soils. Contaminants may subsequently migrate in depth of the soil depending on their physico-chemical characteristics. They may also be redistributed along hillslopes in association with particles during soil erosion events and may be subsequently supplied to rivers, preventing to meet the international environmental targets (e.g. in the framework of the EU Water Framework Directive). In regions where soil erosion rates are low to moderate, a large quantity of particle-reactive contaminants may accumulate in soils that constitute a reservoir of pollutants that may be delivered to rivers during decades or centuries. This session will focus on the specific role played by soils as a reservoir of contaminants at the catchment scale. A better understanding of this role and a quantification of the persistence of contaminants in this reservoir will provide crucial insights to guide the implementation of efficient mitigation measures. Contributions to this session may address any aspect of particle-borne contaminant transfer at the catchment scale, with an emphasis on the role played by soils in their storage and transfer. Field-based or modeling studies may focus either on specific pollutants or on a wider range of substances, e.g. metals, radionuclides, organic contaminants. Key themes may include: • Contaminant budget at the hillslope vs. the catchment scales; • Evaluation of the contribution of the regional vs. local contamination sources; • Evaluation of the contaminant removal from soils by degradation vs. soil erosion; • Quantifying the persistence of contaminants in soils; • Discrimination between the legacy and the contemporary supply of contaminants to soils.

  19. Podcasts--an emerging form of digital publishing.

    PubMed

    Johnson, L; Grayden, S

    2006-07-01

    Podcasting has recently emerged as an important information technology tool for health professionals and consumers around the world. Prestigious journals, international conferences, universities and government agencies among other entities are starting to publish digital informotion via audio and video podcasts. Podcosting is distinguished from other forms of digital audio-video content because it can be subscribed to (using Real Simple Syndication or RSS) and easily accessed from a personal computer. Further, it can be downloaded to a mobile device, such as an iPod where the user is able to listen to or watch it anywhere, anytime. Podcosting is used in new and evolving ways to publish information for healthcare education, patient care, professional continuing education, and in support of healthcare research. In addition to a description of what podcasting is, how podcasts are created, and how they are used, this paper addresses four critical issues that are emerging concerning podcasts. These issues are intellectual property and copyright, podcast preservation, podcast location, and podcast standards. As podcasting matures and new uses are discovered, we will see podcasting incorporated into our education, research and patient care publication paradigm.

  20. How To Promote Data Quality And Access? Publish It!

    2011-12-01

    Started during IPY 2007-2008, the Earth System Science Data journal (Copernicus) has now 'tested the waters' of earth system data publishing for approximately 2 years with some success. The journal has published more than 30 data sets, of remarkable breadth and variety, all under a Creative Commons Attribution license. Users can now find well-described, quality-controlled and freely accessible data on soils, permafrost, sediment transport, ice sheets, surface radiation, ocean-atmosphere fluxes, ocean chemistry, gravity fields, and combined radar and web cam observations of the Eyjafjallajökull eruption plume. Several of the data sets derive specifically from IPY or from polar regions, but a large portion, including a substantial special issue on ocean carbon, cover broad temporal and geographic domains; the contributors themselves come from leading science institutions around the world. ESSD has attracted the particular interest of international research teams, particularly those who, as in the case of ocean carbon data, have spent many years gathering, collating and calibrating global data sets under long-term named programs, but who lack within those programs the mechanisms to distribute those data sets widely outside their specialist teams and to ensure proper citation credit for those remarkable collaborative data processing efforts. An in-progress special issue on global ocean plankton function types, again representing years of international data collaboration, provides a further example of ESSD utility to large research programs. We anticipate an interesting test case of parallel special issues with companion science journals - data sets in ESSD to accompany science publications in a prominent research journal. We see the ESSD practices and products as useful steps to increase quality of and access to important data sets.

  7. Seven sins in publishing (but who's counting…)

    PubMed Central

    2016-01-01

    'Oh what a tangled web we weave, When first we practise to deceive.’ Sir Walter Scott (Marmion, 1808) Think of scientific misconduct in the UK and Malcolm Pearce – one of the most high-profile cases – comes immediately to mind. Malcolm Pearce was an assistant editor of the British Journal of Obstetrics and Gynaecology, and a senior lecturer at St George's Medical School, when two fraudulent papers were published in the journal. A whistleblower at the hospital was the catalyst for an investigation that led to Pearce being fired, found guilty of serious professional misconduct by the General Medical Council, and struck off.1 The professor of the department, Geoffrey Chamberlain, who was also President of the Royal College of Obstetricians and Gynaecologists and Editor of the journal, resigned from both positions as he was named as an author on one of the fraudulent papers. He reportedly did not know that his name was on the manuscript and, in his defence, it was not unusual at the time for Heads of Department to have ‘gift’ authorship on the department’s publications, despite not making any contribution. Regardless, both were disgraced. Scientific misconduct has many faces and its true prevalence is unknown, although many agree that it is increasing. Is it because researchers are committing more publication crimes, or are we just better at discovering them? In the race to find a home for articles, are authors getting lazy, sloppy and making more mistakes? In the era of online publications reaching wider audiences, mistakes are easier to detect and report, and beware if Clare Francis stumbles across such misdemeanours… Since 2010 an individual (or perhaps even a group) whose gender, identity and occupation are unknown, but who operate under the name ‘Clare Francis’, has upped the ante and flagged hundreds of suspected cases of potential fraud across the globe.

    Scientific software has become an indispensable commodity for the production, processing and analysis of empirical data but also for modelling and simulation of complex processes. Software has a significant influence on the quality of research results. For strengthening the recognition of the academic performance of scientific software development, for increasing its visibility and for promoting the reproducibility of research results, concepts for the publication of scientific software have to be developed, tested, evaluated, and then transferred into operations. For this, the publication and citability of scientific software have to fulfil scientific criteria by means of defined processes and the use of persistent identifiers, similar to data publications. The SciForge project is addressing these challenges. Based on interviews a blueprint for a scientific software publishing platform and a systematic implementation plan has been designed. In addition, the potential of journals, software repositories and persistent identifiers have been evaluated to improve the publication and dissemination of reusable software solutions. It is important that procedures for publishing software as well as methods and tools for software engineering are reflected in the architecture of the platform, in order to improve the quality of the software and the results of research. In addition, it is necessary to work continuously on improving specific conditions that promote the adoption and sustainable utilization of scientific software publications. Among others, this would include policies for the development and publication of scientific software in the institutions but also policies for establishing the necessary competencies and skills of scientists and IT personnel. To implement the concepts developed in SciForge a combined bottom-up / top-down approach is considered that will be implemented in parallel in different scientific domains, e.g. in earth sciences, climate research and

    Huchra, John

    Just in the last few years scientific publishing has moved rapidly away from the modes that served it well for over two centuries. As "digital natives" take over the field and rapid and open access comes to dominate the way we communicate, both scholarly journals and libraries need to adopt new business models to serve their communities. This is best done by identifying new "added value" such as databases, full text searching, full cross indexing while at the same time retaining the high quality of peer reviewed publication.

  13. Lead-210 contamination

    SciTech Connect

    Gray, P.

    1997-12-31

    Nearly all scrap dealers, smelters and other recyclers routinely monitor for radioactivity in shipments entering their facility. These sensitive radiation gate monitors easily detect radium-226 and most other radioactive nuclides. However, the type of detector normally used, sodium iodide scintillation crystals, will not detect the low energy gamma radiation emitted by lead-210 and its progeny. Since lead-210 is a common radioactive contaminant in certain industries, contaminated scrap metal from these industries may avoid detection at the recycler. Lead-210 is a decay product of radon-222 which is produced in small concentrations with natural gas. As the natural gas liquids, particularly ethane and propane, are separated from the natural gas, the radon concentrates in the ethane/propane fraction. The natural gas industry, particularly gas processing facilities and industries using ethane and propane as feed stocks can be significantly contaminated with the radon decay products, especially lead-210, bismuth-210 and polonium-210. Unless the scrap metal is decontaminated before sending to the recycler, the lead-210 contaminated scrap may be processed, resulting in some degree of radioactive contamination of the recycling facilities. Methods of detecting the low energy gamma radiation associated with lead-210 include the pancake G-M detector and the thin crystal-thin window scintillation detector.

  14. Surface Characterization and Contamination

    Workman, Gary L.

    1999-01-01

    Nondestructive characterization of surface contamination can play an extremely important role in improving quality in manufacturing processes. This area of interest led to the formation of a Surface Contamination Analysis Team (SCAT) at Marshall Space Flight Center, which is primarily concerned with critical bondlines and has provided the major focus for activities under this grant. In addition, determining minute levels of contamination on emerging aerospace systems fabricated from composites has also been an area of interest for which the methods being presented here can be used. Important considerations for the inspection methodologies are good sensitivity, large area coverage, robustness, portability and ease of use for normal production personnel. In parallel with the evaluation of detection methods, considerable effort has been made to developing good, uniform contamination films to use as calibration standards. This activity within itself has presented unique challenges. The development of NIR methods for detecting and identifying contaminants has been in progress for several years. Cooperative efforts between the University, NASA, and Thiokol Corporation has shown some useful results for implementation in both laboratory and on-line procedures.

    1991-10-01

    Long-term herbicide control along with a shotcrete cover was constructed at the Hanford Site in May 1991. The cover system allows for maintenance-free containment of contaminants by preventing wind and water transport of contaminants from the soil surface, preventing plant uptake of contaminants, and minimizing water infiltration through the soil column. The cover is composed of two parts: a commercial nonwoven geotextile material impregnated with trifluralin, and a >5-centimeter top cover of shotcrete containing polyethylene fibers. The herbicide-impregnated geotextile functions to prevent plant root growth into contaminated soil if any holes or cracks develop in the shotcrete layer. The herbicide component, trifluralin, is mixed into polymer nodules that degrade slowly over many years, thus releasing trifluralin slowly over time. The shotcrete topcover was sprayed using a sludge pump and air compressor to form a hard, impenetrable surface that prevents wind erosion and reduces water infiltration through the contaminated materials underneath. The benefits of the cover system are expected to last 20 to 30 years. 2 refs., 4 figs.

  17. Hand hygiene--comparison of international recommendations.

    PubMed

    Wendt, C

    2001-08-01

    The value of hand hygiene for the prevention of cross-infection was first observed in the middle of the 19th century. Since then, which procedure is the most suitable for hand hygiene has been repeatedly discussed and several different guidelines and recommendations have been published. The aim of this review is to compare different recommendations for hand hygiene regarding technique and indication. Medline, the internet and a personal library were searched to obtain as many written recommendations as possible. In addition, a small questionnaire was sent by e-mail to 20 international colleagues. As a result, written recommendations from 10 countries could be compared. Recommended methods of hand hygiene include handwashing (washing hands with plain soap), hygienic handwash (washing hands with medicated soap) and hygienic hand-rub (use of antiseptic rubs). In most countries handwashing and hygienic handwash are the methods of choice and only in central European countries is hygienic hand-rub the preferred technique. Situations in which performance of hand hygiene is recommended are comparable. However, no single indication is recommended in all guidelines. Hand hygiene is most often recommended before performing invasive procedures and after microbial contamination. Guidelines should be clear and easy to follow for them to become standard of care. Thus, guidelines are needed that do not leave to the health care worker a decision as to whether hand hygiene is indicated.

    Organic contaminants have become one of the most serious environmental problems, and the removal of organic contaminants (e.g., dyes, pesticides, and pharmaceuticals/drugs) and common industrial organic wastes (e.g., phenols and aromatic amines) from aqueous solutions is of special concern because they are recalcitrant and persistent in the environment. In recent years, carbon nanotubes (CNTs) have been gradually applied to the removal of organic contaminants from wastewater through adsorption processes. This paper reviews recent progress (145 studies published from 2010 to 2013) in the application of CNTs and their composites for the removal of toxic organic pollutants from contaminated water. The paper discusses removal efficiencies and adsorption mechanisms as well as thermodynamics and reaction kinetics. CNTs are predicted to have considerable prospects for wider application to wastewater treatment in the future.

    Mechanical redesign methods were used to minimize contamination damage of conventional fluid components and a contamination separator device was developed for long term reusable space vehicles. These were incorporated into an existing 50.8 mm poppet valve and tested for damage tolerance in a full size open loop flow system with gaseous and liquid nitrogen. Cyclic and steady flow conditions were tested with particles of 125 to 420 micrometers aluminum oxide dispersed in the test fluids. Nonflow life tests (100,000 cycles) were made with two valve configurations in gaseous hydrogen. The redesigned valve had an acceptable cycle life and improved tolerance to contamination damage when the primary sealing surfaces were coated with thin coatings of hard plastic (Teflon S and Kynar). Analytical studies and flow testing were completed of four different versions of the separator. overall separation efficiencies in the 55-90% range were measured with these non-optimum configurations.

  2. Towards an open science publishing platform

    PubMed Central

    Tracz, Vitek; Lawrence, Rebecca

    2016-01-01

    The way science and research is done is rapidly becoming more open and collaborative. The traditional way of publishing new findings in journals is becoming increasingly outdated and no longer serves the needs of much of science. Whilst preprints can bring significant benefits of removing delay and selection, they do not go far enough if simply implemented alongside the existing journal system. We propose that we need a new approach, an Open Science Platform, that takes the benefits of preprints but adds formal, invited, and transparent post-publication peer review. This bypasses the problems of the current journal system and, in doing so, moves the evaluation of research and researchers away from the journal-based Impact Factor and towards a fairer system of article-based qualitative and quantitative indicators. In the long term, it should be irrelevant where a researcher publishes their findings. What is important is that research is shared and made available without delay within a framework that encourages quality standards and requires all players in the research community to work as collaborators.

  3. Quantum game theory and open access publishing

    2007-08-01

    The digital revolution of the information age and in particular the sweeping changes of scientific communication brought about by computing and novel communication technology, potentiate global, high grade scientific information for free. The arXiv, for example, is the leading scientific communication platform, mainly for mathematics and physics, where everyone in the world has free access on. While in some scientific disciplines the open access way is successfully realized, other disciplines (e.g. humanities and social sciences) dwell on the traditional path, even though many scientists belonging to these communities approve the open access principle. In this paper we try to explain these different publication patterns by using a game theoretical approach. Based on the assumption, that the main goal of scientists is the maximization of their reputation, we model different possible game settings, namely a zero sum game, the prisoners’ dilemma case and a version of the stag hunt game, that show the dilemma of scientists belonging to “non-open access communities”. From an individual perspective, they have no incentive to deviate from the Nash equilibrium of traditional publishing. By extending the model using the quantum game theory approach it can be shown, that if the strength of entanglement exceeds a certain value, the scientists will overcome the dilemma and terminate to publish only traditionally in all three settings.

  4. Publishing perishing? Towards tomorrow's information architecture.

    2007-01-19

    Scientific articles are tailored to present information in human-readable aliquots. Although the Internet has revolutionized the way our society thinks about information, the traditional text-based framework of the scientific article remains largely unchanged. This format imposes sharp constraints upon the type and quantity of biological information published today. Academic journals alone cannot capture the findings of modern genome-scale inquiry. Like many other disciplines, molecular biology is a science of facts: information inherently suited to database storage. In the past decade, a proliferation of public and private databases has emerged to house genome sequence, protein structure information, functional genomics data and more; these digital repositories are now a vital component of scientific communication. The next challenge is to integrate this vast and ever-growing body of information with academic journals and other media. To truly integrate scientific information we must modernize academic publishing to exploit the power of the Internet. This means more than online access to articles, hyperlinked references and web-based supplemental data; it means making articles fully computer-readable with intelligent markup and Structured Digital Abstracts.Here, we examine the changing roles of scholarly journals and databases. We present our vision of the optimal information architecture for the biosciences, and close with tangible steps to improve our handling of scientific information today while paving the way for an expansive central index in the future.

  5. Assessing uncertainty in published risk estimates using ...

    EPA Pesticide Factsheets

    Introduction: The National Research Council recommended quantitative evaluation of uncertainty in effect estimates for risk assessment. This analysis considers uncertainty across model forms and model parameterizations with hexavalent chromium [Cr(VI)] and lung cancer mortality as an example. The objective is to characterize model uncertainty by evaluating estimates across published epidemiologic studies of the same cohort.Methods: This analysis was based on 5 studies analyzing a cohort of 2,357 workers employed from 1950-74 in a chromate production plant in Maryland. Cox and Poisson models were the only model forms considered by study authors to assess the effect of Cr(VI) on lung cancer mortality. All models adjusted for smoking and included a 5-year exposure lag, however other latency periods and model covariates such as age and race were considered. Published effect estimates were standardized to the same units and normalized by their variances to produce a standardized metric to compare variability within and between model forms. A total of 5 similarly parameterized analyses were considered across model form, and 16 analyses with alternative parameterizations were considered within model form (10 Cox; 6 Poisson). Results: Across Cox and Poisson model forms, adjusted cumulative exposure coefficients (betas) for 5 similar analyses ranged from 2.47 to 4.33 (mean=2.97, σ2=0.63). Within the 10 Cox models, coefficients ranged from 2.53 to 4.42 (mean=3.29, σ2=0.

    Do you write code for your research? Use astronomical software? Do you wish there were a better way of citing, sharing, archiving, or discovering software for astronomy research? You're not alone! In April 2015, AAS's publishing team joined other leaders in the astronomical software community in a meeting funded by the Sloan Foundation, with the purpose of discussing these issues and potential solutions. In attendance were representatives from academic astronomy, publishing, libraries, for-profit software sharing platforms, telescope facilities, and grantmaking institutions. The goal of the group was to establish “protocols, policies, and platforms for astronomical software citation, sharing, and archiving,” in the hopes of encouraging a set of normalized standards across the field. The AAS is now collaborating with leaders at GitHub to write grant proposals for a project to develop strategies for software discoverability and citation, in astronomy and beyond. If this topic interests you, you can find more details in this document released by the group after the meeting: http://astronomy-software-index.github.io/2015-workshop/ The group hopes to move this project forward with input and support from the broader community.

  7. Going digital: image preparation for biomedical publishing.

    PubMed

    Schenk, M P; Manning, R J; Paalman, M H

    1999-08-15

    Authors are more often being held responsible for readying their own data figures for digital publication by scanning them at the proper resolution and preparing them for presentation in both print and on-line journals. In this manner, the visuals can be printed at the highest quality the publisher can provide and be ready for rapid electronic distribution on the Internet. Therefore, authors must become knowledgeable in the visual preparation process in order to generate electronic images that will be as true a representation of the original image as possible. Perfecting this procedure can be a learning experience and often requires some experimentation. When accomplished, the author will have more control of exactly how the images will look before they are published. In addition to the scan resolution, the type of digital scanner and software applications used are very important, and instruction manuals should be followed closely so as to understand the full potential of the digitizing equipment.

  8. Cooperation and coauthorship in scientific publishing

    2015-01-01

    Research collaboration occurs more frequently today than in the past. As a consequence, cooperation and competition are crucial determinants of academic success. In multiauthored publications, not all authors contribute evenly. Hence, some authors end up with less time or resources to work on parallel projects, decreasing their number of publications. Although detailed information on the contribution of each author in multiauthored publications is generally not available, the order of authors often discloses information on differential contributions. Here we analyze the full data set of Physical Review journals to show that, along with the increasingly number of multiauthored publications, first authors incur costs and last authors are bestowed benefits in terms of number of publications. In other words, authors publishing more often as first authors have fewer publications in the short-term than authors publishing more often as last authors. Using a simplified network representation where direct links represent the costly action of first authors towards last authors, we analyze the evolution of cooperation in multiauthored publications.

While employing seemingly simple process technologies, sizing the active contamination control equipment must employ a reliable design basis for the trace chemical load in the cabin atmosphere. A simplified design basis that draws on experience gained from the International Space Station program is presented. The trace chemical contamination control design load refines generation source magnitudes and includes key chemical functional groups representing both engineering and toxicology challenges.

    1998-01-01

    A contamination sample collection device has a wooden dowel with a cotton swab at one end, the cotton being covered by a nylon cloth and the wooden dowel being encapsulated by plastic tubing which is heat shrunk onto the dowel and onto a portion of the cotton swab to secure the cotton in place. Another plastic tube is heat shrunk onto the plastic that encapsulates the dowel and a portion of the nylon cloth to secure the nylon cloth in place. The device may thereafter be covered with aluminum foil protector. The device may be used for obtaining samples of contamination in clean room environments.

    The external induced environment generated by space station activity, or more specifically by gases, particles, and light background is discussed. These contaminant species must be controlled if sensitive systems, such as solar energy collectors or science experiments exposed to the external environment are to function properly. The requirements generally set limits on the level of gas species, matter deposited on surfaces and light background levels over various spectral regions. They also address environment monitoring and contamination controls during manufacturing. Limits on effluent release and system leakages are in turn derived from these requirements.

    1992-07-01

    Problems on groundwater contamination in Japan are briefly summarized in this paper. Although normal physical conditions in Japan restrict the possibilities of groundwater contamination, human activities are threatening groundwater resources. A survey by the Environment Agency of Japan showed nationwide spreading of organic substances, such as trichloroethylene as well as nitrogen compounds. Synthetic detergents have also been detected even in rural areas and in deep confined aquifers, although their concentrations are not as high. Public awareness of agrichemical or pesticides abuse, especially from golf courses, is apparent. Other problems such as nitrate-nitrogen, leachate from landfills, and the leaking of underground storage tanks are also discussed.

    A Model has been developed capable of calculating the electrostatic return of spacecraft-emitted molecules that are ionized and attracted back to the spacecraft by the spacecraft electric potential on its surfaces. The return of ionized contaminant molecules to charged spacecraft surfaces is very important to all altitudes. It is especially important at geosynchronous and interplanetary environments, since it may be the only mechanism by which contaminants can degrade a surface. This model is applicable to all altitudes and spacecraft geometries. In addition to results of the model will be completed to cover a wide range of potential space systems.

    1988-01-01

    The in-situ optical surface measurement system is a facility designed to study the deleterious effects of particulate materials on the surface reflectivities of optical materials in the vacuum ultraviolet (VUV). This arrangement is designed to simulate the on-orbit effects of contamination and degradation of optical surfaces. This simulation is accomplished through the use of non-coherent VUV sources illuminating optical surfaces located in a high vacuum chamber. Several sources of contamination are employed. The reflectivity is measured both at the specular reflection as well as at two scattered positions, forward and reverse. The system components are described and an operating procedure is given.

    2015-08-01

    Most researchers today are bombarded with spam email solicitations from questionable scholarly publishers. These emails solicit article manuscripts, editorial board service, and even ad hoc peer reviews. These "predatory" publishers exploit the scholarly publishing process, patterning themselves after legitimate scholarly publishers yet performing little or no peer review and quickly accepting submitted manuscripts and collecting fees from submitting authors. These counterfeit publishers and journals have published much junk science — especially in the field of cosmology — threatening the integrity of the academic record. This presentation examines the current state of predatory publishing and related scams such as fake impact factors and advises researchers how to navigate scholarly publishing to best avoid predatory publishers and other scholarly publishing-related perils.

    Proposed rules by the Bureau of Land Management (BLM) and the US Geological Survey (USGS) are designed to streamline the existing federal coal leasing rules and ultimately accelerate the offering of publicly-owned coal lands, according to an announcement by Interior Secretary James Watt. The rules were published in the December 16, 1981 federal Register. The BLM and the USGS proposed rules (which appear in the Code of Federal Regulations, Group 3400 of Title 43 and Part 211 of Title 30, respectively) are coordinated and cross-referenced to serve as a total revision of the Federal coal leasing program. The proposed rules maintain the existing structure of the Federal coal management program, but make several important modifications that strengthen the program and add needed flexibility.

  6. Answer or Publish - Energizing Online Democracy

    NASA Astrophysics Data System (ADS)

    Antal, Miklós; Mikecz, Dániel

    Enhanced communication between citizens and decision makers furthering participation in public decision making is essential to ease today's democratic deficit. However, it is difficult to sort out the most important public inputs from a large number of comments and questions. We propose an online solution to the selection problem by utilizing the general publicity of the internet. In the envisioned practice, decision makers are obliged either to answer citizens' questions or initiatives or to publish the letter received on a publicly accessible web page. The list of unaddressed questions would mean a motivation to consider public inputs without putting unnecessary burdens on decision makers - due to the reliance on the public, their workload would converge to the societal optimum. The proposed method is analyzed in the course of the existing Hungarian e-practices. The idea is found valuable as a restriction for representatives and a relief for some other officials.

  7. How to Write Articles that Get Published

    PubMed Central

    2014-01-01

    Publications are essential for sharing knowledge, and career advancement. Writing a research paper is a challenge. Most graduate programmes in medicine do not offer hands-on training in writing and publishing in scientific journals. Beginners find the art and science of scientific writing a daunting task. ‘How to write a scientific paper?, Is there a sure way to successful publication ?’ are the frequently asked questions. This paper aims to answer these questions and guide a beginner through the process of planning, writing, and correction of manuscripts that attract the readers and satisfies the peer reviewers. A well-structured paper in lucid and correct language that is easy to read and edit, and strictly follows the instruction to the authors from the editors finds favour from the readers and avoids outright rejection. Making right choice of journal is a decision critical to acceptance. Perseverance through the peer review process is the road to successful publication. PMID:25386508

  8. Information revolution: William Chambers, the publishing pioneer.

    2006-12-01

    With the arrival of steam power and new machinery in the 19th century, the production of printed media was transformed for the first time since the emergence of the printing press more than 300 years earlier. Yet until the 1850s, most publishers remained content with traditional methods, which enabled them to make profits from a small but affluent circle of readers. This article (part of the Science in the Industrial Revolution series) will show how William Chambers (1800-1883) was one of the first to make full use of the new technologies. He was driven by a determination to reach readers of all social classes, to produce a genuinely cheap instructive publication and to overcome the challenges of reaching a national market from his base in Edinburgh.

    2006-12-01

    2006 has proved to be a very successful year for Inverse Problems. After an increase for the fourth successive year, we achieved our highest impact factor to date, 1.541 (Source: 2005 ISI® Journal Citation Report), and the Editorial Board is keen to build on this success by continuing to improve the service we offer to our readers and authors. The Board has observed that Inverse Problems receives very few Letters to the Editor submissions, and that moreover those that we do receive rarely conform to the requirements for Letters to the Editor set out in the journal's editorial policy. The Board has therefore decided to merge the current Letters to the Editor section into our regular Papers section, which will now accommodate all research articles that meet the journal's high quality standards. Any submissions that would previously have been Letters to the Editor are still very welcome as Papers, and can be submitted by e-mail to ip@iop.org or online using our online submissions form at authors.iop.org/submit. Inverse Problems' processing times are already among the fastest in the field—on average, authors receive our decision on their paper in less than three months. Thanks to our easy-to-use online refereeing system, publishing a Paper is now just as fast as publishing a Letter to the Editor, and we are striving to ensure that the journal's high standards are applied consistently to all our Papers, maintaining Inverse Problems' position as the leading journal in the field. Our highly acclaimed Topical Review section will also continue and grow; providing timely insights into the development of all topical fields within Inverse Problems. We have many exciting Topical Reviews currently in preparation for 2007 and will continue to commission articles at the cutting edge of research. We look forward to receiving your contributions and to continuing to provide the best publication service available.

    Mobility traces of people and vehicles have been collected and published to assist the design and evaluation of mobile networks, such as large-scale urban sensing networks. Although the published traces are often made anonymous in that the true identities of nodes are replaced by random identifiers, the privacy concern remains. This is because in real life, nodes are open to observations in public spaces, or they may voluntarily or inadvertently disclose partial knowledge of their whereabouts. Thus, snapshots of nodes’ location information can be learned by interested third parties, e.g., directly through chance/engineered meetings between the nodes and their observers,more » or indirectly through casual conversations or other information sources about people. In this paper, we investigate how an adversary, when equipped with a small amount of the snapshot information termed as side information, can infer an extended view of the whereabouts of a victim node appearing in an anonymous trace. Our results quantify the loss of victim nodes’ privacy as a function of the nodal mobility, the inference strategies of adversaries, and any noise that may appear in the trace or the side information. Generally, our results indicate that the privacy concern is significant in that a relatively small amount of side information is sufficient for the adversary to infer the true identity (either uniquely or with high probability) of a victim in a set of anonymous traces. For instance, an adversary is able to identify the trace of 30%-50% of the victims when she has collected 10 pieces of side information about a victim.« less

  18. Analysis of the Holart Report project: recording and publishing sales data for fine art holograms

    NASA Astrophysics Data System (ADS)

    Zellerbach, Gary A.

    1995-02-01

    At Lake Forest College's Fourth International Symposium on Display Holography (July 1991), the author first formulated an idea to promote fine art holography by recording and publishing sale prices for art holograms. The idea was mentioned to several prominent artists in attendance, and the response was enthusiastic. The author formed a new company to publish the world's first journal of international art hologram sales, the Holart Report. Holart Report published four quarterly issues, beginning in May 1992. During that time, the publisher created a significant database of hologram art sales and reported tens of thousands of dollars in holographic art transactions. In February 1993 the author's new job obligations and a general lack of support for the project forced him to suspend publication of Holart Report. This paper attempts to answer serious questions surrounding the experience. What problems were encountered? What benefits, if any, did Holart provide during its short lifetime? Why were many in the holographic art community reluctant to support the project? In retrospect, what should have been done differently to ensure greater success? Lastly, the author states his belief that the idea remains feasible and valuable. The database is intact and the publishing template established. The lessons learned can be used to produce a much improved new version of Holart Report or a similar publication.

  19. Hazard identification for contaminants.

    PubMed

    Iscan, Mümtaz

    2004-12-15

    In recent years, the recognition of generation of large quantities of toxicants and their by-products due to the industrial and/or cultural activities and transport and their persistence in the environment and biological activities brings out the necessity and importance of their assessment of risk they pose to the ecosystems (e.g. aquatic environment-coastal waters, rivers, lakes and ground water). Indeed, understanding the impacts of contaminants on the environment, including the organisms which live in it, is rather complicated. Nevertheless, the need for protection of the scarce natural resources in the environment and wiser use of them brings the necessity and importance of focusing more attention to the issue. Accordingly the process of ecological risk assessment (ERA) has evolved rapidly since the Environmental Protection Agency (EPA) issued a framework for ecological risk assessment in 1992. The ecological risk assessment involves three stages in a continuous process: (1) problem formulation (problem identification-hazard identification), (2) the analysis of exposure and effects and (3) risk characterisation. Risk management follows the risk characterisation. Of these stages, problem identification is the most critical one which establishes the direction and scope of the ecological risk assessment. The stage involves identifying the actual environmental value(s) to be protected (assessment endpoints) and selecting ways in which these can be measured and evaluated (measurement endpoints). The accuracy of the risk estimation is largely based on the availability of the key information about the contaminant characteristics, ecosystem at risk and ecological effects and the less uncertainty associated with them. The key information required during this phase of the risk assessment process are as follows: (a) potential/actual contaminant of concern, (b) source of contaminant; current and historic use, (c) mode of action of the contaminant, (d) contaminant

    There are two objectives of this report, ''Subsurface Contamination Control''. The first is to provide a technical basis for recommending limiting radioactive contamination levels (LRCL) on the external surfaces of waste packages (WP) for acceptance into the subsurface repository. The second is to provide an evaluation of the magnitude of potential releases from a defective WP and the detectability of the released contents. The technical basis for deriving LRCL has been established in ''Retrieval Equipment and Strategy for Wp on Pallet'' (CRWMS M and O 2000g, 6.3.1). This report updates the derivation by incorporating the latest design information of the subsurface repository for site recommendation. The derived LRCL on the external surface of WPs, therefore, supercede that described in CRWMS M and O 2000g. The derived LRCL represent the average concentrations of contamination on the external surfaces of each WP that must not be exceeded before the WP is to be transported to the subsurface facility for emplacement. The evaluation of potential releases is necessary to control the potential contamination of the subsurface repository and to detect prematurely failed WPs. The detection of failed WPs is required in order to provide reasonable assurance that the integrity of each WP is intact prior to MGR closure. An emplaced WP may become breached due to manufacturing defects or improper weld combined with failure to detect the defect, by corrosion, or by mechanical penetration due to accidents or rockfall conditions. The breached WP may release its gaseous and volatile radionuclide content to the subsurface environment and result in contaminating the subsurface facility. The scope of this analysis is limited to radioactive contaminants resulting from breached WPs during the preclosure period of the subsurface repository.

    Some types of reused dental equipment, especially handpieces and their attachments for drilling and cleaning teeth, might be responsible for cross-contamination if patient material were to lodge temporarily in difficult-to-disinfect internal mechanisms. This possibility is worrisome with respect to transmission of hepatitis B and human immunodeficiency viruses (HBV, HIV). Previous cross-contamination studies have relied on laboratory experiments with bacteria or dye tracers. To assess possible risk more thoroughly, we tested 30 new prophylaxis angles and 12 new high-speed handpieces to see whether they would take up and expel contaminants in laboratory and clinical trials. In treatments of three patients, including two infected with HIV, human-specific DNA (beta-globin, HLA DQ alpha) and HIV proviral DNA were detected inside or coming back from the devices. Similarly, when handpieces were operated in contact with blood pooled from HBV-infected patients, HBV DNA was detected in samples taken from inside the equipment and from their attached air/water hoses. When we used bacteriophage phi X174 as a model virus in laboratory tests, many infective viral particles were recovered from internal mechanisms of handpieces, their connecting air/water hoses, and from water spray expelled when the equipment was reused. We recommend that reused high-speed, air-driven handpieces and prophylaxis angles should be cleaned and heat-treated between patients. Further studies are needed to determine ways of eliminating the risks associated with exhaust hoses and air/water input lines.

    Radioactive contamination from the Chernobyl meltdown spread over 40% of Europe (including Austria, Finland, Sweden, Norway, Switzerland, Romania, Great Britain, Germany, Italy, France, Greece, Iceland, Slovenia) and wide territories in Asia (including Turkey, Georgia, Armenia, Emirates, China), northern Africa, and North America. Nearly 400 million people resided in territories that were contaminated with radioactivity at a level higher than 4 kBq/m(2) (0.11 Ci/km(2)) from April to July 1986. Nearly 5 million people (including, more than 1 million children) still live with dangerous levels of radioactive contamination in Belarus, Ukraine, and European Russia. Claims that the Chernobyl radioactive fallout adds "only 2%" to the global radioactive background overshadows the fact that many affected territories had previously dangerously high levels of radiation. Even if the current level is low, there was high irradiation in the first days and weeks after the Chernobyl catastrophe. There is no reasonable explanation for the fact that the International Atomic Energy Agency and the World Health Organization (Chernobyl Forum, 2005) have completely neglected the consequences of radioactive contamination in other countries, which received more than 50% of the Chernobyl radionuclides, and addressed concerns only in Belarus, Ukraine, and European Russia.

    Let's face it: wherever we go, we will inevitably carry along the little critters that live in and on us. Conventional wisdom has long held that it's unlikely those critters could survive the space environment, but in 2007 microscopic animals called Tardigrades survived exposure to space and in 2008 Cyanobacteria lived for 548 days outside the International Space Station (ISS). But what about the organisms we might reasonably expect a crewed spacecraft to leak or vent? Do we even know what they are? How long might our tiny hitch-hikers survive in close proximity to a warm spacecraft that periodically leaks/vents water or oxygen-and how might they mutate with long-duration exposure? Unlike the Mars rovers that we cleaned once and sent on their way, crew members will provide a constantly regenerating contaminant source. Are we prepared to certify that we can meet forward contamination protocols as we search for life at new destinations? This project has four technical objectives: 1. TEST: Develop a test plan to leverage existing equipment (i.e. ISS) to characterize the kinds of organisms we can reasonably expect pressurized, crewed volumes to vent or leak overboard; 2. ANALYSIS: Develop an analysis plan to study those organisms in relevant destination environments, including spacecraft-induced conditions; 3. MODEL: Develop a modeling plan to model organism transport mechanisms in relevant destination environments; 4. SHARE: Develop a plan to disseminate findings and integrate recommendations into exploration requirements & ops. In short, we propose a system engineering approach to roadmap the necessary experiments, analysis, and modeling up front--rather than try to knit together disparate chunks of data into a sensible conclusion after the fact.

  6. Characterize Human Forward Contamination Project

    Let's face it: wherever we go, we will inevitably carry along the little critters that live in and on us. Conventional wisdom has long held that it's unlikely those critters could survive the space environment, but in 2007 microscopic animals called Tardigrades survived exposure to space and in 2008 Cyanobacteria lived for 548 days outside the International Space Station (ISS). But what about the organisms we might reasonably expect a crewed spacecraft to leak or vent? Do we even know what they are? How long might our tiny hitch-hikers survive in close proximity to a warm spacecraft that periodically leaks/vents water or oxygen-and how might they mutate with long-duration exposure? Unlike the Mars rovers that we cleaned once and sent on their way, crew members will provide a constantly regenerating contaminant source. Are we prepared to certify that we can meet forward contamination protocols as we search for life at new destinations? This project has four technical objectives: 1. TEST: Develop a test plan to leverage existing equipment (i.e. ISS) to characterize the kinds of organisms we can reasonably expect pressurized, crewed volumes to vent or leak overboard; as part of testing, we'll need to develop an Extravehicular Activity (EVA)-compatible tool that can withstand the pressure and temperature extremes of space, as well as collect, separate, and store multiple samples; 2. ANALYSIS: Develop an analysis plan to study those organisms in relevant destination environments, including spacecraft-induced conditions; 3. MODEL: Develop a modeling plan to model organism transport mechanisms in relevant destination environments; 4. SHARE: Develop a plan to disseminate findings and integrate recommendations into exploration requirements & ops. In short, we propose a system engineering approach to roadmap the necessary experiments, analysis, and modeling up front--rather than try to knit together disparate chunks of data into a sensible conclusion after the fact.

    This study concerns the possible use of boundary layer (BL) approach for the analysis and evaluation of contaminant transport in groundwater due to contaminant penetration into the groundwater aquifer through a site of limited size. The contaminant penetration may occur through either the upper (surface) or lower (bedrock) boundary of the aquifer. Two general cases of contaminant penetration mechanisms are considered: (1) the contaminant is transferred through an interface between a contaminating and freshwater fluid phases, and (2) the contaminant arrives at groundwater by leakage and percolation. For the purpose of BL evaluation the contaminant plume is divided into three different sections: (1) the penetration section, (2) the extension-expansion section, and (3) the spearhead section. In each section a different BL method approach yields simple analytical expressions for the description of the contaminant plume migration and contaminant transport. Previous studies of the BL method can be directly applied to the evaluation of contaminant transport at the contaminant penetration section. The present study extends those studies and concerns the contaminant transport in the two other sections, which are located downstream of the penetration section. This study shows that the contaminant concentration profiles in sections 2 and 3 incorporate two BLs: (1) an inner BL adjacent to the aquifer bottom or surface boundary, and (2) an outer BL, which develops above or below the inner one. The method developed in the present study has been applied to practical issues concerning salinity penetration into groundwater in south central Kansas.

    As natural resources become increasingly limited, the value of restoring contaminated sites, both terrestrial and aquatic, becomes increasingly apparent. Traditionally, goals for remediation have been set before any consideration of goals for ecological restoration. The goals for remediation have focused on removing or limiting contamination whereas restoration goals have targeted the ultimate end use. Here, we present a framework for developing a comprehensive set of achievable goals for ecological restoration of contaminated sites to be used in concert with determining goals for remediation. This framework was developed during a Society of Environmental Toxicology and Chemistry (SETAC) and Society of Ecological Restoration (SER) cosponsored workshop that brought together experts from multiple countries. Although most members were from North America, this framework is designed for use internationally. We discuss the integration of establishing goals for both contaminant remediation and overall restoration, and the need to include both the restoration of ecological and socio-cultural-economic value in the context of contaminated sites. Although recognizing that in some countries there may be regulatory issues associated with contaminants and clean up, landscape setting and social drivers can inform the restoration goals. We provide a decision tree support tool to guide the establishment of restoration goals for contaminated ecosystems. The overall intent of this decision tree is to provide a framework for goal setting and to identify outcomes achievable given the contamination present at a site.

    Sediment physicochemical characteristics, benthic community structure, and toxicity were measured at reference and contaminated intertidal mudflats around the North Island of New Zealand. Chronic whole-sediment toxicity tests were conducted with the estuarine amphipod, Chaetocorophium lucasi and the marine bivalve, Macomona lilana, and pore-water toxicity tests were conducted with embryos of the echinoid, Fellaster zelandiae. Although concentrations of organic chemicals and heavy metals were up to several orders of magnitude higher at the sites considered to be contaminated, levels of contamination were relatively low compared to internationally based sediment quality guidelines. Although no pronounced difference was found in benthic community structure between reference and contaminated sites, multivariate analysis indicated that natural sediment characteristics and factors related to contamination may have been affecting community structure. Although benthic effects caused by present levels of contamination are not yet dramatic, subtle changes in community structure related to pollution may be occurring. The two whole-sediment and the pore-water toxicity tests presented different response patterns. Growth of C. lucasi and M. liliana was a less sensitive endpoint than survival. None of the three toxicity tests responded more strongly to the contaminated than to the reference sites, that is, neither natural-sediment and pore-water characteristics nor unmeasured contaminants affected the test organisms. It is possible that sediment collection and handling may have induced chemical changes, confounding interpretation of toxicity tests.

    Chemical contamination has impaired ecosystems, reducing biodiversity and the provisioning of functions and services. This has spurred a movement to restore contaminated ecosystems and develop and implement national and international regulations that require it. Nevertheless, ecological restoration remains a young and rapidly growing discipline and its intersection with toxicology is even more nascent and underdeveloped. Consequently, we provide guidance to scientists and practitioners on when, where, and how to restore contaminated ecosystems. Although restoration has many benefits, it also can be expensive, and in many cases systems can recover without human intervention. Hence, the first question we address is: “When should we restore contaminated ecosystems?” Second, we provide suggestions on what to restore—biodiversity, functions, services, all 3, or something else—and where to restore given expected changes to habitats driven by global climate change. Finally, we provide guidance on how to restore contaminated ecosystems. To do this, we analyze critical aspects of the literature dealing with the ecology of restoring contaminated ecosystems. Additionally, we review approaches for translating the science of restoration to on-the-ground actions, which includes discussions of market incentives and the finances of restoration, stakeholder outreach and governance models for ecosystem restoration, and working with contractors to implement restoration plans. By explicitly considering the mechanisms and strategies that maximize the success of the restoration of contaminated sites, we hope that our synthesis serves to increase and improve collaborations between restoration ecologists and ecotoxicologists and set a roadmap for the restoration of contaminated ecosystems.

    Although subway ventilation has been studied extensively, very little has been published on dispersion of contaminants in the subway environment. This paper presents a model that predicts dispersion of contaminants in a complex subway system. It accounts for the combined transient effects of train motion, station airflows, train car air exchange rates, and source release properties. Results are presented for a range of typical subway scenarios. The effects of train piston action and train car air exchange are discussed. The model could also be applied to analyze the environmental impact of hazardous materials releases such as chemical and biological agents.

    Student learning in science is improved by authentic personal experience of research projects and the publication of findings. Graduate students do this, but it is uncommon to find student research and publishing in high school science programs. We describe here the Student Research and Publishing Program (SRPP) established at International School Bangkok (ISB). We then discuss the effects of the SRPP on student attitudes and skills. Finally, we present a model detailing the criteria and processes recommended for the implementation of an SRPP in other high schools.

    Pathogen-Host interaction data is core to our understanding of disease processes and their molecular/genetic bases. Facile access to such core data is particularly important for the plant sciences, where individual genetic and phenotypic observations have the added complexity of being dispersed over a wide diversity of plant species vs. the relatively fewer host species of interest to biomedical researchers. Recently, an international initiative interested in scholarly data publishing proposed that all scientific data should be "FAIR"-Findable, Accessible, Interoperable, and Reusable. In this work, we describe the process of migrating a database of notable relevance to the plant sciences-the Pathogen-Host Interaction Database (PHI-base)-to a form that conforms to each of the FAIR Principles. We discuss the technical and architectural decisions, and the migration pathway, including observations of the difficulty and/or fidelity of each step. We examine how multiple FAIR principles can be addressed simultaneously through careful design decisions, including making data FAIR for both humans and machines with minimal duplication of effort. We note how FAIR data publishing involves more than data reformatting, requiring features beyond those exhibited by most life science Semantic Web or Linked Data resources. We explore the value-added by completing this FAIR data transformation, and then test the result through integrative questions that could not easily be asked over traditional Web-based data resources. Finally, we demonstrate the utility of providing explicit and reliable access to provenance information, which we argue enhances citation rates by encouraging and facilitating transparent scholarly reuse of these valuable data holdings.
