    Several fiery rail accidents in 2013-2015 in the U.S. and Canada carrying crude oil produced from the Bakken region of North Dakota have raised questions at many levels on the safety of transporting this, and other types of crude oil, by rail. Sandia National Laboratories was commissioned by the U.S. Department of Energy to investigate the material properties of crude oils, and in particular the so-called "tight oils" like Bakken that comprise the majority of crude oil rail shipments in the U.S. at the current time. The current report is a literature survey of public sources of information on crude oil properties that have some bearing on the likelihood or severity of combustion events that may occur around spills associated with rail transport. The report also contains background information including a review of the notional "tight oil" field operating environment, as well a basic description of crude oils and potential combustion events in rail transport.

    This report reviews mild gasification processes with respect to processing conditions and configurations. Special emphasis was placed on processes which could be commercialized within five years. Detailed market information was provided by J.E. Sinor concerning markets and economic considerations of the various processing steps. Processing areas studied include coal cleaning; mild gasification; and upgrading of the char, condensables, and hydrocarbon gases. Pros and cons in the different processing areas as well as ''gaps'' in pertinent data were identified and integrated into a detailed process development program. The report begins with a summary of the market assessment and an evaluation of the co-product. The impacts of feed materials and operating parameters--including coal rank, heating rate, pressure, agglomeration, temperature, and feed gas composition--on the co- products and processes were evaluated through a literature survey. Recommendations were made as to the preferred product specifications and operating parameters for a commercial plant. A literature review of mild gasification processes was conducted and evaluated with regard to product specification and operating parameters. Two candidate processes were chosen and discussed in detail with respect to scale-up feasibility. Recommendations were then made to process development needs to further consideration of the two processes. 129 refs., 33 figs., 16 tabs.

  19. Safety signal detection: the relevance of literature review.

    Science.gov (United States)

    Pontes, Helena; Clément, Mallorie; Rollason, Victoria

    2014-07-01

    Adverse drug reactions (ADRs) represent an important risk for patients and have a significant economic impact on health systems. ADRs are the fifth most common cause of hospital death, with a burden estimated at 197,000 deaths per year in the EU. This has a societal cost of 79 billion per year. Because of this strong impact in public health, regulatory authorities (RAs) worldwide are implementing new pharmacovigilance legislation to promote and protect public health by reducing the burden of ADRs through the detection of safety signals. Although, traditionally, signal detection activities have mainly been performed based on spontaneous reporting from healthcare professionals and national health RAs, the new pharmacovigilance legislation underlines the relevance of other sources of information (such as scientific literature) for the evaluation of the benefit-risk balance of a certain product. This review aims to highlight the relevance of periodic scientific literature screening in the safety signal detection process. The authors present four practical examples where a safety signal that was detected from a literature report had an impact on the lifecycle of a drug. In addition, based on practical experience of the screening of medical and scientific literature for safety purposes, this article analyses the requirements of the new pharmacovigilance guidelines on literature screening and highlights the need for the implementation of a literature review procedure and the main challenges encountered when performing literature screening for safety aspects.

  20. THE LEVEL OF KNOWLEDGE IN THE VALUE RELEVANCE LITERATURE

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available In the last decades, numerous studies have covered the relationship between stock price or stock return and financial information. These studies represent the "value-relevance" literature. Knowledge of this area of interest, through literature and the main ideas, yields scientific progress. The aim of the study is to achieve a qualitative and a quantitative analysis regarding the level of knowledge in the value relevance literature, in an international context. To achieve this aim, a number of 53 scientific articles published between 2001 and 2013 were selected, from the first two journals related to the number of citations in the rankings compiled by Google Scholar, Accounting and Taxation category. Qualitative analysis and quantitative analysis (factorial analysis of multiple correspondences as statistical method were used. The results reflect the importance of existing problems in the financial markets. The studies are focused on solving these problems, to support the investors.

  7. NITRATE DESTRUCTION LITERATURE SURVEY AND EVALUATION CRITERIA

    Energy Technology Data Exchange (ETDEWEB)

    Steimke, J.

    2011-02-01

    literature survey of technologies to perform the nitrate to hydroxide conversion, selection of the most promising technologies, preparation of a flowsheet and design of a system. The most promising technologies are electrochemical reduction of nitrates and chemical reduction with hydrogen or ammonia. The primary reviewed technologies are listed and they aredescribed in more detail later in the report: (1) Electrochemical destruction; (2) Chemical reduction with agents such as ammonia, hydrazine or hydrogen; (3) Hydrothermal reduction process; and (4) Calcination. Only three of the technologies on the list have been demonstrated to generate usable amounts of caustic; electrochemical reduction and chemical reduction with ammonia, hydrazine or hydrogen and hydrothermal reduction. Chemical reduction with an organic reactant such as formic acid generates carbon dioxide which reacts with caustic and is thus counterproductive. Treatment of nitrate with aluminum or other active metals generates a solid product. High temperature calcination has the potential to generate sodium oxide which may be hydrated to sodium hydroxide, but this is unproven. The following criteria were developed to evaluate the most suitable option. The numbers in brackets after the criteria are relative weighting factors to account for importance: (1) Personnel exposure to radiation for installation, routine operation and maintenance; (2) Non-radioactive safety issues; (3) Whether the technology generates caustic and how many moles of caustic are generated per mole of nitrate plus nitrite decomposed; (4) Whether the technology can handle nitrate and nitrite at the concentrations encountered in waste; (5) Maturity of technology; (6) Estimated annual cost of operation (labor, depreciation, materials, utilities); (7) Capital cost; (8) Selectivity to nitrogen as decomposition product (other products are flammable and/or toxic); (9) Impact of introduced species; (10) Selectivity for destruction of nitrate vs

    Goolsby, Tiffany A; Jakeman, Bernadette; Gaynes, Robert P

    2017-09-05

    The objective of this paper was to review and evaluate the literature on metronidazole-associated peripheral neuropathy and determine the relevance in clinical practice. MEDLINE/PubMed, EBSCO, and Google Scholar were searched through February 2017 using the search terms metronidazole and peripheral neuropathy, or polyneuropathy, or paresthesia, or neurotoxicity. Relevant case reports, retrospective studies, surveys, and review articles were included. Bibliographies of all relevant articles were reviewed for additional sources. Overall, metronidazole is generally well tolerated but serious neurotoxicity, including peripheral neuropathy, has been reported. The overall incidence of peripheral neuropathy associated with metronidazole is unknown. Our review found 36 case reports (40 unique patients) of metronidazole-associated peripheral neuropathy with the majority of cases receiving >42 total grams (>4 weeks) of therapy (31 out of 40). In addition, we reviewed 13 clinical studies and found varying rates of peripheral neuropathy from 0-50%. Within these clinical studies, we found a higher incidence of peripheral neuropathy in patients receiving >42 total grams (>4 weeks) of metronidazole compared to those patients receiving ≤ 42 total grams (17.9% vs 1.7%). Nearly all patients had complete resolution of symptoms. In conclusion, peripheral neuropathy is exceedingly rare in patients who receive ≤ 42 total grams of metronidazole. Patients who receive larger total doses may be at higher risk of peripheral neuropathy but most patients have resolution of symptoms after discontinuing therapy. Antimicrobial stewardship programs may consider use of antibiotic combinations that include metronidazole over broad-spectrum alternatives when treating with ≤42 grams of the drug (≤4 weeks).

    Quantifying scientific relevancy is of increasing importance to NASA and the research community. Scientific relevancy may be defined by mapping the impacts of a particular NASA mission, instrument, and/or retrieved variables to disciplines such as climate predictions, natural hazards detection and mitigation processes, education, and scientific discoveries. Related to relevancy, is the ability to expose data with similar attributes. This in turn depends upon the ability for us to extract latent, implicit document features from scientific data and resources and make them explicit, accessible and useable for search activities amongst others. This paper presents MemexGATE; a server side application, command line interface and computing environment for running large scale metadata extraction, general architecture text engineering, document classification and indexing tasks over document resources such as social media streams, scientific literature archives, legal documentation, etc. This work builds on existing experiences using MemexGATE (funded, developed and validated through the DARPA Memex Progrjam PI Mattmann) for extracting and leveraging latent content features from document resources within the Materials Research domain. We extend the software functionality capability to the domain of scientific literature with emphasis on the expansion of gazetteer lists, named entity rules, natural language construct labeling (e.g. synonym, antonym, hyponym, etc.) efforts to enable extraction of latent content features from data hosted by wide variety of scientific literature vendors (AGU Meeting Abstract Database, Springer, Wiley Online, Elsevier, etc.) hosting earth science literature. Such literature makes both implicit and explicit references to NASA datasets and relationships between such concepts stored across EOSDIS DAAC's hence we envisage that a significant part of this effort will also include development and understanding of relevancy signals which can ultimately

    Directory of Open Access Journals (Sweden)

    Richard M. Bañez

    2016-11-01

    Full Text Available Pedagogical questions on whether recency or relevance of literary texts, and the importance of generic academic over discipline-based learning objectives as the core of literature instruction are increasingly becoming the interest of debates in senior high school education. Hence, this study determined the degree of importance of literary instruction in preparation for college education and workplace challenges as assessed by 38 Grade 11 students at Malvar Senior High School, Philippines during the school year 2016-2017. By employing the survey type of descriptive research with a self-made questionnaire, it was found out that the respondents assessed both recency and relevance as important consideration in selecting literary texts. They also perceived that discipline-based/work-oriented learning objectives, especially those that focus on honing their human relation skills, were relevant in preparing themselves for college education and workplace responsibilities. Moreover, the respondents preferred language-based activities that tend to provide the former opportunities and develop other complex skills which are important in tertiary education and workplace challenges. With these, revitalizing the literature instruction in the senior high school is highly recommended in this study.

    Science.gov (United States)

    Alvares, Luísa; Moreira, Isabel; Oliveira, António

    2007-01-01

    Although previous studies show that physicians generally agree that nutrition knowledge is important for their daily clinical practice, several other studies report their poor knowledge of the subject. One of the strongest reasons given for this is the non-incorporation of Nutrition as a compulsory subject for the medical sciences degree. Dietary counselling and assessment of the patients' nutritional status don't seem to be systematic. The aim of this study is to asses how relevant physicians consider Nutrition to be in the successful running of a good practice. The study was undertaken at the general hospital of Vila Real/Peso da Régua (CHVR/PR) by distribution of a self- administered questionnaire to 153 of the physicians of the clinical body. Mean values were compared with the Student's t test and proportions with the Chi-square test. Of the 153 physicians, 108 replies were received (70,6%). Of these 108 replies, 53,3% consider nutrition knowledge important although 29,6% state their knowledge is poor. More than half say that Clinical Nutrition should be a compulsory subject of the Medical Sciences syllabus, and 99,1% deem it important to assess the patient's nutritional status. About 95% stated they provided written or verbal nutritional guidance, and most of the physicians had already sought the assistance of a nutritionist. This study shows that the clinical body of the CHVR/PR is aware of the importance nutrition knowledge has in their daily practice. It must be noted, though, that although almost one third of the physicians rate their nutrition knowledge poor, most of them provide nutritional guidance to their patients.

  10. A comprehensive survey of retracted articles from the scholarly literature.

    Science.gov (United States)

    Grieneisen, Michael L; Zhang, Minghua

    2012-01-01

    The number of retracted scholarly articles has risen precipitously in recent years. Past surveys of the retracted literature each limited their scope to articles in PubMed, though many retracted articles are not indexed in PubMed. To understand the scope and characteristics of retracted articles across the full spectrum of scholarly disciplines, we surveyed 42 of the largest bibliographic databases for major scholarly fields and publisher websites to identify retracted articles. This study examines various trends among them. We found, 4,449 scholarly publications retracted from 1928-2011. Unlike Math, Physics, Engineering and Social Sciences, the percentages of retractions in Medicine, Life Science and Chemistry exceeded their percentages among Web of Science (WoS) records. Retractions due to alleged publishing misconduct (47%) outnumbered those due to alleged research misconduct (20%) or questionable data/interpretations (42%). This total exceeds 100% since multiple justifications were listed in some retraction notices. Retraction/WoS record ratios vary among author affiliation countries. Though widespread, only miniscule percentages of publications for individual years, countries, journals, or disciplines have been retracted. Fifteen prolific individuals accounted for more than half of all retractions due to alleged research misconduct, and strongly influenced all retraction characteristics. The number of articles retracted per year increased by a factor of 19.06 from 2001 to 2010, though excluding repeat offenders and adjusting for growth of the published literature decreases it to a factor of 11.36. Retracted articles occur across the full spectrum of scholarly disciplines. Most retracted articles do not contain flawed data; and the authors of most retracted articles have not been accused of research misconduct. Despite recent increases, the proportion of published scholarly literature affected by retraction remains very small. Articles and editorials

    Full Text Available In view of the tremendous potential benefits of clinical information systems (CIS for the quality of patient care; it is hard to understand why not every CIS is embraced by its targeted users, the physicians. The aim of this study is to propose a framework for assessing hospital physicians' CIS-acceptance that can serve as a guidance for future research into this area. Hereto, a review of the relevant literature was performed in the ISI Web-of-Science database. Eleven studies were withheld from an initial dataset of 797 articles. Results show that just as in business settings, there are four core groups of variables that influence physicians' acceptance of a CIS: its usefulness and ease of use, social norms, and factors in the working environment that facilitate use of the CIS (such as providing computers/workstations, compatibility between the new and existing system.... We also identified some additional variables as predictors of CIS-acceptance.

    Full Text Available Phishing is the fraudulent acquisition of personal information like username, password, credit card information, etc. by tricking an individual into believing that the attacker is a trustworthy entity. It is affecting all the major sector of industry day by day with lots of misuse of user’s credentials. So in today online environment we need to protect the data from phishing and safeguard our information, which can be done through anti-phishing tools. Currently there are many freely available anti-phishing browser extensions tools that warns user when they are browsing a suspected phishing site. In this paper we did a literature survey of some of the commonly and popularly used anti-phishing browser extensions by reviewing the existing anti-phishing techniques along with their merits and demerits.

  15. Very Short Literature Survey From Supervised Learning To Surrogate Modeling

    CERN Document Server

    Brusan, Altay

    2012-01-01

    The past century was era of linear systems. Either systems (especially industrial ones) were simple (quasi)linear or linear approximations were accurate enough. In addition, just at the ending decades of the century profusion of computing devices were available, before then due to lack of computational resources it was not easy to evaluate available nonlinear system studies. At the moment both these two conditions changed, systems are highly complex and also pervasive amount of computation strength is cheap and easy to achieve. For recent era, a new branch of supervised learning well known as surrogate modeling (meta-modeling, surface modeling) has been devised which aimed at answering new needs of modeling realm. This short literature survey is on to introduce surrogate modeling to whom is familiar with the concepts of supervised learning. Necessity, challenges and visions of the topic are considered.

    LaBelle, S.J.

    1980-03-01

    A survey and an evaluation of recent studies of transportation systems done in a technology-assessment framework were undertaken as the basis for a detailed statement of work for a US Department of Energy technology assessment of transportation energy-conservation strategies. Several bibliographies were searched and numerous professionals in the field of technology assessment were contacted regarding current work. Detailed abstracts were prepared for studies judged to be sufficiently broad in coverage of impacts assessed, yet detailed in coverage of all or part of the nation's transportation systems. Some studies were rich in data but not comprehensive in their analytical approach; brief abstracts were prepared for these. An explanation of the criteria used to screen the studies, as well as abstracts of 37 reports, are provided in this compendium of transportation-technology-assessment literature.

    2012-07-01

    Full Text Available The retromolar foramen is a hole accessory jaw in the retromolar trigone zone. The knowledge of this variation is important for the presence of anatomical structures that enter via the foramen and can serve as via local anesthetic or be affected during surgical procedures. Objective: To determine the frequency of the retromolar foramen in dried humans mandibles and its association with local anesthesia reviewed in scientific literature. Methods: A descriptive study by systematic literature review. We analyzed articles related to the location of retromolar foramina in the MEDLINE and SciELO databases. Author name, sample number, gender, frequency and source side foramina were registred. We analyzed the clinic relevance about to presence of the retromolar foramen. Results: 55 articles, of which only 5(9% were selected. Between 40 to 475 mandibles humans was analized which the presence of the retromolar foramen ranged between 7.8% and 25%. The authors define the use of the foramen for the application of anesthetic techniques and ancillary care in third molar surgery. Conclusion: Accessory foramina occurs in a low percentage. However, it could be an important element for local anesthesia or surgical treatment of the area.

Extensive bibliographies of the technical literature and patents are given. Many passive and active techniques were examined for pure refrigerants, refrigerant-oil mixtures, and refrigerant mixtures. The citations were categorized according to enhancement technique, heat transfer mode, and tube or shell side focus. The effects of the enhancement techniques relative to smooth and/or pure refrigerants were illustrated through the discussion of selected papers. Patented enhancement techniques also are discussed. Enhanced heat transfer has demonstrated significant improvements in performance in many refrigerant applications. However, refrigerant mixtures and refrigerant-oil mixtures have not been studied extensively; no research has been performed with enhanced refrigerant mixtures with oil. Most studies have been of the parametric type; there has been inadequate examination of the fundamental processes governing enhanced refrigerant heat transfer, but some modeling is being done and correlations developed. It is clear that an enhancement technique must be optimized for the refrigerant and operating condition. Fundamental processes governing the heat transfer must be examined if models for enhancement techniques are to be developed; these models could provide the method to optimize a surface. Refrigerant mixtures, with and without oil present, must be studied with enhancement devices; there is too little known to be able to estimate the effects of mixtures (particularly NARMs) with enhanced heat transfer. Other conclusions and recommendations are offered.

  19. Energy and the social sciences. A preliminary literature survey

    Energy Technology Data Exchange (ETDEWEB)

    Sommers, P.

    1975-01-01

    The social science literature pertaining to energy problems is reviewed, and preliminary suggestions for research projects and research strategy are presented. Much of the social science literature on energy is in the field of economics, where such themes as econometric models, pricing policy, taxation, and government-industry interactions are discussed. Among the suggested research efforts is a study of proper economic criteria for determining rates of development of alternative sources of energy. The political science literature on energy is not well developed, but a review of it indicates interesting possibilities for research. The kinds of social and political institutions that would be most effective in an energy-constrained economy should be studied, and a comparative study of institutions now in existence in the United States and other countries is suggested. The social effects of centralized, comprehensive decision-making, which might be necessary in the event of significant shortages of energy, should be studied. The roles of community groups, interest groups, the media, government, etc., in decision-making should receive continuing attention. In the fields of sociology and psychology there is a need for more understanding of the attitudes, beliefs, and behavior of individuals about energy matters. The ways in which people adapt to energy shortages and changes in energy prices should be a subject for continuing studies. It is suggested that plans be made for surveys of coping strategies under emergency conditions as well as under conditions of gradual change. A possible long-range reaction to energy shortages and high prices might be a decrease in living-space available to individuals and families, and the work of psychologists in this area should be analyzed. 41 references.

  20. Energy conservation by hyperfiltration: food industry background literature survey

    Energy Technology Data Exchange (ETDEWEB)

    1980-04-15

    The application of hyperfiltration to selected food product streams and food processing wastewaters for energy conservation was examined. This literature survey had led to the following conclusions: no research has been conducted in the food industry using membranes with hot process streams due to the temperature limitation (< 40/sup 0/C) of the typically studied cellulose acetate membranes; based on the bench-scale research reviewed, concentration of fruit and vegetable juices with membranes appears to be technically feasible; pretreatment and product recovery research was conducted with membranes on citrus peel oil, potato processing and brine wastewaters and wheys. The experiments demonstrated that these applications are feasible; many of the problems that have been identified with membranes are associated with either the suspended solids or the high osmotic pressure and viscosity of many foods; research using dynamic membranes has been conducted with various effluents, at temperatures to approx. 100/sup 0/C, at pressures to 1200 psi and with suspended solids to approx. 2%; and, the dynamic membrane is being prototype tested by NASA for high temperature processing of shower water. The literature review substantiates potential for dynamic membrane on porous stainless tubes to process a number of hot process and effluent streams in the food processing industry. Hot water for recycle and product concentrations are major areas with potential for economic application. The two plants involved in the first phase of the project should be reviewed to identify potential energy conservation applications. As many as possible of the conservation applications should be tested during the screening phase at each site. The most promising applications at each site should be evaluated more intensively to establish engineering estimates of the economics of this technology for the canned fruit and vegetable segment of the food industry.

    Full Text Available Although young science, marketing has passed through the row of changes since the start of its development. The 1990th of the last century brought big changes, firstly by the powerful penetration of information and communication technology. This trend has exerted influences on the development and application of marketing in both theory and practice. Thanks to the development and implementation of CRM systems, companies have had insight into the complete behavior of their customers, even in the situations where companies have a great number of different customers. However, many companies have not used these data in the right way. The work points to some of possible approaches in using data collected by means of CRM systems. Measuring the customer lifetime value, classification of the present customers, increasing customer retention rate, winning new "right" customers and the increase of product sale to the present customers are just some of activities exerting direct influence on companies' business performance. Based on the survey of available literature, the work presents how to use the mentioned activities in the right way.

    2012-07-01

    This article surveys efforts on text mining of the pharmacogenomics literature, mainly from the period 2008 to 2011. Pharmacogenomics (or pharmacogenetics) is the field that studies how human genetic variation impacts drug response. Therefore, publications span the intersection of research in genotypes, phenotypes and pharmacology, a topic that has increasingly become a focus of active research in recent years. This survey covers efforts dealing with the automatic recognition of relevant named entities (e.g. genes, gene variants and proteins, diseases and other pathological phenomena, drugs and other chemicals relevant for medical treatment), as well as various forms of relations between them. A wide range of text genres is considered, such as scientific publications (abstracts, as well as full texts), patent texts and clinical narratives. We also discuss infrastructure and resources needed for advanced text analytics, e.g. document corpora annotated with corresponding semantic metadata (gold standards and training data), biomedical terminologies and ontologies providing domain-specific background knowledge at different levels of formality and specificity, software architectures for building complex and scalable text analytics pipelines and Web services grounded to them, as well as comprehensive ways to disseminate and interact with the typically huge amounts of semiformal knowledge structures extracted by text mining tools. Finally, we consider some of the novel applications that have already been developed in the field of pharmacogenomic text mining and point out perspectives for future research.

    Our objective was to assess the reported reasons for episiotomy performance in Israel and to review the relevant professional literature. Using anonymous questionnaires, a survey was conducted among obstetricians and midwives in four northern Israel hospitals, and the accoucheurs were asked to score their agreement with 13 proposed indications for episiotomy. Overall, 84 doctors and 32 midwives completed the questionnaires. 86.1% of the responders reported performing episiotomy in all or most cases of shoulder dystocia, and more than half reported performing it in most cases of vacuum deliveries, fetal macrosomia and advanced perineal tear in previous delivery. Subjective assessment of perineal characteristics constituted a justified reason for episiotomy for 15.8-43.9% of the accoucheurs. In conclusion, there is a wide variation in reported reasons for episiotomy between the obstetricians, and many of these indications are not congruent with international practice guidelines. Uniform protocols and educational programmes are needed to guide episiotomy practice.

    Articles published in both the American Journal of Community Psychology and Journal of Community Psychology, from their inception in 1973 through 1997, were content analyzed for women relevance, diversity, feminism, and historical change. Overall, 9.8% of the articles reviewed (N = 2,178) were considered women relevant, 4% recognized diversity among women, and 3% were considered feminist. There was an average yearly increase in women-relevant and feminist articles from 7.3 pre-1990 to 11.2 post-1990, and 1.6 pre-1990 to 4.6 post-1990, respectively. Overall, mental health and motherhood were the most addressed content areas. Among feminist articles, gender roles and violence against women were most salient. Race and SES were the most noted issues of diversity in both women-relevant and feminist articles. While an increase in feminist publications by both journals is promising, stereotypes of women and other oppressed groups continue to be perpetuated.

  9. A survey and critical review of the literature on indoor air quality, ventilation and health symptoms in schools

    1998-03-01

    A survey and critical review were undertaken of existing published literature and reports on indoor air quality (IAQ), ventilation, and IAQ- and building-related health problems in schools, including California schools. Over 450 relevant publications were obtained and reviewed, including papers published in the archival peer-reviewed scientific literature, proceedings of scientific meetings, government reports, 77 NIOSH Health Hazard Evaluation Reports (HHER) and 70 reports on investigations of problem schools in California. Most of the reviewed literature was for complaint or problem schools. The types of health symptoms reported in schools were very similar to those defined as sick building syndrome (SBS) symptoms, although this may be due, at least in part, to the type of health symptom questionnaires used. Some of the symptoms, e.g., wheezing, are indicative of asthma. In the studies in which complaint and noncomplaint buildings or areas were compared, complaint buildings generally had higher rates of health symptoms.

  13. Pre-arrest diversion of people with mental illness: Literature review and international survey.

    Hartford, Kathleen; Carey, Robert; Mendonca, James

    2006-01-01

    Mental health diversion is a process where alternatives to criminal sanctions are made available to persons with mental illness (PMI) who have come into contact with the law. One form of mental health diversion is pre-arrest, in which the police use their discretion in laying charges. Concomitant with the growth of pre-arrest diversion programs is a growing body of research devoted to the phenomenon. The purpose of this paper is to review the existing literature of pre-arrest diversion, and to report the results of an international survey of pre-arrest diversion programs we conducted to identify evidence-based practices. On the basis of our review and survey, we note that successful pre-trial programs appear to integrate relevant mental health, substance abuse and criminal justice agencies by having regular meetings between key personnel from the various agencies. Often, a liaison person with a mandate to effect strong leadership plays a key role in the coordination of various agencies. Streamlining services through the creation of an emergency drop-off center with a no-refusal policy for police cases is seen as crucial. While there is some indication that mentally ill offenders benefit from their participation in this form of diversion, the evaluative literature has not yet achieved the "critical mass" necessary to create generalizable, evidence-based knowledge. The absence of generally agreed-upon outcomes could lead to the inequitable application of basic principles of diversion. We suggest that indicators, benchmarks, and outcomes must be agreed upon if a comprehensive understanding of pre-arrest programs is to emerge.

    The aim of this study is to analyze biomedical publications on health surveys (HS) in the Catalan territory from documents published in various bibliographic databases to 2010. Analysis of 1,287 HS documents on 3 bibliographic sources of information relating to Catalonia, between 1991 and 2010. Scientific papers on HS in the Catalan territory have been 196. We studied the variables related to the topic of the article published, the magazine publication of the survey, the characteristics of sampling and the sample size, geographical area and timing of the survey. The articles reviewed represent 15.23% of all original documents. Half of them have been published in Spanish journals, stressing Gaceta Sanitaria and Medicina Clínica and the most studied issues are health and lifestyles. A 40.8% clearly explicit the characteristics of the sample, the size of them range between 49 and 23,126 individuals. It is suggested that HS in Catalonia are useful for generating knowledge about health, lifestyle and health resource utilization of the population, and its disclosure among health experts and the public.

    Thousands of workers in the Netherlands are exposed to dust in the grain handling, storage, and processing industry. The publication summarizes the literature and the effects of graindust on health, which may contain (apart from the grain) molds, bacteria, insects, mycotoxins, and pesticides. A number of mortality studies indicate an elevated risk of some cancer types. It is, however, not clear whether the grain dust itself is responsible for the excess mortality or its constituents. Respiratory effects are reported in a lot of studies. For instance, respiratory and feverish symptoms are indicative for extrinsic allergic alveolitis and grain fever.

    Extrapulmonary metastasis, particularly abdominal metastasis from osteogenic sarcoma, are rare and generally appear as a solid mass of calcification as the primary tumor. The aim of this case report is to document the incidence, characteristics, treatment, and prognosis of abdominal metastasis in osteosarcomas in a single institution and to review the literature. From September 1989 to December 2002, 94 children ≤16 years of age with osteosarcomas were diagnosed and treated in the Division of Pediatric Oncology, Oncology Institute, Istanbul University. Patients with abdominal metastasis were assessed. Two girls of 94 patients (2.1%) with osteosarcoma developed abdominal metastasis. One had pulmonary metastasis at diagnosis and the other had developed lung metastasis 15 months after diagnosis. They developed abdominal metastasis 4 and 3 years after diagnosis during therapy or relapse at a median duration of 16 months (1-70 months) from initial diagnosis. All patients had metastasis to various sites, mostly lung, at the time the abdominal metastasis were detected. Treatment included surgery, chemotherapy, and radiotherapy in one and only surgery in the other patient. Both patients died at a median time of 4 months (2-6 months) from the time of abdominal metastasis with progressive disease. Abdominal metastasis in osteosarcoma is a rare event, but abdomen should be investigated in case of recurrence from osteosarcoma. The outcome for these patients is dismal in this series and in the literature.

    Performance of long-range energy system analyses requires the capability to project conventional domestic oil and gas supplies in the long term. The objective of the Long-range Forecasting Methodology project is to formulate an approach to this problem which will be compatible with the principal tool employed by the Energy Information Administration of the Department of Energy for long-range energy system analyses, the Long-term Energy Analysis Package (LEAP). This paper reports on projection methodologies that have appeared in the literature, evaluates them in terms of their applicability to the LEAP framework, and discusses the principal determinants of conventional domestic oil and gas supply in the long run.

    2005-08-13

    Along with my usual weekly review of the published literature for new nuclear data, I also search for new candidates for best measurements of isotopic abundances from a single source. Most of the published articles, that I previously had found in the Research Library at the Brookhaven Lab, have already been sent to the members of the Atomic Weights Commission, by either Michael Berglund or Thomas Walczyk. In the last few days, I checked the published literature for any other articles in the areas of natural variations in isotopic abundance ratios, measurements of isotopic abundance ratios on samples of extra-terrestrial material and isotopic abundance ratio measurements performed using ICPMS instruments. Hopefully this information will be of interest to members of the Commission, the sub-committee on isotopic abundance measurements (SIAM), members of the former sub-committee on natural isotopic fractionation (SNIF), the sub-committee on extra-terrestrial isotope ratios (SETIR), the RTCE Task Group and the Guidelines Task Group, who are dealing with ICPMS and TIMS comparisons. In the following report, I categorize the publications in one of four areas. Measurements performed using either positive or negative ions with Thermal Ionization Mass Spectrometer, TIMS, instruments; measurements performed on Inductively Coupled Plasma Mass Spectrometer, ICPMS, instruments; measurements of natural variations of the isotopic abundance ratios; and finally measurements on extra-terrestrial samples with instrumentation of either type. There is overlap in these areas. I selected out variations and ET results first and then categorized the rest of the papers by TIMS and ICPMS.

    2010-01-01

    Mining Time Series data has a tremendous growth of interest in today's world. To provide an indication various implementations are studied and summarized to identify the different problems in existing applications. Clustering time series is a trouble that has applications in an extensive assortment of fields and has recently attracted a large amount of research. Time series data are frequently large and may contain outliers. In addition, time series are a special type of data set where elements have a temporal ordering. Therefore clustering of such data stream is an important issue in the data mining process. Numerous techniques and clustering algorithms have been proposed earlier to assist clustering of time series data streams. The clustering algorithms and its effectiveness on various applications are compared to develop a new method to solve the existing problem. This paper presents a survey on various clustering algorithms available for time series datasets. Moreover, the distinctiveness and restriction ...

    Hydrogen is the fuel of the future mainly due to its high conversion efficiency, recyclability and nonpolluting nature. Biological hydrogen production processes are found to be more environment friendly and less energy intensive as compared to thermochemical and electrochemical processes. They are mostly controlled by either photosynthetic or fermentative organisms. Till today, more emphasis has been given on the former processes. Nitrogenase and hydrogenase play very important roles. Genetic manipulation of cyanobacteria (hydrogenase negative gene) improves the hydrogen generation. The paper presents a survey of biological hydrogen production processes. The micro-organism and biochemical pathways involved in hydrogen generation processes are presented in some detail. Several developmental works are discussed. Immobilised system is found suitable for the continuous hydrogen production. About 28% of energy can be recovered in the form of hydrogen using sucrose as substrate. Fermentative hydrogen production processes have some edge over the other biological processes. (Author)

  8. EFL/ESL Textbook Selection in Korea and East Asia - Relevant Issues and Literature Review

    Science.gov (United States)

    Meurant, Robert C.

    EFL/ESL departments periodically face the problem of textbook selection. Cogent issues are that non-native speakers will use L2 English mainly to communicate with other non-native English speakers, so an American accent is becoming less important. L2 English will mainly be used in computer-mediated communication, hence the importance of L2 Digital Literacy. The convergence of Information Communication Technologies is radically impacting Second Language Acquisition, which is integrating web-hosted Assessment and Learning Management Systems. EFL/ESL textbooks need to be compatible with blended learning, prepare students for a globalized world, and foster autonomous learning. I summarize five papers on EFL/ESL textbook evaluation and selection, and include relevant material for adaptation. Textbooks are major sources of contact with the target language, so selection is an important decision. Educators need to be systematic and objective in their approach, adopting a selection process that is open, transparent, accountable, participatory, informed and rigorous.

More importantly, learning is purposeful and not randomised. This explains why, at the end of any learning process, it is essential to gauge the extent to which learning has actually occurred. The literature reveals that this can be done through pre-specifying the learning objectives (objectives model or using an open-ended approach in which objectives are not specified at all (process model. This paper argues that as students learn Geography through fieldwork, the decision to use the former or latter model is immaterial because what matters most is how much effective learning takes place rather than the model used in the lesson preparation process. The guiding principle, therefore, should be on meaningful learning, which is the ultimate goal of all sound educational processes and not whether objectives have been specified or not.

  11. Native Breath: Incorporating Linguistically Relevant Pedagogy in the Classroom through Reified Literature

    Full Text Available  The native breath of linguistic minority students, including speakers of vernaculars and dialects, has traditionally been stifled in classroom ecologies that perpetuate the hegemony of English. A model of linguistically relevant pedagogy is articulated that empowers students both native and nonnative to the Standard to develop cultural competence and critical consciousness towards language. This potentially results in improved native breath valuation and paving the road for improved academic outcomes and facility in learning the societal Standard language as well as gaining tools required in the global age. Drawing from the LIAD (Nero, 2005 and Dialect Awareness (Adger, Wolfram & Christian, 2006 pedagogical frameworks, this paper proposes ways in which educators can support linguistically relevant pedagogy through the teaching of "canonized" fiction.Keywords: bilingualism, culture, literacyThe language I have learn’ed these forty years,my native English I must forgo;and now my tongues use is to me no moreThan an unstringed viol or a harp,Or like a cunning instrument cased up,Or, being open, put into his handsThat knows no touch to tune the harmony:Within my mouth you have engao’ld my tongueDoubly portcullis’d with my teeth and lips;And dull unfeeling barren ignoranceIs made my gaoler to attend on meI am too old to fawn upon a nurse,Too far in years to be a pupil now:What is thy sentence then but speechless death,Which robs my tongue from breathing native breath-Mowbray, Richard II, Act 1 scene 3 (Shakespeare, W.  1595

  12. Interpatient Variability in Dexmedetomidine Response: A Survey of the Literature

    2014-01-01

    Full Text Available Fifty-five thousand patients are cared for in the intensive care unit (ICU daily with sedation utilized to reduce anxiety and agitation while optimizing comfort. The Society of Critical Care Medicine (SCCM released updated guidelines for management of pain, agitation, and delirium in the ICU and recommended nonbenzodiazepines, such as dexmedetomidine and propofol, as first line sedation agents. Dexmedetomidine, an alpha-2 agonist, offers many benefits yet its use is mired by the inability to consistently achieve sedation goals. Three hypotheses including patient traits/characteristics, pharmacokinetics in critically ill patients, and clinically relevant genetic polymorphisms that could affect dexmedetomidine response are presented. Studies in patient traits have yielded conflicting results regarding the role of race yet suggest that dexmedetomidine may produce more consistent results in less critically ill patients and with home antidepressant use. Pharmacokinetics of critically ill patients are reported as similar to healthy individuals yet wide, unexplained interpatient variability in dexmedetomidine serum levels exist. Genetic polymorphisms in both metabolism and receptor response have been evaluated in few studies, and the results remain inconclusive. To fully understand the role of dexmedetomidine, it is vital to further evaluate what prompts such marked interpatient variability in critically ill patients.

    2012-01-01

    The central collision between two solid spheres or the normal collision between a sphere and a plate are important to understand in detail before studying more complex particle interactions. Models exist to describe this basic problem but are not always consistent with available experiments. An interesting benchmark to compare models and experiments is the relation between the normal coefficient of restitution e and the incident velocity v. In order to draw a broad comparison between experiments and models (Krijt, S., Tielens, A.G.G.M., G\\"uttler, C., Hei{\\ss}elmann, D., Dominik, C., Phys. Rev. E, submitted), we provide in this article an overview on the literature describing experiments on normal collisions, preferably providing data on e(v). We will briefly summarize our expectation on this relation according to an established collision model in order to classify these experiments. We will then provide an overview on experimental techniques, which we found in the summarized articles, as well as a listing of...

    As the importance of systematic review (SR) conclusions relies upon the scientific rigor of methods and the currency of evidence, we aimed to investigate the currency of orthodontic SRs using as proxy the time from the initial search to publication. Additionally, SR information regarding reporting guidelines, registration, and literature searches were recorded when available. A systematic PubMed search was carried out using the Clinical Queries page to identify orthodontic SRs cited between 1 January 2008 and 7 November 2013. Data related to reporting guidelines, review registration, dates of review processing, literature search, and abstract reporting were retrieved and classified by journal type. Survival analysis was used to assess the time to reach predefined manuscript stages for orthodontic and non-orthodontic journals. One hundred twenty seven of the originally identified 585 SRs were considered eligible. The median interval from search until publication was 13.2 months (interquartile range: IQR = 9.7 months) irrespective of the journal type. There was evidence (P = 0.05) that SRs published by non-orthodontic journals appeared in PubMed faster than in orthodontic journals (non-orthodontic: median = 6.5 months; IQR = 5.7 months; orthodontic: median = 10.2 months; IQR = 5.6 months) from submission to publication and from acceptance to publication (non-orthodontic: median = 1.5 months; IQR = 2.4 months; orthodontic: median = 6.0 months; IQR = 6.2 months; P orthodontic and orthodontic periodicals, respectively. This study indicates that SR users should be aware that median time for orthodontic SRs from search to publication is 13.2 months. SRs published in non-orthodontic journals are likely to be more current in terms of submission until time to publication and acceptance until time to publication compared with those published in orthodontic journals. © The Author 2014.

    This study aimed to investigate the systemic antibiotic usage in the perioperative period of periodontal flaps and its relevance to the infection after surgeries through reviewing the papers of the last decade. A search was conducted for the studies of randomized clinical trials between 2005 and 2014 that reported periodontal flaps in chronic periodontitis patients. Data were extracted and the rate of the systemic antibiotic use, the infection rate after surgeries and the number needed to treat (NNT) to prevent one infected case were calculated. The impact of antibiotic use and materials used in surgeries on the infection was evaluated. Eighty-three trials were included. Antibiotics were used in 73.7% of the patients and 75.4% of the flaps. Infection occurred in only five flaps where enamel matrix proteins (EMD) or EMD + bone grafts were used in intrabony defects. Only 0.170% of the surgeries got infected in total. When all kinds of surgeries were included for analysis, the infection rate was 0.073% for the surgeries using antibiotics, which was lower than the infection rate 0.693% for the surgeries not using antibiotics (p antibiotics and not might lack clinical significance. Considering the very low incidence of the infection and the disadvantages of the systemic antibiotic use, we suggest not using systemic antibiotics in the perioperative period of periodontal flaps to prevent infection.

    Full Text Available Nanoinformatics is an emerging research field that uses informatics techniques to collect, process, store, and retrieve data, information, and knowledge on nanoparticles, nanomaterials, and nanodevices and their potential applications in health care. In this paper, we have focused on the solutions that nanoinformatics can provide to facilitate nanotoxicology research. For this, we have taken a computational approach to automatically recognize and extract nanotoxicology-related entities from the scientific literature. The desired entities belong to four different categories: nanoparticles, routes of exposure, toxic effects, and targets. The entity recognizer was trained using a corpus that we specifically created for this purpose and was validated by two nanomedicine/nanotoxicology experts. We evaluated the performance of our entity recognizer using 10-fold cross-validation. The precisions range from 87.6% (targets to 93.0% (routes of exposure, while recall values range from 82.6% (routes of exposure to 87.4% (toxic effects. These results prove the feasibility of using computational approaches to reliably perform different named entity recognition (NER-dependent tasks, such as for instance augmented reading or semantic searches. This research is a “proof of concept” that can be expanded to stimulate further developments that could assist researchers in managing data, information, and knowledge at the nanolevel, thus accelerating research in nanomedicine.

    2013-07-01

    Full Text Available Transcutaneous electric nerve stimulation (TENS is a standard therapy used in different painful conditions such as low back pain, diabetic polyneuropathy or arthrosis. However, literature reviews focusing on the effects and the clinical implication of this method in various painful conditions are yet scarce. The purpose of this literature research was to determine, whether TENS provides an analgesic effect on common painful conditions in clinical practice. Literature research was performed using three data bases (Pubmed, Embase, Cochrane Database, focusing on papers published in the space of time from 2007 to 2012. Papers were evaluated from two reviewers independently concerning the clinical outcome, taking account for the level of external evidence according to the German Cochrane levels of evidence (Ia – IV. 133 papers of varying methodological quality dealing with different painful conditions were selected in total. A clinically relevant analgesic effect was described in 90 painful conditions (67%. In 30 painful states (22%, the outcome was inconclusive due to the study design. No significant analgesic effect of TENS was observed in 15 painful conditions (11%. The vast majority of the papers were classified as Cochrane evidence level Ib (n = 64; 48%, followed by level Ia (n = 23; 17%, level III (n = 18; 14%, level IV (n = 15; 11%, level IIb (n = 10; 8% and level IIa (n = 3; 2%. Most of the studies revealed an analgesic effect in various painful conditions, confirming the usefulness of TENS in clinical practice.

    2000-05-01

    Organ donation provides a second chance for those who have experienced severe disease or injury. Unfortunately there is a huge discrepancy between the supply and demand of transplantable organs, despite the existence of sufficient numbers of potential donors. Through a review of the literature and a survey of optometry students, this article provides insight into the reasons for the shortage of corneal donors and how more corneal donors might be obtained. A survey of 200 optometry students at the University California, Berkeley, School of Optometry was conducted to augment the literature review. Seventy-six students (38% of those surveyed) completed the survey process. Results of the survey indicated that 64.5% of who responded were willing to donate body organs, while 31.6% were not. Of those not willing to donate organs, 11.8% cited religious reasons. Other personal reasons included: fear (4%), respect for the human body (7.9%), and parental disapproval (6.4%). Only 46.1% of respondents had donation stickers on their driver's licenses. The literature review and survey indicate that age, religion, culture, personality characteristics, views on death and mortality, body image, and humanitarian concerns are among the many factors that influence people's opinion concerning organ donations. Education of the public and health care professionals' awareness of the importance of obtaining corneas for donation is crucial to end the shortage of organ donors.

    Patients with dengue fever and comorbidities seem to be at higher risk of developing complications and/or severe dengue compared to healthier individuals. This study systematically reviews the evidence related to comorbidities and dengue. A systematic literature review was performed in five databases (EMBASE, PUBMED, Global Health, SciELO, Cochrane) and grey literature for full-text articles since its inceptions until October 10, 2015. A total of 230 articles were retrieved. Sixteen studies were analysed after applying all inclusion and exclusion criteria. Seven case control studies and nine retrospective cohort studies showed that comorbidities may contribute to severe dengue, especially 1) cardiovascular disease, 2) stroke, 3) diabetes, 4) respiratory disease and 5) renal disease, as well as old age. However, due to heterogeneity in studies, the real estimate effect of comorbidities as modifiers of dengue severity could not be established. Further research in regions with high prevalence of dengue infection would contribute to a better understanding of the relevance of comorbidities in severe dengue, especially with a standardised protocol, for outcomes, specific comorbidities, study design-best using prospective designs-and sample sizes.

    Jensen, K; Gluud, C

    1994-10-01

    To aid understanding of markers of disease and predictors of outcome in alcohol-exposed systems, we undertook a literature survey of more than 700 articles to view the morphological characteristics and the clinical and experimental epidemiology of the Mallory body. Mallory bodies are filaments of intermediate diameter that contain intermediate filament components (e.g., cytokeratins) observable by conventional light microscopy or immunohistochemical methods, identical in structure regardless of initiating factors or putative pathogenesis. Although three morphological types can be identified under electron microscopy (with fibrillar structure parallel, random or absent), they remain stereotypical manifestations of hepatocyte injury. A summary of the conditions associated with Mallory bodies in the literature and their validity and potential etiological relationships is presented and discussed, including estimates on the combined light microscopic and immunohistochemical prevalences and kinetics. Emphasis is placed on proper confounder control (in particular, alcohol history), which is highly essential but often inadequate. These conditions include (mean prevalence of Mallory bodies in parentheses): Indian childhood cirrhosis (73%), alcoholic hepatitis (65%), alcoholic cirrhosis (51%), Wilson's disease (25%), primary biliary cirrhosis (24%), nonalcoholic cirrhosis (24%), hepatocellular carcinoma (23%), morbid obesity (8%) and intestinal bypass surgery (6%). Studies in alcoholic hepatitis strongly suggest a hit-and-run effect of alcohol, whereas other chronic liver diseases show evidence of gradual increase in prevalence of Mallory bodies with severity of hepatic pathology. Mallory bodies in cirrhosis do not imply alcoholic pathogenesis. Obesity, however, is associated with alcoholism and diabetes, and Mallory bodies are only present in diabetic patients if alcoholism or obesity complicates the condition. In addition, case studies on diseases in which Mallory bodies

    In one-third of the patients with amoebiasis, amoebic liver abscess (ALA) may occur after the penetration of amoebic trophozoites through the intestinal wall. ALA is seen mostly among men aged 20-45 years with a serious clinical outcome, with fever and abdominal pain on the right upper quadrant. Most patients have no recent history of amoebic colitis; indeed, they have neither gastrointestinal complaints nor Entamoeba histolytica (E. histolytica) cysts/trophozoites in their stools. Therefore, ultrasonography and serology are primary in ALA diagnosis, while searching for E. histolytica DNA in abscess fluid using PCR has been preferred as an effective and reliable method, lately. Early antimicrobial therapy is effective; however, for cases irresponsive to therapy after 72 hours and with large abscess, drainage or surgical intervention is indicated. If left untreated, ALA may disseminate to other organs and cause death. The data concerning the extra-intestinal manifestations of amebiasis in Turkey are limited. Here, a rare case of a young man with an initial diagnosis of pneumonia followed by the identification of ALA after radiological interventions and laboratory tests is presented and the relevant literature is discussed.

    Literature survey has been performed for a compendium of mechanical properties of carbon and low alloy steels following hydrogen exposure. The property sets include yield strength, ultimate tensile strength, uniform elongation, reduction of area, threshold stress intensity factor, fracture toughness, and fatigue crack growth. These properties are drawn from literature sources under a variety of test methods and conditions. However, the collection of literature data is by no means complete, but the diversity of data and dependency of results in test method is sufficient to warrant a design and implementation of a thorough test program. The program would be needed to enable a defensible demonstration of structural integrity of a pressurized hydrogen system. It is essential that the environmental variables be well-defined (e.g., the applicable hydrogen gas pressure range and the test strain rate) and the specimen preparation be realistically consistent (such as the techniques to charge hydrogen and to maintain the hydrogen concentration in the specimens).

It is essential that the environmental variables be well-defined (e.g., the applicable hydrogen gas pressure range and the test strain rate) and the specimen preparation be realistically consistent (such as the techniques to charge hydrogen and to maintain the hydrogen concentration in the specimens).

    Wounds that exhibit delayed healing add extraordinary clinical, economic, and personal burdens to patients, as well as to increasing financial costs to health systems. New interventions designed to ease such burdens for patients with cancer, renal, or ophthalmologic conditions are often cleared for approval by the U.S. Food and Drug Administration (FDA) using multiple endpoints but the requirement of complete healing as a primary endpoint for wound products impedes FDA clearance of interventions that can provide other clinical or patient-centered benefits for persons with wounds. A multidisciplinary group of wound experts undertook an initiative, in collaboration with the FDA, to identify and content validate supporting FDA criteria for qualifying wound endpoints relevant to clinical practice (CP) and patient-centered outcomes (PCO) as primary outcomes in clinical trials. As part of the initiative, a research study was conducted involving 628 multidisciplinary expert wound clinicians and researchers from 4 different groups: the interdisciplinary core advisory team; attendees of the Spring 2015 Symposium on Advanced Wound Care (SAWC); clinicians employed by a national network of specialty clinics focused on comprehensive wound care; and Association for the Advancement of Wound Care (AAWC) and Wound Healing Society (WHS) members who had not previously completed the survey. The online survey assessed 28 literature-based wound care endpoints for their relevance and importance to clinical practice and clinical research. Fifteen of the endpoints were evaluated for their relevance to improving quality of life. Twenty-two endpoints had content validity indexes (CVI) ≥ 0.75, and 15 were selected as meriting potential inclusion as additional endpoints for FDA approval of future wound care interventions. This study represents an important first step in identifying and validating new measurable wound care endpoints for clinical research and practice and for regulatory

  3. Literature survey of the aqueous chemistry of technetium related to photolysis. [115 references

    Friedman, H.A.

    1981-07-01

    A literature survey was made to accumulate information about the chemistry of technetium as it relates to photolysis. The electrochemical potentials and the reactions of the various technetium compounds and complexes are discussed, along with the various absorption spectra of the different species. The TcCl/sub 6//sup 2 -/ ion has been shown to be photochemically active in HCl solutions. Hexachlorotechnetate(IV) is oxidized when exposed to sunlight in concentrated HCl. A ligand change occurs when it is exposed to either 254- or 34-nm radiation in more dilute HCl. No other photolysis reactions were found in the literature. It is possible that, under appropriate conditions, other valence states of technetium would be photochemically active, resulting in either redox or ligand exchange reactions. Proposals for investigating the photochemical reduction of the pertechnetate in HNO/sub 3/ and other media are discussed.

    The present report is a summary of a literature survey on the stress corrosion cracking (SCC) behaviour/ mechanisms in low-alloy steels (LAS) in high-temperature water with special emphasis to primary-pressure-boundary components of boiling water reactors (BWR). A brief overview on the current state of knowledge concerning SCC of low-alloy reactor pressure vessel and piping steels under BWR conditions is given. After a short introduction on general aspects of SCC, the main influence parameter and available quantitative literature data concerning SCC of LAS in high-temperature water are discussed on a phenomenological basis followed by a summary of the most popular SCC models for this corrosion system. The BWR operating experience and service cracking incidents are discussed with respect to the existing laboratory data and background knowledge. Finally, the most important open questions and topics for further experimental investigations are outlined. (author)

    The economics of dengue is complex and multifaceted. We performed a systematic review of the literature to provide a critical overview of the issues related to dengue economics research and to form a background with which to address the question of cost. Three literature databases were searched [PubMed, Embase and Latin American and Caribbean Health Sciences Literature (LILACS)], covering a period from 1980 to 2013, to identify papers meeting preset inclusion criteria. Studies were reviewed for methodological quality on the basis of a quality checklist developed for this purpose. An expert survey was designed to identify priority areas in dengue economics research and to identify gaps between the methodology and actual practice. Survey responses were combined with the literature review findings to determine stakeholder priorities in dengue economics research. The review identified over 700 papers. Forty-two of these papers met the selection criteria. The studies that were reviewed presented results from 32 dengue-endemic countries, underscoring the importance of dengue as a global public health problem. Cost analyses were the most common, with 21 papers, followed by nine cost-effectiveness analyses and seven cost-of-illness studies, indicating a relatively strong mix of methodologies. Dengue annual overall costs (in 2010 values) ranged from US$13.5 million (in Nicaragua) to $56 million (in Malaysia), showing cost variations across countries. Little consistency exists in the way costs were estimated and dengue interventions evaluated, making generalizations around costs difficult. The current evidence suggests that dengue costs are substantial because of the cost of hospital care and lost earnings. Further research in this area will broaden our understanding of the true economic impact of dengue.

    A literature survey was conducted to collect information and summarize the methods available to capture iodine from fuel reprocessing off-gases. Techniques were categorized as either wet scrubbing or solid adsorbent methods, and each method was generally described as it might be used under reprocessing conditions. Decontamination factors are quoted only to give a rough indication of the effectiveness of the method. No attempt is made to identify a preferred capture method at this time, although activities are proposed that would provide a consistent baseline that would aid in evaluating technologies.

    Salmonella species are common bacterial pathogens associated with human gastroenteritis worldwide. In Japan, salmonellosis is one of the main food-borne bacterial illnesses and, especially, Salmonella Enteritidis infections have been strongly associated with the consumption of eggs and egg-containing foods. In this study, we performed the literature survey of Salmonella contamination in shell eggs and liquid eggs worldwide for comparing the prevalence among the countries and summarized in the tables. This survey clarified that one out of several thousands of retail shell eggs were contaminated with Salmonella spp. in Japan and the prevalence of Salmonella in retail shell eggs were higher in some countries. This paper is useful for providing referable data on Salmonella contamination in shell eggs and liquid eggs in Japan, especially for researchers of other countries.

    Lateral flow (immuno)assays are currently used for qualitative, semiquantitative and to some extent quantitative monitoring in resource-poor or non-laboratory environments. Applications include tests on pathogens, drugs, hormones and metabolites in biomedical, phytosanitary, veterinary, feed/food and environmental settings. We describe principles of current formats, applications, limitations and perspectives for quantitative monitoring. We illustrate the potentials and limitations of analysis with lateral flow (immuno)assays using a literature survey and a SWOT analysis (acronym for "strengths, weaknesses, opportunities, threats"). Articles referred to in this survey were searched for on MEDLINE, Scopus and in references of reviewed papers. Search terms included "immunochromatography", "sol particle immunoassay", "lateral flow immunoassay" and "dipstick assay".

    Matrix diffusion is an important mechanism for solutetransport in fractured rock. We recently conducted a literature survey onthe effective matrix diffusion coefficient, Dem, a key parameter fordescribing matrix diffusion processes at the field scale. Forty fieldtracer tests at 15 fractured geologic sites were surveyed and selectedfor study, based on data availability and quality. Field-scale Dem valueswere calculated, either directly using data reported in the literature orby reanalyzing the corresponding field tracer tests. Surveyed dataindicate that the effective-matrix-diffusion-coefficient factor FD(defined as the ratio of Dem to the lab-scale matrix diffusioncoefficient [Dem]of the same tracer) is generally larger than one,indicating that the effective matrix diffusion coefficient in the fieldis comparatively larger than the matrix diffusion coefficient at therock-core scale. This larger value could be attributed to the manymass-transfer processes at different scales in naturally heterogeneous,fractured rock systems. Furthermore, we observed a moderate trend towardsystematic increase in the emDFmDDF value with observation scale,indicating that the effective matrix diffusion coefficient is likely tobe statistically scale dependent. The FD value ranges from 1 to 10,000for observation scales from 5 to 2,000 m. At a given scale, the FD valuevaries by two orders of magnitude, reflecting the influence of differingdegrees of fractured rock heterogeneity at different sites. In addition,the surveyed data indicate that field-scale longitudinal dispersivitygenerally increases with observation scale, which is consistent withprevious studies. The scale-dependent field-scale matrix diffusioncoefficient (and dispersivity) may have significant implications forassessing long-term, large-scale radionuclide and contaminant transportevents in fractured rock, both for nuclear waste disposal and contaminantremediation.

    The SBBrasil 2010 Project (SBB10) was designed as a nationwide oral health epidemiological survey within a health surveillance strategy. This article discusses methodological aspects of the SBB10 Project that can potentially help expand and develop knowledge in the health field. This was a nationwide survey with stratified multi-stage cluster sampling. The sample domains were 27 State capitals and 150 rural municipalities (counties) from the country's five major geographic regions. The sampling units were census tracts and households for the State capitals and municipalities, census tracts, and households for the rural areas. Thirty census tracts were selected in the State capitals and 30 municipalities in the countryside. The precision considered the demographic domains grouped by density of the overall population and the internal variability of oral health indices. The study evaluated dental caries, periodontal disease, malocclusion, fluorosis, tooth loss, and dental trauma in five age groups (5, 12, 15-19, 35-44, and 65-74 years).

  15. Literature survey and documentation on organic solid deposition problem. Status report

    1993-12-01

    Organic solid deposition is often a major problem in petroleum production and processing. Recently, this problem has attracted more attention because operating costs have become more critical to the profit of oil production. Also, in miscible gas flooding, asphaltene deposition often occurs in the wellbore region after gas breakthrough and causes plugging. The organic deposition problem is particularly serious in offshore oil production. Cooling of crude oil when it flows through long-distance pipelines under sea water may cause organic deposition in the pipeline and result in plugging. NIPER`s Gas EOR Research Project has been devoted to the study of the organic solid deposition problem for three years. NIPER has received many requests for technical support. Recently, the DeepStar project committee on thermo-technology development and standardization has asked NIPER to provide them with NIPER`s expertise and experience. To assist the oil industry, NIPER is preparing a state-of-the-art review on the technical development for the organic deposition problem. In the first quarter, this project has completed a literature survey and documentation. total of 258 publications (114 for wax, 124 for asphaltene, and 20 for related subjects) were collected and categorized. This literature survey was focused on the two subjects: wax and asphaltene. The subjects of bitumen, asphalt, and heavy oil are not included. Also, the collected publications are mostly related to production problems.

  16. Towards harmonisation of critical laboratory result management - review of the literature and survey of australasian practices.

    Timely release and communication of critical test results may have significant impact on medical decisions and subsequent patient outcomes. Laboratories therefore have an important responsibility and contribution to patient safety. Certification, accreditation and regulatory bodies also require that laboratories follow procedures to ensure patient safety, but there is limited guidance on best practices. In Australasia, no specific requirements exist in this area and critical result reporting practices have been demonstrated to be heterogeneous worldwide.Recognising the need for agreed standards and critical limits, the AACB started a quality initiative to harmonise critical result management throughout Australasia. The first step toward harmonisation is to understand current laboratory practices. Fifty eight Australasian laboratories responded to a survey and 36 laboratories shared their critical limits. Findings from this survey are compared to international practices reviewed in various surveys conducted elsewhere. For the successful operation of a critical result management system, critical tests and critical limits must be defined in collaboration with clinicians. Reporting procedures must include how critical results are identified; who can report and who can receive critical results; what is an acceptable timeframe within which results must be delivered or, if reporting fails, what escalation procedures should follow; what communication channels or systems should be used; what should be recorded and how; and how critical result procedures should be maintained and evaluated to assess impact on outcomes.In this paper we review the literature of current standards and recommendations for critical result management. Key elements of critical result reporting are discussed in view of the findings of various national surveys on existing laboratory practices, including data from our own survey in Australasia. Best practice recommendations are made that laboratories

    This paper reports the results of a four-week questionnaire survey carried out at the National Lending Library (N.L.L.), Great Britian, to discover which types of organizations were the principal users of medical literature, what types of literature were used, and which were the main sources of references to medical publications. Industrial organizations and universities accounted for the majority (62 percent) of the loans, most of which were English-language periodicals published since 1960. For the whole sample, citation lists in periodical articles were the principal sources of references, although for literature published in the last fifteen months, abstracting and indexing journals were the main sources. Of the latter, Index Medicus proved to be the most fruitful source of references. By asking whether the item requested was really useful to their work, a measure of the reliability of the different sources of references was obtained. Appendixes include the questionnaire, a list of the most frequently borrowed journals, and a list of abstracting and indexing journals used as sources of references. PMID:5782264

    From a safety perspective, it is difficult to assess the correctness of FPGA devices without extensive documentation, tools, and review procedures. NUREG/CR-6463, "Review Guidelines on Software Languages for Use in Nuclear Power Plant Safety Systems," provides guidance to the Nuclear Regulatory Commission (NRC) on auditing of programs for safety systems written in ten high-level languages. A uniform framework for the formulation and discussion of language-specific programming guidelines was employed. Comparable guidelines based on a similar framework are needed for FPGA-based systems. The first task involves evaluation of regulatory experience gained by other countries and other agencies, and those captured in existing standards, to identify regulatory approaches that can be adopted by NRC. If existing regulations do not provide a sufficient regulatory basis for adopting relevant regulatory approaches that are uncovered, ORNL will identify the gaps. Information for this report was obtained through publicly available sources such as published papers and presentations. No proprietary information is represented.

    The drug information curriculum in US colleges of pharmacy continues to evolve. The American College of Clinical Pharmacy (ACCP) Drug Information Practice and Research Network (DI PRN) published an opinion paper with specific recommendations regarding drug information education in 2009. Adoption of these recommendations has not been evaluated. To assess which recommendations made in the ACCP DI PRN opinion paper are included in US pharmacy school curricula and characterize faculty qualifications, educational methods, and recent changes in drug information education. An electronic survey was designed using the ACCP DI PRN opinion paper and the Accreditation Council for Pharmacy Education standards and guidelines for accreditation of PharmD programs in the US. Survey questions addressed curricular content within the following categories: drug information, literature evaluation, and biostatistics. A letter including the online survey link was sent via email to the dean of each US college/school of pharmacy (N = 128). Recipients were instructed to forward the email to the individual at their institution who was the most knowledgeable about the content and methodology used for didactic drug information education. Sixty-four responses were included in the final analysis. Of the 19 ACCP DI PRN minimum core concepts, 9 (47%) were included in curricula of all responding institutions; 14 of 19 (74%) were included in curricula for all but 1 institution. In contrast, 5 of 16 concepts (31%) were not formally taught by a number of institutions. Many respondents noted an increased focus on evidence-based medicine, medication safety, and informatics. Although a survey of drug information curricula documented substantial inclusion of the essential concepts presented in the ACCP DI PRN opinion paper, room for improvement remains in drug information curricula in US colleges of pharmacy.

    Development of a new technology for commercial application can be significantly accelerated by leveraging related technologies used in other markets. Synergies across multiple application domains attract research and development (R and D) talent - widening the innovation pipeline - and increases the market demand in common components and subsystems to provide performance improvements and cost reductions. For these reasons, driver development plans for inertial fusion energy (IFE) should consider the non-fusion technology base that can be lveraged for application to IFE. At this time, two laser driver technologies are being proposed for IFE: solid-state lasers (SSLs) and KrF gas (excimer) lasers. This document provides a brief survey of organizations actively engaged in these technologies. This is intended to facilitate comparison of the opportunities for leveraging the larger technical community for IFE laser driver development. They have included tables that summarize the commercial organizations selling solid-state and KrF lasers, and a brief summary of organizations actively engaged in R and D on these technologies.

  3. FIELD-SCALE EFFECTIVE MATRIX DIFFUSION COEFFICIENT FOR FRACTURED ROCK:RESULTS FROM LITERATURE SURVEY

    Matrix diffusion is an important mechanism for solute transport in fractured rock. We recently conducted a literature survey on the effective matrix diffusion coefficient, D{sub m}{sup e}, a key parameter for describing matrix diffusion processes at the field scale. Forty field tracer tests at 15 fractured geologic sites were surveyed and selected for the study, based on data availability and quality. Field-scale D{sub m}{sup e} values were calculated, either directly using data reported in the literature or by reanalyzing the corresponding field tracer tests. Surveyed data indicate that the effective-matrix-diffusion-coefficient factor F{sub D} (defined as the ratio of D{sub m}{sup e} to the lab-scale matrix diffusion coefficient [D{sub m}] of the same tracer) is generally larger than one, indicating that the effective matrix diffusion coefficient in the field is comparatively larger than the matrix diffusion coefficient at the rock-core scale. This larger value can be attributed to the many mass-transfer processes at different scales in naturally heterogeneous, fractured rock systems. Furthermore, we observed a moderate trend toward systematic increase in the F{sub D} value with observation scale, indicating that the effective matrix diffusion coefficient is likely to be statistically scale dependent. The F{sub D} value ranges from 1 to 10,000 for observation scales from 5 to 2,000 m. At a given scale, the F{sub D} value varies by two orders of magnitude, reflecting the influence of differing degrees of fractured rock heterogeneity at different sites. In addition, the surveyed data indicate that field-scale longitudinal dispersivity generally increases with observation scale, which is consistent with previous studies. The scale-dependent field-scale matrix diffusion coefficient (and dispersivity) may have significant implications for assessing long-term, large-scale radionuclide and contaminant transport events in fractured rock, both for nuclear waste disposal

    As a one of the solution for the spent nuclear fuel problem, deep repository research have been under way in KAERI. To raise the resistance against repository cask corrosion, copper canister was adopted for the outer material of the cask. Duration of the repository with million year order makes the copper corrosion research under the repository environment very important and the corrosion modelling which could trace the real world precisely and predict the corrosion behavior very well is subsequently necessary. With in progress of plan to manufacture unique copper cask corresponding to our country repository system, survey for the preceding research papers in recent research direction and kernel points is expected to significant. This paper arranged the representative literatures for the important corrosion mechanism which are recently published.

    2016-05-01

    This report on evaporite mineralization was completed as an Ancillary Work Plan for the Applied Studies and Technology program under the U.S. Department of Energy (DOE) Office of Legacy Management (LM). This study reviews all LM sites under Title I and Title II of the Uranium Mill Tailings Radiation Control Act (UMTRCA) and one Decontamination and Decommissioning site to provide (1) a summary of which sites have evaporite deposits, (2) any available quantitative geochemical and mineralogical analyses, and (3) references to relevant reports. In this study, “evaporite” refers to any secondary mineral precipitate that occurs due to a loss of water through evaporative processes. This includes efflorescent salt crusts, where this term refers to a migration of dissolved constituents to the surface with a resulting salt crust, where “salt” can refer to any secondary precipitate, regardless of constituents. The potential for the formation of evaporites at LM sites has been identified, and may have relevance to plume persistence issues. Evaporite deposits have the potential to concentrate and store contaminants at LM sites that could later be re-released. These deposits can also provide a temporary storage mechanism for carbonate, chloride, and sulfate salts along with uranium and other contaminants of concern (COCs). Identification of sites with evaporites will be used in a new technical task plan (TTP), Persistent Secondary Contaminant Sources (PeSCS), for any proposed additional sampling and analyses. This additional study is currently under development and will focus on determining if the dissolution of evaporites has the potential to hinder natural flushing strategies and impact plume persistence. This report provides an initial literature review on evaporites followed by details for each site with identified evaporites. The final summary includes a table listing of all relevant LM sites regardless of evaporite identification.

    A large number of haptic driver support systems have been described in the scientific literature. However, there is little consensus regarding the design, evaluation methods, and effectiveness of these systems. This literature survey aimed to investigate: (1) what haptic systems (in terms of function, haptic signal, channel, and supported task) have been experimentally tested, (2) how these haptic systems have been evaluated, and (3) their reported effects on driver performance and behaviour. We reviewed empirical research in which participants had to drive a vehicle in a real or simulated environment, were able to control the heading and/or speed of the vehicle, and a haptic signal was provided to them. The results indicated that a clear distinction can be made between warning systems (using vibrations) and guidance systems (using continuous forces). Studies typically used reaction time measures for evaluating warning systems and vehicle-centred performance measures for evaluating guidance systems. In general, haptic warning systems reduced the reaction time of a driver compared to no warnings, although these systems may cause annoyance. Guidance systems generally improved the performance of drivers compared to non-aided driving, but these systems may suffer from after-effects. Longitudinal research is needed to investigate the transfer and retention of effects caused by haptic support systems.

    Full Text Available The concept of supply chain management has been evolving at a rapid pace in economic practice as wellas in scientific research, mainly in the field of logistics and supply chains. It also constitutes a reference point for researchers specializing in accounting, especially in management accounting. As a result, in recent years there has been an increasing number of publications on this research in the world, including in Poland. So far, however, there is a lack of publications that would present comprehensively the aspects of management accounting in the context of supply chain management. Therefore, this article has the following research objective: identification of the degree of development of management accounting, in research and practice, for the purposes of supply chain management. As research methods were used:review of the content of scientific articles and surveys conducted among companies in Poland. The results of survey study and literature review revealed that the most frequently addressed issues in business and in theory include cost management and performance measurement using financial indicators. In the case of other issues addressed in the publications there are discrepancies between theory and business practice. In effect, this means the need to improve the communication and integration of these two dimensions in the context of implementation of management accounting tools and methods for supply chain management support. The results presented in the article could be the basis for further, in-depth research in this area.

    This article investigated the value of reader-response theory for the reading of apocryphal texts in the Septuagint. The groundbreaking work on reader-response theory developed by Wolfgang Iser in his book The Act of Reading: A Theory of Aesthetic Response, written in 1978 served as the theoretical point of departure. Although the reader-response theory has been scrutinised and criticised heavily during the last three decades, Iser made a very valuable contribution to the reading of literatur...

    There is an incentive for the power utilities to look for other ways than building new power stations to satisfy increasing customer power needs. One way to fulfill this demand is by redistributing the available electric power between the different power consumers. This method can successfully be used during high peak hours. The utility is also able to make financial profits selling the redistributed electric power at a higher price to customers with temporary high power demands. Direct Load Control - DLC, a Demand Side Management - DSM tool, is one way to achieve a redistribution of electric power. This masters thesis project consisted in developing a user-friendly simulation platform for domestic appliances combined with an electric power control system to be employed for Direct Load Control. The platform contains the necessary facilities for designing an electrical distribution network model and is implemented in G2, an object-oriented real-time environment. The final application provides an on-line instrument for the utility to control the power consumption over the entire system in terms of dispensing power in an electrical network. The report consists of two main parts. The first part describes a literature survey we systematically compiled to gather literature sources. The second part outlines our design and implementation of the G2 simulation platform for a water-heater model with a Direct Load Control system. The entire simulation platform is designed to allow a flexible change and improvement of the different models. Consequently, our software is a powerful tool for studying a wide range of problems related to a Load Management program involving electrical household loads. 9 refs, 32 figs

    To summarize previously published findings and to present the opinions of a group of reconstructive orthopedic surgeons from a single institution on participation in sports after hip or knee arthroplasty. We reviewed the literature pertaining to participation in sports after hip or knee arthroplasty and surveyed a group of orthopedic surgeons about their recommendations for resumption of various sports activities by patients who had undergone total hip or knee arthroplasty. A computerized literature search was performed, and salient issues about participation in sports after joint replacement procedures were synthesized. At the Mayo Clinic, 28 orthopedic surgeons (13 consultants and 15 fellows or residents) completed a single-page questionnaire that requested a recommendation ("yes," "no," or "depends") about patients resuming participation in 28 common sports after recovery from total hip or knee arthroplasty. Staff surgeon responses were compared with responses from fellows and residents by using the Mann-Whitney U test. Sports in which 75% of surgeons would not allow participation were identified as "not recommended," whereas sports in which 75% of surgeons would allow participation were labeled as "recommended." Fellows and residents were less likely than staff surgeons to allow return to cross-country skiing after total knee arthroplasty. Otherwise, responses from consultant surgeons and from fellows and residents did not differ significantly. Recommended sports included sailing, swimming laps, scuba diving, cycling, golfing, and bowling after hip and knee replacement procedures and also cross-country skiing after knee arthroplasty. Sports not recommended after hip or knee arthroplasty were running, waterskiing, football, baseball, basketball, hockey, handball, karate, soccer, and racquetball. After hip or knee arthroplasty, participation in no-impact or low-impact sports can be encouraged, but participation in high-impact sports should be prohibited.

  13. LITERATURE SURVEY ON CEMENTS FOR REMEDIATION OF DEFORMED CASING IN GEOTHERMAL WELLS

    1998-11-01

    Brookhaven National Laboratory was requested to conduct a literature survey for the best available cement to use in the proposed casing patch as part of the Geothermal Drilling Organization (GDO) project on remediation of deformed casings. A total of 50 wells has been identified with deformed production casing in Unocal's portion of The Geysers geothermal field. Reduced internal diameter and casing doglegs result in lost production and the possible need for abandonment. The cause of the deformations is believed to be formation movement along fault planes and/or along weaker layers or interfaces between high impedance contrast media. Apparently, it is unclear whether shear or axial compression is the dominant failure mechanism. A procedure to address the casing deformation and avoid abandonment of these wells has been developed as described in the Geysers Deformed Casing Remediation Proposal. The proposed remediation procedure involves isolation of the zone of interest with an inflatable packer, milling the deformed casing and cementing a 7 inch diameter liner to extend approximately 100 ft above and 100 ft below the milled zone. During the milling operation it is possible that the original cement and surrounding formation may slough away. In order to specify a suitable cement formulation for the casing patch it is first necessary to identify and understand the deformation mechanism/s operating in The Geysers field. Subsequently, the required cement mechanical properties to withstand further deformation of the repaired system must be defined. From this information it can be determined whether available cement formulations meet these requirements. In addition to The Geysers, other geothermal fields are at possible risk of casing deformation due to subsidence, seismic activity, lateral and vertical formation movement or other processes. Therefore, the proposed remediation procedure may have applications in other fields. The literature survey focused on published

  14. Measurement of thermal conductivity and diffusivity in situ: Literature survey and theoretical modelling of measurements

    1999-01-01

    In situ measurements of thermal conductivity and diffusivity of bedrock were investigated with the aid of a literature survey and theoretical simulations of a measurement system. According to the surveyed literature, in situ methods can be divided into `active` drill hole methods, and `passive` indirect methods utilizing other drill hole measurements together with cutting samples and petrophysical relationships. The most common active drill hole method is a cylindrical heat producing probe whose temperature is registered as a function of time. The temperature response can be calculated and interpreted with the aid of analytical solutions of the cylindrical heat conduction equation, particularly the solution for an infinite perfectly conducting cylindrical probe in a homogeneous medium, and the solution for a line source of heat in a medium. Using both forward and inverse modellings, a theoretical measurement system was analysed with an aim at finding the basic parameters for construction of a practical measurement system. The results indicate that thermal conductivity can be relatively well estimated with borehole measurements, whereas thermal diffusivity is much more sensitive to various disturbing factors, such as thermal contact resistance and variations in probe parameters. In addition, the three-dimensional conduction effects were investigated to find out the magnitude of axial `leak` of heat in long-duration experiments. The radius of influence of a drill hole measurement is mainly dependent on the duration of the experiment. Assuming typical conductivity and diffusivity values of crystalline rocks, the measurement yields information within less than a metre from the drill hole, when the experiment lasts about 24 hours. We propose the following factors to be taken as basic parameters in the construction of a practical measurement system: the probe length 1.5-2 m, heating power 5-20 Wm{sup -1}, temperature recording with 5-7 sensors placed along the probe, and

    Full Text Available Isolated abdominal wall actinomycosis in the presence of an intrauterine contraceptive device (IUCD is extremely rare and only six such cases have been reported in the literature. We report a case where clinical and radiological examinations revealed a pseudotumor within the anterior abdominal wall. After being lost to follow-up, the patient presented two years later with the enlargement of the mass. The mass including the affected anterior abdominal wall was completely excised. The diagnosis of actinomycosis was established postoperatively by histopathological examination. Further questioning concerning her gynecological history revealed long-term use of the same IUCD. Surgical excision of the actinomycotic pseudotumour and removal of the IUCD followed by antibiotic therapy resulted in the full recovery of the patient.

  16. A Synthesis of Relevant Literature on the Development of Emotional Competence: Implications for Design of Augmentative and Alternative Communication Systems.

    Emotional competence refers to the ability to identify, respond to, and manage one's own and others' emotions. Emotional competence is critical to many functional outcomes, including making and maintaining friends, academic success, and community integration. There appears to be a link between the development of language and the development of emotional competence in children who use speech. Little information is available about these issues in children who rely on augmentative and alternative communication (AAC). In this article, we consider how AAC systems can be designed to support communication about emotions and the development of emotional competence. Because limited research exists on communication about emotions in a context of aided AAC, theory and research from other fields (e.g., psychology, linguistics, child development) is reviewed to identify key features of emotional competence and their possible implications for AAC design and intervention. The reviewed literature indicated that the research and clinical attention to emotional competence in children with disabilities is encouraging. However, the ideas have not been considered specifically in the context of aided AAC. On the basis of the reviewed literature, we offer practical suggestions for system design and AAC use for communication about emotions with children who have significant disabilities. Three key elements of discussing emotions (i.e., emotion name, reason, and solution) are suggested for inclusion in order to provide these children with opportunities for a full range of discussion about emotions. We argue that supporting communication about emotions is as important for children who use AAC as it is for children who are learning speech. This article offers a means to integrate information from other fields for the purpose of enriching AAC supports.

    The Structural Classification of Proteins (SCOP) and Class, Architecture, Topology, Homology (CATH) databases have been valuable resources for protein structure classification for over 20 years. Development of SCOP (version 1) concluded in June 2009 with SCOP 1.75. The SCOPe (SCOP-extended) database offers continued development of the classic SCOP hierarchy, adding over 33,000 structures. We have attempted to assess the impact of these two decade old resources and guide future development. To this end, we surveyed recent articles to learn how structure classification data are used. Of 571 articles published in 2012-2013 that cite SCOP, 439 actually use data from the resource. We found that the type of use was fairly evenly distributed among four top categories: A) study protein structure or evolution (27% of articles), B) train and/or benchmark algorithms (28% of articles), C) augment non-SCOP datasets with SCOP classification (21% of articles), and D) examine the classification of one protein/a small set of proteins (22% of articles). Most articles described computational research, although 11% described purely experimental research, and a further 9% included both. We examined how CATH and SCOP were used in 158 articles that cited both databases: while some studies used only one dataset, the majority used data from both resources. Protein structure classification remains highly relevant for a diverse range of problems and settings.

    While numerous authors acknowledge the challenge of teaching simultaneously to medical students, interns, and residents, few offer specific advice on how to meet that challenge, and none have studied which techniques are most effective. The purpose of this study was to determine whether multilevel teaching is challenging for attendings, whether trainees feel that teaching on rounds is appropriate to their level, and to define multilevel teaching techniques. We surveyed attendings and trainees on the internal medicine services at two academic medical centers. Attendings were divided about whether teaching to multiple levels posed a challenge. Trainees reported that the teaching they received was usually appropriate to their level of training. The most effective techniques for multilevel teaching were Broadening (asking "what if" questions), Targeting (directing questions at specific team members), and Novelty (teaching newly published information), while the least effective were techniques that taught advanced material unfamiliar to most or all of the team. A systematic literature review yielded no studies that focused on multilevel teaching techniques. This article is the first to define and evaluate specific techniques for multilevel instruction in a medical setting and identifies certain techniques as more effective at engaging multiple levels of learners simultaneously.

    This paper presents the outcomes of a literature survey of reports on the use of ultrasound methods in the characterization of radioactive wastes. This research is motivated by the necessity to characterize radioactive wastes constituted of ion exchange resins and activated charcoal beds generated at the nuclear research reactor IEA-R1 and that are stored in twenty one 200 L-drum sat the Waste Management Department. These two waste types come from the water polishing system of the nuclear reactor where they are used to remove impurities as fission and activation products from the water. After same time in the water treatment system, these two adsorbents are unable to keep the water quality and are then replaced becoming radioactive waste. Previous work determined the concentration of radio isotopes in dried samples of the adsorbents. As the water content varies largely among different drums, it is necessary to determine the water content of each individual drum for the total activity to be calculated. Ultrasound imaging was thought as an appropriate tool as a characterization method. The different acoustic impedances of liquids and solid salter the propagation of the sound wave sand can disclose the content of the waste packages. (author)

    Retrograde ureteroscopy (URS) has become a common procedure for the management of urinary stones. Although its efficacy and safety are well known, the literature about major complications is still poor. This study highlighted some cases of life-threatening complications after semirigid ureteroscopy (s-URS) or flexible ureteroscopy (f-URS). We enrolled experienced endourologists (more than 75 cases/year in the last 3 years) and we performed a survey asking to review their series and report the cases encumbered by major complications (Clavien-Dindo IIIb-IV grade). Eleven urologists reported on 12 major complications (4 after s-URS, 8 after f-URS). Eight patients developed a kidney injury, 1 an arteriovenous fistula, 2 a ureter avulsion and 1 acute sepsis. Six patients underwent open nephrectomy, two surgical repair, one open pyeloplasty, one coil artery embolization and two superselective artery embolization. Guidelines and clinical practice give useful recommendations about intraoperative safety and prevention of life-threatening events. The careful postoperative observation and the surgical active treatment of this complications play a key role in reducing morbidity, kidney loss and mortality. This study encourages a strict and active care of patients, supports a routine reporting of complications, and highlights the need for systematic use of standardized classification systems.

  2. Metal-Organic Frameworks: Literature Survey and Recommendation of Potential Sorbent Materials

    2010-04-29

    Metal-organic frameworks (MOFs) are a special type of porous material with a number of unique properties, including exceptionally high surface areas, large internal pore volumes (void space) and tunable pore sizes. These materials are prepared through the assembly of molecular building blocks into ordered three-dimensional structures. The bulk properties of the MOF are determined by the nature of the building blocks and, as such, these materials can be designed with special characteristics that cannot be realized in other sorbent materials, like activated carbons. For example, MOFs can be constructed with binding sites or pockets that can exhibit selectivity for specific analytes. Alternatively, the framework can be engineered to undergo reversible dimensional changes (or 'breathing') upon interaction with an analyte, effectively trapping the molecule of interest in the lattice structure. In this report, we have surveyed the 4000 different MOF structures reported in the open literature and provided recommendations for specific MOF materials that should be investigated as sorbents for this project.

    To summarize and then assess with a pilot study the use of published best practice recommendations for priority setting during management of multiple healthcare research projects, in a resource-constrained environment. Medical, economic, business, and operations literature was reviewed to summarize and develop a survey to assess best practices for managing multiple projects. Fifteen senior healthcare research project managers, directors, and faculty at an urban academic institution were surveyed to determine most commonly used priority rules, ranking of rules, characteristics of their projects, and availability of resources. Survey results were compared to literature recommendations to determine use of best practices. Seven priority-setting rules were identified for managing multiple projects. Recommendations on assigning priorities by project characteristics are presented. In the pilot study, a large majority of survey respondents follow best practice recommendations identified in the research literature. However, priority rules such as Most Total Successors (MTS) and Resource Scheduling Method (RSM) were used "very often" by half of the respondents when better performing priority rules were available. Through experience, project managers learn to manage multiple projects under resource constraints. Best practice literature can assist project managers in priority setting by recommending the most appropriate priority given resource constraints and project characteristics. There is room for improvement in managing multiple projects.

    National and subnational level surveys are important for monitoring disease burden, prioritizing resource allocation, and evaluating public health policies. As mobile phone access and ownership become more common globally, mobile phone surveys (MPSs) offer an opportunity to supplement traditional public health household surveys. The objective of this study was to systematically review the current landscape of MPSs to collect population-level estimates in low- and middle-income countries (LMICs). Primary and gray literature from 7 online databases were systematically searched for studies that deployed MPSs to collect population-level estimates. Titles and abstracts were screened on primary inclusion and exclusion criteria by two research assistants. Articles that met primary screening requirements were read in full and screened for secondary eligibility criteria. Articles included in review were grouped into the following three categories by their survey modality: (1) interactive voice response (IVR), (2) short message service (SMS), and (3) human operator or computer-assisted telephone interviews (CATI). Data were abstracted by two research assistants. The conduct and reporting of the review conformed to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 6625 articles were identified through the literature review. Overall, 11 articles were identified that contained 19 MPS (CATI, IVR, or SMS) surveys to collect population-level estimates across a range of topics. MPSs were used in Latin America (n=8), the Middle East (n=1), South Asia (n=2), and sub-Saharan Africa (n=8). Nine articles presented results for 10 CATI surveys (10/19, 53%). Two articles discussed the findings of 6 IVR surveys (6/19, 32%). Three SMS surveys were identified from 2 articles (3/19, 16%). Approximately 63% (12/19) of MPS were delivered to mobile phone numbers collected from previously administered household surveys. The majority of MPS (11

    Urban trees are a dominant natural element in cities; they provide important ecosystem services to urban citizens and help urban areas adapt to climate change. Many rationales have been proposed to provide a purpose for urban forest management, some of which have been ineffective in addressing important ecological and social management themes. Among these rationales we find a values-based perspective, which sees management as a process where the desires of urban dwellers are met. Another perspective is climate change adaptation, which sees management as a process where urban forest vulnerability to climate change is reduced and resilience enhanced. Both these rationales have the advantage of complementing, enhancing, and broadening urban forest management objectives. A critical analysis of the literature on public values related to urban forests and climate change adaptation in the context of urban forests is undertaken to discuss what it means to adopt these two issues in urban forest management. The analysis suggests that by seeing urban forest management as a process by which public values are satisfied and urban-forest vulnerabilities to climate change are reduced, we can place issues such as naturalization, adaptive management, and engaging people in management at the centre of urban forest management. Focusing urban forest management on these issues may help ensure the success of programs focused on planting more trees and increasing citizen participation in urban forest management.

    Objectives To investigate predictors of healthcare professionals’ (HCPs) attitudes towards family involvement in safety-relevant behaviours. Design A cross-sectional fractional factorial survey that assessed HCPs’ attitudes towards family involvement in two error scenarios relating to hand hygiene and medication safety. Each survey comprised two randomised vignettes that described the potential error, how the family member communicated with the HCP about the error and how the HCP responded to the family member’s question. Setting 5 teaching hospitals in London, the Midlands and York. HCPs were approached on a range of medical and surgical wards. Participants 160 HCPs (73 doctors; 87 nurses) aged between 21 and 65 years (mean 37) 102 were female. Outcome measures HCP approval of family member’s behaviour; HCP reaction to the family member; anticipated effects on the family member–HCP relationship; HCP support for being questioned about hand hygiene/medication; affective rating responses. Results HCPs supported family member's intervening (88%) but only 41% agreed this would have positive effects on the family member/HCP relationship. Across vignettes and error scenarios the strongest predictors of attitudes were how the HCP (in the scenario) responded to the family member and whether an error actually occurred. Doctors (vs nurses) provided systematically more positive affective ratings to the vignettes. Conclusions Important predictors of HCPs’ attitudes towards family members’ involvement in patient safety have been highlighted. In particular, a discouraging response from HCP’s decreased support for family members being involved and had strong perceived negative effects on the family member/HCP relationship. PMID:25186154

    To summarize recent research on unintended consequences associated with implementation and use of health information technology (health IT). Included in the review are original empirical investigations published in English between 2014 and 2015 that reported unintended effects introduced by adoption of digital interventions. Our analysis focuses on the trends of this steam of research, areas in which unintended consequences have continued to be reported, and common themes that emerge from the findings of these studies. Most of the papers reviewed were retrieved by searching three literature databases: MEDLINE, Embase, and CINAHL. Two rounds of searches were performed: the first round used more restrictive search terms specific to unintended consequences; the second round lifted the restrictions to include more generic health IT evaluation studies. Each paper was independently screened by at least two authors; differences were resolved through consensus development. The literature search identified 1,538 papers that were potentially relevant; 34 were deemed meeting our inclusion criteria after screening. Studies described in these 34 papers took place in a wide variety of care areas from emergency departments to ophthalmology clinics. Some papers reflected several previously unreported unintended consequences, such as staff attrition and patients' withholding of information due to privacy and security concerns. A majority of these studies (71%) were quantitative investigations based on analysis of objectively recorded data. Several of them employed longitudinal or time series designs to distinguish between unintended consequences that had only transient impact, versus those that had persisting impact. Most of these unintended consequences resulted in adverse outcomes, even though instances of beneficial impact were also noted. While care areas covered were heterogeneous, over half of the studies were conducted at academic medical centers or teaching hospitals

    Full Text Available Individual skin health attitudes are influenced by various factors, including public education campaigns, mass media, family, and friends. Evidence-based, educative information materials assist communication and decision-making in doctor-patient interactions. The present study aims at assessing the prevailing use of skin health information material and sources and their impact on skin health knowledge, motives to tan, and sun protection. We conducted a questionnaire survey among a representative sample of Austrian residents. Print media and television were perceived as the two most relevant sources for skin health information, whereas the source physician was ranked third. Picking the information source physician increased participants’ skin health knowledge (p = 0.025 and sun-protective behavior (p < 0.001. The study results highlight the demand for targeted health messages to attain lifestyle changes towards photo-protective habits. Providing resources that encourage pro-active counseling in every-day doctor-patient communication could increase skin health knowledge and sun-protective behavior, and thus, curb the rise in skin cancer incidence rates.

    The value of a systematic review or meta-analysis depends upon the care with which it is designed and conducted. A major factor in this is the literature search that identifies the articles to be reviewed. Careful selection of bibliographic databases and the use of well-designed search strategies based on the controlled vocabularies contained in published thesauri are essential to ensure retrieval of all relevant articles. This commentary offers suggestions for identifying the literature to be searched, designing a suitable search strategy, using a controlled vocabulary, and describing the bibliographic methodology underlying a systematic review or meta-analysis.

  18. Can the Future EnMAP Mission Contribute to Urban Applications? A Literature Survey

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available With urban populations and their footprints growing globally, the need to assess the dynamics of the urban environment increases. Remote sensing is one approach that can analyze these developments quantitatively with respect to spatially and temporally large scale changes. With the 2015 launch of the spaceborne EnMAP mission, a new hyperspectral sensor with high signal-to-noise ratio at medium spatial resolution, and a 21 day global revisit capability will become available. This paper presents the results of a literature survey on existing applications and image analysis techniques in the context of urban remote sensing in order to identify and outline potential contributions of the future EnMAP mission. Regarding urban applications, four frequently addressed topics have been identified: urban development and planning, urban growth assessment, risk and vulnerability assessment and urban climate. The requirements of four application fields and associated image processing techniques used to retrieve desired parameters and create geo-information products have been reviewed. As a result, we identified promising research directions enabling the use of EnMAP for urban studies. First and foremost, research is required to analyze the spectral information content of an EnMAP pixel used to support material-based land cover mapping approaches. This information can subsequently be used to improve urban indicators, such as imperviousness. Second, we identified the global monitoring of urban areas as a promising field of investigation taking advantage of EnMAP’s spatial coverage and revisit capability. However, owing to the limitations of EnMAPs spatial resolution for urban applications, research should also focus on hyperspectral resolution enhancement to enable retrieving material information on sub-pixel level.

    The need consider the risk impact in case of multi-unit in a single site increased after the accident at Fukushima Daiichi in March 2011. This means that we have to consider the single-unit initiators impacting the other units and the simultaneous accidents of the multi-unit on the same site. Particularly, this kind of technical concern is serious in case of the Republic of Korea where multi-units had to be located in high-density population area due to geographical features. The Nuclear Safety and Security Commission (NSSC) in the Republic of Korea has been trying to identify the state of the art of international and domestic regulations and techniques on multi-unit risk assessment and planning the road map for the safety researches. However, we have to say that finding a common accepted methodology along with safety criteria for multi-unit PSA was not an easy task up to now. This paper summarizes and analyzes related international and domestic journals' papers, conferences' papers and reports about the multi-unit PSA classifying categories with themes to understand the technical tendency of multi-unit PSA. In addition, some insights that were obtained from this classification have been arranged too. This paper investigated the technical trend of the multi-unit PSA as collecting of the international and domestic journals' papers, conferences papers and reports, and analyzing them. Upon the literature survey, a few statistics, technical issues, and insights were summarized. Both of the fundamental and practical researches need to find a globally accepted methodology to calculate and determine quantitative objectives for a multi-unit PSA. We want to expect that this paper can be shared to understand the current status of multi-unit PSA.

  20. Caesium-137 soil sampling and inventory variability in reference locations: A literature survey

    Sutherland, Ross A.

    1996-01-01

    Soil sampling design, the number of samples collected and the lateral variation of caesium-137 (137Cs) in uneroded reference locations were extracted from previously published work. The focus was on published work which used 137Cs reference inventory (Bq m-2) for qualitative or quantitative estimation of sediment redistribution (SRD) within the landscape. The objective of this study was to address one of the methodological concerns facing the 137Cs technique - that is, the lack of a rigorous statistical treatment of reference locations. The limited attention paid to the reference location is not justified as true estimates of SRD are based on the assumption of an unbiased, independent, random probability sample estimate, commonly the arithmetic mean. Results from the literature survey indicated that only 11% of the reference locations sampled for 137Cs expressly stated that a probability sampling design was used (transect or systematic-aligned grid). The remaining locations were generally sampled using a non-probability based design, more commonly known as haphazard sampling. Of the 75 reference study areas identified only 40 provided enough information to determine the dispersion around the mean, and from this the coefficient of variation (CV) was calculated for all available data. The median CV was 19·3%, with 95% confidence limits of 13·0-23.4%, indicating that approximately 11 random, independent samples would generally be necessary to adequately quantify the reference 137Cs area activity with an allowable error of 10% at 90% confidence. Further analysis indicated that only one-third of the studies sampled a sufficient number of 137Cs reference locations. This value would actually be lower as sampling frameworks were based on non-probability sampling procedures. For 137Cs reference locations it is recommended that a probability sampling design be utilized, preferably the systematic-aligned grid method, and as a minimum first-order estimate about 11 samples

  2. Attrition in the Austrian Generations and Gender Survey: Is there a bias by fertility-relevant aspects?

    Directory of Open Access Journals (Sweden)

    Isabella Buber-Ennser

    2014-08-01

    Full Text Available Background: In longitudinal research the loss of sample members between waves is a possible source of bias. It is therefore crucial to analyse attrition. Objective: This paper analyses attrition in a longitudinal study on family and fertility, by distinguishing between attrition due to non-contact and attrition due to non-cooperation. Methods: Based on the first two waves of the Austrian Generations and Gender Survey, the two components of attrition are studied separately by using bivariate as well as multivariate methods. Moreover, overall dropout - the combination of both components - isanalysed. Apart from various socio-economic characteristics and data collection information, the study focuses on fertility-relevant variables such as fecundity, fertility intentions, sexual orientation, and traditional attitudes. Results: Fecundity, fertility intentions, and homosexual relationships are associated with higher attrition due to non-cooperation in bivariate analyses, but have no explanatory power inthe multivariate model. Pregnancy and traditional attitudes towards marriage are associated with significantly lower attrition due to non-cooperation in the multivariate context. Overall dropout is significantly lower only among persons with traditionalattitudes towards marriage, although small in size and statistical significance. Moreover, various individual and regional characteristics are significantly associated with dropout, with differences between attrition due to non-contact and attrition due to non-cooperation. Conclusions: Detailed insights into attrition are not only important when using longitudinal data and interpreting results, but also for the design of future data collections. The Austrian GGS panel has a relatively low dropout (22Š and is affected by a small bias towards familyoriented persons as well as less-educated respondents and persons with migrationbackgrounds, but the data can be used without concern about selectivity.

    The main objective with this literature survey is to elucidate the state of the art of internal erosion in embankment dams in order to be able to formulate a research program for numerical modelling of internal erosion in a physically sound manner. Since these processes normally are localised to specific zones in a dam, the ordinary continuum approach frequently utilised in soil modelling will not, by itself, be successful. The plan of the research group is therefore to treat internal erosion...

    Pathology as a basic science discipline traditionally is a component of the preclinical medical school curriculum. While there have been regional and nationwide surveys reporting on the curricular organization and instructional formats of preclinical pathology instruction, the extent of required pathology integration into the clinical medical school curriculum, particularly as it relates to practical issues of patient management, has not been studied. A survey soliciting information about required pathology programs in the clinical years was distributed to the members of the Undergraduate Medical Educators Section of the Association of Pathology Chairs (APC). A literature search of such programs was also performed. Thirty-seven respondents representing 30 medical schools (21% of the 140 Liaison Committee on Medical Education-accredited medical schools in the APC) described a total of 16 required pathology programs in the clinical years. An additional 10 programs were identified in the literature. Advantages of required pathology activities in the clinical years include educating medical students in effective utilization of anatomic and clinical pathology for patient care and exposing them to the practice of pathology. Reported challenges have been competition for curricular time in the clinical years, attitudinal resistance by clerkship directors, failure to recognize pathology as a clinical discipline, and insufficient number of faculty in pathology departments. By survey sample and literature review, there has been relatively little progress in the integration of required pathology exposure into the clinical years. Development of practice-related pathology competencies may facilitate introduction of such curricular programs in the future.

    Background Spontaneous rupture of the spleen is an uncommon dramatic abdominal emergency that requires immediate diagnosis and prompt surgical treatment to ensure the patients survival. Infections have been cited in most cases involving splenic rupture but are rare in hematological malignancies despite frequent involvement of the spleen. Methods and Materials We present a case of a splenic rupture caused by infiltration of B-cell lymphoma. A 43 year old gentleman presented with a 1 day h/o left upper quadrant pain; nausea and vomiting for 2 days with associated dizziness and anorexia. The CT showed abnormal spleen 20 × 11 cm with free fluid in the abdomen and enlarged retroperitoneal LNs. The patient underwent a splenectomy after initial resuscitation and the operative finding was that of a massively enlarged spleen with areas of tumor extruding through the splenic capsule. Result and conclusion Although the spleen is often involved in hematological malignancies, splenic rupture is an infrequent occurrence. In a recent literature review 136 cases were of splenic rupture secondary to hematological malignancy were identified. Acute leukemia and non Hodgkin lymphoma were the frequent causes followed by chronic myelogeneous leukemia. Male sex, adulthood, severe splenomegaly and cytoreductive chemotherapy were factors more often associated with splenic rupture. Emergency splenectomy remains the cornerstone treatment for splenic rupture. We present a case report of a "spontaneous splenic rupture" and discuss the presentation, etiology and treatment options along with discussion of relevant literature PMID:17129392

    Four radionuclides have been identified as being sufficiently volatile in the reprocessing of nuclear fuel that their gaseous release needs to be controlled to meet regulatory requirements (Jubin et al. 2011, 2012). These radionuclides are 3H, 14C, 85Kr, and 129I. Of these, 129I has the longest half-life and potentially high biological impact. Accordingly, control of the release of 129I is most critical with respect to the regulations for the release of radioactive material in stack emissions. It is estimated that current EPA regulations (EPA 2010) would require any reprocessing plant in the United States to limit 129I release to less than 0.05 Ci/MTIHM for a typical fuel burnup of 55 gigawatt days per metric tonne (GWd/t) (Jubin 2011). The study of inorganic iodide in off-gas systems has been almost exclusively limited to I2 and the focus of organic iodide studies has been CH3I. In this document, we provide the results of an examination of publically available literature that is relevant to the presence and sources of both inorganic and organic iodine-bearing species in reprocessing plants. We especially focus on those that have the potential to be poorly sequestered with traditional capture methodologies. Based on the results of the literature survey and some limited thermodynamic modeling, the inorganic iodine species hypoiodous acid (HOI) and iodine monochloride (ICl) were identified as potentially low-sorbing iodine species that could present in off-gas systems. Organic species of interest included both short chain alkyl iodides such as methyl iodide (CH3I) and longer alkyl iodides up to iodododecane (C10H21I). It was found that fuel dissolution may provide conditions conducive to HOI formation and has been shown to result in volatile long-chain alkyl iodides, though these may not volatilize until later in the reprocessing sequence. Solvent extraction processes were found to be significant sources of various organic iodine-bearing species; formation of these

    Full Text Available The aim of this paper is to define a relevant market in the passenger transportation industry for the route between Prague and Most. A rising number of bus companies operating on this particular market suggests competition pressures. On the basis of European Commission legislation and its common practice we apply a demand-side substitution analysis in the form of the so called SSNIP test. Data for the empirical analysis were collected by means of a customer survey, which captured reactions to a 10% increase in the price of purchased tickets. The survey outcomes were then used to calculate an own price elasticity of demand and to carry out a critical loss analysis in order to define the relevant market.

  15. A Survey of Bioinformatics Database and Software Usage through Mining the Literature.

    Directory of Open Access Journals (Sweden)

    Geraint Duck

    Full Text Available Computer-based resources are central to much, if not most, biological and medical research. However, while there is an ever expanding choice of bioinformatics resources to use, described within the biomedical literature, little work to date has provided an evaluation of the full range of availability or levels of usage of database and software resources. Here we use text mining to process the PubMed Central full-text corpus, identifying mentions of databases or software within the scientific literature. We provide an audit of the resources contained within the biomedical literature, and a comparison of their relative usage, both over time and between the sub-disciplines of bioinformatics, biology and medicine. We find that trends in resource usage differs between these domains. The bioinformatics literature emphasises novel resource development, while database and software usage within biology and medicine is more stable and conservative. Many resources are only mentioned in the bioinformatics literature, with a relatively small number making it out into general biology, and fewer still into the medical literature. In addition, many resources are seeing a steady decline in their usage (e.g., BLAST, SWISS-PROT, though some are instead seeing rapid growth (e.g., the GO, R. We find a striking imbalance in resource usage with the top 5% of resource names (133 names accounting for 47% of total usage, and over 70% of resources extracted being only mentioned once each. While these results highlight the dynamic and creative nature of bioinformatics research they raise questions about software reuse, choice and the sharing of bioinformatics practice. Is it acceptable that so many resources are apparently never reused? Finally, our work is a step towards automated extraction of scientific method from text. We make the dataset generated by our study available under the CC0 license here: http://dx.doi.org/10.6084/m9.figshare.1281371.

    Advances in the understanding of tumor biology have led to the development of targeted therapies as monoclonal antibodies (MoAbs) in clinical oncology. Among their suggested mechanisms of action monoclonal antibodies (IgG1) selectively directed against tumor membrane receptors mediate of antibody-dependent cellular cytotoxicity (ADCC) by triggering Fc-γRIII on natural killer (NK) cells. This study reviews the clinical context of ADCC measurement with a particular focus on EGFR targeting and describes an ex vivo ADCC method applied to MoAbs (cetuximab and panitumumab), against epidermal growth factor receptor (EGFR). The test performance was evaluated on different target cells lines (CAL166, A431, HNO91, CAL27), with different effector cells (peripheral blood mononuclear cells or natural killers -NK-) and in various experimental conditions, in order to establish a truly clinically applicable method. Using the experience available in the published literature, we optimized all variables involved in the experimental design: target cells type, numbers and ratio target cells and NK cells (effector cells) per well, time of exposure and repeatability. ADCC measurement may be of clinical relevance in the context of treatment with MoAbs. This study describes a non-radioactive method which has proven satisfactory in terms of sensitivity, reproducibility, feasibility and cost effectiveness for the measurement of ADCC activity mediated by NK with an orientation towards the EGFR target.

    2016-12-01

    This study aimed to identify the anatomical items of the upper extremity and spine that are potentially relevant to the practice of rheumatology. Ten rheumatologists interested in clinical anatomy who published, taught, and/or participated as active members of Clinical Anatomy Interest groups (six seniors, four juniors), participated in a one-round relevance Delphi exercise. An initial, 560-item list that included 45 (8.0 %) general concepts items; 138 (24.8 %) hand items; 100 (17.8 %) forearm and elbow items; 147 (26.2 %) shoulder items; and 130 (23.2 %) head, neck, and spine items was compiled by 5 of the participants. Each item was graded for importance with a Likert scale from 1 (not important) to 5 (very important). Thus, scores could range from 10 (1 × 10) to 50 (5 × 10). An item score of ≥40 was considered most relevant to competent practice as a rheumatologist. Mean item Likert scores ranged from 2.2 ± 0.5 to 4.6 ± 0.7. A total of 115 (20.5 %) of the 560 initial items reached relevance. Broken down by categories, this final relevant item list was composed by 7 (6.1 %) general concepts items; 32 (27.8 %) hand items; 20 (17.4 %) forearm and elbow items; 33 (28.7 %) shoulder items; and 23 (17.6 %) head, neck, and spine items. In this Delphi exercise, a group of practicing academic rheumatologists with an interest in clinical anatomy compiled a list of anatomical items that were deemed important to the practice of rheumatology. We suggest these items be considered curricular priorities when training rheumatology fellows in clinical anatomy skills and in programs of continuing rheumatology education.

    To identify the current management modalities practiced by neurosurgeons in India for chronic subdural hematoma. A questionnaire was prepared for the survey and sent via e-mail to neurosurgeons. It covered the following aspects of managing chronic subdural hematoma: 1) demographic and institutional details; 2) choice of surgical procedure; 3) surgical adjutants such as placing a subdural drain; 4) pre- and postoperative care; and 5) recurrences and management. Responses obtained were entered in a SPSS data sheet and analyzed. Response rate of the survey was 9.3%. The majority of neurosurgeons (75%) preferred to do burr whole drainage for primary chronic subdural hematoma and also for recurrences. Only one third of routinely placed a subdural drain. Considerable practice variations exist for medical and perioperative management. Bedside twist drill drainage, which is effective and less costly than operative room procedures, has not gained popularity in practice. The present survey points towards the importance of making management guidelines for this common neurosurgical entity. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The problem of teaching and learning of Russian language and literature in schools with native (Tatar language of teaching related to the implementation of the principle of dialogue between cultures. The article draws on the results of the survey of graduates of the two high schools of Kazan: School #2 with teaching in Tatar language and school #37 with teaching in Russian-language. The results of the survey are associated with the problems of bilingualism, multiculturalism and bimentality. Graduates from Tatar language gymnasium are bilingual and fluent in Russian and Tatar languages. 97% of graduates of Tatar gymnasium speak, read and write free in their native language and 96% in Russian. Bilingualism acts in this case like one of the manifestations of inter-ethnic interaction, a particular manifestation of biculturalism. In the National School dialogue of cultures passes through a system of parallel study of both Russian and Tatar languages and literatures: the formation of a bicultural, bilingual, bimental personality able to perceive not only the native culture, but also other (Russian culture as the native is taking place.

  12. Effects of soy protein and soybean isoflavones on thyroid function in healthy adults and hypothyroid patients: a review of the relevant literature.

    2006-03-01

    Soy foods are a traditional staple of Asian diets but because of their purported health benefits they have become popular in recent years among non-Asians, especially postmenopausal women. There are many bioactive soybean components that may contribute to the hypothesized health benefits of soy but most attention has focused on the isoflavones, which have both hormonal and nonhormonal properties. However, despite the possible benefits concerns have been expressed that soy may be contraindicated for some subsets of the population. One concern is that soy may adversely affect thyroid function and interfere with the absorption of synthetic thyroid hormone. Thus, the purpose of this review is to evaluate the relevant literature and provide the clinician guidance for advising their patients about the effects of soy on thyroid function. In total, 14 trials (thyroid function was not the primary health outcome in any trial) were identified in which the effects of soy foods or isoflavones on at least one measure of thyroid function was assessed in presumably healthy subjects; eight involved women only, four involved men, and two both men and women. With only one exception, either no effects or only very modest changes were noted in these trials. Thus, collectively the findings provide little evidence that in euthyroid, iodine-replete individuals, soy foods, or isoflavones adversely affect thyroid function. In contrast, some evidence suggests that soy foods, by inhibiting absorption, may increase the dose of thyroid hormone required by hypothyroid patients. However, hypothyroid adults need not avoid soy foods. In addition, there remains a theoretical concern based on in vitro and animal data that in individuals with compromised thyroid function and/or whose iodine intake is marginal soy foods may increase risk of developing clinical hypothyroidism. Therefore, it is important for soy food consumers to make sure their intake of iodine is adequate.

    With increasing medical knowledge and emphasis upon evidence-based medicine, it is essential for practitioners to have optimal literature searching skills. There are limited data regarding the use of online information retrieval (IR) systems by paediatric junior medical officers (JMO). The aims of this questionnaire-based study of a group of JMO were to assess the accessibility, frequency of use and preferences for electronic information resources, and to ascertain their perceived adequacy of training and expertise in online searching. Questionnaires were distributed to 319 JMO at two Australian children's hospitals. A total of 106 questionnaires were returned (33.2% response rate). Twenty-four-hour access to electronic medical databases was available to almost 90% of respondents at work or home. Five or less online searches per month were performed by 53.7% of respondents. Previous formal training in database searching was reported by 72.4% of respondents, but over half felt it had been inadequate. Most JMO (91.5%) acknowledged a need for further training in search skills. In spite of widespread availability of online resources, use of these resources was sub-optimal in this group of trainee doctors. Most respondents reported a need for further training in electronic searching. Continuing targeted education in electronic database searching is required to ensure that future doctors develop skills to ensure optimal use of medical literature.

  14. Good practices for a literature survey are not followed by authors while preparing scientific manuscripts

    2010-01-01

    The number of citations received by authors in scientific journals has become a major parameter to assess individual researchers and the journals themselves through the impact factor. A fair assessment therefore requires that the criteria for selecting references in a given manuscript should be unbiased with respect to the authors or the journals cited. In this paper, we advocate that authors should follow two mandatory principles to select papers (later reflected in the list of references) while studying the literature for a given research: i) consider similarity of content with the topics investigated, lest very related work should be reproduced or ignored; ii) perform a systematic search over the network of citations including seminal or very related papers. We use formalisms of complex networks for two datasets of papers from the arXiv repository to show that neither of these two criteria is fulfilled in practice.

Rationalization of viewpoints combined with the political turmoil of the century, causing immense setbacks within the English literary traditions. One of these setbacks took place within the romance tradition which had been a major mode of writing during the earlier centuries. In this sense, this article analyses reasons of the decline of the romance tradition throughout seventeenth century English literature as well as examining how the genre managed to survive either implicitly or explicitly in several works like Oroonoko by Aphra Behn, pastoral poems by Andrew Marvel and Milton, and in some parts of Milton’s Paradise Lost.

    Brain is a rare site of metastasis in most extracranial pediatric solid tumors. The aim of this study is to investigate the incidence, treatment, prognosis of brain metastasis in extracranial pediatric malignant tumors in a single institution and to review the literature. From September 1989 to December 2002, 1100 children Pediatric Oncology, Oncology Institute, Istanbul University. Patients with parenchymal metastases in the brain were assessed. Sixteen (10 female, 6 male) of 1100 patients (1.45%) with extracranial solid tumors developed brain metastases. The median age of the patients was 10.5 (1-16) years. The diagnosis was sarcomas in 12 patients: 5 osteosarcomas, 4 Ewing's sarcoma family tumors, 1 rhabdomyosarcoma, 1 clear cell sarcoma of the soft tissue, 1 alveolar soft part sarcoma. Two patients had Wilms' tumor and two had germ cell tumors. Four patients (25%) had brain metastasis at diagnosis. Twelve (75%) developed brain metastasis during therapy or relapse at a median duration of 16 (1-70) months from initial diagnosis. All patients had metastases to various sites, mostly lung, at the time the brain metastases were detected. Treatment included surgery, followed by postoperative radiotherapy (RT) and chemotherapy (CT) in 1, S and RT in 1, S in 1, RT and CT in 6, RT in 1, CT in 1 and no treatment in 5. Only one patient with alveolar soft part sarcoma is alive with disease 20 months from diagnosis of brain metastasis. All other patients died at a median time of 2 months (2 days-6 months) from the time of brain metastasis. Children with metastatic cancer who develop headaches or any other neurologic symptom should be investigated for possible brain metastasis. Although, the outcome for these patients is dismal in this series and in the literature; reports of long term survival in a few cases with Wilms' tumor, osteosarcoma and alveolar soft part sarcoma who had isolated brain metastasis, suggest that a subset of patients may benefit from therapy.

    Isothermal titration calorimetry (ITC) is becoming widely accepted as a key instrument in any laboratory in which quantification of biomolecular interactions is a requisite. The method has matured with respect to general acceptance and application development over recent years. The number of publications on ITC has grown exponentially over the last 10 years, reflecting the general utility of the method. Here all the published works of the year 2002 in this area have been surveyed. We review the broad range of systems to which ITC is being directed and classify these into general areas highlighting key publications of interest. This provides an overview of what can be achieved using this method and what developments are likely to occur in the near future.

    2003-01-01

    Tuberculosis has re-emerged as a significant public health threat over the last decade both globally and within Australia. This is thought to be largely due to the HIV epidemic, a growing itinerant population, and immigration. The antibiotic isoniazid remains an integral part of drug therapy. With the numbers of patients receiving isoniazid remaining high, the number of cases of acute poisoning is expected to be significant. This paper presents a series of two cases of isoniazid poisoning presenting to a tertiary referral centre in North Queensland. Isoniazid toxicity produces a triad of coma, metabolic acidosis and seizures. The seizures are often refractory to traditional antiepileptics. A specific antidote is available (pyridoxine [vitamin B6]) and both patients were administered this as part of their treatment. We also surveyed all hospitals in Australia with an accredited adult Emergency Department to assess the availability of pyridoxine.

    When space vehicles are launched, extreme heat, exhaust, and chemicals are produced and these form a very aggressive exposure environment at the launch complex. The facilities in the launch complex are exposed to this aggressive environment. The vehicle exhaust directly impacts the flame deflectors, making these systems very susceptible to high wear and potential failure. A project was formulated to develop or identify new materials or systems such that the wear and/or damage to the flame deflector system, as a result of the severe environmental exposure conditions during launches, can be mitigated. This report provides a survey of potential protective coatings for the refractory concrete lining on the steel base structure on the flame deflectors at Kennedy Space Center (KSC).

    Elucidation of the energetic principles of binding affinity and specificity is a central task in many branches of current sciences: biology, medicine, pharmacology, chemistry, material sciences, etc. In biomedical research, integral approaches combining structural information with in-solution biophysical data have proved to be a powerful way toward understanding the physical basis of vital cellular phenomena. Isothermal titration calorimetry (ITC) is a valuable experimental tool facilitating quantification of the thermodynamic parameters that characterize recognition processes involving biomacromolecules. The method provides access to all relevant thermodynamic information by performing a few experiments. In particular, ITC experiments allow to by-pass tedious and (rarely precise) procedures aimed at determining the changes in enthalpy and entropy upon binding by van't Hoff analysis. Notwithstanding limitations, ITC has now the reputation of being the "gold standard" and ITC data are widely used to validate theoretical predictions of thermodynamic parameters, as well as to benchmark the results of novel binding assays. In this paper, we discuss several publications from 2007 reporting ITC results. The focus is on applications in biologically oriented fields. We do not intend a comprehensive coverage of all newly accumulated information. Rather, we emphasize work which has captured our attention with originality and far-reaching analysis, or else has provided ideas for expanding the potential of the method.

    While recent progress has been achieved in understanding the structure and dynamics of social tagging systems, we know little about the underlying user motivations for tagging, and how they influence resulting folksonomies and tags. This paper addresses three issues related to this question. (1) What distinctions of user motivations are identified by previous research, and in what ways are the motivations of users amenable to quantitative analysis? (2) To what extent does tagging motivation vary across different social tagging systems? (3) How does variability in user motivation influence resulting tags and folksonomies? In this paper, we present measures to detect whether a tagger is primarily motivated by categorizing or describing resources, and apply these measures to datasets from seven different tagging systems. Our results show that (a) users’ motivation for tagging varies not only across, but also within tagging systems, and that (b) tag agreement among users who are motivated by categorizing resources is significantly lower than among users who are motivated by describing resources. Our findings are relevant for (1) the development of tag-based user interfaces, (2) the analysis of tag semantics and (3) the design of search algorithms for social tagging systems. PMID:23471473

    Full Text Available Authors in their works study vibroimpact system dynamic behaviour by numerical parametric continuation technique combined with shooting and Newton-Raphson’s methods. The technique is adapted to two-mass two-degree-of-freedom vibroimpact system under periodic excitation. Impact is simulated by nonlinear contact interaction force based on Hertz’s contact theory. Stability or instability of obtained periodic solutions is determined by monodromy matrix eigenvalues (multipliers based on Floquet’s theory. In the present paper we describe the state of problem of parameter continuation method using for nonlinear tasks solution. Also we give the short survey of numerous contemporary literature in English and Russian about parameter continuation method application for nonlinear problems. This method is applied for vibroimpact problem solving more rarely because of the difficulties connected with repeated impacts.

    1980-09-11

    Ion acoustic turbulence is examined as one mechanism which could contribute to the inhibition of electron thermal transport which has been inferred from many laser-plasma experiments. The behavior of the ion acoustic instability is discussed from the viewpoint of the literature of 2-dimensional particle-in-cell simulations. Simulation techniques, limitations, and reported saturation mechanisms and levels are discussed. A scaling law for the effective collision frequency ..nu..* can be fit to several workers' results to within an order-of-magnitude. The inferred ..nu..* is shown to be 1-2 orders-of-magnitude too small to account for the transport inhibition seen in Nd-laser-produced plasmas. Several differences between the simulation conditions and laser-produced plasma conditions are noted.

    Campylobacter species are common bacterial pathogens associated with human gastroenteritis worldwide. In North America, Europe and Japan, campylobacteriosis is one of the leading food-borne bacterial illnesses and the consumption of poultry meats and/or by-products is suspected a major cause of the illness. In this survey, we summarized the research papers describing Campylobacter contamination of retail poultry meats and by-products in various countries of the world. In most of the countries, a majority of retail poultry meats and by-products were contaminated with Campylobacter spp. C. jejuni was usually the dominant Campylobacter species isolated from retail poultry and C. coli was less frequently isolated, although the ratio of C. coli to C. jejuni was considerably different among the countries. However, in Thailand and South Africa, C. coli was the dominant Campylobacter species isolated from retail poultry. A large portion of retail poultry was contaminated with Campylobacter spp. in the world; therefore, further trials are required for finding proper countermeasures and attention should be paid for the sanitary handling of poultry products.

    Osteopetrosis or Albers-Schonberg disease is a rare hereditary disorder of osteoclast function in which resorption of bone is diminished, resulting in abnormally dense bones. The condition is known to occur in at least four recognizable clinical patterns, each of which is variable. The optimal treatment of fractures and of bone deformity in these patients has not previously been made clear. To determine appropriate orthopedic management of the condition, we conducted a survey of the membership of the Pediatric Orthopedic Society of North America. The combined experience of 57 surgeons who treated 79 patients with osteopetrosis was compiled. Four femoral neck fractures treated by closed reduction and internal fixation had a satisfactory result, but three treated nonoperatively developed varus and required osteotomy. A total of 20 hips was treated for coxa vara by various means, none of which was free of complications. Valgus osteotomy, when used as the primary treatment for coxa vara, was the most consistently satisfactory procedure, whereas in situ pinning failed in two of three hips. Fourteen subtrochanteric fractures and 31 other fractures of the femur were treated. Good results were reported with traction or casting or both in the majority of those fractures. Twenty-nine tibia fractures were treated successfully, the majority by nonoperative means. Upper extremity fractures healed well with closed reduction and casting. Vertebral fractures, spondylolysis, and back pain were most frequently treated without surgery.

    Full Text Available Safety, reliability, efficiency and performance of rotating machinery in all industrial applications are the main concerns. Rotating machines are widely used in various industrial applications. Condition monitoring and fault diagnosis of rotating machinery faults are very important and often complex and labor-intensive. Feature extraction techniques play a vital role for a reliable, effective and efficient feature extraction for the diagnosis of rotating machinery. Therefore, developing effective bearing fault diagnostic method using different fault features at different steps becomes more attractive. Bearings are widely used in medical applications, food processing industries, semi-conductor industries, paper making industries and aircraft components. This paper review has demonstrated that the latest reviews applied to rotating machinery on the available a variety of vibration feature extraction. Generally literature is classified into two main groups: frequency domain, time frequency analysis. However, fault detection and diagnosis of rotating machine vibration signal processing methods to present their own limitations. In practice, most healthy ingredients faulty vibration signal from background noise and mechanical vibration signals are buried. This paper also reviews that how the advanced signal processing methods, empirical mode decomposition and interference cancellation algorithm has been investigated and developed.

    The declining number of physician scientists is an alarming issue. A systematic review of all existing programs described in the literature was performed, so as to highlight which programs may serve as the best models for the training of successful physician scientists. Multiple databases were searched, and 1,294 articles related to physician scientist training were identified. Preference was given to studies that looked at number of confirmed publications and/or research grants as primary outcomes. Thirteen programs were identified in nine studies. Eighty-three percent of Medical Scientist Training Program (MSTP) graduates, 77% of Clinician Investigator Training Program (CI) graduates, and only 16% of Medical Fellows Program graduates entered a career in academics. Seventy-eight percent of MSTP graduates succeeded in obtaining National Institute of Health (NIH) grants, while only 15% of Mayo Clinic National Research Service Award-T32 graduates obtained NIH grants. MSTP physician scientists who graduated in 1990 had 13.5 ± 12.5 publications, while MSTP physician scientists who graduated in 1975 had 51.2 ± 38.3 publications. Additionally, graduates from the Mayo Clinic's MD-PhD Program, the CI Program, and the NSRA Program had 18.2 ± 20.1, 26.5 ± 24.5, and 17.9 ± 26.3 publications, respectively. MSTP is a successful model for the training of physician scientists in the United States, but training at the postgraduate level also shows promising outcomes. An increase in the number of positions available for training at the postgraduate level should be considered.

    This activity was begun with the assembly of information from Parsons' files and from contacts in the development and commercial fields. A further more extensive literature search was carried out using the Energy Data Base and the American Petroleum Institute Data Base. These are part of the DOE/RECON system. Approximately 6000 references and abstracts were obtained from the EDB search. These were reviewed and the especially pertinent documents, approximately 300, were acquired in the form of paper copy or microfiche. A Fuel Properties form was developed for listing information pertinent to gas turbine liquid fuel properties specifications. Fuel properties data for liquid fuels from selected synfuel processes, deemed to be successful candidates for near future commercial plants were tabulated on the forms. The processes selected consisted of H-Coal, SRC-II and Exxon Donor Solvent (EDS) coal liquefaction processes plus Paraho and Tosco shale oil processes. Fuel properties analyses for crude and distillate syncrude process products are contained in Section 2. Analyses representing synthetic fuels given refinery treatments, mostly bench scale hydrotreating, are contained in Section 3. Section 4 discusses gas turbine fuel specifications based on petroleum source fuels as developed by the major gas turbine manufacturers. Section 5 presents the on-site gas turbine fuel treatments applicable to petroleum base fuels impurities content in order to prevent adverse contaminant effects. Section 7 relates the environmental aspects of gas turbine fuel usage and combustion performance. It appears that the near future stationary industrial gas turbine fuel market will require that some of the synthetic fuels be refined to the point that they resemble petroleum based fuels.

    As a new concept that emerged in the middle of 1990's, data mining can help researchers gain both novel and deep insights and can facilitate unprecedented understanding of large biomedical datasets. Data mining can uncover new biomedical and healthcare knowledge for clinical and administrative decision making as well as generate scientific hypotheses from large experimental data, clinical databases, and/or biomedical literature. This review first introduces data mining in general (e.g., the background, definition, and process of data mining), discusses the major differences between statistics and data mining and then speaks to the uniqueness of data mining in the biomedical and healthcare fields. A brief summarization of various data mining algorithms used for classification, clustering, and association as well as their respective advantages and drawbacks is also presented. Suggested guidelines on how to use data mining algorithms in each area of classification, clustering, and association are offered along with three examples of how data mining has been used in the healthcare industry. Given the successful application of data mining by health related organizations that has helped to predict health insurance fraud and under-diagnosed patients, and identify and classify at-risk people in terms of health with the goal of reducing healthcare cost, we introduce how data mining technologies (in each area of classification, clustering, and association) have been used for a multitude of purposes, including research in the biomedical and healthcare fields. A discussion of the technologies available to enable the prediction of healthcare costs (including length of hospital stay), disease diagnosis and prognosis, and the discovery of hidden biomedical and healthcare patterns from related databases is offered along with a discussion of the use of data mining to discover such relationships as those between health conditions and a disease, relationships among diseases, and

    The International Agency for Research on Cancer (IARC) currently lists 44 individual chemical agents, 12 groups or mixtures of chemicals and 13 exposure circumstances as "Group 1 human carcinogens". A comprehensive search of the published literature revealed that nine of the 44 chemical agents classified as "Group I carcinogens" by IARC have been reported to occur in mainstream cigarette smoke. The other 35 have never been reported to occur in cigarette smoke. The nine agents reported are benzene, cadmium, arsenic, nickel, chromium, 2-naphthyl-amine, vinyl chloride, 4-aminobiphenyl and beryllium. The reported yields of each of these nine agents in mainstream smoke varies widely. The range of yields reported for a given compound is influenced by the type of cigarette tested and when the analysis was conducted. In micrograms/cigarette, the ranges that have been reported for each of the nine compounds are: benzene (0.05-104), cadmium (0-6.67), arsenic (0-1.4), nickel (0-0.51), chromium (0.0002-0.5), 2-naphthylamine (0.0002-0.022), vinyl chloride (0.0013-0.0158), 4-aminobiphenyl (0.00019-0.005) and beryllium (0-0.0005). Although some of the variation in reported yields may be due to differences in analytical methodology, several correlations between the yield of a particular chemical in mainstream smoke and certain cigarette characteristics were observed. For example, charcoal filtration was associated with reduced vinyl chloride, and the concentration of sodium nitrate in the tobacco was positively correlated with the mainstream yield of both 2-naphthylamine and 4-aminobiphenyl. Benzene yield in mainstream cigarette smoke was correlated with the amount of tobacco burned and with the 'tar' level. Agronomic factors such as production practices and soil characteristics, and environmental conditions such as rainfall, reportedly influence the accumulation of metals, for example, cadmium, beryllium, chromium, nickel and arsenic, in the leaf.

    Full Text Available This study focuses on the feasibility of applying alternative futures and scenario analysis in landscape planning during climate change to provide a wider perspective and deeper understanding of this approach for better use and more effective application in the future. The study consists of a literature review and an analysis of recent applied projects carried out worldwide. In addition, an electronic survey was conducted from March to September 2014 to examine viewpoints on the use and application of this approach with reference to climate-change impacts. The survey participants were a group of highly experienced researchers from eighteen countries involved in at least one applied project since 2000 relating to this topic. After analysis of more than forty applied projects, the survey results were incorporated into the analysis to create a comprehensive picture regarding the potentials and limitations of alternative futures and scenario analysis in landscape planning with particular attention to climate change. The findings show that this method is one of the most effective decision-making approaches for adopting landscape policies where landscapes change rapidly under the pressure of urbanisation and climate change. Nevertheless, there is a gap between the advances offered by the approach in various dimensions and the complexity of patterns, uncertainties and upheavals in landscapes due to climate-change impacts in the urbanising world. The research indicates that the approach opens up a great opportunity for decision-makers to expand their perspective and adopt appropriate landscape policies before reaching a point of no return from the sustainability point of view. Meanwhile, there are challenges and barriers in the application of alternative futures and scenario analysis for envisioning the landscapes influenced by climate change and urbanisation that should be pushed back. Although informative, this research raises new questions about this

    Aim: To identify current practices within paediatric radiology in the UK with regard to the use of prophylactic medication, prior to administering intravenous (IV) radiocontrast medium (RCM). In addition, the pre-injection risk management strategies of the departments questioned was to be evaluated, and using consensus opinion, a protocol for managing patients identified as being at high risk for an adverse reaction to RCM was to be outlined. Materials and methods: An online survey of paediatric radiology consultants representing all geographic regions of the UK was carried out. The questions asked included an assessment of the risk factors for adverse reactions to RCM, and how such reactions are anticipated and managed. The questionnaire asked about the perceived indications for, and the use of prophylactic medication prior to RCM administration. Results: A response rate of 51% was achieved. The majority of respondents felt that a history of previous RCM reaction was an indication to administer prophylactic drugs prior to a further dose of RCM. No other risk factor was believed to require prophylactic medication. Conclusion: Using information obtained from the survey, a literature search was performed to assess the evidence available in support of each practice. A protocol was devised to identify children at risk of an adverse reaction to RCM, and guide the use of prophylactic medication in this group of patients. The survey highlighted considerable variability in the risk-assessment and management practices within paediatric radiology in the UK. The derived protocol may guide radiologists' management of children at risk for an RCM reaction.

    Full Text Available Abstract Background JAK2V617F is found in the majority of patients with Ph- myeloproliferative neoplasms (MPNs and has become a valuable marker for diagnosis of MPNs. However, it has also been found in many other hematological diseases, and some studies even detected the presence of JAK2V617F in normal blood samples. This casts doubt on the primary role of JAK2V617F in the pathogenesis of MPNs and its diagnostic value. Methods In the present study, we analyzed JAK2V617F positivity with 232 normal blood samples and 2663 patient blood, bone marrow, and amniotic fluid specimens obtained from a clinical genetics laboratory by using a simple DNA extraction method and a sensitive nested allele-specific PCR strategy. Results We found JAK2V617F present in the majority (78% of MPN patients and in a small fraction (1.8-8.7% of patients with other specific hematological diseases but not at all in normal healthy donors or patients with non-hematological diseases. We also revealed associations of JAK2V617F with novel as well as known chromosomal abnormalities. Conclusions Our study suggests that JAK2V617F positivity is associated with specific hematological malignancies and is an excellent diagnostic marker for MPNs. The data also indicate that the nested allele-specific PCR method provides clinically relevant information and should be conducted for all cases suspected of having MPNs as well as for other related diseases.

    This study was conducted to evaluate the current implementation of outcome measures in routine clinical haemophilia practice and to explore and appreciate the perception of the relevance of such measures by treaters. A survey was completed by 19 of the 26 physicians involved in the European Haemophilia Therapy Strategy Board (EHTSB). Employing an extensive inventory of outcome measures used in patients with haemophilia, information was collected about the frequency of data collection and the subjective appreciation of their importance during clinic review. The survey revealed that most treaters currently collect data that are mainly related to the haemostatic treatment (consumption of concentrates) and the bleeding symptoms (number and location of bleeds) in a non-uniform and non-standardized way. By contrast, functional, physical and quality of life scorings are rarely used and show considerable heterogeneity between treaters. Also, many disparities emerged between practice and perception, in particular quality of life data that are perceived as being important but for most of the time are not collected. This survey represents, in our view, the first attempt to evaluate the actual utilization of outcome measures in haemophilia care. While the value of outcome measures is appreciated, they are not assessed regularly. Therefore, there is a need to include appropriate performance indicators (outcome measures) of haemophilia care in routine clinical practice. Consensus recommendations to provide a framework for achieving this aim are provided. © 2016 John Wiley & Sons Ltd.

    Full Text Available Empirical social contact patterns are essential to understand the spread of infectious diseases. To date, no such data existed for France. Although infectious diseases are frequently seasonal, the temporal variation of contact patterns has not been documented hitherto.COMES-F is the first French large-scale population survey, carried out over 3 different periods (February-March, April, April-May with some participants common to the first and the last period. Participants described their contacts for 2 consecutive days, and reported separately on professional contacts when typically over 20 per day.2033 participants reported 38 881 contacts (weighted median [first quartile-third quartile]: 8[5-14] per day, and 54 378 contacts with supplementary professional contacts (9[5-17]. Contrary to age, gender, household size, holidays, weekend and occupation, period of the year had little influence on the number of contacts or the mixing patterns. Contact patterns were highly assortative with age, irrespective of the location of the contact, and gender, with women having 8% more contacts than men. Although most contacts occurred at home and at school, the inclusion of professional contacts modified the structure of the mixing patterns. Holidays and weekends reduced dramatically the number of contacts, and as proxies for school closure, reduced R0 by 33% and 28%, respectively. Thus, school closures could have an important impact on the spread of close contact infections in France.Despite no clear evidence for temporal variation, trends suggest that more studies are needed. Age and gender were found important determinants of the mixing patterns. Gender differences in mixing patterns might help explain gender differences in the epidemiology of infectious diseases.

    Ceramics can be defmed as a material consisting of hard brittle properties produced from inorganic and nonmetallic minerals made by firing at high temperatures. These materials are compounds between metallic and nonmetallic elements and are either totally ionic, or predominately ionic but having some covalent character. This definition allows for a large range of materials, not all applicable to refractory applications. As this report is focused on potential ceramic materials for high temperature, aggressive exposure applications, the ceramics reviewed as part of this report will focus on refractory ceramics specifically designed and used for these applications. Ceramic materials consist of a wide variety of products. Callister (2000) 1 characterized ceramic materials into six classifications: glasses, clay products, refractories, cements, abrasives, and advanced ceramics. Figure 1 shows this classification system. This review will focus mainly on refractory ceramics and cements as in general, the other classifications are neither applicable nor economical for use in large structures such as the flame trench. Although much work has been done in advanced ceramics over the past decade or so, these materials are likely cost prohibitive and would have to be fabricated off-site, transported to the NASA facilities, and installed, which make these even less feasible. Although the authors reviewed the literature on advanced ceramic refractories 2 center dot 3 center dot 4 center dot 5 center dot 6 center dot 7 center dot 8 center dot 9 center dot 10 center dot 11 center dot 12 after the review it was concluded that these materials should not be ' the focus of this report. A review is in progress on materials and systems for prefabricated refractory ceramic panels, but this review is focusing more on typical refractory materials for prefabricated systems, which could make the system more economically feasible. Refractory ceramics are used for a wide variety of applications

    2015-08-01

    Full Text Available This review sets out to explore the relatively new and unique parental experience of mediating children’s use of Internet connected devices (ICDs in Ireland. A coherent understanding of the core concepts that emerged from the literature is presented in a way that connects broad theoretical concepts to specific contexts. An overview of parental experience and the relationship between parental experience and the theoretical aspects of psychology, counselling and psychotherapy is presented. ICDs are briefly explained and a working definition is established for the purpose of this review. The literature on parental mediation of children’s use of ICDs is explored and segmented into risks and benefits. Literature on parental strategies for mediation of children’s use of ICDs is reviewed. The relationship between trust, parenting styles and the concept of child self-regulation is explored. Literature is reviewed to place an Irish context on the parental experience in the mediation of ICDs. The review concludes with a discussion and summary conclusions based on the literature reviewed that creates a chain of evidence in support of additional research.

    In Mali, the empirical knowledge on plant medicine is held by traditional practioners. Scientific studies have been carried on some plants and they have confirmed their local uses, but few data are available on the toxicity of Malian medicinal plants. In the present work, we record the toxic plants used as medicines in the Bamako district, Mali, with the aim to evaluate the knowledge of traditional healers and herbalists on the toxicity of the plant used. A survey was carried out on the market places in the Bamako district and 106 healers and herbalists were interviewed. A survey of the scientific literature was conducted to verify or sustain the claimed toxicological data. Nineteen plants are arranged according to their frequency of quotation based on the questionnaire. The information includes the botanical name, literature survey on the pharmacology of the plants, the healers' knowledge on plant toxicity and its prevention by some of the healers.

    The aim of the present study was to determine to what extent macroscopical parameters mentioned in the literature are suitable for the estimation of the post mortem interval (PMI) and particularly for the exclusion of the forensically relevant resting period for recent bone material. The macroscopical examination of recent bone material with a known PMI showed that only one published parameter (relics of adipocere in the cross section of the compacta) was consistent with our findings for this particular resting period (27-28 years). Other macroscopical parameters presented in the literature were contradictory to the results observed in this study. Among those are the rigidity of bones, the adhesion of soft tissue, the filling of the marrow cavity, and the permeation of the epiphyses with adipocere. Concerning the exclusion of the forensically relevant resting period, a similar result was observed. This study identified some diagnostic findings in bones with a resting period of less than 50 years which according to the literature should only be present after a resting period of more than 50 years. These features included the lack of macroscopical traces of adipocere, degradation of the compacta surface, detachment of the cortical substance, the ability of bone to be broken with bare hands, and superficial usures. Moreover, in one-third of our cases we identified some intra-individual differences not previously described in the literature. In addition to the other results, those intra-individual differences make an estimation of the PMI more difficult. However it should be noted that those published parameters were collected from bone material which was stored in a "relatively arid sand-grit-clay soil of the broken stone layer of Munich". The bones in the present study were stored in acidic and clayey-loamy soil, partly with lateral water flow. In conclusion, the present study demonstrates that one should use caution estimating the post mortem interval and excluding

    Medical imaging education often has limited representation in formal medical student curricula. Although the need for greater inclusion of radiology material is generally agreed on, the exact skillset that should be taught is less clear. The purpose of our study was to perform a needs assessment for a national radiology curriculum for medical students. We analyzed data from previous unpublished portions of the American College of Radiology/Alliance of Medical Student Educators in Radiology survey of Deans and Radiology Chairs regarding prevalence of radiology curricular revisions, assessment tools, use of the American College of Radiology Appropriateness Criteria, and resources used in curriculum revision. We also performed a literature search through both PubMED and a general search engine (Google) to identify available resources for designing and implementing imaging curricula and curricular revisions. Medical school deans and chairs reported a need for more overall radiology content; one of every six programs (15%) reported they had no recognized imaging curriculum. Of schools currently with imaging curricula, 82% have undergone revision in the last 10 years using a variety of different resources, but there is no universally agreed on guide or standard curriculum. The PubMED and Google searches identified only 23 and eight resources, respectively, suggesting a sizable deficit in available guidance; however, a single published medical student radiology curriculum is available through the Alliance of Medical Student Educators in Radiology. There is a need, but few available resources, to guide educators in adding imaging content to medical school curricula. We postulate that a standardized national curriculum directed by a focused skillset may be useful to educators and could result in greater uniformity of imaging skills among graduating US medical students. A proposed skillset to guide a national curriculum in radiology is described. Copyright © 2015 AUR

  12. Accounting for the Uncertainty Related to Building Occupants with Regards to Visual Comfort: A Literature Survey on Drivers and Models

    Directory of Open Access Journals (Sweden)

    Valentina Fabi

    2016-02-01

    Full Text Available The interactions between building occupants and control systems have a high influence on energy consumption and on indoor environmental quality. In the perspective of a future of “nearly-zero” energy buildings, it is crucial to analyse the energy-related interactions deeply to predict realistic energy use during the design stage. Since the reaction to thermal, acoustic, or visual stimuli is not the same for every human being, monitoring the behaviour inside buildings is an essential step to assert differences in energy consumption related to different interactions. Reliable information concerning occupants’ behaviours in a building could contribute to a better evaluation of building energy performances and design robustness, as well as supporting the development of occupants’ education to energy awareness. The present literature survey enlarges our understanding of which environmental conditions influence occupants’ manual controlling of the system in offices and by consequence the energy consumption. The purpose of this study was to investigate the possible drivers for light-switching to model occupant behaviour in office buildings. The probability of switching lighting systems on or off was related to the occupancy and differentiated for arrival, intermediate, and departure periods. The switching probability has been reported to be higher during the entering or the leaving time in relation to contextual variables. In the analysis of switch-on actions, users were often clustered between those who take daylight level into account and switch on lights only if necessary and people who totally disregard the natural lighting. This underlines the importance of how individuality is at the base of the definition of the different types of users.

Most of the reported cases of PFA pseudoaneurysm in the English literature developed after penetrating trauma, surgical procedures, and femur fractures. We present two such cases following blunt trauma and without any associated long bone injury. After initial imaging failed to show any long bone fracture, CT angiography confirmed pseudoaneurysm of the branch of the PFA. Both patients were then treated with emergent coil embolization of the bleeding vessel. Pseudoaneurysms typically present late and signs of persistent hip pain, thigh swelling, presence of a pulsatile mass, and even unexplained anemia all may suggest the diagnosis. Recognition of PFA pseudoaneurysm requires high index of suspicion and is often difficult to diagnose clinically because of its location. PMID:28246563

    Full Text Available Bullet embolism within the gastrointestinal system is extremely rare. Such bullet injuries are infrequently covered in the general literature, but the surgeon should be aware of the phenomenon. Smaller caliber bullets are more common in civilian gunshot wound (GSW events. These bullets are able to tumble through the gastrointestinal tract and cause perforation of the intestinal lumen which is small enough to be easily missed. Bullets retained in the abdominal cavity should not be dismissed as fixed and should be carefully monitored to ensure that they do not embolize within the bowel and cause occult lesions during their migration. We present a unique case wherein a bullet caused a minute perforation in the small bowel, before migrating to the distal colon, which resulted in late presentation of sepsis secondary to peritonitis.

    Composite end points are frequently used in reports of clinical trials. One rationale for the use of composite end points is to account for competing risks. In the presence of competing risks, the event rate of a specific event depends on the rates of other competing events. One proposed solution is to include all important competing events in one composite end point. Clinical trialists require guidance regarding when this approach is appropriate. To identify publications describing criteria for use of composite end points for competing risk and to offer guidance regarding when a composite end point is appropriate on the basis of competing risks. We searched MEDLINE, CINAHL, EMBASE, The Cochrane's Central & Systematic Review databases including the Health Technology Assessment database, and the Cochrane's Methodology register from inception to April 2015, and candidate textbooks, to identify all articles providing guidance on this issue. Eligible publications explicitly addressed the issue of a composite outcome to address competing risks. Two reviewers independently screened the titles and abstracts for full-text review; independently reviewed full-text publications; and abstracted specific criteria authors offered for use of composite end points to address competing risks. Of 63,645 titles and abstracts, 166 proved potentially relevant of which 43 publications were included in the final review. Most publications note competing risks as a reason for using composite end points without further elaboration. None of the articles or textbook chapters provide specific criteria for use of composite end points for competing risk. Some advocate using composite end points to avoid bias due to competing risks and others suggest that composite end points seldom or never be used for this purpose. We recommend using composite end points for competing risks only if the competing risk is plausible and if it occurs with sufficiently high frequency to influence the interpretation

  17. Perceptions of document relevance

    Full Text Available This article presents a study of how humans perceive the relevance of documents.Humans are adept at making reasonably robust and quick decisions about what information is relevant to them, despite the ever increasing complexity and volume of their surrounding information environment. The literature on document relevance has identified various dimensions of relevance (e.g., topicality, novelty, etc., however little is understood about how these dimensions may interact.We performed a crowdsourced study of how human subjects judge two relevance dimensions in relation to document snippets retrieved from an internet search engine.The order of the judgement was controlled.For those judgements exhibiting an order effect, a q-test was performed to determine whether the order effects can be explained by a quantum decision model based on incompatible decision perspectives.Some evidence of incompatibility was found which suggests incompatible decision perspectives is appropriate for explaining interacting dimensions of relevance.

    1982-10-01

    The US Nuclear Regulatory Commission has initiated the Fuel Cycle Risk Assessment Program to provide risk assessment methods for assistance in the regulatory process for nuclear fuel cycle facilities other than reactors. Both the once-through cycle and plutonium recycle are being considered. A previous report generated by this program defines and describes fuel cycle facilities, or elements, considered in the program. This report, the second from the program, describes the survey and computer compilation of fuel cycle risk-related literature. Sources of available information on the design, safety, and risk associated with the defined set of fuel cycle elements were searched and documents obtained were catalogued and characterized with respect to fuel cycle elements and specific risk/safety information. Both US and foreign surveys were conducted. Battelle's computer-based BASIS information management system was used to facilitate the establishment of the literature compilation. A complete listing of the literature compilation and several useful indexes are included. Future updates of the literature compilation will be published periodically. 760 annotated citations are included.

  1. Emergent Median Sternotomy for Mediastinal Hematoma: A Rare Complication following Internal Jugular Vein Catheterization for Chemoport Insertion—A Case Report and Review of Relevant Literature

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Mediastinal hematoma is a rare complication following insertion of a central venous catheter with only few cases reported in the English literature. We report a case of a 71-year-old female who was admitted for elective chemoport placement. USG guided right internal jugular access was attempted using the Seldinger technique. Resistance was met while threading the guidewire. USG showed a chronic clot burden in the RIJ. A microvascular access was established under fluoroscopic guidance. Rest of the procedure was completed without any further issues. Following extubation, the patient complained of right-sided chest pain radiating to the back. Chest X-ray revealed a contained white out in the right upper lung field. She became hemodynamically unstable. Repeated X-ray showed progression of the hematoma. Median Sternotomy showed posterior mediastinal hematoma tracking into right pleural cavity. Active bleeding from the puncture site at RIJ-SCL junction was repaired. Patient had an uneventful recovery. Injury to the central venous system is the result of either penetrating trauma or iatrogenic causes as in our case. A possible explanation of our complication may be attributed to the forced manipulation of the dilator or guidewire against resistance. Clavicle and sternum offer bony protection to the underlying vital venous structures and injuries often need sternotomy with or without neck extension. Division of the clavicle and disarticulation of the sternoclavicular joint may be required for optimum exposure. Meticulous surgical technique, knowledge of the possible complications, and close monitoring in the postprocedural period are of utmost importance. Chest X-ray showed to be routinely done to detect any complication early.

    Full Text Available Partindo-se do suposto de que as estatísticas de saúde devem compor um conjunto organizado de dados provenientes dos registros civil, da produção de serviços, das bases de dados de morbi-mortalidade, procura-se enfatizar a necessidade de coletar dados sobre saúde e uso de serviços de saúde, que só podem ser gerados por inquéritos populacionais periódicos, complementando dessa forma as deficiências das informações para monitorar e avaliar as condições de saúde e o desempenho do sistema de saúde brasileiro. Faz-se uma apresentação dos inquéritos desenvolvidos em alguns países, seus enfoques principais e as limitações mais gerais. Finalmente, apresenta-se a produção mais recente de documentos e revisões internacionais sobre os mecanismos que vêm sendo utilizados em outros países para a formulação de uma política de informação em saúde como parte da agenda da reforma do setor saúde, que poderiam de certa forma apontar para alguns caminhos no caso brasileiro.Assuming that health statistics should be considered as an organized data system composed by vital statistics, administrative records, morbidity and mortality data, it is stressed the relevance in generating population based statistics on health status and use of health services as a compensation for the limitations of health services data that are based on users of the health system or vital statistics not always associated with social variables. Health surveys are the only way to generate health information to evaluate the health system performance and the monitoring of social inequalities in health and in the use of health services. It is pointed out some main issues concerning the use of health surveys by other countries and the methods employed to build a health statistics system as part of the health sector reform. Some of the possibilities and limitations of the Brazilian health information system are discussed as well.

    2014-04-01

    Scant research has been undertaken regarding chiropractors' skills and knowledge associated with evidence-based practice (EBP), and their perceived barriers to EBP. These issues appear to have been examined in only one small qualitative study and one small study of chiropractors holding orthopaedic diplomas. The lack of research in this area suggests that additional studies are warranted to develop a better understanding of factors that affect chiropractors' use of research evidence in clinical practice. We used a modified online questionnaire that captured information regarding EBP skills and knowledge, and barriers to EBP. Its adaption was informed by the use of a content validity panel. The questionnaire was disseminated through email by Australian chiropractic professional organisations and the Chiropractic Board of Australia. Logistic regression analyses were conducted to examine univariate associations between responses to items measuring knowledge and skills with items measuring: age; years since registration; reading research literature; and use of research literature in clinical decision-making. 584 respondents returned questionnaires. About half of the respondents stated they had learned the foundations of EBP (56.6%) during their undergraduate training. Slightly more than two thirds of the respondents were confident in their ability to critically review literature (69.5%) and find relevant research to answer clinical questions (72.6%). The most common factors involved with reading more research, and increased use of research literature in clinical decision-making, were confidence in critical appraisal skills and confidence in finding relevant research literature. Conclusion Educational interventions should be implemented to enhance Australian chiropractors' fundamental EBP skills. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Objective Based on the literatures review of "mutual restrained food combinations", the current cognition of some groups of people in Lanzhou area was surveyed and both the animal experiment and human study were performed to provide scientific evidences for better understanding of this hearsay, whether it was right or wrong. Method The full-text database from Chinese periodicals and relevant books collected from the bookstores were used as the source of information.1346 subjects were randomly chosen from Lanzhou area for survey of cognition about "mutual restrained food combinations"with questionnaires. 50 Kunming mice were randomly divided into 5 groups, one fed the basic diet as control and the other groups fed 4 "mutual restrained food combinations" respectively. The feed consumed, body weight, hemogram, liver and kidney function tests of the animals were observed and the histo-pathological pictures of main organs were examined as well.30 males and 30 females selected from Lanzhou city were divided into 6 groups. One group consumed usual diet as control and the other 5 consumed diet with 5 "mutual restrained food combinations" respectively. Their subjective feeling and adverse reactions were recorded during 7 d. Results Most statements about "mutual restrained food combinations" in literatures and books was without scientific evidences. The major source of these informations was from books, periodicals,television programs, and communications with relatives and friends. The farmers obtained the lowest mean score in the knowledge about "mutual restrainal food combinations", while the college students obtained higher scores than other groups.The animal experiment showed that neither physical and behavioral disorders nor biochemical and morphological changes were observed in mice fed with 4 pairs of "mutual restrained combined foods". There were also no clinical symptoms or adverse reactions observed in human subjects after eating 5 "mutual restrained combined foods

    This literature review presents treatment options for nitrate, iodine-129, and uranium, which are present in groundwater at the 200-ZP-I Groundwater Operable Unit (OU) within the 200 West Area of the Hanford Site. The objective of this review is to determine available methods to treat or sequester these contaminants in place (i.e., in situ) or to pump-and-treat the groundwater aboveground (i.e., ex situ). This review has been conducted with emphasis on commercially available or field-tested technologies, but theoretical studies have, in some cases, been considered when no published field data exist. The initial scope of this literature review included only nitrate and iodine-I 29, but it was later expanded to include uranium. The focus of the literature review was weighted toward researching methods for treatment of nitrate and iodine-129 over uranium because of the relatively greater impact of those compounds identified at the 200-ZP-I OU.

    In this regard, the present article aims at achieving three essential objectives. First, we will introduce a common indicator for circular job mobility patterns found in the two surveys. On the basis of this common indicator, we will comparatively analyse the prevalence of different mobility forms and their composition according to key socio-demographic characteristics. In addition, we will use multivariate analyses to illustrate the relevance of job mobility for partnership and family development. Results suggest mobility patterns to be an important individual context factor when explaining processes relevant to partnerships and family. In particular, women who exhibit some degree of job mobility are less often married and rarely have children.

  15. Persistent left superior vena cava: review of the literature, clinical implications, and relevance of alterations in thoracic central venous anatomy as pertaining to the general principles of central venous access device placement and venography in cancer patients.

    2011-12-28

    Persistent left superior vena cava (PLSVC) represents the most common congenital venous anomaly of the thoracic systemic venous return, occurring in 0.3% to 0.5% of individuals in the general population, and in up to 12% of individuals with other documented congential heart abnormalities. In this regard, there is very little in the literature that specifically addresses the potential importance of the incidental finding of PLSVC to surgeons, interventional radiologists, and other physicians actively involved in central venous access device placement in cancer patients. In the current review, we have attempted to comprehensively evaluate the available literature regarding PLSVC. Additionally, we have discussed the clinical implications and relevance of such congenital aberrancies, as well as of treatment-induced or disease-induced alterations in the anatomy of the thoracic central venous system, as they pertain to the general principles of successful placement of central venous access devices in cancer patients. Specifically regarding PLSVC, it is critical to recognize its presence during attempted central venous access device placement and to fully characterize the pattern of cardiac venous return (i.e., to the right atrium or to the left atrium) in any patient suspected of PLSVC prior to initiation of use of their central venous access device.

    2013-09-01

    Used nuclear fuel is currently being reprocessed in only a few countries, notably France, England, Japan, and Russia. The need to control emissions of the gaseous radionuclides to the air during nuclear fuel reprocessing has already been reported for the entire plant. But since the gaseous radionuclides can partition to various different reprocessing off-gas streams, for example, from the head end, dissolver, vessel, cell, and melter, an understanding of each of these streams is critical. These off-gas streams have different flow rates and compositions and could have different gaseous radionuclide control requirements, depending on how the gaseous radionuclides partition. This report reviews the available literature to summarize specific engineering data on the flow rates, forms of the volatile radionuclides in off-gas streams, distributions of these radionuclides in these streams, and temperatures of these streams. This document contains an extensive bibliography of the information contained in the open literature.

    Pioro, I.L.; Duffey, R.B

    2003-04-01

    This survey consists of 430 references, including 269 Russian publications and 161 Western publications devoted to the problems of heat transfer and hydraulic resistance of a fluid at near-critical and supercritical pressures. The objective of the literature survey is to compile and summarize findings in the area of heat transfer and hydraulic resistance at supercritical pressures for various fluids for the last fifty years published in the open Russian and Western literature. The analysis of the publications showed that the majority of the papers were devoted to the heat transfer of fluids at near-critical and supercritical pressures flowing inside a circular tube. Three major working fluids are involved: water, carbon dioxide, and helium. The main objective of these studies was the development and design of supercritical steam generators for power stations (utilizing water as a working fluid) in the 1950s, 1960s, and 1970s. Carbon dioxide was usually used as the modeling fluid due to lower values of the critical parameters. Helium, and sometimes carbon dioxide, were considered as possible working fluids in some special designs of nuclear reactors. (author)

  20. THE HYDROTHERMAL REACTIONS OF MONOSODIUM TITANATE, CRYSTALLINE SILICOTITANATE AND SLUDGE IN THE MODULAR SALT PROCESS: A LITERATURE SURVEY

    Energy Technology Data Exchange (ETDEWEB)

    Fondeur, F.; Pennebaker, F.; Fink, S.

    2010-11-11

    The use of crystalline silicotitanate (CST) is proposed for an at-tank process to treat High Level Waste at the Savannah River Site. The proposed configuration includes deployment of ion exchange columns suspended in the risers of existing tanks to process salt waste without building a new facility. The CST is available in an engineered form, designated as IE-911-CW, from UOP. Prior data indicates CST has a proclivity to agglomerate from deposits of silica rich compounds present in the alkaline waste solutions. This report documents the prior literature and provides guidance for the design and operations that include CST to mitigate that risk. The proposed operation will also add monosodium titanate (MST) to the supernate of the tank prior to the ion exchange operation to remove strontium and select alpha-emitting actinides. The cesium loaded CST is ground and then passed forward to the sludge washing tank as feed to the Defense Waste Processing Facility (DWPF). Similarly, the MST will be transferred to the sludge washing tank. Sludge processing includes the potential to leach aluminum from the solids at elevated temperature (e.g., 65 C) using concentrated (3M) sodium hydroxide solutions. Prior literature indicates that both CST and MST will agglomerate and form higher yield stress slurries with exposure to elevated temperatures. This report assessed that data and provides guidance on minimizing the impact of CST and MST on sludge transfer and aluminum leaching sludge.

    This study describes the current roles of dental librarians in Evidence-based Dentistry (EBD) education including their perceptions of EBD and barriers to their involvement. A Web-based survey was distributed to the dental librarians in North America, with a 71% response rate. The results showed that the majority of dental librarians are playing multiple and diverse roles in EBD education. The most frequently cited barrier to their involvement is the low level of interest from the dental faculty/student/school. Most dental librarians felt competent in supporting EBD, although continuing education needs in both EBD and teaching skills were pointed out.

    2016-12-15

    In order to characterize the state of oil spill research and describe how the field has changed since its inception in the 1960s and since the Deepwater Horizon spill in 2010, we examined approximately 10% of oil spill literature (1255 of over 11,000 publications) published from 1968 to 2015. We find that, despite its episodic nature, oil spill research is a rapidly expanding field with a growth rate faster than that of science as a whole. There is a massive post-Deepwater Horizon shift of research attention to the Gulf of Mexico, from 2% of studies in 2004-2008 to 61% in 2014-2015, thus ranking Deepwater Horizon as the most studied oil spill. There is, however, a longstanding gap in research in that only 1% of studies deal with the effects of oil spills on human health. These results provide a better understanding of the current trends and gaps within the field.

    Management of melanoma during pregnancy can be extremely challenging. The reported incidence of melanoma in pregnancy ranges from 2.8 to 5.0 per 100 000 pregnancies. There are no guidelines for the management of melanoma during pregnancy. The survey was designed to investigate the opinions of melanoma physicians on decision making in relation to pregnancy and melanoma. A clinical scenario-based survey on management of pregnancy in melanoma was distributed all over Europe via the membership of the EORTC and other European melanoma societies. A total of 290 questionnaires were returned with a larger participation from southern Europe. A large heterogeneity was found for the answers given in the different clinical scenarios with 50% of the answers showing discordance, especially regarding sentinel lymph node biopsy during pregnancy. Discordant answers were also found for the counselling of women about a potential delay in getting pregnant after a high-risk melanoma (35% for a 2 year wait minimum vs. 57% no waiting needed), while for thin melanomas, as expected, there was more concordance with 70% of the physicians recommending no delay. Fifteen per cent of physicians recommended an abortion in stage II melanoma during the third month of pregnancy. Twenty per cent of the responders advised against hormonal replacement therapy in melanoma patients. The management of melanoma during pregnancy varies widely in Europe.

    The aims of the present systematic literature analysis were to evaluate, over a 10-year period, the trend of the proportion of RCT, SR, MA published on endodontic surgery, and to investigate if the impact factor (IF) of the main endodontic Journals correlates with the proportion of RCT, SR, MA they publish. An electronic search of the RCT, SR and MA published on the topic "endodontic surgery" from 2001 to 2010 was performed on Medline and Cochrane CENTRAL database using specific search terms combined with Boolean operators. Endodontic Journals impact factor was retrieved by the Thomson Scientific database. The proportion of each study type over the total number of articles on endodontic surgery published per year was estimated. The correlation between the number of high-evidence level studies published on the main endodontic Journals and the IF of such Journals per year was estimated. From a total of 900 articles published in 2001-2010 on endodontic surgery, there were 114 studies of high evidence level. A significant increase of the proportion of either RCT, SR and MA over the years was found. A modest to unclear correlation was found between the Journal IF and the number of high-evidence articles published. There is a positive trend over the years among researchers in performing studies of good quality in endodontic surgery. The impact factor of endodontic Journals is not consistently influenced by publication of high-evidence level articles. Copyright © 2015 Elsevier Inc. All rights reserved.

    2016-08-01

    In recent years, several online tools have appeared capable of identifying potential plagiarism in science. While such tools may help to maintain or even increase the originality and ethical quality of the scientific literature, no apparent consensus exists among editors on the degree of plagiarism or self-plagiarism necessary to reject or retract manuscripts. In this study, two entire volumes of published original papers and reviews from Basic & Clinical Pharmacology & Toxicology were retrospectively scanned for similarity in anonymized form using iThenticate software to explore measures to predictively identify true plagiarism and self-plagiarism and to potentially provide guidelines for future screening of incoming manuscripts. Several filters were applied, all of which appeared to lower the noise from irrelevant hits. The main conclusions were that plagiarism software offers a unique opportunity to screen for plagiarism easily but also that it has to be employed with caution as automated or uncritical use is far too unreliable to allow a fair basis for judging the degree of plagiarism in a manuscript. This remains the job of senior editors. Whereas a few cases of self-plagiarism that would not likely have been accepted with today's guidelines were indeed identified, no cases of fraud or serious plagiarism were found. Potential guidelines are discussed.

    A survey of mortality in hedgehogs (Erinaceus europaeus) was carried out between July 1976 and November 1986. Most were from Norfolk. Of the 74 examined, 35 (47.3 per cent) were road casualties, one of which yielded Salmonella typhimurium phage type (PT) 104. Of the remaining 39, 13 (33.3 per cent) had salmonellosis due to S enteritidis PT 11. This organism, which appears to be common and widespread in hedgehogs in England was found in 10 separate incidents. The only other zoonosis was ringworm (Trichophyton erinacei infection). Other findings included ectoparasitic infestations with mange mites (Caparinia tripilis), fleas (Archaeopsylla erinacei) and ticks (Ixodes hexagonus). Helminths comprised Crenosoma striatum lungworms (associated with Bordetella bronchiseptica infection in one animal), intestinal nematodes (Capillaria species), cestodes (Rodentolepis erinacei), trematodes (Brachylaemus erinacei) and acanthocephalans (Prosthoryhnchus species). Metaldehyde poisoning was diagnosed in three animals. Over a 10 year period 370 carcases were counted on a stretch of 18 miles of road in Norfolk. The major causes of mortality are probably road casualties and hypothermia during the winter months. In December 1988 S enteritidis PT 11 was isolated from three of four carcases examined in Berkshire and the zoonosis pseudotuberculosis (Yersinia pseudotuberculosis infection) was diagnosed in two of them.

    2011-09-01

    We reviewed the world literature on solitary fibrous tumors of the central nervous system from August 1996 to July 2011, focusing on both clinicopathological features and diagnostic findings. The anatomical distribution of the 220 cases reported so far reveals that most are intracranial and just over one-fifth are intraspinal. In decreasing frequency, intracranial tumors involve the supratentorial and infratentorial compartments, the pontocerebellar angle, the sellar and parasellar regions, and the cranial nerves. Intraspinal tumors are mainly located in the thoracic and cervical segments. Although most solitary fibrous tumors of the central nervous system are dural based, a small subset presents as subpial, intraparenchymal, intraventricular, or as tumors involving the nerve rootlets with no dural connection. Preoperative imaging and intraoperative findings suggest meningioma, schwannoma or neurofibroma, hemangiopericytoma, or pituitary tumors. Immunohistochemistry is critical to establish a definitive histopathological diagnosis. Vimentin, CD34, BCL2, and CD99 are the most consistently positive markers. The usual histologic type generally behaves in a benign manner if complete removal is achieved. Recurrence is anticipated when resection is subtotal or when the tumor exhibits atypical histology. The proliferative index as assessed by MIB1 labeling is of prognostic significance. Occasionally, tumors featuring conventional morphology may recur, perhaps because of minimal residual disease left behind during surgical extirpation. Rare extracranial metastases and tumor-related deaths are on record. Surgery is the treatment of choice. Stereotactic and external beam radiation therapy may be indicated for postsurgical tumor remnants and for unresectable recurrences. Long-term active surveillance of the patients is mandatory.

  8. MSAP markers and global cytosine methylation in plants: a literature survey and comparative analysis for a wild-growing species.

    Methylation of DNA cytosines affects whether transposons are silenced and genes are expressed, and is a major epigenetic mechanism whereby plants respond to environmental change. Analyses of methylation-sensitive amplification polymorphism (MS-AFLP or MSAP) have been often used to assess methyl-cytosine changes in response to stress treatments and, more recently, in ecological studies of wild plant populations. MSAP technique does not require a sequenced reference genome and provides many anonymous loci randomly distributed over the genome for which the methylation status can be ascertained. Scoring of MSAP data, however, is not straightforward, and efforts are still required to standardize this step to make use of the potential to distinguish between methylation at different nucleotide contexts. Furthermore, it is not known how accurately MSAP infers genome-wide cytosine methylation levels in plants. Here, we analyse the relationship between MSAP results and the percentage of global cytosine methylation in genomic DNA obtained by HPLC analysis. A screening of literature revealed that methylation of cytosines at cleavage sites assayed by MSAP was greater than genome-wide estimates obtained by HPLC, and percentages of methylation at different nucleotide contexts varied within and across species. Concurrent HPLC and MSAP analyses of DNA from 200 individuals of the perennial herb Helleborus foetidus confirmed that methyl-cytosine was more frequent in CCGG contexts than in the genome as a whole. In this species, global methylation was unrelated to methylation at the inner CG site. We suggest that global HPLC and context-specific MSAP methylation estimates provide complementary information whose combination can improve our current understanding of methylation-based epigenetic processes in nonmodel plants. © 2015 John Wiley & Sons Ltd.

    Full Text Available Abstract Background It is widely acknowledged that there is a global divide on health care and health research known as the 10/90 divide. Methods A retrospective survey of articles published in the BMJ, Lancet, NEJM, Annals of Internal Medicine & JAMA in a calendar year to examine the contribution of the developing world to medical literature. We categorized countries into four regions: UK, USA, Other Euro-American countries (OEAC and (RoW. OEAC were European countries other than the UK but including Australia, New Zealand and Canada. RoW comprised all other countries. Results The average contribution of the RoW to the research literature in the five journals was 6.5%. In the two British journals 7.6% of the articles were from the RoW; in the three American journals 4.8% of articles were from RoW. The highest proportion of papers from the RoW was in the Lancet (12%. An analysis of the authorship of 151 articles from RoW showed that 104 (68.9% involved authorship with developed countries in Europe or North America. There were 15 original papers in these journals with data from RoW but without any authors from RoW. Conclusions There is a marked under-representation of countries in high-impact general medical journals. The ethical implications of this inequity and ways of reducing it are discussed.

    Orthopaedics-related diseases and conditions are a significant burden worldwide. In this study, we aimed to compare the quantity and quality of research output in the field of orthopaedics from Mainland China (MC), USA, UK, Japan and Germany. The USA, UK, Japan, Germany and MC. We selected orthopaedics journals from the subject category 'orthopedics' from the Science Citation Index Expanded (SCIE). The number of publications, the number of publications in the surveyed publication types, impact factor (IF) and citations from the corresponding country from 2005 to 2014 were collected for quantity and quality comparisons. A total of 128 895 articles were published worldwide in orthopaedics-related journals from 2005 to 2014. The USA contributed the largest proportion (31 190 (24.20%)), followed by the UK (6703 (5.20%)), Japan (5718 (4.41%)), Germany (4701 (3.66%)) and MC (3389 (2.63%)). Publications from MC represented the fewest, but this quantity is rapidly increasing. The quantity of annual publications from MC has exceeded that of Germany since 2012. The USA plays a predominant role in all kinds of publication types under investigation in the study, except in the category of meta-analysis. MC was in the last place for cumulative IFs, and the average IF actually decreased from the beginning of the study. For total and average citations, MC still lags behind the other countries in the study. The USA has occupied the dominant place in orthopaedics-related research for the last 10 years. Although MC has made great progress in the number of published works in the field of orthopaedics over the last 10 years, the quality of these publishing efforts needs further improvement.

    The present study deals with the survey of inorganic ion-exchangers suitable for separation and immobilization of Sr and Cs contained in acidic high-level liquid waste. The stabilities of published waste forms and their preparation processes were evaluated from the standpoint of conversion of exchangers containing Sr and Cs into appropriate waste forms. The essential results are below. (1) For separation and immobilization of Cs, crystalline silicotitanate seems to be the most promising exchanger. Insoluble ferrocyanides and phosphates are not suitable for immobilization without additives. Mordenite is inexpensive and commercially available but it would dissolve in highly acidic media. (2) For selective separation of Sr, there is no promising exchanger up to now. It is necessary either to modify separation condition or to synthesize a novel exchanger. (3) Soluble salts, glasses and ceramics are proposed as a storage or disposal form of separated Sr and Cs. Ceramics sintered by hot-pressing are favorable waste forms of inorganic ion-exchangers but their leachabilities and thermal conductivities are largely influenced by qualities of products. Crystallinity of a sintered exchanger depends on its composition. Exchanges of low Cs contents are often converted into amorphous materials whose chemical stabilities depend on solubilities of components of exchangers. (4) A new exchanger to be synthesized is crystalline and selective toward Sr and Cs. One meq/g is enough for Sr and Cs capacities, which are restricted by thermal and transmutation effects. Composition of the exchanger should be selected from the point of a scenario of separation and disposal. The solubilities of SiO{sub 2}, TiO{sub 2}, ZrO{sub 2}, Nb{sub 2}O{sub 5} and Ta{sub 2}O{sub 5} are low in acidic media and those of Al{sub 2}O{sub 3}, TiO{sub 2} and ZrO{sub 2}, in disposal circumstances. (5) Future works are optimization of separation scheme including development of exchangers, simplification of

  13. Relevance in the science classroom: A multidimensional analysis

    Hartwell, Matthew F.

    While perceived relevance is considered a fundamental component of adaptive learning, the experience of relevance and its conceptual definition have not been well described. The mixed-methods research presented in this dissertation aimed to clarify the conceptual meaning of relevance by focusing on its phenomenological experience from the students' perspective. Following a critical literature review, I propose an identity-based model of perceived relevance that includes three components: a contextual target, an identity target, and a connection type, or lens. An empirical investigation of this model that consisted of two general phases was implemented in four 9th grade-biology classrooms. Participants in Phase 1 (N = 118) completed a series of four open-ended writing activities focused on eliciting perceived personal connections to academic content. Exploratory qualitative content analysis of a 25% random sample of the student responses was used to identify the main meaning-units of the proposed model as well as different dimensions of student relevance perceptions. These meaning-units and dimensions provided the basis for the construction of a conceptual mapping sentence capturing students' perceived relevance, which was then applied in a confirmatory analysis to all other student responses. Participants in Phase 2 (N = 139) completed a closed survey designed based on the mapping sentence to assess their perceived relevance of a biology unit. The survey also included scales assessing other domain-level motivational processes. Exploratory factor analysis and non-metric multidimensional scaling indicated a coherent conceptual structure, which included a primary interpretive relevance dimension. Comparison of the conceptual structure across various groups (randomly-split sample, gender, academic level, domain-general motivational profiles) provided support for its ubiquity and insight into variation in the experience of perceived relevance among students of different

    Full Text Available Kashin-Beck disease (KBD is an endemic and chronic osteochondropathy. This disease principally occurs in the Tibet Autonomous Region and in several provinces of the People's Republic of China. The etiology of the disease remains obscure although environmental factors are assumed to be involved. Diet, in particular, differentiates the rural community, affected by KBD, from the other communities (nomads and city-dwellers, who remain unaffected. In anticipation of a nutrition survey, this study aimed to measure the mineral content (Ca, P, Mg, Fe, Zn, Mn, Cu, Ni, Se, Al, Sr, Mo, Cd, As, Pb, Hg, Cr, and Co of eight Tibetan staple foods and to compare the results against two food composition tables (FCTs. Foods were sampled in twenty households selected from both an endemic and a non-endemic area of rural Tibet. Ten minerals involved in bone metabolism were measured using atomic and molecular spectrometric methods. Results revealed that a very limited number of food/constituent pairs showed a variation in mineral composition during a single year of testing for a given region. In addition, results showed significant differences in mineral content between the endemic and the non-endemic area, especially for wheat flour. Following our analysis of the mineral content of the Tibetan food samples, results were statistically compared with similar foods listed in two food composition tables: the USDA National Nutrient Database (USDA Food Search for Windows, Version 1.0, database version SR23, and the China Food Composition Table (book 1, 2nd edition. More than 50 to 60% of p-values < 0.05 were highlighted, suggesting the inappropriateness of using FCTs as a reference for nutrition surveys in rural Tibet, and emphasizing the need for analysis of traditional foods. Differences were found to be more or less marked depending on the element considered, and calcium content seemed to show the greatest difference. Although it is obviously too early for definite

    Women age 45 years or younger with breast cancer, or who are at high-risk for breast cancer due to previously having the disease or to genetic risk, have distinct health risks and needs from their older counterparts. Young women frequently seek health information through the Internet and mainstream media, but often find it does not address their particular concerns, that it is difficult to evaluate or interpret, or even misleading. To help women better understand media coverage about new research, Facing Our Risk of Cancer Empowered (FORCE) developed the CDC-funded XRAYS (eXamining Relevance of Articles to Young Survivors) program. To assure that the XRAYS program is responsive to the community's needs, FORCE launched a web-based survey to assess where young women seek information about breast cancer, and to learn their unmet information needs. A total of 1,178 eligible women responded to the survey. In general, the breast cancer survivors and high-risk women between ages 18-45 years who responded to this survey, are using multiple media sources to seek information about breast cancer risk, prevention, screening, and treatment. They place trust in several media sources and use them to inform their medical decisions. Only about one-third of respondents to this survey report discussing media sources with their health care providers. Current survey results indicate that, by providing credible information on the quality of evidence and reporting in media reports on cancer, XRAYS is addressing a key need for health information. Results suggest that it will be useful for XRAYS to offer reviews of articles on a broad range of topics that can inform decisions at each stage of risk assessment and treatment.

    Cytochrome P450 enzymes (CYP) can be inhibited or induced by drugs, resulting in clinically significant drug-drug interactions that can cause unanticipated adverse reactions or therapeutic failures. The objective of the study was to analyze the in vivo inhibitory potential of the beta-blockers bisoprolol and metoprolol as well as the low-potency antipsychotic melperone on CYP2D6. By utilizing a large therapeutic drug monitoring database of 2874 samples, data from patients who had been treated with venlafaxine (VEN) either without (control group) or with a concomitant medication with bisoprolol, metoprolol or melperone were evaluated retrospectively to study the CYP2D6-catalyzed O-demethylation to O-desmethylvenlafaxine (ODVEN). Dose-adjusted serum levels (C/D) of VEN and ODVEN as well as the metabolic ratios (ODVEN/VEN) were computed for the four groups and compared using Kruskal-Wallis test. In total, 381 patients could be included for analysis. No significant difference was found in the median C/D (VEN), C/D (ODVEN) or C/D of the active moiety (VEN + ODVEN) in either the metoprolol (N = 103) or bisoprolol group (N = 101), compared to the control group (N = 108). In contrast, a significantly higher median C/D (VEN) (0.79 ng/ml/mg, range 0.13-5.73 ng/ml/mg) (P metoprolol has a clinically relevant inhibitory potential on CYP2D6.

We measured the extent of Internet use among cardiopathic patients and examined the effects that Internet use has on users' knowledge about their cardiac disease, health care matters and their use of the health care system. Methods We conducted a prospective survey among 255 cardiopathic patients at a German university hospital. Results Forty seven respondents (18 % used the internet and 8,8 % (n = 23 went online more than 20 hours per month. The most frequent reason for not using the internet was disinterest (52,3 %. Fourteen patients (5,4 % searched for specific disease-related information and valued the retrieved information on an analogous scale (1 = not relevant, 5 = very relevant on median with 4,0. Internet use is age and education dependent. Only 36 (14,1 % respondents found the internet useful, whereas the vast majority would not use it. Electronic scheduling for ambulatory visits or postoperative telemedical monitoring were rather disapproved. Conclusion We conclude that Internet use is infrequent among our study population and the search for relevant health and disease related information is not well established.

    The Declaration of Geneva is one of the core documents of medical ethics. A revision process was started by the World Medical Association (WMA) in 2016. The WMA has also used this occasion to examine how the Declaration of Geneva is used in countries throughout the world by conducting a survey of all WMA constituent members. The findings are highly important and raise urgent questions for the World Medical Association and its National Medical Associations (NMA): The Declaration of Geneva is only rarely used as an oath text despite the fact that physicians' oaths are generally widespread. This is not consistent with the intention and claim of the Declaration of Geneva. The article then discusses three questions. Should there be one single binding oath? Which organization should be responsible for such an oath? Which oath is the most obvious candidate? In a globalized world and despite all cultural diversity, the medical profession should have one core moral basis which is binding for physicians all over the world. The most obvious candidate for an oath incorporating this moral basis is the Declaration of Geneva.

    Of the many radionuclides and contaminants in the tank wastes stored at the Hanford site, technetium-99 (99Tc) is one of the most challenging to effectively immobilize in a waste form for ultimate disposal. Within the Hanford Tank Waste Treatment and Immobilization Plant (WTP), the Tc will partition between both the high-level waste (HLW) and low-activity waste (LAW) fractions of the tank waste. The HLW fraction will be converted to a glass waste form in the HLW vitrification facility and the LAW fraction will be converted to another glass waste form in the LAW vitrification facility. In both vitrification facilities, the Tc is incorporated into the glass waste form but a significant fraction of the Tc volatilizes at the high glass-melting temperatures and is captured in the off-gas treatment systems at both facilities. The aqueous off-gas condensate solution containing the volatilized Tc is recycled and is added to the LAW glass melter feed. This recycle process is effective in increasing the loading of Tc in the LAW glass but it also disproportionally increases the sulfur and halides in the LAW melter feed which increases both the amount of LAW glass and either the duration of the LAW vitrification mission or the required supplemental LAW treatment capacity.

    This document presents the literature survey results on Identification, Specification and Estimation (ISE) techniques for variables within the SiteParIden project. Besides an overview of the different general techniques also an overview is given on EU funded wind energy projects where some of these techniques have been applied more specifically. The main problem in applications like power performance assessment and site calibration is to establish an appropriate model for predicting the considered dependent variable with the aid of measured independent (explanatory) variables. In these applications detailed knowledge on what the relevant variables are and how their precise appearance in the model would be is typically missing. Therefore, the identification (of variables) and the specification (of the model relation) are important steps in the model building phase. For the determination of the parameters in the model a reliable variable estimation technique is required. In EU funded wind energy projects the linear regression technique is the most commonly applied tool for the estimation step. The linear regression technique may fail in finding reliable parameter estimates when the model variables are strongly correlated, either due to the experimental set-up or because of their particular appearance in the model. This situation of multicollinearity sometimes results in unrealistic parameter values, e.g. with the wrong algebraic sign. It is concluded that different approaches, like multi-binning can provide a better way of identifying the relevant variables. However further research in these applications is needed and it is recommended that alternative methods (neural networks, singular value decomposition etc.) should also be tested on their usefulness in a succeeding project. Increased interest in complex terrains, as feasible locations for wind farms, has also emphasised the need for adequate models. A common standard procedure to prescribe the statistical

    Full Text Available Abstract Background To assess the reporting of loss to follow-up (LTFU information in articles on randomised controlled trials (RCTs with time-to-event outcomes, and to assess whether discrepancies affect the validity of study results. Methods Literature survey of all issues of the BMJ, Lancet, JAMA, and New England Journal of Medicine published between 2003 and 2005. Eligible articles were reports of RCTs including at least one Kaplan-Meier plot. Articles were classified as "assessable" if sufficient information was available to assess LTFU. In these articles, LTFU information was derived from Kaplan-Meier plots, extracted from the text, and compared. Articles were then classified as "consistent" or "not consistent". Sensitivity analyses were performed to assess the validity of study results. Results 319 eligible articles were identified. 187 (59% were classified as "assessable", as they included sufficient information for evaluation; 140 of 319 (44% presented consistent LTFU information between the Kaplan-Meier plot and text. 47 of 319 (15% were classified as "not consistent". These 47 articles were included in sensitivity analyses. When various imputation methods were used, the results of a chi2-test applied to the corresponding 2 × 2 table changed and hence were not robust in about half of the studies. Conclusions Less than half of the articles on RCTs using Kaplan-Meier plots provide assessable and consistent LTFU information, thus questioning the validity of the results and conclusions of many studies presenting survival analyses. Authors should improve the presentation of both Kaplan-Meier plots and LTFU information, and reviewers of study publications and journal editors should critically appraise the validity of the information provided.

    Full Text Available Population density and associated behavioral adjustments are potentially important in regulating physiological performance in many animals. In r-selected species like the fruit fly (Drosophila, where population density rapidly shifts in unpredictable and unstable environments, density-dependent physiological adjustments may aid survival of individuals living in a social environment. Yet, how population density (and associated social behaviors affects physiological functions like metabolism is poorly understood in insects. Additionally, insects often show marked sexual dimorphism (larger females. Thus, in this study on D. melanogaster, we characterized the effects of fly density and sex on both mass-specific routine oxygen consumption (V̇O2 and hypoxia tolerance (PCrit. Females had significantly lower routine V̇O2 (∼4 µl O2 mg−1 h−1 than males (∼6 µl O2 mg−1 h−1 at an average fly density of 28 flies·respirometer chamber−1. However, V̇O2 was inversely related to fly density in males, with V̇O2 ranging from 4 to 11 µl O2 mg−1 h−1 at a density of 10 and 40 flies·chamber−1, respectively (r2=0.58, P0.5 flies, with higher fly densities having a lower PCrit. An extensive survey of the literature on metabolism in fruit flies indicates that not all studies control for, or even report on, fly density and gender, both of which may affect metabolic measurements.

    Highlights: Black-Right-Pointing-Pointer Co or Fe doped TiO{sub 2} thin films were prepared by sol-gel method. Black-Right-Pointing-Pointer We obtained lower E{sub g} values for Fe-doped and Co-TiO{sub 2} thin films. Black-Right-Pointing-Pointer Doping greatly affected the size and shape of the TiO{sub 2} nanoparticles. Black-Right-Pointing-Pointer Photocatalytic killing effect of the doped TiO{sub 2} thin films on C. albicans and A. niger was significantly higher than undoped TiO{sub 2} thin film for short exposure periods. - Abstract: In this study, a short recent literature survey which concentrated on the usage of Fe{sup 3+} or Co{sup 2+} ion doped TiO{sub 2} thin films and suspensions were summarized. Additionally, a sol-gel method was used for preparation of the 2% Co or Fe doped TiO{sub 2} thin films. The surface of the prepared materials was characterised using scanning-electron microscopy (SEM) combined with energy dispersive X-ray (EDX) analysis and band gap of the films were calculated from the transmission measurements that were taken over the range of 190 and 1100 nm. The E{sub g} value was 3.40 eV for the pure TiO{sub 2}, 3.00 eV for the Fe-doped TiO{sub 2} film and 3.25 eV for Co-TiO{sub 2} thin film. Iron or cobalt doping at lower concentration produce more uniformed particles and doping greatly affected the size and shape of the TiO{sub 2} nanoparticles. Photocatalytic killing effect of the 2% Co doped TiO{sub 2} thin film on Candida albicans was significantly higher than Fe doped TiO{sub 2} thin film for short and long exposure periods. Doped thin films were more effective on Aspergillus niger for short exposure periods.

    Full Text Available To enhance research surveying in software methodologies, a model is introduced that can indicate field maturity based on vocabulary and relevant literature. This model is developed by drawing analogies with software methodologies. Two analogies are used: software models and software life cycles or processes. How this model can reduce research surveying problems for researchers is described using extracts from application results as examples. Although the model does support research surveying activities, it cannot choose the subject for the researcher.

    A literature search was conducted by using the Web of Science® Databases component of the ISI Web of KnowledgeSM to identify recent articles that would be useful to help assess the potential environmental effects of renewable energy development in the ocean, with emphasis on marine mammals, seabirds, and fish. Several relatively recent general review articles that included possible effects of marine renewable energy devices on marine mammals and seabirds were examined to begin the search process (e.g., Boehlert et al. 2008; Thompson et al. 2008; Simas et al. 2009). From these articles, several general topics of potential environmental effects on marine mammals, seabirds, and fish were derived. These topics were used as the primary search factors. Searches were conducted with reference to the potential effects of offshore wind farms and MHK devices on marine mammals, seabirds, and fish. Additional sources were identified by cross-checking the Web of Science databases for articles that cited the review articles. It also became clear that often the potential effects were offered as hypotheses that often were not supported by the presentation of appropriate documentation. Therefore, the search was refined and focused on trying to obtain the necessary information to support or challenge a proposed potential effect to a specific concern. One of the expressed concerns regarding MHK devices is that placing wave parks in coastal waters could compromise the migration patterns of whales. Disruption of the annual migration of the gray whale (Eschrichtius robustus), which swims at least 30,000 km on its round trip from breeding grounds in Baja California to feeding areas in the Bering Sea, is of particular concern. Among the hypothesized effects on the migrating gray whales are increased predation risk by constricting migration corridor to between array and shore or by forcing the whales to swim into deeper waters, increased metabolic energy costs and delays in reaching the

    Full Text Available The European Association for the Study of the Liver (EASL criteria and the modified Response Evaluation Criteria in Solid Tumors (mRECIST are currently adopted to evaluate radiological response in patients affected by HCC and treated with loco-regional procedures. Several studies explored the validity of these measurements in predicting survival but definitive data are still lacking.To conduct a systematic review of studies exploring mRECIST and EASL criteria usefulness in predictive radiological response in HCC undergoing loco-regional therapies and their validity in predicting survival.A comprehensive search of the literature was performed in electronic databases EMBASE, MEDLINE, COCHRANE LIBRARY, ASCO conferences and EASL conferences up to June 10, 2014. Our overall search strategy included terms for HCC, mRECIST, and EASL. Loco-regional procedures included transarterial embolization (TAE, transarterial chemoembolization (TACE and cryoablation. Inter-method agreement between EASL and mRECIST was assessed using the k coefficient. For each criteria, overall survival was described in responders vs. non-responders patients, considering all target lesions response.Among 18 initially found publications, 7 reports including 1357 patients were considered eligible. All studies were published as full-text articles. Proportion of responders according to mRECIST and EASL criteria was 62.4% and 61.3%, respectively. In the pooled population, 1286 agreements were observed between the two methods (kappa statistics 0.928, 95% confidence interval 0.912-0.944. HR for overall survival (responders versus non responders according to mRECIST and EASL was 0.39 (95% confidence interval 0.26-0.61, p<0.0001 and 0.38 (95% confidence interval 0.24-0.61, p<0.0001, respectively.In this literature-based meta-analysis, mRECIST and EASL criteria showed very good concordance in HCC patients undergoing loco-regional treatments.

    2016-07-01

    Full Text Available Henna (Lawsonia inermis L. tattooing has been used in Egypt and India since ancient times. Today this temporary body art is becoming increasingly popular among young people. Various chemicals are added to henna to darken and enhance the definition of tattoos, especially para-phenylenediamine (PPD, which is a strong sensitizer known to cause cross sensitive reactions to azoic dyes and other para-amino compounds. We present the case of an 18-year-old girl who became clinically sensitive to textile dyes after having showed a serious reaction both to her first hair dying when she was 16 years old and following the application of a temporary henna tattoo when she was a kid. The evidence from our literature review showed 33 cases of manifest sensitization to hair dye and only one of observable contact allergy to both hair and textile dyes from henna tattoos. The sensitization of children may have long-life lasting consequences, because of cross-reaction to dyes and other chemicals contained in hair colourants, clothes and drugs. Since tattoos are very popular and globalization has increased the circulation of unauthorized products we point out the need for informative campaigns about the risk of sensitization caused by temporary tattoos.

  8. War in Colombia testimonial literature: between memory, culture, violence and literature

    Directory of Open Access Journals (Sweden)

    Jorge Eduardo Suárez Gómez

    2011-07-01

    Full Text Available Colombia may be characterized as a society ruled over by “a routinization of war and oblivion”. When memories about violent events succeed in articulate themselves and transcend the private space, they are not necessarily incorporated to national memory through “memory policies” in transitional processes. These memories are “deposited” rather than discussed. Testimonial literature is one of those “deposits”. There are times when certain topics, witnesses, authors and narrative treatments attain an unexpected relevance. Such a relevance follows national factors, like the dynamics of conflict and society in Colombia and abroad, such as a “turn to past”. When making a survey across the development of the testimonial genre from mid-20th century Violence up to our times, the gravitation of several cultures of memory is made evident in a society where oblivion appears to prevail.

    Among the various modes of death due to asphyxiation, drowning is unique. Unlike other types of suffocation associated with occluding airway obstructions (i.e. choking and smothering); with drowning, there is typically filling and involvement of the majority of the tracheobronchial tree and aerodigstive tract. Although the usual drowning medium is water, it can also occur in other media. Moreover, although drowning sometimes occurs in the setting of a motor vehicle accident, an element of vehicular submersion or immersion is usually operative in such instances. The case presented here is that of a motor vehicle crash which resulted in drowning where no immersion of the vehicle occurred. Moreover, the drowning medium was paraffin wax, rather than water. Other cases in the literature of drowning in atypical media and also those which are reported in the concomitant presence of a motor vehicle accident are presented.

    The aetiology of suicide is complex and still not completely understood. The present communication, which consists of two parts, aims to shed some light on the role of amino acidergic neurotransmission in suicide. In the first part we provide an overview of the literature showing that with the exception of certain gamma-aminobutyric acid transporters, virtually all components of the glutamate-glutamine- gamma-aminobutyric acid cycle are, in some way or other, abnormal in suicide victims, which indicates a prominent involvement of the glutamatergic and gammaaminobutyric acidergic neurotransmitter systems in suicidal behaviour. In the second part we present own immunohistochemical findings showing that densities of glutamine synthetase expressing glial cells in the mediodorsal thalamus as well as in the dorsolateral prefrontal and orbitofrontal cortex of schizophrenic suicide completers are significantly elevated compared with controls and non-suicide individuals with schizophrenia, thus calling into question the belief that cerebral glutamine synthetase deficit is indicative of suicidal behaviour.

    Prior studies have identified a consensus amongst climate science experts regarding anthropogenic global warming (AGW) as outlined by the Intergovernmental Panel on Climate Change (Oreskes 2004). Despite this evidence, a poll of 1010 American adults (Leiserowitz et al. 2011) revealed that only 15% believed that a large majority (>81%) of climate scientists think that global warming is caused mostly by human activities. This lack of public awareness of the consensus has hindered the implementation of climate policy, in the United States in particular. Using an online abstract classification and rating system in combination with an email survey of the papers' authors, a team of 24 contributors to the weblog Skeptical Science undertook an analysis of 12,465 abstracts published between 1991 and 2011, listed in the Web of Science with the keywords "global warming" and/or "global climate change". Each abstract was reviewed independently at least twice, based on the abstract and the title, with no reference to the authorship. This study represents the single largest survey of peer-reviewed climate research, and the large sample size allows for identification of patterns in climate research over time. Abstracts were classified based on subject focus, using a set of written criteria, as one of "impacts", "methods", "mitigation", "paleoclimate", or "opinion"; and rated according to degree of endorsement or rejection of AGW: three categories each of explicit/implicit endorsement and rejection, and a neutral category. Abstracts that referred to a changing climate but did not assert or reject a linkage to human-produced greenhouse gases were rated "neutral", and this rating proved to be by far the most common, comprising approximately 67% of total abstracts. Endorsement categories made up approximately 33% of all abstracts examined, whereas those rejecting AGW comprised less than 1%. Overall, endorsements outnumbered rejections approximately 50-to-1, consistent with the 97

    2005-01-01

    This paper investigates how the phenomenon of fuzzy language, such as `many' in `Mary has many friends', can be explained by Relevance Theory. It is concluded that fuzzy language use conforms with optimal relevance in that it can achieve the greatest positive effect with the least processing effort. It is the communicators themselves who decide whether or not optimal relevance is achieved, rather than the language form (fuzzy or non-fuzzy) used. People can skillfully adjust the deployment of different language forms or choose appropriate interpretations to suit different situations and communication needs. However, there are two challenges to RT: a. to extend its theory from individual relevance to group relevance; b. to embrace cultural considerations (because when relevance principles and cultural protocols are in conflict, the latter tends to prevail).

According to relevance theory, communication not only requires encoding, transfer and decoding processes, but also involves inference in addition. As communication, translation decision-making is also based on the human beings' inferential mental faculty. Concentrating on relevance theory, this paper tries to analyze and explain some translation phenomena in two English versions of Cai Gen Tan-My Crude Philosophy of Life.

    Since the 1970s of the 20th century,the social sciences and humanities of the West have several theoretical transformations and made some breakthroughs in the disciplinary confinement in terms of aesthetics,human geography,iconology and literature.As a result,the “landscape”studies have developed into three branches with a comprehensive knowledge framework,landscape studies, place studies and ecocriticism,which are seemingly independent but in fact are inter-disciplinary and inter-beneficial.Topophilia:A Study of Environmental Perception,Attitudes and Values,Social Formation And Symbolic Landscape,Landscape and Power and Landscape and Memory are the four landmarks and constitute the core concepts of landscape studies.More importantly,they have paved a disciplinary approach to landscape &literature,with a focus on “interpreting culture in terms of landscape and interpreting landscape in terms of culture”.Thus,researches keep going along the academic orientation of landscape-psychology-symbolism-power/medium-memory-identity,and gradu-ally get into the interdisciplinary studies involving the literature of post-colonialism and feminism as well as urban studies.%20世纪70年代以来,西方人文社科学界的几次理论转向,突破了美学、人文地理学、图像学、文学批评等固守或特取的研究对象和范型,使得围绕“风景”所展开的研究逐渐形成庞大的知识谱系,并分蘖出三支貌似独立、但可互相挪用,时与文艺理论互惠的学科:风景学、地方研究和生态批评。风景学的四部著述堪称地标之作———《恋地情结:对环境感知、态度和价值的研究》、《社会构成与象征的风景》、《风景与权力》和《风景与记忆》联合完成了风景研究核心概念体系。更重要的是,在开拓“从风景思考文化,从文化思考风景”研究主路同时,还铺设了一条重要支线———风景与文学。受其启发不断跟

    Helicopter EMS (HEMS) and its possible association with outcomes improvement continues to be a subject of discussion. As is the case with other scientific discourse, debate over HEMS usefulness should be framed around an evidence-based assessment of the relevant literature. In an effort to facilitate the academic pursuit of assessment of HEMS utility, in late 2000 the National Association of EMS Physicians' (NAEMSP) Air Medical Task Force prepared annotated bibliographies of the HEMS-related outcomes literature. As a result of that work, two review articles, one covering HEMS use in nontrauma and the other in trauma, published in 2002 in Prehospital Emergency Care surveyed HEMS outcomes-related literature published between 1980 and mid-2000. The project was extended with two subsequent reviews covering the literature through 2006. This review continues the series, outlining outcomes-associated HEMS literature for the three-year period 2007 through the first half of 2011.

    Scientific software plays an important role in critical decision making, for example making weather predictions based on climate models, and computation of evidence for research publications. Recently, scientists have had to retract publications due to errors caused by software faults. Systematic testing can identify such faults in code. This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. We found that challenges faced when testing scientific software fall into two main categories: (1) testing challenges that occur due to characteristics of scientific software such as oracle problems and (2) testing challenges that occur due to cultural differences between scientists and the software engineering community such as viewing the code and the model that it implements as inseparable entities. In addition, we identified methods to potentially overcome these challenges and their limitations. Finally we describe unsolved challenges and how software engineering researchers and practitioners can help to overcome them. Scientific software presents special challenges for testing. Specifically, cultural differences between scientist developers and software engineers, along with the characteristics of the scientific software make testing more difficult. Existing techniques such as code clone detection can help to improve the testing process. Software engineers should consider special challenges posed by scientific software such as oracle problems when developing testing techniques.

    To assess the impact of using "grey literature" (information internally produced in print or electronic format by agencies such as hospitals, government, businesses, etc) rather than a textbook in a course on healthcare delivery systems on students' perception of the relevance of healthcare delivery system topics and their ability to identify credible sources of this information. A reading from the grey literature was identified and assigned to the students for each topic in the course. Pre- and post-course survey instruments were used for the assessment. Students reported healthcare delivery systems topics to be moderately relevant to the profession of pharmacy on both the pre- and post-course survey instruments. Students' knowledge of current and credible sources of information on healthcare delivery system topics significantly improved based on self-reports and scores on objective assessments (phealthcare delivery systems can be used to ensure that information in the pharmacy school curriculum is the most current and credible information available.

    Squamous cell carcinoma (SCC) is a common skin cancer that poses a risk of metastasis. Clinical investigations into SCC treatment are common, but the outcomes reported are highly variable, omitted, or clinically irrelevant. The outcome heterogeneity and reporting bias of these studies leave clinicians unable to accurately compare studies. Core outcome sets (COSs) are an agreed minimum set of outcomes recommended to be measured and reported in all clinical trials of a given condition or disease. Although COSs are under development for several dermatologic conditions, work has yet to be done to identify core outcomes specific for SCC. Outcome extraction for COS generation will occur via four methods: (1) systematic literature review; (2) patient interviews; (3) other published sources; and (4) input from stakeholders in medicine, pharmacy, and other relevant industries. The list of outcomes will be revaluated by the Measuring PRiority Outcome Variables via Excellence in Dermatologic surgery (IMPROVED) Steering Committee. Delphi processes will be performed separately by expert clinicians and patients to condense the list of outcomes generated. A consensus meeting with relevant stakeholders will be conducted after the Delphi exercise to further select outcomes, taking into account participant scores. At the end of the meeting, members will vote and decide on a final recommended set of core outcomes. The Core Outcome Measures in Effectiveness Trials (COMET) organization and the Cochrane Skin Group - Core Outcome Set Initiative (CSG-COUSIN) will serve as advisers throughout the COS generation process. Comparison of clinical trials via systematic reviews and meta-analyses is facilitated when investigators study outcomes that are relevant and similar. The aim of this project is to develop a COS to guide use for future clinical trials.

    Facial aging is a concern for many patients. Wrinkles, loss of volume, and discoloration are common physical manifestations of aging skin. Genetic heritage, prior ultraviolet light exposure, and Fitzpatrick skin type may be associated with the rate and type of facial aging. Although many clinical trials assess the correlates of skin aging, there is heterogeneity in the outcomes assessed, which limits the quality of evaluation and comparison of treatment modalities. To address the inconsistency in outcomes, in this project we will develop a core set of outcomes that are to be evaluated in all clinical trials relevant to facial aging. A long list of measureable outcomes will be created from four sources: (1) systematic medical literature review, (2) patient interviews, (3) other published sources, and (4) stakeholder involvement. Two rounds of Delphi processes with homogeneous groups of physicians and patients will be performed to prioritize and condense the list. At a consensus meeting attended by physicians, patients, and stakeholders, outcomes will be further condensed on the basis of participant scores. By the end of the meeting, members will vote and decide on a final recommended set of core outcomes. Subsequent to this, specific measures will be selected or created to assess these outcomes. The aim of this study is to develop a core outcome set and relevant measures for clinical trials relevant to facial aging. We hope to improve the reliability and consistency of outcome reporting of skin aging, thereby enabling improved evaluation of treatment efficacy and patient satisfaction.

    Full Text Available Serum albumin is one of the most widely studied proteins. It is the most abundant protein in plasma with a typical concentration of 5 g/100 mL and the principal transporter of fatty acids in plasma. While the crystal structures of human serum albumin (HSA free and in complex with fatty acids, hemin, and local anesthetics have been characterized, no crystallographic models are available on bovine serum albumin (BSA, presumably because of the poor diffraction power of existing hexagonal BSA crystals. Here, the crystallization and diffraction data of a new BSA crystal form, obtained by the hanging drop method using MPEG 5K as precipitating agent, are presented. The crystals belong to space group C2, with unit-cell parameters a = 216.45 Å, b = 44.72 Å, c = 140.18 Å, β = 114.5°. Dehydration was found to increase the diffraction limit of BSA crystals from ~8 Å to 3.2 Å, probably by improving the packing of protein molecules in the crystal lattice. These results, together with a survey of more than 60 successful cases of protein crystal dehydration, confirm that it can be a useful procedure to be used in initial screening as a method of improving the diffraction limits of existing crystals.

    To conduct (1) a systematic survey of the reporting quality of simulation studies dealing with how to handle missing participant data (MPD) in randomized control trials and (2) summarize the findings of these studies. We included simulation studies comparing statistical methods dealing with continuous MPD in randomized controlled trials addressing bias, precision, coverage, accuracy, power, type-I error, and overall ranking. For the reporting of simulation studies, we adapted previously developed criteria for reporting quality and applied them to eligible studies. Of 16,446 identified citations, the 60 eligible generally had important limitations in reporting, particularly in reporting simulation procedures. Of the 60 studies, 47 addressed ignorable and 32 addressed nonignorable data. For ignorable missing data, mixed model was most frequently the best on overall ranking (9 times best, 34.6% of times tested) and bias (10, 55.6%). Multiple imputation was also performed well. For nonignorable data, mixed model was most frequently the best on overall ranking (7, 46.7%) and bias (8, 57.1%). Mixed model performance varied on other criteria. Last observation carried forward (LOCF) was very seldom the best performing, and for nonignorable MPD frequently the worst. Simulation studies addressing methods to deal with MPD suffered from serious limitations. The mixed model approach was superior to other methods in terms of overall performance and bias. LOCF performed worst. Copyright © 2017 Elsevier Inc. All rights reserved.

    The aim of the present literature study has been to collect knowledge about reported concentrations of chloride concentrations in concrete exposed to brackish water and also to get an overview of whether a critical threshold chloride concentration for chloride induced corrosion on steel embedded in concrete has been reported and/or accepted. Only five known reports present chloride concentrations in concrete that has been exposed to brackish water. All three refer to the Baltic sea or the Gulf of Bothnia. Reported chloride concentrations in the concrete is considerably higher (more than a factor of ten) than what would have been expected if the chloride had been present in the concrete only as sea water in the pore system. One reason why high chloride concentrations occur in certain zones of the concrete may be that in these zones, evaporation and capillary suction of salt water may occur alternately. Another reason is that chloride ions are physically and/or chemically bound to the cement paste structure. Chloride binding is reported to be dependent on pH value in the pore solution. In line with this, another report suggests that the pH value of the outer chloride solution (the exposure solution) may be affected by the test sample when tests are carried out in small beakers, like in the laboratory. The author of that report says this might be a reason why critical chloride concentrations with respect to steel corrosion measured in the laboratory and in the field will deviate. As for reported threshold levels, many different values have been reported, differing by more than a factor 100, irrespective of the way of reporting (chloride by cement weight, chloride to hydroxide ratio, chloride to pore solution volume, etc). Some authors claim that in fact no one, single critical chloride concentration exists, but that it will depend on several other factors such as humidity, oxygen availability, pH etc. Furthermore, there are different opinions on whether bound

    In the working hypothesis we assumed that the procoagulant activity of microparticles (MPs) is associated with the concentration of tissue factor (TF) and its inhibitor (TFPI), and that these three components together affect fetal hemostasis. The aim of the study was to check whether MPs are present in the cord blood, to compare their concentration with that in the maternal blood, as well as to measure the concentrations of TF antigen and TFPI antigen in the cord blood and maternal blood. The study group consisted of 28 healthy parturient women who gave normal delivery, and their 28 babies. Blood from the umbilical vein was collected immediately after delivery, still prior to omphalotomy, whereas mother's blood was obtained from the antecubital vein. The concentration of MPs as well as TF antigen and TFPI antigen were measured using ELISA method. The level of MPs in cord blood plasma was found to be 6.25 times higher than in the mother's blood plasma (median: 26.76 nM PS; range: 22.90-34.41 nM PS vs. median: 4.26 nM PS; range: 2.68-5.37 nM PS respectively, p=0.0022), whereas the level of TF antigen was 1.94 times higher in the fetus than in the mother (median: 238.03 pg/ml; range: 192.25-283.10 pg/ml vs. median: 122.4 pg/ml, range: 52.71-176.74 pg/ml, respectively, p=0.0012). On the other hand, the level of TFPI antigen was lower in cord blood plasma than in maternal blood plasma, accounting for 33.95% of the value noted in the mother (median: 30.04 ng/ml, range: 24.84-35.12 ng/ml vs. median: 88.48 ng/ml; range: 78.64-107.20 ng/ml, respectively, pMPs) are constituent components of cord blood plasma; their concentration is significantly higher than that in mother's blood plasma. In the fetus, MPs may play a role of a powerful procoagulant, thus facilitating thrombin generation (TF-dependent thrombin generation, which may take place on their surface); this hypothesis is based on literature data and our own evidence.

    This paper reports the estimates concerning the atmospheric carbon dioxide absorption and storage by living plants all over the world. It is necessary to decrease atmospheric carbon dioxide concentrations for avoiding global warming. As living plants absorb carbon dioxide by photosynthesis and accumulate carbon in their bodies, they can play an important role to remove atmospheric carbon dioxide. Literatures describing distribution areas, biomass values and net primary productivity (NPP) of forests, marine plants and microorganisms were collected. Examining those data, the biomass and NPP of forests, marine plants and microorganisms can be summarized as follows: (1) Forest biomass and their NPP of the world. The world's forest area is recently estimated as 4 billion hectares, and their biomass is about 400 billion tons of carbon which is equal to 2/3 of the total atmospheric carbon. The NPP of the world's forest is estimated as 25-35 billion tons C/year. (2) Mean biomass and NPP of forest communities. The mean biomass and NPP were calculated for dozens of forest communities in tropical/sub-tropical, warm-temperature, cool-temperate and boreal zones. The forest mean biomass ranges from 20 to 200 tons C/ha except for the high values of Sequoia and Tsuga forest. The forest biomass in warm-temperature is smaller than the corresponding values in the other climate zones. The mean NPP ranged from 3 to 10 tons C/ha/year except for the high values of several tropical artificial forests. (3) Marine plant biomass and NPP. The biomass and NPP of the world's marine plants are 0.3-1.5 billion tons C and 10-40 billion tons C/year respectively. These values suggest that marine plants perform an important function in carbon fixation, but have a small storage. (4) Microorganism biomass and NPP. The world's microorganisms are small in biomass, but some species have high photosynthetic ability.

    In China, the field of orthopedics has experienced significant growth over the past 12 years. However, the recent status of research on orthopedics among individuals in mainland China, Hong Kong, and Taiwan is unknown. In this study, we investigated characteristics and trends of orthopedics publications from these three regions. Between 2003 and 2014, all articles published in 63 orthopedics journals originating from mainland China, Hong Kong, and Taiwan were identified via Science Citation Index Expanded (SCIE) database. A survey was conducted to systematically analyze the published orthopedics articles from the three regions according to the numbers of articles, study design, impact factors (IFs), citations, most prolific authors, and institutions. Additionally, we evaluated global trends in orthopedics publications, and ranked top 10 countries in terms of the total number of published articles over 12 years and the number of published articles per year. A total number of 123,317 articles were published in the 63 orthopedics journals between 2003 and 2014. The worldwide number of annually published orthopedics articles tended to increase during the study period. The total number of orthopedics publications from the three regions, especially in mainland China, increased markedly from 2003 to 2014. The annual number of orthopedics articles from mainland China increased from 6 in 2003 to 813 in 2014, Hong Kong increased from 32 in 2003 to 71 in 2014, and Taiwan increased from 68 in 2003 to 168 in 2014. For accumulated IFs and total citations of articles, mainland China ranked the first place, followed by Taiwan and Hong Kong. However, publications from Taiwan had the highest average citations per article, and publications from Hong Kong had the highest average IFs. Among the top 10 most prolific authors and institutions, 4 authors and 4 institutions were from Taiwan, 3 authors and 4 institutions were from mainland China, and 3 authors and 2 institutions were from

  17. Passage relevance models for genomics search

    2009-03-01

    Full Text Available Abstract We present a passage relevance model for integrating syntactic and semantic evidence of biomedical concepts and topics using a probabilistic graphical model. Component models of topics, concepts, terms, and document are represented as potential functions within a Markov Random Field. The probability of a passage being relevant to a biologist's information need is represented as the joint distribution across all potential functions. Relevance model feedback of top ranked passages is used to improve distributional estimates of query concepts and topics in context, and a dimensional indexing strategy is used for efficient aggregation of concept and term statistics. By integrating multiple sources of evidence including dependencies between topics, concepts, and terms, we seek to improve genomics literature passage retrieval precision. Using this model, we are able to demonstrate statistically significant improvements in retrieval precision using a large genomics literature corpus.

    Noma (cancrum oris) is an orofacial gangrene, which during its fulminating course causes progressive and mutilating destruction of the infected tissues. The disease occurs mainly in children with malnutrition, poor oral hygiene and debilitating concurrent illness. Noma is well documented in the literature, but because most patients do not report to a doctor until the disease is at an advanced stage, its onset and progression remain a mystery. This case report, with a survey of recent relevant literature, highlights the different stages in the development of tissue necrosis, including onset and progression, with an emphasis on the need for early diagnosis and prompt treatment.

  8. The Limits to Relevance

    Science.gov (United States)

    Averill, M.; Briggle, A.

    2006-12-01

    Science policy and knowledge production lately have taken a pragmatic turn. Funding agencies increasingly are requiring scientists to explain the relevance of their work to society. This stems in part from mounting critiques of the "linear model" of knowledge production in which scientists operating according to their own interests or disciplinary standards are presumed to automatically produce knowledge that is of relevance outside of their narrow communities. Many contend that funded scientific research should be linked more directly to societal goals, which implies a shift in the kind of research that will be funded. While both authors support the concept of useful science, we question the exact meaning of "relevance" and the wisdom of allowing it to control research agendas. We hope to contribute to the conversation by thinking more critically about the meaning and limits of the term "relevance" and the trade-offs implicit in a narrow utilitarian approach. The paper will consider which interests tend to be privileged by an emphasis on relevance and address issues such as whose goals ought to be pursued and why, and who gets to decide. We will consider how relevance, narrowly construed, may actually limit the ultimate utility of scientific research. The paper also will reflect on the worthiness of research goals themselves and their relationship to a broader view of what it means to be human and to live in society. Just as there is more to being human than the pragmatic demands of daily life, there is more at issue with knowledge production than finding the most efficient ways to satisfy consumer preferences or fix near-term policy problems. We will conclude by calling for a balanced approach to funding research that addresses society's most pressing needs but also supports innovative research with less immediately apparent application.

  10. A Critical Review of Surveys Emphasizing on Routing in Wireless Sensor Networks—An Anatomization under General Survey Design Framework

    Science.gov (United States)

    2017-01-01

    A large number of routing-related surveys are published so far for Wireless Sensor Networks (WSNs) that exhibit either complete or partial emphasis on routing in WSNs. These surveys classify and discuss the relevant routing protocols published mainly in the fields of classical, energy efficient, secure, hierarchical, geographic, intelligent, Quality of Service (QoS)-based and multipath WSNs. However, to the best of our knowledge, no study is presented so far which may clearly categorize the routing-related survey literature for WSNs.To fill this gap, an effort is made in this paper for presenting an in-depth review of already published routing-related survey literature in WSNs. Our review initially proposes a generalized survey design model and afterwards analyzes the routing-related survey literature in the light of the devised General Survey Design Framework (GSDF). Such an analysis describes the design soundness of the published routing-related surveys. Therefore, our review puts forth an original classification based on the frequency-of-survey-publication and taxonomizes the corresponding routing-related fields into high, medium and low focused areas of survey publication in WSNs. Furthermore, the surveys belonging to each main category are sub-categorized into various sub-classes and briefly discussed according to their design characteristics. On the one hand, this review is useful for beginners who may easily explore the already published routing-related survey literature in WSNs in a single document and investigate it by spending less effort. On the other hand, it is useful for expert researchers who may explore the trends and frequency of writing surveys in different areas of routing in WSNs. The experts may explore those areas of routing which are either neglected or least focused or lack in design soundness as per general survey design framework. In the end, insights and future research directions are outlined and a reasonable conclusion is put forth

    2013-03-01

    Typical engineering methods utilized to calculate stresses on a roof structure involve simplifying assumptions that render a complex non-linear structure a simple and basic determinate beam. That is, instead of considering the composite action of the entire roof structure, the engineer evaluates only a single beam that is deemed conservatively to represent an affected rafter or top chord of a truss. This simplification based on assumptions of a complex problem is where significant conservatism can be introduced. Empirical data will be developed to evaluate this issue. Simple wood beams will be tested to failure. More complex and complete sections of roof structures that include composite action will also be tested to failure. The results can then be compared. An initial step in this process involves a literature review of any work that has been performed on roof structure composite action. The following section summarizes the literature review that was completed.

    Full Text Available Physical barriers may hamper persons with disabilities (PWDs movement in built environment. The needs of physical barrier- free environment are internationally acknowledged. This study explores the Malaysian scenario on access and facilities for PWDs by reviewing relevant legislation and guidelines, and literatures that examined the access and facilities provided in public buildings. This study identifies that Malaysia has plays its roles by establishing the relevant acts and legislation on PWDs needs and requirements. Nevertheless, previous studies on PWDs in Malaysia, demonstrated that there are still lacking on the implementation of the practice towards the acts and legislations. This study suggests that the application of the acts and legislation should be comprehensive covering all types of public buildings in Malaysia. In addition, enforcement by the local authorities and government agencies is crucial in order to successfully creating a barrier-free environment for all.

  16. Another Look at Confidence Intervals: Proposal for a More Relevant and Transparent Approach

    CERN Document Server

    Biller, Steven D

    2014-01-01

    The behaviors of various confidence/credible interval constructions are explored, particularly in the region of low statistics where methods diverge most. We highlight a number of challenges, such as the treatment of nuisance parameters, and common misconceptions associated with such constructions. An informal survey of the literature suggests that confidence intervals are not always defined in relevant ways and are too often misinterpreted and/or misapplied. This can lead to seemingly paradoxical behaviours and flawed comparisons regarding the relevance of experimental results. We therefore conclude that there is a need for a more pragmatic strategy which recognizes that, while it is critical to objectively convey the information content of the data, there is also a strong desire to derive bounds on models and a natural instinct to interpret things this way. Accordingly, we attempt to put aside philosophical biases in favor of a practical view to propose a more transparent and self-consistent approach that b...

    Poverty is widespread and significant in developing countries. As world poverty expands and the gap between rich and poor widens, advocates increasingly support development policies designed to help the poor meet basic needs. Policies generally followed since the second World War have contributed to GNP growth but fail to reduce income inequalities and noticeably improve life for the poor. This paper discusses the evolution of basic needs as a concept and policy goal, the conflict between basic needs and growth, the impact of basic needs on population and popular participation, and results of empirical studies. Basic needs policies may be humanitarian, but evidence supports neither their ability to promote growth, control population, nor encourage popular participation. Basic needs policies are nonetheless noble and challenge us to face poverty as a universal problem.

    Full Text Available The incidence of obesity has increased dramatically during recent decades. Obesity increases the risk for metabolic and cardiovascular diseases and may therefore contribute to premature death. With increasing fat mass, secretion of adipose tissue derived bioactive molecules (adipokines changes towards a pro-inflammatory, diabetogenic and atherogenic pattern. Adipokines are involved in the regulation of appetite and satiety, energy expenditure, activity, endothelial function, hemostasis, blood pressure, insulin sensitivity, energy metabolism in insulin sensitive tissues, adipogenesis, fat distribution and insulin secretion in pancreatic β-cells. Therefore, adipokines are clinically relevant as biomarkers for fat distribution, adipose tissue function, liver fat content, insulin sensitivity, chronic inflammation and have the potential for future pharmacological treatment strategies for obesity and its related diseases. This review focuses on the clinical relevance of selected adipokines as markers or predictors of obesity related diseases and as potential therapeutic tools or targets in metabolic and cardiovascular diseases.

  12. Scientists Admitting to Plagiarism: A Meta-analysis of Surveys.

    Science.gov (United States)

    Pupovac, Vanja; Fanelli, Daniele

    2015-10-01

    We conducted a systematic review and meta-analysis of anonymous surveys asking scientists whether they ever committed various forms of plagiarism. From May to December 2011 we searched 35 bibliographic databases, five grey literature databases and hand searched nine journals for potentially relevant studies. We included surveys that asked scientists if, in a given recall period, they had committed or knew of a colleague who committed plagiarism, and from each survey extracted the proportion of those who reported at least one case. Studies that focused on academic (i.e. student) plagiarism were excluded. Literature searches returned 12,460 titles from which 17 relevant survey studies were identified. Meta-analysis of studies reporting committed (N = 7) and witnessed (N = 11) plagiarism yielded a pooled estimate of, respectively, 1.7% (95% CI 1.2-2.4) and 30% (95% CI 17-46). Basic methodological factors, including sample size, year of survey, delivery method and whether survey questions were explicit rather than indirect made a significant difference on survey results. Even after controlling for these methodological factors, between-study differences in admission rates were significantly above those expected by sampling error alone and remained largely unexplained. Despite several limitations of the data and of this meta-analysis, we draw three robust conclusions: (1) The rate at which scientists report knowing a colleague who committed plagiarism is higher than for data fabrication and falsification; (2) The rate at which scientists report knowing a colleague who committed plagiarism is correlated to that of fabrication and falsification; (3) The rate at which scientists admit having committed either form of misconduct (i.e. fabrication, falsification and plagiarism) in surveys has declined over time.

    The single transition ions in various crystals or molecules as well as the exchange coupled systems (ECS) of transition ions, especially the single molecule magnets (SMM) or molecular nanomagnets (MNM), have been extensively studied in recent decades using electron magnetic resonance (EMR), optical spectroscopy, and magnetic measurements. Interpretation of magnetic and spectroscopic properties of transition ions is based on two physically distinct types of Hamiltonians: the physical crystal field (CF), or equivalently ligand field (LF), Hamiltonians and the effective spin Hamiltonians (SH), which include the zero-field splitting (ZFS) Hamiltonians. Survey of recent literature has revealed a number of terminological confusions and specific problems occurring at the interface between these Hamiltonians (denoted CF (LF)↔SH (ZFS)). Elucidation of sloppy or incorrect usage of crucial notions, especially those describing or parameterizing crystal fields and zero field splittings, is a very challenging task that requires several reviews. Here we focus on the prevailing confusion between the CF (LF) and SH (ZFS) quantities, denoted as the CF=ZFS confusion, which consists in referring to the parameters (or Hamiltonians), which are the true ZFS (or SH) quantities, as purportedly the CF (LF) quantities. The inverse ZFS=CF confusion, which pertains to the cases of labeling the true CF (LF) quantities as purportedly the ZFS quantities, is considered in a follow-up paper. The two reviews prepare grounds for a systematization of nomenclature aimed at bringing order to the zoo of different Hamiltonians. Specific cases of the CF=ZFS confusion identified in the recent textbooks, review articles, and SMM (MNM)- and EMR-related papers are surveyed and the pertinent misconceptions are outlined. The consequences of the terminological confusions go far beyond simple semantic issues or misleading keyword classifications of papers in journals and scientific databases. Serious

  16. Teaching Skills through Literature

    Full Text Available This study tries to investigate the contributory factors in the success and failure in teaching of the four language skills through teaching of literature because literature is critically and crucially relevant to the evolution of a literary sensibility. The basic end of literature is to read which develops reading skills and to reinterpret the dynamics of a given society. In this process the language skills are actually manifested. Literature, if we deconstruct the term involves two stages of reading; one that is the text, and second; the subsequent evaluation which entails the ability to break the text and trace the possibilities of meanings. This cannot be done without a proper perspective of the literary and linguistic mind, and the very act of interpretation amply appropriates reading skills. Literature fundamentally helps to develop the spirit of inquiry and the variety of thoughts involved in the representation of the text and; therefore, the study of literature enhances the ability to think beyond what you have been provided with and also to be equipped with a quizzical bent of mind that seeks to establish the competence to question what is read as a matter of literary text. This makes the learner naturally acquire the language from the literary context and consequently develop the language skills. Teaching of language through literature has been a tested method as literary texts are so complete with vocabulary, the terrain of thoughts, the diversity of human encounters and the complexity of experiences. In the process of deconstructing a text, one comes across umpteen shades of thoughts conceived and delivered in a compressed form. Also the decoding of the language given its symbolic structure greatly enhances the prospects of independent thinking and writing. In this way the written skills are widely developed. A text is a bundle of thoughts clad in a complicated web of linguistic sophistication, and the sophistry alone suffices to

    Despite the knowledge concerning the pathogenesis of tuberculosis, this disease remains one of the most important causes of mortality worldwide. Several risk factors are well-known, such poverty, HIV infection, and poor nutrition, among others. However, some issues that may influence tuberculosis warrant further investigation. In particular, the chronobiological aspects related to tuberculosis have garnered limited attention. In general, the interface between tuberculosis and chronobiology is manifested in four ways: variations in vitamin D bioavailability, winter conditions, associated infections, and circannual oscillations of lymphocytes activity. Moreover, tuberculosis is related to the following chronobiological factors: seasonality, latitude, photoperiod and radiation. Despite the relevance of these topics, the relationship between them has been weakly reviewed. This review aims to synthesize the studies regarding the association between tuberculosis and chronobiology, as well as urge critical discussion and highlight its applicability to health policies for tuberculosis.

She examines the position of such informant, in the light of what she calls the "axiomatics of imperialism" in Brontë's Jane Eyre, in Rhys' Wide Sargasso Sea, and in Shelley's Frankenstein, to end up with a reading of Mahasweta Devi's "Pterodactyl, Puran Sahay and Pirtha".

    This study considers the extent to which users with the same query agree as to what is relevant, and how what is considered relevant may translate into a retrieval algorithm and results display. To combine user perceptions of relevance with algorithm rank and to present results, we created a prototype digital library of scholarly literature. We confine studies to one population of scientists (paleontologists), one domain of scholarly scientific articles (paleo-related), and a prototype system (PaleoLit) that we built for the purpose. Based on the principle that users do not pre-suppose answers to a given query but that they will recognize what they want when they see it, our system uses a rules-based algorithm to cluster results into fuzzy categories with three relevance levels. Our system matches at least 1/3 of our participants' relevancy ratings 87% of the time. Our subsequent usability study found that participants trusted our uncertainty labels but did not value our color-coded horizontal results layout ...

  7. Noise at night in hospital general wards: a mapping of the literature.

    Science.gov (United States)

    Fillary, Julie; Chaplin, Hema; Jones, Gill; Thompson, Angela; Holme, Anita; Wilson, Patricia

    English NHS inpatient surveys consistently identify that noise at night in hospitals and its impact on patients' sleep is a persisting problem that needs addressing. To identify how noise at night in hospital affects patients on general wards and the range of interventions aimed at reducing the problem, a systematic mapping of the literature was undertaken. All primary studies and relevant literature published January 2003-July 2013 were included. Key issues identified in the literature included noise levels and causes, impact on patient experience, and lack of staff awareness. Interventions to reduce noise were targeted at staff education, behaviour modification, care organisation and environmental solutions. The scoping suggested that when compared with specialist units, there is little evidence on effective interventions reducing disturbance from night-time noise on general wards. The available evidence suggests a whole systems approach should be adopted to aid quality sleep and promote recovery.

    Full Text Available Background The constantly growing publication rate of medical research articles puts increasing pressure on medical specialists who need to be aware of the recent developments in their field. The currently used literature retrieval systems allow researchers to find specific papers; however the search task is still repetitive and time-consuming. Aims In this paper we describe a system that retrieves medical publications by automatically generating queries based on data from an electronic patient record. This allows the doctor to focus on medical issues and provide an improved service to the patient, with higher confidence that it is underpinned by current research. Method Our research prototype automatically generates query terms based on the patient record and adds weight factors for each term. Currently the patient’s age is taken into account with a fuzzy logic derived weight, and terms describing blood-related anomalies are derived from recent blood test results. Conditionally selected homonyms are used for query expansion. The query retrieves matching records from a local index of PubMed publications and displays results in descending relevance for the given patient. Recent publications are clearly highlighted for instant recognition by the researcher. Results Nine medical specialists from the Royal Adelaide Hospital evaluated the system and submitted pre-trial and post-trial questionnaires. Throughout the study we received positive feedback as doctors felt the support provided by the prototype was useful, and which they would like to use in their daily routine. Conclusion By supporting the time-consuming task of query formulation and iterative modification as well as by presenting the search results in order of relevance for the specific patient, literature retrieval becomes part of the daily workflow of busy professionals.

The authors performed a retrospective review of cases of otosclerosis diagnosed in their institution by means of high resolution multidetector computed tomography. Otosclerosis corresponds to otic capsule dysplasia characterized by metabolic derangement of its endochondral layer. Such condition constitutes a relevant cause of sensorineural hearing loss, affecting about 7% to 10% of the general population. The diagnosis is usually clinical, but imaging methods play a significant role in the anatomical detailing, differential diagnosis, surgical planning and evaluation of postoperative complications. Among such methods, the relevance of MDCT is highlighted. Radiologists should be familiar with the MDCT findings of otosclerosis, as well as with the temporal bone anatomy to assist in the appropriate clinical management of this disease.

    2016-08-01

    Anecdotal experiences raise concerns that abusive head trauma (AHT) is significantly underdiagnosed and perhaps poorly recognized in Latin American settings. With increasing interest in international collaboration in pediatrics, differences in perspectives regarding complex diagnoses should be explored to facilitate a productive exchange of knowledge and ideas. The purpose of this study was to describe the medical literature pertaining to AHT available to physicians who read only in Spanish. In this review, LILACS, SciELO (major Spanish language databases) and Pubmed were searched with appropriate terms and filters in English, Spanish, and Portuguese for Spanish language articles on AHT. Identified articles' reference lists were then examined for possible additional articles on AHT. All relevant articles were sorted by country and examined for article type and content. Thirty-four unique articles were located for review from 8 of 21 countries. Most of the articles identified were case reports, case series, or educational, and there were no studies regarding overall incidence or prevalence of AHT. Some scientific information contained in the articles varied considerably from that in the English language literature in the areas of etiology and preventive strategies. This survey highlights that the Spanish language literature regarding AHT is sparse and variable. This must be considered when working collaboratively in a global setting. Additionally, identification of this gap presents an opportunity for education and information exchange among global medical communities.

    2013-01-01

    Relevance theory, an inferential approach to pragmatics, claims that the hearer is expected to pick out the input of op-timal relevance from a mass of alternative inputs produced by the speaker in order to interpret the speaker ’s intentions. The de-gree of the relevance of an input can be assessed in terms of cognitive effects and the processing effort. The input of optimal rele-vance is the one yielding the greatest positive cognitive effect and requiring the least processing effort. This paper attempts to as-sess the degrees of the relevance of a mass of alternative inputs produced by an imaginary speaker from the perspective of her cor-responding hearer in terms of cognitive effects and the processing effort with a view to justifying the feasibility of the principle of relevance in pragmatic inferences.

    The concept of relevance is used ubiquitously in everyday life. However, a general quantitative definition of relevance has been lacking, especially as pertains to quantifying the relevance of sensory observations to one's goals. We propose a theoretical definition for the information value of data observations with respect to a goal, which we call "goal relevance." We consider the probability distribution of an agent's subjective beliefs over how a goal can be achieved. When new data are observed, its goal relevance is measured as the Kullback-Leibler divergence between belief distributions before and after the observation. Theoretical predictions about the relevance of different obstacles in simulated environments agreed with the majority response of 38 human participants in 83.5% of trials, beating multiple machine-learning models. Our new definition of goal relevance is general, quantitative, explicit, and allows one to put a number onto the previously elusive notion of relevance of observations to a goal.

    Little is known on the role of the senses smell and taste in end-of-life care. The presented systematic literature analysis investigates the significance of smell and taste in palliative care. The online databases PubMed, CINAHL, MEDLINE, Deutsche Nationalbibliothek and British National Library were searched for English and German literature published between 1970 and April 2013 containing any kind of original data on the impact of smell and taste in patients in a palliative care situation. All retrieved publications were screened for relevance and full text was obtained for all articles identified as relevant. We integrated 13 papers for further analysis (explorative surveys 5, clinical trials 3, case studies 2, qualitative study 1, brief report 1, clinical report 1). Prevalence of smell and taste alterations in palliative care ranges between 60 and 86%. Existing literature reflects the significance of smells and tastes in palliative care setting in two main streams--smell and taste alterations as symptoms and malodorous wounds. Prevalence of smell and taste alterations in palliative care is high. However, in palliative care literature concepts for the assessment and fostering of subjective significance of smell and taste and the individual impact of significant smells and tastes are predominantly neglected. Available instruments should be characterized, validated and adapted for the use for palliative care patients.

    2006-01-01

    Qualitative researchers address many issues relevant to patient health care. Their studies appear in an array of journals, making literature searching difficult. Large databases such as EMBASE provide a means of retrieving qualitative research, but these studies represent only a minuscule fraction of published articles, making electronic retrieval problematic. Little work has been done on developing search strategies for the detection of qualitative studies. The objective of this study was to develop optimal search strategies to retrieve qualitative studies in EMBASE for the 2000 publishing year. The authors conducted an analytic survey, comparing hand searches of journals with retrievals from EMBASE for candidate search terms and combinations. Search strategies reached peak sensitivities at 94.2% and peak specificities of 99.7%. Combining search terms to optimize the combination of sensitivity and specificity resulted in values over 89% for both. The authors identified search strategies with high performance for retrieving qualitative studies in EMBASE.

  11. Review of relevant studies of isolated systems[Integration of wind energy

    Energy Technology Data Exchange (ETDEWEB)

    Hansen, L.H.; Lundsager, P.

    2000-12-01

    The report presents the results of a review of studies relating to integration of wind energy in isolated power supply systems, based on a systematic literature survey. The purpose of the study is to develop a methodology consisting of a set of guidelines for wind energy projects in isolated energy systems and a set of tools and models that are operational on an engineering level. The review is based on a literature search in the ETDE Energy Database with a main search covering the period 7/88 to 6/97 and supplemented by partial update periods. A few newer references have been included in the review, most notably the IEC/PAS 62111 specification. The amount of wind energy literature related to the subject is excessively large, and a complete review in which every relevant abstract is identified and examined is not feasible within the framework of this (or probably any other) study. The review results have been organised according to the following keywords: methods & guides, economics, concept of application, system solutions, case studies, financial programmes, dedicated software tools. None of the found references presents methods or tools that contradict the philosophy of Risoe's methodology as it is described in the report. It is therefore concluded that Risoe's methodology makes a good platform for further development. (au)

    2017-07-01

    In the medical literature, there is little known about vaginal wind, though from clinical expertise, it turns out to be a consistent and underreported problem. The aim of this review was to collect the available literature about the different aspects of vaginal wind. A systematic literature search was conducted using three databases until December 2015. The search strategy was built using relevant synonyms of vaginal wind. Study characteristics were extracted. Risk of bias, the quality of the relevant studies and the level of evidence was judged. Eleven studies met the inclusion criteria. Vaginal wind occurs on random movements and during or after coitus. The prevalence ranges from one to 69%. The pathophysiology is unclear and the incidence unknown. Known risk factors are vaginal delivery and urinary incontinence. Provoking factors are coitus, digital stimulation, cunnilingus and exercising. Female sexual function is decreased. The sexual function of male partners with vaginal wind is not influenced. Overall vaginal wind leads to a decrease in the quality of live and can have cause social isolation. The treatment is related to the cause and mainly not successful. Tampons can be used for treatment as well as prevention. Vaginal wind is an underestimated health issue with a severe impact on sexual functioning. Adequate research is needed regarding the influence of sexual activity, weight, age, parity, the underlying pathophysiological mechanisms, prevention and treatment. Copyright © 2017 Elsevier B.V.

    Directory of Open Access Journals (Sweden)

    Kriengsak Limkittikul

    Full Text Available A literature survey and analysis was conducted to describe the epidemiology of dengue disease in Thailand reported between 2000 and 2011. The literature search identified 610 relevant sources, 40 of which fulfilled the inclusion criteria defined in the review protocol. Peaks in the number of cases occurred during the review period in 2001, 2002, 2008 and 2010. A shift in age group predominance towards older ages continued through the review period. Disease incidence and deaths remained highest in children aged ≤ 15 years and case fatality rates were highest in young children. Heterogeneous geographical patterns were observed with higher incidence rates reported in the Southern region and serotype distribution varied in time and place. Gaps identified in epidemiological knowledge regarding dengue disease in Thailand provide several avenues for future research, in particular studies of seroprevalence.PROSPERO CRD42012002170.

    Full Text Available A literature survey and analysis was conducted to describe the epidemiology of dengue disease in Malaysia between 2000 and 2012. Published literature was searched for epidemiological studies of dengue disease, using specific search strategies for each electronic database; 237 relevant data sources were identified, 28 of which fulfilled the inclusion criteria. The epidemiology of dengue disease in Malaysia was characterized by a non-linear increase in the number of reported cases from 7,103 in 2000 to 46,171 in 2010, and a shift in the age range predominance from children toward adults. The overall increase in dengue disease was accompanied by a rise in the number, but not the proportion, of severe cases. The dominant circulating dengue virus serotypes changed continually over the decade and differed between states. Several gaps in epidemiological knowledge were identified; in particular, studies of regional differences, age-stratified seroprevalence, and hospital admissions.PROSPERO #CRD42012002293.

  13. Relevance theory: pragmatics and cognition.

    Science.gov (United States)

    Wearing, Catherine J

    2015-01-01

    Relevance Theory is a cognitively oriented theory of pragmatics, i.e., a theory of language use. It builds on the seminal work of H.P. Grice(1) to develop a pragmatic theory which is at once philosophically sensitive and empirically plausible (in both psychological and evolutionary terms). This entry reviews the central commitments and chief contributions of Relevance Theory, including its Gricean commitment to the centrality of intention-reading and inference in communication; the cognitively grounded notion of relevance which provides the mechanism for explaining pragmatic interpretation as an intention-driven, inferential process; and several key applications of the theory (lexical pragmatics, metaphor and irony, procedural meaning). Relevance Theory is an important contribution to our understanding of the pragmatics of communication.

  14. Relevance theory and pragmatic impairment.

    Science.gov (United States)

    Leinonen, E; Kerbel, D

    1999-01-01

    This paper summarizes aspects of relevance theory that are useful for exploring impairment of pragmatic comprehension in children. It explores data from three children with pragmatic language difficulties within this framework. Relevance theory is seen to provide a means of explaining why, in a given context, a particular utterance is problematic. It thus enables one to move on from mere description of problematic behaviours towards their explanation. The theory provides a clearer delineation between the explicit and the implicit, and hence between semantics and pragmatics. This enables one to place certain difficulties more firmly within semantics and others within pragmatics. Relevance, and its maximization in communication, are squarely placed within human cognition, which suggests a close connection between pragmatic and cognitive (dis)functioning. Relevance theory thus emerges as a powerful tool in the exploration and understanding of pragmatic language difficulties in children and offers therapeutically valuable insight into the nature of interactions involving individuals with such impairments.

    Perreira, Tyrone A; Innis, Jennifer; Berta, Whitney

    2016-12-01

    The aim of this scoping literature review was to examine and summarize the factors, context, and processes that influence work motivation of health care workers. A scoping literature review was done to answer the question: What is known from the existing empirical literature about factors, context, and processes that influence work motivation of health care workers? This scoping review used the Arksey and O'Malley framework to describe and summarize findings. Inclusion and exclusion criteria were developed to screen studies. Relevant studies published between January 2005 and May 2016 were identified using five electronic databases. Study abstracts were screened for eligibility by two reviewers. Following this screening process, full-text articles were reviewed to determine the eligibility of the studies. Eligible studies were then evaluated by coding findings with descriptive labels to distinguish elements that appeared pertinent to this review. Coding was used to form groups, and these groups led to the development of themes. Twenty-five studies met the eligibility criteria for this literature review. The themes identified were work performance, organizational justice, pay, status, personal characteristics, work relationships (including bullying), autonomy, organizational identification, training, and meaningfulness of work. Most of the research involved the use of surveys. There is a need for more qualitative research and for the use of case studies to examine work motivation in health care organizations. All of the studies were cross-sectional. Longitudinal research would provide insight into how work motivation changes, and how it can be influenced and shaped. Several implications for practice were identified. There is a need to ensure that health care workers have access to training opportunities, and that autonomy is optimized. To improve work motivation, there is a need to address bullying and hostile behaviours in the workplace. Addressing the factors that

Relevant scientific literature and electronic databases were searched, including Pubmed and GoogleScholar, to identify studies, viewpoints and recommendations using keywords related to media and mental illnesses. This review discusses both the positive and the negative portrayals of mental illnesses through the media. The portrayal of mental health professionals and psychiatric treatment is also discussed. The theories explaining the relationship of how media influences the attitudes and behavior are discussed. Media has also been suggested to be a risk factor for the genesis or exacerbation of mental illnesses like eating disorders and substance use disorders. The potential use of media to understand the psychopathology and plight of those with psychiatric disorders is referred to. The manner in which media can be used as a tool for change to reduce the stigma surrounding mental illnesses is explored.

  10. Ways of Presenting Love in Ancient Sanskrit Literature

    Directory of Open Access Journals (Sweden)

    Fabrizia Baldissera

    2017-05-01

    Full Text Available This study traces the appearance and relevance of love motifs in Sanskrit texts. It deals with preclassical, classical and medieval literature, with excerpts from the Vedic scriptures, the epics, the normative texts and the courtly formalized Kāvya. Attention is paid to the change in the status of women, whose position becomes gradually more subordinate over time. Several conventional topoi of Sanskrit erotic literature are examined, such as love enjoyed in the union of the lovers, or suffered in their separation; divine love; the traditional belief that women are more passionate than men; the different religious/philosophical schools' outlook towards love; love in the dramatic theory of aesthetic experience; the importance of marriage, and marital love as opposed or complementary to illicit love. Finally there is a brief survey of a few scientific disciplines that have something to say about the experience of love, like Āyurveda, astronomy/astrology, and the treatises on Dharma and those on the science of government.

  11. Development, Reliability and Validity of the Thai Healthy Aging Survey

    Ladda THIAMWONG

    2009-06-01

    Full Text Available We describe the development of a healthy aging survey for older Thai adults. Domains of physical, psychological, social and spiritual health were identified as relevant based on focus groups of older Thai adults and a synthesis of Western and Thai literature on aging. A 4-phase approach was employed. First, for each domain, we selected measures that had been used in Thailand and/or in other countries, and adapted them for older Thai adults. Second, 2 forward translations from English to Thai and 1 back translation were conducted. Third, the survey was pretested by using a general debriefing pretest and cognitive interviewing. Last, the final scales were selected based on factor analysis and psychometric properties assessed in a sample of 350 older Thai community-dwelling adults. Factor analysis explained 61.8 - 74.5 % of the variance within each domain. The final survey consisted of 72 items with 16 scales. Most scales achieved good reliability; 13 scales had a Cronbach’s alpha greater than 0.70 (range 0.48 and 0.93. A 2-week test-retest reliability showed acceptable Pearson correlations. The first-generation survey demonstrates good psychometric properties and provides the basis for measuring healthy aging in the older Thai adult population. The survey may also be applicable to other cultures.

    2014-05-01

    Good literary fiction has the potential to move us, extend our sense of life, transform our prospective views and help us in the face of adversity. A neurological disorder is likely to be the most challenging experience a human being may have to confront in a lifetime. As such, literary recreations of illnesses have a doubly powerful effect. Study the synergies between neurology and fictional literature with particular reference to narrative based medicine (NBM). Doctors establish boundaries between the normal and the abnormal. Taking a clinical history is an act of interpretation in which the doctor integrates the science of objective signs and measurable quantities with the art of subjective clinical judgment. The more discrepancy there is between the patient's experience with the illness and the doctor's interpretation of that disease, the less likely the doctor-patient interaction is to succeed. NBM contributes to a better discernment of the meanings, thus considering disease as a biographical event rather than just a natural fact. Drawing from their own experience with disease, writers of fiction provide universal insights through their narratives, whilst neuroscientists, like Cajal, have occasionally devoted their scientific knowledge to literary narratives. Furthermore, neurologists from Alzheimer to Oliver Sacks remind us of the essential value of NBM in the clinic. Integrating NBM (the narrative of patients) and the classic holistic approach to patients with our current paradigm of evidence based medicine represents a challenge as relevant to neurologists as keeping up with technological and scientific advances.
