    For every mobilization of a new enterprise it is necessary to quickly obtain the greatest amount of relative information in regards to location and availability of infra-structure, logistics, and work site amenities. Among this information are reports elaborated for management of the enterprise, (organizational chart, work schedule, objectives, contacts, etc.) as well as geographic anomalies, social-economic and culture of the area to be developed such as territorial extension, land aspects, local population, roads and amenities (fuel stations ,restaurants and hotels), infra-structure of the cities (health, education, entertainment, housing, transport, etc.) and logistically the distance between cities the estimated travel time, ROW access maps and notable points, among other relevant information. With the idea of making this information available for everyone involved in the enterprise, it was elaborated for GASCAC Spread 2A a rapid guide containing all the information mentioned above and made it available for all the vehicles used to transport employees and visitors to the spread. With this, everyone quickly received the majority of information necessary in one place, in a practical, quick, and precise manner, since the information is always used and controlled by the same person. This study includes the model used in the gas pipeline GASCAC Spread 2A project and the methodology used to draft and update the information. Besides the above, a file in the GIS format was prepared containing all necessary planning, execution and tracking information for enterprise activities, from social communication to the execution of the works previously mentioned. Part of the GIS file information was uploaded to Google Earth so as to disclose the information to a greater group of people, bearing in mind that this program is free of charge and easy to use.

    2014-04-01

    Students who are deaf or hard of hearing (SDHH) are a low-incidence group of students; however, SDHH also have a high incidence of additional disabilities (SDHH+). Many SDHH and SDHH+ require accommodations for equal access to classroom instruction and assessment, particularly in mainstreamed educational settings where spoken English is the primary language. Accommodations for SDHH, overall, have increased under federal legislation including the Individuals with Disabilities Education Improvement Act and the No Child Left Behind Act. Unfortunately, specific practice recommendations for SDHH+ and their unique needs are often lacking in the research literature. This article presents findings regarding accommodations use by SDHH and SDHH+ from the National Longitudinal Transition Study 2. Initial logistic regression analysis found no differences in accommodations use of SDHH and SDHH+. However, logistic regression analysis that compared specific additional disability groups with the larger overall SDHH group did find differences in accommodations use for two SDHH+ groups: students who had a learning disability and students with attention deficit hyperactivity disorder. This article includes a discussion of the implications of these findings for both research and practice.

    Policy-making concerned with animals often includes human interests, such as economy, trade, environmental protection, disease control, species conservation etc. When it comes to the interests of the animals, such policy-making often makes use of the results of animal welfare science to provide...... assessments of ethically relevant concerns for animals. This has provided a scientific rigour that has helped to overcome controversies and allowed debates to move forward according to generally agreed methodologies. However, this focus can lead to policies leaving out other important issues relevant...... to animals. This can be considered as a problem of what is included in welfare science, or of what is included in policy. This suggests two possible solutions: expanding animal welfare science to address all ethical concerns about animals’ interests or widening the perspective considered in policy...

    2012-04-01

    There is evidence that the climate changes and that now, the change is influenced and accelerated by the CO2 augmentation in atmosphere due to combustion by humans. Such "Climate change" is on the policy agenda at the global level, with the aim of understanding and reducing its causes and to mitigate its consequences. In most countries and international organisms UNO (e.g. Rio de Janeiro 1992), OECD, EC, etc … the efforts and debates have been directed to know the possible causes, to predict the future evolution of some variable conditioners, and trying to make studies to fight against the effects or to delay the negative evolution of such. The Protocol of Kyoto 1997 set international efforts about CO2 emissions, but it was partial and not followed e.g. by USA and China …, and in Durban 2011 the ineffectiveness of humanity on such global real challenges was set as evident. Among all that, the elaboration of a global model was not boarded that can help to choose the best alternative between the feasible ones, to elaborate the strategies and to evaluate the costs, and the authors propose to enter in that frame for study. As in all natural, technological and social changes, the best-prepared countries will have the best bear and the more rapid recover. In all the geographic areas the alternative will not be the same one, but the model must help us to make the appropriated decision. It is essential to know those areas that are more sensitive to the negative effects of climate change, the parameters to take into account for its evaluation, and comprehensive plans to deal with it. The objective of this paper is to elaborate a mathematical model support of decisions, which will allow to develop and to evaluate alternatives of adaptation to the climatic change of different communities in Europe and Latin-America, mainly in especially vulnerable areas to the climatic change, considering in them all the intervening factors. The models will consider criteria of physical

  15. Gadow's relational narrative: an elaboration.

    Science.gov (United States)

    Hess, Joanne D

    2003-07-01

    Nurse philosopher Sally Gadow (1999) has proposed the relational narrative between patient and nurse as a 'postmodern turn' for nursing ethics. She has conceptualized this moral approach as the construction by patient and nurse of a coauthored narrative describing the good they are seeking, as well as the means to achieve this good. The purpose of this article is to provide an elaboration of Gadow's seminal conceptualization of relational narrative based on her writings and those of other philosophers. The article will further develop relational narrative's foundations in relationship and narrative and will explore engagement as a dimension essential to its creation and growth. The elaboration first builds on the notion of relationship as foundational to this postmodern moral perspective. Narrative then is advanced as being at the heart of the patient-nurse relationship and their relational narrative, based on an exploration of narrative's role in the moral realm as an epistemology for patient and nurse. Finally, the dialogic and embodied engagement expressed by a relational narrative is developed as a critical element of the ethic.

    The Noril'sk I, Talnakh, and Kharaelakh intrusions of the Noril'sk district host one of the outstanding metal concentrations in the world; contained Cu-Ni resources are comparable to the deposits at Sudbury, Ontario and the platinum group element (PGE) resource is second only to that of the Bushveld Complex. Our opportunity to cooperatively sample and study this district in Siberian Russia arose in 1990 through a memorandum of understanding between the U.S. Geological Survey and the former Ministry of Geology of the U.S.S.R. The world-class significance of these deposits and the possibility that understanding their geologic context, including construction of a credible 'ore-deposit model,' will lead to discovery of similar deposits elsewhere, inspired extensive studies of the ores, the mafic-intrusions which host them, and associated flood basalts.

    1996-12-01

    Because young children provide incomplete accounts of the past and tend to acquiesce to leading questions, procedures are needed to help them describe past events fully, without contaminating memory. This study tests the efficacy of "narrative elaboration," an innovative procedure designed to expand children's spontaneous reports of past events, reducing the need for leading questions. One hundred thirty-two children from 2 age groups (7-8 years and 10-11 years) were assigned randomly to 1 of 3 preparation conditions: (a) narrative elaboration intervention, (b) instruction-based intervention, and (c) control group. After participating in a staged activity and subsequent preparation sessions, children were interviewed about the activity. Children in the narrative elaboration condition demonstrated a 53% improvement in spontaneous recall over the control group, without compromising accuracy. Younger children using the narrative elaboration procedure performed at the level of older children in the control group. Discussion centers on implications for interviewing child witnesses and preparing them for courtroom examination.

  5. Matter transfer during virgin olive oil elaboration

    Directory of Open Access Journals (Sweden)

    Gómez Herrera, Carlos

    2007-06-01

    Full Text Available In the course of the process of elaboration of virgin olive oil (whose main stages are crushing, malaxation and centrifugation the transfer of several minor components to the triacylglycerol constituent of the oily globules originally present in the cells of the fruit mesocarp is produced. Such minor components are chemical species present in the olive fruits, as well as those resulting from chemical or enzymatic processes which take place in the olive paste upon crushing. In this paper several types of transferable minor components, as well as those parameters affecting the rates of transfer are studied.Geometric and physical variations of interfacial regions between the oil and other systems in contact with it are discussed. These systems are olive vegetation water, olive pulp components, and fragments of the woody endocarp, as well as the atmospheric air and the tools and equipment of the oil mill.This article concludes with some considerations about the improvements of virgin olive oils achieved by controlling the transfer of minor components.Durante la elaboración del aceite de oliva virgen (cuyas principales etapas son molturación, batido y centrifugación se producen transferencias de diversos componentes menores a los triacilgliceroles originalmente presentes en los glóbulos oleosos de las células del mesocarpio de los frutos. Estos componentes menores son especies químicas presentes en las aceitunas, así como especies resultantes de procesos químicos o enzimáticos que se producen en la pasta a partir de la molturación. En este artículo se estudian diversos tipos de componentes menores transferibles, así como aquellos parámetros que afectan sus velocidades de transferencia.Se discuten las variaciones geométricas y físicas de las regiones interfaciales situadas entre el aceite y los otros sistemas en contacto con el mismo. Estos sistemas son el agua de vegetación, los componentes de la pulpa y los fragmentos de endocarpio

    2015-11-01

    Clinical guidelines are documents to help professionals and patients select the best diagnostic or therapeutic option. Elaborating guidelines requires an efficient literature search and a critical evaluation of the articles found to select the most appropriate ones. After that, the recommendations are formulated and then must be externally evaluated before they can be disseminated. Even when the guidelines are very thorough and rigorous, it is important to know whether they fulfill all the methodological requisites before applying them. With this aim, various scales have been developed to critically appraise guidelines. Of these, the AGREE II instrument is currently the most widely used. This article explains the main steps in elaborating clinical guidelines and the main aspects that should be analyzed to know whether the guidelines are well written. Copyright © 2015 SERAM.

  8. Development of measures to assess the safety of existing NPPs and the effectiveness of regulations and regulatory actions (including 'prescriptive' and 'performance based' approaches). Peer discussions on regulatory practices

    International Nuclear Information System (INIS)

    1996-09-01

    This report arises from the fourth series of peer discussions on regulatory practices entitled D evelopment of measures to assess the safety of existing nuclear power plants and the effectiveness of regulations and regulatory actions (including 'prescriptive' and 'performance based' approaches) . Senior regulators from 23 Member States participated in four peer group discussions during 1995-1996. This report presents the outcome of these meetings and recommendations of good practices identified by these senior regulators. The purpose of this report is to disseminate the views which the senior regulators presented at the meetings relating to measures used for assessing the safety of existing nuclear power plants and evaluating the effectiveness of regulators and regulatory actions. The intention in doing this is to assist Member States in the enhancement of their regulatory practices by identifying commonly accepted good practices. This report is structured so that it covers the subject matter under the following main headings: 'Prescriptive and Performance Based' Approaches to Regulation; Common Features of Regulatory Approaches; Effectiveness of the Regulator and Regulatory Actions; Recommendations of Good Practice. It is important to note that recommendations of good practice are included if they have been identified by at least one of the groups. It does not follow that all of the groups or individual Member States would necessarily endorse all of the recommendations. However, it is considered that if a single group of senior regulators judge that a particular practice is worthy of recommendation then it should be included for serious consideration. In some cases the same recommendations arise from all of the Groups

    2013-12-01

    Llewellyn's proposal that rapid eye movement (REM) dreaming reflects elaborative encoding mediated by the hippocampus ("seahorse") offers an interesting perspective for understanding hallucinations accompanying sleep paralysis (SP; "night-mare"). SP arises from anomalous intrusion of REM processes into waking consciousness, including threat-detection systems mediated by the amygdala ("almond"). Unique aspects of SP hallucinations offer additional prospects for investigation of Llewellyn's theory of elaborative encoding.

    As titanium nitride is a very interesting and promising material for the protection against wear and corrosion of metals and alloys with a low fusion point, and notably steels, this research thesis reports the study of the elaboration of a TiN coating by activated reactive evaporation. In a first part, the author describes deposition processes based on evaporation and their characteristics. He explains the choice of the studied process. He discusses published data and results related to the titanium-nitrogen system. He describes the apparatus and reports the operation mode adjustment, and reports the study of the influence of operating conditions (substrate temperature, nitrogen pressure, evaporation rate, possible use of a discharge) on growth kinetics and on coating properties. A reaction mechanism is then proposed to describe and explain the obtained results [fr

  15. The Elaborated Environmental Stress Hypothesis as a Framework for Understanding the Association between Motor Skills and Internalizing Problems: A mini-review

    2016-02-01

    Full Text Available Poor motor skills have been shown to be associated with a range of psychosocial issues, including internalizing problems (anxiety and depression. While well-documented empirically, our understanding of why this relationship occurs remains theoretically underdeveloped. The Elaborated Environmental Stress Hypothesis by Cairney, Rigoli, and Piek (2013 provides a promising framework that seeks to explain the association between motor skills and internalizing problems, specifically in children with Developmental Coordination Disorder (DCD. The framework posits that poor motor skills predispose the development of internalizing problems via interactions with intermediary environmental stressors. At the time the model was proposed, limited direct evidence was available to support or refute the framework. Several studies and developments related to the framework have since been published. This mini-review seeks to provide an up-to-date overview of recent developments related to the Elaborated Environmental Stress Hypothesis. We briefly discuss the past research that led to its development, before moving to studies that have investigated the framework since it was proposed. While originally developed within the context of DCD in childhood, recent developments have found support for the model in community samples. Through the reviewed literature, this article provides support for the Elaborated Environmental Stress Hypothesis as a promising theoretical framework that explains the psychosocial correlates across the broader spectrum of motor ability. This evidence promotes the external validity of the framework for use across the broader spectrum of motor ability. However, given its recent conceptualisation, ongoing evaluation of the Elaborated Environmental Stress Hypothesis is recommended.

While originally developed within the context of DCD in childhood, recent developments have found support for the model in community samples. Through the reviewed literature, this article provides support for the Elaborated Environmental Stress Hypothesis as a promising theoretical framework that explains the psychosocial correlates across the broader spectrum of motor ability. However, given its recent conceptualization, ongoing evaluation of the Elaborated Environmental Stress Hypothesis is recommended.

    Monteiro, Iara A.; Pitta, Maria Adelia R.; Pereira, Enneite S.; Wieland, Patricia

    2009-01-01

    This paper presents and discusses the process of public consultation followed by the regulatory body, Nuclear Energy National Commission (CNEN), during the elaboration of nuclear regulations. In this paper, the due legislation on federal administration, law n. 9784/99, is referred to and the procedures established by CNEN for the elaboration of a nuclear regulation are described. The public consultation has the objective of improving the democratization of nuclear regulations elaboration process, allowing the participation of interested parties such as professional associations directly involved, organizations interested in its application and the general public. During the process of elaboration of a nuclear regulation, the basic text is, first of all, discussed and improved by a task group. This group is composed by CNEN's officials and representatives of organizations, enterprises and public agencies involved in the related area. Once the first version of the proposed regulation is ready, it is formally open to consultation and posted at CNEN website for a period of time. The suggestions, therein presented on-line, are analyzed by the task group and the conclusions are also posted at the site; those considered pertinent are incorporated to proposed regulation. As an example, the public consultation results obtained in 2008 with the revision of the CNEN-NN-6.02: Licensing of Radioactive Facilities regulation, are presented. Such results cover two aspects: the analysis of the participants profile and the analysis of the contributions. Public participation in the elaboration of nuclear regulations is a new way for CNEN to know the licensees and public demands, doubts and needs. This tool has demonstrated usefulness and therefore must be maintained by the regulatory body. (author)

    Withers, Giselle F; Wertheim, Eleanor H

    2004-01-01

    This study applied principles from the Elaboration Likelihood Model of Persuasion to the prevention of disordered eating. Early adolescent girls watched either a preventive videotape only (n=114) or video plus post-video activity (verbal discussion, written exercises, or control discussion) (n=187); or had no intervention (n=104). Significantly more body image and knowledge improvements occurred at post video and follow-up in the intervention groups compared to no intervention. There were no outcome differences among intervention groups, or between girls with high or low elaboration likelihood. Further research is needed in integrating the videotape into a broader prevention package.

    Much medical research is observational. The reporting of observational studies is often of insufficient quality. Poor reporting hampers the assessment of the strengths and weaknesses of a study and the generalisability of its results. Taking into account empirical evidence and theoretical considerations, a group of methodologists, researchers, and editors developed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations to improve the quality of reporting of observational studies. The STROBE Statement consists of a checklist of 22 items, which relate to the title, abstract, introduction, methods, results and discussion sections of articles. Eighteen items are common to cohort studies, case-control studies and cross-sectional studies and four are specific to each of the three study designs. The STROBE Statement provides guidance to authors about how to improve the reporting of observational studies and facilitates critical appraisal and interpretation of studies by reviewers, journal editors and readers. This explanatory and elaboration document is intended to enhance the use, understanding, and dissemination of the STROBE Statement. The meaning and rationale for each checklist item are presented. For each item, one or several published examples and, where possible, references to relevant empirical studies and methodological literature are provided. Examples of useful flow diagrams are also included. The STROBE Statement, this document, and the associated Web site (http://www.strobe-statement.org/) should be helpful resources to improve reporting of observational research.

    ENEA (Italian Agency for New Technologies, Energy and the Environment) was designated by the Ministry of Environment to elaborate the remediation plan for contaminated sites of Puglia region. The plan was developped by ENEA, following criteria and guidelines fixed by the Environment Department in a decree of may 16th 1989. The activities of the plan were conducted through the following four stages: census and mapping of potentially contaminated sites; settlement of the first list of contaminated sites to submit to remediation; program elaboration for short term interventions on site remediation and drafting general projects; program elaboration for middle term interventions on site remediation. The information collected about all sites during the investigations have been organized on a database, in which an algorithm permits the risk indexes for each site be calculated automatically

  9. Institutions, Anomie, and Violent Crime: Clarifying and Elaborating Institutional-Anomie Theory

    Directory of Open Access Journals (Sweden)

    Richard Rosenfeld

    2008-11-01

    Full Text Available A limited but accumulating body of research and theoretical commentary offers support for core claims of the “institutional-anomie theory” of crime (IAT and points to areas needing further development. In this paper, which focuses on violent crime, we clarify the concept of social institutions, elaborate the cultural component of IAT, derive implications for individual behavior, summarize empirical applications, and propose directions for future research. Drawing on Talcott Parsons, we distinguish the “subjective” and “objective” dimensions of institutional dynamics and discuss their interrelationship. We elaborate on the theory’s cultural component with reference to Durkheim’s distinction between “moral” and “egoistic” individualism and propose that a version of the egoistic type characterizes societies in which the economy dominates the institutional structure, anomie is rampant, and levels of violent crime are high. We also offer a heuristic model of IAT that integrates macro- and individual levels of analysis. Finally, we discuss briefly issues for the further theoretical elaboration of this macro-social perspective on violent crime. Specifically, we call attention to the important tasks of explaining the emergence of economic dominance in the institutional balance of power and of formulating an institutional account for distinctive punishment practices, such as the advent of mass incarceration in the United States.

    In order to choose areas to implement pipe yards, terminals, campsite, pipeline path and other areas of assistance for the construction and assembly of the pipeline, it is necessary previous location studies to elaborate the basic drawing. However it is not always possible to contract a company registered in aerial survey to elaborate this type of drawing, either for the cost or time, and where the lack of a basic drawing can lead to an erroneous choice or one which reflects an exaggerated estimate or not adequate logistics. In order to minimize costs and optimizing time, without compromising quality, this study proposes the use of software 'virtual globe' type for mapping and geographic location available on the internet to assist in the gathering of geographical, altimetric, hydro graphic, road, environmental, socioeconomic and aerial images, information necessary to elaborate the basic drawing. This article includes a case study of the oil pipeline Cacimbas-Barra do Riacho project and a proposed procedure to be used in the elaboration of basic drawings using data generated using the referred to software. In 2007 the Pipeline Construction and Assembly sector, CMDPI unit of PETROBRAS Engenharia/IETEG/IEDT was designated to select an area of 2 hectares where the pipe storage yard for pipes to be used in the Oil Pipeline Cacimbas- Barra do Riacho in Espirito Santo state would be constructed. The area was chosen following some pre-requisites and using as main resources in the gathering of information necessary to select the area, 'virtual globe' type software and a CAD type software with the capacity to import images and altimetric identification as well as exporting drawing data to the mentioned. The activity, much simpler than hiring an aerial survey, was elaborated surpassing expectations of time-costs besides complying with the necessary technical demands. (author)

    Most important task of archaeomagnetic studies is the construction of the geomagnetic field secular variations in the past for a given territory. The obtained reference curves would be precise only when a large number of well-dated archaeological sites from different time periods are included as input data. Sofia Palaeomagnetic laboratory is the first one in the Balkans to accumulate a large number of data spanning the time interval of 3000 BP to 8000 BP. Many archaeological sites in Bulgaria are multilevel settlements with clear stratigraphy. Commonly the prehistoric sites are dated according to the relative chronology, the type of archaeological artifacts found and 14C dates, the latter being not always available. The biggest difficulty is that usually the radiocarbon dates are not well constrained, often contradictory to the vertical stratigraphy. The transformation of conventional 14C dates to absolute dates BC depends a lot on which part of dendrochronological calibration curve are they related. Besides, multiple dating intervals are often obtained and the calibrated intervals are usually very large (from 100 to 300 and more years). However, when archaeological discoveries of multilevel prehistoric sites are combined with archaeomagnetic investigations the corresponding archaeomagnetic profiles can be obtained. Currently we have archaeomagnetic data for fifteen prehistoric multilevel sites - two of them are Neolithic, nine - Eneolithic and four are from the Bronze Age. The next step is to juxtapose these stratigraphic profiles with the absolute scale of time having in mind that not all sites and layers have 14C dates. Thanks to abundance of 14C dates for most of Bulgarian prehistoric sites, multilayer sites connected with the absolute chronology exist and can be used as reference profiles. The time frames of each horizon for such reference site are based on series of 14C dates (not single measurements), the analysis of the thickness of layers, type of material

    In order to propose a new MOX fuel, owning higher combustion rate, studies are realized at the CEA in collaboration with Cogema, EDF and Framatome. New microstructures of MOX are looked for around two approaches: the grains size and the plutonium distribution. These approaches are presented and discussed in this paper. The first one develops big grains microstructures obtained, either with anionic (sulfur), or cationic (Cr{sub 2}O{sub 3}) additives. The second one concerns the CER-CER type composite microstructures. (A.L.B.)

    Full Text Available Assistive Technologies consists of resources, methods, and strategies favoring autonomy and inclusion of elderly and people with disabilities, being scarce in the literature instruments assessing them. A methodology study conducted with a panel of specialists and people with visual impairment, aimed to elaborate and validate a questionnaire to assess educational assistive technology. To consider an item as valid, we used 80% as agreement percentage, and validity and reliability of the questionnaire were calculated. Assistive Technology was characterized in six attributes: objectives, access, clarity, structure and presentation, relevance and efficacy, interactivity, and 19 items were elaborated to compose the questionnaire. From those, 11 obtained percentages higher than 80%, seven were modified and one was excluded. The instrument Cronbach’s alpha was 0,822, guaranteeing validity and reliability of the tool to assess health education Assistive Technology, and therefore, its use is indicated.

This study elaborates these theories in a Public Lecture series which to persuade the students in choosing their concentration of study. The result shows that in term of persuasion effectiveness it is not quite relevant to separate the message and its source. The quality of source is determined by the quality of the message, and vice versa. Separating the two routes of the persuasion process as described in the ELM theory would not be relevant.

    2012-07-01

    Full Text Available In this paper, we focus on the Elaboration relation and on its automatic identification in French, using the theoretical framework of Segmented Discourse Representation Theory (SDRT. One of the information sources identified by the SDRT framework to infer the Elaboration relation is based on the existence of a potential subsumption link between the eventualities at stake, depending on lexical semantics and world knowledge. We investigate this claim by combining a weak syntactic marker of the Elaboration relation, namely the gerund clause, with lexical cohesion cues. We aim at automatically identifying gerund clauses which are Elaborations by finding cohesive links between the host main clause and the gerund clause. This approach makes it possible to accurately detect few cases of intra-sentential Elaborations in our corpus, confirming the fact that lexical cohesion cues are relevant for this task.Dans cet article, nous nous focalisons sur la relation d’Élaboration en français, telle qu’elle est décrite dans le modèle théorique de la SDRT (Segmented Discourse Representation Theory, et sur son identification automatique. Selon la SDRT, une des sources d’information permettant d’inférer la relation d’Élaboration est basée sur l’existence d’un lien de subsomption entre les types des éventualités des segments à relier, indiquant que le type de la seconde éventualité est un sous-type de celui de la première dans la sémantique lexicale des éventualités ou grâce à des connaissances du monde. Nous proposons de contribuer à cette question en combinant un indice de la relation d’Élaboration, i. e. la construction syntaxique du gérondif, et des indices de cohésion lexicale. Notre objectif est d’identifier automatiquement des propositions gérondives qui sont des Élaborations en repérant des indices de cohésion lexicale entre la proposition principale et la proposition gérondive.

    For more than twenty years, the European Pharmacopoeia (Ph. Eur.) monographs for biotherapeutic proteins have been elaborated using the multisource approach (Procedure 1), which has led to robust quality standards for many of the first-generation biotherapeutics. In 2008, the Ph. Eur. opened up the way towards an alternative mechanism for the elaboration of monographs (Procedure 4-BIO pilot phase), which is applied to substances still under patent protection, based on a close collaboration with the Innovator company, to ensure a harmonised global standard and strengthen the quality of the upcoming products. This article describes the lessons learned during the P4-BIO pilot phase and addresses the current thinking on monograph elaboration in the field of biotherapeutics. Case studies are described to illustrate the standardisation challenges associated with the complexity of biotherapeutics and of analytical procedures, as well as the approaches that help ensure expectations are met when setting monograph specifications and allow for compatibility with the development of biosimilars. Emphasis is put on monograph flexibility, notably by including tests that measure process-dependent microheterogeneity (e.g. glycosylation) in the Production section of the monograph. The European Pharmacopoeia successfully concluded the pilot phase of the P4-BIO during its 156 th session on 22-23 November 2016.

  13. Fuel ethanol discussion paper

    International Nuclear Information System (INIS)

    1992-01-01

    In recognition of the potential benefits of ethanol and the merits of encouraging value-added agricultural development, a committee was formed to develop options for the role of the Ontario Ministry of Agriculture and Food in the further development of the ethanol industry in Ontario. A consultation with interested parties produced a discussion paper which begins with an outline of the role of ethanol as an alternative fuel. Ethanol issues which require industry consideration are presented, including the function of ethanol as a gasoline oxygenate or octane enhancer, environmental impacts, energy impacts, agricultural impacts, trade and fiscal implications, and regulation. The ethanol industry and distribution systems in Ontario are then described. The current industry consists of one ethanol plant and over 30 retail stations. The key issue for expanding the industry is the economics of producing ethanol. At present, production of ethanol in the short term depends on tax incentives amounting to 23.2 cents/l. In the longer term, a significant reduction in feedstock costs and a significant improvement in processing technology, or equally significant gasoline price increases, will be needed to create a sustainable ethanol industry that does not need incentives. Possible roles for the Ministry are identified, such as support for ethanol research and development, financial support for construction of ethanol plants, and active encouragement of market demand for ethanol-blended gasolines

  15. Encouraging Classroom Discussion

    2014-10-01

    Full Text Available Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

    1981-01-01

    Human peripheral blood mononuclear cells (PBMC) activated with the mitogenic lectin concanavalin A (Con A) elaborate a soluble immune suppressor supernatant (SISS) that contains at least 2 distinct suppressor factors. One of these, SISS-B, inhibits polyclonal B cell immunoglobulin production, whereas the other, SISS-T, suppresses T cell proliferation to both mitogens and antigens. The latter mediator is discussed in the companion paper. Characteristics of the human soluble suppressor of B cell immunoglobulin production (SISS-B) include: 1) inhibition by a noncytotoxic mechanism, 2) loss of activity in the presence of the monosaccharide L-rhamnose, 3) appearance within 8 to 16 hr after the addition of Con A, 4) elaboration by cells irradiated with 500 or 2000 rads, 5) production by highly purified T cells, 6) stability at pH 2.5 but instability at 56/sup o/C, and 7) m.w. of 60 to 80,000. These data indicate that after Con A activation, selected T cells not only become potent suppressor cells, but also generate a soluble saccharide-specific factor(s) that inhibits polyclonal immunoglobulin production by human B cells

  20. Elaboration over a discourse facilitates retrieval in sentence processing

    Full Text Available Language comprehension requires access to stored knowledge and the ability to combine knowledge in new, meaningful ways. Previous work has shown that processing linguistically more complex expressions (‘Texas cattle rancher’ vs. ‘rancher’ leads to slow-downs in reading during initial processing, possibly reflecting effort in combining information. Conversely, when this information must subsequently be retrieved (as in filler-gap constructions, processing is facilitated for more complex expressions, possibly because more semantic cues are available during retrieval. To follow up on this hypothesis, we tested whether information distributed across a short discourse can similarly provide effective cues for retrieval. Participants read texts introducing two referents (e.g., two senators, one of whom was described in greater detail than the other (e.g., ‘The Democrat had voted for one of the senators, and the Republican had voted for the other, a man from Ohio who was running for president’. The final sentence (e.g., ‘The senator who the {Republican / Democrat} had voted for…’ contained a relative clause picking out either the Many-Cue referent (with ‘Republican’ or the One-Cue referent (with ‘Democrat’. We predicted facilitated retrieval (faster reading times for the Many-Cue condition at the verb region (‘had voted for’, where readers could understand that ‘The senator’ is the object of the verb. As predicted, this pattern was observed at the retrieval region and continued throughout the rest of the sentence. Participants also completed the Author/Magazine Recognition Tests (ART/MRT; Stanovich & West, 1989, providing a proxy for world knowledge. Since higher ART/MRT scores may index (a greater experience accessing relevant knowledge and/or (b richer/more highly-structured representations in semantic memory, we predicted it would be positively associated with effects of elaboration on retrieval. We did not observe

  1. Ecofriendly bricks elaborated from coal waste of Moroccan Jerrada Mining

    2018-01-01

    Full Text Available Solid waste generated during mining is one of the major environmental problems associated with this industrial activity. The best solution to overcome the environmental impact of this waste is to find recycling facilities in mass-produced products that can absorb the large quantities of these available byproducts. The present study shows the feasibility of using the coal waste of Moroccan Jerrada mining in the production of ecological brick. The first step consists of consecutive stages of crushing, grinding and heating at 650°C of the coal waste with a small amount of lime in order to promote the reactive products of elaborated binders. The second step of the process consists of mixing treated coal waste with a small amount of marble dust, sand, gravel, and water, then pressed and dried at room temperature to manufacture a laboratory ecofriendly bricks. The mechanical strength and thermal conductivity are investigated.

    be used to conceptualise the elaboration and concretization of a formal curriculum, an example of radical-local teaching and learning is presented. The key point is the need to create conditions for subject-matter learning that supports personality development. This perspective provides useful principles......Education, as a societal practice, is aimed at supporting human development. Formal curricula are understood to be a means toward that end, and not an end in itself. That is, curricula are meant to express the qualities and capabilities that students are supposed to acquire as a consequence...... of educational actions. In practice, a curriculum does not provide much analytic insight for how to realise the ideals which they express, nor does it provide insight into the interactions that arise as students engage with the content of the curriculum.

    2013-10-01

    Full Text Available There is increasing demand for project management knowledge and experience as well as non-trivial ways of teaching those who are not experienced in this field. Teaching this subject must provide solid theory basis, especially in PMBoK good practices and processes, as well as the capacity of properly executing tools and techniques defined in this document. One of the processes that students in undergraduation and graduation courses find more difficult is the elaboration of the WBS. This work is aimed at assessing such difficulties, proposing mechanisms to reduce them and increasing the quality of this artifact produced by students.

    Lecours, Serge; Bouchard, Marc-André

    2011-03-01

    The present study explores the relationship between the mentalization of distinct affect categories and the severity of borderline personality disorder (BPD) symptoms. Mentalization is assessed by both the level of verbal elaboration (VE) achieved by discrete affects (explicit mentalization) and the proportion of these individual affects in verbal expression (implicit mentalization). Sixty-four outpatients completed a series of questionnaires and took part in an interview designed to produce eight relationship episodes that involved four basic emotions: sadness, joy, anger, and fear (two of each). Affect mentalization was assessed with the Grille de l'Élaboration Verbale de l'Affect (GEVA), an observer-rated measure of levels of elaboration of verbalized affect, and the measure of affect content (MAC), which identifies the content of the verbalized affect (e.g., anger). Diagnostic criteria were obtained with the BPD scale of the Structured Clinical Interview for DSM-IV (SCID-II) questionnaire. Alexithymia was assessed with the 20-item Toronto Alexithymia Scale (TAS-20). The severity of BPD symptoms was related to lower levels of VE of sadness. It was also associated with a higher frequency of hostility directed against others. The level of VE of sadness and the proportion of hostility showed incremental predictive value of borderline symptomatology over demographic information, the presence of a depressive disorder and alexithymia. These findings point to an association between the severity of BPD symptoms and a difficulty mentalizing specific affective domains largely recognized as being central to borderline pathology, namely sadness and hostility. © 2011 The British Psychological Society.

    2013-01-01

    Two main by-products or waste from the production of glass fibre are following: sewage sludge containing montmorillonite clay as sorbent material and ca 50 % of organic matter as well as waste glass from aluminium borosilicate glass fibre with relatively high softening temperature (> 600 degree centigrade). In order to elaborate different new ceramic products (porous or dense composites) the mentioned by-products and illitic clay from two different layers of Apriki deposit (Latvia) with illite content in clay fraction up to 80-90 % was used as a matrix. The raw materials were investigated by differential-thermal (DTA) and XRD analysis. Ternary compositions were prepared from mixtures of 15 - 35 wt % of sludge, 20 wt % of waste glass and 45 - 65 wt % of clay and the pressed green bodies were thermally treated in sintering temperature range from 1080 to 1120 degree centigrade in different treatment conditions. Materials produced in temperature range 1090 - 1100 degree centigrade with the most optimal properties - porosity 38 - 52 %, water absorption 39 -47 % and bulk density 1.35 - 1.67 g/cm 3 were selected for production of porous ceramics and materials showing porosity 0.35 - 1.1 %, water absorption 0.7 - 2.6 % and bulk density 2.1 - 2.3 g/cm 3 - for dense ceramic composites. Obtained results indicated that incorporation up to 25 wt % of sewage sludge is beneficial for production of both ceramic products and glass-ceramic composites according to the technological properties. Structural analysis of elaborated composite materials was performed by scanning electron microscopy(SEM). By X-ray diffraction analysis (XRD) the quartz, diopside and anorthite crystalline phases were detected. (Author)

    Wammes, Jeffrey D; Meade, Melissa E; Fernandes, Myra A

    2017-09-01

    Traditionally, students adopt the strategy of taking written notes when attending a class or learning from a textbook in educational settings. Informed by previous work showing that learning by doing improves memory performance, we examined whether drawing to-be-remembered definitions from university textbooks would improve later memory, relative to a more typical strategy of rote transcription. Participants were asked to either write out the definition, or to draw a picture representative of the definition. Results indicated that drawing, relative to verbatim writing, conferred a reliable memorial benefit that was robust, even when participants' preexisting familiarity with the terms was included as a covariate (in Experiment 1) or when the to-be-remembered terms and definitions were fictitious, thus removing the influence of familiarity (in Experiment 2). We reasoned that drawing likely facilitates retention at least in part because at encoding, participants must retain and elaborate upon information regarding the meaning of the definition, to translate it into a new form (a picture). This is not the case when participants write out the definitions verbatim. In Experiment 3 we showed that paraphrasing during encoding, which, like drawing and in contrast with verbatim writing, requires self-generated elaboration, led to memory performance that was comparable to drawing. Taken together, results suggest that drawing is a powerful tool which improves memory, and that drawing produces a similar level of retention as does paraphrasing. This suggests that elaborative encoding plays a critical role in the memorial benefit that drawing confers to memory for definitions of academic terms. Copyright © 2017 Elsevier B.V.

    2005-01-01

    Full text: International new efforts for the reconversion of HEU in research, testing and radioisotopes production reactors, have greatly incremented U-Mo fuels qualification activities. These qualifications require the resolution of undesired interaction at high fluxes between UMo particles and the aluminum matrix in the case of dispersed fuels and the development of U-Mo monolithic fuels. These efforts are being manifested in the planning and execution of additional series of irradiation tests of mini plates and full size plates. Recently, CNEA has elaborated mini plates with different proposals for the irradiation at the ATR reactor (250 MWTH, maximum thermal neutron flux 10 15 n.cm -2 .seg -1 ) at Idaho National Laboratory, USA. Uranium 7% (w/w) molybdenum (U-7Mo) particles were coated with silicon. Chemical vapour deposition (CVD) of silane and high temperature diffusion of silicon were used. Hydrided, milled and dehydrated (HMD) particles heat treated at 1000 C degrees during four hours and centrifugal atomized powder were coated and the results compared. Mini plates were elaborated with both kinds of particles. Mini plates were also elaborated with U-7Mo and silicon particles dispersed in the aluminium matrix. Monolithic mini plates were also developed by co lamination of U-7Mo with a Zircaloy-4 cladding. The different steps of this process are detailed and the method is shown to be versatile, can be easily scaled up and is performed with small modifications of usual equipment in fuel plants. The irradiation experiment is called RERTR-7A, includes a total of 32 mini plates and it is planed to finalize by mid 2006. (author) [es

    Montero, Xabier; Pauporté, Thierry; Ringuedé, Armelle; Vannier, Rose-Noelle; Cassir, Michel

    In order to adapt the anodisation technique to SOFC application, zirconium and zirconium-niobium alloys were tested in various electrolytic media and applied potentials (up to 420 V). The elaborated ZrO 2 insulating layers were characterised in situ by electrochemical impedance spectroscopy and their thicknesses were determined as ranging up to 1 μm. The effect of thermal annealing treatment of layers prepared in various experimental conditions was investigated by X-ray diffraction (XRD) and solid-state electrochemical impedance spectroscopy in a planar configuration. The effect of the growing conditions on significant parameters such as zirconia crystallite size, zirconia conductivity and activation energy were deduced up to 800 °C. The possibility of using the anodisation process for fuel cell devices is discussed. This study demonstrates that it surely requires the use of more efficient dopants, such as yttria.

  17. SOXE neofunctionalization and elaboration of the neural crest during chordate evolution

    During chordate evolution, two genome-wide duplications facilitated acquisition of vertebrate traits, including emergence of neural crest cells (NCCs), in which neofunctionalization of the duplicated genes are thought to have facilitated development of craniofacial structures and the peripheral nervous system. How these duplicated genes evolve and acquire the ability to specify NC and their derivatives are largely unknown. Vertebrate SoxE paralogues, most notably Sox9/10, are essential for NC induction, delamination and lineage specification. In contrast, the basal chordate, amphioxus, has a single SoxE gene and lacks NC-like cells. Here, we test the hypothesis that duplication and divergence of an ancestral SoxE gene may have facilitated elaboration of NC lineages. By using an in vivo expression assay to compare effects of AmphiSoxE and vertebrate Sox9 on NC development, we demonstrate that all SOXE proteins possess similar DNA binding and homodimerization properties and can induce NCCs. However, AmphiSOXE is less efficient than SOX9 in transactivation activity and in the ability to preferentially promote glial over neuronal fate, a difference that lies within the combined properties of amino terminal and transactivation domains. We propose that acquisition of AmphiSoxE expression in the neural plate border led to NCC emergence while duplication and divergence produced advantageous mutations in vertebrate homologues, promoting elaboration of NC traits.

    2012-01-01

    The High power laser development required the need of materials with nonlinear properties. Glass materials can be considered as ideal materials as they can be transparent and elaborated in very large dimension. Precipitation of non-centro symmetric crystalline particles in bulk glass leads to a material with bulk nonlinear properties. This glass-ceramic should be then easily integrated in such laser facilities. In this thesis, the results concerning the precipitation of the phase LiNbO 3 in the glassy-matrix 35 Li 2 O - 25 Nb 2 O 5 - 40 SiO 2 are detailed. The crystallization mechanism of this phase is studied through thermal analysis, optical and electronic microscopy as well as in-situ analyses. These studies reveal glass-ceramics are obtained through a precipitation of the lithium niobate crystalline phase in spherulite shape. The nonlinear optical properties are investigated on this materials and an original, isotropic Second Harmonic Generation Signal (SHG) is registered in the bulk glass-ceramic. A complete study using a multi-scale approach allows the correlation between the spherulite structure and the nonlinear optical properties. A mechanism at the origin of the SHG signal is proposed. This leads to a new approach for transparent inorganic materials development for isotropic SHG conversion. (author) [fr

    Highlights: • Successfully deposition of a glassy thin film by PLD. • A good homogeneity and stoichiometry of the coating. • Influence of the deposition temperature on the glassy thin-film structure. - Abstract: In the present work, we report the elaboration of aluminosilicate glass thin films by Pulsed Laser Deposition at various temperatures deposition. The amorphous nature of glass thin films was highlighted by Grazing Incidence X-Ray Diffraction and no nanocristallites were observed in the glassy matrix. Chemical analysis, obtained with X-ray Photoelectron Spectroscopy and Time of Flight Secondary Ion Mass Spectroscopy, showed a good transfer and homogeneous elementary distribution with of chemical species from the target to the film a. Structural studies performed by Infrared Spectroscopy showed that the substrate temperature plays an important role on the bonding configuration of the layers. A slight shift of Si-O modes to larger wavenumber was observed with the synthesis temperature, assigned to a more strained sub-oxide network. Finally, optical properties of thins film measured by Spectroscopic Ellipsometry are similar to those of the bulk aluminosilicate glass, which indicate a good deposition of aluminosilicate bulk glass.

    Full Text Available ABSTRACT Objective: to elaborate an instrument for the measurement of the interpersonal relationship in nursing care through the Item Response Theory, and the validation thereof. Method: methodological study, which followed the three poles of psychometry: theoretical, empirical and analytical. The Nursing Care Interpersonal Relationship Questionnaire was developed in light of the Imogene King’s Interpersonal Conceptual Model and the psychometric properties were studied through the Item Response Theory in a sample of 950 patients attended in Primary, Secondary and Tertiary Health Care. Results: the final instrument consisted of 31 items, with Cronbach’s alpha of 0.90 and McDonald’s Omega of 0.92. The parameters of the Item Response Theory demonstrated high discrimination in 28 items, being developed a five-level interpretive scale. At the first level, the communication process begins, gaining a wealth of interaction. Subsequent levels demonstrate qualitatively the points of effectiveness of the interpersonal relationship with the involvement of behaviors related to the concepts of transaction and interaction, followed by the concept of role. Conclusion: the instrument was created and proved to be consistent to measure interpersonal relationship in nursing care, as it presented adequate reliability and validity parameters.

    Under the situation of an urban environment, noise has been a critical issue in affecting the indoor environment. A reliable approach is required for evaluation of the community noise as one factor of anthrophonic in the urban environment. This research investigates the level of noise exposure from different community noise sources and elaborates the advantage of the noise disadvantages for soundscape innovation. Integrated building element design as a protector for noise control and speech intelligibility compliance using field experiment and MATLAB programming and modeling are also carried out. Meanwhile, for simulation analysis and building acoustic optimization, Sound Reduction-Speech Intelligibility and Reverberation Time are the main parameters for identifying tropical building model as case study object. The results show that the noise control should consider its integration with the other critical issue, thermal control, in an urban environment. The 1.1 second of reverberation time for speech activities and noise reduction more than 28.66 dBA for critical frequency (20 Hz), the speech intelligibility index could be reached more than fair assessment, 0.45. Furthermore, the environmental psychology adaptation result “Close The Opening” as the best method in high noise condition and personal adjustment as the easiest and the most adaptable way.

  4. The elaborate plumage in peacocks is not such a drag.

    One of the classic examples of an exaggerated sexually selected trait is the elaborate plumage that forms the train in male peafowl Pavo cristatus (peacock). Such ornaments are thought to reduce locomotor performance as a result of their weight and aerodynamic drag, but this cost is unknown. Here, the effect that the train has on take-off flight in peacocks was quantified as the sum of the rates of change of the potential and kinetic energies of the body (P(CoM)) in birds with trains and following the train's removal. There was no significant difference between P(CoM) in birds with and without a train. The train incurs drag during take-off; however, while this produces a twofold increase in parasite drag, parasite power only accounts for 0.1% of the total aerodynamic power. The train represented 6.9% of body weight and is expected to increase induced power. The absence of a detectable effect on take-off performance does not necessarily mean that there is no cost associated with possessing such ornate plumage; rather, it suggests that given the variation in take-off performance per se, the magnitude of any effect of the train has little meaningful functional relevance. © 2014.

    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    This study aimed to develop and to characterize fermented dairy beverage formulated with Camellia sinensis. The infusion was elaborated with the addiction of dehydrated leaves of C. sinensis in whey (1g/100g) which added in sweetened milk (10% sucrose w/w) coagulated by Streptococcus salivarius subspecies thermophilus and Lactobacillus delbrueckii subspecies bulgaricus in proportions of 10, 20, 30 and 40% (v/w). The control treatment consisted of yogurt added with sucrose (10% w/w). Analysis were performed to quantify dry mass, moisture, ash, protein, fat, sodium, acidity, total quantification of lactic acid bacteria, total antioxidant activity and viscosity at the initial time of production and at 15 and 30 days of storage. Chromatographic determination of volatile compounds and sensory tests of acceptance and consumption intention were conducted at the initial time of production. Dry matter content, moisture, ash and total count of lactic acid bacteria from fermented milk drink formulations were not significantly affected by the amount of infusion of C. sinensis. However, the content of protein, fat and sodium were significantly lower with the increase of the proportion of infusion incorporated into the product. Significant reduction in apparent viscosity occurs with the increase in the amount of infusion added. The total antioxidant activity of the formulations was significantly higher as higher were the amount of added infusion. The addition of infusion contributed to the diversification of volatile aroma and taste makers in the product. The formulation of fermented dairy drink with addition of 30% infusion C. sinensis was better evaluated in sensory tests, with greater acceptance and greater consumer intent of consumption.

  10. Ethics in the medieval university: the importance of classics reading for the elaboration of Thomas Aquinas

    Full Text Available This paper aims to present some considerations about the importance of reading to the development of the ethics conceptions of Thomas Aquinas (1224 - 5? / 1274. At the dawn of the thirteenth century, the townspeople of Medieval West created a new institution designed for knowledge and education: the University. In it, teachers and disciples were debating key issues for the new society using mainly texts of Ancient Philosophy and Christians, but also Arab and Jewish writings. The literacy forms used encompassed mainly lectio and disputatio , and counteracted by distinct theoretical bases, those thinkers eventually recreated the summa , in a original and fundamental form to the philosophical elaboration of that time. To discuss the importance of reading in the formulation of the concept of ethics in the medieval university, we will present some characteristics of the production of knowledge in the thirteenth century linked to its historical context and then discuss some ethical considerations of Thomas Aquinas, one of the most prominent authors of that period. Considering the limits of this article, only one text, “The object of charity” based on Aquinas major work, the Summa of Theology, will be discussed in depth. Preliminarily, it is possible to state that as well as the reading of classical authors by Thomas Aquinas and other masters of the thirteenth century, helped them develop knowledge about ethics conforming to their time, historical reading of these authors helps in the understanding of today.

    Producer of macrolide antibiotic avermectin Streptomyces avermitilis UCM Ac-2179 has been isolated from Ukrainian chernozem soil, its biosynthetic activity has been increased by the traditional selection and chemical mutagenesis methods. Streptomyces avermitilis UCM Ac-2179 synthesizes avermectin with the content of anti-parasitic B-components more than 40%. Addition of exogenous Na-pyruvate (1.5 mg/L) in cultural medium promotes a 2.5-fold augmentation of the avermectin synthesis. The preparation Avercom has been obtained by the method of ethanol extraction from the producer biomass. This preparation includes antibiotic avermectin and other biologically active substances: free amino acids, lipids, phytohormones. Avercom has high nematicidic activity and raises plant resistance to fungal and viral diseases. On the base of Avercom and plant growth regulators the complex preparations Actinolan and Ascoldia have been elaborated. The effectiveness of the biopreparations as nematicidic and plantstimulating means under experimental and industrial conditions was confirmed.

    Two experiments were conducted to examine whether a misattribution of specific characteristics or a misattribution of global familiarity underlies false memories as assessed through imagination inflation. Using the paradigm developed by Goff and Roediger (1998), we found that the proportion of false memories increased with repeated imagination, replicating the imagination inflation effect. False memories developed through imagination were greatest in conditions that forced participants to include sensory detail in their imaginings. Finally, conscious recollection more often accompanied false memories in perceptually detailed imagination conditions, whereas feelings of familiarity more often accompanied false memories in conditions that lacked sensory cues. These results suggest that imagination that contains more perceptual information leads to more elaborate memory representations containing specific characteristics that can be confused with actually performed actions. Confusion based on these representations, as opposed to confusion based on processing fluency, is more likely to lead to false memories.

    Full Text Available This paper presents an elaborated analysis for investigating the stack-based layering processes during the systems change pathway. The system change pathway is defined as the path resulting from the combinations of all successive changes induced on the system when subjected to varying environments, activities, events, or any excessive internal or external influences and happenings “on and above” its normal stands, situations or set-points during its course of life. The analysis is essentially based on the important overall system paradigm of “Time driven-event driven-parameters change”. Based on this paradigm, it is considered that any affected activity, event or varying environment is intelligently self-recorded inside the system through an incremental consolidity-scaled change in system parameters of the stack-based layering types. Various joint stack-based mathematical and graphical approaches supported by representable case studies are suggested for the identification, extraction, and processing of various stack-based systems changes layering of different classifications and categorizations. Moreover, some selected real life illustrative applications are provided to demonstrate the (infinite stack-based identification and recognition of the change pathway process in the areas of geology, archeology, life sciences, ecology, environmental science, engineering, materials, medicine, biology, sociology, humanities, and other important fields. These case studies and selected applications revealed that there are general similarities of the stack-based layering structures and formations among all the various research fields. Such general similarities clearly demonstrate the global concept of the “fractals-general stacking behavior” of real life systems during their change pathways. Therefore, it is recommended that concentrated efforts should be expedited toward building generic modular stack-based systems or blocks for the mathematical

In order to elaborate different new ceramic products (porous or dense composites the mentioned by-products and illitic clay from two different layers of Apriki deposit (Latvia with illite content in clay fraction up to 80-90% was used as a matrix. The raw materials were investigated by differential-thermal (DTA and XRD analysis. Ternary compositions were prepared from mixtures of 15–35 wt % of sludge, 20 wt % of waste glass and 45–65 wt % of clay and the pressed green bodies were thermally treated in sintering temperature range from 1080 to 1120 ºC in different treatment conditions. Materials produced in temperature range 1090–1100 ºC with the most optimal properties - porosity 38-52%, water absorption 39–47% and bulk density 1.35–1.67 g/cm3 were selected for production of porous ceramics and materials showing porosity 0.35–1.1%, water absorption 0.7–2.6 % and bulk density 2.1–2.3 g/cm3 - for dense ceramic composites. Obtained results indicated that incorporation up to 25 wt % of sewage sludge is beneficial for production of both ceramic products and glass-ceramic composites according to the technological properties. Structural analysis of elaborated composite materials was performed by scanning electron microscopy(SEM. By X-ray diffraction analysis (XRD the quartz, diopside and anorthite crystalline phases were detected.Durante la obtención de ciertas fibras de vidrio se generan dos subproductos o residuos principalmente: Lodo de arcilla montmorillonítica capaz de adsorber el 50 % de materia orgánica y un vidrio silicato alumínico con temperatura de reblandecimiento relativamente alta (> 600 ºC.

  19. Elaborate analogies in science text: Tools for enhancing preservice teachers' knowledge and attitudes

    Paris, Nita A.

    2000-11-01

    The present study consisted of two experiments in which the learners read and studied texts about three fundamentally important science concepts. The learners, who were preservice teachers, read a control text with no analogy, a text with a simple analogy, and a text with an elaborate analogy. An elaborate analogy is one that consists of text and pictorial components in which similarities between the analog and the target concept are made explicit. The findings support the use of elaborate analogies in text for improving the science knowledge and attitudes of preservice teachers by relating familiar ideas to new ideas, thereby increasing the relevance and the comprehensibility of the new ideas. Increasing the relevancy of science text by inclusion of an elaborate analogy had an affective, cognitive, and metacognitive impact on learning. Data were examined either by a univariate analysis of variance for repeated measures or a Friedman's test for related samples. These data were supplemented by participants' qualitative responses which were categorized. The results indicated that elaborate analogies in text increased learners' interest in both the conceptual topic of the text and the text itself. Furthermore, the elaborate analogies enhanced learners' science concept learning and inference-making as well. In addition, elaborate analogies increased learners' metacognitive ability to accurately assess their knowledge of science concepts. Finally, elaborate analogies enhanced preservice teachers' self-efficacy for teaching science. The results are consistent with the view that use of analogies to enhance science attitudes and knowledge is inherently constructive in nature. The present findings suggest that current practices of how preservice teachers learn science should be adapted to take advantage of analogies in a more systematic way. Future researchers should investigate the usefulness of elaborate analogies for enhancing metacognition in domain novices and domain

    The current model of planarian anterior regeneration evokes the establishment of low levels of Wnt signalling at anterior wounds, promoting anterior polarity and subsequent elaboration of anterior fate through the action of the TALE class homeodomain PREP. The classical observation that decapitations positioned anteriorly will regenerate heads more rapidly than posteriorly positioned decapitations was among the first to lead to the proposal of gradients along an anteroposterior (AP) axis in a developmental context. An explicit understanding of this phenomenon is not included in the current model of anterior regeneration. This raises the question what the underlying molecular and cellular basis of this temporal gradient is, whether it can be explained by current models and whether understanding the gradient will shed light on regenerative events. Differences in anterior regeneration rate are established very early after amputation and this gradient is dependent on the activity of Hedgehog (Hh) signalling. Animals induced to produce two tails by either Smed-APC-1(RNAi) or Smed-ptc(RNAi) lose anterior fate but form previously described ectopic anterior brain structures. Later these animals form peri-pharyngeal brain structures, which in Smed-ptc(RNAi) grow out of the body establishing a new A/P axis. Combining double amputation and hydroxyurea treatment with RNAi experiments indicates that early ectopic brain structures are formed by uncommitted stem cells that have progressed through S-phase of the cell cycle at the time of amputation. Our results elaborate on the current simplistic model of both AP axis and brain regeneration. We find evidence of a gradient of hedgehog signalling that promotes posterior fate and temporarily inhibits anterior regeneration. Our data supports a model for anterior brain regeneration with distinct early and later phases of regeneration. Together these insights start to delineate the interplay between discrete existing, new, and then

    Full Text Available The objective of this study was to evaluate the effect of the addition of oatmeal and palm fat in the elaboration of biscuits with added L-leucine and calcium in order to develop a product for sarcopenia in the elderly. The biscuits, or cookies, were elaborated applying a central composite rotational design with surface response methodology, and the significant linear, quadratic and interaction terms were used in the second order mathematical model. Physical, physicochemical and sensory analyses were performed by a trained panel. Based on the best results obtained, three cookie formulations were selected for sensory evaluation by the target group and physicochemical determinations. The formulations with the highest sensory scores for appearance and texture and medium scores for color and expansion index were selected. The addition of calcium and leucine increased significantly the concentration of these components in the biscuits elaborated resulting in a cookie with more than 30% of DRI (Dietary Reference Intake for calcium and leucine. The formulations selected showed high acceptance by the target group; therefore, they can be included in the diet of elderly with sarcopenia as a functional food.

Halfway through the process, the authors present the main points of a document whose preparation testified to a new approach in the policies for national development. Regional discussions that commence this month should give rise to numerous debates, based most particularly on the capacity territorial organisations have to participate in respect to the rational usage and decentralized production of energy. At the time of international negotiations on climatic changes, the questions raised are very quickly becoming inescapable. (authors)

  7. Elaboration by tape-casting and co-sintering of multilayer catalytic membrane reactor- performances

    Julian, A.

    2008-12-01

    This research deals with the increasing interest of the conversion of natural gas into liquid fuels (diesel, kerosene) using the Gas To Liquid (GTL) process. Within this context, Catalytic Membrane-based Reactors (CMR) would allow an improvement of the process efficiency and a reduction of investment and production costs with respect to the present technologies. They allow performing the separation of oxygen from air, and the conversion of natural gas into synthesis gas within a single step. After having highlighted the economical and technological advantages of using a ceramic membrane for the production of syngas (H 2 + CO 2 ), the author describes the protocols of synthesis of powders selected for the dense membrane and the porous support, and their physical characteristics. The obtained powders are then adapted to the tape-casting forming process. Graded-composition multilayer structures and microstructure are then elaborated by co-sintering. Performances in terms of membrane oxygen flows are presented. Mechanisms limiting the oxygen flow are discussed in order to propose ways of improving membrane performances. The limits of the studied system are defined in terms of elastic properties, and optimization ways are proposed for the dense membrane material composition in terms of mechanical properties and performance in oxygen semi-permeation

    The purpose of this study was to use the categorization-elaboration model (CEM) to examine the asymmetrical effects of goal faultlines in groups, which are present when hypothetical dividing lines are created on the basis of different performance goals, splitting the group into subgroups. On the basis of the CEM, we expected groups with goal faultlines to exhibit higher levels of creative task performance than (a) groups with specific, difficult goals and (b) groups with do-your-best goals. We expected the benefits of goal faultlines to be due to increases in reflective reframing, which occurs when group members build on each other's ideas by shifting to alternate frames. However, we expected groups with goal faultlines to exhibit lower levels of routine task performance than (a) groups with do-your-best goals and (b) groups with specific, difficult goals, due to increased perceptions of loafing. Results from 87 groups generally supported our hypothesized model. Implications are discussed as well as possible limitations and directions for future research. (c) 2013 APA, all rights reserved.

    2017-01-01

    This article elaborates on the hazards of spiritual history taking. It provides expert insights to consider before entering the field. In summer 2012, a group of spiritual care experts were invited to discuss the complexity of taking spiritual histories in a manner of hermeneutic circle. Thematic analysis was applied to define the emerging themes. The results demonstrate that taking a spiritual history is a complex and challenging task, requiring a number of personal qualities of the interviewer, such as 'being present', 'not only hearing, but listening', 'understanding the message beyond the words uttered', and 'picking up the words to respond'. To 'establish a link of sharing', the interviewer is expected 'to go beyond the ethical stance of neutrality'. The latter may cause several dilemmas, such as 'fear of causing more problems', 'not daring to take it further', and above all, 'being ambivalent about one's role'. Interviewer has to be careful in terms of the 'patient's vulnerability'. To avoid causing harm, it is essential to propose 'a follow-up contract' that allows responding to 'patient's yearning for genuine care'. These findings combined with available literature suggest that the quality of spiritual history taking will remain poor unless the health-care professionals revise the meaning of spirituality and the art of caring on individual level.

    This work is a part of the studies about the elaboration of reference radioactive sources, which are done in the National Institute of Nuclear Research in Mexico. Specially concerns with the elaboration of α-β radioactive sources. The importance of this work is because their applications increase day by day. Medicine, engineering, agriculture and even the arts cannot escape to the influence and impact of the nuclear sciences. But, what are the radioactive sources?, what is a holder of a radioactive source?, why we elaborate holders with special materials?, which is the best technique to elaborate them?. These topics are commented in this work. The material is as follows: the introduction and objective are described in chapter one. The second chapter deals with concepts about atomic and molecular structures, general description of nuclear radiation and their characteristics, comments about radioactive law decay, interaction of the alpha particles with the matter and a short description about surface barrier detectors. The different methods for elaborate a radioactive source holders are described in the chapter three. This same chapter speaks the topic about the elaboration of vyns or cellulose films and a device is proposed for make them; are some methods described how to take measure of their thickness. Chapter four shows the results, analysis and the respective conclusions. (Author)

    2017-06-01

    Full Text Available The Mīmāṃsā school of Indian philosophy elaborated complex ways of interpreting the prescriptive portions of the Vedic sacred texts. The present article is the result of the collaboration of a group of scholars of logic, computer science, European philosophy and Indian philosophy and aims at the individuation and analysis of the deontic system which is applied but never explicitly discussed in Mīmāṃsā texts. The article outlines the basic distinction between three sorts of principles —hermeneutic, linguistic and deontic. It proposes a mathematical formalization of the deontic principles and uses it to discuss a well-known example of seemingly conflicting statements, namely the prescription to undertake the malefic Śyena sacrifice and the prohibition to perform any harm.

    Chinese herbal medicine (CHM) formulas are the major components of traditional Chinese medicine (TCM) interventions. The general reporting quality of randomized controlled trials (RCTs) of CHM formulas is disappointing, although CONSORT (Consolidated Standards of Reporting Trials) Statement extensions for herbal medicinal interventions and acupuncture interventions are available. A group of TCM clinical experts, methodologists, epidemiologists, and editors has developed this CONSORT Extension for CHM Formulas (CONSORT-CHM Formulas 2017) through a comprehensive process, including publication of the draft version, solicitation of comments, revision, and finalization. The CONSORT 2010 Statement was extended by introducing the idea of TCM Pattern and the features of CHM formulas. One new checklist subitem, keywords, was added to facilitate indexing and data searching. Seven of the 25 CONSORT checklist items, namely title and abstract, background and objectives, participants, interventions, outcomes, generalizability, and interpretation, are now elaborated, and the explanation of harms specific to CHM formulas is revised. Illustrative examples and explanations are also provided. The group hopes that CONSORT-CHM Formulas 2017 can improve the reporting quality of RCTs of CHM formulas.

    Social skills refer to a wide group of abilities that allow us to interact and communicate with others. Children learn how to solve social situations by predicting and understanding other's behaviors. The way in which humans learn to interact successfully with others encompasses a complex interaction between neural, behavioral, and environmental elements. These have a role in the accomplishment of positive developmental outcomes, including peer acceptance, academic achievement, and mental health. All these social abilities depend on widespread brain networks that are recently being studied by neuroscience. In this paper, we will first review the studies on this topic, aiming to clarify the behavioral and neural mechanisms related to the acquisition of social skills during infancy and their appearance in time. Second, we will briefly describe how developmental diseases like Autism Spectrum Disorders (ASD) can inform about the neurobiological mechanisms of social skills. We finally sketch a general framework for the elaboration of cognitive models in order to facilitate the comprehension of human social development. PMID:26483621

    The Large program (Intermediate MAss Galaxy Evolution Sequence, IMAGES) aims at measuring the velocity fields of a representative sample of 100 massive galaxies at z=0.4-0.75, taken from the CDFS, the CFRS and the HDFS fields. It uses the unique mode of multiple integral field units of FLAMES/GIRAFFE at VLT. The resolved kinematics data allow to sample the large scale motions at few kpc scale for each individual galaxy. They have been combined with the deepest HST/ACS, Spitzer (MIPS and IRAC) and VLT/FORS2 ever achieved observations. Most intermediate redshift galaxies show anomalous velocity fields implying that, 6 Gyrs ago, half of the present day spirals were out of equilibrium and have peculiar morphologies. The wealth of data in these fields allows to modelize the physical processes in each galaxy with an accuracy almost similar to what is done in the local Universe. These detailed analyses reveal the importance of merger processes, including their remnant phases. It points out the importance of disk survival and it supports the disk rebuilding scenario, suggesting that the hierarchical scenario may apply to the elaboration of disk galaxies as well as it does for ellipticals.

    The IMAGES (Intermediate MAss Galaxy Evolution Sequence) project aims at measuring the velocity fields of a representative sample of 100 massive galaxies at z=0.4-0.75, selected in the CDFS, the CFRS and the HDFS fields. It uses the world-unique mode of multiple integral field units of FLAMES/ GIRAFFE at VLT. The resolved-kinematics data allow us to sample the large scale motions at ˜ few kpc scale for each galaxy. They have been combined with the deepest HST/ACS, Spitzer (MIPS and IRAC) and VLT/FORS2 ever achieved observations. Most intermediate redshift galaxies show anomalous velocity fields: 6 Gyrs ago, half of the present day spirals were out of equilibrium and had peculiar morphologies. The wealth of the data in these fields allow us to modelize the physical processes in each galaxy with an accuracy almost similar to what is done in the local Universe. These detailed analyses reveal the importance of merger processes, including their remnant phases. Together with the large evolution of spiral properties, this points out the importance of disk survival and strengthens the disk rebuilding scenario. This suggests that the hierarchical scenario may apply to the elaboration of disk galaxies as it does for ellipticals.

    General practitioner is used to be consulted by teenagers who have already had suicide ideas or attempted suicide and who were not been taking care for. The most of the time the GP doesn't know their antecedents; but as they are at risk to do it again, it's important to detect them. To elaborate and to validate a test to detect teenagers' suicide behaviour. After participating to a survey (Lycoll) which included 3 872 teenagers, 17 GPs and 3 psychiatrists (ADOC) created a screening test to be used by GPs. It was a questionnaire, named TSTS, with 4 questions completed by 5 items to explore the troubles' severity. Then, this test has been experienced among 38 GPs who didn't know it before. This study has been done as a clinical audit. Each physician has been visited by a research clinical assistant who had been taught for it, to estimate the screening of suicide ideas or attempted suicide before and after taking knowledge of the test. Results indicate a very good acceptability of this screening tool which has been used for 60% of teenagers' office visits. It allowed to guide a large number of visits towards preoccupations which were different from the initial one and to detect suicide antecedents among 13% teenagers "tested" among whom 2/3 had already seen a GP. This test is recommended to GPs in usual practice to detect teenagers at suicide risk.

    SiAlON-BN are materials able to replace carbon refractories used in steel-making shop, especially for low carbon steels elaboration. Two family of composites are studied: Si{sub 3}N{sub 4}-BN obtained by hot compression, and SiAlON-BN by natural sintering. In the first case, an organic precursor of BN which seems to activate the sintering process was also used. For all these materials, we studied elaboration processes, microstructures, mechanical properties, and thermal shocks, oxidation and corrosion resistances by liquid iron. BN presence lowers mechanical properties, but increases thermal shock and oxidation resistance at high temperature. From all the sintering add-on, Y{sub 2}O{sub 3}, Nd{sub 2}O{sub 3}, La{sub 2}O{sub 3}, CeO{sub 2}, neodymium and lanthanum oxides seems to give a light improvement of high temperature resistance.

    Of the 3 main currents of literature seeking to explain adolescent pregnancy, the medical and demographic currents have essentially produced descriptions of behaviors, attitudes, and opinions, while the psychological current has produced primarily hypotheses interpreting sexual and contraceptive behavior in terms of predispositions. This work seeks to develop an explanatory framework for adolescent sexual and contraceptive behavior in which situational variables would be included. The explanatory variables utilized in the framework were informative and sociological variables, beliefs associated with side effects of contraceptive methods, social support for contraceptive use, norms associated with heterosexual behavior, ability to foresee future consequences, future prospects, perceptions of pregnancy and its consequences, and evaluation of the risk of pregnancy. A semiclosed questionnaire exploring the different model variables was orally administered to 186 female secondary school students in Liege, France. The data were subjected to a discriminant function analysis which permitted assessment of the role of each explanatory variable in determining contraceptive behavior. 53% of the respondents did not use contraception. 91% of those using contraception used pills. 5 types of contraceptive behavior were noted: 1) 20% of the sample were sexually active and had always used contraception 2) 20% were sexually active and used contraception but had not always done so 3) 13% were sexually active but had never used contraception 4) 40% were not sexually active and did not use contraception, and 5) 7% were not sexually active but used a contraceptive. The variables explained 75% of the difference between adolescents who used and did not use contraception, and 39% of the difference between adolescents ever exposed to risk of pregnancy or never exposed. The principle variables explaining use or nonuse of contraception were stated in declining order of importance. Girls having

    We report on the crystal structure, microstructure and magnetic properties of Ni nanoparticles (NPs), with an average diameter of around 40 nm, produced by hydrothermal method. A series of Ni powders was synthesized at relatively low temperature (140 °C) by varying the NaOH concentration. The crystal structure, microstructure and magnetic properties were investigated by means of XRD, MEB coupled to EDX and VSM magnetometry. The XRD patterns show Bragg reflections corresponding to Ni with face centred cubic (fcc) crystal structure. EDX spectra confirm the purity of Ni powders. Moreover, the SEM micrographs show that the Ni-NPs are agglomerated forming entities of 1–5 μm in average size with different morphologies that change as the NaOH concentration increases. While those entities exhibit a flower-like form at the lowest concentration, a dendritic shape appears for the highest one. The room temperature values for the coercive field ( 2 /kg) were obtained from the magnetic hysteresis loops. We discuss about the influence of the particle morphology on the magnetic behaviour. - Highlights: • High purity Ni nanoparticles have been elaborated by hydrothermal method under the presence of sodium hydroxide with different concentrations. • The variation of the NaOH concentration seems to be irrelevant for the NP size, but plays an important role in the morphology. • The shape of Ni nanoparticles changes from spherical cores to flower-like entities and then to dendritic ones as the NaOH concentration increases. • The coercive field depends on the shape of nanoparticles

  11. Emission trading: A discussion paper

    International Nuclear Information System (INIS)

    1992-05-01

    Emission trading is a market-based incentive program designed to control air emissions in which a cap is placed on the total quantity of pollutants allowed to be emitted in an airshed. Appropriate shares of this amount are allocated among participating emission sources, and participants can buy or sell their shares. Advantages of emission trading include its potential to achieve air emission targets at a lower cost than the traditional command and control approach, and its ability to accommodate economic growth without compromising environmental quality. A study was conducted to evaluate the potential use of emission trading programs to achieve emission reduction goals set for nitrogen oxides, volatile organic compounds (VOC), and sulfur oxides. Emission trading programs in the USA are reviewed and a set of factors important for the success of emission trading are identified. Key policy and design issues related to an emission trading program are identified, explained, and discussed. Administrative issues are then analyzed, such as legislative authority, monitoring and enforcement requirements, and trading between jurisdictions. A preliminary assessment of emission trading for control of NOx and VOC in the Lower Fraser Valley indicates that emission trading would be feasible, but legislative authority to implement such a program would have to be introduced

    Two different geostatistical approaches for the elaboration of groundwater quality maps are presented. Firstly, the main theoretical aspects concerning to the two estimation methods used, ordinary kriging and indicator kriging, are described. They share a common theoretical basis but focus their estimations in different terms. The former gives the most probable value of a groundwater quality parameter in the aquifer, e. g. nitrate contents, so that is applied to map it spatial distribution. Whereas the latter estimates is applied to estimate the spatial probability distribution function of surpassing a given threshold or alert value for the experimental parameter. A case study regarding the Vega of Granada aquifer is also presented. The comparative advantages offered by each of these methods are discussed, taking into account the random behaviour shown by the studied variable. It is concluded that maps created by both methods provide value information of great interest for decision-making with regards to water quality control. (Author) 10 refs.

    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

    2011-01-01

    This discourse analysis study focuses on the dominant voices in a preservice teacher discussion group in a language variation course included in a teacher education program. The voices in the discussion group have what Bakhtin (1981) considers heteroglossic characteristics and what Kristeva (1986) calls intertextuality and what Fairclough (1992) considers interdiscursivity. The analysis of the voices shows textualized voices, that include appropriated voices from mentors or previous teachers ...

  18. A framework for elaborating a geological disposal safety case: Main issues to be addressed

    International Nuclear Information System (INIS)

    Besnus, F.; Gay, D.

    2002-01-01

    International guidance on safety standards for the geological disposal of radioactive waste is being elaborated by IAEA. A comparison of experiences acquired in developing deep repository projects shows that many important issues related to the progressive building of confidence in the safety demonstration of such facilities are commonly addressed by the various organisations involved in radioactive waste management. However, there is still some discrepancies in defining the steps that form the staged elaboration of a safety case. This paper intends to propose a framework for defining the safety case in describing the main issues to be addressed and highlighting questions of consistency between former steps. (author)

  19. Nonlinear generalized synchronization of chaotic systems by pure error dynamics and elaborate nondiagonal Lyapunov function

    Ge Zhengming; Chang Chingming

    2009-01-01

    By applying pure error dynamics and elaborate nondiagonal Lyapunov function, the nonlinear generalized synchronization is studied in this paper. Instead of current mixed error dynamics in which master state variables and slave state variables are presented, the nonlinear generalized synchronization can be obtained by pure error dynamics without auxiliary numerical simulation. The elaborate nondiagonal Lyapunov function is applied rather than current monotonous square sum Lyapunov function deeply weakening the powerfulness of Lyapunov direct method. Both autonomous and nonautonomous double Mathieu systems are used as examples with numerical simulations.

    A laboratory system for fully automatic elaboration of chip breaking diagrams has been developed and tested. The system is based on automatic chip breaking detection by frequency analysis of cutting forces in connection with programming of a CNC-lathe to scan different feeds, speeds and cutting...... depths. An evaluation of the system based on a total of 1671 experiments has shown that unfavourable snarled chips can be detected with 98% certainty which indeed makes the system a valuable tool in chip breakability tests. Using the system, chip breaking diagrams can be elaborated with a previously...

    2017-05-01

    People often discuss events they have seen and these discussions can influence later recollections. We investigated the effects of factual, emotional, and free retelling discussion on memory recollections of individuals who have witnessed an event. Participants were shown a video, made an initial individual recall, participated in one of the three retelling conditions (emotional versus factual versus free) or a control condition, and then recalled the event individually again. Participants in the factual and free retelling conditions reported more items not previously recalled than participants in the control condition did, while the emotional condition did not show the same advantage. Participants in all three retelling conditions failed to report more previously recalled items as compared with the control condition. Finally, a memory conformity effect was observed for all three retelling conditions. These findings suggest that eyewitnesses' discussions may influence the accuracy of subsequent memory reports, especially when these discussions are focused on emotional details and thoughts.

  2. Ethical considerations in protecting the environment from the effects of ionizing radiation. A report for discussion

    International Nuclear Information System (INIS)

    2002-02-01

    In recent years awareness of the vulnerability of the environment has increased and the need to protect it against the effects of industrial pollutants has been recognized. This trend is reflected in new and developing international policies for environmental protection. In the context of protection of the environment against ionizing radiation, the existing international approach is based on providing for the protection of humans. The current recommendations of the International Commission on Radiological Protection (ICRP) include the statement that t he standard of environmental control needed to protect man to the degree currently thought desirable will ensure that other species are not put at risk... . In the light of the new focus of concern for the environment, this statement is being critically reviewed in several international fora. The IAEA has, over many years, sponsored studies of the effects of ionizing radiation on species other than humans. Most recently it published a discussion report as IAEA-TECDOC-1091 (1999) in which the need for developing a system for protecting the environment against the effects of ionizing radiation was elaborated and in which various related technical and philosophical issues for resolution were discussed. The current report explores the ethical principles that could underlie a system of environmental protection. It is intended as one step in the development of a framework for the protection of the environment from the effects of ionizing radiation, and is being published in order to promote awareness of the current developments in this field as well as to encourage discussion amongst those involved

  5. Methodological challenges in qualitative content analysis: A discussion paper.

    Science.gov (United States)

    Graneheim, Ulla H; Lindgren, Britt-Marie; Lundman, Berit

    2017-09-01

    This discussion paper is aimed to map content analysis in the qualitative paradigm and explore common methodological challenges. We discuss phenomenological descriptions of manifest content and hermeneutical interpretations of latent content. We demonstrate inductive, deductive, and abductive approaches to qualitative content analysis, and elaborate on the level of abstraction and degree of interpretation used in constructing categories, descriptive themes, and themes of meaning. With increased abstraction and interpretation comes an increased challenge to demonstrate the credibility and authenticity of the analysis. A key issue is to show the logic in how categories and themes are abstracted, interpreted, and connected to the aim and to each other. Qualitative content analysis is an autonomous method and can be used at varying levels of abstraction and interpretation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Klein, Nadav; Epley, Nicholas

    2015-06-16

    Groups of individuals can sometimes make more accurate judgments than the average individual could make alone. We tested whether this group advantage extends to lie detection, an exceptionally challenging judgment with accuracy rates rarely exceeding chance. In four experiments, we find that groups are consistently more accurate than individuals in distinguishing truths from lies, an effect that comes primarily from an increased ability to correctly identify when a person is lying. These experiments demonstrate that the group advantage in lie detection comes through the process of group discussion, and is not a product of aggregating individual opinions (a "wisdom-of-crowds" effect) or of altering response biases (such as reducing the "truth bias"). Interventions to improve lie detection typically focus on improving individual judgment, a costly and generally ineffective endeavor. Our findings suggest a cheap and simple synergistic approach of enabling group discussion before rendering a judgment.

    Takeuchi, Mitsuo

    2008-01-01

    In December 2007, the Forum on Stakeholder Confidence discussed its theme entitled 'Link between research, development and demonstration (RD and D) and stakeholder confidence'. It was remarked that regulators need a technical demonstration to aid in evaluating the safety case. Local stakeholders appreciate the opportunity to visualise technological arrangements. In both cases, demonstration adds to confidence in the feasibility of solutions. Some believe there is an important role for analogues in communication with stakeholders, if handled with integrity. To explore and benchmark current practices, it was decided to hold a topical session at the 9. regular meeting of the FSC on 4 June 2008 regarding the use of analogues for confidence building. The session opened with an introductory presentation by the session rapporteur. This incorporated input provided for the purpose by FSC members in cooperation with their country's representative to the NEA RWMC 'Integration Group on the Safety Case'. Three speakers then presented the various uses of analogues by implementers, regulators and scientists to build their own confidence; a fourth speaker dealt with the experience of using natural analogues in public information. The presentations addressed the use of analogues in the field of geological disposal of high-level waste (HLW) and long-lived intermediate level (ILW-LL) radioactive waste. Then the FSC participants split into two working groups for discussion. The outcome of these discussions was reported in plenary on 6 June 2008 and it was agreed to publish proceedings of the session. The present summary, prepared by the session rapporteur with input from the NEA Secretariat, captures the main points heard in the course of the event. It combines data from the formal presentations and remarks made in discussion. The latter represent viewpoints expressed by a group whose primary focus is not natural analogues but rather stakeholder interests. The

    Full Text Available Elaboration Likelihood Model (ELM, which supports the existence of two routes to persuasion: central and peripheral routes, has been one of the major models on persuasion. As the number of studies in the Turkish literature on ELM is limited, a detailed explanation of the model together with a comprehensive literature review was considered to be contributory for this gap. The findings of the review reveal that the model was mostly used in marketing and advertising researches, that the concept most frequently used in elaboration process was involvement, and that argument quality and endorser credibility were the factors most often employed in measuring their effect on the dependant variables. The review provides valuable insights as it presents a holistic view of the model and the variables used in the model.

    Attitude change toward body image: The role of elaboration on attitude strength. Attitudes toward body image have been shown to play a central role in the understanding and treating of eating disorders. In the present research, participants' attitudes toward their body image were changed through a persuasive procedure involving high mental elaboration (self-persuasion) or through a less engaging procedure involving less active participation (passive exposure). As expected, participants in these two groups showed more favourable attitudes toward their bodies than those in the control group. Despite that both treatments were equally efficient in changing attitudes, the strength associated with those attitudes was significantly different depending on the amount of thinking involved in the process of change. Specifically, attitudes were stronger in the high rather than low thinking group of treatment. This finding is important because the strength of the attitude may determine the long-term consequences of an intervention.

    Definitions of related concepts (e.g., genotype - phenotype ) are prevalent in introductory classes. Consequently, it is important that educators and students know which strategy(s) work best for learning them. This study showed that a new comparative elaboration strategy, called differential-associative processing, was better for learning definitions of related concepts than was an integrative elaborative strategy, called example elaboration. This outcome occurred even though example elaboration was administered in a naturalistic way (Experiment 1) and students spent more time in the example elaboration condition learning (Experiments 1, 2, 3), and generating pieces of information about the concepts (Experiments 2 and 3). Further, with unrelated concepts ( morpheme-fluid intelligence ), performance was similar regardless if students used differential-associative processing or example elaboration (Experiment 3). Taken as a whole, these results suggest that differential-associative processing is better than example elaboration for learning definitions of related concepts and is as good as example elaboration for learning definitions of unrelated concepts.

    Transthyretin-related amyloidosis (ATTR) is an autosomal dominant disease affecting the peripheral and autonomic nervous system, heart, eyes and kidneys. It is the most disabling hereditary polyneuropathy in adults. The French National Reference centre for this disease was accredited in 2005 with 10 lines of action. One of them is to inform and educate patients about their disease to improve their care and reduce morbidities. We thus decided to elaborate a therapeutic patient education (TPE) programme, starting with patients' needs assessment. A qualitative research study was conducted with one-to-one semi-structured interviews of selected individuals. Recorded interviews were analysed to identify the skills that patients need to acquire. A TPE programme was elaborated on the basis of these findings. Seven patients, one asymptomatic carrier and two healthy spouses were interviewed. Analysis of the interviews showed that interviewees had a good knowledge of the disease and its symptoms but they had difficulties explaining the disease mechanism and did not have an adequate knowledge of the available treatment options, although they knew that liver transplant might halt progression of the disease. ATTR amyloidosis appeared to have a major negative impact on the patient's physical and mental well-being. Patients feared loss of autonomy and having to require assistance from their relatives and spouses. All interviewees were keen to participate in a TPE programme. Based on this needs assessment, we identified seven skills that patients need to acquire and several pedagogical goals to be achieved during the education programme. An interdisciplinary team then elaborated a complete TPE programme. Elaboration of a TPE programme for ATTR amyloidosis required to obtain useful information from the patients themselves, and their relatives, concerning their perception of their disease. This needs' assessment constituted the basis for designing the first TPE programme, to our

    In the laboratory of radioactive standards they have been come manufacturing punctual sources gauged gamma emitting during several years. Before the demand of extended radioactive homogeneous sources of beta particles emitting, in particular with nuclides that are simultaneously gamma and beta emitting, it was designed a procedure for it elaboration based on the one that we use at the moment for the elaboration of the punctual gamma sources. This procedure consists on the integration of a compact group of this type of sources on a single extended support, sealed one of its faces with a film of transparent material in satisfactory grade to the beta particles. In this work this procedure is described and it is applied in the elaboration of two sources that its were requested by the Laguna Verde Central (CFE), one with area of 20 cm 2 and the other one of 100 cm 2 . The homogeneity, measure as the dispersion of the activities of the aliquot ones distributed in the active surfaces was inside 2%. The percentage of attenuation of the beta particles was also measured by the film (window) with the one that the sources were sealed. (Author)

    The increasing demand for high-fiber products has favored the design of numerous bakery products rich in fiber such as bread, cookies, and cakes. The objective of this study was to evaluate the dietary fiber and estimated glycemic index of cookies containing extruded wheat bran. Wheat bran was subjected to extrusion process under three temperature profiles: TP1;(60, 75, 85 and 100 °C), TP2;(60, 80, 100 and 120 °C), and TP3;(60, 80, 110 and 140 °C) and three moisture contents: (15, 23, and 31 %). Cookies were elaborated using extruded wheat bran (30 %), separated into two fractions (coarse and fine). The dietary fiber content of cookies elaborated with extruded wheat bran was higher than the controls; C0 (100 % wheat flour) and C1 (30 % of no extruded bran coarse fraction) and C2 (30 % of no extruded bran fine fraction). The higher values of dietary fiber were observed on cookies from treatments 5 (TP1, 31 % moisture content and coarse fraction) and 11 (TP2, 31 % moisture content and coarse fraction). The estimated glycemic index of cookies ranged from 68.54 to 80.16. The dietary fiber content of cookies was increased and the lowest glycemic index corresponded to the cookies elaborated with extruded wheat bran. Cookie made with the treatment 11 had a better dietary fiber content and lower estimated glycemic index.

    Twenty undergraduate students participated in an elaborative learning test to evaluate the relationship between electrical brain activity and subsequently recalled and not-recalled words. Data collected from the midline (Fz, Cz, Pz) and lateral scalp sites (F3, F4, C3, C4, P3, P4) were analysed. The difference between event-related potentials (ERPs) elicited by subsequently recalled and not-recalled words, the ERP memory effect, was evaluated for each portion (primacy, plateau and recency) of the serial-position curve (SPC). We compared peak amplitudes for the P1, N1, P2, N400, P3 and frontal positive slow wave (FPSW) components. The electrophysiological data support the hypothesis that different mechanisms underlie primacy and recency effects during free recall paradigms. There was no support for the hypothesis that an association arises between memory and the FPSW when subjects utilise elaborative learning strategies. The P2 component predicted subsequent recall at the primacy portion of the SPC, and P1 predicted recall at the primacy and plateau portions of the curve. The findings suggest that the early positive components of the ERP (i.e. P1 and P2) are useful indices of the differential stimulus processing during elaborative learning which predicts later recall.

    2010-01-01

    The specific signatures of α-Al 2 O 3 by Fourier transform infrared (FTIR) spectroscopy were investigated to estimate the intrinsic stress in this compound according to its elaboration mode. Thus, α-alumina was prepared either by calcination of boehmite or gibbsite and also generated by oxidation of a metallic FeCrAl alloy. FTIR results were mainly supported by X-ray diffraction (XRD) patterns that allowed to determine the crystallite size and the strain in the various alpha aluminas. Moreover, the infrared peak at 378.7 cm -1 was used as a reference for stress free α-alumina and the shift of this peak allowed to estimate intrinsic stresses, which were related to the morphology and to the specific surface area of aluminas according to their elaboration mode. These interpretations were confirmed by results obtained by cathodoluminescence experiments. - Graphical abstract: The infrared peak at 378.7 cm -1 was used as a reference for stress free α-alumina and the shift of this peak allowed to estimate intrinsic stresses, which were related to the morphology and to the specific surface area of aluminas according to their elaboration mode.

    2008-01-01

    Effective leadership can be defined in many ways and is an essential element of successful organisations; poor leadership can result in problems such as low staff morale, high staff turnover and reduced productivity. Effective leadership behaviours are well documented in the literature and various leadership models have been proposed that illustrate these behaviours. This discussion paper does not focus on any particular model. Instead it considers the 'Leadership Qualities Framework' which was developed specifically for use within the UK National Health Service. This framework draws upon a range of leadership models and as such it gives a broad indication of leadership behaviours. The framework comprises three components - 'personal qualities', 'setting direction' and 'delivering the service'. This paper commences with an argument as to why effective leadership is important in organisations generally, and specifically within healthcare organisations. Various examples of leadership are illustrated from within and outside the NHS in order to demonstrate effective leadership behaviours. The Leadership Qualities Framework is then examined, along with scenarios to illustrate effective leadership behaviours in context (i.e. within a healthcare organisation). Subsequent reflections on the scenarios aim to identify leadership behaviours that are explained within the framework. The final element of this paper draws on [limited] published evidence of where consultant radiographers have demonstrated effective leadership behaviours. In this section the published evidence is examined and reflected upon. At the end of the article we indicate additional reading for those who wish to further develop their theoretical and practical leadership skills

    In this investigation, preschool-aged children experienced a staged event about which their mothers received misinformation suggesting that their children witnessed an activity that did not occur. Later, mothers were asked to talk about this event with their children. Consistent with previous research, mothers' provision of structure (defined as elaborative questions and statements) and degree of control (defined in terms of functional control of conversational turns) emerged as separate dimensions of maternal memory sharing style. When later interviewed by an unfamiliar examiner about the event, children whose mothers demonstrated both high structure and high control provided the highest levels of false reports of the activity suggested to mothers and generously embellished their accounts of this activity with nonoccurring details. In contrast, children with mothers who provided low structure, regardless of their degree of control, made few false reports and used sparse narrative detail. The implications of these findings for children's memory and suggestibility are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    Platinum nanoparticle-based strain gauges are elaborated by means of atomic layer deposition on flexible polyimide substrates. Their electro-mechanical response is tested under mechanical bending in both buckling and conformational contact configurations. A maximum gauge factor of 70 is reached at a strain level of 0.5%. Although the exponential dependence of the gauge resistance on strain is attributed to the tunneling effect, it is shown that the majority of the junctions between adjacent Pt nanoparticles are in a short circuit state. Finally, we demonstrate the feasibility of an all-plastic pressure sensor integrating Pt nanoparticle-based strain gauges in a Wheatstone bridge configuration.

    Nowadays the daily amount of wastes generated in the world is enormous. There are several categories of wastes with specific characteristics, some of them hazardous. These features, when associated with not properly waste disposal can put at risk both life quality and natural resources of present-day as well as future generations. From 10% to 25% of the wastes generated by health care facilities require special handling care due to their physical, biological, chemical, or radiological characteristics. This requires, among other things, the implementation of specific measures for their environmentally safe management. These measures shall be provided in a formal document, named Health care Waste Management Plan, which shall be written by all health care providers. In Brazil, general guides for elaboration of these documents are well defined by regulatory bodies and technical advices. At federal level, these directives are given by the following organizations: National Health Surveillance Agency - ANVISA, National Council for the Environment - CONAMA, and Brazilian Nuclear Energy Commission - CNEN. At CDTN (Center of Nuclear Technology Development), as part of a doctoral thesis at State University of Campinas (UNICAMP), a methodology that systematizes the management of the several activities involved with hazardous and radioactive wastes was developed, in order to be used as a guidance tool for this task. The objective of this present work is to adapt this methodology to health care waste management and present a conceptual design of a semi-expert system to help the elaboration of Health care Waste Management Plans.

    This study reports the formation of 2-furomethyl-amino acids (2-FM-AA) as indicators of Maillard reaction (MR) in black garlic elaboration, followed by the determination of furosine by ion-pair RP-HPLC-UV. The method was assessed for accuracy, repeatability and detection and quantitation limits indicating its adequacy. Traditional procedure of black garlic obtainment and the inclusion of convective drying (CDP) and ohmic heating (OHP) were assayed. For comparison purposes, three commercial black garlic samples were used. Together with furosine (2-FM-lysine), 2-furoylmethyl-γ-aminobutyric acid and 2-FM-arginine were detected. Levels of furosine were higher in CDP (46.6-110.1mg/100g protein) than in OHP (13.7-42.0mg/100g protein) samples, probably due to the most severe processing conditions used in the former. These results highlight the suitability of 2-FM-AA as chemical indicators to monitor the process of black garlic elaboration in order to obtain high quality products. Copyright © 2017 Elsevier Ltd.

  13. Effects of self-schema elaboration on affective and cognitive reactions to self-relevant information.

    Science.gov (United States)

    Petersen, L E; Stahlberg, D; Dauenheimer, D

    2000-02-01

    The basic assumption of the integrative self-schema model (ISSM; L.-E. Petersen, 1994; L.-E. Petersen, D. Stahlberg, & D. Dauenheimer, 1996; D. Stahlberg, L.-E. Petersen, & D. Dauenheimer, 1994, 1999) is that self-schema elaboration (schematic vs. aschematic) affects reactions to self-relevant information. This assumption is based on the idea that schematic dimensions occupy a more central position in the cognitive system than aschematic dimensions. In the first study, this basic prediction could be clearly confirmed: The results showed that schematic dimensions possessed stronger cognitive associations with other self-relevant cognitions as well as a higher resistance to change than aschematic dimensions did. In the second study, the main assumptions of the ISSM concerning the affective and cognitive reactions to self-relevant feedback were tested: The ISSM proposes that, on schematic dimensions, reactions to self-relevant feedback will most likely follow principles of self-consistency theory, whereas on aschematic dimensions positive feedback should elicit the most positive reactions that self-enhancement theory would predict. The experimental results clearly confirmed the hypotheses derived from the ISSM for affective reactions. Cognitive reactions, however, were in line with self-consistency principles and were not modified by the elaboration of the self-schema dimension involved.

    Solar energy is the most promising and powerful energy source among renewable energies. Photovoltaic electricity is obtained by direct transformation of the sunlight into electricity by means of photovoltaic cells. The objective of this work is to develop photovoltaic cells with back inter-digitated contacts. In the first chapter, we recall the principle of operation and the fundamental parameters of a photovoltaic cell. In a second part, we explain specificities of the inter-digitated back-contact solar cells, as well as the advantages and the disadvantages of such cells. In the second chapter we study the operation of inter-digitated back-contacts solar cells by two dimensional numerical simulation in order to optimize the geometry and doping profiles of the cell. The third chapter relates to the techniques and the methods of characterization of photovoltaic devices and components. In the fourth chapter, we describe the elaboration of inter-digitated back-contact cells. Three technological processes are presented in order to develop a simple technology for cells realization. In particular, we develop the auto-aligned technological process, which enables to elaborate the cells by using only one lithography step. In the last chapter we examine various approaches to reduce the surface recombination: SiO 2 , silicon nitride deposited by UVCVD, hydrogen annealing, etc.. (author)

    Article 10(1) of the EU Biocidal Products Directive 98/8/EC (BPD) requires that for the inclusion of an active substance in Annex I, Annex IA or IB, cumulation effects from the use of biocidal products containing the same active substance shall be taken into account, where relevant. The study proves the feasibility of a technical realisation of Article 10(1) of the BPD and elaborates a first concept for the cumulative environmental exposure assessment of biocides. Existing requirements concerning cumulative assessments in other regulatory frameworks have been evaluated and their applicability for biocides has been examined. Technical terms and definitions used in this context were documented with the aim to harmonise terminology with other frameworks and to set up a precise definition within the BPD. Furthermore, application conditions of biocidal products have been analysed to find out for which cumulative exposure assessments may be relevant. Different parameters were identified which might serve as indicators for the relevance of cumulative exposure assessments. These indicators were then integrated in a flow chart by means of which the relevance of cumulative exposure assessments can be checked. Finally, proposals for the technical performance of cumulative exposure assessments within the Review Programme have been elaborated with the aim to bring the results of the project into the upcoming development and harmonization processes on EU level.

    The effect of taro flour, xanthosoma, cassava and rice, their possible mixtures and two different percentages of egg protein in cupcakes with total substitution of wheat flour are studied. Flours of xanthosoma and taro were elaborated and have utilized flours of cassava and rice existing in market. The moisture was evaluated and found that taro flour presents a lower water content compared to rice flour, xanthosoma and cassava in all flours. 22 formulations of cupcakes were elaborated using the flours (100% substitutions), flour mixture (substitution 50:50 of each flour) and wheat as control, also the egg content (standard content to egg and lower content to egg), to analyze their sensory characteristics and consumer preferences. The study data was carried out with two independents groups of people, a trained panel that has conducted the descriptive analysis and a consumer group that has made the study of acceptance. An analysis of variance was applied to data, test Fisher LSD and external preference mapping, an analysis of ''cluster '' for proof of acceptance, with witch were identified the three consumer groups, composed by 19, 51, 35 people. All three groups have preferred the control samples with wheat in groups 2 and 3 cupcakes with rice-cassava with content standard and less content of egg, and cassava with less egg, have showed without significant differences in preference (p [es

  18. Elaboration of metallic and composite fillings by plasma transferred arc. Process analysis and tribological study

    1987-01-01

    The experimental part of this research thesis addresses the parametric study of two surface filling processes (by plasma transferred arc, and by plasma arc projection followed by a coating remelting by electron beam), the elaboration by plasma transferred arc and the metallurgical characterization of fillings of nickel base alloys and composite materials made of tungsten carbides dispersed in a nickel matrix, and the characterization of fretting wear of the so-elaborated fillings in aqueous environment. The results show that the plasma transferred arc filling technique allows coating quality and microstructure to be controlled by adjusting the mass energy of the transferred arc. Besides, this technique results in a very good control of nickel alloy coatings. The various studied composites show that it is better to use a matrix with very few alloying elements or pre-coated carbides in order to avoid any cracking phenomenon. The content of dispersed carbides must not be greater than 60 per cent in weight. The best wear behaviour is obtained with polyhedral tungsten carbides dispersed within a low alloyed nickel matrix [fr

  1. Ethical issues in health-care inquiry: a discussion paper.

    Science.gov (United States)

    Ignacio, Jeanette J; Taylor, Beverley Joan

    2013-02-01

    This paper is a discussion of the possible ethical dilemmas that may arise in both qualitative and quantitative research despite stringent methodological protocols. Three categories of ethical issues will be elaborated on, namely, researcher-participant relations, informed consent and confidentiality and privacy. These are of note because ethical dilemmas most often arise in these areas. Both qualitative and quantitative research types may thus present with problems associated with any, or a combination, of these categories. Methodological rigour will also be discussed as a vital component of any research study. Critics of the qualitative approach have often suggested that the innate lack of methodological rigour has resulted in the preponderance of ethical issues in qualitative studies. Qualitative studies, similar to quantitative studies, have mechanisms that guarantee rigour, quality and trustworthiness. These checks are at par with those of quantitative research but based on different criteria. Both types of research, then, can be considered equal in terms of methodological rigour, regardless of the nature. As no research approach can be perfectly free from threats of ethical issues, it is the researcher's responsibility to address these in ways that will be less harmful to the participants, bearing in mind ethical problems can arise at any time during the research endeavour. © 2013 Wiley Publishing Asia Pty Ltd.

  2. Climate Change: reflections to support this discussion in Physics classes

    Full Text Available The subject of Climate Changes is an everyday issue in our lives, due to media network information. Many questions about this theme are presented and discussed in a large sort of massive communication media. Despite this situation, we have to say that many of these issues are open subjects for the international scientific community, without a common sense about the causes and consequences of climate changes. In this context, Physics offers theoretical concepts and a way of modeling nature to produce some knowledge about this subject mainly because it is a basic science. From this point of view, the issue of climate changes can be considered a specially useful subject to illustrate these physical concepts by Physics teachers, to motivate students or to elaborate new educational proposals. In order to provide some tools to teach this subject in High School Physics classes, this paper offers two perspectives: to point out some physical considerations about this theme and to discuss a few uncertainties and controversies related to climate changes. In a specific way we will present some considerations about the energy balance in the Sun-Earth system, the greenhouse effect and the concept of the mean temperature of the Earth.

    Directory of Open Access Journals (Sweden)

    Belyakov A. V.

    2012-04-01

    Full Text Available The proposed model is based on Wheeler’s geometrodynamics of fluctuating topology and its further elaboration based on new macro-analogies. Micro-particles are conside- red here as particular oscillating deformations or turbulent structures in non-unitaty coherent two-dimensional surfaces. The model uses analogies of the macro-world, includes into consideration gravitational forces and surmises the existence of closed structures, based on the equilibrium of magnetic and gravitational forces, thereby sup- plementing the Standard Model. This model has perfect inner logic. The following phenomena and notions are thus explained or interpreted: the existence of three genera- tions of elementary particles, quark-confinement,“Zitterbewegung”, and supersymme- try. Masses of leptons and quarks are expressed through fundamental constants and calculated in the first approximation. The other parameters — such as the ratio among masses of the proton, neutron and electron, size of the proton, its magnetic moment, the gravitational constant, the semi-decay time of the neutron, the boundary energy of the beta-decay — are determined with enough precision.

    2016-01-01

    After having recalled the relevant regulatory texts and guides, this guide aims at detailing conditions of elaboration and of modification of the waste zoning plan which is defined in one of these texts, and applies requirements and recommendations of others of them. It first recalls the general doctrine of waste management in basic nuclear installations. It describes how the waste zoning plan and the reference waste zoning map are elaborated and justified, how the relevancy of this plan and this map are confirmed through radiological controls and based on general operation rules and periodic assessments. It also describes how contamination transfers and material activation are prevented, and discusses waste radiological controls to be performed. The next part addressed waste zoning and ways of management for wastes coming from conventional waste areas, and from areas of possible production of nuclear wastes. Issues of waste zoning downgrading or reclassification are then addressed by distinguishing temporary and definitive modifications (in one way or the other). Some peculiar cases are addressed: delimitation of waste zoning at the level of equipments, conventional processing of some wastes, radioactive waste warehousing, outdoor areas of possible production of nuclear wastes

    We report the synthesis of diacid-terminated PEG-functionalized cubic TiO(2) nanocrystals by a simple one-step solvothermal method, and their further use to form nanostructured surfaces for protein immobilization. The relevance and major interest of the so-obtained nanocrystals are the presence of terminal carboxylic acid groups at their surface, as confirmed by infrared analyses, in addition to the surrounding PEG chains, essential to avoid non specific interactions. These functional chemical groups were used to (i) immobilize the synthesized nanocubes on a cysteamine-modified Au surface, and to (ii) attach proteins via a presumable covalent link. AFM images show that the shapes and the narrow size distribution of the nanocubes, observed by TEM, were preserved after their immobilization on the modified Au surface. Moreover, the efficiency and specificity of antigen recognition were demonstrated using spectroscopic analyses. Our successful approach provides a versatile and facile way to elaborate specific and sensitive nanostructured surfaces for biosensors.

    2000-04-01

    From an Elaboration Likelihood Model perspective, it was hypothesized that postexposure awareness of deceptive packaging claims would have a greater negative effect on scores for purchase intention by consumers lowly involved rather than highly involved with a product (n = 40). Undergraduates who were classified as either highly or lowly (ns = 20 and 20) involved with M&Ms examined either a deceptive or non-deceptive package design for M&Ms candy and were subsequently informed of the deception employed in the packaging before finally rating their intention to purchase. As anticipated, highly deceived subjects who were low in involvement rated intention to purchase lower than their highly involved peers. Overall, the results attest to the robustness of the model and suggest that the model has implications beyond advertising effects and into packaging effects.

    Business process management (BPM) principles are commonly used to improve processes within an organisation. But they can equally be applied to supporting the design of an Information System (IS). In a collaborative situation involving several partners, this type of BPM approach may be useful to support the design of a Mediation Information System (MIS), which would ensure interoperability between the partners' ISs (which are assumed to be service oriented). To achieve this objective, the first main task is to build a collaborative business process cartography. The aim of this article is to present a method for bringing together collaborative information and elaborating collaborative business processes from the information gathered (by using a collaborative situation framework, an organisational model, an informational model, a functional model and a metamodel and by using model transformation rules).

    With a great potential for the development and civilian use of the uranium industrial complex in Kazakhstan, there are several existing obstacles in the form of public opinion which still possesses a strong ''radiation phobia'' as a result of past military activity in the Republic. It is not enough to have talks on the radio or articles in newspapers from famous authoritative individuals to overcome this radiation phobia. Systematic education of the public is necessary in order to cultivate a new generation of ecological specialists and business specialists. Therefore, it is necessary to create a plan to carry out this daunting task. In this paper, the creation of such a plan is elaborated. (author)

    Full Text Available One of the unique challenges of reading Les damnés de la terre (The Wretched of the Earth today is that while it is an irredeemably revolutionary text, we live in a counter-revolutionary moment or in a global context that has tried very hard to discredit even the possibility of revolution. Fanon’s text does not only narrate the effective undertaking of an anti-colonial struggle—of what is required for people to identify the actual causes of their alienation and unfreedom and together to will their elimination—it also outlines the various, often dialectical challenges of restructuring a society from the bottom up. Guiding and evident in the latter is the flourishing of what Fanon suggestively called national consciousness. Elaborating its meaning and ongoing usefulness is the focus of this essay.

    The incorporation of nano-sized sepiolite clays into thermoplastic starch/poly(butylene adipate-co-terephthalate) (TPS/PBAT) blends has been investigated with the goal of improving the matrix properties. TPS/PBAT nano-biocomposites were elaborated with two different proportions of the polymeric phases. The influence of the sepiolite nanoclays on the mechanical, thermal and structural properties of the corresponding blends was evaluated. SEM images confirmed the good dispersion of the sepiolite clay, with a low occurrence of small aggregates in the polymeric matrix. Wide-angle X-ray diffraction showed no significant alteration of the crystalline structures of PBAT and starch induced by the sepiolite clay. The addition of sepiolite slightly affected the thermal degradation of the nano-biocomposites; however, the mechanical tests revealed an increase in some mechanical properties, demonstrating that sepiolite is a promising nanofiller for TPS-based materials.

    Shu, Wei; Lorente, Adriana; Gómez-Bengoa, Enrique; Nevado, Cristina

    2017-01-01

    The quest for selective C-H functionalization reactions, able to provide new strategic opportunities for the rapid assembly of molecular complexity, represents a major focus of the chemical community. Examples of non-directed, remote Csp3-H activation to forge complex carbon frameworks remain scarce due to the kinetic stability and thus intrinsic challenge associated to the chemo-, regio- and stereoselective functionalization of aliphatic C-H bonds. Here we describe a radical-mediated, directing-group-free regioselective 1,5-hydrogen transfer of unactivated Csp3-H bonds followed by a second Csp2-H functionalization to produce, with exquisite stereoselectivity, a variety of elaborated fused ketones. This study demonstrates that aliphatic acids can be strategically harnessed as 1,2-diradical synthons and that secondary aliphatic C-H bonds can be engaged in stereoselective C-C bond-forming reactions, highlighting the potential of this protocol for target-oriented natural product and pharmaceutical synthesis.

    Modern standards and definitions of deliverables for software development are provided by various standards like PSS-05, CMMI, ECSS, Volere, Rational Unified process or SPICE (ISO 15504). Modern document templates and the corresponding documents are based on atomic shells that cross-link, and can be subsequently assembled into a set of complete documents; views of the information in the shells. This makes the information easy to maintain, and enables selective views of the documentation. The authors will present a catalogue of document templates that has been developed in the context of the CMS CAFE forum, as well as their cross-linkage, using UML as the modelling language. The templates allow for documenting the elaboration and architectural design phases of software development. They can be used as the basis for establishing and documenting architecture, while establishing trace-ability to use-cases, requirements, constraints, and important technological choices in a maintainable manner

    Full Text Available Staphylococcus aureus TF2758 is a clinical isolate from an atheroma and a super-biofilm-elaborating/polysaccharide intercellular adhesin (PIA/poly-N-acetylglucosamine (PNAG-overproducing strain (L. Shrestha et al., Microbiol Immunol 60:148–159, 2016, https://doi.org/10.1111/1348-0421.12359. A microarray analysis and DNA genome sequencing were performed to identify the mechanism underlying biofilm overproduction by TF2758. We found high transcriptional expression levels of a 7-gene cluster (satf2580 to satf2586 and the ica operon in TF2758. Within the 7-gene cluster, a putative transcriptional regulator gene designated rob had a nonsense mutation that caused the truncation of the protein. The complementation of TF2758 with rob from FK300, an rsbU-repaired derivative of S. aureus strain NCTC8325-4, significantly decreased biofilm elaboration, suggesting a role for rob in this process. The deletion of rob in non-biofilm-producing FK300 significantly increased biofilm elaboration and PIA/PNAG production. In the search for a gene(s in the 7-gene cluster for biofilm elaboration controlled by rob, we identified open reading frame (ORF SAOUHSC_2898 (satf2584. Our results suggest that ORF SAOUHSC_2898 (satf2584 and icaADBC are required for enhanced biofilm elaboration and PIA/PNAG production in the rob deletion mutant. Rob bound to a palindromic sequence within its own promoter region. Furthermore, Rob recognized the TATTT motif within the icaR-icaA intergenic region and bound to a 25-bp DNA stretch containing this motif, which is a critically important short sequence regulating biofilm elaboration in S. aureus. Our results strongly suggest that Rob is a long-sought repressor that recognizes and binds to the TATTT motif and is an important regulator of biofilm elaboration through its control of SAOUHSC_2898 (SATF2584 and Ica protein expression in S. aureus.

    Common beans have been associated with anti-diabetic effects, due to its high content of bioactive compounds. Nevertheless, its consumption has decreased worldwide. Therefore, there is an increasing interest in the development of novel functional foods elaborated with common beans. The aim of this study was to evaluate the anti-diabetic effect of oat-bean flour cookies, and to analyze its bioactive composition, using commercial oat-wheat cookies for comparative purposes. Oat-bean cookies (1.2 g kg -1 ) slightly decreased serum glucose levels (∼1.1-fold) and increased insulin levels (∼1.2-fold) in diabetic rats, reducing the hyperglycemic peak in healthy rats (∼1.1-fold). Oat-bean cookies (0.8 and 1.2 g kg -1 ) exerted a greater hypolipidemic effect than commercial oat-wheat cookies (1.2 g kg -1 ), as observed in decreased serum triglycerides and low-density lipoprotein cholesterol. Furthermore, the supplementation with 1.2 g kg -1 oat-bean cookies decreased atherogenic index and serum C-reactive protein levels, suggesting their cardioprotective potential. The beneficial effect of oat-bean cookies was associated with their high content of dietary fiber and galacto oligosaccharides, as well as chlorogenic acid, rutin, protocatechuic acid, β-sitosterol and soyasaponins. These results suggest that common beans can be used as functional ingredients for the elaboration of cookies with anti-diabetic effects. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Methods: A total of 40 T-loop springs (TLS hand-bent from 0.017 x 0.025-in b-Ti were randomly divided into four groups according to wire brand: TMATM(G1, BETA FLEXYTM (G2, BETA III WIRETM (G3 and BETA CNATM (G4. Forces and moments were recorded by a moment transducer, coupled to a digital extensometer indicator adapted to a testing machine, every 0.5 mm of deactivation from 5 mm of the initial activation. The moment-to-force (MF ratio, the overlapping of the vertical extensions of the TLSs and the load-deflection (LD ratio were also calculated. To complement the results, the Young's module (YM of each wire was determined by the slope of the load-deflection graph of a tensile test. The surface chemical composition was also evaluated by an energy dispersive X-ray fluorescence spectrometer. Results: All groups, except for G2, produced similar force levels initially. G3 produced the highest LD rates and G1 and G4 had similar amounts of overlap of the vertical extensions of the TLSs in "neutral position". G1 and G3 delivered the highest levels of moments, and G2 and G3 produced the highest MF ratios. b-Ti wires from G3 produced the highest YM and all groups showed similar composition, except for G2. Conclusion: The four beta-titanium wires analyzed produced different force systems when used in a more elaborate design due to the fact that each wire responds differently to bends.

    Full Text Available One  of  the  main  issues  often  discussed  among  academics  is  how  to  encourage  active participation by students during classroom discussions. This applies particularly to students at the tertiary level who are expected to possess creative and critical thinking skills. Hence, this paper reports on a study that examined how these skills were demonstrated by a group of university students  who  employed  intertextual  links  during  a  follow-up  reading  activity involving  small-group  text  discussions.  Thirty  undergraduates  who  were  in  their  fifth semester of a TESL degree programme were prescribed reading texts consisting of two chapters taken  from  a  book.  Findings  reveal  that  intertextual  links  made  during  text discussions created successfully a “collaborative environment” where beliefs and values were shared judicially among participants. Pedagogical implications for ESL classroom practice include  heightening  the  awareness  amongst  academics  and  students  of  the  role  of intertextuality in order to promote students’ use of their critical and creative thinking skills in a supportive classroom environment.

  3. Accelerating Cleanup: Focus on 2006. Discussion draft

    International Nuclear Information System (INIS)

    1997-01-01

    This executive summary addresses the activities associated with the National Transuranic (TRU) Program managed by the Carlsbad Area Office (CAO). The CAO programmatically reports to the Assistant Secretary for Environmental Management and receives administrative support through the Albuquerque Operations Office. The mission of the Carlsbad Area Office (CAO) is to protect human health and the environment by opening and operating the Waste Isolation Pilot Plant for site disposal of TRU waste and by establishing an effective system for management of TRU waste from generation to disposal. It includes personnel assigned to the CAO, the Waste Isolation Pilot Plant (WIPP) site operations, and other activities associated with the National TRU Program. The CAO develops and directs implementation of the program, while the DOE Headquarters establishes policy and guidelines. The CAO assesses compliance with the program guidance, as well as the commonality of activities and assumptions among all the sites. Since the development of the February 28, 1997, database used to develop this Discussion Draft, the opening of the WIPP facility for receipt of Contact Handled waste has been delayed from November 1997 to May 1998. This slippage is significant enough to require a change in the milestones and volumes included in the documents to be reviewed by our stakeholders. Changes have been incorporated into this Discussion Draft and its supporting Project Baseline Summaries (PBSs)

  4. Electric and mechanical basic parameters to elaborate a process for a technical verification of safety related design modifications

    2010-01-01

    This paper presents a systematic process to check a design in order to achieve all the requirements that regulations demand. Nuclear engineers must verify that a design is done according to the safety requirements, and this paper presents how we have elaborated a process to improve the technical project verification. For a faster, better and easier verification process, here we summarize how to select the electric and mechanical basic parameters, which ensure the correct project verification of safety related design modifications. This process considers different aspects, which guarantee that the design preserves the availability, reliability and functional capability of the Structures, Systems and Components needed to operate the Nuclear Power Station with security. Electric and mechanical reference parameters are identified and discussed as well as others related ones, which are critical to safety. The implementation procedure to develop tasks performed in any company that has a quality plan is a requirement. On the engineering business, it is important not to use the personal criteria to do a technical analysis of a project; although, many times it is the checker's criteria and knowledge responsibility to ensure the correct development of a design modification. Then, the checker capabilities are the basis of the modification verification. This kind of procedure's development is not easy, because in an engineering project with important technical contents, there are multiple scenarios, but lots of them have a common basis. If we can identify the technical common basis of these projects, we will make good project verification but there are many difficulties we can encounter along this process. (authors)

  5. Diffusion-bonded 16MND5-Inconel 690-316LN junction: elaboration and process residual stresses modeling

    International Nuclear Information System (INIS)

    Martinez, Michael

    1999-01-01

    The objective of this research thesis is, on the one hand, to elaborate and to characterise a bonded junction of 16MND5 and 316LN steels, and, on the other hand, to develop a simulation tool for the prediction of microstructures after bonding, as well as residual stresses related to this process. The author first reports the study of the use of diffusion bonding by hot isostatic pressing (HIP diffusion bonding) for the bonding of 16MND5 (steel used in French PWR vessel) and 316LN (austenitic stainless steel used in piping), in order to obtain junctions adapted to a use within PWRs. In this case, the use of an Inconel insert material appeared to be necessary to avoid stainless steel carburization. Thus, inserts in Inconel 600 and 690 have been tested. The objective has then been to develop a realistic calculation of residual stresses in this assembly. These stresses are stimulated by quenching. The author notably studied the simulation of temperature dependent phase transformations, and stress induced phase transformations. An existing model is validated and applied to HIP and quenching cycles. The last part reports the calculation of residual stresses by simulation of the mechanical response of the three-component material cooled from 900 C to room temperature and thus submitted to a loading of thermal origin (dilatation) and metallurgical origin (phase transformations in the 16MND5). The effect of carbon diffusion on mechanical properties has also been taken into account. The author discusses problems faced by existing models, and explains the choice of conventional macro-mechanical models. The three materials are supposed to have a plastic-viscoplastic behaviour with isotropic and kinematic strain hardening, and this behaviour is identified between 20 and 900 C [fr

    The production furnace is an induction heated vacuum furnace having a capacity at the moment of 250 kg. Previously the crucible was heated by the inductor, the mould being outside the inductor. The tubes thus produced contained cavities, the alloy structure was fine; this was cold-mould casting, At the moment the top of the moulds are pre-heated, this is the so called hot-mould casting. This method has the advantage of eliminating the cavities but leads to a less fine microstructure. The alloy used for the 18 x 40 mm and 23 x 43 mm tubes is U-Mo (1.1 per cent). Since the moulds are now heated at the top, the solidification of the metal is very slow in this zone leading to a pronounced {gamma} grain, whereas towards the base the faster cooling leads to a smaller {gamma} grain. The {gamma} structure depends essentially on the solidification rate and on the time spent in this zone. In order to obtain a fine and homogeneous grain along the whole length of the tube, a controlled cooling treatment is effected. It consists in heating the uranium tubes in the {gamma} place and then in cooling them at a rate of between 20 and 50 deg C/mm down to 400 deg C. The 77 x 95 mm and 54 x 70 mm annular elements are at the moment being produced for research purposes. Their preparation is similar to that of 18 x 40 mm and 23 x 43 mm elements. The 77 x 95 mm tubes are at the moment made from U-Cr alloy (0.1 per cent); because of their size, their preparation is carried out in 600 mm diameter furnaces.

    Martinez, Jean-Philippe

    2017-11-01

    The Hartree-Fock method, one of the first applications of the new quantum mechanics in the frame of the many-body problem, had been elaborated by Rayner Douglas Hartree in 1928 and Vladimir Fock in 1930. Promptly, the challenge of tedious computations was being discussed and it is well known that the application of the method benefited greatly from the development of computers from the mid-to-late 1950s. However, the years from 1930 to 1950 were by no means years of stagnation, as the method was the object of several considerations related to its mathematical formulation, possible extension, and conceptual understanding. Thus, with a focus on the respective attitudes of Hartree and Fock, in particular with respect to the concept of quantum exchange, the present work puts forward some mathematical and conceptual clarifications, which played an important role for a better understanding of the many-body problem in quantum mechanics.

  10. Teaching and learning grade 7 science concepts by elaborate analogies: Mainstream and East and South Asian ESL students' experiences

    Science.gov (United States)

    Kim, Judy Joo-Hyun

    This study explored the effectiveness of an instructional tool, elaborate analogy, in teaching the particle theory to both Grade 7 mainstream and East or South Asian ESL students. Ten Grade 7 science classes from five different schools in a large school district in the Greater Toronto area participated. Each of the ten classes were designated as either Group X or Y. Using a quasi-experimental counterbalanced design, Group X students were taught one science unit using the elaborate analogies, while Group Y students were taught by their teachers' usual methods of teaching. The instructional methods used for Group X and Y were interchanged for the subsequent science unit. Quantitative data were collected from 95 students (50 mainstream and 45 ESL) by means of a posttest and a follow-up test for each of the units. When the differences between mainstream and East or South Asian ESL students were analyzed, the results indicate that both groups scored higher on the posttests when they were instructed with elaborate analogies, and that the difference between the two groups was not significant. That is, the ESL students, as well as the mainstream students, benefited academically when they were instructed with the elaborate analogies. The students obtained higher inferential scores on the posttest when their teacher connected the features of less familiar and more abstract scientific concepts to the features of the familiar and easy-to-visualize concept of school dances. However, after two months, the students were unable to recall inferential content knowledge. This is perhaps due to the lack of opportunity for the students to represent and test their initial mental models. Rather than merely employing elaborate analogies, perhaps, science teachers can supplement the use of elaborate analogies with explicit guidance in helping students to represent and test the coherence of their mental models.

  11. Methodology for Elaborating Regional Susceptibility Maps of Slope Instability: the State of Guerrero (mexico) Case Study

    Numerous cases of different types of slope instability occur every year in the mountain areas of México. Sometimes these instabilities severely affect the exposed communities, roads and infrastructure, causing deaths and serious material damage, mainly in the states of Puebla, Veracruz, Oaxaca, Guerrero and Chiapas, at the central and south sectors of the country. The occurrence of the slope instability is the result of the combination of climatic, geologic, hydrologic, geomorphologic and anthropogenic factors. The National Center for Disaster Prevention (CENAPRED) is developing several projects in order to offer civil protection authorities of the Mexican states some methodologies to address the hazard assessment for different natural phenomena in a regional level. In this framework, during the past two years, a methodology was prepared to construct susceptibility maps for slope instability at regional (≤ 1:100 000) and national (≤ 1:1 000 000) levels. This research was addressed in accordance to the criteria established by the International Association of Engineering Geology, which is the highest international authority in this topic. The state of Guerrero has been taken as a pilot scheme to elaborate the susceptibility map for slope instability at a regional level. The major constraints considered in the methodology to calculate susceptibility are: a) the slope of the surface, b) the geology and c) the land use, which were integrated using a Geographic Information System (GIS). The arithmetic sum and weighting factors to obtain the final susceptibility map were based on the average values calculated in the individual study of several cases of slope instability occurred in the state in the past decade. For each case, the evaluation format proposed by CENAPRED in 2006 in the "Guía Básica para la elaboración de Atlas Estatales y Municipales de Peligros y Riesgos" to evaluate instabilities in a local level, was applied. The resulting susceptibility map shows

    The Laboratory of Radioactive patterns account with a 4 {pi}{beta}-{gamma} coincidence system of recent acquisition with which absolute measures of radioactive activity with uncertainties of the order of 0.1% can be made. Since the coincidence method for the activity measure consists on detecting to the particle and the photon corresponding to oneself nuclear disintegration, it is necessary to elaborate special radioactive sources on thin supports, in order to allowing the maximum possible fluence of {beta} particles ({approx} 100%). This work a technique for the elaboration of these sources and for the measure of the thickness of the walls of the support is presented. (Author)

  14. Some remarks about the 'controversial discussions'.

    Hayman, A

    1994-04-01

    In 1943-44, the British Psycho-Analytical Society held the 'Controversial Discussions' in an attempt to resolve various disagreements then current in the theory, practice and teaching of psychoanalysis. This paper selects and assesses in some detail some of the arguments that emerged around the concepts of 'unconscious phantasy' and 'unconscious conflict'. Inter alia, they included arguments about assumed early events, about ways of interpreting and assessing evidence, about modes and different levels of conceptualisation, about interpretations of Freud and about changes in psychoanalyic theory. Attempts to achieve mutual understanding existed side by side with total and sometimes rancorous disagreement. Attention is given to sometimes irresolvable communicative and conceptual difficulties that arose and still arise, from differences in meaning that different psychoanalytic thinkers assigned and still assign to each of the two conceptual terms, 'unconscious phantasy' and 'unconscious conflict'.

  15. Transgenerational epigenetic inheritance: an open discussion.

    2015-08-01

    Much controversy surrounds the idea of transgenerational epigenetics. Recent papers argue that epigenetic marks acquired through experience are passed to offspring, but as in much of the field of epigenetics, there is lack of precision in the definitions and perhaps too much eagerness to translate animal research to humans. Here, we review operational definitions of transgenerational inheritance and the processes of epigenetic programing during early development. Subsequently, based on this background, we critically examine some recent findings of studies investigating transgenerational inheritance. Finally, we discuss possible mechanisms that may explain transgenerational inheritance, including transmission of an epigenetic blueprint, which may predispose offspring to specific epigenetic patterning. Taken together, we conclude that presently, the evidence suggesting that acquired epigenetic marks are passed to the subsequent generation remains limited.

These discussions were reviewed to assess their value in education and aiding patient management. Materials and Methods: All messages and discussions between August 2007 and July 2008 were examined retrospectively. Data were collected regarding topics, replies, and use of clinical images. Results: A total of 2217 messages were exchanged within 330 separate discussions (mean = 6.7 messages per discussion, range = 0-45. A total of 164 discussions contained photographs (50%. Mean number of photographs per discussion was five (range = 0-34. Discussions included requests for advice on complex cases (40%, interesting cases and their management/outcome (25% and courses/conferences (30%. Topics discussed include training/courses (26.7%, cleft (15.4%, aesthetics (13.1%, trauma (12.5%, head and neck (8.4%, cutaneous (6.4%, perineal/genital reconstruction (6.1%, and scar management (4.7%. Discussion: Forums like this facilitate discussion between individuals in remote locations. They provide easy access to the expertise of a large cohort of highly experienced surgeons. Most discussions were clinical, involving challenging situations. The discussions are open and nonjudgmental, hence encouraging contribution and healthy debate. We encourage its use as an educational tool and a platform for discussion.

    A specific methodology must be applied for the elaboration and implementation of a Radioactive Waste Management Program RWMP. After the implementation of the RWMP, periodic reevaluations must be foreseen for both updating and assuring compliance with applicable legal requirements. One of the main steps of the elaboration or reevaluation of the RWMP of a given facility is the diagnosis of the issues related to wastes generation where they are generated (diagnosis at source). Some of the information gathered during the diagnosis are: the identification of the generation points and respective operations of waste generation; the characteristics and quantification of the radioactive wastes; the waste collection and local storage status; the techniques used for preventing and minimizing the generation of radioactive wastes, including practices of waste segregation; and the procedures for control of the radioactive wastes generated at each generation point. In this diagnosis is also enclosed the identification of the staff, at each radioactive waste generation point, who is directly or indirectly in charge of the waste management activities. The objective of this paper is to describe the adopted methodology and the computational implementation of a checklist to verify the current situation of the radioactive waste management at the source.

    N-of-1 trials are a useful tool for clinicians who want to determine the effectiveness of a treatment in a particular individual. The reporting of N-of-1 trials has been variable and incomplete, hindering their usefulness in clinical decision making and by future researchers. This document presents the CONSORT (Consolidated Standards of Reporting Trials) extension for N-of-1 trials (CENT 2015). CENT 2015 extends the CONSORT 2010 guidance to facilitate the preparation and appraisal of reports of an individual N-of-1 trial or a series of prospectively planned, multiple, crossover N-of-1 trials. CENT 2015 elaborates on 14 items of the CONSORT 2010 checklist, totalling 25 checklist items (44 sub-items), and recommends diagrams to help authors document the progress of one participant through a trial or more than one participant through a trial or series of trials, as applicable. Examples of good reporting and evidence based rationale for CENT 2015 checklist items are provided. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

    Adequate reporting of randomized, controlled trials (RCTs) is necessary to allow accurate critical appraisal of the validity and applicability of the results. The CONSORT (Consolidated Standards of Reporting Trials) Statement, a 22-item checklist and flow diagram, is intended to address this problem by improving the reporting of RCTs. However, some specific issues that apply to trials of nonpharmacologic treatments (for example, surgery, technical interventions, devices, rehabilitation, psychotherapy, and behavioral intervention) are not specifically addressed in the CONSORT Statement. Furthermore, considerable evidence suggests that the reporting of nonpharmacologic trials still needs improvement. Therefore, the CONSORT group developed an extension of the CONSORT Statement for trials assessing nonpharmacologic treatments. A consensus meeting of 33 experts was organized in Paris, France, in February 2006, to develop an extension of the CONSORT Statement for trials of nonpharmacologic treatments. The participants extended 11 items from the CONSORT Statement, added 1 item, and developed a modified flow diagram. To allow adequate understanding and implementation of the CONSORT extension, the CONSORT group developed this elaboration and explanation document from a review of the literature to provide examples of adequate reporting. This extension, in conjunction with the main CONSORT Statement and other CONSORT extensions, should help to improve the reporting of RCTs performed in this field.

    Barium titanate (BaTiO{sub 3}) thick films were prepared from commercial powder to develop and optimize the film elaboration. Then, BaTiO{sub 3} was doped by strontium and iron to increase the conductivity by a double substitution on site A and B of the perovskite structure in view to develop semiconductor gas sensors. Film inks were prepared by mixing BT and BSTF powder with an organic vehicle, using a ratio of 50:50; 60:40, respectively and deposited on alumina substrates. The BT and BSTF films were sintered at 1100°C for 2h. The structural and physical properties of the films have been studied by using X-ray diffraction (XRD) and scanning electron microscope (SEM). The dielectric measurements showed a huge increase in the a.c. conductivity for the BSTF films, by a factor of 10000 at low frequency, when the temperature ranges from 25°C to 500°C.

    A previous study on the problems of scaling and extrapolation of experimental results indicated the necessity to overcome some uncertainty in the achievable code accuracy when applied to full size reactor systems. The empirical approach in simulating interfacial relationships within systems behaviour codes in combination with the liberty of nodalisation requires a careful assessment of the overall validity of the code verification concept. Several new test facilities are presently under construction to study fluid-dynamic effects of interest for the behaviour of PWRs under small break LOCA conditions in a larger dimension and with somewhat modified scaling considerations. The test results expected from these new facilities may be useful to assess the overall validity of the analytical simulation concept of the applied computer codes. Test facilities of interest within the European Community are the - LOBI Test Facility (vol. scaling 1/700) at JRC-Ispra - SPES Test Facility (vol. scaling 1/425) in Italy - BETHSY Facility (vol scaling 1/100) in France and outside Europe the - ROSA IV Facility (vol. scaling 1/50) in Japan. Main objective of the study was the elaboration of a guideline for the particular requirements of meaningful counterpart testing with the final aim to qualify the overall validity of code simulation concepts and the expected predictive accuracy of code applications for full size prototype PWRs

    All safety measures taken during the design, the construction and the operation of a nuclear power plant decrease to an extremely low level the probability of an accident with unacceptable consequences for the public. Nevertheless, for the case such an accident should be initiated, emergency plans have been elaborated: the on-site emergency plan to protect the plant personnel, terminate the accident and mitigate the consequences; the short-term and longer-term off-side emergency plans to protect the public and organise the return to acceptable living conditions. The appropriateness and preparedness of such plans have to be checked regularly by means of drills, which may be restricted to technical aspects concerning the nuclear units, or involve all actors, i.e. the utility, all the branches of the administration concerned and a media simulation. Some aspects of the choice of goals and preparation of drills are presented and illustrated by the national EPAULE exercice in 1987. Technically speaking, the drills have proved the validity of the current organization and evidenced its operability: uncertainties remain as regards the actual vs expected behavior of the population, due to emotional aspects linked to the lack of direct perception of the degree of danger and to the information received in an actual nuclear emergency

    In the actual context of population ageing and extension of working age, programs for health promotion at the workplace are a key and necessary tool to promote an active and healthy ageing. This work presents the methodological process followed to elaborate a checklist tool, within the framework of the European project Progress, that contributes to orientate planning, implementation and evaluation of good practices in this field, to be applicable to a variety of programs, countries and workplaces. A Delphi technique has been applied in three rounds in which experts in the area from five European countries participated. A questionnaire created from a list of criteria and indicators was adapted throughout the rounds, with the use of webmail, to the evaluation of interventions in the field of interest. Through processes of assessment and consensus, criteria and indicators most relevant were prioritized. From the nine starting criteria and after the implementation of the technique, four key criteria were prioritized: relevance: 62, adequacy to objective: 57, innovation: 50 and guarantee of quality: 41. Using this group of criteria and indicators, a checklist was designed containing the key information that should be collected for planning, implementation and evaluation of good practices in interventions in this field. The checklist tool helps to systematize the global methodology for the implementation of interventions which could be very useful for persons responsible of programmes to promote active and healthy ageing in the workplace.

    Full Text Available The paper presents the main achievements of the author on the development of blood contacting materials. The main objective of the work is to elaborate materials dedicated for the heart support systems. Appropriately designed biomaterial surfaces enable fully controlled cellular differentiation, proliferation, and even restoration of the tissue structure on solids. The paper presents two approaches to modify the surface, which can control the life processes of tissue. The first solution considers the topography in the form of cell niches. The main objective of the study is a modified surface of thin films deposited on the polymer substrate constituting the microenvironment for the cells caused by residual stress and optimized stiffness of the surface using the plasma methods. The research hypothesis was the plasma surface modification method generating a controlled contribution of residual stress in the coating affect the surface topography in the form of nano- wrinkles similar to the niches in the tissue environment. Topography and stiffness of the surface coating allows the targeted cellular differentiation. The properly formed surface topography effectively inhibits blood clotting processes. The second solution considers implementation of self-organizing feature of extracellular matrix like coatings and selective cell mobilization. The multiscale analysis and phenomenologic description were performed to experimental research. For this purpose, the deposition method was based on electrostatic interactions in polyelectrolytes. This type of cell-polymer structure imitate the native structures.

  7. Elaborate horns in a giant rhinoceros beetle incur negligible aerodynamic costs.

    Sexually selected ornaments and weapons are among nature's most extravagant morphologies. Both ornaments and weapons improve a male's reproductive success; yet, unlike ornaments that need only attract females, weapons must be robust and functional structures because they are frequently tested during male-male combat. Consequently, weapons are expected to be particularly costly to bear. Here, we tested the aerodynamic costs of horns in the giant rhinoceros beetle, Trypoxylus dichotomus. We predicted that the long, forked head horn would have three main effects on flight performance: increased body mass, an anterior shift in the centre of mass and increased body drag. We found that the horns were surprisingly lightweight, and therefore had a trivial effect on the male beetles' total mass and mass distribution. Furthermore, because beetles typically fly at slow speeds and high body angles, horns had little effect on total body drag. Together, the weight and the drag of horns increased the overall force required to fly by less than 3 per cent, even in the largest males. Because low-cost structures are expected to be highly evolutionarily labile, the fact that horns incur very minor flight costs may have permitted both the elaboration and diversification of rhinoceros beetle horns.

    The theory of middle managers' role in implementing healthcare innovations hypothesized that middle managers influence implementation effectiveness by fulfilling the following four roles: diffusing information, synthesizing information, mediating between strategy and day-to-day activities, and selling innovation implementation. The theory also suggested several activities in which middle managers might engage to fulfill the four roles. The extent to which the theory aligns with middle managers' experience in practice is unclear. We surveyed middle managers (n = 63) who attended a nursing innovation summit to (1) assess alignment between the theory and middle managers' experience in practice and (2) elaborate on the theory with examples from middle managers' experience overseeing innovation implementation in practice. Middle managers rated all of the theory's hypothesized four roles as "extremely important" but ranked diffusing and synthesizing information as the most important and selling innovation implementation as the least important. They reported engaging in several activities that were consistent with the theory's hypothesized roles and activities such as diffusing information via meetings and training. They also reported engaging in activities not described in the theory such as appraising employee performance. Middle managers' experience aligned well with the theory and expanded definitions of the roles and activities that it hypothesized. Future studies should assess the relationship between hypothesized roles and the effectiveness with which innovations are implemented in practice. If evidence supports the theory, the theory should be leveraged to promote the fulfillment of hypothesized roles among middle managers, doing so may promote innovation implementation.

    Full Text Available This paper investigates the mineralogical evolution of sulfoaluminate clinker elaborated from moroccan prime materials limestone, shale and phosphogypsum as a byproduct from phosphoric acid factories. The advantage of the production of this type of clinker is related to the low clinkerisation temperature which is known around 1250°C, and to less consumption quantity of limestone thus enabling less CO2 emissions during the decarbonation process compared to that of Portland cement. In this study we determine the stability conditions of belite sulfoaluminate clinker containing belite (C2S ye’elimite (C4A3$ and ternesite (C5S2$. The hydration compounds of this clinker are also investigated. The monitoring of the synthesized and hydrated phases is performed by X-Ray Diffraction and Infrared spectroscopy. The results show the formation of ternesite at 800°C and the stabilization of clinker containing y’elminite, belite and ternesite at temperatures between 1100 and 1250°C.

    Phosphogypsum is a by-product of the phosphatic fertilizer production from the beneficiation of phosphate minerals (apatites). Produced in large quantities throughout the world and stored temporally in stacks, the final destination of this product is nowadays a subject of investigation. Due to the presence of radionuclides ({sup 226}Ra, {sup 232}Th and {sup 40}K, mainly), possible applications for the phosphogypsum must be verified for radiological safety. The goal of this paper was to elaborate a representative water flow conceptual model of a sanitary landfill for the safety assessment of the impact of using phosphogypsum as a cover material. For this, the ground water flow in variably saturated conditions and solute transport model HYDRUS-2D has been used for simulating the impact in the saturated zone of potential radionuclides leaching. The conceptual model was developed by collecting and analyzing the data from environmental license documentation of municipal sanitary landfills located on the State of Minas Gerais, Brazil. In order to fulfill the requirements of HDRUS-2D model in terms of the necessary parameters, the physical characteristics and typical configuration of the landfills, as well as the hydrogeological parameters of soils and aquifers related to the local of placement of the landfills, were taken in account for the formulation of the conceptual model.

    This paper presents an approach for assisting low-literacy readers in accessing Web online information. The "Educational FACILITA" tool is a Web content adaptation tool that provides innovative features and follows more intuitive interaction models regarding accessibility concerns. Especially, we propose an interaction model and a Web application that explore the natural language processing tasks of lexical elaboration and named entity labeling for improving Web accessibility. We report on the results obtained from a pilot study on usability analysis carried out with low-literacy users. The preliminary results show that "Educational FACILITA" improves the comprehension of text elements, although the assistance mechanisms might also confuse users when word sense ambiguity is introduced, by gathering, for a complex word, a list of synonyms with multiple meanings. This fact evokes a future solution in which the correct sense for a complex word in a sentence is identified, solving this pervasive characteristic of natural languages. The pilot study also identified that experienced computer users find the tool to be more useful than novice computer users do.

    Alfa leaves are important renewable raw materials in Tunisia where they are used basically in handcrafts and paper industry. Sumac is also an abundant species in Tunisia known for its high tannin content and is basically used in traditional medicine. To valorize these natural resources, we studied, for the first time, the possibility of making insulating panels based on alfa fibres and sumac tannins based adhesive. Firstly, alfa leaves were treated with an alkali solution as it is one of the standard procedures commonly used in the paper industry to extract cellulosic fibres. Mercerization effects were studied by characterizing fibres thermal properties and fibres surface morphology. Secondly, the sumac tannin based resin was formulated and characterized. Finally, the insulating panel was elaborated and characterized by determining its thermal conductivity. The thermal gravimetric analysis results show improvement in the thermal stability of fibres after alkali treatment. Environmental Scanning Electron Microscopy showed changes on treated alfa surface which could promote the fibre-matrix adhesion. The reactivity of sumac tannins to formaldehyde test (Stiasny number) showed the possible use of sumac tannins in wood adhesive formulation. Thermomechanical analysis and strength analysis of sumac tannin/hexamin based resin highlighted acceptable bonding properties. The thermal conductivity measurement showed an average value equal to 0.110 W/m K.

    Full Text Available Abstract A challenge to the food sector has been the development of new products incorporating co-products from the food processing industry with minimal impact on their pre-determined structures and adding nutritional quality. In order to add value and develop alternatives for the use of co-products generated during the agroindustrial processing, this work aimed to study the stability of gluten-free sweet biscuits developed with soybean okara, rice bran and broken rice. The formulations were elaborated with increasing percentages of these ingredients and compared with the standard (commercial sweet biscuit for ten months. The analyses were: weight, diameters (internal and external, thickness, specific volume, instrumental parameters of color, texture, scanning electron microscopy, water activity, proximal composition and isoflavones. The experimental sweet biscuits had characteristics of color, weight, volume and diameters (internal and external very similar to the commercial, whereas texture, lipids and energy value decreased, and aw, moisture and protein increased during storage. The sweet biscuits showed the same stability when compared to the standard, and the

    Full Text Available The foundry industry contributes to society meeting the demand of metal scrap recycling, but, at the same time, it brings a high risk of environmental impact for its many potentially pollutant wastes. Among these, there are slag and used foundry sand (cold cure molding. Through a survey about the production process of a small cast iron company, the collected data was compiled to determine the organizational setting in terms of generation and segregation of waste. From a complete environmental diagnosis carried out in eight small cast iron foundries, one of them was chosen to be a basis for the elaboration of an industrial solid waste management plan, which is becoming necessary to know and manage the generation of wastes qualitatively and quantitatively. A data assessment about the production process was carried out and compiled to determine the actual organizational scenario. As a result of that, it is possible to create a favorable environment to develop tools for environmental impacts prevention, which will permit the migration for more complex actions on the direction of more efficient process, cleaner production, and internal and external recycling of exceeding materials.

    Complex interventions are widely used in health care, public health, education, criminology, social work, business, and welfare. They have increasingly become the subject of systematic reviews and are challenging to effectively report. The Complex Interventions Methods Workgroup developed an extension to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Complex Interventions (PRISMA-CI). Following the EQUATOR Network guidance for Preferred Reporting Items for Systematic Reviews and Meta-Analysis extensions, this Explanation and Elaboration (EE) document accompanies the PRISMA-CI checklist to promote consistency in reporting of systematic reviews of complex interventions. The EE document explains the meaning and rationale for each unique PRISMA-CI checklist item and provides examples to assist systematic review authors in operationalizing PRISMA-CI guidance. The Complex Interventions Workgroup developed PRISMA-CI as an important start toward increased consistency in reporting of systematic reviews of complex interventions. Because the field is rapidly expanding, the Complex Interventions Methods Workgroup plans to re-evaluate periodically for the need to add increasing specificity and examples as the field matures.

    2016-01-01

    The aim of this article is to further knowledge of the explanatory processes of narrative persuasion in the field of health communication, using data obtained in a research study of entertainment-education based on audiovisual fiction. Participating in the study were 208 young persons between the ages of 14 and 20, randomly distributed to three different groups. Each of the groups was exposed to a different episode of the Colombian television series Revelados, desde todas las posiciones. The results showed that greater identification with the main character of the episode transmitting a prevention message was associated with greater cognitive elaboration, which in turn led to more favorable attitudes toward the topics addressed. However, counterarguing was not observed to play a significant mediating role. The findings of this study allow us to conclude that getting people to think and reflect can help persuade them, which suggests that narrative persuasion models and dual models of rhetorical persuasion can be compatible in certain contexts, such as when messages are designed in such a way that characters make explicit arguments that endorse a prosocial message through dialogues.

    Anticipating effective factors in information system acceptance by using persuasive messages, is one of the main issues less focused on so far. This is one of the first attempts at using the elaboration-likelihood model combined with the perception of emotional, cognitive, self-efficacy, informational and normative influence constructs, in order to investigate the determinants of intention to continue use of the hospital information system in Iran. The present study is a cross-sectional survey conducted in 2014. 600 nursing staff were chosen from clinical sectors of public hospitals using purposive sampling. The questionnaire survey was in two parts: Part one was comprised of demographic data, and part two included 52 questions pertaining to the constructs of the model in the study. To analyze the data, structural equation model using LISREL 8.5 software was applied. The findings suggest that self-efficacy (t= 6.01, β= 0.21), affective response (t= 5.84, β= 0.23), and cognitive response (t= 4.97, β= 0.21) explained 64% of the variance for the intention of continuing to use the hospital information system. Furthermore, the final model was able to explain 0.46 for self-efficacy, 0.44 for normative social influence, 0.52 for affective response, 0.55 for informational social influence, and 0.53 for cognitive response. Designing the necessary mechanisms and effective use of appropriate strategies to improve emotional and cognitive understanding and self-efficacy of the nursing staff is required, in order to increase the intention of continued use of the hospital information system in Iran.

    The elaborated environmental stress hypothesis (EESH) provides a framework that describes how motor skills may indirectly cause internalizing problems through various mediating psychosocial factors. While there is evidence to support this framework, little is known about how the proposed relationships may vary across different stages of development. This study aimed to investigate whether peer problems and perceived self-competence mediated the relationship between motor skills and internalizing problems in pre-primary children, and at 18-month follow up. A community sample of 197 pre-primary school children (M = 5.40 years, SD = 0.30 years; 102 males, 95 females) participated at Time 1, with 107 completing the Time 2 follow-up. Standardized instruments were used to measure motor skills and verbal IQ. Perceived self-competence was measured using a self-report measure. Participant peer problems and internalizing problems were measured using teacher report. Age, gender, and verbal IQ were included as covariates. Mediation analysis using PROCESS showed that the relationship between motor skills and internalizing problems was mediated by peer problems at Time 1. At Time 2, the relationship was mediated by peer problems and perceived physical competence. The current results indicate the EESH may function differently across different periods of development. The transition from pre-primary to Grade 1 represents a time of important cognitive and psychosocial development, which has implications for how the relationship between motor skills and internalizing problems can be understood. These findings highlight potential age-appropriate targets for psychomotor interventions aiming to improve the emotional well-being of young children. © 2017 The British Psychological Society.

    Recent years have seen a considerable growth of interest in the study of life stress and non-suicidal self-injury (NSSI). The current article presents a systematic review of the empirical literature on this association. In addition to providing a comprehensive meta-analysis, the current article includes a qualitative review of the findings for which there were too few cases (i.e., life stress and NSSI was found (pooled OR = 1.81 [95% CI = 1.49–2.21]). After an adjustment was made for publication bias, the estimated effect size was smaller but still significant (pooled OR = 1.33 [95% CI = 1.08–1.63]). This relation was moderated by sample type, NSSI measure type, and length of period covered by the NSSI measure. The empirical literature is characterized by several methodological limitations, particularly the frequent use of cross-sectional analyses involving temporal overlap between assessments of life stress and NSSI, leaving unclear the precise nature of the relation between these two phenomena (e.g., whether life stress may be a cause, concomitant, or consequence of NSSI). Theoretically informed research utilizing multi-wave designs, assessing life stress and NSSI over relatively brief intervals, and featuring interview-based assessments of these constructs holds promise for advancing our understanding of their relation. The current review concludes with a theoretical elaboration of the association between NSSI and life stress, with the aim of providing a conceptual framework to guide future study in this area.

    2017-06-01

    The elaborated-intrusion theory of desire proposes that craving is a two-stage process whereby initial intrusions about a desired target are subsequently elaborated with mental imagery. The present study tested whether the craving reduction strategies of cognitive defusion and guided imagery could differentially target the intrusion and elaboration stages, respectively, and thus differentially impact the craving process. Participants were randomly assigned to a cognitive defusion, a guided imagery or a mind-wandering control condition. Pre- and post-intervention chocolate-related thoughts, intrusiveness of thoughts, vividness of imagery, craving intensity, and chocolate consumption were compared. Experiment 1 recruited a general sample of young women (n = 94), whereas Experiment 2 recruited a sample of chocolate cravers who wanted to reduce their chocolate consumption (n = 97). Across both experiments, cognitive defusion lowered intrusiveness of thoughts, vividness of imagery and craving intensity. Guided imagery reduced chocolate-related thoughts, intrusiveness, vividness and craving intensity for chocolate cravers (Experiment 2), but not for the general sample (Experiment 1). There were no group differences in chocolate consumption in either experiment. Results add to existing evidence supporting the elaborated-intrusion theory of desire in the food domain, and suggest that acceptance- and imagery-based techniques have potential for use in combatting problematic cravings.

    key points can be highlighted: The main question seems to be: 'What are the elements making the funding system safer?' This can be looked at through different aspects: cost estimate; control of the funding and money collection; control of investment of the money; how to cope with uncertainties (including early shutdown and bankruptcy). The stability of the funding system over the time is a key factor for securing the funding (a good counter-example is the UK story). The decommissioning exercise should start before the plant is in operation; i.e. when a plant is constructed. An important aspect is also the information exchange with people having participated to actual D and D projects. Discussions by session: At the plenary discussions the following items were also recorded: the possibility of having an international body managing decommissioning funds; how far the present generation would need to go today to protect future generations from a virtual risk and how far do these ethical considerations need to be covered by the funds; the use of ethical values in the discussion with the public and the stakeholders; the pros and cons of segregated funds; the management and control of funds

  8. Socio-cognitive Elaborations and Reactions to Economic Crisis: Insights from Social Psychology

    Directory of Open Access Journals (Sweden)

    Stamos Papastamou

    2018-01-01

    Full Text Available This special issue dedicated to the social psychological study of the economic crisis in four European Union countries along the Mediterranean includes six empirical papers discussing different aspects of the phenomenon. Four papers are part of a larger project that started in 2011, aiming to compare the social representations of the economic crisis in France, Greece, Italy, and Portugal. Starting from the study of the social representations of the causes of the crisis and the measures to overcome it, various social psychological parameters that interfere are examined. Thus, the political, ideological, and social positioning, and the axiological universe of the participants are considered as important predictors and mediators in the different papers. Additionally, possible political participatory activities in reaction to the crisis are considered. The presentation of the outcome of this research project is completed by a paper analyzing the way the crisis was depicted in the Italian press and a paper looking at the impact of the financial threat to political participation in France. The research presented here reveals the ways social subjects give meaning to a situation of crisis and thus provides social and political insights into social thinking and behavior with important policy implications for individual nations as well as Europe at large. In this paper, we present the general framework of the studies carried out and we introduce the collection of empirical papers of the special issue.

  9. Drinking water protection plan; a discussion document

    2001-01-01

    This draft document outlines the plan of action devised by the Government of British Columbia in an effort to safeguard the purity of the drinking water supply in the province, and invites British Columbians to participate in the elaboration of such a plan. This document concentrates on the assessment of the sources of the water supply (watersheds and aquifers) and on measures to ensure the integrity of the system of water treatment and distribution as the principal components of a comprehensive plan to protect drinking water. The proposed plan involves a multi-barrier approach that will use a combination of measures to ensure that water sources are properly managed and waterworks systems provide safe drinking water. New drinking water planning procedures, more effective local influence and authority, enforceable standards, better access to information and public education programs form the essence of the plan. A series of public meetings are scheduled to provide the public at large with opportunities to comment on the government's plan of action and to offer suggestions for additional measures

Polynomial regression analysis was applied to the data from subgroup EFW-El to elaborate a model for the estimation of fetal weight. The performance of this model was compared to those of previously published formulas. Linear mixed models were used for the elaboration of longitudinal reference intervals of EFW using data from subgroup LRI-El. Data obtained from subgroup LRI-Val were used to validate these intervals. Group EFW consisted of 458 patients (EFW-El: 367; EFW-Val: 91) and Group LRI consisted of 315 patients (LRI-El: 265; LRI-Val: 50). The model obtained for EFW was: EFW=-8.277+2.146xBPDxACxFL-2.449xFLxBPD². The performances of other models were significantly worse than those obtained with our formula. Equations for the prediction of conditional percentiles of EFW were derived from the longitudinal observation of patients of subgroup LRI-El and validated with data from subgroup LRI-Val. We described a method for customization of longitudinal reference intervals of EFW obtained using formulas generated from a sample of the Brazilian population.

  12. Identification of an elaborate NK-specific system regulating HLA-C expression.

    Full Text Available The HLA-C gene appears to have evolved in higher primates to serve as a dominant source of ligands for the KIR2D family of inhibitory MHC class I receptors. The expression of NK cell-intrinsic MHC class I has been shown to regulate the murine Ly49 family of MHC class I receptors due to the interaction of these receptors with NK cell MHC in cis. However, cis interactions have not been demonstrated for the human KIR and HLA proteins. We report the discovery of an elaborate NK cell-specific system regulating HLA-C expression, indicating an important role for HLA-C in the development and function of NK cells. A large array of alternative transcripts with differences in intron/exon content are generated from an upstream NK-specific HLA-C promoter, and exon content varies between HLA-C alleles due to SNPs in splice donor/acceptor sites. Skipping of the first coding exon of HLA-C generates a subset of untranslatable mRNAs, and the proportion of untranslatable HLA-C mRNA decreases as NK cells mature, correlating with increased protein expression by mature NK cells. Polymorphism in a key Ets-binding site of the NK promoter has generated HLA-C alleles that lack significant promoter activity, resulting in reduced HLA-C expression and increased functional activity. The NK-intrinsic regulation of HLA-C thus represents a novel mechanism controlling the lytic activity of NK cells during development.

    Graphical abstract: - Highlights: • Nitrogen doped amorphous carbon films were deposited by DC reactive plasma femtosecond (fs) -PLD and conventional fs-PLD. • High nitrogen content in plasma assisted films. • More ordered sp2 rich graphitic clusters both in terms of structural and topological order. • Correlation length La of the clusters increases with nitrogen incorporation. • Formation of CN bonds at the expense of CC bonds with N content. • At the highest nitrogen concentration, terminal C≡N groups are incorporated in the film. • Correlation between film composition and plasma process. - Abstract: Amorphous carbon nitride (a-C:N) thin films are a interesting class of carbon-based electrode materials. Therefore, synthesis and characterization of these materials have found lot of interest in environmental analytical microsystems. Herein, we report the nitrogen-doped amorphous carbon thin film elaboration by femtosecond pulsed laser deposition (fs-PLD) both with and without a plasma assistance. The chemical composition and atomic bonding configuration of the films were investigated by multi-wavelength (MW) Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and electron energy-loss spectroscopy (EELS). The highest nitrogen content, 28 at.%, was obtained with plasma assistance. The I(D)/I(G) ratio and the G peak position increased as a function of nitrogen concentration, whereas the dispersion and full width at half maximum (FWHM) of G peak decreased. This indicates more ordered graphitic like structures in the films both in terms of topological and structural, depending on the nitrogen content. EELS investigations were correlated with MW Raman results. The interpretation of XPS spectra of carbon nitride films remains a challenge. Plasma assisted PLD in the femtosecond regime led to a significant high nitrogen concentration, which is highlighted on the basis of collisional processes in the carbon plasma plume interacting with the nitrogen

    The aim of this work was to study surface reactivity of silica nanoparticles through physical and chemical properties of sols and coatings. Applications are numerous and they are illustrated in this work by optical coating preparation for laser components and chemical gas sensor development for nitroaromatics detection. On one hand, protocol synthesis of colloidal silica sols has been developed in water medium using sol-gel process (0 to 100 w%). These sols, so-called BLUESIL, are time-stable during at least one year. Homogeneous coatings having thickness fixed to 200 nm, have been prepared on silica substrate and show high porosity and high transparence. Original films have been developed using catalytic curing in gas atmosphere (ammonia curing) conferring good abrasive resistance to the coating without significant properties modification. In order to reduce film sensitivity to molecular adsorption (water, polluting agents... ), specific BLUESIL coatings have been prepared showing hydrophobic property due to apolar species grafting onto silica nanoparticles. Using this route, coatings having several functional properties such as transparence, hydrophobicity, high porosity and good abrasive resistance have been elaborated. On the other hand, we show that colloidal silica is a material specifically adapted to the detection of nitro aromatic vapors (NAC). Indeed, the use of colloidal silica as chemical gas sensor reveals very high sensitivity, selectivity to NAC compared to Volatile Organic Compound (V.O.C) and good detection performances during one year. Moreover, chemical sensors using functionalized colloidal silica have exhibited good results of detection, even in high humidity medium (≥70 %RH). (author)

    2016-01-01

    Full Text Available The article presents design engineering methods for the high-voltage pulse installations of technological purpose for disinfection of drinking water, sewage, and edible liquids by high field micro- and nanosecond pulsing exposure. Designing potentialities are considered of the principal elements of the high-voltage part and the discharge circuit of the installations towards assuring the best efficient on-load utilization of the source energy and safe operation of the high-voltage equipment. The study shows that for disinfection of drinking water and sewage it is expedient to apply microsecond pulse actions causing the electrohydraulic effect in aqueous media with associated complex of physical processes (ultraviolet emission, generation of ozone and atomic oxygen, mechanical compression waves, etc. having detrimental effect on life activity of the microorganisms. In case of disinfecting edible liquids it is recommended to use the nanosecond pulses capable of straight permeating the biological cell nucleus, inactivating it. Meanwhile, the nutritive and biological values of the foodstuffs are saved and their organoleptic properties are improved. It is noted that in elaboration process of high-frequency pulse installations special consideration should be given to issues of the operating personnel safety discipline and securing conditions for the entire installation uninterrupted performance. With this objective in view the necessary requirements should be fulfilled on shielding the high- and low-voltage installation parts against high-frequency electromagnetic emissions registered by special differential sensors. Simultaneously, the abatement measures should be applied on the high-voltage equipment operational noise level. The authors offer a technique for noise abatement to admissible levels (lower than 80 dB A by means of coating the inside surface with shielded enclosure of densely-packed abutting sheets of porous electro-acoustic insulating

    Full Text Available The aim of virgin olive oil elaboration process is to obtain the highest recovery of the best quality oil from the fruits. The aim of the researchers is to understand the key elements that allow to modulate the complex series of physical, physico-chemical, chemical and biochemical transformations in order to develop innovative and sustainable plant solutions able to increase simultaneously both yield and quality of product. The basic principles applied also in the newest olive oil industrial plants still follow the technical knowledge which have been empirically learned by humans thousands of years ago. In fact, it is well known that three factors, mixing, water adding and warming, are the three macroscopic driving forces able to favour the separation of the oily phase from the mass of crushed olives. In this consolidated scenario, can new elements emerge? The whole process should be considered more than a simple extraction of the oil present in fruit cells, but a complex elaboration of a product, which is depleted and enriched of both constitutive and neo-synthesised compounds through complex phenomena only in part discovered. In fact, while it is evident that numerous studies have been conducted to elucidate the behaviour of olive paste during virgin olive oil extraction process, a key conclusion is that the current level of understanding can be improved further by means the development of more rigorous researches with more focused targets aimed to understand the rheological changes, the coalescence phenomena, the changes in hydrophobic and hydrophilic phenomena, the partition equilibrium of minor compounds between aqueous and oily phases and, last but not least, the favourable and unfavourable enzymatic reactions. This paper provides an analysis of the present research field and its strengths and weaknesses are discussed. Potentially important future directions for research are also proposed.

  17. Indigenous healing practice: ayahuasca. Opening a discussion.

    Prue, Robert; Voss, Richard W

    2014-01-01

    This essay frames an invitation to pastoral counselors and pastoral theologians to examine connections and perhaps interactions between themselves and traditional shamanic healers who use ayahuasca in their healing ceremonies. Indigenous people in South America have used ayahuasca for centuries, and the ritual has become common among the mestizo populations in urban areas of the Amazon, particularly as a curing ritual for drug addiction (Dobkin de Rios, 1970; Moir, 1998). Like peyote in the United States (Calabrese, 1997) ayahuasca use amongst the indigenous people of the Amazon is a form of cultural psychiatry. A review of the literature reveals very little commentary or discussion of shamanic practice in Pastoral Counseling (Pastoral Theology). The scant literature identifies an antithetical relationship at best. The current authors wonder about the possibility of to including shamanic practices in the context of pastoral counseling? This essay seeks to provide some basic information about the ritual use of ayahuasca and to offer a rationale for pastoral counselors to engage in a dialogue about its utility.

    Elderly minority patients are less likely to receive influenza vaccination and colorectal cancer screening than are other patients. Communication between primary care providers (PCPs) and patients may affect service receipt. Encounters between 7 PCPs and 18 elderly patients were observed and audiotaped at 2 community health centers. Three investigators coded transcribed audiotapes and field notes. We used qualitative analysis to identify specific potential barriers to completion of preventive services and to highlight examples of how physicians used patient-centered communication and other facilitation strategies to overcome those barriers. Sharing of power and responsibility, the use of empathy, and treating the patient like a person were all important communication strategies which seemed to help address barriers to vaccination and colonoscopy. Other potential facilitators of receipt of influenza vaccine included (1) cultural competence, (2) PCP introduction of the discussion, (3) persistence of the PCP (revisiting the topic throughout the visit), (4) rapport and trust between the patient and PCP, and (5) PCP vaccination of the patient. PCP persistence as well as rapport and trust also appeared to facilitate receipt of colorectal cancer screening. Several communications strategies appeared to facilitate PCP communications with older patients to promote acceptance of flu vaccination and colorectal cancer screening. These strategies should be studied with larger samples to determine which are most predictive of compliance with prevention recommendations.

    2013-11-01

    The single-band α-model of superconductivity (Padamsee et al 1973 J. Low Temp. Phys. 12 387) is a popular model that was adapted from the single-band Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity mainly to allow fits to electronic heat capacity versus temperature T data that deviate from the BCS prediction. The model assumes that the normalized superconducting order parameter Δ(T)/Δ(0) and therefore the normalized London penetration depth λL(T)/λL(0) are the same as in BCS theory, calculated using the BCS value αBCS ≈ 1.764 of α ≡ Δ(0)/kBTc, where kB is Boltzmann’s constant and Tc is the superconducting transition temperature. On the other hand, to calculate the electronic free energy, entropy, heat capacity and thermodynamic critical field versus T, the α-model takes α to be an adjustable parameter. Here we write the BCS equations and limiting behaviors for the superconducting state thermodynamic properties explicitly in terms of α, as needed for calculations within the α-model, and present plots of the results versus T and α that are compared with the respective BCS predictions. Mechanisms such as gap anisotropy and strong coupling that can cause deviations of the thermodynamics from the BCS predictions, especially the heat capacity jump at Tc, are considered. Extensions of the α-model that have appeared in the literature, such as the two-band model, are also discussed. Tables of values of Δ(T)/Δ(0), the normalized London parameter Λ(T)/Λ(0) and λL(T)/λL(0) calculated from the BCS theory using α = αBCS are provided, which are the same in the α-model by assumption. Tables of values of the entropy, heat capacity and thermodynamic critical field versus T for seven values of α, including αBCS, are also presented.

    Full Text Available Introduction: the article is concerned with the development of competence when teaching students innovative activity. The analysis of bachelor’s degree programmes in engineering and technology demonstrates the absence of competencies for innovation training. The curricula of the Russian universities do not contain any academic disciplines for teaching innovation as well as there is no definition of “engineering activities”, and “innovation”. Nethertheless the qualification requirements describe some separate components such as R&D, implementation and use of technical and technological innovations implying management of intellectual activity and its results for all occupations, hence mandatory training of bachelor degree students in innovative activities. Materials and Methods: the authors used: a theoretical methods: analysis of philosophical, scientific, technical, engineering, psychological and educational literature; analysis and extrapolation of the research results and teaching experience; modeling of pedagogical situations, analysis of educational standards, foreign and domestic programs of technical training, textbooks and manuals; b scientific methods: generalization, classification, ordering, compare, comparison, modeling; c methods of special research: a system-element method, system-structural and system-functional analysis of the training content, analysis and generalization of pedagogical experience in teaching courses at universities; d experimental and psychology diagnostic methods. Results: the authors developed and implemented the method of teaching engineering students innovative activities based on adding flexible module to core curriculum, a case study of the National Research Mordovia State University. Discussion and Conclusions: the results of the research underscore the significance of the innovation competence by including innovative training module into structure of technical disciplines, as well as specify the

    Full Text Available Discussion pedagogy is part of a larger curricular goal that intersects the two aspirations of diversity of perspectives and democratic inquiry in that it challenges stereotypes and assumptions through student discourse. Yet, teaching with discussion is a complex and sometimes ambiguous endeavor that leaves instructors feeling pulled between desirable, but seemingly contradictory, goals. This article discusses these paradoxes of instructional choices and student outcomes that instructors may negotiate through polarity management, a theoretical framework that focuses on values that are diametrically opposed, yet interdependent upon each other. Implications of polarity management for discussion pedagogy are highlighted.

Are they able to elaborate their own rules? Or is it only a theoretical approach that is unviable to put into practise? In any case, what level of responsibility and autonomy are they able to assume in the functioning of the classroom? The learning of rules in the classroom constitutes a real experience, very close to the experience and the interests of the pupils, that permits them to work on values such as: responsibility, respect, participation, dialogue and democracy. At the same time, it teaches them to participate in class meetings, work in small groups, formulate proposals and arrive to a consensus through dialogue and negotiation. The experimental research in this field has demonstrated on numerous occasions that when the teacher generates opportunities to reflect on coexistence in the classroom and involve their pupils, it produces a clear tendency to decrease disruptive behaviour.

  9. Biological dosimetry in radiological protection: dose response curves elaboration for 60Co and 137Cs

    1997-01-01

    Ionizing radiation sources for pacific uses are being extensively utilized by modern society and the applications of these sources have raised the probability of the occurrence of accidents. The accidental exposition to radiation creates a necessity of the development of methods to evaluate dose quantity. This data could be obtained by the measurement of damage caused by radiation in the exposed person. The radiation dose can be estimated in exposed persons through physical methods (physical dosimetry) but the biological methods can't be dispensed, and among them, the cytogenetic one that makes use of chromosome aberrations (dicentric and centric ring) formed in peripheral blood lymphocytes (PBL) exposed to ionizing radiation. This method correlates the frequency of radioinduced aberrations with the estimated absorbed dose, as in vitro as in vivo, which is called cytogenetic dosimetry. By the introduction of improved new techniques in culture, in the interpretation of aberrations in the different analysers of slides and by the adoption of different statistical programs to analyse the data, significant differences are observed among laboratories in dose-response curves (calibration curves). The estimation of absorbed dose utilizing other laboratory calibration curves may introduce some uncertainties, so the International Atomic Energy Agency (IAEA) advises that each laboratory elaborates your own dose-response curve for cytogenetic dosimetry. The results were obtained from peripheral blood lymphocytes of the healthy and no-smoking donors exposed to 60 Co and 137 Cs radiation, with dose rate of 5 cGy.min. -1 . Six points of dose were determined 20,50,100,200,300,400 cGy and the control not irradiated. The analysed aberrations were of chromosomic type, dicentric and centric ring. The dose response curve for dicentrics were obtained by frequencies weighted in liner-quadratic mathematic model and the equation resulted were for 60 Co: Y = (3 46 +- 2.14)10 -4 cGy -1 + (3

    Full Text Available In the Walloon Region (Belgium, 239 sites have been selected to be included in the Natura 2000 network. The next step is to write designation acts in order to legally protect these 221,000 ha. In this pilot study, a designation act was elaborated for a Natura 2000 site of 2,569 ha and located in the Lesse-and-Lomme area within the Calestienne region. Although the site includes 40 ha of calcareous grasslands, characterised by an exceptional flora and fauna, this habitat is very threatened by abandonment and fragmentation.The methodology used to elaborate the designation act is presented with respect to calcareous grassland. Firstly, in spring and summer 2003, an accurate map of natural habitats was produced, with every single patch of calcareous grassland being mapped. Information was also collected in order to evaluate conservation status. Based on this information, conservation status was then assessed with respect to three different criteria: (1 integrity of the cortege species, (2 habitat structure and (3 degradations. Thirdly, the site was divided into objective zones according to the different habitats and species of Community interest found in the site. Hence, an objective zone was delineated for calcareous grasslands. This objective zone was then divided in several management units. Finally, at these different spatial levels (site, objective zone, management unit, management measures were suggested. As a result, in the draft designation act, the target is to maintain or restore 230 ha of calcareous grassland, instead of the existing 40 ha. This ambitious target requires large-scale restoration and an efficient grazing scheme. These will need important resources for their successful implementation

It was in August of 2008 that the first AAPM Workshop on Becoming a Better Teacher of Medical Physics was held, organized and run by Bill Hendee. This was followed up in July of 2010 with a summer school on the same topic, again organized by Bill. There has been continued interest in alternate approaches to teaching medical physics since those initial gatherings. The momentum established by these workshops is made clear each year in the annual Innovation in Medical Physics Education session, which highlights work being done in all forms of medical physics education, from one-on-one residencies or classroom presentations to large-scale program revisions and on-line resources for international audiences. This symposium, presented on behalf of the Education Council, highlights the work of three finalists from past Innovation in Education sessions. Each will be presenting their approaches to and innovations in teaching medical physics. It is hoped that audience members interested in trying something new in their teaching of medical physics will find some of these ideas and approaches readily applicable to their own classrooms.

    Online discussion has become one of the important strategies for the teacher to teach the students to think critically when conveying their ideas and become more proactive and creative. In this paper, padlet online discussion communication was conducted to examine its effectiveness in enhancing critical thinking. In this study, there are two types of critical thinking: macro and micro critical thinking. A total of 70 Universiti Utara Malaysia Management Foundation Programme students involved in this experimental research design. The students in treatment class are divided to few groups. Every group uses padlet online discussion to discuss the topic given. All the group members discuss and write their ideas in padlet. Ideas that are posted in padlet will be displayed in front of the class so that the entire group in the treatment class could see the given ideas. Paul's (1993) model was used to analyze student's macro and micro critical thinking in padlet online discussion and communication. The finding shows that students who used padlet online discussion backchannel communication have greater macro and micro critical thinking level than students who do not use online discussion.

    Horcajo, Javier; Luttrell, Andrew

    2016-06-01

    This experiment analyzed whether attitudes toward the legalization of several doping behaviors would resist change and predict behavioral intentions when they were initially formed through thoughtful (i.e., high elaboration) versus nonthoughtful (i.e., low elaboration) processes. Participants were randomly assigned first to a persuasive message either against or in favor of the legalization, which they read with relatively high or low degrees of deliberative thinking. Attitudes and intentions regarding legalization were assessed following that message. Next, each participant received a second message that was opposed to the first one, serving as an attack against the attitude that participants had just formed. Finally, attitudes were again assessed. As hypothesized, participants showed greater attitude-consistent intentions when they formed their initial attitudes through thoughtful (vs. nonthoughtful) consideration of the first message. Moreover, the second message resulted in greater resistance to attitude change when participants formed their initial attitudes through thoughtful (vs. nonthoughtful) processes.

    Elaboration of the evaluation guidelines for activities implemented jointly (AIJ) was researched to prevent the earth from warming. AIJ is the means to globally promote countermeasures against global warming cost-effectively by optimally combining every country`s technology, know-how and fund. AIJ was established in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change in March, 1995. The pilot phase of AIJ is first carried out by voluntary workers jointly with developing countries under the agreement of the parties. The current situation of activities is reported in COPI as materials for evaluation of AIJ. To promote AIJ, elaboration of the evaluation guidelines for AIJ Japan program is also necessary for Japan. This research arranged the contents of the evaluation guidelines and the method of classifying projects for AIJ Japan program, and carried out some case studies of promising projects to reduce greenhouse gas emission for future proposal. 3 figs., 31 tabs.

    2004-06-01

    Full Text Available This paper presents one of five categories of findings of a qualitative study of students' experiences of challenges encountered in a web-based graduate program. The findings relate to the category of experiences with online asynchronous discussions. Data collection relied on a discussion, questionnaire and interview all conducted within WebCTTM. The category's findings were grouped into four sub-categories of challenges as follows: student behaviour; text-only, online communication; purpose and quality of the discussion; and forum features. Challenges related to students' behaviour included domination of the discussion by individual students or groups of students resulting in feelings of exclusion, frustration and inadequacy. Text-only communication caused difficulties related to misinterpretation and conveying and deriving intent. Challenges related to the purpose and value of the discussion resulted from low quality and high quantities of postings to meet grade requirements. Technical features that presented challenges included the inability to delete messages.

    Full Text Available This paper presents a novel approach to a problem of the design feature library elaboration. As a tool of the design feature library development CNC machining cycles were proposed. Because of the great number of commercially available CNC machine controllers, with different CNC machining cycles definitions, it was necessary to make a decision about a research methodological framework, it is the selected CNC machine controller. Taking into account the criterion of popularity as the research framework the selected group of Sinumerik CNC machine controllers was chosen. Presented in the paper idea of the feature library development is based on an assumption saying that it is possible to find a relationship between a particular CNC machining cycle and the simple design feature or even compound design features. Identified, thanks to this assumption, set of the design features could be the base for elaboration of the design feature library. This solution, it is the feature library next gave opportunity for elaboration of the feature based design modelling module (FBDMM working in the SIEMENS NX system environment. Hence, the FBDMM module can support both a designer and CNC machine programmer which is possible due to received in the module modelling paradigm. In FBDMM module the removal feature based modelling technique is received.

    Full Text Available The purpose of this work was to develop an elaboration process of fried-salted soybean and to determine the chemical composition, consumer acceptance and sensory description of the product. Different fried-salted soybean products were obtained under different temperature and time conditions by maceration in water, roasting and frying. Four of the best products were selected and evaluated by consumers (overall, color and texture acceptances: FSS1, FSS2, FSS3 and FSS4. The product with the highest consumer acceptance (7 = “like moderately” in a hedonic scale of 9 points was the one obtained by maceration at 100°C during 10 min and fried at 170°C for 5 min (FSS3. Proximate and fatty acid composition along with sensory attribute intensity ratings from descriptive analyses were determined on the fried-salted soybean with the highest consumer acceptance (FSS3. Proximate and fatty acid composition were also determined in raw soybeans. FSS3 had lower percentages of moisture and proteins, and higher lipids and carbohydrates than raw soybean. The use of sunflower oil in the frying process improved the fatty acid composition of the soybean product. Sensory attributes from descriptive analyses that were detected in high intensity ratings for the product were roasted, salty, crunchiness, hardness, brown color and gloss. This product is neither commonly consumed nor easily available in markets. It could be promoted to be consumed as a snack because of its high nutritional and sensory quality.

    2003-01-01

    At the present time the technique of deposit of laser ablation is used to produce different types of thin films. At the moment in the National Institute of Nuclear Research (ININ) it is carried out an investigation on the thermoluminescent response of thin films of CN x with possible application in dosimetry of electromagnetic radiation. Under this context, the present work is part of this investigation and has as objective to characterize thin films of CN x by means of Infrared spectrometry and nuclear analytical techniques. The deposits were elaborated by laser ablation under different such experimental conditions as: pressure of Nitrogen in the system (3 x 10 -3 and 7.5 X 10 -2 Torr), Distance target-substrate (3 and 5 cm) and density of incident energy in the target (from 17.5 up to 23.8 J/cm 2 ). Graphite of high purity was used like target and the deposits were made on their substrates of intrinsic silicon (100). By means of infrared spectrometry by Fourier Transform (Ftir) the type of bonds which are in the structure of the films of CN x were determined. The spectra of this type of samples present in general four characteristic bands related with different types of bonds among the elements C, O, H, N such as: C-C, C-N, C-H, N-H, O-H, C=N, C≡N, among others. It was carried out a semi quantitative study of the samples isolating each band of the total infrared spectra and making a comparison between their intensities and forms. This study allowed to observe that there is a dependence of the structure of the films with regard to the time, since mainly bonds of the type Sp 3 between Hydrogen and Carbon (C-H) they presented a remarkable variation in intensity, increasing as it lapsed the time until reaching to a stabilization where the bonds already not varying. This increase probably is due to the absorption of water of the atmosphere, although one has seen in the literature that the incorporation of this compound in this type of samples affects mainly to the

    Conditions associated to the consumption of gluten have emerged as a major health care concern and the treatment consists on a lifelong gluten-free diet. Providing safe food for these individuals includes adapting to safety procedures within the food chain and preventing gluten cross-contamination in gluten-free food. However, a gluten cross-contamination prevention protocol or check-list has not yet been validated. Therefore, the aim of this study was to perform the content validation and semantic evaluation of a check-list elaborated for the prevention of gluten cross-contamination in food services. The preliminary version of the check-list was elaborated based on the Brazilian resolution for food safety Collegiate Board Resolution 216 (RDC 216) and Collegiate Board Resolution 275 (RDC 275), the standard 22000 from the International Organization for Standardization (ISO 22000) and the Canadian Celiac Association Gluten-Free Certification Program documents. Seven experts with experience in the area participated in the check-list validation and semantic evaluation. The criteria used for the approval of the items, as to their importance for the prevention of gluten cross-contamination and clarity of the wording, was the achievement of a minimal of 80% of agreement between the experts (W-values ≥ 0.8). Moreover, items should have a mean ≥4 in the evaluation of importance (Likert scale from 1 to 5) and clarity (Likert scale from 0 to 5) in order to be maintained in the instrument. The final version of the check-list was composed of 84 items, divided into 12 sections. After being redesigned and re-evaluated, the items were considered important and comprehensive by the experts (both with W-values ≥ 0.89). The check-list developed was validated with respect to content and approved in the semantic evaluation.

    Young people's engagement in political discussions with parents and friends represents a significant component of the political socialization process and can be seen as an activity where they learn some very basic democratic skills. Based on data from qualitative interviews and a questionnaire...... survey, this article explores how young people experience political discussions in their everyday life. Our data indicate that young people who feel that their father, mother or friends, respectively, hold more distant political views are less likely to engage in political discussions with each of them....... These findings support previous studies in political communication suggesting that people tend to avoid social situations where political disagreements are likely to appear. Furthermore, the results show that there are significant gender differences when analysing the role of the parents as political discussion...

    2012-01-01

    Utilization of nuclear energy is increasingly necessary not only because of the increasing energy consumption but also because of the controls on greenhouse emissions against global warming. To keep step with such demands, advanced reactors are now world widely under development with the aims of highly economical advances, and enhanced safety. Recently, further elaborating is encouraged on the research and development program for Generation IV (GEN IV) reactors, and in collaboration with other interested countries through the Generation IV International Forum (GIF). Sodium cooled Fast Reactor (SFR) is a strong contender amongst the GEN IV reactor concepts. Korea also takes part in that program and plans to construct demonstration reactor of SFR. SFR is under the development for a candidate of small modular reactors, for example, PRISM (Power Reactor Innovative Small Module). Understanding of safety analysis approach has also advanced by the demand of increasing comprehensive safety requirement. Reviewing the past development of the licensing and safety basis in the advanced reactors, such approaches seemed primarily not so satisfactory because the reference framework of licensing and safety analysis approach in the advanced reactors was always the one in water reactors. And, the framework is very plant specific one and thereby the advanced reactors and their frameworks don't look like a well assorted couple. Recently as a result of considerable advances in probabilistic safety assessment (PSA), risk informed approaches are increasingly applied together with some of the deterministic approaches like as the ones in water reactors. Technology neutral framework (TNF) can be said to be the utmost works of such risk informed approaches, even though an intensive assessment of the applicability has not been sufficiently accomplished. This study discusses the viable safety analysis approaches for the urgent application to the construction of pool type SFR. As discussed in

The authors first discuss issues related to code selection criteria (author classification, topic classification, and so on), and propose an overview and a discussion of linguistic models. They also comment how diagrams illustrating relationships between words are built up, and propose a diagram representation example which includes different concepts such as conditions, properties, object, tools or processes (for example hardness for a steel, batch processing for a condition, or sintering for a process), and also the introduction of negation. Then, the authors address how basic concepts can be highlighted, describe how key sentences can be built up, and propose an example analysis in the case of a published article dealing with nuclear reactors (in this case, the study of a liquid-metal neutron absorber for the control of a gas-cooled power reactor). Perspectives of evolution are finally discussed

    2011-01-01

    Full text: Senior nuclear experts today offered several recommendations on how the International Atomic Energy Agency (IAEA) can further develop its operational safety review services. The IAEA hosted a technical meeting on the Evaluation of Effectiveness of Operational Safety Review Services and their Future Evolution at the Agency's headquarters in Vienna from 1 to 4 November 2011. Representatives from nuclear regulatory bodies, nuclear utilities, nuclear power plants and technical support organisations from 19 IAEA Member States and the World Association of Nuclear Operators (WANO) took part in the meeting. It provided a platform for the exchange of information, experience and lessons learned from the operational safety review missions performed during 2008-2011. The meeting also included discussion of expectations for the future evolution of these services. ''This week's meeting demonstrated the response of the IAEA's Member States to the lessons learned from the Fukushima accident. Nations must constantly strive to improve their nuclear safety practices, and the IAEA review services provide an excellent tool to assess their progress,'' said Miroslav Lipar, head of the IAEA's Operational Safety Section. The IAEA's operational safety review services assess the operational safety performance of nuclear power plants by conducting peer reviews using the requirements of IAEA Safety Standards. The longest running safety review service, the Operational Safety Review Team (OSART) programme, was established in 1982 and has provided advice and assistance to Member States in 165 missions to enhance the safety of nuclear power plants during commissioning and operation. Other review services available in the area of operations evaluate operating experience feedback, safe long-term operation and safety culture. The IAEA Action Plan on Nuclear Safety includes actions focused towards strengthening the existing IAEA peer reviews by incorporating lessons learned and improving

    The sea water is a possible uranium source. The uranium concentration in it was estimate at 14 nM in the open oceans, in uranyl ion UO 2 2+ . Among the possible electrode materials to extract the uranium from sea water, the polypirrole doped with hexasulfon calix[6]arene (PPy/1) allows the elaboration of an electrochemical system of the uranium detection and extraction. This study aims to detail the electrochemical characterization of the PPy/1, in particular its structural properties and its anti-corrosion properties. (A.L.B.)

    Materials for the reactor cores of the fourth generation will need materials supporting high temperatures with fast neutrons flux. SiC{sub f}/SiC ceramics are proposed. One of the possible elaboration process is to fill SiC fiber piece with nano particles SiC powder and to strengthen by sintering. The aim of this thesis is to obtain a nano structured SiC ceramic as a reference for the SiC{sub f}/SiC composite development and to study the influence of the fabrication parameters. (A.L.B.)

    Morbidity and mortality conferences in residency programs are intended to discuss adverse events and errors with a goal to improve patient care. Little is known about whether residency training programs are accomplishing this goal. To determine the frequency at which morbidity and mortality conference case presentations include adverse events and errors and whether the errors are discussed and attributed to a particular cause. Prospective survey conducted by trained physician observers from July 2000 through April 2001 on 332 morbidity and mortality conference case presentations and discussions in internal medicine (n = 100) and surgery (n = 232) at 4 US academic hospitals. Frequencies of presentation of adverse events and errors, discussion of errors, and attribution of errors. In internal medicine morbidity and mortality conferences, case presentations and discussions were 3 times longer than in surgery conferences (34.1 minutes vs 11.7 minutes; P =.001), more time was spent listening to invited speakers (43.1% vs 0%; Pinternal medicine case presentations included adverse events (37 [37%] vs 166 surgery case presentations [72%]; Perrors causing an adverse event (18 [18%] vs 98 [42%], respectively; P =.001). When an error caused an adverse event, the error was discussed as an error less often in internal medicine (10 errors [48%] vs 85 errors in surgery [77%]; P =.02). Errors were attributed to a particular cause less often in medicine than in surgery conferences (8 [38%] of 21 medicine errors vs 88 [79%] of 112 surgery errors; Perrors, conference leaders in both internal medicine and surgery infrequently used explicit language to signal that an error was being discussed and infrequently acknowledged having made an error. Our findings call into question whether adverse events and errors are routinely discussed in internal medicine training programs. Although adverse events and errors were discussed frequently in surgery cases, teachers in both surgery and internal

  17. Conflicting perspectives compromising discussions on cardiopulmonary resuscitation.

    Groarke, J

    2010-09-01

    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    We argue that psychological and contextual factors play important roles in bringing about, facilitating, and escalating violent conflict. Yet rather than conclude that violent conflict is inevitable, we believe psychology's contributions can extend beyond understanding the origins and nature of violent conflict, to promote nonviolence and peace. In this article, we summarize psychological perspectives on the conditions and motivations underlying violent conflict. Drawing on this work, we then discuss psychological and contextual factors that can mitigate violence and war and promote nonviolence and peace.

  16. Discussion on alternative systems for film radiography

    International Nuclear Information System (INIS)

    Vaessen, B.; Perdieus, P.; Willems, P.

    1997-01-01

    Film radiography is a well-established NDT technique and an accepted method for quality assurance. Recently, so-called new developments have been introduced to the market as alternatives for film radiography. Examples are fluorescent screen/film systems, cost containment films, wide-latitude films and storage phosphor plate systems. The authors have evaluated these systems and their applicability for NDT, taking into account factors such as sensitivity (image quality), speed, handling, portability, reliability. In this paper, the value and applicability for the NDT market of two of these methods, namely fluorescent screen systems and storage phosphor plates, are discussed, in comparison with conventional film techniques. Both technologies have been developed and are available within Agfa-Gevaert, therefore we can overview all aspects for the Agfa strategic NDT market and discuss Agfa's strategy regarding these technologies; the conclusion is that all that is new is not necessarily beautiful.

  18. Hermeneutics and observation--a discussion.

    Science.gov (United States)

    Nåden, Dagfinn

    2010-03-01

    This study deals with hermeneutics and observation. The purpose is to discuss some central concerns of hermeneutics in relation to observation as a research method. Attention is centred on the hermeneutic process, preunderstanding, understanding, sensitivity, the fore-conception of completeness and language. Examples from an observation study are presented. The study ends with a discussion of the importance of proceeding without haste and of silence in observational hermeneutic research. The researcher must allow oneself to be influenced by these qualities if the observations are to be undertaken in a hermeneutic spirit. Physical time must be of lesser importance than inner time. The possibility then exists for the researcher to wander the hermeneutic spiral to the greatest depth possible.

    2002-12-01

    This document aims at building up a tool which can be used by local actors in order to promote dialogue with inhabitants before the development of a wind energy project, and then to favour a better social and territorial implementation of these projects. It is mainly based on returns on experience and on other successful achievements. The authors propose a brief history of wind energy, a presentation of different types of present wind turbines, a brief discussion of electric power production and of rules for wind plants. They discuss the prospective of the energy issue and the choice made for renewable energies, present an overview of the development framework for renewable energies in France, describe the wind energy context in France (limits of the regulatory framework, a social acceptance to be strengthened, the often forgotten dialogue), present wind energy as a new element of a territory, and formulate some proposals for the building up of shared rules of the game. The second part is a toolbox which proposes several sheets which address various issues to be addressed during a project, or present some successful examples

    Aebersold, M.

    2004-01-01

    The round table discussions of the first session of the Belgium Workshop addressed the following questions: - Accepting or refusing a person, an institution or a grouping as a legitimate Stakeholder who makes the decision and how? - How are the local partnerships built and organised? - How to obtain community support for the partnership's legitimate decisions/findings? - Experience teaches that no decision is reached solely by formal and legal processes. What role do informal processes play? - How can the informal procedures be accepted? Do they need to be made explicit? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. After the discussion, each table's findings were reported to the plenary. Most of the discussion concerned the local partnerships. Important findings were that the statutes for the partnerships were developed by the partnerships themselves and there were no legally binding rules handed down by the federal level. The partnerships are part of an informal process. A legally binding participation (i.e. within the EIA) will be initiated at a later stage. As the partnerships function outside of the formal legal procedure, they can function in a more flexible way. It was noted that the partnerships make recommendations, but it is not clear what the government will do with these recommendations. It was also argued that the process may cause conflicts between neighboring communities. As in other contexts visited by the FSC, the importance of the right of veto of the community was stressed, although this may cause a conflict between technical suitability and social acceptance. Access of the community to the local partnership is necessary. Finally it was accepted that time is needed to explain the recommendations to the broader community before any decisions are taken.

  7. Nuclear waste under glass, further discussion

    Science.gov (United States)

    O'Keefe, J. A.; Barkatt, A.; Glass, B. P.; Alterescu, S.

    J. J. Crovisier and J. Honnorez [1988] discuss an article by W. W. Maggs, “Mg May Protect Waste Under Glass” [Maggs, 1988] summarizing work by A. Barkatt (Catholic University, Washington, D.C.), B. P. Glass (University of Delaware, Newark), and S. Alterescu and J. A. O'Keefe (NASA/GSFC, Greenbelt, Md.). We found that seawater is orders of magnitude less corrosive t h an fresh water in attacking tektite glass; traced the protective effect to the presence of magnesium, at a level of about 1.3 g/L in seawater; and suggested that the effect might be useful in protecting nuclear waste glasses from corrosion.Crovisier and Honnorez first make the point that the rate of corrosion of glass is, in principle, a function of the ratio of surface area 5 to the effective volume V. This concept, which is usually discussed in American literature under the name of S/V effects, is discussed by Crovisier and Honnorez in terms of the “permeability of the environment.” These effects have been carefully considered throughout our work (see, for example, Barkatt et al. [19867rsqb;). It turns out that in the sea the effective S/V is so small that the effects referred to by Crovisier and Honnorez can be ignored.

  8. Argumentation in socio-scientific discussions

    2013-12-01

    Full Text Available This study aimed to understand the development of the argument in socio-scientific discussions in Chemistry lessons. Were investigated classes of three teachers in public schools in high school of the Federal District – Brazil to identify the occurrence of argumentative situations,actions favorable to the development of the arguments made by the teachers, and the presence of scientific knowledge on the composition of the arguments developed. The monitoring of the classes involved videotaping lessons; field notes; interview in focus groups with students and individually with each one of the teachers; and the application of a questionnaire for the teachers. The results showed that the teachers have established an opportune environment to argumentative practice when promoted socio-scientific discussions, facilitate the verbalization, and use strategies aimed at the participation of students as interlocutors in discussion and interaction. On the other hand, it was found that the argumentative situations identified were not very significant and that the teachers had difficulties in developing specific verbal actions directed to the establishment of the argumentation and for the mobilization of scientific knowledge in the construction of arguments.

  9. Islamophobia? The German Discussion about Islamophobia

    Directory of Open Access Journals (Sweden)

    Astrid Bötticher

    2009-08-01

    Full Text Available Islamophobia is a term which is relatively new in the world of social science; it is a neologism. Kofi Annan has warned about it but there is not a clear, undoubted concept to it yet – and it is questionable if there ever will be, especially if one looks into the German controversy about the term. The German discussion is not unique though, and must fall into the pattern of wider, European discussion about the Islamic minority. Prominent figures of Islamic hatred in Europe are for instance Oriana Fallaci and Brigitte Bardot. Against them, there stands a more liberal community that does not want to follow the language of violence and hatred. Two different standpoints are the main poles of discussion. One group wants to use Islamophobia as a concept, the other group opposes the term. In between, there is the scientific concept of Islamophobia that is threatened to be pulverized before it is even fully conceptualized. In the middle position there are also intellectuals known as Islamic reformers who argue that Islamophobia should be replaced by the term Islam-critique.

  10. Adolescents discuss themselves and drugs through music.

    Science.gov (United States)

    Mark, A

    1986-01-01

    This paper discusses a technique which uses rock music lyrics to enable adolescents to gain an understanding of dependency upon mood-altering substances. While the pervasiveness of alcohol and other drugs in society is well-known, it is surprising and instructive for adolescents to explore the close inter-relationship between drugs, rock lyrics, and their own behavior. Drug-related songs were chosen, recorded and the lyrics were transcribed. A chart, illustrating the progression of addiction, was used to demonstrate how themes in drug-related songs parallel the stages of addiction. Adolescents hear, read, and discuss the lyrics in relationship to the stages, and in the process, increase their personal understanding of drug issues such as the search for relief, increased dependence, loss of control, and physical deterioration, all stages on the addiction chart. Through guided discussion of the lyrics and issues, adolescents begin to consider alternative ways of coping with daily pressures other than withdrawal from society or aggression toward it, two types of behavior seen with increasing frequency among today's youth.

    2004-01-01

    The round table discussions of the second session of the FSC Belgium Workshop addressed the following questions: - Do local stakeholders have, internally or externally, all the expertise they need in order to address the issues raised by radioactive waste management projects? - Do institutional stakeholders have all the expertise they need to take local impacts into account? - What kinds of expert input are sought and attained by the different stakeholders? - Were any formal methods used to aid local partnerships perform technology assessments? Or other types of assessment? - How to maintain the knowledge and expertise achieved by the stakeholders? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. As in Session I, most of the round table discussion focussed specifically on the experience of the local partnerships. Many insights were shared about the nature and role of expertise in complex decision making. They are summarised below, on the basis of the feedback provided to the plenary by each round table. Some of these insights can be generalised to other contexts. All in all, a profile emerged of the local partnerships as a unique and effective tool to deal with knowledge issues in managing risk.

    The study gives a survey of the factors most frequently mentioned in the literature as factors likely to adversely affect a pregnancy. One essential aspect is the discussion of those factors that can be counted among the causes of malformations, as among others, prenatal radiation exposure. The study prepared within the framework of the research project 'Radiobiological environmental monitoring in Bavaria' is intended to serve as a basis for a retrospective and prospective evaluation of infant mortality, perinatal conditions and occurrence of malformations in Bavaria, with the principal idea of drawing up an environment - related health survey. The study therefore, in addition to ionizing radiation also takes into account other detectable risks within the ecologic context, as e.g. industrial installations, refuse incineration plants or waste dumps, or urbanity.

    Being in the moment, showing compassion, being non-judgmental, acknowledging deep emotional challenges without getting stuck: these are mindfulness characteristics important to us as teachers, yet not often included in teacher preparation. These concerns become magnified when we focus on difficult knowledge and thorny issues, like topics related to gender and race. Using a sociocultural framework, we address how mindfulness, heuristics, and other contemplative practices can be adopted to create safe, supporting, and healing spaces for such complex, often emotionally painful discussions. Participant narratives are used extensively to provide a voice to those marginalized or hurt. Drawing from these narratives and their experience in discussing thorny issues, we put forth possible solutions and interventions that can create spaces that encourage and support critical discourse through mindful practices. The development of a heuristic for discussing thorny issues whose characteristics can be adopted by interested teachers and educators to help frame and mediate this type of difficult discussion is an outcome of this research.

    2013-01-01

    Peer relationships, particularly friendships, have been theorized to contribute to how children and adolescents think about social and moral issues. The current study examined how young adolescent best friends (191 dyads; 53.4% female) reason together about multifaceted social dilemmas and how their reasoning is related to friendship quality. Mutually-recognized friendship dyads were videotaped discussing dilemmas entailing moral, social-conventional and prudential/pragmatic issues. Both dyad members completed a self-report measure of friendship quality. Dyadic data analyses guided by the Actor-Partner Interdependence Model indicated that adolescent and friend's reports of friendship qualities were related to the forms of reasoning used during discussion. Friends who both reported that they could resolve conflicts in a constructive way were more likely to use moral reasoning than friends who reported that their conflict resolution was poor or disagreed on the quality of their conflict resolution. The findings provide evidence for the important role that friendship interaction may play in adolescents’ social and moral development. PMID:23666555

  1. Panel discussion: Chemistry aspects of pet radiotracers

    1991-01-01

    A panel discussion on the radiotracer development process opened with a question regarding the role of toxicological studies in the process of obtaining a physician-sponsored Investigational New Drug (IND) for a new radiopharmaceutical. Panel members were uniformly supportive of new radiotracer development, expressing their opinions that the regulatory hurdles were there but could be overcome. Several institutions are actively working with regulatory agencies to determine just what toxicology data are relevant to new radiopharmaceutical development in the PET field. The FDA is beginning to understand that the pharmacology of PET tracer doses may be completely different from what is usually important in drug trials. The second part of the panel discussion centered on the role, if any, of the pharmaceutical companies in new radiotracer development. It was pointed out that what the radiochemist is looking for in a radiopharmaceutical is different from what these companies are searching for in a therapeutic drug. Panel and audience members responded to the question: What would a pharmaceutical company gain from collaboration with radiopharmaceutical research laboratories? Several examples were given such as providing crucial data from humans rather than animals; determining individualized drug doses to maximize the therapeutic index of a new drug regimen; and replacing the large amounts of time and money currently invested by drug companies in the radiolabeling and evaluation of metabolites of new drugs

    Full Text Available In this article we present a reflection on research conducted to define a strategic gender equality indicators system. The system was dedicated to monitoring, in a synthetic and comprehensive way, the evolution of this phenomena in the Basque Country. Firstly, on the basis of the relevant literature on the subject, we examine the problems behind the measuring of gender inequality. Secondly, the indicators system is described: its aims, its relation with the existing equality information and evaluation tools and the main features of its elaboration. Finally, we discuss in greater detail what challenges appeared and the theoretical, conceptual and methodological decisions made. We give special attention to showing how we intended to grasp, with indicators, a feminist, broad, political, transformative and context-oriented concept of gender (inequality.

    Full Text Available In modern times, various theoretical elaborations around the concept of «artifact», arose from different areas and paradigms in the social sciences and humanities. Without attempting to exhaust the multidisciplinary theoretical review, the article describes some axes of conceptual arguments and criteria for possible didactic interventions in educational practices. The concept of «literate culture» has been put in value by Roger Chartier and other authors. The notion of «cultural artifact» has been discussed by authors such as Holland and Cole. This article suggests several applications of these concepts to the educational reality, taking into account the social and technological changes, with particular emphasis on the artifactual approach of literacy by Pahl and Rowsell.

    Full Text Available The pedagogical work with mathematical modeling assumes investigate situations of reality. However, mental models formed from the contact with the experiential world are generally incompatible with the conceptual models. So David Hestenes supports the view that one of the biggest challenges of teaching and learning in science and mathematics is to coordinate conceptual models with mental models, which led to the elaboration of a didactic in mathematical modeling: Modeling Instruction. Our goal is to present a proposal for thematic modeling cycle drawn up in hestenesianos assumptions and discuss possibilities for scientific literacy. The main question was to know how to emerge indicators for scientific literacy for the proposed cycle. This is a bibliographic research in order to identify the available literature contributions on the subject and raise the possibility and challenges for the brazilian teaching science and mathematics. Preliminary results indicate that the proposed modeling cycle can develop indicators for scientific literacy of different natures.

    Full Text Available This paper presents an exploratory action research study carried out by two English as a foreign language teachers in a private, non-profit institution in Bogota, Colombia, with a group of 12 learners in a B1 English course. These students faced difficulties elaborating on their ideas when discussing issues in class. The study placed emphasis on the use of argumentation outlines and peer assessment to boost learners’ argumentative abilities. Audio-taped conversations and open-ended interviews were used to understand the impact on the pedagogical intervention. Findings revealed that argumentation outlines and peer assessment can promote learners’ awareness and ability to engage in argumentation processes. Moreover, peer assessment appears to be an essential tool for enhancing personal and collaborative learning, as well as for promoting learner reflection and agency.

    This chapter deals with the radiotherapy and cytotoxic chemotherapy of the malignant lymphomas. Included within this group are Hodgkin's disease, non-Hodgkin's lymphoma, mycosis fungoides, and chronic lymphatic leukaemia. A further section deals with the myeloproliferative disorders, including granulocytic leukaemia, polycythaemia vera, and primary thrombocythaemia. Excluded are myeloma and reticulum cell sarcoma of bone and acute leukaemia. With regard to Hodgkin's disease, the past 25 years have seen general recognition of the curative potential of radiotherapy, at least in the local stages, and, more recently, awareness of the ability to achieve long-term survival after combination chemotherapy in generalised or in recurrent disease. At the same time the importance of staging has become appreciated and the introduction of procedures such as lymphography, staging laparotomy, and computer tomography (CT) has enormously increased its reliability. Advances have not been so dramatic in the complex group of non-Hodgkins's lymphomas, but are still very real

    Health plans of the Spanish autonomous communities can incorporate sustainable development criteria in its development. There have been no analysis or proposals about development and indicators. The goal is to add a contribution to help build better health plans aimed at sustainable development and help to manage economic, social and environmental impacts of health systems criteria. We used a variation of the RAND/UCLA or modified Delphi technique method. The process consisted of a bibliographical and context matters and issues related to health and social responsibility analysis based on ISO 26000: 2010. A survey by deliberately to a selection of 70 expert members of the identified stakeholders was carried out and a discussion group was held to determine the consensus on the issues addressed in the survey sample. The research was conducted in 2015. From the literature review 33 health issues included in ISO 26000:2010 were obtained. 7 survey proved relevant high consensus, 8 relevance and average consensus and 18 with less relevance and high level of dissent. The expert group excluded 4 of the 18 subjects with less consensus. 29 issues included 33 at work, divided into 7 subjects contained in the guide ISO 26000 of social responsibility, were relevant stakeholders regarding possible inclusion in health plans. Considering the direct relationship published by ISO (International Organization for Standardization) among the issues ISO 26000 and the economic, social and environmental indicators in GRI (Global Reporting Initiative) in its G4 version, a panel with monitoring indicators related to relevant issues were elaborated.

  15. Avoiding the Theory Trap When Discussing Evolution

    Science.gov (United States)

    Morrison, David

    2006-02-01

    Public opinion polls tell us that we are losing the battle to explain the nature of evolution and its central role in science. One problem, I believe, is letting the opponents of evolution frame the discussion to our disadvantage. Framing involves the selective use of language or context to trigger responses, either support or opposition. As a prime example, we undercut our communications efforts with many nonscientists by defending the `theory of evolution.' Theory is the wrong word to use in addressing the public. In the contemporary U.S., theory means a hunch or idea that has not been established by evidence. It is thus no surprise that polls show that nearly three quarters of U.S. people think that ``evolution is commonly referred to as the theory of evolution because it has not yet been proven scientifically.'' Those who advocate adding ``only a theory'' disclaimers in textbooks know that to call evolution a theory is sufficient to undermine its acceptance.

    1983-01-01

    Memories of events which are unremarkable may pass unrecorded or may fade with the passage of time. In any situation of stress, anxiety may cloud the memory of the incident and in the case of some intensely frightening or humiliating experience such material may not be subject to voluntary conscious recall and may be repressed. A technique for uncovering certain 'forgotten' or repressed memories with the use of hypnosis is described. A similar method has been used in order to retrieve such memories in the investigation of witnesses and victims of serious crime. Nevertheless, various aspects of the overall validity of such a procedure have been called into question and for this reason the results of numerous experiments and the conclusions arrived at in many papers are discussed. It is emphasized that a rigid code of conduct be followed if hypnosis is to be used as an investigatory tool. PMID:6864721

  18. Round-table discussion on food irradiation

    International Nuclear Information System (INIS)

    1973-01-01

    The possibilities of using radiation for food preservation as a way of alleviating the food deficiency problem in a large part of the world has been studied for some 20 years. Since the idea was recognized as a viable one, scientists had to develop it along three levels: firstly, the technological problems and economic viability had to be faced; at the same time tests had to be initiated to prove the wholesomeness of the irradiated foodstuffs, and then public acceptance and confidence in the end product had to be established. Work is proceeding along these three lines and in some cases, success has been won on all fronts. In others, it is continuing. As a FLASHBACK to the situation TWO YEARS AGO, we thought it interesting to reprint excerpts from a round-table discussion at which scientists from five countries sat down to discuss the pros and cons of food irradiation. ost at the gathering was Dr. Rocco Basson, Director of Chemistry at Pelindaba, South Africa, and the man responsible for directing radiation processing in that country. With him were Dr. Lapidot, Head of the Radiation and Engineering and Processing Section of the Israel Atomic Energy Commission at Soreq; Dr. Saint-Lebe of the Radioagronomy Service, French Atomic Energy Commission, at Cadarache; Dr. Ulmann, then Director of the Food Irradiation Pilot Plant at Wageningen in Holland; and Mr. Roy Hickman, leader of the International Project in the Field of Irradiation, sponsored by the FAO, IAEA and the OECD Nuclear Energy Agency, centred at Karlsruhe in Germany.

    Full Text Available Before 9/11 WTC was an international landmark. The definition of the two high-rise buildings identity, their tourist, social, visual and economic significance, disappeared with the destruction of their materiality. As a result, the contemplative visual and unwritten discourse of the Lower Manhattan disappeared together with the architectural, urban, technological essence and also with the philosophy of stability and equilibrium of a prosperous society. At the social-mental level this event triggers a crisis in personal and collective consciences (of the American Nation but also of the Nations, and a crisis of humanity. The architectural - urban and ideas competition organized to select the best urban-social-architectural concept proved to be a difficult task. Not only it had to “fill” a particular place on earth, but it also needed to configure a philosophy of place that would ‘heal” the wounds of the local and international communities, namely the lack of security and prosperity brought on by a no longer hidden technology of aggression bringing cities and communities under threats never experienced before at times of peace. In its first part the article discusses the competition, proposals and the finalized urban project. The particular challenges related to the selection of design in the case of WTC are doubled by a certain complexity related to the institutional arrangements common to most large urban development projects. It is also clear that there is interdependency between the project governance and the project results. These aspects are discussed in the second part of the article.

    2008-07-01

    In order to collect information on the behaviour of the future GFR (Gas Fast Reactor) fuel under fast neutron irradiation, an experimental irradiation program, called 'Futurix-concepts' has been launched at the CEA. The considered concept is a composite material made of a fissile fuel embedded in an inert ceramic matrix. Fissile fuel pellets are made of UPuN or UPuC while ceramics are SiC for the carbide fuel and TiN for the nitride fuel. This paper focuses on the description of the carbide composite fabrication. The UPuC pellets are manufactured using a metallurgical powder process. Fabrication and handling of the fuels are carried out in glove boxes under a nitrogen atmosphere. Carbide fuel is synthesized by carbo-thermic reduction under vacuum of a mixture of actinide oxide and graphitic carbon up to 1550 deg. C. After ball milling, the UPuC powder is pressed to create hexagonal or spherical compacts. They are then sintered up to 1750 deg. C in order to obtain a density of 85 % of the theoretical one. The sintered pellets are inserted into an inert and tight capsule of SiC. In order to control the gap between the fuel and the matrix precisely, the pellets are abraded. The inert matrix is then filled with the pellets and the whole system is sealed by a BRASiC{sup R} process at high temperature under a helium atmosphere. Fabrication of the sample to be irradiated was done in 2006 and the irradiation began in May 2007 in the Phenix reactor. This presentation will detail and discuss the results obtained during this fabrication phase. (authors)

  4. Elaboration of the methodological referential for life cycle analysis of first generation biofuels in the French context

    International Nuclear Information System (INIS)

    2008-01-01

    This study was made under the particular context of a strong growth of biofuels market, and the implication of French and European public authorities, and certain Member States (Germany, Netherlands, UK), for the development of certification schemes for first generation biofuels. The elaboration of such schemes requires a consensus on the methodology to apply when producing Life Cycle Analysis (LCA) of biofuels. To answer this demand, the study built up the methodological referential for biofuels LCAs in order to assess the Greenhouse Gases (GHG) emissions, fossil fuels consumptions and local atmospheric pollutants emissions induced by the different biofuel production pathways. The work consisted in methodological engineering, and was accomplished thanks to the participation of all the members of the Technical Committee of the study. An initial bibliographic review on biofuels LCAs allowed the identification of the main methodological issues (listed below). For each point, the impact of the methodological choices on the biofuels environmental balances was assessed by several sensitivity analyses. The results of these analyses were taken into account for the elaboration of the recommendations: - Consideration of the environmental burdens associated with buildings, equipments and their maintenance - Quantification of nitrous oxide (N 2 O) emissions from fields - Impact of the Land Use Change (LUC) - Allocation method for the distribution of the environmental impacts of biofuel production pathways between the different products and coproducts generated. Within the framework of this study, we made no distinction in terms of methodological approach between GHG emissions and local pollutants emissions. This results from the fact that the methodological issues cover all the environmental burdens and do not require specific approaches. This executive summary presents the methodological aspects related to biofuels LCAs. The complete report of the study presents in addition

  5. Development, improvement and calibration of neutronic reaction rates measurements: elaboration of a standard techniques basis

    International Nuclear Information System (INIS)

    Hudelot, J.P.

    1998-06-01

    In order to improve and to validate the neutronics calculation schemes, perfecting integral measurements of neutronics parameters is necessary. This thesis focuses on the conception, the improvement and the development of neutronics reaction rates measurements, and aims at building a base of standard techniques. Two subjects are discussed. The first one deals with direct measurements by fission chambers. A short presentation of the different usual techniques is given. Then, those last ones are applied through the example of doubling time measurements on the EOLE facility during the MISTRAL 1 experimental programme. Two calibration devices of fission chambers are developed: a thermal column located in the central part of the MINERVE facility, and a calibration cell using a pulsed high flux neutron generator and based on the discrimination of the energy of the neutrons with a time-of-flight method. This second device will soon allow to measure the mass of fission chambers with a precision of about 1 %. Finally, the necessity of those calibrations will be shown through spectral indices measurements in core MISTRAL 1 (UO 2 ) and MISTRAL 2 (MOX) of the EOLE facility. In each case, the associated calculation schemes, performed using the Monte Carlo MCNP code with the ENDF-BV library, will be validated. Concerning the second one, the goal is to develop a method for measuring the modified conversion ratio of 238 U (defined as the ratio of 238 U capture rate to total fission rate) by gamma-ray spectrometry of fuel rods. Within the framework of the MISTRAL 1 and MISTRAL 2 programmes, the measurement device, the experimental results and the spectrometer calibration are described. Furthermore, the MCNP calculations of neutron self-shielding and gamma self-absorption are validated. It is finally shown that measurement uncertainties are better than 1 %. The extension of this technique to future modified conversion ratio measurements for 242 Pu (on MOX rods) and 232 Th (on

    This study aims to examine competing explanations of the relationship between religious and political ideology commitment with posttraumatic growth. Subjects were Israeli youth who were exposed to terror (n = 2,999) aged 13-15. Measures included: posttraumatic growth inventory, religious orientation, ideological commitment, objective and subjective exposure to terror. Both religiosity and political ideology mediated the effects of exposure and fear on growth. Political ideology but not religiosity, had a moderating effect, such that subjective fear was positively associated with growth only among those with stronger ideologies. Results support the contention of Terror Management Theory that cultural beliefs have beneficial effects on well being in the face of adversity and emphasize the role of cultural world as effecting growth, beyond trauma.

  8. Potential for nuclear terrorism: a discussion

    Because there has never been an incident of nuclear terrorism, the author is reduced to informed speculation. The past cannot be used to extrapolate into the future. For terrorists as for nations, the domain of nuclear attack represents are unprecedented quantum leap, one that groups think carefully about. Terrorists will consider many factors, including the public climate, because they are not psychotics operating in a vacuum (though groups may include psychotic individuals). Rather, they are people involved in a reciprocal political and psychological relationship with the rest of the world. In reaching some assessment of the potential for nuclear terrorism, there is an immense number of variables to deal with, beginning with the many types of terrorists and terrorism, including nuclear. They can, however, look at individual terrorist groups - a their compositions, capabilities, motivations, and modus operandi - and reach some conclusions. The author first looks at the possible forms nuclear terrorism might take and at the severity of the consequences. A strict distinction must be made between nuclear terrorism where nuclear things are the means (for example, a nuclear device) and nuclear terrorism where nuclear things are the target (for example, nuclear power stations), or where they are both such as a nuclear weapon thrown at a nuclear power station. 2 tables

  9. [Discussion on twirling reinforcing-reducing method].

    2014-01-01

    The essence of twirling reinforcing-reducing method is discussed to provide theoretical guidance for clinical application of reinforcing-reducing method. Through retrospection on historical literature of twirling reinforcing-reducing method, records and explanatory notes are thoroughly explored. Several existing opinions are analyzed and explained for instance twirling method has connection with circulation direction of channels; twirling method is subdivided into right and left, male and female, hand and foot; twriling method is related to quantity of stimulus and operation time; twriling method belongs to spiral motion and so on. As a result, it is found that the key of twirling reinforcing-reducing method is the posture of needle-holding hand that defines three-dimensional motion. If twirling method is subdivided into right and left, male and female, hand and foot and so on, steric effects of lifting-thrusting movement that come along with twirling method could be ignored at the same time. It is that the essence of twirling reinforcing-reducing method is close to the principle of lifting-thrusting reinforcing-reducing method, enriching effect with slow insertion and fast withdrawal of needle while reducing effect with fast insertion and slow withdrawal, which is recorded in Miraculous Pivot: Nine needle and Twelve Yuan. With this principle as guide, manipulation could be avoided to become a mere formality and illusory metaphysics during clinical application of twirling reinforcing-reducing method.

    Full Text Available The research programme on vicarious learning, part of which we report in this paper, has been aimed at exploring the idea that learning can be facilitated by providing learners with access to the experiences of other learners. We use Bandura's term vicarious learning to describe this (Bandura, 1986, and we believe it to be a paradigm that offers particular promise when seen as an innovative way of exploiting recent technical advances in multimedia and distance learning technologies. It offers the prospect of a real alternative to the building of intelligent tutors (which directly address the problem of allowing learners access to dialogue, but which have proved largely intractable in practice or to the direct support of live dialogues (which do not offer a solution to the problem of providing 'live' tutors - unless they are between peer learners. In the research reported here our main objectives were to develop techniques to facilitate learners' access to, especially, dialogues and discussions which have arisen when other learners were faced with similar issues or problems in understanding the material. This required us to investigate means of indexing and retrieving appropriate dialogues and build on these to create an advanced prototype system for use in educational settings.

  11. Discussion on posting and labeling for radioprotection

    Suzuki, Fabio F.

    2009-01-01

    The radioprotection aims the protection of people against exposure to ionizing radiation or radioactive substances as well as the safety of radiation sources. As ionizing radiation is not perceived by human senses, the warning signs and labels on radiation sources and the safety posters in controlled and supervised areas have an important role to keep the doses and risks as low as reasonably achievable, to prevent radiological accidents and to mitigate their consequences. In Brazil, several technical regulations require such safety labels and posters, however, despite their importance, there is quite few guidance about their format or contents. In this paper the posting and labeling requirements for radiological control existing in Brazilian technical regulations are discussed, confronting them with national, foreign and international technical standards and by drawing up a parallel with requirements of technical regulations from other countries. Changes are suggested in some parts of the national regulations, to prevent some differences in the current guidance, allowing the optimization of posting and labeling programs of radiological facilities.

    2017-06-01

    Astronomy courses that are either hybrid in nature or offered in a completely online format are becoming more common at colleges and universities. In particular, faculty members at small colleges are being encouraged to develop courses that can be taught online in order to give students increased flexibility in scheduling classes and reach a separate population of learners. For instructors accustomed to teaching students in person using plenty of interaction, making the switch to teaching even one online course a year can be challenging. However, some topics are developing so rapidly (exoplanets) that it is difficult to imagine having students rely on a standard textbook at all, and the use of online resources become essential. Here, we describe methods used to promote discussion, evaluate its content and effectively incorporate the use of recently released articles in order to keep students engaged. We present efforts to produce a lively classroom atmosphere centered on recent advances and several debated topics. Lastly, we report on successes, challenges and plans for improving online courses in the future.

    The grand unified theories (GUT) of the simple Lie groups including extra Z bosons are discussed. Under authors's hypothesis there are only SU 5+m SO 6+4n and E 6 groups. The general discussion of SU 5+m is given, then the SU 6 and SU 7 are considered. In SU 6 the 15+6 * +6 * fermion representations are used, which are not same as others in fermion content, Yukawa coupling and broken scales. A conception of clans of particles, which are not families, is suggested. These clans consist of extra Z bosons and the corresponding fermions of the scale. The all of fermions in the clans are down quarks except for the standard model which consists of Z bosons and 15 fermions, therefore, the spectrum of the hadrons which are composed of these down quarks are different from hadrons at present

    Incidence and prevalence studies of neurological disorders play an extremely important role in hypothesis-generation, assessing the burden of disease and planning of health services. However, the assessment of disease estimates is hindered by the poor quality of reporting for such studies. We developed the Standards of Reporting of Neurological Disorders (STROND) guideline in order to improve the quality of reporting of neurological disorders from which prevalence, incidence, and outcomes can be extracted for greater generalisability. The guideline was developed using a 3-round Delphi technique in order to identify the 'basic minimum items' important for reporting, as well as some additional 'ideal reporting items.' An e-consultation process was then used in order to gauge opinion by external neuroepidemiological experts on the appropriateness of the items included in the checklist. The resultant 15 items checklist and accompanying recommendations were developed using a similar process and structured in a similar manner to the Strengthening of the Reporting of Observational Studies in Epidemiology checklist for ease of use. This paper presents the STROND checklist with an explanation and elaboration for each item, as well as examples of good reporting from the neuroepidemiological literature. The introduction and use of the STROND checklist should lead to more consistent, transparent and contextualised reporting of descriptive neuroepidemiological studies that should facilitate international comparisons, and lead to more accessible information for multiple stakeholders, ultimately supporting better healthcare decisions for neurological disorders.

    The objective of this research study is to analyse, through a detailed study of microstructure, the mechanisms of solidification in Fe 75 Al 25 et Fe 75-x Al 25 B x(0,05-1) (wt pc) alloys elaborated by plane cast melt spinning. The author notably highlights the influence of manufacturing parameters on tape final microstructure. After a bibliographical review on fast solidification mechanism in crystalline materials, and a bibliographical synthesis on the plan cast melt spinning process, the author describes precisely the elaboration phase of Fe Al and Fe Al B tapes. Surface condition and geometry of tapes are characterized and analysed with respect to process parameters. Cooling rates and thermal transfer coefficients on the wheel and in the process atmosphere are determined by means of pyrometric measurements performed at the tape surface during the process. A thermal modelling code is then developed to simulate the cooling and solidification of FeAl 25 (wt pc). Microstructure characterizations of tapes are then reported, and the different noticed microstructures are discussed and analysed by using the thermal model and a study of annealed products [fr

    A job-exposure matrix (JEM) for inhalable aerosols, aromatic amines, and cyclohexane soluble matter (CSM) was elaborated based on measurements collected routinely between 1981 and 1996. The data were grouped based on similarities in exposure levels and time trends in different departments, and were analyzed using smoothing splines and mixed effects models. Although higher than in western European countries, inhalable aerosol exposure decreased after changes in production volume and implementation of exposure reduction measures in mid-1980s. Aromatic amines concentrations first increased following the factory's production volume, but subsequently decreased in more recent years. CSM concentrations were uniformly distributed between departments. This JEM provides an overview of historical exposure levels in a large Polish rubber factory and will enable estimation of lifetime exposure for individual workers in a Polish rubber workers cohort and further investigation of the associations between specific exposures and cancer risk.

    As climate negotiations reopen on November, 6 at COP23 in Bonn to advance the concrete implementation of the different provisions of the Paris Agreement, this paper aims to take stock of the open questions of Article 15. They concern the role of the Committee responsible for 'facilitating compliance and promoting implementation'. First, the paper outlines what was already decided in Paris in 2015 as well as the issues still to be resolved by the end of 2018. These include the scope of its application, the means to initiate Article 15 as well as the outcomes that the committee can produce and the tools it should have at its disposal. Keeping in mind Paris Agreement's uniqueness and its philosophy, the author attempts to identify the added value of Article 15's mechanism and suggests ways to address the respective expectations and concerns of Parties, in order to progress towards a consensual resolution that is acceptable to a large number of Parties

    As the genetic counseling field evolves, a comprehensive model of practice is critical. The Reciprocal-Engagement Model (REM) consists of 5 tenets and 17 goals. Lacking in the REM, however, are well-articulated counselor strategies and behaviors. The purpose of the present study was to further elaborate and provide supporting evidence for the REM by identifying and mapping genetic counseling strategies to the REM goals. A secondary, qualitative analysis was conducted on data from two prior studies: 1) focus group results of genetic counseling outcomes (Redlinger-Grosse et al., Journal of Genetic Counseling, 2015); and 2) genetic counselors' examples of successful and unsuccessful genetic counseling sessions (Geiser et al. 2009). Using directed content analysis, 337 unique strategies were extracted from focus group data. A Q-sort of the 337 strategies yielded 15 broader strategy domains that were then mapped to the successful and unsuccessful session examples. Differing prevalence of strategy domains identified in successful sessions versus the prevalence of domains identified as lacking in unsuccessful sessions provide further support for the REM goals. The most prevalent domains for successful sessions were Information Giving and Use Psychosocial Skills and Strategies; and for unsuccessful sessions, Information Giving and Establish Working Alliance. Identified strategies support the REM's reciprocal nature, especially with regard to addressing patients' informational and psychosocial needs. Patients' contributions to success (or lack thereof) of sessions was also noted, supporting a REM tenet that individual characteristics and the counselor-patient relationship are central to processes and outcomes. The elaborated REM could be used as a framework for certain graduate curricular objectives, and REM components could also inform process and outcomes research studies to document and further characterize genetic counselor strategies.

    The snail (Helix aspersa mueller) secretion or its filtrating is an emerging raw material utilized to elaborate different cosmetics products in Chile. This secretion has properties such as regeneration and healing of tissues, elimination of spots in the body, among others. All of them are associated to some of its own components, like the glycolic acid and alantoine. However, working with the secretion has not been free of complications nor sanitary difficulties due to the great manipulation to which it is exposed to, making it vulnerable to microbiological contaminations and causing it not to qualify according to the sanitary criteria stated by cosmetics laboratories, resulting in the material loss for the producer. The ionizing energy from radioactive sources appears to be an efficient alternative to control and reduce the microorganisms of these raw materials destined to the cosmetology industry. The proposed study to determine irradiation benefits required cooled secretion samples obtained from a snail hatchery. The samples were irradiated with doses of 3.0, 5.0 and 7.0 kGy, in order to verify the microbiological reduction and to establish a reduction probability of chemical components that are important in cosmetic products. Our results have allowed to determine that doses of 5.0 and 7.0 kGy reduce the total count of mesophyles in 4 and 5 logarithmic cycles, respectively, These reduction values allow the secretion to be accepted by the laboratories dedicated to process it and elaborate the cosmetic products. On the other hand, to evaluate the effects of chemical components, like total proteins, alantoine and glycolic acid, samples irradiated were used with doses of 7.0 and 10 kGy. The result values from the chemical analysis were not affected by the irradiation and these were similar to the ones which were not irradiate.

  6. Such stuff as dreams are made on? Elaborative encoding, the ancient art of memory, and the hippocampus.

    Science.gov (United States)

    Llewellyn, Sue

    2013-12-01

    This article argues that rapid eye movement (REM) dreaming is elaborative encoding for episodic memories. Elaborative encoding in REM can, at least partially, be understood through ancient art of memory (AAOM) principles: visualization, bizarre association, organization, narration, embodiment, and location. These principles render recent memories more distinctive through novel and meaningful association with emotionally salient, remote memories. The AAOM optimizes memory performance, suggesting that its principles may predict aspects of how episodic memory is configured in the brain. Integration and segregation are fundamental organizing principles in the cerebral cortex. Episodic memory networks interconnect profusely within the cortex, creating omnidirectional "landmark" junctions. Memories may be integrated at junctions but segregated along connecting network paths that meet at junctions. Episodic junctions may be instantiated during non-rapid eye movement (NREM) sleep after hippocampal associational function during REM dreams. Hippocampal association involves relating, binding, and integrating episodic memories into a mnemonic compositional whole. This often bizarre, composite image has not been present to the senses; it is not "real" because it hyperassociates several memories. During REM sleep, on the phenomenological level, this composite image is experienced as a dream scene. A dream scene may be instantiated as omnidirectional neocortical junction and retained by the hippocampus as an index. On episodic memory retrieval, an external stimulus (or an internal representation) is matched by the hippocampus against its indices. One or more indices then reference the relevant neocortical junctions from which episodic memories can be retrieved. Episodic junctions reach a processing (rather than conscious) level during normal wake to enable retrieval. If this hypothesis is correct, the stuff of dreams is the stuff of memory.

    Full Text Available The task of identifying named entities from the discussion texts in Web forums faces the challenge of noisy names. As the names are often misspelled or abbreviated, the conventional techniques have failed to detect the noisy names properly. In this paper we propose a global context based framework for handling the noisy names. The framework is tested on a named entity recognition system designed to identify the names from the discussion texts in a homeopathy diagnosis discussion forum. The proposed global context-based framework is found to be effective in improving the accuracy of the named entity recognition system.

  9. A clinically focused discussion of luting materials.

    Hill, E E; Lott, J

    2011-06-01

    A luting agent's primary function is to fill the minute void between an indirect restoration (definitive or provisional) and tooth (or implant abutment) and mechanically lock the restoration in place to prevent dislodgement during function. The purpose of this paper is to provide a clinically focused discussion on the broad spectrum of luting materials currently available to help the general practitioner make appropriate choices. Resins are typically formulated for a specific function or restoration and offer strength, aesthetics, flexible working times, and very low solubility yet are technique sensitive, expensive and often hard to clean-up. Glass-ionomers offer good strength and optical properties plus the potential for fluoride release/recharge but may have short working times, are sensitive to moisture or dehydration early on, and take time to fully set. Resin-modified glass-ionomers are hybrid, dual-phase materials which are manipulated like glass-ionomer but set quicker and are stronger. Zinc phosphate cement, used successfully for over a century to lute well-fitting metal and metal-ceramic definitive restorations, is a very inexpensive, rigid material which displays very high early compressive strength yet acidity and solubility can be problems. Polycarboxylate cement (a hybrid of zinc phosphate) has lower compressive strength but high tensile strength and may be less injurious to the pulp. Zinc oxide eugenol and zinc oxide non-eugenol cements typically have good sealing abilities but their relatively low compressive and tensile strengths, inherent brittleness, and high solubility limit usage to provisional restorations or implant supported crowns.

    Full Text Available This study focuses on the characterization of graphocentrism in microculture. We aim to describe, based on literacy studies, the presence of written language in the life of socially and historically situated subjects, thematizing the axiological capital of less favored socioeconomic contexts. Subjects are children undergoing schooling process, living in a district of Florianópolis, Santa Catarina, Brazil. Discussions on the theme are based on Barton (1994, Barton, Hamilton and Ivanic (2000, Heath (1982, and Street (1994, 2003. Looking at literacy from a sociocultural perspective implies understanding that subjects deal with written language in their daily life in different ways. It seems that school tends to teach subject matters defined beforehand, and this hampers the dialog with different social practices played by students who come from family environments with different schooling levels. This study is inserted in a project whose focus is the defense of a more sensible look of school concerning the different realities which constitute school itself, regarding the teaching of written language. The present research aims to answer the following questions: How can we configure the microculture (family, school, church, neighborhood – more or less graphocentric – where children attending 1st to 5th grade live, in an economically less privileged community of Florianópolis? How can we delineate the axiological capital regarding the mastering of written language by those children? What literacy events are more recurrent within that microculture? The data were collected by means of interviews, observations and field annotations, focusing on the visible elements of literacy events, similarly to what has been done by Hamiton (2000, such as participants, environments, artifacts, and activities. On the hand, the non-visible constituents of literacy practices, such as hidden participants, domain, resources, and routines, were observed during

  11. Water, food, and population -- a panel discussion.

    This paper summarizes a conference panel discussion among parliamentarians and researchers on water and food supplies and population growth in Asia. The Western Samoa legislator urged delegates to be aware of human development that was no more than the promotion of values associated with a market economy. Samoans increased their per capita caloric consumption. The food supply is provided locally, and 90% of exports are food products. Food security would be jeopardized by a fivefold increase in population. Samoan human development indicators were relatively good for a developing country. However, the country was still ranked as a low-income, food-deficit country. The Pakistani delegate explained that Pakistan's agriculture used the largest, continuous irrigation system in the world. However, the system operated inefficiently. There was concern that future high population growth would jeopardize food security. Another barrier was institutional mismanagement of irrigation and reliance on imports for staple items. Agricultural productivity must increase to meet the increased needs of continued population growth. All available land is currently under cultivation. Future strategies will necessitate international cooperation and innovative and environmentally sound technology. Professor Xuan remarked that increased population growth and rising demand, decreased water quality, and changing consumption patterns were a threat to water supplies. Sustainable increases in food production would entail better water management: reforestation to reduce and prevent water runoff, better technological exploitation of rain water, and more efficient use of irrigation systems. Better international financing schemes were needed for support of these policy changes. Professor Ness suggested free markets in water in order to price water at actual rates of consumption. Polluters should pay. Water management was also threatened by global warming.

  12. Appearance and elaboration of the ethylene receptor family during land plant evolution.

    2015-03-01

    Ethylene is perceived following binding to endoplasmic reticulum-localized receptors, which in Arabidopsis thaliana, include ETR1, ERS1, EIN4, ETR2, and ERS2. These receptors fall into two subfamilies based on conservation of features within their histidine kinase domain. Subfamily 1 contains ETR1 and ERS1 whereas subfamily 2 contains EIN4, ETR2, and ERS2. Because ethylene receptors are found only in plants, this raises questions of when each receptor evolved. Here it is shown that subfamily 1 receptors encoded by a multigene family are present in all charophytes examined, these being most homologous to ETR1 based on their evolutionary relationship as well as containing histidine kinase and receiver domains. In charophytes and Physcomitrella patens, one or more gene family members contain the intron characteristic of subfamily 2 genes, indicating the first step in subfamily 2 receptor evolution. ERS1 homologs appear in basal angiosperm species after Amborella trichopoda and, in some early and basal angiosperm species and monocots in general, it is the only subfamily 1 receptor present. Distinct EIN4 and ETR2 homologs appear only in core eudicots and ERS2 homologs appear only in the Brassicaceae, suggesting it is the most recent receptor to evolve. These findings show that a subfamily 1 receptor had evolved and a subfamily 2 receptor had begun to evolve in plants prior to the colonization of land and only these two existed up to the appearance of the first basal angiosperm. The appearance of ERS2 in the Brassicaceae suggests ongoing evolution of the ethylene receptor family.

    Full Text Available Flow is a construct imported in marketing research from social sciences in order to examine consumer behavior in the online medium. The construct describes a state of deep involvement in a challenging activity, most frequently characterized by high levels of enjoyment, control and concentration. Researchers found that the degree to which online experience is challenging can be defined, measured, and related well to important marketing variables. As shown by our extensive literature review, flow measurements include antecedents, dimensions and consequences of flow. The present paper represents a detailed description of the construct`s operationalization in the context of online information search. In this respect, our main goal is to produce a basic instrument to evaluate the flow experience of online search, in order to capitalize on the premises of an interactive, complex informational medium – the World Wide Web – and on the consequence of an exploratory informational behavior of users. The instrument is conceived to offer a primal possibility to collect data. The composition, source and significance of the 11 scales used to measure the multiple factors of the flow experience during online search are detailed in this study with the aim to ensure the compliance with scientific rigors and to facilitate correct reports of data related to the reliability and validity of measurements. For further research, we propose factor analysis to test the resulted instrument and to ensure that the measures employed are psychometrically sound. Factor analysis refers to a wide range of statistic techniques used to represent a set of variables in concordance with a reduced number of hypothetical variables called factors. Factorial analysis is used to solve two types of problems: reducing the number of variables to increase data processing speed and identifying hidden patterns in the existent data relations. However, we expect our scales to perform

    Being the third fastest-growing app category behind games and utilities, mHealth apps are changing the healthcare model, as medicine today involves the data they compile and analyse, information known as Big Data. However, the majority of apps are lacking in security when gathering and dealing with the information, which becomes a serious problem. This article presents a guide regarding security solution, intended to be of great use for developers of mHealth apps. In August 2015 current mobile health apps were sought out in virtual stores such as Android Google Play, Apple iTunes App Store etc., in order to classify them in terms of usefulness. After this search, the most widespread weaknesses in the field of security in the development of these mobile apps were examined, based on sources such as the "OWASP Mobile Security Project, the initiative recently launched by the Office of Civil Rights (OCR), and other articles of scientific interest. An informative, elemental guide has been created for the development of mHealth apps. It includes information about elements of security and its implementation on different levels for all types of mobile health apps based on the data that each app manipulates, the associated calculated risk as a result of the likelihood of occurrence and the threat level resulting from its vulnerabilities - high level (apps for monitoring, diagnosis, treatment and care) from 6 ≤ 9, medium level (calculator, localizer and alarm) from 3 ≤ 6 and low level (informative and educational apps) from 0 ≤ 3. The guide aims to guarantee and facilitate security measures in the development of mobile health applications by programmers unconnected to the ITC and professional health areas.

    Detection for space application is very demanding on the IR detector: all wavelengths, from visible-NIR (2- 3um cutoff) to LWIR (10-12.5um cutoff), even sometimes VLWIR (15um cutoff) may be of interest. Moreover, various scenarii are usually considered. Some are imaging applications where the focal plane array (FPA) is used as an optical element to sense an image. However, the FPA may also be used in spectrometric applications where light is triggered on the different pixels depending on its wavelength. In some cases, star pointing is another use of FPAs where the retina is used to sense the position of the satellite. In all those configurations, we might distinguish several categories of applications: • low flux applications where the FPA is staring at space and the detection occurs with only a few number of photons. • high flux applications where the FPA is usually staring at the earth. In this case, the black body emission of the earth and its atmosphere ensures usually a large number of photons to perform the detection. Those two different categories are highly dimensioning for the detector as it usually determines the level of dark current and quantum efficiency (QE) requirements. Indeed, high detection performance usually requires a large number of integrated photons such that high QE is needed for low flux applications, in order to limit the integration time as much as possible. Moreover, dark current requirement is also directly linked to the expected incoming flux, in order to limit as much as possible the SNR degradation due to dark charges vs photocharges. Note that in most cases, this dark current is highly depending on operating temperature which dominates detector consumption. A classical way to mitigate dark current is to cool down the detector to very low temperatures. This paper won't discuss the need for wavefront sensing where the number of detected photons is low because of a very narrow integration window. Rigorously, this kind of

    International Nuclear Information System (INIS)

    2005-09-01

    This report addressed the need for updated cost allocation studies filed by local electricity distribution companies because they ensure that distribution rates for each customer class remain just and reasonable. According to the 2001 Electricity Distribution Rate Handbook, the Ontario Energy Board requires new cost allocation studies before implementing any future incentive regulation plans. A review of cost allocations allows the Board to consider the need for adjustments to the current share of distribution costs paid by different classes of ratepayers. This report included 14 sections to facilitate consultations with stakeholders on financial information requirements for cost allocation; directly assignable costs; functionalization; categorization; allocation methods; allocation of other costs; load data requirements; cost allocation implementation issues; addition of new rate class and rate design for scattered unmetered loads; addition of new rate class for larger users; rates to charge embedded distributors; treatment of the rate sub-classification identified as time-of-use; and, rate design implementation issues. 1 fig., 7 appendices

    Designing a new approach for learning gross anatomy to improve students' motivation to study anatomy and to enable them to learn independently through case discussion. The study included newly registered students in the first academic year. The total number of students was 165, who were divided by alphabetical order into 15 groups of 11 students. Each group was led by one faculty member and each faculty member lead 3 groups. Each group met twice a week for 2 weeks to discuss one case related to the upper limb anatomy. Students took pre- and posttests and completed an opinion questionnaire about the case discussions. The pretest score shows that 20% of the students received grades of 60% or above and that 80% received grades less than 60%. The posttest showed that 45% of the students received grades of 60% or above and that 55% received grades less than 60%. There was a significant difference between the pre- and posttest for grades 60% (P = 0.0023). In addition, 17% of students achieved the same results (less than 60%) in both the pre- and posttests. The questionnaire revealed that all students stated that the discussion method was useful in their learning process, helped them to increase their motivation to study anatomy (85%), know the usefulness of studying anatomy (84%), and understand the problems (91%). The implementation of the case discussion in teaching anatomy can increase the students' understanding and motivate them to learn.

    [Joint Press Release by the Government of the Republic of Chile and the European Southern Observatory. The text is issued simultaneously in Santiago de Chile (in Spanish) and at the ESO Headquarters in Garching (in English).] Today, Tuesday, 18 April 1995, at the ESO Headquarters in Garching (Germany), Mr. Roberto Cifuentes, Plenipotentiary Ambassador representing the Government of the Republic of Chile, and the Director General of the European Southern Observatory, Professor Riccardo Giacconi, have signed a Supplementary, Interpretative and Amending Agreement to the Convention of 6 November 1963 which governs the relations between Chile and this International Organisation. This Agreement which in practice signifies a widening and strengthening of the cooperative relations between the Organisation and the Chilean scientific community will hereafter be submitted for ratification by the National Congress of the Republic of Chile (the Parliament) and by the ESO Council. According to the Agreement signed today, Chilean astronomers will have privileged access within up to 10 percent observing time on all present and future ESO telescopes in Chile. Moreover, ESO accepts to incorporate into its labour regulations for Chilean personnel concepts like freedom of association and collective bargaining. This signing of the Supplementary, Interpretative and Amending Agreement to the original Convention of 1963 follows after months of constructive dialogue between the parties. It constitutes an important step towards a solution of some of the pending points on the current agenda for discussions between the Government of Chile and ESO. Among the issues still pending, ESO has informed the Government of Chile that respect for its immunities by the Chilean State is of vital importance for the continuation of the construction of the world's largest telescope at Paranal, as well as the continued presence of the Organisation in Chile.

    1992-01-01

    The panelists convened to: (1) identify and evaluate the role which LNG is likely to play in the changing energy scene; (2) to examine the future supply and demand structure of the LNG trade; (3) to discover the key obstacles to continued growth in LNG trade; and (4) to find solutions to these problems. The panelists identified and outlined growing opportunities for LNG utilization in Asia during the next two decades. They shared the opinion that the structure of the supply and demand balance for LNG in Asia will shift during the next decade, providing considerable room for new projects. The key obstacles to continued growth in LNG trade are the lack of: long-distance transmission networks and an efficient competitive market pricing mechanism for LNG in the Asian region. The major importers in the region are keen on developing a range of new long-term supply alternatives, not simply within the Asia-Pacific region, but also from a wider perspective. These alternatives include: financing the expansion of production from existing facilities, development of new fields, and construction of long-distance pipelines

  4. Can warming particles enter global climate discussions?

    'Soot' or 'black carbon', which comes from incomplete combustion, absorbs light and warms the atmosphere. Although there have been repeated suggestions that reduction of black carbon could be a viable part of decreasing global warming, it has not yet been considered when choosing actions to reduce climatic impact. In this paper, I examine four conceptual barriers to the consideration of aerosols in global agreements. I conclude that some of the major objections to considering aerosols under hemispheric or global agreements are illusory because: (1) a few major sources will be addressed by local regulations, but the remainder may not be addressed by traditional air quality management; (2) climate forcing by carbon particles is not limited to 'hot spots'-about 90% of it occurs at relatively low concentrations; (3) while aerosol science is complex, the most salient characteristics of aerosol behavior can be condensed into tractable metrics including, but not limited to, the global warming potential; (4) despite scientific uncertainties, reducing all aerosols from major sources of black carbon will reduce direct climate warming with a very high probability. This change in climate forcing accounts for at least 25% of the accompanying CO 2 forcing with significant probability (25% for modern diesel engines, 90% for superemitting diesels, and 55% for cooking with biofuels). Thus, this fraction of radiative forcing should not be ignored

    A first report is a contribution to the elaboration of a plan aiming at the substitution of fossil energies, at the development of heat deliveries, while maintaining network economic profitability. Such a plan is based on the connection of buildings, the renovation, extension and interconnection of existing networks, and the creation of new heat networks. The study addressed technical, urban, financial, judicial and cartographic aspects. Public statistical data have been used and interviews of actors (network funders, representatives of delegating authorities, social landlords, administrations, and technical professions) have been performed. A guide of good practices is proposed regarding contract reviewing conditions, possibilities of revision of subscribed power. Prospective issues are discussed: strategic stakes and deposits, actions paths and tools, strategy and action plan. Appendices address methodologies, organisation of the geographical information system, judicial aspect with the circular of 1982, financial data and aspects. Then, a set of reports more precisely presents various aspects addressed as a contribution for the study of heat networks in Ile-de-France: the judicial aspect (present status, guide of good judicial practices), the economic aspect (present status of sale prices and costs, analysis of financing, of revision formula), and an assessment of urban heating development (context, technical aspect, analysis of the geographical information system)

    Theoretical rationality as defined in Expected Utility Theory and amended with other considerations gives a good basis for decision making. One should however always keep in mind that practical rationality often is far more complicated. People use their everyday experience when placed before new problems and this may lead to apparently irrational choices which on a closer scrutiny may be completely rational. Theories in human decision making unfortunately becomes untestable, firstly because a theory taking all considerations into account would be to complex to be practical and secondly because the data needed to test the theory cannot be collected. The benefit of EUT is that it is simple and straightforward as compared with competing theories. In the natural sciences rationality is often seen simply as a problem of optimisation. This view is practical, but it has to include also psychological and sociological considerations. The apparent controversy between natural and behavioural sciences could at least in principle be resolved by a better understanding of the complexity of human rationality. The human mind does not work in isolation, but it is adapted to a social community and a continuously changing environment. Understanding all components of human rationality is a challenge which cannot be solved on a short term basis. An important part of human rationality is connected to the intricate balance between individual and societal utility. The human mind has over thousands of years learnt to resolve that balance, but in the modern society there are decisions which may not be solvable with an intuitive approach and a strategy of trial and error. For these decisions more solid theories of rationality will be needed. EUT can in spite of its dismerits be used as the backbone for such a theory, but it has to be extended with better explanations of both individual and social rationality.

    The global burden of cancer is growing rapidly with an estimated 15 million new cases per year worldwide in 2015, growing to 19 million by 2025 and 24 million by 2035. The largest component of this growth will occur in low-to-middle income countries (LMICs). About half of these cases will require radiation treatment. The gap for available cancer treatment, including radiation therapy, between high-income countries (HICs) and LMICs is enormous. Accurate data and quantitative models to project the needs and the benefits of cancer treatment are a critical first step in closing the large cancer divide between LMICs and HICs. In this context, the Union for International Cancer Control (UICC) has developed a Global Task Force on Radiotherapy for Cancer Control (GTFRCC) with a charge to answer the question as to what it will take to close the gap between what exists today and reasonable access to radiation therapy globally by 2035 and what the potential clinical and economic benefits are for doing this. The Task Force has determined the projections of cancer incidence and the infrastructure required to provide access to radiation therapy globally. Furthermore it has shown that appropriate investment not only yields improved clinical outcomes for millions of patients but that it also provides an overall economic gain throughout all the income settings where this investment is made. This symposium will summarize the facets associated with this global cancer challenge by reviewing the cancer burden, looking at the requirements for radiation therapy, reviewing the benefits of providing such therapy both from a clinical and economic perspective and finally by looking at what approaches can be used to aid in the alleviation of this global cancer challenge. The speakers are world renowned experts in global public health issues (R. Atun), medical physics (D. Jaffray) and radiation oncology (N. Coleman).

    2016-01-01

    Full Text Available The article considers the elaboration of the problem of optimal algorithm synthesis of complex signal processing of satel- lite GLONASS/GPS systems navigation relayed from the Board of the upper-air radiosonde and the output data upper-air radar to determine the spatial coordinates of upper-air radiosonde. The upper-air sounding is performed with the help of technical means of radio sounding system of atmosphere, including the upper-air radiosonde, manufactured in free flight, and ground supporting equipment, which includes devices for signal processing of upper-air radiosonde and preparation of the operational upper-air mes- sages. The peculiarity of atmosphere radio sounding of domestic system is the measurement with method of radar slant range to upper-air radiosonde, the viewing angles of the antenna upper-air radar to determine azimuth and elevation of upper-air radiosonde. The disadvantage of the radar method of radiosonde support is the relatively low accuracy of determining the coordinates of the radiosonde and the possible disruption of automatic tracking in angular coordinates. Satellite navigation system based on the mi- crowave sensors has clear advantages in terms of efficiency, size, mobility, and use on mobile objects, however, with significant drawbacks associated primarily with the geometric factor and the error propagation of the navigation signal. The article presents a mathematical model useful incoherent GLONASS/GPS signals, relayed by the upper-air radiosonde, and interference on the input receiver ground point for complex information processing, and mathematical models of output data in upper-air radars.

  12. Discussion paper : offshore wind facilities renewable energy approval requirements

    International Nuclear Information System (INIS)

    2010-06-01

    This paper discussed a proposed shoreline exclusion zone for offshore wind projects in Ontario. Considerations relevant to offshore wind projects and the protection of human health, cultural heritage, and the environment were also discussed. The paper was prepared in order to provide greater clarity to renewable energy developers and to Ontario residents about the offshore wind policy that is currently being considered by the Ontario Government. Feedback received from the discussion paper will be used to propose policy and associated regulatory amendments. A 5 km shoreline exclusion zone for all offshore wind facilities was proposed. Some projects may be required to be located beyond the proposed exclusion zone. Proposed developments within the exclusion zone must meet all applicable requirements, including those related to cultural and natural heritage. The zone will establish a distance between drinking water intakes, and ensure that sediment dredging and other construction-related activities do not impact drinking water quality, and ensure that potential noise levels are within acceptable levels. The zone will establish a distance between near-shore activities and wind facilities, and also help to maintain the ecological health of inland waters. Guidelines and technical requirements for wind facility operators were also included.

    Approximately 20% of all deaths in the USA occur in the intensive care unit (ICU) and the majority of ICU deaths involves decision of de-escalation of life-sustaining interventions. Life-sustaining interventions may include intubation and mechanical ventilation, artificial nutrition and hydration, antibiotic treatment, brain surgery, or vasoactive support. Decision making about goals of care can be defined as an end-of-life communication and the decision-making process between a clinician and a patient (or a surrogate decision maker if the patient is incapable) in an institutional setting to establish a plan of care. This process includes deciding whether to use life-sustaining treatments. Therefore, family discussion is a critical element in the decision-making process throughout the patient's stay in the neurocritical care unit. A large part of care in the neurosciences intensive care unit is discussion of proportionality of care. This chapter provides a stepwise approach to hold these conferences and discusses ways to do it effectively. © 2017 Elsevier B.V. All rights reserved.

    The topics here deal with some current progress in electromagnetic wave propagation in a family of substances known as metamaterials. To begin with, it is discussed how a pulse can develop a leading edge that steepens and it is emphasised that such self-steepening is an important inclusion within a metamaterial environment together with Raman scattering and third-order dispersion whenever very short pulses are being investigated. It is emphasised that the self-steepening parameter is highly metamaterial-driven compared to Raman scattering, which is associated with a coefficient of the same form whether a normal positive phase, or a metamaterial waveguide is the vehicle for any soliton propagation. It is also shown that the influence of magnetooptics provides a beautiful and important control mechanism for metamaterial devices and that, in the future, this feature will have a significant impact upon the design of data control systems for optical computing. A major objective is fulfiled by the investigations of the fascinating properties of hyperbolic media that exhibit asymmetry of supported modes due to the tilt of optical axes. This is a topic that really merits elaboration because structural and optical asymmetry in optical components that end up manipulating electromagnetic waves is now the foundation of how to operate some of the most successful devices in photonics and electronics. It is pointed out, in this context, that graphene is one of the most famous plasmonic media with very low losses. It is a two-dimensional material that makes the implementation of an effective-medium approximation more feasible. Nonlinear non-stationary diffraction in active planar anisotropic hyperbolic metamaterials is discussed in detail and two approaches are compared. One of them is based on the averaging over a unit cell, while the other one does not include sort of averaging. The formation and propagation of optical spatial solitons in hyperbolic metamaterials is also

  16. Elaboration of a concept for modelling creep damage and rupture processes in structural components made of heat-resistant CrMoV steels, considering multi-axial stress regimes and formation of pores. Final report

    The research project was intended to study and elaborate models describing the creep performance of heat-resistant CrMoV steels over the entire creep regime, including the damage processes (tertiary creep). The mathematical description of the creep performance and damages induced is required for the calculation of deformation, stresses and damage affecting structural components over their service life, so that information can be derived about their remanent life. The objective was achieved by describing the interaction between deformation and damage due to cavitation. A model was elaborated that uses an anisotropic cavitation parameter (tensor). The model was tested with and adapted to the material X 20 CrMoV 12 1 and its behaviour at 550 C using data obtained through uni-axial creep tests at constant loading. The modified model was used for recalculation of a long-term experiment at MPA Stuttgart, performed at 550 C with a pipe elbow made of the charge-identical material X 20 XrMoV 12 1, applying the ABAQUS FE program. Mechanical total strains calculated for selected nodes are in good agreement with corresponding measured data. (orig./CB) [de

    This paper aims at understanding the social and political uses of the principle of integrated management and its possible impacts on the elaboration and implementation processes of public policies in the French water management field. The academic and political innovations developed by scientists and agents of the administration these last 25 years are analysed, using some of the theoretical tools developed by the science studies and public policy analysis. We first focus on the construction of intellectual public policy communities such as the GIP Hydro systems, at the origin of large interdisciplinary research programs in the 1990s. A common cognitive framework is clearly built during this period on the good governance of the aquatic ecosystems and on the corresponding needs and practices of research. The second part of the paper focuses on the possibilities to build political communities and more or less integrated expertises in the decision making processes concerning various issues related to water management. Eutrophication and its inscription on the French political agenda is a very significant case for analysing the difficulty to build such a political community. On the contrary, when there is an opportunity for policy evaluation, which was the case concerning the management of wetlands in France or the implementation of compulsory flows on the French rivers, these communities can emerge. However, the type of integrated expertise and management proposed in these cases of policy evaluations much depends on their methodological choices.

    Waste bagasse of Agave tequilana-Weber fibers treated with sodium hydroxide was used to elaborate hydrogel films. The bagasse was offered in an alternative use for the preparation of hydrogel films by phase inversion method without crosslinking and further purification of cellulose. The effect on the properties of the obtained films was studied when the chemical treatment of the agave fibers was changed. It was found that the resultant hydrogels showed increment in tensile from 40 N/mm(2) to 56 N/mm(2) with the increase of sodium hypochlorite concentration from 1 to 10 vol.%, respectively. With regard to biocompatibility properties of the hydrogel films, platelet adhesion, clotting time and protein adsorption were investigated. Analysis of the morphology of adherent NIH3T3 fibroblast indicated that the projected cell area, aspect ratio and long axis gradually increased with the increment of sodium hypochlorite content in the agave treatment. It was presented that the chemical treatment affects cell adhesion and morphology and lignin content remains in the brown fibers. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available ABSTRACT Whey has proteins of high biological value, which has been used as an ingredient in the elaboration of yogurt, milk beverages and as protein concentrates. Food extrusion stands out as one of the most efficient cooking techniques, allowing a number of product types, from soluble flour to convenience products, such as snacks, which have high acceptability by the consumers. Products processed by extrusion, such as those expanded by frying (pellets, have high carbohydrate content, and its enrichment with protein can favor its nutritional aspect. This study aimed to use the whey protein concentrate (WPC in combination with corn grits in the preparation of pellets. Absolute density, density of expanded pellets, color, crispness index, and pellet sensory acceptance were determined. For the absolute density, contents from 5% to 17% produced denser non-expanded pellets. The higher the WPC content and the temperature of the extruder, the higher the density of the expanded pellets. The crispness index was not altered by the protein content and by the extruder temperature. In the sensory analysis, the preferred samples were the ones with lower WPC levels (5%. We concluded that higher WPC values in the pellets formulation increased their density, but did not alter color and texture, as well as small WPC levels did not affect the acceptance of snacks.

    Nutritional epidemiology is an inherently complex and multifaceted research area. Dietary intake is a complex exposure and is challenging to describe and assess, and links between diet, health, and disease are difficult to ascertain. Consequently, adequate reporting is necessary to facilitate comprehension, interpretation, and generalizability of results and conclusions. The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement is an international and collaborative initiative aiming to enhance the quality of reporting of observational studies. We previously presented a checklist of 24 reporting recommendations for the field of nutritional epidemiology, called "the STROBE-nut." The STROBE-nut is an extension of the general STROBE statement, intended to complement the STROBE recommendations to improve and standardize the reporting in nutritional epidemiology. The aim of the present article is to explain the rationale for, and elaborate on, the STROBE-nut recommendations to enhance the clarity and to facilitate the understanding of the guidelines. Examples from the published literature are used as illustrations, and references are provided for further reading.
