    Dubois, Amandine; Rattaz, Cécile; Pry, René; Baghdadli, Amaria

    2010-01-01

    La présente analyse bibliographique a pour objectif de réaliser un bilan des travaux publiés dans le champ de la douleur et de l’autisme. L’article aborde, dans un premier temps, les études publiées concernant les modes d’expression de la douleur observés dans cette population. Différentes hypothèses permettant d’expliquer les particularités expressives des personnes avec autisme sont ensuite passées en revue : excès d’endorphines, particularités dans le traitement sensoriel, déficit sociocommunicatif. Cette analyse bibliographique aborde, pour terminer, la question de l’évaluation et de la prise en compte de la douleur chez les personnes avec autisme. Les auteurs concluent à l’absence d’homogénéité des résultats des études publiées et au besoin de poursuivre les recherches afin de parvenir à des données consensuelles sur un domaine d’étude encore peu exploité au plan scientifique. Sur un plan clinique, l’approfondissement des connaissances dans ce domaine devrait permettre de mettre au point des outils d’évaluation de la douleur et d’ainsi en assurer une meilleure prise en charge au quotidien.

    Many industrial activities need the storage of liquefied gas, on the site. These gases are often toxic and easily set on fire. The aim of this study is to realize a tool taking into account an obstacle and a release following a pipe breaking, which is one of the most widely prevalent configuration in the industry. The first part presents a bibliographic study to take stock on the two phase jet simulation and a drop impact on a solid surface. In the second part, the described models have been used to realize a first simulation in order to evaluate the quantity of collected product by an obstacle placed on the two phase jet trajectory.

  1. Theoretical and bibliographic synthesis on micro-heat pipes; Synthese theorique et bibliographique sur les microcaloducs

    Sartre, V.; Lallemand, M. [Institut National des Sciences Appliquees (INSA), 69 - Villeurbanne (France)

    1996-12-31

    The technology, dimensioning and performances of heat pipes are well known since several years. Micro-heat pipes occurred more recently with the miniaturization of systems to be cooled and the increase of surface heat fluxes to be dissipated. Publications concerning this topic are not much older than the 90`s. Using these papers, a bibliographic synthesis on micro-heat pipe performances, functioning and dimensioning is presented. Experimental studies demonstrate the efficiency of such systems but also their high sensitivity with respect to the capillary limit which leads to a progressive drying of the evaporator and a reduction of its thermal conductance. Theoretical studies are based on the same equations than heat pipes. More or less complex models have been proposed in the literature and a relatively simple model is presented in this paper. These studies have permitted to show the great influence of some parameters on micro-heat pipes functioning like: the pipe geometry, the fluid-wall contact angle, the level of pipes filling, and the bonding zone of the liquid film on the wall.

  4. Etude bibliographique des principales caractéristiques de l'écologie des larves d'Acipenseridés

    Directory of Open Access Journals (Sweden)

    JATTEAU P.

    1998-07-01

    Full Text Available Cette synthèse bibliographique fait le point sur les connaissances concernant les principaux traits de l'écologie des larves d'acipenseridés. Le comportement des larves évolue avec l'âge, de l'éclosion jusqu'au début de l'alimentation strictement exogène, et peut être décrit selon 4 étapes, en prenant comme critères principaux l'activité natatoire et la position par rapport au substrat. Les observations en milieu naturel montrent une évolution des preferendum de substrat, allant vers une diminution de la granulométrie moyenne. Ces résultats sont en accord avec les données comportementales et sont également expliqués par le passage à l'alimentation exogène. La recherche de nourriture se fait par l'intermédiaire du goût dès le début de l'alimentation mixte, puis l'olfaction devient prépondérante chez les larves plus âgées. Par contre la vision, très peu développée chez l'esturgeon, ne semble pas intervenir. Le spectre alimentaire des larves est restreint. Il se compose presque exclusivement de larves d'insectes et, plus particulièrement, de larves de chironomidés. Ce travail préliminaire a mis en évidence le manque de résultats issus du milieu naturel, ce qui ne permet généralement pas de valider les informations tirées des expérimentations réalisées en laboratoire. Néanmoins, il semble acquis que les phases d'activité en pleine eau, identifiées en structures expérimentales, correspondraient aux périodes de déplacement mises en évidence par les captures dans le milieu naturel. La dérive passive des larves puis leur migration seraient expliquées d'abord par un nombre limité d'habitats favorables dans la zone d'incubation et, ultérieurement, par les disponibilités alimentaires.

    Barnett, Michael D; Parsons, Thomas D; Reynolds, Brooke L; Bedford, Lee A

    2018-01-01

    Guides to neuropsychological assessment emphasize the importance of establishing rapport; however, there has been a minimal amount of empirical investigation of the impact of rapport on neuropsychological test performance. In this experiment, participants (N = 98) were randomly assigned to take neuropsychological tests in either a high or low rapport condition. Results showed that we were able to manipulate the level of rapport and that the level of rapport had a significant effect on the Grooved Pegboard Test and the Controlled Oral Word Association Test, with other tests nearing statistical significance. These results suggest that the level of rapport may affect neuropsychological test performance.

  9. On Rapport Uncertainty in the Sharing Economy

    DEFF Research Database (Denmark)

    Frey, Alexander; Trenz, Manuel; Tan, Chee-Wee

    2018-01-01

    Sharing Economy platforms enable a close physical interaction among strangers by mediating goods and services owned or provided by individuals. This close physical interaction is an inherent part of the service experience, is highly individual and thus can hardly be evaluated beforehand. This gives...... rise to a novel type of service uncertainty that we term as rapport uncertainty. Building on the hierarchical decomposition of service quality, we construct an uncertainty model that encompasses three uncertainty categories consumers face when sharing a resource: rapport, technical, and environment...... uncertainty. Our empirical study in a ride sharing context reveals that rapport uncertainty differs from other categories of uncertainty and significantly reduces the intention to transact with a service provider. Our findings illustrate how the concept of uncertainty must be extended to reflect the nature...

  10. Developing therapeutic rapport: a training validation study.

    Science.gov (United States)

    Norfolk, Tim; Birdi, Kamaljit; Patterson, Fiona

    2009-01-01

    Patient-centred consulting is at the heart of modern medicine, and training programmes now routinely highlight a range of communication skills that enhance the doctor-patient relationship. The present pilot study focuses on the central role played by empathic skills in developing rapport and shared understanding, as captured in a new model developed by the authors. The specific aim of the study was to evaluate the potential of a short-term training programme using this model to improve rapport-related behaviour in general practitioner (GP) trainees. In a quasi-experimental study, 37 GP trainees from schemes in central England (the training group) participated in a training programme based around a new model of therapeutic rapport, with pre- and post-training analysis of relevant knowledge-based, affective and behavioural outcomes. A control group of ten GP trainees, from schemes in a comparable UK medical deanery, took no part in the training programme but were involved in all pre- and post-training analyses. The training group demonstrated significant increases in rapport-related knowledge and all three affective dimensions (attitudes, confidence and motivation); there was a similar finding in terms of 'positive engagement' and all expert-rated aspects of rapport-related behaviours. The control group showed no comparable improvement in any area, and recorded a significant drop in demonstration of positive engagement behaviours. The significant improvement in rapport-related knowledge, attitudes and behaviour after training, and the lack of any comparable change in the control group, gives some support to the suggestion that the module (and the model that underpinned it) may have triggered such an impact independent of ongoing experience or other educational activities.

    2013-10-01

    Physicians' negative attitudes toward patients with obesity are well documented. Whether or how these beliefs may affect patient-physician communication is unknown. To describe the relationship between patient body mass index (BMI) and physician communication behaviors (biomedical, psychosocial/lifestyle, and rapport building) during typical outpatient primary care visits was aimed. Using audio-recorded outpatient encounters from 39 urban primary care physicians (PCPs) and 208 of their patients, the frequency of communication behaviors using the Roter Interaction Analysis System was examined. The independent variable was measured; patient BMI and dependent variables were communication behaviors by the PCP within the biomedical, psychosocial/lifestyle, and rapport building domains. A cross-sectional analysis using multilevel Poisson regression models to evaluate the association between BMI and physician communication was performed. PCPs demonstrated less emotional rapport with overweight and obese patients (incidence rate ratio, IRR, 0.65, 95%CI 0.48-0.88, P = 0.01; IRR 0.69, 95%CI 0.58-0.82, P rapport in primary care visits with overweight and obese patients may weaken the patient-physician relationship, diminish patients' adherence to recommendations, and decrease the effectiveness of behavior change counseling.

    Science.gov (United States)

    Price, Bob

    2017-08-09

    Rapport is established at the first meeting between the patient and nurse, and is developed throughout the therapeutic relationship. However, challenges can arise during this process. Initially, nurses can establish trust with the patient through the questions they ask, however, as care progresses, the nurse will be required to demonstrate a commitment to maintaining the patient's psychological well-being. When the therapeutic relationship ends, the nurse should assist the patient to assess progress and plan the next stage of recovery. This article provides three reflective exercises using case study examples to demonstrate how rapport is developed and sustained. Evidence is provided to identify why challenges arise in the therapeutic relationship and how the nurse can ensure they provide care that the patient regards as genuine.

  18. Revenge versus rapport: Interrogation, terrorism, and torture.

    Science.gov (United States)

    Alison, Laurence; Alison, Emily

    2017-04-01

    This review begins with the historical context of harsh interrogation methods that have been used repeatedly since the Second World War. This is despite the legal, ethical and moral sanctions against them and the lack of evidence for their efficacy. Revenge-motivated interrogations (Carlsmith & Sood, 2009) regularly occur in high conflict, high uncertainty situations and where there is dehumanization of the enemy. These methods are diametrically opposed to the humanization process required for adopting rapport-based methods-for which there is an increasing corpus of studies evidencing their efficacy. We review this emerging field of study and show how rapport-based methods rely on building alliances and involve a specific set of interpersonal skills on the part of the interrogator. We conclude with 2 key propositions: (a) for psychologists to firmly maintain the Hippocratic Oath of "first do no harm," irrespective of perceived threat and uncertainty, and (b) for wider recognition of the empirical evidence that rapport-based approaches work and revenge tactics do not. Proposition (a) is directly in line with fundamental ethical principles of practice for anyone in a caring profession. Proposition (b) is based on the requirement for psychology to protect and promote human welfare and to base conclusions on objective evidence.

    2006-11-01

    Full Text Available Dans cette étude bibliographique, on décrit les méthodes d'obtention des silicates alcalins ainsi que leurs propriétés et les propriétés de leurs polymères en insistant sur l'influence du pH, de la concentration et de la température sur la polymérisation et les caractéristiques des polymères obtenus. On présente ensuite le mode d'obtention des mousses à partir de solutions aqueuses de silicates, ainsi que leurs propriétés et l'influence de divers additifs tels que les agents tensioactifs, moussants, gélifiants ou les agents de durcissement sur les propriétés des mousses. II ressort de cette bibliographie que des mousses polysilicates solubles peuvent être obtenues à partir de solutions de silicates à faible rapport molaire SiO2/Na2O. Par ailleurs, en faisant varier la composition des solutions de silicates alcalins et par l'emploi d'additifs, il est possible de produire une gamme très variée de mousses polysilicates dont les propriétés d'isolation, de solubilité et de résistance mécanique, voire de perméabilité, sont très variées, ce qui leur ouvre la voie à de nombreuses possibilités de débouchés industriels. This article gives a bibliographic description of methods for obtaining alkaline silicates as well as their properties and the properties of their polymers. Emphasis is placed on the influence of the pH, and on the influence of the concentration and temperature on the polymerization and the characteristics of the polymers obtained. Then a method is recommended for obtaining foams from aqueous silicate solutions together with the properties of such foams and the influence of different additives such as surfactants, foaming agents, gelling agents and hardening agents on the properties of foams. This bibliographic study shows that soluble polysilicate foams may be obtained from silicate solutions with a low SiO2/Na2O molar ratio. Furthermore, by varying the composition of alkaline silicate solutions and by

  1. Examining the positive effects of rapport building: when and why does rapport building benefit adult eyewitness memory?

    Science.gov (United States)

    Kieckhaefer, Jenna Mitchell; Vallano, Jonathan Patrick; Schreiber Compo, Nadja

    2014-01-01

    Most investigative interviewing protocols recommend building rapport with cooperative adult witnesses to increase the accuracy of their reports. Although a few recent studies support the benefits of rapport building on adult witness recall, no study has examined whether the timing of rapport in relation to post-event misinformation affects recall accuracy, and whether these effects are related to witness anxiety levels throughout the interview. The present study provided two hundred and thirty-three undergraduates with a videotaped mock crime followed by building high or low rapport either before or after they received post-event misinformation. All witnesses were then interviewed about the mock crime. Results indicated that high rapport before misinformation increased the amount of accurate information reported in a subsequent witness interview compared to low rapport. However, these recall benefits were not due to a reduction in anxiety. Theoretical implications and practical recommendations for police interviewing practices are discussed.

    Leitner, Jordan B; Ayduk, Özlem; Boykin, C Malik; Mendoza-Denton, Rodolfo

    2018-01-01

    Research suggests that interracial mentoring relationships are strained by negative affect and low rapport. As such, it stands to reason that strategies that decrease negative affect and increase rapport should improve these relationships. However, previous research has not tested this possibility. In video-chats (Studies 1 and 2) and face-to-face meetings (Study 3), we manipulated the degree of mutual self-disclosure between mentees and mentors, a strategy that has been shown to reduce negative affect and increase rapport. We then measured negative affect and rapport as mediators, and mentee performance (quality of speech delivered; Studies 1 and 3) and mentor performance (warmth and helpfulness; Studies 2 and 3) as key outcomes. Results revealed that increased self-disclosure decreased negative affect and increased rapport for both mentees and mentors. Among mentees, decreased negative affect predicted better performance (Studies 1 and 3). Among mentors, increased rapport predicted warmer feedback (Studies 2 and 3). These effects remained significant when we meta-analyzed data across studies (Study 4), and also revealed the relationship of rapport to more helpful feedback. Findings suggest that affect and rapport are key features in facilitating positive outcomes in interracial mentoring relationships.

    Full Text Available Positive relationships between instructors and students are critical to effective learning in the classroom. Rooted in the Scholarship of Teaching and Learning (SoTL, and centered at the crossroads of interpersonal communication and instructional communication (Affective Learning Model, this study examines how instructors in a Taiwan ESL school build relationships with Taiwanese students. Instructors were interviewed regarding the behaviors they use to build rapport with their students. Results show that instructors build rapport with their students using several specific techniques: uncommonly attentive behaviors, common grounding behaviors, courteous behaviors, connecting behavior, information sharing behavior, a balancing of connection and authority, adaptation of rapport to student level, and provision of a respite to norms. The findings provide specific examples of how instructors can build rapport in intercultural classrooms.

  13. An ecological examination of rapport using a dyadic puzzle task.

    Science.gov (United States)

    Grahe, Jon E; Sherman, Ryne A

    2007-10-01

    Previous studies have indicated that situational context impacts the rapport experience (e.g., F. J. Bernieri, J. S. Gillis, J. M. Davis, & J. E. Grahe, 1996; N. M. Puccinelli, L. Tickle-Degnen, & R. Rosenthal, 2003). The authors designed the present study to further document the behavioral and experiential predictors of dyadic rapport and to evaluate dyadic rapport experiences when contributions were required from both interactants. Participants (N = 60) were paired into dyads and instructed to complete children's puzzles. However, the dyadic members were restricted in how they could accomplish this task: Only one interactant was allowed to work on the puzzle and had to do so blindfolded, while the second interactant gave instructions. Results suggested that less attribution of responsibility to the worker and the instructor's experience of enjoyment and frustration were indicative of higher rapport. Other characteristics of dyads reporting higher dyadic rapport included difficulty completing the task and more communicative behavior. The results provide important information for the understanding of the dyadic experience of rapport.

    To measure rapport between medical students and standardized patients using observer ratings; to relate these ratings to students' emotional awareness and to behavior within the medical interaction; and to assess the relative validity of using excerpts of different lengths for the measurement of rapport. Third-year medical students (N=141) were videotaped during a 15-min interaction with a standardized patient, and rapport as well as other communication variables were measured using trained coders. Rapport was measured with good interrater reliability by trained coders who viewed three 1-min excerpts. Emotional awareness was measured by a test of recognizing facial expressions of emotion, self-ratings of emotional self-awareness, and peer ratings of interpersonal sensitivity. Finally, participants who viewed the videotapes while imagining themselves to be the patient (analogue patients) provided impressions of the students, including satisfaction. Rapport based on all three minutes was positively correlated with accuracy in decoding facial expressions of emotion, self-reported attention to one's own emotions, peer ratings of sensitivity, communication behaviors of the medical student and standardized patient, and analogue patients' positive impressions and satisfaction. Rapport based on just the first minute of the interaction was significantly related to many of these variables. Rating short excerpts of behavior is a valid and efficient methodology for capturing the concept of rapport. Clinicians, researchers, and educators should focus on rapport building, even very early in the medical visit.

    Full Text Available Rapport is usually considered key to any interview situation: building the right kind of rapport can be the difference between success and failure in obtaining the required data. In feminist research, rapport is intended to be of a particular kind: created through mutual sharing, minimal power hierarchies, and a feeling of genuine trust between interviewer and interviewee (Oakley, 1981. There is a tension here of which feminist researchers and scholars should remain critical, as the idea of good feminist rapport can clash with the necessity of “getting the data.” Building rapport can entail minimising strongly held viewpoints, working hard on one’s emotions to ensure they do not reveal true thoughts, or suggesting an attitude of trust and mutual understanding that may feel disingenuous. If rapport is often a performance by the researcher, then this can clash with the intended open and honest feminist approach. In some cases, then, building rapport may pose a challenge to genuinely following a feminist approach to the research interview. In this paper, I wish to explore this tension in more detail in the context of the one-off interview and to what extent it can be resolved.

    Motivated by NASA's need for high-assurance software, NASA Ames' Amphion project has developed a generic program generation system based on deductive synthesis. Amphion has a number of advantages, such as the ability to develop a new synthesis system simply by writing a declarative domain theory. However, as a practical matter, the validation of the domain theory for such a system is problematic because the link between generated programs and the domain theory is complex. As a result, when generated programs do not behave as expected, it is difficult to isolate the cause, whether it be an incorrect problem specification or an error in the domain theory. This paper describes a tool we are developing that provides formal traceability between specifications and generated code for deductive synthesis systems. It is based on extensive instrumentation of the refutation-based theorem prover used to synthesize programs. It takes augmented proof structures and abstracts them to provide explanations of the relation between a specification, a domain theory, and synthesized code. In generating these explanations, the tool exploits the structure of Amphion domain theories, so the end user is not confronted with the intricacies of raw proof traces. This tool is crucial for the validation of domain theories as well as being important in everyday use of the code synthesis system. It plays an important role in validation because when generated programs exhibit incorrect behavior, it provides the links that can be traced to identify errors in specifications or domain theory. It plays an important role in the everyday use of the synthesis system by explaining to users what parts of a specification or of the domain theory contribute to what pieces of a generated program. Comments are inserted into the synthesized code that document these explanations.

    The generation of cw-THz radiation by photomixing is particularly suited to the high resolution spectroscopy of gases; nevertheless, until recently, it has suffered from a lack of frequency metrology. Frequency combs are a powerful tool that can transfer microwave frequency standards to optical frequencies and a single comb has permitted accurate (10-8) THz frequency synthesis with a limited tuning range. A THz synthesizer composed of three extended cavity laser diodes phase locked to a frequency comb has been constructed and its utility for high resolution gas phase spectroscopy demonstrated. The third laser diode allows a larger tuning range of up to 300 MHz to be achieved without the need for large frequency excursions, while the frequency comb provides a versatile link to be established from any traceable microwave frequency standard. The use of a single frequency comb as a reference for all of the cw-lasers eliminates the dependency of synthesized frequency on the carrier envelope offset frequency. This greatly simplifies the frequency comb stabilization requirements and leads to a reduced instrument complexity.

    Energy Technology Data Exchange (ETDEWEB)

    2008-07-01

    A 'Business as usual' or 'Baseline' scenario of energy trends to 2020-2030 is produced by France every four years, as requested by the International Energy Agency in order to update the global scenarios published in its World Energy Outlook. Since the most recent scenario of this type was drawn up in 2003-2004, the time has come to renew the effort for the IEA's next in-depth review of French energy policy. Specifically, the DGEMP seeks to predict the future of France's energy situation assuming that no policies or new measures are taken affecting (i.e. improving or deteriorating) the situation other than those already in place or adopted as of 1 January 2008 (in other words, before measures such as those stemming from the Grenelle Environment Forum). On the other hand, it is assumed that change in the energy system is guided by 'conventional wisdom' according to which political options and behaviours by economic units are expected to be 'reasonable'. As a result, even should its projections prove inappropriate, this cannot be considered a 'worst-case' scenario. Indeed, beyond the IEA, this scenario can be used to establish an MEA (Multilateral Environment Agreement) scenario (based on existing measures) for national communications submitted under the U.N. Climate Convention. The scenarios by the 'Energy' Commission, part of the Centre d'Analyse Strategique (CAS), could have been used, particularly since the consultant who worked with the CAS to develop its scenarios was also commissioned by the DGEMP. However, several considerations argued in favour of proceeding separately: - The CAS scenarios drew on the DGEMP's 2004 baseline scenario, even though certain parameters were updated (in particular energy prices). - Moreover, the concept underpinning the DGEMP baseline scenario is that it should to every extent possible remain constant over time to secure continued consensus on this 'reference' at national level. - Finally, the MEDEE energy demand model applied in the CAS scenarios relies primarily on 2000 data, despite the existence of sufficiently complete statistics through to 2005. The DGEMP on the other hand used a study by the BIPE (Office for Economic Information and Forecasting) provided by the SESP, the Ministry for Ecology, Energy, Sustainable Development and Spatial Planning's economic statistics and forecasting department. On the basis of the study's macro-economic projections of the French economy to 2020, the DGEMP was able to re-evaluate the prospects for activity in the industrial and tertiary sectors. In several respects (e.g. supply security, CO{sub 2} emissions, energy efficiency), the baseline scenario proposed here is clearly not a scenario conducive to satisfying French energy policy objectives. This is not a surprising conclusion in that it implies the need to implement new policies and measures in addition to those already in place or approved. In particular, this scenario would lead to importing 66 billion cubic meters of gas (59 Mtoe) in 2020 and 78 billion cubic meters (70 Mtoe) in 2030, compared with the present 44 billion cubic meters. In addition to the resulting CO{sub 2} emissions, the near doubling of gas imports would pose a twofold problem as to the geographic origin of the gas imported (under appropriate supply contracts) and the infrastructure (LNG terminals, gas pipelines) required to transport it. Finally, the baseline scenario is of course a long way from achieving the Community targets, whether for CO{sub 2} emissions, projected to rise continually until 2020 and then even faster until 2030 (due to transport and electric power generation), or for the share of renewable energy in the energy mix. In that regard, the share of renewable energy in 'enlarged' final energy consumption, as it is described in the 'energy and climate change package', would grow to 13.4% in 2020 (versus 23% in the Commission's burden sharing proposal) and to 13.7% in 2030, compared with the 10.3% share observed in 2006.

    Extraverts are better than introverts at building rapport, but it remains unknown what they do behaviorally to better connect with other individuals. We hypothesized that extraverts mimic more than introverts as a way to build rapport; however, we predicted that this social skillfulness of extraverts emerges only when they are motivated to affiliate. In Study 1, we found that extraversion predicted increased mimicry when an affiliation goal was present, but not when an affiliation goal was absent. In Study 2, we found that mimicry mediates the relationship between extraversion and rapport, but only when an affiliation goal is present. Our findings are the first to identify a behavior that extraverts engage in that helps them build rapport. Furthermore, our studies show that this skillfulness of extraverts emerges only when they are motivated to affiliate, providing evidence in favor of the reward-sensitivity-as-core model of extraversion over the sociability-as-core model of extraversion. © The Author(s) 2015.

    Rapport is a primary component in the development of a therapeutic relationship between health-service professionals and clients. Presession pairing is a procedure often recommended in behavior analytic practice to build rapport with clients. However, many service providers may not exhibit presession pairing skills correctly or at a sufficient rate. The current study aimed to operationally define therapist behaviors that are indicative of presession pairing and to train direct care staff to implement said skills.

  2. Interviewing Practices, Conversational Practices, and Rapport: Responsiveness and Engagement in the Standardized Survey Interview.

    Science.gov (United States)

    2016-08-01

    "Rapport" has been used to refer to a range of positive psychological features of an interaction -- including a situated sense of connection or affiliation between interactional partners, comfort, willingness to disclose or share sensitive information, motivation to please, or empathy. Rapport could potentially benefit survey participation and response quality by increasing respondents' motivation to participate, disclose, or provide accurate information. Rapport could also harm data quality if motivation to ingratiate or affiliate caused respondents to suppress undesirable information. Some previous research suggests that motives elicited when rapport is high conflict with the goals of standardized interviewing. We examine rapport as an interactional phenomenon, attending to both the content and structure of talk. Using questions about end-of-life planning in the 2003-2005 wave of the Wisconsin Longitudinal Study, we observe that rapport consists of behaviors that can be characterized as dimensions of responsiveness by interviewers and engagement by respondents. We identify and describe types of responsiveness and engagement in selected question-answer sequences and then devise a coding scheme to examine their analytic potential with respect to the criterion of future study participation. Our analysis suggests that responsive and engaged behaviors vary with respect to the goals of standardization-some conflict with these goals, while others complement them.

    In the exploratory study reported here, we tested the efficacy of an intervention designed to train teenagers with Möbius syndrome (MS) to increase the use of alternative communication strategies (e.g., gestures) to compensate for their lack of facial expressivity. Specifically, we expected the intervention to increase the level of rapport experienced in social interactions by our participants. In addition, we aimed to identify the mechanisms responsible for any such increase in rapport. In the study, five teenagers with MS interacted with three naïve participants without MS before the intervention, and with three different naïve participants without MS after the intervention. Rapport was assessed by self-report and by behavioral coders who rated videos of the interactions. Individual non-verbal behavior was assessed via behavioral coders, whereas verbal behavior was automatically extracted from the sound files. Alignment was assessed using cross recurrence quantification analysis and mixed-effects models. The results showed that observer-coded rapport was greater after the intervention, whereas self-reported rapport did not change significantly. Observer-coded gesture and expressivity increased in participants with and without MS, whereas overall linguistic alignment decreased. Fidgeting and repetitiveness of verbal behavior also decreased in both groups. In sum, the intervention may impact non-verbal and verbal behavior in participants with and without MS, increasing rapport as well as overall gesturing, while decreasing alignment.

  4. When rapport building extends beyond affiliation: communication overaccommodation toward patients with disabilities.

    2011-01-01

    Physician rapport with patients is described as a vital component of relationship-centered care, but rapport-building communication behaviors may exceed boundaries and instead indicate patronizing behavior toward patients with disabilities. This paper addresses the types of communication behaviors and contexts for interpreting when rapport building extends beyond boundaries toward patients with disabilities. Videotaped interactions between third- and fourth-year medical students (N = 142) and standardized patient educators with physical disabilities were qualitatively analyzed. Results suggest six primary themes of exceeding expected rapport boundaries, including baby talk (ie, exaggerated nonverbal gestures and "we" language to indicate "you"), kinesic movement (ie, stiff posture and awkward handshakes), vocalics (ie, volume or pitch that interfered with the flow of conversation), relationship assumptions (ie, communicating assumptions that relationships were grounded in care-receiving), emotional divergence from patient disclosure (ie, minimizing or embellishing disability), and inconsistency with patient emotional cues (ie, responding to negative or neutral disclosure by overly accentuating positive interpretation). This study suggests that communication behaviors generally described as positive, rapport-building behaviors can pose negative implications when they exceed the expected quantity or duration, when they are inconsistent with patient verbal disclosure, or when verbal and nonverbal messages are inconsistent. Identified themes serve as examples to understand when rapport building exceeds beyond affiliation and instead appears to indicate patronizing behavior toward patients with disabilities. Suggestions for interpreting communication behaviors within the context of patient disclosure and building capacity to distinguish attitudes and biases limiting communication are addressed.

Observer-coded gesture and expressivity increased in participants with and without MS, while overall linguistic alignment decreased. Fidgeting and repetitiveness of verbal behavior also decreased in both groups. In sum, the intervention may impact nonverbal and verbal behavior in participants with and without MS, increasing rapport as well as overall gesturing, while decreasing alignment.

    The rapport between facilitators and learners contributes to a conducive learning environment during simulation debriefing, but a theory to guide rapport management (RM) is lacking. The RM model is a potentially relevant conceptual framework because it describes three interrelated components of rapport-face, rights, and goals-which, when threatened, affect the rapport between interactants. This critical review explores how studies in the simulation debriefing literature describing postevent facilitator-guided debriefing approaches can be viewed through the lens of the RM model. All 34 identified studies alluded to at least one component of rapport, with less than half alluding to all three. There is preliminary evidence that the management of all three components of rapport during debriefing may contribute to improving short-term learning outcomes. Future studies could explore how the RM model can be used to guide debriefing approaches in various contexts and clarify why or how these approaches work.

    People mimic each other's actions and postures during everyday interactions. It is widely believed this mimicry acts as a social glue, leading to increased rapport. We present two studies using virtual reality to rigorously test this hypothesis. In Study 1, 50 participants interacted with two avatars who either mimicked their head and torso movements at a 1 or 3 second time delay or did not mimic, and rated feelings of rapport and trust toward the avatars. Rapport was higher towards mimicking avatars, with no effect of timing. In Study 2, we aimed to replicate this effect in a pre-registered design and test whether it is modulated by cultural ingroup-outgroup boundaries. Forty participants from European or East Asian backgrounds interacted with four avatars, two of European appearance and two of East Asian appearance. Two avatars mimicked while the other two did not. We found no effects of mimicry on rapport or trust ratings or implicit trust behaviour in a novel maze task, and no effects of group status or interactions. These null results were calculated in line with our pre-registration. We conclude that being mimicked does not always increase rapport or trust, and make suggestions for future directions.

    2015-08-01

    The vast majority of guidelines recommend that developing rapport with children is essential for successful forensic child interviewing; however, the question remains as to whether there is a sufficient body of scientific research to generate evidence-based guidelines for developing rapport with children in legal contexts. To answer this question, we conducted a systematic review of the literature to identify experimental studies of the effects of rapport-building methods on the reliability of children's reports. Independent raters applied 12 exclusion criteria to the 2,761 potentially relevant articles located by electronic and hand searches of the literature. Experimental studies were few. Although studies to date are a beginning, the overall scientific base is weak regarding even basic issues such as how to best define rapport and the efficacy of common rapport-building techniques. This systematic review highlights what we know, what we do not know, and how much more we need to know to create evidence-based best practice. Recommendations for reshaping the research agenda are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

    The purpose of this study was to describe the special considerations for building rapport and establishing a therapeutic alliance when conducting mental health evaluations for children and adolescents via videoconferencing. The authors review the literature and describe their experience in conducting mental health evaluations, developing rapport, and establishing a therapeutic alliance during telemental health practice. Clinical need and shortages of clinicians with expertise in evaluating mental conditions for children and adolescents in underserved communities have stimulated the rapid expansion of telemental health programs while the research base continues to develop. The emerging evidence base and clinical experience suggest that teleclinicians can, and do, build rapport and establish a therapeutic alliance during telemental health sessions with youth and families. Families may be more accepting of telemental health approaches than clinicians. The impact that technology, equipment, site staff, community supports, cultural identification, and teleclinicians' characteristics have on building rapport and establishing a therapeutic alliance should be considered when establishing a telemental health service. Staff at the patient site and referring providers have a valuable role in supporting the therapeutic alliance between telemental health providers and their patients, and ultimately supporting the success of a telemental health program. Teleclinicians are creative in transcending the videoconferencing technology to evaluate patients using guideline-based care. Further research is needed to determine how clinicians build rapport and establish a therapeutic alliance during telemental health sessions, and whether the therapeutic alliance is associated with the accuracy of evaluation and outcomes.

  11. Do Prosecutors Use Interview Instructions or Build Rapport with Child Witnesses?

    Science.gov (United States)

    Ahern, Elizabeth C; Stolzenberg, Stacia N; Lyon, Thomas D

    2015-08-01

    This study examined the quality of interview instructions and rapport-building provided by prosecutors to 168 children aged 5-12 years testifying in child sexual abuse cases, preceding explicit questions about abuse allegations. Prosecutors failed to effectively administer key interview instructions, build rapport, or rely on open-ended narrative producing prompts during this early stage of questioning. Moreover, prosecutors often directed children's attention to the defendant early in the testimony. The productivity of different types of wh- questions varied, with what/how questions focusing on actions being particularly productive. The lack of instructions, poor quality rapport-building, and closed-ended questioning suggest that children may not be adequately prepared during trial to provide lengthy and reliable reports to their full ability.

    2017-01-01

    Young people suspected of being sexually exploited are unlikely to have made prior disclosures before being approached by authorities, and this can make them especially uncomfortable when involved in investigations. Semistructured interviews were conducted with frontline social workers and law enforcement practitioners about their experiences interacting with youth during child sexual exploitation investigations. The findings provided some tentative insights into the processes by which practitioners sought to establish rapport with young people who have been exploited and establish themselves as trustworthy abuse disclosure recipients. Practitioners reported that rapport building in child sexual exploitation cases not only occurred over lengthy periods of time (e.g., months or years) but also required repeated contacts between the practitioners and young people, during which practitioners minimized their roles as authorities and maximized their authenticity as caring people. Practitioners mentioned the importance of dependability, lightheartedness, and having a casual demeanor. Findings have implications for managing reluctance and understanding rapport building when working with possible victims.

    2014-01-01

    This study tested the effects of narrative practice rapport building (asking open-ended questions about a neutral event) and a putative confession (telling the child an adult "told me everything that happened and he wants you to tell the truth") on 4- to 9-year-old maltreated and nonmaltreated children's reports of an interaction with a stranger who asked them to keep toy breakage a secret (n = 264). Only one third of children who received no interview manipulations disclosed breakage; in response to a putative confession, one half disclosed. Narrative practice rapport building did not affect the likelihood of disclosure. Maltreated children and nonmaltreated children responded similarly to the manipulations. Neither narrative practice rapport building nor a putative confession increased false reports. © 2014 The Authors. Child Development © 2014 Society for Research in Child Development, Inc.

    Rousseau, G.

    1994-02-01

    We first recall the most important definitions about the fluid/structure interaction. We also define some non-dimensional numbers in order to analyze the physical effects in the fluid we have to take into account: viscosity, compressibility, gravity, inertial effect. Then, in the first part called ``Calculation of the added mass: Models``, we explain the equations which allow us to find the added mass on one structure. After that, we deal with the dynamical behaviour of tube bundles immersed in a fluid. We present a two dimensional modelling. Therefore, the fluid structure interaction only takes place in the planes perpendicular to the tube axis. The added mass matrix of the fluid on the whole tubes is built for every kind of cross-section. But we also focus our attention on the special case of circular cross-section. Lastly, when the number of the tubes in the bundle is huge, the direct calculation of the global added mass matrix is impossible: we must use a method of homogenization to describe the global dynamical behaviour of the tube bundles. In particular, the eigenfrequencies of such homogenized medium are determined. We especially focus our attention on the square nuclear fuel bundles immersed in a confined fluid. In the second part called ``Numerical methods used for the fluid structure interaction``, we first tackle the integral methods. However, in these methods, some theoretical and numerical difficulties arise and this fact makes the advantage of a little number of degrees of freedom far less interesting. This leads us to consider the finite element methods. It allows us to determine the added mass matrix of the fluid on the structure expressed with the nodal interpolation functions used by the FE methods. We then propose a discretization of the equations of the movement of tube bundles immersed in a fluid, with or without homogenization. At last, we compare the efficiency of the integral methods to the FE methods. (author). figs., tabs., 54 refs.

  19. Lacan and Adolescence: The Contemporary Clinic of the "Sexual Non-rapport" and Pornography.

    2017-01-01

    This article explores two clinical phenomena-pornography and conspiracy thinking-that are highly relevant today and can be observed specifically among adolescent boys in the early stages of post-puberty: conspiracy thinking and the viewing of pornographic videos. It shows that the Lacanian concepts of the Real (of puberty) and the sexual non-rapport help us understand the psychopathological aspects of these two phenomena. Watching pornographic material becomes equivalent to a conspiracy theory about the sexual non-rapport; both in fact deny the effect of what puberty introduces as radically new.

    Therapeutic rapport between counselors and clients in drug user treatment has been shown to be an important predictor of follow-up outcomes. This naturalistic study investigated the relationship of counseling rapport to drug-related topics discussed in counseling sessions in a sample of 330 clients and nine counselors. These voluntary clients had been admitted to a private, for-profit outpatient methadone treatment in Texas between September 1995 and August 1997 and received no-fee services for a year for participation in this study. The data were gathered using forms in the TCU community treatment assessments (www.ibr.tcu.edu) that measured intake information, counseling session topics, and counselor evaluation of the client. A majority were males, Hispanic, had a pending legal status and the average age was 39. Co-occurring drug dependence for these heroin users included cocaine (38%) and alcohol (31%). The results supported the hypothesis that higher rapport would be associated with addressing clients in a more "supportive approach" that emphasized relapse prevention and strengths-building while lower rapport would be associated with a punitive counseling style that stressed program rules and compliance. The influences of client background, counselor differences, and during-treatment positive urines were also examined. Although counselors differed in their general manner of dealing with clients, each also showed flexibility determined in part by client behavior (such as continued cocaine use). The findings indicate that focusing on constructive solutions is the preferred counseling approach.

  9. The role of empathy in establishing rapport in the consultation: a new model.

    Science.gov (United States)

    Norfolk, Tim; Birdi, Kamal; Walsh, Deirdre

    2007-07-01

    Considerable research has been conducted recently into the notion of patient-centred consulting. The primary goal of this approach is to establish a clear understanding of the patient's perspective on his or her problem, and to allow this understanding to inform both the explanation and planning stages of the consultation. The quality of this understanding is largely determined by the empathic accuracy achieved by the doctor; the primary benefit is a therapeutic rapport between doctor and patient. To highlight the role of empathy and communication skills in establishing rapport, we initially developed a model which seeks to draw the various motivational and skill elements identified in separate research papers into a comprehensive model of the journey towards shared understanding between doctor and patient. We then conducted an initial validation of the model via qualitative analysis involving general practitioners (GPs) and clinical psychologists. The validation offered encouraging support for the principal elements of the model. Specific suggestions for clarification and extension were then incorporated in a revised model. The model appears to capture the dynamic process of establishing a therapeutic relationship (rapport) between doctor and patient, defined by the quality of the doctor's understanding of the patient's perspective on his or her problem. Arguably, the most important contribution of the model is to highlight the fact that 'empathy' and consequent 'rapport' are not mystical or exclusive concepts but, rather, involve the use of specific skills accessible at some level by all.

    Ashton-James, Claire E; Dekker, Peter H; Addai-Davis, Judy; Chadwick, Tom; Zakrzewska, Joanna M; Padfield, Deborah; Williams, Amanda C de C

    2017-08-01

    A variety of treatment outcomes in chronic pain are influenced by patient-clinician rapport. Patients often report finding it difficult to explain their pain, and this potential obstacle to mutual understanding may impede patient-clinician rapport. Previous research has argued that the communication of both patients and clinicians is facilitated by the use of pain-related images in pain assessments. This study investigated whether introducing pain-related images into pain assessments would strengthen various components of patient-clinician rapport, including relative levels of affiliation and dominance, and interpersonal coordination between patient and clinician behaviour. Videos of 35 pain assessments in which pain images were present or absent were used to code behavioural displays of patient and clinician rapport at fixed intervals across the course of the assessment. Mixed modelling was used to examine patterns of patient and clinician affiliation and dominance with consultation type (Image vs Control) as a moderator. When pain images were present, clinicians showed more affiliation behaviour over the course of the consultation and there was greater correspondence between the affiliation behaviour of patient and clinician. However, relative levels of patient and clinician dominance were unaffected by the presence of pain images in consultations. Additional analyses revealed that clinicians responded directly to patients' use of pain images with displays of affiliation. Based on the results of this study, we recommend further investigation into the utility and feasibility of incorporating pain images into pain assessments to enhance patient-clinician communication.

    2016-01-01

    Establishing rapport is an important step in physician-patient communication resulting in a positive effect on patient satisfaction and overall clinical outcomes. However, there is a dearth of studies on the condition of doctor-patient relations in Saudi Arabia. This study was performed to estimate the proportion of physicians who have a good rapport with patients in their practice and the proportion of satisfied attendees. A cross-sectional study was conducted at a Primary Health Care Center, Dammam, KSA. The data were collected through a structured self-administered questionnaire given to samples of attendees and physicians to estimate patient satisfaction and the practice of rapport by physicians. A total of 374 attendees and 27 physicians participated in the study. The percentage of physicians who had good rapport was 51.9%. Factors that showed significant relationship with rapport practice were: Physician's age (p = 0.016), physician's experience (p = 0.043), and professional status (p = 0.031). The attendees satisfied with their physician's rapport with them were 50.5%. Factors that showed significant relationship with satisfaction were: Attendee's age (p rapport with patients and patients' satisfaction with physicians' empathy is not high. Training is required to optimize physician-patient communication.

    Sapienza, R.S.; Sansone, M.J.; Slegeir, W.A.R.

    A method for synthesizing hydrocarbons from carbon monoxide and hydrogen by contacting said gases with a slurry of a catalyst composed of palladium or platinum and cobalt supported on a solid phase is disclosed. The catalyst is prepared by heating a heterogeneous component of the palladium or platinum deposited on the solid support in a solution of cobalt carbonyl or precursors thereof. The catalyst exhibits excellent activity, stability in air, and produces highly desirable product fractions even with dilute gaseous reactants.

    Isocyanates 7 were formed from monoprotected diamines 3 or 6, which in turn can be easily prepared from commercially available N-BOC- or N-FMOC-protected amino acid derivatives. Isocyanates 7, formed in situ, could be coupled directly to a solid support functionalized with amine groups or to amino acids anchored on resins using CH{sub 2}Cl{sub 2} as solvent and an 11 h coupling time at 25 {degree}C. Such couplings afforded peptidomimetics with an N-phthaloyl group at the N-terminus. The optimal conditions identified for removal of the N-phthaloyl group were to use 60% hydrazine in DMF for 1-3 h. Several sequences of amino acids coupled to ureas (`peptidic ureas`) and of sequential urea units (`oligoureas`) were prepared via solid phase syntheses and isolated by HPLC. Partition coefficients were measured for two of these peptidomimetics, and their water solubilities were found to be similar to the corresponding peptides. A small library of 160 analogues of the YGGFL-amide sequence was prepared via Houghten`s tea bag methodology. This library was tested for binding to the anti-{beta}-endorphin monoclonal antibody. Overall, this paper describes methodology for solid phase syntheses of oligourea derivatives with side chains corresponding to some of the protein amino acids. The chemistry involved is ideal for high-throughput syntheses and screening operations. 51 refs., 3 figs., 2 tabs.

  7. Rapport between Cancer Patients and Their Physicians is Critical for Patient Satisfaction with Treatment Decisions.

    2016-01-01

    Cancer patients' satisfaction with their treatment decisions has been demonstrated to be associated with improved health outcomes, but few studies of this issue have been conducted in Japan. To explore key factors in enhancing patient satisfaction, we assessed the association between their satisfaction and their relationships with their physicians. We conducted cross-sectional questionnaire surveys among patients who had received cancer treatment. One source was outpatients from a cancer center hospital, and the other was through the website of Japan's most popular newspaper. The questionnaire included demographic questions and general self-rated life status issues, such as peace of mind, quality of life, daily activities, family relationships, rapport with attending physician, assessment of the physician's explanations, and feelings of happiness during the previous week. Of 576 respondents, 383 subjects said they were satisfied and 193 dissatisfied. It was confirmed that the online survey was comparable to the paper-based survey in examining patient satisfaction. The dissatisfied group included more females and fewer subjects who were forced to retire from jobs than the satisfied group. The patients in the satisfied group had a more favorable subjective opinion of their recent life. The patients in the dissatisfied group received more chemotherapy and had more side effects than those in the satisfied group. Assessment of the physician's role showed significant differences between the two groups; the patients in the satisfied group felt more than those in the dissatisfied group that their physicians' explanations of treatment were sufficient and were satisfied with their rapport with their physicians. Multiple logistic regression analysis revealed that rapport with physicians was a significant factor (odds ratio=3.79, 95% CI=2.25-6.39). Rapport between physicians and patients is one of the most important factors in patient satisfaction with treatment decisions.

  20. Rural multidisciplinary training: opportunity to focus on interprofessional rapport-building.

    Science.gov (United States)

    Hudson, Judith N; Croker, Anne

    2017-01-01

    In 2016, the Australian Government committed further funds in support of quality rural health education to improve the health and wellbeing of rural and remote communities. The stated funding requirement for longer rural placements in all disciplines is an exciting opportunity for greater investment in interprofessional education to foster collaborative practice, a global system imperative for health care. This commentary explores how findings from earlier research, which investigated how students in a co-located area learn to work with other health professions, can be translated into practice. While recognising the importance of an individual's interpersonal capabilities, this commentary focuses on how the core contextual conditions for interprofessional-rapport-building opportunities (shared space, adequate time and balance of disciplines) were considered in one rural centre. Educational leaders and academics globally should recognise that offering health professional students opportunity to live and work together in extended placements in rural settings has potential benefits for interprofessional education. Understanding the contextual conditions for building rapport between health professional learners, and reflecting on these, potentially will lay the foundation for collaborative practice when these learners become health professionals. Through the reflective questions we pose, policy-makers, health managers and clinical leaders from all health disciplines can build on this foundation by considering the interpersonal capability and contextual conditions for rapport-building in the health workforce to foster a collaborative practice environment for graduates to embrace when they enter the health workplace.

    Full Text Available Les travaux de recherche en didactique de l’ecriture sont traverses par deux courants: un courant qui emprunte a differentes sciences sociales la notion de representations; un second courant qui emprunte a la linguistique la notion de formes discursives. Mon propos est d’essayer de mettre en relation ces deux approches. Pour cela, il est organise en trois temps: (a tout d’abord j’evoque les evolutions recentes de la recherche en didactique de l’ecriture, evolutions qui incitent a faire appel a la notion de representations; puis (b j’analyse cette notion. J’explique pourquoi, en didactique de l’ecriture, on utilise la notion de representations sans y adjoindre l’adjectif “sociales”; puis j’explique pourquoi un certain nombre de chercheurs preferent la notion de rapport a l’ecriture a celle de representations de l’ecriture; enfin, (c j’aborde les relations entre le rapport a l’ecrit et l’apprentissage des formes discursives. Pour cela je presente quelques resultats issus d’une recherche de terrain. Je montre comment l’une des dimensions du rapport a l’ecriture – le mode de verbalisation de l’ecriture – peut faire l’objet d’une mise en oeuvre didactique.

  2. Method of synthesizing tungsten nanoparticles

    Science.gov (United States)

    Thoma, Steven G; Anderson, Travis M

    2013-02-12

    A method to synthesize tungsten nanoparticles has been developed that enables synthesis of nanometer-scale, monodisperse particles that can be stabilized only by tetrahydrofuran. The method can be used at room temperature, is scalable, and the product concentrated by standard means. Since no additives or stabilizing surfactants are required, this method is particularly well suited for producing tungsten nanoparticles for dispersion in polymers. If complete dispersion is achieved due to the size of the nanoparticles, then the optical properties of the polymer can be largely maintained.

    Preliminary studies have shown the geothermal potential of deep aquifers in the region named 'La Cote' between the Jura mountain and the Lake of Geneva, between Geneva and Lausanne, Switzerland. The present synthesis report reviews the geological features of the region - known from previous boring - and the expected heat demand in the region. Several sites have been identified where cost-covering operation of a geothermal district heating is expected. Recommendations for the following steps of the project are given.

  4. Synthese de champs sonores adaptative

    Science.gov (United States)

    Gauthier, Philippe-Aubert

    La reproduction de champs acoustiques est une approche physique au probleme technologique de la spatialisation sonore. Cette these concerne l'aspect physique de la reproduction de champs acoustiques. L'objectif principal est l'amelioration de la reproduction de champs acoustiques par "synthese de champs acoustiques" ("Wave Field Synthesis", WFS), une approche connue, basee sur des hypotheses de champ libre, a l'aide du controle actif par l'ajout de capteurs de l'erreur de reproduction et d'une boucle fermee. Un premier chapitre technique (chapitre 4) expose les resultats d'appreciation objective de la WFS par simulations et mesures experimentales. L'effet indesirable de la salle de reproduction sur les qualites objectives de la WFS fut illustre. Une premiere question de recherche fut ensuite abordee (chapitre 5), a savoir s'il est possible de reproduire des champs progressifs en salle dans un paradigme physique de controle actif: cette possibilite fut prouvee. L'approche technique privilegiee, "synthese de champs adaptative" ("Adaptive Wave Field Synthesis" [AWFS]), fut definie, puis simulee (chapitre 6). Cette approche d'AWFS comporte une originalite en controle actif et en reproduction de champs acoustiques: la fonction cout quadratique representant la minimisation des erreurs de reproduction inclut une regularisation de Tikhonov avec solution a priori qui vient de la WFS. L'etude de l'AWFS a l'aide de la decomposition en valeurs singulieres (chapitre 7) a permis de comprendre les mecanismes propres a l'AWFS. C'est la deuxieme principale originalite de la these. L'algorithme FXLMS (LMS et reference filtree) est modifie pour l'AWFS (chapitre 8). Le decouplage du systeme par decomposition en valeurs singulieres est illustre dans le domaine du traitement de signal et l'AWFS basee sur le controle independant des modes de rayonnement est simulee (chapitre 8). Ce qui constitue la troisieme originalite principale de cette these. Ces simulations du traitement de signal

    2006-11-01

    Full Text Available Depuis quelques années, dans l'élaboration de structures destinées à l'exploration et à l'exploitation des hydrocarbures en mer, le choix se porte parfois sur les structures en béton plutôt que sur les structures en acier, en particulier dans les zones difficiles de la mer du Nord. C'est pourquoi il nous a semblé intéressant de faire le point des connaissances actuelles sur le comportement du béton à l'eau de mer. Les problèmes les plus importants se situent au niveau de la zone de marnage, c'est-à-dire la zone où le béton est alternativement immergé. Ils sont de tous ordres : contraintes mécaniques avec érosion et cavitation, action capillaire de l'eau avec alternance d'humidification et de séchage, action du gel et du dégel. Les moyens de lutte ne manquent pas : constructions massives, voire surdimensionnées, résistant au choc, choix des formes, mise en aeuvre soignée d'un béton de qualité riche en ciment, correctement dosé en agrégats, dur, dense, compact, imperméable; introduction dans le béton d'un entraineur d'air pour diminuer les effets du gel. L'utilisation d'un ciment prise mer et le choix d'un rapport eau/ciment voisin de 0,45 sont hautement recommandés. Quant à la corrosion, elle concerne les structures en béton à tous les niveaux, aussi bien dans la zone immergée en continu que dans la zone alternativement immergée. L'attaque du béton par les sulfates contenus dans l'eau de mer conduit à la formation de sels de Candlot qui provoquent une dégradation du béton. Le remède consiste à limiter la teneur en aluminate tricalcique du ciment. L'attaque des aciers de renfort par les chlorures a fait l'objet de nombreuses études: la solution consiste surtout à protéger les aciers par galvanisation ou protection cathodique. D'une manière générale, le béton placé dans ce milieu agressif que constitue l'eau de mer subit des contraintes mécaniques et physicochimiques importantes, mais on sait en g

    2014-02-01

    A strong therapeutic alliance has been shown to improve mental health treatment outcomes in adults, but this topic has not been fully explored with youth. Adolescents, particularly justice-involved youth, stand to benefit greatly from an improved treatment experience. One quality which can improve treatment is mental health providers' interpersonal skills when attempting to build a therapeutic rapport with adolescent clients. Semi-structured interviews were conducted with 19 youth who screened positive for mental health concerns while in juvenile detention. Four themes were identified as important to improving the therapeutic alliance: Empathy, client-directed care, sequencing, and positive rapport. Suggestions for strengthening a therapeutic alliance are provided.

    2015-12-01

    Full Text Available Marie Darrieussecq, a contemporary French writer, had been accused of plagiarism several times during her career. Besides defending her reputation, these accusations forced her to think about her conceptions on fiction and writing. Finally, in Rapport de police, she succeeded in showing a mirror to the society of contemporary French writers, in which a tendency towards denying the legitimacy of fiction in certain cases can be observed. This phenomenon is diagnosed by Tiphaine Samoyault as the extension of the domain of plagiarism on simple particles of life. Behind this tendency resurges the old controversy of Plato and Aristotle on mimesis and fiction. Along with Jean-Marie Schaeffer’s analysis on the function of fiction from a cognitive point of view unfolds an apology for lecture and for a fictional writing that is capable of saying the inexpressible and speak for those who don’t have access to language.

    Cloud computing infrastructure is now widely used in many domains, but one area where there has been more limited adoption is research computing, in particular for running scientific high-performance computing (HPC) software. The Robust Application Porting for HPC in the Cloud (RAPPORT) project took advantage of existing links between computing researchers and application scientists in the fields of bioinformatics, high-energy physics (HEP) and digital humanities, to investigate running a set of scientific HPC applications from these domains on cloud infrastructure. In this paper, we focus on the bioinformatics and HEP domains, describing the applications and target cloud platforms. We conclude that, while there are many factors that need consideration, there is no fundamental impediment to the use of cloud infrastructure for running many types of HPC applications and, in some cases, there is potential for researchers to benefit significantly from the flexibility offered by cloud platforms.

  11. Eating Animals to Build Rapport: Conducting Research as Vegans or Vegetarians

    Directory of Open Access Journals (Sweden)

    Katie MacDonald

    2014-12-01

    Full Text Available Notions of hospitality, community, and the fostering of rapport and connection are foundational concerns for conducting research across difference. Drawing on methodological literature, this paper considers how access to various communities and “good” data is structured by the notion that in order to develop rapport researchers accept the “food”, specifically “meat” offered by their hosts. When researchers are vegetarians or vegans, this can entail a conflict in which questions of hospitality, relationships, and responsibility to ethical commitments come to the fore. As such, we analyze methodological literature in which the logic of nonhuman animal sacrifice is considered a means to the ends of research through the development of “rapport”—often coded as an ethical relationship of respect to the participant. We draw on experiences of veg*n researchers to explore how this assumption functions to position the consumption of meat as a necessary undertaking when conducting research, and in turn, denies nonhuman animal subjecthood. We interrogate the assumption that culture and communities are static inasmuch as this literature suggests ways to enter and exit spaces leaving minimal impact, and that posits participants will not trust researchers nor understand their decisions against eating nonhuman animals. We argue that because food consumption is figured as a private and individual choice, animals are not considered subjects in research. Thus, we articulate a means to consider vegan and/or vegetarians politics, not as a marker of difference, but as an attempt to engage in ethical relationships with nonhuman animals. In so doing, we call for the inclusion of nonhuman animals in relationships of hospitality, and thereby attempt to politicize the practice of food consumption while conducting research.

  16. Psychoacoustic Analysis of Synthesized Jet Noise

    An aircraft noise synthesis capability is being developed so the annoyance caused by proposed aircraft can be assessed during the design stage. To make synthesized signals as realistic as possible, high fidelity simulation is required for source (e.g., engine noise, airframe noise), propagation and receiver effects. This psychoacoustic study tests whether the jet noise component of synthesized aircraft engine noise can be made more realistic using a low frequency oscillator (LFO) technique to simulate fluctuations in level observed in recordings. Jet noise predictions are commonly made in the frequency domain based on models of time-averaged empirical data. The synthesis process involves conversion of the frequency domain prediction into an audible pressure time history. However, because the predictions are time-invariant, the synthesized sound lacks fluctuations observed in recordings. Such fluctuations are hypothesized to be perceptually important. To introduce time-varying characteristics into jet noise synthesis, a method has been developed that modulates measured or predicted 1/3-octave band levels with a (<20Hz) LFO. The LFO characteristics are determined through analysis of laboratory jet noise recordings. For the aft emission angle, results indicate that signals synthesized using a generic LFO are perceived as more similar to recordings than those using no LFO, and signals synthesized with an angle-specific LFO are more similar to recordings than those synthesized with a generic LFO.

    2017-10-27

    Participatory medicine and the availability of commercial technologies have given patients more options to view and track their health information and to communicate with their providers. This shift in the clinical process may be of particular importance in mental healthcare where rapport plays a significant role in the therapeutic process. In this review, we examined literature related to the impact of technology on the clinical workflow and patient-provider rapport in the mental health field between January 2014 and June 2017. Thirty three relevant articles, of 226 identified articles, were summarized. The use of technology clinically has evolved from making care more accessible and efficient to leveraging technology to improve care, communication, and patient-provider rapport. Evidence exists demonstrating that information and communication technologies may improve care by better connecting patients and providers and by improving patient-provider rapport, although further research is needed.

  19. Rapport Building and Instructional Fading Prior to Discrete Trial Instruction: Moving From Child-Led Play to Intensive Teaching.

    Shillingsburg, M Alice; Hansen, Bethany; Wright, Melinda

    2018-01-01

    Discrete trial instruction (DTI) is effective for teaching skills to children with autism spectrum disorder (ASD). Although effective, instructional settings can become aversive resulting in avoidant and escape-related behaviors. Given the significant social impairments associated with ASD, interventions that promote social approach and reduce avoidance are warranted. Rapport building or "pairing" the therapist and teaching setting with highly preferred activities prior to instruction can reduce problematic behaviors during subsequent instruction. However, the path from child-led play to DTI is not well established. Instructional fading may assist in bridging this gap. Four participants with ASD who were beginning an intensive behavioral intervention program were included in the current study. Participants progressed through nine stages of pairing and instructional fading with minimal problem behavior and high percentages of in-seat and close proximity to the therapist. Guidelines for incorporating rapport building strategies prior to intensive teaching with children with ASD are proposed.

    Full Text Available Le travail à domicile est une organisation ancienne. Il se décline dans une série d’activités salariées ou indépendantes, réalisées pour partie ou en totalité dans l’espace domestique. Le télétravail à domicile, basé sur l’utilisation de l’informatique et des technologies de l’information et de la communication, en représente un aspect moderne. Il redéfinit les frontières spatio-temporelles qui ont fortement structuré le monde du travail. Obligeant souvent à une forte implication, valorisé pour la liberté et la créativité, questionnant la séparation des sphères professionnelle et privée, le télétravail à domicile, lorsqu’il est pratiqué par des populations qualifiées et amatrices d’autonomie, peut être considéré comme emblématique des transformations contemporaines du rapport au travail et du rapport à l’emploi. Cette thématique mêle des enjeux transversaux et nous interroge sur l’évolution des modes de vie, sur de nouvelles figures de l’autorité et sur de nouvelles formes de recherche du bonheur au travail.Home work is an old type of organization. It corresponds to many activities which are salaried or independent and which are realized partially or entirely in domestic space. Home telework, using ICT, represents a modern form of home work. It changes space-time frontiers which have traditionally characterized work organization. It can require a strong implication, it can bring freedom and creativity, it questions the frontiers between work and non work: home telework, concerning qualified people who want autonomy, can be regarded as a symbol of contemporary transformations of work and employment. Theses themes question us about new ways of life, about the evolution of authority, and about happiness in working life.

  2. When students from different professions are co-located: the importance of interprofessional rapport for learning to work together.

    2015-01-01

    With increasing interest and research into interprofessional learning, there is scope to more deeply understand what happens when students from different professions live and study in the same location. This study aimed to explore the issue of co-location and its effects on how students learn to work with other professions. The setting for this study was a rural health education facility in Australia with close links to local health care and community services. Philosophical hermeneutics informed the research method. Interviews were undertaken with 29 participants, including students, academic educators and clinical supervisors in diagnostic radiography, medicine, nursing, nutrition and dietetics, pharmacy, physiotherapy, occupational therapy, and speech pathology. Photo-elicitation was used to facilitate participant engagement with the topic. The findings foreground the value of interprofessional rapport building opportunities for students learning to work together. Enabled by the proximity of different professions in shared educational, clinical and social spaces, interprofessional rapport building was contingent on contextual conditions (balance of professions, shared spaces and adequate time) and individual's interpersonal capabilities (being interested, being inclusive, developing interpersonal bonds, giving and receiving respect, bringing a sense of own profession and being patient-centred). In the absence of these conditions and capabilities, negative professional stereotypes may be inadvertently re-enforced. From these findings suggestions are made for nurturing interprofessional rapport building opportunities to enable students of different professions to learn to work together.

    Although age-related deficits in emotion perception have been established using photographs of individuals, the extension of these findings to dynamic displays and dyads is just beginning. Similarly, most eye-tracking research in the person perception literature, including those that study age differences, have focused on individual attributes gleaned from static images; to our knowledge, no previous research has considered cue use in dyadic judgments with eye-tracking. The current study employed a Brunswikian lens model analysis in conjunction with eye-tracking measurements to study age differences in the judgment of rapport, a social construct comprised of mutual attentiveness, positive feelings, and coordination between interacting partners. Judgment accuracy and cue utilization of younger (n = 47) and older (n = 46) adults were operationalized as correlations between a perceiver's judgments and criterion values within a set of 34 brief interaction videos in which 2 opposite sex college students discussed a controversial topic. No age differences emerged in the accuracy of judgments; however, pathways to accuracy differed by age: Younger adults' judgments relied on some behavioral cues more than older adults. In addition, eye-tracking analyses revealed that older adults spent more time looking at the bodies of the targets in the videos, whereas younger adults spent more time looking at the targets' heads. The contributions from both the lens model and eye-tracking findings provide distinct but complementary insights to our understanding of age-related continuities and shifts in social perceptual processing.

    The Alto project means the installation of an electron linear accelerator inside the experimental area of the tandem accelerator of the nuclear physics institute of Orsay (IPNO, France). This linear accelerator comes from CERN where it was operating as a pre-injector for LEP. This equipment will allow IPNO'teams to perform fast kinetics studies in a domain different from that of ELYSE accelerator. The time resolution will not be as high as that of ELYSE (picosecond) but will be sufficient (microsecond) to produce free radicals in aqueous and gaseous media. The main expectations of this installation can be classified according 3 axis: 1) basic research (mainly the study of nuclear matter through photo-fission, 2) research and development of accelerators (by providing a test bench for new high frequency systems and superconducting components), and 3) applied research for industry concerning: biochemistry under irradiation, radiation sensibility, DNA breaking, food and drug sterilization and behaviour of electronic components under irradiation. This rapport details the research program that could be achieved with this equipment, describes its contributions in terms of economic development, cooperation with industry, student training, and specifies the needed investment and the operating and maintenance costs.

    A method of synthesizing the phytosterol esters from oleic acid and sterols was studied, using immobilized lipase Candida sp. 99-125 as catalyst. Molar ratio (oleic acid/phytosterols), temperature, reaction period, organic solvents, catalyst, and silica-gel drier were optimized, and the result showed that 93.4% of the sterols had been esterified under the optimal synthetic condition: the molar ratio of oleic acid/phytosterol is 1:1 in 10 mL iso-octane, immobilized lipase (w, 140% of the sterols), incubated in an orbital shaker (200 rpm) at a temperature of 45 °C for 24 h. The immobilized lipase could be reused for at least 13 times with limited loss of esterification activity. The conversion still maintained up to 86.6%. Hence, this developed process for synthesizing phytosterol esters could be considered as simple and low-energy consumption compared to existing chemical processes.

    Full Text Available This paper presents a novel algorithm and architecture for digital frequency synthesis (DFS. It is based on a simple difference equation. Simulation results show that the proposed DFS algorithm is preferable to the conventional phase-locked-loop frequency synthesizer and the direct digital frequency synthesizer in terms of the spurious-free dynamic range (SFDR and the peak-signal-to-noise ratio (PSNR. Specifically, the results of SFDR and PSNR are more than 186.91 dBc and 127.74 dB, respectively. Moreover, an efficient DFS architecture for VLSI implementation is also proposed, which has the advantage of saving hardware cost and power consumption.

    Full Text Available The purpose of the present article was to assess the available literature concerning pain and autism. First, authors summarized the published articles on pain reactivity in people with autism. Second, the hypotheses envisaged to explain the presence of expressive particularities in people with autism spectrum disorders were reviewed; these included endogenous opioid excess theory, sensorial abnormalities and sociocommunicative deficit. Finally, the present review dealt with the tools available to assess and manage pain in people with autism. In conclusion, the authors revealed the need for more research to obtain more consensual data and provided some recommendations in this domain that were underexploited by the scientific community. From a clinical point of view, more knowledge about pain in people with autism should enable the development of specific assessment tools and, consequently, better pain management in daily care.

    [structures: see text] The total syntheses of the amaryllidaceae alkaloids haemanthidine, pretazettine, and tazettine as optically pure enantiomers are reported. Using D-mannose as the starting material, the critical relative stereochemical relationships are established with an intramolecular nitrone-alkene cycloaddition reaction. The synthetic route leads successively to (-)-haemanthidine and then to (+)-pretazettine and (+)-tazettine, taking advantage of the well-established complex relationships among these three alkaloids.

    Full Text Available Les sociétés contemporaines connaissent un accroissement des inégalités, en termes de richesse et d’accès au pouvoir. Le fait gestionnaire, par son emprise croissante, joue un rôle particulièrement important dans l’actualisation des rapports de domination. Il se situe, en effet, à l'articulation entre les décisions politiques majeures et les transformations des sphères d'activité sociale. Mais c'est aussi par le renouvellement permanent de ses différentes composantes que le fait gestionnaire agit : procédant par expérimentations successives, il assure ainsi la perpétuation de rapports de domination, au cœur même des sphères économiques et professionnelles. Pour montrer la pertinence de cette approche, l’article élabore, dans le prolongement des acquis de la sociologie du travail, un modèle pour analyser la volonté gestionnaire de changer. En appliquant ce modèle à un vaste éventail de contextes professionnels, nous pointons et expliquons les effets de polarisation sociale qu’engendre cette volonté.The constant change at the heart relations oh dominationContemporary societies are experiencing growing inequalities in wealth and access to power. The process of “managerialism”, by its increasing influence, plays a particularly important role in updating the relations of domination. It is, indeed, located at the joint between the major policy decisions and changes in social spheres. But this process acts also by the constant renewal of its various components: proceeding by successive experiments, it ensures the perpetuation of relations of domination, at the heart of economic and professional spheres. To show the relevance of this approach, the paper develops, following the achievements of the sociology of work, a model to analyze the managerial will of change. Applying this model to a wide range of advanced professional contexts, we point out and explain the effects of social polarization generated by this will

    Full Text Available Magnesioferrite is an important mineral due to its use in different scientific fields and by the fact that the soil through the action of weathering, can be a source of nutrients essential for plant development by the fact that in the soil. Its use in pure form or associated with other minerals is only possible through the synthesis in laboratory conditions. This study aimed to synthesize magnesioferrite and hematite from magnesian-magnetite by a co-precipitation procedure. The methodology used is an adaptation of the method of synthesis of pure magnetite, partially replacing the soluble salts of iron with soluble magnesium salts in the proportion of 30.0 mol% of Fe for Mg. The characterization of the synthetic minerals used x-rays diffraction, total chemical analysis and mass specific magnetic susceptibility. The results showed that besides the magnesian-magnetite an unprecedented muskoxita was synthesized, which upon annealing was converted to magnesioferrite and hematite and in the proportion of 93.1% and 6.9% respectively. The isomorphous substitution of Fe for Mg enhanced the thermal stability of the ferrimagnetic mineral synthesized.

Car, malgré des conceptions du vivant diamétralement opposées, Canguilhem et Kupiec se rejoignent sur l’idée que l’expérience vitale joue un rôle crucial – que ce soit en positif ou en négatif, comme un obstacle épistémologique ou comme un levier heuristique – dans l’apprentissage et la pratique de la biologie ou de la médecine.

    As professional case managers seek to improve outcomes, including the health status of their clients, it becomes imperative to gather and assess as much relevant information as possible to identify and address the client's needs in a holistic manner. Motivational interviewing is a highly effective technique case managers employ for this purpose. They also rely on it to move their clients toward a course of successful, desirable, and sustainable change, such as healthier diet, exercise, self-care, and adherence to medications regime and follow-up care. Across the case management spectrum, including hospitals, accountable care organizations, patient-centered medical homes, physician practices, clinics, and other settings in which case managers work with clients and their support systems. Motivational interviewing is a highly effective technique for gathering accurate and comprehensive information that is supportive of and additive to the assessment phase of the case management process. Using motivational interviewing, case managers can more readily uncover health and lifestyle needs of their clients. This results in building trusting relationships and developing rapport with clients, which can motivate them to move toward successful and desirable change. The design and implementation of a comprehensive and effective case management plan of care is facilitated by motivational interviewing, whereby professional case managers establish collaborative, respectful, trusting and individualized relationships with clients. Using the specific principles and techniques of motivational interviewing, case managers take a holistic approach to care to address a client's willingness and ability to change; addressing self-confidence and other emotional triggers that affect change and support the client's ability to embrace and sustain positive change.

    Full Text Available L'isomérisation des alcanes connaît un nouvel intérêt, depuis que la législation a prévu, par souci de protection de l'environnement, la suppression des alkyls de plomb dans les essences à l'horizon 1992. Cette réaction catalytique permet, en partant de n-paraffines de faible indice d'octane, issues du réformage catalytique ou de la distillation directe, d'obtenir des iso-paraffines présentant un indice d'octane beaucoup plus élevé. Elle est thermodynamiquement favorisée à basse température et nécessite par conséquent l'utilisation de catalyseurs développant une acidité importante. Deux types de catalyseurs sont actuellement utilisés industriellement : les catalyseurs à base de Pt sur lumine chlorée et les catalyseurs zéolithiques à base de Pt sur mordinite. Ces derniers sont considérés comme étant la nouvelle génération de catalyseurs. Ils présentent l'avantage d'être faciles à mettre en oeuvre et d'être beaucoup moins sensibles à la présence de poisons tels que soufre et eau dans la charge. Cependant ils conduisent à un gain d'octane considérablement plus faible que celui obtenu avec les catalyseurs Pt sur alumine chlorée. Cette étude bibliographique fait le point sur les différents mécanismes invoqués suivant le type de catalyseurs, les données cinétiques obtenues dans la littérature, et les différents procédés mis en oeuvre. Elle permet en particulier de mettre en évidence les contributions respectives des fonctions acides et métalliques pour l'isomérisation des alcanes de C4 à C7. En effet, il apparaît que suivant le type de catalyseurs utilisés, le mécanisme de la traction peut être bifonctionnel ou monofonctionnel acide. Dans certains cas, il pourrait même y avoir superposition des 2 mécanismes.

    A study of the electric and hydrophilic properties of poly allylamine (PAI) synthesized by plasma whose structure contains N-H, C-H, C-O and O-H bonds is presented, that promote the biocompatibility with the human body. To study the PAI hydrolytic affinity, solutions of salt concentration similar to those of the human body were used. The results indicate that the solutions modify the charge balance in the surfaces reducing the hydrophobicity in the poly allylamine whose contact angle oscillates among 10 and 16 degrees and the liquid-solid surface tension between 4 and 8 dina/cm.

    New patients are a particularly vulnerable population because they are at high risk of missing a subsequent visit or dropping out of care completely. However, few data exist on what new patients value in the beginning of a relationship with a new provider. Persons with HIV infection may be an ideal population to study the drivers of a positive initial patient-provider relationship, as it is a chronic and serious condition that requires a reliable, ongoing relationship with a provider. Informed by patients' real experiences, this study aims to identify what patients see as the most critical elements for building trust and rapport from the outset. We conducted longitudinal, in-person interviews with 21 patients new to the HIV clinic at the Michael E. DeBakey Veterans Affairs Medical Center in Houston, Texas, from August 2013 to March 2015. Patients were interviewed across three time points: once before their first provider visit, a second time within two weeks after the first visit, and a third time at 6 to 12 months after the first provider visit. We conducted 61 h of patient interviews. The mean age was 53 years; 52% were non-Hispanic white, 23% were non-Hispanic black and 19% were Hispanic. Patients described significant anxiety and vulnerability not just from HIV itself, but also in starting a relationship as a new patient to a new provider. Our analysis of these experiences revealed five actions providers can take to reduce their patients' anxiety and build trust early in the first visit: 1) provide reassurance to patients, 2) tell patients it's okay to ask questions, 3) show patients their lab results and explain what they mean, 4) avoid language and behaviors that are judgmental of patients, and 5) ask patients what they want [i.e., treatment goals and preferences]. Our study incorporates direct input from patients and highlights the unique psychological challenges that patients face in seeking care from a new provider. The actionable opportunities cited by

    It is suggested that "schizophrenic color", as the impression of schizophrenic disturbance of rapport, is closely related to the disturbance of communication, especially metacommunication, by many researchers. So the author defined a symptom named "the cognitive schema of others' position", which means others' time-space position in a patient's delusional world, as the symptom being expected to be closely related to the disturbance of the patient's metacommunication at the interaction with others in his delusional world. Then the author examined statistically the relationship of "schizophrenic color" (or the operational diagnosis of schizophrenia according to DSM-III) to "the cognitive schema of others' position" and at the same time to several forms of auditory hallucination having been considered to be significantly related to schizophrenia. 58 hallucinatory-delusional states (29 schizophrenia, 29 non-schizophrenia) were actually examined and some results were pointed out as follows. Observation of the "improper cognitive schema of others' position", which means the fantastic and impossible, for a human being, time-space position of others in a patient's delusional world, was statistically related to the deterioration of "schizophrenic color" or the operational diagnosis of schizophrenia according to DSM-III. This result was considered to be related to the supposition that the "improper cognitive schema of others' position" is a symptom representing the schizophrenic collapse of the cognitive time-space construction as well as the schizophrenic disturbance of metacommunication. Otherwise, the observation of hallucinatory voices speaking and answering directly to the patient, which has been expected to be one of the most important symptoms of schizophrenia, was not statistically related to the deterioration of "schizophrenic color" or the operational diagnosis of schizophrenia according to DSM-III. And the observation of hallucinatory voices arguing about the

    In the present scenario, there are growing concerns over the potential impacts of bioengineered nanoparticles in the health sector. However, our understanding of how bioengineered nanoparticles may affect organisms within natural ecosystems, lags far behind our rapidly increasing ability to engineer novel nanoparticles. To date, research on the biological impacts of bioengineered nanoparticles has primarily consisted of controlled lab studies of model organisms with single species in culture media. Here, we described a cost effective and environment friendly technique for green synthesis of silver nanoparticles. Silver nanoparticles were successfully synthesized from 1 mM AgNO 3 via a green synthesis process using leaf extract as reducing as well as capping agent. Nanoparticles were characterized with the help of UV–vis absorption spectroscopy, X-ray diffraction and TEM analysis which revealed the size of nanoparticles of 30-40 nm size. Further the nanoparticles synthesized by green route are found highly toxic against pathogenic bacteria and plant pathogenic fungi viz. Escherichia coli, Pseudomonas syringae and Sclerotiniasclerotiorum. The most important outcome of this work will be the development of value-added products and protection of human health from pathogens viz., bacteria, virus, fungi etc.

  1. Squid Giant Axons Synthesize NF Proteins.

    Crispino, Marianna; Chun, Jong Tai; Giuditta, Antonio

    2018-04-01

    Squid giant axon has been an excellent model system for studying fundamental topics in neurobiology such as neuronal signaling. It has been also useful in addressing the questions of local protein synthesis in the axons. Incubation of isolated squid giant axons with [ 35 S]methionine followed by immunoprecipitation with a rabbit antibody against all squid neurofilament (NF) proteins demonstrates the local synthesis of a major 180 kDa NF protein and of several NF proteins of lower molecular weights. Their identification as NF proteins is based on their absence in the preimmune precipitates. Immunoprecipitates washed with more stringent buffers confirmed these results. Our data are at variance with a recent study based on the same experimental procedure that failed to visualize the local synthesis of NF proteins by the giant axon and thereby suggested their exclusive derivation from nerve cell bodies (as reported by Gainer et al. in Cell Mol Neurobiol 37:475-486, 2017). By reviewing the pertinent literature, we confute the claims that mRNA translation is absent in mature axons because of a putative translation block and that most proteins of mature axons are synthesized in the surrounding glial cells. Given the intrinsic axonal capacity to synthesize proteins, we stress the glial derivation of axonal and presynaptic RNAs and the related proposal that these neuronal domains are endowed with largely independent gene expression systems (as reported by Giuditta et al. in Physiol Rev 88:515-555, 2008).

    2014-09-01

    Full Text Available Chemoenzymatic peptide synthesis is the hydrolase-catalyzed stereoselective formation of peptide bonds. It is a clean and mild procedure, unlike conventional chemical synthesis, which involves complicated and laborious protection-deprotection procedures and harsh reaction conditions. The chemoenzymatic approach has been utilized for several decades because determining the optimal conditions for conventional synthesis is often time-consuming. The synthesis of poly- and oligopeptides comprising various amino acids longer than a dipeptide continues to pose a challenge owing to the lack of knowledge about enzymatic mechanisms and owing to difficulty in optimizing the pH, temperature, and other reaction conditions. These drawbacks limit the applications of the chemoenzymatic approach. Recently, a variety of enzymes and substrates produced using recombinant techniques, substrate mimetics, and optimal reaction conditions (e.g., frozen aqueous media and ionic liquids have broadened the scope of chemoenzymatic peptide syntheses. In this review, we highlight the recent advances in the chemoenzymatic syntheses of various peptides and their use in developing new materials and biomedical applications.

    As patients become increasingly involved in their medical care, physician-patient communication gains importance. A previous study showed that physician self-disclosure (SD) of personal information by primary care providers decreased patient rating of the provider communication skills. The objective of this study was to explore the incidence and impact of emergency department (ED) provider self-disclosure on patients' rating of provider communication skills. A survey was administered to 520 adult patients or parents of pediatric patients in a large tertiary care ED during the summer of 2014. The instrument asked patients whether the provider self-disclosed and subsequently asked patients to rate providers' communication skills. We compared patients' ratings of communication measurements between encounters where self-disclosure occurred to those where it did not. Patients reported provider SD in 18.9% of interactions. Provider SD was associated with more positive patient perception of provider communication skills (pself-disclosure (47.1%). Patients reported that they would like to hear about their providers' experiences with a similar chief complaint (64.4% of patients), their providers' education (49%), family (33%), personal life (21%) or an injury/ailment unlike their own (18%). Patients responded that providers self-disclose to make patients comfortable/at ease and to build rapport. Provider self-disclosure in the ED is common and is associated with higher ratings of provider communication, rapport, and patient satisfaction.

    2016-01-01

    In one dimensional systems, it is possible to create periodic structures in phase space through driving, which is called phase space crystals (Guo et al 2013 Phys. Rev. Lett. 111 205303). This is possible even if for particles trapped in a potential without periodicity. In this paper we discuss ultracold atoms in a driven optical lattice, which is a realization of such a phase space crystals. The corresponding lattice structure in phase space is complex and contains rich physics. A phase space lattice differs fundamentally from a lattice in real space, because its coordinate system, i.e., phase space, has a noncommutative geometry, which naturally provides an artificial gauge (magnetic) field. We study the behavior of the quasienergy band structure and investigate the dissipative dynamics. Synthesizing lattice structures in phase space provides a new platform to simulate the condensed matter phenomena and study the intriguing phenomena of driven systems far away from equilibrium.

    2006-01-01

    Sorption of inorganic mercury (Hg 2+ ) and methyl mercury, on chemically synthesized polyaniline, in 0.1-10N HCl solutions has been studied. Hg 2+ is strongly sorbed at low acidities and the extent of sorption decreases with increase in acidity. The sorption of methyl mercury is very low in the HCl concentration range studied. Sorption of Hg 2+ on polyaniline in 0.1-10N LiCl and H 2 SO 4 solutions has also been studied. The analysis of the data indicates that the sorption of Hg 2+ depends on the degree of protonation of polyaniline and the nature of mercury(II) chloride complexes in solution. X-ray photoelectron spectroscopy analysis (XPS) of polyaniline sorbed with mercury show that mercury is bound as Hg 2+ . Sorbed mercury is quantitatively eluted from polyaniline with 0.5N HNO 3 . Polyaniline can be used for separation and pre-concentration of inorganic mercury from aqueous samples. (author)

    Ammonium rare earth fluorides NH(sub 4)Ln(sub 3)F(sub 10) (Ln=Dy, Ho, Y, Er, Tm) were synthesized by a hydrothermal method. Two polymorphs, of the hexagonal(beta)-KYb(sub 3)F(sub 10) and the cubic(gamma)-KYb(sub 3)F(sub 10) structure types, were formed under hydrothermal conditions for most of the rare earth fluorides except NH(sub 4)Dy(sub 3)F(sub 10), for which only the cubic -phase was obtained. The crystal structures of MLn(sub 3)F(sub 10) (M=alkaline metal, NH(sup+4) and Ln=rare earth) show a strong correlation to the ratio of ionic radii (R(sub M)/R(sub Ln)), which has been expressed in a structure phase diagram of the ionic radii of univalent and rare earth cations

    The supply-Technical Advisory Task Force-Synthesized Gaseous Hydrocarbon Fuels considered coal, hydrocarbon liquids, oil shales, tar sands, and bioconvertible materials as potential feedstocks for gaseous fuels. Current status of process technology for each feedstock was reviewed, economic evaluations including sensitivity analysis were made, and constraints for establishment of a synthesized gaseous hydrocarbon fuels industry considered. Process technology is presently available to manufacture gaseous hydrocarbon fuels from each of the feedstocks. In 1975 there were eleven liquid feedstock SNG plants in the United States having a capacity of 1.1 billion SCFD. There can be no contribution of SNG before 1982 from plants using feedstocks other than liquids because there are no plants in operation or under construction as of 1977. Costs for SNG are higher than current regulated prices for U.S. natural gas. Because of large reserves, coal is a prime feedstock candidate although there are major constraints in the area of coal leases, mining and water permits, and others. Commercial technology is available and several new gasification processes are under development. Oil shale is also a feedstock in large supply and commercial process technology is available. There are siting and permit constraints, and water availability may limit the ultimate size of an oil shale processing industry. Under projected conditions, bioconvertible materials are not expected to support the production of large quantities of pipeline quality gas during the next decade. Production of low or medium Btu gas from municipal solid wastes can be expected to be developed in urban areas in conjunction with savings in disposal costs. In the economic evaluations presented, the most significant factor for liquid feedstock plants is the anticipated cost of feedstock and fuel. The economic viability of plants using other feedstocks is primarily dependent upon capital requirements.

    The result of this work, seeks to be a contribution for the treatment of radioactive wastes, with base to the sorption properties that present those porous oxides, synthesized by a method that allows to increase the sorption capacity. The main objective of the present investigation has been the modification of the structural characteristics of the oxides of Fe, Mg and Zn to increase its capacity of sorption of 60 Co in particular. It was studied the effect of the synthesis method by combustion in the inorganic oxides; the obtained solids were characterized using the following techniques: X-ray diffraction (XRD), scanning electron microscopy (SEM), semiquantitative elementary analysis by Dispersive energy spectroscopy (EDS) and determination of surface area by the Brunauner-Emmett-Teller method (BET). Also was carried out batch type experiments for the sorption of Co 2+ , with the purpose of studying the sorption capacity of each one of the prepared oxides. In accordance with that previously exposed, the working plan that was carried out in this investigation is summarized in the following stages: 1. Preparation of inorganic oxides by two different methods, studying the effect of the temperature in the synthesis process. 2. Characterization of the inorganic oxides by XRD, by means of which those were chosen the solids with better properties. 3. Characterization of the inorganic oxides by SEM and EDS where it was studied the morphology of the synthesized materials and the semiquantitative elemental composition. 4. Realization of a sorption experiment type Batch with non radioactive Co 2+ to simulate the sorption of 60 Co and determination of the sorption capacity by means of neutron activation of the non radioactive cobalt. 5. Determination of the surface area by the (BET) technique of the inorganic oxides with better sorption properties. (Author)

  13. Synthesizing Earth's geochemical data for hydrogeochemical analysis

    For over 200 years, geochemical, microbiological, and chemical data have been collected to describe the evolution of the surface earth. Many of these measurements are data showing variations in time or in space. To forward predict hydrologic response to changing tectonic, climatic, or anthropogenic forcings requires synthesis of these data and utilization in hydrogeochemical models. Increasingly, scientists are attempting to synthesize such data in order to make predictions for new regions or for future time periods. However, to make such complex geochemical data accessible requires development of sophisticated cyberinfrastructures that both invite uploading as well as usage of data. Two such cyberinfrastructure (CI) initiatives are currently developing, one to invite and promote the use of environmental kinetics data (laboratory time course data) through ChemxSeer, and the other to invite and promote the use of spatially indexed geochemical data for the Earth's Critical Zone through CZEN.org. The vision of these CI initiatives is to provide cyber-enhanced portals that encourage domain scientists to upload their data before publication (in private cyberspace), and to make these data eventually publicly accessible (after an embargo period). If the CI can be made to provide services to the domain specialist - e.g. to provide data analysis services or data comparison services - we envision that scientists will upload data. In addition, the CI can promote the use and comparison of datasets across disciplines. For example, the CI can facilitate the use of spatially indexed geochemical data by scientists more accustomed to dealing with time-course data for hydrologic flow, and can provide user-friendly interfaces with CI established to facilitate the use of hydrologic data. Examples of the usage of synthesized data to predict soil development over the last 13ky and its effects on active hydrological flow boundaries in surficial systems will be discussed for i) a N

  18. Mechanochemically Driven Syntheses of Boride Nanomaterials

    Blair, Richard G.

    Solid state metathesis reactions have proven to be a viable route to the production of unfunctionalized nanomaterials. However, current implementations of this approach are limited to self-propagating reactions. We have been investigating mechanically driven metathesis reactions. The use of high-energy ball mills allows control of crystallite sizes without the use of a capping group. Reinforcement materials with crystallite sizes on the order of 5-30 nm can be produced in such a manner. Borides are of particular interest due to their strength, high melting point, and electrical conductivity. The ultimate goal of this work is to prepare oxide and capping group-free nanoparticles suitable for incorporation in thermoelectric, polymer, and ceramic composites. Ultimately this work will facilitate the production of improved thermoelectric materials that will provide robust, deployable, power generation modules to supplement or replace fuel cell, Stirling, and battery-derived power sources. It will also result in scalable, bulk syntheses of tough, refractory, conductive nanomaterials for polymer composites with improved electrical properties, ceramic composites with enhanced fracture toughness, and composites with enhanced neutron reflectance and/or absorbance.

    Full Text Available Sugar-based surfactants were obtained in good yields (up to 100% under mild conditions (70°C, methanol or mixtures of methanol and water by ring-opening of terminal epoxides with aminopolyols, derived from glucose. Reaction of N-methyl glucamine with epoxides from even-numbered C4-C18 alpha-olefins or from terminal unsaturated fatty acid methyl esters leads to linear products, while corresponding reactions with N-dodecyl glucamine or glucamine yield surfactants with different Y-structures. Products obtained by conversion of omega-epoxy fatty acid methyl esters were saponificated with NaOH or hydrolyzed enzymatically to sodium salts or free acids respectively, which are amphoteric surfactants. Studies of the surfactants at different pH-values demonstrate different surface active properties in aqueous solutions. Critical micelle concentrations (c.m.c. in a range between 2 and 500mg/l and surface tensions of 25-40mN/m were measured for several of the synthesized sugar-based surfactants. The ring-opening products are rather poor foamers, whereas some of the corresponding hydrobromides show good foaming properties.

    The text entitled "Femicides in ethnic and racialized groups: syntheses" presents some of the discussions that took place during a seminar on this topic in Buenaventura. Buenaventura is the main Colombian port on the Pacific, a region rich in minerals and a corridor for the movement of goods, which makes it a strategic territory and a center for disputes. At the seminar, the social and political determinants of femicide were discussed, understanding it as a tactic of waging war against women. The forum provided a space for academic discussion, but also for grievances over inter-personal violence, the manifestation of feelings and the elaboration of pain and grief through the medium of art. We believe that the dissemination of this experience to the Brazilian public, in a country with ethnic, social and racial vulnerability similar to that in Colombia, will be of value to social and health workers. The scope of this paper is therefore to provide the opinion of its authors on the determinants of femicides and on actions to tackle them, in addition to a synthesis of the discussions and debates that permeated the event.

  1. Feedback Synthesizes Neural Codes for Motion.

    In senses as diverse as vision, hearing, touch, and the electrosense, sensory neurons receive bottom-up input from the environment, as well as top-down input from feedback loops involving higher brain regions [1-4]. Through connectivity with local inhibitory interneurons, these feedback loops can exert both positive and negative control over fundamental aspects of neural coding, including bursting [5, 6] and synchronous population activity [7, 8]. Here we show that a prominent midbrain feedback loop synthesizes a neural code for motion reversal in the hindbrain electrosensory ON- and OFF-type pyramidal cells. This top-down mechanism generates an accurate bidirectional encoding of object position, despite the inability of the electrosensory afferents to generate a consistent bottom-up representation [9, 10]. The net positive activity of this midbrain feedback is additionally regulated through a hindbrain feedback loop, which reduces stimulus-induced bursting and also dampens the ON and OFF cell responses to interfering sensory input [11]. We demonstrate that synthesis of motion representations and cancellation of distracting signals are mediated simultaneously by feedback, satisfying an accepted definition of spatial attention [12]. The balance of excitatory and inhibitory feedback establishes a "focal" distance for optimized neural coding, whose connection to a classic motion-tracking behavior provides new insight into the computational roles of feedback and active dendrites in spatial localization [13, 14].

    Accurate data on young people's sexual behaviour and sexual health practice is essential to inform effective interventions and policy. However, little empirical evidence exists to support methodological design decisions in projects assessing young people's sexual health, especially in African contexts. This short report uses original empirical data collected in Ghana in 2012 to assess the effects of data collection mode and interviewer gender on young people's reporting of sexual health and access to supportive sexual health resources. The findings indicate that the effect of data collection mode may vary by gender, and there is no indication of an interviewer gender effect for males in this study. Preliminary results suggest that building strong rapport with research participants in this context may lead to reduced sexual health data quality. These findings merit further investigation and have direct implications for the design of projects measuring sexual health and related variables in Ghana.

  4. Study of photoconductor polymers synthesized by plasma

    2007-01-01

    In this work the photoconductivity in poly thiophene (PTh), poly pyrrole (PPy) and doped poly pyrrole with iodine (PPy/I) is studied, whose structures depend of the intensity of the electric field applied during the synthesis by plasma. The conjugated organic polymers possess double alternated bonds in its chemical structure that its allow the one movement of π electrons through the polymeric chains. The plasma is produced by means of splendor discharges to 13.5 MHz, resistive coupling, at one pressure that oscillates in the interval from 2 to 3x10 -1 mbar, 180 min and powers of 10, 24, 40, 60 , 80 and 100 W. Its were used heteroaromatic polymers like PTh and PPy/I, due to their potential applications in optoelectronics. The influence of the iodine is evaluated as dopant in PPy and it is compared with their similar one without doping in the light absorption/emission processes. The polymers synthesized by plasma can ramify or to intersect due to the energy applied during the synthesis. However, if the polymer intersects, the aromaticity can continue through the polymeric chains. The absorptions obtained by infrared spectroscopy, suggest that the polymer conserves the aromatic structure of the monomer fundamentally with substitutions that indicate inter crossing and partial fragmentation. The structure of most of the polymers spreads to be amorphous because they don't possess any classification. However, the PPy/I and PTh synthesized by this technique present crystalline segments whose intensity diminishes with the power of the discharge. In PTh, the average crystallinity diminishes from 19.8% to 9.9%, and in PPy/I of 15.9% to 13.3% in the interval of 10 to 100 W of power. In this work, however, its were crystalline arrangements in all the studied powers. The classification of the polymeric structure favors the formation of trajectories of transfer of electric loads among the chains, that which influences in the global electric conductivity of the material.

    The mission and challenge of the Intergovernmental panel on climate change (IPCC, GIEC in French) is to evaluate, synthesize and make available the sum of scientific and economic information of the complex domain of climatic change, and in addition to make the results of these works accepted by government representatives of 192 states. This document makes a brief synthesis in three parts of the 4. assessment report of the IPCC: 1 - physical scientific bases of climatic change: characteristic of the phenomenon, greenhouse gas emissions trend, already observed effects, forecasts of climate models; 2 - impacts, adaptations and vulnerabilities of climatic change: types of future impacts, impacts per sector, regional impacts, limits of ecosystems adaptation; 3 - mitigation of climatic changes: past emissions and future trends, possible mitigation actions and cost, possible political levers for emissions abatement. A last part introduces the French researchers involved in IPCC's works. (J.S.)

  6. Neurofilament proteins are synthesized in nerve endings from squid brain.

    It is generally believed that the proteins of the nerve endings are synthesized on perikaryal polysomes and are eventually delivered to the presynaptic domain by axoplasmic flow. At variance with this view, we have reported previously that a synaptosomal fraction from squid brain actively synthesizes proteins whose electrophoretic profile differs substantially from that of the proteins made in nerve cell bodies, axons, or glial cells, i.e., by the possible contaminants of the synaptosomal fraction. Using western analyses and immunoabsorption methods, we report now that (a) the translation products of the squid synaptosomal fraction include neurofilament (NF) proteins and (b) the electrophoretic pattern of the synaptosomal newly synthesized NF proteins is drastically different from that of the NF proteins synthesized by nerve cell bodies. The latter results exclude the possibility that NF proteins synthesized by the synaptosomal fraction originate in fragments of nerve cell bodies possibly contaminating the synaptosomal fraction. They rather indicate that in squid brain, nerve terminals synthesize NF proteins.

    Positron emission tomography (PET) offers the highest resolution of all nuclear medicine imaging modalities and allows quantitation of tracer concentration in tissues. For more than 60 years, some of C-11 or F-18 labeled amino acids have been synthesized and evaluated for potential use in oncology, neurology and psychiatric disorders. Besides, a variety of radioisotope labeled amino acids have proven to be useful for imaging tumors, especially for brain tumor, lung tumor and breast tumor. These amino acids can be subdivided into two categories. The first category is represented by radiolabled naturally occurring amino acids and structurally similar analogues. Although these radiolabeled amino acids have proven useful in detecting brain and systemic tumors, it is susceptible to in vivo metabolism through multiple pathways that give rise to numerous radiolabled metabolites. On the other side, structurally similar amino acid analogues have some significant advantages over the natural amino acids. These nonnatural amino acids are not metabolized, which simplifieds the kinetic analysis of their uptake. On the basis of the promising results obtained with these nonnatural amino acids in preclinical studies, recent efforts have focused on the development of new F-18 labeled nonnatural amino acids. Recently, O-(2-[ 18 F]Fluoroethyl)-L-tyrosine (FET), O-(3-[ 18 F]Fluoropropyl)-L-tyrosine (FPT) were developed and evaluated among structurally similar to a new amino acid analogue. FET has shown high uptake in activated inflammatory cells using an experimental acute abscess model and in inflammation within lymph nodes. FPT was superior to FDG and had a slight advantage over FET in the differentiation of tumor from inflammation, and, like FET, it appeared to be a potential amino acid tracer for tumor imaging with PET. In this paper, we elected to introduce fluoroethyl and fluoropropyl groups at the R 1 positions and OCH 3 at R 2 position to the same effect of FET. Herein, we wish

    The increasing attention for restoration of buildings of historical and architectural importance has increased the interest for lime-based binders, which could be applied for manufacturing repair mortars and plasters compatible with historical heritage. Different additives, admixtures or fibers may be incorporated to improve mechanical and thermal features of such materials. In this study synthesized aluminosilicates (SA) were applied as an additive for lime mortar. The technology of synthesis consisted in the deposition of aluminosilicates from a sodium liquid glass by the aluminum sulphate Al2(SO4)3. The goal of this investigation was developing a new method of aluminosilicates synthesis from a sodium liquid glass and using this new material as a component for a lime mortar. Aluminosilicates were precipitated from the solution of aluminum sulphate Al2(SO)3 and sodium silicate. SA were then used as an additive to calcareous compositions and their influence was tested. Mortars were prepared with commercial air lime and siliceous river sand. Air lime binder was replaced by 5 and 10 wt.% of SA. Calcareous composition specimens were formed at water/lime ratio 1.0. The following analyses were made: grain size distribution of SA, X-ray diffraction analysis (XRD), sorption properties, plastic strength and compressive strength of lime mortars. XRD pattern of the SA shows the presence of thenardite, gibbsite and amorphous phase represented by aggregate of nano-size cristobalite-like crystallites. Application of SA leads to increase of compressive strength after 90 days of hardening by 28% and 53% at SA content 5 and 10% respectively comparing to specimens without this additive. Contents of chemically bound lime in the reference specimens after 28 days of hardening in air-dry conditions was 46.5%, while in specimens modified with SA contained 50.0-55.3% of bound lime depending on filtrate pH. This testifies to high activity of calcareous composition. The new blended lime

    The synthesis of decamethylmanganocene [(eta-C 5 (CH 3 ) 5 ) 2 Mn or (Me 5 Cp) 2 Mn)] is described. Magnetic susceptibility and electron paramagnetic resonance (EPR) studies show that (Me 5 Cp) 2 Mn is a low-spin, 17-electron compound with an orbitally degenerate, 2 E/sub 2g/ [e/sub 2g/ 3 a/sub 1g/ 2 ] ground state. An x-ray crystallographic study of (Me 5 Cp) 2 Mn shows that it is a monomeric, D/sub 5d/ decamethylmetallocene with metal to ring carbon distances that are about 0.3 A shorter than those determined for high-spin manganocenes. The syntheses of new (Me 5 Cp) 2 M (M = Mg,V,Cr,Co, and Ni) and [(Me 5 Cp) 2 M]PF 6 (M = Cr,Co, and Ni) compounds are described. In addition, a preparative route to a novel, dicationic decamethylmetallocene, [(Me 5 Cp) 2 Ni](PF 6 ) 2 is reported. Infrared, nuclear magnetic resonance, magnetic susceptibility, and/or x-ray crystallographic studies indicate that all the above compounds are D/sub 5d/ or D/sub 5h/ decamethylmetallocenes with low-spin electronic configurations. Cyclic voltammetry studies verify the reversibility and the one-electron nature of the (Me 5 Cp) 2 M → [(Me 5 Cp) 2 M] + (M = Cr,Mn,Fe,Co,Ni), [(Me 5 Cp) 2 Mn] - → (Me 5 Cp) 2 Mn and [(Me 5 Cp) 2 Ni] + → [Me 5 Cp) 2 Ni] 2+ redox reactions. These studies reveal that the neutral decamethylmetallocenes are much more easily oxidized than their metallocene counterparts. This result attests to the electron-donating properties of the ten substituent methyl groups. Proton and carbon-13 NMR data are reported for the diamagnetic Mg(II), Mn(I), Fe(II), Co(III), and Ni(IV) decamethylmetallocenes and for [(Me 5 Cp) 2 V(CO) 2 ] + .

    ,1-phenylene)bismaleimide (MDPB). It showed the same healing ability as 2MEP4F while all starting materials are cheaper and commercially available. To further improve the mechanical strength of the PFA-MDPB healable polymer, epoxy as a strengthening component was mixed with PFA-MDPB healable polymer. The PFA, MDPB and epoxy composite polymers were further reinforced by carbon fiber as done with 2MEP4F matrix and the final composites were proved to have higher short beam shear strength than 2MEP4F while exhibiting a similar healing efficiency. Healable polymer MDPB (a two maleimide groups monomer) -- FGEEDR (a four furan groups monomer) was also designed and synthesized for transparent healable polymer. The MDPB-FGEEDR healable polymer was composited with silver nanowires (AgNWs) to afford healable transparent composite conductor. Razer blade cuts in the composite conductor could heal upon heating to recover the mechanical strength and electrical conductivity of the composite. The healing could be repeated for multiple times on the same cut location. The healing process was as fast as 3 minutes for conductivity to recover 97% of the original value. For electroactive polymer polypyrrole, the fast volume change upon electrical field change due to electrochemical oxidization or reduction was studied for actuation targeting toward a robotic application. The flexibility of polypyrrole was improved via copolymerization with pyrrole derivatives. Actuator devices are fabricated that more suitable for implantable medical device application than pyrrole homopolymer. The change of dipole re-orientation and thus dielectric constant of ferroelectric polymers and ceramics upon electrical field may be exploited for electrocaloric effect (ECE) and solid state refrigeration. For ferroelectric ceramics, we synthesized a series of Ba1-xSrxTiO3 nanoparticles with diameter ranging from 8-12 nm and characterized their dielectric and ferroelectric properties through hysteresis measurement.

    2011-05-01

    Full Text Available Je m’interroge dans cet article sur les implications du principe libertarien de la pleine propriété de soi sur la question du rapport moral à soi-même. À travers le principe de la pleine propriété de soi, les libertariens défendent la liberté entière de chacun de vivre comme il l���entend, pourvu que les droits des autres soient respectés. Apparemment, ce principe n’a pas grand-chose à nous dire sur ce que nous sommes moralement autorisés à nous faire à nous-mêmes ou non. Certains libertariens, comme Vallentyne, soutiennent toutefois que le principe de la pleine propriété de soi est incompatible avec l’existence de devoirs envers soi. La pleine propriété de soi impliquerait l’indifférence morale du rapport à soi. Je soutiens dans cet article que le principe de la pleine propriété de soi n’implique pas que ce que nous nous faisons à nous-mêmes soit moralement indifférent. Je veux aussi montrer que même si les libertariens, et en particulier Vallentyne, soutiennent la thèse de l’indifférence morale du rapport à soi, celle-ci n’est pas liée à la thèse de la pleine propriété de soi, mais bien plutôt à leur subjectivisme moral.ABSTRACTI ask in this article what the libertarian principle of full self-ownership has to say about volontary actions directed towards oneself. Through the principle of full self-ownership, libertarians defend the persons’ individual liberty to live as they choose to do, as long as they don’t infringe on the rights of others. Apparently, this principle doesn’t have much to say about what we are morally allowed to do to ourselves or not. Some libertarians, however, like Vallentyne, maintain that, if we have duties or obligations to ourselves, then we cannot be full self-owner. In this perspective, full self-ownership would imply that what we do to ourselves is morally indifferent. I want to show in this article that full self-ownership is compatible with the

    2017-06-01

    To investigate associations between ratings of "thin slices" from recorded clinic visits and perceived patient-centeredness; to compare ratings from video recordings (sound and images) versus audio recordings (sound only). We analyzed 133 video-recorded primary care visits and patient perceptions of patient-centeredness. Observers rated thirty-second thin slices on variables assessing patient affect, physician affect, and patient-physician rapport. Video and audio ratings were collected independently. In multivariable analyses, ratings of physician positive affect (but not patient positive affect) were significantly positively associated with perceived patient-centeredness using both video and audio thin slices. Patient-physician rapport was significantly positively associated with perceived patient-centeredness using audio, but not video thin slices. Ratings from video and audio thin slices were highly correlated and had similar underlying factor structures. Physician (but not patient) positive affect is significantly associated with perceptions of patient-centeredness and can be measured reliably using either video or audio thin slices. Additional studies are needed to determine whether ratings of patient-physician rapport are associated with perceived patient-centeredness. Observer ratings of physician positive affect have a meaningful positive association with patients' perceptions of patient-centeredness. Patients appear to be highly attuned to physician positive affect during patient-physician interactions. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  6. Reflecting on the PRET A Rapporter Framework Via a Field Study of Adolescents? Perceptions of Technology and Exercise

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available PRET A Rapporter (PRETAR was developed to explicitly structure user-centered evaluation studies to ensure all necessary elements are individually and independently considered. Its creators see its benefit as twofold: for study design and in retrospective evaluations. We evaluate PRETAR’s potential by applying it retrospectively to one of our eHealth field studies in which we investigated the design requirements for mobile technologies that would support and motivate adolescents to exercise opportunistically. We also use PRETAR to evaluate the key literature for this eHealth study. This shows that typically the research methodology is under-reported. Then we document the study in terms of its purpose, resources, ethical concerns, data collection and analysis techniques, and manner of reporting the study. Finally, our reflection on the use of PRETAR leads us to propose that four different modes of the framework should be applied during the course of a study, that is, when reviewing, planning, conducting, and discussing.

    An overview of the deep geothermal project in Lavey, Switzerland is presented. The site is located near the Rhone river, where this river crosses a mountain chain in the Alps. The geology of the region is described. A well known spa is located in Lavey. The aim of the project is to generate power and deliver heat to a local district heating. Two wells should be bored to capture underground water at an appropriate temperature. The present report summarises the previous studies and focuses on the technical and financial feasibility of the future cogeneration plant. In particular, it presents the foreseen installations and the potential heat users. The costs are estimated in several possible boring scenarios. The most promising strategy is similar to that adopted decades ago in the Austrian spa of Bad Blumau. It combines geothermal energy and biomass. A business plan is presented. Recommendations for the next steps are given.

    To assess the quality of synthesized voices through listeners' skills in discriminating human and synthesized voices. Prospective study. Eighteen human voices with different types and degrees of deviation (roughness, breathiness, and strain, with three degrees of deviation: mild, moderate, and severe) were selected by three voice specialists. Synthesized samples with the same deviations of human voices were produced by the VoiceSim system. The manipulated parameters were vocal frequency perturbation (roughness), additive noise (breathiness), increasing tension, subglottal pressure, and decreasing vocal folds separation (strain). Two hundred sixty-nine listeners were divided in three groups: voice specialist speech language pathologists (V-SLPs), general clinician SLPs (G-SLPs), and naive listeners (NLs). The SLP listeners also indicated the type and degree of deviation. The listeners misclassified 39.3% of the voices, both synthesized (42.3%) and human (36.4%) samples (P = 0.001). V-SLPs presented the lowest error percentage considering the voice nature (34.6%); G-SLPs and NLs identified almost half of the synthesized samples as human (46.9%, 45.6%). The male voices were more susceptible for misidentification. The synthesized breathy samples generated a greater perceptual confusion. The samples with severe deviation seemed to be more susceptible for errors. The synthesized female deviations were correctly classified. The male breathiness and strain were identified as roughness. VoiceSim produced stimuli very similar to the voices of patients with dysphonia. V-SLPs had a better ability to classify human and synthesized voices. VoiceSim is better to simulate vocal breathiness and female deviations; the male samples need adjustment. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    To verify the discriminatory ability of human and synthesized voice samples. This is a prospective study. A total of 70 subjects, 20 voice specialist speech-language pathologists (V-SLPs), 20 general SLPs (G-SLPs), and 30 naive listeners (NLs) participated of a listening task that was simply to classify the stimuli as human or synthesized. Samples of 36 voices, 18 human and 18 synthesized vowels, male and female (9 each), with different type and degree of deviation, were presented with 50% of repetition to verify intrarater consistency. Human voices were collected from a vocal clinic database. Voice disorders were simulated by perturbations of vocal frequency, jitter (roughness), additive noise (breathiness) and by increasing tension and decreasing separation of the vocal folds (strain). The average amount of error considering all groups was 37.8%, 31.9% for V-SLP, 39.3% for G-SLP, and 40.8% for NL. V-SLP had smaller mean percentage error for synthesized (24.7%), breathy (36.7%), synthesized breathy (30.8%), and tense (25%) and female (27.5%) voices. G-SLP and NL presented equal mean percentage error for all voices classification. All groups together presented no difference on the mean percentage error between human and synthesized voices (P value = 0.452). The quality of synthesized samples was very high. V-SLP presented a lower amount of error, which allows us to infer that auditory training assists on vocal analysis tasks. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc.

    Full Text Available As patients become increasingly involved in their medical care, physician-patient communication gains importance. A previous study showed that physician self-disclosure (SD of personal information by primary care providers decreased patient rating of the provider communication skills. The objective of this study was to explore the incidence and impact of emergency department (ED provider self-disclosure on patients’ rating of provider communication skills. A survey was administered to 520 adult patients or parents of pediatric patients in a large tertiary care ED during the summer of 2014. The instrument asked patients whether the provider self-disclosed and subsequently asked patients to rate providers’ communication skills. We compared patients’ ratings of communication measurements between encounters where self-disclosure occurred to those where it did not. Patients reported provider SD in 18.9% of interactions. Provider SD was associated with more positive patient perception of provider communication skills (p<0.05, more positive ratings of provider rapport (p<0.05 and higher satisfaction with provider communication (p<0.05. Patients who noted SD scored their providers’ communication skills as “excellent” (63.4% compared to patients without selfdisclosure (47.1%. Patients reported that they would like to hear about their providers’ experiences with a similar chief complaint (64.4% of patients, their providers’ education (49%, family (33%, personal life (21% or an injury/ailment unlike their own (18%. Patients responded that providers self-disclose to make patients comfortable/at ease and to build rapport. Provider self-disclosure in the ED is common and is associated with higher ratings of provider communication, rapport, and patient satisfaction. [West J Emerg Med. 2017;18(143-49.

    Porcelain has been one of dental biomaterials which can be used to restore tooth structure. Veneer and jacket crown were the examples of dental porcelain restoration. Since wear resistance is related to the strength on its surface, then Vickers Hardness Test of the synthesized porcelain was applied subsequently. If the porcelain hardness number is too high, it should be considered that an abrasion of the opposing teeth could occur. On previous research, dental porcelain had been successfully synthesized from Indonesian natural sand. In this experiment, 5 samples were prepared from a mixture of 65w/o Pangaribuan feldspar, 25w/o Belitung silica, 5w/o Sukabumi kaolinite, and 5w/o potassium salt. This synthesized porcelain samples were invested on 5 cm diameter resin each. A kilogram of load was placed on top of each sample for 10 seconds on 7 different indented areas using ZwickRoell Indentec ZHVμ Micro Vickers. The average hardness number of synthesized dental porcelain made from Indonesian natural sand was 936.06 VHN which was higher than the average hardness number of porcelain restoration. In conclusion of the hardness test, synthesized dental porcelain made from Indonesian natural sand can potentially be used as a core, which shall support hardness and strength of the crown restoration.

    A low-power frequency synthesizer for GPS/Galileo L1/E1 band receivers implemented in a 0.18 μm CMOS process is introduced. By adding clock-controlled transistors at latch outputs to reduce the time constant at sensing time, the working frequency of the high-speed source-coupled logic prescaler supplying quadrature local oscillator signals has been increased, compared with traditional prescalers. Measurement results show that this synthesizer achieves an in-band phase noise of -87 dBc/Hz at 15 kHz offset, with spurs less than -65 dBc. The whole synthesizer consumes 6 mA in the case of a 1.8 V supply, and its core area is 0.6 mm 2 . (semiconductor integrated circuits)

PAN was irradiated by 60 Co γ-radiation with the dose rate 0.9 mrad/H at 77 and 300 K. All PAN samples, irradiated at 77 K, provided similar ESR spectra. Free radicals, formed in PAN, γ-irradiated at 300 K and synthesized at high pressures (to 500 MPa), differ considerably as to the storing concentration, and stability from free radicals in PAN, synthesized at atmospheric pressure. The higher the PAN synthesis temperature is, the lower is their threshold concentration

    Nerve endings of squid photoreceptor neurons generate large synaptosomes upon homogenization of the optic lobe. Using several independent methods, these presynaptic structures have been shown to synthesize a wealth of soluble, cytoskeletal and nuclear encoded mitochondrial proteins, and to account for essentially all the translation activity of the synaptosomal fraction. We are now presenting evidence that calexcitin, a learning related, Ca(2+)-binding protein of the B photoreceptors of Hermissenda crassicornis (a mollusk), is synthesized and subjected to post-translational modifications in the squid photoreceptor terminals. In view of the essential role of presynaptic protein synthesis in long-term memory formation in Aplysia, our data suggest that a comparable role may be played by calexcitin synthesized in the squid photoreceptor terminals.

    This paper reports an attempt to synthesize non toxic zinc oxide (ZnO) nano crystals using a simple quenching technique. The hot zinc oxide powder was quenched in hexane solution to obtain ZnO nano crystals. As the result, diameter size of the synthesized ZnO is 200 nm. It was also exhibited a good crystalline with wurtzite phase. The nano crystals properties of ZnO were revealed from good absorbance and green luminescence under UV exposure. This may be related with oxygen vacancy ionization during the annealing process. (author)

    We investigate the tuning behavior of a novel type of single-frequency optical synthesizers by phase comparison of the output signals of two identical devices. We achieve phase-stable and cycle-slip free frequency tuning over 28.1 GHz with a maximum zero-to-peak phase deviation of 62 mrad. In contrast to previous implementations of single-frequency optical synthesizers, no comb line order switching is needed when tuned over more than one comb line spacing range of the employed frequency comb.

    Worldwide, multicultural interaction within health care seems to be challenging and problematic. This is also true among Primary Child Health Care nurses (PCHC nurses) in the Swedish Primary Child Health Care services (PCHC services). Therefore, there was a need to investigate the parents' perspective in-depth. The aim of the study was to construct a theoretical model that could promote further understanding of the variety of experiences of parents of foreign origin regarding their interaction with the PCHC nurses at PCHC services. The study used Grounded Theory Methodology. Twenty-one parents of foreign origin in contact with PCHC servicies were interviewed. In our study parents were watchfully checking rapport, i.e. if they could perceive sympathy and understanding from the PCHC nurses. This was done by checking the nurse's demeanour and signs of judgement. From these interviews we created a theoretical model illustrating the interactive process between parents and PCHC nurses. We found it to be of utmost importance for parents to be certain that it was possible to establish rapport with the PCHC nurse. If not, disruptions in the child's attendance at PCHC services could result. PCHC nurses can use the theoretical model resulting from this study as a basis for understanding parents, avoiding a demeanour and judgements that may cause misunderstandings thus promoting high-quality interaction in PCHC services.

    Preventing health care-associated infections is essential to the safety and quality of health care. Although patients' experience of care under isolation is well established, little is known of health care workers' experiences when providing such care. This study explored the health professionals; lived experience of caring for patients under transmission-based precautions. Interpretive phenomenology was used to examine 12 health care professionals' lived experience of providing care under transmission-based precautions in 3 health care facilities in Australia. Data were obtained from in-depth interviews and observations of health professionals. The essential phenomena of "recognizing rapport" represented the health professionals' lived experience. Three themes emerged starting with (1) relationships with others, their rapport and communication with patients, patients' families and visitors, and colleagues. These relationships are influenced by (2) barriers to practice, such as personal level of comfort when wearing personal protective equipment, physical limitations of the environment, and management of workload and resources. Such barriers influence (3) patient outcomes, namely the quality of the care provided and adverse events. In the context of caring for patients under transmission-based precautions, the relationships between health professionals and their patients are critical to the quality and safety of health care with respect to infection prevention and control.

    Silver nanoparticles (Ag NPs) were synthesized by a simple microwave irradiation method using polyvinyl pyrrolidone (PVP) as a capping agent and serine as a reducing agent. UV–Visible spectra were used to confirm the formation of Ag NPs by observing the surface plasmon resonance (SPR) band at 443 nm. The emission spectrum of Ag NPs showed an emission band at 484 nm. In the presence of microwave radiation, serine acts as a reducing agent, which was confirmed by Fourier transformed infrared (FT-IR) spectrum. High-resolution transmission electron microscopy (HR-TEM) and high-resolution scanning electron microscopy (HR-SEM) were used to investigate the morphology of the synthesized sample. These images showed the sphere-like morphology. The elemental composition of the sample was determined by the energy dispersive X-ray analysis (EDX). Selected area electron diffraction (SAED) was used to find the crystalline nature of the Ag NPs. The electrochemical behavior of the synthesized Ag NPs was analyzed by the cyclic voltammetry (CV). Antibacterial experiments showed that the prepared Ag NPs showed relatively similar antibacterial activities, when compared with AgNO{sub 3} against Gram-positive and Gram-negative bacteria. - Highlights: • Microwave irradiation method is used to synthesize silver nanoparticles. • Highly stable silver nanoparticles are produced from serine. • A detailed study of antibacterial activities is discussed. • Formation mechanism of silver microspheres has been proposed.

    2014-05-28

    Rhythmic clock widely occurs in biological systems which controls several aspects of cell physiology. For the different cell types, it is supplied with various rhythmic frequencies. How to synthesize a specific clock signal is a preliminary but a necessary step to further development of a biological computer in the future. This paper presents a genetic sequential logic circuit with a clock pulse generator based on a synthesized genetic oscillator, which generates a consecutive clock signal whose frequency is an inverse integer multiple to that of the genetic oscillator. An analogous electronic waveform-shaping circuit is constructed by a series of genetic buffers to shape logic high/low levels of an oscillation input in a basic sinusoidal cycle and generate a pulse-width-modulated (PWM) output with various duty cycles. By controlling the threshold level of the genetic buffer, a genetic clock pulse signal with its frequency consistent to the genetic oscillator is synthesized. A synchronous genetic counter circuit based on the topology of the digital sequential logic circuit is triggered by the clock pulse to synthesize the clock signal with an inverse multiple frequency to the genetic oscillator. The function acts like a frequency divider in electronic circuits which plays a key role in the sequential logic circuit with specific operational frequency. A cascaded genetic logic circuit generating clock pulse signals is proposed. Based on analogous implement of digital sequential logic circuits, genetic sequential logic circuits can be constructed by the proposed approach to generate various clock signals from an oscillation signal.

    In low and medium energy synchrotrons the beam revolution frequency changes by a large factor during the acceleration process. High production rates require that these machines cycle rapidly. In attempting to diagnose instabilities which develop during the acceleration process it is useful to be able to select some frequency segment between revolution harmonics for viewing. Most types of test equipment operating in the frequency domain, such as spectrum analyzers and network analyzers, are not suited to making direct measurements on such rapidly sweeping signals. Ideally, one would want to set the frequency frame of reference to the spot in the accelerating revolution harmonic domain where the measurements are to be made. A scheme using a direct digital synthesizer (DDS) was developed to provide this moving reference frame. This paper describes a synthesizer scheme combining digital and analog synthesizer techniques to allow tracking of signals during acceleration. Virtually any ratio of synthesizer to beam revolution frequency may be generated by this scheme. Details of hardware and measurement results are presented

    Synthesis of Nobel metal nanoparticles, play a key role in the field of medicine. Plants contain a substantial number of organic constituents, like phenolic compounds and various types of glycosides that help in synthesis of metal nanoparticles. Synthesis of metal nanoparticles by green method is one of the best and environment friendly methods. The major significance of the green synthesis is lack of toxic by-products produced during metal nanoparticle synthesis. The nanoparticles, synthesized by green method show various significant biological activities. Most of the research articles report the synthesized nanoparticles to be active against gram positive and gram negative bacteria. Some of these bacteria include Escherichia coli, Bacillus subtilis, Klebsiella pneumonia and Pseudomonas fluorescens. The synthesized nanoparticles also show significant antifungal activity against Trichophyton simii, Trichophyton mentagrophytes and Trichophyton rubrum as well as different types of cancer cells such as breast cancer cell line. They also exhibit significant antioxidant activity. The activities of these Nobel metal nano-particles mainly depend on the size and shape. The particles of small size with large surface area show good activity in the field of medicine. The synthesized nanoparticles are also active against leishmanial diseases. This research article explores in detail the green synthesis of the nanoparticles and their uses thereof. Copyright © 2017 Elsevier B.V. All rights reserved.

Les procédés de transformation du charbon en liquides et gaz sont nombreux, parmi lesquels l'hydroliquéfaction. Cette revue est un examen bibliographique des études fondamentales relatives à l'hydroliquéfaction. Les mécanismes généraux de l'hydroliquéfaction sont passés en revue: dissolution physique du charbon, formation de radicaux libres par rupture thermique des liaisons faibles, conversion de composés modèles possédant les groupements fonctionnels présents dans le charbon et pouvant servir de point de départ pour la rupture, stabilisation de ces radicaux par l'hydrogène provenant soit des composés hydroaromatiques de l'huile de recyclage, soit du charbon lui-même. Les méthodes de séparation et de caractérisation des produits de liquéfaction sont décrites, ainsi que les nombreux modèles cinétiques proposés. La nature des matières minérales et leur rôle catalytique sont décrits. Les catalyseurs ajoutés (hétérogènes, sels fondus ou homogènes sont cités et leurs effets sont étudiés, en particulier l'action favorable des sulfures de fer et des catalyseurs à l'étain.

    Full Text Available Parmi les sources d'énergie et de matières premières capables de se substituer au pétrole et au gaz naturel, le charbon figure en bonne place. Les procédés de transformation du charbon en liquides et gaz sont nombreux, parmi lesquels l'hydroliquéfaction. Cette revue est un examen bibliographique des études fondamentales relatives à l'hydroliquéfaction. Les mécanismes généraux de l'hydroliquéfaction sont passés en revue: dissolution physique du charbon, formation de radicaux libres par rupture thermique des liaisons faibles, conversion de composés modèles possédant les groupements fonctionnels présents dans le charbon et pouvant servir de point de départ pour la rupture, stabilisation de ces radicaux par l'hydrogène provenant soit des composés hydroaromatiques de l'huile de recyclage, soit du charbon lui-même. Les méthodes de séparation et de caractérisation des produits de liquéfaction sont décrites, ainsi que les nombreux modèles cinétiques proposés. La nature des matières minérales et leur rôle catalytique sont décrits. Les catalyseurs ajoutés (hétérogènes, sels fondus ou homogènes sont cités et leurs effets sont étudiés, en particulier l'action favorable des sulfures de fer et des catalyseurs à l'étain. L'effet promoteur de H2S pour la liquéfaction et les causes possibles de désactivation des catalyseurs sont cités. Among sources of energy and raw materials capable of being used in place of oil and natural gas, coal is in a good position. There are many processes for transforming coal into liquids and gas. One of them is hydroliquefaction. This article is a bibliographic review of fundamental research concerning hydroliquefaction. The general mechanisms of hydroliquefaction are reviewed, i. e. the physical dissolution of coal, the formation of free radicals by the thermal breaking of weak bonds, the conversion of model compounds containing the same functional groups as the ones present in coal

  8. Methods of synthesizing qualitative research studies for health technology assessment.

    Synthesizing qualitative research is an important means of ensuring the needs, preferences, and experiences of patients are taken into account by service providers and policy makers, but the range of methods available can appear confusing. This study presents the methods for synthesizing qualitative research most used in health research to-date and, specifically those with a potential role in health technology assessment. To identify reviews conducted using the eight main methods for synthesizing qualitative studies, nine electronic databases were searched using key terms including meta-ethnography and synthesis. A summary table groups the identified reviews by their use of the eight methods, highlighting the methods used most generally and specifically in relation to health technology assessment topics. Although there is debate about how best to identify and quality appraise qualitative research for synthesis, 107 reviews were identified using one of the eight main methods. Four methods (meta-ethnography, meta-study, meta-summary, and thematic synthesis) have been most widely used and have a role within health technology assessment. Meta-ethnography is the leading method for synthesizing qualitative health research. Thematic synthesis is also useful for integrating qualitative and quantitative findings. Four other methods (critical interpretive synthesis, grounded theory synthesis, meta-interpretation, and cross-case analysis) have been under-used in health research and their potential in health technology assessments is currently under-developed. Synthesizing individual qualitative studies has becoming increasingly common in recent years. Although this is still an emerging research discipline such an approach is one means of promoting the patient-centeredness of health technology assessments.

    A new class of nanomaterials, namely microbiologically-formed nanorods composed of elemental tellurium [Te(0)] that forms unusual nanocomposites when combined with poly(m-phenylenevinylene-co-2,5-dioctoxy-phenylenevinylene) (PmPV) is described. These bio-nanocomposites exhibit excellent broadband optical limiting at 532 and 1064 nm. Nonlinear scattering, originating from the laser induced solvent bubbles and microplasmas, is responsible for this nonlinear behavior. The use of bacterially-formed Te(0) when combined with an organic chemical host (e.g., PmPV) is a new green method of nanoparticle syntheses. This opens the possibilities of using unique, biologically synthesized materials to advance future nanoelectronic and nanophotonic applications. ?? 2009 Elsevier B.V. All rights reserved.

    Full Text Available In this information age, different kinds of photosensitive materials have been used in the manufacture of information storage devices. But these photosensitive materials have the bane of low diffraction efficiency. In order to solve this problem, we have synthesized a novel photosensitive polymer from epoxy-based azopolymers (with three types of azochromophores. Furthermore, we have studied the interaction between this newly synthesized azopolymer and ionic liquids (ILs. For this purpose, we have used the ammonium and imidazolium families of ILs, such as diethylammonium dihydrogen phosphate (DEAP, tributylammonium methyl sulfate (TBMS, triethylammonium 4-aminotoluene-3-sulfonic acid (TASA, and 1-methylimidazolium chloride ([Mim]Cl. To investigate the molecular interaction between azopolymer and ILs, we have used the following spectroscopic methods of analysis: UV-visible spectroscopy, photoluminescence (PL spectroscopy, Fourier transformed infrared spectroscopy (FT-IR, and confocal Raman spectroscopy. In this study, we have developed new photosensitive materials by combining polymer with ILs.

  15. Is Ghrelin Synthesized in the Central Nervous System?

    2017-03-01

    Full Text Available Ghrelin is an octanoylated peptide that acts via its specific receptor, the growth hormone secretagogue receptor type 1a (GHSR-1a, and regulates a vast variety of physiological functions. It is well established that ghrelin is predominantly synthesized by a distinct population of endocrine cells located within the gastric oxyntic mucosa. In addition, some studies have reported that ghrelin could also be synthesized in some brain regions, such as the hypothalamus. However, evidences of neuronal production of ghrelin have been inconsistent and, as a consequence, it is still as a matter of debate if ghrelin can be centrally produced. Here, we provide a comprehensive review and discussion of the data supporting, or not, the notion that the mammalian central nervous system can synthetize ghrelin. We conclude that no irrefutable and reproducible evidence exists supporting the notion that ghrelin is synthetized, at physiologically relevant levels, in the central nervous system of adult mammals.

    Polymethylmethacrylate (PMMA) and polyimide (PI) samples are implanted by 40 keV Cu+ ions with high fluences in order to synthesize copper nanoparticles in shallow polymer layers. The produced metal/polymer nanocomposites are studied using atomic force and scanning electron microscopies as well...... as optical transmission spectroscopy. It is found that copper nanoparticles nucleation and growth are strongly fluence dependent as well as they are affected by the polymer properties, in particular, by radiation stability yielding different nanostructures for the implanted PI and PMMA. Shallow synthesized...... nanoparticles are observed to partly tower above the sample surface due to a side effect of high-fluence irradiation leading to considerable sputtering of polymers. Implantation and particle formation significantly change optical properties of both polymers reducing transmittance in the UV-visible range due...

    Full Text Available Bismuth ferrite, BiFeO3 (BFO, powder was synthesized by hydrothermal method from Bi(NO33·5 H2O and Fe(NO33·9 H2O as precursors. The synthesized powder was further sintered using spark plasma sintering (SPS. The sintering conditions were optimized in order to achieve high density, minimal amount of secondary phases and improved ferroelectric and magnetic properties. The optimal structure and properties were achieved after spark plasma sintering at 630 °C for 20 min, under uniaxial pressure of 90 MPa. The composition, microstructure, ferroelectric and magnetic properties of the SPS samples were characterized and compared to those of conventionally sintered ceramics obtained from the same powder. Although the samples sintered using conventional method showed slightly lower amount of secondary phases, the spark plasma sintered samples exhibited favourable microstructure and better ferroelectric properties.

  18. Applications of Magnetosomes Synthesized by Magnetotactic Bacteria in Medicine

    International Nuclear Information System (INIS)

    2014-01-01

    Magnetotactic bacteria belong to a group of bacteria that synthesize iron oxide nanoparticles covered by biological material that are called magnetosomes. These bacteria use the magnetosomes as a compass to navigate in the direction of the earth’s magnetic field. This compass helps the bacteria to find the optimum conditions for their growth and survival. Here, we review several medical applications of magnetosomes, such as those in magnetic resonance imaging (MRI), magnetic hyperthermia, and drug delivery. Different methods that can be used to prepare the magnetosomes for these applications are described. The toxicity and biodistribution results that have been published are summarized. They show that the magnetosomes can safely be used provided that they are prepared in specific conditions. The advantageous properties of the magnetosomes compared with those of chemically synthesized nanoparticles of similar composition are also highlighted.

    A method for synthesizing silica nanofibers using sound waves is provided. The method includes providing a solution of polyvinyl pyrrolidone, adding sodium citrate and ammonium hydroxide to form a first mixture, adding a silica-based compound to the solution to form a second mixture, and sonicating the second mixture to synthesize a plurality of silica nanofibers having an average cross-sectional diameter of less than 70 nm and having a length on the order of at least several hundred microns. The method can be performed without heating or electrospinning, and instead includes less energy intensive strategies that can be scaled up to an industrial scale. The resulting nanofibers can achieve a decreased mean diameter over conventional fibers. The decreased diameter generally increases the tensile strength of the silica nanofibers, as defects and contaminations decrease with the decreasing diameter.

  17. A Novel Synthesizing Genetic Logic Circuit: Frequency Multiplier.

    Science.gov (United States)

    Chuang, Chia-Hua; Lin, Chun-Liang

    2014-01-01

    This paper presents a novel synthesizing genetic logic circuit design based on an existing synthetic genetic oscillator, which provides a function of frequency multiplier to synthesize a clock signal whose frequency is a multiple of that of the genetic oscillator. In the renowned literature, the synthetic genetic oscillator, known as a repressilator, has been successfully built in Escherichia coli to generate a periodic oscillating phenomenon through three repressive genes repress each other in a chain. On the basis of this fact, our proposed genetic frequency multiplier circuit utilizes genetic Buffers in series with a waveform-shaping circuit to reshape the genetic oscillation signal into a crisp logic clock signal. By regulating different threshold levels in the Buffer, the time length of logic high/low levels in a fundamental sinusoidal wave can be engineered to pulse-width-modulated (PWM) signals with various duty cycles. Integrating some of genetic logic XOR gates and PWM signals from the output of the Buffers, a genetic frequency multiplier circuit can be created and the clock signal with the integer-fold of frequency of the genetic oscillator is generated. The synthesized signal can be used in triggering the downstream digital genetic logic circuits. Simulation results show the applicability of the proposed idea.

    Science.gov (United States)

    Thomas, Aliki; Lubarsky, Stuart; Durning, Steven J; Young, Meredith E

    2017-02-01

    An unprecedented rise in health professions education (HPE) research has led to increasing attention and interest in knowledge syntheses. There are many different types of knowledge syntheses in common use, including systematic reviews, meta-ethnography, rapid reviews, narrative reviews, and realist reviews. In this Perspective, the authors examine the nature, purpose, value, and appropriate use of one particular method: scoping reviews. Scoping reviews are iterative and flexible and can serve multiple main purposes: to examine the extent, range, and nature of research activity in a given field; to determine the value and appropriateness of undertaking a full systematic review; to summarize and disseminate research findings; and to identify research gaps in the existing literature. Despite the advantages of this methodology, there are concerns that it is a less rigorous and defensible means to synthesize HPE literature. Drawing from published research and from their collective experience with this methodology, the authors present a brief description of scoping reviews, explore the advantages and disadvantages of scoping reviews in the context of HPE, and offer lessons learned and suggestions for colleagues who are considering conducting scoping reviews. Examples of published scoping reviews are provided to illustrate the steps involved in the methodology.

  19. Radiolytic Syntheses of Nanoparticles and Inorganic-Polymer Hybrid Microgels

    International Nuclear Information System (INIS)

    Chen, Q.; Shi, J.; Zhao, R.; Shen, X.

    2010-01-01

    In the second year of the project, we have gotten progress mainly in two directions. Firstly, for the first time, Prussian blue (PB) nanoparticles (NPs) were successfully synthesized by the partly radiolytic reduction of Fe3+ and Fe(CN)63 in the presence of poly(N-vinyl pyrrolidine) (PVP) under N2 atmospheres at room temperature. With the increase of the concentration of PVP, the size and the size distribution of the synthesized quasi-spherical PB NPs decreased obviously, leading to a hypsochromic shift on their peak position of the characteristic absorption. In the experiment, we further found that the smaller ones have a larger capacity to Cs+, suggesting that the application of PB NPs in curing thallotoxicosis may decrease the usage of PB for the patient to great extent. Secondly, through a series of preliminary experiments, we got a clear picture about the one-step radiolytic preparation of inorganic-poly(methacrylic acid-co-methyl methacrylate) hybrid microgels by surfactant-free emulsion polymerization. Besides, unpurified N-carbamothioylmethacrylamide was synthesized via the methacrylation of thiourea. These created favorable conditions for the one-step synthesis of metal sulfide-poly(methacrylic acid-co-methyl methacrylate) hybrid microgels by -irradiation and surfactant-free emulsion polymerization.

  20. Soft-Template-Synthesized Mesoporous Carbon for Oral Drug Delivery

    Energy Technology Data Exchange (ETDEWEB)

    Saha, Dipendu [ORNL; Warren, Kaitlyn E [ORNL; Naskar, Amit K [ORNL

    2014-01-01

    Template-synthesized mesoporous carbons were successfully used in in vitro investigations of controlled delivery of three model drugs, captopril, furosemide, and ranitidine hydrochloride. Captopril and furosemide exhibited desorption kinetics over 30 40 h, and ranitidine HCl had a complete release time of 5 10 h. As evident from the slow release kinetics, we contend that our mesoporous carbon is an improved drug-delivery medium compared to state-of-the-art porous silica-based substrates. The mesoporous carbons, synthesized from phloroglucinol and lignin, a synthetic and a sustainable precursor, respectively, exhibit BET surface area of 200 400 m2 g-1 and pore volume of 0.2 0.6 cm3 g-1. The phloroglucinol-based carbon has narrower pore widths and higher pore volume than the lignin-derived counterpart and maintains a longer release time. Numerical modeling of the release kinetics data reveals that the diffusivities of all the drugs from lignin-based carbon media are of equivalent magnitude (10-22 to 10-24 m2 s-1). However, a tailored reduction of pore width in the sorbent reduces the diffusivity of smaller drug molecules (captopril) by an order of magnitude. Thus, engineered pore morphology in our synthesized carbon sorbent, along with its potential to tailor the chemistry of its interaction with sorbet, can be exploited for optimal delivery system of a preferred drug within its therapeutic level and below the level of toxicity.

    Highlights: • We bring out a new method to synthesize noble metal phosphides at low temperature. • Both RuP and Ru 2 P were synthesized using triphenylphosphine as phosphorus sources. • Ru 2 P was the better active phase for HDS than RuP and metal Ru. • RuP/SiO 2 prepared by new method had better HDS activity to that by TPR method. - Abstract: Supported noble metal ruthenium phosphides were synthesized by one-step H 2 -thermal treatment method using triphenylphosphine (TPP) as phosphorus sources at low temperatures. Two phosphides RuP and Ru 2 P can be prepared by this method via varying the molar ratio of metal salt and TPP. The as-prepared phosphides were characterized by X-ray powder diffraction (XRD), low-temperature N 2 adsorption, CO chemisorption and transmission electronic microscopy (TEM). The supported ruthenium phosphides prepared by new method and conventional method together with contradistinctive metallic ruthenium were evaluated in hydrodesulfurization (HDS) of dibenzothiophene (DBT). The catalytic results showed that metal-rich Ru 2 P was the better active phase for HDS than RuP and metal Ru. Besides this, ruthenium phosphide catalyst prepared by new method exhibited superior HDS activity to that prepared by conventional method.

    A novel optical security technique for safeguarding user passwords based on an optical fractal synthesizer is proposed. A validating experiment has been carried out. In the proposed technique, a user password is protected by being converted to a fractal image. When a user sets up a new password, the password is transformed into a fractal pattern, and the fractal pattern is stored in authority. If the user is online-validated, his or her password is converted to a fractal pattern again to compare with the previous stored fractal pattern. The converting process is called the fractal encoding procedure, which consists of two steps. First, the password is nonlinearly transformed to get the parameters for the optical fractal synthesizer. Then the optical fractal synthesizer is operated to generate the output fractal image. The experimental result proves the validity of our method. The proposed technique bridges the gap between digital security systems and optical security systems and has many advantages, such as high security level, convenience, flexibility, hyper extensibility, etc. This provides an interesting optical security technique for the protection of digital passwords.

    Full Text Available Polyaniline-montmorillonite (PANI-MMT nanocomposite was synthesized by chemical polymerization of aniline in the presence of montmorillonite (MMT nanostructures. The triple hybrid of polyaniline-polyvinylchloridemontmorillonite (PANI-PVC-MMT was prepared by mixing of the synthesized PANIMMT nanocomposite with a solution of polyvinylchloride (PVC in tetrahydrofurane (THF. In addition, PANI-PVC composite was prepared by mixing of pure synthesized PANI and PVC solution in THF. To investigate the mechanical properties, the PANIPVC composite and PANI- PVC-MMT nanocomposite films were prepared with 5, 10 and 15 wt% of pure PANI and PANI-MMT  nanocomposite, respectively. The results showed that the PANI- PVC-MMT nanocomposite film having 10 wt% of PANIMMT nanocomposite displayed the best mechanical properties. Therefore, it was chosen as optimum film and its physico-chemical properties were characterized. The cyclic voltammetry (CV technique confirmed that the triple hybrid of PANI-PVCMMT nanocomposite was electroactive. Also, Fourier transform infrared (FTIR spectroscopy and scanning electron microscopy (SEM techniques were used to characterize the composition and structure of the PANI-PVC-MMT triple hybrid nanocomposite. X- Ray diffraction (XRD technique showed an intercalated structure for the PANI-PVC-MMT nanocomposite. The thermal stability improvement of the PANI-PVC-MMT nanocomposite in comparison with the pure PVC was established by thermogravimetric analysis (TGA.

    Metal nanoparticle synthesis is an interesting area in nanotechnology due to their remarkable optical, magnetic, electrical, catalytic and biomedical properties, but there needs to develop clean, non-toxic and environmental friendly methods for the synthesis and assembly of nanoparticles. Biological agents in the form of microbes have emerged up as efficient candidates for nanoparticle synthesis due to their extreme versatility to synthesize diverse nanoparticles with varying size and shape. In the present study, an eco favorable method for the biosynthesis of silver nanoparticles using marine bacterial isolate has been attempted. Very interestingly, molecular identification proved it as a strain of Ochrobactrum anhtropi. In addition, the isolate was found to have the potential to form silver nanoparticles intracellularly at room temperature within 24 h. The biosynthesized silver nanoparticles were characterized by UV-Vis spectroscopy, transmission electron microscope (TEM) and scanning electron microscope (SEM). The UV-visible spectrum of the aqueous medium containing silver nanoparticles showed a peak at 450 nm corresponding to the plasmon absorbance of silver nanoparticles. The SEM and TEM micrographs revealed that the synthesized silver nanoparticles were spherical in shape with a size range from 38 nm - 85 nm. The silver nanoparticles synthesized by the isolate were also used to explore its antibacterial potential against pathogens like Salmonella Typhi, Salmonella Paratyphi, Vibrio cholerae and Staphylococcus aureus.

    The high-temperature syntheses of the low-valent halogenides P2I4, Te2Br, α-Te4I4, Te4(Al2Cl7)2, Te4(Bi6Cl20), Te8(Bi4Cl14),Bi8(AlCl4)2, Bi6Cl7,and Bi6Br7, as well as of WSCl4 andWOCl4 have been replaced by resource-efficient low-temperature syntheses in room temperature ionic liquids (RTILs). The simple one-pot syntheses generally do not require elaborate equipment such as twozone furnaces or evacuated silica ampoules. Compared to the published conventional approaches, reduction of reaction time (up to 80%) and temperature (up to 500 K) and, simultaneously, an increase in yield were achieved. In the majority of cases, the solid products were phase-pure. X-Ray diffraction on single crystals (redetermination of 11 crystal structures) has demonstrated that the quality of the crystals from RTILs is comparable to that of products obtained by chemical transport reactions. © 2013 Verlag der Zeitschrift für Naturforschung, Tübingen.

  11. Analyzing and synthesizing phylogenies using tree alignment graphs.

    Directory of Open Access Journals (Sweden)

    Stephen A Smith

    Full Text Available Phylogenetic trees are used to analyze and visualize evolution. However, trees can be imperfect datatypes when summarizing multiple trees. This is especially problematic when accommodating for biological phenomena such as horizontal gene transfer, incomplete lineage sorting, and hybridization, as well as topological conflict between datasets. Additionally, researchers may want to combine information from sets of trees that have partially overlapping taxon sets. To address the problem of analyzing sets of trees with conflicting relationships and partially overlapping taxon sets, we introduce methods for aligning, synthesizing and analyzing rooted phylogenetic trees within a graph, called a tree alignment graph (TAG. The TAG can be queried and analyzed to explore uncertainty and conflict. It can also be synthesized to construct trees, presenting an alternative to supertrees approaches. We demonstrate these methods with two empirical datasets. In order to explore uncertainty, we constructed a TAG of the bootstrap trees from the Angiosperm Tree of Life project. Analysis of the resulting graph demonstrates that areas of the dataset that are unresolved in majority-rule consensus tree analyses can be understood in more detail within the context of a graph structure, using measures incorporating node degree and adjacency support. As an exercise in synthesis (i.e., summarization of a TAG constructed from the alignment trees, we also construct a TAG consisting of the taxonomy and source trees from a recent comprehensive bird study. We synthesized this graph into a tree that can be reconstructed in a repeatable fashion and where the underlying source information can be updated. The methods presented here are tractable for large scale analyses and serve as a basis for an alternative to consensus tree and supertree methods. Furthermore, the exploration of these graphs can expose structures and patterns within the dataset that are otherwise difficult to

    Approximately 60 pure rotational frequency transitions of formaldehyde in its ground state have been measured with sub-MHz uncertainty in the 0.7-1.8 THz frequency range using a photomixing THz synthesizer locked onto a frequency comb. The frequencies associated with previous submillimeter and infrared data have been included in a fit providing a new set of improved molecular parameters. The assignment of each line was checked using the usual statistical diagnostics. Finally, the ability of the continuous-wave spectrometer coupled to a multipass-cell to measure THz rotational transitions of H2CO in the 31, 41 and 61 vibrational states was demonstrated.

    This report presents the results, which were reached in the framework of the BMBF cooperative plan ''Quantum Synthesizer'' in the partial plan ''Integrated Digital Superconducting Logic Circuits''. As essential goal of the plan a novel instrument on the base of quantum-coherent superconducting circuits should be developed. which allows to generate praxis-relevant wave forms with quantum accuracy, the quantum synthesizer. The main topics of development of the reported partial plan lied at the one hand in the development of integrated, digital, superconducting circuit in rapid-single-flux (RSFQ) quantum logics for the pattern generator of the quantum synthesizer, at the other hand in the further development of the fabrication technology for the aiming of high circuit complexity. In order to fulfil these requirements at the PTB a new design system was implemented, based on the software of Cadence. Together with the required RSFQ extensions for the design of digital superconducting circuits was a platform generated, on which the reachable circuit complexity is exclusively limited by the technology parameters of the available fabrication technology: Physical simulations are with PSCAN up to a complexity of more than 1000 circuit elements possible; furthermore VHDL allows the verification of arbitrarily large circuit architectures. In accordance for this the production line at the PTB was brought to a level, which allows in Nb/Al-Al x O y /Nb SIS technology implementation the fabrication of highly integrable RSFQ circuit architectures. The developed and fabricated basic circuits of the pattern generator have proved correct functionality and reliability in the measuring operation. Thereby for the circular RSFQ shift registers a key role as local memories in the construction of the pattern generator is devolved upon. The registers were realized with the aimed bit lengths up to 128 bit and with reachable signal-processing speeds of above 10 GHz. At the interface RSFQ

    The overall objective of the proposed research is to use fundamental advances in bionanotechnology to design powerful platinum nanocrystal electrocatalysts for fuel cell applications. The new economically-viable, environmentally-friendly, bottom-up biochemical synthetic strategy will produce platinum nanocrystals with tailored size, shape and crystal orientation, hence leading to a maximum electrochemical reactivity. There are five specific aims to the proposed bio-inspired strategy for synthesizing efficient electrocatalytic platinum nanocrystals: (1) isolate peptides that both selectively bind particular crystal faces of platinum and promote the nucleation and growth of particular nanocrystal morphologies, (2) pattern nanoscale 2-dimensional arrays of platinum nucleating peptides from DNA scaffolds, (3) investigate the combined use of substrate patterned peptides and soluble peptides on nanocrystal morphology and growth (4) synthesize platinum crystals on planar and large-area carbon electrode supports, and (5) perform detailed characterization of the electrocatalytic behavior as a function of catalyst size, shape and morphology. Project Description and Impact: This bio-inspired collaborative research effort will address key challenges in designing powerful electrocatalysts for fuel cell applications by employing nucleic acid scaffolds in combination with peptides to perform specific, environmentally-friendly, simultaneous bottom-up biochemical synthesis and patterned assembly of highly uniform and efficient platinum nanocrystal catalysts. Bulk synthesis of nanoparticles usually produces a range of sizes, accessible catalytic sites, crystal morphologies, and orientations, all of which lead to inconsistent catalytic activities. In contrast, biological systems routinely demonstrate exquisite control over inorganic syntheses at neutral pH and ambient temperature and pressures. Because the orientation and arrangement of the templating biomolecules can be precisely

    The influence of various parameters on the sinterability of combustion synthesized titanium carbide was investigaged. Titanium carbide powders, prepared by the combustion synthesis process, were sintered in the temperature range 1150 to 1600 0 C. Incomplete combustion and high oxygen contents were found to be the cause of reduced shrinkage during sintering of the combustion syntheized powders when compared to the shrinkage of commercial TiC. Free carbon was shown to inhibit shrinkage. The activation energy for sintering was found to depend on stoichiometry (C/Ti). With decreasing C/Ti, the rate of sintering increased. 29 references, 16 figures, 13 tables

    In this study, we describe a simple method to prepare hybrid nanogels consisting of a biocompatible core-shell polymer host containing silver nanoparticles. First, the nanogels (NG, 160 nm) containing a lysozyme rich core and a dextran rich shell, are prepared via Maillard and heat-gelation reactions. Second, silver nanoparticles (Ag NPs, 5 nm) are synthesized "in situ" in the NG solution without requiring additional reducing agents. This approach leads to stable Ag NPs located in the NG. Furthermore, we demonstrate that the amount of Ag NPs in the NG can be tuned by varying silver precursor concentration. Hybrid nanogels with silver nanoparticles have potential in antimicrobial, optical, and therapeutic applications.

    Full Text Available The paper considers the features of synthesized holograms suitable for practical use. It is established that binary holograms are the first of all suitable ones for successful application in practice. In order to select the most suitable (optimal level of hologram binarization, we propose a criterion for estimating the quality of an image reconstructed with a binary hologram. An algorithm is developed to find the optimal level. On the basis of the conducted experiments it is established that the introduction of the developed module gives the possibility to reduce the search time of the optimal binarization level of the hologram by eleven times in comparison with manual search.

    2010-01-01

    Al 2 O 3 -TiC nanocomposite was synthesized by ball milling of aluminum, titanium oxide and graphite powder mixtures. Effect of the milling time and heat treatment temperatures were investigated. The structural evolution of powder particles after different milling times was studied by X-ray diffractometry and scanning electron microscopy. The results showed that after 40 h of ball milling the Al/TiO 2 /C reacted with a self-propagating combustion mode producing Al 2 O 3 -TiC nanocomposite. In final stage of milling, alumina and titanium carbide crystallite sizes were less than 10 nm. After annealing at 900 o C for 1 h, Al 2 O 3 and TiC crystallite sizes remained constant, however increasing annealing temperature to 1200 o C increased Al 2 O 3 and TiC crystallite size to 65 and 30 nm, respectively. No phase change was observed after annealing of the synthesized Al 2 O 3 -TiC powder.

    An enzymatically-synthesized glycogen (ESG), intended for use as a food ingredient, was investigated for potential toxicity. ESG is synthesized in vitro from short-chain amylose by the co-operative action of branching enzyme and amylomaltase. In an acute toxicity study, oral administration of ESG to Sprague-Dawley rats at a dose of 2000 mg/kg body weight did not result in any signs of toxicity. ESG did not exhibit mutagenic activity in an in vitro bacterial reverse mutation assay. In a subchronic toxicity study, increased cecal weights noted in the mid- (10%) and high-dose (30%) animals are common findings in rodents fed excess amounts of carbohydrates that increase osmotic value of the cecal contents, and thus were considered a physiological rather than toxicological response. The hematological and histopathological effects observed in the high-dose groups were of no toxicological concern as they were secondary to the physiological responses resulting from the high carbohydrate levels in the test diets. The no-observed-adverse-effect level for ESG in rats was therefore established to be 30% in the diet (equivalent to approximately 18 and 21 g/kg body weight/day for male and female rats, respectively). These results support the safety of ESG as a food ingredient for human consumption. Copyright 2010 Elsevier Inc. All rights reserved.

    This study explored the discrimination of synthesized English vowel pairs by 27 American and Korean, male and female listeners. The average formant values of nine monophthongs produced by ten American English male speakers were employed to synthesize the vowels. Then, subjects were instructed explicitly to respond to AX discrimination tasks in which the standard vowel was followed by another one with the increment or decrement of the original formant values. The highest and lowest formant values of the same vowel quality were collected and compared to examine patterns of vowel discrimination. Results showed that the American and Korean groups discriminated the vowel pairs almost identically and their center formant frequency values of the high and low boundary fell almost exactly on those of the standards. In addition, the acceptable range of the same vowel quality was similar among the language and gender groups. The acceptable thresholds of each vowel formed an oval to maintain perceptual contrast from adjacent vowels. Pedagogical implications of those findings are discussed.

    The metasurface lens composing of 2D periodic metallic patches on a grounded dielectric slab possesses several advantages such as being light, low-profile, compact, and also cheap to manufacture. In this paper, a Luneburg lens synthesized by a metasurface and designated for use as a surface wave antenna is proposed. Two types of unit cell will be compared, one whose surface wave modal dispersion varies significantly with the grazing direction and another that does not. In the context of being applied as surface wave antennas, it will be shown that the Luneburg lens synthesized by the latter kind of unit cell provides improved performance as compared to the former. Several aperture sub-efficiencies of the metasurface-based Luneburg-lens antenna shall be used for the characterization of the radiation. A prototype of the designed lens antenna has also been manufactured. Measurement results agree well with theoretical predictions and the efficacy of this device over a fairly wide bandwidth has been experimentally demonstrated.

  11. Protein-synthesizing machinery in the axon compartment.

    Contrary to the prevailing view that the axon lacks the capacity to synthesize proteins, a substantial body of evidence points to the existence of a metabolically active endogenous translational machinery. The machinery appears to be largely localized in the cortical zone of the axon, where, in vertebrate axons, it is distributed longitudinally as intermittent, discrete domains, called periaxoplasmic plaques. Studies, based on translation assays and probes of RNA transcripts in axon models such as the squid giant axon and selected vertebrate axons, provide evidence of locally synthesized proteins, most of which appear to be constituents of the slow axoplasmic transport rate groups. Metabolic and molecular biological findings are consistent with the view that the synthesis of proteins undergoing local turnover in the axonal compartment of macroneurons depends on the activity of an endogenous translational machinery. The documented presence of a metabolically active machinery in presynaptic terminals of squid photoreceptor neurons is also described. Finally, potential sources of axoplasmic RNAs comprising the machinery, which may include the ensheathing cell of the axon, as well as the cognate cell body, are also discussed.

    The way nature evolves and sculpts materials using proteins inspires new approaches to materials engineering but is still not completely understood. Here, we present a cell-free synthetic biological platform to advance studies of biologically synthesized solid-state materials. This platform is capable of simultaneously exerting many of the hierarchical levels of control found in natural biomineralization, including genetic, chemical, spatial, structural, and morphological control, while supporting the evolutionary selection of new mineralizing proteins and the corresponding genetically encoded materials that they produce. DNA-directed protein expression and enzymatic mineralization occur on polystyrene microbeads in water-in-oil emulsions, yielding synthetic surrogates of biomineralizing cells that are then screened by flow sorting, with light-scattering signals used to sort the resulting mineralized composites differentially. We demonstrate the utility of this platform by evolutionarily selecting newly identified silicateins, biomineralizing enzymes previously identified from the silica skeleton of a marine sponge, for enzyme variants capable of synthesizing silicon dioxide (silica) or titanium dioxide (titania) composites. Mineral composites of intermediate strength are preferentially selected to remain intact for identification during cell sorting, and then to collapse postsorting to expose the encoding genes for enzymatic DNA amplification. Some of the newly selected silicatein variants catalyze the formation of crystalline silicates, whereas the parent silicateins lack this ability. The demonstrated bioengineered route to previously undescribed materials introduces in vitro enzyme selection as a viable strategy for mimicking genetic evolution of materials as it occurs in nature.

    We report here the influence of the irradiation with femtosecond laser pulses on the gold nanoprisms synthesized using biological and chemical methods. For the bio-mediated growth, we used plant extract as a source of reducing, structure-directing, and stabilizing agents, while for the chemical method, we applied three-step protocol, involving chemicals commonly used in the synthesis of nanostructures. Exposition of the nanostructures to the laser beam causes morphological changes, which affect their extinction spectra. These modifications were followed using absorption spectroscopy and transmission electron microscopy. The observed effects depend on the applied laser power and excitation wavelength. Under resonance conditions, rounding of the tips of triangular nanoparticles and transformation towards more stable, spherical form were noticed. These changes were faster under higher laser power. Such shape modifications were weaker under off-resonance conditions. Moreover, chemically synthesized gold nanoprisms were less susceptible to the morphological changes than those obtained using plant extract; however, their colloidal stability was disrupted by long-time irradiation.

    Noble metal catalysts have been widely used in many applications because of their high activity and selectivity. However, a controllable preparation of noble metal catalysts still remains as a significant challenge. To overcome this challenge, peptide templates can play a critical role in the controllable syntheses of catalysts owing to their flexible binding with specific metallic surfaces and self-assembly characteristics. By employing peptide templates, the size, shape, facet, structure, and composition of obtained catalysts can all be specifically controlled under the mild synthesis conditions. In addition, catalysts with spherical, nanofiber, and nanofilm structures can all be produced by associating with the self-assembly characteristics of peptide templates. Furthermore, the peptide-templated noble metal catalysts also reveal significantly enhanced catalytic behaviours compared with conventional catalysts because the electron conductivity, metal dispersion, and reactive site exposure can all be improved. In this review, we summarize the research progresses in the syntheses of peptide-templated noble metal catalysts. The applications of the peptide-templated catalysts in organic reactions, photocatalysis, and electrocatalysis are discussed, and the relationship between structure and activity of these catalysts are addressed. Future opportunities, including new catalytic materials designed by using biological principles, are indicated to achieve selective, eco-friendly, and energy neutral synthesis approaches.

  16. Synthesizing Iron Oxide Nanostructures: The Polyethylenenemine (PEI) Role

    Controlled synthesis of anisotropic iron oxide nanoparticles is a challenge in the field of nanomaterial research that requires an extreme attention to detail. In particular, following up a previous work showcasing the synthesis of magnetite nanorods (NRs) using a two-step approach that made use of polyethylenenemine (PEI) as a capping ligand to synthesize intermediate β-FeOOH NRs, we studied the effect and influence of the capping ligand on the formation of β-FeOOH NRs. By comparing the results reported in the literature with those we obtained from syntheses performed (1) in the absence of PEI or (2) by using PEIs with different molecular weight, we showed how the choice of different PEIs determines the aspect ratio and the structural stability of the β-FeOOH NRs and how this affects the final products. For this purpose, a combination of XRD, HRTEM, and direct current superconducting quantum interference device (DC SQUID) magnetometry was used to identify the phases formed in the final products and study their morphostructural features and related magnetic behavior.

    Gold nanoparticles (AuNPs) are a fascinating class of nanomaterial that can be used for a wide range of biomedical applications, including bio-imaging, lateral flow assays, environmental detection and purification, data storage, drug delivery, biomarkers, catalysis, chemical sensors, and DNA detection. Biological synthesis of nanoparticles appears to be simple, cost-effective, non-toxic, and easy to use for controlling size, shape, and stability, which is unlike the chemically synthesized nanoparticles. The aim of this study was to synthesize homogeneous AuNPs using pharmaceutically important Ganoderma spp . We developed a simple, non-toxic, and green method for water-soluble AuNP synthesis by treating gold (III) chloride trihydrate (HAuCl4) with a hot aqueous extract of the Ganoderma spp . mycelia. The formation of biologically synthesized AuNPs (bio-AuNPs) was characterized by ultraviolet (UV)-visible absorption spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray (EDX), dynamic light scattering (DLS), and transmission electron microscopy (TEM). Furthermore, the biocompatibility of as-prepared AuNPs was evaluated using a series of assays, such as cell viability, lactate dehydrogenase leakage, and reactive oxygen species generation (ROS) in human breast cancer cells (MDA-MB-231). The color change of the solution from yellow to reddish pink and strong surface plasmon resonance were observed at 520 nm using UV-visible spectroscopy, and that indicated the formation of AuNPs. DLS analysis revealed the size distribution of AuNPs in liquid solution, and the average size of AuNPs was 20 nm. The size and morphology of AuNPs were investigated using TEM. The biocompatibility effect of as-prepared AuNPs was investigated in MDA-MB-231 breast cancer cells by using various concentrations of AuNPs (10 to 100 μM) for 24 h. Our findings suggest that AuNPs are non-cytotoxic and biocompatible. To the best of our knowledge

    ABSTRACT Meta-analysis is a set of statistical procedures for synthesizing research results from a number of different studies. An estimate of a statistical effect, such as the difference in disease severity for plants with or without a management treatment, is collected from each study along with a measure of the variance of the estimate of the effect. Combining results from different studies will generally result in increased statistical power so that it is easier to detect small effects. Combining results from different studies may also make it possible to compare the size of the effect as a function of other predictor variables such as geographic region or pathogen species. We present a review of the basic methodology for meta-analysis. We also present an example of meta-analysis of the relationship between disease severity and yield loss for foliar wheat diseases, based on data collected from a decade of fungicide and nematicide test results.
