  1. Current and future centrally acting antitussives☆

    PubMed Central

    Bolser, Donald C.

    2011-01-01

    The purpose of this review is to highlight some important issues regarding current centrally acting antitussive drugs as well as discuss the implications of these matters on the development of future cough suppressants. Drugs that act in the central nervous system to inhibit cough are termed centrally acting and this designation is based exclusively on evidence obtained from animal models. This classification can include drugs that act both at peripheral and central sites following systemic administration. These drugs are intended to reduce the frequency and/or intensity of coughing resulting from disorders of any etiology. There are a number of central cough suppressants identified by their efficacy in animal models and the most prominent of these are codeine and dextromethorphan. Although the exact neural elements on which these drugs act are currently unknown, they are thought to inhibit a functionally identified component of the central system for cough known as the gating mechanism. The efficacy of codeine and dextromethorphan in humans has recently been questioned. These drugs are less effective on cough induced by upper airway disorders than in pathological conditions involving the lower airways in humans. The reasons for this difference in antitussive sensitivity are not clear. We propose that sensory afferents from different regions of the airways actuate coughing in humans by antitussive sensitive and insensitive control elements in the central nervous system. This hypothesis is consistent with results from an animal model in which laryngeal and tracheobronchial cough had different sensitivities to codeine. Other factors that may be very important in the action of central antitussive drugs in humans include the role of sensations produced by a tussigenic stimulus as well as plasticity of central pathways in response to airway inflammation. Resolution of these issues in the human will be a challenging process, but one which will lay the foundation for the

    2017-04-01

    We describe the patterns of coverage gains associated with the Affordable Care Act (ACA) expansions and use these patterns to assess the potential impact of alternative repeal or repeal and replace strategies because Congress and the president are weighing options to repeal or replace the ACA. We find that specific provisions of the ACA, including the Medicaid expansion and the structure of premium subsidies, have been associated with large and robust gains in insurance coverage. We evaluate the impact of retaining dependent coverage and high-risk pool provisions and show, on the basis of the ACA experience, that these provisions would have little effect on coverage. We find that many replacement proposal components, including flat tax credits and maintaining cost savings provisions, could jeopardize the ability of many of the ACA's primary beneficiaries, as well as other Americans, to access coverage and care. By leading to a deterioration of the safety net, these strategies could also imperil population health activities.

    2013-01-01

    All organisms capable of long-term memory are necessarily oriented toward the future. We propose that one of the most important adaptive functions of long-term episodic memory is to store information about the past in the service of planning for the personal future. Because a system should have especially efficient performance when engaged in a task that makes maximal use of its evolved machinery, we predicted that future-oriented planning would result in especially good memory relative to other memory tasks. We tested recall performance of a word list, using encoding tasks with different temporal perspectives (e.g., past, future) but a similar context. Consistent with our hypothesis, future-oriented encoding produced superior recall. We discuss these findings in light of their implications for the thesis that memory evolved to enable its possessor to anticipate and respond to future contingencies that cannot be known with certainty.

    Providing care for patients who have carried out criminal acts is a source of questioning for caregivers, who must position themselves in this specific care relationship. For three years, the nursing training institute (IFSI) in Orthez has offered students an optional module in criminology. Through discussions and critical reflection, its aim is to enable future nurses to be better prepared.

    PubMed Central

    2014-01-01

    Much recent research has shown that the capacity for mental time travel and temporal reasoning emerges during the preschool years. Nothing is known so far, however, about young children's grasp of the normative dimension of future-directed thought and speech. The present study is the first to show that children from age 4 understand the normative outreach of such future-directed speech acts: subjects at time 1 witnessed a speaker make future-directed speech acts about/towards an actor A, either in imperative mode (“A, do X!”) or as a prediction (“the actor A will do X”). When at time 2 the actor A performed an action that did not match the content of the speech act at time 1, children identified the speaker as the source of a mistake in the prediction case, and the actor as the source of the mistake in the imperative case and leveled criticism accordingly. These findings add to our knowledge about the emergence and development of temporal cognition in revealing an early sensitivity to the normative aspects of future-orientation. PMID:24489815

    2015-11-01

    In recent years, several direct-acting oral anticoagulants (DOAC) have become available for use in Europe and other regions in indications related to prophylaxis and treatment of venous and arterial thromboembolism. They include the oral direct thrombin inhibitor dabigatran etexilate (Pradaxa, Boehringer Ingelheim) and the oral direct FXa inhibitors rivaroxaban (Xarelto, Bayer HealthCare), apixaban (Eliquis, Bristol-Myers Squibb), and edoxaban (Lixiana/Savaysa, Daiichi-Sankyo). The new compounds have a predictable dose response and few drug-drug interactions (unlike vitamin k antagonists), and they do not require parenteral administration (unlike heparins). However, they accumulate in patients with renal impairment, lack widely available monitoring tests for measuring its anticoagulant activity, and no specific antidotes for neutralization in case of overdose and/or severe bleeding are currently available. In this review, we describe the pharmacology of the DOAC, the efficacy, and safety data from pivotal studies that support their currently approved indications and discuss the postmarketing experience available. We also summarize practical recommendations to ensure an appropriate use of the DOAC according to existing data. Finally, we discuss relevant ongoing studies and future perspectives.

    Despite extensive knowledge of how to prevent or ameliorate serious diseases, natural disasters, environmental degradation, and a wide range of other problems, we often fail to take action that that would prevent or mitigate these problematic outcomes. In short, although we may have sound scientific knowledge about threats to future wellbeing, we appear to have limited insight into how to benefit from this knowledge. With this paper, we argue that our current scientific understanding of how to act in light of the future is limited, but we offer a theoretical analysis of future-oriented behavior at both individual and organizational levels. Specifically, the paper draws on a functional contextualist account of human language and cognition, Relational Frame Theory (RFT), and its integrated therapeutic approach, Acceptance and Commitment Therapy (ACT), and extends this framework to analyzing the evolution of the practices of groups and organizations. This framework can provide an understanding of how human behavior may be modified in the present to serve improving human wellbeing in the future at individual, organizational, and even national levels.

    2010-10-19

    The Affordable Care Act is a once-in-a-generation change to the U.S. health system. It guarantees access to health care for all Americans, creates new incentives to change clinical practice to foster better coordination and quality, gives physicians more information to make them better clinicians and patients more information to make them more value-conscious consumers, and changes the payment system to reward value. The Act and the health information technology provisions in the American Recovery and Reinvestment Act remove many barriers to delivering high-quality care, such as unnecessary administrative complexity, inaccessible clinical data, and insufficient access to primary care and allied health providers. We hope that physicians will embrace the opportunities created by the Affordable Care Act that will enable them to provide better care for their patients and lead the U.S. health system in a more positive direction. To fully realize the benefits of the Affordable Care Act for their practices and their patients, physicians will design their offices for seamless care, employing new practice models and using technology to integrate patient information with professional society guidelines to keep patients with chronic conditions healthy and out of the hospital. Under the Affordable Care Act, physicians who effectively collaborate with other providers to improve patient outcomes, the value of medical services, and patient experiences will thrive and be the leaders of the health care system.

    Hepatitis C virus (HCV) infection has been a global health problem for decades, due to the high number of infected people and to the lack of effective and well-tolerated therapies. In the last 3 years, the approval of new direct acting antivirals characterized by high rates of virological clearance and excellent tolerability has dramatically improved HCV infection curability, especially for patients with advanced liver disease and for liver transplant recipients. Long-term data about the impact of the new direct acting antivirals on liver fibrosis and liver disease-related outcomes are not yet available, due to their recent introduction. However, previously published data deriving from the use of pegylated-interferon and ribavirin lead to hypothesizing that we are going to observe, in the future, a reduction in mortality and in the incidence of hepatocellular carcinoma, as well as a regression of fibrosis for people previously affected by hepatitis C. In the liver transplant setting, clinical improvement has already been described after treatment with the new direct acting antivirals, which has often led to patients delisting. In the future, this may hopefully reduce the gap between liver organ request and availability, probably expanding liver transplant indications to other clinical conditions. Therefore, these new drugs are going to change the natural history of HCV-related liver disease and the epidemiology of HCV infection worldwide. However, the global consequences will depend on treatment accessibility and on the number of countries that could afford the use of the new direct acting antivirals. PMID:28321272

  12. Causation's nuclear future: applying proportional liability to the Price-Anderson Act.

    PubMed

    O'Connell, William D

    2014-11-01

    For more than a quarter century, public discourse has pushed the nuclear-power industry in the direction of heavier regulation and greater scrutiny, effectively halting construction of new reactors. By focusing on contemporary fear of significant accidents, such discourse begs the question of what the nation's court system would actually do should a major nuclear incident cause radiation-induced cancers. Congress's attempt to answer that question is the Price-Anderson Act, a broad statute addressing claims by the victims of a major nuclear accident. Lower courts interpreting the Act have repeatedly encountered a major stumbling block: it declares that judges must apply the antediluvian preponderance-of-the-evidence logic of state tort law, even though radiation science insists that the causes of radiation-induced cancers are more complex. After a major nuclear accident, the Act's paradoxically outdated rules for adjudicating "causation" would make post-incident compensation unworkable. This Note urges that nuclear-power-plant liability should not turn on eighteenth-century tort law. Drawing on modern scientific conclusions regarding the invariably "statistical" nature of cancer, this Note suggests a unitary federal standard for the Price-Anderson Act--that a defendant be deemed to have "caused" a plaintiff's injury in direct proportion to the increased risk of harm the defendant has imposed. This "proportional liability" rule would not only fairly evaluate the costs borne by injured plaintiffs and protect a reawakening nuclear industry from the prospect of bank-breaking litigation, but would prove workable with only minor changes to the Price-Anderson Act's standards of "injury" and "fault."

  14. Regulating dangerous futures: the German Embryo Protection Act of 1990--legislation in risk society.

    PubMed

    Augst, C

    2000-06-01

    This article summarises the outcome of a research project which analyses the legislative debate about the German Embryonenschutzgesetz (Embryo Protection Act) in 1990. From 1988 to 1990 the German Parliament discussed legislation for the practice of assisted contraception and embryo research. The term 'risk' is central to the discourse. For Ulrich Beck (1986) this emphasis on risk is a sign of the reflexivity which contemporary western societies have reached. This article reads back into the risk discourse the values hidden in risk terminology: they are identified as fears about modernisation processes. The focus on risk in this article allows observation of late modernity's unease about its own potential and a growing ambiguity about modern ideas of progress and control (Bauman, 1991). This ambiguity also becomes apparent in the strategies of policing which the German legislature offers as solutions to the perceived risks: different legislative strategies are developed to tackle the contradictory risk scenarios. These different strategies of policing are understood as the construction of 'places of safety' in the face of identified dangers: the 'traditional family', the 'good doctor', 'professional' judgement. Defining those boundaries allows the German legislature to juggle contradictory agendas. This explains the inconsistent and fragmented nature of the Embryo Protection Act 1990.

  15. Long-Acting Muscarinic Antagonists for Difficult-to-Treat Asthma: Emerging Evidence and Future Directions.

    Bulkhi, Adeeb; Tabatabaian, Farnaz; Casale, Thomas B

    2016-07-01

    Asthma is a complex disease where many patients remain symptomatic despite guideline-directed therapy. This suggests an unmet need for alternative treatment approaches. Understanding the physiological role of muscarinic receptors and the parasympathetic nervous system in the respiratory tract will provide a foundation of alternative therapeutics in asthma. Currently, several long-acting muscarinic antagonists (LAMAs) are on the market for the treatment of respiratory diseases. Many studies have shown the effectiveness of tiotropium, a LAMA, as add-on therapy in uncontrolled asthma. These studies led to FDA approval for tiotropium use in asthma. In this review, we discuss how the neurotransmitter acetylcholine itself contributes to inflammation, bronchoconstriction, and remodeling in asthma. We further describe the current clinical studies evaluating LAMAs in adult and adolescent patients with asthma, providing a comprehensive review of the current known physiological benefits of LAMAs in respiratory disease.

  16. The future of benefit-cost analyses of the Clean Air Act.

    PubMed

    Krupnick, Alan; Morgenstern, Richard

    2002-01-01

    This review examines the first two studies conducted pursuant to a Congressional mandate that the U.S. Environmental Protection Agency analyze the effects of the Clean Air Act on the "public health, economy, and the environment of the United States." While these studies indicate that overall, the nation received good value for the resources it invested in improving air quality over the past three decades, we don't know if even higher value could have been obtained by changing or eliminating certain potentially inefficient elements. The review focuses on the critical policy and technical choices made in the analyses, including the selection of the appropriate baseline and the level of disaggregation for the studies. It is proposed that a potential third analysis focus on potential new policies not yet mandated by law or regulation. It is also proposed that the next study fill in key information gaps, expand the benefit categories, and incorporate new research on topics such as mortality and morbidity benefits, cost uncertainties, and others.

    2012-01-01

    RÉSUMÉ Même si, au Canada, les mineurs n’ont pas le droit de jouer à des jeux de hasard légalisés, les adolescents participent souvent à des jeux de hasard soit légalisés (produits de loterie, casino, terminaux de jeux vidéo), soit autonomes (jeux de cartes, paris sportifs, dés) à la maison et en milieu scolaire. Chez les adultes, le taux de prévalence de dépendance aux jeux de hasard au cours de la vie se situe entre 1 % et 2 %. D’après les données existantes, la prévalence chez les adolescents serait de deux à quatre fois plus élevée. On ne sait pas grand-chose des facteurs de risque d’apparition et de perpétuation d’une dépendance pathologique aux jeux de hasard. Le présent document de principes vise à informer les pédiatres, les médecins de famille et les autres professionnels de la santé des connaissances émergentes sur les jeux de hasard pendant l’enfance et l’adolescence et du risque de conséquences graves qui s’y rattachent. On y exhorte également les gouvernements fédéral, provinciaux et territoriaux à inclure cette question dans leur programme et à tenir compte des facteurs sociopolitiques associés aux jeux de hasard.

    This study investigated the development of the ability to reflect on one's personal past and future. A total of 64 4- to 6-year-olds received tasks of delayed self-recognition, source memory, delay of gratification, and a newly developed task of future-oriented action timing. Although children's performance on delayed self-recognition, source memory, and action timing improved with age, their performance on delay of gratification did not. Children's errors in source memory and action timing were solely and strongly associated with each other in older children (5-6years) even after controlling for age and verbal ability. Results are discussed in terms of mental time travel underlying episodic memory and future thinking that includes both the projection of oneself into the past and future and the appreciation of events' temporal relations.

    Passed in 1972, the Marine Mammal Protection Act has two fundamental objectives: to maintain U.S. marine mammal stocks at their optimum sustainable populations and to uphold their ecological role in the ocean. The current status of many marine mammal populations is considerably better than in 1972. Take reduction plans have been largely successful in reducing direct fisheries bycatch, although they have not been prepared for all at-risk stocks, and fisheries continue to place marine mammals as risk. Information on population trends is unknown for most (71%) stocks; more stocks with known trends are improving than declining: 19% increasing, 5% stable, and 5% decreasing. Challenges remain, however, and the act has generally been ineffective in treating indirect impacts, such as noise, disease, and prey depletion. Existing conservation measures have not protected large whales from fisheries interactions or ship strikes in the northwestern Atlantic. Despite these limitations, marine mammals within the U.S. Exclusive Economic Zone appear to be faring better than those outside, with fewer species in at-risk categories and more of least concern.

  7. The Changing Dynamics Of US Health Insurance And Implications For The Future Of The Affordable Care Act.

    2017-02-01

    The introduction of Medicaid expansions and state Marketplaces under the Affordable Care Act (ACA) have reduced the uninsurance rate to historic lows, changing the choices Americans make about coverage. In this article we shed light on these changing dynamics. We drew upon multistate transition models fit to nationally representative longitudinal data to estimate coverage transition probabilities between major insurance types in the years leading up to and including 2014. We found that the ACA's unprecedented coverage changes increased transitions to Medicaid and nongroup coverage among the uninsured, while strengthening the existing employer-sponsored insurance system and improving retention of public coverage. However, our results suggest possible weakness of state Marketplaces, since people gaining nongroup coverage were disproportionately older than other potential enrollees. We identified key opportunities for policy makers and insurers to improve underlying Marketplace risk pools by focusing on people transitioning from employer-sponsored coverage; these people are disproportionately younger and saw almost no change in their likelihood of becoming uninsured in 2014 compared to earlier years.

  8. LES versus DNS: A comparative study

    Shtilman, L.; Chasnov, J. R.

    1992-01-01

    We have performed Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES) of forced isotropic turbulence at moderate Reynolds numbers. The subgrid scale model used in the LES is based on an eddy viscosity which adjusts instantaneously the energy spectrum of the LES to that of the DNS. The statistics of the large scales of the DNS (filtered DNS field or fDNS) are compared to that of the LES. We present results for the transfer spectra, the skewness and flatness factors of the velocity components, the PDF's of the angle between the vorticity and the eigenvectors of the rate of strain, and that between the vorticity and the vorticity stretching tensor. The above LES statistics are found to be in good agreement with those measured in the fDNS field. We further observe that in all the numerical measurements, the trend was for the LES field to be more gaussian than the fDNS field. Future research on this point is planned.

    Affections gravissimes à pronostic très réservé particulièrement dans notre contexte de sous médicalisation et de pauvreté. Notre but en initiant ce travail est de déterminer les étiologies de ces urgences et discuter de leur prise en charge thérapeutique. Étude de type rétrospective et descriptive sur 05 ans, au total 52 dossiers cliniques ont été inclus. Ces infections ont représenté 0,33% de nos consultations. La moyenne d'âge de nos patients a été 23 ans. Le jeune âge, les traitements inappropriés et certaines affections ORL ont été retrouvés comme facteurs favorisants. Les motifs de consultation ont été variés en fonction du siège de l'infection, cependant deux signes cliniques ont été constants: la douleur et la fièvre. L'adénophlegmon, le phlegmon péri-amygdalien, les cellulites ont été nos principales étiologies avec le streptocoque et le staphylocoque comme principaux germes en cause. L'antibiothérapie probabiliste a été utilisée en première intention notamment l'association céphalosporine de 3ème génération + aminoside + imidazolé. L'évolution clinique de nos patients a été marquée par la survenue de complications locales et générales. Urgence diagnostic et thérapeutique leur évolution reste encore émaillée de complication en raison de la consultation tardive de nos patients. PMID:28154719

    2015-11-01

    The German Psychiatry Personnel Act, which went into effect in 1990, has led to a decrease in the number of child and adolescent psychiatry inpatient beds, to a decrease in the length of stay, and to an increase in inpatient psychotherapy. Today, this act is outdated~ for a number of reasons, such as changes in the morbidity of the population, the rising number of emergencies, and new professional standards such as documentation. In addition, new legal provisions and conventions (like the UN Convention on the Rights of the Child) necessitate a complete reevaluation. Child and adolescent psychiatry needs a normative act to enable the necessary implementation. Many different rationales are available to support the debate.

    Les galaxies spriales presentent une distribution continue de formes et de proprietes physiques. A l'heure actuelle, il existe deux ecoles de pensee au sujet de la nature de ces proprietes morphologiques des galaxies. Pour certains elles sont innees, pour d'autres elles sont acquises. Les gradients d'abondance nebulaires, de par leur sensibilite aux mouvements a grande echelle du gaz et au taux de formation stellaire, offrent une possibilite de trancher dans ce debat. Toutefois, jusqu'ici, on a surtout observe les gradients d'abondance dans les galaxies de type tardif. Le premier objectif de cette these est d'enrichir l'echantillon de galaxies de type precoce observees. Le second objectif est de demontrer qu'il y a deja eu une barre dans les galaxies de type precoce et, si possible, de chercher des traces d'interactions dans ces galaxies. Dans le cadre de cette these, j'ai observe huit galaxies de type precoce. Mes observations indiquent que ces galaxies presentent des profils d'abondance dont les caracteristiques se rapprochent des galaxies barrees, meme si certaines ne presentent pas de barres. Ce resultat renforce l'hypothese selon laquelle les galaxies changent de type morphologique au cours du temps sous l'effet d'instabilites comme les barres.

    Chemical property estimation is a key component in many industrial, academic, and regulatory activities, including in the risk assessment associated with the approximately 1000 new chemical pre-manufacture notices the United States Environmental Protection Agency (US EPA) receives annually. The US EPA evaluates fate, exposure and toxicity under the 1976 Toxic Substances Control Act (amended by the 2016 Frank R. Lautenberg Chemical Safety for the 21(st) Century Act), which does not require test data with new chemical applications. Though the submission of data is not required, the US EPA has, over the past 40 years, occasionally received chemical-specific data with pre-manufacture notices. The US EPA has been actively using this and publicly available data to develop and refine predictive computerized models, most of which are housed in EPI Suite™, to estimate chemical properties used in the risk assessment of new chemicals. The US EPA develops and uses models based on (quantitative) structure-activity relationships ([Q]SARs) to estimate critical parameters. As in any evolving field, (Q)SARs have experienced successes, suffered failures, and responded to emerging trends. Correlations of a chemical structure with its properties or biological activity were first demonstrated in the late 19(th) century and today have been encapsulated in a myriad of quantitative and qualitative SARs. The development and proliferation of the personal computer in the late 20(th) century gave rise to a quickly increasing number of property estimation models, and continually improved computing power and connectivity among researchers via the internet are enabling the development of increasingly complex models.

    L'objectif était d’évaluer les aspects épidémiologiques des violences conjugales, identifier les facteurs de risques et les différents types de violences conjugales, évaluer les conséquences des violences conjugales sur la santé des victimes, afin d'améliorer la prise en charge des victimes et la prévention du phénomène. Il s'est agit d'une étude transversale effectuée de décembre 2012 à janvier 2013 à Dakar. Les données ont été recueillies, après consentement, sur fiche d'enquête anonyme soumise à toute personne volontaire vivant en couple et résidant à Dakar. L'analyse statistique a été effectuée avec le logiciel SPSS 13.0. Le nombre de personnes victimes de violences conjugales était de 60 soit 37,30% dont 31 femmes (51,70%) et 29 hommes (48,30%). Le sex-ratio était de 0,93. Parmi les victimes, 53 étaient scolarisées soit 88,30%. Le régime matrimonial était de type monogame dans 39 cas (65%) et polygame dans 21 cas (35%). La vie en couple durait depuis moins de 11 ans dans 60% des cas et durait de 11 ans à 20 ans au plus dans 26,6% des cas. L’étude des types de violences montrait la fréquence des agressions physiques. Les armes utilisées étaient surtout les armes naturelles. Les principaux facteurs de risque de violence conjugale sont les facteurs sociodémographiques, culturels et économiques comme le jeune âge, l'inégalité du genre, les jeunes couples, la précarité, le niveau d'instruction élevé. La prise en charge des victimes et la prévention du phénomène restent insuffisantes dans nos pays. PMID:26918077

  2. The role of integrated resource planning, environmental externalities, and anticipation of future regulation in compliance planning under the Clean Air Act Amendments of 1990

    1993-07-01

    Utilities are developing sulfur dioxide (SO{sub 2}) emission compliance plans to meet limitations of the Clean Air Act Amendments of 1990 (CAAA). Compliance plans will have long-term effects on resource selection, fuel choice, and system dispatch. Use of integrated resource planning (IRP) is necessary to ensure compliance plans are consistent with the overall societal goals. In particular, environmental externalities must be integrated with the compliance planning process. The focus of the CAAA is on air pollution reduction, specifically acid gases and toxics, and attainment of National Ambient Air Quality Standards (NAAQS) for criteria pollutants. Title IV specifically focuses on sulfur dioxide with a national allowance trading system, while further regulation of toxics and nitrogen oxides is slated for additional study. Yet, compliance planning based narrowly upon today`s environmental regulations could fail to meet the broad goals of IRP if a larger array of environmental externalities is excluded from the analysis. Compliance planning must consider a broad range of environmental effects from energy production and use to (1) protect society`s long-term stake in environmental quality, and (2) ensure that today`s plans are rich enough to accommodate potential changes in regulation and national environmental goals. The explicit recognition of environmental effects, such as those associated with CO{sub 2} release, will result in prudent compliance plans that take advantage of current opportunities for pollution avoidance and have long-term viability in the face of regulatory change. By including such considerations, the mix of resources acquired and operated (supply and demand, existing and new, conventional and renewable, fuel type and fuel quality, pollution control, and dispatch protocols) will be robust and truly least-cost.

    The organization called "Les Impatients" was founded in 1992. Using a unique model, Les Impatients welcomes those with mental health issues who would like to express themselves through art. Les Impatients offers free creative workshops and encourages exchanges with the community through the sharing of its participants' creations. The name Les Impatients reinforces the idea that the organization does not consider those attending its workshops as patients, but rather creators who are eager to heal, develop their craft and find their place in society. The participants contribute to the collective objective of breaking down the stigma that surrounds mental illness.Les Impatients collaborates with various mental health organizations in Quebec, such as the Institut universitaire en santé mentale de Montréal (IUSMM) affiliated to the Université de Montréal, Douglas Mental Health University Institute (DMHUI), the Centre de santé et services sociaux Drummond (CSSS Drummond) and the Centre de santé et services sociaux Pierre-Boucher (CSSS Pierre-Boucher). Les Impatients offers more than 48 workshops in eight different locations to around 450 participants each week.Dissemination activities, remarkable events, original projects: Les Impatients stands out through its realizations. Examples are exhibitions, collections of love letters, comic books, CD, concerts, and reading nights. The organization's originality resides in the exploration of the links between the work of the participants and that of professional artists. An illustration of this interest is the annual Parle-moi d'amour auction-exhibition, which has been one of Les Impatients' major events since 1999.As part of its mission, Les Impatients conserves the works of art created by the participants during the workshops. Its collection includes more than 15,000 works of art from Les Impatients as well as pieces donated by collectors of unconventional art, commonly known as "art brut" or "outsider art". The

    Les plaies du tendon patellaire sont peu fréquentes et sont peu rapportés dans la littérature, contrairement aux ruptures sous cutanées. Les sections du tendon patellaire nécessitent une réparation immédiate afin de rétablir l'appareil extenseur et de permettre une récupération fonctionnelle précoce. A travers ce travail rétrospectif sur 13 cas, nous analysons les aspects épidémiologiques, thérapeutiques et pronostiques de ce type de pathologie en comparant différents scores. L’âge moyen est de 25 ans avec une prédominance masculine. Les étiologies sont dominées par les accidents de la voie publique (68%) et les agressions par agent tranchant (26%) et contendant (6 %). Tous nos patients ont bénéficié d'un parage chirurgical avec suture tendineuse direct protégée par un laçage au fils d'aciers en légère flexion. La rééducation est débutée après sédation des phénomènes inflammatoires. Au dernier recul les résultats sont excellents et bon à 92%. Nous n'avons pas noté de différence de force musculaire et d'amplitude articulaire entre le genou sain et le genou lésé. Les lésions ouvertes du tendon patellaire est relativement rare. La prise en charge chirurgicale rapide donne des résultats assez satisfaisants. La réparation est généralement renforcée par un semi-tendineux, synthétique ou métallique en forme de cadre de renfort pour faciliter la réadaptation et réduire le risque de récidive après la fin de l'immobilisation.

    This paper presents the results of an activity by the Large Eddy Simulation (LES) Working Group of the AIAA Fluid Dynamics Technical Committee to (1) address the current capabilities of LES, (2) outline recommended practices and key considerations for using LES, and (3) identify future research needs to advance the capabilities and reliability of LES for analysis of turbulent flows. To address the current capabilities and future needs, a survey comprised of eleven questions was posed to LES Working Group members to assemble a broad range of perspectives on important topics related to LES. The responses to these survey questions are summarized with the intent not to be a comprehensive dictate on LES, but rather the perspective of one group on some important issues. A list of recommended practices is also provided, which does not treat all aspects of a LES, but provides guidance on some of the key areas that should be considered.

  7. Validating LES for Jet Aeroacoustics

    2011-01-01

    Engineers charged with making jet aircraft quieter have long dreamed of being able to see exactly how turbulent eddies produce sound and this dream is now coming true with the advent of large eddy simulation (LES). Two obvious challenges remain: validating the LES codes at the resolution required to see the fluid-acoustic coupling, and the interpretation of the massive datasets that result in having dreams come true. This paper primarily addresses the former, the use of advanced experimental techniques such as particle image velocimetry (PIV) and Raman and Rayleigh scattering, to validate the computer codes and procedures used to create LES solutions. It also addresses the latter problem in discussing what are relevant measures critical for aeroacoustics that should be used in validating LES codes. These new diagnostic techniques deliver measurements and flow statistics of increasing sophistication and capability, but what of their accuracy? And what are the measures to be used in validation? This paper argues that the issue of accuracy be addressed by cross-facility and cross-disciplinary examination of modern datasets along with increased reporting of internal quality checks in PIV analysis. Further, it is argued that the appropriate validation metrics for aeroacoustic applications are increasingly complicated statistics that have been shown in aeroacoustic theory to be critical to flow-generated sound.

  12. La violence sur les réseaux canadiens de télévision

    Paquette, Guy

    2003-01-01

    La question des effets de la violence à la télévision occupe une place très importante dans l’opinion publique depuis les vingt dernières années, et des centaines d’études y ont été consacrées. Plusieurs chercheurs concluent à une influence négative de cette violence sur le comportement. Le public, les diffuseurs et les autorités politiques ont tous endossé l’idée de réduire la quantité totale de violence présentée au petit écran – en particulier dans les émissions accessibles aux enfants. Nous avons analysé un millier d’émissions de fiction présentées entre 1993 et 2001 sur les principaux réseaux généralistes de télévision au Canada : TVA et TQS ainsi que CTV et Global pour les réseaux privés français et anglais, ainsi que Radio-Canada français et anglais pour les réseaux publics. La méthodologie utilisée est l’analyse de contenu classique, où l’acte de violence constitue l’unité d’analyse. Les données recueillies démontrent que la quantité de violence a augmenté régulièrement depuis 1993, malgré la volonté affirmée des télédiffuseurs de présenter une programmation moins violente. C’est le cas du nombre brut d’actes et du nombre d’actes à l’heure, qui est lui aussi en forte croissance. Les réseaux privés véhiculent trois fois plus de violence que les réseaux publics. On constate également qu’une très forte proportion d’actes de violence figure dans des émissions qui commencent avant 21 h, et que de nombreux enfants y sont probablement exposés. Nous signalons finalement la place de plus en plus importante occupée par la violence psychologique. PMID:20020031

    Résumé Question Alors que le diagnostic d’appendicite aigu est relativement simple à poser, celui d’appendicite chronique peut être controversé et souvent mal posé. De quelle manière et à quel moment les cliniciens devraient-ils investiguer l’appendicite chronique comme la cause de douleurs abdominales chroniques et récidivantes dans la population pédiatrique? Réponse L’appendicite chronique est une inflammation ou fibrose de longue date de l’appendice dont le tableau clinique est une douleur abdominale prolongée ou intermittente. Son diagnostic est souvent difficile à poser et elle peut entraîner des complications telles que des infections intra-abdominales, ou l’occlusion ou la perforation de l’intestin. Le tableau clinique, de même que les études d’imagerie, peuvent aider le clinicien à écarter d’autres affections, et chez les patients qui reçoivent un diagnostic, dont de nombreux enfants, l’appendicectomie soulage partiellement ou complètement la douleur.

    La douleur induite par les soins correspond à la douleur survenant lors des actes à visé diagnostique et/ou thérapeutique. A notre connaissance, nous n'avons pas encore des données disponibles pour les douleurs induites par les soins à l'Hôpital de Befelatanana. Nos objectifs étaient de décrire le profil épidémiologique de la douleur induite par les soins, d'identifier les principaux facteurs influençant sur l'intensité de la douleur et leurs retentissements chez les patients. Il s'agissait d'une étude rétrospective, transversale type un jour donné menée dans les douze services de Médecines au Centre Hospitalier Universitaire de Befelatanana en Novembre 2013. Cent deux patients ont été retenus dans l’étude et trois cent vingt trois actes douloureux étaient enregistrés. La fréquence de la douleur induite par les soins était de 69,86%. Le genre féminin prédominait dans 52% des cas (n = 53) avec un sex-ratio à 0,92. L’âge moyen était de 46 ans. Les ponctions vasculaires étaient l'acte prédominant dans 49,54% (n = 109) des cas. Les infirmiers réalisaient les soins dans 47,05% (n = 48) des cas. L'information verbale était la mesure préventive utilisée dans 57,84% des cas (n = 59). Le transport par marche à pied et au dos représentait 16,67% des cas (n = 17). Les patients naïfs des gestes étaient plus anxieux. Ces patients gardaient de mauvais souvenir dans 64,71% des cas (n = 66). La fréquence de douleur induite par les soins était trop élevée. Un effort important est nécessaire pour réduire la douleur induite par les soins PMID:25932071

    Résumé But : La cryptorchidie est une pathologie assez fréquente en urologie. Elle est associée à un risque élevé d’infertilité et de dégénérescence. Elle semble aussi être associée à un risque important de torsion. Cette entité est très peu abordée dans la littérature. Nous rapportons tous les cas de torsion sur testicule cryptorchide observés à notre service dans le but de mieux caractériser cette pathologie et de réduire ainsi le taux d’orchidectomies. Méthodologie : Il s’agit d’une étude rétrospective portant sur tous les cas de torsion sur testicule cryptorchide opérés dans notre service d’urologie entre 1999 et 2007. Les patients ont fait l’objet d’une description basée sur le résumé de leurs observations. Résultats : Les patients étaient âgés de 7 mois à 39 ans. La torsion touchait le testicule droit dans 53 % des cas. Le tableau clinique comportait une douleur au niveau de la région inguinale d’apparition soudaine avec une masse sous-cutanée inflammatoire et douloureuse à ce niveau et surtout un hémiscrotum homolatéral vide. Dans 60 % des cas, le diagnostic était tardif et une orchidectomie a été réalisée. Dans les autre cas, un abaissement du testicule a été réalisé avec orchidopexie controlatéral dans le même temps opératoire. Conclusion : Bien qu’il s’agisse d’une pathologie peu courante, la torsion sur testicule cryptorchide doit être étudiée davantage. Le diagnostic précoce permettra de sauver et d’abaisser le testicule et faciliter ainsi le dépistage d’une éventuelle dégénérescence. PMID:21191497

  19. Future contraceptives.

    PubMed

    Alexander, N J

    1995-09-01

    This article looks at the improvements that may occur in contraceptives in the near future. While no product currently under study would be ideal (highly effective, safe, readily reversible, free of side effects, coitally independent, counteract the spread of sexually transmitted diseases, and inexpensive), several would come closer than those available today. For men, the condom is the only currently available contraception, and a thinner version has recently been introduced in response to the criticism that condoms reduce sexual pleasure. Methods under study for men include manipulating hormones to halt sperm production by the intramuscular injection of an androgen in combination with a progestin or by blocking the activity of gonadotropin-releasing hormone. In the future, long-acting reversible agents should be available to directly halt sperm production or maturation. In men and women, vaccines should become available that would use antibodies to disrupt reproduction. Additional hormonal options in women should include hormone-releasing vaginal rings, a simplified contraceptive implant delivery system, a hormone-releasing IUD, and a monthly pill. Vaginal chemicals could be used to impede some of the necessary changes that sperm undergo after ejaculation. Spermicides will also be available with the ability to prevent STDs. The order of appearance of these new contraceptives will probably be nonlatex condoms, vaginal rings, and new implants, followed by disease-reducing spermicides, hormone-releasing IUDs, new emergency contraceptives, a three-month injectable for men, biodegradable implants for women, and immunocontraceptives (if they receive the backing of the industry).

  2. Swimming microorganisms acting as nanorobots versus artificial nanorobotic agents: A perspective view from an historical retrospective on the future of medical nanorobotics in the largest known three-dimensional biomicrofluidic networks

    Martel, Sylvain

    2016-01-01

    The vascular system in each human can be described as a 3D biomicrofluidic network providing a pathway close to approximately 100 000 km in length. Such network can be exploited to target any parts inside the human body with further accessibility through physiological spaces such as the interstitial microenvironments. This fact has triggered research initiatives towards the development of new medical tools in the form of microscopic robotic agents designed for surgical, therapeutic, imaging, or diagnostic applications. To push the technology further towards medical applications, nanotechnology including nanomedicine has been integrated with principles of robotics. This new field of research is known as medical nanorobotics. It has been particularly creative in recent years to make what was and often still considered science-fiction to offer concrete implementations with the potential to enhance significantly many actual medical practices. In such a global effort, two main strategic trends have emerged where artificial and synthetic implementations presently compete with swimming microorganisms being harnessed to act as medical nanorobotic agents. Recognizing the potentials of each approach, efforts to combine both towards the implementation of hybrid nanorobotic agents where functionalities are implemented using both artificial/synthetic and microorganism-based entities have also been initiated. Here, through the main eras of progressive developments in this field, the evolutionary path being described from some of the main historical achievements to recent technological innovations is extrapolated in an attempt to provide a perspective view on the future of medical nanorobotics capable of targeting any parts of the human body accessible through the vascular network.

  4. Les médicaments à libération prolongée pour les enfants et les adolescents ayant un trouble de déficit de l’attention avec hyperactivité

    PubMed Central

    Feldman, M; Bélanger, S

    2009-01-01

    Le trouble de déficit de l’attention avec hyperactivité (TDAH) touche un enfant canadien sur 20 et s’associe à un dossier scolaire et à un registre d’emploi défavorables, à des taux élevés de blessures et de consommation de drogues ou d’alcool, à des relations interpersonnelles médiocres, à de mauvaises issues en santé mentale et à une qualité de vie insatisfaisante. Des essais contrôlés démontrent que les médica-ments sont efficaces pour traiter les symptômes de TDAH tandis que des études d’observation indiquent qu’ils s’associent à de meilleures issues sociales et de santé. De nombreuses familles, ainsi que leur médecin traitant, préfèrent les médicaments à libération prolongée (LP) contre le TDAH aux médicaments à libération immédiate (LI) et à action brève. Toutefois, les préparations à LP sont souvent inabor-dables pour les familles, dont un nombre disproportionné fait partie de la strate à faible statut socioéconomique. Le présent document de principes vise à proposer une évaluation critique des données probantes sur l’efficacité relative des médicaments à LP par rapport aux médicaments à LI ainsi que des recommandations au sujet de leur utilisation convenable dans le traitement du TDAH. Lorsque les médicaments sont indiqués, il faut envisager d’utiliser des préparations à LP comme traitement de première intention contre le TDAH parce qu’elles sont plus efficaces et moins susceptibles d’être détournées. Les futures recherches et les analyses coûts-avantages doivent tenir compte à la fois de l’efficacité de médicaments dans des études contrôlées et de leur efficacité clinique en situation réelle ainsi que du potentiel de détournement et de mésusage de ces médicaments. L’industrie, les sociétés d’assurance et le gouvernement doivent collaborer pour rendre ces médicaments accessibles à tous les enfants et adolescents ayant un TDAH.

  8. Anisotropic grid adaptation in LES

    Toosi, Siavash; Larsson, Johan

    2016-11-01

    The modeling errors depend directly on the grid (or filter) spacing in turbulence-resolving simulations (LES, DNS, DES, etc), and are typically at least as significant as the numerical errors. This makes adaptive grid-refinement complicated, since it prevents the estimation of the local error sources through numerical analysis. The present work attempts to address this difficulty with a physics-based error-source indicator that accounts for the anisotropy in the smallest resolved scales, which can thus be used to drive an anisotropic grid-adaptation process. The proposed error indicator is assessed on a sequence of problems, including turbulent channel flow and flows in more complex geometries. The formulation is geometrically general and applicable to complex geometries.

  14. Les Johnson Views Interstellar Sail Material

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Engineers at Marshall Space Flight Center's (MSFC) Interstellar Propulsion Research department are proposing different solutions to combustion propellants for future space travel. One alternative being tested is the solar sail. The idea is, once deployed, the sail will allow solar winds to propel a spacecraft away from Earth and towards its destination. This would allow a spacecraft to travel indefinitely without the need to refuel during its ong journey. Thin reflective sails could be propelled through space by sunlight, microwave beams, or laser beams, just as the wind pushes sailboats on Earth. The sail will be the largest spacecraft ever built, sparning 440 yards, twice the diameter of the Louisiana Super Dome. Construction materials are being tested in a simulated space environment, where they are exposed to harsh conditions to test their performance and durability in extremely hot and cold temperatures. A leading candidate for the construction material is a carbon fiber material whose density is less than 1/10 ounce per square yard, the equivalent of flattening one raisin to the point that it covers a square yard. In space, the material would unfurl like a fan when it is deployed from an expendable rocket. This photo shows Les Johnson, manager of MSFC's Interstellar Propulsion Research Center holding the rigid, lightweight carbon fiber. An artist's concept of the sail is on the right. Mankind's first venture outside of our solar system is proposed for launch in a 2010 timeframe. An interstellar probe, powered by the fastest spacecraft ever flown, will zoom toward the stars at 58 miles per second. It will cover the distance from New York to Los Angeles in less than a minute and will travel over 23 billion miles beyond the edge of the solar system.

  16. Les Elements Legers: Diffusion dans les Enveloppes Stellaires et Implications Cosmologiques

    NASA Astrophysics Data System (ADS)

    Richer, Jacques

    1992-01-01

    Les observations des abondances des elements legers (Z <= 5) sont utilisees pour estimer la quantitie de lithium qui a ete produite lors du Big -Bang, et obtenir simultanement des contraintes sur la nature des inhomogeneites qui ont pu exister durant la nucleosynthese primordiale. Nous utilisons un modele simple capable de simuler approximativement la diffusion et la retro-diffusion des neutrons a travers la matiere inhomogene durant les premieres minutes de l'expansion de l'Univers. Nous tenons compte de la difference possible entre l'abondance primordiale de Li et les abondances observees dans les plus vieilles etoiles. Cette difference (un facteur 2, environ) est estimee en construisant des modeles evolutifs d'etoiles peu massives de Population II, incluant la sedimentation gravitationnelle du lithium et de l'helium. Ces modeles montrent egalement que les ages des vieux amas stellaires sont grandement surestimes lorsqu'ils sont determines a partir de modeles stellaires n'incluant pas l'effet de la diffusion de He. Nous calculons ensuite comment evoluent les abondances de Li et Be dans des etoiles plus massives et plus jeunes, de la pre-sequence principale ou de la ZAMS, jusqu'a l'epuisement de leur hydrogene central. Les modeles incluent la sedimentation simultanee de l'helium a travers l'enveloppe. Une approche hierarchique (evolution du coeur--evolution de l'enveloppe --tri des elements traces) est utilisee pour simuler efficacement le grand nombre d'etoiles necessaire pour la construction d'isochrones. Une attention particuliere est portee aux consequences de la sedimentation de He sur l'etendue des zones convectives, et sur la diffusion de Li et Be. Les forces radiatives agissant sur ces deux elements sont calculees en detail a partir des donnees atomiques. Les etoiles simulees correspondent approximativement aux types spectraux A, F, et AmFm. Les abondances de Li et Be observees dans les etoiles jeunes de ces types sont comparees a nos predictions dans le

    Résumé Objectif Présenter des recommandations sur la prise en charge de l’infection gonococcique chez les adultes et les jeunes. Qualité des données Les recommandations thérapeutiques des lignes directrices canadiennes sur les infections transmissibles sexuellement reposent sur une recherche documentaire de même que sur des catégories de recommandations et des niveaux de qualité de données déterminés par au moins 2 évaluateurs. Les recommandations ont été revues par des pairs et sont en instance d’approbation par le groupe de travail d’experts. Message principal Les nouvelles recommandations portant sur la prise en charge de l’infection gonococcique chez les adultes et les jeunes préconisent les cultures à titre d’outil diagnostique lorsqu’elles sont pratiques, le traitement par antibiothérapie combinée (ceftriaxone associée à l’azithromycine) et le signalement sans délai de tous les cas dont le traitement a échoué aux autorités de santé publique. Conclusion Si elles sont suivies, ces nouvelles recommandations pourraient réduire l’échec thérapeutique, contribuer à une surveillance plus étroite des tendances à la résistance de Neisseria gonorrhoeae aux antibiotiques et contribuer à prévenir la transmission de gonorrhée résistante à plusieurs médicaments.

    Résumé Objectif Guider les médecins de famille dans l’élaboration de plans de dépistage et de traitements préventifs à l’intention de leurs patients âgés. Sources de l’information Une recension a été effectuée dans la base de données MEDLINE pour trouver des lignes directrices canadiennes sur les soins de santé primaires et les personnes âgées; des lignes directrices, des méta-analyses, des guides de pratique clinique ou des révisions systématiques portant sur le dépistage de masse chez les 80 ans et plus et les aînés fragiles, se limitant à ceux publiés entre 2006 et juillet 2016; et des articles sur les services de santé préventifs à l’intention des aînés et présentant un intérêt pour la pratique familiale ou les médecins de famille, limités à ceux publiés en anglais entre 2012 et juillet 2016. Message principal L’estimation de l’espérance de vie n’est pas une science facile ou précise, mais la fragilité est un concept émergent susceptible d’être utile à cet égard. Le Groupe d’étude canadien sur les soins de santé préventifs propose des lignes directrices sur le dépistage du cancer, mais elles sont moins précises en ce qui concerne les patients de plus de 74 ans et il faut donc individualiser les plans de prise en charge. L’estimation des années de vie qui restent aide à orienter vos recommandations concernant les plans de dépistage et de traitements préventifs. Les risques augmentent souvent proportionnellement avec la fragilité et la comorbidité. D’autre part, les bienfaits diminuent souvent à mesure que l’espérance de vie raccourcit. Les plans de prise en charge préventive devraient tenir compte des points de vue du patient et être convenus d’un commun accord.

    The USA has a rich history of public health efforts to reduce morbidity and mortality from tobacco use. Comprehensive tobacco-prevention programmes, when robustly implemented, reduce the prevalence of youth and adult smoking, decrease cigarette consumption, accelerate declines in tobacco-related deaths, and diminish health-care costs from tobacco-related diseases. Effective public health interventions include raising the price of tobacco products, smoke-free policies, counter-marketing campaigns, advertising restrictions, augmenting access to treatment for tobacco use through insurance coverage and telephone help lines, and comprehensive approaches to prevent children and adolescents from accessing tobacco products. The US Food and Drug Administration (FDA) has six major areas of regulatory authority: regulation of tobacco products; regulation of the advertising, marketing, and promotion of tobacco products; regulation of the distribution and sales of tobacco products; enforcement of the provisions of the Tobacco Control Act and tobacco regulations; regulatory science to support FDA authorities and activities; and public education about the harms of tobacco products and to support FDA regulatory actions. With passing of the Family Smoking Prevention and Tobacco Control Act (Tobacco Control Act) in June, 2009, important new regulatory approaches were added to the tobacco prevention and control arsenal.

    With the introduction of the Medicare Access and Children's Health Insurance Program Reauthorization Act, clinicians who are not eligible for an exemption must choose to participate in 1 of 2 new reimbursement models: the Merit-based Incentive Payment System or Alternative Payment Models (APMs). Although most dermatologists are expected to default into the Merit-based Incentive Payment System, some may have an interest in exploring APMs, which have associated financial incentives. However, for dermatologists interested in the APM pathway, there are currently no options other than joining a qualifying Accountable Care Organization, which make up only a small subset of Accountable Care Organizations overall. As a result, additional APMs relevant to dermatologists are needed to allow those interested in the APMs to explore this pathway. Fortunately, the Medicare Access and Children's Health Insurance Program Reauthorization Act establishes a process for new APMs to be approved and the creation of bundled payments for skin diseases may represent an opportunity to increase the number of APMs available to dermatologists. In this article, we will provide a detailed review of APMs under the Medicare Access and Children's Health Insurance Program Reauthorization Act and discuss the development and introduction of APMs as they pertain to dermatology.

    1998-04-01

    In radiation therapy, it is important to know precisely the dose distribution in the target volume and in the critical organs. To be clinically applicable, the dose calculation models must account for the actual characteristics of the beams and for the tissue densities. An accuracy of 2% in low dose gradient regions and 2mm in high dose gradient is expected, while keeping the computation time consistent with an interactive approach. We describe and discuss briefly the dose calculation models currently used. En radiothérapie, il est indispensable d'avoir une connaissance précise de la dose délivrée dans le volume cible et dans les organes critiques avoisinants. Pour être utilisables cliniquement, les modèles de calcul doivent tenir compte des caractéristiques exactes des faisceaux utilisés et des densités des tissus. Une précision de l'ordre de 2% dans les régions à faible gradient de dose, et de 2mm dans les régions à fort gradient est nécessaire tout en conservant un temps de calcul compatible avec une approche interactive. Les modèles de calcul utilisés sont ici succintement décrits et commentés.

  6. Merging RANS & LES approaches in submesoscale modeling

    2010-09-01

    Merging LES and RANS simulation is important for extending the application range of mesoscale models to the sub-mesoscale. Hence many traditional mesoscale modeling groups are currently working on adding LES capabilities to their models. To investigate the differences, which occur by switching from RANS to LES approaches, simulations with the METRAS and METRAS-LES (Fock, 2007) are presented. These differences are investigated in terms of effects caused by the choice of the computational grid and the sub-grid scale closures. Simulations of convective boundary layers on two different grids are compared to investigate the influence of vertical grid spacing and extension. One simulation is carried out on a high-resolution vertical homogeneous grid and the other with a vertical stretched grid, which has coarser resolution in higher altitudes. The stretched grid is vertical defined, as it would be done in the standard setup for the mesoscale model. Hence, this investigation shows to what amount the eddy resolving capabilities of a LES model is effected by the transition of the grid to a grid, which is vertically the same as typically used in mesoscale modeling. The differences, which occur by using different approaches for subgrid scale turbulence, are quantified and compared with the effects caused by the computational grid. Additional some details of the used LES SGS closure (Deardorff, 1980) are investigated. These details deal on evaluating the importance of the reduced characteristic filter length scale for stable stratification. But the main focus is on comparing RANS and LES and discussion of combination in a mixed turbulence scheme, which applies a the LES closure in the atmospheric boundary layer and a RANS based turbulence model in the stable atmosphere above.

    As the implementation of the Medicare Access and Children's Health Insurance Program Reauthorization Act begins, many dermatologists who provide Medicare Part B services will be subject to the reporting requirements of the Merit-based Incentive Payment System (MIPS). Clinicians subject to MIPS will receive a composite score based on performance across 4 categories: quality, advancing care information, improvement activities, and cost. Depending on their overall MIPS score, clinicians will be eligible for a positive or negative payment adjustment. Quality will replace the Physician Quality Reporting System and clinicians will report on 6 measures from a list of over 250 options. Advancing care information will replace meaningful use and will assess clinicians on activities related to integration of electronic health record technology into their practice. Improvement activities will require clinicians to attest to completion of activities focused on improvements in care coordination, beneficiary engagement, and patient safety. Finally, cost will be determined automatically from Medicare claims data. In this article, we will provide a detailed review of the Medicare Access and Children's Health Insurance Program Reauthorization Act with a focus on MIPS and briefly discuss the potential implications for dermatologists.

    The NASA Advanced Communications Technology Satellite (ACTS) was conceived to help maintain U.S. leadership in the world's communications-satellite market. This experimental satellite is expected to be launched by NASA in 1992 and to furnish the technology necessary for establishing very small aperture terminal digital networks which provide on-demand full-mesh connectivity, and 1.544-MBPS services with only a single hop. Utilizing on-board switching and processing, each individual voice or data circuit can be separately routed to any location in the network. This paper provides an overview of the ACTS and discusses the value of the technology for future communications systems.

  11. Federal Employees' Compensation Act.

    2009-01-01

    The Federal Employees' Compensation Act (FECA) program provides wage loss compensation and payments for medical treatment to federal civilian employees. Administered by the Department of Labor (DOL), FECA covers over 2.7 million federal employees in more than 70 different agencies. FECA costs rose from $1.4 billion in 1990 to $2.6 in 2006, while the federal workforce remained essentially unchanged. While federal civilian employees represent only 2.1% of all workers eligible for workers' compensation benefits, federal programs account for 6% of the benefits paid. Disability benefits under FECA are far greater than those in the state workers' compensation programs. The benefit payments often exceed the former salary of the injured employee. The last congressional hearings on the FECA program were held over thirty years ago. It is unlikely that Congressional review will occur any time soon, as the entrenched bureaucracy that benefits from the FECA program defines and protects its future.

    In the last decade, the demand for reliable data, voice, and video satellite communication links between aircraft and ground to improve air traffic control, airline management, and to meet the growing demand for passenger communications has increased significantly. It is expected that in the near future, the spectrum required for aeronautical communication services will grow significantly beyond that currently available at L-band. In anticipation of this, JPL is developing an experimental broadband aeronautical satellite communications system that will utilize NASA's Advanced Communications Technology Satellite (ACTS) as a satellite of opportunity and the technology developed under JPL's ACTS Mobile Terminal (AMT) Task to evaluate the feasibility of using K/Ka-band for these applications. The application of K/Ka-band for aeronautical satellite communications at cruise altitudes is particularly promising for several reasons: (1) the minimal amount of signal attenuation due to rain; (2) the reduced drag due to the smaller K/Ka-band antennas (as compared to the current L-band systems); and (3) the large amount of available bandwidth. The increased bandwidth available at these frequencies is expected to lead to significantly improved passenger communications - including full-duplex compressed video and multiple channel voice. A description of the proposed broadband experimental system will be presented including: (1) applications of K/Ka-band aeronautical satellite technology to U.S. industry; (2) the experiment objectives; (3) the experiment set-up; (4) experimental equipment description; and (5) industrial participation in the experiment and the benefits.

  15. A Test of the Validity of Inviscid Wall-Modeled LES

    2015-11-01

    Computational expense is one of the main deterrents to more widespread use of large eddy simulations (LES). As such, it is important to reduce computational costs whenever possible. In this vein, it may be reasonable to assume that high Reynolds number flows with turbulent boundary layers are inviscid when using a wall model. This assumption relies on the grid being too coarse to resolve either the viscous length scales in the outer flow or those near walls. We are not aware of other studies that have suggested or examined the validity of this approach. The inviscid wall-modeled LES assumption is tested here for supersonic flow over a flat plate on three different grids. Inviscid and viscous results are compared to those of another wall-modeled LES as well as experimental data - the results appear promising. Furthermore, the inviscid assumption reduces simulation costs by about 25% and 39% for supersonic and subsonic flows, respectively, with the current LES application. Recommendations are presented as are future areas of research. This work used the Extreme Science and Engineering Discovery Environment (XSEDE), which is supported by National Science Foundation grant number ACI-1053575. Computational resources on TACC Stampede were provided under XSEDE allocation ENG150001.

  18. Le point sur les amas de galaxies

    Pierre, M.

    Clusters of galaxies: a review After having briefly described the 3 main components of clusters of galaxies (dark matter, gas and galaxies) we shall present clusters from a theoretical viewpoint: they are the largest entities known in the universe. Consequently, clusters of galaxies play a key role in any cosmological study and thus, are essential for our global understanding of the universe. In the general introduction, we shall outline this fundamental aspect, showing how the study of clusters can help to constrain the various cosmological scenarios. Once this cosmological framework is set, the next chapters will present a detailed analysis of cluster properties and of their cosmic evolution as observed in different wavebands mainly in the optical (galaxies), X-ray (gas) and radio (gas and particles) ranges. We shall see that the detailed study of a cluster is conditioned by the study of the interactions between its different components; this is the necessary step to ultimately derive the fundamental quantity which is the cluster mass. This will be the occasion to undertake an excursion into extremely varied physical processes such as the multi-phase nature of the intra-cluster medium, lensing phenomena, starbursts and morphology evolution in cluster galaxies or the interaction between the intra-cluster plasma and relativistic particles which are accelerated during cluster merging. For each waveband, we shall outline simply the dedicated observing and analysis techniques, which are of special interest in the case of space observations. Finally, we present several ambitious projects for the next observatory generation as well as their expected impact on the study of clusters of galaxies. Après avoir brièvement décrit les 3 constituants fondamentaux des amas de galaxies (matière noire, gaz et galaxies) nous présenterons les amas d'un point de vue plus théorique : ce sont les entités les plus massives à l'équilibre connues dans l'univers.

    Summary A travers une revue de la littérature, cet article se propose d'exposer les particularités des troubles respiratoires chez le brûlé. Ces troubles sont liés à un mécanisme direct, lorsque l'arbre respiratoire est lésé par le transfert d'énergie thermique du à la brûlure et/ou par un mécanisme indirect, lorsque la fonction respiratoire et ventilatoire du poumon est perturbée par les phénomènes loco-régionaux ou généraux du brûlé. Ces troubles respiratoires sont aggravés par l'inhalation des gaz contenus dans la fumée d'incendie. Le diagnostic de ces troubles est clinique et paraclinique. Il doit être précoce et continu. Les patients nécessitent de différents moyens thérapeutiques tels que l'oxygénothérapie, la libération des voies respiratoires, l'amélioration de la mécanique ventilatoire et de la fonction respiratoire, l'antibiothérapie ou la chirurgie des séquelles. Cette prise en charge doit nécessairement être multidisciplinaire. PMID:21991224

Cette periode de demarrage et d'organisation, traitee dans la deuxieme partie de la these, se termine en 1947-48, au moment ou l'OER et les cooperatives raffermissent leur maitrise du systeme cooperatif d'electrification rurale. Les annees 1948 a 1955 (troisieme partie de these) correspondent a une periode de croissance pour le mouvement cooperatif. Cette partie scrute ainsi le developpement des cooperatives, les vastes chantiers de construction et l'injection de millions de dollars dans l'electrification rurale. Cette troisieme partie prend egalement acte des premiers signes que quelque chose ne va pas si bien dans le monde cooperatif. Nous y verrons egalement les ruraux a l'oeuvre: comme membres, d'abord, mais aussi en tant que benevoles, puis a l'emploi des cooperatives. La quatrieme et derniere partie, les annees 1956 a 1964, aborde les changements majeurs qui ont cours dans l'univers cooperatif; il s'agit d'une ere nouvelle et difficile pour le mouvement cooperatif, dont les reseaux paraissent inadaptes aux changements de profil de la consommation d'electricite des usagers. L'OER sent alors le besoin de raffermir son controle des cooperatives, car il pressent les problemes et les defis auxquels elles auront a faire face. Notre etude se termine par l'acquisition des cooperatives par Hydro-Quebec, en 1963-64. Fondee sur des sources riches et variees, notre demarche propose un eclairage inedit sur une dimension importante de l'histoire de l'electricite au Quebec. Elle permet, ce faisant, de saisir les rouages et l'action de l'Etat sous un angle particulier, avant sa profonde transformation amorcee au cours des annees 1960. De meme, elle apporte quelques cles nouvelles pour une meilleure comprehension de la dynamique des milieux ruraux de cette periode.

Type d’étude Il s’agit d’une étude mixte intégrant un questionnaire auto-administré et des entrevues qualitatives. La banque de données administratives des actes médicaux de la Régie de l’assurance maladie du Québec a aussi été analysée. Contexte La province de Québec. Participants Un total de 1415 omnipraticiens de différents lieux de pratiques ont été sollicités pour le questionnaire; 970 ont été rejoints. Un sous-groupe de 60 omnipraticiens a été rejoint pour les entrevues. Principaux paramètres à l'étude La prévalence annuelle des consultations reliées à des TM courants (TMC) ou graves (TMG), les pratiques cliniques, les pratiques de collaboration, les facteurs facilitant ou entravant la prise en charge des TM, ainsi que les recommandations pour l’amélioration du système de soins. Résultats Le taux de réponse a été de 41% (n = 398 omnipraticiens) pour le questionnaire et de 63% (n = 60) pour les entrevues. Environ 25 % des visites chez les omnipraticiens sont associées à des TM. Presque tous les omnipraticiens prennent en charge des TMC et se sentent compétents pour le faire, à l’inverse de la situation retrouvée pour les TMG. Près de 20 % des TMC sont référés (principalement à des intervenants psychosociaux), alors que près de 75 % des TMG sont référés (surtout en psychiatrie et à l’urgence). Plus de 50 % des omnipraticiens affirment n’entretenir aucun contact avec l’une ou l’autre des ressources de santé mentale. Plusieurs facteurs influencent la prise en charge des TM: les profils des patients (complexité des TM, troubles concomitants); les caractéristiques des omnipraticiens (réseau informel, formation); la culture professionnelle (travail en silo, mécanismes cliniques formalisés); le milieu institutionnel (multidisciplinarité, salariat); l’organisation des

    2009-01-01

    A report presents a study addressing the question of which large-eddy simulation (LES) equations are appropriate for modeling the flow of evaporating drops of a multicomponent liquid in a gas (e.g., a spray of kerosene or diesel fuel in air). The LES equations are obtained from the direct numerical simulation (DNS) equations in which the solution is computed at all flow length scales, by applying a spatial low-pass filter. Thus, in LES the small scales are removed and replaced by terms that cannot be computed from the LES solution and instead must be modeled to retain the effect of the small scales into the equations. The mathematical form of these models is a subject of contemporary research. For a single-component liquid, there is only one LES formulation, but this study revealed that for a multicomponent liquid, there are two non-equivalent LES formulations for the conservation equations describing the composition of the vapor. Criteria were proposed for selecting the multicomponent LES formulation that gives the best accuracy and increased computational efficiency. These criteria were applied in examination of filtered DNS databases to compute the terms in the LES equations. The DNS databases are from mixing layers of diesel and kerosene fuels. The comparisons resulted in the selection of one of the multicomponent LES formulations as the most promising with respect to all criteria.

    NASA recently restructured its Space Communications Program to emphasize the development of high risk communication technology useable in multiple frequency bands and to support a wide range of future communication needs. As part of this restructuring, the Advanced Communications Technology Satellite (ACTS) Project will develop and experimentally verify the technology associated with multiple fixed and scanning beam systems which will enable growth in communication satellite capacities and more effective utilization of the radio frequency spectrum. The ACTS requirements and operations as well as the technology significance for future systems are described.

    Acting internships are an important component of modern day medical school curriculum. Several specialties outside of internal medicine now offer acting internship experiences to fourth year medical students. We have found that a dermatology acting internship is a valuable experience for fourth year medical students who are interested in pursuing a residency in dermatology. Our experience with the dermatology acting internship over the 2010-2011 academic year is described.

    2013-01-01

    Résumé Question Les pleurs sont communs chez les nourrissons; par ailleurs, prendre soin d'un nourrisson dont les pleurs sont inconsolables et qu'on surnommait aussi auparavant des coliques ou un reflux, peut souvent causer une détresse extrême aux parents. Le recours à un agent de suppression de l'acide gastrique (p. ex. les inhibiteurs de la pompe à protons [IPP]) est-il bénéfique chez ces nourrissons? Réponse On utilise de plus en plus les IPP chez les nourrissons et les enfants depuis quelques années. L'efficacité des inhibiteurs de la pompe à protons n'a pas été démontrée dans le traitement de l'irritabilité et des pleurs excessifs chez des enfants autrement en santé de moins de 3 mois. D'autre part, si les IPP sont généralement bien tolérés, il existe certaines données probantes reliant l'utilisation des IPP avec une susceptibilité accrue aux gastroentérites aiguës, à la pneumonie acquise dans la communauté et à des troubles de l'utilisation et de l'absorption des nutriments. Indépendamment des traitements, les pleurs et l'irritabilité durant la tendre enfance s'améliorent généralement avec le temps. Entre-temps, les inhibiteurs de la pompe à protons n'améliorent pas les symptômes.

  17. Analysis of discretization errors in LES

    NASA Technical Reports Server (NTRS)

    Ghosal, Sandip

    1995-01-01

    All numerical simulations of turbulence (DNS or LES) involve some discretization errors. The integrity of such simulations therefore depend on our ability to quantify and control such errors. In the classical literature on analysis of errors in partial differential equations, one typically studies simple linear equations (such as the wave equation or Laplace's equation). The qualitative insight gained from studying such simple situations is then used to design numerical methods for more complex problems such as the Navier-Stokes equations. Though such an approach may seem reasonable as a first approximation, it should be recognized that strongly nonlinear problems, such as turbulence, have a feature that is absent in linear problems. This feature is the simultaneous presence of a continuum of space and time scales. Thus, in an analysis of errors in the one dimensional wave equation, one may, without loss of generality, rescale the equations so that the dependent variable is always of order unity. This is not possible in the turbulence problem since the amplitudes of the Fourier modes of the velocity field have a continuous distribution. The objective of the present research is to provide some quantitative measures of numerical errors in such situations. Though the focus of this work is LES, the methods introduced here can be just as easily applied to DNS. Errors due to discretization of the time-variable are neglected for the purpose of this analysis.

  18. Progress Towards an LES Wall Model Including Unresolved Roughness

    NASA Astrophysics Data System (ADS)

    Craft, Kyle; Redman, Andrew; Aikens, Kurt

    2015-11-01

    Wall models used in large eddy simulations (LES) are often based on theories for hydraulically smooth walls. While this is reasonable for many applications, there are also many where the impact of surface roughness is important. A previously developed wall model has been used primarily for jet engine aeroacoustics. However, jet simulations have not accurately captured thick initial shear layers found in some experimental data. This may partly be due to nozzle wall roughness used in the experiments to promote turbulent boundary layers. As a result, the wall model is extended to include the effects of unresolved wall roughness through appropriate alterations to the log-law. The methodology is tested for incompressible flat plate boundary layers with different surface roughness. Correct trends are noted for the impact of surface roughness on the velocity profile. However, velocity deficit profiles and the Reynolds stresses do not collapse as well as expected. Possible reasons for the discrepancies as well as future work will be presented. This work used the Extreme Science and Engineering Discovery Environment (XSEDE), which is supported by National Science Foundation grant number ACI-1053575. Computational resources on TACC Stampede were provided under XSEDE allocation ENG150001.

  19. RANS and LES simulations of the airflow through nasal cavities

    NASA Astrophysics Data System (ADS)

    Lamberti, Giacomo

    2015-11-01

    The prediction of detailed flow patterns in nasal cavities using computational fluid dynamics (CFD) can provide essential information on the potential relationship between patient-specific geometrical characteristics and health problems. The long-term goal of the OpenNOSE project is to develop a reliable open-source computational tool based on the OpenFOAM CFD toolbox that can assist surgeons in their daily practice. The objective of this study was to investigate the effect of the turbulence model and boundary conditions on simulations of the airflow in nasal cavities. The geometry, including paranasal sinuses, was reconstructed from a carefully selected CT scan, and RANS and LES simulations were carried out for steady inspiration and expiration. At a flow rate near 20 l/min, the flow is laminar in most of the domain. During the inspiration phase, turbulence develops in nasopharynx and oropharynx regions; during the expiration phase, another vortical region is observed down the nostrils. A comparison between different boundary conditions suggests the use of a total pressure condition, or alternatively a uniform velocity, at the inlet and outlet. In future work the same geometry will be used for setting up a laboratory experiment, intended to cross-validate the numerical results.

    Résumé Question Je vois de plus en plus d’enfants et d’adolescents qui souffrent de céphalées pouvant se classer dans la catégorie des migraines. J’ai fait des lectures sur le sumatriptan par voie intranasale comme thérapie abortive. Est-ce un traitement efficace? Réponse La migraine aiguë chez les enfants et les adolescents est fréquente et difficile à traiter. Le sumatriptan intranasal est une option sûre et généralement efficace pour les enfants et les adolescents. La dose actuellement recommandée est de 20 mg pour les enfants qui pèsent plus de 40 kg et de 10 mg pour ceux dont le poids se situe entre 20 et 39 kg. Il faudrait faire des études de plus grande envergure pour contrecarrer les limitations des échantillons de petite taille et mieux comprendre la faible concentration plasmique et les effets placebo observés dans les études jusqu’à présent.

  2. LES: A General Expert System And Its Applications

    NASA Astrophysics Data System (ADS)

    Perkins, W. A.; Laffey, T. J.

    1984-06-01

    The Lockheed Expert System (LES) has been designed to help knowledge engineers quickly solve problems in diagnosing, monitoring, planning, designing, checking, guiding, and interpreting. In its first application, LES was used to guide less-experienced maintenance personnel in the fault diagnosis of a large signal-switching network containing Built-In Test Equipment (BITE). LES used not only the knowledge of the expert diagnostician (captured in the familiar form of "IF-THEN" rules), but also knowledge about the structure, function, and causal relations of the device under study to perform rapid isolation of the module causing the failure. In addition to aiding the engineer in troubleshooting an electronic device, LES can also explain its reasoning and actions to the user, and can provide extensive database retrieval and graphics capabilities. In this paper we show how both the structure of the device and the troubleshooting rules of the expert are conveniently represented using LES's case grammar format. Also, an actual troubleshooting session between a user and LES is presented. By adding goals, rules, database information, and a few special procedures to the general LES framework, we were able to have a working system in a much shorter time (four man-months) than would have been possible starting afresh. The current status of the system is that it has been fielded and is under evaluation. LES is now being applied in other domains which include design checking and photo-interpretation.

  6. Les superpolynomes symetriques dans les problemes a plusieurs corps de la mecanique quantique supersymetrique

    NASA Astrophysics Data System (ADS)

    Desrosiers, Patrick

    S'inspirant de la supersymetrie, on construit dans cette these une nouvelle generalisation de la theorie des fonctions symetriques. Une theorie physique est supersymetrique si: (1) elle contient des bosons (particules de spin entier) et des fermions (particules de spin demi-entier); (2) elle reste inchangee suite a une transformation des bosons en fermions et vice versa. Les fonctions symetriques dans le superespace (superfonctions symetriques) incorporent a la fois des variables commutatives (bosoniques) et anticommutatives (fermioniques). Ces dernieres engendrent une algebre de Grassmann. Une superfonction symetrique est invariante sous l'echange simultane des variables bosoniques et fermioniques (action diagonale du groupe symetrique); elle se caracterise par une superpartition, i.e., une juxtaposition appropriee de partitions usuelles d'entiers non negatifs. On utilise deux approches dans l'elaboration de la theorie des superfonctions symetriques: l'une provient de la combinatoire et l'autre, de la physique. Suivant la premiere approche, on obtient l'extension des elements standards de la theorie des fonctions symetriques fonctions monomiales, fonctions symetriques elementaires, fonctions completement symetriques, series de puissances, fonctions generatrices et formules de Cauchy. On demontre egalement qu'il existe une extension naturelle, a un parametre, du produit scalaire combinatoire defini par l'orthogonalite des series de puissances dans le superespace. La seconde approche consiste a resoudre des problemes a N corps de la mecanique quantique supersymetrique. On etudie les extensions supersymetriques des modeles Calogero-Moser-Sutherland (CMS), lesquels decrivent l'evolution de particules dont le potentiel d'inter action est proportionnel a l'inverse du carre de la distance separant les particules. Deux modeles supersymetriques CMS sont resolus: trigonometrique (sur un cercle) et rationnel (sur une ligne) avec confinement harmonique. Leurs fonctions d

    2001-01-01

    Il s'agit ici d'un apercu des résultats sur les Noyaux Actifs de Galaxies (AGNs) obtenus grace `a la nouvelle génération de satellites X: Chandra & XMM-Newton. Pour la première fois, grace `a leurs caractéristiques instrumentales (sensibilité, résolutions angulaire et spectrale) des images et des spectres de qualité sans précédent sont obtenus dans le domaine des rayons X pour les objets extragalactiques comme les Noyaux Actifs de Galaxies. Notamment une étude spectroscopique fine est dorénavant possible ce qui permet d'appliquer de puissants diagnostics de plasmas comme notamment ceux basés sur les raies des ions héliumoides qui donnent une estimation précise de la densité, de la température, ainsi que la mise en évidence des processus d'ionisation (photoionisation et/ou ionisation collisionnelle) qui dominent dans les plasmas chauds (e.g. "Warm Absorber") des AGNs. La sensibilité de XMM-Newton permet d'étudier les AGNs à très grands redshifts et/ou très fortement absorbés. La résolution angulaire (0.5") de Chandra permet d'étudier séparément les différentes composantes de ces objets: le noyau, le milieu chaud environnant ("Warm Absorber"), les jets, ainsi que le milieu interstellaire et les objets ponctuelles (binaires X, candidats trous noirs, restes de Supernovae,...) de la galaxie hôte. Cette nouvelle ère dans le domaine des rayons X va permettre de fortement contraindre les paramètres physiques, géométriques, dynamiques ainsi que la localisation de la matière accrétante autour des trous noirs supermassifs, dans les différents types d'AGNs (Seyfert, quasars Radio-Loud et Radio-Quiet, noyaux actifs dans les amas de galaxies), en relation avec les autres composantes observées dans les autres domaines de longueurs d'onde (radio, optique, UV, etc...). Ceci s'inscrit dans un objectif plus vaste de compréhension de l'évolution de l'ensemble des galaxies qui pour la plupart semblent contenir un trou noir supermassif en leur

  18. ACTS Satellite Telemammography Network Experiments

    NASA Technical Reports Server (NTRS)

    Kachmar, Brian A.; Kerczewski, Robert J.

    2000-01-01

    The Satellite Networks and Architectures Branch of NASA's Glenn Research Center has developed and demonstrated several advanced satellite communications technologies through the Advanced Communications Technology Satellite (ACTS) program. One of these technologies is the implementation of a Satellite Telemammography Network (STN) encompassing NASA Glenn, the Cleveland Clinic Foundation. the University of Virginia, and the Ashtabula County Medical Center. This paper will present a look at the STN from its beginnings to the impact it may have on future telemedicine applications. Results obtained using the experimental ACTS satellite demonstrate the feasibility of Satellite Telemammography. These results have improved teleradiology processes and mammography image manipulation, and enabled advances in remote screening methodologies. Future implementation of satellite telemammography using next generation commercial satellite networks will be explored. In addition, the technical aspects of the project will be discussed, in particular how the project has evolved from using NASA developed hardware and software to commercial off the shelf (COTS) products. Development of asymmetrical link technologies was an outcome of this work. Improvements in the display of digital mammographic images, better understanding of end-to-end system requirements, and advances in radiological image compression were achieved as a result of the research. Finally, rigorous clinical medical studies are required for new technologies such as digital satellite telemammography to gain acceptance in the medical establishment. These experiments produced data that were useful in two key medical studies that addressed the diagnostic accuracy of compressed satellite transmitted digital mammography images. The results of these studies will also be discussed.

    I show that the quantum measurement problem can be understood if the measurement is seen as a "speech act" in the sense of modern language theory. The reduction of the state vector is in this perspective an intersubjective -- or, better, a-subjective -- symbolic process. I then give some perspectives on applications to the "Mind-Body Problem".

    PubMed

    Erickson, David L; Kress, W John

    2012-01-01

    It is a risky task to attempt to predict the direction that DNA barcoding and its applications may take in the future. In a very short time, the endeavor of DNA barcoding has gone from being a tool to facilitate taxonomy in difficult to identify species, to an ambitious, global initiative that seeks to tackle such pertinent and challenging issues as quantifying global biodiversity, revolutionizing the forensic identifications of species, advancing the study of interactions among species, and promoting the reconstruction of evolutionary relationships within communities. The core element of DNA barcoding will always remain the same: the generation of a set of well-identified samples collected and genotyped at one or more genetic barcode markers and assembled into a properly curated database. But the application of this body of data will depend on the creativity and need of the research community in using a "gold standard" of annotated DNA sequence data at the species level. We foresee several areas where the application of DNA barcode data is likely to yield important evolutionary, ecological, and societal insights, and while far from exclusive, provide examples of how DNA barcode data will continue to empower scientists to address hypothesis-driven research. Three areas of immediate and obvious concern are (1) biodiversity inventories, (2) phylogenetic applications, and (3) species interactions.

  1. Future food.

    PubMed

    Wahlqvist, Mark L

    2016-12-01

    Food systems have changed markedly with human settlement and agriculture, industrialisation, trade, migration and now the digital age. Throughout these transitions, there has been a progressive population explosion and net ecosystem loss and degradation. Climate change now gathers pace, exacerbated by ecological dysfunction. Our health status has been challenged by a developing people-environment mismatch. We have regarded ecological conquest and innovative technology as solutions, but have not understood how ecologically dependent and integrated we are. We are ecological creatures interfaced by our sensoriness, microbiomes, shared regulatory (endocrine) mechanisms, immune system, biorhythms and nutritional pathways. Many of us are 'nature-deprived'. We now suffer what might be termed ecological health disorders (EHD). If there were less of us, nature's resilience might cope, but more than 9 billion people by 2050 is probably an intolerable demand on the planet. Future food must increasingly take into account the pressures on ecosystem-dependent food systems, with foods probably less biodiverse, although eating in this way allows optimal health; energy dysequilibrium with less physical activity and foods inappropriately energy dense; and less socially-conducive food habits. 'Personalised Nutrition', with extensive and resource-demanding nutrigenomic, metabolomic and microbiomic data may provide partial health solutions in clinical settings, but not be justified for ethical, risk management or sustainability reasons in public health. The globally prevalent multidimensional malnutritional problems of food insecurity, quality and equity require local, regional and global action to prevent further ecosystem degradation as well as to educate, provide sustainable livelihoods and encourage respectful social discourse and practice about the role of food.

    The Americans with Disabilities Act gives all Americans with disabilities a chance to achieve the same quality of life that individuals without disabilities enjoy. This act prohibits discrimination on the basis of disabilities in employment, public services, privately operated public accommodations, services, and telecommunications. The Americans with Disabilities Act is divided into five titles. Title I of the act pertains to discrimination against the disabled in the workplace. Title II prevents discrimination against persons with a disability in state and local government services. Title III prohibits discrimination against persons with disabilities in places of public accommodations and commercial facilities. Title IV ensures that companies offering telephone services to the general public provide special services for individuals with hearing and speech impairments. Under the enforcement provisions of the Americans with Disabilities Act, stringent penalties will be implemented for failure to comply with its provisions.

  7. Wall-resolved LES of high Reynolds number airfoil flow near stall condition for wall modeling in LES: LESFOIL revisited

    NASA Astrophysics Data System (ADS)

    Asada, Kengo; Kawai, Soshi

    2016-11-01

    Wall-resolved large-eddy simulation (LES) of an airfoil flow involving a turbulent transition and separations near stall condition at a high Reynolds number 2.1 x 106 (based on the freestream velocity and the airfoil chord length) is conducted by using K computer. This study aims to provide the wall-resolved LES database including detailed turbulence statistics for near-wall modeling in LES and also to investigate the flow physics of the high Reynolds number airfoil flow near stall condition. The LES well predicts the laminar separation bubble, turbulent reattachment and turbulent separation. The LES also clarified unsteady flow features associated with shear-layer instabilities: high frequency unsteadiness at St = 130 at the laminar separation bubble near the leading edge and low frequency unsteadiness at St = 1.5 at the separated turbulent shear-layer near the trailing edge. Regarding the near-wall modeling in LES, the database indicates that the pressure term in the mean streamwise-momentum equation is not negligible at the laminar and turbulent separated regions. This fact suggests that widely used equilibrium wall model is not sufficient and the inclusion of the pressure term is necessary for wall modeling in LES of such flow. This research used computational resources of the K computer provided by the RIKEN Advanced Institute for Computational Science through the HPCI System Research project (Project ID: hp140028). This work was supported by KAKENHI (Grant Number: 16K18309).

    The present experiment was designed to establish the effects of acts of kindness and acts of novelty on life satisfaction. Participants aged 18-60 took part on a voluntary basis. They were randomly assigned to perform either acts of kindness, acts of novelty, or no acts on a daily basis for 10 days. Their life satisfaction was measured before and after the 10-day experiment. As expected, performing acts of kindness or acts of novelty resulted in an increase in life satisfaction.

  9. Draconian dress act repealed.

    PubMed

    Mhone, C

    1994-01-01

    The Dress Act was put into place in Malawi by the government of President Kamuzu Banda after the long period of direct colonialism. The act made it illegal for women in Malawi to be seen publicly wearing dresses which did not completely cover their knees or wearing pants; men had to wear their hair short. Police officers even scrutinized women's attire at private house parties and in homes. The autocratic political structure established by Banda, however, was voted out in a referendum June 14, 1993. Pressure by opposition forces such as the United Democratic Front forced a repeal of the act on November 16 of the same year. The repeal was vigorously attacked by female Parliament members as a move which would result in moral degradation and an increase in the level of sexual harassment against women. Other citizens and tourists have generally detested the act. The act has most certainly kept many potential visitors from vacationing in Malawi. Some expert observers think that repeals of the Dress Act, the Forfeiture Act, and legislation which allowed the government to detain opposition figures without trial were done to garner support from the Paris Club for the resumption of balance of payments support suspended due to the country's poor human rights record.

  10. The Genetic Privacy Act and commentary

    1995-02-28

    The Genetic Privacy Act is a proposal for federal legislation. The Act is based on the premise that genetic information is different from other types of personal information in ways that require special protection. The DNA molecule holds an extensive amount of currently indecipherable information. The major goal of the Human Genome Project is to decipher this code so that the information it contains is accessible. The privacy question is, accessible to whom? The highly personal nature of the information contained in DNA can be illustrated by thinking of DNA as containing an individual`s {open_quotes}future diary.{close_quotes} A diary is perhaps the most personal and private document a person can create. It contains a person`s innermost thoughts and perceptions, and is usually hidden and locked to assure its secrecy. Diaries describe the past. The information in one`s genetic code can be thought of as a coded probabilistic future diary because it describes an important part of a unique and personal future. This document presents an introduction to the proposal for federal legislation `the Genetic Privacy Act`; a copy of the proposed act; and comment.

Sources de l’information On a fait une recension dans Ovid MEDLINE à l’aide des expressions dementia, Alzheimer disease, community health services utilization et caregiver stress. Message principal Il a été démontré qu’il est bénéfique aux patients et aux aidants si le diagnostic de la démence est posé tôt dans la maladie. Une consultation auprès de la Société Alzheimer peut aider dans la prise en charge non pharmacologique de la démence au moment du diagnostic et en tout temps durant l’évolution de la maladie. Parmi les services offerts, on peut mentionner des renseignements au sujet de la démence, le soutien aux aidants, la coordination des services communautaires et une grande diversité de ressources écrites à l’intention des patients et des aidants. Là où il est offert, le programme Premier lien peut aider avec l’orientation vers des services en minimisant la nécessité pour les patients ou les aidants de communiquer eux-mêmes avec les filiales locales de la Société. On discute aussi d’autres ressources, y compris les soins de répit et les approches technologiques pour prendre en charge l’errance. Conclusion La Société Alzheimer joue un rôle important dans la prise en charge de la démence et les médecins de famille devraient toujours envisager d’y référer leurs patients au moment du diagnostic, quelle que soit la gravité de l’état. Premier lien, quand il est accessible, peut faciliter le contact avec les services. Des ressources comme les soins de répit et les programmes de jour devraient toujours être considérés lorsqu’ils sont disponibles.

  14. LES tests on airfoil trailing edge serration

    NASA Astrophysics Data System (ADS)

    Zhu, Wei Jun; Shen, Wen Zhong

    2016-09-01

    In the present study, a large number of acoustic simulations are carried out for a low noise airfoil with different Trailing Edge Serrations (TES). The Ffowcs Williams-Hawkings (FWH) acoustic analogy is used for noise prediction at trailing edge. The acoustic solver is running on the platform of our in-house incompressible flow solver EllipSys3D. The flow solution is first obtained from the Large Eddy Simulation (LES), the acoustic part is then carried out based on the instantaneous hydrodynamic pressure and velocity field. To obtain the time history data of sound pressure, the flow quantities are integrated around the airfoil surface through the FWH approach. For all the simulations, the chord based Reynolds number is around 1.5x106. In the test matrix, the effects from angle of attack, the TE flap angle, the length/width of the TES are investigated. Even though the airfoil under investigation is already optimized for low noise emission, most numerical simulations and wind tunnel experiments show that the noise level is further decreased by adding the TES device.

  15. Coupling Turbulence in Hybrid LES-RANS Techniques

    2011-01-01

    A formulation is proposed for hybrid LES-RANS computations that permits accurate computations during resolution changes, so that resolution may be changed at will in order to employ only as much resolution in each subdomain as is required by the physics. The two components of this formulation, establishing the accuracy of a hybrid model at constant resolutions throughout the RANS-to-LES range and maintaining that accuracy when resolution is varied, are demonstrated for decaying, homogeneous, isotropic turbulence.

    1993-01-01

    Over the last decade, the demand for reliable mobile satellite communications (satcom) for voice, data, and video applications has increased dramatically. As consumer demand grows, the current spectrum allocation at L-band could become saturated. For this reason, NASA and the Jet Propulsion Laboratory are developing the Advanced Communications Technology Satellites (ACTS) mobile terminal (AMT) and are evaluating the feasibility of K/Ka-band (20/30 GHz) mobile satcom to meet these growing needs. U.S. industry and government, acting as co-partners, will evaluate K/Ka-band mobile satcom and develop new technologies by conducting a series of applications-oriented experiments. The ACTS and the AMT testbed will be used to conduct these mobile satcom experiments. The goals of the ACTS Mobile Experiments Program and the individual experiment configurations and objectives are further presented.

  18. Protection des ions organiques contre les dommages induits a l'ADN par les electrons de basse energie

    NASA Astrophysics Data System (ADS)

    Dumont, Ariane

    Il a ete demontre que les electrons de basse energie (EBE) peuvent induire des cassures simple brin (CSB) a l'ADN, via la formation d'anions transitoires qui decroissent par attachement dissociatif, ou dans d'autres etats electroniques dissociatifs menant a la fragmentation. Afin d'effectuer une etude complete des effets des electrons de basse energie sur la matiere biologique, il est necessaire de comprendre leur mecanismes d'interaction non seulement avec l'ADN, mais avec les constituants de son environnement. Les histones sont une composante importante de l'environnement moleculaire de l'ADN. Leur charge positive leur permet de s'associer aux groupements phosphate anionique de l'ADN. Le role principal de ces proteines basiques consiste a organiser l'ADN et l'empaqueter afin de former la chromatine. Les cations sont une autre composante importante de la cellule; ils jouent un role dans la stabilisation de la conformation B de l'ADN in vitro par leurs interactions avec les petits et grands sillons de l'ADN, ainsi qu'avec le groupement phosphate charge negativement. Avec les histones, ils participent egalement a la compaction de l'ADN pour former la chromatine. Cette etude a pour but de comprendre comment la presence d'ions organiques (sous forme de Tris et d'EDTA) a proximite de l'ADN modifie le rendement de cassures simple brin induit par les electrons de basse energie. Le Tris et l'EDTA ont-ete choisis comme objet d'etude, puisqu'en solution, ils forment le tampon standard pour solubiliser l'ADN dans les experiences in vitro (10mM Tris, 1mM EDTA). De plus, la molecule Tris possede un groupement amine alors que l'EDTA possede 4 groupements carboxyliques. Ensembles, ils peuvent se comporter comme un modele simple pour les acides amines. Le ratio molaire de 10 :1 de Tris par rapport a l'EDTA a pour but d'imiter le comportement des histones qui sont riches en arginine et lysine, acides amines possedant un groupement amine charge positivement additionnel.

    2000-01-01

    This viewgraph presentation gives an overview of the future of computational fluid dynamics (CFD), which in the past has pioneered the field of flow simulation. Over time CFD has progressed as computing power. Numerical methods have been advanced as CPU and memory capacity increases. Complex configurations are routinely computed now and direct numerical simulations (DNS) and large eddy simulations (LES) are used to study turbulence. As the computing resources changed to parallel and distributed platforms, computer science aspects such as scalability (algorithmic and implementation) and portability and transparent codings have advanced. Examples of potential future (or current) challenges include risk assessment, limitations of the heuristic model, and the development of CFD and information technology (IT) tools.

    2016-11-01

    BCM (Building Cube Method) enables high-resolution CFD (Computational Fluid Dynamics) simulation by high parallelization performance. This study discusses the applicability of LES (Large Eddy Simulation) based on BCM to prediction of wind velocity and pressure around various building blocks in urban area. First, we validate the computed results of flows past 3D square cylinder in turbulent boundary layer. Fundamental accuracy of the surface pressure distribution on square cylinder is investigated by high-resolution BCM simulation with IBM (Immersed Boundary Method). Next, the BCM is applied to flow simulation of real urban area (Domain size: 25x12km). As a result of this simulation, the development process of urban boundary layer from coastal area to Tokyo central area is examined. Accordingly we show the present numerical model based on BCM-LES can represent sufficiently spatially fine structures and temporally unsteady fluctuations of turbulent flows with good accuracy. It is clarified that the complex pressure distributions acting on the buildings have been also reproduced from the sense of wind-resistance design of buildings in cities

  6. Hydrogeologic uncertainties and policy implications: The Water Consumer Protection Act of Tucson, Arizona, USA

    NASA Astrophysics Data System (ADS)

    Wilson, L. G.; Matlock, W. G.; Jacobs, K. L.

    The 1995 Water Consumer Protection Act of Tucson, Arizona, USA (hereafter known as the Act) was passed following complaints from Tucson Water customers receiving treated Central Arizona Project (CAP) water. Consequences of the Act demonstrate the uncertainties and difficulties that arise when the public is asked to vote on a highly technical issue. The recharge requirements of the Act neglect hydrogeological uncertainties because of confusion between "infiltration" and "recharge." Thus, the Act implies that infiltration in stream channels along the Central Wellfield will promote recharge in the Central Wellfield. In fact, permeability differences between channel alluvium and underlying basin-fill deposits may lead to subjacent outflow. Additionally, even if recharge of Colorado River water occurs in the Central Wellfield, groundwater will become gradually salinized. The Act's restrictions on the use of CAP water affect the four regulatory mechanisms in Arizona's 1980 Groundwater Code as they relate to the Tucson Active Management Area: (a) supply augmentation; (b) requirements for groundwater withdrawals and permitting; (c) Management Plan requirements, particularly mandatory conservation and water-quality issues; and (d) the requirement that all new subdivisions use renewable water supplies in lieu of groundwater. Political fallout includes disruption of normal governmental activities because of the demands in implementing the Act. Résumé La loi de 1995 sur la protection des consommateurs d'eau de Tucson (Arizona, États-Unis) a été promulguée à la suite des réclamations des consommateurs d'eau de Tucson alimentés en eau traitée à partir à la station centrale d'Arizona (CAP). Les conséquences de cette loi montrent les incertitudes et les difficultés qui apparaissent lorsque le public est appeléà voter sur un problème très technique.

    1992-01-01

    The Advanced Communications Technology Satellite (ACTS) to be launched in 1993 is briefly introduced. Its multibeam antenna, consisting of electrically similar 30 GHz receive and 20 GHz transmit offset Cassegrain systems, both utilizing orthogonal polarizations, is described. Dual polarization is achieved by using one feed assembly for each polarization in conjunction with nested front and back subreflectors, the gridded front subreflector acting as a window for one polarization and a reflector for the other. The antennas produce spot beams with approximately 0.3 degree beamwidth and gains of approximately 50 dbi. High surface accuracy and high edge taper produce low sidelobe levels and high cross-polarization isolation. A brief description is given of several Ka-band components fabricated for ACTS. These include multiflare antenna feedhorns, beam-forming networks utilizing latching ferrite waveguide switches, a 30 GHz HEMT low-noise amplifier and a 20 GHz TWT power amplifier.

    L'aspergillome pulmonaire est une colonisation par Aspergillus d'une cavité pulmonaire préformée. Nos objectifs étaient de définir le profil épidémio-clinique et thérapeutique des aspergillomes pulmonaires et essayer de dégager les facteurs favorisants de cette affection à Madagascar. Nous avons réalisés une étude prospective, descriptive, analytique durant 59 mois sur les aspergillomes pulmonaires à Antananarivo Madagascar. Etaient inclus dans cette étude les malades ayant un diagnostic d'aspergillome pulmonaire. Trente-sept (37) cas d'aspergillome pulmonaire étaient recensés parmi les 8 392 patients hospitalisés dans le service de Pneumologie (0,44%). Il s'agit de 29 hommes (78,38%) et 8 femmes (21,61%), d’âge moyen de 43 ans. Les facteurs prédisposant étaient dominés par la tuberculose pulmonaire (89,19%). Le délai moyen d'apparition de l'aspergillome chez les malades ayant un antécédent de tuberculose pulmonaire à bacilloscopie positive (TPM+) était de 8 ans et 6 mois avec un délai extrême de un mois à 23 ans. L'hémoptysie était le mode de révélation le plus fréquent (91,89%). Le traitement était médical chez 27 patients (72,97%) et médico-chirurgical chez 10 patients (27,03%). Vingt sept patients étaient perdus de vue (72,97%), et pour les 10 patients suivis (27,02%), 70% avaient une évolution favorable avec disparition des signes, et 30% présentaient des hémoptysies récidivantes. Le taux de mortalité postopératoire était de 4% et 50% des patients avaient des complications postopératoires. La surveillance des lésions séquellaires de tuberculose pulmonaire qui constituent les facteurs favorisants prédominant d'aspergillome pulmonaire à Madagascar nécessite une attention particulière. La prise en charge de la tuberculose doit être précoce et adaptée surtout dans les pays à forte prévalence tuberculeuse. PMID:22187586

Source des données Les études qui évaluent les paramètres pondéraux dans la population sont en majorité observationnelles. Des données probantes de niveau I ont été publiées pour évaluer l’influence des interventions relatives au poids sur la mortalité et la qualité de vie. Message principal Seulement un petit pourcentage des personnes qui désirent perdre du poids réussissent à le faire de manière durable. La mortalité est la plus faible chez les personnes se situant dans la catégorie de poids élevé-normal et surpoids. La trajectoire pondérale la plus sécuritaire est la stabilité du poids avec une optimisation de la condition physique et métabolique. Il est démontré que la mortalité est plus faible chez les personnes ayant des comorbidités reliées à l’obésité si elles perdent du poids. Il est aussi établi que la qualité de vie sur le plan de la santé est meilleure chez les personnes obèses qui perdent du poids. Par contre, la perte de poids chez une personne obèse autrement en santé est associée à une mortalité accrue. Conclusion La perte de poids est recommandable seulement chez les personnes qui ont des comorbidités reliées à l’obésité. Les personnes obèses en santé qui veulent perdre du poids devraient être informées qu’il peut y avoir des risques à le faire. Une stratégie qui se traduit par un indice de masse corporelle stable avec une condition physique et métabolique optimisée, peu importe le poids, est l’option d’intervention la plus sécuritaire en ce qui concerne le poids.

    The Patient Protection and Affordable Care Act of 2010 (PPACA), although a subject of much debate in the Unites States, was enacted on March 23, 2010, and upheld by the Supreme Court on June 28, 2012. This act advocates that "healthcare is a right, not a privilege." The main goals of PPACA are to minimize the number of uninsured Americans and make healthcare available to everyone at an affordable price. The Congressional Budget Office has determined that 94% of Americans will have healthcare coverage while staying under the $900 billion limit that President Barack Obama established by bending the healthcare cost curve and reducing the deficit over the next 10 years.

  12. Les nerfs à fleur de peau.

    PubMed

    Misery, L

    2002-04-01

    Skin innervation is extremely dense and reaches the most superficial layers of the epidermis (but not into the stratum corneum). The relationship between skin and the nervous system was neglected for a long time. Nowadays, this represents one of the most widely investigated fields of skin biology. Associations between nerve fibres and skin are so close that these can be observed at the cellular level. They are anatomical and physiological. Neurotransmitters are naturally synthesized by nerve endings, but cells from the skin and the immune system are also able to produce them. They are mediators for transmission of information between skin and the nervous system. All cutaneous and immune cells express specific receptors for these neuromediators, and enzymes for degrading them. Binding of the neurotransmitter to its receptor induces modulation of cell properties and skin functions (immunity, cell differentiation and proliferation, pigmentation, etc.). Hence, keratinocytes, Langerhans cells, melanocytes, endothelial cells, fibroblasts and the other cells of the skin or the immune system are modulated and controlled by the nerves. Reciprocally, skin is able to modulate neuronal activity and growth. All these data suggest that skin, nervous and immune systems are integrated in a unique system that we could name the neuro-immuno-cutaneous system (NICS). Hence, we can understand how the nervous system, and further the psychism, are involved in the maintenance of cutaneous homeostasis. In dermatological diseases or in cosmetological disorders, this equilibrium is broken. New fields of research are open: neuro-dermatology and of course neuro-cosmetics. Neuro-cosmetic products are supposed to modulate NICS functioning at the epidermal level. The French expression 'avoir les nerfs à fleur de peau' means that nervosity is so tense that one feels his nerves closely under or within skin, ready to explode. In fact, nerves are always 'à fleur de peau'. Skin is an organ whose

    Three SIMVAL LES calculations were completed this quarter: {phi} (equivalence ratio) of (1) 0.55, (2) 0.625, and (3) 0.7. The predictions were first analyzed, and then compared to existing experimental data of pressure dynamics, NO{sub x}, and CO emissions. It appears that the combustor flowfield changes for the {phi} of 0.55 case (compared to the other two cases), and this flowfield change results in a slight reduction in the pressure dynamics compared to the {phi} of 0.625 case. The predicted pressure rms values were 1.0 psi or less for the three cases. Good agreement was seen between predicted and measured NO{sub x} emissions for the cases with {phi} = 0.55 and {phi} = 0.625. The CO predictions were higher than the measurements, but possible reasons were identified. A new SIMVAL dataset recorded June, 2004, is being processed and will be transmitted to CFDRC in the near future. The previous two datasets had known deficiencies. This new dataset will be compared to the LES predictions in the next quarter.

    2014-12-01

    Two science-arts approaches are emerging as effective means to convey "futurethinking" to learners: systems gaming and experiential futures. FutureCoast exemplifies the latter: by engaging participants with voicemails supposedly leaking from the cloud of possible futures, the storymaking game frames the complexities of climate science in relatable contexts. Because participants make the voicemails themselves, FutureCoast opens up creative ways for people to think about possibly climate-changed futures and personal ways to talk about them. FutureCoast is a project of the PoLAR Partnership with a target audience of informal adult learners primarily reached via mobile devices and online platforms. Scientists increasingly use scenarios and storylines as ways to explore the implications of environmental change and societal choices. Stories help people make connections across experiences and disciplines and link large-scale events to personal consequences. By making the future seem real today, FutureCoast's framework helps people visualize and plan for future climate changes. The voicemails contributed to FutureCoast are spread through the game's intended timeframe (2020 through 2065). Based on initial content analysis of voicemail text, common themes include ecosystems and landscapes, weather, technology, societal issues, governance and policy. Other issues somewhat less frequently discussed include security, food, industry and business, health, energy, infrastructure, water, economy, and migration. Further voicemail analysis is examining: temporal dimensions (salient time frames, short vs. long term issues, intergenerational, etc.), content (adaptation vs. mitigation, challenges vs. opportunities, etc.), and emotion (hopeful, resigned, etc. and overall emotional context). FutureCoast also engaged audiences through facilitated in-person experiences, geocaching events, and social media (Tumblr, Twitter, Facebook, YouTube). Analysis of the project suggests story

    Critical issues involved in large eddy simulation (LES) experiments relate to the treatment of unresolved subgrid scale flow features and required initial and boundary condition supergrid scale modelling. The inherently intrusive nature of both LES and laboratory experiments is noted in this context. Flow characterization issues becomes very challenging ones in validation and computational laboratory studies, where potential sources of discrepancies between predictions and measurements need to be clearly evaluated and controlled. A special focus of the discussion is devoted to turbulent initial condition issues.

  20. Hydrogeology in North America: past and future

    NASA Astrophysics Data System (ADS)

    Narasimhan, T. N.

    2005-03-01

    This paper is a retrospective on the evolution of hydrogeology in North America over the past two centuries, and a brief speculation of its future. The history of hydrogeology is marked by developments in many different fields such as groundwater hydrology, soil mechanics, soil science, economic geology, petroleum engineering, structural geology, geochemistry, geophysics, marine geology, and more recently, ecology. The field has been enriched by the contributions of distinguished researchers from all these fields. At present, hydrogeology is in transition from a state of discovering new resources and exploiting them efficiently for maximum benefit, to one of judicious management of finite, interconnected resources that are vital for the sustenance of humans and other living things. The future of hydrogeology is likely to be dictated by the subtle balance with which the hydrological, erosional, and nutritional cycles function, and the decision of a technological society to either adapt to the constraints imposed by the balance, or to continue to exploit hydrogeological systems for maximum benefit. Although there is now a trend towards ecological and environmental awareness, human attitudes could change should large parts of the populated world be subjected to the stresses of droughts that last for many decades. Cet article est une rétrospective de l'évolution de l'hydrogéologie en Amérique du Nord sur les deux derniers siècles, et une brève évaluation de son futur. L'histoire de l'hydrogéologie est marquée par le développement de plusieurs techniques de terrain telles, l'hydrologie des eaux souterraines, la mécanique des sols, les sciences du sol, la géologie économique, l' ingénierie pétrolière, la géologie structurale, la géochimie, la géophysique, la géologie marine et plus récemment l'écologie. La science a été enrichie par la contribution de plusieurs chercheurs distingués, provenant de toutes ces branches. A présent, l

    The Advanced Communications Technology Satellite (ACTS) to be launched in 1993 introduces several new technologies including a multibeam antenna (MBA) operating at Ka-band. The satellite is introduced briefly, and then the MBA, consisting of electrically similar 30 GHz received and 20 GHz transmit offset Cassegrain systems utilizing orthogonal linear polarizations, is described. Dual polarization is achieved by using one feed assembly for each polarization in conjunction with nested front and back subreflectors, the gridded front subreflector acting as a window for one polarization and a reflector for the other. The antennas produce spot beams with approximately 0.3 deg beamwidth and gains of approximately 50 dbi. High surface accuracy and high edge taper produce low sidelobe levels and high cross-polarization isolation. A brief description is given of several Ka-band components fabricated for ACTS. These include multiflare antenna feedhorns, beam-forming networks utilizing latching ferrite waveguide switches, a 30 GHz high mobility electron transmitter (HEMT) low-noise amplifier and a 20 GHz TWT power amplifier.

  11. Application of Wall-modeled LES to Turbulent Separated Flows

    NASA Astrophysics Data System (ADS)

    Iyer, Prahladh S.; Park, George I.; Malik, Mujeeb R.

    2016-11-01

    Resolved Large-Eddy Simulations (LES) and Direct Numerical Simulations (DNS) are unaffordable for very high Reynolds number (Re) wall-bounded flows. While the Reynolds Averaged Navier-Stokes (RANS) based methods predict high Re attached flows accurately with little cost, their fidelity is degraded significantly in flows involving separation. A popular compromise between cost and accuracy is to use a Wall-modeled LES (WMLES) approach. In WMLES, the outer portion of the boundary layer is resolved with LES while the inner portion is modeled. In order to assess the performance of the widely used wall-stress models in separated flows, we perform WMLES simulations using an unstructured, compressible finite volume LES solver. The equilibrium and non-equilibrium wall models that require the solution of the simplified/full RANS on a separate near-wall domain are employed. Two configurations are studied: the shock-induced separation in a transonic flow over an axisymmetric bump placed on a cylinder, and a low-Mach flow past a NACA 4412 airfoil at a near-stall condition. Detailed comparisons will be made with available experimental data to comment on the applicability of WMLES in predicting complex turbulent flows involving separation.

  13. DNS and LES of a Shear-Free Mixing Layer

    NASA Technical Reports Server (NTRS)

    Knaepen, B.; Debliquy, O.; Carati, D.

    2003-01-01

    The purpose of this work is twofold. First, given the computational resources available today, it is possible to reach, using DNS, higher Reynolds numbers than in Briggs et al.. In the present study, the microscale Reynolds numbers reached in the low- and high-energy homogeneous regions are, respectively, 32 and 69. The results reported earlier can thus be complemented and their robustness in the presence of increased turbulence studied. The second aim of this work is to perform a detailed and documented LES of the shear-free mixing layer. In that respect, the creation of a DNS database at higher Reynolds number is necessary in order to make meaningful LES assessments. From the point of view of LES, the shear-free mixing-layer is interesting since it allows one to test how traditional LES models perform in the presence of an inhomogeneity without having to deal with difficult numerical issues. Indeed, as argued in Briggs et al., it is possible to use a spectral code to study the shear-free mixing layer and one can thus focus on the accuracy of the modelling while avoiding contamination of the results by commutation errors etc. This paper is organized as follows. First we detail the initialization procedure used in the simulation. Since the flow is not statistically stationary, this initialization procedure has a fairly strong influence on the evolution. Although we will focus here on the shear-free mixing layer, the method proposed in the present work can easily be used for other flows with one inhomogeneous direction. The next section of the article is devoted to the description of the DNS. All the relevant parameters are listed and comparison with the Veeravalli & Warhaft experiment is performed. The section on the LES of the shear-free mixing layer follows. A detailed comparison between the filtered DNS data and the LES predictions is presented. It is shown that simple eddy viscosity models perform very well for the present test case, most probably because the

  14. Stochasticity of convection in Giga-LES data

    NASA Astrophysics Data System (ADS)

    De La Chevrotière, Michèle; Khouider, Boualem; Majda, Andrew J.

    2016-09-01

    The poor representation of tropical convection in general circulation models (GCMs) is believed to be responsible for much of the uncertainty in the predictions of weather and climate in the tropics. The stochastic multicloud model (SMCM) was recently developed by Khouider et al. (Commun Math Sci 8(1):187-216, 2010) to represent the missing variability in GCMs due to unresolved features of organized tropical convection. The SMCM is based on three cloud types (congestus, deep and stratiform), and transitions between these cloud types are formalized in terms of probability rules that are functions of the large-scale environment convective state and a set of seven arbitrary cloud timescale parameters. Here, a statistical inference method based on the Bayesian paradigm is applied to estimate these key cloud timescales from the Giga-LES dataset, a 24-h large-eddy simulation (LES) of deep tropical convection (Khairoutdinov et al. in J Adv Model Earth Syst 1(12), 2009) over a domain comparable to a GCM gridbox. A sequential learning strategy is used where the Giga-LES domain is partitioned into a few subdomains, and atmospheric time series obtained on each subdomain are used to train the Bayesian procedure incrementally. Convergence of the marginal posterior densities for all seven parameters is demonstrated for two different grid partitions, and sensitivity tests to other model parameters are also presented. A single column model simulation using the SMCM parameterization with the Giga-LES inferred parameters reproduces many important statistical features of the Giga-LES run, without any further tuning. In particular it exhibits intermittent dynamical behavior in both the stochastic cloud fractions and the large scale dynamics, with periods of dry phases followed by a coherent sequence of congestus, deep, and stratiform convection, varying on timescales of a few hours consistent with the Giga-LES time series. The chaotic variations of the cloud area fractions were

    NASA Astrophysics Data System (ADS)

    Biskri, Djallel Eddine

    L'aeroservoelasticite est un domaine ou interagissent la structure flexible d'un avion, l'aerodynamique et la commande de vol. De son cote, la commande du vol considere l'avion comme une structure rigide et etudie l'influence du systeme de commande sur la dynamique de vol. Dans cette these, nous avons code trois nouvelles methodes d'approximation de forces aerodynamiques: Moindres carres corriges, Etat minimal corrige et Etats combines. Dans les deux premieres methodes, les erreurs d'approximation entre les forces aerodynamiques approximees par les methodes classiques et celles obtenues par les nouvelles methodes ont les memes formes analytiques que celles des forces aerodynamiques calculees par LS ou MS. Quant a la troisieme methode, celle-ci combine les formulations des forces approximees avec les methodes standards LS et MS. Les vitesses et frequences de battement et les temps d'executions calcules par les nouvelles methodes versus ceux calcules par les methodes classiques ont ete analyses.

  17. Formation des etoiles massives dans les galaxies spirales

    NASA Astrophysics Data System (ADS)

    Lelievre, Mario

    Le but de cette thèse est de décrire la formation des étoiles massives dans les galaxies spirales appartenant à divers types morphologiques. L'imagerie Hα profonde combinée à une robuste méthode d'identification des régions HII ont permis de détecter et de mesurer les propriétés (position, taille, luminosité, taux de formation d'étoiles) de plusieurs régions HII situées dans le disque interne (R < R25) de dix galaxies mais aussi à leur périphérie (R ≥ R 25). De façon générale, la répartition des régions HII ne montre aucune évidence de structure morphologique à R < R25 (bras spiraux, anneau, barre) à moins de limiter l'analyse aux régions HII les plus grosses ou les plus lumineuses. La répartition des régions HII, de même que leur taille et leur luminosité, sont toutefois sujettes à de forts effets de sélection qui dépendent de la distance des galaxies et qu'il faut corriger en ramenant l'échantillon à une résolution spatiale commune. Les fonctions de luminosité montrent que les régions HII les plus brillantes ont tendance à se former dans la portion interne du disque. De plus, l'analyse des pentes révèle une forte corrélation linéaire par rapport au type morphologique. Aucun pic n'est observé dans les fonctions de luminosité à log L-37 qui révèlerait la transition entre les régions HII bornées par l'ionisation et par la densité. Une relation cubique est obtenue entre la taille et la luminosité des régions HII, cette relation variant toutefois de façon significative entre le disque interne et la périphérie d'une même galaxie. La densité et la dynamique du gaz et des étoiles pourraient influencer de façon significative la stabilité des nuages moléculaires face à l'effondrement gravitationnel. D'une part, l'étendue du disque de régions HII pour cinq galaxies de l'échantillon coïncide avec celle de l'hydrogène atomique. D'autre part, en analysant la stabilité des disques galactiques, on conclue

    2014-01-01

    Résumé Question Compte tenu du taux à la hausse de la coqueluche chez les enfants, plusieurs familles m’ont demandé quels moyens prendre pour protéger leurs tout-petits de cette infection. Quelles devraient être mes recommandations à ces familles? Réponse La coqueluche est une maladie évitable qui est endémique dans le monde entier. Chez les adultes, la coqueluche cause une maladie bénigne semblable à un rhume, suivie d’une toux persistante. Chez les nourrissons, elle peut causer de l’apnée, des convulsions, une encéphalopathie, une bronchopneumonie et la mort. Les décès dus à la coqueluche se produisent dans 86 % des cas chez des nourrissons de moins de 4 mois. La stratégie du cocooning, c’est-à-dire la vaccination des adultes en étroit contact avec des nourrissons, est recommandée par de nombreuses agences mondiales et nationales, mais elle ne prévient probablement que 20 % des cas de coqueluche chez les nourrissons. La vaccination durant la grossesse est plus efficace, mais elle n’est pas encore approuvée au Canada. Il n’a pas été démontré que la vaccination à la naissance soit uniformément efficace et elle n’est donc pas recommandée à l’heure actuelle.

    Résumé Objectif Discuter du traitement pharmacologique de la dépression chez les personnes âgées, y compris le choix des antidépresseurs, le titrage de la dose, la surveillance de la réponse et des effets secondaires et le traitement des cas réfractaires. Sources des données Les lignes directrices de 2006 de la Canadian Coalition for Seniors’ Mental Health sur l’évaluation et le traitement de la dépression ont servi comme source principale. Pour recenser les articles publiés après les lignes directrices, on a procédé à une recherche documentaire dans MEDLINE de 2007 à 2012 à l’aide des expressions en anglais depression, treatment, drug therapy et elderly. Message principal Le but du traitement devrait être la rémission des symptômes. L’amélioration des symptômes peut être surveillée en fonction des objectifs du patient qu’on a identifiés ou en se servant d’outils cliniques comme le Patient Health Questionnaire–9. On devrait envisager le traitement en 3 étapes: l’étape du traitement aigu pour obtenir la rémission des symptômes, une étape de continuation pour prévenir la récurrence d’un même épisode de la maladie (rechute) et une étape de maintien (prophylaxie) pour prévenir de futurs épisodes (récurrence). Le dosage initial devrait être la moitié de la dose de départ habituelle chez l’adulte et il devrait être titré régulièrement jusqu’à ce que le patient réponde, jusqu’à ce que la dose maximale soit atteinte ou encore que les effets secondaires en limitent l’augmentation. Parmi les effets secondaires fréquents, on peut mentionner les chutes, la nausée, les étourdissements, les céphalées et, moins communément, l’hyponatrémie et des changements dans l’intervalle QT. Des stratégies pour changer ou augmenter les antidépresseurs sont présentées. Les patients plus âgés devraient être traités pendant au moins un an à compter de l’observation d’une amélioration clinique et

  1. Les astronomes européens auscultent les cieux avec le plus grand télescope du monde

    NASA Astrophysics Data System (ADS)

    Malbet, F.

    2008-09-01

    À l'heure des projets de télescopes extrêmement grands, l'Europe a déjà une longueur d'avance. Le télescope européen (VLT), en mode interférométrique avec l'instrument AMBER devient le plus grand télescope jamais utilisé dans le domaine optique aussi bien en surface de miroir (plus de 150 m2) qúen finesse de résolution qui atteint celle d'un télescope de 130 m de diamètre. Le journal professionnel Astronomy & Astrophysics a publié en 2007 un numéro spécial qui rapporte les premiers résultats obtenus avec l'instrument AMBER (Astronomical MultiBEam Recombiner) par le très grand télescope européen. Ces articles couvrent pratiquement tous les stades de l'évolution stellaire depuis la formation des étoiles et des planètes jusqu'a l'observation de l'explosion de type nova dans un système stellaire évolué. Ces résultats inédits ont été obtenus en utilisant simultanément 3 des 4 télescopes du VLT basés à l'Observatoire européen austral du mont Paranal au Chili. L'instrument AMBER équipant le VLTI (mode interférométrique du VLT) permet dâatteindre une résolution angulaire inégalée de l'ordre du millième de seconde d'angle autorisant l'observation des astres dans différentes longueurs d'onde, dans l'infrarouge proche. Les astronomes obtiennent donc des observations avec une finesse 13 fois plus importante que celle d'un télescope seul. Il devient alors possible de sonder les régions de formation de planètes, d'observer les vents des étoiles en rotation très rapide, d'étudier les différents types de matières éjectées par une étoile massive, de séparer les deux composantes d'une étoile double serrée et de voir en direct l'évolution d'une nova quelques jours seulement après son explosion.

  2. Les cyclones tropicaux et le changement climatique

    André, Jean-Claude; Royer, Jean-François; Chauvin, Fabrice

    2008-09-01

    Results from observations and modelling studies, a number of which having been used to support the conclusions of the IPCC fourth assessment report, are presented. For the past and present-day (since 1970) periods, the increase of strong cyclonic activity over the North Atlantic Ocean appears to be in good correlation with increasing temperature of the ocean surface. For regions where observational data are of lesser quality, the increasing trend is less clear. In fact, assessing long-term changes is made difficult due to both the multi-decennial natural variability and the lesser coverage of observations before satellites were made available. Indirect observational data, such as those derived from quantitative estimations of damage caused by tropical cyclones, suffer from many artefacts and do not allow the resolving of the issue either. For the future, only numerical three-dimensional climate models can be used. They nevertheless run presently with too-large grid-sizes, so that their results are still not converging. Various simulations lead indeed to different results, and it is very often difficult to find the physical reasons for these differences. One concludes by indicating some ways through which numerical simulations could be improved, leading to a decrease of uncertainties affecting the prediction of cyclonic activity over the next decades.

    Introduction Les maladies chroniques non transmissibles (MCNT) constituent un problème de santé publique. La transition épidémiologique coexiste avec les maladies infectieuses. En Afrique subsaharienne, leur ampleur est peu connue et l'OMS recommande aux pays à faible et moyen revenu de réaliser des enquêtes STEPS portant sur les comportements, des mesures physiques et biochimiques. L'absence de données au niveau national justifie cette étude auprès d'un groupe spécifique. L'objectif de l’étude était de déterminer la prévalence des MCNT et de leurs facteurs de risque chez les militaires Sénégalais. Méthodes Une enquête transversale a été réalisée incluant les militaires âgés de 25 à 60 ans. La participation était volontaire et l'accord des autorités hiérarchiques a préalablement été obtenu. Un sondage stratifié à deux niveaux a été utilisé permettant d'avoir un échantillon ajusté de 1513 individus. Les données ont été saisies avec le logiciel EPI Info 6 et analysées à l'aide de R. Un score de risque a été déterminé sur la base de cinq facteurs. Résultats Les résultats préliminaires concernent 1125 personnes. L’âge moyen était de 39,7 ±9,1 ans et le sex-ratio de 28,6. La prévalence du tabagisme actif était de 17,3% et ne variait pas significativement entre les différentes catégories d’âge. L’âge moyen auquel ils ont commencé à fumer était de 20,8 ±4,05 ans. La consommation médiane de fruits et légumes était de l'ordre de 4 par jour et seulement 5,7% des enquêtés prenaient au moins 5 portions par jour. Environs 72% des enquêtés avaient une activité physique intense ou modérée. Les prévalences de la surcharge pondérale, de l'HTA et du diabète étaient de 30,5%, 28,4% et 3,0% respectivement alors que la maladie rénale chronique était retrouvée chez un seul cas. Le calcul du score de risque cardiovasculaire a montré que 39,1% des militaires étaient à risque élevé (≥3 facteurs

  5. LES simulation of cloud-aerosols-chemistry interactions in Western Africa

    2014-12-01

    Low clouds have a major impact on the radiative balance of the earth, in particular in tropical areas. The Southern West Africa (SWA) area encounters during boreal summer frequent formations of stratus and/or cumulus clouds over a large extent. These cloud bands, still badly represented in climatic models, can lead to large errors in the estimation of the cloud radiative forcing. Moreover, these cloud bands can evolve or not in cumulus congestus clouds leading to precipitations. The SWA area is characterized by a large diversity of natural and anthropic emissions of gaseous chemical species and aerosol particles. These emissions have a potential large impact on the number concentration and chemical composition of aerosol particles over the SWA zone. This impact is direct through emissions of primary particles, and indirect through the formation of secondary particles from gaseous precursors. A part of these particles will act as cloud condensation nuclei, thus, influencing the cloud microphysics characteristics. In order to improve our understanding of these complex processes, an airborne campaign is planed in summer 2015 over SWA zone in the framework of the European project DACCIWA (Dynamics-aerosol-chemistry-cloud interactions in West Africa). To prepare the campaign and begin to investigate the cloud-chemistry-aerosols interactions, a LES simulation on a case study designed from an AMMA (African Monsoon Multidisciplinary Analyses) case has been performed with the 3D online-chemistry Meso-NH model. The LES simulation captures the chemical segregation due to thermals in the rising convective boundary layer. Comparing simulation with or without cloud chemistry highlights the effect of aqueous phase chemistry on gaseous precursors of aerosol particles.

  9. Is there a future for electricity futures?

    SciTech Connect

    Hettrick, J.R.; Chittenden, W.T.

    1998-12-31

    The market for electricity based commodity trading, including futures and options, is in its infancy in the United States. Formal trading of electricity futures started on the New York Mercantile Exchange (NYMEX) on March 29, 1996 with Options trading following on April 26, 1996. NYMEX started two new contracts, one based at the California-Oregon border (COB) and one based at the Palo Verde switchyard (Palo Verde). NYMEX is the commodity futures exchange in the United States that specializes in energy contracts, historically launching futures contracts in energy sectors immediately after the deregulation of the market and after the formation of a competitive cash or spot market. In the case of electricity, NYMEX established the new electricity futures contracts prior to the deregulation of the market and in the middle of the formation of a working spot market. Several questions remain including if there is enough interest in the market, who will be the participants, how will the physical properties of electricity mold the terms for futures contracts, and how will deregulation affect the outcome?

    1962-05-22

    A high-current, fast-acting switch is designed for utilization as a crowbar switch in a high-current circuit such as used to generate the magnetic confinement field of a plasma-confining and heat device, e.g., Pyrotron. The device particularly comprises a cylindrical housing containing two stationary, cylindrical contacts between which a movable contact is bridged to close the switch. The movable contact is actuated by a differential-pressure, airdriven piston assembly also within the housing. To absorb the acceleration (and the shock imparted to the device by the rapidly driven, movable contact), an adjustable air buffer assembly is provided, integrally connected to the movable contact and piston assembly. Various safety locks and circuit-synchronizing means are also provided to permit proper cooperation of the invention and the high-current circuit in which it is installed. (AEC)

    Preliminary results are presented for three propagation measurement campaigns involving a mobile receiving laboratory and 20 GHz transmissions from the Advanced Communications Technology Satellite (ACTS). Four 1994 campaigns were executed during weekly periods in and around Austin, Texas in February and May, in Central Maryland during March, and in Fairbanks, Alaska and environs in June. Measurements tested the following effects at 20 GHz: (1) attenuation due to roadside trees with and without foliage, (2) multipath effects for scenarios in which line-of-sight paths were unshadowed, (3) fades due to terrain and roadside obstacles, (4) fades due to structures in urban environs, (5) single tree attenuation, and (6) effects of fading at low elevation angles (8 deg in Fairbanks, Alaska) and high elevation angles (55 deg in Austin, Texas). Results presented here cover sampled measurements in Austin, Texas for foliage and non-foliage cases and in Central Maryland for non-foliage runs.

  5. Adaptive LES Methodology for Turbulent Flow Simulations

    Oleg V. Vasilyev

    2008-06-12

    Although turbulent flows are common in the world around us, a solution to the fundamental equations that govern turbulence still eludes the scientific community. Turbulence has often been called one of the last unsolved problem in classical physics, yet it is clear that the need to accurately predict the effect of turbulent flows impacts virtually every field of science and engineering. As an example, a critical step in making modern computational tools useful in designing aircraft is to be able to accurately predict the lift, drag, and other aerodynamic characteristics in numerical simulations in a reasonable amount of time. Simulations that take months to years to complete are much less useful to the design cycle. Much work has been done toward this goal (Lee-Rausch et al. 2003, Jameson 2003) and as cost effective accurate tools for simulating turbulent flows evolve, we will all benefit from new scientific and engineering breakthroughs. The problem of simulating high Reynolds number (Re) turbulent flows of engineering and scientific interest would have been solved with the advent of Direct Numerical Simulation (DNS) techniques if unlimited computing power, memory, and time could be applied to each particular problem. Yet, given the current and near future computational resources that exist and a reasonable limit on the amount of time an engineer or scientist can wait for a result, the DNS technique will not be useful for more than 'unit' problems for the foreseeable future (Moin & Kim 1997, Jimenez & Moin 1991). The high computational cost for the DNS of three dimensional turbulent flows results from the fact that they have eddies of significant energy in a range of scales from the characteristic length scale of the flow all the way down to the Kolmogorov length scale. The actual cost of doing a three dimensional DNS scales as Re{sup 9/4} due to the large disparity in scales that need to be fully resolved. State-of-the-art DNS calculations of isotropic turbulence

    2001-12-01

    Ce travail est une étude du champ magnétique duns l'environnement circumstellaire des étoiles jeunes. Il a pour origine la certitude qu'avait l'auteur qu'il se devait d'être possible de détecter la présence d'un champ magnétique, et de possiblement le caractériser, par le biais d'observations de profils spectraux d'espèces moléculaires ioniques. Il en découle donc qu'un des buts principaux était de prouver que cela est effectivement possible. La thèse comporte alors des éléments théoriques et expérimentaux qui sont à la fois complémentaires et intimement liés. L'aspect théorique est basé sur l'interaction mutuelle que des particules neutres et chargées peuvent avoir l'une sur l'autre daps un plasma faiblement ionisé comme ceux existants daps les nuages moléculaires sites de formation stellaire. Il appert que la présence d'un champ magnétique a un effet direct sur le comportement des ions (via la force de Lorentz) et indirect sur les molécules neutres (via les nombreuses collisions entre les deux types de particules). Une telle interaction est, comme il est maintenant bien connu, présente dans les premières étapes de la formation dune étoile. Il s'agit bien sûr de la diffusion ambipolaire. Nous montrerons qu'il existe cependant un autre type de diffusion, jusqu'ici inconnue, qui se manifeste plus tard au tours de l'évolution des nuages moléculaires. Celle-ci peut avoir un effet dramatique sur l'apparence des profils spectraux (de rotation moléculaire) des espèces ioniques lorsque comparés à ceux qu'exhibent des espèces neutres coexistantes. Mais pour ce faire, il doit y avoir existence de mouvements organisés (des flots ou jets) de matière ou encore la présence de turbulence dans les régions considérées. Une distribution de vélocité du type maxwellienne ne révèlera pas la présence du champ magnétique. Les observations, qui ont pour but de confirmer la théorie, se situent dans le domaine des longueurs d

    Wildland fires are becoming more prevalent and intense worldwide as climate change leads to warmer, drier conditions; and large-eddy simulation (LES) is receiving increasing attention for fire spread predictions as computing power continues to improve (see, e.g.,). We report results from wildfire simulations over general terrain employing implicit LES for solution of the incompressible Navier-Stokes (N.-S.) and thermal energy equations with Boussinesq approximation, altered with Darcy, Forchheimer and Brinkman extensions, to represent forested regions as porous media with varying (in both space and time) porosity and permeability. We focus on subgrid-scale (SGS) behaviors computed with a synthetic-velocity model, a discrete dynamical system, based on the poor man's N.-S. equations and investigate the ability of this model to produce fire whirls (tornadoes of fire) at the (unresolved) SGS level.

    La tuberculose multifocale est définie par la l'atteinte d'au moins deux sites extra-pulmonaires associée ou non à une atteinte pulmonaire. On se propose d’étudier les différentes caractéristiques cliniques et évolutives de la tuberculose multifocale à travers une étude rétrospective de 10 cas. Parmi 41 cas de tuberculose colligés entre 1999 et 2013. Dix patients avaient une tuberculose multifocale, soit 24% des patients. Il s'agissait de 9 femmes et 1 homme d’âge moyen à 50 ans (30-68 ans). Nos patients étaient tous correctement vaccinés par le BCG. Un bilan à la recherche d'une éventuelle immunodépression fait pour tous les patients était négatif. Il s'agissait d'une tuberculose ganglionnaire dans 7 cas, digestive dans 3 cas, péricardique dans 2 cas, ostéo-articulaire dans 2 cas, cérébrale dans 1 cas, urinaire dans 2 cas, uro-génitale dans 4 cas, surrénalienne dans 1 cas, cutanée dans 1 cas et musculaire dans 1 cas. Tous nos patients ont bénéficié d'un traitement antituberculeux pour une durée moyenne de 10 mois avec bonne évolution. La tuberculose multifocale est une des maladies à diagnostic difficile. Elle peut toucher les immunocompétents mais son pronostic est souvent bon. Un traitement anti-tuberculeux doit être instauré le plus rapidement possible pour éviter les séquelles. PMID:27583077

    A standard file format is proposed to store process and event information, primarily output from parton-level event generators for further use by general-purpose ones. The information content is identical with what was already defined by the Les Houches Accord five years ago, but then in terms of Fortran commonblocks. This information is embedded in a minimal XML-style structure, for clarity and to simplify parsing.

  11. A New Concept for Representing Trees in LES Simulations

    NASA Astrophysics Data System (ADS)

    Bohrer, G.; Walko, R. L.; Avissar, R.

    2006-12-01

    Atmosphere-biosphere interactions have become an important focus in Earth science. Key issues involving this type of interactions, such as dispersal of aerosols, seeds and pollen from forest canopies into the atmospheric boundary layer (ABL), require a good understanding of turbulence in and near plant canopies. With modern computers, it is now feasible to use Large-Eddy Simulations (LES) at quite high resolution. Thus, we upgraded the LES version of the Regional Atmospheric Modeling System (RAMS) so that it can simulate turbulence inside forest canopies (hereafter referred to as the "RAMS Forest LES" RAFLES) while accounting explicitly for some of the tree characteristics. The simulation domain consists of the tree canopy that is constructed using the Virtual Canopy Generator (V-CaGe) based on observed structural properties of the forest. This canopy can be heterogeneous in all three dimensions. It interacts with the flow field by (1) generating obstacles to the flow resulting from the woody component of the canopy, (2) exchanging heat and vapor with the atmosphere, and (3) dragging the flow with the tree leaves. The "shaved" grid-cell technique is used to represent the obstacle field. RAFLES inherits from RAMS all its other characteristics (including its physics, grid-nesting structure, boundary conditions, data assimilation, and parallel computing, among others). Thus, it simulates atmospheric processes at the mesoscale and resolves the full depth of the ABL, which does not need to be parameterized as in other typical LES. RAFLES was evaluated with the high-frequency observations collected at the Duke Forest FACE site and it is used to study the impacts of various heterogeneous canopies on turbulence, seeds and pollen dispersal.

    Introduction longtemps négligé, le paludisme asymptomatique est actuellement reconnu comme potentielle menace et frein au contrôle du paludisme. En RD Congo, la prévalence de cette parasitémie est peu documentée. L'objectif de cette étude était de déterminer la prévalence de la parasitémie asymptomatique aussi bien chez les enfants de moins de 5 ans que ceux âgés de plus de cinq ans aux regards des interventions de masse en cours (MILDS). Méthodes il s'agit d'une étude transversale menée chez les écoliers et chez les enfants de moins de cinq ans dans les ménages de Lubumbashi. Les écoles, les écoliers et les enfants de moins de 5 ans avaient été sélectionnés aléatoirement. Les frottis, gouttes épaisses et les tests rapides avaient été prélevés et lues. Résultats sur 350 écoliers examinés, 43 soit une prévalence de 12,3%, IC 95% (9,14-16,04) avaient une goutte épaisse positive. Dans tous les 43 cas, seul le Plasmodium falciparum a été identifié.314 ménages, soit 90,5% ont déclaré avoir recouru aux antipaludéens pour soigner la fièvre de leurs enfants à domicile. Plus d'1/3 des enfants dans les ménages, soit 39,9% des interviewés avait avoué avoir recouru aux antipyrétiques pour soulager la fièvre de leurs enfants, 19,7% à la quinine et seulement moins de 2% aux ACT à base de Lumefantrine. En considérant l'utilisation des TDR, la prévalence due à la parasitémie asymptomatique est de 3% IC 95% (2,075-4,44), mais quand on considère la microscopie comme le gold standard, cette prévalence est de 1,9%, IC 95% (1,13-3,01). Conclusion le paludisme asymptomatique n'est pas exempt de toute conséquence sur la santé, il est donc important de mener des enquêtes pareilles pour identifier les nouvelles stratégies de contrôle du paludisme.

    Le but de cette étude était d’étudier le profil épidémioclinique et paraclinique de nos patients, d’évaluer leur prise en charge thérapeutique et leur évolution. Nous avons inclus 130 patients pris en charge entre janvier 2007 et novembre 2009. Nous avons relevé de manière rétrospective les données épidémiologiques, les données cliniques, la prise en charge thérapeutique médico-chirurgicale et l’évolution. Notre série retrouve une prédominance masculine avec un âge moyen de 31 ans. L’origine dentaire est l’étiologie la plus fréquente. La tomodensitométrie avec injection de produit de contraste est l’examen clé du bilan initial. L’antibiothérapie et la chirurgie ont permis une bonne évolution dans 74% des cas. Le taux de mortalité est de 0%. Les cellulites cervico-faciales sont des pathologies potentiellement graves touchant souvent des adultes jeunes dont la mortalité hospitalière doit être réduite à la condition d’un diagnostic précoce et une prise en charge médico-chirurgicale immédiate.

    In order to estimate the ventilation of vehicle pollution within street canyons, a wind tunnel experiment and a large eddy simulation (LES) was performed. A model of an idealised urban area with apartment houses arranged to courtyards was designed according to common Central European cities. In the wind tunnel, we assembled a set-up for simultaneous measurement of vertical velocity and tracer gas concentration. Due to the vehicle traffic emissions modelling, a new line source of tracer gas was designed and built into the model. As a computational model, the LES model solving the incompressible Navier-Stokes equations was used. In this paper, we focused on the street canyon with the line source situated perpendicular to an approach flow. Vertical and longitudinal velocity components of the flow with the pollutant concentration were obtained from two horizontal grids placed in different heights above the street canyon. Vertical advective and turbulent pollution fluxes were computed from the measured data as ventilation characteristics. Wind tunnel and LES data were qualitatively compared. A domination of advective pollution transport within the street canyon was determined. However, the turbulent transport with an opposite direction to the advective played a significant role within and above the street canyon.

    La présence de fluctuations irréductibles de champ dans le vide est une prédiction importante de la théorie quantique. Ces fluctuations ont de nombreux effets bien connus, dont l'archétype est la force de Casimir apparaîssant entre deux miroirs placés dans le vide par suite de la pression de radiation du vide. Elle a été récemment mesurée avec une précision de l'ordre du %. De nombreux travaux sont consacrés à l'évaluation théorique de cette force en visant une précision du même ordre. Ici nous étudions la force de Casimir dans la configuration de deux miroirs métalliques plans parallèles à température nulle. En supposant les miroirs décrits par un modèle plasma nous interprétons la force de Casimir comme le résultat de l'interaction entre les plasmons de surface des deux miroirs.

    Résumé Question Une otite moyenne aiguë chez un patient de 2 ans qui fréquente ma clinique a dégénéré en mastoïdite avec forte fièvre et les résultats de culture se sont révélés positifs pour le Fusobacterium. Que dois-je faire ensuite? Réponse Le Fusobacterium est un genre de bactéries anaérobies. Quoique les infections à Fusobacterium soient rares, elles peuvent devenir graves si elles ne sont pas traitées rapidement. Le traitement approprié est une antibiothérapie combinée associant une β-lactamine (pénicilline, céphalosporine) et un agent contre les microbes anaérobies (métronidazole, clindamycine). Il faut parfois une intervention chirurgicale pour la mastoïdite, comme le drainage d’abcès ou l’insertion d’un tube de ventilation. Le traitement tardif d’une infection causée par le Fusobacterium peut entraîner de sérieuses complications, dont le syndrome de Lemierre. Il faudrait une surveillance étroite de l’enfant en milieu hospitalier. PMID:27737993

  20. LES/FMDF of High Speed Spray Combustion

    NASA Astrophysics Data System (ADS)

    Irannejad, Abolfazl; Jaberi, Farhad

    2013-11-01

    High speed evaporating and combusting sprays are computed with the hybrid two-phase large eddy simulation (LES)/filtered mass density function (FMDF) methodology. In this methodology, the resolved fluid velocity is obtained by solving the filtered form of the compressible Navier-Stokes equations with high-order finite difference schemes. The scalar (temperature and species mass fractions) field is obtained by solving the FMDF transport equation with a Lagrangian stochastic method. The spray is simulated with the Lagrangian droplets together with stochastic breakup and finite rate heat and mass transfer models. The liquid volume fraction is included in the LES/FMDF for denser spray regions. Simulations of high speed evaporating sprays with and without combustion for a range of gas and spray conditions indicate that the two-phase LES/FMDF results are consistent and compare well with the experimental results for global spray variables such as the spray penetration and flame lift-off lengths. The gas velocity and turbulence generated by the spray are found to be very significant in all simulated cases. A broad spectrum of droplet sizes is also found to be generated by the complex and coupled effects of the gas flow turbulence, droplet breakup, evaporation and combustion.

  1. DNS and LES of Separated Flows at Moderate Reynolds Numbers

    Flows in rotating machinery, for unmanned and micro aerial vehicles, wind turbines, and propellers consist of different flow regimes. First, a laminar boundary layer is followed by a laminar separation bubble with a shear layer on top of it that experiences transition to turbulence. Subsequently, the separated turbulent flow reattaches and evolves downstream from a nonequilibrium turbulent boundary layer to an equilibrium one. Typical RANS and LES turbulence modeling methods experience difficulties when simulating such flows because they were developed for fully developed turbulent flows. This currently leaves DNS as the only reliable but computationally expensive alternative. Our work assesses the capability of LES to reduce the resolution requirements for such flows. Flow over a flat plate with suitable velocity boundary conditions away from the plate to produce a separation bubble is considered. Benchmark DNS data for this configuration was generated with the resolution of 50 ×106 mesh points; also used was a different DNS database with 15 ×106 points reported by Spalart and Strelets in JFM 403 (2000). Employing two codes, one using structured and another unstructured mesh, we concluded that accurate LES are possible using O(1%) of the DNS resolution.

    2008-12-01

    Kant's essay Idea for a universal history with a cosmopolitan purpose differs in deep ways from standard Enlightenment views of human history. Although he agrees with many contemporaries that unsocial sociability can drive human progress, he argues that we know too little about the trends of history to offer either metaphysical defence or empirical vindication of the perfectibility of man or the inevitability of progress. However, as freely acting beings we can contribute to a better future, so have grounds for committing ourselves to human progress even if we cannot guarantee or know that it will continue indefinitely. As Kant sees, it, human progress is better seen as a practical assumption--an Idea of Reason--than as a theoretical claim.

  5. Fast-Acting Valve

    NASA Technical Reports Server (NTRS)

    Wojciechowski, Bogdan V. (Inventor); Pegg, Robert J. (Inventor)

    2003-01-01

    A fast-acting valve includes an annular valve seat that defines an annular valve orifice between the edges of the annular valve seat, an annular valve plug sized to cover the valve orifice when the valve is closed, and a valve-plug holder for moving the annular valve plug on and off the annular valve seat. The use of an annular orifice reduces the characteristic distance between the edges of the valve seat. Rather than this distance being equal to the diameter of the orifice, as it is for a conventional circular orifice, the characteristic distance equals the distance between the inner and outer radii (for a circular annulus). The reduced characteristic distance greatly reduces the gap required between the annular valve plug and the annular valve seat for the valve to be fully open, thereby greatly reducing the required stroke and corresponding speed and acceleration of the annular valve plug. The use of a valve-plug holder that is under independent control to move the annular valve plug between its open and closed positions is important for achieving controllable fast operation of the valve.

    A double acting bit holder that permits bits held in it to be resharpened during cutting action to increase energy efficiency by reducing the amount of small chips produced. The holder consist of: a stationary base portion capable of being fixed to a cutter head of an excavation machine and having an integral extension therefrom with a bore hole therethrough to accommodate a pin shaft; a movable portion coextensive with the base having a pin shaft integrally extending therefrom that is insertable in the bore hole of the base member to permit the moveable portion to rotate about the axis of the pin shaft; a recess in the movable portion of the holder to accommodate a shank of a bit; and a biased spring disposed in adjoining openings in the base and moveable portions of the holder to permit the moveable portion to pivot around the pin shaft during cutting action of a bit fixed in a turret to allow front, mid and back positions of the bit during cutting to lessen creation of small chip amounts and resharpen the bit during excavation use.

  7. Long-acting progestogens.

    PubMed

    Affandi, Biran

    2002-04-01

    Steroids can be administered in at least five different ways: injectables; hormone-releasing intra-uterine devices (IUDs); implants; vaginal rings; and pills. Progestogens which are synthetic steroids, are used as the main bioactive substances. Different progestogens are effective for different periods of time. Progestins in daily oral pills are effective for 24 hours. The effectiveness of a progestogen can be prolonged by incorporating it in a sustained-release system that gradually releases the hormone; therefore they can be effective up to 5 years or more. Two progestogen-only injectables are widely available in the family planning programmes, (DMPA and NET-EN) and two combined injectables, Cyclofem (DMPA + EC), and Mesigyna (NET-EN + EV). The ring is placed by the woman in her vagina, where it gradually releases hormone. Implantable contraceptives are placed just under the skin on the inside of the woman's arm. Implant capsules release the progestogen at a slow, steady rate. There are three implantables available in the market: Implanon; Norplant; and Jadelle. They are effective for 1-5 years, but then must be replaced. Natural and synthetic progestogens were first added to IUDs in the early 1970s. The main problem of long-acting progestogens is the disruption of the menstrual cycle.

    1993-01-01

    This report is concerned with agents that act to gain information. In previous work, we developed agent models combining qualitative modeling with real-time control. That work, however, focused primarily on actions that affect physical states of the environment. The current study extends that work by explicitly considering problems of active information-gathering and by exploring specialized aspects of information-gathering in computational perception, learning, and language. In our theoretical investigations, we analyzed agents into their perceptual and action components and identified these with elements of a state-machine model of control. The mathematical properties of each was developed in isolation and interactions were then studied. We considered the complexity dimension and the uncertainty dimension and related these to intelligent-agent design issues. We also explored active information gathering in visual processing. Working within the active vision paradigm, we developed a concept of 'minimal meaningful measurements' suitable for demand-driven vision. We then developed and tested an architecture for ongoing recognition and interpretation of visual information. In the area of information gathering through learning, we explored techniques for coping with combinatorial complexity. We also explored information gathering through explicit linguistic action by considering the nature of conversational rules, coordination, and situated communication behavior.

C'est une étude rétrospective de 33 cas de sarcome des tissus mous, colligés entre janvier 2008 et décembre 2010. Les critères d’éligibilité étaient un âge supérieur à 16 ans, une épreuve histologique d'un sarcome des tissus mous à l'exclusion des tumeurs stromales gastro-intestinales (GIST). Les items recueillis étaient: épidémiologiques, cliniques, histologiques, Radiologiques, et thérapeutiques. Des analyses univariées puis multivariées ont été réalisées à la recherche de facteurs influençant la survie à 2 ans. Il s'agit de 33 cas, 17 Hommes et 16 Femmes, l’âge moyen était de 43,21 ans (Extrêmes= 18-76 ans). La tumeur était localisée aux extrémités dans 24 cas (72,72%). Le type histologique prédominant était le Liposarcome dans 9 cas (27,27%). Le stade tumoral était localisé dans 25 cas (75,8%), métastatique dans 8 cas (24,2%). Vingt-cinq tumeurs ont été traitées chirurgicalement dont 21 cas (84%) de chirurgie conservatrice et 4 cas (16%) de chirurgie radicale. La radiothérapie a été réalisée chez 10 patients (30,3%). La chimiothérapie a été faite chez 20 patients. En analyse univariée les facteurs pronostiques étaient l’âge (p=0,03) et le stade tumoral (p=0,09). L’âge et le stade tumoral sont des facteurs pronostiques influençant la survie des sarcomes des tissus mous. PMID:27022434

    Rebiere, Jeremy

    De nos jours, avec la raréfaction des ressources fossiles, le développement de procédés entrant dans le cadre de la chimie verte s'accentue. De plus, ces procédés utilisent comme ressources, des matériaux d'origine végétale, abondants et biodégradables. Au cours de ces 20 dernières années, la littérature utilisant les liquides ioniques (LI) connait une importante croissance. Ces solvants sont de plus en plus employés dans des réactions chimiques classiques. Cependant le coût de leur synthèse en fait un solvant réactionnel cher dont l'application en tant que tel dans l'industrie ne peut être raisonnablement envisagée. Ces liquides ioniques permettent la dissolution des matériaux lignocellulosiques (lignine ou cellulose) et possèdent des propriétés physico-chimiques intéressantes. Nous savons également que la dissolution de la cellulose par des procédés d'hydrolyse classique s'effectue dans des conditions dures, dues à la structure cristalline de la cellulose, (fortes concentrations en acide) qui paraissent limitées pour une utilisation à grande échelle. Il est donc nécessaire de rechercher des méthodes moins onéreuses et plus efficaces écologiquement. S'appuyant sur des recherches démontrant que la dissolution de la cellulose dans les LI, diminue la cristallinité de la cellulose, nous allons chercher à démontrer au cours de ces travaux, la possibilité d'utiliser les LI comme moyen de prétraitement pour la dissolution de la cellulose. Nous allons nous attacher à dissoudre la cellulose, et à étudier les proportions pouvant être dissoutes. Puis nous chercherons à récupérer puis à réutiliser ces LI. Enfin nous cherchons à caractériser les modifications apportées à notre cellulose.

  14. English Language Learners in the Elementary and Secondary Education Act

    ERIC Educational Resources Information Center

    Calderon, Brenda

    2015-01-01

    The Elementary and Secondary Education Act has provided services for English Language Learners (ELLs) since 1968. In 2010 nearly 4.6 million students were classified as ELLs and of those nearly 80% were from a Spanish speaking background. To ignore their education is to neglect preparing a large portion of our nation's future workforce. Given…

  15. [Euthanasia and medical act].

    PubMed

    2011-05-01

    Right to life -as the prohibition of intentionally and arbitrarily taking life, even with authorization of the concerned one- is an internationally recognized right. In many countries, debate regarding euthanasia is more centered in its convenience, social acceptability and how it is regulated, than in its substantial legitimacy. Some argue that euthanasia should be included as part of clinical practice of health professionals, grounded on individual's autonomy claims-everyone having the liberty to choose how to live and how to die. Against this, others sustain that life has a higher value than autonomy, exercising autonomy without respecting the right to life would become a serious moral and social problem. Likewise, euthanasia supporters some-times claim a 'right to live with dignity', which must be understood as a personal obligation, referred more to the ethical than to the strictly legal sphere. In countries where it is already legalized, euthanasia practice has extended to cases where it is not the patient who requests this but the family or some healthcare professional, or even the legal system-when they think that the patient is living in a condition which is not worthy to live. Generalization of euthanasia possibly will end in affecting those who need more care, such as elder, chronically ill or dying people, damaging severely personal basic rights. Nature, purpose and tradition of medicine rule out the practice of euthanasia, which ought not be considered a medical act or legitimately compulsory for physicians. Today's medicine counts with effective treatments for pain and suffering, such as palliative care, including sedative therapy, which best preserves persons dignity and keeps safe the ethos of the medical profession.

    2016-01-01

    Introduction L'hémogramme est un bilan biologique de routine demandé chez tout patient souffrant d'Hypertension Artérielle (HTA). Cette étude se propose de décrire les résultats d'hémogramme chez les hypertendus et d'identifier les pathologies associées. Méthodes Il s'agit d'une étude rétrospective type descriptif s’étalant du 01 Décembre 2012 au 31 Décembre 2013 au laboratoire du Centre Hospitalo-Universitaire Hôpital Joseph Raseta Befelatanana (CHU-HJRB) d'Antananarivo. Tous les registres des résultats des hypertendus demandant un hémogramme ont été exploités. Résultats Parmi les 151 hypertendus, 91 (60,3%) ont présenté des hémogrammes pathologiques. Parmi ces derniers, 64 (70,4%) ont montré un seul type d'anomalie et 27 (29,6%) des anomalies multiples. Les anémies (33,91%), les hyperleucocytoses (33,04%), les polyglobulies (10,43%) et les leucopénies (9,57%) sont les plus fréquentes. Pour les anomalies multiples, les anémies associées aux hyperleucocytoses sont les plus observées (29,6%). Les anémies microcytaires (41%) et les hyperleucocytoses à polynucléaires neutrophiles sont les plus dominantes (47,4%). Les patients hospitalisés en néphrologie (90%) et en endocrinologie (81,3%) sont les plus concernés (p = 0,008). Les hypertendus moins de 20 ans (100%) et les femmes (61,5%) sont les plus affectés (p > 0,05). Les crises convulsives (100%), les œdèmes des membres inférieurs (100%) et le diabète (70%) sont les signes et pathologies associés les plus rencontrés (p > 0,05). Conclusion L'hémogramme doit être prescrit chez tout patient hypertendu pour connaître les affections sous-jacentes qui seront traitées simultanément avec l'HTA. Ainsi, le patient hypertendu sera pris en charge convenablement et son espérance de vie sera améliorée. PMID:27217875

    Les décisions en matière de réglementation et les documents scientifiques au sujet de la prise en charge du trouble de déficit de l’attention avec hyperactivité (TDAH) soulèvent des questions quant à l’innocuité des médicaments et à l’évaluation convenable à effectuer avant le traitement afin de déterminer la pertinence d’une pharmacothérapie. Ce constat est particulièrement vrai en présence de cardiopathies structurelles ou fonctionnelles. Le présent article contient l’analyse des données disponibles, y compris les publications révisées par des pairs, des données tirées du site Web de la Food and Drug Administration des États-Unis au sujet des réactions indésirables déclarées chez des enfants qui prennent des stimulants, ainsi que des données de Santé Canada sur le même problème. Des lignes directrices consensuelles sur l’évaluation pertinente sont proposées d’après l’apport des membres de la Société canadienne de pédiatrie, de la Société canadienne de cardiologie et de l’Académie canadienne de psychiatrie de l’enfant et de l’adolescent, qui possèdent notamment des compétences et des connaissances précises tant dans le secteur du TDAH que de la cardiologie pédiatrique. Le présent document de principes prône une anamnèse et un examen physique détaillés avant la prescription de stimulants et s’attarde sur le dépistage des facteurs de risque de mort subite, mais il ne contient pas de recommandations systématiques de dépistage électrocardiographique ou de consultations avec un spécialiste en cardiologie, à moins que les antécédents ou que l’examen physique ne le justifient. Le document contient un questionnaire pour repérer les enfants potentiellement vulnérables à une mort subite (quel que soit le type de TDAH ou les médicaments utilisés pour le traiter). Même si les recommandations dépendent des meilleures données probantes disponibles, le comité s’entend pour affirmer que

  20. Coal: Energy for the future

    SciTech Connect

    1995-05-01

    This report was prepared in response to a request by the US Department of energy (DOE). The principal objectives of the study were to assess the current DOE coal program vis-a-vis the provisions of the Energy Policy Act of 1992 (EPACT), and to recommend the emphasis and priorities that DOE should consider in updating its strategic plan for coal. A strategic plan for research, development, demonstration, and commercialization (RDD and C) activities for coal should be based on assumptions regarding the future supply and price of competing energy sources, the demand for products manufactured from these sources, technological opportunities, and the need to control the environmental impact of waste streams. These factors change with time. Accordingly, the committee generated strategic planning scenarios for three time periods: near-term, 1995--2005; mid-term, 2006--2020; and, long-term, 2021--2040. The report is divided into the following chapters: executive summary; introduction and scope of the study; overview of US DOE programs and planning; trends and issues for future coal use; the strategic planning framework; coal preparation, coal liquid mixtures, and coal bed methane recovery; clean fuels and specialty products from coal; electric power generation; technology demonstration and commercialization; advanced research programs; conclusions and recommendations; appendices; and glossary. 174 refs.

    The Advanced Communication Technology Satellite (ACTS) is a key to reaching NASA's goal of developing high-risk, advanced communications technology using multiple frequency bands to support the nation's future communication needs. Using the multiple, dynamic hopping spot beams, and advanced on board switching and processing systems, ACTS will open a new era in communications satellite technology. One of the key technologies to be validated as part of the ACTS program is the multibeam antenna with rapidly reconfigurable hopping and fixed spot beam to serve users equipped with small-aperature terminals within the coverage areas. The proposed antenna technology experiments are designed to evaluate in-orbit ACTS multibeam antenna performance (radiation pattern, gain, cross pol levels, etc.).

    NASA Astrophysics Data System (ADS)

    Faribault, Alexandre

    On peut creer un gaz electronique bidimensionnel en utilisant le potentiel de confinement d'une couche mince d'un semiconducteur dans un substrat fait d'une autre semiconducteur de gap plus eleve. L'ajout d'un champ magnetique perpendiculaire au plan de confinement modifie de facon drastique les proprietes du gaz electronique. Pour des densites et des valeurs du champ magnetique adequatement choisies, on obtient un etat fondamental en onde de densite de charge. Dans un systeme compose de deux de ces gaz bidimensionnels suffisamment rapproches l'un de l'autre, on prevoit theoriquement l'existence d'un etat fondamental compose d'une onde de densite de charge dans chacun des puits et d'une serie de regions lineaires ou l'on a une delocalisation coherente des electrons entre les deux puits. Dans cette these, on etudie le comportement a temperature nulle de cet etat fondamental en rayures coherentes. L'etude numerique des modes collectifs de ces phases laisse croire qu'un deverrouillage des canaux coherents est envisageable dans ce systeme. Afin d'etudier cette possibilite, nous construisons d'abord un modele effectif de canaux quasi-unidimensionnels couples qui permettent de reproduire correctement les excitations collectives a basse energie de la phase en rayures coherentes du double puits quantique. Dans un systeme de coordonnees adequatement choisi, ces excitations peuvent etre decrites par des ondes de pseudospin. Les parametres de ce modele effectif simple peuvent etre extraits des calculs des fonctions de reponse realises dans l'approximation Hartree-Fock dependante du temps (appelee aussi Generalized Random Phase Approximation). On constate l'efficacite de ce modele a decrire la dynamique basse energie du systeme pour une certaine plage de distances inter-puits. En retirant de ce modele les contributions a l'hamiltonien provenant des couplages de type Josephson entre les canaux, on obtient alors un systeme ou les canaux sont deverrouilles. Un traitement en

  16. The development of future thinking: young children's ability to construct event sequences to achieve future goals.

    PubMed

    Prabhakar, Janani; Hudson, Judith A

    2014-11-01

    Previous studies suggest that the ability to think about and act on the future emerges between 3 and 5 years of age. However, it is unclear what underlying processes change during the development of early future-oriented behavior. We report three experiments that tested the emergence of future thinking ability through children's ability to explicitly maintain future goals and construct future scenarios. Our main objectives were to examine the effects of goal structure and the effects of working memory demands on children's ability to construct future scenarios and make choices to satisfy future goals. The results indicate that 4-year-olds were able to successfully accomplish two temporally ordered goals even with high working memory demands and a complex goal structure, whereas 3-year-olds were able to accomplish two goals only when the working memory demands were low and the goal structure did not involve additional demands from inferential reasoning and contingencies between the temporally ordered goals. Results are discussed in terms of the development of future thinking in conjunction with working memory, inferential reasoning ability, and goal maintenance abilities.

    HISTORIQUE : Les antipsychotiques de deuxième génération s’associent souvent à des complications métaboliques. Ces médicaments sont utilisés plus souvent pour le traitement des troubles de santé mentale chez les enfants, ce qui a requis l’élaboration de lignes directrices officielles sur la surveillance de leur innocuité et de leur efficacité. Des lignes directrices ont déjà été élaborées pour surveiller les complications métaboliques et neurologiques. Afin d’aider les praticiens qui effectuent ces interventions de surveillance, une série de recommandations thérapeutiques complémentaires a été élaborée pour les cas où l’on observe des mesures ou des résultats anormaux. OBJECTIF : Créer des recommandations probantes afin de contribuer à la prise en charge des complications métaboliques chez les enfants traités au moyen d’antipsychotiques de deuxième génération. MÉTHODOLOGIE : Les auteurs ont procédé à une analyse systématique des publications sur les complications métaboliques des antipsychotiques de deuxième génération chez les enfants. Les membres du groupe consensuel ont évalué l’information recueillie grâce à l’analyse bibliographique systématique et ont fait appel à un processus de groupe nominal pour parvenir à un consensus à l’égard de recommandations thérapeutiques. Dans la mesure du possible, ils se sont reportés aux lignes directrices existantes sur l’évaluation et le traitement des anomalies métaboliques chez les enfants. RÉSULTATS : Des recommandations probantes sont présentées pour contribuer à la prise en charge des complications métaboliques, y compris la prise de poids, l’augmentation du tour de taille, l’élévation des taux de prolactine, de cholestérol, de triglycérides et de glucose, les épreuves de fonction hépatique anormales et les études thyroïdiennes anormales. CONCLUSION : Il faut recourir à des mesures de surveillance convenables lorsqu’on prescrit

    To make America less dependent on foreign oil, Montana Governor Brain Schweitzer pushes for investment in synfuel technology. He advocates coal as the 'new fuel' for cars and believes synfuels from coal can bridge the gap between the petroleum economy of the past and the hydrogen economy of the future. He is pushing for a 'Future Fuels' project to form a public-private partnership to build 20 coal conversion, synfuel manufacturing plants. This could contribute to making the USA energy self-sufficient, more quickly than the FutureGen project, he believes.

  7. LES of an ignition sequence in a gas turbine engine

    Being able to ignite or reignite a gas turbine engine in a cold and rarefied atmosphere is a critical issue for many manufacturers. From a fundamental point of view, the ignition of the first burner and the flame propagation from one burner to another are phenomena that are usually not studied. The present work is a large eddy simulation (LES) of these phenomena. To simulate a complete ignition sequence in an annular chamber, LES has been applied to the full 360 geometry, including 18 burners. This geometry corresponds to a real gas turbine chamber. Massively parallel computing (700 processors on a Cray XT3 machine) was essential to perform such a large calculation. Results show that liquid fuel injection has a strong influence on the ignition times. Moreover, the rate of flame progress from burner to burner is much higher than the turbulent flame speed due to a major effect of thermal expansion. This flame speed is also strongly modified by the main burner aerodynamics due to the swirled injection. Finally, the variability of the combustor sectors and quadrant ignition times is highlighted.

  8. LES on unstructured deforming meshes: Towards reciprocating IC engines

    Haworth, D. C.; Jansen, K.

    1996-01-01

    A variable explicit/implicit characteristics-based advection scheme that is second-order accurate in space and time has been developed recently for unstructured deforming meshes (O'Rourke & Sahota 1996a). To explore the suitability of this methodology for Large-Eddy Simulation (LES), three subgrid-scale turbulence models have been implemented in the CHAD CFD code (O'Rourke & Sahota 1996b): a constant-coefficient Smagorinsky model, a dynamic Smagorinsky model for flows having one or more directions of statistical homogeneity, and a Lagrangian dynamic Smagorinsky model for flows having no spatial or temporal homogeneity (Meneveau et al. 1996). Computations have been made for three canonical flows, progressing towards the intended application of in-cylinder flow in a reciprocating engine. Grid sizes were selected to be comparable to the coarsest meshes used in earlier spectral LES studies. Quantitative results are reported for decaying homogeneous isotropic turbulence, and for a planar channel flow. Computations are compared to experimental measurements, to Direct-Numerical Simulation (DNS) data, and to Rapid-Distortion Theory (RDT) where appropriate. Generally satisfactory evolution of first and second moments is found on these coarse meshes; deviations are attributed to insufficient mesh resolution. Issues include mesh resolution and computational requirements for a specified level of accuracy, analytic characterization of the filtering implied by the numerical method, wall treatment, and inflow boundary conditions. To resolve these issues, finer-mesh simulations and computations of a simplified axisymmetric reciprocating piston-cylinder assembly are in progress.

  9. High speed turbulent reacting flows: DNS and LES

    NASA Technical Reports Server (NTRS)

    Givi, Peyman

    1990-01-01

    Work on understanding the mechanisms of mixing and reaction in high speed turbulent reacting flows was continued. Efforts, in particular, were concentrated on taking advantage of modern computational methods to simulate high speed turbulent flows. In doing so, two methodologies were used: large eddy simulations (LES) and direct numerical simulations (DNS). In the work related with LES the objective is to study the behavior of the probability density functions (pdfs) of scalar properties within the subgrid in reacting turbulent flows. The data base obtained by DNS for a detailed study of the pdf characteristics within the subgrid was used. Simulations are performed for flows under various initializations to include the effects of compressibility on mixing and chemical reactions. In the work related with DNS, a two-dimensional temporally developing high speed mixing layer under the influence of a second-order non-equilibrium chemical reaction of the type A + B yields products + heat was considered. Simulations were performed with different magnitudes of the convective Mach numbers and with different chemical kinetic parameters for the purpose of examining the isolated effects of the compressibility and the heat released by the chemical reactions on the structure of the layer. A full compressible code was developed and utilized, so that the coupling between mixing and chemical reactions is captured in a realistic manner.

  10. Three-dimensional CLEM-LES of irregular detonation propagation

    Maxwell, Brian; Radulescu, Matei

    2016-11-01

    Recently, thin-channel experiments and 2D simulations have been conducted in order to investigate the effect of turbulent mixing rates on the structure of irregular detonation wave propagation. Furthermore, the dependence of the observed cell pattern, and also the reaction zone thickness, on the mixing of burned products with pockets of unburned gases, was investigated. The current work now includes 3D simulations, which are conducted to provide further validation of, and insight into, the 2D results. All simulations have been conducted using the Compressible Linear Eddy Model for Large Eddy Simulation (CLEM-LES). To date, the 3D results are found to match closely the previous 2D results. The agrreement is partly due to sufficient resolution of the large scale fluid motions, which are observed experimentally to be predominant in only two directions. Furthermore, the CLEM-LES methodology incorporates 3D mixing effects at the subgrid level. Finally, it was found that turbulent fluctuations on the subgrid were found to give rise to statistically lower than average propagation velocities on the wave front. This lead to longer ignition delays for large amounts of gas passing through the wave, giving rise to the unburned pockets of gas observed experimentally. Authors would like to acknowledge NSERC and Shell for project funding.

  11. LES of wind turbine wakes: Evaluation of turbine parameterizations

    NASA Astrophysics Data System (ADS)

    Porte-Agel, Fernando; Wu, Yu-Ting; Chamorro, Leonardo

    2009-11-01

    Large-eddy simulation (LES), coupled with a wind-turbine model, is used to investigate the characteristics of wind turbine wakes in turbulent boundary layers under different thermal stratification conditions. The subgrid-scale (SGS) stress and SGS heat flux are parameterized using scale-dependent Lagrangian dynamic models (Stoll and Porte-Agel, 2006). The turbine-induced lift and drag forces are parameterized using two models: an actuator disk model (ADM) that distributes the force loading on the rotor disk; and an actuator line model (ALM) that distributes the forces on lines that follow the position of the blades. Simulation results are compared to wind-tunnel measurements collected with hot-wire and cold-wire anemometry in the wake of a miniature 3-blade wind turbine at the St. Anthony Falls Laboratory atmospheric boundary layer wind tunnel. In general, the characteristics of the wakes simulated with the proposed LES framework are in good agreement with the measurements. The ALM is better able to capture vortical structures induced by the blades in the near-wake region. Our results also show that the scale-dependent Lagrangian dynamic SGS models are able to account, without tuning, for the effects of local shear and flow anisotropy on the distribution of the SGS model coefficients.

    The OLYMPUS and ACTS satellites both provide opportunities for 10 to 30 GHz propagation measurements. The spacecraft are sufficiently alike that OLYMPUS can be used to test some prototype ACTS equipment and experiments. Data are particularly needed on short term signal behavior and in support of uplink power control and adaptive forward error correction (FEC) techniques. The Virginia Tech Satellite Communications Group has proposed a set of OLYMPUS experiments including attenuation and fade rate measurements, data communications, uplink power control, rain scatter interference, and small-scale site diversity operation. A digital signal processing receiver for the OLYMPUS and ACTS beacon signals is being developed.

    Society is vulnerable to extreme weather events and, by extension, to human impacts on future events. As climate changes weather patterns will change. The search is on for more effective methodologies to aid decision-makers both in mitigation to avoid climate change and in adaptation to changes. The traditional approach uses ensembles of climate model simulations, statistical bias correction, downscaling to the spatial and temporal scales relevant to decision-makers, and then translation into quantities of interest. The veracity of this approach cannot be tested, and it faces in-principle challenges. Alternatively, numerical weather prediction models in a hypothetical climate setting can provide tailored narratives for high-resolution simulations of high-impact weather in a future climate. This 'tales of future weather' approach will aid in the interpretation of lower-resolution simulations. Arguably, it potentially provides complementary, more realistic and more physically consistent pictures of what future weather might look like.

    Introduction Le mobilier scolaire et la posture assise en classe sont souvent impliqués dans l'apparition des douleurs rachidiennes, influant de fait sur la qualité des tâches réalisées par les apprenants. Aucune étude n'a encore vérifié le degré d'adéquation entre les caractéristiques du mobilier et celles des écoliers au Bénin. L'objectif de cette étude transversale est donc de déterminer la relation entre les dimensions des table-bancs utilisées en classe et les mesures anthropométriques des écoliers au Bénin. Methods Elle a été réalisée avec un échantillon probabiliste de 678 écoliers, âgés de 4 à 17 ans. Les mesures anthropométriques des écoliers et les mensurations relatives aux longueurs, largeurs et hauteurs des table-bancs ont été mesurées, puis intégrées aux équations proposées dans la littérature. Les pourcentages des valeurs situées hors des limitesacceptables, dérivées de l'application des équations ont été calculés. Results La largeur et la hauteur des table-bancs utilisées par les écoliers étaient plus élevées (p < 0,05) que les valeurs de référence recommandées par les structures officielles de contrôle et de production des mobiliers scolaires au Bénin. Quel que soit le sexe, il y avait une inadéquation entre la largeur du banc et la longueur fesse-poplité, puis entre la hauteur de la table et la distance coude-bancdes écoliers. Conclusion Les résultats suggèrent de prendre en compte l’évolution des mesures anthropométriques des écoliers dans la confection des table-bancs, afin de promouvoir de bonnes postures assises en classe et de réduire le risque de troubles du rachis.

    This Analysis/Model Report (AMR) documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain (YM), Nevada (Figure l), the site of a potential repository for high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this AMR provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the infiltration model (USGS 2000) and for the total system performance assessment for the Site Recommendation (TSPA-SR) at YM. Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one method, among many, of establishing upper and lower bounds for future climate estimates. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog.

    The US Department of Energy`s (DOE) changing mission, coupled with the need to apply appropriate cleanup standards for current and future environmental restoration, prompted the need for a process to determine preferred Future Land Uses for DOE-owned sites. DOE began the ``Future Land Use`` initiative in 1994 to ensure that its cleanup efforts reflect the surrounding communities` interests in future land use. This plan presents the results of a study of stakeholder-preferred future land uses for the Brookhaven National Laboratory (BNL), located in central Long Island, New York. The plan gives the Laboratory`s view of its future development over the next 20 years, as well as land uses preferred by the community were BNL ever to cease operations as a national laboratory (the post-BNL scenario). The plan provides an overview of the physical features of the site including its history, topography, geology/hydrogeology, biological inventory, floodplains, wetlands, climate, and atmosphere. Utility systems and current environmental operations are described including waste management, waste water treatment, hazardous waste management, refuse disposal and ground water management. To complement the physical descriptions of the site, demographics are discussed, including overviews of the surrounding areas, laboratory population, and economic and non-economic impacts.

    1996-01-01

    Direct numerical simulation of turbulent reacting flows places extreme demands on computational resources. At the present time, simulations can be performed only for greatly simplified reaction systems and for very low Reynolds numbers. Direct simulation of more realistic cases occurring at higher Reynolds number and including multiple species and numerous chemical reactions will exceed available computational resources far into the future. Because of this, there is a clear need to develop the technique of large eddy simulation for reacting flows. Unfortunately this task is complicated by the fact that combustion arises from chemical reactions that occur at the smallest scales of the flow. Capturing the large-scale behavior without resolving the small-scale details is extremely difficult in combustion problems. Thus LES modeling for turbulent combustion encounters difficulties not present in modeling momentum transport, in which the main effect of the small scales is to provide dissipation. The difficulty is more pronounced in premixed combustion, where detailed chemistry plays an essential role in determining the flame speed (or overall burning rate); in nonpremixed combustion infinite rate chemistry can be assumed, eliminating the small scale features to a first approximation.

    Contexte : Etats-Unis.Cadre : On ne sait pas si les caractéristiques d'un cas de tuberculose (TB) ou du patient permettent de prévoir la probabilité de contamination dans l'avenir.Objectif : Estimer la probabilité de cas présentant un génotype similaire dans le même conté et dans une période de 2 ans suivant le cas index.Schéma : Nous avons étudié tous les cas de TB avec génotypage déclarés aux Etats-Unis entre 2004 et 2010. Les scores prédictifs ont été calculés en fonction des caractéristiques du patient en divisant le nombre de patients qui n'étaient pas le dernier cas d'un groupement de génotypes au niveau d'un conté par le nombre total de patients.Résultats : Le risque global de nouveau cas lié à un autre cas était de 30,8% pendant les 2 années suivant l'année de déclaration de tout nouveau cas. Ces contaminations ont été détectées dans 34,7% des circonstances après diagnostic d'un cas à frottis positif, 51,9%, après diagnostic d'un patient sans domicile fixe et 45,2%, après diagnostic d'un patient toxicomane. Les scores prédictifs variaient en fonction de l'ethnie (Blancs 13,9% ; Amérindiens/Hawaïens 43,8%), l'âge (>65 ans 13,1% ; 0–4 ans 43%) et étaient plus élevé chez les patients nés aux Etats-Unis.Conclusion: Les facteurs comportementaux et socio-démographiques peuvent contribuer à prévoir la probabilité d'infection de cas dans le futur et peuvent servir à prioriser les recherches de sujets contacts.

    L'objectif de cette étude est de déterminer la fréquence, de décrire les circonstances de découverte, les signes cliniques et paracliniques, la composition chimique des calculs prélevés et les difficultés rencontrées dans le traitement des lithiases urinaires. Notre étude a été rétrospective sur une période de six ans (janvier 2005 à décembre 2010) et a eu pour cadre le CHUP-CDG et a concerné 67 patients âgés de moins de 15 ans opérés pour lithiases urinaires. Les calculs de la dernière année au nombre de douze ont fait l'objet d'une analyse spectrophotométrique. La lithiase urinaire figure parmi les dix premières pathologies du service de chirurgie et représente 1,32% des hospitalisations. L’âge moyen de nos patients est de deux ans et varie de 6 mois à 14 ans. La symptomatologie de la lithiase urinaire est polymorphe. Le diagnostic des lithiases urinaires a été essentiellement radiologique (ASP) dans 87, 50 des cas. Les localisations les plus fréquentes sont: vésicales (49,25%) et pyéliques (46,26%). L'ECBU a révélé une infection urinaire chez 9 patients. Les germes le plus fréquemment rencontrés sont: Klebsiella pneumoniae pneumoniae (22,22%) et staphyloccocus aureus (22,22%). Les difficultés du traitement sont dues à la modicité de nos moyens diagnostiques et à la nature chimique des calculs et le traitement a été dans tous les cas chirurgical. La composition chimique est dominée par les sels calciques notamment les oxalates, les phosphates et les carbonates. PMID:26175840

    Nous avons fabrique et etudie des cristaux photoniques bidimensionnels et tridimensionnels. Les cristaux 3D sont constitues de microbilles de polystyrene autoassemblees. La structure inverse en BaTiO3 a ete aussi fabriquee, ou l'on remplace l'espace entre les microbilles par du BaTiO3, alors que les microbilles sont eliminees. Nous avons essaye en particulier de comprendre les differents phenomenes qui influencent la cristallisation de ces structures afin d'obtenir des films de meilleure qualite. Les cristaux bidimensionnels, constitues de cylindres vides imbibes dans un semiconducteur (As2S3 ou Si), sont obtenus par holographie laser. Nous avons montre que cette technique est tres interessante pour la production en serie de ces structures. Des guides d'ondes, des coupleurs, et des jonctions Y, imbibes dans des cristaux photoniques bidimensionnels, ont aussi ete fabriques. Des mesures optiques et des simulations numeriques ont ete menees dans le but de caracteriser ces structures.

  4. Future Climate Analysis

    This Analysis/Model Report (AMR) documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain (YM), Nevada (Figure 1), the site of a potential repository for high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this AMR provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the infiltration model (USGS 2000) and for the total system performance assessment for the Site Recommendation (TSPA-SR) at YM. Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one method, among many, of establishing upper and lower bounds for future climate estimates. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog. Revision 00 of this AMR was prepared in accordance with the ''Work Direction and Planning Document for Future Climate Analysis'' (Peterman 1999) under Interagency Agreement DE-AI08-97NV12033 with the U.S. Department of Energy (DOE). The planning document for the technical scope, content, and management of ICN 01 of this AMR is the ''Technical Work Plan for Unsaturated Zone (UZ) Flow and Transport Process Model Report'' (BSC 2001a). The scope for the TBV resolution actions in this ICN is described in the ''Technical Work Plan for: Integrated Management of Technical Product Input Department''. (BSC 2001b, Addendum B

    Résumé Objectif Étudier les caractéristiques et complications cliniques de la consommation à risque de cannabis et du trouble de consommation de cannabis, et présenter un protocole en cabinet pour le dépistage, l’identification et la prise en charge de ces problèmes. Sources des données Une recherche des essais contrôlés, des études d’observation et des révisions sur l’usage de cannabis par les adolescents et les jeunes adultes; les méfaits psychiatriques et médicaux liés au cannabis; le trouble de consommation de cannabis et son traitement; et les lignes directrices sur la consommation à faible risque de cannabis a été effectuée dans PubMed. Message principal Les médecins doivent questionner tous leurs patients quant à leur usage de cannabis. Ils doivent questionner plus souvent les adolescents et jeunes adultes de même que les personnes qui présentent un risque élevé de problèmes liés au cannabis (qui ont un trouble psychiatrique ou de consommation de drogue concomitant). Les problèmes pouvant être causés par le cannabis, comme les troubles de l’humeur, la psychose et les symptômes respiratoires, devraient susciter des questions sur la consommation de cannabis. Aux patients qui rapportent un usage de cannabis, les médecins devraient poser des questions sur la fréquence et la quantité consommée, la présence de symptômes de tolérance ou de sevrage, les tentatives de réduire leur consommation et la présence de problèmes liés au cannabis. Les usagers à faible risque fument, inhalent ou ingèrent le cannabis occasionnellement sans aucun signe de dysfonctionnement scolaire, professionnel ou social; les personnes dont l’usage est problématique consomment tous les jours ou presque tous les jours, ont de la difficulté à réduire leur consommation et leur fonctionnement scolaire, professionnel et social est perturbé. Les médecins devraient offrir à tous les patients dont l’usage est problématique des conseils

  6. Long-acting steroid contraceptive technology.

    Grubb, G

    1991-01-01

    Long-acting steroid contraceptive technologies that have either been recently approved or are currently under study are reviewed and the status of contraceptive research in the US is noted. The benefits and drawbacks, as well as the duration and possible cost, of each method are discussed. Approved by the Food and Drug Administration on December 10, 1990, Norplant is reportedly the first new contraceptive technology available to women in the US since the 1960s. This implant delivery system, which lasts up to 5 years, is cheaper than the pill and nearly as effective as sterilization. Study is currently under way on other multiyear, nonbiodegradable and biodegradable implants. Although already used by 4 million women worldwide, the long-acting injectable Depo-Provera has yet to be approved for use in the US. 5 new types of injectables are being developed. Steroid-containing IUDs have been in the market for some time, and current research is attempting to increase their contraceptive life beyond 1 year. Contraceptive developers are also exploring transdermal delivery systems, vaginal rings, and buccal and sublingual delivery. It is considered misleading to call Norplant the first new contraceptive introduced since the pill. Over the past 20 years, virtually every contraceptive has been significantly improved, developments that have enhanced the contraceptive options of couples. Because new contraceptive technologies are increasingly complex, their development is much slower. Consequently, it is concluded that in the foreseeable future, the demand for more acceptable contraceptives will be met through improvements of currently available technologies.

    Pour discuter les liens entre épilepsie et psychose, les auteurs rapportent l'observation d'une fille âgée de 22 ans, traitée pour épilepsie fronto-temporale, adressée en psychiatrie pour des hallucinations sensorielles et cénesthésiques et un délire mystique et d'influence, apparus secondairement et non améliorés par le traitement antiépileptique. Les symptômes psychotiques, chez l’épileptique, peuvent entrer dans le cadre de psychoses intercritiques, post-critiques ou alternatives. Pour le cas rapporté, les symptômes psychotiques étaient intercritiques et chroniques. Il s'agissait vraisemblablement d'une psychose schizophréniforme. Dans ce type de psychose, une indifférence affective et une restriction des activités sont rarement rencontrés, alors que les fluctuations rapides de l'humeur sont fréquentes. Les thématiques délirantes sont assez souvent mystiques, alimentées par des hallucinations auditives et par des hallucinations visuelles inhabituelles. Les troubles négatifs sont rares. Les psychoses épileptiques n'ont pas été identifiées comme des entités nosographiques dans les systèmes de classification psychiatrique (DSM-IV et CIM-10), ce qui pose un problème de reconnaissance de ces troubles. Une collaboration entre psychiatre et neurologue devient ainsi nécessaire pour mieux comprendre cette comorbidité complexe, éviter les erreurs diagnostiques et optimiser la prise en charge.

  18. The future of hydrogeology

    Voss, Clifford I.

    2005-01-01

    “The Future of Hydrogeology” would seem to be an overly ambitious topic for a theme issue of Hydrogeology Journal or for any other journal. Only a modicum of common sense and experience provides the insight that predicting the future of a science is a task fraught with uncertainty that should be approached with caution and humility. Please be assured that the intent of this issue of the journal is not to predict the future but rather to instigate discussion and to inspire creative thinking about hydrogeology. In their articles, authors have presented personal opinions concerning the future evolution of their subjects based on their experience. This is an acceptable approach, considering that any view of the future can be no more than an educated guess. Most authors have given their opinion after an expert and insightful review of the evolution of their subject to the present time or after reviewing the current state of knowledge or practice of their subject. Consequently, this issue of the Hydrogeology Journal provides an exciting view of potential developments in crucial aspects of hydrogeology founded upon developments to date.

    2016-04-01

    The new UCLALES-SALSA model, which uses a sectional representation of aerosols and cloud droplets, is compared against the LES configuration of the established WRF-Chem model. Two configurations of WRF-Chem are compared: the first using the sectional MOSAIC aerosol representation, and the second using the modal MADE/SORGAM representation. Both sets of WRF-Chem simulations use the two-moment Morrisson bulk cloud scheme. Wherever possible, the three sets of simulations have identical processes and initial conditions. By comparing UCLALES-SALSA against an established model in an ideal scenario, we demonstrate that the new model provides a realistic representation of warm cloud processes. The two configurations of WRF-Chem make it possible (to an extent) to isolate whether differences in model outputs are due to meteorological or microphysical effects.

  1. Etude des effets du martelage repetitif sur les contraintes residuelles

    NASA Astrophysics Data System (ADS)

    Hacini, Lyes

    L'assemblage par soudage peut engendrer des contraintes residuelles. Ces contraintes provoquent des fissurations prematurees et un raccourcissement de la duree de vie des composants. Dans ce contexte, le martelage robotise est utilise pour relaxer ces contraintes residuelles. Trois volets sont presentes: le premier est l'evaluation des effets des impacts unitaires repetes sur le champ de contraintes developpe dans des plaques d'acier inoxydable austenitique 304L vierges ou contenant des contraintes residuelles initiales. Dans la deuxieme partie de ce projet, le martelage est applique grace au robot SCOMPI. Les contraintes residuelles induites et relaxees par martelage sont ensuite mesurees par la methode des contours, qui a ete adaptee a cet effet. Dans la troisieme partie, le martelage est modelise par la methode des elements finis. Un modele axisymetrique developpe grace au logiciel ANSYS permet de simuler des impacts repetes d'un marteau elastique sur une plaque ayant un comportement elastoplastique.

  2. A Hybrid RANS/LES Approach for Predicting Jet Noise

    NASA Technical Reports Server (NTRS)

    Goldstein, Marvin E.

    2006-01-01

    Hybrid acoustic prediction methods have an important advantage over the current Reynolds averaged Navier-Stokes (RANS) based methods in that they only involve modeling of the relatively universal subscale motion and not the configuration dependent larger scale turbulence. Unfortunately, they are unable to account for the high frequency sound generated by the turbulence in the initial mixing layers. This paper introduces an alternative approach that directly calculates the sound from a hybrid RANS/LES flow model (which can resolve the steep gradients in the initial mixing layers near the nozzle lip) and adopts modeling techniques similar to those used in current RANS based noise prediction methods to determine the unknown sources in the equations for the remaining unresolved components of the sound field. The resulting prediction method would then be intermediate between the current noise prediction codes and previously proposed hybrid noise prediction methods.

    Introduction Le cancer au Maroc représente un problème majeur de santé publique, sa prise en charge doit être globale, active et complète pour tous les patients. L'objectif de ce travail était d'estimer la fréquence des perdus de vue « PDV » en oncologie au Maroc durant la première année de suivi et de déterminer les facteurs associés à ce problème. Méthodes Par une étude rétrospective portant sur 2854 dossiers de malades hospitalisés dans les trois principaux centres d'oncologie au Maroc depuis janvier 2003 jusqu’à juin 2007 et concernant les cinq principales localisations de cancer au Maroc, nous avons cherché la date des dernières nouvelles des patients ayant un recul de 18 mois minimum afin de déterminer le statut de ces malades après un an de suivi. Résultats La moyenne d’âge était de 52±14 ans, une proportion féminine de 63%, les sujets actifs constituaient 28%, les mariés 71%, les analphabètes 51%, 70% des patients habitaient en milieu urbain et seulement 11% des malades disposaient d'une couverture sociale. La localisation cancéreuse la plus fréquente était le poumon (23,8%) suivie du colon-rectum (23,5%) puis le col (21,9%), le sein (20,4%) et les lymphomes (10,4%). Le taux des «PDV» à un an de suivi était de 48%, ce statut était significativement lié au sexe, à l’âge, au NSE et au statut matrimonial. Sur le plan médical, le statut «PDV» était lié à la localisation du cancer, au stade de diagnostic et au type de traitement reçu. Conclusion Notre étude a mis en évidence la grande ampleur du problème des PDV en cancérologie au Maroc ainsi que ces déterminants. Ces résultats incitent tous les acteurs dans le domaine de la cancérologie à collaborer ensemble pour prendre les mesures qui s'imposent pour y pallier PMID:25400850

  4. Cryotanks in future vehicles

    NASA Astrophysics Data System (ADS)

    Heydenreich, R.

    Cryogenic storage of liquid hydrogen and oxygen is a need in future transportation systems. Therefore, MAN Technologie is studying various concepts for cryogenic tanks made of carbon reinforced plastics (CFRP) material. For space application the demand of a CFRP cryotank derives from the mechanical loads in combination with the thermal environment. Mass saving has priority for single stage launchers. In order to separate the influence of complex requirements on the tank components test samples are proposed with the help of scaling factors. For future aircraft the need for replacement of kerosene is growing. Due to the storage conditions the insulation requirement is very stringent. For ground traffic there are relatively small and cheap tanks to be produced in future. An overview on all these applications is given. The advantage of composite in relation to metallic tanks is maximum for use in spacecraft.

  6. LES/RANS Simulation of a Supersonic Reacting Wall Jet

    NASA Technical Reports Server (NTRS)

    Edwards, Jack R.; Boles, John A.; Baurle, Robert A.

    2010-01-01

    This work presents results from large-eddy / Reynolds-averaged Navier-Stokes (LES/RANS) simulations of the well-known Burrows-Kurkov supersonic reacting wall-jet experiment. Generally good agreement with experimental mole fraction, stagnation temperature, and Pitot pressure profiles is obtained for non-reactive mixing of the hydrogen jet with a non-vitiated air stream. A lifted flame, stabilized between 10 and 22 cm downstream of the hydrogen jet, is formed for hydrogen injected into a vitiated air stream. Flame stabilization occurs closer to the hydrogen injection location when a three-dimensional combustor geometry (with boundary layer development resolved on all walls) is considered. Volumetric expansion of the reactive shear layer is accompanied by the formation of large eddies which interact strongly with the reaction zone. Time averaged predictions of the reaction zone structure show an under-prediction of the peak water concentration and stagnation temperature, relative to experimental data and to results from a Reynolds-averaged Navier-Stokes calculation. If the experimental data can be considered as being accurate, this result indicates that the present LES/RANS method does not correctly capture the cascade of turbulence scales that should be resolvable on the present mesh. Instead, energy is concentrated in the very largest scales, which provide an over-mixing effect that excessively cools and strains the flame. Predictions improve with the use of a low-dissipation version of the baseline piecewise parabolic advection scheme, which captures the formation of smaller-scale structures superimposed on larger structures of the order of the shear-layer width.

    Les abcès froids de la paroi thoracique représentent une forme rare et inhabituelle de tuberculose extrapulmonaire. Sa fréquence est estimée à moins de 5% des tuberculoses ostéoarticulaires, évaluées elles-mêmes à 15% des tuberculoses extrapulmonaires. L'objectif de ce travail est de rapporter la prise en charge diagnostique et thérapeutique de cette localisation dans notre structure. Etude rétrospective portant sur 18 cas colligés au service des maladies respiratoires du centre hospitalier universitaire Ibn Rochd de Casablanca, sur une période de 13 ans. La moyenne d’âge était de 34 ans (21-57). Un antécédent de tuberculose traitée était relevé dans un cas. Le tableau clinique était révélé par l'apparition insidieuse d'une masse pariétale de taille, de consistance et de siège variables. A l'imagerie thoracique, l'abcès pariétal était associé à une lyse osseuse dans sept cas, une atteinte parenchymateuse et pleurale dans quatre cas chacune et des adénopathies médiastinales dans deux cas. La confirmation diagnostique était bactériologique et/ou histologique dans tous les cas. La sérologie du virus de l'immunodéficience humaineétait négative chez tous nos malades. L’évolution sous traitement antibacillaire couplé ou non à une résection chirurgicale était favorable chez tous nos malades. Malgré la fréquence de la tuberculose dans notre contexte, la localisation pariétale thoracique reste rare, survenant chez une population non immunodéprimée et non toxicomane, contrairement à ce qui est souvent rapporté dans la littérature. Les abcès froids tuberculeux représentent une forme rare de tuberculose extrapulmonaire dont l’évolution reste favorable sous traitement précoce et bien conduit. PMID:26113904

    Gooday, Graeme J N

    2005-12-01

    Futurist writing about technology emerged in the late 19th century at the same time as new kinds of electrical technology were making utopian futures seem practically attainable. Electrical writers and novelists alike thus borrowed from the popular "science" fiction of Jules Verne, Edward Bellamy and others to try to create self-fulfilling prophecies of a future in which electrical gadgets and machines met all major practical needs of civilization. To the extent that many parts of our world are populated by the hardware that they forecast, they succeeded in their goal.

  11. Future Climate Analysis

    SciTech Connect

    C. G. Cambell

    2004-09-03

    This report documents an analysis that was performed to estimate climatic variables for the next 10,000 years by forecasting the timing and nature of climate change at Yucca Mountain, Nevada, the site of a repository for spent nuclear fuel and high-level radioactive waste. The future-climate estimates are based on an analysis of past-climate data from analog meteorological stations, and this report provides the rationale for the selection of these analog stations. The stations selected provide an upper and a lower climate bound for each future climate, and the data from those sites will provide input to the following reports: ''Simulation of Net Infiltration for Present-Day and Potential Future Climates'' (BSC 2004 [DIRS 170007]), ''Total System Performance Assessment (TSPA) Model/Analysis for the License Application'' (BSC 2004 [DIRS 168504]), ''Features, Events, and Processes in UZ Flow and Transport'' (BSC 2004 [DIRS 170012]), and ''Features, Events, and Processes in SZ Flow and Transport'' (BSC 2004 [DIRS 170013]). Forecasting long-term future climates, especially for the next 10,000 years, is highly speculative and rarely attempted. A very limited literature exists concerning the subject, largely from the British radioactive waste disposal effort. The discussion presented here is one available forecasting method for establishing upper and lower bounds for future climate estimates. The selection of different methods is directly dependent on the available evidence used to build a forecasting argument. The method used here involves selecting a particular past climate from many past climates, as an analog for future climate. While alternative analyses are possible for the case presented for Yucca Mountain, the evidence (data) used would be the same and the conclusions would not be expected to drastically change. Other studies might develop a different rationale or select other past climates resulting in a different future climate analog. Other alternative

    Laforest, Guylaine

    L'etude de la stabilisation des poussieres de four a arc electrique (EAFD) par le laitier de haut-fourneau (GGBFS) et le ciment Portland (OPC) a ete realisee en trois parties. D'abord, la problematique de fixation du Cr dans les matrices cimentaires a ete etudiee en soumettant differents liants a des solutions de Cr lors d'essais de lixiviation en vrac et d'essais d'isothermes d'absorption. Ensuite, la caracterisation des EAFD a ete effectuee. Finalement, la stabilisation des EAFD dans les matrices cimentaires a ete etudiee en soumettant differents melanges liant-EAFD a des essais de lixiviation en vrac, de competition ionique, de solubilisation a differents pH et de lixiviation sur monolithes. Les resultats ont demontre que le OPC et le GGBFS sont efficaces pour la fixation du Cr. Les silicates de calcium hydrates, la chromatite et l'hydrocalumite ont ete identifiees comme etant des phases jouant un role dans la fixation du Cr. Les EAFD ont montre une mineralogie complexe, heterogene, riche en spinelles et oxydes metalliques. Un important pourcentage des metaux lourds (Cr, Zn, Ni et Pb) des EAFD a ete identifie lixiviable. Les EAFD etablissent un controle de solubilite sur ces metaux, mais ce controle n'est pas suffisant pour diminuer les concentrations en metaux du lixiviat sous les limites permises. Ainsi, les resulats des essais sur la stabilisation des EAFD ont demontre qu'il etait possible, avec le OPC et le GGBFS, de diminuer les concentrations en metaux lourds des lixiviats sous les limites acceptees. Les phases incorporant les metaux, ((Ni,Zn)Fe2O4, (Zn,Mo)O, Ni(OH)2 et Pb(OH) 2), ont ete determinees par SEM, XRD et par modelisation geochimique. L'hydrocalumite et le Cr(VI)-ettringite ont ete etablies comme etant des phases potentiellement capables de fixer le Cr. L'etude de la competition ionique a montre que la fixation du Cr par le GGBFS diminue legerement en presence du Pb. L'etude des monolithes, composes de EAFD et de OPC ou GGBFS et soumis a une

  13. The future and primary care.

    Primary care is about the intimate contact that takes place when a patient comes to the physician because that individual is concerned that he or she, son or daughter, parent or grandparent is sick, or is well and wants to stay well. Our history has been that we have paid attention to important problems but we have missed so far on primary care as a megatrend. As noted, one of our most important societal megatrends is proverty and how poverty places children at risk. Poverty and primary care are linked. The reality that all of our citizens do not have access to primary care is not just our failure but it is society's as well. We pediatricians face many problems. In developing solutions, historically our profession has never lost sight of the fact that we are a helping and caring discipline. We are an advocate for the poor, advocates for children, advocates for community, and that is a large job. But the challenge is real, and we do not have much time. Now is not the time to be timid. We need to achieve consensus, accepting and acting on the megatrend of securing the future for primary care.

  20. Future Flight Decks

    NASA Technical Reports Server (NTRS)

    Arbuckle, P. Douglas; Abbott, Kathy H.; Abbott, Terence S.; Schutte, Paul C.

    1998-01-01

    The evolution of commercial transport flight deck configurations over the past 20-30 years and expected future developments are described. Key factors in the aviation environment are identified that the authors expect will significantly affect flight deck designers. One of these is the requirement for commercial aviation accident rate reduction, which is probably required if global commercial aviation is to grow as projected. Other factors include the growing incrementalism in flight deck implementation, definition of future airspace operations, and expectations of a future pilot corps that will have grown up with computers. Future flight deck developments are extrapolated from observable factors in the aviation environment, recent research results in the area of pilot-centered flight deck systems, and by considering expected advances in technology that are being driven by other than aviation requirements. The authors hypothesize that revolutionary flight deck configuration changes will be possible with development of human-centered flight deck design methodologies that take full advantage of commercial and/or entertainment-driven technologies.

  10. Epigenetics and Future Generations.

    PubMed

    Del Savio, Lorenzo; Loi, Michele; Stupka, Elia

    2015-10-01

    Recent evidence of intergenerational epigenetic programming of disease risk broadens the scope of public health preventive interventions to future generations, i.e. non existing people. Due to the transmission of epigenetic predispositions, lifestyles such as smoking or unhealthy diet might affect the health of populations across several generations. While public policy for the health of future generations can be justified through impersonal considerations, such as maximizing aggregate well-being, in this article we explore whether there are rights-based obligations supervening on intergenerational epigenetic programming despite the non-identity argument, which challenges this rationale in case of policies that affect the number and identity of future people. We propose that rights based obligations grounded in the interests of non-existing people might fall upon existing people when generations overlap. In particular, if environmental exposure in F0 (i.e. existing people) will affect the health of F2 (i.e. non-existing people) through epigenetic programming, then F1 (i.e. existing and overlapping with both F0 and F2) might face increased costs to address F2's condition in the future: this might generate obligations upon F0 from various distributive principles, such as the principle of equal opportunity for well being.

Long-acting reversible contraception (LARC) methods, such as intrauterine devices and contraceptive implants, offer high continuation rates and very low failure rates, and are safe for use in most women. The provision of LARC methods to adolescent, young adult and nulliparous women is a relatively new concept that offers an innovative option for these populations.

  11. Patterns of esophageal inhibition during swallowing, pharyngeal stimulation, and transient LES relaxation. Lower esophageal sphincter.

    PubMed

    Pouderoux, Philippe; Verdier, Eric; Kahrilas, Peter J

    2003-02-01

    Lower esophageal sphincter (LES) relaxation and esophageal body inhibition co-occur during esophageal peristalsis but not necessarily during pharyngeal stimulation or transient LES relaxation (tLESR). This study examined these relationships and the impact on reflux. Nine young volunteers were studied. An artificial high-pressure zone (HPZ) was established, and pH was recorded 8 and 5 cm proximal to the LES. Pharyngeal stimulation was by water injection and gastric distension with liquid or gas. Peristalsis, pharyngeal stimulation, and spontaneous events were recorded. Swallowing relaxed the LES in 100% of trials (the HPZ in 80%) and caused no reflux. Pharyngeal stimulation relaxed the LES in two-thirds of trials, had no effect on the HPZ, and caused no reflux. Gastric distension was associated with 117 tLESRs, 48% with acid reflux, and 32% with gas reflux; there was no effect on the HPZ. We conclude that LES relaxation is a necessary but not sufficient condition for reflux. LES relaxation and esophageal body inhibition are independent events that may be concurrent (swallowing) or dissociated (tLESR).

  12. Corporate social responsibility of future radiology professionals.

    PubMed

    Collins, Sandra K; Collins, Kevin S

    2011-01-01

    Plagued by difficult economic times, many radiology managers may find themselves faced with ethical dilemmas surrounding ongoing organizational pressures to maintain high levels of productivity with restricted resources. This often times tests the level of moral resilience and corporate social consciousness of even the most experienced radiology professionals. A study was conducted to determine what Corporate Social Responsibility (CSR) orientation and viewpoint future radiology professionals may have. The results of the study indicate that these study participants may initially consider patient care more important than profit maximization. Study results indicate that these specific future radiology professionals will not need laws, legal sanctions, and intensified rules to force them to act ethically. However,they may need ongoing training as to the necessity of profit maximization if they seek the highest quality of care possible for their patients.

  13. Comparison of LES model produced and in-situ measured stratocumulus cloud microphysics

    NASA Astrophysics Data System (ADS)

    2015-12-01

    Large Eddy Simulation (LES) models are known to be a valuable tool that can be used to study microphysical, dynamical and radiative properties and their complex interactions in stratocumulus clouds since they can generate stratocumulus clouds realistically. These model generated properties were often compared with observations usually focusing on macroscopic features such as cloud depth and LWP. In this study we try to examine how good LES models are in re-producing cloud microphysical characteristics of stratocumulus clouds. After all if microphysics is not right, macroscopic, dynamic and radiative characteristics represented by the model cannot be fully trusted. The observation data are obtained from the G-1 aircraft measurements of marine stratocumulus clouds over the southeast Pacific near the coast of Chile during the Variability of the American Monsoon Systems Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx). Two LES models are used to simulate these clouds: one is CIMMS (Cooperative Institute for Mesoscale Meteorological Studies) LES and the other is WRF (Weather Research and Forecasting Model) LES. Both models are run in 3-D setting and employ bin microphysics to be appropriate for detailed cloud microphysics calculation. Comparison between observation and LES models could reveal intrinsic problems of the LES models in representing entrainment and mixing processes. The difference between the two LES models may reveal the intrinsic differences between the two models in representing large eddies and microphysical processes. Some preliminary results indicate that the CIMMS LES model tends to produce cloud microphysical relationships that are expected to occur when homogeneous mixing is dominant. More detail will be presented at the conference.

    Les corps étrangers (CE) représentent une pathologie fréquemment rencontrée en pratique ORL d'urgence. Ils peuvent constituer une urgence vitale par leur aspect ou leur siège. Nous présentons le bilan de dix ans sur la prise en charge des CE de la sphère ORL avec une revue de la littérature. Il s'agit d'une étude rétrospective entre Janvier 2004 et Décembre 2013, incluant tous les cas de CE des voies aéro-digestives supérieures et auriculaires colligés dans le service d'ORL au CHU Mohammed VI de Marrakech au Maroc. Sur les 1317 cas de CE de la sphère ORL colligés durant cette période, 80,48% concernaient les enfants. Le sex-ratio était de 1,5. L’âge moyen était de 12,92 ans. Les CE œsophagiens étaient les plus fréquents (47,53%). Les complications ont été rencontrées dans 11,69% des cas. Les CE dans la sphère ORL restent fréquents en pratique quotidienne surtout chez les enfants. Leur prise en charge nécessite une intervention rapide avec un matériel adapté et des médecins entrainés. La prévention reste la meilleure solution. PMID:26516392

  18. Self-defining future projections: exploring the identity function of thinking about the future.

    PubMed

    D'Argembeau, Arnaud; Lardi, Claudia; Van der Linden, Martial

    2012-01-01

    The act of projecting oneself into meaningful future events may significantly contribute to a person's sense of self and identity. Yet if the role of memories, in particular self-defining memories (SDMs), in grounding the self is now well established, the identity function of anticipated future events has received comparatively little attention. This article introduces the construct of self-defining future projection (SDFP) to address this issue. Two studies show that people can readily identify significant future events that they frequently think about and that convey core information about who they are as individuals. Furthermore, a person's particular style of constructing SDMs is similarly manifested in SDFPs, suggesting that both types of events can be used to ground the self. Notably, people who display a stronger tendency to extract meaning from their past experiences also reflect more about the potential implications of imagined future events. The results further demonstrate that SDMs and SDFPs both give rise to a strong sense of personal continuity over time and are meaningfully related to self-esteem. Together these findings lend support to the idea that a person's sense of self and identity is in part nourished by the anticipation of significant future events.
