  1. Current and future centrally acting antitussives☆

    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.

    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.

    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.

    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. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    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.

    PubMed

    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.

    1996-12-31

    Environmental regulations, including the Clean Air Act have a profound impact on the petroleum industry. For example, a recent study by the National Petroleum Council found that compliance with environment, health and safety regulations would cost the US refining and marketing industry some 37 billion dollars in the 1990s. This is greater than the entire 31 billion dollar asset base in 1990. The federal Clean Air Act is arguably the most comprehensive single piece of legislation ever passed by Congress. The act was originally passed in 1963 and has had several revisions, the most recent being in 1990. The act has provisions that cover many pollutants and different sources of pollution. This paper will only discuss limited portions of the clean air act that impact {open_quotes}mobile sources{close_quotes}, that is fuels and vehicles. In addition to a discussion of the background for several of these issues, the paper provides a report of the current status. Finally, some recommendations are made to improve the flexibility in the act and the regulations it requires.

  17. Future of liver disease in the era of direct acting antivirals for the treatment of hepatitis C

    PubMed Central

    Ponziani, Francesca Romana; Mangiola, Francesca; Binda, Cecilia; Zocco, Maria Assunta; Siciliano, Massimo; Grieco, Antonio; Rapaccini, Gian Lodovico; Pompili, Maurizio; Gasbarrini, Antonio

    2017-01-01

    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

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."

  4. 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.

  5. Where do we go from here?: The Federal Coal Leasing Amendments Act - past, present, and future

    SciTech Connect

    Kalen, S.

    1996-10-01

    The current federal coal program celebrates its twentieth anniversary on August 4, 1996. Aside from the mining of valuable mineral deposits from federal lands, an area so weathered that time has little meaning, the federal coal program stands almost alone as lasting longer than the other principal federal resource/energy programs. Currently, the antiquated hardrock mineral program is receiving national scrutiny. Not so with the federal coal program, which still operates in accordance with the Federal Coal Leasing Amendments Act of 1975 (FCLAA). The longevity of FCLAA is remarkable, but whether it reflects a sound policy that will carry us into the next century is an issue worth exploring. This article attempts to lay the foundation for such an examination by briefly canvassing the events and circumstances animating the passage of FCLAA, and then summarizing the primary provisions and subsequent regulatory implementation of the Act, with a focus on those aspects of the federal coal program that were designed to discourage speculation and spur development. This article concludes with some preliminary observations about the continued efficacy of FCLAA, tentatively suggesting that, while in hindsight the underlying concern prompting passage of FCLAA may be questionable, the anti-speculative and diligence provisions in FCLAA may still serve important natural resource policy objectives.

    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.

    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.

  9. The Future of Hemophilia Treatment: Longer-Acting Factor Concentrates versus Gene Therapy.

    PubMed

    Giangrande, Paul

    2016-07-01

    Gene therapy is the only novel technology that currently offers the prospect of a lasting cure for hemophilia and freedom from the burden of repeated injections. Recent data from a handful of patients who have undergone gene therapy for hemophilia B are very encouraging with a sustained factor IX (FIX) level of 0.05 IU/mL maintained for over 4 years. While this level is above the current usual target trough levels, it falls well short of the level that patients on prophylaxis with longer-acting products can expect. Prophylaxis is also associated with high peak levels, which permits patients to maintain an active lifestyle. A major barrier to widespread adoption of gene therapy is a high seroprevalence of antibodies to adeno-associated virus (AAV) vectors in the general population. Young children would be the best candidates for gene therapy in view of much lower seroprevalence to AAV in infants. A stable level of FIX early in life would prevent the onset of joint bleeds and the development of arthropathy. The recent experience with apolipoprotein tiparvovec (Glybera; uniQure, Amsterdam, the Netherlands) indicates that gene therapy is unlikely to prove to be a cheap therapeutic option. It is also quite possible that other new technologies that do not require viral vectors (such as stem cell therapy) may overtake gene therapy during development and make it redundant.

    International standards require avoiding any accidental break-ups of the spacecraft to prevent generation of space debris. Consequently, during disposal phase, a spacecraft shall "permanently deplete or make safe all remaining on-board sources of stored energy".These operations are called passivation of the spacecraft.The French Space Law includes these requirements in the Technical Regulation as follows for orbital vehicles: The systems must be designed, produced and implemented so that, following the disposal phases:• all the on-board energy reserves are permanently depleted or placed in such a condition that they entail no risk of generating debris,• all the means for producing energy on-board are permanently deactivated.To comply with these requirements for future satellites (SL), CNES has started technical activities to consolidate the corresponding design.Next, the French technical requirements will be detailed, the ways to comply will be explained for power systems and propulsion systems and examples of technical design will be given.

    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.

  19. LES versus DNS: A comparative study

    NASA Technical Reports Server (NTRS)

    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.

    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.

  4. Long-acting beta-agonists in the management of chronic obstructive pulmonary disease: current and future agents

    PubMed Central

    2010-01-01

    Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow limitation and debilitating symptoms. For patients with moderate-to-severe COPD, long-acting bronchodilators are the mainstay of therapy; as symptoms progress, guidelines recommend combining bronchodilators from different classes to improve efficacy. Inhaled long-acting β2-agonists (LABAs) have been licensed for the treatment of COPD since the late 1990s and include formoterol and salmeterol. They improve lung function, symptoms of breathlessness and exercise limitation, health-related quality of life, and may reduce the rate of exacerbations, although not all patients achieve clinically meaningful improvements in symptoms or health related quality of life. In addition, LABAs have an acceptable safety profile, and are not associated with an increased risk of respiratory mortality, although adverse effects such as palpitations and tremor may limit the dose that can be tolerated. Formoterol and salmeterol have 12-hour durations of action; however, sustained bronchodilation is desirable in COPD. A LABA with a 24-hour duration of action could provide improvements in efficacy, compared with twice-daily LABAs, and the once-daily dosing regimen could help improve compliance. It is also desirable that a new LABA should demonstrate fast onset of action, and a safety profile at least comparable to existing LABAs. A number of novel LABAs with once-daily profiles are in development which may be judged against these criteria. Indacaterol, a LABA with a 24-hour duration of bronchodilation and fast onset of action, is the most advanced of these. Preliminary results from large clinical trials suggest indacaterol improves lung function compared with placebo and other long-acting bronchodilators. Other LABAs with a 24-hour duration of bronchodilation include carmoterol, vilanterol trifenatate and oldaterol, with early results indicating potential for once-daily dosing in humans.

    2013-05-01

    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. © 2013 New York Academy of Sciences.

    ...In this Further Notice of Proposed Rulemaking (FNPRM), the Commission proposes rules to expedite access by telecommunications carriers and cable operators to utility poles. Proposed measures include adoption of a specific timeline for poles survey and make-ready work, use of outside contractors, and improving the availability of data. The FNPRM also proposes to improve the pole attachments enforcement process, and proposes ways to make attachment rates as low and uniform as possible consistent with section 224 of the Communications Act. These steps should lower both the cost of gaining access to utility poles and pole attachment rates. These actions are intended to remove impediments to the deployment of facilities and to increase delivery of broadband services.

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.

    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

    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

    C'est de tres loin le mecanisme predominant dans les applications therapeutiques du laser. En concentrant le flux lumineux sur une surface redui-te, le laser chauffe localement les tissus qui se retractent (coagulation) pour etre elimines ensuite (detersion) ; si on chauffe plus intensement, les tissus peuvent etre volatilises. La coagulation est utilisee soit pour detruire de petits phenomenes tumoraux qui seront elimines lors du processus de detersion, soit pour arreter une hemorragie (hemo-stase) ; dans ce cas la retraction thermique des tissus va provoquer la fermeture de la lumiere des vaisseaux qui seront secondairement obliteres par des caillots formes sur place (thrombose). Par volatilisation it est possible de detruire des phenomenes tumoraux plus importants que ceux at-teints lors d'une simple coagulation. Si la zone volatilisee est tres etroite (de 0,1 a 1 mm) on obtient un effet de coupe avec une excellente hemostase au niveau des berges. Certes ces deux processus - coagulation et volatilisation - peuvent etre obtenus par d'autres procedes : echauffement par contact (sonde thermique) ou effet Joule (courant electrique haute frequence). Le laser a l'avantage de ne necessiter aucun contact mecanique entre le vecteur d'energie et les tissus ; on peut alors predire correctement la repartition d'energie au niveau des tissus et les effets sont tres repro-ductibles. Par ailleurs, l'absorption tissulaire variant considerablement avec la longueur d'onde on peut choisir la source laser en fonction des effets desires.

    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 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.

  10. Validating LES for Jet Aeroacoustics

    Bridges, James

    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.

A brief review of data sources available is presented along with examples illustrating cross-facility and internal quality checks required of the data before it should be accepted for validation of LES.

    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.

    Although models of future sustainability often talk about effectively balancing economic, social and environmental imperatives or factors, in practice this typically remains an elusive ideal. This paper explores the exemplary possibilities but also dilemmas of a proposed initiative in the resource-rich but under-developed Filippino island province of Mindanao to achieve such a delicate balance in practice. This initiative by Raintrust Sustainable Ventures' proposes to link foreign investment in agricultural development to both the social advancement of local tribal peoples and the protection of large amounts of remaining wilderness areas. Such a case study provides an exemplary basis for discussing the challenge of achieving social and environmental as well as economic domains of 'future sustainability'. The crucial supporting role of information and geospatial technologies in the Raintrust plan will also be discussed.

    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.

    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.

    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

    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.

    An overview of the ACTS Experiments Program is presented. ACTS is being developed and will flight test the advanced technologies associated with: a Ka-band multibeam antenna, onboard signal processing and switching as well as laser communications. A nominal 3 yr experiments program is planned. Through the experiments program, the capabilities of the ACTS system will be made available to U.S. industry, university and government experimenters to test, prove the feasibility and evaluate the key ACTS system technologies. Communication modes of operation using the baseband processor and microwave switch matrix are presented, along with the antenna coverage pattern. Potential experiment categories are also presented and briefly discussed. An overall schedule of activities associated with the experiments program is outlined. Results of the ACTS Experiments Program will provide information vital to successful industry implementation of ACTS technology in a future operational system.

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

    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.

    In August 2013, the Pharmaceutical Society of Japan held the Third National Student Workshop in Tokyo. A total of 88 people-70 sixth-year undergraduate students from 70 universities, and 18 alumni who had participated in the First and the Second Workshops-attended this Workshop. The theme of this Workshop was "Contribution to medical care and society: How will I act as a pharmacist in the future?" The first day took the form of a World Café, with participants exchanging information on such topics as, "The purpose for choosing a pharmacy major, and my achievement status", "My favorite aspects of my college", and "My dreams and paths: Painting my future image". Later that day, participants discussed and gave presentations on the ways they would be contributing as pharmacists to society and medical care. On the second day, participants discussed and gave presentations on the efforts they would like to make as pharmacists to contribute to society and medical care. The final session was a general assembly for discussion on the ways they would be contributing as pharmacists to society and medical care. Throughout the two days, attendees participated in discussions with an awareness of their common ground, in that they all had national qualification in spite of different intended paths. In this article, 4 sixth-year students (their status at the time of the symposium) from the Workshop introduce outlines of the discussions and products from each group.

  12. Anisotropic grid adaptation in LES

    NASA Astrophysics Data System (ADS)

    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.

  13. Signal transduction in esophageal and LES circular muscle contraction.

    Contraction of normal esophageal circular muscle (ESO) in response to acetylcholine (ACh) is linked to M2 muscarinic receptors activating at least three intracellular phospholipases, i.e., phosphatidylcholine-specific phospholipase C (PC-PLC), phospholipase D (PLD), and the high molecular weight (85 kDa) cytosolic phospholipase A2 (cPLA2) to induce phosphatidylcholine (PC) metabolism, production of diacylglycerol (DAG) and arachidonic acid (AA), resulting in activation of a protein kinase C (PKC)-dependent pathway. In contrast, lower esophageal sphincter (LES) contraction induced by maximally effective doses of ACh is mediated by muscarinic M3 receptors, linked to pertussis toxin-insensitive GTP-binding proteins of the G(q/11) type. They activate phospholipase C, which hydrolyzes phosphatidylinositol bisphosphate (PIP2), producing inositol 1,4,5-trisphosphate (IP3) and DAG. IP3 causes release of intracellular Ca++ and formation of a Ca++-calmodulin complex, resulting in activation of myosin light chain kinase and contraction through a calmodulin-dependent pathway. Signal transduction pathways responsible for maintenance of LES tone are quite distinct from those activated during contraction in response to maximally effective doses of agonists (e.g., ACh). Resting LES tone is associated with activity of a low molecular weight (approximately 14 kDa) pancreatic-like (group 1) secreted phospholipase A2 (sPLA2) and production of arachidonic acid (AA), which is metabolized to prostaglandins and thromboxanes. These AA metabolites act on receptors linked to G-proteins to induce activation of PI- and PC-specific phospholipases, and production of second messengers. Resting LES tone is associated with submaximal PI hydrolysis resulting in submaximal levels of inositol trisphosphate (IP3-induced Ca++ release, and interaction with DAG to activate PKC. In an animal model of acute esophagitis, acid-induced inflammation alters the contractile pathway of ESO and LES. In LES circular

  5. 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).

  6. Les Johnson Views Interstellar Sail Material

    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.

    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

Sources de l’information Le présent article s’appuie sur certaines constatations tirées d’une recherche sur MEDLINE sur les testicules non descendus et les recommandations pour orchidopexie, et sur notre expérience à la Clinique d’urologie du Centre hospitalier pour enfants de l’est de l’Ontario à Ottawa, y compris un examen des recommandations à notre clinique pour testicules non descendus et les constatations de variantes normales par rapport aux cas chirurgicaux qui en résultent. Les titres MeSH anglais utilisés dans notre recherche sur MEDLINE étaient undescended testicle, retractile testicle, ectopic testicle, ascended testicle, referral and consultation et orchiopexy. Message principal Un testicule non descendu désigne l’absence réelle d’un testicule (ou des 2) de sa position normale dans le scrotum. Les testicules ectopiques et intra-abdominaux sont aussi absents du scrotum, mais les testicules intra-abdominaux y ont été présents à un certain moment du développement. Il importe de distinguer les différentes observations à l’examen testiculaire, puisque les testicules descendus et ascenseurs, ou rétractiles, sont pris en charge de manière conservatrice, tandis qu’une intervention chirurgicale rapide est indiquée dans les cas de testicules intra-abdominaux, ectopiques et non descendus. L’incertitude liée au diagnostic de testicule non descendu cause de l’anxiété, pourrait entraîner des examens d’imagerie non justifiés et allonger les listes d’attente pour une consultation auprès d’un spécialiste.

  11. Quantifying Numerical Dissipation due to Filtering in Implicit LES

    NASA Astrophysics Data System (ADS)

    Cadieux, Francois; Domaradzki, Julian Andrzej

    2015-11-01

    Numerical dissipation plays an important role in LES and has given rise to the widespread use of implicit LES in the academic community. Recent results demonstrate that even with higher order codes, the use of stabilizing filters can act as a source of numerical dissipation strong enough to compare to an explicit subgrid-scale model (Cadieux et al., JFE 136-6). The amount of numerical dissipation added by such filtering operation in the simulation of a laminar separation bubble is quantified using a new method developed by Schranner et al., Computers & Fluids 114. It is then compared to a case where the filter is turned off, as well as the subgrid-scale dissipation that would be added by the σ model. The sensitivity of the method to the choice of subdomain location and size is explored. The effect of different derivative approximations and integration methods is also scrutinized. The method is shown to be robust and accurate for large subdomains. Results show that without filtering, numerical dissipation in the high order code is negligible, and that the filtering operation at the resolution considered adds substantial numerical dissipation in the same regions and at a similar rate as the σ subgrid-scale model would.

  12. Numerical computations of turbulent flows; LES/SAS comparison

    NASA Astrophysics Data System (ADS)

    Ilie, Marcel; Smith, Stefan Llewellyn

    2010-11-01

    In aerodynamics, the unsteady fluctuations of the flow field can have a significant influence on stalled flow characteristics, or on the forces acting on different parts of the aircraft. In non-aerodynamic flows, there is a multitude of mixing problems such as piston engines or turbine blade cooling where steady Reynolds-Averaged Navier-Stokes (RANS) solutions are not adequate. On the other hand the unsteady Reynolds-Averaged Navier-Stokes (URANS) has proven to be insufficient. This is due to the highly dissipative nature of standard URANS. The use of Large Eddy Simulation (LES) methods is often not practical, due to the requirement of very fine grid resolution near walls. Direct Numerical Simulations (DNS) compute the flow field without further simplifications. However, due to a wide range of length and time scales present in turbulent flows, the use of DNS is still limited to low-Reynolds-number flows and relatively simple geometries. To combine the advantages of a URANS with the higher resolution of a LES, hybrid methods such as Detached Eddy Simulation (DES) or Scale Adaptive Simulation (SAS) are preferred. The present research concerns the suitability of SAS for the computation of highly separated flows. The results show that SAS is a promising approach for the computation of massively separated flows.

    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.

  17. 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

    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.

  19. DNS and LES of some engineering flows

    NASA Astrophysics Data System (ADS)

    Rodi, Wolfgang

    2006-02-01

    In this paper, direct numerical simulations (DNS) and large eddy simulations (LES) of three engineering flows carried out in the author's research group are presented. The first example, simulated both with DNS and LES, is the flow in a low-pressure turbine cascade with wakes passing periodically through the cascade channel. In this situation, the laminar-turbulent transition of the boundary layers on the blade surfaces, which is strongly influenced by the passing wakes, is of special interest. Next, LES of the flow past the Ahmed body is presented, which is a car model with slant back. In spite of the fairly simple geometry, the flow around the model has many features of the complex, fully 3D flow around real cars. The third example, for which LES is presented, is the flow past a surface mounted circular cylinder of height-to-diameter ratio of 2.5. In this case also complex 3D flow develops with interaction of various vortices behind the cylinder. By means of these examples, the paper shows that complex turbulent flows of engineering relevance can be predicted realistically by DNS and LES, albeit at large cost. The methods are particularly suited and superior to RANS methods for situations where unsteadiness like shedding and large-scale structures dominate the flow, and DNS has evolved into an important tool for studying transition mechanisms.

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.

    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.

  4. Merging RANS & LES approaches in submesoscale modeling

    NASA Astrophysics Data System (ADS)

    Fock, B. H.; Schluenzen, K. H.

    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.

Type d’étude Enquête qualitative par entrevues semi-dirigées. Contexte Midi-Pyrénées (France) et Auvergne (France). Participants Jeunes filles de 15 à 19 ans qui n’ayant pas vécu l’EG. Méthodes Le mode de recrutement de l’échantillon a été double : sélection des jeunes filles par la technique boule-de-neige et sélection par la technique d’échantillonnage ciblé jusqu’à l’obtention de la saturation des données tout en cherchant la variation maximale dans les profils des sujets. Les questions ouvertes portaient sur les sources d’informations, les connaissances, les critères de bon déroulement et l’imaginaire autour de l’EG. Le verbatim a fait l’objet d’une analyse longitudinale immédiate rassemblant le contexte (notes des chercheurs) et les idées principales de l’entretien. Une analyse transversale thématique a été réalisée. Principales constatations Une méconnaissance générale des jeunes filles sur l’EG entretenait l’imaginaire autour de cet examen perçu comme obligatoire. L’EG idéal, selon les jeunes filles interrogées, aurait lieu chez une jeune fille qui se sentirait prête, informée préalablement, pouvant être accompagnée selon son souhait. Cet examen se déroulerait dans un environnement chaleureux et confortable afin de diminuer le sentiment de vulnérabilité. La qualité du lien avec le médecin conditionnerait l’acceptation de cet examen par les jeunes filles. Conclusion Une consultation dédiée à l’information, préalable à la consultation où a lieu l’EG, permettrait de diminuer les appréhensions, d’améliorer les connaissances des jeunes filles et de favoriser le bon déroulement du futur premier EG tant pour le médecin que pour la patiente.

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

    NASA Astrophysics Data System (ADS)

    Redman, Andrew; Craft, Kyle; Aikens, Kurt

    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.

  1. A New Formulation for Hybrid LES-RANS Computations

    NASA Technical Reports Server (NTRS)

    Woodruff, Stephen L.

    2013-01-01

    Ideally, a hybrid LES-RANS computation would employ LES only where necessary to make up for the failure of the RANS model to provide sufficient accuracy or to provide time-dependent information. Current approaches are fairly restrictive in the placement of LES and RANS regions; an LES-RANS transition in a boundary layer, for example, yields an unphysical log-layer shift. A hybrid computation is formulated here to allow greater control over the placement of LES and RANS regions and the transitions between them. The concept of model invariance is introduced, which provides a basis for interpreting hybrid results within an LES-RANS transition zone. Consequences of imposing model invariance include the addition of terms to the governing equations that compensate for unphysical gradients created as the model changes between RANS and LES. Computational results illustrate the increased accuracy of the approach and its insensitivity to the location of the transition and to the blending function employed.

    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.

  10. Mesure du parametre acoustique non lineaire dans les solvants et dans les polymeres

    NASA Astrophysics Data System (ADS)

    Banchet, Julien

    Dans cette étude, une technique d'amplitude finie visant la mesure du paramètre non linéaire B/A fut mise au point puis appliquée à trois familles de solvants à savoir les 1- alkanols, les cétones et les esters, ainsi qu'à deux polymères. Par l'intermédiaire d'une lentille acoustique, un signal fut focalisé dans le milieu à caractériser et l'amplitude du second harmonique généré, mesurée. Le paramètre non linéaire put alors être calculé pour chacun des liquides et solides testés. Les résultats obtenus concernant les liquides permirent de démontrer la variation de B/A avec la longueur de chaîne et la dépendance de ce paramètre avec la vitesse du son. Un modèle fut par la suite établi puis appliqué aux 1-alkanols, obtenant une description de la variation de B/A à la vitesse du son conforme à nos résultats expérimentaux. Le même principe de mesure fut appliqué à deux polymères, montrant le potentiel de cette technique pour déterminer la valeur du paramètre non linéaire dans les solides.

    Résumé Objectif Cette recherche vise à documenter la prise en charge des troubles mentaux (TM) par les omnipraticiens. 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

    Advanced supersonic nozzle concepts are currently under investigation, utilizing multiple bypass streams and airframe integration to bolster performance and efficiency. This work focuses on the parametric study of a supersonic, multi-stream jet with aft deck. The single plane of symmetry, rectangular nozzle, displays very complex and unique flow characteristics. Flow visualization techniques in the form of PIV and schlieren capture flow features at various deck lengths and Mach numbers. LES is compared to the experimental results to both validate the computational model and identify limitations of the simulation. By comparing experimental results to LES, this study will help create a foundation of knowledge for advanced nozzle designs in future aircraft.

    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.

    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.

  19. Criteria for Modeling in LES of Multicomponent Fuel Flow

    NASA Technical Reports Server (NTRS)

    Bellan, Josette; Selle, Laurent

    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.

    Attendees have reported changing from being fearful to serene, from listless to energized, from disengaged to connected, and becoming markedly less anxious in a few weeks. Anecdotally, self-reported stress levels have been reduced by over 50% after just one class. Attendees learn not to be afraid of their feelings by working with emotions in a playful manner. When a person can act angry, but separate himself from his personal story, the emotional energy exists in a separate form that is not attached to specific events, and can be more easily dealt with and neutralized. Attendees are taught to "take out the emotional trash" through expressive comedy. They become less intimated by their own emotional intensity and triggers as they learn how even metaphorical buckets of anger, shame, guilt and hurt can be emotionally emptied. The added benefit is that this is accomplished without the disclosure of personal information of the requirement to reexperience past pain which can trigger its own cascade of stress.

  2. Evaluation of realistic LES simulations using remote-sensing forward operators

    A detailed understanding of clouds and their macrophysical structure is crucial to reduce the uncertainty of cloud feedbacks in current general circulation models (GCMs). Due to the coarse resolution of GCMs of O(100 km), clouds often have to be parameterised. Relevant cloud processes instead act on scales of O(100 m). Large-eddy simulations on huge domains with realistic weather forecast like boundary forcing are an emerging method to bridge this gap. But still careful evaluation based on observations is crucial to ensure realism of these LES simulations. We will present a comprehensive evaluation of the ICON-LES simulations at 156 m resolution covering central Europe. Observational reference is based on the remote-sensing measurements of the Jülich ObservatorY for Cloud Evolution (JOYCE) supersite. To better assess for uncertainties than at retrievals, physical consistent forward operators for a cloud radar, microwave radiometer and a simple LiDAR are applied on the model output. The high spatial and time resolution (up to 9 sec.) of the LES output allow for comparable synthetic observations with an unprecedented detail. For the first time a full synthetic Cloudnet supersite is created. One of the Cloudnet products is the cloud classification, which is one of the most intuitive and comprehensive observational product to gain detailed information about cloud type and structure. The cloud classification can now be derived from the LES, which is a powerful tool for investigating clouds. The simulated cloud radar observations show an overestimation of frozen hydrometeors in the upper troposphere, indicated by too high reflectivities. Small scale variability of the simulated water vapour microwave channels is well captured, which shows an added value of the LES. Rain events are too rare and the intensity is often overestimated by ICON, which is seen by less high reflectivity bands, whereas the reflectivity within the rain event is by 10 dbZ higher than of the

    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.

  4. 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.

    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.

  11. 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.

  16. 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

  18. 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.

    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.

  20. Advanced Communications Technology Satellite (ACTS)

    1989-01-01

    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.

  12. Les nouveaux résultats Chandra et XMM-Newton concernant les Noyaux Actifs de Galaxies

    NASA Astrophysics Data System (ADS)

    Porquet, 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

  13. Federal Employees' Compensation Act.

    PubMed

    Ladou, Joseph

    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.

  15. ACTS broadband aeronautical experiment

    NASA Technical Reports Server (NTRS)

    Abbe, Brian S.; Jedrey, Thomas C.; Estabrook, Polly; Agan, Martin J.

    1993-01-01

    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.

    Moujahid, Mountassir; Tajdine, Mohamed Tarik

    2011-01-01

    Etude rétrospective rapportant une série de kystes hydatiques rompus dans les voies biliaires colligés dans le service de chirurgie de l'hôpital militaire Avicenne à Marrakech. Entre 1990 à 2008, sur 536 kystes hydatiques du foie opérés dans le service, 120 étaient compliqués de rupture dans les voies biliaires soit 22,38%. Il y avait 82hommes et 38 femmes. L’âge moyen était de 35 ans avec des extrêmes allant de 10 à 60 ans. La clinique était dominée par la crise d'angiocholite ou une douleur du flanc droit. L'ictère était isolé dans huit cas. La fistule biliokystique était latente dans plus de 50% des cas. Le traitement a consisté en une résection du dôme saillant dans103cas (85,84%), une périkystectomie chez 11 malades (9,16%) et une lobectomie gauche dans six cas (5%). Le traitement de la fistule bilio kystique a consisté en une suture chez 36malades et un drainage bipolaire dans 25 cas, La déconnexion kysto-biliaire ou cholédocotomie trans hépatico kystique selon Perdomo était pratiquée dans 49cas et une anastomose bilio-digestive cholédoco-duodénale dans 10 cas. La durée moyenne d'hospitalisation était de 20jours. Nous déplorons deux décès par choc septique et un troisième par encéphalopathie secondaire à une cirrhose biliaire. La morbidité était représentée par huit abcès sous phrénique, douze fistules biliaires prolongées et deux occlusions intestinales. Les kystes hydatiques rompus dans les voies biliaires représentent la complication la plus grave de cette pathologie bénigne. Le traitement repose sur des méthodes radicales qui sont d'une efficacité reconnue, mais de réalisation dangereuse et les méthodes conservatrices, en particulier la déconnexion kysto-biliaire qui est une méthode simple et qui donne de bons résultats à court et à long terme.

  18. 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).

    Auger, Nathalie; Raynault, Marie-France

    2005-01-01

    With the advent of the Tobacco Act, tobacco marketing is now severely restricted in Canada. This article considers how the tobacco industry may conduct future marketing in order to circumvent the Tobacco Act. Past tobacco marketing strategies are discussed in light of how such strategies could be used in future marketing campaigns. In addition, this article highlights the need for private industries unrelated to tobacco to conduct socially responsible advertising so as to avoid inadvertently promoting tobacco.

    In Italy, anti-HCV drugs are provided free of charge by the National Health System. Since 2011, three drug regimens including a directly acting antiviral (DAA) are considered the gold standard for HCV treatment. However, these drugs add a significant cost (roughly €26,000) to the combination of pegylated-interferon-α/ribavirin (PEG-IFN/RBV), which before DAA represented the unique treatment. To provide the National Health System potential useful information, we estimated costs to provide anti-HCV drugs to treat a population experienced for PEG-INF/RBV. Genotype 1 HCV mono-infected or HIV/HCV co-infected individuals who were treated with PEG-IFN/RBV between 2008 and 2013 were included. The cost to treat these patients with PEG-IFN/RBV was calculated (cost 1). We also estimated costs if we had to treat these patients with a lead-in period of PEG-INF/RBV followed by PEG-IFN/RBV and a DAA in naïves (cost 2), in addition to cost 1 plus the estimated cost to re-treat with PEG-IFN/RBV and a DAA patients who had a relapse or a non response (cost 3). Moreover, all costs were normalized by SVR. Rates of foreseen response with DAA were obtained from literature data. The overall study population consisted of 104 patients. The rate of sustained virological response (SVR) was 55%, while it was estimated that SVR would be obtained in 75% of patients with a lead-in period with PEG-IFN/RBV followed by a DAA combination, and in 78% if this treatment is used to re-treat experienced patients with a DAA. Drug costs associated with these treatments were: €1,214,283 for cost 1, €3,474,977 for cost 2 and €3,002,095 for cost 3. Costs per SVR achieved were: €22,284 for cost 1, €44,643 for cost 2 and €38,322 for cost 3. Treatments including DAAs achieve a SVR in more patients than PEG-IFN/RBV but they cost around three times more than PEG-IFN/RBV alone regimens. Also, cost per SVR is almost twofold greater than PEG-IFN/RBV regimens. Therefore, it is mandatory to implement use

    This study investigates LES in meteorological applications that involve realistic background atmospheric environment. This is accomplished by coupling the mesoscale meteorological model WRF with the LES code by Sullivan et al (1994). In this context, the diurnally varying atmospheric boundary layer is simulated using the above mentioned LES code. Initial data of wind, temperature, humidity, TKE vertical profiles and the surface forcing (heat/humidity fluxes) are taken from a WRF simulation in two different sites in flat regions. The geostrophic forcing is computed at given isobaric levels by calculating the horizontal gradients of the geopotential height in 9 squared grid points along the WRF grid. In particular in this work the various ways the geostrophic forcing can be calculated will be explored and results compared with those obtained with the LES code.

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.

  4. 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.

  5. LES tests on airfoil trailing edge serration

    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.

  10. 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.

    Svedhem, Håkan; Grinspoon, David

    In spite of all spacecraft that have visited our nearest planetary neighbor a large number of questions remain to be answered. Exploration of Venus is far from completed. In this chapter we summarize the most important questions to be answered, both in the short term, feasible with the technology of today, and those that only can be addressed in the medium to long term, after additional technology development. A large number of missions have been proposed in recent years but since Venus Express (Svedhem etal.2007) and the ill fated Akatsuki (Nakamura etal.2007) none of these have been selected for flight. Short descriptions of these mission proposals, as much as the information is openly available, are given in the following section. The next section deals with future ground based observations and joint space-ground observations. Finally the priorities for future missions, both for the benefit of improving on the theoretical models for atmospheric circulation, as dealt with in this book, and for an improved understanding of the evolution of Venus as a planet and of terrestrial planets in general, are discussed.

    Wilczek, Frank

    We are emerging from a period of consolidation in particle physics. Its great, historic achievement was to establish the Theory of Matter. This Theory will serve as our description of ordinary matter under ordinary conditions - allowing for an extremely liberal definition of ``ordinary'' - for the foreseeable future. Yet there are many indications, ranging from the numerical to the semimystical, that a new fertile period lies before us. We will discover compelling evidence for the unification of fundamental forces and for new quantum dimensions (low-energy supersymmetry). We will identify new forms of matter, which dominate the mass density of the Universe. We will achieve much better fundamental understanding of the behavior of matter in extreme astrophysical and cosmological environments. Lying beyond these expectations, we can identify deep questions that seem to call for ideas outside our present grasp. And there is still plenty of room for surprises.

    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

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.

    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.

    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

    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.

Les analyses correlees de la structure et de la magnetoresistance nous permettront d'emettre des conclusions sur l'influence des couches tampons entre l'interface et le substrat ainsi qu'entre les couches elles-memes sur le comportement magnetique des couches F/F. La troisieme partie est consacree aux systemes a Magneto-Resistance Geante (MRG) a base de Co et Ag. Nous allons etudier l'evolution de la microstructure suite a l'irradiation avec des ions Si+ ayant une energie de 1 MeV, ainsi que les effets de ces changements sur le comportement magnetique. Cette partie debutera par l'analyse des proprietes d'une multicouche hybride, intermediaire entre les multicouches et les materiaux granulaires. Nous analyserons a l'aide des mesures de diffraction, de relaxation superparamagnetique et de magnetoresistance, les evolutions structurales produites par l'irradiation ionique.

    A new modeling strategy called F-TACLES (Filtered Tabulated Chemistry for Large Eddy Simulation) is developed to introduce tabulated chemistry methods in Large Eddy Simulation (LES) of turbulent premixed combustion. The objective is to recover the correct laminar flame propagation speed of the filtered flame front when subgrid scale turbulence vanishes as LES should tend toward Direct Numerical Simulation (DNS). The filtered flame structure is mapped using 1-D filtered laminar premixed flames. Closure of the filtered progress variable and the energy balance equations are carefully addressed in a fully compressible formulation. The methodology is first applied to 1-D filtered laminar flames, showing the ability of the model to recover the laminar flame speed and the correct chemical structure when the flame wrinkling is completely resolved. The model is then extended to turbulent combustion regimes by including subgrid scale wrinkling effects in the flame front propagation. Finally, preliminary tests of LES in a 3-D turbulent premixed flame are performed. (author)

  17. LES SOFTWARE FOR THE DESIGN OF LOW EMISSION COMBUSTION SYSTEMS FOR VISION 21 PLANTS

    SciTech Connect

    Karl V. Meredith; Clifford E. Smith

    2004-07-01

    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.

  18. On integrating LES and laboratory turbulent flow experiments

    SciTech Connect

    Grinstein, Fernando Franklin

    2008-01-01

    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.

    Supersymmetric (SUSY) spectrum generators, decay packages, Monte-Carlo programs, dark matter evaluators, and SUSY fitting programs often need to communicate in the process of an analysis. The SUSY Les Houches Accord provides a common interface that conveys spectral and decay information between the various packages. Here, we propose extensions of the conventions of the first SUSY Les Houches Accord to include various generalizations: violation of CP, R-parity and flavor as well as the simplest next-to-minimal supersymmetric standard model (NMSSM).

  6. Perspectives on the Future of CFD

    NASA Technical Reports Server (NTRS)

    Kwak, Dochan

    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.

    La chirurgie de reconstruction acétabulaire est une technique qui consiste à combler les pertes de substance osseuse siégeant au niveau du cotyle. Il s'agit d'une étude rétrospective de 15 patients (16 cotyles), sur une période de 6 ans (2006- 2012). Dans douze cas il s'agissait de prothèse totales de la hanche de première intention et dans quatre cas il s'agissait de reprise cotyloïdienne de PTH. L’évaluation clinique préopératoire et postopératoire de tous nos patients a été effectuée par le score de Postel et Merle d'Aubigné. L’évaluation des pertes de substances osseuse du cotyle a été classée selon la classification de Paprosky. L’âge moyen de nos patients au moment de l'intervention a été de 57 ans avec des extrêmes allant de 20 ans à 76 ans. La greffe osseuse a été utilisée chez 12 de nos patients. La reconstruction prothétique a été utilisée chez 8 patients (anneau de Kerboul dans six cas et anneau de Burch-Schneider dans deux cas). Recul post opératoire moyen a été de 56 mois. L’évaluation radiologique a été basée sur les clichés radiologiques du bassin de face strict ainsi que des radiographies de la hanche opérée de face prenant la totalité de la prothèse. Nos résultats cliniques et radiologiques ont été jugé bon à très bon dans la majorité des cas. Pour nous, nous optant pour le recentrage-reconstruction car c'est lui qui s'approche le plus de l'anatomie et de la biomécanique normale de la hanche. PMID:26955415

  10. 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.

  11. ACT and Recovery: What We Know About Their Compatibility.

    PubMed

    Morse, Gary; Glass, Ashley M H; Monroe-DeVita, Maria

    2016-03-01

    While assertive community treatment (ACT) is a widely implemented evidence-based practice, the extent of its recovery orientation has been debated. A literature search identified 16 empirical articles studying recovery and ACT. These 16 studies were classified as involving stakeholder perceptions, interventions, or fidelity measurement. Stakeholders generally viewed ACT as being recovery oriented; research on both interventions and fidelity measurement showed promising approaches. Overall the literature yielded encouraging findings regarding ACT and recovery, though there remains a dearth of research on the topic. We discuss future directions for research and practice to ensure that ACT programs skillfully support recovery.

  14. Hybrid RANS/LES of round impinging jets

    NASA Astrophysics Data System (ADS)

    Kubacki, Slawomir; Rokicki, Jacek; Dick, Erik

    2011-12-01

    Fluid flow and heat transfer characteristics are presented for simulations of round impinging jets at two nozzle-plate distances H/D = 2 and 10 (D is the nozzle exit diameter) and two Reynolds numbers Re = 5000 and 70,000 with hybrid RANS/LES (Reynolds-averaged Navier-Stokes/Large Eddy Simulation), dynamic Smagorinsky LES and RANS k-ω models. Three k-ω based hybrid RANS/LES models are analyzed. With the hybrid RANS/LES models, improved heat transfer results are obtained, when compared to RANS, in the impact region and in the developing wall-jet region. For accurate predictions at low nozzle-plate distance, it is necessary to sufficiently resolve the formation and development of the near-wall vortices in the jet impingement region. At high nozzle-plate distance, it is important to capture the evolution and breakup of the unsteady vortices in the shear layer of the jet, so that realistic mean and fluctuating velocity profiles are obtained in the impact jet region.

  15. 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.

  17. Aero-optical predictions using wall-modeled LES

    NASA Astrophysics Data System (ADS)

    Kamel, Mohammed; Wang, Kan; Wang, Meng

    2014-11-01

    The accuracy of LES with wall-modeling for predicting aero-optical distortions is evaluated in turbulent boundary layers and flow over a cylindrical turret by comparing results with those from previous wall-resolved LES and experiments. For turbulent boundary-layer flows at Mach 0.5 and momentum-thickness Reynolds numbers up to 31000, the velocity statistics in the majority of the logarithmic layer and the wake region are well predicted with an equilibrium stress-balance model, but the level of density fluctuations and hence optical wavefront distortions are over-predicted. The causes for the over-prediction and model improvement are investigated. When wall-modeled LES is applied to compute the turbulent flow over a cylindrical turret with a flat window at Mach 0.5 and the experimental Reynolds number of 5 . 6 ×105 based on the cylinder radius, both the flow statistics and optical distortions induced by the separated shear layer agree well with experimental measurements and previous wall-resolved LES results at a lower Reynolds number. The incorporation of the pressure gradient effect in wall-model equations is shown to improve the prediction of the fluctuating density field and optical distortions.

  20. 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

  1. 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

  7. 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.

    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

    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.

    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.

    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. ODT Based Closure Model for Non-Premixed Combustion LES

    NASA Astrophysics Data System (ADS)

    Miles, Jeffery Scott

    An LES closure method for turbulent non-premixed combustion using data from standalone ODT simulations is developed and validated. An ODT simulation provides a complete view of turbulent combustion including detailed chemistry within a single dimension through spatially (in 1D) and temporally resolved solutions for thermo chemical scalars and a stochastic description of turbulent advection. A unique closure technique removes the limitations associated with prescribed FDF distributions by using the resolved ODT statistics to construct joint scalar distributions needed for LES closure. These distributions are combined with other ODT statistics to construct closure tables for filtered variables such as density and chemical source terms. The tabulated closure follows the classical integration over state-space combining joint distributions with statistics from dependent variables. The temperature and mixture fraction are considered for this joint FDF as they can be combined to provide a complete view of the chemical and thermal state of the overall system within a non-premixed combustion problem. The ODT simulations are used to extract filtered and unfiltered correlations representing FDF distributions for each of the state-defining scalars; and kernel density functions are used to convert the sample datasets into smooth distributions that represent FDFs found within ODT statistics. A stand-alone ODT simulation is configured to generate the statistics and data needed for the closure model construction. The ODT domain selected to match the target problem domain is a one-dimensional axisymmetric piloted jet. This configuration is capable of capturing many of the features of a turbulent jet diffusion flame much like a spatially resolved DNS simulation but at a fraction of the cost. For each realization, the state variables are filtered and stored in vector form with the "instantaneous" values for each term included in the unclosed set required in the LES domain. Model

    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.

    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.

    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.

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

    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.

    HISTORIQUE ET OBJECTIF : L’utilisation d’antipsychotiques augmente chez les enfants. Le présent article visait à orienter les cliniciens quant à la prise en charge clinique des effets secondaires extrapyramidaux des antipsychotiques de deuxième génération. MÉTHODOLOGIE : Les publications, les entrevues avec des informateurs clés et des échanges avec les membres d’un groupe de discussion et les partenaires ont permis de déterminer les principaux secteurs cliniques d’orientation et les préférences quant à la structure des présentes recommandations. Les membres responsables des lignes directrices ont reçu le projet de recommandations, ont évalué l’information recueillie grâce à une analyse bibliographique systématique et ont utilisé un processus de groupe nominal pour parvenir à un consensus quant aux recommandations thérapeutiques. Les lignes directrices contiennent une description des anomalies neurologiques souvent observées avec l’utilisation d’antipsychotiques ainsi que les recommandations sur le moyen d’examiner et de quantifier ces anomalies. Une démarche séquentielle sur la prise en charge des anomalies neurologiques est présentée. RÉSULTATS : On peut observer plusieurs types de symptômes extrapyramidaux attribuables à l’utilisation d’antipsychotiques chez les enfants, y compris la dystonie aiguë, l’akathisie, le parkinsonisme et la dyskinésie tardive, toutes induites par les neuroleptiques, de même que la dystonie tardive, l’akathisie tardive et les dyskinésies de sevrage. La forte majorité des données probantes sur le traitement des troubles du mouvement induits par les antipsychotiques proviennent de patients adultes atteints de schizophrénie. Étant donné le peu de données pédiatriques, les recommandations découlent de publications portant tant sur des adultes que sur des enfants. Compte tenu des limites de généralisation des données provenant de sujets adultes pour des enfants, il

  14. 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.

  15. Hydrogeology in North America: past and future

    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.

    We study the TAE interaction with alpha particle fusion products in ARIES ACT-I using the 1.5D quasilinear model. 1.5D uses linear analytic expressions for growth and damping rates of TAE modes evaluated using TRANSP pro les to calculates the relaxation of pressure pro les. NOVA- K simulations are conducted to validate the analytic dependancies of the rates, and to normalize their absolute value. The low dimensionality of the model permits calculating loss diagrams in large parameter spaces.

  17. Etude du champ magnetique dans les nuages moleculaires

    Houde, Martin

    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.

  1. Adaptive LES Methodology for Turbulent Flow Simulations

    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

    Frère, Ariane; Carton de Wiart, Corentin; Hillewaert, Koen; Chatelain, Philippe; Winckelmans, Grégoire

    2017-08-01

    Wall-resolved Large-Eddy Simulations (LES) are still limited to moderate Reynolds number flows due to the high computational cost required to capture the inner part of the boundary layer. Wall-modeled LES (WMLES) provide more affordable LES by modeling the near-wall layer. Wall function-based WMLES solve LES equations up to the wall, where the coarse mesh resolution essentially renders the calculation under-resolved. This makes the accuracy of WMLES very sensitive to the behavior of the numerical method. Therefore, best practice rules regarding the use and implementation of WMLES cannot be directly transferred from one methodology to another regardless of the type of discretization approach. Whilst numerous studies present guidelines on the use of WMLES, there is a lack of knowledge for discontinuous finite-element-like high-order methods. Incidentally, these methods are increasingly used on the account of their high accuracy on unstructured meshes and their strong computational efficiency. The present paper proposes best practice guidelines for the use of WMLES in these methods. The study is based on sensitivity analyses of turbulent channel flow simulations by means of a Discontinuous Galerkin approach. It appears that good results can be obtained without the use of a spatial or temporal averaging. The study confirms the importance of the wall function input data location and suggests to take it at the bottom of the second off-wall element. These data being available through the ghost element, the suggested method prevents the loss of computational scalability experienced in unstructured WMLES. The study also highlights the influence of the polynomial degree used in the wall-adjacent element. It should preferably be of even degree as using polynomials of degree two in the first off-wall element provides, surprisingly, better results than using polynomials of degree three.

  12. 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.

    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

    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.

    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

    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.

    2014-03-01

    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.

  9. 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.

  10. 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.

    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.

    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

  2. Highly-Resolved LES of the Stable Boundary Layer Over Terrain

    SciTech Connect

    Calhoun, R.; Cederwall, R.T.; Stevens, D.; Street, R.

    2000-05-31

    One of the most important scenarios for atmospheric modelers is the stable boundary layer (SBL). Airborne material released near the ground will likely be trapped near the ground in high concentrations due to the reduced dispersion in the SBL. Hence the SBL is often the worst case scenario for studies of health impacts from routine or accidental release of toxic materials to the atmosphere. Unfortunately the SBL is very challenging to understand and model correctly. There is also a limited number of field studies with which to verify models, although recent studies (such as CASES-99) are promising. It is difficult for traditional Reynolds-averaged models of turbulence to capture the weak, spatially- and temporally-varying fluctuations that contribute to dispersion the SBL. Large-eddy simulation (LES) has become a promising approach study the SBL because much of the dynamical structure is explicitly resolved and allowed to develop according to the full equations of motion. The presence of topography further complicates the simulation of SBL flows. The drainage flows that develop as the surface cools must be resolved, along with their interaction with other drainage flows of varying scales and the main forcing (synoptic scale) flow. In this study, we have used LES techniques to simulate flows in complex terrain during the development of the SBL at night. We have begun to evaluate the effects of resolution on the simulations, though this effort is continuing at the time of this writing. Simulations are conducted for the area around Salt Lake City, where several field activities are planned for the future. The study will be extended to the small scale terrain associated with the CASES-99 experiment, and comparisons made with observations.

  4. LES validation for contaminant transport in urban areas

    NASA Astrophysics Data System (ADS)

    Hertwig, D.; Leitl, B.; Schatzmann, M.; Patnaik, G.

    2010-09-01

    Contaminant transport in urban areas poses a major challenge with respect to its simulation with computational fluid dynamics (CFD) models. The use of time-resolved approaches like large-eddy simulation (LES) can provide insight into transient flow and dispersion regimes, which are strongly influenced by the urban geometry. LES models have the potential to resolve the characteristic unsteady flow features and their impact on plume dynamics, whereas standard industrial codes based on Reynolds-averaged Navier-Stokes (RANS) equations can only yield steady state solutions. However, the potential to simulate the energetically dominating part of an inherently unsteady turbulent flow with LES also sets higher requirements for validation strategies. This includes that the evaluation of the model performance must go beyond comparisons of first and second order statistics which were adequate for RANS models and currently provide the basis for most of the validation metrics used as a standard. With regard to an a posteriori validation of model results for atmospheric boundary layer (ABL) flow and dispersion in complex geometry, laboratory data from boundary-layer wind tunnels are of special value. Since inflow and boundary conditions are well-defined, systematic laboratory studies provide high statistical confidence levels of measured quantities. The potential of field measurements - in this regard - is limited due to the natural atmospheric variability. In order to verify the realistic simulation of the spatio-temporal behavior of turbulent eddies, transient flow phenomena have to be characterized in experimental validation data sets as well. This topic is closely linked to structure identification and the characterization of organized motions in ABL flows, for which advanced analysis strategies like wavelet transforms, orthogonal decomposition, or stochastic estimation can be employed. Systematic comparisons of wind-tunnel measurements and LES simulation results are planned

    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. Mots Clés liquide ionique, cellulose, cristallinité, réactivité, dissolution, régénération, non-solvant, purification, prétraitement, zone amorphe.

  6. Stochastic parameterization of moist convection estimated from LES data

    NASA Astrophysics Data System (ADS)

    Dorrestijn, J.; Crommelin, D.; Biello, J. A.; Böing, S.; Siebesma, P.; Jonker, H. J.

    2012-12-01

    We report on the development of a methodology for stochastic parameterization of moist convection in General Circulation Models (GCMs), using the data-driven approach proposed by (1). We use data from convection-resolving Large-Eddy Simulation (LES) to estimate stochastic processes that represent convection. These stochastic processes take the form of Markov chains that are conditioned on the resolved scale state of the atmosphere. They mimic, in a computationally inexpensive manner, the convective behaviour observed in the LES. We explore cases of shallow and deep convection. In the first case we use LES data of shallow cumulus convection (2). The Markov chains switch between different vertical flux profiles of turbulent heat and moisture. We show that our model is able to reproduce the correct variability of the fluxes, i.e. close to the variability that is observed in the LES data. In the second case we use LES data of the development of deep convection (3). Here the Markov chains switch between different cloud types, similar to the multicloud model of Khouider et al. 2010 (4). Each Markov chain represents the cloud type (convective state) on small horizontal domain (in our case, 150 x 150 meter^2). By grouping these small domains in large blocks that match the size of a GCM grid box, the parameterization can be employed for GCM grid boxes of different sizes. The fractions of the various cloud types in these large blocks determine the total convective transport in each block. We show that the the evolution of the cloud fractions is well captured. We also demonstrate that nearest-neighbor coupling of the Markov chains improves the variability of the stochastically generated cloud fractions. Such spatially coupled Markov chains are equivalent to stochastic cellular automata.

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

  9. The CEO's second act.

    PubMed

    Nadler, David A

    2007-01-01

    When a CEO leaves because of performance problems, the company typically recruits someone thought to be better equipped to fix what the departing executive couldn't--or wouldn't. The board places its confidence in the new person because of the present dilemma's similarity to some previous challenge that he or she dealt with successfully. But familiar problems are inevitably succeeded by less familiar ones, for which the specially selected CEO is not quite so qualified. More often than not, the experiences, skills, and temperament that yielded triumph in Act I turn out to be unequal to Act II's difficulties. In fact, the approaches that worked so brilliantly in Act I may be the very opposite of what is needed in Act II. The CEO has four choices: refuse to change, in which case he or she will be replaced; realize that the next act requires new skills and learn them; downsize or circumscribe his or her role to compensate for deficiencies; or line up a successor who is qualified to fill a role to which the incumbent's skills and interests are no longer suited. Hewlett-Packard's Carly Fiorina exemplifies the first alternative; Merrill Lynch's Stanley O'Neal the second; Google's Sergey Brin and Larry Page the third; and Quest Diagnostics' Ken Freeman the fourth. All but the first option are reasonable responses to the challenges presented in the second acts of most CEOs' tenures. And all but the first require a power of observation, a propensity for introspection, and a strain of humility that are rare in the ranks of the very people who need those qualities most. There are four essential steps executives can take to discern that they have entered new territory and to respond accordingly: recognition that their leadership style and approach are no longer working; acceptance of others' advice on why performance is faltering; analysis and understanding of the nature of the Act II shift; and, finally, decision and action.

    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

    Regier, Frank A.

    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.

    The U.S. Army Topographic Engineering Center, concerned about frequency license problems inherent with operating data-ready radios to support differential GPS (DGPS), learned of an experiment program the National Aeronautics and Space Administration (NASA) was sponsoring with its prototype digital satellite - the Advanced Communications Technology Satellite (ACTS). ACTS was designed to evaluate many new, untested technologies for eventual transfer to U.S. telecommunications and related industries. The new technologies promised greater data transmission rates and significantly reduced transmission latency. recognizing these benefits, the Topographic Engineering Center designed a DGPS experiment using an ACTS datalink with baselines of 200 kilometers and longer to learn what positional accuracy was possible with leading-edge satellite telecommunications technology.

    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.

    Neuromuscular mechanisms regulating esophageal bolus transport are well studied. However, detailed data about the relationship between bolus transit and lower esophageal sphincter (LES)-relaxation during conventional motility testing are still lacking. We performed systematic studies in 25 normal subjects, employing a catheter that integrates the two techniques impedancometry and manometry in a single instrument for simultaneous recording and analysis of the relationship between bolus transit and LES relaxation after swallowing saline or yogurt. 195 swallows were analyzed. LES relaxation occurred frequently later than UES relaxation. The mean latency between bolus entry into the esophagus and LES relaxation was 3.6 +0.2 sec. Two types of swallow-induced LES relaxation were observed: (a) LES relaxation preceding bolus transit (46 cases or 24%) and (b) LES relaxation occurring during bolus transit (149 cases or 76%). In the later case, during 114 (76%) cases of this deglutition, the position of the bolus was very close to the LES. During deglutition, LES relaxation seems to be modulated by bolus transit and occurs predominantly upon arrival of the bolus in the distal esophagus.

    RÉSUMÉ Les progrès médicaux et technologiques ont permis d’ac-croître les taux de survie et d’améliorer la qualité de vie des nourrissons, des enfants et des adolescents ayant des maladies chroniques mettant la vie en danger. La planifi-cation préalable des soins inclut le processus relié aux discussions sur les traitements essentiels au maintien de la survie et la détermination des objectifs des soins de longue durée. Les dispensateurs de soins pédiatriques ont l’obligation éthique d’assimiler cet aspect des soins médicaux. Le présent document de principes vise à aider les dispensateurs de soins à discuter de la planification préalable des soins des patients pédiatriques dans diverses situations. La planification préalable des soins exige des communications efficaces afin de clarifier les objectifs des soins et de s’entendre sur les traitements pertinents ou non pour réaliser ces objectifs, y compris les mesures de réanimation et les mesures palliatives.

    The US Naval Observatory has completed the compilation of the ACT Reference Catalog, containing 988,758 stars covering the entire sky. The motivation behind the ACT was to provide accurate proper motions for the majority of the stars in the Tycho Catalogue. To do this, positions from new reductions of the Astrographic Catalogue (AC 2000) were combined with those of the Tycho Catalogue. The large epoch span between the two catalogs yields proper motions about an order of magnitude more accurate than those found in the Tycho Catalogue. The astrometric data contained in the ACT Reference Catalog include positions and proper motions and their corresponding errors. These are on the Hipparcos system (ICRS) for epoch J2000.0. Photometric and variability data from Tycho are included. In addition, cross-references to the Tycho, AC 2000, Bonner Durchmusterung (BD), Cordoba Durchmusterung (CD), Cape Durchmusterung (CPD), Henry Draper (HD), and Hipparcos catalogs are given. The ACT is now available at the international data centers and by contacting the authors via electronic mail.

  6. Transition de phase quantique de type verrouillage-deverrouillage dans les canaux lineaires coherents des phases en rayures dans les doubles puits quantiques sous champ magnetique perpendiculaire

    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

    As one looks into the next generation of transport and delivery trucks and considers future upgrades for bulk plants, one should first buy a crystal ball. If you are like most of us you cannot, with absolute certainty, know what the future will bring. You can rest assured that the capital investments you are now contemplating will probably last long enough to be affected by legislation now pending (or being concocted by someone). There are certain things you can plan for and do to prepare just in case. Rather than simply keeping a dry match on hand, consider these ideas. For starters, keep track of the proposed legislation notices you receive from your local or state councils. These proposed mandates act as a barometer to indicate probable changes (FOOH does a good job at alerting you to some of these). Much of the new legislation evolves in response to environmental incidents. No matter how carefully you plan, a future regulation may mandate a change at your plant. You can prepare without spending large sums of additional money through careful planning.

    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.

  12. Is there a future for electricity futures?

    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?

  13. 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.

  14. 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.

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

    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.

    2015-11-01

    This work focuses on the investigation of various wall modeling strategies for the simulation of high Reynolds number wall-bounded turbulent flows with acceleration and/or deceleration. Our code is based on fourth order finite differences, is momentum conserving, and is energy conserving up to fourth order. We here use a ``channel flow'' set-up, with no slip and wall modeling at the bottom, with slip at the top, and with blowing and/or suction at the top in order to generate the desired acceleration-deceleration profile. Two strategies are investigated and compared. Pressure gradient corrected algebraic models are first considered, and we investigate various local averaging techniques so as to avoid imposing mean profile laws pointwise. RANS sub-layer models are then also considered, where the turbulent viscosity is corrected to account for pressure gradient effects and for resolved LES fluctuations effects. A wall-resolved LES was also performed to provide a reference solution. Research fellow (Ph.D. student) at the F.R.S. - FNRS (Belgium).

  18. 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.

  19. High speed turbulent reacting flows: DNS and LES

    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.

  8. Strategies for comparing LES and experimental data of urban turbulence

    NASA Astrophysics Data System (ADS)

    Hertwig, D.; Nguyen van yen, R.; Patnaik, G.; Leitl, B.

    2012-12-01

    Unsteady flow within and above built environments is an important example of the complex nature of near-surface atmospheric turbulence. Typically, obstacle-resolving micro-scale meteorological models based on the Reynolds-averaged conservation equations are adopted to investigate and predict the mean-states of urban flow phenomena. The rapid advancements in computer capacities, however, fostered the use of time-resolved approaches like large-eddy simulation (LES) for applications on the urban micro-scale. LES has the potential to provide a realistic picture of the spatio-temporal behavior of turbulent flows within and above the urban canopy layer, which cannot be easily achieved with classic in-situ micro-meteorological measurements. The further success of eddy-resolving techniques, however, is coupled to the critical assessment of the model performance in terms of a rigorous validation against suitable reference data. This task is particularly challenging with regard to the time-dependent nature of the problem and the need to verify whether the model predicts turbulence structures in a realistic way. In this study, a hierarchy of validation strategies for urban LES flow fields is formulated and systematically applied. The test case is neutrally stratified turbulent flow in the inner city of Hamburg, Germany. The LES computations were conducted by the U.S. Naval Research Laboratory on the basis of a monotone integrated LES methodology. Reference experiments in terms of single-point, high resolution time-series measurements were carried out in the boundary-layer wind-tunnel facility at the University of Hamburg. The wind-tunnel model was built on a scale of 1:350 and included building structures with a full-scale spatial resolution of 0.5 m. Benchmark parameters for the congruent representation of atmospheric inflow conditions in the physical and the numerical model were obtained from long-term sonic anemometer measurements at a suburban meteorological field site

    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.

  20. A New LES/PDF Method for Computational Modeling of Turbulent Reacting Flows

    NASA Astrophysics Data System (ADS)

    Turkeri, Hasret; Muradoglu, Metin; Pope, Stephen B.

    2013-11-01

    A new LES/PDF method is developed for computational modeling of turbulent reacting flows. The open source package, OpenFOAM, is adopted as the LES solver and combined with the particle-based Monte Carlo method to solve the LES/PDF model equations. The dynamic Smagorinsky model is employed to account for the subgrid-scale motions. The LES solver is first validated for the Sandia Flame D using a steady flamelet method in which the chemical compositions, density and temperature fields are parameterized by the mean mixture fraction and its variance. In this approach, the modeled transport equations for the mean mixture fraction and the square of the mixture fraction are solved and the variance is then computed from its definition. The results are found to be in a good agreement with the experimental data. Then the LES solver is combined with the particle-based Monte Carlo algorithm to form a complete solver for the LES/PDF model equations. The in situ adaptive tabulation (ISAT) algorithm is incorporated into the LES/PDF method for efficient implementation of detailed chemical kinetics. The LES/PDF method is also applied to the Sandia Flame D using the GRI-Mech 3.0 chemical mechanism and the results are compared with the experimental data and the earlier PDF simulations.

    All of the 4000 infants who die daily in India have been bottle fed. Most of these infants die from infections which are typically caused by bottle feeding. Considerable research has shown that human breast milk ideally suits babies' needs. Human breast milk protects infants from several infections and allergies, such that the breastfed infant is 25 times less likely than the bottle fed infant to die due to diarrhea and pneumonia. Comparative studies have even found breastfed babies to have higher IQs than bottle fed ones. Detrimental maternity home practices, adverse social factors, and the unethical and aggressive marketing strategy adopted by the manufacturers of infant milk substitutes and feeding bottles are the major factors responsible for the erosion of the practice of breastfeeding. These factors are discussed. The Infant Milk Substitutes, Feeding Bottles, and Infant Foods Act prohibits the advertisement and promotion of feeding bottles and infant milk substitutes by unethical marketing strategies. Violations of the act are punishable by imprisonment and a heavy fine. The act and the need for its passage are discussed.

    1992-01-01

    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.

    Growth in wind power production has motivated investigation of wind-farm impacts on in situ flow fields and downstream interactions with agriculture and other wind farms. These impacts can be simulated with both large-eddy simulations (LES) and mesoscale wind-farm parameterizations (WFP). The Weather Research and Forecasting (WRF) model offers both approaches. We used the validated generalized actuator disk (GAD) parameterization in WRF-LES to assess WFP performance. A 12-turbine array was simulated using the GAD model and the WFP in WRF. We examined the performance of each scheme in both convective and stable conditions. The GAD model and WFP produced qualitatively similar wind speed deficits and turbulent kinetic energy (TKE) production across the array in both stability regimes, though the magnitudes of velocity deficits and TKE production levels were underestimated and overestimated, respectively. While wake growth slowed in the latter half of the WFP array as expected, wakes did not approach steady state by the end of the array as simulated by the GAD model. A sensitivity test involving the deactivation of explicit TKE production by the WFP resulted in turbulence levels within the array well that were below those produced by the GAD in both stable and unstable conditions. Finally, the WFP overestimated downwind power production deficits in stable conditions because of the lack of wake stabilization in the latter half of the array.

    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

    1995-01-01

    In 1995 the UN celebrated its 50th anniversary, and the Fourth World Conference on Women in Beijing was held. INSTRAW's acting director, Martha Duenas-Loza, gives her overview of INSTRAW's future role and identifies some major issues regarding the advancement of women. INSTRAW is mandated as a UN group to accomplish research on and training of women. Some initial findings are now becoming available. The delay was due to the attention given to pressing problems of health care, nutrition, and education. In the future the international community will not have the option of neglecting women's status issues, which currently are secondary concerns. Some urgent issues are identified as the impact of rapid population growth on the elderly in the world, particularly the majority of elderly women. Migration will have an increasing impact on economic and social infrastructures of all countries. Problems of the elderly must be addressed as individual components within development plans and programs. Other articles in this issue of "INSTRAW News" discuss the situation of elderly women and women migrants. New efforts focus on a new phase of research on women's access to credit. The research aim is to analyze the experiences of current credit mechanisms, to assess the impact on individuals and families, and to consider gender effects. A progress report is available in this issue on gender statistics and a valuation of unpaid work by women. A new module is available for training women in environmental management; a description of this module is available in this issue. The new model is based on prior modules on energy and water, but includes improvements. The future agenda reflects the complexity of problems and solutions today and in the future.

    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.

    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.

    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

  15. Historical trends and human futures.

    O'Neill, Onora

    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.

    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.

    Under the Sunshine Act, pharmaceutical and product industry payments to physicians are reported in a public database. We sought to characterize payments received by pediatricians in the first full year of disclosures in 2014. We used the National Centers for Medicare and Medicaid Services Open Payment files to identify pediatricians who received payments. Payment characteristics were stratified, and descriptive statistical analysis was performed, including mean, median, and ranges of payments. Between January 1, 2014, and December 31, 2014, 35 697 pediatricians received payments amounting to $30 031 960. General pediatricians received the majority of payments (71%). Median payment was $15 (interquartile range = $12-$24), mostly in the form of noncash items and services (84%). Significant diversity was observed in median payments among specialty providers. In conclusion, 42% of US pediatricians received industry payments in 2014. These data provide a foundation for future research regarding the influence of the Sunshine Act on pediatric clinical practices.

    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
