Une fistule recto-vaginale rentrant dans le cadre d'un syndrome de Currarino  

PubMed Central

Le syndrome de Currarino (SC) est défini par une triade rassemblant une malformation ano-rectale, une agénésie sacrée et une tumeur pré-sacrée. Nous rapportons le cas d'une fille de 4 ans et demi ayant été admise en consultation de gastro-entérologie pédiatrique pour constipation avec issue de selle à travers un orifice vulvaire. La radiographie du rachis avait montré une agénésie sacrée. Le fistulo-scanner a mis en évidence une fistule recto-vaginale et l'IRM pelvienne a confirmé l'agénésie sacrée et a retrouvé une méningocèle antérieure. La découverte d'une malformation ano-rectale doit faire chercher une autre anomalie de la triade de Currarino. Cette affection, rare, nécessite une prise en charge médico-chirurgicale assez complexe.

L'alimentation des enfants ayant une d?ficience neurologique  

PubMed Central

La malnutrition, qu’il s’agisse de sous-alimentation ou de suralimentation, est courante chez les enfants ayant une déficience neurologique. Les besoins en énergie sont difficiles à définir au sein de cette population hétérogène. De plus, on manque d’information sur ce qui constitue la croissance normale chez ces enfants. Des facteurs non nutritionnels peuvent influer sur la croissance, mais des facteurs nutritionnels, tels qu’un apport calorique insuffisant, des pertes excessives d’éléments nutritifs et un métabolisme énergétique anormal, contribuent également au retard de croissance de ces enfants. La malnutrition est liée à une importante morbidité, tandis que la réadaptation nutritionnelle améliore l’état de santé global. Le soutien nutritionnel doit faire partie intégrante de la prise en charge des enfants ayant une déficience nutritionnelle et viser non seulement à améliorer l’état nutritionnel, mais également la qualité de vie des patients et de leur famille. Au moment d’envisager une intervention nutritionnelle, il faut tenir compte du dysfonctionnement oromoteur, du reflux gastro-œsophagien et de l’aspiration pulmonaire, et une équipe multidisciplinaire doit se concerter. Il faut repérer rapidement les enfants vulnérables à des troubles nutritionnels et procéder à une évaluation de leur état nutritionnel au moins une fois par année, et plus souvent chez les nourrissons et les jeunes enfants ou chez les enfants qui risquent de souffrir de malnutrition. Il faut optimiser l’apport oral s’il est sécuritaire, mais entreprendre une alimentation entérale chez les enfants ayant un dysfonctionnement oromoteur qui provoque une aspiration marquée ou chez ceux qui sont incapables de maintenir un état nutritionnel suffisant au moyen de l’apport oral. Il faut réserver l’alimentation par sonde nasogastrique aux interventions à court terme, mais si une intervention nutritionnelle prolongée s’impose, il faut envisager la gastrostomie. Il faut réserver les mesures antireflux aux enfants présentant un reflux gastro-œsophagien considérable. Il faut surveiller étroitement la réponse du patient à l’intervention nutritionnelle afin d’éviter une prise de poids excessive après l’amorce de l’alimentation entérale, et privilégier les préparations pédiatriques afin d’éviter les carences en micronutriments.

Caracterisation de la cohesion de l'interface AMF/polymere dans une structure deformable adaptative  

NASA Astrophysics Data System (ADS)

Les structures déformables adaptatives (SDA) sont appelées à jouer un rôle important en aéronautique entre autres. Les alliages à mémoire de forme (AMF) sont un des candidats les plus prometteurs. Beaucoup de travail reste toutefois à faire avant que ces structures rencontrent les exigences élevées reliées à leur intégration dans un contexte aéronautique. Des travaux de recherche ont montré que la résistance à la décohésion de l’interface AMF/polymère peut être un élément limitant dans la performance des SDA. Dans ce travail, l’effet sur la résistance à la décohésion de l’interface AMF/polymère de divers traitements de surface, géométries de fil et types de polymère est évalué. La géométrie du fil est modifiée par une combinaison spécifique de laminage à froid et de recuit postdéformation qui maintient les propriétés de mémoire de forme tout en permettant de réduire l’aire de la section transversale du fil. Le traitement thermomécanique le plus prometteur est proposé. Une nouvelle méthode d’évaluation de la résistance à la décohésion est développée. Plutôt que de tester les fils en arrachement et de mesurer la force maximale, les tests en contraction sont basés sur la capacité des fils d’AMF à se contracter s’ils ont été encastrés dans un état tiré et qu’ils sont chauffés par effet Joule. L’hypothèse qu’on pose est que ces tests sont une meilleure approximation des conditions rencontrées dans une SDA, où les fils se contractent plutôt qu’ils sont arrachés par une force externe à la structure. Bien qu’une décohésion partielle ait été observée pour tous les échantillons, l’aire de la surface où il y a décohésion tait plus grande pour les échantillons avec une pré-déformation plus grande. Le front de décohésion a semblé cesser de progresser après les cycles de chauffage initiaux lorsque la vitesse de chauffage était faible. Un modèle numérique simulant la réponse thermique transitoire du polymère et du fil d’AMF lors d’un chauffage par effet Joule est programmé à l’aide du logiciel ANSYS. Le comportement du modèle est validé avec des résultats expérimentaux où des thermocouples encastrés dans l’échantillon permettent des mesures locales de la température. Les résultats calculés sont en accord avec les résultats expérimentaux d’un point de vue qualitatif, mais accusent des différences significatives d’un point de vue quantitatif. La mesure du champ de déformation à l’interface du fil et du polymère dans une SDA permettrait de développer et valider un modèle numérique prenant en compte l’effet mémoire de forme d’un fil encastré dans une matrice polymère. Dans ce but, une machine de traction miniature permettant l’analyse par microspectrométrie Raman in situ est présentée. Elle a une capacité de 1 kN et un déplacement maximal de 20 mm dans une enveloppe de conception totale de 160 mm de diamètre. La machine est conçue pour que le milieu de l’échantillon soit immobile grâce au fait que le mouvement des deux extrémités soit symétrique. Les résultats montrent que du travail supplémentaire est nécessaire avant de pouvoir encastrer des fils d’AMF dans une structure déformable adaptative. Mots-clés: décohésion, structure active, alliage à mémoire de forme, AMF, tests d’arrachement.

Sur le chaos Lagrangien dans une cuve elliptique  

NASA Astrophysics Data System (ADS)

A viscous fluid is introduced into the annular space between two concentric, confocal ellipses. The inner and outer walls can be displaced along their circumference. A small quantity of fluorescent dye is introduced into the fluid and deformation and mixing are studied for the case of periodic boundary movement. An analytical solution in elliptical coordinates has been previously derived for creeping flow conditions. Poincaré sections for a given set of parameters indicate that counter-rotation leads to a more chaotic behaviour than co-rotation, this result is confirmed experimentally. This geometry can also be used as a heat exchanger. By a suitable choice of the parameters, the heat transfer for steady boundary motion can be increased by more than 50% with respect to the concentric cylinder system. If the inner and outer walls are displaced time-periodically, the heat transfer rate obtained can be more than double the rate obtained between concentric cylinders. Un fluide visqueux est introduit dans une cuve de géométrie elliptique, les parois interne et externe de cette cuve tournent suivant le périmètre de l'ellipse. Une petite quantité de traceur fluorescent est introduite dans le fluide et la déformation de l'élément marqué, lorsque le mouvement des deux parois est périodique, est étudiée. Pour cet écoulement où le nombre de Reynolds est très inférieur à 1 (régime de Stokes) et à partir d'une solution analytique récemmnent obtenue pour le cas stationnaire, des sections de Poincaré ont été tracées pour le cas d'une contra-rotation et d'une co-rotation. Les résultats expérimentaux montrent que, pour un protocole de mélange discontinu approprié, cette géométrie mène vers un mélange chaotique après un petit nombre de périodes. Par ailleurs, il est préférable de faire tourner les ellipses en contra-rotation. Ce résultat, en contradiction avec ceux déjà obtenus dans l'espace annulaire entre cylindres excentrés tournants, est confirmé numériquement par les sections de Poincaré. Enfin, ce système s'avère être un très bon échangeur de chaleur. Quand les parois interne et externe se déplacent par alternance, le transfert thermique entre la paroi et le fluide augmente considérablement. Par rapport au cas cylindrique concentrique, la géométrie elliptique conduit à un accroissement, d'un facteur supérieur à 2, du transfert thermique en régime de Couette.

Fairness and nanotechnology concern.  

PubMed

Research suggests that fairness perceptions matter to people who are asked to evaluate the acceptability of risks or risk management. Two separate national random surveys (n?= 305 and?n?= 529) addressed Americans' concerns about and acceptance of nanotechnology risk management in the context of the degree to which they view scientists and risk managers as fair. The first survey investigated general views about scientists across four proposed dimensions of fairness (distributional, procedural, interpersonal, and informational). The results show that respondents who believe that the outcomes of scientific research tend to result in unequal benefits (distributional fairness) and that the procedures meant to protect the public from scientific research are biased (procedural fairness) were more concerned about nanotechnology. Believing scientists would treat them with respect (interpersonal fairness) and ensure access to information (informational fairness) were not significant predictors of concern. The second study also looked at these four dimensions of fairness but focused on perceptions of risk managers working for government, universities, and major companies. In addition to concern, it also examined acceptance of nanotechnology risk management. Study 2 results were similar to those of study 1 for concern; however, only perceived informational fairness consistently predicted acceptance of nanotechnology risk management. Overall, the study points to the value of considering fairness perceptions in the study of public perceptions of nanotechnology. PMID:21883336

A fair test of the fair innings?  

PubMed

Priority setting in health care under conventional rules of health economic evaluation is based upon the ethos of attempting to maximize post-treatment health gain given available health care resources. In his later years, Alan Williams advocated the "fair innings argument,'' which balances differences in whole lifetime experiences of health with differences in post-treatment outcomes when prioritizing people for health care. This article reports a study that presented respondents with a number of abstract health care decision contexts in an attempt to test the extent to which post-treatment health maximization, the fair innings argument, or, indeed other "decision rules,'' are evident in the respondents' answers. The results indicate that the most commonly observed decision rule differs substantially across health care contexts, and therefore imply that rather than pursue an overarching decision rule, it may be more appropriate to vary the rule according to the particular health care decision context under consideration.

Fair weather atmospheric electricity  

NASA Astrophysics Data System (ADS)

Not long after Franklin's iconic studies, an atmospheric electric field was discovered in "fair weather" regions, well away from thunderstorms. The origin of the fair weather field was sought by Lord Kelvin, through development of electrostatic instrumentation and early data logging techniques, but was ultimately explained through the global circuit model of C.T.R. Wilson. In Wilson's model, charge exchanged by disturbed weather electrifies the ionosphere, and returns via a small vertical current density in fair weather regions. New insights into the relevance of fair weather atmospheric electricity to terrestrial and planetary atmospheres are now emerging. For example, there is a possible role of the global circuit current density in atmospheric processes, such as cloud formation. Beyond natural atmospheric processes, a novel practical application is the use of early atmospheric electrostatic investigations to provide quantitative information on past urban air pollution.

Vehicle underbody fairing  

DOEpatents

A vehicle underbody fairing apparatus for reducing aerodynamic drag caused by a vehicle wheel assembly, by reducing the size of a recirculation zone formed under the vehicle body immediately downstream of the vehicle wheel assembly. The fairing body has a tapered aerodynamic surface that extends from a front end to a rear end of the fairing body with a substantially U-shaped cross-section that tapers in both height and width. Fasteners or other mounting devices secure the fairing body to an underside surface of the vehicle body, so that the front end is immediately downstream of the vehicle wheel assembly and a bottom section of the tapered aerodynamic surface rises towards the underside surface as it extends in a downstream direction.

Tobacco, taxation, and fairness.

The author defends himself against an attack by Smith and Bopp on his views on smoking and taxation. The theory that, on the grounds of equity and/or fairness, smokers should pay via taxation on tobacco for the health care costs of treating smoking-related medical conditions is discussed and shown to be defective. It is argued that the fundamental mistake that Smith and Bopp make is to confuse and conflate the separate issues of whether particular taxes are fair and whether they are justifiable. The conclusion is reached that an excise duty on tobacco is a good tax. It is a non-fair or even an unfair tax but it is justified on grounds other than fairness. PMID:12468659

State Fair Recipes  

NSDL National Science Digital Library

As the summer continues to wane on, one tradition remains intact throughout much of America: the state fair. Usually the state fair is a place for local residents to showcase their agricultural marvels, and for urbanites to experience a bit of the country life, albeit rather briefly and somewhat voyeuristically. While there may be an uneasy alliance between urbanites and rural denizens during these periods, one thing is for sure: they both love the award-winning eats that are often the highlight of such gatherings. One is certain to find certain specialties at every fair, ranging from the famous scones of the Washington State Fair in Puyallup to the roast corn that may be found at just about every state fair. This website brings all of those award-winning recipes together in one place, as visitors can find recipes for such dishes as beef and cheddar puffs, braised lamb shanks, and down home chicken pot pie. Desserts don't get short thrift here either, as visitors can read the recipes for ginger lime pear pie and many others as well. Finally, visitors can read profiles of the various award-winning cooks and find recipes from 2000 to 2004.

This paper addresses an important multi-disciplinary issue of current interest, that is, the implications of technological design for fairness. A visual, graphical methodology centered on the Taylor-Russell diagram is proposed to address this issue. The Taylor-Russell diagram helps to identify and explore ways in which predictions built into designs can pit the interests of different constituencies against one another. The configuration of the design represents a trade-off between the interests of the communities involved. Whether or not the trade-off is appropriate constitutes a problem of fairness or distributive justice. The breadth of this methodology is supported by a diversity of examples analyzed. These include a surveillance system, an automotive safety system, a civic information system, and the international food distribution system. These examples provide models for application of the methodology to the analysis of designs in further areas of concern. Limitations of the methodology are also discussed. While it helps to identify and clarify issues of fairness in technology design, the methodology does not provide a general theory of fairness, nor can it provide fair solutions to such issues without appeal to further principles or concepts.

A polypyrrole membrane has been used as an electrochemical pump. Molecules can be made to diffuse through the membrane only by applying oxidoreduction cycles. The system is very sensitive to the nature of the different species, only the initial doping anion crossing the membrane easily. Une membrane de polypyrrole a été utilisée en tant que pompe électrochimique. Seuls des cycles d'oxydoréduction imposés à la membrane permettent à des molécules de la traverser. Le système apparaît comme très sensible à la nature des molécules à faire diffuser et seul l'anion initialement dopant peut facilement traverser la membrane.

Bargaining and fairness.  

PubMed

The idea that human morality might be the product of evolution is not popular. The reason is partly that the moral principles that actually govern our day-to-day behavior have been idealized in a way that makes a natural origin seem impossible. This paper puts the case for a more down-to-earth assessment of human morality by arguing that the evolution of our sense of fairness can be traced to the practicalities of food-sharing. When animals share food, they can be seen as enjoying the fruits of an implicit bargain to ensure each other against hunger. The implications of this observation are explored using the tools of game theory. The arguments lead to a structure for fair bargains that closely resembles the structure proposed by John Rawls, the leading moral philosopher of the last century. PMID:25024181

Fair trade international surrogacy.  

PubMed

Since the development of assisted reproductive technologies, infertile individuals have crossed borders to obtain treatments unavailable or unaffordable in their own country. Recent media coverage has focused on the outsourcing of surrogacy to developing countries, where the cost for surrogacy is significantly less than the equivalent cost in a more developed country. This paper discusses the ethical arguments against international surrogacy. The major opposition viewpoints can be broadly divided into arguments about welfare, commodification and exploitation. It is argued that the only valid objection to international surrogacy is that surrogate mothers may be exploited by being given too little compensation. However, the possibility of exploitation is a weak argument for prohibition, as employment alternatives for potential surrogate mothers may be more exploitative or more harmful than surrogacy. It is concluded that international surrogacy must be regulated, and the proposed regulatory mechanism is termed Fair Trade Surrogacy. The guidelines of Fair Trade Surrogacy focus on minimizing potential harms to all parties and ensuring fair compensation for surrogate mothers. PMID:19508290

PROTON MICROSCOPY AT FAIR  

SciTech Connect

Proton radiography was invented in the 1990's at Los Alamos National Laboratory (LANL) as a diagnostic to study dynamic material properties under extreme pressures, strain and strain rate. Since this time hundreds of dynamic proton radiography experiments have been performed at LANL and a facility has been commissioned at the Institute for Theoretical and Experimental Physics (ITEP) in Russia for similar applications in dynamic material studies. Recently an international effort has investigated a new proton radiography capability for the study of dynamic material properties at the Facility for Anti-proton and Ion Research (FAIR) located in Darmstadt, Germany. This new Proton microscope for FAIR(PRIOR) will provide radiographic imaging of dynamic systems with unprecedented spatial, temporal and density resolution, resulting in a window for understanding dynamic material properties at new length scales. It is also proposed to install the PRIOR system at the GSI Helmholtzzentrum fuer Schwerionenforschung before installation at FAIR for dynamic experiments with different drivers including high explosives, pulsed power and lasers. The design of the proton microscope and expected radiographic performance is presented.

Astronomy Science Fair Projects  

NASA Astrophysics Data System (ADS)

``Extrasolar Planet Transit", ``Lightcurve of a Variable Star", and ``Retrograde Motion of Mars" are some of the titles of high school students' projects entered in the Hawaii State Science Fair. TOPS (Toward Other Planetary Systems) teachers who participated in the University of Hawaii Institute for Astronomy summer outreach program under the direction of professor Karen J. Meech mentored their students. After attending the 3-week National Science Foundation Institute for several summers since 1999, these teachers in the summer of 2003 were trained to do observing plans to obtain images from telescopes, use image processing software MIRA for photometry, and produce light curves of variable stars and extrasolar planet transits. Others used the software ``Astrometrica" to do astrometry of Kuiper Belt Objects. Using Compaq laptop computers on long term loan, our teachers mentored students for astronomy projects during the 2003-2004 school year. These students made observing plans for images from the 31inch Lowell Telescope in Arizona and/or from the 2.2m University of Hawaii Telescope at Mauna Kea Observatory. Learning about filters, exposure time, magnitude, frequency of taking CCD images, and ephemeris required many iterations between students, teachers, and astronomers and graduate students who were assisting. Poor weather conditions and other frustrations exposed the students to the realities of research. However, they were rewarded with projects that impressed the judges and that will be described.

La miliaire h?patique: une pr?sentation ?chographique rare de la tuberculose h?patique d?couverte chez un adolescent immuno-comp?tent  

PubMed Central

Ce cas clinique rapporte un cas de tuberculose hépatique de présentation échographique exceptionnelle. Nous avons réalisé l’échographie abdominale d'un adolescent de 12 ans, immuno-compétent, sans notion de contage tuberculeux, se plaignant de douleur abdominale chronique évoluant depuis 8 mois associée à des signes frustres d‘imprégnation tuberculeuse. L'examen échographique a été réalisé à l'aide d'un appareil écho-doppler de marque Logic 400 de la firme General Electric. L’échographie abdominale a mis en évidence, une hépatomégalie comportant de multiples micro-abcès hypoéchogènes homogènes, mesurant entre 3 et 4 mm de diamètre et disséminés dans tout le parenchyme hépatique donnant l'aspect de miliaire. Une ascite de moyenne abondance localisée dans le pelvis a été objectivée. Il n'y avait pas d'adénopathies profondes ni de nodules péritonéaux. La ponction biopsie hépatique sous guidage échographique a permis de faire le diagnostic de tuberculose hépatique à l'histologie et à la bactériologie. Le patient a été mis sous traitement spécifique avec une surveillance échographique mensuelle. La disparition des micro-abcès et le tarissement de l'ascite ont été obtenus au bout du 4ème mois du traitement. Celle de l'hépatomégalie est survenue un mois plus tard. L’échographie joue un rôle très important dans la détection précoce de la tuberculose hépatique, son diagnostic précis et la surveillance du traitement. Lors de sa réalisation dans un contexte de douleur abdominale chronique chez l'enfant, l’échographiste devrait évoquer le diagnostic de tuberculose hépatique devant une hépatomégalie multi-micro-abcédée, même chez l'enfant immuno-compétent.

Nuclear Astrophysics at FAIR  

NASA Astrophysics Data System (ADS)

An overview about the future international Facility for Antiproton and Ion Research -FAIR- is given, with especial emphasis on the astrophysical aspects of the NUSTAR (NUclear StrucTure, Astrophysics and Reactions) project. Many types of astrophysically relevant experiments will be performed at NUSTAR. A common tool in all of them will be the large acceptance superconducting in-flight fragment separator (Super-FRS). Rare isotopes of all elements up to Uranium will be produced and spatially separated, thus allowing for the study of very short-lived nuclei. At the low energy branch of the SuperFRS the DESPEC-setup will allow for precise ?-decay measurements, including neutron emission probabilities, and for the study of the nuclear structure of very exotic species. High precision Penning trap mass measurements will be carried out with the MATS setup installed at the low-energy branch. Large scale mass measurements will be performed using a complex of storage and cooler rings, the NESR and the CR. In summary, a vast amount of new data far off stability will become available. This will be particularly interesting for the study of explosive nucleosynthesis events, like the rapid neutron capture and the rapid proton capture processes. At the high-energy branch of the SuperFRS, the R3B setup will provide access to a large variety of kinematically complete measurements at relativistic energies, such as heavy ion induced electromagnetic excitation, knockout and breakup reactions or light-ion (in)elastic scattering in inverse kinematics. This will enable e.g. to study Gamow-Teller strengths or to determine astrophysical S-factors on exotic nuclei.

Fair use versus fair return: copyright legislation and its consequences.  

PubMed

The purpose of this article is to examine the ramifications of legislative recognition of the concept of fair use in the Copyright Act of 1976. The fair use concept, while of small consequence in its normative origins, has turned out to be the foundation of the most perplexing and divisive issues in the new legislative guidelines governing copyright. Legislative recognition of the concept of fair use, coupled with enormous growth of a new technology--extending from xerography to on-line database systems--creates de facto exemptions to both the intent and content of new copyright guidelines. The issue is not one of limiting use or suppressing information, but of mechanisms for safeguarding the rights of copyright holders, be they authors or publishers, and insuring the free flow of information by providing a proper return on both intellectual creativity and capital expenditures. The authors argue that the elimination, or at least curtailment of fair use doctrine, coupled with an increase in technological approaches to reporting of secondary use of copyrighted material, will benefit all sections of the knowledge industry. Authors will receive proper royalties on use; publishers will be able to sell more books and journals at lower prices; and librarians will be liberated from extensive chores such as monitoring usage or determining fee schedules and transferences. The issue is one of fair return--an issue obscured and ultimately subverted by fair use. PMID:10265308

Restauration adaptative des contours par une approche inspiree de la prediction des performances  

NASA Astrophysics Data System (ADS)

En teledetection, les cartes de contours peuvent servir, entre autres choses, a la restitution geometrique, a la recherche d'elements lineaires, ainsi qu'a la segmentation. La creation de ces cartes est faite relativement tot dans la chaine de traitements d'une image. Pour assurer la qualite des operations subsequentes, il faut veiller a obtenir une carte de contours precise. Notre problematique est de savoir s'il est possible de diminuer la perte de temps liee au choix d'algorithme et de parametre en corrigeant automatiquement la carte de contours. Nous concentrerons donc nos efforts sur le developpement d'une methode de detection/restauration de contours adaptative. Notre methode s'inspire d'une technique de prediction des performances d'algorithmes de bas niveau. Elle consiste a integrer un traitement par reseau de neurones a une methode " classique " de detection de contours. Plus precisement, nous proposons de combiner la carte de performances avec la carte de gradient pour permettre des decisions plus exactes. La presente etude a permis de developper un logiciel comprenant un reseau de neurones entraine pour predire la presence de contours. Ce reseau de neurones permet d'ameliorer les decisions de detecteurs de contours, en reduisant le nombre de pixels de fausses alarmes et de contours manques. La premiere etape de ce travail consiste en une methode d'evaluation de performance pour les cartes de contours. Une fois ce choix effectue, il devient possible de comparer les cartes entre elles. Il est donc plus aise de determiner, pour chaque image, la meilleure detection de contours. La revue de la litterature realisee simultanement a permis de faire un choix d'un groupe d'indicateurs prometteurs pour la restauration de contours. Ces derniers ont servi a la calibration et a l'entrainement d'un reseau de neurones pour modeliser les contours. Par la suite, l'information fournie par ce reseau a ete combinee par multiplication arithmetique avec les cartes d'amplitudes de detecteurs " classiques " afin de fournir de nouvelles cartes d'amplitude du gradient. Le seuillage de ces contours donne des cartes de contours " optimisees ". Sur les images aeroportees du jeu de donnees South Florida, la mediane des mesures-F de la pour l'algorithme de Sobel passe de 51,3 % avant la fusion a 56,4 % apres. La mediane des mesures-F pour l'algorithme de Kirsch ameliore est de 56,3 % et celle de Frei-Chen ameliore est de 56,3 %. Pour l'algorithme de Sobel avec seuillage adaptatif, la mesure-F mediane est de 52,3 % avant fusion et de 57,2 % apres fusion. En guise de comparaison, la mesure-F mediane pour le detecteur de Moon, mathematiquement optimal pour contours de type " rampe ", est de 53,3 % et celle de l'algorithme de Canny, est de 61,1 %. L'applicabilite de notre algorithme se limite aux images qui, apres filtrage, ont un rapport signal sur bruit superieur ou egal a 20. Sur les photos au sol du jeu de donnees de South Florida, les resultats sont comparables a ceux obtenus sur les images aeroportees. Par contre, sur le jeu de donnees de Berkeley, les resultats n'ont pas ete concluants. Sur une imagette IKONOS du campus de l'Universite de Sherbrooke, pour l'algorithme de Sobel, la mesure-F est de 45,7 % +/-0,9 % avant la fusion et de 50,8 % apres. Sur une imagette IKONOS de l'Agence Spatiale Canadienne, pour l'algorithme de Sobel avec seuillage adaptatif, la mesure-F est de 35,4 % +/-0,9 % avant la fusion et de 42,2 % apres. Sur cette meme image, l'algorithme de Argyle (Canny sans post-traitement) a une mesure-F de 35,1 % +/-0,9 % avant fusion et de 39,5 % apres. Nos travaux ont permis d'ameliorer la banque d'indicateurs de Chalmond, rendant possible le pretraitement avant le seuillage de la carte de gradient. A chaque etape, nous proposons un choix de parametres permettant d'utiliser efficacement la methode proposee. Les contours corriges sont plus fins, plus complets et mieux localises que les contours originaux. Une etude de sensibilite a ete effectuee et permet de mieux comprendre la contributio

It will be used to produce, inter alia, high intensity secondary beams of antiprotons and short-lived radioactive nuclei. A subsequent suite of cooler and storage rings will deliver heavy ion and antiproton beams of unprecedented quality. Large experiments are presently being designed by the NUSTAR, PANDA, PAX, CBM, SPARC, FLAIR, HEDgeHOB and BIOMAT collaborations.

Une maladie immunoprolif?rative de l'intestin gr?le r?v?l?e par une invagination intestinale aigue: ? propos d'un cas  

PubMed Central

La maladie immunoproliférative de l'intestin grêle IPSID est un lymphome rare qui se développé à partir du système lymphoïde associé aux muqueuses au niveau de l'intestin grêle. Sa révélation par une invagination intestinale aigue est exceptionnelle et n'a jamais été rapporté dans la littérature auparavant. Nous rapportons le cas d'un patient de 65ans, admis aux urgences dans un tableau d'invagination intestinale aigue. Le scanner abdominal a mis en évidence masse grêlique à paroi concentrique avec incarcération du segment mésentérique au sein de la lésion fortement évocatrice d'une invagination intestinale. Le patient a été opéré et a bénéficié d'une résection iléale emportant le boudin d'invagination. L'examen histologique de la masse a été en faveur d'une maladie des chaines alpha transformée en un lymphome B diffus à grandes cellules. Les auteurs rapportent un cas rare d'une IPSID révélée par une invagination intestinale aigue et à travers cette observation, mettent en relief les principaux aspects cliniques, histologiques, thérapeutiques de cette entité avec une revue de la littérature.

Towards Polarized Antiprotons at FAIR  

SciTech Connect

Understanding the interplay of the nuclear interaction with polarized protons and the electromagnetic interaction with polarized electrons in polarized atoms is crucial to progress towards the PAX goal to eventually produce stored polarized antiproton beams at FAIR. Presently, there exist two competing theoretical scenarios: one with substantial spin filtering of (anti)protons by atomic electrons, and a second one suggesting a self-cancellation of the electron contribution to spin filtering. After a brief review of the PAX physics case for polarized antiprotons at FAIR, a detailed discussion of future investigations, including spin-filtering experiments at COSY-Juelich and at the AD of CERN is presented.

Résumé Question Dans de nombreuses communautés, on continue à voir survenir des infestations de poux de tête. Certains enfants ont besoin de multiples traitements avant que les poux soient éradiqués. Quels sont les traitements actuellement recommandés pour se débarrasser des poux de tête? Réponse Les infestations de poux de tête (Pediculus humanus capitis) sont fréquentes, surtout chez les enfants d’âge scolaire. Pour minimiser la résistance des poux, l’utilisation des insecticides et la stigmatisation sociale, on devrait limiter le diagnostic et le traitement à ceux qui ont des poux vivants sur le cuir chevelu. Les options de prise en charge prennent surtout la forme de thérapies topiques ou de l’enlèvement physique. Il y a peu d’études importantes qui comparent l’efficacité de ces traitements. Si on utilise des insecticides topiques, il faut répéter le traitement environ 7 jours après et si on a recours au peigne fin sur cheveux mouillés, il faut le faire aux 2 à 3 jours pendant 2 semaines. Les tendances dans la résistance des poux varient grandement selon la région et la résistance est maintenant la cause la plus fréquente de l’échec du traitement.

Evisc?ration transanale de l'intestin gr?le chez l'enfant secondaire ? une contusion de l'abdomen: ? propos d'un cas  

PubMed Central

L’éviscération transanale de l'intestin grêle au cours d'un traumatisme fermé de l'abdomen est une situation exceptionnelle. Nous rapportons le cas d'une fille de 7 ans, reçue pour un état de choc hémorragique avec une éviscération transanale de l'intestin grêle suite à une contusion de l'abdomen. Ce tableau clinique est survenu au décours d'un accident de la circulation. La laparotomie exploratrice permettait de découvrir une plaie longitudinale de la face antérieure du rectum, située au dessus de la réflexion péritonéale, à travers laquelle passaient les anses grêles. Une suture de la plaie rectale associée à une iléostomie double après résection du grêle éviscéré et un à drainage du cul-de-sac de Douglas ont été réalisés. L'enfant est décédé en postopératoire précoce. A travers cette observation, les auteurs se proposent de revoir les cas précédemment décrits et de discuter les options thérapeutiques.

L'objectif de notre travail est la conception d'une nouvelle génération d'implants intersomatiques qui s'adapte parfaitement à la géométrie des plateaux vertébraux en se déformant. Pour cela, nous avons utilisé une nouvelle démarche qui consiste à simuler entièrement le procédé de fabrication en l'occurrence l'emboutissage, Cette simulation, en concervant l'historique des sollicitations exercées sur le matériau lors de sa mise en œuvre permet de valider très précisément sa résistance mécanique en fin de cycle. Au cours de cette étude, nous avons mené en parallèle deux analyses dites “ coopératives ” : l'une fondée sur un modèle phénoménologique de type HILL et l'autre sur un modèle multi-échelles prenant en compte des phénomènes plus physiques afin d'acquérir une bonne connaissance du comportement du matériau lors de la déformation. C'est pour sa bonne résistance, sa biocompatibilité et ses propriétés radiologiques que nous avons choisi le T40 (titane pur) comme matériau.

Children develop a veil of fairness.  

PubMed

Previous research suggests that children develop an increasing concern with fairness over the course of development. Research with adults suggests that the concern with fairness has at least 2 distinct components: a desire to be fair and a desire to signal to others that they are fair. We explore whether children's developing concern with behaving fairly toward others may in part reflect a developing concern with appearing fair to others. In Experiments 1 and 2, most 6- to 8-year-old children behaved fairly toward others when an experimenter was aware of their choices; fewer children opted to behave fairly, however, when they could be unfair to others yet appear fair to the experimenter. In Experiment 3, we explored the development of this concern with appearing fair by using a wider age range (6- to 11-year-olds) and a different method. In this experiment, children chose how to assign a good or bad prize to themselves and another participant by either unilaterally deciding who would get each prize or using a fair procedure--flipping a coin in private. Older children were much more likely to flip the coin than younger children, yet were just as likely as younger children to assign themselves the good prize by reporting winning the coin flip more than chance would dictate. Overall, the results of these experiments suggest that as children grow older they become increasingly concerned with appearing fair to others, which may explain some of their increased tendency to behave fairly.

The FairRoot framework  

NASA Astrophysics Data System (ADS)

The FairRoot framework is an object oriented simulation, reconstruction and data analysis framework based on ROOT. It includes core services for detector simulation and offline analysis. The framework delivers base classes which enable the users to easily construct their experimental setup in a fast and convenient way. By using the Virtual Monte Carlo concept it is possible to perform the simulations using either Geant3 or Geant4 without changing the user code or the geometry description. Using and extending the task mechanism of ROOT it is possible to implement complex analysis tasks in a convenient way. Moreover, using the FairCuda interface of the framework it is possible to run some of these tasks also on GPU. Data IO, as well as parameter handling and data base connections are also handled by the framework. Since some of the experiments will not have an experimental setup with a conventional trigger system, the framework can handle also free flowing input streams of detector data. For this mode of operation the framework provides classes to create the needed time sorted input streams of detector data out of the event based simulation data. There are also tools to do radiation studies and to visualize the simulated data. A CMake-CDash based building and monitoring system is also part of the FairRoot services which helps to build and test the framework on many different platforms in an automatic way, including also Continuous Integration.

Développement expérimental d'une ligne PIXE-XRF pour les matériaux du patrimoine

Nous avons développé une nouvelle ligne expérimentale sur l'accélérateur de particules du Centre de recherche et de restauration des musées de France, permettant de s'affranchir de ces deux limitations en recourant à une variante de la fluorescence des rayons X, dénommée PIXE-XRF (XRF pour X-Ray Fluorescence).

Atmospheric electricity is one of the oldest experimental topics in atmospheric science. The fair weather aspects, although having less dramatic effects than thunderstorm electrification, link the microscale behaviour of ion clusters to currents flowing on the global scale. This talk will include a survey of some past measurements and measurement methods, as atmospheric electrical data from a variety of sites and eras are now being used to understand changes in atmospheric composition. Potential Gradient data was the original source of information on the global atmospheric electrical circuit, and similar measurements can now be used to reconstruct past air pollution concentrations, and black carbon loading.

Calculating fairness. [Estimating fair return on equity for public utilities  

SciTech Connect

Despite the recent restructuring, unbundling, competition, and incentive regulation that has complicated the utility business, estimating the fair rate of return on equity (ROE) remains an important part of public utility base rate cases. For the past two decades, the two most popular methods that regulatory commissions have used for estimating the cost of equity capital for regulated utilities have been the dividend discount method (known as the Discounted Cash Flow model of DCF) and the Capital Asset Pricing Model (or CAPM). Both models use common stock price behavior to draw inferences about the cost of equity. The DCF combines a stock's dividend yield and its predicted dividend growth rate. The CAPM relates changes in a stock's price to changes in the overall market for security prices. These methods have come into question, however, as utilities have increasingly diversified into unregulated activities. When a utility's regulated activities account for 95 to 99 percent of its revenues, there is little practical need to question that its company-specific cost-of-equity capital is overwhelmingly dominated by its regulated activities. But as this percentage continues to decrease, a company's specific cost of equity, as calculated by the DCF or CAPM, is influenced to a larger degree by its unregulated subsidiaries. Two general remedies are available to resolve the problem of setting the fair ROE when the company has substantial holdings in unregulated subsidiaries. One is to abandon (either partially or fully) the practice of using company-specific market information and use a proxy group of comparable utilities instead. The other is to continue using company-specific data, but to adjust the resulting estimates to account for the utility's diversification activity.

Pseudoxanthome ?lastique g?n?ralis? et ?volutif chez une m?lanoderme  

PubMed Central

Le pseudoxanthome élastique (PXE) est une maladie héréditaire du tissu élastique affectant principalement la peau, les yeux et les artères. Nous rapportons une forme évolutive compliquée pour souligner la nécessité de la précocité du diagnostic et du suivi, de l'approche multidisciplinaire et la prise en charge des complications. Une femme de 51 ans, a consulté pour des nappes fripées de papules typiquement en « peau de chagrin » associées à une baisse de l'acuité visuelle, des stries angioïdes compliquées de néovaisseaux choroïdiens aux deux yeux. Les lésions cutanées étaient disséminées à tout le corps mais prédominaient aux plis et les régions adjacentes. Cette forme généralisée et compliquée serait due au retard au diagnostic et à la consultation, habituelle dans notre pays. Les atteintes extra cutanées font toute la gravité de cette maladie qui nécessite une surveillance à vie. Les diagnostics différentiels se font avec la peau citréine, la papulose cervicale fibro-élastique et les PXE exogènes. Aucun traitement spécifique n'est disponible à ce jour. Le PXE nécessite une approche multidisciplinaire pour un conseil génétique et pour sa prise en charge globale et précoce.

L'artérite de Takayasu ou maladie de Takayasu (MT) et la polyarthrite rhumatoïde (PR) et sont deux maladies inflammatoires chroniques et leur association a été rapportée dans la littérature à travers quelques observations de cas sporadiques. Nous rapportons une nouvelle observation d'une telle association. Une patiente âgée de 44 ans, diagnostiquée avec une polyarthrite rhumatoïde à facteur rhumatoïde positif, qui a développé des céphalées avec des vertiges de caractère permanent. L'examen révélait un pouls radial et huméral abolis à droite, un souffle carotidien bilatéral et une tension artérielle imprenable à droite. L'artériographie a confirmé la présence d'une atteinte de l'arc aortique type MT. Le diagnostic d'une maladie de Takayasu associée à une polyarthrite rhumatoïde était retenu. La patiente était traitée par une corticothérapie (prednisone à la dose de 0,5 mg/kg par jour) et un traitement de fond par Méthotrexate avec une bonne réponse initiale. A travers notre observation et une revue de la littérature, les caractéristiques épidémiologiques, étiopathogéniques, cliniques, thérapeutiques et évolutives de cette association seront discutées.

Elementary school teachers and successful science fairs  

NASA Astrophysics Data System (ADS)

The purpose of this research was to examine the knowledge, skills and attitudes of elementary school teachers who have led their students to successful experiences in science fairs. Six research questions guided the study: (1) What knowledge, skills and attitudes do the five selected elementary school teachers draw upon to enable their students to have a successful science fair experience? (2) How do the five selected elementary school teachers enable their students to have a successful science fair experience? (3) Why are the five selected elementary school teachers capable of enabling their students to have a successful science fair experience? (4) How do the knowledge, skills and attitudes of the five selected elementary school teachers compare to the knowledge, skills and attitudes that the National Science Education Standards (National Research Council, 1996) recommend for science teachers? (5) What are the commonalities in the knowledge, skills and attitudes among the five selected elementary school teachers who enable their students to have a successful science fair experience? (6) What are the differences in the knowledge, skills and attitudes among the five selected elementary school teachers who enable their students to have a successful science fair experience? A qualitative multiple-case research design was used to focus on five elementary school teachers who have a history of leading their students to successful experiences in science fairs. Data sources included classroom observations, formal and informal interviews, focus groups, science fair visitations and perusal of documents related to the teachers' science fair preparation of their students. In addition, questionnaires were given to the teachers and their students assessing their views about science and science fairs. A cross-case analysis revealed that the teachers had become knowledgeable about science fairs and science by non-traditional means including attending staff development workshops, traveling and reading about science and science fairs. Their practice matched well with the National Science Education Standards (National Research Council, 1996). All of the teachers displayed positive attitudes toward science and science fairs. There appeared to be a relationship between completing a science fair project at school and very positive attitudes toward science fairs and science. The five teachers had more commonalities than differences in their knowledge base, their skills and their attitudes.

The PANDA Experiment at FAIR  

NASA Astrophysics Data System (ADS)

The PANDA experiment (Pbar ANnihilations at DArmstadt) is a next generation hadron physics detector under design for the Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. It will be using cooled antiproton beams with an energy between 1.5 GeV and 15 GeV interacting with various internal targets. The experiment is focusing on hadron spectroscopy, in particular the search for exotic states in the charmonium region, on the interaction of charm hadrons with the nuclear medium and on double-hypernuclei. With physics requiring precise partial wave analysis the experiment has almost 4? acceptance, a solenoid magnet for high pT tracks and a dipole magnet for the forward part of reaction products. A silicon vertex detector surrounds the interaction point. In both spectrometer parts tracking, charged particle identification, electromagnetic calorimetry and muon identification are available. The experiment is being designed to fully exploit the extraordinary physics potential arising from the availability of high-intensity, cooled antiproton beams. Significant progress beyond the present understanding of the field is expected thanks to improvements in statistics and precision of the data.

Fair share on high performance computing systems : what does fair really mean?  

SciTech Connect

We report on a performance evaluation of a Fair Share system at the ASCI Blue Mountain supercomputer cluster. We study the impacts of share allocation under Fair Share on wait times and expansion factor. We also measure the Service Ratio, a typical figure of merit for Fair Share systems, with respect to a number of job parameters. We conclude that Fair Share does little to alter important performance metrics such as expansion factor. This leads to the question of what Fair Share means on cluster machines. The essential difference between Fair Share on a uni-processor and a cluster is that the workload on a cluster is not fungible in space or time. We find that cluster machines must be highly utilized and support checkpointing in order for Fair Share to function more closely to the spirit in which it was originally developed.

Résumé Objectif Mettre à jour les lignes directrices canadiennes de 2006 sur les soins primaires aux adultes ayant une déficience développementale (DD) et présenter des recommandations pratiques fondées sur les connaissances actuelles pour traiter des problèmes de santé particuliers chez des adultes ayant une DD. Qualité des preuves Des professionnels de la santé expérimentés participant à un colloque et un groupe de travail subséquent ont discuté et convenu des révisions aux lignes directrices de 2006 en se fondant sur une recherche documentaire exhaustive, la rétroaction obtenue des utilisateurs du guide de pratique et les expériences cliniques personnelles. La plupart des preuves disponibles dans ce domaine viennent de l’opinion d’experts ou de déclarations consensuelles publiées (niveau III). Message principal Les adultes ayant une DD ont des problèmes de santé complexes, dont plusieurs diffèrent de ceux de la population en général. De bons soins primaires permettent d’identifier les problèmes de santé particuliers dont souffrent les adultes ayant une DD pour améliorer leur qualité de vie et leur accès aux soins de santé et prévenir la morbidité et le décès prématuré. Ces lignes directrices résument les problèmes de santé générale, physique, comportementale et mentale des adultes ayant une DD que devraient connaître les professionnels des soins primaires et présentent des recommandations pour le dépistage et la prise en charge en se basant sur les connaissances actuelles que les cliniciens peuvent mettre en pratique. En raison de l’interaction des facteurs biologiques, psychoaffectifs et sociaux qui contribuent à la santé et au bien-être des adultes ayant une DD, ces lignes directrices insistent sur la participation des aidants, l’adaptation des interventions, au besoin, et la consultation auprès de divers professionnels de la santé quand ils sont accessibles. Elles mettent aussi en évidence la nature éthique des soins. Les lignes directrices sont formulées dans le contexte d’un cadre éthique qui tient compte des questions comme le consentement éclairé et l’évaluation des bienfaits pour la santé par rapport aux risques de préjudice. Conclusion La mise en œuvre des lignes directrices proposées ici améliorerait la santé des adultes ayant une DD et minimiserait les disparités sur les plans de la santé et des soins de santé entre les adultes ayant une DD et la population en général.

Alors qu'elle est actuellement oubliée dans les pays développés, la syphilis congénitale se voit encore chez nous faute du dépistage anténatal. Ses formes cliniques sont polymorphes et orientent à tord vers d'autres pathologies surtout en période néonatale. Le diagnostic n'est donc pas toujours facile. La révélation d'une syphilis congénitale par une fracture spontanée est exceptionnellement décrite. Nous rapportons dans ce travail le cas d'un nourrisson de 2 mois ramené en consultation pour limitation douloureuse des mouvements du bras droit. Le diagnostic est évoqué sur les données radiologiques et confirmé par la sérologie syphilitique. Le traitement a reposé essentiellement sur l'administration de la pénicilline G avec une bonne évolution clinique.

Fair Model Checking with Process Counter Abstraction  

NASA Astrophysics Data System (ADS)

Parameterized systems are characterized by the presence of a large (or even unbounded) number of behaviorally similar processes, and they often appear in distributed/concurrent systems. A common state space abstraction for checking parameterized systems involves not keeping track of process identifiers by grouping behaviorally similar processes. Such an abstraction, while useful, conflicts with the notion of fairness. Because process identifiers are lost in the abstraction, it is difficult to ensure fairness (in terms of progress in executions) among the processes. In this work, we study the problem of fair model checking with process counter abstraction. Even without maintaining the process identifiers, our on-the-fly checking algorithm enforces fairness by keeping track of the local states from where actions are enabled / executed within an execution trace. We enhance our home-grown PAT model checker with the technique and show its usability via the automated verification of several real-life protocols.

Fairness emergence from zero-intelligence agents  

NASA Astrophysics Data System (ADS)

Fairness plays a key role in explaining the emergence and maintenance of cooperation. Opponent-oriented social utility models were often proposed to explain the origins of fairness preferences in which agents take into account not only their own outcomes but are also concerned with the outcomes of their opponents. Here, we propose a payoff-oriented mechanism in which agents update their beliefs only based on the payoff signals of the previous ultimatum game, regardless of the behaviors and outcomes of the opponents themselves. Employing adaptive ultimatum game, we show that (1) fairness behaviors can emerge out even under such minimalist assumptions, provided that agents are capable of responding to their payoff signals, (2) the average game payoff per agent per round decreases with the increasing discrepancy rate between the average giving rate and the average asking rate, and (3) the belief update process will lead to 50%-50% fair split provided that there is no mutation in the evolutionary dynamics.

Brulure par Foudre. A Propos d'une Observation  

PubMed Central

Summary Aussi loin que l’on remonte dans la littérature, on retrouve des récits relatant des accidents consécutifs à la fulguration chez l’homme. La foudre était alors associée à la colère des dieux ou à la notion de châtiment. La fulguration correspond à un transfert d’énergie entre un cumulonimbus de charge négative et un objet de charge positive se trouvant au niveau du sol. Les lésions déterminées sont à la fois thermiques et électrothermiques. Bien que l’arrêt cardiorespiratoire soit une cause bien documentée de décès, la plupart des cas rapportés dans la littérature décrivent un éventail très disparate des séquelles qui surviennent suite à cet accident. Les Auteurs rapportent le cas d’un patient atteint par la foudre en insistant particulièrement sur les complications neurologiques qui sont survenues en cours d’évolution. Se basant sur cette observation et sur une revue de la littérature, les Auteurs soulignent que le pronostic des patients atteints par la foudre est plus favorable que généralement rapporté.

Incorporating Fairness into Game Theory and Economics  

Microsoft Academic Search

People like to help those who are helping them and to hurt those who are hurting them. Outcomes rejecting such motivations are called fairness equilibria. Outcomes are mutual-max when each person maximizes the other's material payoffs, and mutual-min when each person minimizes the other's payoffs. It is shown that every mutual-max or mutual-min Nash equilibrium is a fairness equilibrium. If

Software Development Infrastructure for the FAIR Experiments  

NASA Astrophysics Data System (ADS)

The proposed project FAIR (Facility for Anti-proton and Ion Research) is an international accelerator facility of the next generation. It builds on top of the experience and technological developments already made at the existing GSI facility, and incorporate new technological concepts. The four scientific pillars of FAIR are NUSTAR (nuclear structure and astrophysics), PANDA (QCD studies with cooled beams of anti-protons), CBM (physics of hadronic matter at highest baryon densities), and APPA (atomic physics, plasma physics, and applications). The FairRoot framework used by all of the big FAIR experiments as a base for their own specific developments, provides basic functionality like IO, geometry handling etc. The challenge is to support all the different experiments with their heterogeneous requirements. Due to the limited manpower, one of the first design decisions was to (re)use as much as possible already available and tested software and to focus on the development of the framework. Beside the framework itself, the FairRoot core team also provides some software development tools. We will describe the complete set of tools in this article. The Makefiles for all projects are generated using CMake. For software testing and the corresponding quality assurance, we use CTest to generate the results and CDash as web front end. The tools are completed by subversion as source code repository and trac as tool for the complete source code management. This set of tools allows us to offer the full functionality we have for FairRoot also to the experiments based on FairRoot.

Les nanomatériaux : une caractérisation difficile ...  

NASA Astrophysics Data System (ADS)

The field of nanomaterials is of widespread interest since the beginning of the nineties. We describe several methods of synthesis of nanophased materials and of nanostructured materials. The problems related to the characterization of nanosized particles and to the influence of the synthesis method on their properties are illustrated first from a comparison of nanometric titanoferrites synthesized by two different methods, then by a phase transformation from face-centered cubic to hexagonal which takes place in Ni at a nanometer crystallite size and finally by the Rietveld analysis of phases found in TiO2 powders ground for short times. Depuis le début des années 90, les recherches sur les nanomatériaux ont connu un essor considérable. Nous décrivons ici différentes méthodes de synthèse de nanoparticules et de matériaux nanostructurés. Les problèmes liés à la caractérisation des particules nanométriques et à l'influence de la méthode de synthèse sur les propriétés sont illustrés par la comparaison de ferrites de titane nanométriques élaborés par deux méthodes différentes, par l'étude d'une transition Ni hexagonal - Ni cubique faces centrées liée à la taille et par la quantification par la méthode de Rietveld des phases présentes dans des poudres de TiO2 broyées.

Trust, confidence, procedural fairness, outcome fairness, moral conviction, and the acceptance of GM field experiments.  

PubMed

In 2005, Swiss citizens endorsed a moratorium on gene technology, resulting in the prohibition of the commercial cultivation of genetically modified crops and the growth of genetically modified animals until 2013. However, scientific research was not affected by this moratorium, and in 2008, GMO field experiments were conducted that allowed us to examine the factors that influence their acceptance by the public. In this study, trust and confidence items were analyzed using principal component analysis. The analysis revealed the following three factors: "economy/health and environment" (value similarity based trust), "trust and honesty of industry and scientists" (value similarity based trust), and "competence" (confidence). The results of a regression analysis showed that all the three factors significantly influenced the acceptance of GM field experiments. Furthermore, risk communication scholars have suggested that fairness also plays an important role in the acceptance of environmental hazards. We, therefore, included measures for outcome fairness and procedural fairness in our model. However, the impact of fairness may be moderated by moral conviction. That is, fairness may be significant for people for whom GMO is not an important issue, but not for people for whom GMO is an important issue. The regression analysis showed that, in addition to the trust and confidence factors, moral conviction, outcome fairness, and procedural fairness were significant predictors. The results suggest that the influence of procedural fairness is even stronger for persons having high moral convictions compared with persons having low moral convictions. PMID:22150405

Emergence of fairness in repeated group interactions.  

PubMed

Often groups need to meet repeatedly before a decision is reached. Hence, most individual decisions will be contingent on decisions taken previously by others. In particular, the decision to cooperate or not will depend on one's own assessment of what constitutes a fair group outcome. Making use of a repeated N-person prisoner's dilemma, we show that reciprocation towards groups opens a window of opportunity for cooperation to thrive, leading populations to engage in dynamics involving both coordination and coexistence, and characterized by cycles of cooperation and defection. Furthermore, we show that this process leads to the emergence of fairness, whose level will depend on the dilemma at stake. PMID:22587290

Fair and optimistic quantum contract signing  

SciTech Connect

We present a fair and optimistic quantum-contract-signing protocol between two clients that requires no communication with the third trusted party during the exchange phase. We discuss its fairness and show that it is possible to design such a protocol for which the probability of a dishonest client to cheat becomes negligible and scales as N{sup -1/2}, where N is the number of messages exchanged between the clients. Our protocol is not based on the exchange of signed messages: Its fairness is based on the laws of quantum mechanics. Thus, it is abuse free, and the clients do not have to generate new keys for each message during the exchange phase. We discuss a real-life scenario when measurement errors and qubit-state corruption due to noisy channels and imperfect quantum memories occur and argue that for a real, good-enough measurement apparatus, transmission channels, and quantum memories, our protocol would still be fair. Apart from stable quantum memories, the other segments of our protocol could be implemented by today's technology, as they require in essence the same type of apparatus as the one needed for the Bennett-Brassard 1984 (BB84) cryptographic protocol. Finally, we briefly discuss two alternative versions of the protocol, one that uses only two states [based on the Bennett 1992 (B92) protocol] and the other that uses entangled pairs, and show that it is possible to generalize our protocol to an arbitrary number of clients.

Fair bandwidth sharing at routers has several advantages, includingprotection of well-behaved flows and possible simplification of endto-end congestion control mechanisms. Traditional mechanisms to achievefair sharing (e.g., Weighted Fair Queueing, Flow Random Early Discard)require per-flow state to determine which packets to drop under congestion,and therefore are complex to implement at the interior of a high-speednetwork.

FAIR: a Horizon for Future Charming Physics  

SciTech Connect

The science goals underlying the future international Facility for Antiproton and Ion Research--FAIR--[1] that is being realized in Darmstadt span a broad range of research activities on the structure of matter. One component of this facility is directed towards studies of hadronic matter at the sub-nuclear level with beams of antiprotons. These studies focus on two key aspects: confinement of quarks and the generation of the hadron masses. These goals will be pursued by performing precision measurements of charged and neutral decay products from antiproton-proton annihilation in the charmonium mass region. In this talk I present some of the issues connected to FAIR in which the groups in Cracow and Juelich are extending and intensifying our cooperation.

Interactivity vs. fairness in networked linux systems  

SciTech Connect

In general, the Linux 2.6 scheduler can ensure fairness and provide excellent interactive performance at the same time. However, our experiments and mathematical analysis have shown that the current Linux interactivity mechanism tends to incorrectly categorize non-interactive network applications as interactive, which can lead to serious fairness or starvation issues. In the extreme, a single process can unjustifiably obtain up to 95% of the CPU! The root cause is due to the facts that: (1) network packets arrive at the receiver independently and discretely, and the 'relatively fast' non-interactive network process might frequently sleep to wait for packet arrival. Though each sleep lasts for a very short period of time, the wait-for-packet sleeps occur so frequently that they lead to interactive status for the process. (2) The current Linux interactivity mechanism provides the possibility that a non-interactive network process could receive a high CPU share, and at the same time be incorrectly categorized as 'interactive.' In this paper, we propose and test a possible solution to address the interactivity vs. fairness problems. Experiment results have proved the effectiveness of the proposed solution.

Various regulatory agencies have indicated the need to measure initial and ongoing competency among health care workers. Yet, what is competency and how can it be measured? In reality, competency assessment is about outcomes. Maintaining and advancing our knowledge, skills, and analytical abilities is important for achieving optimal patient outcomes. Competency assessment should go beyond the act of attending lectures and skills fairs. Competency assessment should be a time when nurses can demonstrate and document their problem-solving and decision-making skills, inclusion of best practices, and evidence of how those skills make a difference for the patients they care for.

NASA Astrophysics Data System (ADS)

FAIRNESS 2013 was the second edition in a series of workshops designed to bring together excellent international young scientists with research interests focused on physics at FAIR (Facility for Antiproton and Ion Research) and was held on 16–21 September 2013 in Berlin, Germany. The topics of the workshop cover a wide range of aspects in both theoretical developments and current experimental status, concentrated around the four scientific pillars of FAIR. FAIR is a new accelerator complex with brand new experimental facilities, that is currently being built next to the existing GSI Helmholtzzentrum for Schwerionenforschung close to Darmstadt, Germany. The spirit of the conference is to bring together young scientists, e.g. advanced PhD students and postdocs and young researchers without permanent position to present their work, to foster active informal discussions and build up of networks. Every participant in the meeting with the exception of the organizers gives an oral presentation, and all sessions are followed by an hour long discussion period. During the talks, questions are anonymously collected in box to stimulate discussions. Since the physics program of FAIR is very broad, this is reflected in the wide range of topics covered at the Conference: Physics of hot and dense nuclear matter, QCD phase transitions and critical point Nuclear structure, astrophysics and reactions Hadron spectroscopy, Hadrons in matter and Hypernuclei Special emphasis is put on the experiments CBM, HADES, PANDA, NuSTAR, as well as NICA and the RHIC low beam energy scan New developments in atomic and plasma physics For all of these different areas one invited speaker was selected to give a longer introductory presentation. The write-ups of the talks presented at FAIRNESS 2013 are the content of this issue of Journal of Physics: Conference Series and have been refereed according to the IOP standard for peer review. This issue constitutes therefore a collection of the forefront of research that is dedicated to the physics of FAIR. February 2014. Organizers of FAIRNESS 2013: Marco Destefanis, Tetyana Galatyuk, Fernando Montes, Diana Nicmorus, Hannah Petersen, Claudia Ratti, Laura Tolos, and Sascha Vogel.

Centaur D-1A nose fairing jettison test  

NASA Technical Reports Server (NTRS)

An experimental investigation was conducted to verify the functional and structural capability of the Centaur D-1A nose fairing. A full-scale flight-type nose fairing was jettisoned at the Lewis Research Center Space Power Chamber at simulated altitude. Two complete jettisons of the nose fairing were performed, one without aft helper springs and one with aft helper springs. A ''static'' rotation test was also performed to verify capability of the helper springs and to allow clearance measurements between the nose fairing and spacecraft envelope mock-up at certain discrete nose fairing rotation angles. Nose fairing trajectories, structural deflections, clearances, and hinge forces during jettison are presented. Data from subsequent Centaur D-1A flights, relative to nose fairing jettisons, are compared with the experimental results.

Quand la biopsie cutan?e peut ?tiqueter une ?pilepsie  

PubMed Central

La maladie de Lafora (ML) représente une forme rare et grave d’épilepsie myoclonique progressive. C'est une affection à transmission autosomique récessive, hétérogène sur le plan génétique. Nous rapportons le cas d'une adolescente de 16 ans, issue de parents consanguins de premier degré, qui présente depuis l’âge de 14 ans des crises d’épilepsie et des myoclonies. L'examen neurologique a montré un syndrome cérébelleux et une détérioration intellectuelle. La biopsie cutanée était indispensable pour orienter le diagnostic. La ML a un pronostic constamment fatal. L’étude histologique confirme le diagnostic et l’étude moléculaire peut aider à établir un conseil génétique.

Fairness overrides reputation: the importance of fairness considerations in altruistic cooperation  

PubMed Central

Behavioral findings in several strategic games indicate that people punish others if they think they are being treated unequally, even at the cost of minimizing their own material payoff. We investigated the primary driving force behind such non-self-regarding behavior, so-called, altruistic cooperation. In all of our studies, a mini ultimatum game was played either one-shot (in Experiment 1a and 1b) or repeatedly (Experiment 2), and rejections of inequitable distribution were taken as a measure of altruistic cooperation. In Experiment 1a, we replicated previous findings indicating that the key mechanism contributing to the emergence of altruistic cooperation is fairness considerations. In Experiment 1b, we delved into the relative importance of two aspects of fairness considerations (i.e., outcome fairness and intentions) and showed that both aspects were effective in determining the level of altruistic cooperation, with the contribution of intentions being more important. In Experiment 2, we investigated the effect of the opportunity for reputation building and future interaction on altruistic cooperation. We found that these factors became influential only when fairness considerations were weakened, particularly, as a result of the removal of the possible intentions behind an offer.

Do infants have a sense of fairness?  

PubMed Central

Two experiments examined infants’ expectations about how an experimenter should distribute resources and rewards to others. In Experiment 1, 19-month-olds expected an experimenter to divide two items equally, as opposed to unequally, between two individuals. Infants held no particular expectation when the individuals were replaced with inanimate objects, or when the experimenter simply removed covers in front of the individuals to reveal the items (instead of distributing them). In Experiment 2, 21-month-olds expected an experimenter to give a reward to each of two individuals when both had worked to complete an assigned chore, but not when one of the individuals had done all the work while the other played. Infants held this expectation only when the experimenter could determine through visual inspection who had worked and who had not. Together, these results provide converging evidence that infants in the second year of life already possess context sensitive-expectations relevant to fairness.

Privacy, Liveliness and Fairness for Reputation  

NASA Astrophysics Data System (ADS)

In various Internet applications, reputation systems are typical means to collect experiences users make with each other. We present a reputation system that balances the security and privacy requirements of all users involed. Our system provides privacy in the form of information theoretic relationship anonymity w.r.t. users and the reputation provider. Furthermore, it preserves liveliness, i.e., all past ratings can influence the current reputation profile of a user. In addition, mutual ratings are forced to be simultaneous and self rating is prevented, which enforces fairness. What is more, without performing mock interactions - even if all users are colluding - users cannot forge ratings. As far as we know, this is the first protocol proposed that fulfills all these properties simultaneously.

Nuclear Few-Body Physics at FAIR  

NASA Astrophysics Data System (ADS)

The FAIR facility, to be constructed at the GSI site in Darmstadt, will be addressing a wealth of outstanding questions within the realm of subatomic, atomic and plasma physics through a combination of novel accelerators, storage rings and innovative experimental set-ups. One of the key installations is the fragment separator Super-FRS that will be able to deliver an unprecedented range of radioactive ion beams (RIBs) in the energy range of 0-1.5 GeV/u to the envisaged experiments collected within the NuSTAR collaboration. This will in particular permit new experimental investigations of nuclear few-body systems at extreme isospins, also reaching beyond the drip-lines, using the NuSTAR-R3B set-up. The outcome of pilot experiments on unbound systems are reported, as well as crucial detector upgrades.

The Compressed Baryonic Matter experiment at FAIR  

NASA Astrophysics Data System (ADS)

The Compressed Baryonic Matter (CBM) experiment will be one of the major scientific pillars of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The goal of the CBM research program is to explore the QCD phase diagram in the region of high baryon densities using high-energy nucleus-nucleus collisions. This includes the study of the equation-of-state of nuclear matter at high densities, and the search for the deconfinement and chiral phase transitions. The CBM detector is designed to measure both bulk observables with large acceptance and rare diagnostic probes such as charmed particles and vector mesons decaying into lepton pairs. The layout and the physics performance of the proposed CBM experimental facility will be discussed.

From the Science Fair to the NASDAQ  

NASA Astrophysics Data System (ADS)

Electroanalytical chemistry has been a primary activity in Ph.D.-granting institutions since the 1940s. It has proved to be an excellent tool for research, enabling students to think in time and space and grasp thermodynamics, kinetics, and instrumentation principles as applied to accessible measurements. This personal perspective is an informal review of this dynamic field from the late 1950s to the present. During this period, the capability of instrumentation advanced by six orders of magnitude in many respects. The author began his career in 1960 with a high school science fair project on electrochemistry. This evolved into undergraduate, doctoral, and postdoctoral research, leading to a career in academia and industry.

Disease surveillance and emergency services at the 1982 World's Fair.  

PubMed Central

We designed a special surveillance system to detect health complaints of visitors to the 1982 World's Fair. Heat-related illness occurred during the first month of the Fair but was substantially reduced by public education, environmental modification, and provision of additional water fountains. There was no disruption of emergency health services in the communities surrounding the Fair. Advance planning and the provision of on-site medical services can minimize the public health impact of large gatherings.

BOOK REVIEW: Science Fair Projects: Physics  

NASA Astrophysics Data System (ADS)

I have often thought that the notion of a Science Fair is intrinsically a good one but have never set one up. With this book such an undertaking is possible, with 47 projects from which you can choose. Each project has a clearly stated purpose with an overview that contains the physics you need to get started. A hypothesis, or sometimes two, and a procedure detailing what the student should do follow this. The materials to be used are those you should be able to find at home, and safety guidelines as well as places the student needs adult help are clearly marked. Every project asks the student to write down the results of their experiment and decide whether or not their hypothesis was correct. There are also suggestions for taking each project further. Some of these projects are standard experiments that you may already do with students in class, for example, making plasticine boats, string telephones and levers. Most are interesting twists on standard experiments such as using a wedge as a simple machine, home-made spinning toys and the experiments with light bulbs. The latter are the only real cause for concern if students were to do these things at home as adult supervision would be essential. This is obviously an American book, though. Teachers in British classrooms would need to work out how to deal with the references to temperature in Fahrenheit and mass in ounces. Length is usually given in centimetres as well as inches. Translations of soda bottles and bobby pins would also be needed. This book is designed to be full of ideas and to give structure to projects students can do at home, not to provide ideas that you can transport into the classroom. It does this very well and I would recommend it to anyone thinking of starting up a Science Fair. Alternatively, this is an excellent resource for more interesting homework assignments that would put more responsibility on the student and give them something fun to do.

Fairness as partiality aversion: the development of procedural justice.  

PubMed

Adults and children dislike inequity-people being paid unequally for equal work. However, adults will allow inequity if the inequity is determined using an impartial procedure, indicating that they value procedural justice. It is unknown whether children value procedural justice when distributing resources. We investigated whether 5- to 8-year-old children would willingly create inequity between two recipients if they could do so using an impartial procedure. In Experiment 1, children preferred to use an impartial procedure (spinning a wheel that gave both recipients an equal chance to get a resource) over a partial procedure (spinning a wheel that gave one recipient a much better chance to get the resource). In Experiments 2 and 3, children preferred to use the same impartial procedure to assign a resource to one of two recipients, even over an option of keeping things equal by throwing the resource in the trash. Importantly, children preferred to throw the resource in the trash to uphold equality when the only other option was a partial procedure. Older children showed a stronger aversion to using partial procedures than younger children. These results suggest that children value procedural justice increasingly during middle childhood and that their fairness concerns may be more about avoiding partiality than inequity per se.

Fair loss-tolerant quantum coin flipping  

SciTech Connect

Coin flipping is a cryptographic primitive in which two spatially separated players, who do not trust each other, wish to establish a common random bit. If we limit ourselves to classical communication, this task requires either assumptions on the computational power of the players or it requires them to send messages to each other with sufficient simultaneity to force their complete independence. Without such assumptions, all classical protocols are so that one dishonest player has complete control over the outcome. If we use quantum communication, on the other hand, protocols have been introduced that limit the maximal bias that dishonest players can produce. However, those protocols would be very difficult to implement in practice because they are susceptible to realistic losses on the quantum channel between the players or in their quantum memory and measurement apparatus. In this paper, we introduce a quantum protocol and we prove that it is completely impervious to loss. The protocol is fair in the sense that either player has the same probability of success in cheating attempts at biasing the outcome of the coin flip. We also give explicit and optimal cheating strategies for both players.

We consider the implications of this behavior for exhibitors and present a model of visitor-exhibitor interaction. Trade fairs should be viewed in a broader network sense.

The role of authority power in explaining procedural fairness effects.  

PubMed

Building on fairness heuristic theory, fairness theory, and trust development models, we argue that unfairly enacted procedures decrease followers' trust in the authority particularly when authorities have high power over their followers. Moreover, we expected trust to mediate procedural fairness effects on followers' attitudes (authorities' legitimacy and charisma attributed to authorities) and organizational citizenship behavior. Procedural fairness effects on these variables, as mediated by trust, should therefore also be stronger when authority power is high. The results of a single- and multisource field study and a laboratory experiment supported these predictions. These studies support the role of authority power as a theoretically and practically relevant moderator of procedural fairness effects and show that its effectiveness is explained through trust in authorities.

More on benchmarks of fairness: response to Ballantyne.  

PubMed

This paper challenges the fitness of Angela Ballantyne's proposed theory of exploitation by situating her 'fair risk account' in an ongoing dialogue about the adequacy conditions for benchmarks of fairness. It identifies four adequacy conditions: (1) the ability to focus on level rather than type of benefit; (2) the ability to focus on micro-level rather than macro-level fairness; (3) the ability to prevent discrimination based on need; and (4) the ability to prescribe a certain distribution as superior to all others. While the fair risk account satisfies the first condition, this paper argues that it has difficulty satisfying the last three conditions. Ballantyne's proposal includes several new and promising features, but in order for the fair risk account to be useful in identifying and preventing exploitation, Ballantyne must either clarify and augment her theory or challenge the relevance of the adequacy conditions it fails to meet.

La Station Laser ultra mobile: de l'Obtention d'une Exactitude centimétrique des Mesures à des Applications en Océanographie et Géodésie Spatiales  

NASA Astrophysics Data System (ADS)

La Station Laser Ultra Mobile est la plus petite station de télémétrie laser au monde, ne pesant que 300 kg, dédiée à la poursuite de satellites équipés de rétroréflecteurs laser. Elle utilise un petit télescope de 13 cm de diamètre placé sur une monture issue d'un théodolite de précision et motorisé, un laser très compact et une photodiode à avalanche permettant la détection au niveau du simple photo-électron. Les premières expériences (Corse, fin 1996) ont révélé de nombreuses instabilités dans la qualité des mesures. Ce travail concerne l'étude et la mise en place de nombreuses modifications techniques afin d'atteindre une exactitude centimétrique des mesures et de pouvoir participer à la campagne de validation des orbites et d'étalonnage de l'altimètre du satellite océanographique JASON-1 (2001). La précision instrumentale souhaitée a été vérifiée avec succès en laboratoire. Outre cet aspect instrumental et métrologique, une analyse a été développée afin de pouvoir estimer l'exactitude et la stabilité des observations de la station mobile après intégration des modifications. A partir d'une expérience de co-localisation entre les deux stations laser fixe du plateau de Calern, l'analyse est basée sur l'ajustement, par station, de coordonnées et d'un biais instrumental moyen à partir d'une orbite de référence des satellites LAGEOS. Des variations saisonnières ont été mises en évidence dans les séries temporelles des différentes composantes. La comparaison locale des déformations de la croûte terrestre se traduisant par des variations d'altitude issues des données laser a montré une cohérence remarquable avec les mesures du gravimètre absolu transportable FG5. Des signaux de même amplitude ont aussi été observés par GPS. Ces variations sont également mises en évidence à l'échelle mondiale et leur interprétation géophysique est faite (combinaison des effets de marées terrestres et polaire et des effets de charge atmosphérique).

PubMed Central

La tumeur Fibreuse solitaire (TFS) est une prolifération fusocellulaire rare, souvent de localisation intra-thoracique. Nous rapportons le cas d'une localisation exceptionnelle au niveau du 3ème doigt de la main droite. En l'absence de marqueur spécifique l'interprétation de l'immuno-marquage dépend du contexte histo-morphologique. La similitude avec les différents néoplasmes à cellules fusiformes des tissus mous rend le diagnostic de ces tumeurs mésenchymateuses difficile et tardif. Dans 20à 30% des cas le comportement de la TFS est celui d'une tumeur maligne localement agressive et récidivante, avec des métastases rares et tardives. Ce comportement impose une surveillance prolongée après exérèse chirurgicale.

Biological assessment of Ariane 5 fairing

United Nations Space Treaties [United Nations, Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, 610 UNTS 205, resolution 2222(XXI) of December 1966., United Nations, Agreement Governing the Activities of States on the Moon and Other Celestial Bodies, UN doc A/RES/34/68, resolution 38/68 of December 1979.] require the preservation of planets and of Earth from contamination. All nations part to these Treaties shall take measures to prevent forward and backward contamination during missions exploring our solar system. As observer for the United Nations Committee on Peaceful Uses of Outer Space, the COSPAR (Committee of Space Research) defines and handles the applicable policy and proposes recommendations to Space Agencies [COSPAR Planetary Protection Panel, Planetary Protection Policy accepted by the COSPAR Council and Bureau, 20 October 2002, amended 24 March 2005. http://www.cosparhq.org/scistr/PPPolicy.htm.]. The goal is to protect celestial bodies from terrestrial biological contamination as well as to protect the Earth environment from an eventual biohazard which may be carried by extraterrestrial samples or by space systems returning to Earth. According to the applicable specifications, including in our case the French requirements [CNES, System Safety. Planetary Protection Requirements. Normative referential CNES RNC-CNES-R-14, CNES Toulouse, ed. 4, 04 October 2002.], the prevention of forward contamination is accomplished by reducing the bioburden on space hardware to acceptable, prescribed levels, including in some instances system sterilization, assembling and integrating the appropriate spacecraft systems in cleanrooms of appropriate biological cleanliness, avoiding or controlling any recontamination risk, and limiting the probability impact of space systems. In order to prepare for future exploration missions [Debus, A., Planetary protection: organization requirements and needs for future planetary exploration missions, ESA conference publication SP-543, pp 103 114, 2003.], and in particular for missions to Mars requiring to control the spacecraft bioburden, a test program has been developed to evaluate the biological contamination under the fairing of the Ariane 5 launcher.

SE-FIT  

NASA Technical Reports Server (NTRS)

The mathematical theory of capillary surfaces has developed steadily over the centuries, but it was not until the last few decades that new technologies have put a more urgent demand on a substantially more qualitative and quantitative understanding of phenomena relating to capillarity in general. So far, the new theory development successfully predicts the behavior of capillary surfaces for special cases. However, an efficient quantitative mathematical prediction of capillary phenomena related to the shape and stability of geometrically complex equilibrium capillary surfaces remains a significant challenge. As one of many numerical tools, the open-source Surface Evolver (SE) algorithm has played an important role over the last two decades. The current effort was undertaken to provide a front-end to enhance the accessibility of SE for the purposes of design and analysis. Like SE, the new code is open-source and will remain under development for the foreseeable future. The ultimate goal of the current Surface Evolver Fluid Interface Tool (SEFIT) development is to build a fully integrated front-end with a set of graphical user interface (GUI) elements. Such a front-end enables the access to functionalities that are developed along with the GUIs to deal with pre-processing, convergence computation operation, and post-processing. In other words, SE-FIT is not just a GUI front-end, but an integrated environment that can perform sophisticated computational tasks, e.g. importing industry standard file formats and employing parameter sweep functions, which are both lacking in SE, and require minimal interaction by the user. These functions are created using a mixture of Visual Basic and the SE script language. These form the foundation for a high-performance front-end that substantially simplifies use without sacrificing the proven capabilities of SE. The real power of SE-FIT lies in its automated pre-processing, pre-defined geometries, convergence computation operation, computational diagnostic tools, and crash-handling capabilities to sustain extensive computations. SE-FIT performance is enabled by its so-called file-layer mechanism. During the early stages of SE-FIT development, it became necessary to modify the original SE code to enable capabilities required for an enhanced and synchronized communication. To this end, a file-layer was created that serves as a command buffer to ensure a continuous and sequential execution of commands sent from the front-end to SE. It also establishes a proper means for handling crashes. The file layer logs input commands and SE output; it also supports user interruption requests, back and forward operation (i.e. undo and redo), and others. It especially enables the batch mode computation of a series of equilibrium surfaces and the searching of critical parameter values in studying the stability of capillary surfaces. In this way, the modified SE significantly extends the capabilities of the original SE.

Non-Traditional Characteristics of a Successful Science Fair Project

Although science fairs are designed to help students develop inquiry skills, including writing research proposals, working with peers, and sharing experimental findings, simply holding a science fair is no guarantee that students will actually acquire these essential skills. Participation in a science fair should not be viewed as the "one shot" opportunity for teachers to involve their students in inquiry, but rather it should provide both extensions and reinforcements to skills that were developed over time through a variety of classroom activities. This article outlines six specific characteristics for students that are essential to the completion of a quality project.

Structural testing of the D-1A Centaur nose fairing was completed to determine the loads imposed during flight on the latch bolts of the fairing separation system. This testing was conducted to supplement and/or verify the analytic techniques used in calculating bolt loads for the D-1A, and to gain insight into the general structural behavior of separation latch systems. It was shown that the assumed bolt load magnification due to prying action of the latch fittings on the bolt does occur, but is strongly dependent on fairing shell stiffness.

Réalisation d'un réseau de pièges annulaires : une première étape vers une porte logique quantique avec des atomes froids  

NASA Astrophysics Data System (ADS)

L'objectif de ce projet est de réaliser une porte logique quantique basée sur l'interaction d'atomes dans deux sites voisins dans un réseau optique très désaccordé. Le principal obstacle rencontré vient du faible taux d'occupation des sites de tels réseaux. Nous proposons ici de mettre en oeuvre un nouveau type de réseaux optiques qui devraient pallier cette limitation. Il s'agit d'un réseau unidimensionnel de pièges annulaires “empilés” avec une période de ?/2. L'utilisation d'axicons conduit à une géométrie adaptée des faisceaux et donne le confinement radial dans les anneaux. Le mouvement azimutal peut également être limité par une force auxiliaire. Le bon taux d'occupation est lié au faible nombre de sites remplis à partir du nuage d'atomes froids initial.

Electromagnetic Cavity Effects from Transmitters Inside a Launch Vehicle Fairing  

NASA Technical Reports Server (NTRS)

This paper provides insight into the difficult analytical issue for launch vehicles and spacecraft that has applicability outside of the launch industry. Radiation from spacecraft or launch vehicle antennas located within enclosures in the launch vehicle generates an electromagnetic environment that is difficult to accurately predict. This paper discusses the test results of power levels produced by a transmitter within a representative scaled vehicle fairing model and provides preliminary modeling results at the low end of the frequency test range using a commercial tool. Initially, the walls of the fairing are aluminum and later, layered with materials to simulate acoustic blanketing structures that are typical in payload fairings. The effects of these blanketing materials on the power levels within the fairing are examined.

Ground test program for new Atlas payload fairings  

NASA Technical Reports Server (NTRS)

To establish the competitiveness of the revitalized family of Atlas launch vehicles (I, II, IIA, and IIAS) a new series of payload fairings, an 11-foot and a 14-foot diameter version, were designed to accommodate the widest possible variety of satellites. Because these aluminum fairings are new designs, the plant at which they are produced is new, and launch customers are very anxious to fly their payloads, an ambitious and efficient test program is essential. Five major tests have been planned for completion within the span of one calendar year. One of these has been completed, with every indication that it was a success, one is currently under way, and two more are scheduled to start in the month of April. Through effective use of test assets, facilities, and personnel, all testing will be completed, allowing the fairing design to be completely characterized and then qualified through analysis prior to first launch of each of the fairings.

Acoustic fill factors for a 120 inch diameter fairing  

NASA Technical Reports Server (NTRS)

Data from the acoustic test of a 120-inch diameter payload fairing were collected and an analysis of acoustic fill factors were performed. Correction factors for obtaining a weighted spatial average of the interior sound pressure level (SPL) were derived based on this database and a normalized 200-inch diameter fairing database. The weighted fill factors were determined and compared with statistical energy analysis (VAPEPS code) derived fill factors. The comparison is found to be reasonable.

A signal processing approach to fair surface design  

Microsoft Academic Search

In this paper we describe a new tool for interactive free-form fair surface design. By generalizing classical discrete Fourier analysis to two-dimensional discrete surface signals – functions defined on polyhedral surfaces of arbitrary topology –, we reduce the problem of surface smoothing, or fairing, to low-pass filtering. We describe a very simple surface signal low-pass filter algorithm that applies to

Silence et divulgation dans des familles d'adolescents vivant avec le VIH depuis la naissance : une exploration qualitative  

PubMed Central

OBJECTIF : Les études ciblant les enfants nés avec le VIH se sont principalement intéressées à la période précédant l’annonce du diagnostic à l’enfant. L’objectif de cette étude est d’explorer les dynamiques de communication intrafamiliale suivant l’annonce du diagnostic. MÉTHODOLOGIE : Vingt-neuf jeunes (de dix à 18 ans) vivant avec le VIH depuis la naissance ont accordé des entrevues individuelles semi-dirigées portant sur : 1) le dévoilement du statut sérologique, 2) leurs relations familiales et 3) l’éducation sexuelle en milieu familial. Les témoignages ont fait l’objet d’une analyse de contenu. RÉSULTATS : Les jeunes ont appris en moyenne à l’âge de 11 ans leur diagnostic VIH+. La dynamique qui s’installe après cette annonce apparaît régie par le silence : les échanges qui s’ensuivent portent en majorité sur des questions relatives à la médication et à la prévention d’une transmission sexuelle du virus. Ce silence préserverait l’équilibre familial en occupant trois fonctions : protéger la mère d’un sentiment de culpabilité à l’égard de la transmission, assurer l’harmonie familiale, se sentir normal face aux autres. Le diagnostic de l’adolescent n’est généralement pas révélé à la famille élargie, préservant ainsi leur intégration au sein de la famille en les protégeant du rejet, de la trahison et du jugement. EXPOSÉ : Les fonctions du silence et du secret occupent une place stabilisatrice importante au sein de la famille. Toutefois, elles contribuent à isoler les adolescents d’une forme de soutien affectif dont ils ont pourtant besoin. Des pistes d’intervention sont suggérées.

Attack and improvements of fair quantum blind signature schemes  

NASA Astrophysics Data System (ADS)

Blind signature schemes allow users to obtain the signature of a message while the signer learns neither the message nor the resulting signature. Therefore, blind signatures have been used to realize cryptographic protocols providing the anonymity of some participants, such as: secure electronic payment systems and electronic voting systems. A fair blind signature is a form of blind signature which the anonymity could be removed with the help of a trusted entity, when this is required for legal reasons. Recently, a fair quantum blind signature scheme was proposed and thought to be safe. In this paper, we first point out that there exists a new attack on fair quantum blind signature schemes. The attack shows that, if any sender has intercepted any valid signature, he (she) can counterfeit a valid signature for any message and can not be traced by the counterfeited blind signature. Then, we construct a fair quantum blind signature scheme by improved the existed one. The proposed fair quantum blind signature scheme can resist the preceding attack. Furthermore, we demonstrate the security of the proposed fair quantum blind signature scheme and compare it with the other one.

Ut?rus bicorne bicervical perm?able: d?couverte fortuite lors d'une c?sarienne d'urgence chez une multipare lushoise  

PubMed Central

L'utérus bicorne bicervical perméable est une malformation utérine assez rare et son diagnostic est souvent posé fortuitement au cours d'un examen fait pour autre but. Il est asymptomatique et au cours d'une grossesse, cette malformation peut passer inaperçue si aucune surveillance prénatale n'a été faite. Nous rapportons un cas d'utérus bicorne bicervical perméable découvert fortuitement lors d'une césarienne indiquée urgemment pour une dystocie dynamique de type hypercinétique rebelle au traitement chez une multipare âgée de 30 ans. L'intérêt de ce cas est de montrer le pronostic obstétrical chez les femmes fertiles porteuses de cette malformation utérine.

Une alternative au cobalt pour la synthese de nanotubes de carbone monoparoi par plasma inductif thermique  

NASA Astrophysics Data System (ADS)

Les nanotubes de carbone de type monoparoi (C-SWNT) sont une classe recente de nanomateriaux qui ont fait leur apparition en 1991. L'interet qu'on leur accorde provient des nombreuses proprietes d'avant-plan qu'ils possedent. Leur resistance mecanique serait des plus rigide, tout comme ils peuvent conduire l'electricite et la chaleur d'une maniere inegalee. Non moins, les C-SWNT promettent de devenir une nouvelle classe de plateforme moleculaire, en servant de site d'attache pour des groupements reactifs. Les promesses de ce type particulier de nanomateriau sont nombreuses, la question aujourd'hui est de comment les realiser. La technologie de synthese par plasma inductif thermique se situe avantageusement pour la qualite de ses produits, sa productivite et les faibles couts d'operation. Par contre, des recherches recentes ont permis de mettre en lumiere des risques d'expositions reliees a l'utilisation du cobalt, comme catalyseur de synthese; son elimination ou bien son remplacement est devenu une preoccupation importante. Quatre recettes alternatives ont ete mises a l'essai afin de trouver une alternative plus securitaire a la recette de base; un melange catalytique ternaire, compose de nickel, de cobalt et d'oxyde d'yttrium. La premiere consiste essentiellement a remplacer la proportion massique de cobalt par du nickel, qui etait deja present dans la recette de base. Les trois options suivantes contiennent de nouveaux catalyseurs, en remplacement au Co, qui sont apparus dans plusieurs recherches scientifiques au courant des dernieres annees: le dioxyde de zircone (ZrO2), dioxyde de manganese (MnO2) et le molybdene (Mo). La methode utilisee consiste a vaporiser la matiere premiere, sous forme solide, dans un reacteur plasma a haute frequence (3 MHz) a paroi refroidi. Apres le passage dans le plasma, le systeme traverse une section dite de "croissance", isolee thermiquement a l'aide de graphite, afin de maintenir une certaine plage de temperature favorable a la synthese de C-SWNT. Le produit final est par la suite recolte sur des filtres metalliques poreux, une fois le systeme mis a l'arret. Dans un premier temps, une analyse thermodynamique, calculee avec le logiciel Fact-Sage, a permis de mettre en lumiere l'etat des differentes produits et reactifs, tout au long de leur passage dans le systeme. Elle a permis de reveler la similitude de composition de la phase liquide du melange catalytique ternaire de base, avec celui du melange binaire, avec nickel et oxyde d'yttrium. Par la suite, une analyse du bilan d'energie, a l'aide d'un systeme d'acquisition de donnees, a permis de determiner que les conditions operatoires des cinq echantillons mis a l'essai etaient similaires. Au total, le produit final a ete caracterise a l'aide de six methodes de caracterisations differentes : l'analyse thermogravimetrique, la diffraction de rayons X, la microscopie electronique a balayage a haute resolution (HRSEM), la microscopie electronique a transmission (MET), la spectroscopie RAMAN, ainsi que la mesure de la surface specifique (BET). Les resultats de ces analyses ont permis de constater, de facon coherente, que le melange a base de molybdene etait celui qui produisait la moins bonne qualite de produit. Ensuite, en ordre croissant, s'en suivait du melange a base de MnO2 et de ZrO2. Le melange de reference, a base de cobalt, est au deuxieme rang en matiere de qualite. La palme revient au melange binaire, dont la proportion est double en nickel. Les resultats de ce travail de recherche permettent d'affirmer qu'il existe une alternative performante au cobalt pour effectuer la synthese de nanotubes de carbone monoparoi, par plasma inductif thermique. Cette alternative est l'utilisation d'un melange catalytique binaire a base de nickel et d'oxyde d'yttrium. Il est suggere que les performances plus faibles des recettes alternatives, moins performantes, pourraient etre expliquees par le profil thermique fixe du reacteur. Ceci pourrait favoriser certains melanges, au detriment des autres, qui possedent des proprietes thermodynamiqu

Une porte optique intensificatrice picoseconde a gain eleve: Caracterisation et application potentielle en imagerie de petits objets places dans des milieux diffusants  

NASA Astrophysics Data System (ADS)

Dans cette etude, nous avons developpe un amplificateur a colorant possedant ces deux caracteristiques. Le colorant choisi, l'iodure de 3,3'-dimethyloxatricarbocyanine (methyl-DOTCI), possede un epaulement dans la bande d'absorption a 620 nm ce qui convient bien a notre pompe femtoseconde. De plus, son maximum de fluorescence est a 720 nm ce qui est particulierement interessant dans le cas des etudes avec des tissus biologiques humains. En effet, la fenetre dite "therapeutique" se situe dans les longueurs d'onde rouge et proche infrarouge. Le phenomene d'amplification, qui se produit dans des conditions experimentales precises, est en fait une emission stimulee du colorant qui est largement favorisee par rapport a sa fluorescence naturelle (emission spontanee). L'arrivee du signal incident, dont la longueur d'onde correspond au saut energetique entre l'etat fondamental et l'etat excite ou se trouvent les molecules, provoque une avalanche coherente de celles-ci vers l'etat fondamental generant ainsi l'emission stimulee. Une des conditions necessaires pour l'obtention d'un gain eleve est que la duree de l'impulsion de pompe soit inferieure au temps de relaxation des molecules ainsi qu'inferieure au temps requis pour effectuer un trajet dans la cellule de colorant. Ceci nous a permis d'amplifier un signal incident par un facteur entre 103 et 104. De plus, ce gain eleve n'est observe qu'a l'interieur d'une fenetre temporelle d'environ 10 picosecondes. Nous avons integre cet amplificateur a notre montage de transillumination afin d'acquerir des images d'un patron de lignes opaques immerge dans un milieu diffusant liquide. Des images de lignes ayant une resolution spatiale de 200 mum ont ete obtenues. La cible etait placee au centre d'un melange contenant des proportions variables de lait et d'eau. Deux longueurs de trajet optique dans la solution ont ete utilisees: 30 et 50 mm. Pour determiner les proprietes optiques de notre milieu diffusant, nous avons mis au point une technique de caracterisation basee sur la distribution radiale des photons transmis a travers le milieu. Deux parametres de transport, les coefficients de diffusion effectif (mus') et d'absorption (mu a), caracterisent la forme et l'amplitude du profil radial. Le fit des courbes experimentales a des courbes simulees nous a permis d'extraire ces coefficients. Les courbes simulees ont ete realisees grace a une simulation Monte Carlo qui incorpore les conditions experimentales de notre montage de caracterisation. (Abstract shortened by UMI.)

Hosting a Successful Science Fair to Boost Interest in Science  

NASA Astrophysics Data System (ADS)

Science fairs are a popular way for junior and senior high school students (grades 7 through 12) to display science and engineering projects and participate in a competition for prizes and honors. In the state of Ohio students can advance through their school fairs to district science fairs and then on to the State Science Day in early May. The University of Cincinnati (UC) has hosted one of the Ohio district science fairs since 2005 - the official name is the UC Science and Engineering Expo (UCSEE). The University hosts between 300 and 400 student projects at this event. The day itself includes the training of the 200+ judges, the actual judging, activities for the students' families and friends, tours of the UC campus facilities, and culminates with a guest speaker and an awards ceremony. The students compete for prizes and scholarships worth approximately 50k and over 100 of the UCSEE projects typically advance to participate in State Science Day. Additionally some top projects from the UCSEE are also sent directly to the International Science and Engineering Fair (ISEF). The authors have been heavily involved in the planning, organization and production of the UCSEE since UC began offering it in 2005. Much of the planning and background work, as well as memories, from this major project will be discussed in this presentation.

The Georgia State Fair, Macon, 1886-1960  

NSDL National Science Digital Library

Seven decades ago, one "Jaydee the Great" wowed crowds at the Georgia State Fair in Macon with his high trapeze novelty act. That wasn't all that was happening at the State Fair of course and visitors with an interest in American history, entertainment, state fairs, and Georgia history will find plenty to hold their attention within this nice digital collection. The collection was created by the Digital Library of Georgia, and it documents the evolution of the state fair in Macon from 1886 to 1960. Here visitors can look over 150 black and white photographs, along with a selection of fliers advertising the fair. Most of the photographs depict county agricultural exhibits whose function was to promote a variety of farm produce and homemade items. The collection also has a number of photographs documenting community canning projects which took place during World War II. Visitors can search the collection via a search engine, or they may just wish to just browse around, which can be pretty fun as well.

Ségrégation interfaciale et rupture: l'apport d'une approche atomistique ``mixte''  

NASA Astrophysics Data System (ADS)

Dans un alliage, toute modification de l'environnement cristallographique s'accompagne d'une variation des concentrations locales des constituants de l'alliage. La ségrégation peut ainsi être induite par des distorsions de liaisons, comme au coeur des joints de grains, ou par des variations du nombre de coordination, comme en surface. Pour modéliser ces variations de composition interfaciale, les approches vont de la thermodynamique phénoménologique qui ne prend pas en compte la structure atomique des interfaces jusqu'aux calculs ab initio, qui ne permettent guère d'appréhender les forces motrices de la ségrégation interfaciale. Nous montrerons l'apport d'une approche `mixte' couplant modèle de gaz sur réseau et potentiels interatomiques dérivés de la structure électronique. Ceux-ci permettent de calculer les paramètres énergétiques du modèle de gaz sur réseau tout en prenant en compte l'influence des relaxations des distances interatomiques. Grâce à cette approche, nous pourrons comparer les forces motrices responsables des ségrégations superficielle et intergranulaire et discuter du rôle de la ségrégation interfaciale quand un joint de grains se scinde en deux surfaces en tête de fissure.

Croissance et forme de l'hyphe modelées par une instabilité  

NASA Astrophysics Data System (ADS)

We propose a theory of growth and form of hyphae in analogy with dendritic growth, the basic ingredients for the organization of the hyphal tip being the vesicles used for the growth and the proton pumps at the origin of membrane potential. The uniform growth may be unstable, favoring the formation of vesicle clusters separated with a characteristic distance essentially determined by the dependance of the proton current with the internal pH and the membrane potential, the ionic current entering the more depolarized sites of the membrane where the aggregates form. This model is well adapted to the hyphoïd curve model [CITE], since it allows to propose an organization of the hyphal tip coupling proton currents and vesicle motions. One can determine the aggregation rate of a Spitzenkörper N as a function of the symport current and thus the external concentration of the co-transported substance, as well as a length scale ? ? d ?? / ?1/4 which can be associated to the current loop size. These first results are in good agreement with experimental results, suggesting that the coupling between vesicles and ionic channels is an essential mechanism of the morphogenesis of these organisms. Nous proposons une théorie de la croissance et de la forme de l'hyphe en analogie avec la croissance dendritique, les ingrédients de base de l'organisation de la pointe de l'hyphe étant des vésicules utilisées pour la croissance ainsi que des pompes à proton à l'origine du potentiel de membrane. La croissance uniforme peut être instable, favorisant la formation d'agrégats de vésicules distants d'une distance caractéristique essentiellement déterminée par la dépendance du courant de proton avec le pH interne et le potentiel de membrane, le courant ionique entrant aux lieux les plus dépolarisés de la membrane où se trouvent justement les agrégats. Ce modèle s'adapte très bien à celui de la courbe hyphoïde [CITE] puisqu'il permet de proposer une organisation de la pointe de l'hyphe couplant le courant de protons et le mouvement des vésicules. On peut ainsi déterminer le taux d'agrégation par unité de temps du Spitzenkörper N en fonction du courant de symport et donc de la concentration externe de substance co-transportée, ainsi qu'une échelle de longueur ? ? d ?? / ?1/4 que l'on peut associer à la longueur de boucle de courant. Ces premiers résultats sont en bon accord avec les résultats expérimentaux existants suggérant que le couplage entre les vésicules et les canaux ioniques est un mécanisme essentiel de la morphogenèse de ces organismes.

Science Sampler: A (minty) fresh approach to science fair projects  

NSDL National Science Digital Library

Many students are excited at the prospect of doing a science fair project, but they don't know how to go about asking an appropriate question or designing an experiment to answer their question. This class activity allows students to quickly "do" a class science fair project in order to see how it's done. It's also a great way to introduce concepts of controlling variables and testing multiple subjects using an inexpensive breath mint. Even if you do not do science fair projects with your class, this is a terrific activity for the beginning of the year as an introduction to the process of scientific inquiry. Students discover how to ask a simple question and collect data to answer it in a step-by-step fashion.

Justice- and fairness-related behaviors in nonhuman primates  

PubMed Central

A distinctive feature across human societies is our interest in justice and fairness. People will sometimes invest in extremely costly behavior to achieve fair outcomes for themselves and others. Why do people care so much about justice? One way to address this is comparatively, exploring behaviors related to justice and fairness in other species. In this paper, I review work exploring responses to inequity, prosocial behavior, and other relevant behaviors in nonhuman primates in an effort to understand both the potential evolutionary function of these behaviors and the social and ecological reasons for the individual differences in behavior. I also consider how these behaviors relate to human behavior, particularly in the case of experimental studies using games derived from experimental economics to compare nonhuman primates’ responses to those of humans in similar experimental conditions. These results emphasize the importance of a comparative approach to better understand the function and diversity of human behavior.

Procedural fairness in medical investigations and disciplinary proceedings.  

PubMed

In recent times, certain well-publicised cases involving allegations of inadequate and dangerous medical practice have led to a number of reviews into, and consequent changes to, the New South Wales medical regulatory and disciplinary system. The overwhelming focus has been upon both whether the existing system provided sufficient protection for the public from dangerous or under-performing medical practitioners and what was needed to ensure such protection. While the focus upon public protection is unquestionable and laudable, this still leaves considerable scope for ensuring a medical practitioner is afforded procedural fairness during the course of investigative and disciplinary processes. It is questionable whether procedural fairness is being afforded where to do so does not compromise the protection of the public. It is argued that only limited changes are required to create a system which affords procedural fairness without compromising the integrity of the system. PMID:19205311

Fairness modulates non-conscious facial mimicry in women  

PubMed Central

In societies with high cooperation demands, implicit consensus on social norms enables successful human coexistence. Mimicking other people's actions and emotions has been proposed as a means to synchronize behaviour, thereby enhancing affiliation. Mimicry has long been thought to be reflexive, but it has recently been suggested that mimicry might also be motivationally driven. Here, we show during an economic bargaining game that automatic happy mimicry of those making unfair offers disappears. After the bargaining game, when the proposers have acquired either a fair or unfair reputation, we observe increased angry mimicry of proposers with an unfair reputation and decreased angry mimicry of fair proposers. These findings provide direct empirical evidence that non-conscious mimicry is modulated by fairness. We interpret the present results as reflecting that facial mimicry in women functions conditionally, dependent on situational demands.

Status of the Design of the Fair Storage Rings  

NASA Astrophysics Data System (ADS)

Three storage rings with a maximum magnetic rigidity of 13 Tm are foreseen as part of the FAIR project. They will mainly serve the preparation of intense secondary beams of antiprotons and rare isotopes, which are produced with high intensity proton and heavy ion beams, respectively. Cooling, by stochastic and electron cooling, and accumulation as well as deceleration of the secondary beams are manipulation techniques which are foreseen. Internal targets and collisions of rare isotope beams with electrons or antiprotons in a collider set-up will be employed in physics experiments studying the properties of the secondary beams. This report summarizes the latest design work for the FAIR storage rings.

Process fairness refers to people’s perceptions of how fairly they are treated in the course of interacting with another party. Conceptually distinct from outcome fairness, it subsumes procedural fairness, interpersonal fairness, and the like. As recipients of decisions, we generally want to be treated with more rather than with less process fairness. As agents of decisions, we often would rather

L'?valuation et la prise en charge des enfants et des adolescents victimes d'une commotion li?e ? un sport  

PubMed Central

RÉSUMÉ Les commotions sont des blessures sportives fréquentes, et elles sont particulièrement courantes chez les enfants et les adolescents qui participent à des sports organisés ou à des activités récréatives. Les symptômes de commotion peuvent être subtils et négligés par les athlètes, les entraîneurs et les parents. Un enfant ou un adolescent qui est victime d’une commotion devrait être immédiatement retiré du jeu et être évalué par un médecin dans les plus brefs délais. Il devrait éviter les activités physiques et cognitives pour se remettre de la commotion. Une fois les symptômes complètement résorbés au repos, l’athlète peut suivre un protocole d’effort graduel, supervisé par un médecin, avant d’obtenir l’autorisation médicale de retourner au jeu. Il est essentiel que tous ceux qui participent aux activités sportives pour les enfants et les adolescents connaissent les signes et symptômes de commotion afin qu’on puisse poser un diagnostic exact et rapide et amorcer une évaluation et une prise en charge convenables. Le présent document de principes remplace celui qui a été publié en 2006.

Le volvulus gastrique est une rotation anormale de l'estomac autour de son axe. La forme aiguë constitue une urgence chirurgicale. Le diagnostic est souvent retardé en raison d'une symptomatologie fréquemment non spécifique. Des signes respiratoires tels la dyspnée et le hoquet peuvent révéler cette pathologie. Les auteurs rapportent une nouvelle observation de volvulus gastrique aigu chez un adolescent de 17 ans, diagnostiqué par la tomodensitométrie, et confirmé par une intervention chirurgicale. Le traitement est chirurgical et consiste à détordre et fixer l'estomac pour prévenir la récidive.

La pneumatose kystique intestinale est la présence de bulles gazeuses dans la paroi et les séreuses du tube digestif. Il s'agit d'une pathologie bénigne, rare, de diagnostic radiologique et de traitement médical. Nous rapportons le cas d'un homme âgé de 42ans, opéré il y a 6ans pour une sténose du bulbe duodénal d'origine ulcéreuse, il avait bénéficié d'une gastro-entéro-anastomose avec bivagotomie tronculaire. Il a été hospitalisé pour des vomissements associés à des épigastralgies. le patient a bénéficié d'une fibroscopie oeso-gastro-duodénale qui a trouvé une stase gastrique gênant toute exploration, ce qui a conduit à la réalisation d'une tomodensitométrie abdominale qui a objectivé un énorme estomac de stase en amont d'une sténose de l'anastomose gastro jéjunale, une pneumatose kystique intestinale et un pneumopéritoine. Le patient a été opéré et l'exploration a trouvé une ascite, un volumineux estomac de stase et des adhérences entre le grêle et le colon droit, sièges de la pneumatose, provoquant un tour de spire (volvulus) de l'ancienne anastomose gastro-jéjunale. L'estomac était atone. Une gastrectomie des 2/3 emportant l'ancienne anastomose suivie d'une anastomose type Finsterer manuelle a été réalisée. Les suites post opératoires étaient simples. La pneumatose kystique intestinale est une affection bénigne, de diagnostic radiologique. Le scanner permet d’étudier la diffusion des gaz dans les séreuses digestives. Son traitement est habituellement médical alors que ses complications peuvent relever d'un traitement chirurgical comme pour notre patient.

Experiments on extreme states of matter towards HIF at FAIR  

NASA Astrophysics Data System (ADS)

The Facility for Antiproton and Ion Research in Europe (FAIR) will provide worldwide unique accelerator and experimental facilities allowing for a large variety of unprecedented frontier research in extreme state of matter physics and applied science. Indeed, it is the largest basic research project on the roadmap of the European Strategy Forum of Research Infrastructures (ESFRI), and it is cornerstone of the European Research Area. FAIR offers to scientists from the whole world an abundance of outstanding research opportunities, broader in scope than any other contemporary large-scale facility worldwide. More than 2500 scientists are involved in setting up and exploiting the FAIR facility. They will push the frontiers of our knowledge in plasma, nuclear, atomic, hadron and applied physics far ahead, with important implications also for other fields in science such as cosmology, astro and particle physics, and technology. It includes 14 initial experiments, which form the four scientific pillars of FAIR. The main thrust of intense heavy ion and laser beam-matter interaction research focuses on the structure and evolution of extreme state of matter on both a microscopic and on a cosmic scale.

Evolution of fairness in the not quite ultimatum game.  

PubMed

The Ultimatum Game (UG) is an economic game where two players (proposer and responder) decide how to split a certain amount of money. While traditional economic theories based on rational decision making predict that the proposer should make a minimal offer and the responder should accept it, human subjects tend to behave more fairly in UG. Previous studies suggested that extra information such as reputation, empathy, or spatial structure is needed for fairness to evolve in UG. Here we show that fairness can evolve without additional information if players make decisions probabilistically and may continue interactions when the offer is rejected, which we call the Not Quite Ultimatum Game (NQUG). Evolutionary simulations of NQUG showed that the probabilistic decision making contributes to the increase of proposers' offer amounts to avoid rejection, while the repetition of the game works to responders' advantage because they can wait until a good offer comes. These simple extensions greatly promote evolution of fairness in both proposers' offers and responders' acceptance thresholds. PMID:24869922

THE 1996 FAIR ACT: MEASURING THE IMPACTS ON LAND LEASING  

Microsoft Academic Search

Major innovations of the 1996 FAIR Act are PFC payments and almost complete planting flexibility. Because payments are attached to the land and not production, landlords are thought to capture most of the PFC payments. With the use of a November 1997 operator survey of cropland leasing arrangements in the Mississippi Delta of Arkansas, the current study investigates changes in

Serotonin modulates striatal responses to fairness and retaliation in humans  

PubMed Central

Humans are willing to incur personal costs to punish others who violate social norms. Such ‘costly punishment’ is an important force for sustaining human cooperation, but the causal neurobiological determinants of punishment decisions remain unclear. Using a combination of behavioral, pharmacological and neuroimaging techniques, we show that manipulating the serotonin system in humans alters costly punishment decisions by modulating responses to fairness and retaliation in the striatum. Following dietary depletion of the serotonin precursor tryptophan, participants were more likely to punish those who treated them unfairly, and were slower to accept fair exchanges. Neuroimaging data revealed activations in the ventral and dorsal striatum that were associated with fairness and punishment, respectively. Depletion simultaneously reduced ventral striatal responses to fairness and increased dorsal striatal responses during punishment, an effect that predicted its influence on punishment behavior. Finally, we provide behavioral evidence that serotonin modulates specific retaliation, rather than general norm enforcement: depleted participants were more likely to punish unfair behavior directed toward themselves, but not unfair behavior directed toward others. Our findings demonstrate that serotonin modulates social value processing in the striatum, producing context-dependent effects on social behavior.

InfoFair: an annual computer and information event.  

PubMed

Since 1983, the Spencer S. Eccles Health Sciences Library has presented InfoFair, an annual event featuring presentations, exhibits, demonstrations, and workshops on computer and information topics of interest to health professionals and health information providers at the University of Utah Health Sciences Center and throughout Utah. The first InfoFair was held in response to an increasing number of inquiries from library users on how to search MEDLINE from their home or office computers. The focus of InfoFair has expanded and changed over the past nineteen years to reflect changes in library users' computer and information needs, concerns, and interests. While themes and programs have changed, a definite set of trends, guidelines, and procedures have developed based on the experience gained each year. The purpose of this paper is to review and evaluate the changes in InfoFair from 1983 to 2001 and to present information for use by other libraries for planning and presenting similar events.

Obama Boosts Science Education During White House Student Fair  

NASA Astrophysics Data System (ADS)

With the East Room of the White House flush with Nobel laureates and government officials, including freshly sworn-in U.S. National Science Foundation director Subra Suresh, President Barack Obama honored dozens of students who participated in a White House science fair on 18 October. The fair—many of whose participants have won other science, technology, engineering, and math (STEM) competitions—is part of a series of events that culminated 23-24 October in the USA Science and Engineering Festival on the National Mall in Washington, D. C., and at 50 satellite events around the country. “We welcome championship sports teams to the White House to celebrate their victories,” Obama said, noting that the Los Angeles Lakers basketball team, New Orleans Saints football team, and others have been to the White House. “I thought we ought to do the same thing for the winners of science fair and robotic contests and math competitions, because often we don’t give these victories the attention that they deserve. When you win first place at a science fair, nobody is rushing the field or dumping Gatorade over your head [in celebration].”

[Barriers to the fair allocation of healthcare resources].  

PubMed

The gap between infinite healthcare needs and finite health resources imposes on practicing physicians a dual commitment to patients' needs and to the fair allocation of health care resources. The ethical principles of a fair allocation of resources are egalitarianism, utilitarianism and a transition from individual to group-based ethics. These principles are ambiguous and occasionally conflicting. Their implementation is further impeded by practice norms, such as private practice by physicians employed by public institutions, incentives for physicians to save, and marketing of clinical interventions of unproven efficacy. Proposed approaches to these barriers to the fair allocation of resources include respect of patient autonomy with full disclosure of the limitations in the services provided by the health plan; adherence to clinical practice guidelines; and an open access for patients to second medical opinion. I believe that the fairness of resource allocation may be further improved by the prohibition of private practice by physicians employed in public health care institutions, and by enhancement of physicians' self-awareness of subconscious discrimination against some patients.

L'h?mangiome caverneux costal: une tumeur rare de la paroi thoracique  

PubMed Central

L?hémangiome caverneux de l?os est une tumeur bénigne rare; sa localisation costale est exceptionnelle. Nous rapportons le cas d?un patient de 17 ans qui consultait pour une masse pariétale. La tomodensitométrie a objectivé une tumeur de la 6e côte droite avec une rupture partielle de la corticale osseuse. Le traitement a consisté en une résection chirurgicale et l?examen microscopique de la pièce opératoire a conclu à un hémangiome costal de type caverneux. Aucune récidive n?a été notée 7 mois après l?intervention. L?hémangiome costal est une tumeur rare de la paroi thoracique. Son diagnostic de certitude est histopathologique car l'imagerie peut prêter confusion avec une origine maligne ou infectieuse.

L'acromégalie est une maladie endocrinienne rare, en rapport avec une hypersécrétion d'hormone de croissance. Elle a des conséquences rhumatologiques: l'arthropathie périphérique, l'atteinte rachidienne et les syndromes canalaires. L'atteinte articulaire accompagne une acromégalie active, sa survenue après un traitement radical et une rémission complète est rare. Nous présentons le cas d'une patiente de 70 ans ayant un antécédent d'acromégalie sur adénome hypophysaire il y a 25 ans, traitée chirurgicalement et déclarée en rémission complète, a développé une arthropathie destructrice des deux épaules. Le but de notre observation est de mettre le point sur la possibilité d'une atteinte articulaire au cours de l'acromégalie et de son retentissement fonctionnelle.

Developpement d'une methode calorimetrique de mesure des pertes ac pour des rubans supraconducteurs a haute temperature critique  

NASA Astrophysics Data System (ADS)

Le travail de recherche effectue dans le cadre de ce projet de doctorat a permis la mise au point d'une methode de mesure des pertes ac destinee a l'etude des supraconducteurs a haute temperature critique. Pour le choix des principes de cette methode, nous nous sommes inspires de travaux anterieurs realises sur les supraconducteurs conventionnels, afin de proposer une alternative a la technique electrique, presentant lors du debut de cette these des problemes lies a la variation du resultat des mesures selon la position des contacts de tension sur la surface de l'echantillon, et de pouvoir mesurer les pertes ac dans des conditions simulant la realite des futures applications industrielles des rubans supraconducteurs: en particulier, cette methode utilise la technique calorimetrique, associee a une calibration simultanee et in situ. La validite de la methode a ete verifiee de maniere theorique et experimentale: d'une part, des mesures ont ete realisees sur des echantillons de Bi-2223 recouverts d'argent ou d'alliage d'argent-or et comparees avec les predictions theoriques donnees par Norris, nous indiquant la nature majoritairement hysteretique des pertes ac dans nos echantillons; d'autre part, une mesure electrique a ete realisee in situ dont les resultats correspondent parfaitement a ceux donnes par notre methode calorimetrique. Par ailleurs, nous avons compare la dependance en courant et en frequence des pertes ac d'un echantillon avant et apres qu'il ait ete endommage. Ces mesures semblent indiquer une relation entre la valeur du coefficient de la loi de puissance modelisant la dependance des pertes avec le courant, et les inhomogeneites longitudinales du courant critique induites par l'endommagement. De plus, la variation en frequence montre qu'au niveau des grosses fractures transverses creees par l'endommagement dans le coeur supraconducteur, le courant se partage localement de maniere a peu pres equivalente entre les quelques grains de matiere supraconductrice qui restent fixes a l'interface coeur-enveloppe, et le revetement en alliage d'argent. L'interet d'une methode calorimetrique par rapport a la technique electrique, plus rapide, plus sensible et maintenant fiable, reside dans la possibilite de realiser des mesures de pertes ac dans des environnements complexes, reproduisant la situation presente par exemple dans un cable de transport d'energie ou dans un transformateur. En particulier, la superposition d'un courant dc en plus du courant ac habituel nous a permis d'observer experimentalement, pour la premiere fois a notre connaissance, un comportement particulier des pertes ac en fonction de la valeur du courant dc decrit theoriquement par LeBlanc. Nous avons pu en deduire la presence d'un courant d'ecrantage Meissner de 16 A, ce qui nous permet de determiner les conditions dans lesquelles une reduction du niveau de pertes ac pourrait etre obtenue par application d'un courant dc, phenomene denomme "vallee de Clem".
