    2017-07-01

    Full Text Available Le présent article de revue concerne des acquisitions récentes dans le domaine de l’electrophysiologie des cellules productrices d’insuline. D’abord, dans le cadre de la participation des canaux anioniques sensibles au volume cellulaire, en particulier l’anoctamine 1, au processus de stimulation de la sécrétion d’insuline par le glucose, les modifications de l’activité bioélectrique de cellules insulaires soumises à l’hexose provoquées par l’acide tannique sont exposées. Les modifications du potentiel de membrane provoquées par la carbamylcholine en présence d’une concentration physiologique de glucose sont ensuite prises en considération. Enfin, l’accent est mis sur les aspects bioélectriques de l’activation par le sucralose du récepteur au goût sucré TIR 3 présent dans les cellules productrices d’insuline. Les implications physiopathologiques d’une telle activation sont également évoquées.

    The geometry and the technology of a cell used for investigations on electron-adsorbed gas interactions are described. The resonance frequencies of the surface ions which are created by the electron impact on the adsorbed gas are predicted by simplified calculations. The experimental data relative to carbon monoxide and neon are in good agreement with these predictions.

    : par l'un des modes d'induction d'une letalite dominante, par l'inactivation directe d'une fonction et par des manieres genetiquement indefinissable, liees ou non a la letalite dominante. Les agents chimiques de mutation paraissent egalement provoquer un accroissement curieux du pouvoir fertilisant du sperme. La radiosensibilite varie avec les divers stades de l'oogenese et de la spermatogenese; certaines cellules passent par des stades au cours desquels leur radiosensibilite peut varier dans un rapport de 1 a 50. Des comparaisons entre des diptetes, des hymenopteres et des coleopteres ont revele une similarite frappante dans la maniere dont ces especes reagissent aux rayonnements, tant en ce qui concerne la sensibilite aux divers stades de developpement que l'intensite de la reaction en fonction de la dose. Le ver a soie Bombyx mori (lepidoptere) semble avoir beaucoup de points communs avec les representants des autres ordres en ce qui concerne l'effet des rayonnements sur les cellules germinales, mais il en differe nettement pour ce qui est des facteurs letaux dominants induits. Les especes presentant des mecanismes genetiques anormaux (par exemple, le Planococcus citri, coccide hemiptere) constituent des cas particuliers et ils reagissent aux rayonnements de facon tres differente des autres especes. Dans la lutte contre les insectes par la methode de Tirradiation des males, la letalite dominante est aussi efficace pour les especes ou l'accouplement a lieu plusieurs fois que pour celles ou il a lieu une seule fois. On peut considerer l'inactivation du sperme et la destruction des cellules des gonades comme des facteurs de sterilite reelle; leur efficacite est maximum chez les especes ou l'accouplement n'a lieu qu'une seule fois. Pour le controle le plus efficace, il faudrait avoir recours a des doses provoquant la letalite dominante maximum, l'inactivation minimum du sperme et la destruction totale des cellules des gonades. Il est facile de determiner ces parametres

  10. Faut-il faire la sociologie des singes ?

    Véronique Servais

    2012-05-01

    Full Text Available En prenant appui sur des exemples empruntés à l’éthologie sociale, ce texte apporte trois arguments au débat sur la naturalisation du social. Le premier met en question la notion de compétence sociale innée en insistant sur la nécessité de préciser « ce qui » est (ou pourrait être inné dans une compétence sociale. Le deuxième montre que la négligence de la dimension affective des interactions et de la communication animale a pour conséquence de placer dans les esprits animaux des « délibérations » ou des « calculs » qui sont d’abord une propriété de la communication affective. Le troisième examine quelques travaux récents sur la coopération chez les primates et conclut qu’ici aussi, les biologistes oublient qu’une grande partie des compétences sociales qu’ils situent dans les individus relèvent en fait de la situation. Après avoir ainsi exposé les limites et les impasses de la biologie dans l’explication du social, y compris dans le monde animal, le texte propose que les sciences sociales investissent empiriquement ce champs laissé en friche, celui de l’articulation entre le biologique et le social. Elles pourraient ainsi contribuer à mieux circonscrire « ce qui » est inné et, donc, à limiter objectivement les ambitions évolutionnistes sur le social.Should we do Sociology of Monkeys?Drawing its examples from the field of ethology and primatology, this paper brings three points to the debate on the naturalization in sociology. The first one insists on the importance of telling apart what is innate and what is not in the “innate social abilities” that are hypothesized by Kaufmann & Cordonier. The second one shows that when scientists see the animal communication as purely informative, they miss the fact that animals are first of all real beings engaged in affective interactions. They consequently wrongfully end up with animals that “calculate” or “make choices”. The third

    Full Text Available Depuis plusieurs années, nous étudions les mécanismes moléculaires responsables de la fusion du virus de l’immunodéficience humaine (VIH avec la membrane plasmique des cellules cibles. Ces travaux ont permis de préciser le rôle essentiel joué par les micro-domaines de glycosphingolipides au cours de la fusion virus-cellule. En particulier, nous avons pu reconstituer un complexe de fusion fonctionnel faisant intervenir les différents partenaires moléculaires de la fusion : un micro-domaine de glycosphingolipide se présentant sous la forme d’un film monomoléculaire à l’interface eau-air, le récepteur CD4 et la glycoprotéine externe de l’enveloppe du virus, la gp120. La dynamique des interactions moléculaires dans ce complexe de fusion a pu être mesurée à l’aide d’un micro-tensiomètre. Ce système expérimental pourrait permettre d’évaluer l’activité d’inhibiteurs de fusion tels que des analogues synthétiques de glycosphingolipides.

    Full Text Available A universal dimensionless scaling group and its critical value at the onset of instability for a miscible displacement in a Hele-Shaw cell is derived. The derivation is based on a variational technique and it is capable of considering, for the first time, the effect of the length of a Hele-Shaw cell on the criterion for the onset of instability. The theory is verified by comparing it with forty-four Hele-Shaw cell experiments. On calcule un groupe universel sans dimension de mise à l'échelle et sa valeur critique au départ de l'instabilité dans un déplacement miscible dans une cellule Hele-Shaw. Ce calcul est basé sur une technique variationnelle et permet, pour la première fois, de prendre en compte l'effet de la longueur d'une cellule Hele-Shaw sur le critère d'apparition d'instabilité. La théorie est vérifiée en la comparant avec des expériences réalisées avec quarante-quatre cellules Hele-Shaw.

    Labelled blood cells permit nuclear medicine imaging using their physiological behaviours. The radiolabeling must be performed in vitro because of the lack of specific markers and requires several highly technical stages of preparation. Labelled blood cells have not the medication drug status, so that the nuclear physician conducting the nuclear test is fully liable. In most cases, the physician delegates the technical responsibility to radio-pharmacists. Although the status of radiolabelled autologous cells is not legally defined and in the absence of a specific repository, it is essential that their preparation is subject to the requirements of the rules of French Good Manufacturing Practice published by Agence francaise de securite sanitaire des produits de sante (Afssaps). It would be desirable to harmonize the practices of radiolabeling cellular blood components by editing a repository. (authors)

  18. Material influence on biocontamination level and adhering cell physiology Influence des matériaux sur le niveau de biocontamination et la physiologie des cellules adhérentes

    2013-11-01

    Full Text Available Dans la plupart des environnements, les microorganismes vivent préférentiellement au sein de biofilms. De nombreux facteurs influencent leur formation i.e. les nutriments, la température, le régime du fluide environnent, la microflore et les matériaux. Dans le mécanisme de biocontamination, décrit en quatre étapes successives, l'adhésion initiale est un élément clé de la bioadhésion et les matériaux un élément majeur pour son contrôle. L'acier inoxydable est très utilisé dans de nombreux secteurs d'activité pour sa bonne nettoyabilité et son excellente résistance à la corrosion. Pour se différencier, certains matériaux mettent en avant d'autres propriétés. Ainsi, la sélection du matériau le mieux adapté à un problème donné nécessite de connaitre son aptitude à la biocontamination ainsi que son impact sur la physiologie des microorganismes. Pour tous les matériaux testés, la mortalité des bactéries adhérentes est inférieure à 55 %. Les résultats obtenus ont montré qu'un matériau dit antimicrobien n'induit pas plus de cellules endommagées comparativement aux autres matériaux. In most environments, association with a surface in a structure known as a biofilm is the prevailing microbial lifestyle. Several factors may influence the biofilm formation e.g. nutrients, temperature, flow velocity, initial microflora and the nature of materials. Considering the biocontamination mechanism described in four steps, the initial adhesion is a key element in the biocontamination phenomenon and the substratum is of major concern in controlling bacterial adhesion. Stainless steel is well used in numerous markets because of its high cleanability and corrosion resistance properties. However, other materials are put forward by focusing on properties which differentiate them from those of stainless steel. Thereby, to select the material best suited to the problem, there should have data on their aptitude for

    The main studies and experiments involved in the development of a cell-assembly for the treatment of irradiated fuels on a semi-industrial scale are described. It must be possible to modify or transform each of these cells without interrupting the rest of the pilot. A full-scale prototype cell (3 x 4 x 6 m) has been built with an {alpha}-protection independent of the {gamma}-protection. It features all the main characteristics: tightness to {gamma} losses, dense glass lighting, ventilation. This cell has made possible trials on transfer, remote-controls and tele-dismantling, as well as the development of new methods of rapidly connecting hydraulic circuits. In conclusion the final form is given of the cells selected for the pilot.

  3. Ethischer Konsum vs. Konsumreduktion: Inwieweit lenkt Fair Trade vom Problem des Überkonsums ab?

    Susanna Ulinski

    2013-09-01

    Full Text Available This essay explores the alleged trade-off between reducing overconsumption and promoting ethical consumption, especially in the form of Fair Trade. While Fair Trade is primarily concerned with promoting greater equity in international trade, it does not address problems of ecological exhaustion through overconsumption. Furthermore, Fair Trade could promote increased consumption by inducing false consciousness among consumers. In this context, I propose an integrative approach of trying to address these two problems simultaneously by changing the social patterns of consumption, instead of interpreting them as diametrically opposed. Awareness is the first step in inducing a behavioural change. On an individual level, Fair Trade is fairly successful at creating sensational feedback processes, which increase the awareness for the social and environmental implications of individual consumer behaviour. Moreover, on an aggregate level, Fair Trade changes social patterns of consumption to promote ethical consideration in the context of consumer decision-making. Although Fair Trade is not primarily concerned with the level of consumption, it can help bring forth a change in consumption patterns in order to reduce overconsumption.

    Rescigno, J.; McCormick, B.; Brown, A.E.; Myskowski, P.L.

    1994-01-01

    Cellulitis is a previously unreported complication of conservative surgery and radiation therapy for early stage breast cancer. Patients who presented with breast cellulitis after conservative therapy are described. Eleven patients that developed cellulitis of the breast over a 38-month period of observation are the subject of this report. Clinical characteristics of patients with cellulitis and their treatment and outcome are reported. Potential patient and treatment-related correlates for the development of cellulitis are analyzed. The risk of cellulitis persists years after initial breast cancer therapy. The clinical course of the patients was variable: some patients required aggressive, long-duration antibiotic therapy, while others had rapid resolution with antibiotics. Three patients suffered from multiple episodes of cellulitis. Patients with breast cancer treated with conservative surgery and radiotherapy are at risk for breast cellulitis. Systematic characterization of cases of cellulitis may provide insight into diagnosis, prevention, and more effective therapy for this uncommon complication. 15 refs., 1 fig., 2 tabs

    2012-01-01

    Full Text Available Les rapports entre l’économie et les autres sphères de la société sont en train de se transformer, et avec eux, les expressions de la solidarité et les modèles d’engagement. Parmi eux, les alliances entre acteurs hétérogènes (entreprises, ONG et « social business », pouvoirs publics, acteurs de l’Internet, etc. permettent de s’attaquer aux grands enjeux de ce monde avec davantage de justesse et d’efficacité. En agrégeant des acteurs aux logiques différentes dans une dynamique de co-création, les alliances ouvrent de nouveaux horizons de développement. Avec la Clinton Global Initiative, Bill Clinton s’est donné comme objectif d’encourager les alliances sur des actions généreuses qui soient efficaces et mesurables. Si la dynamique fonctionne dans le monde anglo-saxon, elle peine à s’installer en Europe. Pourtant les acteurs européens disposent de nombreux atouts pour s’engager dans de nouvelles alliances transformatrices de notre monde et auraient tout intérêt, pour ce faire, à se fédérer. Plusieurs membres européens de la Clinton Global Initiative ont ainsi lancé le réseau « The European Network » pour amorcer un mouvement en Europe et donner une ambition européenne à l’engagement sociétal. Cet article décrit les singularités des alliances avant de présenter la structuration de l’action européenne en relation avec la Clinton Global Initiative.

    Dose effect relations concerning inhibition of clone formation by kidney cells of human origin in culture after irradiation with monoenergetic neutrons of about 3-MeV and about 15-MeV energy, are reported. For 3-MeV neutrons the dose rate was equal to 0.2 rad/min, while for 15-MeV neutrons dose rates of 2.7 rad/min and 12 rad/min were obtained. The cells were irradiated in culture dishes with a thin Melinex bottom and in small flexible nylon and silicon rubber tubes. Neutron fluxes were determined by measuring the activation of sulphur pellets mounted respectively between the dishes and the tubes. Calculation of the dose on the basis of the neutron flux presented a number of problems which are discussed. Because no radiation equilibrium exists around the cells, the resulting inaccuracies in the dose determinations are investigated. Dose-survival curves for both types of neutrons are presented. For 3-MeV neutrons an RBE was found ranging from 6.5 at low doses to about 3.1 at high doses, while for 15-MeV neutrons the RBE varied from 1.9 to 1.6. By comparison of these RBE-values with the RBE-LET relation obtained in earlier experiments with deuterons and {alpha}-particles, it is possible to derive an effective LET for the neutrons used. In order to elucidate certain problems related to the death of experimental animals after X- or neutron- irradiation, a technique has been developed whereby the cells, contained in small tubes, are used to measure the effective dose (i.e . dose corrected for the RBE) at sites of interest in phantoms or animals. (author) [French] Les auteurs indiquent les relations dose-effet pour l 'inhibition de la formation de lignees par les cellules renales d' origine humaine apres irradiation par des neutrons monoenergetiques de 3 MeV et de 15 MeV.

    Full Text Available Sporotrichosis is a cutaneous or systemic fungal infection caused by Sporothrix schenckii. The infection is characterized by nodular, pustular, or ulcerative lesions. Infection usually occurs after traumatic implantation of the fungus into the skin. We report a case presenting first cellulitis and later on as a non-healing ulcer which was diagnosed by punch biopsy as sporotrichosis and managed successfully with itraconazole. A 56-year-old woman admitted to our department with complaint acute onset of swelling of the right lower-extremity with erythema and warmth. The patient was diagnosed initially as celulitis and started on ampicillin-sulbactam. Diagnosis of sporotrichosis was made with histological examination skin biopsy and the patient was started on itraconazole. One month after commencement of antifungal treatment, the ulcer began to dry up and at 3 months the lesions had healed. This case shows that if a wound do not respond to antibiotics in cases with ulcer, some rare etiological agents should be considered. [Dis Mol Med 2016; 4(3.000: 34-36

    The elementary diffusion equation and the age equation have been solved for lattices assumed, to be infinite and periodic. In this way the influence of the form of the cells on thermal captures and resonance captures is determined. The solutions obtained are expressed by means of tabulated functions which can be used in the analysis of the f factor measurements. The case of mixed lattices in which different types of rods are regularly arranged is also foreseen. (author) [French] L'equation elementaire de la diffusion et l'equation de l'age ont ete resolues pour des reseaux supposes infinis et periodiques. On determine ainsi quelle est l'influence de la forme des cellules sur les captures thermiques et les captures de resonances.

    Full Text Available Avec le roman Salammbô et le conte Hérodias, Flaubert se tourne vers l’Antiquité préchrétienne afin de montrer à la modernité, sur le mode « clair et vif », sa complexité, son implication dans des discours de pouvoir religieux et historiographiques. C’est en se penchant sur les sources historiographiques et bibliques que Flaubert décline les stratégies d’exclusion et de surécriture, mettant au jour ce qu’elles refoulent, non pas sous forme de signification alternative, explicite, mais en tant que défiguration, réalisation littérale des corps et des signes.Avec Salammbô, Flaubert écrit une histoire du salut. Carthage, représentée dès le début par la protagoniste Salammbô en tant que pars pro toto, expose les figures cachées de Rome, à laquelle est liée, aussi et surtout, la promesse chrétienne de salut. Dans le nom de Salammbô Flaubert réécrit l’origine de cette figure en fait associée à la Rome chrétienne en s’appuyant sur l’exemple de l’histoire antique de Carthage.Dans Hérodias, Flaubert reprend le thème du triomphe de l’Orient annoncé par Renan et redouté par l’Église catholique. Un danger, pourrait-on dire, qui se réalise dans la figure d’Hérodias et qui est conjuré avec la décapitation de Jean. Dans son rapport inversé avec les textes de référence, Hérodias démasque les ambitions et la volonté hégémonique du modèle de pouvoir propre à l’Église en Orient. La translatio de l’empire romain est radicalisée au moyen de la figure d’Aulus. Aulus peut faire l’objet d’une lecture performative en tant que début et fondement de l’histoire française du salut comme histoire romaine de la perversion.In the novel Salammbô and the short story Hérodias, Flaubert turns to pre-Christian antiquity in order to present modernity its complexity, its entwinement in religious and historiographical discourses of power, in a « clair et vif » manner.

    avantages que presente l'emploi de composes trities pour l'autoradiographie. En effet les electrons du tritium ont une energie maximum de 0,018 MeV, correspondant a un parcours d'environ 1 micron dans une emulsion photographique, ce qui permet d'obtenir le plus fort degre de resolution possible aux niveaux cellulaire et infracellulaire. Ce phenomene est particulierement utile pour l'etude du metabolisme de tissus comme la moelle osseuse, qui sont composes de differents types de cellules a divers stades de differenciation. Cette technique a ete utilisee pour l'etude du metabolisme des acides nucleiques et des proteines des cellules normales et leucemiques de la moelle osseuse. L'auteur a etudie le metabolisme de l'ADN a l'aide d'un precurseur specifique, la thymidine tritiee. Il a decele certaines differences importantes dans les pourcentages de cellules marquees, en comparant les elements normaux et leucemiques au meme stade de maturation. Il a constate, en particulier, que dans les cellules d'un sujet atteint de leucemie aiguee, le taux d'incorporation de la thymidine etait beaucoup plus faible, ce qui prouve une diminution de la capacite de proliferation de ces cellules par rapport aux myeloblastes normaux. L'auteur a utilise la meme technique pour etudier le metabolisme de l'ARN et des proteines, a l'aide des precurseurs suivants: uridine, leucine et phenylalanine tritiees. Il est maintenant admis en biologie cellulaire qu'il existe un rapport etroit entre le metabolisme de l'ARN et celui des proteines; l'auteur a demontre qu'il existait egalement un rapport constant entre l'incorporation de l'uridine et des acides amines, dans les cellules normales de la moelle osseuse. Dans les cellules de sujets atteints de leucemie aiguee, l'incorporation de l'ARN et des precurseurs protidiques, bien qu'elle differe dans chaque cas, est toujours nettement plus faible. De plus, le rapport entre l'incorporation de l'uridine et celle des amino-acides varie constamment dans ces cellules

    Satish R Patil

    2013-01-01

    Full Text Available Bacteria of the genus Salmonella are highly adapted for the growth in both humans and animals and cause a wide spectrum of disease. The growth of Serotypes S. typhi and S. paratyphi is restricted to human hosts, in whom these organisms cause enteric (typhoid fever. The remaining Serotypes (non typhoidal Salmonella or NTS can colonize the gastrointestinal tracts of the broad range of animals, including mammals, reptiles, birds and insects. The usual clinical presentation of non-typhoidal salmonellae (NTS infection is self limited gastroenteritis; however bacteremia and focal extra intestinal infection may occur. However salmonella localization to the skin presenting as cutaneous ulceration is regarded as a rare event. Rates of morbidity and mortality associated with NTS are highest among the elderly, infants, and immunocompromised individuals, including those with hemoglobinopathies, HIV infection, or infections that cause blockade of the reticuloendothelial system. We isolated S.infantis in 50 years old man with left leg cellulitis. The serotype was confirmed at Central Research Institute, Kasauli.

    Full Text Available Cette contribution, qui porte sur un emploi spécifiquement locutionnel de l’infinitif dans le contexte de la presse écrite francophone, aborde plus particulièrement les usages de ce type d’expression dans les journaux quotidiens. C’est donc comme construction grammaticale, mais aussi comme formule spécifique insérée dans le discours journalistique qu’est envisagé ici l’infinitif de narration, dont l’emploi, quelquefois abondant dans notre corpus, place les démarches citationnelles des écrits de presse dans une mise en scène des propos rapportés. Par ailleurs, cet emploi révèle à bien des égards, dans le cadre cette fois-ci de la répartition entre discours citant et discours cité, un enchérissement, voire une intensification de l’événement d’énonciation, en arrière-plan d’une évidente tonalité polémique.La première partie de cette contribution présente de manière sommaire ce qu’est l’infinitif de narration sur le plan linguistique, tout en revenant sur les invariants qui le caractérisent. La deuxième partie traite des apports de ce type d’expression verbale dans le cadre des formes de textualité du journal quotidien. Dans la troisième partie, l’infinitif de narration est envisagé comme un élément rédactionnel singulier, une variable significative de la citation journalistique.This contribution deals with a specific use of the infinitive in the context of the French-speaking print media, and more particularly common representations of this type of expression in the daily newspapers. We are thus dealing here with the “narrative infinitive” as a grammatical construction, but also as a specific formula of media speech. According to our corpus, this use indicates how journalistic drafting stages the fact, in other words places it in a reconstruction, with intensification of the event, underlying a clearly polemical tone.The first part of this article presents the infinitive of narration

    Full Text Available A prospective study of diagnostic techniques in cellulitis was performed on 28 patients with malignancy. Twenty-two (78% of the fine needle aspiration cultures and 10 (35% of the blood cultures were positive in this immunocompromised population. The incidence of positive fine needle aspiration cultures (P<0.005 or bacteremia (P<0.0005 was significantly higher than results obtained in an immunocompetent population with cellulitis at the same institution. Staphylococci or streptococci were recovered in 59% of positive cultures, while aerobic Gram-negative bacilli grew in 33%. This study indicates that in the immunocompromised population with cellulitis, fine needle aspiration and blood cultures should be obtained, and the antibiotic regimen should cover Gram-positive cocci and Gram-negative bacilli pending the results of cultures.

Further, the incorporation pattern was the same whether the label was added at the beginning of the incubation or after 160 min. Addition of TH{sup 3} to the same suspension at various time intervals did not alter the per cent of labelled cells but the number of grains per nucleus rose after every administration of the TH{sup 3}. Not all the cells in the suspension incorporated the same amount of TH{sup 3}. Quantitative measurements were made including grain counts, and the results showed that there is probably a deficiency of thymidine available to the leukaemic cells in their ascitic fluid. The dichotomy between the synthesis of the full complement of DNA and subsequent division of the cell will be discussed.

    Full Text Available Bergeyella zoohelcum is a rod-shaped, aerobic, Gram-negative, non-motile and non-saccharolytic bacterium. It is frequently isolated from the upper respiratory tract of dogs, cats and other mammals. Clinically, B. zoohelcum has been known to cause cellulitis, leg abscess, tenosynovitis, septicemia, pneumonia and meningitis, and is associated with animal bites. In addition, food-borne transmission was considered in a recent case report. We report a 73-year-old man with liver cirrhosis who had no history of dog bite but had dog exposure, who developed cellulitis of the left lower leg and B. zoohelcum was isolated from blood culture. This patient, without evidence of polymicrobial infection, was treated with cefazolin and gentamicin with a good outcome. B. zoohelcum is a zoonotic pathogen that may cause bacteremia in patients with underlying disease such as liver cirrhosis; it can be treated with a beta-lactam or quinolone.

  12. Dynamique de nanobulles et nanoplasmas generes autour de nanoparticules plasmoniques irradiees par des impulsions ultracourtes

    Dagallier, Adrien

    L'emergence des lasers a impulsion ultrabreves et des nanotechnologies a revolutionne notre perception et notre maniere d'interagir avec l'infiniment petit. Les gigantesques intensites generees par ces impulsions plus courtes que les temps de relaxation ou de diffusion du milieu irradie induisent de nombreux phenomenes non-lineaires, du doublement de frequence a l'ablation, dans des volumes de dimension caracteristique de l'ordre de la longueur d'onde du laser. En biologie et en medecine, ces phenomenes sont utilises a des fins d'imagerie multiphotonique ou pour detruire des tissus vivants. L'introduction de nanoparticules plasmoniques, qui concentrent le champ electromagnetique incident dans des regions de dimensions nanometriques, jusqu'a une fraction de la longueur d'onde, amplifie les phenomenes non-lineaires tout en offrant un controle beaucoup plus precis de la deposition d'energie, ouvrant la voie a la detection de molecules individuelles en solution et a la nanochirurgie. La nanochirurgie repose principalement sur la formation d'une bulle de vapeur a proximite d'une membrane cellulaire. Cette bulle de vapeur perce la membrane de maniere irreversible,entrainant la cellule a sa mort, ou la perturbe temporairement, ce qui permet d'envisager de faire penetrer dans la cellule des medicaments ou des brins d'ADN pour de la therapie genique. C'est principalement la taille de la bulle qui va decider de l'issue de l'irradiation laser. Il est donc necessaire de controler finement les parametres du laser et la geometrie de la nanoparticule afin d'atteindre l'objectif fixe. Le moyen le plus direct a l'heure actuelle de valider un ensemble de conditions experimentales est de realiser l'experience en laboratoire,ce qui est long et couteux. Les modeles de dynamique de bulle existants ne prennent pas en compte les parametres de l'irradiation et ajustent souvent leurs conditions initiales a partir de leurs mesures experimentales, ce qui limite la portee du modele au cas pour

  13. Endodontic cellulitis 'flare-up'. Case report.

    Matusow, R J

    1995-02-01

    Endodontic cellulitis involves facial swelling which can vary from mild to severe and can occur as a primary case or a flare-up following initial treatment of asymptomatic teeth with periapical lesions. The microbial spectrum in primary cases involves a significant mixture of anaerobic and facultative aerobic microbes, chiefly streptococci. In a previous study, cultures from flare-up cases, utilizing the same anaerobic techniques as in primary cases, revealed an absence of obligate anaerobes and an 80 per cent incidence of facultative aerobic streptococci. These cases also revealed a significant time lapse from onset of symptoms to the cellulitis phase. No sex or age factors were noted in the primary or flare-up cases. The purpose of this case report is to restate a traditional theory, namely, the alteration of the oxidation/reduction potential (Eh), as a major factor for endodontic cellulitis flare-ups; to confirm the pathogenic potential of oral facultative streptococci; and that asymptomatic endodontic lesions tend to exist with mixed aerobic/anaerobic microbial flora.

En opérant un retour sur le déroulement d’une enquête ethnofilmique menée auprès des dinandiers de la médina de Fès, cet article s’interroge sur ce qui est initialement apparu comme une contradiction : les travailleurs ont tous accepté la présence de l’ethnologue-cinéaste et de sa caméra dans leurs ateliers, mais ils ne s’impliquaient pas lors des entretiens prenant appui sur les films. Ce texte offre un éclairage sur les décalages pouvant exister entre les discours de ces artisans et la réalité sociotechnique de leur condition, tout en présentant une réflexion sur certaines caractéristiques d’une méthode de recherche ethnographique fondée sur une pratique cinématographique. Afin de s’accommoder d’une situation qu’ils rejettent, les artisans reprennent les termes d’un discours patrimonial idéalisant une réalité socio-économique ; le contexte du travail favorise l’établissement d’une forme de coopération originale entre filmant et filmés ; le refus de procéder à un échange de vues prenant appui sur les films peut être productif dans la compréhension d’un objet de recherche.Filming, demonstrating and hearing know-how.

    The localisation of {beta}-indolylacetic acid (A.I.A.), a growth auxin is attempted using nuclear indicators ({sup 14}C and tritium). The radio - auto-histographic detection method depends on the insolubilization of A.I.A. 'in situ' by picric acid and basic lead acetate at a suitable pH, the A.I.A. being protected from histological solvents. The results of the detections corresponding to physiological responses during growth tests on Pisum, Avena, Phascolus and Vicia, at concentrations of 10{sup -5} and higher make possible the localisation of tissues in agreement with the auxinic activity and with the relations already known between A.L.A. and cellular formations. By increasing the time of exposures of the sections, it will be possible to attain concentrations which are much lower and more clearly physiological. (authors) [French] La localisation de l'acide {beta}-indolylacetique (A.L.A.), auxine de croissance est abordee avec les indicateurs nucleaires ({sup 14}C et tritium).

    Siregar, R. S.; Daulay, K. R.; Siregar, B.; Ramayani, O. R.; Eyanoer, P. C.

    2018-03-01

    Nephrotic syndrome is a chronic disease that may act as a risk for other major infection in skin, respiratory and urinary tract, while also increasingthe chance for other diseases, like peritonitis, meningitis, and cellulitis. Cellulitis is often caused by Streptococcus β-hemolytic, Staphylococcus aureus, and Escherichia coli. The clinical features of cellulitis marked with redness rash and well-defined borders, pain pressure and swelling. Hypoalbuminemia which occurs due to proteinuria occurred in this patient acts as a risk factor for cellulitis. It has been reported the case of cellulitis as one of the complications of the nephrotic syndrome in the pediatric patient. The treatment has been given to the patient such as antibiotics and supportive therapy and also planned albumin substitution.

    Orbital cellulitis is a severe and sight-threatening infection of orbital tissues posterior to the orbital septum. The most common causes of orbital cellulitis are rhinosinusitis, orbital trauma, and surgery. Infective endocarditis (IE) is a systemic infection that begins on cardiac valves and spreads by means of the bloodstream to peripheral organs. Septic emboli can spread to any organ including the eyes and can cause focal or diffuse ophthalmic infection. Ocular complications of IE classic...

  2. Faire du business au bas de la pyramide : la réalité des marches émergents

    Full Text Available Le rôle du business a été traditionnellement ignoré dans les débats internationaux portant sur le développement économique et la lutte contre la pauvreté. Toutefois, le succès mondial récent du secteur de la téléphonie mobile et son essor rapide sur les marchés émergents au cours des deux dernières décennies ont imposé une remise en question. Au lieu de stratégies de développement descendantes, orientées sur l’aide, les débats portent à présent davantage sur la fourniture de biens et de services rentables à la base de la pyramide économique (BOP, comme le font les entreprises de téléphonie mobile. Des équipes de recherche du CEMS (Centre for Emerging Markets Solutions  ont découvert que, bien qu’il soit possible de desservir de façon rentable les marchés BOP, cela exige de s’écarter des stratégies préconisées dans les publications ordinaires sur la BOP. Cette approche oblige notamment à aborder des questions liées au climat macroéconomique et commercial du pays, aux erreurs d’appréciation du risque, à l’esprit d’entreprise. Elle implique également une réorientation, afin de s'éloigner des multinationales et de se rapprocher du secteur des petites entreprises, avec les coûts de transaction qui le minent. Ce document examine également quelques modèles d’entreprise durables qui ont fonctionné sur ces marchés et analyse quelques secteurs que les capitaux commerciaux trouveront extrêmement intéressants et dignes d’investissements. Enfin, nous étudierons comment structurer et exploiter les énormes opportunités commerciales générées par le traitement du manque d'organisation des marchés BOP, à l’aide d’une combinaison de modèles d’entreprise innovants (en particulier autour de structures à coût réduit, de recherche, d’esprit d’entreprise et de capitaux patients.

  3. Impact de la preparation des anodes crues et des conditions de cuisson sur la fissuration dans des anodes denses

    Amrani, Salah

    La fabrication de l'aluminium est realisee dans une cellule d'electrolyse, et cette operation utilise des anodes en carbone. L'evaluation de la qualite de ces anodes reste indispensable avant leur utilisation. La presence des fissures dans les anodes provoque une perturbation du procede l'electrolyse et une diminution de sa performance. Ce projet a ete entrepris pour determiner l'impact des differents parametres de procedes de fabrication des anodes sur la fissuration des anodes denses. Ces parametres incluent ceux de la fabrication des anodes crues, des proprietes des matieres premieres et de la cuisson. Une recherche bibliographique a ete effectuee sur tous les aspects de la fissuration des anodes en carbone pour compiler les travaux anterieurs. Une methodologie detaillee a ete mise au point pour faciliter le deroulement des travaux et atteindre les objectifs vises. La majorite de ce document est reservee pour la discussion des resultats obtenus au laboratoire de l'UQAC et au niveau industriel. Concernant les etudes realisees a l'UQAC, une partie des travaux experimentaux est reservee a la recherche des differents mecanismes de fissuration dans les anodes denses utilisees dans l'industrie d'aluminium. L'approche etait d'abord basee sur la caracterisation qualitative du mecanisme de la fissuration en surface et en profondeur. Puis, une caracterisation quantitative a ete realisee pour la determination de la distribution de la largeur de la fissure sur toute sa longueur, ainsi que le pourcentage de sa surface par rapport a la surface totale de l'echantillon. Cette etude a ete realisee par le biais de la technique d'analyse d'image utilisee pour caracteriser la fissuration d'un echantillon d'anode cuite. L'analyse surfacique et en profondeur de cet echantillon a permis de voir clairement la formation des fissures sur une grande partie de la surface analysee. L'autre partie des travaux est basee sur la caracterisation des defauts dans des echantillons d'anodes crues

  6. Development of a digital high-frequency regulation for the pulsed operation of the proton-linac test facility at FAIR; Entwicklung einer digitalen Hochfrequenzregelung fuer den gepulsten Betrieb des Protonenlinac Teststandes bei FAIR

    Nonn, Patrick Walter

    2014-06-16

    At the site of the GSI Helmholtzzentrum fuer Schwerionenforschung near Darmstadt, the international Facility for Antiproton and Ion Research (FAIR) is under construction. The research program of FAIR includes experiments with antiproton beams. In order to provide the high intensity proton beam, that is necessary to produce the antiprotons, a new linear accelerator, acting as injector to the SIS18 synchrotron, will be constructed. This linear accelerator, called p-Linac, shall be kept as short as possible. That is why novel CH-type cavities will be used for the main acceleration from 3 MeV to 70 MeV. In order to test these novel cavities and their supporting technology, an rf test stand is under construction at GSI. Within the scope of this thesis a pulsed 325 MHz control system has been developed as part of that test stand. It is based upon the cw rf control system of the superconducting Darmstaedter Linearaccelerator (S-DALINAC), that is designed to drive normal- and superconducting cavities at 3 GHz. Aim of this thesis is, to adapt the frequency of S-DALINAC's rf control to p-Linac's 325 MHz at one hand and on the other hand, to improve the response time in order to achieve a relative amplitude error of below 10{sup -3} and a phase error below 0.1 within the 200 μs long rf pulses. The time that is needed in order to re-achieve the errors after the beam pulse hits the cavity, is also crucial. At first, the dependance of the control rate to various parameters of the cavity and the control has been tested by analytical and numerical methods. Therefore, the behavior of a cavity's amplitude in the base band has been modeled and confirmed by comparison of the model's and a measured step response of a cavity. The dependance of the I- and PI-control's parameters on the decay time of the cavity was shown by analytical methods. With the aid of numerical simulations the extent at which the response time is affected negatively by dead time and

    The aim of this study was to assess the use of magnetic resonance as a new method for evaluating the manual lymphatic drainage technique in treating cellulitis. Cellulitis is one of the main esthetic problems that lead women toward seeking guidance and specific treatments. There are various therapeutic approaches, owing to the multifactorial nature of its pathogen, although the effectiveness of most of these has not been definitively proven, given that the assessment methods used are mostly subjective or do not provide enough information on subcutaneous tissue. The introduction of magnetic resonance as a means of assessing a lymphatic drainage technique in cellulitis treatment makes the evaluation more accurate, since it enables a detailed study of subcutaneous architecture.

    Full Text Available The flood after a typhoon may lead to increase in patients with cellulitis of lower limbs. However, the microbiological features of these cases are rarely reported. We conducted a study of patients with lower extremity cellulitis after a typhoon followed in southern Taiwan to study the risk factors of cellulitis and the bacteriological features of the patients.We reviewed all the medical records of cellulitis at emergency departments of two teaching hospitals in southern Taiwan 30 days before and after the landing of Typhoon Morakot and collected data on the demographic and bacteriological characteristics. In addition, we evaluated the relationship between the daily number of patients and the rainfall in the Tainan area.The number of cellulitis patients increased from 183 to 344 during the 30-day period after the typhoon. The number peaked in the third and fourth days and lasted for 3 weeks. The proportion of patients with water immersion of the affected limb was higher after the typhoon (6% vs. 37%, odds ratio [OR]: 9.0, 95% Confidence interval [CI]: 4.7-17.2. We found cultures from the infected limbs with immersion had more polymicrobial (73% vs. 26%, OR: 7.8, 95% CI: 3.2-19.2 and Gram-negative bacilli infection (86% vs. 34%, OR: 11.8, 95% CI: 4.1-34.5.Flood arose from Typhoon Morakot caused increases in cellulitis patients, which lasted for 3 weeks. Antibiotic treatment that were effective to both Gram-positive cocci and Gram-negative bacilli are recommended for patients with limbs emerged in the water.

  13. Fair innings.

    Bognar, Greg

    2015-05-01

    In many societies, the aging of the population is becoming a major problem. This raises difficult issues for ethics and public policy. On what is known as the fair innings view, it is not impermissible to give lower priority to policies that primarily benefit the elderly. Philosophers have tried to justify this view on various grounds. In this article, I look at a consequentialist, a fairness-based, and a contractarian justification. I argue that all of them have implausible implications and fail to correspond to our moral intuitions. I end by outlining a different kind of consequentialist justification that avoids those implications and corresponds better to our considered moral judgments. © 2014 John Wiley & Sons Ltd.

  20. A Typical Presentation of Orbital Pseudotumor Mimicking Orbital Cellulitis

    J. Ayatollahi

    2013-10-01

    Full Text Available Introduction: Orbital pseudotumor, also known as idiopathic orbital inflammatory syndrome (IOIS, is a benign, non- infective inflammatory condition of the orbit without identifiable local or systemic causes. The disease may mimics a variety of pathologic conditions. We pre-sent a case of pseudotumor observed in a patient admitted under the name of orbital celluli-ties. Case Report: A 26-year-old woman reffered to our hospital with the history of left ocular pain and headache 2 days before her visit.. Ophthalmological examination of the patient was normal except for the redness and lid edema, mild chemosis and conjunctival injection. Gen-eral assessment was normal but a low grade fever was observed. She was hospitalized as an orbital cellulitis patient. She was treated with intravenous antibiotics. On the third day , sud-denly diplopia, proptosis in her left eye and ocular pain in her right side appeared. MRI re-vealed bilateral enlargement of extraocular muscles. Diagnosis of orbital pseudotumor was made and the patient was treated with oral steroid.She responded promptly to the treatment. Antibiotics were discontinued and steroid was tapered in one month period under close fol-low up. Conclusion: The clinical features of orbital pseudotumor vary widely . Orbital pseudotumor and orbital cellulitis can occasionally demonstrate overlapping features.. Despite complete physical examination and appropriate imaging, sometimes correct diagnosis of the disease would be difficult (Sci J Hamadan Univ Med Sci 2013; 20 (3:256-259

  1. Disseminated Cryptococcosis presenting as cellulitis in a renal transplant recipient.

    Chaya, Ramachandraiah; Padmanabhan, Srinivasan; Anandaswamy, Venugopal; Moin, Aumir

    2013-01-15

    Cellulitis is an unusual presentation of cryptococcal infection in renal allograft recipients. In such patients, disseminated cryptococcal infection can result in significant morbidity and mortality. Patients are often treated with antibiotics before a definitive diagnosis is made, delaying appropriate therapy. We describe the case of a 43-year-old post renal transplant recipient presenting with fever and swelling in the right thigh. On physical examination, the patient was found to have features suggestive of cellulitis with minimal slurring of speech. Material obtained from incision and drainage of the wound showed yeast cells resembling Cryptococcus spp. Blood culture and cerebrospinal fluid culture were also found to have growth of Cryptococcus neoformans. He received treatment with amphotericin B 6 mg/kg daily intravenously for two weeks, then continued with fluconazole 400 mg daily for three months. The patient showed a remarkable improvement. There was no recurrence of cryptococcosis after four months of follow-up. The diagnosis of disseminated cryptococcosis should be considered in differential diagnosis of cellulitis among non HIV immunocompromised hosts. A high clinical suspicion and early initiation of therapy is needed to recognize and treat patients effectively.

  2. Mesures experimentales de l'impact des revetements hydrophobeset superhydrophobes sur la trainee et la portance d'un profil aerodynamique propre et glace

    Villeneuve, Eric

    Ce projet, realise a la demande du Laboratoire International des Materiaux Antigivre, a pour but de mesurer et definir experimentalement l'impact de revetements hydrophobes sur les coefficients de trainee et de portance d'un profil NACA 0012. Pour ce faire, la balance aerodynamique du LIMA devait tout d'abord etre amelioree afin d'offrir une sensibilite suffisante pour realiser le projet. Plusieurs ameliorations ont ete faites, comme le changement des cellules de charge, la diminution du nombre de cellules de charge, le changement du cadre de la balance, etc. Une fois ces ameliorations terminees, la reproductibilite, l'exactitude et la sensibilite ont ete valides afin de s'assurer de la fiabilite des resultats offerts par la balance. Pour les angles d'attaque etudies avec les revetements, soient -6° et 0°, la balance a une reproductibilite de +/-2,06% a 360 000 de nombre de Reynolds. Pour valider la sensibilite, des essais a -6° et 0° d'angle d'attaque et des nombres de Reynolds de 360 000 et 500 000 ont ete faits avec des papiers sables. Les resultats de ces essais ont permis de, tracer des courbes de tendances du coefficient de trainee du NACA 0012 en fonction de la rugosite de surface et d'etablir la valeur de la sensibilite de la balance a +/-8 mu m. Cinq revetements populaires ont ete choisis pour l'experimentation, soient le Wearlon, le Staclean, le Hirec, le Phasebreak ainsi que le Nusil. Les revetements sont soumis aux memes conditions experimentales que les papiers sables, et une rugosite equivalente est trouvee par extrapolation des resultats. Cependant, les rugosites equivalentes de surfaces different entre -6° et 0°. Les essais avec le Staclean et le Hirec donnent des coefficients de trainee equivalent a ceux avec l'aluminium, alors que le Wearlon, le Nusil et le Phasebreak donnent une augmentation du coefficient de trainee de 13%, 17% et 25% respectivement par rapport a l'aluminium. Pour les coefficients de portance, la balance ne detecte pas l

  4. Antimicrobial resistance of bacterial strains isolated from avian cellulitis

    MM Santos

    2014-03-01

    Full Text Available Avian cellulitis is an inflammatory process in the subcutaneous tissue, mainly located in the abdomen and thighs. This problem is commonly observed in poultry at slaughter and it is considered one of the major causes of condemnation of carcasses in Brazil. The aim of this study was to perform the microbial isolation of lesions of avian cellulitis from a processing plant located in the State of Goiás in order to analyze antimicrobial resistance by antibiogram test and to detect resistance genes by polymerase chain reaction. A total of 25 samples of avian cellulitis lesions were analyzed, from which 30 bacterial strains were isolated. There were eleven (44% strains of Escherichia coli, nine (36% strains of Staphylococcus epidermidis, seven (28% strains of Proteus mirabilis and three (12% strains of Manheimiahaemolytica. The antibiogram test showed that all strains were resistant to at least one antimicrobial. The gene of antimicrobial resistance tetB was detected in E. coli, S. epidermidis and P. mirabilis strains, and was the most frequently observed gene. The gene of antimicrobial resistance Sul1 was detected in all bacterial species, while tetA was found in E. coli and S. epidermidis strains, SHV in E. coli strains, S. epidermidis and P. mirabilis,and cat1 in one P. mirabilis strain. The results suggest a potential public health hazard due to the ability of these microorganisms to transmit antimicrobial resistancegenes to other microorganisms present in the intestinal tract of humans and animals, which may affect clinical-medical usage of these drugs.

    2014-01-01

    Eosinophilic cellulitis (Wells’ syndrome) is an uncommon condition of unknown etiology. Wells’ syndrome is usually seen in adulthood but very rare in childhood. Although pathogenesis of the disease is not very clear, it is a hypersensitivity reaction developing against a variety of exogenous and endogenous antigenic stimuli. Paraphenylenediamine is a strong allergen frequently used as a temporary henna tattoo, which makes the color darker. Here, a 9-year-old male patient with Wells’ syndrome is presented, which developed following a temporary henna tattoo and shown by the patch test sensitivity to paraphenylenediamine. PMID:25395929

  9. Facial Cellulitis Arising from Dens Evaginatus: A Case Report

    Chun-Ming Chen

    2005-07-01

    Full Text Available Dens evaginatus is a developmental anomaly that produces a tubercle on the occlusal surface of a tooth. It is found most frequently in the mandibular premolars. The occlusal tubercle easily causes occlusal interferences. Attrition or fracture of the tubercle can lead to pulpitis, pulp necrosis, periapical pathosis, and periapical infection. This case report illustrates the treatment of facial cellulitis arising from dens evaginatus with open apex. Calcium hydroxide was used for the apexification procedure. One year after canal obturation, radiography revealed no apical pathosis and the apical seal was evident.

  14. Bacterial Etiology and Risk Factors Associated with Cellulitis and Purulent Skin Abscesses in Military Trainees.

    Ryan C Johnson

    Full Text Available Military trainees are at high risk for skin and soft-tissue infections (SSTIs. Although Staphylococcus aureus is associated with purulent SSTI, it is unclear to what degree this pathogen causes nonpurulent cellulitis. To inform effective prevention strategies and to provide novel insights into SSTI pathogenesis, we aimed to determine the etiology of SSTI in this population. We conducted a prospective observational study in US Army Infantry trainees with SSTI (cutaneous abscesses and cellulitis from July 2012 through December 2014. We used standard microbiology, serology, and high-throughput sequencing to determine the etiology of SSTI. Furthermore, we compared purported risk factors as well as anatomic site colonization for S. aureus. Among 201 SSTI cases evaluated for SSTI risk factors, cellulitis was associated with lower extremity blisters (P = 0.01 and abscess was associated with methicillin-resistant S. aureus (MRSA colonization (P<0.001. Among the 22 tested cellulitis cases that were part of the microbiome analysis, only 1 leading edge aspirate was culturable (Coagulase-negative Staphylococcus. Microbiome evaluation of aspirate specimens demonstrated that Rhodanobacter terrae was the most abundant species (66.8% average abundance, while abscesses were dominated by S. aureus (92.9% average abundance. Although abscesses and cellulitis share the spectrum of clinical SSTI, the bacterial etiologies as determined by current technology appear distinct. Furthermore, the presence of atypical bacteria within cellulitis aspirates may indicate novel mechanisms of cellulitis pathogenesis.NCT01105767.

    2016-06-01

    Lemierre syndrome is characterized by a septic thrombophlebitis of the internal jugular vein (IJV) following an oropharyngeal infection. We report a case of Lemierre syndrome that occurred in a context of angina and necrotizing cellulitis of the neck in a 45-year-old patient. The Doppler ultrasound exam of the neck vessels and a neck CT showed an IJV thrombophlebitis. No germ could be isolated in the samples (blood culture, pus). The treatment associated antibiotics, heparin and surgical debridement of the necrotic tissues with extraction of the thrombus after ligation and section of the IJV. The postoperative course was uneventful. Lemierre syndrome is a rare but serious disease. Its low incidence makes him a forgotten disease. It should be systematically suspected in any oropharyngeal infection with the presence of a large painful swelling of the neck. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    2014-03-01

    Full Text Available Chemical cellulitis is the reaction of the integuments in response to the administration of toxic substances, leading to an acute inflammatory reaction that develops into an abscess or necrosis. This disease is not frequently treated in the Department of Orthopedics and Traumatology of the Joaquin Albarrán Clinical-Surgical Hospital. We present the case of a patient who attended our institution because of increased volume in both upper limbs at the biceps and triceps areas, and marked skin necrosis accompanied by lesions of axillary adenopathy, one as an abscess. Antibiotics were prescribed prior to the completion of cultures, antibiogram and dressing under anesthesia, at present the lesions are in the healing phase.

    Shachor-Meyouhas, Yael; Ravid, Sarit; Suhair, Hanna; Kassis, Imad

    2012-08-01

    Primary cutaneous nocardiosis is an infrequent infection among children, generally affecting immunocompromised hosts. It is caused by Gram positive bacteria, partially alcohol and acid resistant which are saprophytes of the soil, water and organic matter. In most cases the causal agent enters through inhalation, and hematogenous dissemination may occur mainly among the immune compromised patients. Direct cutaneous inoculation is less frequent, especially among children. We report an 8-year old female who lives in an urban house with a small garden, who presented with an ulcer on her right shin accompanied by surrounding cellulitis, pain, swelling and fever. The patient's medical history was unremarkable, with no exposure to animals or travelling, except for rafting on the Jordan River the previous week. Culture from the ulcer grew Nocardia brasiliensis, and she recovered after 8 weeks of therapy with trimethoprim-sulphamethoxazole.

    White, S D; Rosychuk, R A; Stewart, L J; Cape, L; Hughes, B J

    1989-12-01

    The records of 15 dogs diagnosed as having juvenile cellulitis (juvenile pyoderma, puppy strangles) were evaluated for clinical, laboratory, and therapeutic results. Mandibular lymphadenopathy was observed in 14 dogs, and was not associated with skin lesions in 5 dogs. Edema, pustules, papules, or crusts were noticed periorally, periocularly, on the chin or muzzle, or in the ears of those dogs with skin lesions. Eight dogs were lethargic; fever and anorexia were inconsistent findings. Four dogs had signs of pain on manipulation of their joints. Complete blood counts revealed leukocytosis with neutrophilia in 4 dogs, and normocytic, normochromic anemia in 6 dogs. Three dogs had suppurative lymphadenitis with many neutrophils. Cytology of the aspirate of pustules or abscesses in 6 dogs revealed many neutrophils without bacteria. Coagulase-positive Staphylococcus spp were isolated from draining lesions in 2 dogs. Intact abscesses and lymph nodes were negative for bacterial growth in 4 dogs. Three of these dogs were being administered antibiotics at the time of bacterial culturing. Cytology of the aspirates of joints in 3 of the 4 dogs with joint pain revealed suppurative arthritis with no bacteria, and the aspirates were negative for bacterial growth on culturing, although all 3 dogs were being administered antibiotics at the time of culturing. Of 12 dogs initially treated with antibiotics, only 4 (33%) responded favorably; the other 8 dogs were then given antibiotics and corticosteroids. Three dogs were initially given antibiotics and corticosteroids. All dogs treated concurrently with antibiotics and corticosteroids responded favorably. One of these dogs had a relapse after treatment was discontinued. The concurrent arthritis in 4 of the dogs resolved with treatment of the juvenile cellulitis and did not redevelop once the medication was discontinued. Concurrent treatment with antibiotics (cephalosporins) and prednisone (2.2 mg/kg of body weight/day) was the most

    Full Text Available Orbital cellulitis is an infection of soft tissue behind the orbital septum. Common pathogens isolated include Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pneumoniae. It is a straightforward diagnosis and usually responds to empirical treatment without any sequela. We report a case of orbital cellulitis caused by Enterococcus faecalis, which was complicated by myositis of levator palpebrae superioris. To the best of our knowledge, only one case report exists dating way back to 1986.

  10. Fairness and nanotechnology concern.

    McComas, Katherine A; Besley, John C

    2011-11-01

    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. © 2011 Society for Risk Analysis.

    2017-01-01

    This short essay reflects on developments in the law, scholarship, and practice of fair use since the publication in 2004 of an earlier article on patterns in fair use practice and adjudication. It synthesizes many of those developments in the idea of “Madisonian” fair use, borrowing the separation of powers metaphor from James Madison’s work on the US Constitution and applying it, lightly and in a preliminary way, to copyright.

Their work is expanded to show that sellers rely on comparable sales data for estimating FMV. Both results are used to suggest that current practices over-emphasize the discounted cash flow approach to estimating fair market value

    After the demise of the social contract theory, the argument from fair play, which employs the principle of fair play, has been widely acknowledged as one of the most promising ways of justifying political obligation. First, I articulate the most promising version of the principle of fair play. Then, I show that free riders play fair, that is, that their moral fault lies not in unfairness but in the violation of a rule by appealing to the example of three-in-a-boat. Finally, I conclude that e...

    Cervicofacial cellulitises are dominated by dental affections. The aim of this study is to describe etio-epidemiological and therapeutic aspects of cervicofacial cellulitis of dental cause at the CNHU-HKM in Cotonou (Benin). It's a retrospective study from 1998 to 2007 included patients with inflammatory cervicofacial tumefaction of dental cause. A glycaemia, a HIV serology and a blood formula numeration are realized. Some patients practiced standard oral and dental radio. Patients were hospitalized and received mono, bi or triple antibiotic. Lancing with swab of pus for cytobacteriological and antibiogram examination was realized for some of patients. Dental cares were been systematic. 68 cases whose 53 dental cause where been collected 77.94%. Bracket concern patients between 0-20 and 20-40 years old (64.15%). Males were, more concerned. Dental traumatisms find again (18.88%), tooth decay (56.60%) and 24.53% patients practiced dental extraction. Anti inflammatory practiced by 67.92% patients associated to antibiotic in 41.51% cases. The three latest molar were concerned to 26 patients. Among those last 22 had attack of mandibular teeth. Treatment consisted in lancing drainage to 2/3 patients in 83.40% cases associated to tri antibiotic. Evolution has been favourable with recovery to 86.67%; 6 decreases to 13.33% cases. Cervicofacial cellulitises are dangerous, rapidly responsible of deceases by extension. A better oral and dental hygiene would improved prognosis.

  18. Response of hematopoietic stem cells to ionizing radiation; Reponse des cellules souches hematopoitiques aux radiations ionisantes

    Simonnet, A

    2008-12-15

    Hematopoietic stem cells (HSCs) maintain blood and immune system throughout life and restore them after hematological injuries. Exposure of an organism to ionizing radiation (IR) causes rapid and acute myelosuppression and challenges the replenishment capacity of HSCs. Yet, the precise damages that are generated remain largely unexplored. To better understand these effects, phenotypic and functional changes in the stem/progenitor compartments of sublethally irradiated mice were monitored over a ten week period after radiation exposure. We report that shortly after sublethal IR-exposure, HSCs, defined by their repopulating ability, still segregate in the Hoechst dye excluding side population (SP); yet, their Sca-1 (S) and c-Kit (K) expression levels are increased and severely reduced, respectively, with a concurrent increase in the proportion of SP{sup SK} cells positive for established indicators of HSC presence: CD150{sup +} and CD105{sup +}. A great proportion of HSCs quickly but transiently enter the cell cycle to replenish the bone marrow of myelo-ablated mice. Ten weeks after, whereas bone marrow cellularity has recovered and hematopoietic homeostasis is restored, major phenotypic modifications can be observed within the Lin{sup -/low} Sca-1{sup +} c-Kit{sup +} (LSK) stem/progenitor compartment: CD150{sup +}/Flk2{sup -} and CD150{sup -}/Flk2{sup +} LSK cell frequencies are increased and dramatically reduced, respectively. CD150{sup +} LSK cells also show impaired reconstitution capacity, accrued number of {gamma}-H2AX foci and increased tendency to apoptosis. This demonstrates that the LSK compartment is not properly restored 10 weeks after sublethal exposure, and that long-term IR-induced injury to the bone marrow proceeds, at least partially, through direct damage to the stem cell pool. Thrombopoietin (TPO) has been shown to promote the survival of lethally irradiated mice when administrated quickly after exposure. We investigated the mechanisms underlying this effect, and found in a competitive transplant experiment that a single TPO administration rescued the IR-impaired reconstitution capacity of HSCs early after exposure. In addition, the use of marrow cells from transgenic ubiquitous luciferase-expressing donors combined with bioluminescence imaging technology provided a valuable strategy that allowed visualizing HSC homing of TPO-treated compared to untreated irradiated donors, and enabled the identification of a preferential cellular expansion sites which were inaccessible to investigation in most studies. Finally, we observed that TPO injection right after irradiation considerably attenuates IR-induced long-term injury to the stem/progenitor compartment. Altogether, these data provide novel insights in the cellular response of HSC to IR and the beneficial effects of TPO administration to these cells. (author)

  20. Fair Package Assignment

    Lahaie, Sébastien; Parkes, David C.

    We consider the problem of fair allocation in the package assignment model, where a set of indivisible items, held by single seller, must be efficiently allocated to agents with quasi-linear utilities. A fair assignment is one that is efficient and envy-free. We consider a model where bidders have superadditive valuations, meaning that items are pure complements. Our central result is that core outcomes are fair and even coalition-fair over this domain, while fair distributions may not even exist for general valuations. Of relevance to auction design, we also establish that the core is equivalent to the set of anonymous-price competitive equilibria, and that superadditive valuations are a maximal domain that guarantees the existence of anonymous-price competitive equilibrium. Our results are analogs of core equivalence results for linear prices in the standard assignment model, and for nonlinear, non-anonymous prices in the package assignment model with general valuations.

  1. A suspected dental cellulitis leading to diagnosis of both herpes zoster ophthalmicus and HIV

    Grace E. Parkins, BDS, FDS.RCPS (Glas., FWACS, FGCS

    2015-03-01

    Full Text Available Herpes zoster ophthalmicus and HIV are serious health problems. We report a case of a 37-year-old woman who presented to the Korle-Bu Teaching Hospital with dyspnea and facial cellulitis, and a diagnosis 5 days prior of dental cellulitis made at a district hospital. Investigations revealed that the facial cellulitis was secondary to herpes zoster infection involving the ophthalmic division of the left trigeminal nerve. The patient responded well to oral acyclovir but developed postherpetic neuralgia. During the course of treatment, she was also diagnosed to be HIV-1 positive and was referred for further management. This case represents a unique report in which the patient presented to the hospital with symptoms of cellulitis suggestive of underlying dental infection but was later diagnosed with both herpes zoster ophthalmicus and an underlying HIV infection. Atypical presentations of herpes zoster can occur in HIV/AIDS. Signs of herpes zoster infection with cellulitis should alert the clinician that the patient may have a possible underlying immunosuppressive disease. The population must be educated regarding the importance of early presentation and careful compliance with treatment as well as regular follow-ups.

  2. Delayed breast cellulitis: An evolving complication of breast conservation

    Indelicato, Daniel J.; Grobmyer, Stephen R.; Newlin, Heather; Morris, Christopher G.; Haigh, Linda S.; Copeland, Edward M.; Mendenhall, Nancy Price

    2006-01-01

    Purpose: Delayed breast cellulitis (DBC) is characterized by the late onset of breast erythema, edema, tenderness, and warmth. This retrospective study analyzes the risk factors and clinical course of DBC. Methods and Materials: From 1985 through 2004, 580 sequential women with 601 stage T0-2N0-1 breast cancers underwent breast conserving therapy. Cases of DBC were identified according to accepted clinical criteria: diffuse breast erythema, edema, tenderness, and warmth occurring >3 months after definitive surgery and >3 weeks after radiotherapy. Potential risk factors analyzed included patient comorbidity, operative technique, acute complications, and details of adjunctive therapy. Response to treatment and long-term outcome were analyzed to characterize the natural course of this syndrome. Results: Of the 601 cases, 16%, 52%, and 32% were Stage 0, I, and II, respectively. The overall incidence of DBC was 8% (50/601). Obesity, ecchymoses, T stage, the presence and aspiration of a breast hematoma/seroma, removal of >5 axillary lymph nodes, and arm lymphedema were significantly associated with DBC. The median time to onset of DBC from the date of definitive surgery was 226 days. Ninety-two percent of DBC patients were empirically treated with antibiotics. Fourteen percent required more invasive intervention. Twenty-two percent had recurrent episodes of DBC. Ultimately, 2 patients (4%) underwent mastectomy for intractable breast pain related to DBC. Conclusion: Although multifactorial, we believe DBC is primarily related to a bacterial infection in the setting of impaired lymphatic drainage and may appear months after completion of radiotherapy. Invasive testing before a trial of antibiotics is generally not recommended

  6. Empiric outpatient therapy with trimethoprim-sulfamethoxazole, cephalexin, or clindamycin for cellulitis.

    Khawcharoenporn, Thana; Tice, Alan

    2010-10-01

    Limited data exist on optimal empiric oral antibiotic treatment for outpatients with cellulitis in areas with a high prevalence of community-associated methicillin-resistant Staphylococcus aureus (MRSA) infections. We conducted a 3-year retrospective cohort study of outpatients with cellulitis empirically treated at a teaching clinic of a tertiary-care medical center in Hawaii. Patients who received more than 1 oral antibiotic, were hospitalized, or had no follow-up information were excluded. Treatment success rates for empiric therapy were compared among commonly prescribed antibiotics in our clinic: cephalexin, trimethoprim-sulfamethoxazole, and clindamycin. Risk factors for treatment failure were evaluated using multivariate logistic regression analysis. Of 544 patients with cellulitis, 405 met the inclusion criteria. The overall treatment success rate of trimethoprim-sulfamethoxazole was significantly higher than the rate of cephalexin (91% vs 74%; P<.001), whereas clindamycin success rates were higher than those of cephalexin in patients who had subsequently culture-confirmed MRSA infections (P=.01), had moderately severe cellulitis (P=.03), and were obese (P=.04). Methicillin-resistant S. aureus was recovered in 72 of 117 positive culture specimens (62%). Compliance and adverse drug reaction rates were not significantly different among patients who received these 3 antibiotics. Factors associated with treatment failure included therapy with an antibiotic that was not active against community-associated MRSA (adjusted odds ratio 4.22; 95% confidence interval, 2.25-7.92; P<.001) and severity of cellulitis (adjusted odds ratio 3.74; 95% confidence interval, 2.06-6.79; P<.001). Antibiotics with activity against community-associated MRSA, such as trimethoprim-sulfamethoxazole and clindamycin, are preferred empiric therapy for outpatients with cellulitis in the community-associated MRSA-prevalent setting.

  7. Rapid resolution of cellulitis in patients managed with combination antibiotic and anti-inflammatory therapy.

    Dall, Lawrence; Peterson, Sandford; Simmons, Tom; Dall, Amy

    2005-03-01

    There is some evidence to suggest that host inflammatory response has some effect on the clinical manifestations of cellulitis. The objective of this pilot study was to investigate whether the addition of oral nonsteroidal anti-inflammatory (NSAI) therapy to antibiotic treatment hastens resolution of cellulitis-related inflammation. Patients presenting in the emergency department with signs and symptoms of class II cellulitis were assigned to receive treatment with either antibiotic therapy alone (intravenous, supplemented with oral cephalexin or an equivalent) for 10 days (n = 33) or antibiotic therapy for 10 days plus an oral anti-inflammatory (ibuprofen 400 mg every 6 hours) for 5 days (n = 31). Patients were discharged as soon as possible to complete their therapy on an outpatient basis. The addition of an oral anti-inflammatory agent significantly (P < .05) shortened the time to regression of inflammation and complete resolution of cellulitis. Twenty-four of 29 evaluable patients (82.8%) who received supplemental anti-inflammatory treatment showed regression of inflammation within 1 to 2 days compared with only 3 of 33 patients (9.1%) treated without an anti-inflammatory in the same time frame. All patients receiving adjunctive anti-inflammatory treatment experienced complete resolution of cellulitis in 4 to 5 days or less, while 24.2% (8/33) of patients treated with antibiotic alone required 6 to 7 days, and 6.1% (2/33) required 7 days or more (P < .05). This small preliminary study provides some promising data, suggesting that the supplemental use of anti-inflammatory therapy may hasten the time to regression of inflammation and complete resolution of cellulitis.

  8. Computational Fair Division

    Branzei, Simina

    Fair division is a fundamental problem in economic theory and one of the oldest questions faced through the history of human society. The high level scenario is that of several participants having to divide a collection of resources such that everyone is satisfied with their allocation -- e.g. two...... heirs dividing a car, house, and piece of land inherited. The literature on fair division was developed in the 20th century in mathematics and economics, but computational work on fair division is still sparse. This thesis can be seen as an excursion in computational fair division divided in two parts....... The first part tackles the cake cutting problem, where the cake is a metaphor for a heterogeneous divisible resource such as land, time, mineral deposits, and computer memory. We study the equilibria of classical protocols and design an algorithmic framework for reasoning about their game theoretic...

  9. Vehicle underbody fairing

    Ortega, Jason M.; Salari, Kambiz; McCallen, Rose

    2010-11-09

    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.

  10. Customizing Fair Use Transplants

    Peter K. Yu

    2018-02-01

    Full Text Available In the past decade, policymakers and commentators across the world have called for the introduction of copyright reform based on the fair use model in the United States. Thus far, Israel, Liberia, Malaysia, the Philippines, Singapore, South Korea, Sri Lanka and Taiwan have adopted the fair use regime or its close variants. Other jurisdictions such as Australia, Hong Kong and Ireland have also advanced proposals to facilitate such adoption. This article examines the increasing efforts to transplant fair use into the copyright system based on the U.S. model. It begins by briefly recapturing the strengths and weaknesses of legal transplants. The article then scrutinizes the ongoing effort to transplant fair use from the United States. Specifically, it identifies eight modalities of transplantation. This article concludes with five lessons that can be drawn from studying the ongoing transplant efforts.

  11. Is Equality Fair?

    Arthur Tarasov

    2015-11-01

    Full Text Available This paper attempts to answer the question whether people consider decisions that lead to equal outcomes fair. I find that this is not always the case. In an experiment where subjects are given equal opportunities to choose how to divide money between each other in a two-player game, any strategy is perceived to be fair more than half the time, including the profit-maximizing strategy. The equal divisions that lead to equal outcomes are sometimes considered unfair by both players. Moreover, players frequently punished the others, whose decisions led to equal outcomes. I hypothesize that such punishments occur because people have different conceptions of what a fair outcome and fair punishment are

  12. Fair weather atmospheric electricity

    Harrison, R G

    2011-01-01

    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.

  16. The FAIR proton linac

    Kester, O.

    2015-01-01

    FAIR - the Facility for Antiproton and Ion Research in Europe - constructed at GSI in Darmstadt comprises an international centre of heavy ion accelerators that will drive heavy ion and antimatter research. FAIR will provide worldwide unique accelerator and experimental facilities, allowing a large variety of fore-front research in physics and applied science. FAIR will deliver antiproton and ion beams of unprecedented intensities and qualities. The main part of the FAIR facility is a sophisticated accelerator system, which delivers beams to different experiments of the FAIR experimental collaborations - APPA, NuSTAR, CBM and PANDA - in parallel. Modern H-type cavities offer highest shunt impedances of resonant structures of heavy ion linacs at low beam energies < 20 MeV/u and enable the acceleration of intense proton and ion beams. One example is the interdigital H-type structure. The crossed-bar H-cavities extend these properties to high energies even beyond 100 MeV/u. Compared to conventional Alvarez cavities, these crossed-bar (CH) cavities feature much higher shunt impedance at low energies. The design of the proton linac is based on those cavities

  1. Rapid treatment reduces hospitalization for pediatric patients with odontogenic-based cellulitis.

    Thikkurissy, Sarat; Rawlins, Joseph T; Kumar, Ashok; Evans, Erik; Casamassimo, Paul S

    2010-07-01

    The study aimed to assess characteristics of facial cellulitis admissions and their relationship to cost of hospitalization (COH) and length of stay (LOS) in children ages 0 to 20 years at an urban hospital and to compare outcomes of rapid management to published and national statistics for LOS and COH. A retrospective review of 376 charts of facial cellulitis admissions between 2000 and 2006 revealed 63 of confirmed odontogenic cases from which cellulitis characteristics, COH, and LOS were gleaned. Variables were correlated to LOS and COH. Data on LOS and cost of admission were compared to published studies and 506 entries from the 2006 Kids' Inpatient Database (KID). Of 63 charts included, children included were 8.3 years (SD, +/-3.8 years) and equal in sex distribution. Treatment rendered and site of infection had no significant relationship to COH. Overall mean hospital LOS was 2.08 days and significantly less as compared to 3.97 days for published studies and 3.4 days for KID (P KID. In the management of pediatric facial cellulitis of odontogenic origin, rapid treatment had a significant positive impact on length of stay and total cost of treatment compared to published studies and nationally reflective data.

  5. Evaluating the Laboratory Risk Indicator to Differentiate Cellulitis from Necrotizing Fasciitis in the Emergency Department

    Michael M. Neeki

    2017-05-01

    Full Text Available Introduction: Necrotizing fasciitis (NF is an uncommon but rapidly progressive infection that results in gross morbidity and mortality if not treated in its early stages. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC score is used to distinguish NF from other soft tissue infections such as cellulitis or abscess. This study analyzed the ability of the LRINEC score to accurately rule out NF in patients who were confirmed to have cellulitis, as well as the capability to differentiate cellulitis from NF. Methods: This was a 10-year retrospective chart-review study that included emergency department (ED patients ≥18 years old with a diagnosis of cellulitis or NF. We calculated a LRINEC score ranging from 0–13 for each patient with all pertinent laboratory values. Three categories were developed per the original LRINEC score guidelines denoting NF risk stratification: high risk (LRINEC score ≥8, moderate risk (LRINEC score 6–7, and low risk (LRINEC score ≤5. All cases missing laboratory values were due to the absence of a C-reactive protein (CRP value. Since the score for a negative or positive CRP value for the LRINEC score was 0 or 4 respectively, a LRINEC score of 0 or 1 without a CRP value would have placed the patient in the “low risk” group and a LRINEC score of 8 or greater without CRP value would have placed the patient in the “high risk” group. These patients missing CRP values were added to these respective groups. Results: Among the 948 ED patients with cellulitis, more than one-tenth (10.7%, n=102 of 948 were moderate or high risk for NF based on LRINEC score. Of the 135 ED patients with a diagnosis of NF, 22 patients had valid CRP laboratory values and LRINEC scores were calculated. Among the other 113 patients without CRP values, six patients had a LRINEC score ≥ 8, and 19 patients had a LRINEC score ≤ 1. Thus, a total of 47 patients were further classified based on LRINEC score without a CRP value

  6. Developing fair compensation structures

    The issue of finding an effective way to incorporate Aboriginal values into the process of developing fair compensation structures was discussed. This paper discusses pricing intangible values using dollars, but it was emphasized that 'values' are whatever are important to us. Therefore, in order to achieve fair compensation, creative alternatives that are value-focused should be pursued. In addition to the more straight-forward monetary compensation, compensation could also be about avoiding losses, mitigating adverse impacts, achieving better communication, and promoting cultural understanding. 25 refs., 2 tabs

  8. Effets des electrons secondaires sur l'ADN

    Boudaiffa, Badia

    Les interactions des electrons de basse energie (EBE) representent un element important en sciences des radiations, particulierement, les sequences se produisant immediatement apres l'interaction de la radiation ionisante avec le milieu biologique. Il est bien connu que lorsque ces radiations deposent leur energie dans la cellule, elles produisent un grand nombre d'electrons secondaires (4 x 104/MeV), qui sont crees le long de la trace avec des energies cinetiques initiales bien inferieures a 20 eV. Cependant, il n'y a jamais eu de mesures directes demontrant l'interaction de ces electrons de tres basse energie avec l'ADN, du principalement aux difficultes experimentales imposees par la complexite du milieu biologique. Dans notre laboratoire, les dernieres annees ont ete consacrees a l'etude des phenomenes fondamentaux induits par impact des EBE sur differentes molecules simples (e.g., N2, CO, O2, H2O, NO, C2H 4, C6H6, C2H12) et quelques molecules complexes dans leur phase solide. D'autres travaux effectues recemment sur des bases de l'ADN et des oligonucleotides ont montre que les EBE produisent des bris moleculaires sur les biomolecules. Ces travaux nous ont permis d'elaborer des techniques pour mettre en evidence et comprendre les interactions fondamentales des EBE avec des molecules d'interet biologique, afin d'atteindre notre objectif majeur d'etudier l'effet direct de ces particules sur la molecule d'ADN. Les techniques de sciences des surfaces developpees et utilisees dans les etudes precitees peuvent etre etendues et combinees avec des methodes classiques de biologie pour etudier les dommages de l'ADN induits par l'impact des EBE. Nos experiences ont montre l'efficacite des electrons de 3--20 eV a induire des coupures simple et double brins dans l'ADN. Pour des energies inferieures a 15 eV, ces coupures sont induites par la localisation temporaire d'un electron sur une unite moleculaire de l'ADN, ce qui engendre la formation d'un ion negatif transitoire

  15. PROTON MICROSCOPY AT FAIR

    Merrill, F. E.; Mariam, F. G.; Golubev, A. A.; Turtikov, V. I.; Varentsov, D.

    2009-01-01

    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.

    Twenty-seven engineers involved in the FAIR project in Germany recently spent three days at CERN. The purpose of their visit: tour ALICE and meet with CERN engineers. This marks the start of a close cooperation. The FAIR project engineers and their CERN counterparts.If you want to build a new particle accelerator and wish to benefit from existing expertise, who do you go to see? Well… why not go straight to CERN? That’s what this group of 27 engineers did. They are working on a new accelerator project, the Facility for Antiproton and Ion Research (FAIR), to be built at the heavy-ion research centre GSI located near Darmstadt, Germany. Representing a variety of disciplines, from manufacturing to architecture, they will be responsible for making the project a reality. The visit was organised from 14-16 October, making it possible to include a tour of the ALICE experiment prior to the re-start of the LHC. However, the main goal was ...

  17. Fair trade international surrogacy.

    Humbyrd, Casey

    2009-12-01

    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.

  18. Our experience using primary oral antibiotics in the management of orbital cellulitis in a tertiary referral centre.

    Cannon, P S; Mc Keag, D; Radford, R; Ataullah, S; Leatherbarrow, B

    2009-03-01

    Orbital cellulitis is conventionally managed by intravenous (i.v.) antibiotic therapy, followed by oral antibiotics once the infection shows signs of significant improvement. We report 4 years of experience using primary oral ciprofloxacin and clindamycin in cases of orbital cellulitis. Oral ciprofloxacin and clindamycin have a similar bioavailability to the i.v. preparations and provide an appropriate spectrum of antibiotic cover for the pathogens responsible for orbital cellulitis. A retrospective review was performed that identified all patients with orbital cellulitis and treated with primary oral antibiotic therapy admitted to the Manchester Royal Eye Hospital between March 2003 and March 2007. Age, stage of disease, surgical intervention, hospital duration, and complications were obtained. A comparison was made with patients admitted to our unit with orbital cellulitis and treated with primary i.v. antibiotics between March 2000 and March 2003. Nineteen patients were included in the review for the period March 2003 to March 2007, which comprised of 7 children and 12 adults. Five patients required surgical intervention. All patients responded to the oral regimen, 18 patients had no change to their oral antibiotic therapy. Mean hospital stay was 4.4 days. There were no complications. Empirical oral ciprofloxacin and clindamycin combination may be as safe and effective as i.v. therapy in the management of orbital cellulitis. Oral treatment can offer the advantages of rapid delivery of the first antibiotic dose, fewer interruptions in treatment, and simplified delivery of medication particularly in children.

  20. Facing the Danger Zone: The Use of Ultrasound to Distinguish Cellulitis from Abscess in Facial Infections

    Dywanda L. Lewis

    2014-01-01

    Full Text Available Physical exam alone is often insufficient to determine whether or not cellulitis is accompanied by an abscess. Bedside ultrasound can be a valuable tool in ruling out suspected abscess by allowing direct visualization of a fluid collection. The proximity of the infection to adjacent structures can also be determined, thus aiding clinical decision making. Patients with cellulitis near the eye and nose are of particular concern due to the adjacent facial structures and the anatomy of the venous drainage. Accurately determining the presence or absence of an associated abscess in these patients is a crucial step in treatment planning. The purpose of this report is to (1 emphasize the benefits of bedside ultrasound when used in conjunction with the physical exam to rule out abscess; (2 demonstrate the utility of bedside ultrasound in planning a treatment strategy for soft tissue infection; (3 depict an instance where ultrasound detected an abscess when computed tomography (CT scan did not.

  1. A case of cellulitis-like foreign body reaction after hyaluronic acid dermal filler injection

    Yo Sup Shin

    2018-03-01

    Full Text Available A 58-year-old female presented with 3 weeks history of painful skin lesion on the right cheek. Diagnosis was cellulitis based on the clinical manifestation and laboratory test. However, skin lesion did not improve with antibiotics, and as a consequence, biopsy was performed. Based on histopathological findings and additional information of her previous history of intradermal filler injection, the lesion was diagnosed to be foreign body reaction. Previous reported cases of foreign body reaction induced by hyaluronic acid dermal filler typically manifested as nodular lesions, but cellulitis-like cutaneous manifestation has not been reported. Therefore, we report this interesting case of foreign body reaction after hyaluronic acid dermal filler injection.

  2. Mycobacterium avium-intracellulare cellulitis occurring with septic arthritis after joint injection: a case report

    Murdoch David M

    2007-02-01

    Full Text Available Abstract Background Cellulitis caused by Mycobacterium avium-intracellulare has rarely been described. Mycobacterium avium-intracellulare is a rare cause of septic arthritis after intra-articular injection, though the causative role of injection is difficult to ascertain in such cases. Case presentation A 57-year-old with rheumatoid arthritis treated with prednisone and azathioprine developed bilateral painful degenerative shoulder arthritis. After corticosteroid injections into both acromioclavicular joints, he developed bilateral cellulitis centered over the injection sites. Skin biopsy showed non-caseating granulomas, and culture grew Mycobacterium avium-intracellulare. Joint aspiration also revealed Mycobacterium avium-intracellulare infection. Conclusion Although rare, skin and joint infections caused by Mycobacterium avium-intracellulare should be considered in any immunocompromised host, particularly after intra-articular injection. Stains for acid-fast bacilli may be negative in pathologic samples even in the presence of infection; cultures of tissue specimens should always be obtained.

  3. The air forces on a systematic series of biplane and triplane cellule models

    Munk, Max M

    1927-01-01

    The air forces on a systematic series of biplane and triplane cellule models are the subject of this report. The test consist in the determination of the lift, drag, and moment of each individual airfoil in each cellule, mostly with the same wing section. The magnitude of the gap and of the stagger is systematically varied; not, however, the decalage, which is zero throughout the tests. Certain check tests with a second wing section make the tests more complete and conclusions more convincing. The results give evidence that the present army and navy specifications for the relative lifts of biplanes are good. They furnish material for improving such specifications for the relative lifts of triplanes. A larger number of factors can now be prescribed to take care of different cases.

  4. [Orbital cellulitis complicated by subperiosteal abscess due to Streptococcus pyogenes infection].

    Ruíz Carrillo, José Daniel; Vázquez Guerrero, Edwin; Mercado Uribe, Mónica Cecilia

    Orbital cellulitis is an infectious disease that is very common in pediatric patients, in which severe complications may develop. Etiological agents related to this disease are Haemophilus influenzae B, Staphylococcus aureus, Streptococcus pneumoniae and Moraxella catarrhalis, which correspond to 95% of cases. Moreover, Streptococcus beta hemolytic and anaerobic microorganisms may also be present corresponding to < 5% of the cases. We present an uncommon case of cellulitis complicated by sub-periosteal abscess caused by Streptococcus pyogenes (Group A beta hemolytic streptococcus). A 9-year-old male patient with a history of deficit disorder and hyperactivity since 5 years of age. His current condition started with erythema in the external edge of the right eye, increase in peri-orbicular volume with limitation of eyelid opening, progression to proptosis, pain with eye movements and conjunctival purulent discharge. Image studies reported subperiosteal abscess and preseptal right with extraocular cellulitis. The patient started with empirical antibiotic treatment, surgical drainage and culture of purulent material from which Streptococcus pyogenes was isolated. Due to the implementation of vaccination schemes against H. influenza and S. pneumoniae since the 90s, the cases by these pathogens have decreased, causing new bacteria to take place as the cause of the infection. The importance of considering S. pyogenes as an etiology of orbital cellulitis is the rapid progression to abscess formation, and the few cases described in the literature.

    Necrotizing cellulitis of dental origin is a serious disease and requires prompt and effective management to avoid adverse outcomes. The purpose of this work is to describe the diagnostic and therapeutic difficulties encountered in this condition. This was a prospective study in the thoracic surgery department of Mali Hospital from January 2011 to February 2015. We collected consecutively 19 cases of complicating cervico-facial cellulitis of dental origin. The anatomical and clinical aspects, therapeutic modalities and difficulties are described. Dental pain and fever were the predominant symptoms followed by cervical edema. Chest CT-scan was the basis for the diagnosis in all cases. Cervicotomy with debridement was the most performed surgical procedure. Pleural drainage was performed in 6 cases. Three patients (15.8%) died. Necrotizing cellulitis of dental origin is a serious disease with high morbidity and mortality. The key radiological examination is the thoracic CT-scan. Early medico-surgical management by emergency care, tailored antibiotic therapy, removal of necrotizing tissues and drainage of collections are required to deliver a good outcome.

  7. European ST80 community-associated methicillin-resistant Staphylococcus aureus orbital cellulitis in a neonate

    Tsironi Evangelia E

    2012-05-01

    Full Text Available Abstract Background Methicillin-resistant Staphylococcus aureus is a serious cause of morbidity and mortality in hospital environment, but also, lately, in the community. This case report is, to our knowledge, the first detailed description of a community-associated methicillin-resistant S. aureus ST80 orbital cellulitis in a previously healthy neonate. Possible predisposing factors of microbial acquisition and treatment selection are also discussed. Case presentation A 28-day-old Caucasian boy was referred to our hospital with the diagnosis of right orbital cellulitis. His symptoms included right eye proptosis, periocular edema and redness. Empirical therapy of intravenous daptomycin, rifampin and ceftriaxone was initiated. The culture of pus yielded a methicillin-resistant S. aureus isolate and the molecular analysis revealed that it was a Panton-Valentine leukocidine-positive ST80 strain. The combination antimicrobial therapy was continued for 42days and the infection was successfully controlled. Conclusions Clinicians should be aware that young infants, even without any predisposing condition, are susceptible to orbital cellulitis caused by community-associated methicillin-resistant S. aureus. Prompt initiation of the appropriate empirical therapy, according to the local epidemiology, should successfully address the infection, preventing ocular and systemic complications.

  8. Successful endoscopic management with Mitomycin C application for sinusitis with orbital cellulitis

    Anil S Harugop

    2013-01-01

    Full Text Available Background: Sinusitis with orbital complication is a potentially fatal disease that has been known since the days of Hippocrates. Primary sinus infection is the most common cause of orbital cellulitis. It is an emergency that threatens not only vision but also life from complications such as meningitis, cavernous sinus thrombosis, and brain abscess. Surgical intervention is mandatory whenever antibiotic treatment fails. There are two surgical options for the drainage, an external approach via a Lynch incision and an intranasal endoscopic procedure. Materials and Methods: Five patients with orbital cellulitis secondary to acute on chronic rhinosinusitis were included in the study from the period of 2010 - 2011. All five patients did not respond to medical management and hence underwent endoscopic sinus surgery with treatment of orbital pathology. At the end of the surgical procedure Mitomycin C in a concentration of 0.4mg/ml was applied with a cottonoid for a period of 4 minutes to prevent chance of adhesion formation. Results: In this series 3 females and 2 male patient with orbital cellulitis secondary to acute on chronic rhinosinusitis underwent endoscopic sinus surgery with treatment of orbital pathology. All 5 patients showed subjective and objective improvement within one week of endoscopic management. Conclusion: Though antibiotics have altered the course of sinusitis, its grave complications still persist in our environment. The excellent results and the absence of any major complications of endoscopic sinus surgery and drainage of abscess with application of Mitomycin C can be recommended as the preferred surgical technique.

  9. Cellulitis Secondary to Liquid Nitrogen Cryotherapy: Case Report and Literature Review.

    Huang, Christina M; Lu, Emily Y; Kirchhof, Mark G

    Liquid nitrogen cryotherapy is a commonly used technique to treat a wide variety of dermatologic conditions including actinic keratoses, non-melanoma skin cancers, verrucae, and seborrheic keratoses. The risks associated with liquid nitrogen cryotherapy are important to know and discuss with patients prior to treatment. We report a case of cellulitis secondary to liquid nitrogen cryotherapy for actinic keratosis. We sought to review the literature for an estimate of secondary infection rates following cryotherapy treatment. We searched Pubmed using the terms cryotherapy and infection or cellulitis. We then looked at articles classified as clinical trials where cryotherapy was used to treat skin conditions. We then selected clinical trials that listed cellulitis or infection as an adverse event. There were no case reports, case series, or review articles detailing the risk of infection from liquid nitrogen cryotherapy. We found 8 articles classified as clinical trials on Pubmed that did list infection as an adverse event. The risk of infection from these studies varied from approximately 2% to 30%. There was a great degree of heterogeneity in treatment sites, length of treatment, and treatment targets. While it is difficult to determine the true incidence of infection from liquid nitrogen cryotherapy, clinicians should endeavor to inform patients of this potential risk.

    2014-01-01

    Axiomatic models of decision under ambiguity with a non-unique prior allow for the existence of Crisp Fair Gambles: acts whose expected utility is nul whichever of the priors is used. But, in these models, the DM has to be indifferent to the addition of such acts. Their existence is then at odds with a preference taking into account the variance of the prospects. In this paper we study some geometrical and topological properties of the set of priors that would rule out the existence of Crisp ...

    1975-04-12

    This research thesis reports a radiobiological study of Dianthus periclinal chimeras performed by submitting plants and plant cuttings at different physiological stages to cobalt-60 gamma irradiation under different dose conditions and rates. The effects of these treatments are studied while growing the so-processed plants and by microscopic examination of sections of irradiated meristems [French] Une etude radiobiologique de chimeres periclinales d'oeillet est effectuee en soumettant au rayonnement gamma du cobalt 60, sous differentes conditions de doses et debits de dose, des plantes entieres et des boutures a des stades physiologiques differents. Les effets des traitements sont observes au cours de la culture des plantes traitees et par l'examen microscopique de coupes des meristemes irradies. La destruction de cellules meristematiques, dans des proportions variables avec les modalites d'irradiation, provoque des modifications de structure des chimeres dont les plus frequentes sont la formation de tiges genetiquement homogenes a partir des differents genotypes existants dans la plante irradiee. Le traitement aux radiations ionisantes constitue donc une methode pratique de detection des chimeres periclinales qui, a l'image de ce qui se passe pour l'oeillet, sont tres repandues chez les plantes cultivees a propagation vegetative. Mais, comme il existe generalement plus de deux ensembles cellulaires meristematiques independants, cette methode ne permet pas, a elle seule, de definir la repartition des differents genotypes dans ces ensembles; elle doit alors etre completee par des etudes genetiques ou des marquages cellulaires tels que des mutations chlorophylliennes ou de genomes. Ainsi la structure de deux varietes d'oeillet a fleurs oranges, qui produisent, apres irradiation, des fleurs rouges et des fleurs jaunes, a ete determinee grace a l'obtention, par traitement a la colchicine, de cytochimeres 4 - 2 - 2 et 2 - 4 - 4.

  14. Judging Fairness in Class Action Settlements

    Catherine Piché

    2010-02-01

    Full Text Available In this paper, I describe the face of modern civil justice and discuss four paradoxes which justify re-evaluating the role of the judge responsible for reviewing class action settlements, in light of modern judicial culture. I also critically evaluate the existing procedures applicable to the fairness review as well as the judicial role described in the caselaw and doctrine, before suggesting a revised, three-parted role for the reviewing judge in the class action settlement context. Ultimately, I suggest that to reach fairness of process and outcome in class action settlements, judges should remain active and creative in their inquisitorial assessment of proposed class action settlements. They should also remain conciliatory, participating in the search for solutions regarding the proposed settlement, always seeking to find the truth (and what is “just” about the proposed settlement, in the utmost respect for the rights of absent class members, the respect of their interests, and the additional consideration of the interests of the defendants and of the public. Dans cet article, je présente l’état de la face de la justice civile moderne et je discute quatre paradoxes qui justifient une réévaluation du rôle du juge responsable de la révision et de l’approbation d’un règlement de recours collectif, à la lumière de la culture juridique moderne. Je propose aussi une évaluation critique des procédures en place s’appliquant à l’évaluation du caracters équitable de la transaction, de même que le rôle du juge décrit dans la jurisprudence et la doctrine, avant de suggérer un rôle révisé. Ce rôle modifié se décline en trois parties. Finalement, je suggère que pour atteindre l’équité de procédure et de résultat dans le cas de règlements en recours collectif, les juges devraient demeurer actifs et créatifs en enquêtant pour évaluer des règlements proposés dans les cas de recours collectifs.

  18. Features and treatment of gas-forming synergistic necrotizing cellulitis: a nine-year retrospective study.

    Ling, Xiangwei; Ye, Yuanyuan; Guo, Hailei; Liu, Zhengjun; Xia, Weidong; Lin, Cai

    2018-03-01

    As many doctors know little about gas-forming synergistic necrotizing cellulitis, we retrospectively explored it in our study. Totally, 30 patients diagnosed with gas-forming synergistic necrotizing cellulitis between November 2006 and September 2015 were included. They were divided into two groups: open drainage group (19 patients) and aggressive debridement group (11 patients). Retrospectively analyzed data comprised demographic characteristics, APACHE II scores, pathogen culture results, bleeding amount during the operation, white blood cell count, length of hospital stay and recovery. The mortality rate was 26% in the open drainage group and 73% in the aggressive debridement group (p=0.023). There was no statistical difference in the APACHE II score before treatment between the open drainageand aggressive debridement groups (16.6±4.5 vs 18.1±7.5, p=0.511). The APACHE II score was significantly higher after treatment in the aggressive debridement group (14.2±5.8 score vs 20.1±9.1, p=0.038). There were no statistical differences in the white blood count cell before and after treatment (13.49 × 109±5.05×109 cells/L vs 17.46×109±6.94×109 cells/L, p=0.082; 10.37×109±3.54×109 cells/L vs 15.47×109 ±7.51×109 cells/L, p=0.055; respectively). The bleeding amount during the operation was significantly more in the aggressive debridement group (315±112 ml vs 105±45 ml, pgas-forming synergistic necrotizing cellulitis, performing open drainage as early as possible isthe most important procedure after admission.

  19. Comparing short to standard duration of antibiotic therapy for patients hospitalized with cellulitis (DANCE): study protocol for a randomized controlled trial

    2014-01-01

    Recommended therapy duration for patients hospitalized with cellulitis is 10-14 days. Unnecessary use of antibiotics is one of the key factors driving resistance. Recent studies have shown that antibiotic therapy for cellulitis in outpatients can safely be shortened, despite residual inflammation.

  20. Etudes physiques des mélanges eau-cryoprotecteurs

    Vassoille, R.; Perez, J.

    The aim of the following review is to present the most important studies concerning the physical properties of water-solutes mixtures used in cryobiology. Cryobiology is a branch of biology which deals with the very low temperature behaviour of cells. This technique is developed today in several directions. The creation of banks of cells and perhaps in a short time of small organs, is the purpose of much research in this domain. Before freezing, living cells are generally put in a solution containing one or more solutes. The role of these solutes is to protect the cells against damage due to crystallization of water (cryoprotectors). The mechanisms of cryoprotection are not well known ; nevertheless the vitreous state formation during cooling is often invoked. So, it is possible to avoid crystallization damage such as mechanical strain (due to an increase of volume of about 10 %) and salt effects (due to osmotic pressure). The conditions in which the vitreous state is obtained, maintained during cooling, storage at low temperature and rewarming can be defined by physical studies presented in the following review. Le présent travail est essentiellement une revue bibliographique des principales études physiques qui ont été réalisées avec des solutions de composés habituellement employés en cryobiologie. La cryobiologie est une branche de la biologie qui s'intéresse au comportement des cellules à basse température. Cette discipline est actuellement en plein développement dans des domaines très divers. Son principal but est la création de banques de cellules de plus en plus complexes avec comme perspective la conservation des organes. Les cellules vivantes sont généralement placées avant congélation dans une solution contenant divers composés dont le rôle est de protéger les cellules contre les effets de la cristallisation de l'eau. L'action protectrice de ces cryoprotecteurs est encore mal connue; cependant, la formation d'un état vitreux lors du

    2004-05-01

    A four-year-old, entire male toy poodle was presented with a two-and-a-half-week history of ocular discharge progressing to periorbital alopecia, depigmentation, alopecia and ulceration around the muzzle. There was also a haemorrhagic discharge from the ears, pyrexia, lethargy and generalised lymphadenopathy. The clinical, cytological, bacteriological and histopathological findings were consistent with a diagnosis of dermatitis resembling juvenile cellulitis in an adult dog. Glucocorticoid therapy led to rapid resolution of the clinical signs and the dog has remained in remission for two years after cessation of treatment.

  2. Serratia marcescens Bullous Cellulitis in a Splenectomized Patient: A Case Report and Review of the Literature.

    Fournier, John B; Dabiri, Ganary; Thomas, Vinod; Skowron, Gail; Carson, Polly; Falanga, Vincent

    2016-06-01

    Serratia marcescens is a Gram-negative bacillus belonging to the Enterobacteriaceae family. Cutaneous infection with Serratia is rare, and usually occurs in immunocompromised individuals. Primary cutaneous infections are uncommon, but they are typically severe and are associated with significant morbidity and mortality. The pathogenetic factors leading to S. marcescens infection are not fully understood, but contributing virulence factors include proteases, secreted exotoxins, and the formation of biofilm. We report a case of cellulitis occurring in a splenectomized patient, which led to multiple wound debridements and a transmetatarsal amputation. This dramatic case led us to review the published literature on soft tissue infections caused by S. marcescens. © The Author(s) 2016.

  3. Clinical implications of microbial biofilms in chronic rhinosinusitis and orbital cellulitis.

    Nayak, Niranjan; Satpathy, Gita; Prasad, Sujata; Thakar, Alok; Chandra, Mahesh; Nag, T C

    Discovery of sessile mode of microbial existence (Biofilm state) focussed much interest, during the recent years, on the study of biofilms in many recurring and chronic infections. However, the exact role of microbial biofilms in chronic rhinosinusitis and orbital cellulitis were not elucidated earlier. The purpose of the present study was to look for the adherent property and biofilm producing ability of the clinical isolates in chronic rhinosinusitis and orbital cellulitis, and to look for the effects of antimicrobial agents on these biofilms by colorimetric assay and ultrastructural analysis. Organisms were isolated and identified from various clinical samples in patients with chronic sinusitis and orbital cellulitis. Antimicrobial sensitivity testing was carried out by the standard protocol. Biofilms were developed; quantified and antimicrobial drug perfusion through the biofilm model was evaluated by the earlier devised procedure. Electronmicroscopic study of the biofilm was performed by the recommended technique. Of the total of 70 clinical samples processed, 48 i.e. 68.5 % grew bacteria and 13 i.e.(18.6 %) fungi. Staphylococcus aureus (20), S epidermidis (16) and Pseudomonas aeruginosa (6) accounted for the majority of the bacterial isolates. Aspergillus flavus (8), however was the commonest amongst the fungi. A total of 40 bacteria and 8 fungi could be tested for biofilm production. Eighteen (45 %) of the 40 bacterial isolates and 4(50 %) out of the 8 A flavus isolates were found to be biofilm producers. In vitro adherence testing revealed that majority i.e. 16 (88.8 %) of the 18 biofilm positive bacteria were adherent to artificial surfaces. Antimicrobial drug perfusion through the biofilm model was poor. Antimicrobial treatment was totally ineffective against strong biofilm producers, whose electron microscopic picture was quite similar to that observed for biofilm producers without any antimicrobial pre-treatment. Filamentous fungi, like bacteria

  4. Does market competition explain fairness?

    Descioli, Peter

    2013-02-01

    The target article by Baumard et al. uses their previous model of bargaining with outside options to explain fairness and other features of human sociality. This theory implies that fairness judgments are determined by supply and demand but humans often perceive prices (divisions of surplus) in competitive markets to be unfair.

Another coordinated taxation is part of contemporary consumerist polticilor new tax, taxing certain income, especially income individuals is marked by the overall objective of capitalist society, that consumption growth. Fiscal policies are policies the new contemporary consumerism. And this phenomenon influences the distribution of the tax burden among taxpayers, more or less fair. What is tax fairness and how we can quantify? Here's a question that I try to raspunt from equality before the law tax payers. Equality before the tax law is not a primary goal of modern tax policy, it losing ground to tax efficiency goals and its economic and social components. On the other hand though fiscal phenomenon can help to ensure social peace through taxation to keep Sean absolute size of the tax burden and the fact that all are equal before the law, tax law and within given social policies in broadly, social security or insurance in respect restrains can be promoted by themselves and less by fiscal policy.

    This research thesis reports the study of possibility of treatments (or restoration) of a mouse which has been submitted to a lethal dose of X rays. More particularly, the author compared the restoring efficiency of bone marrow and fetal liver injected in a mouse which had been lethally irradiated by a total exposure to X rays. He also studied the functional status of the hemopoietic graft, and the emergence of the secondary disease in mice which had been as well lethally irradiated and then restored by injection of bone marrow and fetal liver. The author then addressed the influence of the induction of immune tolerance of the host with respect to the donor on the survival of a mouse lethally irradiated and restored by homologue bone marrow [French] Des resultats des recherches que nous avons conduites permettent, dans les limites de nos conditions experimentales, d'eclaircir certains aspects du probleme de la restauration des animaux irradies par la greffe de cellules hemopoietiques. On peut admettre que la moelle osseuse de 30 jours est 2 fois plus efficace que le foie foetal de 16 jours, pour ce qui concerne la survie 30 jours; ceci aussi bien en cas de restauration isologue que homologue. En outre, le foie foetal de 16 jours permet une survie d'environ 50 pc plus elevee que les foies foetaux de 13 ou 19 jours; ceci en cas de restauration isologue. On a aussi montre que les degres de capacite restauratrice des differents tissus hemopoietiques dependent du nombre de cellules souches, progenitrices des granulocytes polynucleaires.

    Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis. PMID:28194321

  11. Sinonasal Melioidosis in a Returned Traveller Presenting with Nasal Cellulitis and Sinusitis

    2013-01-01

    Full Text Available We illustrate a case involving a 51-year-old man who presented to a tertiary hospital with sepsis secondary to an abscess of the nasal vestibule and pustular eruptions of the nasal mucosa. Associated cellulitis extended across the face to the eye, and mucosal thickening of the sinuses was seen on computed tomography. The patient underwent incision and drainage and endoscopic sinus surgery. Blood cultures and swabs were positive for a gram-negative bacillus, Burkholderia pseudomallei. He had multiple risk factors including travel to an endemic area. The patient received extended antibiotic therapy in keeping with published national guidelines. Melioidosis is caused by Burkholderia pseudomallei, found in the soil in Northern Australia and Asia. It is transmitted via cutaneous or inhaled routes, leading to pneumonia, skin or soft tissue abscesses, and genitourinary infections. Risk factors include diabetes, chronic lung disease, and alcohol abuse. It can exist as a latent, active, or reactivated infection. A high mortality rate has been identified in patients with sepsis. Melioidosis is endemic in tropical Northern Australia and northeastern Thailand where it is the most common cause of severe community-acquired sepsis. There is one other report of melioidosis in the literature involving orbital cellulitis and sinusitis.

  12. A pilot cross-sectional study of patients presenting with cellulitis to emergency departments.

    Quirke, M

    2014-11-01

    To characterise the Emergency Department (ED) prevalence of cellulitis, factors predicting oral antibiotic therapy and the utility of the Clinical Resource Efficiency Support Team (CREST) guideline in predicting patient management in the ED setting, a prospective, cross-sectional study of consecutive adult patients presenting to 3 Irish EDs was performed. The overall prevalence of cellulitis was 12 per 1,000 ED visits. Of 59 patients enrolled, 45.8% were discharged. Predictors of treatment with oral antibiotics were: CREST, Class 1 allocation (odds ratio (OR) 6.81, 95% Cl =1.5-30.1, p=0.012), patient self-referral (OR= 6.2, 95% Cl 1.9- 20.0, p=0.03) and symptom duration longer than 48 hours (OR 1.2, 95% Cl = 1.0-1.5,p=0.049). In conflict with guideline recommendation, 43% of patients in CREST Class 1 received IV therapy. Treatment with oral antibiotics was predicted by CREST Class 1 allocation, self-referral, symptom duration of more than 48 hours and absence of pre-EO antibiotic therapy.

  13. Stenotrophomonas maltophila cellulitis in an immunocompromised patient presenting with purpura, diagnosed on skin biopsy.

    2016-11-01

    Stenotrophomas maltophilia is an opportunistic Gram-negative bacillus and an important cause of nosocomial infections, particularly in immunosuppressed individuals. Although infections with this organism are most often in the form of pneumonia, bacteremia and endocarditis, awareness of the impact of S. maltophilia skin infections has been increasing. Here we describe a case of S. maltophilia cellulitis in a 65-year-old man with severe neutropenia and purpuric skin lesions to highlight the critical histopathological findings and correlate them with the clinical manifestations of the skin infection with this organism. Because identification of S. maltophilia can be challenging and infections are difficult to manage, this case illustrates essential considerations regarding the multifaceted histopathological, dermatological, clinical and microbiological aspects of the diagnosis and treatment of S. maltophilia cellulitis in a severely immunocompromised patient. Cognizance of the increasing incidence of nosocomial infections with uncommon microorganisms such as S. maltophilia is necessary when presented with atypical cutaneous manifestations, particularly in immunocompromised patients. © 2016 John Wiley & Sons A/S.

    2017-01-01

    Skin and soft tissue infections (SSTI) affect millions of people globally, which represents a significant burden on ambulatory care and hospital settings. The role of sulfamethoxazole-trimethoprim (SXT) in SSTI treatment, particularly when group A Streptococcus (GAS) is involved, is controversial. We conducted a systematic review of clinical trials and observational studies that address the utility of SXT for SSTI treatment, caused by either GAS or Staphylococcus aureus , including methicillin-resistant (MRSA). We identified 196 studies, and 15 underwent full text review by 2 reviewers. Observational studies, which mainly focused on SSTI due to S aureus , supported the use of SXT when compared with clindamycin or β-lactams. Of 10 randomized controlled trials, 8 demonstrated the efficacy of SXT for SSTI treatment including conditions involving GAS. These findings support SXT use for treatment of impetigo and purulent cellulitis (without an additional β-lactam agent) and abscess and wound infection. For nonpurulent cellulitis, β-lactams remain the treatment of choice.

Statistical population were the personnel of education and training administrations regions, which 309 persons from them selected with using simple random sampling. Research instruments were overall fairness with 3 items, cultural values (in two fields including materialism and power distance with 8 items, distributive, procedural and interactional justice with 3,3,3 items respectively, job satisfaction with 3 items and turnover with 3 items. Data were analyzed with using Pearson’s correlation coefficient, structural equation modeling, moderated hierarchical regression and mediating regression analysis. Results showed that there are significant relations between overall fairness with distributive, procedural, interactional justice and turnover, job satisfaction and materialism (P0.05. The results of structural equation modeling and mediating regression analysis showed that overall fairness relatively mediate the relations between procedural justices with turnover. But there was not mediated role for overall fairness in relations between distributive and interactional fairness with turnover and job satisfaction. Moderated regression analysis showed that power distance likely have moderated role in relations between overall fairness with turnover likely.

  1. Fair Value or Market Value?

    Bogdan Cosmin Gomoi

    2014-12-01

    Full Text Available When taking into consideration the issue of defining the “fair value” concept, those less experimented in the area often fall in the “price trap”, which is considered as an equivalent of the fair value of financial structures. This valuation basis appears as a consequence of the trial to provide an “accurate image” by the financial statements and, also, as an opportunity for the premises offered by the activity continuing principle. The specialized literature generates ample controversies regarding the “fair value” concept and the “market value” concept. The paper aims to debate this issue, taking into account various opinions.

    1995-10-01

    Granular cell tumours of neurohypophysis are rare. These tumours are more often encountered as incidental autopsy findings seen in up to 17 % of unselected adult autopsy cases. There are few reports of para-sellar granular cell tumours large enough to cause symptoms. We present three cases of neurohypophysis granular cell tumour and a review of the literature. In one patient, the asymptomatic granular cell tumour was incidentally discovered at surgical removal of a corticotrophic micro-adenoma. The remaining 2 patients had a symptomatic tumour which caused neurological symptoms such as visual disturbance and headaches and endocrine disorders such as hypopituitarism or hyper-prolactinaemia. In these 2 cases, computerized tomography showed a well-circumscribed, contrast-enhanced, intra-sellar and supra-sellar mass. Magnetic resonance imaging demonstrated an isointense gadolinium-enhanced mass in T1-weighted-images. Trans-sphenoidal partial resection was performed and histology was interpreted as a granular cell tumour. The immunohistochemical study was positive for glial fibrillary acidic protein (GEAP) and neuron specific enolase (NSE) in 1 of the 2 tumours and positive for S100 protein and vimentin in both tumours but negative for CD68. The histogenesis of neurohypophysis granular cell tumours is still controversial but ultrastructural and immunohistochemical studies support the theory that may arise from pituicytes, the glial cells of neurohypophysis. Management of these benign, slow growing, tumours is based mainly on neurosurgical resection. Data from the literature do not support a beneficial effect of post operative radiation therapy on postoperative recurrences. (authors). 23 refs., 4 figs., 1 tab.

  11. Dermatitis and cellulitis in leopard geckos (Eublepharis macularius) caused by the Chrysosporium anamorph of Nannizziopsis vriesii.

    Toplon, D E; Terrell, S P; Sigler, L; Jacobson, E R

    2013-07-01

    An epizootic of ulcerative to nodular ventral dermatitis was observed in a large breeding colony of 8-month to 5-year-old leopard geckos (Eublepharis macularius) of both sexes. Two representative mature male geckos were euthanized for diagnostic necropsy. The Chrysosporium anamorph of Nannizziopsis vriesii (CANV) was isolated from the skin lesions, and identification was confirmed by sequencing of the internal transcribed spacer region of the rRNA gene. Histopathology revealed multifocal to coalescing dermal and subcutaneous heterophilic granulomas that contained septate fungal hyphae. There was also multifocal epidermal hyperplasia with hyperkeratosis, and similar hyphae were present within the stratum corneum, occasionally with terminal chains of arthroconidia consistent with the CANV. In one case, there was focal extension of granulomatous inflammation into the underlying masseter muscle. This is the first report of dermatitis and cellulitis due to the CANV in leopard geckos.

  12. The acute orbit: Differentiation of orbital cellulitis from subperiosteal abscess by computerized tomography

    Handler, L.C.; Davey, I.C.; Hill, J.C.; Lauryssen, C.

    1991-01-01

    A series of 65 patients suffering from acute inflammatory disease of the orbit was studied by CT. Ethmoiditis was the cause in the vast majority; trauma and dental extraction played a lesser role in causation. Orbital cellulitis was diagnosed in 17 and subperiosteal abscess in the remaining 48. It was not possible to differentiate 33 pus-containing abscesses from the six with inflammatory masses (phlegmons). The satisfactory response to aggressive medical treatment in those patients with inflammatory masses that were not drained justifies a more conservative approach; surgical drainage being reserved for those with a deterioration in proptosis, ocular movements or vision. Six abscesses arose de novo, of which some were in the orbital fat rather than the subperiosteal space. (orig.)

    2014-07-01

    Review of a case of paraosseous extramedullary hematopoiesis (EMH) affecting the maxillary sinuses and retro-orbital spaces imitating bilateral orbital cellulitis. Maxillofacial EMH causes diagnostic/therapeutic challenges. This case report describes a 4-year-old African American male with sickle cell disease (HbSS) who presented with bilateral orbitofacial swelling. Diagnosis was made with imaging and confirmed with tissue sampling. Partial exchange transfusion was utilized to stop the progression of maxillofacial EMH and to treat the patient's chronic anemia. Follow-up MRI showed regression of orbital and retro-orbital involvement. Early treatment with conservative modalities and close observation may prevent need for more invasive treatments.

  14. Cemento-ossifying Fibroma Of Paranasal Sinus Presenting Acutely As Orbital Cellulitis.

    Khanna, Maneesh; Buddhavarapu, Shanker Rao; Hussain, Sheik Akbar; Amir, Emran

    2009-01-01

    Fibro-osseous lesions of the face and paranasal sinuses are relatively uncommon. These lesions have overlapping clinical, radiologic and pathologic features causing difficulty in diagnosis. Neoplastic fibro-osseous paranasal sinus lesions can be benign or malignant. The benign fibro-osseous lesions described are: ossifying fibroma (and its histologic variants) and fibrous dysplasia. The variants of ossifying fibroma differ in the nature of calcified material (i.e. cementum versus bone), in the location of the lesion (oral versus paranasal sinus or orbital), other morphologic variations (presence of psammomatoid concretions) and biologic behavior (aggressive versus stable). Presence of cementum or bone classifies the lesion as cementifying fibroma or ossifying fibroma respectively while lesions with mixture of both cementum and bone are called cemento-ossifying fibroma. We describe a case of a young adult male with cemento-ossifying fibroma of paranasal sinus presenting acutely as left orbital cellulitis with proptosis.

    Full Text Available Technologies and devices for cosmetic procedures are developing with each passing day. However, increased and unauthorized use of such emerging technologies may also lead to increases in unexpected results and complications as well. Here, we report a case of facial cellulitis after a “beauty parlor” session of skin cleaning with jet stream peeling device in 19-year old female patient for the first time. Complications due to improper and unauthorized use of jet stream peeling devices may also cause doubts about the safety and impair the reputation of the technology as well. In order to avoid irreversible complications, local authorities should follow the technology and update the regulations where the dermatologists should take an active role.

    Technologies and devices for cosmetic procedures are developing with each passing day. However, increased and unauthorized use of such emerging technologies may also lead to increases in unexpected results and complications as well. Here, we report a case of facial cellulitis after a "beauty parlor" session of skin cleaning with jet stream peeling device in 19-year old female patient for the first time. Complications due to improper and unauthorized use of jet stream peeling devices may also cause doubts about the safety and impair the reputation of the technology as well. In order to avoid irreversible complications, local authorities should follow the technology and update the regulations where the dermatologists should take an active role.

  17. PREFACE: FAIRNESS 2014: FAIR Next Generation ScientistS 2014

    2015-04-01

    FAIRNESS 2014 was the third 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 September 22-27 2014 in Vietri sul Mare, Italy. The topics of the workshops 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 a box to stimulate discussions. The broad physics program at FAIR is reflected in the wide range of topics covered by the workshop: • 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 • New developments in atomic and plasma physics • Special emphasis is put on the experiments CBM, HADES, PANDA, NUSTAR, APPA and related experiments For each of these different areas one invited speaker was selected to give a longer introductory presentation. The write-ups of the talks presented at FAIRNESS 2014 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

  20. Trade Fairs, Markets and Fields

    Moeran, Brian

    2011-01-01

    This working paper takes as its starting point the work of the German economic sociologist, Jens Beckert, and his call for empirical investigations into how intentionally rational actors reach decisions under conditions when they do not know what is best to do. It describes how trade fairs act...... as a framing mechanism that enables participants to come together for the exchange of goods and services and to perceive themselves as acting in a social field. Fairs frame the contacts people make and sustain as networks; the institutional rules and social norms guiding their behaviour there; and the values...... and cognitive frames that they bring to bear and negotiate with other participants. They make actors aware of a ‘mutual correspondence’ in their interpretation of the goods in which they deal and of the social situations in which engage for the sake of such trade. Trade fairs both configure fields and make...

  1. Future Facility: FAIR at GSI

    Rosner, Guenther

    2007-01-01

    The Facility for Antiproton and Ion Research, FAIR, is a new particle accelerator facility to be built at the GSI site in Germany. The research at FAIR will cover a wide range of topics in nuclear and hadron physics, high density plasma and atomic physics, and applications in condensed matter physics and biology. A 1.1 km circumference double ring of rapidly cycling 100 and 300 Tm synchrotrons, will be FAIR's central accelerator system. 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

  11. Fair Exchange in Strand Spaces

    Joshua D. Guttman

    2009-10-01

    Full Text Available Many cryptographic protocols are intended to coordinate state changes among principals. Exchange protocols coordinate delivery of new values to the participants, e.g. additions to the set of values they possess. An exchange protocol is fair if it ensures that delivery of new values is balanced: If one participant obtains a new possession via the protocol, then all other participants will, too. Fair exchange requires progress assumptions, unlike some other protocol properties. The strand space model is a framework for design and verification of cryptographic protocols. A strand is a local behavior of a single principal in a single session of a protocol. A bundle is a partially ordered global execution built from protocol strands and adversary activities. The strand space model needs two additions for fair exchange protocols. First, we regard the state as a multiset of facts, and we allow strands to cause changes in this state via multiset rewriting. Second, progress assumptions stipulate that some channels are resilient-and guaranteed to deliver messages-and some principals are assumed not to stop at certain critical steps. This method leads to proofs of correctness that cleanly separate protocol properties, such as authentication and confidentiality, from invariants governing state evolution. G. Wang's recent fair exchange protocol illustrates the approach.

  15. Toddlers Selectively Help Fair Agents

    Luca Surian

    2017-06-01

    Full Text Available Previous research showed that infants and toddlers are inclined to help prosocial agents and assign a positive valence to fair distributions. Also, they expect that positive and negative actions directed toward distributors will conform to reciprocity principles. This study investigates whether toddlers are selective in helping others, as a function of others’ previous distributive actions. Toddlers were presented with real-life events in which two actresses distributed resources either equally or unequally between two puppets. Then, they played together with a ball that accidentally fell to the ground and asked participants to help them to retrieve it. Participants preferred to help the actress who performed equal distributions. This finding suggests that by the second year children’s prosocial actions are modulated by their emerging sense of fairness.HighlightsToddlers (mean age = 25 months are selective in helping distributors.Toddlers prefer helping a fair rather than an unfair distributor.Toddlers’ selective helping provides evidence for an early sense of fairness.

  19. Cutaneous Paecilomyces lilacinus infection mimicking cellulitis in an immunocompetent patient: Report of a case and review of the literature

    Yen-Ta Chen

    2016-03-01

    Full Text Available Paecilomyces lilacinus, a ubiquitous saprophytic mold found in the environment, is an emerging pathogen that causes localized to severe systemic diseases, especially in immunocompromised patients. Thus far, there are only eight reports on immunocompetent patients with cutaneous P. lilacinus in the English literature. We herein present the case of an 87-year-old immunocompetent Taiwanese man who presented with a progressive, tender, erythematous plaque mimicking cellulitis on the ventral surface of the right forearm for 2 weeks. The patient was initially diagnosed as a case of cellulitis; however, due to unresponsiveness to the treatment for 1 week, we decided to perform skin biopsy and tissue culture. Results of histopathologic analysis, tissue culture, and polymerase chain reaction assay indicated cutaneous P. lilacinus infection. Consequently, systemic antifungal treatment with oral itraconazole (200 mg/d was initiated and the skin lesion resolved after a 4-week treatment.

  20. Association of type 2 diabetes with prolonged hospital stay and increased rate of readmission in patients with lower limb cellulitis.

    2017-01-01

    Lower limb (LL) cellulitis-related hospitalisations are prevalent in type 2 diabetes subjects. We assess its costs and factors associated with length of stay and readmissions. A retrospective case-control study at an urban hospital servicing a multi-ethnic population in New Zealand, where 7% of the adult population is estimated to have diabetes. Admissions with LL cellulitis in 2008-2013 were identified using coding records. Subsequent hospitalisations after 1 month with the same diagnosis were classified as readmissions. Glycaemic control was assessed by HbA1c measured within 6 months of the index admission. There were 4600 admissions with LL cellulitis in 3636 patients, including 719 patients (20%) with type 2 diabetes. Hospital stay was longer for type 2 diabetes patients (median 5.3 vs 3.0 days, P < 0.001), independent of age, ethnicity and HbA1c. Accompanying LL ulceration was more frequent in type 2 diabetes patients (50% vs 17%, P < 0.001); however, admissions remained longer for type 2 diabetes patients without ulceration (median 3.4 vs 2.8 days, P < 0.001). Readmission rates were also higher in type 2 diabetes patients compared to non-diabetes patients (HR 1.7, P < 0.001), even in the absence of ulceration (HR 2.2, P < 0.001). Age, HbA1c and ethnicity did not distinguish those prone to readmissions in the type 2 diabetes cohort. Type 2 diabetes patients accounted for a fifth of all admissions and one third of the estimated costs. A high proportion of patients with type 2 diabetes was admitted with LL cellulitis. They had significantly longer admissions and higher readmission rates. Age, HbA1c and ethnicity did not predict length of stay or recurrence. © 2016 Royal Australasian College of Physicians.

    Full Text Available La celulitis es una inflamación aguda de la dermis y tejido celular subcutáneo de causa bacteriana, que generalmente complica a heridas, úlceras y dermatosis, aunque de manera frecuente no existe sitio de entrada. Se recomienda la realización de cultivo de punción de piel y partes blandas (PPB. Los hemocultivos raramente dan resultados positivos. El objetivo de este trabajo fue determinar la prevalencia de bacteriemia en pacientes internados en nuestra institución con diagnóstico de celulitis. Se analizaron retrospectivamente los registros clínicos de los pacientes con este diagnóstico al ingreso entre junio de 2007 y marzo de 2010. Se evaluaron los datos poblacionales, presencia de comorbilidades, y resultados de los cultivos. En ese período, se internaron 140 pacientes con diagnóstico de celulitis y a todos ellos se les realizó hemocultivo y cultivos de PPB. Setenta y cuatro eran varones (52.8%. La edad promedio: 47.5 ± 19.7 años (rango 16-94. El 40% tuvo cultivos positivos de PPB, en los que el Staphylococcus aureus meticilino resistente (SAMR fue el germen más frecuentemente aislado (35.7%; la prevalencia de bacteriemia fue del 8.6%, en donde el germen más frecuente fue Streptoccocus Beta hemolítico, grupo G (33% del total de hemocultivos positivos.

    Brain microvessels are characterized by specific structure and organization within the neurovascular unit. Through highly selective endothelial junctions, the blood-brain barrier (BBB) controls exchanges of cells, fluids, plasmatic proteins and metabolites between blood and the cerebral compartment. VE-cadherin, a transmembrane protein of endothelial junctions, is of most importance in the vascular integrity. Indeed, its destabilization leads to BBB weakening and also breaking in some patholo...

    After injection in the rat of soluble neptunium salt, the distribution of this element was studied at the subcellular level by electron microscopy and electron probe microanalysis. Abnormal structures have been observed by electron microscopy in the nuclei of hepatocytes, and the same structures have also been observed in the nuclei of the proximal tubules cells of the kidney. These structures are formed of clusters of very small and dense particles, several nanometers in diameter. The clusters are localized in the central part of the nuclei and they are separate from nucleoli and heterochromatin. Electron probe X-ray analysis of this cluster have shown that they contain neptunium associated with phosphorus. In the cell containing neptunium inclusions, other non specific lesions are also observed (nuclear pycnosis, mitochondrial depletion).

  4. Who Can Have Parenteral Antibiotics at Home?: A Prospective Observational Study in Children with Moderate/Severe Cellulitis.

    Ibrahim, Laila F; Hopper, Sandy M; Babl, Franz E; Bryant, Penelope A

    2016-03-01

    The benefits of treating children at home or in an ambulatory setting have been well documented. We aimed to describe the characteristics and evaluate the outcomes of children with moderate/severe cellulitis treated at home with intravenous (IV) ceftriaxone via direct referral from the Emergency Department to a hospital-in-the-home (HITH) program. Patients aged 3 months to 18 years with moderate/severe cellulitis referred from a tertiary pediatric Emergency Department to HITH from September 2012 to January 2014 were prospectively identified. Data collection included demographics, clinical features, microbiological characteristics and outcomes. To ensure home treatment did not result in inferior outcomes, these patients were retrospectively compared with patients who were hospitalized for IV flucloxacillin, the standard-of-care over the same period. The primary outcome was home treatment failure necessitating hospital admission. Secondary outcomes included antibiotic changes, complications, length of stay and cost. Forty-one (28%) patients were treated on HITH and 103 (72%) were hospitalized. Compared with hospitalized patients, HITH patients were older (P antibiotic changes was similar in both groups (5% vs. 7%, P = 0.67), as was IV antibiotic duration (2.3 vs. 2.5 days, P = 0.23). Older children with moderate/severe limb cellulitis without systemic symptoms can be treated at home. To ascertain if this practice can be applied more widely, a comparative prospective, ideally randomized, study is needed.

    entreprises F.Mayo puis par la Geigy Co. a d-abord intéressé l-armée, puis l-agriculture. Dès la fin de la 2(ème) guerre mondiale, des mises en garde furent lancées à propos des effets nocifs du produit (4). Un déclin des populations de grives, d-aigles chauves, d-orfaies et de mammifères consommateurs de poissons fut constaté à partir des années 50 et dénoncé par Rachel Carson dans son célèbre appel du « Silent Spring » de 1962. Bien qu-il soit interdit en Occident depuis les années 70, ce produit a été tellement utilisé et présente une rémanence si longue qu-une contamination ubiquitaire existe aujourd-hui encore. De plus, ce produit continue à être produit aux USA pour être utilisé à des fins de démoustification dans les pays en voie de développement. Il en va de même de l-Hexachlorobenzène (HCB), un autre organochloré dont l-usage est interdit sous nos latitudes, mais reste fréquent dans d-autres pays. Ces deux exemples indiquent que le problème de la contamination continue à nous concerner, même pour des produits dont l-usage est aujourd-hui strictement réglementé ou interdit. Des effets sur la faune semblent encore actuellement devoir être attribués à ces produits. La diminution de la population des phoques dans la mer de Wadden pourrait être due à la forte contamination en composants organochlorés des poissons dont ces phoques se nourrissent (5). Exposé au DDT et à son métabolite dichlorodiphenyldichloroéthylène (DDE), le Seratherodon mossambicus présente une réduction de la sécrétion de cortisol par une action toxique cytospécifique sur l-axe hypothalamo-hypophysaire (6). Des travaux récents ont montré que le DDT et le DDE se lient chez les oiseaux et les mammifères au moyen de liaisons covalentes aux cellules de la zona fasciculata - homologue du tissu interrénal du poisson - induisant des microhémorragies. Cette « défaillance » cortisolique peut s-accompagner d-une perturbation du m

    Le livre de Georges Brown est un livre important pour deux raisons : - Parce qu'il propose à tous les formateurs et enseignants une approche méthodologique de la transmission orale des connaissances. En effet, il ne suffit pas de bien connaître son sujet pour le faire comprendre à son auditoire. Ce livre est conçu pour mener le lecteur pas à pas dans la découverte de son propre style d'explication, de ses points faibles et de ses points forts. - Parce qu'il permet au lecteur, grâce à la pratique des 45 exercices contenus dans l'ouvrage, de faire alterner la réflexion et la performance individuelle avec l'échange d'expériences et l'auto-évaluation des méthodes d'enseignement oral. Ce livre, qui possède toutes les qualités du pragmatisme anglo-saxon, met au service de la formation un outil essentiellement pratique. Il s'adresse donc à tous ceux qui donnent des cours, font des séminaires,ou ont à exposer leurs idées devant un auditoire. EXPLIQUER, C'EST D'ABORD SAVOIR COMMUNIQUER.

  10. The NUSTAR program at FAIR

    Herlert Alexander

    2014-04-01

    Full Text Available The NUSTAR Collaboration brings together several hundred scientists to form one of the four scientific pillars of the future FAIR facility. NUSTAR aims at the exploitation of intense radioactive beams with energies up to 1.5 GeV/u in order to explore nuclei with large neutron or proton excess. The project has evolved over the last years and now reached a state where a large fraction of the core program is financed, partly built, and even ready for operation. With the signing of the FAIR convention in 2010 and the start of construction, the sub-projects in NUSTAR gain momentum and look forward to commissioning and first beams in this decade. The present status of the project will be presented, focusing on the instrumentation to be applied in the various experimental areas behind the Super-FRS fragment separator, which is the central instrument of NUSTAR.

    1975-01-01

    A series of environmental measurements during the Hybla Fair nuclear event were made. Experimenters were unsure of conditions that would be created since there was no closure system and the experiments were close to the source. A variety of temperature, pressure, and load devices were tested. The results will aid in the design and engineering of future close-in diagnostic packages and pipes. (U.S.)

    These proceedings cover the analysis of hadronic resonances in heavy ion collisions. The model used for these studies is the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model. The model will be briefly explained, resonance observables will be highlighted and various kinematical issues will be investigated. Special emphasis will be put on the FAIR energy regime, especially highlighting the Compressed Baryonic Matter (CBM) program.

  15. Fair adaptation to climate change

    Paavola, Jouni; Adger, W. Neil

    2006-01-01

    This article identifies social justice dilemmas associated with the necessity to adapt to climate change, examines how they are currently addressed by the climate change regime, and proposes solutions to overcome prevailing gaps and ambiguities. We argue that the key justice dilemmas of adaptation include responsibility for climate change impacts, the level and burden sharing of assistance to vulnerable countries for adaptation, distribution of assistance between recipient countries and adaptation measures, and fair participation in planning and making decisions on adaptation. We demonstrate how the climate change regime largely omits responsibility but makes a general commitment to assistance. However, the regime has so far failed to operationalise assistance and has made only minor progress towards eliminating obstacles for fair participation. We propose the adoption of four principles for fair adaptation in the climate change regime. These include avoiding dangerous climate change, forward-looking responsibility, putting the most vulnerable first and equal participation of all. We argue that a safe maximum standard of 400-500 ppm of CO 2 concentrations in the atmosphere and a carbon tax of $20-50 per carbon equivalent ton could provide the initial instruments for operationalising the principles.

    2012-01-01

    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.

  17. HOW APPRAISERS DEVELOP FAIR VALUE

    2012-01-01

    Full Text Available Management is responsible for its own financial decisions. If we take into account, that fair value concept was shown in financial crisis as something that does not work anymore in this way; there is a big need to develop it for the future. Non-professional readers of financial statements believe, however, that company financials are the work of the public accounting firm that had signed the audit certificate. The main reason for bringing this point up is that when companies disclose Fair Value (FV information in their financial statements, they are taking responsibility for the values disclosed. Management may often be encouraged to utilize the services of an outside professional, but at the end of the day, the outside appraiser is a hired gun. Although the appraiser has to take responsibility for his own work, hiring the appraiser does not absolve management of its ultimate responsibility. The obverse of this is also true. Management does not have to hire the appraiser to develop any fair value disclosures made in the financial statements. Developing FV information is not recommended as a do-it yourself undertaking, there is nothing in Generally Accepted Accounting Principles (GAAP or Securities Exchange Commission (SEC regulations, however, that requires an outside appraiser.

    2012-07-01

    RUAG Space are developing materials and processing technologies for manufacture of the Next Generation Launcher (NGL) payload fairing, together with the Laboratory of Polymer and Composite Technology at the EPFL, in a project running under the ESA Future Launchers Preparatory Program (FLPP). In this paper the general aims and scope of the project are described, details of the results obtained shall be presented at a later stage. RUAG Space design, develop and manufacture fairings for the European launch vehicles Ariane 5 and VEGA using well proven composite materials and production methods which provide adequate cost/performance ratio for these applications. However, the NGL shall make full use of innovations in materials and process technologies to achieve a gain in performance at a much reduced overall manufacturing cost. NGL is scheduled to become operational in 2025, with actual development beginning in 2014. In this current project the basic technology is being developed and validated, in readiness for application in the NGL. For this new application, an entirely new approach to the fairing manufacture is evaluated.

  19. A rare cause of cellulitis (necrotic arachnidism: a report of two cases

    Tugba Sari

    2014-09-01

    Full Text Available Bites from brown recluse spiders (Loxosceles reclusa result in several clinical manifestations, causing painful, disfiguring necrotic ulcers and, uncommonly, severe systemic effects. We report two cases reports with necrotic arachnidism from Turkey. A 21-year-old man was admitted to our clinic with the complaints of pruritis, redness on his neck. He had a history of spider bite one day ago. A 52-year-old woman had a cellulitis with hemorrhagic lesion and superficial necrosis on her arm and had a history of spider bite one day ago. Based on these clinical and epidemiological findings, a diagnosis of necrotic arachnidism was suspected, and the diagnosis of necrotic arachnidism was confirmed with these typical skin lesions and spiders bites in histories of patients. The outcome of our patients were good after antihistaminic, antibiotic, analgesic and anti-inflammatory treatments. The brown recluse spider is notorious for its necrosisinducing bite. Its venom contains a rare toxin, sphingomyelinase D, which activates the vascular endothelium and initiates a cascade of activation of neutrophils and granulocyte macrophage colony-stimulating factor, resulting in tissue destruction. In many cases, diagnosis of spider bite is very difficult. Therefore, clinical and epidemiological findings, as well as a detailed history, may establish the diagnosis.

  20. Cryptococcosis mimicking cutaneous cellulitis in a patient suffering from rheumatoid arthritis: a case report

    Probst Corina

    2010-08-01

    Full Text Available Abstract Background Cryptococcus neoformans is an encapsulated yeast and the most frequent cryptococcal species found in humans. Cryptococcosis is considered an opportunistic infection as it affects mainly immunosuppressed individuals. In humans, C. neoformans causes three types of infections: pulmonary cryptococcosis, cryptococcal meningitis and wound or cutaneous cryptococcosis. Case Presentation An 81-year-old woman developed severe necrotizing cellulitis on her left arm without any preceding injury. The patient had been treated with systemic corticosteroids over twenty years for rheumatoid arthritis (RA. Skin biopsies of the wound area were initially interpreted as cutaneous vasculitis of unknown etiology. However, periodic acid Schiff staining and smear analysis later revealed structures consistent with Cryptococcus neoformans, and the infection was subsequently confirmed by culture. After the initiation of therapy with fluconazole 400 mg per day the general condition and the skin ulcers improved rapidly and the patient was discharged to a rehabilitation facility. Subsequently surgical debridement and skin grafting were performed. Conclusions Opportunistic infections such as cryptococcosis can clinically and histologically mimic cutaneous vasculitis and have to be investigated rigorously as a differential diagnosis in immunosuppressed patients.

  1. Necrotizing cellulitis with multiple abscesses on the leg caused by Serratia marcescens.

    2016-03-01

    Serratia marcescens is an unusual cause of severe skin infection initially described in immunocompromised patients. We report a case of necrotizing cellulitis of the leg caused by S marcescens in a 68-year-old woman with diabetes mellitus and a history of chronic lymphoedema of the leg. We reviewed the literature and found 49 cases of severe skin infections from S marcescens that included 20 cases of necrotizing fasciitis (NF) as well as 29 cases of severe skin infections without NF (non-NF cases). Patients were immunocompromised in 59% to 70% of cases. The mortality rate was high in NF cases (60%) versus non-NF cases (3%). Surgery was required in 95% of NF cases and in 24% of non-NF cases. The other clinical manifestations of S marcescens skin infection reported in the literature included disseminated papular eruptions in patients infected with human immunodeficiency virus with folliculitis on the trunk. Serratia marcescens is naturally resistant to amoxicillin alone and amoxicillin associated with clavulanic acid. Broad-spectrum antibiotics are indicated to treat S marcescens skin infections, and surgery should be promptly considered in cases of severe skin infections if appropriate antibiotic therapy does not lead to rapid improvement.

  2. Acute Truncal Lymphedema Secondary to Axillary Metastatic Melanoma Presenting Like Cellulitis

    Shelley J. E. Hwang

    2017-01-01

    Full Text Available There are reported cases of diphencyprone used in treating cutaneous metastases of melanoma. Here, we report a patient with previous primary melanoma on his left back treated with surgical excision and lymphadenectomy, followed by radiotherapy for the recurrent tumor on the primary site. Despite radiotherapy and treatment with dabrafenib and trametinib, in-transit metastases have developed and topical diphencyprone was applied to these metastases. Six weeks later, the patient developed fever and a spreading erythematous tender indurated plaque covering the left side of the body including axillae, back, and flank, clinically suggestive of cellulitis. Systemic antibiotic therapy did not improve the condition and a biopsy showed sparse lymphocytic infiltrate. With the diagnosis of possible acute lymphedema, a CT scan was requested that showed significant axillary lymph node metastasis. The fever was considered secondary to dabrafenib and trametinib therapy. This case highlights that, in patients with lymphadenectomy, atypical forms of lymphedema on the body may appear. Truncal lymphedema is an infrequent event.

  3. Hospital costs for patients with lower extremity cellulitis: a retrospective population-based study.

    Challener, Douglas; Marcelin, Jasmine; Visscher, Sue; Baddour, Larry

    2017-12-01

    Hospital admissions for non-purulent lower extremity cellulitis (NLEC) are common and can be prolonged and costly. Newer treatment options and preventive strategies are expected to result in cost savings before implementation, but few studies have quantified the cost of conventional treatment. Using the Rochester Epidemiology Project, the incidence of NLEC in Olmsted County, MN in 2013 was 176.6 per 100,000 persons. The subset of patients who required hospitalization for NLEC in 2013 was determined. Hospital admissions were analyzed retrospectively using standardized cost analysis within several relevant categories. Thirty-four patients had an average hospital length of stay of 4.7 days. The median total inpatient cost was $7,341. The median cost per day was $2,087, with 49% due to room and board. Antibiotics administered for treatment of NLEC contributed a median cost of $75 per day of hospitalization, and laboratory and imaging test costs were $73 and $44, respectively, per day of hospitalization. Hospitalizations for NLEC can be costly and prolonged with room and board accounting for much of the cost. Therefore, newer management strategies should seek to reduce hospital length of stay and/or avoid inpatient admission to reduce cost.

  4. The impact of dermatology consultation on diagnostic accuracy and antibiotic use among patients with suspected cellulitis seen at outpatient internal medicine offices: a randomized clinical trial.

    Arakaki, Ryan Y; Strazzula, Lauren; Woo, Elaine; Kroshinsky, Daniela

    2014-10-01

    Cellulitis is a common and costly problem, often diagnosed in the outpatient setting. Many cutaneous conditions may clinically mimic cellulitis, but little research has been done to assess the magnitude of the problem. To determine if obtaining dermatology consultations in the outpatient primary care setting could assist in the diagnosis of pseudocellulitic conditions and reduce the rate of unnecessary antibiotic use. Nonblinded randomized clinical trial of competent adults who were diagnosed as having cellulitis by their primary care physicians (PCPs), conducted at outpatient internal medical primary care offices affiliated with a large academic medical center. Outpatient dermatology consultation. Primary outcomes were final diagnosis, antibiotic use, and need for hospitalization. A total of 29 patients (12 male and 17 female) were enrolled for participation in this trial. Nine patients were randomized to continue with PCP management (control group), and 20 patients were randomized to receive a dermatology consultation (treatment group). Of the 20 patients in the dermatology consultation group, 2 (10%) were diagnosed as having cellulitis. In the control group, all 9 patients were diagnosed as having cellulitis by PCPs, but dermatologist evaluation determined that 6 (67%) of these patients had a psuedocellulitis rather than true infection. All 9 patients (100%) in the control group were treated for cellulitis with antibiotics vs 2 patients (10%) in the treatment group (P Dermatology consultation in the primary care setting improves the diagnostic accuracy of suspected cellulitis and decreases unnecessary antibiotic use in patients with pseudocellulitic conditions. Obtaining an outpatient dermatology consultation may be a cost-effective strategy that improves quality of care. clinicaltrials.gov Identifier:NCT01795092.

  5. Children develop a veil of fairness.

    Shaw, Alex; Montinari, Natalia; Piovesan, Marco; Olson, Kristina R; Gino, Francesca; Norton, Michael I

    2014-02-01

    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.

  8. Strategy intervention for the evolution of fairness.

    Yanling Zhang

    Full Text Available The 'irrational' preference for fairness has attracted increasing attention. Although previous studies have focused on the effects of spitefulness on the evolution of fairness, they did not consider non-monotonic rejections shown in behavioral experiments. In this paper, we introduce a non-monotonic rejection in an evolutionary model of the Ultimatum Game. We propose strategy intervention to study the evolution of fairness in general structured populations. By sequentially adding five strategies into the competition between a fair strategy and a selfish strategy, we arrive at the following conclusions. First, the evolution of fairness is inhibited by altruism, but it is promoted by spitefulness. Second, the non-monotonic rejection helps fairness overcome selfishness. Particularly for group-structured populations, we analytically investigate how fairness, selfishness, altruism, and spitefulness are affected by population size, mutation, and migration in the competition among seven strategies. Our results may provide important insights into understanding the evolutionary origin of fairness.

  10. Fair play in energy policy decisions: Procedural fairness, outcome fairness and acceptance of the decision to rebuild nuclear power plants

    Visschers, Vivianne H.M.; Siegrist, Michael

    2012-01-01

    To raise public acceptance of new energy policies, promoting the fairness of the outcomes and of the decision-making procedure has been suggested. Very few studies have examined the role of fairness in public acceptance of rebuilding nuclear power plants. Therefore, using a large mail survey, we investigated the public’s acceptance of the decision to rebuild nuclear power plants in Switzerland by 2020. The study examined the influence of procedural fairness and outcome fairness on the acceptance of this decision, as well as other factors such as risk perception and benefit perception. Additionally, we investigated the moderating influence of general attitudes towards nuclear power on the relation between fairness and decision acceptance. Results indicated that outcome fairness strongly increased decision acceptance, along with general attitudes towards nuclear power and perceived economic benefits. Procedural fairness had only a small impact on decision acceptance. The influence of fairness on decision acceptance did not seem to depend on general nuclear attitudes. Our findings imply that, in the case of rebuilding nuclear power plants, perceived benefits and outcome fairness are important determinants of acceptance of the decision, while procedural fairness only has a limited impact. - Highlights: ► We investigated the role of fairness in the acceptance of a nuclear policy decision. ► Outcome fairness strongly influenced decision acceptance regarding nuclear power plants. ► The role of procedural fairness was relatively small in this respect. ► Also, nuclear attitudes and perceived economic benefits affected decision acceptance. ► Outcome fairness seems more relevant for decision acceptance than procedural fairness.

    Many have argued that measuring financial instruments at fair value might not reflect firms’ financial condition. Prior study finds that managers manipulate the “disclosure” of fair value measurement (Song et al. 2010). In this study, we attempt to provide evidence regarding manager’s incentive to manipulate the disclosure of fair value measurements by examining whether the disclosure of less relevant fair value measurement is related to the odds of earnings management.

  6. Volatility as a downside of fairness

    Leibfried, Peter; Zimmermann, Marc-Daniel

    2008-01-01

    Accounting Standards increasingly require financial instruments such as stocks, derivatives and structured products to be measured at fair value. As fair values represent a financial instrument's market value, price fluctuations find their way into financial statements. Even though fair value measurement provides useful information about the current value of a corporation's assets, it also increases the volatility of earnings.

  7. Problems presented by the filtration and sampling of aerosols in the atomic energy programme; Problemes poses par la filtration et le prelevement des aerosols dans le cadre de l'energie atomique

    Cochinal, R [Commissariat a l' Energie Atomique, Saclay (France).Centre d' Etudes Nucleaires

    1959-07-01

    The maximum permissible limits for radioactive aerosols are much lower than those for aerosols encountered in the non-nuclear industries. These limits depend on numerous factors such as: nature of the radiation, half-life, etc. The radioactive aerosols can be prepared by various methods. The filtering of the air in high activity laboratories or in plutonium treatment factories necessitates an installation consisting of: - aspiration filters, - extraction filters of very high efficiency (those used for {alpha} emitter cells: designed to be replaced without incurring contamination risks; those used for {gamma} emitter cells: designed to be replaced by remote control). The filtering in nuclear reactors is also effectuated by filter papers: - the G1 reactor with open circuit: the air coolant is entirely filtered at the entry and on leaving; - the G2, G3 and EDF1 reactors with closed circuits: filtering under pressure of a small portion of the coolant gas. (author) [French] Les limites maxima permises des aerosols radioactifs sont beaucoup plus faibles que celles des aerosols rencontres dans l'industrie classique.

    2015-01-01

    We develop a theory which applies to any market dynamics that satisfy a fair market assumption on the nullity of the average profit of simple market making strategies. We show that for any such fair market, there exists a martingale fair price which corresponds to the average liquidation value (at the ask or the bid) of an infinitesimal quantity of stock. We show that this fair price is a natural reference price to compute the ex post gain of limit orders. Using only the fair market assumptio...

    During the Frankfurt book fair last October, the CERN stand drew quite the crowd. Director-General Rolf Heuer was there to promote CERN’s mission and the "LHC: the Large Hadron Collider" book. He met a lot of visitors and for one of them there was also a nice follow-up…   Marcus and his father visiting the LINAC facility. Fifteen year-old Marcus lives in Lauterecken near Frankfurt. The popular book fair last autumn was for him a nice opportunity to get in touch with the CERN environment. Inspired by the stand and what the CERN people were describing, he started to ask more and more questions… So many, that Rolf Heuer decided to invite him to come to CERN and find out some of the answers for himself. A few weeks later, while recovering from an exciting visit to the ATLAS underground cavern and other CERN installations with a cup of tea in Restaurant 1, Marcus shared his enthusiasm about the Organization: “When I was younger, my moth...

    As hospital crowding has increased, more patients have ended up boarding in the emergency department (ED) awaiting their inpatient beds. To the best of our knowledge, no study has compared the quality of care of boarded and nonboarded patients. This study sought to examine whether being a boarded patient and boarding longer were associated with more delays, medication errors, and adverse events among ED patients admitted with chest pain, pneumonia, or cellulitis. This study was a retrospective cohort design in which data collection was accomplished via medical record review from two urban teaching hospitals. Patients admitted with chest pain, pneumonia, or cellulitis between August 2004 and January 2005 were eligible for inclusion. Our outcomes measures were: 1) delays in administration of home medications, cardiac enzyme tests, partial thromboplastin time (PTT), and antibiotics; 2) medication errors; and 3) adverse events or near misses. Primary independent variables were boarded status, boarding time, and boarded time interval. Multiple logistic regression models controlling for patient, ED, and hospital characteristics were used. A total of 1,431 patient charts were included: 811 with chest pain, 387 with pneumonia, and 233 with cellulitis. Boarding time was associated with an increased odds of home medication delays (adjusted odds ratio [AOR] = 1.07, 95% confidence interval [CI] = 1.05 to 1.10), as were boarded time intervals of 12, 18, and 24 hours. Boarding time also was associated with lower odds of having a late cardiac enzyme test (AOR = 0.93, 95% CI = 0.88 to 0.97). Boarding was associated with home medication delays, but fewer cardiac enzyme test delays. Boarding was not associated with delayed PTT checks, antibiotic administration, medication errors, or adverse events/near misses. These findings likely reflect the inherent resources of the ED and the inpatient units. © 2011 by the Society for Academic Emergency Medicine.

    Full Text Available Introduction: Comparative effectiveness and efficacy research for analysis and practice (CEERAP was performed to assess the effects of penicillin-based versus erythromycin-based antibiotic treatments in patients with skin and soft tissue infections (SSTIs including cellulitis, impetigo, and erysipelas. Because SSTIs, especially orofacial cellulitis, are volatile infectious diseases of a life-threatening nature, research on the most efficacious remedies is necessary. Methods: The stringent bibliome yielded three systematic reviews, which were examined for quality of research synthesis protocol and clinical relevance. Results: The sample size of three, rendered the statistical analyses and cumulative meta-analysis problematic. Conclusion: The systematic review outlined here should aid in increasing clinical awareness, improving patient health literacy, and promoting consensus of the best evidence base (BEB to mitigate the threat of sepsis and potential death caused by cellulitis infections.

Toute consommation entraîne un risque et toutes les substances, en fonction de la fréquence de leur consommation, ont le potentiel d' engendrer une dépendance. Étant donné que rien ne prouve l'effet bénéfique de la consommation de ces substances, que la consommation soit occasionnelle ou bien au gré des situations, nous croyons que les spécialistes en addictologie doivent faire partie des équipes rattachées aux centres ou services médicaux. Consommer ces substances c' est fuir les problèmes et non pas les affronter. Les stratégies qui aident à faire face aux expériences de vie négatives et à renforcer les capacités de les surmonter seraient, entre autres, la technique d' exposition, la planification de surmonter les difficultés, la sollicitation du soutien social, l' acquisition de la maîtrise de soi, l' acceptation, l' acquisition des techniques de contrôle du stress.

  19. Production of hypernuclei at FAIR

    Gaitanos, Theodoros; Larionov, Alexei; Mosel, Ulrich [Institut fuer Theoretische Physik, Universitaet Giessen (Germany)

    2011-07-01

    The strangeness sector of the strong interaction is important for our knowledge on, e.g., nuclear astrophysics. It is still a widely debated topic of current research. Hypernuclear production in heavy-ion collisions and anti p-nucleus collisions offers the opportunity to investigate the hyperon-nucleon and hyperon-hyperon interaction inside a hadronic environment in terrestrial laboratories. We study the formation of fragments with and without strangeness contents in the framework of a dynamical transport model (Giessen Boltzmann-Uehling- Uhlenbeck, GiBUU) and a statistical approach (Statistical Multifragmentation Model, SMM) of fragment formation. We use a coalescence picture for the production of single-{Lambda} and double-{Lambda} hypernuclei, and provide theoretical estimates on their spectra and inclusive cross sections in heavy-ion collisions and anti p induced reactions, relevant for HypHI and PANDA experiments at FAIR.

  20. The PANDA experiment at FAIR

    Bussa, M.P.

    2005-01-01

    The approved FAIR upgrade of the GSI facility in Darmstadt, Germany, includes the construction of a High Energy Storage Ring (HESR) for high intensity, phase space cooled antiprotons with momenta up to 15 GeV/c. A wide physics program is planned at this facility to investigate fundamental questions of hadron and nuclear physics in interactions of antiprotons with nucleons and nuclei. To serve the many experiments planned at this new facility, an universal, modular, hermetic spectrometer called PANDA (Proton ANtiproton Detector Array) is planned. This talk presents an overview of the physics program pursued by this project and of the PANDA detector system. The feasibility of measurements in the sector of spin degrees of freedom of quarks will be also discussed. (author)

    Extranodal natural killer (NK)/T-cell lymphoma is a very rare and aggressive disease characterized histopathologically by an Epstein-Barr virus (EBV)-positive atypical lymphoid cytotoxic infiltrate, extensive vascular destruction, and prominent tissue necrosis. It commonly shows cutaneous lesions that primarily or secondarily mimic cellulitis at the primary site. We report on a very rare case of extranodal NK/T-cell lymphoma, nasal type of skin/soft tissue, in a 64-year-old man, and describe the radiological findings.

    Full Text Available L’effet des vitamines B12, B9 et B6 sur la fragilité osmotique des érythrocytes humains a été exploré in vitro. De fortes concentrations de vitamines B12 et B6 ont protégé les érythrocytes de l’hémolyse hypotonique, avec une protection maxima atteinte respectivement à 10 et 500 µg/ml. A concentrations plus faibles, cependant, ces vitamines ont favorisé grandement l’hémolyse hypotonique. Par contre, la vitamine B9 a montré uniquement un effet hémolytique de 4 à 200 µg/ml. Cet effet peut être expliqué par la nature acide de la molécule. L’effet nul sur la fragilité osmotique de deux vitamines antagonistes, peut probablement être expliqué par l’antagonisme partiel ou par la présence de ces deux vitamines simultanément: ces dernières se lient en quantités appréciables à la cellule intacte de même qu’à l’hémolysat et il y’ a compétition mutuelle entre ces vitamines et leur transport.

  10. Ultrahigh-rate supercapacitors with large capacitance based on edge oriented graphene coated carbonized cellulous paper as flexible freestanding electrodes

    Ren, Guofeng; Li, Shiqi; Fan, Zhao-Xia; Hoque, Md Nadim Ferdous; Fan, Zhaoyang

    2016-09-01

    Large-capacitance and ultrahigh-rate electrochemical supercapacitors (UECs) with frequency response up to kilohertz (kHz) range are reported using light, thin, and flexible freestanding electrodes. The electrode is formed by perpendicularly edge oriented multilayer graphene/thin-graphite (EOG) sheets grown radially around individual fibers in carbonized cellulous paper (CCP), with cellulous carbonization and EOG deposition implemented in one step. The resulted ∼10 μm thick EOG/CCP electrode is light and flexible. The oriented porous structure of EOG with large surface area, in conjunction with high conductivity of the electrode, ensures ultrahigh-rate performance of the fabricated cells, with large areal capacitance of 0.59 mF cm-2 and 0.53 mF cm-2 and large phase angle of -83° and -80° at 120 Hz and 1 kHz, respectively. Particularly, the hierarchical EOG/CCP sheet structure allows multiple sheets stacked together for thick electrodes with almost linearly increased areal capacitance while maintaining the volumetric capacitance nearly no degradation, a critical merit for developing practical faraday-scale UECs. 3-layers of EOG/CCP electrode achieved an areal capacitance of 1.5 mF cm-2 and 1.4 mF cm-2 at 120 Hz and 1 kHz, respectively. This demonstration moves a step closer to the goal of bridging the frequency/capacitance gap between supercapacitors and electrolytic capacitors.

    Full Text Available Les mobilités pendulaires semblent être en augmentation en Europe depuis une dizaine d’années. Cette croissance du temps passé à se déplacer amène à remettre en question la conjecture de Zahavi et apparaît relativement inexplicable en regard du paradigme classique de l’acteur rationnel traditionnellement utilisé dans le champ des transports. Si, dans la littérature, les temps de déplacements sont principalement expliqués par le contexte résidentiel, la forme urbaine et le travail, ce cadre explicatif ne dit rien des processus de décision eux-mêmes qui amènent aux pendularités intensives.À partir d’une enquête qualitative menée auprès de pendulaires français, suisses et belges, cette contribution propose d’analyser les arbitrages et les éléments déterminants des processus de la grande pendularité. Les mobilités quotidiennes pendulaires apparaissent comme le résultat de compromis entre activité professionnelle, attachement résidentiel et choix de vie et prennent ainsi la forme de stratégies de conciliation entre vie privée et vie professionnelle. Ces mobilités spatiales permettent alors paradoxalement la préservation des ancrages résidentiels, sociaux et familiaux.Roots and wings. Long-distance commuting patterns, or how to conciliate professional and personal lifeLong-distance commuting patterns appear to be increasing in Europe over the last ten years. These raising mobility patterns lead to reappraise the Zahavi conjecture and appear largely inexplicable by the classical rational actor paradigm traditionally used in transportation research. In literature, commuting is mainly explained by residential contexts, urban forms and job. Nevertheless this theoretical frame says little about the decision-making processes themselves. Based on a qualitative survey conducted in three European countries - France, Belgium and Switzerland – among a population of high commuters, this paper proposes an analysis of

  13. Genotypes and pathogenicity of cellulitis isolates reveal traits that modulate APEC virulence.

    Nicolle Lima Barbieri

    Full Text Available We characterized 144 Escherichia coli isolates from severe cellulitis lesions in broiler chickens from South Brazil. Analysis of susceptibility to 15 antimicrobials revealed frequencies of resistance of less than 30% for most antimicrobials except tetracycline (70% and sulphonamides (60%. The genotyping of 34 virulence-associated genes revealed that all the isolates harbored virulence factors related to adhesion, iron acquisition and serum resistance, which are characteristic of the avian pathogenic E. coli (APEC pathotype. ColV plasmid-associated genes (cvi/cva, iroN, iss, iucD, sitD, traT, tsh were especially frequent among the isolates (from 66.6% to 89.6%. According to the Clermont method of ECOR phylogenetic typing, isolates belonged to group D (47.2%, to group A (27.8%, to group B2 (17.4% and to group B1 (7.6%; the group B2 isolates contained the highest number of virulence-associated genes. Clonal relationship analysis using the ARDRA method revealed a similarity level of 57% or higher among isolates, but no endemic clone. The virulence of the isolates was confirmed in vivo in one-day-old chicks. Most isolates (72.9% killed all infected chicks within 7 days, and 65 isolates (38.1% killed most of them within 24 hours. In order to analyze differences in virulence among the APEC isolates, we created a pathogenicity score by combining the times of death with the clinical symptoms noted. By looking for significant associations between the presence of virulence-associated genes and the pathogenicity score, we found that the presence of genes for invasins ibeA and gimB and for group II capsule KpsMTII increased virulence, while the presence of pic decreased virulence. The fact that ibeA, gimB and KpsMTII are characteristic of neonatal meningitis E. coli (NMEC suggests that genes of NMEC in APEC increase virulence of strains.

    Emergency department visits for skin infections in the United States have increased with the emergence of methicillin-resistant Staphylococcus aureus (MRSA). For cellulitis without purulent drainage, β-hemolytic streptococci are presumed to be the predominant pathogens. It is unknown if antimicrobial regimens possessing in vitro MRSA activity provide improved outcomes compared with treatments lacking MRSA activity. To determine whether cephalexin plus trimethoprim-sulfamethoxazole yields a higher clinical cure rate of uncomplicated cellulitis than cephalexin alone. Multicenter, double-blind, randomized superiority trial in 5 US emergency departments among outpatients older than 12 years with cellulitis and no wound, purulent drainage, or abscess enrolled from April 2009 through June 2012. All participants had soft tissue ultrasound performed at the time of enrollment to exclude abscess. Final follow-up was August 2012. Cephalexin, 500 mg 4 times daily, plus trimethoprim-sulfamethoxazole, 320 mg/1600 mg twice daily, for 7 days (n = 248 participants) or cephalexin plus placebo for 7 days (n = 248 participants). The primary outcome determined a priori in the per-protocol group was clinical cure, defined as absence of these clinical failure criteria at follow-up visits: fever; increase in erythema (>25%), swelling, or tenderness (days 3-4); no decrease in erythema, swelling, or tenderness (days 8-10); and more than minimal erythema, swelling, or tenderness (days 14-21). A clinically significant difference was defined as greater than 10%. Among 500 randomized participants, 496 (99%) were included in the modified intention-to-treat analysis and 411 (82.2%) in the per-protocol analysis (median age, 40 years [range, 15-78 years]; 58.4% male; 10.9% had diabetes). Median length and width of erythema were 13.0 cm and 10.0 cm. In the per-protocol population, clinical cure occurred in 182 (83.5%) of 218 participants in the cephalexin plus trimethoprim

    2012-01-01

    The PANDA detector will be installed at FAIR to enterprise a long-term, wide-spectrum physics program in the strong interaction framework. The detector will be installed at the HESR accumulation ring, which will provide an anti-proton beam of unprecedented luminosity and momentum definition. The beam will interact with an internal target. The detector has been designed to allow a 4π coverage around the interaction region. Due to the relatively high energy of the beam, up to 15 GeV, PANDA will feature two magnetic spectrometers: the target spectrometer (TS), with a superconducting solenoid and covering the interaction region, and a forward spectrometer (FS), with a normal-conducting dipole and covering the small angles region. Since the physics program is wide and the requirements on the various subsystems are different, the detector has been designed to be as flexible as possible. The complete detector will be described in detail, both from the viewpoint of the proposed techniques and from the viewpoint of the expected performances. An overview of the status of various components of the detector will be presented, too.

The code incorporates finite element based thermomechanical module, physically based fission gas release module and relevant models for modelling fuel related phenomena, such as, pellet cracking, densification and swelling, radial flux redistribution across the pellet due to the build up of plutonium near the pellet surface, pellet clad mechanical interaction/stress corrosion cracking (PCMI/SSC) failure of sheath etc. The code follows the established principles of fuel rod analysis programmes, such as coupling of thermal and mechanical solutions along with the fission gas release calculations, analysing different axial segments of fuel rod simultaneously, providing means for performing local analysis such as clad ridging analysis etc. The modular nature of the code offers flexibility in affecting modifications easily to the code for modelling MOX fuels and thorium based fuels. For performing analysis of fuel rods subjected to very long power histories within a reasonable amount of time, the code has been parallelised and is commissioned on the ANUPAM parallel processing system developed at Bhabha Atomic Research Centre (BARC).

  4. Fairness through Transparency: The Influence of Price Transparency on Consumer Perceptions of Price Fairness

    Sandra Rothenberger

    2015-01-01

    This study proposes that price transparency is a significant factor affecting customer judgments of the fairness of sellers’ prices. Cognitive judgments of fairness require a certain amount of information processing; therefore, the level of transparency and the amount of price information affect fairness judgments. The more clear information consumers possess concerning seller prices, the more positive the judgment will be. Customer price fairness judgment is an effective measurement for the ...

  15. FAIR VALUE ACCOUNTING AND EARNINGS MANAGEMENT

    Pei-Hui Hsu

    2016-04-01

    Full Text Available Many have argued that measuring financial instruments at fair value might not reflect firms’ financial condition. Prior study finds that managers manipulate the “disclosure” of fair value measurement (Song et al. 2010. In this study, we attempt to provide evidence regarding manager’s incentive to manipulate the disclosure of fair value measurements by examining whether the disclosure of less relevant fair value measurement is related to the odds of earnings management. We find that firms with more Level 3 assets and liabilities (i.e., less value relevant fair value measurement are more likely to recognize positive unrealized gains to meet or beat analyst forecast target. In addition, we find that only firms with weak corporate governance disclose more Level 3 fair value liabilities and recognize unrealized gains into reported earnings to meet or beat analyst forecast target. This evidence suggests that managers manipulate the disclosure of fair value measurement in order to manage reported earnings via the adoption of fair value option.

  16. Fair Optimization and Networks: A Survey

    Wlodzimierz Ogryczak

    2014-01-01

    Full Text Available Optimization models related to designing and operating complex systems are mainly focused on some efficiency metrics such as response time, queue length, throughput, and cost. However, in systems which serve many entities there is also a need for respecting fairness: each system entity ought to be provided with an adequate share of the system’s services. Still, due to system operations-dependant constraints, fair treatment of the entities does not directly imply that each of them is assigned equal amount of the services. That leads to concepts of fair optimization expressed by the equitable models that represent inequality averse optimization rather than strict inequality minimization; a particular widely applied example of that concept is the so-called lexicographic maximin optimization (max-min fairness. The fair optimization methodology delivers a variety of techniques to generate fair and efficient solutions. This paper reviews fair optimization models and methods applied to systems that are based on some kind of network of connections and dependencies, especially, fair optimization methods for the location problems and for the resource allocation problems in communication networks.

    Dalley, Simon; Shepherd, Karen; Reisch, Joan

    2017-01-01

    Research misconduct has become an important matter of concern in the scientific community. The extent to which such behavior occurs early in science education has received little attention. In the current study, using the web-based data collection program REDCap, we obtained responses to an anonymous and voluntary survey about science fair from 65 high school students who recently competed in the Dallas Regional Science and Engineering Fair and from 237 STEM-track, post-high school students (undergraduates, 1st year medical students, and 1st year biomedical graduate students) doing research at UT Southwestern Medical Center. Of the post-high school students, 24% had competed in science fair during their high school education. Science fair experience was similar overall for the local cohort of Dallas regional students and the more diverse state/national cohort of post-high school students. Only one student out of 122 reported research misconduct, in his case making up the data. Unexpectedly, post-high school students who did not participate in science fair anticipated that carrying out science fair would be much more difficult than actually was the case, and 22% of the post-high school students anticipated that science fair participants would resort to research misconduct to overcome obstacles. No gender-based differences between students’ science fair experiences or expectations were evident. PMID:28328976

  20. FAIR VALUE IMPLICATIONS ON ROMANIAN CAPITAL MARKET

    Ciprian-Dan COSTEA

    2014-12-01

    Full Text Available Fair value generated intense debate during the last years, as the financial turmoil influenced many economies and capital markets, including the Romanian ones, too. Some researchers and professionals consider fair value in charge with the financial crisis and they ask for historical cost accounting basis for financial reporting. Fair value has its supporters, too. They consider that fair value reflects the effects of changes in market conditions when they take place, and accounting information is more reliable in this framework. Following recent regulations, Romanian entities activating on capital market as investors in capital market instruments, or whose shares are traded on a regulated market, must prepare their individual financial statements in accordance with the International Financial Reporting Standards. The study provides some conclusions that could enlarge the utility of fair value related to entities that activate on Romanian capital market.

  1. VALUATION TECHNIQUES USED IN FAIR VALUE MEASUREMENT

    Cristina-Aurora, BUNEA-BONTAS

    2013-12-01

    Full Text Available Valuation of assets and liabilities involves significant judgements and estimates, especially when fair value measurement is required. Currently, IFRS 13 Fair Value Measurement offers a single and more comprehensive source of guidance that is applied to almost all fair value estimates. When measuring fair value of fixed assets, intangible assets, specified financial assets or liabilities, different valuation techniques may be used: the market approach, the cost approach and the income approach. This article reviews these techniques and points out that different valuation practices may provide different results depending on the item being fair valued and on the inputs used. Also it emphasizes that, in particular circumstances, there is the possibility that a certain technique may be more appropriate than other.

  2. Measuring and Controlling Fairness of Triangulations

    Jiang, Caigui

    2016-09-30

    The fairness of meshes that represent geometric shapes is a topic that has been studied extensively and thoroughly. However, the focus in such considerations often is not on the mesh itself, but rather on the smooth surface approximated by it, and fairness essentially expresses a mesh’s suitability for purposes such as visualization or simulation. This paper focusses on meshes in the architectural context, where vertices, edges, and faces of meshes are often highly visible, and any notion of fairness must take new aspects into account. We use concepts from discrete differential geometry (star-shaped Gauss images) to express fairness, and we also demonstrate how fairness can be incorporated into interactive geometric design of triangulated freeform skins.

  4. Indian participation in FAIR accelerator facility

    Sur, Amitava

    2015-01-01

    India is a founder member of the FAIR-GmbH, the upcoming International Accelerator Facility at Darmstadt, Germany. Indian participation at FAIR is being funded jointly by the Department of Science and Technology (DST) and the Department of Atomic Energy (DAE). Indo- FAIR Coordination Centre at Bose Institute (BI-IFCC) is coordinating the Indian efforts of both in-kind contribution as well as experimental programmes at FAIR. FAIR aims for beams of stable and unstable nuclei as well as antiprotons in a wide range of intensities and energies. A superconducting double-synchrotron SIS100/300 with a circumference of 1,100 meters and with magnetic rigidities of 100 and 300 Tm, respectively, is at the heart of the FAIR accelerator facility. The existing GSI accelerators UNILAC and SIS18 will serve as an injector. Adjacent to the large double- synchrotron is a complex system of storage- cooler rings and experiment stations, including a superconducting nuclear fragment separator (Super-FRS) and an antiproton production target. FAIR will supply rare isotope beams (RIBs) and antiproton beams. In FAIR accelerator facility up to four research programs can be run in a parallel mode. The multidisciplinary research program covers the fields of QCD studies with cooled beams of antiprotons, nucleus nucleus collisions at highest baryon density, nuclear structure and nuclear astrophysics investigations with nuclei far off stability, high density plasma physics, atomic and material science studies, radio-biological and other application-oriented studies will contribute in providing in-kind items both for the accelerator and the experiments. As per current plans Indian in kind contributions include: Power Converters, Superconducting Magnets, Beam Stopper, Vacuum Chamber. A short sample from an Indian Industry has been tested successfully at FAIR. Indian participation in building the accelerator components for FAIR is presented

    2015-03-01

    Full Text Available The main provisions of IFRS 13 «Fair Value Measurement» have been researched as well as its critical analysis has been conducted. Comparison of the previous and the new definition of the concept «fair value» has been done on the basis of what the shortcomings of the previous definition have been highlighted, the characteristic features and advantages of new definition from IFRS 13 «Fair Value Measurement» have been outlined. It has been proved that new interpretation of the concept of «fair value» is narrower and more accurate than the previous, it clarifies the subject matter, subjects of transactions, as well as the date of its execution. The scheme of estimation at fair value as well as model of fair value determination according to IFRS 13 «Fair Value Measurement» has been presented. Methods of measurement at fair value and the fair value hierarchy have been researched. Some disadvantages of provisions of IFRS 13 «Fair Value Measurement» on the basis of its analysis have been highlighted, uncertainty is essential among them in which fair value should be applied.

  9. OGM Diffusion des OGM et impact pour les agriculteurs : quels sont les liens ?

    Lemarie Stéphane

    2001-05-01

    Full Text Available Les OGM actuellement sur le marché présentent des innovations sur des fonctions de protection des plantes. Selon les problèmes de protection des plantes, les gains des agriculteurs liés à l’adoption des OGM sont très variables. Cette hétérogénéité pose d’importants problèmes méthodologiques pour pouvoir estimer correctement la distribution des gains pour l’ensemble des agriculteurs. Une synthèse de plusieurs études américaines est réalisée ici et met bien en évidence la diversité des méthodes utilisées, chacune d’elles présentant ses avantages et ses limites. Globalement, si la diffusion des OGM est un fait indéniable, les études ne permettent pas de tirer des conclusions aussi nettes quant à l’impact des OGM pour tous les agriculteurs qui adoptent ces produits, et cela en particulier pour le soja. Cette absence de conclusion s’explique en grande partie par la difficulté à mesurer certains facteurs qui influencent le comportement d’adoption, comme par exemple la simplification de la conduite des cultures. En contrepartie, il faut noter que les études présentées ici ne prennent pas en compte un certain nombre d’effets indirects qui peuvent faire diminuer les gains des agriculteurs.

    Acute bacterial cellulitis of the leg (erysipelas) is a common problem involving considerable morbidity in dermatology practice in Africa. Previous studies conducted in Europe and North Africa have highlighted lymphoedema and toe-web intertrigo as independent factors associated with leg erysipelas. The aim of this case-control study was to identify risk factors associated with leg erysipelas in sub-Saharan Africa, within a different socio-economic and culture context. We conducted a prospective case-control study in hospital dermatology departments in 8 sub-Saharan African countries over a 12-month period (October 2013 to September 2014). Each case of acute leg cellulitis was matched with 2 controls for age (±5 years) and sex. We analysed the general and local factors. During the study period, 364 cases (223 female, 141 male) were matched with 728 controls. The mean age was 42.15±15.15 years for patients and 42.11±36 years for controls. Multivariate analysis showed the following to be independent risk factors associated with leg erysipelas in our study: obesity (odds ratio [OR]=2.82 ; 95% confidence interval: 2.11-3.76), lymphoedema (OR=3.87, 95%CI: 2.17-6.89), voluntary cosmetic depigmentation (OR=4.29, 95%CI: 2.35-7.83), neglected traumatic wound (OR=37.2, 95%CI: 24.9-57.72) and toe-web intertrigo (OR=37.86, 95%CI: 22.27-64.5). The results of this study confirms the major role of local risk factors (toe-web intertrigo, lymphoedema) previously identified in other geographical settings. However, the originality of our study consists of the identification of voluntary cosmetic depigmentation as a risk factor for leg erysipelas in sub-Saharan Africa.

    The cans of fuel cartridges used in reactors of the gas-graphite type have either longitudinal fins of variable thickness, short herring-bone fins, or else a mixture of the two. An important test of the strength of these cartridges is their behaviour during thermal cycling carried out in cells reproducing in-pile conditions. It has been observed during with rapid cooling that there occurs a shortening at the base of the fins which can be accompanied in particular by a compression effect at the fin type, which has a tendency to curl, and by a tractive force acting on the body of the can at the ends of the longitudinal fins; this last phenomenon can result in a fracturing of the welds at the extremities or of the ends of the cartridge. This report presents first of all the way in which the stress diagram can be drawn for a can touching the fuel, and then the effect of the ratchet along a fin fixed to a bar with or without grooves. Finally the importance is shown of the test cycling variables (temperature, heating and cooling rates). (authors) [French] Les gaines des cartouches combustibles des reacteurs de la filiere graphite-gaz comportent soit des ailettes longitudinales plus ou moins epaisses, soit de courtes ailettes a chevrons, soit un ensemble des deux. Un test important de la tenue des cartouches, est la tenue au cyclage thermique en cellule pour reproduire le comportement en pile. On a observe au cours des cyclages a refroidissement rapide, un raccourcissement a la base des ailettes qui peut s'accompagner notamment d'une mise en compression du sommet de l'ailette qui a tendance a friser, et d'une traction exercee sur le corps des gaines au bout des ailettes longitudinales; ce dernier phenomene peut se traduire par des ruptures de soudures d'extremites ou des parties terminales de la cartouche. Ce rapport presente d'abord la maniere dont peut etre trace le diagramme des contraintes dans une gaine liee au combustible, puis l'effet du rochet le long d

    parametres en milieu fini sont exprimes en fonction des parametres correspondants en milieu infini par l'intermediaire du laplacien et des aires de migration anisotropes, et d'autre part que tous ces parametres sont exprimes en fonction des integrales sur une seule cellule et non sur toute la pile. Une etude preliminaire moins detaillee est d'abord faite pour bien distinguer entre ce qu'on appelle 'parametres dynamiques' et 'parametres statiques' et pour preciser le sens que l'on donne aux deux termes dans ce rapport. On donne en annexe des traitements approximatifs a un groupe pour l'etude de la structure fine dynamique, de la constante de temps en milieu infini, et des coefficients de diffusion anisotrope dans des reseaux non-multiplicateurs.

    2016-12-01

    Full Text Available The aim of this paper is to show boundaries between fair and harmful tax competition. The author analyses OECD’s reports and literature related to the tax competition. In the beginning, the author presents the notion of tax competition and its division into fair and unfair tax competition. Differences between tax heaven and preferential tax regime are also discussed. In the summary, the author highlights that boundaries between fair and harmful tax competition are not obvious, but there are well-known guidelines, which let distinguish above-mentioned issues. The author considers that there are real tax burden, effective exchange of tax information and transparency in the fair tax regime. The author states that taxpayer can do justified tax planning in such tax system.

    The 'Nuclex 75' - fourth international technical fair and specialist meetings for the nuclear industry - takes place from the 7th to the 11th October 1975 in the halls of the Schweizer Mustermesse in Basel. The meeting, which has taken place at three-yearly intervals since 1966, is divided into a technical fair and a congress. 422 exhibitors from 25 countries take part in the 'Nuclex 75'. Several industrial countries are again represented by communal exhibitions. The editorial office of 'Atom and Electricity' gives a few hints on the technical fair to follow which are based on the papers of the exhibitor sent in up to the editor's closing date. A detailed report on the technical fair as well as on important topics of the congress will appear in volume 11/12 1975. (orig./LH) [de

    Nilsson, Pål

    2006-01-01

    In communication networks, fair sharing of resources is an important issue for one main reason. The growth of network capacity is in general not matching the rapid growth of traffic. Consequently, the resources consumed by each user have to be limited. This implies that users cannot always be assigned the end-to-end bandwidth they ask for. Instead, the limited network resources should be distributed to users in a way that assures fair end-to-end bandwidth assignment among them. Obtaini...

    Full Text Available Cet article propose une lecture anthropologique de la manière dont les habitants des grands ensembles de périphéries urbaines délimitent, administrent, transforment matériellement et symboliquement les espaces et les lieux de leur quotidien pour faire territoire. Nous nous intéresserons à la fabrication de ces entités spatiales dont chaque individu se donne la liberté de disposer chaque jour selon un usage singulier et qu’il entoure d’un champ symbolique spécifique, garant d’identité. Ces « fabrications sociospatiales » seront abordées à partir d’une recherche empirique menée auprès d’habitants de deux terrains d’enquêtes situés dans des périphéries de villes moyennes.This paper proposes an anthropological reading of how the inhabitants of large urban peripheries define, administer, and process their daily spaces and places from a material as much as symbolical point of view to give sense to their territory. We will focus on the making of these spatial entities, witch everyone can dispose of everyday individually, to guarantee their identity. These “socio spatial creations” will be based on an empirical research, that is to say surveys conducted among the suburbians of two towns.

  11. Problèmes entomologiques en replantation des palmeraies et des cocoteraies

    Mariau Dominique

    2000-03-01

    Full Text Available C’est aux alentours de la vingt-cinquième année que l’on envisage de replanter une palmeraie. C’est en effet vers cet âge que commencent à se poser des problèmes de récolte en raison de la taille des palmiers. En un quart de siècle, l’amélioration génétique aura suffisamment fait de progrès pour escompter un gain de production de l’ordre de 20%. Enfin, dans certaines situations, plusieurs maladies ont pu affecter les vieilles palmeraies. Avec de 15 à 25% d’arbres manquants, principalement lorsque ceux-ci se présentent sous la forme de taches, une diminution de la production se fait nettement sentir. Cela peut, par exemple, être le cas avec les maladies de la fusariose en Afrique de l’Ouest, lorsque la palmeraie n’a pas été plantée avec du matériel végétal tolérant, ou du ganoderma en Malaisie. Le renouvellement des cocoteraies se fait avec un espace de temps beaucoup plus long. En effet, la récolte des noix peut se faire au sol et la hauteur des cocotiers n’est donc pas un facteur limitant. Par ailleurs, la majorité des cocoteraies étant sous la forme de petites plantations villageoises, les agriculteurs rechignent toujours à abattre leurs cocotiers, même si des semences potentiellement plus productives leurs sont proposées. Ce sont les raisons pour lesquelles les cocoteraies de 50 ans et plus représentent la règle. L’abattage d’une plantation de palmiers à huile ou de cocotiers constitue naturellement un changement brutal de l’environnement, ce qui a des conséquences importantes notamment sur l’entomofaune, parmi laquelle des ravageurs majeurs ainsi que leurs ennemis naturels.

  15. Etude theorique et experimentale des evaporateurs de dioxyde de carbone operant dans des conditions de givrage

    Bendaoud, Adlane Larbi

    Les evaporateurs de refrigeration sont surtout du type tube a ailettes, appeles serpentins, et fonctionnent dans l'une des conditions suivantes: seche, humide ou avec formation de givre. Il a ete demontre que la formation du givre sur la paroi exterieure de l'echangeur engendre une surconsommation energetique a cause des operations de degivrage puisque 15 a 20% seulement de la chaleur produite sert au degivrage tandis que le reste est dissipee dans l'environnement [1]. Avec l'avenement des nouveaux refrigerants, moins nocifs envers l'environnement, l'industrie du froid se trouve penalisee du fait que peu ou pas de composantes mecaniques (compresseur, pompe, echangeur...etc.) adaptees sont disponibles [3]. Il s'agit pour la communaute des frigoristes de combler ce retard technologique en redeveloppant ces composantes mecaniques afin qu'elles soient adaptees aux nouveaux refrigerants. Dans cette optique, et afin de mieux comprendre le comportement thermique des evaporateurs au CO2 fonctionnant dans des conditions seches, qu'un groupe de chercheurs du CanmetENERGIE avaient lance, en 2000, un programme de R & D. Dans le cadre de programme un outil de simulation des evaporateurs au CO2 a ete developpe et un banc d'essai contenant une boucle secondaire de refrigeration utilisant le CO2 comme refrigerant a ete construit. Comme continuite de ce travail de recherche, en 2006 ce meme groupe de recherche a lance un nouveau projet qui consiste a faire une etude theorique et experimentale des evaporateurs au CO2 operants dans des conditions de givrage. Et, c'est exactement dans le cadre de ce projet que se positionne ce travail de these. Ce travail de recherche a ete entrepris pour mieux comprendre le comportement thermique et hydrodynamique des serpentins fonctionnant dans des conditions de givrage, l'effet des circuits de refrigerant ainsi que celui des parametres geometriques et d'operation. Pour cela, un travail theorique supporte par une etude experimentale a ete effectue

    Bouleau, Maurice

    1961-01-17

    In order to study the transformation kinetics of U-Zr alloys with a Zr content of 6 per cent in weight, the authors searched for a slow enough electrolytic polishing bath, and for an attack and examination method to highlight martensite structures produced by austempering and water tempering, and ultra-fine decomposition structures obtained by austempering. The authors explain the choice of a perchloric-butyl glycol polishing bath, of an examination under polarized light or normal light after appropriate attacks. These studies are reported for annealed alloys, and for processed alloys with martensite or ultra-fine decomposition structures [French] L'etude de la cinetique de transformation des alliages U-Zr a 6 pc en poids de Zr a necessite la recherche d'un bain de polissage electrolytique assez lent et de methodes d'attaque et d'examen qui permettent la mise en evidence des structures martensitiques (provenant de trempes etagees ou de trempes a l'eau) et des structures de decomposition ultrafines (obtenues par trempes etagees). Nous nous sommes arretes dans notre choix: - sur un bain de polissage perchlorique-butyl glycol; sur des examens en lumiere polarisee ou en lumiere normale apres attaques appropriees (en cellule dans le meme electrolyte ou au tampon dans un bain phosphorique ethylene glycol).

    In classical radiotherapy, the characteristics of photons interactions undergo limits for the treatment of radioresistant and not well located tumours. Pioneering treatments of patients at the Lawrence Laboratory at Berkeley has demonstrated two advantages of hadrons beams: the Relative Biologic Effect (the RBE) and the ballistic of the beams. Since 1994, the clinical centre at Chiba, has demonstrated successfully the applicability of the method. A physics group, managed by G. Kraft, at Darmstadt in Germany, has underlined the advantages of carbon beams. An European pool, called ENGIGHT (European Network for LIGHt ion Therapy) has been created in which the French ETOILE project appeared. The purpose of the thesis concerns measurements and models of 'in vitro' human cells survival. In the first part, the nowadays situation in particles interactions, tracks and cells structures and radiobiology is presented here. The second is devoted to the models based on the beam tracks and localization of the physical dose. Discussion of sensitivity to various parameters of the model has been realized with the help of numerical simulations. Finally the predictions of the improved model has been compared to experimental irradiations of human cells with argon and carbon beams of the GANIL machine. Conclusion of such study shows the performance and limits of a local model for predicting the radiobiological efficiency of light ions in hadron-therapy. (author)

    2016-01-01

    En 50 ans d'indépendance, le sport camerounais a beaucoup évolué. De 11 en 1970, les fédérations sportives sont passées à plus de 40 aujourd'hui et les titres, trophées et médailles ne se comptent plus depuis lors. Le Cameroun est devenu progressivement une nation où le sport compte et où l'exploit sportif n'est plus méprisé, rejeté, voire vilipendé. Hier assimilés à des brutes épaisses, les sportifs sont aujourd'hui admirés et adulés. Finie l'image négative de marginaux qui leur collait au corps : finis les sous-entendus ridicules où ils étaient classés au bas de l'échelle sociale, juste bons pour bander les muscles et réaliser des performances. C'est cela la plus grande victoire du sport camerounais en 50 ans d'existence. Il a réussi à faire l'unanimité et les performances des sportifs devenues pour toute la nation un modèle, une référence et un réel motif de fierté.

    2011-01-01

    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.

  6. Formation des formateurs en ligne : obstacles, rôles et compétences

    Louise Sauvé

    2004-01-01

    Full Text Available L’adoption d’une technologie de l’information et de la communication (TIC pour la formation ne peut se faire sans changement dans l’organisation. Ces changements touchent les formateurs, hommes et femmes, qui ont une histoire professionnelle, une mentalité, des pratiques qui se sont construites au cours des années et dans un contexte précis de travail. Or les changements technologiques peuvent déstabiliser la vie professionnelle des formateurs. Il est donc essentiel de gérer ce changement, car le succès des projets d’introduction des TIC dans la formation n’est plus fonction de la puissance des technologies, mais plutôt de la capacité des formateurs à exploiter leur potentiel afin de changer et d’améliorer l’efficience du processus d’apprentissage. C’est dans un contexte d’implantation d’une formation des formateurs en ligne que se situe cet article qui aborde les questions suivantes : quels sont les obstacles au changement par rapport à l’adoption des TIC dans le milieu de la formation? Quels sont les principaux rôles d’un formateur en ligne (ou e-formateur? Quelles sont les compétences générales que les formateurs doivent développer pour soutenir les apprenants dans un contexte de formation en ligne (synchrone et asynchrone?

  7. L'implication des langues dans l'élaboration et la publication des recherches scientifiques l'exemple du français parmi d'autres langues

    Blanchet, Philippe

    2015-01-01

    Pour certains, les langues sont des outils neutres sans liens (qu'ils soient nécessaires ou accidentels et historiques) avec des univers culturels, sans liens avec des façons de penser. Pour ceux-là, en tout cas, elles peuvent n'être que des outils quand on tient des discours scientifiques, ce qui implique une conception de la science comme étant neutre, objective, détachée du monde social. Dans cette vision, on peut sans encombre, y compris en sciences humaines, choisir n'importe quelle(s) langue(s) pour le faire. L'objectif de ce volume est de proposer une autre vision des rapports profonds

    2010-10-01

    1. This study was conducted to verify the impact of different kinds of material and the number of times of litter reuse on the incidence of chicken pathologies. Approximately 4·5 million broilers from conventional Brazilian farms were evaluated in the abattoir for cellulitis, arthritis and contact foot-pad dermatitis. 2. Four different kinds of litter material, Brachiaria grass, corncob, sawdust and rice shell, were used. Brachiaria grass litter showed the highest incidence of contact foot-pad dermatitis. Corncob litter also showed some negative effects on foot quality. Broilers raised on rice shell litter showed good results in terms of the incidence of contact foot-pad dermatitis. The best results were obtained with sawdust litter, because the incidence of cellulitis and arthritis were the lowest and the incidence of contact foot-pad dermatitis was also very low.

    Boris Sharkov

    2010-01-01

    Complete text of publication follows. 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 fore-front 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 hadron, nuclear, atomic 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 matter on both a microscopic and on a cosmic scale. This presentation outlines the current status of the Facility for Antiproton and Ion Research. It is expected that the actual construction of the facility will commence in 2010 as the project has raised more than one billion euro in funding. The sequence and scope of the construction will be described. Also the physics program of FAIR, based on the acquired funding, will be presented.

  11. Adaptive Filtering Queueing for Improving Fairness

    Jui-Pin Yang

    2015-06-01

    Full Text Available In this paper, we propose a scalable and efficient Active Queue Management (AQM scheme to provide fair bandwidth sharing when traffic is congested dubbed Adaptive Filtering Queueing (AFQ. First, AFQ identifies the filtering level of an arriving packet by comparing it with a flow label selected at random from the first level to an estimated level in the filtering level table. Based on the accepted traffic estimation and the previous fair filtering level, AFQ updates the fair filtering level. Next, AFQ uses a simple packet-dropping algorithm to determine whether arriving packets are accepted or discarded. To enhance AFQ’s feasibility in high-speed networks, we propose a two-layer mapping mechanism to effectively simplify the packet comparison operations. Simulation results demonstrate that AFQ achieves optimal fairness when compared with Rotating Preference Queues (RPQ, Core-Stateless Fair Queueing (CSFQ, CHOose and Keep for responsive flows, CHOose and Kill for unresponsive flows (CHOKe and First-In First-Out (FIFO schemes under a variety of traffic conditions.

  13. Partner choice creates fairness in humans.

    Debove, Stéphane; André, Jean-Baptiste; Baumard, Nicolas

    2015-06-07

    Many studies demonstrate that partner choice has played an important role in the evolution of human cooperation, but little work has tested its impact on the evolution of human fairness. In experiments involving divisions of money, people become either over-generous or over-selfish when they are in competition to be chosen as cooperative partners. Hence, it is difficult to see how partner choice could result in the evolution of fair, equal divisions. Here, we show that this puzzle can be solved if we consider the outside options on which partner choice operates. We conduct a behavioural experiment, run agent-based simulations and analyse a game-theoretic model to understand how outside options affect partner choice and fairness. All support the conclusion that partner choice leads to fairness only when individuals have equal outside options. We discuss how this condition has been met in our evolutionary history, and the implications of these findings for our understanding of other aspects of fairness less specific than preferences for equal divisions of resources. © 2015 The Author(s) Published by the Royal Society.

The BTR provides the technical description, cost, schedule, and assessments of risk for the proposed new facility. The purpose of the BTR is to provide a reliable basis for the construction, commissioning and operation of FAIR. The BTR is one of the central documents requested by the FAIR International Steering Committee (ISC) and its working groups, in order to prepare the legal process and the decisions on the construction and operation of FAIR in an international framework. It provides the technical basis for legal contracts on contributions to be made by, so far, 13 countries within the international FAIR Consortium. The BTR begins with this extended Executive Summary as Volume 1, which is also intended for use as a stand-alone document. The Executive Summary provides brief summaries of the accelerator facilities, the scientific programs and experimental stations, civil construction and safety, and of the workproject structure, costs and schedule.

  15. Are two penicillins better than one? A systematic review of oral flucloxacillin and penicillin V versus oral flucloxacillin alone for the emergency department treatment of cellulitis.

    Quirke, Michael; O'Sullivan, Ronan; McCabe, Aileen; Ahmed, Jameel; Wakai, Abel

    2014-06-01

    Flucloxacillin either alone or combined with penicillin V is still the first-line antibiotic drug of choice for the treatment of cellulitis in emergency departments (EDs) in Ireland. The rationale for this antibiotic regimen is their anti-staphylococcal and anti-streptococcal activity. To determine the clinical efficacy, tolerability and safety of oral flucloxacillin alone (monotherapy) compared with a combination of flucloxacillin with penicillin V (dual therapy) in the ED-directed outpatient treatment of cellulitis. We searched the following electronic databases: MEDLINE (1950 to August 2011), EMBASE (1980 to August 2011), Cochrane Central Register of Controlled Clinical Trials (CENTRAL) (The Cochrane Library 2011, Issue), OpenGrey, Current Controlled Trials metaRegister of Clinical Trials (August 2011) and reference lists and websites of potential trials. We performed cross-referencing from the reference lists of major articles on the subject. We imposed no language restriction. Despite a comprehensive literature search to identify relevant studies, no randomized-controlled trials that fulfilled the inclusion criteria were found. Despite its common use, there are no published randomized-controlled trials comparing flucloxacillin monotherapy with a combination of flucloxacillin and penicillin V in the ED management of cellulitis. We discuss existing European and North American prescribing rationale and current guidelines.

  16. Photonique des Morphos

    Berthier, Serge

    2010-01-01

    La photonique est déjà présente dans notre vie quotidienne, et on attend maintenant que la manipulation des photons permette aussi le traitement logique des informations. Cependant, l’élément de base qui permet cette manipulation de la lumière, le cristal photonique, est d’une réalisation complexe et mal contrôlée. Dans la course à la maîtrise de la lumière, les structures photoniques naturelles ont beaucoup à nous apprendre. C’est ce que nous montre Serge Berthier qui étudie dans ce livre la structure des écailles des Morphos. Tenant compte de l’essor récent des approches biomimétiques, il présente de manière détaillée plus de dix-huit techniques expérimentales utilisées pour ses analyses, ainsi que les diverses approches théoriques développées pour la modélisation de structures multi-échelles complexes. Première étude quasi-exhaustive des structures fines d’un genre et des propriétés optiques ainsi que colorimétriques générées, ce livre fournit aux entomologiste...

    Cet ouvrage collectif offre aux enseignants et chercheurs en droit international, aux praticiens et aux étudiants, une analyse actualisée du droit des organisations internationales. Il dresse en cinq parties un tableau, illustré par des exemples variés, des problématiques que soulève le phénomène polymorphe d institutionnalisation de la société internationale. La première partie est consacrée au phénomène des « organisations internationales », sous l angle à la fois de l institutionnalisation progressive des relations internationales et de la difficulté à cerner une catégorie unifiée. La deuxième partie rend compte de la création, de la disparition et des mutations des organisations internationales, ici envisagées comme systèmes institutionnels et ordres juridiques dérivés. La troisième partie analyse l autonomie que l acquisition de la personnalité juridique et de privilèges et immunités, un organe administratif intégré, un personnel ou un budget propres confèrent aux organi...

  8. Silencage du gene MDR1 et resensibilisation des cellules MCF-7 MDR a la doxorubicine en utilisant les nanoparticules chitosane/MDR1-siARN

    El-Ariss, Mohamad

    Cancer is the leading cause of death in Canada and is responsible for about 30% of all deaths in the country.[1] It is estimated that by 2015, one in four Canadians (24% women and 29% men) will die from cancer. In the world and only for 2012, 14 million new cancer cases and 8.2 million deaths from the disease were reported.[2] The worst is yet to come because, according to World Health Organization, the number of new cases is expected to increase by about 70% over the next two decades. The high mortality associated with cancer is partly explained by the acquisition of drug resistance that make patients refractory to chemotherapy. In fact, cancer cells exposed to a cytotoxic agent during chemotherapy, may develop a resistance to this agent as well as various agents sharing structural or functional similarities. These cancer cells are known for multidrug resistance ("Multiple Drug resistant cells"). The development of resistance to chimiodrogues is a major public health problem that presents an obstacle for the development of new cancer treatments. MCF-7 MDR are established cell lines of human breast cancer that have developed resistance to chimiodrogues such as doxorubicin. MCF-7 MDR have the particularity to over-express P-gp protein that is responsible for the detoxification of cells by reflux of chimiodrogues. The purpose of this study was therefore to reduce the expression of P-gp, encoded by the MDR1 gene (also called gene ABCB1) in cancer cells MCF-7, and re-sensitize MCF-7 MDR cells to anti-cancer treatments. In order to modify MDR1 gene expression, we used small RNAi called siRNA that are specific to the MDR1 gene. In total, 4 duplexes of siRNA have been used: siRNA_1, siRNA_1M, siRNA_2 and siRNA_2M. Each of the duplexes strands is consists of 21 nucleic acids and has two protruding nucleic acids (overhangs) at the 3' end. siRNA_1 and siRNA_1M are complementary to the nucleic acid sequence (577-595 nucleic acids ) of the MDR1 gene, whereas siARN_2 and siARN_2M are complementary to a sequence shifted slightly downstream in the same gene (583-607 nucleic acids). RNA duplexes siRNA_1 and siARN_2 consist exclusively of DNA while "modifed" siRNA_1M and si RNA_2M consist of RNA overhangs. siRNA duplexes (siRNA_1 and siRNA_2) were chosen from the work published by Hao Wu et al. (2003), Stege et al. (2004) and Miletti-Gonzalez et al. (2005) which showed that these siRNA sequences are effective to silence MDR1 gene in cancer cells (breast cancer cells MCF-7 / AdrR and MCF-7 / BC-19 and stomach cancer cells: EPG85-257RDB).[3-5] Moreover, Strapps et al. (2010) showed that the use of siRNA having overhangs formed of ribonucleotides leads to a similar silencing but lasting longer in vivo and in vitro compared to the use of siRNA containing deoxyribonucleotides overhangs.[6] Thus siARN_1M and siARN_2M sequences correspond to siARN_1 and siARN_2 sequences but whose overhangs are formed of ribonucleotides. These siRNA specific to the MDR1 gene (MDR1-siRNA) were combined to chitosan to form nanoparticles capable of protecting these MDR1-siRNA and delivering it into the MCF-7 MDR cells. Chitosan used here as a delivery system, is a natural and biodegradable polysaccharide whose biological properties are defined by its average molecular weight (MW) and by its degree of deacetylation (DD). When the positively charged chitosan is added with the negatively charged siRNA, there is formation of nanoparticles by electrostatic attraction. In this project, chitosan 92-10 (DDA- MW) was used as a delivery system with a N:P (ratio chitosan amino groups: RNA phosphate) of 5. Analysis by dynamic light scattering (DLS) demonstrated that the nanoparticles have a diameter between 62.56 and 82.72 nm and a zeta potential ranging from 17.4 to 23.5 mV. Analysis by confocal microscopy showed that chitosan (92-10-5)/labeled siRNA are internalized in MCF-7 MDR cells and that siRNAs are released in the cytoplasm. MCF-7 cells resistant MDR were transfected in vitro with different chitosan nanoparticles 92-10/MDR1-siRNA. qPCR quantification showed that transfection of MCF-7 MDR cells leads to inhibition of the expression of the MDR1 gene by 71%. In addition, induced cytotoxicity tests showed that the use of nanoparticles allows resensitizing cells to doxorubicin. In fact, the mortality rate of MDR MCF-7 cells exposed to doxorubicin increased to 60% after transfecting the cells with the nanoparticles chitosane (92-10-5)/ MDR1-siRNA. In conclusion, we have developed Chitosan (92-10-5)/ MDR1-siRNA nanoparticles that reduce the expression of P-gp in cells and allow the latter to re-sensitize to Doxorubicin. This study demonstrated the potential of chitosan nanoparticles (92-10-5)/ MDR1-siRNA for the treatment of cancers resistant to chemotherapy.

    It has been suggested that human Mesenchymal Stem Cells (hMSC) could be used to repair numerous injured tissues. We have studied the potential use of hMSC in order to limit radiation-induced skin lesions. Immuno-deficient NOD/SCID mice were locally irradiated to the leg (30 Gy, dose rate 2.7 Gy/mn) using a {sup 60} Co source in order to induce a severe skin lesion. Cultured bone marrow hMSC were delivered intravenously to the mice. The irradiated skin samples were studied for the presence of the human cells, the severity of the lesions and the healing process. Macroscopic analysis and histology results showed that the lesions were evolving to a less severe degree of radiation dermatitis following hMSC transplant when compared to irradiated non-transplanted controls. Clinical scores for the studied skin parameters of treated mice were significantly improved. A faster healing was observed when compared to untreated mouse. Immuno-histology and Polymerase Chain reaction (PCR) analysis provided evidence that the human cells were found in the irradiated area. These results suggest a possible use of hMSC for the treatment of the early phase of the cutaneous radiation syndrome. A successful transplant of stem cells and subsequent reduction in radiation-induced complication may open the road to completely new strategies in cutaneous radiation syndrome therapy. (authors)

    In the area of skin injuries caused by ionizing radiations; the recent opportunity give us the the possibility to manage victims of radiation accidents with skin acute symptoms of irradiation. The approach of cell therapy developed for these patients could be in a second time, used for other types of injuries as thermal burns and the injuries linked to overexposure in radiotherapy. In spite of the diversity of approaches of allogeneic and autologous transplantation, the prognosis of deep and extended radioinduced burns is not completely satisfying because of inflammatory recurrences, origin of graft failures. The stem cells have been used in association. The stem cells were got from sampling of autologous bone marrow after an expansion in vitro from 15 to 17 days. The cultures were realised in medium with 8% of platelet lysate (clinical grade). The cells have been given by injection in complement of epidermis auto graft. A spectacular effect was noticed the day after the injection, but disappearing in some days encouraging to realize supplementary injections. An effect of the quickness and the quality of the graft success is appeared significant too. no necrosis recurrence for the patients after four years for the first one of them. We think that the stem cells participate to the local control of inflammation. (N.C.)

    Full Text Available L’alimentation intervient à différents niveaux dans le déroulement de la maladie cancéreuse : au niveau du risque [1] et au niveau de l’évolution en modifiant le risque de survenue des métastases. L’alimentation influence-t-elle aussi la réponse aux traitements anticancéreux ? À l’appui de cette hypothèse viennent deux observations indirectes réalisées dans le cancer du sein : nos données [2, 3] ainsi que les observations épidémiologiques provenant d’autres travaux [4] ont apporté des arguments supportant l’hypothèse que les lipides alimentaires peuvent influencer la réponse des tumeurs mammaires aux traitements. On sait que la composition des lipides membranaires n’est pas génétiquement déterminée, mais qu’elle dépend des acides gras disponibles aux tissus périphériques. Le type d’acides gras disponibles est influencé par les apports alimentaires. Comme les tumeurs incorporent dans leurs lipides les acides gras disponibles de façon similaire aux autres tissus [5], il est plausible que les habitudes alimentaires (apports alimentaires en acides gras polyinsaturés, vitamines anti ou pro-oxydantes puissent influencer leur chimiosensibilité en apportant aux cellules tumorales des substrats de peroxydation.

    Full Text Available Les prisonniers politiques furent très nombreux en Syrie des années 1970 jusqu’à leur libération progressive de 1991 à 2005. Si leur conditions de vie en prison, les interrogatoires et la torture sont parfois abordés par les ex-prisonniers, leur existence après la prison ne semble susciter aucun intérêt. Cet article se propose de commencer à combler cette lacune, en analysant les facteurs qui pèsent sur la vie post-carcérale. Les conditions et la durée d’incarcération, le milieu social et affectif trouvé à la sortie, les réseaux de relation, la chance de trouver un travail et des moyens de subsistance sont autant d’éléments qui créent des conditions plus ou moins favorables à la réinsertion. Les ex-prisonniers politiques rencontrent quoi qu’il en soit d’énormes difficultés, y compris à gérer leur propre image. Des initiatives commencent à se faire jour pour tenter d’obtenir la réhabilitation et des dédommagements pour ces individus injustement brisés.

  4. Fair process: managing in the knowledge economy.

    Kim, W C; Mauborgne, R

    1997-01-01

    Unlike the traditional factors of production--land, labor, and capital--knowledge is a resource that can't be forced out of people. But creating and sharing knowledge is essential to fostering innovation, the key challenge of the knowledge-based economy. To create a climate in which employees volunteer their creativity and expertise, managers need to look beyond the traditional tools at their disposal. They need to build trust. The authors have studied the links between trust, idea sharing, and corporate performance for more than a decade. They have explored the question of why managers of local subsidiaries so often fail to share information with executives at headquarters. They have studied the dynamics of idea sharing in product development teams, joint ventures, supplier partnerships, and corporate transformations. They offer an explanation for why people resist change even when it would benefit them directly. In every case, the decisive factor was what the authors call fair process--fairness in the way a company makes and executes decisions. The elements of fair process are simple: Engage people's input in decisions that directly affect them. Explain why decisions are made the way they are. Make clear what will be expected of employees after the changes are made. Fair process may sound like a soft issue, but it is crucial to building trust and unlocking ideas. Without it, people are apt to withhold their full cooperation and their creativity. The results are costly: ideas that never see daylight and initiatives that are never seized.

These hypotheses are tested on the basis of an analysis of the statutory provisions, the pronouncements of accounting and other regulatory bodies and accounting norms and theories. After setting forth the research objectives and the hypotheses, the necessity of the FVA is reviewed and the underlying philosophy is analyzed. Impediments in performing audits of fair-value-based measurements are then identified and the US auditing standards and their international counterparts are touched upon. Finally, some safeguards and precautions for the auditor in an audit of fair-value measurements are presented.

  13. Fair and optimistic quantum contract signing

    Paunković, N.; Bouda, J.; Mateus, P.

    2011-12-01

    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-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.

  7. THE (UN? FAIRNESS OF FAIR VALUE: SFAS 157, IRVING FISHER AND GECON

    Paulo Roberto Barbosa Lustosa

    2017-01-01

    Full Text Available Objective: The objective of this study is to assess the level of adherence of explicit and implicit measurement concepts present in SFAS 157 – Fair Value Measurements to traditional economic-accounting concepts. Background: The expansion of situations in which fair value measurement is required makes more difficult to ensure that the computed measure of value is actually fair. Out of the objectivity of current sales prices in an active market, all other measures of value are expectations about the future, inherently uncertain and inaccurate. Thus, the desired justice of the computed figures lies not in its accuracy, but in the using of the correct concepts for measuring accounting transactions and events. Method: To reach the objective, the characteristics of this standard are confronted with the secular concept of capital and income set by the laureate American neoclassical economist Irving Fisher, which were incorporated into Information System for Economic Management (Gecon. Results: The results indicate that SFAS 157 fair value concept and measurement structure are incorrect or incomplete, suggesting that the maintenance of the fair value expression in accounting seems inadequate. Contributions: This paper contributes to the literature on accounting measurement showing that as a measurement concept in accounting fair value seems inadequate. In abnormal situations or absence of a market, the measure found is always inexact and subjective, and therefore is not correct to call fair the quantity resulting from this arbitrary calculation.

  8. What is a fair CO2 tax increase? On fair emission reductions in the transport sector

    Hammar, Henrik; Jagers, Sverker C.

    2007-01-01

    We examine how individual preferences for fair reductions of carbon dioxide (CO 2 ) emissions affect the support for increases in the CO 2 tax on gasoline and diesel. We assume that people not only care about their own material welfare, but also have preferences for fairness in policy design, and we explore the implications using original data from a mail questionnaire sent to a representative sample of the Swedish population. The main result is that fairness in policy design does matter. Those respondents who adhere to a fairness principle tend to be relatively more positive to increases in the CO 2 tax. One possible explanation for this result is that there is a relatively high degree of reciprocity regarding the origin of emissions and the fairness regarding who should bear the burden of CO 2 reductions. Via a split sample analysis, we also find that the relative importance of fairness principles is dependent upon whether one uses a car often or not. This sheds light on the potential goal conflict between the importance of fairness principles and self-interest in the form of a need for private car transportation. (author)

  12. High burnup models in computer code fair

    Dutta, B K; Swami Prasad, P; Kushwaha, H S; Mahajan, S C; Kakodar, A [Bhabha Atomic Research Centre, Bombay (India)

    1997-08-01

    An advanced fuel analysis code FAIR has been developed for analyzing the behavior of fuel rods of water cooled reactors under severe power transients and high burnups. The code is capable of analyzing fuel pins of both collapsible clad, as in PHWR and free standing clad as in LWR. The main emphasis in the development of this code is on evaluating the fuel performance at extended burnups and modelling of the fuel rods for advanced fuel cycles. For this purpose, a number of suitable models have been incorporated in FAIR. For modelling the fission gas release, three different models are implemented, namely Physically based mechanistic model, the standard ANS 5.4 model and the Halden model. Similarly the pellet thermal conductivity can be modelled by the MATPRO equation, the SIMFUEL relation or the Halden equation. The flux distribution across the pellet is modelled by using the model RADAR. For modelling pellet clad interaction (PCMI)/ stress corrosion cracking (SCC) induced failure of sheath, necessary routines are provided in FAIR. The validation of the code FAIR is based on the analysis of fuel rods of EPRI project ``Light water reactor fuel rod modelling code evaluation`` and also the analytical simulation of threshold power ramp criteria of fuel rods of pressurized heavy water reactors. In the present work, a study is carried out by analysing three CRP-FUMEX rods to show the effect of various combinations of fission gas release models and pellet conductivity models, on the fuel analysis parameters. The satisfactory performance of FAIR may be concluded through these case studies. (author). 12 refs, 5 figs.

  14. De l'importance des orbites periodiques: Detection et applications

    Doyon, Bernard

    L'ensemble des Orbites Periodiques Instables (OPIs) d'un systeme chaotique est intimement relie a ses proprietes dynamiques. A partir de l'ensemble (en principe infini) d'OPIs cachees dans l'espace des phases, on peut obtenir des quantites dynamiques importantes telles les exposants de Lyapunov, la mesure invariante, l'entropie topologique et la dimension fractale. En chaos quantique (i.e. l'etude de systemes quantiques qui ont un equivalent chaotique dans la limite classique), ces memes OPIs permettent de faire le pont entre le comportement classique et quantique de systemes non-integrables. La localisation de ces cycles fondamentaux est un probleme complexe. Cette these aborde dans un premier temps le probleme de la detection des OPIs dans les systemes chaotiques. Une etude comparative de deux algorithmes recents est presentee. Nous approfondissons ces deux methodes afin de les utiliser sur differents systemes dont des flots continus dissipatifs et conservatifs. Une analyse du taux de convergence des algorithmes est aussi realisee afin de degager les forces et les limites de ces schemes numeriques. Les methodes de detection que nous utilisons reposent sur une transformation particuliere de la dynamique initiale. Cette astuce nous a inspire une methode alternative pour cibler et stabiliser une orbite periodique quelconque dans un systeme chaotique. Le ciblage est en general combine aux methodes de controle pour stabiliser rapidement un cycle donne. En general, il faut connaitre la position et la stabilite du cycle en question. La nouvelle methode de ciblage que nous presentons ne demande pas de connaitre a priori la position et la stabilite des orbites periodiques. Elle pourrait etre un outil complementaire aux methodes de ciblage et de controle actuelles.

    1961-07-01

    The author reviews precisely the analogical techniques used for the resolution of the kinetic equations of nuclear reactors. Prior to this, he recalls the reasons which oblige physicians and engineers, even today, to use electronic machines in this domain. The author then considers the technological problems posed by the range of values which the various nuclear parameters adopt. In each case, he shows that a compromise is possible allowing an optimum precision. He compares the results to those obtained by arithmetic calculation and uses the examples chosen in a critical analysis of the present possibilities of the two methods of calculation. (author) [French] L'auteur cherche a faire un point aussi exact que possible des techniques analogiques utilisees pour resoudre les equations cinetiques des reacteurs nucleaires. Il rappelle auparavant les raisons pour lesquelles physiciens et ingenieurs sont obliges, encore aujourd'hui, de faire appel aux machines electroniques dans ce domaine. Puis il etudie les problemes technologiques que souleve le champ des valeurs prises par les differents parametres nucleaires. Dans chacun des cas, il montre l'existence d'un compromis qui permet d'atteindre une precision optimum. Il compare les resultats obtenus a ceux provenant de calculateurs arithmetiques et profite des exemples choisis pour faire une analyse critique des possibilites actuelles offertes par les deux modes de calcul.

We propose...... that this disagreement can largely be resolved in light of an extended Social Heuristics Hypothesis. Divergent findings may be attributed to the interpretation of behavioral effects of ego depletion or neurostimulation, reverse inference from brain activity to the underlying psychological process, and insensitivity...

    Dans le cadre des acquisitions des transformateurs rapides des deux LINACS, de la ligne d'injection PSB et de la machine LEIR, un nouveau hardware a été mis en opération [1]. Celui-ci assure la digitalisation des signaux analogiques et aussi de certains signaux de timing devant cadrer la mesure. Pour ce faire des ADC SIS3300 (SIS3320) et des DPRAM 80408 sont mis en service. Ces unités nécéssitent pour leur fonctionnement des horloges et des timings qui normalement sont intégralement fournis par l'équipement standard CO, notamment des CTRV et autres TG8. Suite à des problèmes d'approvisionnement, il existe des cas où l'on ne dispose pas (du moins pour le court terme) de suffisemment de ressources standard pour pourvoir au timing mentionné plus haut. Le tiroir qui fait l'objet de la présente description assure, avec certaines limitations, la génération des timings et autres horloges utilisées par les DPRAM 80408 et les ADC SIS3300.

  2. Hypothesis of Lithocoding: Origin of the Genetic Code as a "Double Jigsaw Puzzle" of Nucleobase-Containing Molecules and Amino Acids Assembled by Sequential Filling of Apatite Mineral Cellules.

    Skoblikow, Nikolai E; Zimin, Andrei A

    2016-05-01

    The hypothesis of direct coding, assuming the direct contact of pairs of coding molecules with amino acid side chains in hollow unit cells (cellules) of a regular crystal-structure mineral is proposed. The coding nucleobase-containing molecules in each cellule (named "lithocodon") partially shield each other; the remaining free space determines the stereochemical character of the filling side chain. Apatite-group minerals are considered as the most preferable for this type of coding (named "lithocoding"). A scheme of the cellule with certain stereometric parameters, providing for the isomeric selection of contacting molecules is proposed. We modelled the filling of cellules with molecules involved in direct coding, with the possibility of coding by their single combination for a group of stereochemically similar amino acids. The regular ordered arrangement of cellules enables the polymerization of amino acids and nucleobase-containing molecules in the same direction (named "lithotranslation") preventing the shift of coding. A table of the presumed "LithoCode" (possible and optimal lithocodon assignments for abiogenically synthesized α-amino acids involved in lithocoding and lithotranslation) is proposed. The magmatic nature of the mineral, abiogenic synthesis of organic molecules and polymerization events are considered within the framework of the proposed "volcanic scenario".

    2013-01-01

    Résumé Objectif Faire le résumé des anciens et des nouveaux moyens de traitement des verrues génitales ou condylomes et déterminer comment les utiliser de manière appropriée. Sources des données Une recherche documentaire a été effectuée dans les bases de données suivantes: MEDLINE, PubMed, EMBASE, base de données des synthèses systématiques et registre central des études contrôlées de la Collaboration Cochrane (en anglais), ACP Journal Club et Trip. Les bibliographies des articles extraits ont aussi été examinées. Les études cliniques, les articles de révision qualitative, les rapports consensuels et les guides de pratique clinique ont été retenus. Message principal Les verrues symptomatiques sont présentes chez au moins 1 % des personnes âgées entre 15 et 49 ans et on estime que jusqu’à 50 % des gens sont infectés par le virus du papillome humain à un moment donné de leur vie. L’imiquimod et la podophyllotoxine sont 2 nouveaux traitements pour les verrues génitales externes qui sont moins douloureux et peuvent être appliqués par les patients à la maison. De plus, il a été démontré que le vaccin quadrivalent contre le virus du papillome humain est efficace pour prévenir les condylomes et le cancer du col. Les plus anciennes méthodes thérapeutiques ont aussi leur place dans certaines situations, comme les verrues intravaginales, urétrales, anales ou récalcitrantes ou encore pour les patientes enceintes. Conclusion Les nouveaux traitements des verrues génitales externes peuvent réduire la douleur causée par la thérapie et le nombre de visites au cabinet. Les autres méthodes thérapeutiques demeurent utiles dans certaines situations.

  5. Social Accounting and Unethical Behavior: Does Looking Fair Undermine Actually Being Fair?

    Hong, Michelle Chiawei

    2016-01-01

    In organizations, it is inevitable that some business activities might seem unfair to subordinates. Social accounts—the explanations managers give their subordinates for those decisions—are known to be a useful tool for managing subordinates’ fairness concerns. Over three decades of research, we learn that social accounts are effectiveness in improving subordinates’ fairness perceptions and reducing their negative reactions. Yet, we have only limited understanding about how social accounts...

  6. Fair processes and fair outcomes: involving local stakeholders in RWM decisions

    Vari, A.

    2004-01-01

    There is a general agreement on the requirements to be met by radioactive waste management strategies. One of the requirements is that both the outcomes of any decisions and the decision-making processes must be seen to be fair. However, there exist multiple legitimate views on fairness and there is no meta-theory that could help decide which of the competing views should be considered valid in a concrete case. Referring to the plurality of views on fairness, Linnerooth-Bayer (forthcoming) argues that the impasse in facility siting processes can be attributed to the failure to take adequate account of the diverse views held by the various stakeholders on fair processes and outcomes. Three fundamental ethical principles have been derived from three basic ethical theories: well-being which is the central concept of utilitarian ethics, justice which is a key notion in egalitarian ethics, and dignity which is central to deontology (Bay and Oughton, 2003). According to utilitarian ethics fairness means that public welfare is maximized even at the cost of stakeholders' individual rights. Costs and benefits can be legitimately distributed in any way; only their overall balance has to be enhanced. In contrary, egalitarian ethics aims for a fair distribution of benefits and costs among stakeholders, while deontology acknowledges universal values of actions, e.g. the respect for individual rights, apart from their consequences. According to the latter ethics, fairness means that stakeholders themselves have the opportunity to learn about the benefits and costs of various options, and having considered them, decide on their position to accept them. How do diverse views on fair decisions materialize in RWM debates? (author)

  8. La fabrique des sciences des institutions aux pratiques

    Benninghoff, Martin; Crettaz von Roten, Fabienne; Merz, Martina

    2006-01-01

    Aujourd'hui, les façons de produire, d'organiser, d'évaluer et d'utiliser les savoirs sont en profond débat. De plus en plus, l'Etat, la société civile et l'économie tentent d'influencer les activités des universités et des laboratoires de recherche. Ces développements mettent à l'épreuve tout à la fois les fondements des systèmes d'enseignement supérieur et de recherche, l'autonomie des institutions scientifiques, la définition des frontières des savoirs et l'acceptation des sciences. Dans des contextes suisses et européens, cet ouvrage s'intéresse aux manières dont les sciences et les technologies sont fabriquées, en analysant leurs institutions et les pratiques. A partir d'une approche relationnelle, les sciences et les technologies sont conçues comme des phénomènes profondément sociaux, culturels et politiques. Une telle démarche déstabilise les visions parfois idéalisées et stéréotypées de la construction des savoirs. Des études de cas détaillées décrivent des phénomè...

  10. Negative incidental emotions augment fairness sensitivity.

    Liu, Cuizhen; Chai, Jing Wen; Yu, Rongjun

    2016-04-22

    Previous studies have shown that task-unrelated emotions induced incidentally exert carryover effects on individuals' subsequent decisions in financial negotiations. However, the specificity of these emotion effects are not clear. In three experiments, we systematically investigated the role of seven transiently induced basic emotions (disgust, sadness, anger, fear, happiness, surprise and neutral) on rejection of unfair offers using the ultimatum game. We found that all negative emotions (disgust, sadness, anger and fear), but not happiness or surprise, significantly increased rejection rates, suggesting that the effect of incidental negative emotions on fairness is not specific to the type of negative emotion. Our findings highlight the role of fleeting emotions in biasing decision-making processes and suggest that all incidental negative emotions exert similar effects on fairness sensitivity, possibly by potentiating attention towards negative aspects of the situation.

  11. IAS 41 Agriculture: Fair Value Accounting

    Viorel Lefter

    2007-05-01

    Full Text Available Issuing this standard that had to be applied for the first time for the financial statements started after 1.01.2003 meant a change of direction from two points of view: on one hand, through IAS 41 was issued for the first time an extensive standard typical for this sector and, on the other hand, for the first time were included in the income statement, independently from the sales transactions, incomes from variations of the fair value of an asset. Because of this last aspect, IAS 41 can be considered an important standard, because it represents the starting point of a consistent transition from the purchase cost principle towards a fair value accounting. IASC has dedicated to the thematic field of agriculture a specific standard, because this economic branch has a great importance for the developing countries. On the other hand, IAS 41 is also applied for the agricultural activities of the enterprises from other sectors.

  12. FAIR: a Horizon for Future Charming Physics

    Ritman, James

    2007-01-01

    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

  13. Antiproton chain of the FAIR storage rings

    2015-01-01

    In the Modularized Start Version of the Facility of Antiproton and Ion Research (FAIR) at Darmstadt Germany, the 3 GeV antiprotons are precooled in the collector ring and accumulated in the high energy storage ring (HESR). They are further accelerated to 14 GeV or decelerated to 1 GeV for the experiments with a high-density internal target. The powerful beam cooling devices, stochastic cooling and electron cooling will support the provision of a high-resolution antiproton beam. The other option of FAIR is to prepare the low energy, 300 keV antiproton beam connecting the existing storage rings ESR and CRYRING with HESR. Beam physics issues related with these concepts are described. (paper)

    2005-01-01

    The future Facility for Antiproton and Ion Research (FAIR) in Darmstadt will provide ideal conditions for a diverse research programme addressing various aspects of strongly interacting systems, fundamental interactions and dense plasmas. The projected complex combines two new synchrotrons with various storage rings, foresees cooling of beams and permits fixed target as well as in-beam experiments. This presentation will focus on the future research activities at FAIR, which can be grouped into 5 research areas: the structure and reactions of rare isotopes, hadron physics with brilliant antiproton beams, nuclear matter at high densities, atomic physics of antimatter and in strong electromagnetic fields, and laser as well as ion induced plasma physics. Emphasis will be put on the experimental installations addressing nuclear physics with relevance for astrophysics. (author)

  15. Strangeness fluctuations and MEMO production at FAIR

    Steinheimer, Jan; Mitrovski, Michael; Schuster, Tim; Petersen, Hannah; Bleicher, Marcus; Stoecker, Horst

    2009-01-01

    We apply a coupled transport-hydrodynamics model to discuss the production of multi-strange meta-stable objects in Pb + Pb reactions at the FAIR facility. In addition to making predictions for yields of these particles we are able to calculate particle dependent rapidity and momentum distributions. We argue that the FAIR energy regime is the optimal place to search for multi-strange baryonic object (due to the high baryon density, favoring a distillation of strangeness). Additionally, we show results for strangeness and baryon density fluctuations. Using the UrQMD model we calculate the strangeness separation in phase space which might lead to an enhanced production of MEMOs compared to models that assume global thermalization.

    Remplir 27 km de l’étroit tunnel du LEP avec plusieurs milliers d’équipements est le défi posé par le LHC et à relever par les techniciens et ingénieurs du CERN. Le LEP avait initié ce concept avec un outil nommé LEGO ; Le LHC a encore franchi une étape avec DMU (Digital Mock-Up), en tirant profit de l’évolution significative des outils informatiques (langages de programmation et logiciels). Utilisé comme interface entre une base de données Oracle® regroupant toutes les informations sur chaque équipement et les modèles 3D standard correspondants issus d’Euclid®, DMU a étendu, depuis, son champ d’application en permettant dorénavant de générer automatiquement tous les plans d’installation des 514 demi cellules de la Machine. Les évolutions futures de la configuration du LHC nous conduiront à modifier ou déplacer les équipements en place et à en insérer de nouveaux. Ceux-ci seront introduits dans la base de données avant de pouvoir être restitués via DMU sous forme de pl...

  19. Fairness and Trust in Structured Populations

    Corina E. Tarnita

    2015-07-01

    Full Text Available Classical economic theory assumes that people are rational and selfish, but behavioral experiments often point to inconsistent behavior, typically attributed to “other regarding preferences.” The Ultimatum Game, used to study fairness, and the Trust Game, used to study trust and trustworthiness, have been two of the most influential and well-studied examples of inconsistent behavior. Recently, evolutionary biologists have attempted to explain the evolution of such preferences using evolutionary game theoretic models. While deterministic evolutionary game theoretic models agree with the classical economics predictions, recent stochastic approaches that include uncertainty and the possibility of mistakes have been successful in accounting for both the evolution of fairness and the evolution of trust. Here I explore the role of population structure by generalizing and expanding these existing results to the case of non-random interactions. This is a natural extension since such interactions do not occur randomly in the daily lives of individuals. I find that, in the limit of weak selection, population structure increases the space of fair strategies that are selected for but it has little-to-no effect on the optimum strategy played in the Ultimatum Game. In the Trust Game, in the limit of weak selection, I find that some amount of trust and trustworthiness can evolve even in a well-mixed population; however, the optimal strategy, although trusting if the return on investment is sufficiently high, is never trustworthy. Population structure biases selection towards strategies that are both trusting and trustworthy trustworthy and reduces the critical return threshold, but, much like in the case of fairness, it does not affect the winning strategy. Further considering the effects of reputation and structure, I find that they act synergistically to promote the evolution of trustworthiness.

  3. [Statement of fair retribution in medical oaths].

    Pérez, Marta L; Rancich, Ana M; Gelpi, Ricardo J

    2004-01-01

    to determine if Medical Oaths from different times include the statement of the physician to request from patients a fair retribution for his/her medical services. Fifty Medical Oaths found in articles and publications were analyzed. In accordance with their corresponding dates, the Oaths were grouped as ancient /medieval (12), and modern/contemporary (38). Of the fifty, only three specifically included the statement of fair retribution. Two of the three were medieval and belonged to the School of Medicine of Montpellier. The other text was modern (Amato Lusitano's Oath). Four writings showed statements regarding medical assistance to the poor. Eleven pledges indirectly stated that no earnings from other activities and/or relations were obtained. Ancient oaths emphasize fair retribution, no discrimination in medical assistance based on payment possibilities, and gain of honest earnings. Modern oaths generally do not include these topics and very few mention that the medical profession should not be exercised merely for material purposes. Despite the above, physicians should respect the limits of their obligations and should be committed to assist without discriminating, particularly without taking into consideration their patient's financial possibilities. Therefore their fees should not be excessive for the services rendered.

  4. Fair packet scheduling in Wireless Mesh Networks

    Nawab, Faisal

    2014-02-01

    In this paper we study the interactions of TCP and IEEE 802.11 MAC in Wireless Mesh Networks (WMNs). We use a Markov chain to capture the behavior of TCP sessions, particularly the impact on network throughput due to the effect of queue utilization and packet relaying. A closed form solution is derived to numerically determine the throughput. Based on the developed model, we propose a distributed MAC protocol called Timestamp-ordered MAC (TMAC), aiming to alleviate the unfairness problem in WMNs. TMAC extends CSMA/CA by scheduling data packets based on their age. Prior to transmitting a data packet, a transmitter broadcasts a request control message appended with a timestamp to a selected list of neighbors. It can proceed with the transmission only if it receives a sufficient number of grant control messages from these neighbors. A grant message indicates that the associated data packet has the lowest timestamp of all the packets pending transmission at the local transmit queue. We demonstrate that a loose ordering of timestamps among neighboring nodes is sufficient for enforcing local fairness, subsequently leading to flow rate fairness in a multi-hop WMN. We show that TMAC can be implemented using the control frames in IEEE 802.11, and thus can be easily integrated in existing 802.11-based WMNs. Our simulation results show that TMAC achieves excellent resource allocation fairness while maintaining over 90% of maximum link capacity across a large number of topologies.

  5. The Compressed Baryonic Matter experiment at FAIR

    Höhne Claudia

    2018-01-01

    Full Text Available The CBM experiment will investigate highly compressed baryonic matter created in A+A collisions at the new FAIR research center. With a beam energy range up to 11 AGeV for the heaviest nuclei at the SIS 100 accelerator, CBM will investigate the QCD phase diagram in the intermediate range, i.e. at moderate temperatures but high net-baryon densities. This intermediate range of the QCD phase diagram is of particular interest, because a first order phase transition ending in a critical point and possibly new highdensity phases of strongly interacting matter are expected. In this range of the QCD phase diagram only exploratory measurements have been performed so far. CBM, as a next generation, high-luminosity experiment, will substantially improve our knowledge of matter created in this region of the QCD phase diagram and characterize its properties by measuring rare probes such as multi-strange hyperons, dileptons or charm, but also with event-by-event fluctuations of conserved quantities, and collective flow of identified particles. The experimental preparations with special focus on hadronic observables and strangeness is presented in terms of detector development, feasibility studies and fast track reconstruction. Preparations are progressing well such that CBM will be ready with FAIR start. As quite some detectors are ready before, they will be used as upgrades or extensions of already running experiments allowing for a rich physics program prior to FAIR start.

    2015-01-01

    To explore cosmic matter in the laboratory - this fascinating research prospect becomes available at the Facility for Antiproton and Ion Research, FAIR. The new facility is being constructed within the next five years adjacent to the existing accelerator complex of the GSI Helmholtz Centre for Heavy Ion Research at Darmstadt/Germany, expanding the research goals and technical possibilities substantially. This includes new insights into the dynamics of supernovae depending on the properties of short-lived neutron-rich nuclei which will be investigated with intense rare isotope beams. New insights will be provided into the interior of stars by exploring dense plasmas with intense heavy-ion beams combined with a high-performance laser - or into neutron star cores by probing the highest baryon densities in relativistic nucleus-nucleus collisions at unprecedented collision rates. To the latter, the properties of hadrons play an important part which will be systematically studied by high precision hadron spectroscopy with antiproton beams at unmatched intensities. The worldwide unique accelerator and experimental facilities of FAIR will open the way for a broad spectrum of unprecedented fore-front research supplying a large variety of experiments in hadron, nuclear, atomic and plasma physics as well as biomedical and material science which will be briefly described in this article.

  10. Etude de la performance des radars hautes-frequences CODAR et WERA pour la mesure des courants marins en presence partielle de glace de mer

    Kamli, Emna

    Les radars hautes-frequences (RHF) mesurent les courants marins de surface avec une portee pouvant atteindre 200 kilometres et une resolution de l'ordre du kilometre. Cette etude a pour but de caracteriser la performance des RHF, en terme de couverture spatiale, pour la mesure des courants de surface en presence partielle de glace de mer. Pour ce faire, les mesures des courants de deux radars de type CODAR sur la rive sud de l'estuaire maritime du Saint-Laurent, et d'un radar de type WERA sur la rive nord, prises pendant l'hiver 2013, ont ete utilisees. Dans un premier temps, l'aire moyenne journaliere de la zone ou les courants sont mesures par chaque radar a ete comparee a l'energie des vagues de Bragg calculee a partir des donnees brutes d'acceleration fournies par une bouee mouillee dans la zone couverte par les radars. La couverture des CODARs est dependante de la densite d'energie de Bragg, alors que la couverture du WERA y est pratiquement insensible. Un modele de fetch appele GENER a ete force par la vitesse du vent predite par le modele GEM d'Environnement Canada pour estimer la hauteur significative ainsi que la periode modale des vagues. A partir de ces parametres, la densite d'energie des vagues de Bragg a ete evaluee pendant l'hiver a l'aide du spectre theorique de Bretschneider. Ces resultats permettent d'etablir la couverture normale de chaque radar en absence de glace de mer. La concentration de glace de mer, predite par le systeme canadien operationnel de prevision glace-ocean, a ete moyennee sur les differents fetchs du vent selon la direction moyenne journaliere des vagues predites par GENER. Dans un deuxieme temps, la relation entre le ratio des couvertures journalieres obtenues pendant l'hiver 2013 et des couvertures normales de chaque radar d'une part, et la concentration moyenne journaliere de glace de mer d'autre part, a ete etablie. Le ratio des couvertures decroit avec l'augmentation de la concentration de glace de mer pour les deux types

    electrons de 15 MeV emis par un betatron. Les auteurs presentent les resultats d'une etude autoradiographique sur le comportement de differentes categories de cellules de thymus chez la souris, etude dans laquelle ils ont utilise de la thymidine tritiee comme precurseur de l'ADN. Les donnees sont fonction des modifications du nombre relatif des diverses categories de cellules (par taille), ainsi que du poids de l'organe. Apres irradiation, la proportion des grandes cellules par rapport aux petites augmente; l'incorporation de thymidine tritiee diminue au niveau des grands et petits lymphocytes. Dans la phase aiguee, on n'observe aucune difference notable entre l'effet des rayons X et celui des electrons sur les dimensions des cellules et sur le marquage des grandes cellules. Une modification relative apparait pour le marquage des petites cellules; ce phenomene, qui peut avoir un rapport avec les valeurs EBR des electrons rapides, concorde avec les donnees relatives au poids de l'organe. Pendant la regeneration, les cellules moins differenciees presentent une proliferation active, mais le pourcentage des lymphocytes arrives a maturation reste faible. Apres exposition a des electrons de 15 MeV, la proliferation des grandes cellules est plus active, suivant les courbes d'atrophie du thymus en fonction du temps. D'apres les resultats ci-dessus, il semblerait que le pouvoir de regeneration depende de l'importance des lesions subies par les cellules primitives; pour une dose donnee, ces lesions semblent plus marquees apres exposition aux rayons X qu'apres exposition aux electrons.
