    Coronary artery disease is one of the primary cause of mortality worldwide. Nuclear medicine is the major imaging technique for diagnosis and following of this disease. perfusion: nowadays, major radioactive agents used in clinical practice are myocardial perfusion tracers. The reference tracer is thallium-201. However, {sup 201}Tl presents some drawbacks. {sup 99m}Tcn-noet has been proposed for its replacement. This study shows that in contrast with previous studies realized in vitro on cardio myocytes, verapamil, an l-type calcium channel inhibitor, does not inhibit myocardial fixation of {sup 99m}Tcn-noet in vivo in dog. This data is in agreement with the hypothesis of a non specific endothelial fixation of this tracer. Moreover, this study shows that as a pure tracer of myocardial perfusion, {sup 99m}Tcn-noet can also be used to assess myocardial viability on a model of myocardial chronic infarction in rat. atherosclerosis: disruption of vulnerable atherosclerotic plaques is the main event leading to coronary accidents. The second part of this study concerns the evaluation of new potential tracers of the vulnerable atherosclerotic plaque in an experimental model of rabbit with an inheritable hypercholesterolemia. The four tracers evaluated (b2702(r), b2702-I, b2702-Tc and Tc-raft-b2702) are synthetic peptides comprising the residues 75-84 of hla-b2702, a molecule known to link vcam-1, an adhesion molecule expressed in vulnerable atherosclerotic plaque. The autoradiography studies show that all tracers accumulate within atherosclerotic plaque expressing vcam- and that. i-b2702 shows the best plaque/control fixation ratio. (author)

    Full Text Available Il est maintenant bien établi que les triglycérides plasmatiques représentent un facteur de risque indépendant d’athérosclérose et des maladies cardiovasculaires qui en découlent [1]. L’hypertriglycéridémie est connue pour être associée à une surexpression des apolipoprotéines CIII (apoCIII. Les quantités et la distribution de ces apoCIII dans le plasma sont essentielles dans le métabolisme des triglycérides, et il existe de nombreuses études épidémiologiques mettant en évidence leur association avec le développement et la progression des lésions d’athérosclérose dans les maladies cardio-vasculaires (MCV. Les apoCIII et plus particulièrement les apoCIII liées aux particules riches en triglycérides sont considérées comme de nouveaux marqueurs/facteurs de risque des MCV associés aux triglycérides comme cela a été étudié et rapporté par P. Alaupovic dans l’article précédent [2]. En outre, un certain nombre de sujets jeunes ayant fait un accident ischémique grave, présentent un bilan lipidique considéré comme normal et qui ne permet pas de les identifier. Mais on sait aussi que des sujets coronariens, normolipidémiques à jeun, peuvent présenter un retard d’épuration postprandiale des triglycérides, détectable seulement après un repas test riche en graisses [3-5]. Les retards d’épuration postprandiaux et leur toxicité sont imputés aux chylomicrons remnants qui persistent trop longtemps dans la circulation et sont considérés comme très athérogènes [6]. Dans un travail préliminaire [7], nous avions comparé un petit groupe de sujets normolipidémiques à jeun (n = 10 mais présentant une maladie coronarienne précoce (groupe CAD et montré l’existence d’anomalies du métabolisme lipidique postprandial par comparaison à un groupe de sujets contrôles.

    Liver fluke disease is a chronic parasitic inflammatory disease of the bile ducts. Infection occurs through ingestion of fluke-infested, fresh-water raw fish. The most well-known species that cause human infection are Clonorchis sinensis, Opisthorchis viverrini and Opisthorchis felineus. Adult flukes settle in the small intrahepatic bile ducts and then they live there for 20-30 years. The long-lived flukes cause long-lasting chronic inflammation of the bile ducts and this produces epithelial hyperplasia, periductal fibrosis and bile duct dilatation. The vast majority of patients are asymptomatic, but the patients with heavy infection suffer from lassitude and nonspecific abdominal complaints. The complications are stone formation, recurrent pyogenic cholangitis and cholangiocarcinoma. Approximately 35 million people are infected with liver flukes throughout the world and the exceptionally high incidence of cholangiocarcinoma in some endemic areas is closely related with a high prevalence of liver fluke infection. Considering the impact of this food-borne malady on public health and the severe possible clinical consequences, liver fluke infection should not be forgotten or neglected.

    Full Text Available Conjoined twins are a very rare entity. It is associated with poor survival rate in the presence of vital organ sharing. The entity can be diagnosed as early as the first trimester. A conjoined twin diagnosed late in labor is a malady with high perinatal mortality and maternal morbidity. We present one such case of xiphopagus twins. The management of a case diagnosed late in labor can be very challenging. Such obstetric challenges can be avoided by a meticulous early scan with a high index of suspicion, especially in the absence of separating membrane while scanning multiple pregnancies.

  14. Victoria Ocampo and Alfonso Reyes: Ulysses's Malady

    Directory of Open Access Journals (Sweden)

    2000-06-01

    Full Text Available Ocampo (Argentina, 1890-1979 and Reyes (Mexico, 1889-1959 were arguably Latin America's most influential writers and cultural catalysts in the first half of the twentieth century. They met in Argentina in 1927 and their friendship and correspondence lasted until Reyes's death. Over three decades of private and public discourse, they articulated a similar vision of Latin American identity and its future potential. Because they were both internationally known—Ocampo as founder and director of the literary review SUR, and Reyes as a diplomat and intellectual leader—their ideas found resonance in the Americas and Europe. Two dramatic works they wrote before meeting, Ifigenia cruel (Reyes and La laguna de los nenúfares (Ocampo, prefigure their approach to the Latin American condition through the themes of displacement and self-renovation. Ocampo and Reyes believed that it would be the task of an educated elite to lead Latin America toward a transnational cultural synthesis and renewal. Ulysses's malady was their metaphor for the postcolonial condition that enabled Latin American minds to be open to exploration and dialogue in search of an authentic identity.

    Résumé Objectif Passer en revue les facteurs de risque, la prise en charge et la prévention des maladies reliées aux loisirs aquatiques en pratique familiale. Sources des données Des articles originaux et de synthèse entre janvier 1998 et février 2012 ont été identifiés à l’aide de PubMed et des expressions de recherche en anglais water-related illness, recreational water illness et swimmer illness. Message principal Il y a un risque de 3 % à 8 % de maladies gastrointestinales (MGI) après la baignade. Les groupes à risque élevé de MGI sont les enfants de moins de 5 ans, surtout s’ils n’ont pas été vaccinés contre le rotavirus, les personnes âgées et les patients immunodéficients. Les enfants sont à plus grand risque parce qu’ils avalent plus d’eau quand ils nagent, restent dans l’eau plus longtemps et jouent dans l’eau peu profonde et le sable qui sont plus contaminés. Les adeptes des sports dans lesquels le contact avec l’eau est abondant comme le triathlon et le surf cerf-volant sont aussi à risque élevé et même ceux qui s’adonnent à des activités impliquant un contact partiel avec l’eau comme la navigation de plaisance et la pêche ont un risque de 40 % à 50 % fois plus grand de MGI par rapport à ceux qui ne pratiquent pas de sports aquatiques. Il y a lieu de faire une culture des selles quand on soupçonne une maladie reliée aux loisirs aquatiques et l’échelle clinique de la déshydratation est utile pour l’évaluation des besoins de traitement chez les enfants affectés. Conclusion Les maladies reliées aux loisirs aquatiques est la principale cause de MGI durant la saison des baignades. La reconnaissance que la baignade est une source importante de maladies peut aider à prévenir les cas récurrents et secondaires. On recommande fortement le vaccin contre le rotavirus chez les enfants qui se baignent souvent.

    The health of heads of states is not always handled in the same way as an incapacitating disability in ordinary professionals. Instead of suspension of responsibilities, the health status of political leaders is concealed, especially when the illness is perceived as stigmatizing, such as organic mental impairment or sexual disorder. The objective of the present paper is to analyse the malady of Lenin (1870-1924) in the light of relevant and new medical information. It is hoped that this will accentuate the need for transparency when the health of a statesman is concerned.

    2010-08-01

    Coinage of terms like nutraceuticals, functional, and pharma foods has diverted the attention of human beings to where they are seeking more natural cures. Though pharmaceutical drugs have been beneficial for human health and have cured various diseases but they also impart some side effects. Numerous plants have been tested for their therapeutic potential; Nigella sativa, commonly known as black cumin, is one of them. It possesses a nutritional dense profile as its fixed oil (lipid fraction), is rich in unsaturated fatty acids while essential oil contains thymoquinone and carvacrol as antioxidants. N. sativa seeds also contain proteins, alkaloids (nigellicines and nigelledine), and saponins (alpha-hederin) in substantial amounts. Recent pharmacological investigations suggested its potential role, especially for the amelioration of oxidative stress through free radical scavenging activity, the induction of apoptosis to cure various cancer lines, the reduction of blood glucose, and the prevention of complications from diabetes. It regulates hematological and serological aspects and can be effective in dyslipidemia and respiratory disorders. Moreover, its immunopotentiating and immunomodulating role brings balance in the immune system. Evidence is available supporting the utilization of Nigella sativa and its bioactive components in a daily diet for health improvement. This review is intended to focus on the composition of Nigella sativa and to elaborate its possible therapeutic roles as a functional food to prevent an array of maladies.

    Résumé Objectif Répondre aux questions souvent posées par les généralistes et aux difficultés auxquelles ils font face lorsqu’ils prescrivent des tests sérologiques pour la maladie cœliaque et fournir des conseils pratiques pour aider à interpréter les résultats des tests. Sources de l’information Une recherche a été effectuée dans MEDLINE pour les lignes directrices sur le diagnostic et la prise en charge de la maladie cœliaque publiées en anglais entre 2000 et 2015 par des organisations professionnelles de gastro-entérologie. Message principal Pour dépister la maladie cœliaque, le dosage de l’anticorps immunoglobuline A (IgA) anti-transglutaminase tissulaire est le test de choix. Il faut mesurer le taux sérique d’IgA totale afin d’écarter un déficit sélectif en IgA et d’éviter les faux négatifs. Les patients dont le test sérologique est positif doivent être recommandés à un gastro-entérologue pour subir des biopsies de l’intestin grêle par endoscopie afin de confirmer le diagnostic. Le typage des antigènes des leucocytes humains DQ2 et DQ8 peut aider à écarter le diagnostic. Un régime sans gluten ne doit pas être entrepris avant que le diagnostic de maladie cœliaque soit confirmé. Conclusion Les tests sérologiques sont très utiles pour confirmer les soupçons d’une maladie cœliaque. Le diagnostic précoce est essentiel pour prévenir les complications liées à la maladie cœliaque.

  6. Hypothesis: the chaos and complexity theory may help our understanding of fibromyalgia and similar maladies.

    2008-02-01

    Modern clinicians are often frustrated by their inability to understand fibromyalgia and similar maladies since these illnesses cannot be explained by the prevailing linear-reductionist medical paradigm. This article proposes that new concepts derived from the Complexity Theory may help understand the pathogenesis of fibromyalgia, chronic fatigue syndrome, and Gulf War syndrome. This hypothesis is based on the recent recognition of chaos fractals and complex systems in human physiology. These nonlinear dynamics concepts offer a different perspective to the notion of homeostasis and disease. They propose that the essence of disease is dysfunction and not structural damage. Studies using novel nonlinear instruments have shown that fibromyalgia and similar maladies may be caused by the degraded performance of our main complex adaptive system. This dysfunction explains the multifaceted manifestations of these entities. To understand and alleviate the suffering associated with these complex illnesses, a paradigm shift from reductionism to holism based on the Complexity Theory is suggested. This shift perceives health as resilient adaptation and some chronic illnesses as rigid dysfunction.

    Certain members of the personnel residing in France have recently received a letter, addressed to themselves and/or their spouse, from the French health insurance authorities (Assurance Maladie) on the subject of changes in the health insurance coverage of “frontalier” workers.   It should be recalled that employed members of personnel (MPE) are not affected by the changes made by the French authorities to frontalier  workers' "right to choose" (droit d'option) in matters of health insurance (see the CHIS website for more details), which took effect as of 1 June 2014, as they are not considered to be frontalier workers. Associated members of the personnel (MPA) are not affected either, unless they live in France and are employed by a Swiss institute. For the small number of MPAs in the latter category who might be affected, as well as for family members who do have frontalier status, CERN is still in discussion with the authorities o...

    Les manifestations pleuro-pulmonaires de la maladie de Horton sont rares et peu connues. Elles peuvent être inaugurales, à l'origine d'un retard à la prise en charge si elles sont méconnues. Il s'agissait d'un patient âgé de 75 ans, admis pour une dyspnée, une toux chronique et une fièvre. Il a reçu une antibiothérapie et a bénéficié d'une fibroscopie bronchique avec lavage broncho-alvéolaire à la recherche d'un germe, qui a révélé plutôt, une alvéolite lymphocytaire. L’évolution était marquée par la persistance des signes cliniques et du syndrome inflammatoire biologique. Un angio-scanner thoracique et une échographie cardiaque étaient sans anomalies. Une origine cardiaque, musculaire, hématologique, néoplasique, vasculaire ou métabolique de la dyspnée a été éliminée. Une maladie de Horton a été évoquée. La biopsie de l'artère temporale a confirmé le diagnostic d'une maladie de Horton. L’évolution sous corticothérapie était marquée par la disparition des signes cliniques et biologiques. Les manifestations pleuro-pulmonaires au cours de la maladie de Horton sont rares, et classiquement, rarement révélatrices de la maladie. La dyspnée peut initialement égarer le diagnostic vers d'autres étiologies notamment infectieuses. Le but de ce travail est d'insister sur le fait que la connaissance de ces différentes manifestations respiratoires au cours de la maladie de Horton (toux persistante, dyspnée, épanchement pleural) est utile au clinicien afin de prescrire une corticothérapie, chez un sujet le plus souvent âgé ayant un état fébrile et inflammatoire prolongé, permettant ainsi d’éviter l'apparition de complications.

  11. PLACE DU MEDECIN GENERALISTE, EN FRANCE, DANS LE PARCOURS DE SOINS DES MALADIES CHRONIQUES

    2017-05-01

    Full Text Available Les maladies chroniques sont la première cause de décès et la source principale des dépenses de santé. Leur dépistage précoce devrait permettre de limiter leur gravité évolutive et de réduire sensiblement leur coût.Le médecin généraliste est le mieux placé pour assurer la prise en charge de ces affections tout au long du parcours de soins. Mais plusieurs obstacles limitent cette évidence : la diminution régulière du nombre de praticiens de premier recours affectant de nombreux bassins de santé en France,  mais aussi, pour ceux en activité, des difficultés tenant au manque de formation, de temps médical et à une rémunération inadaptée à la prise en charge de ces pathologies. De ce fait, la prévention des maladies chroniques est insuffisante, leur diagnostic souvent trop tardif,  tandis que leur suivi se heurte au défaut d’observance du traitement par le patient et, plus rarement, à l’inertie thérapeutique médicale.   C'est pourquoi, il faut revoir fondamentalement la prise en charge des patients  pour les rendre autonomes dans la gestion de leur affection tout en donnant au praticien les moyens de gérer et de coordonner efficacement les diverses étapes du parcours de soin. Cela exige de changer les mentalités de part et d'autre, mais aussi de donner au médecin les moyens financiers lui permettant de consacrer à ses patients plus de temps, au centre d'une nouvelle organisation interprofessionnelle. La prévention et l’éducation thérapeutique du patient (ETP sont les clés de cette révolution thérapeutique. Il convient, en outre,  de revoir la formation des étudiants en privilégiant les sciences humaines et les stages chez le praticien, en favorisant  un accès accru au numérique et en assurant la reconnaissance, par des mesures concrètes, de la place du médecin généraliste dans un nouveau parcours de soins où il doit avoir un rôle central de coordinateur.

    Full Text Available Si La vitamine D est connue depuis près d’un siècle pour son action antirachitique, depuis quelques années de nombreux travaux mettent en évidence l’implication de la vitamine D dans le développement des maladies auto-immunes (psoriasis, asthme, diabète de type 1..., sensibilité au virus (tuberculose, grippe, bronchiolite... ou de cancers. La forme active de la vitamine D, la 1,25-(OH2D joue un rôle immunomodulateur complexe associant : (1 une activation des systèmes non spécifiques de défense immunitaire, en favorisant la différenciation et les activités cytotoxiques des monocytes-macrophages; et (2 une inhibition des systèmes de défense immunitaire antigènes-spécifiques, en diminuant la fonction de présentation des antigènes des monocytes, en modulant la prolifération et les activités des lymphocytes T et B, et en favorisant le maintien ou la restauration de la fonction immunosuppressive des lymphocytes. Ces actions permettent d’expliquer les effets préventifs de la 1,25-(OH2D sur le développement des maladies auto-immunes ou le rejet des hétérogreffes chez l’animal. La synthèse d’analogues ayant les mêmes activités immunomodulatrices que la 1,25-(OH2D, tout en étant moins hypercalcémiants, ouvre des perspectives intéressantes pour cette prévention en clinique humaine. La question qui reste ouverte porte sur les niveaux de vitamine D à recommander car les niveaux de vitamine D (25(OHD nécessaire pour observer ce rôle protecteur sont beaucoup plus élevés que les niveaux pour maintenir une santé osseuse optimale. Il faudrait largement augmenter les supplémentations. Toute la difficulté réside dans le fait que ces supplémentations élevées peuvent s’associer à des signes d’hypercalcémie. L’autre question est « qui supplémenter » : à quel âge, à quelle dose ?

  14. Interdisciplinarity in health services research: dreams and nightmares, maladies and remedies.

    Science.gov (United States)

    Giacomini, Mita

    2004-07-01

    Interdisciplinarity has become popular in health services research. Advocates suggest that interdisciplinary approaches may produce more accessible, applicable, exciting and realistic knowledge than traditional disciplinary approaches. To date, there has been surprisingly little analysis of the institutional and intellectual demands of interdisciplinarity as a methodology or practice. This paper (1) identifies some basic intellectual and institutional features of interdisciplinary research, (2) describes typical interdisciplinary 'dreams' and corresponding 'nightmares' that researchers might encounter in practice, (3) highlights maladies of interdisciplinary research careers and suggests practical remedies, and (4) discusses implications for health research policy. Individual researchers can avoid pitfalls of interdisciplinarity through strategies that include selective collaboration, cross-training, sustained relationships, good humour, participation in peer review, declaring the place of one's work, and balancing dissemination of research between peer and other audiences. Interdisciplinary activities span institutional boundaries and make novel demands on academic resources and allegiances. Research organizations can improve their hospitality to interdisciplinary work by encouraging straightforward communication, recognising interdisciplinary productivity, making allowances for the higher time and energy costs of interdisciplinary liaisons, and providing the necessary institutional support and stability to cultivate projects to fruition. Alongside the creation of large new interdisciplinary networks and organizations, we should invest in the highly valuable contributions of small and enduring interdisciplinary teams, modest interdisciplinary stretches and evolving interdisciplinary creatures.

  15. Conceptualiser l’addiction : entre l’écueil du mythe et celui de la maladie comme les autres

    2016-04-01

    Full Text Available La mise en évidence du statut de construction socioculturelle de l’addiction, le fait que l’on pourrait devenir addict à tout et la critique de la notion de perte de contrôle parlent, entre autres, en faveur d’un scepticisme vis-à-vis de l’addiction, auquel appartiennent ceux qui pensent que l’addiction consiste dans un choix pleinement assumé de l’individu, au sein d’un mode de vie. Une telle conception, empreinte ou non de moralisme, impute cependant une responsabilité à l’individu addict, un stigmate social ou moral très fort, synonyme d’un moins bon accès au soin. C’est pour contrecarrer cette stigmatisation que s’est instaurée une reconfiguration de l’addiction autour de la notion de maladie : si celle-ci n’est pas neuve, elle va depuis peu de pair avec l’ambition que les maladies mentales, a fortiori l’addiction, ne soient plus considérées comme des « maladies à part » mais « comme les autres » au même titre que le diabète, l’asthme ou le cancer. Dans cette optique, les neurosciences revêtent une importance particulière puisqu’elles offrent à la psychiatrie la possibilité de s’objectiver en identifiant les substrats organiques – neurobiologiques – des troubles mentaux. Mais la question se pose de savoir si une maladie a besoin d’être organique pour être dite réelle. Il nous semble que certains chercheurs, dans leur lutte contre le mythe de l’addiction, risquent de tomber dans l’écueil inverse de la normalisation des maladies mentales. En outre, même si nous n’adhérons pas à la conception sceptique de l’addiction, il y a cependant certains éléments – mis en évidence par les partisans de l’addiction comme mythe – que nous pensons devoir être pris en compte dans une enquête sur la nature de l’addiction.

A partir de l’énorme littérature épidémiologique sur le sujet, on peut conclure que la consommation de poisson « gras » ou d’oméga 3 à longue chaîne a un effet protecteur sur la mortalité coronaire et plus généralement sur les maladies cardiovasculaires. Il existe des indications en faveur d’un effet similaire de l’apport en alphalinolénique (ALA. Les essais de prévention secondaire avec des oméga 3 à longue chaîne ont confirmé ces résultats mais les essais de conseils nutritionnels favorisant la consommation d’ALA ne sont qu’indicatifs. Il n’existe guère « d’evidence » en faveur du rôle des oméga sur le développement quantitatif de l’athérome alors que leur effet protecteur sur la vulnérabilité cardiaque aux arythmies est bien établie. Ces données expérimentales et cliniques fournissent une base biologique à la relation observée entre un apport augmenté de poisson ou d’oméga 3 et un risque abaissé de mort subite dans plusieurs études de cohortes.

    Parmi les complications thrombotiques de la maladie cœliaque l'occlusion de la veine centrale de la rétine a été exceptionnellement décrite. Nous rapportons l'observation d'une patiente âgée de 27 ans chez qui le diagnostic de maladie cœliaque a été porté dans le cadre du bilan étiologique d'une occlusion de la veine centrale de la rétine. L'interrogatoire ne révélait pas de diarrhée chronique ou de douleurs abdominales. La présence d'un amaigrissement, d'une anémie ferriprive et d'une hypocholestérolémie ont permis l'orientation vers la maladie cœliaque. La positivité des anticorps anti endomysium et la biopsie duodénale montrant l'atrophie villositaire confirmaient ce diagnostic. Le régime sans gluten associé à un traitement par aspirine avait partiellement amélioré l'acuité visuelle chez notre patiente. Cette présentation atypique de la maladie cœliaque souligne la diversité des manifestations extra-digestives au cours de cette maladie et l'intérêt de penser à la maladie cœliaque même lorsque ces manifestations sont inaugurales.

L'épidémie de chikungunya, qui s'est déroulée de 2004 à 2006, est sans doute l'événement majeur de santé publique qui a marqué les hommes, les sociétés et les esprits aussi. Cette épidémie a touché les Etats et territoires de la région avec des prévalences de 25 à 60 %. Pour essayer de caractériser les contours de la vulnérabilité et déterminer des effets de contexte nous avons mené une analyse des niveaux de développement humain, social et sanitaire des pays concernés. S'il est établi que les facteurs d'émergence à l'échelle régionale sont très largement liés à des variables socio-spatiales néanmoins, à aléa égal le risque n’est pas proportionnellement plus important dans les pays réputés les plus vulnérables. A l'échelle de La Réunion, une analyse des données de l'environnement socio-spatial et épidémiologique, avec près de 3 000 cas géoréférencés durant la première phase de l'épidémie, permet d'établir les principaux quartiers à risques de l'île.Among the large amount of likely hazards in the South West of the Indian Ocean region (hurricanes, torrential rains, tsunamis, infectious diseases …, some are more devastating and present than others.

Les disfluences dans le discours spontané de ces deux groupes de sujets ont été analysées afin d’identifier les mots qui font l’objet de difficultés d’évocation. La complexité phonétique de ces occurrences problématiques et des occurrences non problématiques a été calculée à l’aide de l’Indice de complexité phonétique de Jakielski (2000. Les résultats montrent que les patients atteints de la maladie d’Alzheimer ont tendance à utiliser des mots de complexité phonétique plus faible que les personnes âgées saines et que les disfluences n’apparaissent pas de façon aléatoire, les occurrences problématiques (i.e. précédés d’une disfluence présentent un score de complexité phonétique plus élevé que pour les occurrences non problématiques. Cette étude montre que l’étude du langage dans la démence neurodégénérative, telle que la maladie d’Alzheimer, peut être utile pour affiner la connaissance sur la complexité linguistique et que l’Indice de complexité phonétique peut avoir un apport clinique en orthophonie pour une évaluation précise de la difficulté linguistique en prenant en compte le contexte phonétique de cette difficulté afin d’orienter les patients vers une remédiation adaptée.

    Full Text Available Introduction : Le Système canadien de surveillance des maladies chroniques (SCSMC de l’Agence de la santé publique du Canada utilise une méthode validée et normalisée pour estimer la prévalence des maladies chroniques, par exemple le diabète. L’élargissement de la portée du SCSMC pour inclure la surveillance de la multimorbidité et de la présence concomitante de deux maladies chroniques ou plus pourrait mieux guider la promotion de la santé et la prévention des maladies. L’objectif de notre étude était de déterminer s’il était possible de recourir au SCSMC pour estimer la prévalence de la multimorbidité. Méthodologie : Nous avons utilisé les données administratives sur la santé de sept provinces et de trois territoires portant sur cinq affections chroniques validées (maladies cardiovasculaires, maladies respiratoires, maladies mentales, hypertension et diabète pour estimer la prévalence de la multimorbidité. Nous avons produit des estimations normalisées selon l'âge et spécifiques selon l’âge (à l’aide des données démographiques canadiennes de 1991 pour deux définitions de la multimorbidité, soit deux affections ou plus ou trois affections ou plus sur les cinq affections validées, selon le sexe, la période et la zone géographique.

L'augmentation de la prévalence de la multimorbidité avec l’âge était similaire dans toutes les provinces. Les différences de prévalence entre hommes et femmes variaient selon les provinces et territoires. Nous avons également observé une variation importante des estimations au fil des années.

    Water is essential in providing nutrients, but contaminated water contributes to poor population health. Water quality and availability can change in unstructured situations, such as war. To develop a practical strategy to address poor water quality resulting from intermittent wars in Iraq, I reviewed information from academic sources regarding waterborne diseases, conflict and war, water quality treatment, and malnutrition. The prevalence of disease was high in impoverished, malnourished populations exposed to contaminated water sources. The data aided in developing a strategy to improve water quality in Iraq, which encompasses remineralized water from desalination plants, health care reform, monitoring and evaluation systems, and educational public health interventions.

Etude transversale cas témoin menée sur une durée de 16 mois. Ont été inclus 101 patients atteints de la maladie de Crohn, entre Janvier 2012 et Avril 2013 ainsi qu'un groupe contrôle de 107 patients. L'analyse génétique a consisté à rechercher 3 variants du gène NOD2: p.Arg702Trp, p.Gly908Arg et p.Leu1007fsins. Puis une étude de corrélation génotype-expression phénotypique a été menée. L'analyse génétique des patients atteint de maladie de crohn a mis en évidence la présence de la mutation NOD2 chez 14 patients (13,77%) contre 7 patients (6,53%) du groupe témoin. L'étude de la fréquence des différents allèles a retrouvé la mutation de p.Gly908Arg dans 6,43%, p.Leu1007fsins dans 0,99% et p.Arg702Trp dans 0,49% contre respectivement 2,80%, 0% et 0,46% dans le groupe témoin. L'étude de la corrélation génotype, expression phénotypique a démontré que la mutation CARD15 est corrélée à une localisation iléo-caecale de la maladie, à une présentation fistulisante et sténosante ainsi qu'à une évolution sévère avec recours fréquent à la chirurgie et aux immunosuppresseurs. La prévalence de la mutation NOD2/ CARD15 dans notre série est faible. Cette mutation est corrélée à une forme grave de la maladie. PMID:28819537

    2012-01-01

    Dans la première moitié du XXème siècle, alors que la Haute-Volta (actuel Burkina Faso) subissait une terrible épidémie de maladie du sommeil, l’administration coloniale française a orchestré des déplacements massifs de populations de la Haute-Volta vers la Côte d’Ivoire, pour exploiter le territoire. Cela a conduit à la mise en place de villages de colonisation Mossi en zone forestière ivoirienne, comme ceux de Koudougou, issus de l’une des régions les plus peuplées de Haute-Volta, mais aussi l’une des plus touchées par la maladie du sommeil. Depuis 2000, au Burkina Faso, c’est dans le district sanitaire de Koudougou que sont dépistés passivement le plus grand nombre de trypanosomés en provenance de Côte d’Ivoire. Qui sont-ils ?

    Full Text Available Dans la première moitié du XXème siècle, alors que la Haute-Volta (actuel Burkina Faso subissait une terrible épidémie de maladie du sommeil, l’administration coloniale française a orchestré des déplacements massifs de populations de la Haute-Volta vers la Côte d’Ivoire, pour exploiter le territoire. Cela a conduit à la mise en place de villages de colonisation Mossi en zone forestière ivoirienne, comme ceux de Koudougou, issus de l’une des régions les plus peuplées de Haute-Volta, mais aussi l’une des plus touchées par la maladie du sommeil. Depuis 2000, au Burkina Faso, c’est dans le district sanitaire de Koudougou que sont dépistés passivement le plus grand nombre de trypanosomés en provenance de Côte d’Ivoire. Qui sont-ils ?

  11. Heirs of Ambivalence: The Study of the Identity Crisis of the Second-Generation Indian Americans in Jhumpa Lahiri's Interpreter of Maladies

    Full Text Available Jhumpa Lahiri’s Interpreter of Maladies is a collection of short stories which, for the most part, deals with the identity crisis of the Indian Americans who are trapped in-between their Indian heritage and the American culture. The crisis is manifest in their unremitting struggle to preserve, to integrate, and to adjust. The collection, due to its dealing with the in-between-ness, ambivalence, hybridity, and marginality of the displaced Indian Americans, is receptive to the postcolonial studies. This essay draws on the relevant ideas and concepts in the field of the diaspora identity to examine Lahiri's “A Temporary Matter,” “When Mr. Pirzada Came to Dine,” “Sexy,” and “This Blessed House” which portray identity crisis of the second-generation Bengali migrants. The ultimate objective is to investigate into the nature of the internal ambivalence of Lahiri's second-generation characters caused by the reciprocal influence of Host/Guest relationships. The significance of the present study is twofold; on the one hand, it accentuates the intellectual attention to the crisis of identity felt by the exponentially increasing second-generation diaspora; on the other hand, it attempts to attract concentrated scholarly interest in diaspora ambivalence which is one of Lahiri scholars’ less addressed concerns.

    La maladie de Kaposi (MK) est une entité pathologique qui peut survenir chez les patients VIH positifs et dans le cadre d'une immunodépression, d'origine tuberculeuse très rarement. On décrit le cas d'une MK chez un patient VIH négatif au décours d'une tuberculose. Nous rapportons le cas d'un patient âgé de 81 ans, VIH négatif, ayant présenté deux nodules angiomateux de l'avant bras gauche dont la biopsie cutanée était en faveur d'une MK. L’évolution était marquée 2 mois plus tard, par l'apparition de placards angiomateux extensifs des deux membres supérieurs et d'adénopathies cervicales jugulo-carotidiennes bilatérales. La biopsie ganglionnaire était en faveur d'une tuberculose ganglionnaire. Par ailleurs, il avait un taux sérique élevé des CA 19-9. La régression de l’étendue des lésions au niveau des membres supérieurs et la normalisation du taux sérique des CA 19-9 ont été obtenues sous traitement anti-tuberculeux. Chez les patients atteints d'une MK avec une élévation des CA 19-9, il faut penser à la tuberculose. PMID:24711871

The number of accessions is now over 2 500, mostly of apples, pears and plums, all of which are planted in the open on dwarfing or semi-dwarfing rootstocks. One third of the material was recovered from old, often endangered collections in horticultural schools and to a minor extent from collections abroad, and two thirds from old orchards on faims and in gardens. A preference was given to material originated in Belgium either as landraces or as cultivars produced by recognized breeders from the part two centuries. The initial aim, which is still a priority, was to evaluate a broad range of old cultivars for useful characters, with an emphasis on disease resistance. As the collection expanded, a conservation objective also developed. From 1985 on, the Station started to reintroduce in the nursery trade and to recommend for home-growing the better cultivars emerging from the evaluation. Fifteen cultivars were released up to now, among which ten apples, four plums and one peach cv. Corresponding technical leaflets were also edited. The project had a multiform social impact ever since the outset. Both the collecting work and réintroduction process were a Ovide success with the public, which led a number of commercial growers to experiment with some of the recommended apple cultivars. As a further step in the utilization of genetic resources, the Station bas been producing yearly since 1988 several thousands of hybrid seedlings from interesting old apple cultivars with the aim of creating new material of commercial value with low disease susceptibility.

    Full Text Available The Bowen’s disease (MB, also known as squamous cell carcinoma in situ is a neoplastic skin disease that was clinically and histologically individualized by Darier in 1914. The isolated lesions in the majority of patients can be multiplied in 10 to 20% of cases. We report many locations which has posed problems of therapeutic choice. It is the case of a 35-year-old housewife, seen in consultation for red colored and squamous patches associated to pruritus and pain. On the skin, the examination found red colored and squamous patches, in projection, shaped rounded with a very slow evolution combining in a variable manner, rashes, scales, crusts and keratosis. Patches tended to grow progressively. The vulvar lesions were pigmented patches. In the mouth, we noted ulcers and a diffuse hypopigmentation with cheilitis, perlèche and odynophagia. The oncology checkup in search of another skin, mucosal and visceral cancer was done without any cancer found and the general condition was retained. The histopathology performed on two biopsies confirmed the diagnosis. Considering the spread of lesions and after a pretreatment evaluation, we put the patient under 5fluorouracil in cream on evening and under isotretinoin capsule with favorable evolution in the third week. The multiple sites of MB are rare but pose a management problem because of the evolutionary potential of each individual lesion in squamous cell carcinoma. The choice of treatment depends on the general condition of the patient, the expected efficacy of the treatment but also on its tolerance and cost.

    Glycohaemoglobin, and particularly haemoglobin A1c(HbA1c), assays have been used for many years to retrospectively evaluate the glycaemic control of diabetic patients. Cut-off values have been established for deciding treatment modifications. The techniques used in the laboratories however exhibit varying quality, and all of them are not yet standardized. The consequence is an under-utilization of this test, especially in non-hospital practice. In this context, working groups of Société Française de Biologie Clinique (SFBC), Association de Langue Française pour l'Etude du Diabète et des Maladies Métaboliques (ALFEDIAM) and Société Française d'Endocrinologie (SFE) have met together, in order to analyze the national status, and to propose practical recommendations for implementing a standardization process on the basis of international experiences. It is recommended to exclusively express results as HbA1c percentage, using methods standardized and certified by comparison to reference methods such as those using Diabetes Control and Complications Trial (DCCT) values. Simultaneously, contacts have been established with manufacturers, and the realisation of periodic quality control surveys was encouraged.

Ces mécanismes sont désormais bien connus grâce à la démarche expérimentale de laboratoire. L’enjeu actuel des recherches porte davantage sur l’analyse des processus d’émergence, de réémergence, de diffusion et de conservation de la peste, ce qui suppose de replacer la maladie dans son environnement, dans l’objectif de mieux la contrôler.

    In 1999, French legislators asked health insurance funds to develop a système national d'information interrégimes de l'Assurance Maladie (SNIIRAM) [national health insurance information system] in order to more precisely determine and evaluate health care utilization and health care expenditure of beneficiaries. These data, based on almost 66 million inhabitants in 2015, have already been the subject of numerous international publications on various topics: prevalence and incidence of diseases, patient care pathways, health status and health care utilization of specific populations, real-life use of drugs, assessment of adverse effects of drugs or other health care procedures, monitoring of national health insurance expenditure, etc. SNIIRAM comprises individual information on the sociodemographic and medical characteristics of beneficiaries and all hospital care and office medicine reimbursements, coded according to various systems. Access to data is controlled by permissions dependent on the type of data requested or used, their temporality and the researcher's status. In general, data can be analyzed by accredited agencies over a period covering the last three years plus the current year, and specific requests can be submitted to extract data over longer periods. A 1/97th random sample of SNIIRAM, the échantillon généraliste des bénéficiaires (EGB), representative of the national population of health insurance beneficiaries, was composed in 2005 to allow 20-year follow-up with facilitated access for medical research. The EGB is an open cohort, which includes new beneficiaries and newborn infants. SNIIRAM has continued to grow and extend to become, in 2016, the cornerstone of the future système national des données de santé (SNDS) [national health data system], which will gradually integrate new information (causes of death, social and medical data and complementary health insurance).

    The treatment of the basedow disease by iodine 131 is more and more used. however, the doses used stay variable. In order to reduce the treatment failure, we chose a protocol with strong fix doses of iodine 131. We give our preliminary results for 63 patients. The treatment by strong fix dose of iodine 131 is simple, safe and efficient for the control of hyperthyroidism in the Basedow disease. This protocol has for advantage to be simpler comparatively to these ones using adjusted doses according the weight of the thyroid and its fixation rate. (N.C.)

    Full Text Available This article investigates the ‘illness’ of King Saul (as narrated in the Old Testament. The ‘anti-Saul narrative’ states that ‘God’s spirit had left Saul’ and ‘an evil one had taken its place’ (1 Sm 16:14; also cf. e.g. of his behaviour in 1 Sm 19:24; 1 Sm 18:28−29. The latter years of Saul’s reign were marred by his pre-occupation with David’s growing popularity. He eventually became mentally unstable and suspected everyone of plotting against him. Saul’s battle against the Ammonites, as well as his last battle against the Philistines at Mount Gilboa, was fraught with difficulty. It is postulated that Saul experienced epileptic-like fits and assumedly suffered from some kind of ‘depression’ as a result of post-traumatic stress disorder (cf. 1 Sm 18:9; 1 Sm 18:28, 29; 1 Sm 19:24. This was possibly exacerbated by the enemy herem principle. Talmudic and other perspectives were also provided in the article where possible.

    Gossip is a natural part of every social setting and has a profound influence on organizational behaviors. As the primary care givers in the hospital setting, nurses are the front line in generating and controlling gossip. It is essential that management recognize this dynamic in the nursing workforce so they can be proactive in developing strategies to effectively control gossip. This article highlights the positive and negative aspects of gossip and provides strategies to help nursing professionals effectively manage this workplace issue. Unmanaged gossip can have a negative effect on the workplace by damaging relationships and reputations. Gossip that is managed effectively can have a positive effect on the workplace by building social bonds within the nursing unit.

    By definition, parasites cause harm to their hosts. But, considerable evidence from ancient traditional medicine has supported the theory of using parasites and their products in treating many diseases. Maggots have been used successfully to treat chronic, long-standing, infected wounds which failed to respond to conventional treatment by many beneficial effects on the wound including debridement, disinfection, and healing enhancement. Maggots are also applied in forensic medicine to estimate time between the death and discovery of a corpse and in entomotoxicology involving the potential use of insects as alternative samples for detecting drugs and toxins in death investigations. Leeches are segmented invertebrates, famous by their blood-feeding habits and used in phlebotomy to treat various ailments since ancient times. Leech therapy is experiencing resurgence nowadays in health care principally in plastic and reconstructive surgery. Earthworms provide a source of medicinally useful products with potential antimicrobial, antiviral, and anticancer properties. Lumbrokinases are a group of fibrinolytic enzymes isolated and purified from earthworms capable of degrading plasminogen-rich and plasminogen-free fibrin and so can be used to treat various conditions associated with thrombotic diseases. Helminth infection has been proved to have therapeutic effects in both animal and human clinical trials with promising evidence in treating many allergic diseases and can block the induction of or reduce the severity of some autoimmune disorders as Crohn's disease or ulcerative colitis. What is more, venomous arthropods such as scorpions, bees, wasps, spiders, ants, centipedes, snail, beetles, and caterpillars. The venoms and toxins from these arthropods provide a promising source of natural bioactive compounds which can be employed in the development of new drugs to treat diseases as cancer. The possibility of using these active molecules in biotechnological processes can make these venoms and toxins a valuable and promising source of natural bioactive compounds. The therapeutic use of helminthes and insects will be of great value in biomedicine and further studies on insect toxins will contribute extensively to the development of Biomedical Sciences.

    Résumé Objectif Présenter aux cliniciens une mise à jour sur le diagnostic de la maladie cœliaque (MC), ainsi que des recommandations sur les indications de procéder au dépistage de la MC chez les patients présentant une faible densité minérale osseuse (DMO) ou des fractures de fragilité. Qualité des données Un groupe de travail multidisciplinaire a élaboré des questions cliniquement pertinentes relativement au diagnostic de la MC servant de fondement à une recherche documentaire dans les bases de données MEDLINE, EMBASE et CENTRAL (de janvier 2000 à janvier 2009) à l’aide des mots clés en anglais celiac disease, osteoporosis, osteopenia, low bone mass et fracture. Les ouvrages scientifiques existants comportent des études de niveaux I et II. Message principal La prévalence estimée de la MC asymptomatique est de 2 % à 3 % chez les personnes qui ont une faible DMO. Par ailleurs, un dépistage ciblé est recommandé pour les patients qui ont des T-scores de −1,0 ou moins à la colonne vertébrale ou aux hanches ou des antécédents de fractures de fragilité associées à des symptômes ou à des problèmes reliés à la MC, des antécédents familiaux de MC ou de bas niveaux de calcium urinaire, une insuffisance en vitamine D et des niveaux à la hausse d’hormones parathyroïdiennes en dépit d’un apport suffisant en calcium et en vitamine D. Le dépistage de la MC devrait se faire pendant que le sujet consomme un régime alimentaire contenant du gluten. On procède au dépistage initial par le dosage d’immunoglobuline (Ig) A antitransglutaminase en utilisant la transglutaminase tissulaire humaine recombinante ou une autre transglutaminase tissulaire, en association avec l’immunofluorescence des IgA anti-endomysium. Une biopsie du duodénum est nécessaire pour confirmer le diagnostic de la MC. Le typage des antigènes des leucocytes humains peut aider à confirmer ou à exclure le diagnostic de la MC dans les cas où la s

    Full Text Available La surconsommation de sucres ajoutés et leurs effets putatifs sur diverses pathologies cardiométaboliques continuent de susciter des controverses. Dans les années 1950, le taux élevé de maladies cardiovasculaires (MCV, chez les hommes Américains a conduit à des études sur le rôle des facteurs alimentaires, tels que le cholestérol, les phytostérols, l'excès de calories, les acides aminés, les graisses, les glucides, les vitamines et les minéraux, à influencer le risque de MCV. Dans les années 60, deux éminents physiologistes, plaidant pour des hypothèses causales divergentes de MCV, John Yudkin a identifié les sucres ajoutés comme agent primaire, tandis que Ancel Keys identifiait les graisses totales, les graisses saturées et le cholestérol alimentaire. Cependant, dans les années 80, peu de scientifiques croyaient que les sucres ajoutés jouaient un rôle important dans la maladie coronarienne, et les premiers conseils nutritionnels de 1980 (1980 Dietary Guidelines for americans étaient axés sur la réduction des graisses totales, des graisses saturées et du cholestérol alimentaire pour la prévention des MCV.

Dans les maladies thyroiediennes, l'analyse des resultats confirme une difference significative entre les sujets temoins, les hypo et les hyperthyroidiens chez lesquels la consommation quotidienne d'hormones est tres abaissee ou au contraire augmentee. L'etude parallele de la capacite de transport de la thyroxine par la TBG et la TBPA autorise l'interpretation de ces variations qui semblent inversement proportionnelles a la quantite de thyroxine liee aux proteines vectrices du plasma. L'interet pratique de ce test doit etre souligne chez les sujets soumis as une surcharge par produit de contraste organo-iode et dans les formes atypiques de la maladie ou les investigations biologiques classiques sont d'interpretation difficile. Dans le diabete sucre, l'insulinotherapie augmente la quantite quotidiennement consommee de T{sub 4} et surtout de T{sub 3} tandis que les sulfamides hypoglycemiants ne paraissent avoir aucune incidence. Dans les syndromes nephrotiques, la vitesse de renouvellement de la T{sub 4} est accrue tandis que la clearance renale de cette hormone est tres elevee, a l'inverse de celle de la T{sub 3} moins liee aux proteines. Au cours de l'insuffisance renale, la vitesse de renouvellement de la T{sub 4} est tres abaissee tandis que son espace de dilution et son pool sont accrus. Ces resultats confirment l'interet de

    Allergic diseases are characterized by an immunoglobulin E (IgE)-dependent inflammatory reaction, presenting a type 2 cytokines profile (IL-4 and IL-5), and by the presence of eosinophils. The particulate pollution in urban areas comes mainly from diesel engines. Diesel particulates and their associated hydrocarbons, are probably involved in the recent increase of allergic pathologies thanks to their capability to induce a type-2 immune response. In this work, the effect of organic extracts of diesel particulates on the development of a Th2-type inflammatory response are analyzed, in particular by the evaluation of the synthesis modulation of chemokines, molecules known for their attraction capacities with respect to inflammatory cells, and of Th1 or Th2-type lymphocytes. It is shown that the exposure of mono-nucleated cells and alveolar macrophages from people allergic to diesel particulates induces a diminution of IP-10 production (pro-Th1), and in conjunction with the allergen, an increase of MDC (pro-Th2), mediated by the CD28 route. The functional consequence is an increased capability to attract human Th2 clones, non-completely inhibited by an anti-MDC neutralizing Ac, suggesting the participation of some other chemokines. Other analyses have shown that the diesel alone induces an I-309 production (pro-Th2) and that the diesel/allergen combination leads to a production of PARC (pro-Th2) but also of MIG (pro-Th1), the functional result being an attraction of Th2 cells again. In parallel and surprisingly, an increase of the expression of chemokine receptors expressed on Th1 cells has been evidenced, in particular the CXCR3, combined to a loss of its chemo-attractive power. These properties have been linked to a clearance function of the receptors with respect to their ligands. These results suggest that diesel can amplify a type-2 noxious response to allergic patients, firstly by inducing pro-Th2 chemokines, and secondly by facilitating the clearance of pro-Th1

    Full Text Available Introduction: The periodontal disease represents a malady characterized by an extremely high incidence. The manifestations and evolution of the periodontal diseases vary for each form in part, being influenced by systemic and local risk factors. Scope of the study: To evaluate the periodontal status on a group of patients, versus the syste‐ mic and local factors. Materials and method: The study was performed on a group of 170 patients, whose odonto‐periodontal status was evaluated by strict clinical and paraclinical examinations, on establishing the inflammation indices and the periodontal diagnosis. Results: The main cause of the analysis was gingival ble‐ eding; an increased number of smokers was registered among the patients. Out of the local factors, especially important were edentations and malocclusions. Also, a higher number of aggressive generalized periodontites has been noticed. Discussion: The forms of the periodontal diseases are obviously influenced by the systemic context, while the forms of localized chronic periodontitis associa‐ ted with generalized chronic gingivitis reflect the role pla‐ yed by the local risk factors. Conclusions: Stress and smoking represent significant risk factors in the installation of periodontal pathology, with a really alarming preva‐ lence. The aggressive forms of periodontitis showed a higher frequency than that recorded in literature.

    Evaluation of scientific work underlies the process of career advancement in academic science, with publications being a fundamental metric. Many aspects of the evaluation process for grants and promotions are deeply ingrained in institutions and funding agencies and have been altered very little in the past several decades, despite substantial changes that have taken place in the scientific work force, the funding landscape, and the way that science is being conducted. This article examines how scientific productivity is being evaluated, what it is rewarding, where it falls short, and why richer information than a standard curriculum vitae/biosketch might provide a more accurate picture of scientific and educational contributions. The article also explores how the evaluation process exerts a profound influence on many aspects of the scientific enterprise, including the training of new scientists, the way in which grant resources are distributed, the manner in which new knowledge is published, and the culture of science itself.

    Evaluating postoperative patients with hardware is challenging following surgical intervention for hip maladies such as femoral neck fractures and slipped capital femoral epiphysis (SCFE). These children are at increased risk of developing avascular necrosis, and imaging may be requested to confirm or exclude this diagnosis. Children with Legg-Calve-Perthes disease can be monitored for restoration of blood flow to the capital femoral epiphysis to guide management and help with prognosis. Although MRI is sensitive for detecting early avascular necrosis, the presence of hardware degrades image quality. This report examines the utility of bone scans for evaluating femoral head perfusion in children who have undergone surgery for femoral neck fractures, SCFE or Legg-Calve-Perthes disease. A retrospective review of 20 patients (22 scans) after fixation for femoral neck fracture, SCFE or Legg-Calve-Perthes disease from 2012 to 2015 was performed. The bone scan findings were correlated with the intraoperative findings or clinical follow-up. Twenty-one of the 22 (95%) bone scans in 19 of the 20 (95%) patients demonstrated findings consistent with clinical outcomes and/or the intraoperative appearance of the femoral head. Four of 20 patients (20%) had bone scan features of avascular necrosis, defined as ''absent'' or ''moderately diminished'' femoral head activity, which were confirmed intraoperatively and resulted in poor outcomes. Radionuclide imaging of hips in the postoperative setting is a valuable modality for assessing the risk of avascular necrosis, a complication of femoral neck fractures and SCFE and for evaluating the restoration of flow to the capital femoral epiphyses of children with Legg-Calve-Perthes disease.

    The purpose of this report was to analyse the efficacy and safety data of Stereotactic Body Radiation Therapy (SBRT) in patients with inoperable primary (hepatocellular carcinoma (HCC) and metastatic liver tumors (LM), to define the indications and the place of SBRT in the therapeutic strategy with the aim of its inclusion in the CCAM (French National list of reimbursement). The key points that arose from this assessment are the following: - The results are preliminary and the literature is inconclusive about safety and efficacy; - There are no standardised guidelines for: the indications, the eligibility criteria, the treatment protocols or the place of SBRT in the therapeutic strategy; - SBRT is a technique that requires great rigorous radioprotection and quality assurance procedures; the professionals and National institutions concerned recommend that SBRT only be performed in centres with sufficient resources, specific expertise and an organisation which guarantees that the quality assurance procedures will be respected. Recommendations HAS believes it is premature to recommend SBRT for the routine treatment of liver tumors and its reimbursement by the National Health Insurance (Assurance Maladie). HAS recommends its use in the strict context of clinical research by centres with sufficient resources, specific expertise and an organisation which guarantees that the quality assurance procedures will be respected. The literature search strategy prioritized randomised comparative studies and systematic reviews; If these were not available then non-randomised controlled trials, prospective studies were to be used and finally retrospective studies and case series were to be used. The assessment of SRBT for liver tumors was based on the critical analysis of clinical data from: - Three prospective case series, five retrospective case series, four health technology evaluation reports and 11 good practice recommendations, for primary liver tumors (HCC) - One prospective

    The use of evaluation results is at the core of evaluation theory and practice. Major debates in the field have emphasized the importance of both the evaluator’s role and the evaluation process itself in fostering evaluation use. A recent systematic review of interventions aimed at influencing policy-making or organizational behavior through knowledge exchange offers a new perspective on evaluation use. We propose here a framework for better understanding the embedded relations between evaluation context, choice of an evaluation model and use of results. The article argues that the evaluation context presents conditions that affect both the appropriateness of the evaluation model implemented and the use of results. PMID:23526460

    Full Text Available Saponins are pharmacologically active compounds that have been shown to ameliorate abnormal physiological processes and be aptly applied in folklore for the treatment of maladies occasioned by infectious agents. Consequently, saponins from Vitex doniana and Pentaclethra macrophylla were evaluated for antibacterial properties, as these herbs are used in folk medicine. Dried pulverized plant materials were defatted, and solvents with varying polarity were applied at varying ratios for the extraction of saponins. Phyto-chemistry was in accordance with standard methods, while an antibacterial assay was made through the agar well diffusion and micro broth dilution techniques. Phytochemical quantitation showed high concentrations of tannins, 231 ± 0.6 CE/g, and saponins, 58% from V. doniana. Similarly, P. macrophylla stem bark extract also showed high concentrations of tannins, 309 ± 2.42 CE/g, alkaloids, 71% ± 0.5%, and saponins, 87% ± 3.4%. The ethanol extracts of V. doniana inhibited the growth of Staphylococcus aureus (ATCC 11775 and a clinical strain with inhibition zone ranges of 15.5 ± 2.12 to 7.0 ± 0.0 (mm against leaf extracts and 20.0 ± 1.41 to 7.0 ± 0.0 (mm against stem bark extracts. Conversely, saponin extract from V. doniana showed a broad spectrum of activity, as it inhibited both Gram-negative and -positive test strains, E. coli clinical strain (20.0 ± 1.41 mm, P. aeruginosa clinical strain (18.5 ± 0.71 mm, E. coli ATCC 11775 (17.0 ± 0 mm, and S. aureus clinical strain (13.0 ± 1.41 mm. However, a broad spectrum was similarly achieved with P. macrophylla extracts, as all test bacteria genus was susceptible. Saponin fractions showed a high potency and broad spectrum antibacterial activity and thus a validation of the folklore applications and the potential for use as a drug or drug scaffold.

    reins) et la dose (qui ne doit etre ni trop elevee ni trop faible) representent les conditions determinantes d'une reproduction graphique correcte de la structure renale. Une mauvaise fixation de la radioactivite denote une insuffisance de l'activite tubulaire dans le parenchyme. La position, l'etendue.et la forme des zones de mauvaise fixation varient suivant le degre d'integrite des structures renales et leur alteration sous l'effet de divers processus pathologiques: tumeurs, kystes, hydro- nephrose, tuberculose, etc. Chez des sujets normaux, le scintigramme est generalement homogene, bien qu'il ne soit pas rare d'observer une plus faible densite dans la region du hile. Toute tache plus claire en dehors du hile indique une zone ou la fonction renale n'est pas normale. Parmi les images du rein plus grandes que la normale, il convient d'etablir une distinction entre les images homogenes, qui denotent une hypertrophie compensatoire, et les images non homogenes et irregulieres. Ces dernieres semblent indiquer une forte uronephrose ou la presence de tumeurs ou de kystes multiples. Dans les affections reno-vasculaires, le caractere de la fixation de la radioactivite dans les deux reins peut beaucoup aider a evaluer la diminution de la fonction renale et a etablir si un seul rein ou les deux sont atteints. On peut donc s'attendre que la scintigraphie du rein constituera une methode interessante d'exploration clinique, surtout en association avec l'examen radiologique des reins par les methodes classiques (urographie, pyeiographie ascendante, retropneumoperitoine, tomo- graphie, aortographie, etc.).

    2014-01-01

    This article investigates the European Union’s evaluation system and its conduciveness to evaluation use. Taking the European Commission’s LIFE programme as its case, the article makes an empirical contribution to an emerging focus in the literature on the importance of organization...... and institutions when analyzing evaluation use. By focusing on the European Union’s evaluation system the article finds that evaluation use mainly takes place in the European Commission and less so in the European Parliament and the European Council. The main explanatory factors enabling evaluation use relate...... to the system’s formalization of evaluation implementation and use; these factors ensure evaluation quality, timeliness and capacity in the Commission. At the same time, however, the system’s formalization also impedes evaluation use, reducing the direct influence of evaluations on policy-making and effectively...

  7. Bureaucrapathologies: Galloping Regulosis, Assessment Degradosis, and Other Unintended Organizational Maladies in Post-Graduate Medical Education.

    Yager, Joel; Katzman, Jeffrey E

    2015-12-01

    As decadelong observers of evolving administrative regulations governing academic medicine, the authors have identified several organizational disorders they define as "bureaucrapathologies," pathological conditions caused by dysfunctional bureaucratic processes that generate excesses of wasted time, effort, and other resources. Appearing wherever bureaucratic organizations exist, they have become particularly egregious in health care, research, and education. In past decades, graduate medical education has been beset by proliferating assessment requirements accompanied by corresponding documentation requirements imposed by academic educational regulatory agencies (specifically the Accreditation Council on Graduate Medical). Although originating from the best of intentions, these largely untested, unvalidated, and unfunded mandates generate burdensome personnel, time, and resource requirements. As they trickle down organizational levels, the intentions of the originators are inevitably degraded. As motivations and incentives of lower level administrators and faculty differ considerably from those at higher levels, we inevitably encounter debatable assessment practices yielding results of dubious reliability and validity. These processes invariably lead to proliferating reports and paperwork. All of this raises serious questions about the benefits vs. harms of these enterprises. In our view, these pathogenic processes can be recognized as diagnosable subtypes of bureaucrapathology. Here the authors briefly describe two, Galloping Regulosis and Assessment Degradosis, which reflect on their pathogenesis and offer preliminary thoughts for potential remedies. Several other recently identified bureaucrapathological syndromes awaiting future delineation are noted.

    Aleksandr Sergeyevich Pushkin (1799-1837) was one of the great figures of Russian poetry and literature. There are numerous publications about his life, adventures and creative work. However, little has been written about his character, mental state and the condition of his wound during his fatal duel. Furthermore, his sexual illnesses and their nature were discussed even less. This paper attempts to lift the veil from this mystery. © The Author(s) 2013.

    Idiopathic Parkinson's disease (PD) and Alzheimer's disease (AD) are the main neuro-degenerative diseases (NDDs) seen clinically. They share some common clinical symptoms and neuro-pathological findings. The increase of life expectancy in the developed countries will inevitably contribute to enhance the prevalence of these diseases. Behavioral disorders, common in NDDs, will produce major care management challenges. Idiopathic Parkinson's disease corresponds to a histopathological diagnosis, based on the observation of a de-pigmentation and a neuronal loss in the substantia nigra, as well as on the presence of intra-neuronal inclusion bodies. AD is insidious with slowly progressive dementia in which the decline in memory constitutes the main complaint. The diagnosis of definite AD requires the presence of clinical criteria as well as the histopathological confirmation of brain lesions. The two main lesions are the presence of senile plaques and neuro-fibrillary tangles. Positron emission tomography (PET) explores cerebral metabolism and neurotransmitter kinetics in NDDs using principally [{sup 18}F]-deoxyglucose and [{sup 18}F]-dopa. Nigrostriatal dopaminergic function is altered in PD, as evidenced by the low uptake of [{sup 18}F]-dopa in the posterior putamen as compared to anterior putamen and caudate nucleus. In contrast, [{sup 18}F]-dopa uptake is equally depressed in all striatal structures in progressive supra-nuclear palsy. Regional glucose metabolism at rest is preserved in elderly once cerebral atrophy is taken into account. On the contrary, glucose metabolism is globally reduced in AD, with marked decrease in the parietal and temporal regions. PET has proved to be useful to study in vivo neurochemical processes in patients suffering from NDDs. The potential of this approach is still largely unexploited, and depends on new ligand production to establish early diagnosis and treatment follow-up. (author)

    In Budapest at the end of the 19th century, visiting brothels was an important part of night life, including the risk of some venereal disease (v.d.) like syphilis, the in-vogue illness of the age. The expansion of prostitution could be explained with the continuous growth of economy and social development as a consequence of urbanization. Prostitution has grown in innumerable forms, levels and places in order to meet all requirements since this was the only tolerated form of sexuality "out of homes". The police headquarters' duty was to control the observation of rules prescribed for prostitutes. Data and information were available only on registered "professional" prostitutes because references on hidden prostitution were hard to find. Liberalization of the strict rules and regalements on brothels and "staff" began at the time when the increase of prostitution and simultaneously, of syphilis overreached the capacity of the Police and the Health Care System.

    2006-09-01

    The industrialization and urbanization of Britain during the 19th century gave the medical profession something to think about. In particular, were the radical changes taking place in society responsible for the sudden rise in endemic and epidemic disease? This article (part of the Science in the Industrial Revolution series) examines the reactions of two key figures in the history of British public health, James Philips Kay and Thomas Southwood Smith, to this question. Their outlooks typify the tendency of Victorian medical practitioners to construct economies of health that saw disease as a consequence of the violation of natural laws and cycles rather than as a product of industrial modernity.

  18. Evaluation of estrogenic potential of flavonoids using a recombinant yeast strain and MCF7/BUS cell proliferation assay.

    Directory of Open Access Journals (Sweden)

    Flávia A Resende

    Full Text Available Phytoestrogens are of interest because of their reported beneficial effects on many human maladies including cancer, neurodegeneration, cardiovascular disease and diabetes. Furthermore, there is a search for compounds with estrogenic activity that can replace estrogen in hormone replacement therapy during menopause, without the undesirable effects of estrogen, such as the elevation of breast cancer occurrence. Thus, the principal objective of this study was to assess the estrogenic activity of flavonoids with different hydroxylation patterns: quercetin, kaempferol, luteolin, fisetin, chrysin, galangin, flavone, 3-hydroxyflavone, 5-hydroxyflavone and 7-hydroxyflavone via two different in vitro assays, the recombinant yeast assay (RYA and the MCF-7 proliferation assay (E-screen, since the most potent phytoestrogens are members of the flavonoid family. In these assays, kaempferol was the only compound that showed ERα-dependent transcriptional activation activity by RYA, showing 6.74±1.7 nM EEQ, besides acting as a full agonist for the stimulation of proliferation of MCF-7/BUS cells. The other compounds did not show detectable levels of interaction with ER under the conditions used in the RYA. However, in the E-screen assay, compounds such as galangin, luteolin and fisetin also stimulated the proliferation of MCF-7/BUS cells, acting as partial agonists. In the evaluation of antiestrogenicity, the compounds quercetin, chrysin and 3-hydroxyflavone significantly inhibited the cell proliferation induced by 17-β-estradiol in the E-screen assay, indicating that these compounds may act as estrogen receptor antagonists. Overall, it became clear in the assay results that the estrogenic activity of flavonoids was affected by small structural differences such as the number of hydroxyl groups, especially those on the B ring of the flavonoid.

    Usability evaluation is widely accepted as a valuable activity in software development. However, how results effectively are fed back to developers is still a relatively unexplored area. We argue that usability feedback can be understood as an argument for a series of usability problems......, and that basic concepts from argumentation theory can help us understand how to create persuasive feedback. We revisit two field studies on usability feedback to study if concepts from Toulmin's model for argumentation and Aristotle's modes of persuasion can explain why some feedback formats outperform others....... We recommend that evaluators specifically back up the warrants behind their usability claims, that their arguments use several modes of persuasion, and that they present feedback in browsable amounts not to overwhelm developers with information. For complex and controversial problems, we advise...

    Failure of a transplanted kidney may be caused by any of several factors requiring different methods of management. It is thus necessary to distinguish between rejection, acute tubular necrosis, obstruction of the main blood vessels in the graft, and obstruction of the ureter. Careful evaluation is particularly important when cadaver kidneys are used, for which the functional 2-year survival rate is only 40-50%, compared with 70-80% for living related donor kidneys. Formerly renal transplant angiography was often performed to differentiate between acute rejection and acute ischemic tubular necrosis as the cause of graft dysfunction in the immediate postoperative period. Now, however, angiography for the patient with a failing graft is restricted mainly to the search for renal artery stenosis and arterial or renal vein thrombosis. Although the study may be specific when a full-blown pattern of rejection is present, routine angiography has proved to be of little value when rejection is suspected

    The value of a preoperative chest radiograph is twofold. The examination may reveal unsuspected pathology that would alter the approach to surgery of anesthesia. Secondly, it provides a baseline or reference from which to evaluate subsequent post-operative films. The percentage of detection of unsuspected pathology on preoperative chest radiographs has been shown to be exceedingly small in certain patient populations. The authors do not recommend routine use of preoperative chest radiographs in children or in adults under the age of 40 who do not smoke, unless (1) the surgical disease has chest manifestations; (2) there is historic or clinical evidence of a coexisting disease with chest involvement; or (3) there is a likelihood that post-operative management will require follow-up films

    1995-01-23

    An in-depth analysis of the RTAP product was undertaken within the CNC associate program to determine the feasibility of utilizing it to replace the current Supervisory Control System that supports the AVLIS program. This document contains the results of that evaluation. With some fundamental redesign the current Supervisory Control system could meet the needs described above. The redesign would require a large amount of software rewriting and would be very time consuming. The higher level functionality (alarming, automation, etc.) would have to wait until its completion. Our current understanding and preliminary testing indicate that using commercial software is the best way to get these new features at the minimum cost to the program. Additional savings will be obtained by moving the maintenance costs of the basic control system from in-house to commercial industry and allowing our developers to concentrate on the unique control areas that require customization. Our current operating system, VMS, has become a hindrance. The UNIX operating system has become the choice for most scientific and engineering systems and we should follow suit. As a result of the commercial system survey referenced above we selected RTAP, a SCADA product developed by Hewlett Packard (HP), as the most favorable product to replace the current supervisory system in AVLIS. It is an extremely open system, with a large, well defined Application Programming Interface (API). This will allow the seamless integration of unique front end devices in the laser area (e.g. Optical Device Controller). RTAP also possesses various functionality that is lacking in our current system: integrated alarming, real-time configurable database, system scalability, and a Sequence Control Language (SQL developed by CPU, an RTAP Channel Partner) that will facilitate the automation necessary to bring the AVLIS process to plant-line operation. It runs on HP-9000, DEC-Alpha, IBM-RS6000 and Sun Workstations.

Cet article propose donc un résumé critique de cette singulière polémique: l'ouvrage Darkness in El Dorado et les réactions qu'il a suscitées sont ici examinés. Notre attention va plus particulièrement porter sur un thème central: la pénétration des objets manufacturés occidentaux parmi les Yanomami et ses - conséquences. Par l'étude de question dépassant cependant la seule 'yanomamologie'- la guerre indigène, la rétribution des informateurs, etc.-, cette focalisation permettra notamment de remettre en cause plusieurs conclusion de Tierney et de critiquer les sources dont il fait un usage abondant. Les conséquences de cette controverse pou l'éthique anthropologique seront finalement exposées. EPIDEMIAS, ARTÍCULOS MANUFACTURADOS, GUERRAS... Y LA ÉTICA EN DISCUSIÓN: NOTA SOBRE EL CASO TIERNEY. Casi tres años después del comienzo de la “polémica Tierney”, controversia que ha hecho derramar mucha tinta, con notable excepción del mundo francófono sobre el particular, ya es hora de hacer un balance al menos de caracter provisorio. Este artículo quiere proponer un resumen crítico de esta polémica: Darkness in El Dorado y los comentarios que ha originado están examinados. La atención está particularmente centrada sobre un tema esencial del libro: la introducción de artículos manufacturados occidentales entre los Yanomami y sus consecuencias. Con el estudio de temas que adelantan la ‘yanomamologia’ -la guerra indígena, la retribución de los informantes, etc.-, esta focalización puede, entre otras cosas, cuestionar las conclusiones de Tierney y criticar las fuentes utilizadas por este autor. Por último, las consecuencias de esta controversia para la ética antropológica están expuestas. EPIDEMICS, ITEMS, WARS... AND ETHIC UNDER DISCUSSION: A NOTE ABOUT TIERNEY AFFAIR. Since it first started over three years ago, the so-called “Tierney affair” has elicited a spectacular amount of commentary throughout the world. However, the French-speaking public has been poorly informed about the controversy surrounding Darkness in Eldorado and the reactions it provoked. This paper attempts to fill in this gap. Emphasis is placed on one of the book’s central themes: the consequences of the massive introduction of manufactured goods among the Yanomami. The validity of many of Tierney’s assumptions, as well as his questionable use of written sources, will be examined in the light of general Amazonian ethnology, especially regarding such questions as native warfare and the impact of informant retribution. The implications of this controversy for anthropological ethics is also highlighted here.

  6. A tale of two maladies? Pathogenesis of depression with and without the Huntington’s disease gene mutation

    Full Text Available Huntington’s disease (HD is an autosomal dominant disorder caused by a tandem repeat expansion encoding an expanded tract of glutamines in the huntingtin protein. HD is progressive and manifests as psychiatric symptoms (including depression, cognitive deficits (culminating in dementia and motor abnormalities (including chorea. Having reached the 20th anniversary of the discovery of the ‘genetic stutter’ which causes HD, we still lack sophisticated insight into why so many HD patients exhibit affective disorders such as depression at very early stages, prior to overt appearance of motor deficits. In this review, we will focus on depression as the major psychiatric manifestation of HD, discuss potential mechanisms of pathogenesis identified from animal models, and compare depression in HD patients with that of the wider gene-negative population. The discovery of depressive-like behaviours as well as cellular and molecular correlates of depression in transgenic HD mice has added strong support to the hypothesis that the HD mutation adds significantly to the genetic load for depression. A key question is whether HD-associated depression differs from that in the general population. Whilst preclinical studies, clinical data and treatment responses suggest striking similarities, there are also some apparent differences. We discuss various molecular and cellular mechanisms which may contribute to depression in HD, and whether they may generalise to other depressive disorders. The autosomal dominant nature of HD and the existence of models with excellent construct validity provide a unique opportunity to understand the pathogenesis of depression and associated gene-environment interactions. Thus, understanding the pathogenesis of depression in HD may not only facilitate tailored therapeutic approaches for HD sufferers, but may also translate to the clinical depression which devastates the lives of so many people.

  8. Stratégies des planteurs de cocotiers au Ghana face à la maladie du jaunissement mortel

    Directory of Open Access Journals (Sweden)

    2009-03-01

    Full Text Available In Ghana, coconut developed extensively during the 1960s, 1970s and 1980s in the coastal strip of the “Western” region. Subsequently, many coconut plantations disappeared as they were progressively affected by lethal yellowing disease. The response of the planters was to stop investing in coconut, then, after an interval of a few years, to start diversifying by planting oil palm, cocoa and rubber. At the same time, villages located further inland, which were untouched by the disease, continued to produce coconut. Between these two areas, in the “heart” of the coconut production region around Jomoro, coconut plantations were not affected by the disease, but were aging and undergoing a decrease in yield. The result of these developments was the relocation of production centres, which is the subject of analysis in this paper. We used a model that was developed for other perennial crops in conditions of almost complete monoculture, particularly cocoa. The model revealed a pattern of regional cycles succeeding one another that are relatively independent of changes in coconut prices. The cycles are based on the exhaustion of natural resources as a source of income, and on the concurrence of the life cycle of the plantation and that of family life. The model was first successfully tested on the situation of coconut in Ghana before 2005-2006. In 2005-2006, a major economic upheaval occurred. The arrival of Nigerian buyers helped cause a 50% increase in the price of coconut. Prices continued to rise in 2007. From a strictly technical and economic point of view, given the prices offered by Nigerian buyers, the cultivation of hybrid coconut, which is less vulnerable than the local coconut, again appeared to be very profitable, with a risk factor that was acceptable in regions not affected by the disease. These economic conditions enabled us to check what the model would predict in the case of a rise in prices, which was that in coconut production areas, the response would be very limited, i.e. the opposite of what classical theory predicts. In fact, in areas of aging monocrops, a rise in prices no longer has much effect. The model explained the real state of affairs at the regional scale: the recession of the previously leading crop is almost inevitable. On the other hand, a favourable response to the rise in prices is possible in districts and provinces in Ghana (and in Côte d’Ivoire that have not been affected by the disease, thus reinforcing the process of relocation of production centres. This structural relocation could mean a new future for coconut in Ghana in the context of expanding regional demand in Nigeria, Burkina Faso and Mali. Yet the end of research, the end of the production of planting material, the lack of low-interest credit, (a precondition for re-investment, and finally, the abandonment of coconut planters by public policies, has left thousands of families and particularly old people, trapped in a spiral of recession which the rise in the price of coconut will not break.

    Full Text Available Les préoccupations sont croissantes pour étudier les liens entre des conditions environnementales spécifiques et la fréquence de certaines pathologies. Nous proposons d’analyser ici le lien présupposé entre une exposition au radon et le cancer du poumon. Le radon, est un gaz radioactif d’origine naturelle (issu de la désintégration naturelle de l’uranium présent dans la croûte terrestre et plus particulièrement dans certaines formations géologiques. A partir du sol et de l’eau, le radon se diffuse dans l’air (exhalation et se trouve, par effet de confinement, à des concentrations plus élevées à l’intérieur des bâtiments qu’à l’extérieur. Les descendants solides du radon sont alors inhalés avec l’air respiré et se déposent dans le poumon. Il est établi par diverses études scientifiques que le radon a un impact non négligeable sur certains cancers, notamment du poumon (augmentation de 16 % du risque de cancer du poumon par tranche de 100 Bq/m3, et des cancers digestifs via la consommation d’eau qui s’est chargée en radon au contact du socle. Le nombre annuel de décès par cancer du poumon attribuable à l’exposition domestique au radon en France métropolitaine varie entre 1 200 à 3 575 en fonction des relations exposition-réponse utilisées. Plusieurs régions en France se caractérisent par une problématique radon reconnue et étudiée depuis longtemps (Bretagne, Massif central, Corse. Or, si le radon ne recouvre pas l’ensemble de la région PACA, certaines zones géographiques sont particulièrement concernées et méritent d’être étudiées : le Massif des Maures dans le Var, du Mercantour dans les Alpes-Maritimes et du Briançonnais dans les Hautes-Alpes. La région PACA est une des régions de France et d’Europe les plus touchées par la pollution atmosphérique principalement due à l’augmentation du trafic routier et des contributions de régions industrialisées telles que la vallée du Pô, l’Etang de Berre... ainsi qu’au climat méditerranéen chaud. Du fait de cette caractéristique, le radon a souvent été relégué au second plan par rapport aux polluants les plus communs. Néanmoins, il a été établit que le radon du fait de ses spécificités (accumulation en milieu intérieur, gaz naturel inodore représente un risque trop souvent négligé à prendre en compte de toute urgence dans certaines zones.

    Full Text Available Bone abnormalities are common in theropod dinosaur skeletons, but before now no specimen was known with more than four afflicted bones of the pectoral girdle and/or forelimb. Here we describe the pathology of a specimen of the theropod dinosaur Dilophosaurus wetherilli with eight afflicted bones of the pectoral girdle and forelimb. On its left side the animal has a fractured scapula and radius and large fibriscesses in the ulna and the proximal thumb phalanx. On its right side the animal has abnormal torsion of the humeral shaft, bony tumors on the radius, a truncated distal articular surface of metacarpal III, and angular deformities of the first phalanx of the third finger. Healing and remodeling indicates that the animal survived for months and possibly years after its ailments began, but its right third finger was permanently deformed and lacked the capability of flexion. The deformities of the humerus and the right third finger may be due to developmental osteodysplasia, a condition known in extant birds but unreported in non-avian dinosaurs before now.

    2005-02-01

    Alexander Ivanov was an outstanding Russian painter who lived in the middle of the nineteenth century, during the romantic period. He did not accept romanticism but instead tried to create his own original style, an ambitious combination of spiritual profundity and a manner of execution unparalleled in Western European art. Ivanov's intention and style are best reflected in his major work The Appearance of Christ to the People, a picture on which he worked for over 20 years. He painted more than 400 sketches of the picture while attempting to bring his masterpiece to perfection. At the end of his life Ivanov became disillusioned, renounced his strong religious conviction and became suspicious. This study examines the influence of his background, life story and personality on the creative process. From a diagnostic perspective, Ivanov's personality featured obsessive, narcissistic and schizoid traits. In his final years he suffered from a delusional disorder.

The objective of this retrospective observational study was to study the long-term outcome of exercise capacity and quality of life during management of patients with COPD treated by home-based PR.Methods: Home-based PR was administered to 211 patients with COPD (mean age, 62.3±11.1 years; mean forced expiratory volume in 1 second, 41.5%±17.7%. Home-based PR was chosen because of the distance of the patient’s home from the PR center and the patient’s preference. Each patient was individually managed by a team member once a week for 8 weeks with unsupervised continuation of physical exercises on the other days of the week according to an individual action plan. Exercise conditioning, therapeutic patient education, and self-management were included in the PR program. The home assessment comprised evaluation of the patient’s exercise capacity by a 6-minute stepper test, Timed Up and Go test, ten times sit-to-stand test, Hospital Anxiety and Depression score, and quality of life (Visual Simplified Respiratory Questionnaire, VQ11, Maugeri Respiratory Failure 28.Results: No incidents or accidents were observed during the course of home-based PR.

    This evaluation was conducted over an eight-month period from February 4 through October 1, 1980. During this time, field sampling was suspended for an indefinite time period while the National Uranium Resource Evaluation (NURE) Program underwent restructuring. In addition, the Uranium Resource Evaluation (URE) Project archives are being restructured. Since it is difficult to evaluate quality assurance needs of a program that is undergoing drastic change and because sections of the evaluation were well along before these changes were announced, this evaluation reflects the situation as it was during February 1980. The following quality assurance related programs are continuing to date: (1) periodic checks of field sampling procedures by the Supervising Field Geologist and the Director of Field Operations; (2) verification of field form information and laboratory analytical data verification for all geochemical surveys; (3) URE Project laboratory quality control program (all elements routinely analyzed); and (4) Ames interlaboratory quality control program (uranium only). UCC-ND was given the responsibility of conducting a Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) survey in the Central United States (Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Nebraska, North Dakota, Oklahoma, Texas, South Dakota, and Wisconsin). During 1979 and 1980, 13 detailed surveys were conducted by the URE Project in the Central and Western United States to characterize the hydrogeochemistry, stream sediment geochemistry, and/or radiometric patterns of known or potential uranium occurrences. Beginning in 1980, the HSSR surveys were modified to the Regional Hydrogeochemical and Stream Sediment (RHSS) surveys

The paper will present the ''what, where, who, when, and why'' of a new Evaluation Program. The Evaluation Program will be comprised of a continuing series of regular and special evaluations of DOE safeguards and security programs and policies. The evaluations will be integrative and ''crosscutting,'' i.e. will extend across DOE organizational lines. Evaluations will be offered as positive advisories to DOE managers with safeguards and security responsibilities and will not be rated. They will complement the ongoing OSE Inspection Program of inspections conducted by OSE's Inspection Division. The purpose for the evaluations is to establish an accurate and current assessment of the effectiveness and status of safeguards and security programs and policies and to provide DOE managers with required information on program and policy effectiveness

    2006-01-01

    This lecture is devoted to the nuclear data evaluation process, during which the current knowledge (experimental or theoretical) of nuclear reactions is condensed and synthesised into a computer file (the evaluated data file) that application codes can process and use for simulation calculations. After an overview of the content of evaluated nuclear data files, we describe the different methods used for evaluating nuclear data. We specifically focus on the model based approach which we use to evaluate data in the continuum region. A few examples, coming from the day to day practice of data evaluation will illustrate this lecture. Finally, we will discuss the most likely perspectives for improvement of the evaluation process in the next decade. (author)

  19. Evaluating psychodiagnostic decisions.

    Witteman, Cilia L M; Harries, Clare; Bekker, Hilary L; Van Aarle, Edward J M

    2007-02-01

    Several frameworks can be used to evaluate decision making. These may relate to different aspects of the decision-making process, or concern the decision outcome. Evaluations of psychodiagnostic decisions have shown diagnosticians to be poor decision makers. In this essay we argue that this finding results from the evaluation of only one part of the diagnostic process. We put forward that evaluations are typically carried out by comparing clinicians' behaviour to one of several normative models, for example hypothetico-deductive reasoning. These models make strong assumptions about human reasoning capabilities, which make it almost impossible for people to measure up to them. The subsequent two parts of the psychodiagnostic process (causal explanation and treatment decisions), are typically not included in these evaluation studies. Treatment decisions are evaluated in effectiveness studies; that is, they are evaluated in terms of their outcomes, not in terms of the diagnosticians' decision processes. Psychodiagnosticians' causal explanation has hardly ever been the subject of evaluation. We argue that in order to achieve clinical excellence, this part of the psychodiagnostic process should also be well understood. In this essay we first describe evaluation of psychodiagnostic decision making. We then propose a framework to describe causal explanation, that is, a situation assessment in terms of a causal schema or a story or script. We identify and discuss the tools available for evaluating this part of the psychodiagnostic process.

    Research purpose: The purpose of this special edition is to introduce readers to the evaluation of human resource (HR programmes. Motivation for the study: There are few comprehensive evaluations of HR programmes despite many publications on functional efficiency measures of HR (i.e. measures of cost, time, quantity, error and quality. Research design, approach and method: This article provides a value chain for HR activities and introduces the reader to programme theory-driven evaluation. Main findings: In summarising all of the contributions in this edition, one of the main findings was the lack of programme evaluation experience within HR functions and the difficulty this posed for the evaluators. Practical/managerial implications: This introductory article presents answers to two simple questions: What does HR do? and, What is programme evaluation? These answers will enable practitioners to understand what programme evaluators mean when we say that programme evaluation seeks to determine the merit of a programme. Contribution/value-add: The main contribution of this introductory article is to set the scene for the HR evaluations that follow. It alerts the reader to the rich theory contribution in HR literature and how to apply this in a theory-driven evaluation.

    A covariance evaluation system for the evaluated nuclear data library was established. The parameter estimation method and the least squares method with a spline function are used to generate the covariance data. Uncertainties of nuclear reaction model parameters are estimated from experimental data uncertainties, then the covariance of the evaluated cross sections is calculated by means of error propagation. Computer programs ELIESE-3, EGNASH4, ECIS, and CASTHY are used. Covariances of 238 U reaction cross sections were calculated with this system. (author)

    The binational Eulerian Model Evaluation Field Study (EMEFS) consisted of several coordinated data gathering and model evaluation activities. In the EMEFS, data were collected by five air and precipitation monitoring networks between June 1988 and June 1990. Model evaluation is continuing. This interim report summarizes the progress made in the evaluation of the Regional Acid Deposition Model (RADM) and the Acid Deposition and Oxidant Model (ADOM) through the December 1990 completion of a State of Science and Technology report on model evaluation for the National Acid Precipitation Assessment Program (NAPAP). Because various assessment applications of RADM had to be evaluated for NAPAP, the report emphasizes the RADM component of the evaluation. A protocol for the evaluation was developed by the model evaluation team and defined the observed and predicted values to be used and the methods by which the observed and predicted values were to be compared. Scatter plots and time series of predicted and observed values were used to present the comparisons graphically. Difference statistics and correlations were used to quantify model performance. 64 refs., 34 figs., 6 tabs

    2015-12-01

    Full Text Available This article provides a discussion on the question of validity in qualitative evaluation. Although validity in qualitative inquiry has been widely reflected upon in the methodological literature (and is still often subject of debate, the link with evaluation research is underexplored. Elaborating on epistemological and theoretical conceptualizations by Guba and Lincoln and Creswell and Miller, the article explores aspects of validity of qualitative research with the explicit objective of connecting them with aspects of evaluation in social policy. It argues that different purposes of qualitative evaluations can be linked with different scientific paradigms and perspectives, thus transcending unproductive paradigmatic divisions as well as providing a flexible yet rigorous validity framework for researchers and reviewers of qualitative evaluations.

    Moed, Henk F

    2017-01-01

    This book focuses on applied evaluative informetric artifacts or topics. It explains the base notions and assumptions of evaluative informetrics by discussing a series of important applications. The structure of the book is therefore not organized by methodological characteristics, but is centered around popular, often discussed or used informetric artifacts - indicators, methodologies, products, databases - or so called hot topics in which informetric indicators play an important role. Most of the artifacts and topics emerged during the past decade. The principal aim of the book is to present a state of the art in applied evaluative informetrics, and to inform the readers about the pros and cons, potentialities and limitations of the use of informetric/bibliometric indicators in research assessment. The book is a continuation of the book Citation Analysis in Research Evaluation (Springer, 2005). It is of interest to non-specialists, especially research students at advanced master level and higher, all thos...

    We present DUE (Distributed Usability Evaluation), a technique for collecting and evaluating usability data. The DUE infrastructure involves a client-server network. A client-based tool resides on the workstation of each user, providing a screen video recording, microphone input of voice commentary......, and a window for a severity rating. The idea is for the user to work naturalistically, clicking a button when a usability problem or point of uncertainty is encountered, to describe it verbally along with illustrating it on screen, and to rate its severity. These incidents are accumulated on a server......, providing access to an evaluator (usability expert) and to product developers or managers who want to review the incidents and analyse them. DUE supports evaluation in the development stages from running prototypes and onwards. A case study of the use of DUE in a corporate environment is presented...

    The paper describes a software inspection process that can be used to evaluate the quality of software components. Quality criteria, process application, independent testing of the process and proposed associated tool support are covered. Early results indicate that this technique is well suited for assessing software component quality in a standardized fashion. With automated machine assistance to facilitate both the evaluation and selection of software components, such a technique should promote effective reuse of software components.

  9. Strengthening safeguards information evaluation

    International Nuclear Information System (INIS)

    Harry, J.; Hudson, P.

    2001-01-01

    The strengthening of safeguards should not be limited to the verification of explicit declarations made by the States. Additional information should guide the IAEA to set priorities for further investigations. Not only all aspects of the State's nuclear programme, including the application of safe, secure and transparent nuclear management, but also the level of compliance with other verifiable treaties, political motivation, economic capabilities, international relations and ties, co-operative attitude to safeguards, and general openness and transparency should be included. The evaluation of the diverse forms of information from different sources requires new reliable processes that will result in a high credibility and detection probability. The IAEA uses the physical model for the evaluation of the technical information, and proposed also Fuzzy Logic, or Calculation with Words, to handle the information. But for the evaluation it is questioned whether fuzziness could lead to a crisp judgement. In this paper an objective method of information evaluation is proposed, which allows to integrate different kinds of information and to include calibration and tests in the establishment of the evaluation process. This method, Delta, uses elicitation of a syndicate of experienced inspectors to integrate obvious indicators together with apparently innocent indicators, into a database that forms the core of the evaluation process. Nominal or ordinal scales could be applied to come to an objective and quantifiable result. Experience with this method can in the course of time result in predictive conclusions. 9 refs

    Oblozinsky, P.; Oblozinsky,P.; Herman,M.; Mughabghab,S.F.

    2010-10-01

    This chapter describes the current status of evaluated nuclear data for nuclear technology applications. We start with evaluation procedures for neutron-induced reactions focusing on incident energies from the thermal energy up to 20 MeV, though higher energies are also mentioned. This is followed by examining the status of evaluated neutron data for actinides that play dominant role in most of the applications, followed by coolants/moderators, structural materials and fission products. We then discuss neutron covariance data that characterize uncertainties and correlations. We explain how modern nuclear evaluated data libraries are validated against an extensive set of integral benchmark experiments. Afterwards, we briefly examine other data of importance for nuclear technology, including fission yields, thermal neutron scattering and decay data. A description of three major evaluated nuclear data libraries is provided, including the latest version of the US library ENDF/B-VII.0, European JEFF-3.1 and Japanese JENDL-3.3. A brief introduction is made to current web retrieval systems that allow easy access to a vast amount of up-to-date evaluated nuclear data for nuclear technology applications.

  11. Evaluation of systematic I-131 thyroid measurements for nuclear medicine workers

    Puscalau, M.A.

    2002-01-01

    In Nuclear Medicine, I-131 is used intensively for the diagnosis and for the treatment of the different severities maladies of the thyroid. This radionuclide generates an important internal contamination to the patients, because of its oral administration, and, also, through inhalation, to the workers involved in the radiopharmaceuticals production , to the nursing staff and to the physicians that care and treat the patients in the hospitals. The paper presents the data obtained by systematically thyroid monitoring of the physicians and nurses from the Endocrinology Hospital, that are contaminated by I-131 inhalation because of their permanent relation with the patients treated with 3.7 MBq I-131 for investigation and with activities in the range 1100 MBq - 4000 MBq for therapy. The measurements were carried out with our Body Counter equipped with a NaI(Tl) scintillation detector, 50 mm thickness and 40mm diameter. Values of the estimated committed equivalent doses are, also, reported

    2002-01-01

    The purpose of this study is to respond to U.S. Department of Energy (DOE) Technical Direction Letter (TDL) 02-003 (Waisley 2001), which directs Bechtel SAIC Company, LLC (BSC) to complete a design study to recommend repository design options to support receipt and/or emplacement of any or all of the following: commercial spent nuclear fuel (CSNF), high-level radioactive waste (HLW), DOE-managed spent nuclear fuel (DSNF) (including naval spent nuclear fuel [SNF]), and immobilized plutonium (if available), as soon as practicable, but no later than 2010. From the possible design options, a recommended approach will be determined for further evaluation to support the preliminary design of the repository. This study integrates the results of the repository Design Evolution Study (Rowe 2002) with supporting studies concerning national transportation options (BSC 2002b) and Nevada transportation options (Gehner 2002). The repository Design Evolution Study documents the processes used to reevaluate the design, construction, operation, and cost of the repository in response to TDL 02-003 (Waisley 2001), and to determine possible repository conceptual design options. The transportation studies evaluate the national and Nevada transportation options that support the repository conceptual design options. An evaluation methodology was established, based on Program-level requirements developed for the study in reference BSC 2001a, to allow the repository and system design options to be evaluated on a consistent basis. The transportation options and the design components were integrated into system design implementation options, which were evaluated using receipt and emplacement scenarios. The scenarios tested the ability of the design concept to adapt to changes in funding, waste receipt rate, and Nevada rail transportation availability. The results of the evaluation (in terms of system throughput, cost, and schedule) were then compared to the Program-level requirements, and

    Full Text Available In a world experiencing profound technological and socio-political changes in areas of knowledge and capacity, healthcare can not remain static. A new kind of professional is required, whose practice is based on ethics, scientific standards, integrity, citizenship, and health promotion, who develops skills beyond healthcare, such as decision making, communication,leadership, management, and continuing education. No single method can assess all of these elements (knowledge, skills, and attitudes, and only a combination of methods is able to produce a valid evaluation. An alternative method exists: structured clinical assessments based on observation of "to do, or how to do" that aim to complete this evaluation by focusing attention on the performance of specific skills. In order to broaden the scope of evaluation methods that have been used in health education, this article, a literature review, intends to offer readers an overview of the diverse types of structured clinical evaluation, emphasizing Objective Structured Clinical Examination, the most widely used in Brazil, with a goal of advancing opportunities for health professionals to make use of this evaluative tool.

    Full Text Available Paul Wouters’ essay is concerned with bridging the gap between what we value in our academic work and how we are assessed in formal evaluation exercises. He reflects on the recent evaluation of his own center, and reminds us that it is productive to see evaluations not as the (obviously impossible attempt to produce a true representation of past work, but rather as the exploration and performance of “who one wants to be.” Reflecting on why STS should do more than just play along to survive in the indicator game, he suggests that our field should contribute to changing its very rules. In this endeavor, the attitude and sensibilities developed in our field may be more important than any specific theoretical concepts or methodologies.

    The New Brunswick Laboratory (NBL) is programmatically responsible to the U.S. Department of Energy (DOE) Office of Safeguards and Security (OSS) for providing independent review and evaluation of accountability measurement technology in DOE nuclear facilities. This function is addressed in part through the NBL Safegaurds Measurement Evaluation (SME) Program. The SME Program utilizes both on-site review of measurement methods along with material-specific measurement evaluation studies to provide information concerning the adequacy of subject accountability measurements. This paper reviews SME Program activities for the 1986-87 time period, with emphasis on noted improvements in measurement capabilities. Continued evolution of the SME Program to respond to changing safeguards concerns is discussed

    Appropriate discounting rules in economic evaluations have received considerable attention in the literature and in national guidelines for economic evaluations. Rightfully so, as discounting can be quite influential on the outcomes of economic evaluations. The most prominent controversies regarding discounting involve the basis for and height of the discount rate, whether costs and effects should be discounted at the same rate, and whether discount rates should decline or stay constant over time. Moreover, the choice for discount rules depends on the decision context one adopts as the most relevant. In this article, we review these issues and debates, and describe and discuss the current discounting recommendations of the countries publishing their national guidelines. We finish the article by proposing a research agenda.

    This document, which is the first evaluation report from the French National Evaluation Commission about research on radioactive waste management, was sent to the French Government on June 30, 1995. The Commission was created in January 1994 and started its investigations on April 1994. The evaluation concerns the three axes of the 91-1381 law from December 30, 1991 (1 - separation-transmutation and minimization of wastes, 2 - underground disposal, 3 - choices for conditioning, storage and disposal). The document has been written after hearing of the principal French research organisms. The report focusses on the necessity for a scientific and technical coordination between all the organisms concerned, for a consistent and open analysis of all research topics. This implies a compatibility between schedules and specifications, and with the 15 years allowed by the law. (J.S.). 15 figs., 14 tabs., 4 annexes., 1 glossary

  18. End User Evaluations

    Jay, Caroline; Lunn, Darren; Michailidou, Eleni

    As new technologies emerge, and Web sites become increasingly sophisticated, ensuring they remain accessible to disabled and small-screen users is a major challenge. While guidelines and automated evaluation tools are useful for informing some aspects of Web site design, numerous studies have demonstrated that they provide no guarantee that the site is genuinely accessible. The only reliable way to evaluate the accessibility of a site is to study the intended users interacting with it. This chapter outlines the processes that can be used throughout the design life cycle to ensure Web accessibility, describing their strengths and weaknesses, and discussing the practical and ethical considerations that they entail. The chapter also considers an important emerging trend in user evaluations: combining data from studies of “standard” Web use with data describing existing accessibility issues, to drive accessibility solutions forward.

    Scientific achievement by publishing a scientific manuscript in a peer reviewed biomedical journal is an important ingredient of research along with a career-enhancing advantages and significant amount of personal satisfaction. The road to evaluate science (research, scientific publications) among scientists often seems complicated. Scientist's career is generally summarized by the number of publications / citations, teaching the undergraduate, graduate and post-doctoral students, writing or reviewing grants and papers, preparing for and organizing meetings, participating in collaborations and conferences, advising colleagues, and serving on editorial boards of scientific journals. Scientists have been sizing up their colleagues since science began. Scientometricians have invented a wide variety of algorithms called science metrics to evaluate science. Many of the science metrics are even unknown to the everyday scientist. Unfortunately, there is no all-in-one metric. Each of them has its own strength, limitation and scope. Some of them are mistakenly applied to evaluate individuals, and each is surrounded by a cloud of variants designed to help them apply across different scientific fields or different career stages [1]. A suitable indicator should be chosen by considering the purpose of the evaluation, and how the results will be used. Scientific Evaluation assists us in: computing the research performance, comparison with peers, forecasting the growth, identifying the excellence in research, citation ranking, finding the influence of research, measuring the productivity, making policy decisions, securing funds for research and spotting trends. Key concepts in science metrics are output and impact. Evaluation of science is traditionally expressed in terms of citation counts. Although most of the science metrics are based on citation counts but two most commonly used are impact factor [2] and h-index [3].

  20. Noninvasive Urodynamic Evaluation

    Directory of Open Access Journals (Sweden)

    Carlos Arturo Levi D'Ancona

    2012-09-01

    Full Text Available The longevity of the world's population is increasing, and among male patients, complaints of lower urinary tract symptoms (LUTS are growing. Testing to diagnose LUTS and to differentiate between the various causes should be quick, easy, cheap, specific, not too bothersome for the patient, and noninvasive or minimally so. Urodynamic evaluation is the gold standard for diagnosing bladder outlet obstruction (BOO but presents some inconveniences such as embarrassment, pain, and dysuria; furthermore, 19% of cases experience urinary retention, macroscopic hematuria, or urinary tract infection. A greater number of resources in the diagnostic armamentarium could increase the opportunity for selecting less invasive tests. A number of groups have risen to this challenge and have formulated and developed ideas and technologies to improve noninvasive methods to diagnosis BOO. These techniques start with flowmetry, an increase in the interest of ultrasound, and finally the performance of urodynamic evaluation without a urethral catheter. Flowmetry is not sufficient for confirming a diagnosis of BOO. Ultrasound of the prostate and the bladder can help to assess BOO noninvasively in all men and can be useful for evaluating the value of BOO at assessment and during treatment of benign prostatic hyperplasia patients in the future. The great advantages of noninvasive urodynamics are as follows: minimal discomfort, minimal risk of urinary tract infection, and low cost. This method can be repeated many times, permitting the evaluation of obstruction during clinical treatment. A urethral connector should be used to diagnose BOO, in evaluation for surgery, and in screening for treatment. In the future, noninvasive urodynamics can be used to identify patients with BOO to initiate early medical treatment and evaluate the results. This approach permits the possibility of performing surgery before detrusor damage occurs.

    Dysphagia is a common complaint in patients presenting for radiological or endoscopic examination of the esophagus and is usually due to functional or structural abnormalities of the esophageal body or esophagogastric region. The authors review the radiological evaluation of the esophagus and esophagogastric region in patients with esophageal dysphagia and discuss the roentgenographic techniques used, radiological efficacy for common structural disorders, and evaluation of esophageal motor function. Comparison is made with endoscopy in assessing dysphagia, with the conclusion that the radiological examination be used initially in patients with this complaint.

    Most methodologies of evaluation currently used are based upon the theory of statistical inference. It is generally perceived that this theory is not capable of dealing satisfactorily with what are called systematic errors. Theories of logical inference should be capable of treating all of the information available, including that not involving frequency data. A theory of logical inference is presented as an extension of deductive logic via the concept of plausibility and the application of group theory. Some conclusions, based upon the application of this theory to evaluation of data, are also given

    Risk assessment involves subjectivity, which makes objective decision making difficult in the nuclear power debate. The author reviews the process and uncertainties of estimating risks as well as the potential for misinterpretation and misuse. Risk data from a variety of aspects cannot be summed because the significance of different risks is not comparable. A method for including political, social, moral, psychological, and economic factors, environmental impacts, catastrophes, and benefits in the evaluation process could involve a broad base of lay and technical consultants, who would explain and argue their evaluation positions. 15 references.

    The first phase of an evaluation of the new AS/A-level course Advancing Physics, sponsored by the Institute of Physics, is now complete. It shows that the course has achieved very high satisfaction ratings from teachers of the course, and that a majority of these teachers see it as achieving its main aims. The first phase of the evaluation was designed to pinpoint aspects of Advancing Physics that offer scope for improvement. Two such aspects have been identified: course planning and use of the CD-ROM material, and arrangements for coursework in the examination.

    2012-12-01

    Integrated assessment models of climate change (IAMs) are widely used to provide insights into the dynamics of the coupled human and socio-economic system, including emission mitigation analysis and the generation of future emission scenarios. Similar to the climate modeling community, the integrated assessment community has a two decade history of model inter-comparison, which has served as one of the primary venues for model evaluation and confirmation. While analysis of historical trends in the socio-economic system has long played a key role in diagnostics of future scenarios from IAMs, formal hindcast experiments are just now being contemplated as evaluation exercises. Some initial thoughts on setting up such IAM evaluation experiments are discussed. Socio-economic systems do not follow strict physical laws, which means that evaluation needs to take place in a context, unlike that of physical system models, in which there are few fixed, unchanging relationships. Of course strict validation of even earth system models is not possible (Oreskes etal 2004), a fact borne out by the inability of models to constrain the climate sensitivity. Energy-system models have also been grappling with some of the same questions over the last quarter century. For example, one of "the many questions in the energy field that are waiting for answers in the next 20 years" identified by Hans Landsberg in 1985 was "Will the price of oil resume its upward movement?" Of course we are still asking this question today. While, arguably, even fewer constraints apply to socio-economic systems, numerous historical trends and patterns have been identified, although often only in broad terms, that are used to guide the development of model components, parameter ranges, and scenario assumptions. IAM evaluation exercises are expected to provide useful information for interpreting model results and improving model behavior. A key step is the recognition of model boundaries, that is, what is inside

  17. Radionuclide calibrators performance evaluation

    Mora Ramirez, E.; Zeledon Fonseca, P.; Jimenez Cordero, M.

    2008-01-01

    Radionuclide calibrators are used to estimate accurately activity prior to administration to a patient, so it is very important that this equipment meets its performance requirements. The purpose of this paper is to compare the commercially available 'Calicheck' (Calcorp. Inc), used to assess linearity, versus the well-known source decay method, and also to show our results after performing several recommended quality control tests. The parameters that we wanted to evaluate were carried on using the Capintec CRC-15R and CRC-15 β radionuclide calibrators. The evaluated tests were: high voltage, display, zero adjust, background, reproducibility, source constancy, accuracy, precision and linearity. The first six tests were evaluated on the daily practice, here we analyzed the 2007 recorded data; and the last three were evaluated once a year. During the daily evaluation both calibrators performance were satisfactory comparing with the manufacture's requirements. The accuracy test show result within the ± 10% allowed for a field instrument. Precision performance is within the ± 1 % allowed. On the other hand, the linearity test shows that using the source decay method the relative coefficient is 0.9998, for both equipment and using the Calicheck the relative coefficient is 0.997. However, looking the percentage of error, during the 'Calicheck' test, its range goes from 0.0 % up to -25.35%, and using the source decay method, the range goes from 0.0 % up to -31.05 %, taking into account both instruments. Checking the 'Calicheck' results we can see that the results varying randomly, but using the source decay method the percentage of error increase as the source activity decrease. We conclude that both devices meet its manufactures requirements, in the case of the linearity using the decay method, decreasing the activity source, increasing the percentage of error, this may happen because of the equipment age.

    2015-09-01

    Full Text Available This paper deals with the evaluation of selected available indicators of living standards, divided into three groups, namely economic, environmental, and social. We have selected six countries of the European Union for analysis: Bulgaria, the Czech Republic, Hungary, Luxembourg, France, and Great Britain. The aim of this paper is to evaluate indicators measuring living standards and suggest the most important factors which should be included in the final measurement. We have tried to determine what factors influence each indicator and what factors affect living standards. We have chosen regression analysis as our main method. From the study of factors, we can deduce their impact on living standards, and thus the value of indicators of living standards. Indicators with a high degree of reliability include the following factors: size and density of population, health care and spending on education. Emissions of carbon dioxide in the atmosphere also have a certain lower degree of reliability.

    1975-09-01

    An economic analysis on oil or gas property is generally accompanied by a reservoir analysis which predicts the reserves and the performance of the reservoir, recommends the optimum economic method with which to recover the reserves, and through a performance prediction indicates a time schedule for future investments and income. The requirements for a reservoir evaluation are as follows: (1) good reservoir data; (2) oil in place; (3) reservoir energy, both primary and secondary; and (4) reserve calculation and performance predictions for giving both production schedule and selection of secondary recovery mechanisms. Given the above reservoir evaluation parameters, the following are requirements for a complete economic analysis: (1) lease exploration and purchase costs; (2) capital investments schedule dependent upon a reservoir performance prediction; and (3) factors affecting net income such as anticipated selling price of oil and gas and the availability of a market, operating costs and working interest, royalty schedule, depreciation methods, depletion methods and tax schedule.

    My summer project evaluates the Kinect game sensor input/output and its suitability to perform as part of a human interface for a spacecraft application. The primary objective is to evaluate, understand, and communicate the Kinect system's ability to sense and track fine (human) position and motion. The project will analyze the performance characteristics and capabilities of this game system hardware and its applicability for gross and fine motion tracking. The software development kit for the Kinect was also investigated and some experimentation has begun to understand its development environment. To better understand the software development of the Kinect game sensor, research in hacking communities has brought a better understanding of the potential for a wide range of personal computer (PC) application development. The project also entails the disassembly of the Kinect game sensor. This analysis would involve disassembling a sensor, photographing it, and identifying components and describing its operation.

    This paper criticizes the quick system proposed by Henk Moll for evaluating microfinance projects in the article ¿How to Pre-Evaluate Credit Projects in Ten Minutes¿. The author contended that there is a need to emphasize the objectives of the project. The procedure used by Moll, he contended, is applicable only to projects that have only two key objectives, such as credit operations, and the provision of services. Arguments are presented on the three specific questions proposed by Moll, ranging from the availability of externally audited financial reports, the performance of interest rate on loans vis-a-vis the inflation rate, and the provision of loans according to the individual requirements of the borrowers. Lastly, the author emphasizes that the overall approach is not useful and suggests that careful considerations should be observed in the use or abuse of a simple scoring system or checklist such as the one proposed by Moll.

    International Nuclear Information System (INIS)

    Hardwick, R.J. Jr.

    1985-01-01

    Operating nuclear power plants requires high standards of performance, extensive training and responsive management. Despite our best efforts inappropriate human actions do occur, but they can be managed. An extensive review of License Event Reports (LERs) was conducted which indicated continual inadequacy in human performance and in evaluation of root causes. Of some 31,000 LERs, about 5,000 or 16% were directly attributable to inappropriate actions. A recent analysis of 87 Significant Event Reports (issued by INPO in 1983) identified inappropriate actions as being the most frequent root cause (44% of the total). A more recent analysis of SERs issued in 1983 and 1984 indicate that 52% of the root causes were attributed to human performance. The Human Performance Evaluation System (HPES) is a comprehensive, coordinated utility/industry system for evaluating and reporting human performance situtations. HPES is a result of the realization that current reporting system provide limited treatment of human performance and rarely provide adequate information about root causes of inappropriate actions by individuals. The HPES was implemented to identify and eliminate root causes of inappropriate actions

  18. Critical heat flux evaluation

    International Nuclear Information System (INIS)

    Banner, D.

    1995-01-01

    Critical heat flux (CHF) is of importance for nuclear safety and represents the major limiting factors for reactor cores. Critical heat flux is caused by a sharp reduction in the heat transfer coefficient located at the outer surface of fuel rods. Safety requires that this phenomenon also called the boiling crisis should be precluded under nominal or incidental conditions (Class I and II events). CHF evaluation in reactor cores is basically a two-step approach. Fuel assemblies are first tested in experimental loops in order to determine CHF limits under various flow conditions. Then, core thermal-hydraulic calculations are performed for safety evaluation. The paper will go into more details about the boiling crisis in order to pinpoint complexity and lack of fundamental understanding in many areas. Experimental test sections needed to collect data over wide thermal-hydraulic and geometric ranges are described CHF safety margin evaluation in reactors cores is discussed by presenting how uncertainties are mentioned. From basic considerations to current concerns, the following topics are discussed; knowledge of the boiling crisis, CHF predictors, and advances thermal-hydraulic codes. (authors). 15 refs., 4 figs

    The purpose of this analysis is to evaluate impacts to the retrieval concept presented in the Design Analysis ''Retrieval Equipment and Strategy'' (Reference 6), from abnormal events based on Design Basis Events (DBE) and Beyond Design Basis Events (BDBE) as defined in two recent analyses: (1) DBE/Scenario Analysis for Preclosure Repository Subsurface Facilities (Reference 4); and (2) Preliminary Preclosure Design Basis Event Calculations for the Monitored Geologic Repository (Reference 5) The objective of this task is to determine what impacts the DBEs and BDBEs have on the equipment developed for retrieval. The analysis lists potential impacts and recommends changes to be analyzed in subsequent design analyses for developed equipment, or recommend where additional equipment may be needed, to allow retrieval to be performed in all DBE or BDBE situations. This analysis supports License Application design and therefore complies with the requirements of Systems Description Document input criteria comparison as presented in Section 7, Conclusions. In addition, the analysis discusses the impacts associated with not using concrete inverts in the emplacement drifts. The ''Retrieval Equipment and Strategy'' analysis was based on a concrete invert configuration in the emplacement drift. The scope of the analysis, as presented in ''Development Plan for Retrieval Events Evaluation'' (Reference 3) includes evaluation and criteria of the following: Impacts to retrieval from the emplacement drift based on DBE/BDBEs, and changes to the invert configuration for the preclosure period. Impacts to retrieval from the main drifts based on DBE/BDBEs for the preclosure period

    Objective: To find out the relative frequency of clinical conditions associated with splenomegaly that require hematological evaluation in our set up. Subjects and Methods: Patients of either gender or all age groups with palpable spleen was included. Patients with splenomegaly due to liver disease, malarial parasites on thick or thin blood film, positive Widal test, or positive blood cultures were excluded from study. Patients were initially evaluated with clinical history, microscopic examination of blood smear, and blood counts. Depending upon provisional diagnosis bone marrow examination or investigations for hemolytic anemia were performed. Results: One hundred patients were received. Seventy-eight patients were adults and 22 patients were of pediatric age group. In the adults, hematological malignancies were seen in 37%, malarial parasites in bone marrow in 20.5%, megaloblastic anemia in 13%, bacterial infections in 9%, hemolytic anemia in 9%, tropical splenomegaly in 5%, and positive bone marrow culture for salmonella in 6.5%. In children, hematological evaluation revealed hematological malignancies in 18%, beta thalassaemia in 55%, other hemolytic anemias in 13.5%, congenital sideroblastic anemia in 4.5%, and storage disorder in 9%. Conclusion: Hematological workup is informative in most of the cases. Bone marrow examination is the key investigation, hematological malignancies constituted 37% of the adult and 18% of pediatric age group patients. Hemolytic anemia constituted 68% of pediatric age group. (author)

    The United States high-level waste program requires evaluation of radiological safety during two distinct time intervals. The first interval, commonly referred to as the preclosure period, deals with receipt of waste at the site, transfer into disposal containers, if needed, emplacement in the underground openings, monitoring and maintenance activities, backfill and closure of the underground openings, and decontamination and decommissioning of the surface facilities of the geologic repository. The preclosure period may extend from a few tens of years to as long as a few hundred of years, depending on repository design and societal norms regarding a final decision to permanently seal the repository. During the preclosure or operational period, performance confirmation studies are conducted to provide a basis for updating and reevaluating estimates of postclosure performance and, finally, to provide a basis for a closure decision. The postclosure period during which expected repository performance must meet certain standards may range from ten thousands years, as it does in the United States, to millions of years, as it does in some European nations. Waste handling operations in the preclosure period are to be evaluated in relation to their potential effect on workers, members of general public, and the general environment. During this period, releases of radioactivity are to be monitored and appropriate actions taken whenever established limits are approached or exceeded. Preclosure safety is highly dependent on facility design, operational hardware and automated systems, operational sequences, and reliability of humans involved in operations. Preclosure safety analyses conducted before operations begin play a major role in the design process, selection of equipment, and development of operational procedures. Because of the complexity, duration, and spatial scales of the operations, analyses are conducted using mathematical models implemented in computer codes

  5. Modern evaluation of patents

    Science.gov (United States)

    Ignat, V.

    2016-08-01

    The number of patents is not so important as the market value. The market value is especially important for licensing of patents, make-or-buy decisions for technology procurement, corporate finance. Patents can be used as collateral for financing. Patents and credit approvals: without patents only 46% and with patents 54%. The value share of knowledge-based components to industrial products already reached 50% and it is still rising. OECD called these developments under the slogan "knowledge economy”. German Norm-DIN 77100 provides a working method for monetary evaluation of a patent. The value of a patent arises from its use. A patent can be used to protect or to earn licensing revenues. An evaluation expertise is required in areas, such as marketing, finance, R & D and strategic planning. As an indicator of the value of a patent is often used the number of citations. The number of a patent citation refers to its meaning and value. Other indicators would be: size of the patent family, validity of the patent, result of objections against patent application, number and quality of claims. The analysis of 9.000 patents resulted that only 7.2% worth over 10 million euro and 68% below 1 million euro. The cost method: it is considered the cost that would be incurred for the development and patenting of a similar invention. The market method: are used the prices that have been achieved in comparable with recently transactions. The Income method: the potential reward is measured, which can arise from a patent. The evaluation will be in the following areas: legal status, technology, market conditions, finance and strategy. Each question relates to a different parameter of a value.

    To define variables for the evaluation of keratoconus progression and to determine cut-off values. In this retrospective cohort study (2010-2016), 265 eyes of 165 patients diagnosed with keratoconus underwent two Scheimpflug measurements (Pentacam) that took place 1 year apart ±3 months. Variables used for keratoconus detection were evaluated for progression and a correlation analysis was performed. By logistic regression analysis, a keratoconus progression index (KPI) was defined. Receiver-operating characteristic curve (ROC) analysis was performed and Youden Index calculated to determine cut-off values. Variables used for keratoconus detection showed a weak correlation with each other (eg, correlation r=0.245 between RPImin and Kmax, pKPI). KPI was defined by logistic regression and consisted of a Pachymin coefficient of -0.78 (p=0.001), a maximum elevation of back surface coefficient of 0.27 and coefficient of corneal curvature at the zone 3 mm away from the thinnest point on the posterior corneal surface of -12.44 (both pKPI: D-index had a cut-off of 0.4175 (70.6% sensitivity) and Youden Index of 0.606. Cut-off for KPI was -0.78196 (84.7% sensitivity) and a Youden Index of 0.747; both 90% specificity. Keratoconus progression should be defined by evaluating parameters that consider several corneal changes; we suggest D-index and KPI to detect progression. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Surgeons, orthopedic surgeons, and neurosurgeons employ a wide variety of different osteosynthetic devices in the treatment of fractures and in spinal surgery. In order to assess these instruments correctly, the radiologist should be aware of their purpose and normal apperance. The complications should be identified, such as delayed union, pseudarthrosis, dislocation, device loosening, fracture of the device, osteomyelitis, and refracture. To evaluate the fixation device adequately two plain radiographs are mandatory. An normal fracture healing and the most commonly used fixation devices, the abnormalities of fracture healing and their complications are discussed. (orig.) [de

    The detection of the unauthorized movement of radioactive materials is one of the most effective nonproliferation measures. Automatic special nuclear material (SNM) portal monitors are designed to detect this unauthorized movement and are an important part of the safeguard systems at US nuclear facilities. SNM portals differ from contamination monitors because they are designed to have high sensitivity for the low energy gamma-rays associated with highly enriched uranium (HEU) and plutonium. These instruments are now being installed at international borders to prevent the spread of radioactive contamination an SNM. In this paper the parameters important to evaluating radiation portal monitors are discussed. (author)

    RAPIDC is a programme contributing to solving air pollution in South Asia and Southern Africa. Our evaluation of RAPIDC shows that the programme is mainly on schedule and is producing technical results of high quality. It is also contributing significantly to cooperation on and understanding of air pollution problems in South Asia and Southern Africa. RAPIDC has so far been weak on mitigation and policy analysis, and lacks a targeted information strategy to effectively promote policy interventions in the countries. Actions should be taken to reduce these shortcomings for the rest of phase III and an eventual phase IV

    The performance of an apparatus for measuring continuously the sulfur content of coal entering a 3000-MW electric generating power station is described. The apparatus, known as a Sulfurmeter, interrogates a sidestream of coal in a nondestructive fashion using prompt neutron activation analysis (PNAA). Preceding the Sulfurmeter is a coal-handling facility that blends a 1% S coal with a 3% S coal. The Sulfurmeter is used to evaluate the blend, which must meet an emission standard of 3.68 lb of SO 2 /10 6 Btu when fired. Sulfur measurements by the PNAA apparatus were compared with those from traditional ASTM chemistry - satisfactory agreement was obtained

Today, the algorithms for shadow and check computation are specific for every pointcut designator. This makes it very tedious to extend the pointcut language. We propose the use of declarative languages, together with associated analysis and specialisation tools, to implement powerful and extensible...

    Full Text Available Studies have shown that vascular impairment plays an important role in the etiology and pathogenesis of various ocular diseases including glaucoma, age-related macular degeneration, diabetic retinopathy, and retinal venous occlusive disease. Thus, qualitative and quantitative assessment of ocular blood flow (BF is a topic of interest for early disease detection, diagnosis, and management. Owing to the rapid improvement in technology, there are several invasive and noninvasive techniques available for evaluating ocular BF, with each of these techniques having their own limitations and advantages. This article reviews these important techniques, with a particular focus on Doppler Fourier domain optical coherence tomography (OCT and OCT-angiography.

    The purpose of the ANL MPACT Voltammetry project is to evaluate the suitability of previously developed cyclic voltammetry techniques to provide electroanalytical measurements of actinide concentrations in realistic used fuel processing scenarios. The molten salts in these scenarios are very challenging as they include high concentrations of multiple electrochemically active species, thereby creating a variety of complications. Some of the problems that arise therein include issues related to uncompensated resistance, cylindrical diffusion, and alloying of the electrodeposited metals. Improvements to the existing voltammetry technique to account for these issues have been implemented, resulting in good measurements of actinide concentrations across a wide range of adverse conditions.

    1973-08-01

    A short discussion is given of the physics of a nuclear reactor and the parameters which are used in the study of neutron transport. The mathematical formulation and detailed derivation is given of the neutron diffusion and transport equations. A description is given of the computer programmes, FIRE-5 and PELSN, developed at Pelindaba for the evaluation of both thermal and fast reactor systems. It is indicated how these computer programmes have been applied in the study of the PELINDUNA-O and other known critical facilities. The application of Lie-series to the solution of the neutron diffusion equation is discussed in detail. The time dependence of the variables is removed by means of a Laplacetransformation and the semi-analytical solution is written in terms of a transfer matrix. A complete set of recursion formulae, applicable to both homogeneous and heterogeneous reactor systems, is derived. The method used in the evaluation of the effective multiplication factor, k-eff, and the alpha-eigen-value is described. A computer programme was written to solve the neutron diffusion equation in terms of the Lie-series. The results are compared with the TIMOC and PELSN computer programmes. A method is suggested in which the Lie-series are used to solve the neutron transport equation. The transfer matrix for this case, is derived. A complete discussion is given of the solution to the space and time dependent diffusion equation in the presence of a delta source [af

  6. Evaluation of stigmatized properties

    Directory of Open Access Journals (Sweden)

    Hajnal István

    2017-12-01

    Full Text Available Stigmatized property is real estate burdened with an external negative effect. Individual cases are spread along a broad spectrum, along many dimensions that include the rational and the irrational, the acute and the chronic. Examples for the stigmatizing effect are a nearby airport, ground water contaminated by chemicals, presence of a high-voltage power line, and so on. Eval­uation of these properties needs special methodology. Stigma can reduce the property’s market value through a particular, multi-layered filter. The author systematically examines the professional literature’s cases of evaluation of stigmatized properties. The research aims to organize and compare the cases in order to calculate the market value of stigmatized properties. Based on the analysis, six significant dimensions are identified. A focus group of 19 experts examined and individually evaluated the stigma­tizing effects along these different dimensions. The author suggests that it is possible to estimate the stigma’s effect and compare different cases to one another effectively. The results allow the international methodology of valu­ation to be processed.

  7. Thyroid evaluation with radioassay

    International Nuclear Information System (INIS)

    Ashkar, F.S.

    1983-01-01

    Thyroid hormone is given therapeutically for the treatment of hypothyroidism and in goiterous conditions. When administered in full maintenance dosage, it interrupts the operation of the homeostatic mechanism that evokes excesses of thyrotropin (TSH) in response to various goiterogenic stimuli or impending thyroid failure, resulting in thyroid gland enlargement. All patients with treated thyroid cancer are maintained indefinitely on full replacement dosages of thyroid hormone to eliminate endogenous TSH and its trophic effect, thereby minimizing recurrence and growth of the tumor. A high-risk group of patients that were irradiated to the head and neck in childhood for various reasons are placed on thyroid hormone therapy prophylactically to turn off their endogenous TSH if they are found free of thyroid nodularity on initial evaluation. The adequacy of thyroid hormone therapy and the regularity of its intake can be ultimately evaluated by the thyrotropin releasing hormone (TRH) stimulation test, where no TSH response indicates adequate therapy and a normal TSH response suggests inadequate or irregular treatment

  8. Evaluating imaging devices

    International Nuclear Information System (INIS)

    Rollo, F.D.

    1977-01-01

    The performance of any imaging device depends on two principal factors inherent to the device, namely, plane sensitivity and spatial resolution. These factors may be defined as follows: plane sensitivity is the counts per second recorded by the imaging device for each disintegration per second per square centimeter occurring within a plane sheet of radioactivity. Spatial resolution may be defined as the fidelity with which the imaging device reproduces the activity distribution of an object in the image plane. In all imaging devices, a trade-off exists between these two parameters; that is, as sensitivity improves, spatial resolution is degraded, and vice versa. Therefore, to fully evaluate an imaging system a technique should be selected that measures both parameters and reflects the trade-off between the two. In addition, the method should approximate the clinical problem, namely, the detection of a focal lesion within an activity distribution. Several methods have been described to evaluate nuclear imaging devices. The more common techniques include the use of organ phantoms, bar phantoms, line-spread functions, modulation transfer functions, contrast efficiency functions, and performance index functions. Each of these techniques is briefly described in this chapter, and their advantages and disadvantages are discussed. In addition, a phantom that can be used to simply and completely measure overall imaging system performance is described

    In recent years, several research groups have developed automatic algorithms to detect diabetic retinopathy (DR) in individuals with diabetes (DM), using digital retinal images. Studies have indicated that diabetics have 1.5 times the annual risk of developing primary open angle glaucoma (POAG) as do people without DM. Moreover, DM patients have 1.8 times the risk for age-related macular degeneration (AMD). Although numerous investigators are developing automatic DR detection algorithms, there have been few successful efforts to create an automatic algorithm that can detect other ocular diseases, such as POAG and AMD. Consequently, our aim in the current study was to develop a comprehensive eye evaluation algorithm that not only detects DR in retinal images, but also automatically identifies glaucoma suspects and AMD by integrating other personal medical information with the retinal features. The proposed system is fully automatic and provides the likelihood of each of the three eye disease. The system was evaluated in two datasets of 104 and 88 diabetic cases. For each eye, we used two non-mydriatic digital color fundus photographs (macula and optic disc centered) and, when available, information about age, duration of diabetes, cataracts, hypertension, gender, and laboratory data. Our results show that the combination of multimodal features can increase the AUC by up to 5%, 7%, and 8% in the detection of AMD, DR, and glaucoma respectively. Marked improvement was achieved when laboratory results were combined with retinal image features.

  10. EVALUATING COMMERCIALLY AVAILABLE DERMAL ...

    Science.gov (United States)

    As the Human Exposure Program focuses on the exposure of children to pesticides, there are concerns about the effect, or perceived effect, of components of the sampling procedure on the health and well-being of the infant and the ability to collect pesticide residues. One concern involves the materials in wipes used to collect pesticide residues or other contact materials on the skin. In recent studies (e.g., National Human Exposure Assessment Survey; NHEXAS), isopropyl alcohol has been used as a solvent in conjunction with a cloth wipe to obtain samples from the hands of adults and children. Although isopropyl alcohol is generally considered innocuous, the use of commercially available products could eliminate concerns about exposure to alcohol. A few studies have evaluated the potential of commercially available baby wipes to collect personal exposure samples for metals research, but not for the area of pesticide research (Millson et al., 1994; Campbell et al., 1993; Lichtenwalner et al., 1993). Therefore, there is a need to evaluate the potential for using commercially available baby wipes for collecting pesticide samples from skin and other surfaces. Another concern involves establishing a convenient and safe method for assessing overall dermal exposure for children, especially for those in crawling stage. One route that the U .S. Environmental Protection Agency (EPA) would like to investigate is the use of cotton body suits (infant sleepers) as an indicator

    The U.S. Department of Energy (DOE) is responsible for the final disposition of legacy spent nuclear fuel (SNF). As a response, DOE's National Spent Nuclear Fuel Program (NSNFP) has been given the responsibility for the disposition of DOE-owned SNF. Many treatment technologies have been identified to treat some forms of SNF so that the resulting treated product is acceptable by the disposition site. One of these promising treatment processes is the electrometallurgical treatment (EMT) currently in development; a second is an Acid Wash Decladding process. The NSNFP has been tasked with identifying possible strategies for the deployment of these treatment processes in the event that a treatment path is deemed necessary. To support the siting studies of these strategies, economic evaluations are being performed to identify the least-cost deployment path. This model (tool) was developed to consider the full scope of costs, technical feasibility, process material disposition, and schedule attributes over the life of each deployment alternative. Using standard personal computer (PC) software, the model was developed as a comprehensive technology economic assessment tool using a Life-Cycle Cost (LCC) analysis methodology. Model development was planned as a systematic, iterative process of identifying and bounding the required activities to dispose of SNF. To support the evaluation process, activities are decomposed into lower level, easier to estimate activities. Sensitivity studies can then be performed on these activities, defining cost issues and testing results against the originally stated problem

    Risk analysis and performance evaluation methodology were applied to the aging evaluation of active components in the periodic safety review of Wolsung unit 1. We conclude that evaluation of performance is more effective to discriminate the aging degradation of active component than the evaluation of aging mechanism. It is essential to analyze the common cause failures of low performance components to evaluate the properness of present maintenance system. Past 10 years failure history is used for establishing the performance criteria. Past 2 years failure history is used for the evaluating the recent performance condition. We analyze the failure mode of the components to improve the maintenance system. Performance evaluation methodology is useful for the quantitative evaluation of aging degradation of active components. Analysis on the repeated failures can be useful for the feedback to maintenance plan and interval

    Full Text Available Introduction. Chronic diseasesare the leading cause of population mortality worldwide. They have reached alarming proportions. This is linked to the epidemiological transition that has changed the health picture dominated by infectious diseases, by the progressive disappearance of infectious diseases and the proliferation of chronic diseases. This phenomenon has not spared Algeria, where diabetes is one of the major problems of public health. Studies have revealed a female predominance of diabetes around the world and nationally, as well as a greater number of deaths. On the contrary, a low interest was observed for this gender characteristic. In addition to the medicinal treatment prescribed for diabetes, dietetic measures are recommended, where emphasis was placed on the importance of nutritional intake in maintaining the glycemic balance.Objective. In this context, we undertook a socio-anthropological study with the main objective of shedding light on the complexity of these food practices. Methodology. We have mobilized a qualitative approach based on twenty interviews, conducted at home, with diabetic patients living in Oran. .Résults The influence of social gender relationships was noted on the dietary practices of diabetic women.The criteria of taste appreciation, pleasure of eating, and sense of sharing were highlighted in the choice of foods. Eating habits appeared as very strong identity markers, imbued with culinary traditions. Conclusion. This brings us to the importance of a socio-anthropological approach to diet in patients with diabetes.

    Full Text Available Drawing on Julia Kristeva's amorous dialogue with Therese in Therese, mon amour, her third volume on the powers and limits of psychoanalysis (La haine et le pardon, and Cet incroyable besoin de croire, my aim in this essay is to unpack Kristeva's theory of sublimation which, I suggest, Therese helps her elaborate, enrich and complicate. In particular, I focus on Kristeva's foregrounding of the mediating role of language in the sublimatory process and her rethinking of the experience and stakes of sublimation in light of what has been discussed as the central problematic of the baroque: namely, the blurring of the distinction between appearance and reality and the uninhibited celebration of illusion. As I demonstrate, this problematic and Therese's unique response to it are most important for Kristeva since they enable her to raise questions which carry her beyond her previous treatments of sublimation. These questions relate to the amorous source of the imaginary; the dynamic established between idealization and sublimation; the dangers of an unbridled imaginary; the uncomfortable residue of matter and the body; the dialectic between finitude and infinity, unity and multiplicity.

    The hypoxia response regulated primarily by hypoxia-inducible factor (HIF) influences metabolism, cell survival, and angiogenesis to maintain biological homeostasis. In addition to the traditional transcriptional regulation by HIF, recent studies have shown that epigenetic modulation such as histone methylation, acetylation, and DNA methylation could change the regulation of the response to hypoxia. Eukaryotic chromatin is known to be modified by multiple post-translational histone methylation and demethylation, which result in the chromatin conformation change to adapt to hypoxic stimuli. Interestingly, some of the histone demethylase enzymes, which have the Jumonji domain-containing family, require oxygen to function and are induced by hypoxia in an HIF-1-dependent manner. Recent studies have demonstrated that histone modifiers play important roles in the hypoxic environment such as that in cancer cells and that they may become new therapeutic targets for cancer patients. It may lead to finding a new therapy for cancer to clarify a new epigenetic mechanism by HIF and histone demethylase such as JMJD1A (KDM3A) under hypoxia.

    Full Text Available Pig farms: reservoirs of vectors of Bluetongue and Schmallenberg viruses?. Bluetongue (BT is a vector-borne disease that affects domestic and wild ruminants. Since its recent outbreak in northern Europe, this viral disease has caused considerable economic losses. The biological vectors of the bluetongue virus are biting midges belonging to the genus Culicoides (Diptera: Ceratopogonidae. Several light trapping campaigns targeting these adult midges have been previously conducted in Belgium within cattle and sheep farms, but none have been performed inside pig farms. This study therefore aims to assess, using light traps, the levels of Culicoides populations that may have been present inside two Belgian pig farms during the fall and winter of 2008. The presence of (potential Culicoides vector species was demonstrated inside the pig buildings during the fall: 8 and 749 specimens belonging to 2 and 7 species were respectively trapped inside the pigsties, with the majority being Obsoletus complex females. The opening up of the buildings seemed to strongly influence their presence. Observation of the females' nutritional status suggests that these midges were likely to have fed or to have laid eggs inside the pig farms, despite the fact that pig's blood could not be identified in the abdomen of engorged females and that pig manure did not reveal the presence of larvae. Pigs could thus be involved in the maintenance of potential vector species populations of the BT virus, or of the new Schmallenberg virus.

    Reyes-Aldasoro, Constantino Carlos

    2017-01-01

    In this work, the public database of biomedical literature PubMed was mined using queries with combinations of keywords and year restrictions. It was found that the proportion of Cancer-related entries per year in PubMed has risen from around 6% in 1950 to more than 16% in 2016. This increase is not shared by other conditions such as AIDS, Malaria, Tuberculosis, Diabetes, Cardiovascular, Stroke and Infection some of which have, on the contrary, decreased as a proportion of the total entries per year. Organ-related queries were performed to analyse the variation of some specific cancers. A series of queries related to incidence, funding, and relationship with DNA, Computing and Mathematics, were performed to test correlation between the keywords, with the hope of elucidating the cause behind the rise of Cancer in PubMed. Interestingly, the proportion of Cancer-related entries that contain "DNA", "Computational" or "Mathematical" have increased, which suggests that the impact of these scientific advances on Cancer has been stronger than in other conditions. It is important to highlight that the results obtained with the data mining approach here presented are limited to the presence or absence of the keywords on a single, yet extensive, database. Therefore, results should be observed with caution. All the data used for this work is publicly available through PubMed and the UK's Office for National Statistics. All queries and figures were generated with the software platform Matlab and the files are available as supplementary material.

  9. Pragmatic geometric model evaluation

    Pamer, Robert

    2015-04-01

    Quantification of subsurface model reliability is mathematically and technically demanding as there are many different sources of uncertainty and some of the factors can be assessed merely in a subjective way. For many practical applications in industry or risk assessment (e. g. geothermal drilling) a quantitative estimation of possible geometric variations in depth unit is preferred over relative numbers because of cost calculations for different scenarios. The talk gives an overview of several factors that affect the geometry of structural subsurface models that are based upon typical geological survey organization (GSO) data like geological maps, borehole data and conceptually driven construction of subsurface elements (e. g. fault network). Within the context of the trans-European project "GeoMol" uncertainty analysis has to be very pragmatic also because of different data rights, data policies and modelling software between the project partners. In a case study a two-step evaluation methodology for geometric subsurface model uncertainty is being developed. In a first step several models of the same volume of interest have been calculated by omitting successively more and more input data types (seismic constraints, fault network, outcrop data). The positions of the various horizon surfaces are then compared. The procedure is equivalent to comparing data of various levels of detail and therefore structural complexity. This gives a measure of the structural significance of each data set in space and as a consequence areas of geometric complexity are identified. These areas are usually very data sensitive hence geometric variability in between individual data points in these areas is higher than in areas of low structural complexity. Instead of calculating a multitude of different models by varying some input data or parameters as it is done by Monte-Carlo-simulations, the aim of the second step of the evaluation procedure (which is part of the ongoing work) is to

    Cytotoxicity testing (cell growth inhibition, LDH-assay) has shown that RVNRL materials are considerably less cytotoxic than sulphur-vulcanised materials. Also the effect of applying different leaching times during the production process was investigated and gave interesting results. Protein testing (BCA - comparable to a Lowry assay ) has shown that some, but not all proteins are destroyed during irradiation. For the total protein content of the materials as determined in this way, the effect of leaching proved to be very important. This was also checked by; SDS-PAGE assays: After irradiation a smear is observed with SDS-PAGE; when the irradiated material has been leached, most of the smear has disappeared. An important protein (14 kD) is still present and seems hardly to be affected. The materials have also been evaluated clinically, using well characterised patient sera (Western blotting) in order to determine whether the remaining proteins are allergenic

    Although the operation of nuclear reactors has a remarkably good record of safety, the prevention of possible reactor accidents is one of the major factors that atomic planners have to contend with. At the same time, excessive caution may breed an attitude that hampers progress, either by resisting new development or by demanding unnecessarily elaborate and expensive precautions out of proportion to the actual hazards involved. The best course obviously is to determine the possible dangers and adopt adequate measures for their prevention, providing of course, for a reasonable margin of error in judging the hazards and the effectiveness of the measures. The greater the expert understanding and thoroughness with which this is done, the narrower need the margin be. This is the basic idea behind the evaluation of reactor safety

    International Nuclear Information System (INIS)

    McKay, M.D.

    1995-03-01

    The probability distribution of a model prediction is presented as a proper basis for evaluating the uncertainty in a model prediction that arises from uncertainty in input values. Determination of important model inputs and subsets of inputs is made through comparison of the prediction distribution with conditional prediction probability distributions. Replicated Latin hypercube sampling and variance ratios are used in estimation of the distributions and in construction of importance indicators. The assumption of a linear relation between model output and inputs is not necessary for the indicators to be effective. A sequential methodology which includes an independent validation step is applied in two analysis applications to select subsets of input variables which are the dominant causes of uncertainty in the model predictions. Comparison with results from methods which assume linearity shows how those methods may fail. Finally, suggestions for treating structural uncertainty for submodels are presented

    The purpose of this paper is to provide a structured and cost-oriented process to determine risks associated with nuclear material and other security interests. Financial loss is a continuing concern for US Department of Energy contractors. In this paper risk is equated with uncertainty of cost impacts to material assets or human resources. The concept provides a method for assessing the effectiveness of an integrated protection system, which includes operations, safety, emergency preparedness, and safeguards and security. The concept is suitable for application to sabotage evaluations. The protection of assets is based on risk associated with cost impacts to assets and the potential for undesirable events. This will allow managers to establish protection priorities in terms of the cost and the potential for the event, given the current level of protection

These properties are melting point, normal boiling point, standard enthalpy of vaporization at 298 K, standard enthalpy of formation at 298 K, standard enthalpy of combustion at 298 K, density (specific gravity) and flash point. These methods are validated, despite the scarcity of experimental data, with several tens of polycyclic alkanes. Then the methods are used to estimate properties of some polycyclic alkanes, which are currently in use as missile fuels: JP-10, RJ-4 and RJ-5. Estimates and experimental data are found in good agreement for these fuels. This methodology is then used to evaluate missile fuel candidates to be used pure or as additive to JP-10 or to blends such as RJ-6. Several compounds are probably of interest for this task and their advantages and drawbacks are discussed. (Abstract Copyright [2006], Wiley Periodicals, Inc.)

    Full Text Available ABSTRACT However common tension-type headache is in epidemiologic population-based studies, migraine is the most common diagnosis in patients seeking treatment for headache in primary care. The appropriate evaluation of headache should be as follows: 1 To rule out the most serious underlying pathologies and to look for other secondary causes of headache, 2 To determine the type of primary headache using the patient's history as a primary diagnostic tool. Symptoms can always overlap, particularly between migraine and tension-type headache and between migraine and some secondary causes of headache (such as neurologic or systemic disease. A brief headache screen based only on anamnesis and physical examination data which direct to an underlying pathology is useful to primary care physicians in particular. An imaging study is not necessary in the vast majority of patients presenting with headache. Nevertheless, imaging (usually CT scan is warranted in the patients outlined above.

    This paper reports that the Pacific Gas and Electric Company (PG and E), in cooperation with ABZ, Incorporated and Science Applications International Corporation (SAIC), investigated the use of artificial intelligence-based programming techniques to assist utility personnel in regulatory compliance problems. The result of this investigation is that artificial intelligence-based programming techniques can successfully be applied to this problem. To demonstrate this, a general methodology was developed and several prototype systems based on this methodology were developed. The prototypes address U.S. Nuclear Regulatory Commission (NRC) event reportability requirements, technical specification compliance based on plant equipment status, and quality assurance assistance. This collection of prototype modules is named the safety significance evaluation system

    Polymer wear plays an increasing role in manufacturing of machine parts for e.g. medical devices. Some of these have an expected lifetime of five to eight years during which very little wear of the components is acceptable. Too much wear compromises the dosage accuracy of the device and thereby...... the safety of the patients. Prediction of the wear of polymers is complicated by the low thermal conductivity of this kind of material. It implies that any acceleration of testing conditions by increased contact pressure and/or sliding velocity will make the polymer fail due to exaggerated heat buildup....... This is not the kind of wear observed in medical devices. In the present work a method was developed capable of evaluating the wear progression in polymer-polymer contacts. The configuration of the setup is injection moulded specimens consisting of an upper part having a toroid shape and a lower flat part. The sliding...

    The U.S. Department of Energy's Energy Information Administration (EIA), and its predecessor organizations, has published projections of U.S. energy production, consumption, distribution and prices annually for over 30 years. A natural issue to raise in evaluating the projections is an assessment of their accuracy compared to eventual outcomes. A related issue is the determination of the sources of 'error' in the projections that are due to differences between the actual versus realized values of the associated assumptions. One way to do this would be to run the computer-based model from which the projections are derived at the time the projected values are realized, using actual rather than assumed values for model assumptions; and, compare these results to the original projections. For long term forecasts, this approach would require that the model's software and hardware configuration be archived and available for many years, possibly decades, into the future. Such archival creates many practical problems; and, in general, it is not being done. This paper reports on an alternative approach for evaluating the projections. In the alternative approach, the model is run many times for cases in which important assumptions are changed individually and in combinations. A database is assembled from the solutions and a regression analysis is conducted for each important projected variable with the associated assumptions chosen as exogenous variables. When actual data are eventually available, the regression results are then used to estimate the sources of the differences in the projections of the endogenous variables compared to their eventual outcomes. The results presented here are for residential and commercial sector natural gas and electricity consumption. (author)

    1987-01-01

    This paper discusses an evaluation methodology which is used for inventory differences at the Los Alamos National Laboratory. It is recognized that there are various methods which can be, and are being, used to evaluate process inventory differences at DOE facilities. The purpose of this paper is to share our thoughts on the subject and our techniques with those who are responsible for the evaluation of inventory differences at their facility. One of the most dangerous aspects of any evaluation technique, especially one as complex as most inventory difference evaluations tend to be, is to fail to look at the tools being used as indicators. There is a tendency to look at the results of an evaluation by one technique as an absolute. At the Los Alamos National Laboratory, several tools are used and the final evaluation is based on a combination of the observed results of a many-faceted evaluation. The tools used and some examples are presented

    The Evaluation Toolkit and Community project is a new Digital Library for Earth System Education (DLESE) collection designed to raise awareness of project evaluation within the geoscience education community, and to enable principal investigators, teachers, and evaluators to implement project evaluation more readily. This new resource is grounded in the needs of geoscience educators, and will provide a virtual home for a geoscience education evaluation community. The goals of the project are to 1) provide a robust collection of evaluation resources useful for Earth systems educators, 2) establish a forum and community for evaluation dialogue within DLESE, and 3) disseminate the resources through the DLESE infrastructure and through professional society workshops and proceedings. Collaboration and expertise in education, geoscience and evaluation are necessary if we are to conduct the best possible geoscience education. The Toolkit allows users to engage in evaluation at whichever level best suits their needs, get more evaluation professional development if desired, and access the expertise of other segments of the community. To date, a test web site has been built and populated, initial community feedback from the DLESE and broader community is being garnered, and we have begun to heighten awareness of geoscience education evaluation within our community. The web site contains features that allow users to access professional development about evaluation, search and find evaluation resources, submit resources, find or offer evaluation services, sign up for upcoming workshops, take the user survey, and submit calendar items. The evaluation resource matrix currently contains resources that have met our initial review. The resources are currently organized by type; they will become searchable on multiple dimensions of project type, audience, objectives and evaluation resource type as efforts to develop a collection-specific search engine mature.

    Full Text Available This paper is a short tutorial introduction to online partial evaluation. We show how to write a simple online partial evaluator for a simple, pure, first-order, functional programming language. In particular, we show that the partial evaluator can be derived as a variation on a compositionally defined interpreter. We demonstrate the use of the resulting partial evaluator for program optimization in the context of model-driven development.

    1989-01-01

    The SAIC has the responsibility for independent test and validation of the SSE. They have been using a mathematical functions library package implemented in Ada to test the SSE IV and V process. The library package consists of elementary mathematical functions and is both machine and accuracy independent. The SSE Ada components evaluation includes code complexity metrics based on Halstead's software science metrics and McCabe's measure of cyclomatic complexity. Halstead's metrics are based on the number of operators and operands on a logical unit of code and are compiled from the number of distinct operators, distinct operands, and total number of occurrences of operators and operands. These metrics give an indication of the physical size of a program in terms of operators and operands and are used diagnostically to point to potential problems. McCabe's Cyclomatic Complexity Metrics (CCM) are compiled from flow charts transformed to equivalent directed graphs. The CCM is a measure of the total number of linearly independent paths through the code's control structure. These metrics were computed for the Ada mathematical functions library using Software Automated Verification and Validation (SAVVAS), the SSE IV and V tool. A table with selected results was shown, indicating that most of these routines are of good quality. Thresholds for the Halstead measures indicate poor quality if the length metric exceeds 260 or difficulty is greater than 190. The McCabe CCM indicated a high quality of software products.

    A multifrequency ACPD system was assembled which can measure very small crack. Stress corrosion cracking test system with SSRT operating high temperature was installed. Stress corrosion cracking test of newly developed alloy 600 and existing alloy 600 was carried out in steam atmosphere of 400 deg C. No crack was observed in both materials within a test period of 2,000 hrs. Corrosion fatigue test system operating at high temperature was installed in which fatigue crack was measured by CDPD. Lead enhanced the SCC of the Alloy 600 in high temperature water, had a tendency to modify a cracking morphology from intergranular to transgranular. Pit initiation preferentially occurred at Ti-rich carbide. Resistance to pit initiation decreased with increasing temperature up to 300 deg C. Test loop for erosion corrosion was designed and fabricated. Thin layer activation technique was very effective in measuring erosion corrosion. Erosion corrosion of a part of secondary side pipe was evaluated by the Check Family Codes of EPRI. Calculated values of pipe thickness by Check Family Codes coincided with the pipe thickness measured by UT with an error of ± 20%. Literature review on turbine failure showed that failure usually occurred in low pressure turbine rotor disc and causes of failure are stress corrosion cracking and corrosion fatigue.

    Full Text Available In present, innovations are spoken as an engine of the world economy because the innovations are transforming not only business entities but the whole industries. The innovations have become a necessity for business entities in order to survive on floating challenging markets. This way, innovations are driving force of companies’ performance. The problem which arises here is a question of measurement innovation’s effect on the financial performance of company or selection between two or more possible variants of innovation’s realization. Various authors which are focused on innovations processes are divided into two groups in their attitudes towards the question of influence of innovations on financial performance of companies. One group of the authors present the idea that any reliable measurement is not possible or efficient. The second group of authors present some methods theoretically applicable on this measurement but they base their approaches mostly on the methods of measurement of investments effectiveness or they suggest employment of indicators or ratios which wouldn’t be clearly connected with the outcome of innovation process. The aim of submitted article is to compare different approaches to evaluation of the innovation processes. The authors compare various approaches here and by use of analysis and synthesis, they determine their own method how to measure outcome of innovation process.

    Full Text Available Using a cognitive task (mental calculation and a perceptual-motor task (stylized golf putting, we examined differential proficiency using the CWS index and several other quantitative measures of performance. The CWS index (Weiss and Shanteau, 2003 is a coherence criterion that looks only at internal properties of the data without incorporating an external standard. In Experiment 1, college students (n = 20 carried out 2- and 3-digit addition and multiplication problems under time pressure. In Experiment 2, experienced golfers (n = 12, also college students, putted toward a target from nine different locations. Within each experiment, we analyzed the same responses using different methods. For the arithmetic tasks, accuracy information (mean absolute deviation from the correct answer, MAD using a coherence criterion was available; for golf, accuracy information using a correspondence criterion (mean deviation from the target, also MAD was available. We ranked the performances of the participants according to each measure, then compared the orders using Spearman's rextsubscript{s}. For mental calculation, the CWS order correlated moderately (rextsubscript{s} =.46 with that of MAD. However, a different coherence criterion, degree of model fit, did not correlate with either CWS or accuracy. For putting, the ranking generated by CWS correlated .68 with that generated by MAD. Consensual answers were also available for both experiments, and the rankings they generated correlated highly with those of MAD. The coherence vs. correspondence distinction did not map well onto criteria for performance evaluation.

  2. Evaluating gambles using dynamics

    Science.gov (United States)

    Peters, O.; Gell-Mann, M.

    2016-02-01

    Gambles are random variables that model possible changes in wealth. Classic decision theory transforms money into utility through a utility function and defines the value of a gamble as the expectation value of utility changes. Utility functions aim to capture individual psychological characteristics, but their generality limits predictive power. Expectation value maximizers are defined as rational in economics, but expectation values are only meaningful in the presence of ensembles or in systems with ergodic properties, whereas decision-makers have no access to ensembles, and the variables representing wealth in the usual growth models do not have the relevant ergodic properties. Simultaneously addressing the shortcomings of utility and those of expectations, we propose to evaluate gambles by averaging wealth growth over time. No utility function is needed, but a dynamic must be specified to compute time averages. Linear and logarithmic "utility functions" appear as transformations that generate ergodic observables for purely additive and purely multiplicative dynamics, respectively. We highlight inconsistencies throughout the development of decision theory, whose correction clarifies that our perspective is legitimate. These invalidate a commonly cited argument for bounded utility functions.

    The U.S. Department of Energy-Headquarters (DOE-HQ), Transportation Management Program (TMP) has the overall responsibility to provide a well-managed transportation program for the safe, efficient, and economical transportation of DOE-owned materials. The DOE-TMP has established an excellent safety record in the transportation of hazardous materials including radioactive materials and radioactive wastes. This safety record can be maintained only through continued diligence and sustained effort on the part of the DOE-TMP, its field offices, and the contractors' organizations. Key elements in the DOE'S effective hazardous and radioactive materials shipping program are (1) integrity of packages, (2) strict adherence to regulations and procedures, (3) trained personnel, (4) complete management support, and (5) use of the best commercial carriers. The DOE Motor Carrier Evaluation Program was developed to better define the criteria and methodology needed to identify motor carriers for use in the transportation of Highway Route Controlled Quantities (HRCQ), Truck Load (TL) quantities of radioactive materials, hazardous materials and waste.

    2011-01-01

    Full Text Available Background: Glass ionomer cements are widely used in pediatric practice due to their advantage of fluoride release and chemical bond to tooth structure. Adherence of the restorative material to the cavity walls is one of the most important characteristic for it to be proven as an ideal material as it prevents microleakage. Aims and Objectives: This study was aimed at evaluating the microleakage of nanofilled resin-modified glass ionomer cement compared with the conventional and resin-modified glass ionomer cements. Materials and Methods: Standard class V cavities of size 3 mm x 2 mm x 2 mm were made on a total of 30 extracted teeth and restored with the conventional glass ionomer, resin-modified glass ionomer or nanoionomer. After thermocycling, teeth were immersed in 0.5% methylene blue dye for 24 h. They were then sectioned buccolingually. Microleakage was assessed for the occlusal and gingival walls using a compound microscope by two examiners independently. Results: Nanoionomer demonstrated the least microleakage, with a mean score of 1.3, compared with the resin-modified glass ionomer (score of 3.2 and conventional glass ionomer cement (score 2.6. Conclusion: Nanoionomer exhibited adequate resistance to microleakage and thus may prove better than conventional or resin-modified glass ionomers.

    Commercial electric power generation, nuclear weapons production, the operation of naval reactors, and research and development activities produce spent nuclear fuel and high-level radioactive waste. Spent nuclear fuel and high-level radioactive waste have been accumulating at commercial reactor sites and storage facilities across the country since 1957. Spent nuclear fuel and high-level radioactive waste have been accumulating at sites now managed by U.S. Department of Energy (DOE) since the mid-1940s. The DOE has the statutory obligation to dispose of these wastes. The U.S. has studied methods for the safe storage and disposal of radioactive waste for more than 40 years. Many organizations and government agencies have participated in these studies. In the 1950s, the U.S. Atomic Energy Commission requested the National Academy of Sciences to evaluate options for land disposal of radioactive waste. The U.S. Atomic Energy Commission and its successor agencies, the Energy Research and Development Administration and the DOE, continued to analyze radioactive waste management options throughout the 1960s and 1970s. In 1979, an Interagency Review Group that included representatives of 14 federal government entities provided findings and recommendations to the President. After analyzing a range of options, disposal in a geologic repository emerged as the preferred long-term environmental solution. This consensus is reflected in the Nuclear Waste Policy Act of 1982 (NWPA). The NWPA and related statutes established the framework for addressing the issues of radioactive waste disposal and designated the roles and responsibilities of the federal government and the owners and generators of the waste

  10. Screening Risk Evaluation methodology

    International Nuclear Information System (INIS)

    Hopper, K.M.

    1994-01-01

    The Screening Risk Evaluation (SRE) Guidance document is a set of guidelines provided for the uniform implementation of SREs performed on D ampersand D facilities. These guidelines are designed specifically for the completion of the second (semi-quantitative screening) phase of the D ampersand D Risk-Based Process. The SRE Guidance produces screening risk scores reflecting levels of risk through the use of risk ranking indices. Five types of possible risk are calculated from the SRE: current releases, worker exposures, future releases, physical hazards, and criticality. The Current Release Index (CRI) calculates the risk to human health and the environment from ongoing or probable releases within a one year time period. The Worker Exposure Index (WEI) calculates the risk to workers, occupants, and visitors in D ampersand D facilities of contaminant exposure. The Future Release Index (FRI) calculates the risk of future releases of contaminants, after one year, to human health and the environment. The Physical Hazards Index (PHI) calculates the risk-to human health due to factors other than that of contaminants. The index of Criticality is approached as a modifying factor to the entire SRE, due to the fact that criticality issues are strictly regulated under DOE. Screening risk results will be tabulated in matrix form and Total Risk will be calculated (weighted equation) to produce a score on which to base early action recommendations. Other recommendations from the screening risk scores will be made based either on individual index scores or from reweighted Total Risk calculations. All recommendations based on the SRE will be made based on a combination of screening risk scores, decision drivers, and other considerations, determined on a project by project basis. The SRE is the first and most important step in the overall D ampersand D project level decision making process

    2009-12-01

    Full Text Available Background: Coronary heart disease (CHD is a common and potentially fatal malady with a life time prevalence of over 20%. For Germany, the mortality attributable to chronic ischemic heart disease or acute myocardial infarction is estimated at 140,000 deaths per year. An association between prognosis of CHD and lifestyle risk factors has been consistently shown. To positively influence lifestyle risk factors in patients with CHD, non-pharmaceutical secondary prevention strategies are frequently recommended and implemented. Objectives: The aim of this HTA (HTA = Health Technology Assessment is to summarise the current literature on strategies for non-pharmaceutical secondary prevention in patients with CHD and to evaluate their medical effectiveness/efficacy and cost-effectiveness as well as the ethical, social and legal implications. In addition, this report aims to compare the effectiveness and efficacy of different intervention components and to evaluate the generalisability with regard to the German context. Methods: Relevant publications were identified by means of a structured search of databases accessed through the German Institute of Medical Documentation and Information (DIMDI. In addition, a manual search of identified reference lists was conducted. The present report includes German and English literature published between January 2003 and September 2008 targeting adults with CHD. The methodological quality of included studies was assessed according to pre-defined quality criteria, based on the criteria of evidence based medicine. Results: Among 9,074 publications 43 medical publications met the inclusion criteria. Overall study quality is satisfactory, but only half the studies report overall mortality or cardiac mortality as an outcome, while the remaining studies report less reliable outcome parameters. The follow-up duration varies between twelve and 120 months. Although overall effectiveness of non-pharmaceutical secondary

    Full Text Available Cerebral aging is a major public health issue in our societies as the aged population increases dramatically. It leads in many cases to neurodegenerative diseases such as Alzheimer disease (AD. Rodents and particularly transgenic mice are widely used as models for research on physiopathology of cerebral aging, neurodegenerative diseases and for the evaluation of therapies. However these models do not mimic all the pathophysiological aspects of human diseases. Complementary models such as non-human primates are phylogenetically close to humans and thus more predictive of drug efficiency in humans. Mouse lemur (Microcebus murinus is a small primate (about 12cm, 100g described as a useful model of cerebral aging and as a potential model of AD. Indeed several animals develop age-associated cerebral alterations like amyloidosis and other cerebral changes. Non invasive medical imaging methods such as magnetic resonance imaging (MRI can be used to follow-up brain changes in these animals. In this review, we present how mouse lemurs can be followed-up by MRI and how MRI can be used during therapeutic evaluations and other applications in this model. MR images can be used to follow-up cerebral anatomy in mouse lemurs. It allows for the description of age-associated atrophic processes, age-associated iron accumulation, and vascular anatomy (thanks to MR angiography. Cerebral glucose uptake can be studied in mouse lemurs with other in vivo imaging modalities such as positron emission tomography (PET. In this case, MRI can be used as a support for quantification of radioligand uptake in specific structures. Ex vivo MR imaging is another MR protocol that can be used to describe cerebral aging in lemurs. It provides high resolution 3D histological brain images and allows for studying exquisite anatomical details or microhemorrhages. Finally, MRI can be used to practice cerebral surgery in lemurs and determine coordinates for stereotactic injections. It can

  13. Neoliberalization by Evaluation: Explaining the Making of Neoliberal Evaluative State

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Starting from the late seventies neoliberalism has emerged as the new global hegemonic par-adigm. Several studies demonstrated that different factors facilitated the global spread of neoliberalism, but little attention has been paid to the role played by evaluation both in legitimizing the neoliberalization of the state and in explaining the resilience of neoliberalism. The article argues that evaluation is a strategy of action which is able to emphasize the adaptive capacity of neoliberalism to different socio-political con-texts and the neoliberal purpose to depoliticize public action. The contribution aims to illustrate how eval-uation works on a twofold level. On the one hand, evaluation is a tool of global governance that acts nor-matively to homogenize states’ action consistently with some neoliberal values, such as competitiveness and economic efficiency. On the other hand, to conform to such values, variegated forms of evaluation are implemented by each state in order to introduce market rationality in non-economic domains, such as ed-ucation and health system. Referring to some empirical cases, these two overlapping processes are termed as the "evaluated state" and "evaluative state". As a result, neoliberalization by evaluation is a process in-volving the elevation of market-based principles and techniques of evaluation to the level of state-endorsed norms

I then produce an impartial division rule that never underpays or overpays any agent by more than one-third of a dollar, and for most consistent evaluation profiles does much better.

  3. Safeguards Evaluation Method for evaluating vulnerability to insider threats

    International Nuclear Information System (INIS)

    Al-Ayat, R.A.; Judd, B.R.; Renis, T.A.

    1986-01-01

    As protection of DOE facilities against outsiders increases to acceptable levels, attention is shifting toward achieving comparable protection against insiders. Since threats and protection measures for insiders are substantially different from those for outsiders, new perspectives and approaches are needed. One such approach is the Safeguards Evaluation Method. This method helps in assessing safeguards vulnerabilities to theft or diversion of special nuclear meterial (SNM) by insiders. The Safeguards Evaluation Method-Insider Threat is a simple model that can be used by safeguards and security planners to evaluate safeguards and proposed upgrades at their own facilities. The method is used to evaluate the effectiveness of safeguards in both timely detection (in time to prevent theft) and late detection (after-the-fact). The method considers the various types of potential insider adversaries working alone or in collusion with other insiders. The approach can be used for a wide variety of facilities with various quantities and forms of SNM. An Evaluation Workbook provides documentation of the baseline assessment; this simplifies subsequent on-site appraisals. Quantitative evaluation is facilitated by an accompanying computer program. The method significantly increases an evaluation team's on-site analytical capabilities, thereby producing a more thorough and accurate safeguards evaluation

    Both the initial evaluation and follow-up of patients with osteoarthritis require systematic evaluation of the indicators that provide information on the degree of involvement of the disease and allow its quantification. Reliable measures of disease progression help decision-making by clinicians and provide valid information on treatment response and the effectiveness of the distinct therapeutic interventions. The instruments recommended in research, as outcome measures in osteoarthritis, are pain evaluation, assessment of physical function, and self-reported global evaluation. In studies lasting more than 1 year, structural changes are evaluated through simple X-ray. Self-reported quality of life assessment and physician global assessment are also recommended as options. These indicators should be incorporated into routine clinical practice for adequate evaluation and correct follow-up of patients with osteoarthritis. The recommended pain evaluation method for use in clinical practice is the visual analog scale (VAS). The best instrument to evaluate physical function in patients with hip or knee osteoarthritis is the WOMAC scale (Western Ontario and McMaster Universities Osteoarthritis Index). For patient-reported global assessment in routine practice, the recommended scales are VAS or the SF-12 (12-item short-form health survey). Copyright © 2014 Elsevier España, S.L.

    The Remote Primary Health Care Manuals (RPHCM) project team manages the development and publication of clinical protocols and procedures for primary care clinicians practicing in remote Australia. The Central Australian Rural Practitioners Association Standard Treatment Manual, the flagship manual of the RPHCM suite, has been evaluated for accessibility and acceptability in remote clinics three times in its 20-year history. These evaluations did not consider a theory-based framework or a programme theory, resulting in some limitations with the evaluation findings. With the RPHCM having an aim of enabling evidence-based practice in remote clinics and anecdotally reported to do so, testing this empirically for the full suite is vital for both stakeholders and future editions of the RPHCM. The project team utilized a realist evaluation framework to assess how, why and for what the RPHCM were being used by remote practitioners. A theory regarding the circumstances in which the manuals have and have not enabled evidence-based practice in the remote clinical context was tested. The project assessed this theory for all the manuals in the RPHCM suite, across government and aboriginal community-controlled clinics, in three regions of Australia. Implementing a realist evaluation framework to generate robust findings in this context has required innovation in the evaluation design and adaptation by researchers. This article captures the RPHCM team's experience in designing this evaluation. © 2015 John Wiley & Sons, Ltd.

  1. Evaluation of Probabilistic Disease Forecasts.

    Science.gov (United States)

    Hughes, Gareth; Burnett, Fiona J

    2017-10-01

    The statistical evaluation of probabilistic disease forecasts often involves calculation of metrics defined conditionally on disease status, such as sensitivity and specificity. However, for the purpose of disease management decision making, metrics defined conditionally on the result of the forecast-predictive values-are also important, although less frequently reported. In this context, the application of scoring rules in the evaluation of probabilistic disease forecasts is discussed. An index of separation with application in the evaluation of probabilistic disease forecasts, described in the clinical literature, is also considered and its relation to scoring rules illustrated. Scoring rules provide a principled basis for the evaluation of probabilistic forecasts used in plant disease management. In particular, the decomposition of scoring rules into interpretable components is an advantageous feature of their application in the evaluation of disease forecasts.

    Sandia National Laboratories has tested and evaluated an updated SMAD digitizer, developed by the French Alternative Energies and Atomic Energy Commission (CEA). The SMAD digitizers are intended to record sensor output for seismic and infrasound monitoring applications. The purpose of this digitizer evaluation is to measure the performance characteristics in such areas as power consumption, input impedance, sensitivity, full scale, self-noise, dynamic range, system noise, response, passband, and timing. The SMAD digitizers have been updated since their last evaluation by Sandia to improve their performance when recording at a sample rate of 20 Hz for infrasound applications and 100 Hz for hydro-acoustic seismic stations. This evaluation focuses primarily on the 20 Hz and 100 Hz sample rates. The SMAD digitizers are being evaluated for potential use in the International Monitoring System (IMS) of the Comprehensive Nuclear Test- Ban-Treaty Organization (CTBTO).

    Arthur, E.D.; Chadwick, M.B.; Hale, G.M.; Young, P.G.

    1991-01-01

    The widespread use of nuclear models continues in the creation of data evaluations. The reasons include extension of data evaluations to higher energies, creation of data libraries for isotopic components of natural materials, and production of evaluations for radiative target species. In these cases, experimental data are often sparse or nonexistent. As this trend continues, the nuclear models employed in evaluation work move towards more microscopically-based theoretical methods, prompted in part by the availability of increasingly powerful computational resources. Advances in nuclear models applicable to evaluation will be reviewed. These include advances in optical model theory, microscopic and phenomenological state and level density theory, unified models that consistently describe both equilibrium and nonequilibrium reaction mechanism, and improved methodologies for calculation of prompt radiation from fission. 84 refs., 8 figs

    2015-12-01

    The role of politics has often been discussed in evaluation theory and practice. The political influence of the situation can have major effects on the evaluation design, approach and methods. Politics also has the potential to influence the decisions made from the evaluation findings. The current study focuses on the influence of the political context on stakeholder decision making. Utilizing a simulation scenario, this study compares stakeholder decision making in high and low stakes evaluation contexts. Findings suggest that high stakes political environments are more likely than low stakes environments to lead to reduced reliance on technically appropriate measures and increased dependence on measures better reflect the broader political environment.

    2011-01-01

    The traditional system of academic promotion and tenure can make it difficult to reward those who excel at surgical teaching. A successful faculty evaluation process can provide the objective measures of teaching performance needed for performance appraisals and promotion decisions. Over the course of two decades, an extensive faculty evaluation process has been developed in the Department of Surgery at the University of Toronto. This paper presents some of the non-psychometric characteristics of that system. Faculty awareness of the evaluation process, the consistency of its application, trainee anonymity and the materiality of the results are described key factors of a faculty evaluation system that meets the assessment needs of individual teachers and raises the profile of teaching in surgical departments.

    2015-06-01

    Full Text Available Property evaluation for tax purposes has traditionally relied on urban and building criteria, mostly resulting from concepts driven by the commercial attractiveness of the property under evaluation, its building and the site itself. Due to the world climate and ecological crisis, awareness has risen about the need for other indicators, which can evaluate the quality of a property, even referring to its potential environmental impact. Technical standards for the evaluation of buildings’ environmental sustainability, which have been developed since the first years of this century, both nationally and internationally, take into account the impact of the building and its relevance for the life-cycle of materials and elements, with reference to the three sectors of sustainability: environmental, economic and social. The social sector includes indicators referring to the user’s health and comfort, which also interact with the morphological and spatial characteristics of the building. However, there is a lack of methodological tools for the evaluation of said indicators and existing ones are mainly of a qualitative type. This paper suggests a methodological approach for the quantitative evaluation of sustainability indicators, relying on the accessibility of a site’s climate resources by the property, as a criterion to evaluate the potential for the reduction of negative environmental impact, as well as a criterion to improve users’ life quality.

  14. Evaluating Methods for Evaluating Instruction: The Case of Higher Education

    OpenAIRE

    Bruce A. Weinberg; Belton M. Fleisher; Masanori Hashimoto

    2007-01-01

    This paper develops an original measure of learning in higher education, based on grades in subsequent courses. Using this measure of learning, this paper shows that student evaluations are positively related to current grades but unrelated to learning once current grades are controlled. It offers evidence that the weak relationship between learning and student evaluations arises, in part, because students are unaware of how much they have learned in a course. The paper concludes with a discu...

  15. Constructionism, postmodernism and evaluation theory. The strategic function of evaluation

    Directory of Open Access Journals (Sweden)

    Baltasar Fernández-Ramírez

    2009-05-01

    Full Text Available "Testing"  and "evaluating" are money-making activities that offer a rewarding professional career; perhaps it is no surprise that the field includes numbers of self-styled "evaluators" who provide services without the required training. Evaluation means the systematic application of given criteria for judging the merit or value of a variety of 'assessables' - capacities, powers and services, including social policy interventions. The conventional perspective is rationalist (in diagnosis, planning, intervention and impact analysis, even though rationalism have lost their pre-eminence in the social sciences, in favour of political, symbolic or chaotic alternatives, as the history of organizational thought reveals. Alternatively, from a constructionist perspective, we see the power of evaluation criteria to reify what they ostensibly assess. Evaluations suggest or impose what is right; criteria of value define, give meaning and prioritize just one way of understanding social relations, program goals or individual and organizational behaviour. The suggestion in this article is to make a positive virtue of this inevitable pragmatic consequence of evaluation: to openly embrace it as an agent of change, emphasizing a strategical function beyond the traditional purposes of enhancement and accountability.

    Pearlstein, S.

    1985-01-01

    This paper summarizes the principal national and international evaluation activities that contributed to the widespread use of evaluated data files. Emphasis is placed on those efforts that have become best known through the availability of data, documentation, and computer codes. Early attempts at nuclear data evaluation consisted of improving communication among measurers of similar information. As reactor methodology proceeded from a four factor formula to multi-group theory the demand for detailed representation of nuclear data increased. The systematic access to large volumes of data required placing the information in computer readable formats

    2017-01-01

    Abstract Background: Information and communication sources in the healthcare sector are replaced with new eHealth technologies. This has led to problems arising from the lack of awareness of the importance of end-user involvement in eHealth development and of the difficulties caused by using...... traditional summative evaluation methods. The Constructive eHealth evaluation method (CeHEM) provides a solution to these problems by offering an evaluation framework for supporting and facilitating end-user involvement during all phases of eHealth development. The aim of this paper is to support this process...... by sharing experiences of the eHealth evaluation method used in the introduction of electronic health records (EHR) in the North Denmark Region of Denmark. It is the first time the fully developed method and the experiences on using the CeHEM in all five phases of a full lifecycle framework is presented...

    1989-01-01

    A simple method of sonographic (US) evaluation of penile and bulbous urethra is reported. Twenty-three dysuric patients were examined. They were divided into 2 groups according to their pathology. The US patterns of normal urethra were evaluated in 10 patients (first group) with no obstructive lesions. Urethral and periurethral structure were examined in 13 patients (second group) with urethral obstructive pathology. All patients underwent conventional cystourethrography. The diagnostic parameters considered were urethral gauge and thickness, echogenicity of the urethral wall, and Cowper's glands. US evaluation of obstructive lesions provided the same findings as conventional radiological techniques. Moreover, US allowed the evaluation of both thickness and echogenicity of the urethral wall and of normal/injured Cowper's glands

    The first HTA guidelines for Thailand included a chapter outlining a set of guidelines on how best to report the findings of health economic evaluations, based on a review of best practice and existing guidelines on the presentation of economic evaluation results from around the world. In this second edition of HTA guidelines for Thailand, the recommendations build on the first edition by using a case study to illustrate how the guidelines can be applied in a real research context. The guidelines propose that all reporting include ten key elements: defining the scope of the study, selection of comparator(s), defining the type of economic evaluation, measurement of costs, measurement of clinical effects, handling time in economic evaluation studies, handling uncertainty and sensitivity analysis, presentation of the results, discussion of the results, and disclosure of funding and authors conflict of interest.

    Melina Gabriela Furman

    2012-06-01

    Full Text Available This research analyzes the final evaluations of the major in Biology Teaching in an institution in northeastern Argentina. The evaluation circumstances were observed, and the professors were subsequently interviewed. The questions formulated by the professors in the test were analyzed according to the objective of their speech and the dimension of the evaluated sciences, by using the categories of science as a product (set of knowledge and as a process (ways to know. 78% of the questions correspond to the category of science as a product compared to 22% as a process. Most of the formulated questions aimed to lowcomplex cognitive processes such as the enunciation of definitions or descriptions, and simple scientific skills as classifying. These results contradict professors’ concern about their students’ low level of reading comprehension and their stated objective of ‘teaching them to think’. This paper brings evidences as for the imperative need of strengthening the work with teacher trainers in learning evaluation aspects.
