    Le nombre et la durée de survie des patients transplantés cardiaque sont en augmentation. Une partie de ces patients se présentent régulièrement pour une chirurgie générale en dehors de la transplantation cardiaque. L’anesthésie chez ces patients peut être difficile en raison des particularités physiologiques du cœur dénervé et de la gestion du traitement immunosuppresseur avec le risque de rejet et d’infection. Nous discutons la prise en charge anesthésique à travers un cas d’un patient âgé de 60 ans transplanté cardiaque devant subir une chirurgie de cure d’éventration abdominale et une revue de la littérature.

    Introduction L'incidence des complications respiratoires postopératoires (CRPO) reste très diversement appréciées selon les critères diagnostiques retenues dans les différentes études, ce qui la fait varier de 5 à plus de 50%. Les CRPO majeurs après chirurgie de l'aorte abdominale sont responsables d'une grande morbi-mortalité pouvant aller jusqu’à 36%, d'une durée d'hospitalisation et d'un coût plus importants. Ainsi dans l'optique d'améliorer notre prise en charge périopératoire de la chirurgie de l'aorte, nous avons décidé de mener une étude pour dresser le profil épidémiologique et déterminer les facteurs de risque des complications respiratoires dans notre contexte Méthodes Il s'agit d'une étude de cohorte rétrospective du mois de Janvier 2007 au mois de décembre 2011 portant sur l'ensemble des patients opérés pour pathologie aortique au bloc opératoire central de l'hôpital Ibn Sina de Rabat, Maroc. Résultats Cent vingt cinq patients ont été inclus dans notre étude, 24 patients ont été opérés pour anévrysme de l'aorte abdominale et 101 patients pour lésion occlusive aortoiliaque. Dans notre série 22 malades soit 17,6% ont présenté une complication respiratoire majeure avec, une reventilation dans 4,8% des cas, une difficulté de sevrage de la ventilation artificielle dans 3,2% des cas, une pneumopathie dans 4% des cas, un syndrome de détresse respiratoire aigue (SDRA) dans 4% des cas et une nécessité de fibroaspiration bronchique dans 1,6% des cas. En analyse univariée: l’âge, la présence d'une BPCO avec dyspnée stade 3 ou 4, la présence d'une anomalie à l'EFR préopératoire, la présence d'un stade avancé (III ou IV) de LOAI et la reprise chirurgicale étaient statistiquement associés à la survenue d'une complication respiratoire postopératoire. En analyse multivariée, seule une anomalie à l'EFR en préopératoire constituait un facteur de risque indépendant de survenue d'une complication

    La cataracte congénitale constitue la cause la plus fréquente de cécité évitable chez les enfants. Le but de cette étude est d’évaluer le pronostic réfractif et fonctionnel, des enfants opérés de cataracte congénitale avec implantation. Il s'agit d'une étude rétrospective de 108 enfants, dont 85 cataractes bilatérales, 23 unilatérales opérés entre 2007 et 2011. La réfraction a été mesurée à 1 mois, 3 mois, 6 mois, 1 an, 2 ans, 3 ans et/ou 4 ans en post-opératoire. La meilleure acuité visuelle corrigée, ainsi que l'incidence des complications post-opératoires ont été analysé. L’âge moyen de la chirurgie était de 25 mois avec une durée moyenne de suivi de 3,17 ans. Les complications retrouvées étaient l'inflammation, la prolifération secondaire, et le glaucome. L'acuité visuelle (AV) moyenne corrigée finale était de 5,75/10e pour les formes bilatérales, et de 4,16/10e pour les unilatérales (p = 0,001). Les facteurs de mauvais pronostic retrouvés étaient l’âge tardif de la chirurgie, la densité de la cataracte et la survenue de complications (p = 0,001). L'incidence des complications post-opératoires était significativement plus élevé chez les enfants opérés à un jeune âge (p = 0,001). Les facteurs de mauvais pronostic visuel chez les enfants opérés pour cataracte congénitale avec implantation, sont représentés par le caractère unilatéral de la cataracte, l’âge tardif de la chirurgie, la densité de la cataracte et la survenue de complications post opératoires.

    Full Text Available INTRODUCTION: Concernant l’hydatidose, la localisation splénique vient en 3ème position après le foie et les poumons. En l’absence de traitement médical réellement efficace, l’hydatidose splénique amène souvent à la chirurgie. L’apparition du traitement percutané et la tendance actuellement conservatrice de la chirurgie surtout pour une pathologie bénigne, remettent en cause la splénectomie radicale. METHODES: Notre travail rétrospectif, a porté sur 23 cas d’hydatidose splénique isolés ou multi-viscérale. Le diagnostic reposait principalement sur le couple échographie abdominale et sérologie hydatique. Ces patients ont bénéficié dans leur majorité d’une splénectomie ou d’une résection du dôme saillant du kyste. RESULTATS: La morbidité postopératoire a été plus importante en cas de résection du dôme saillant (une hémorragie d’origine splénique, 3 abcès sur cavité résiduelle et 2 récidives. La mortalité a été nulle. Nous proposons une classification qui permet de stratifier les indications opératoires en fonction du type de kyste hydatique de la rate. CONCLUSION: Le choix entre chirurgie radicale ou conservatrice reste difficile vu les contraintes de chacune, les complications postopératoires respectives et la diversité des situations cliniques. Notre classification facilite ce choix.

  6. Chirurgie in die Grieks-Romeinse era

    Full Text Available In die Grieks-Romeinse era het mediese behandeling kenmerkend uit drie elemente bestaan, naamlik regimen (dieet en gesonde leefwyse, geneesmiddels en chirurgie – laasgenoemde alleen toegepas indien regimen en geneesmiddels onsuksesvol was. Bewyse van primitiewe chirurgie dateer terug na die Bronstydperk, en in Homerus se eposse is heelwat vermelding van die chirurgiese hantering van oorlogswonde, met tussenkoms van die gode. Met die koms van empiriese geneeskunde in die 5de eeu v.C. het chirurgie in die Hippokratiese Corpus prominent gefigureer met beduidende bydraes in veral die ortopediese veld en hoofbeserings. Uitbouing van anatomiese en fisiologiese kennis, gebaseer op disseksie van menslike kadawers in Alexandrië vanaf die laat 4de eeu v.C., het chirurgie ’n hupstoot gegee. Teen die Romeinse era vanaf die 2de eeu v.C. het snykundetegnieke (en -instrumente beduidend verbeter, maar is steeds oorwegend deur Griekse geneeshere beoefen. Van geneeshere is steeds verwag om al drie bovermelde terapeutiese modaliteite te bemeester, maar chirurgie het meer aansien verwerf en daar is al meer in onderafdelings van chirurgie soos oogheelkunde, vrouesiektes en verloskunde, blaaskwale en mond- en keelsnykunde gespesialiseer. Militêre geneeskunde was in die Romeinse Ryk ’n belangrike aktiwiteit, en het veral traumachirurgie uitgebou. Betreding van die buik- en toraksholtes was nie meer noodwendig fataal nie, en veeartsenykunde het tot stand gekom. Die eerste beduidende chirurgiehandboek ná die Hippokratiese Corpus is in die 1ste eeu n.C. deur Celsus opgestel. Vanaf die 3de eeu het die chirurgieberoep min vordering gemaak, die beroepstaal het mettertyd van Grieks na Latyn verander en kundigheid is later veral deur Islam-geneeshere na die Middeleeue en later oorgedra.

    La thrombose intracardiaque est une complication rare de la maladie de Behçet (MB), qui peut se présenter comme une tumeur intracardiaque. Sa découverte précède, dans la moitié des cas, le diagnostic de MB. La mortalité élevée peut être en rapport avec des complications post-chirurgicales et/ou une atteinte associée des artères pulmonaires. Nous rapportons l’observation d’un jeune patient de 29 ans, aux antécédents d’aphtose bipolaire, qui a bénéficie d’une intervention chirurgicale après la découverte d’une tumeur de l’atrium et du ventricule droits. Il s’agissait d’un thrombus à l’examen anatomopathologique et dans les suites opératoires nous avons diagnostiqué une MB. L’évolution a été favorable sous traitement médical associant une corticothérapie, de la colchicine et des antivitamines K (AVK). La découverte d’une masse intracardiaque chez un sujet jeune doit faire évoquer le diagnostic de thrombus cardiaque et de maladie de Behçet, même en l’absence de facteur ethnique ou géographique prédisposant.

    2007-08-01

    The history of modern plastic surgery starts when a young, restless ENT man, Dr M. Coelst, started a training in Plastic Surgery with Sebileau in Paris and Joseph in Berlin. This man of vision and far-sighted imagination realized that the separated efforts and publications of so many pioneers, scaterred all over the world, would be lost if not gathered in a scientific journal only devoted to plastic surgery for the benefit of all. This brought him to the idea of establishing, in 1931, at his own initiative, the first international Journal of Plastic Surgery ever published, the Revue de Chirurgie Plastique, fifteen years before the USA Journal Plastic and Reconstructive Surgery and sixteen years before the British Journal of Plastic Surgery. The name of the journal was changed in 1935 to the Revue de Chirurgie Structive. Coelst' Revue was promptly accepted as the leading Journal of Plastic Surgery and all the internationally known plastic Surgeons contributed to it by scientific papers of great value, even today.

    The Revue de Chirurgie Plastique and the Revue de Chirurgie Structive, Brussels (1931-1938), edited by Maurice Coelst, M.D. from Brussels, were the first, full-fledged medical publications specifically devoted to plastic, reconstructive, and aesthetic surgery. Publishing original articles by J.W. Maliniac, J. Eastman Sheehan, and brief summaries of papers read at plastic surgery societies by C.R. Straatsma, L.A. Peer, G. Aufricht, and other well-known American plastic surgeons, these Revues drew attention to surgeons, most of whom were responsible for organizing the American Society of Plastic and Reconstructive Surgeons in 1931, the same year in which the Revue de Chirurgie Plastique first appeared.

    The Second Generation Airborne Precipitation Radar (APR-2) participated in the Genesis and Rapid Intensification Processes (GRIP) experiment in August and September of 2010, collecting a large volume of data in several tropical systems, including Hurricanes Earl and Karl. Additional measurements of tropical cyclone have been made by APR-2 in experiments prior to GRIP (namely, CAMEX-4, NAMMA, TC4); Table 1 lists all the APR-2 tropical cyclone observations. The APR-2 observations consist of the vertical structure of rain reflectivity at 13.4 and 35.6 GHz, and at both co-polarization and crosspolarization, as well as vertical Doppler measurements and crosswind measurements. APR-2 normally flies on the NASA DC-8 aircraft, as in GRIP, collecting data with a downward looking, cross-track scanning geometry. The scan limits are 25 degrees on either side of the aircraft, resulting in a roughly 10-km swath, depending on the aircraft altitude. Details of the APR-2 observation geometry and performance can be found in Sadowy et al. (2003).The multiparameter nature of the APR-2 measurements makes the collection of tropical cyclone measurements valuable for detailed studies of the processes, microphysics and dynamics of tropical cyclones, as well as weaker systems that are associated with tropical cyclone formation. In this paper, we give a brief overview of how the APR-2 data are processed. We also discuss use of the APR-2 cross-track winds to estimate various quantities of interest in in studies of storm intensification. Finally, we show examples of the standard products and derived information.

    Ductal adenocarcinoma is the most common malignant tumor of the pancreas. Despite great efforts in basic and clinical pancreatic cancer research, the prognosis remains poor with an overall 5-year survival rate of less than 5%. Complete surgical resection represents the only curative treatment option and 5-year survival rates of 20-25% can be achieved following curative resection and adjuvant chemotherapy. Although pancreatic surgery is considered one of the most technically demanding and challenging procedures, there has been constant progress in surgical techniques and advances in perioperative care with a modern interdisciplinary approach including anesthesiology, oncology, radiology and nursing. This has reduced morbidity and especially mortality rates in high-volume centers. Among extended resection procedures multivisceral and venous resections are technically feasible and should be considered if a complete tumor resection can be achieved. Multimodal regimens have shown promising results, however, only adjuvant chemotherapy is supported by solid evidence from randomized controlled trials. (orig.) [German] Das duktale Adenokarzinom ist der haeufigste maligne Pankreastumor. Trotz intensiver Anstrengungen auf dem Gebiet der Pankreasforschung konnte die Gesamtprognose in den vergangenen Jahren nicht entscheidend verbessert werden. Die einzige potenziell kurative Therapie ist die chirurgische Resektion. In Kombination mit einer adjuvanten Chemotherapie liegen die 5-Jahres-Ueberlebensraten aktuell bei 20-25%. Dank kontinuierlicher Weiterentwicklung der chirurgischen Operationstechnik und Verbesserungen der perioperativen Versorgung der Patienten mit einer engen interdisziplinaeren Zusammenarbeit (Chirurgie, Anaesthesie, Onkologie, Radiologie und Pflege) konnten die perioperative Morbiditaets- und Mortalitaetsraten in den vergangenen Jahren deutlich gesenkt werden. Unter den erweiterten Resektionsverfahren sind Venen- oder multiviszerale Resektionen technisch sicher

    In 1931, Maurice Coelst, M.D. from Brussels started the publication of the first international journal of plastic surgery ever published: the Revue de Chirurgie Plastique (1931-1934), which eventually became the Revue de Chirurgie Structive (1935-1938). In 1936, he established the first European Society of Structive Surgery, which held its first congress in Brussels. Further congresses were held in London in 1937 and in Milan in 1938. It is the collaboration and the participation of British plastic surgeons in this Society, this journal, and these meetings that I want to stress, because I am firmly convinced that these documents fill a gap in the history of Plastic Surgery in Great Britain, since--as far as I know--no detailed information concerning this period was ever published in Plastic Surgery literature.

    Introduction Cette étude a pour objectif de décrire la pratique anesthésique dans un pays à faible revenu et où le plateau technique anesthésique est moins équipé. Méthodes Une étude descriptive transversale a été menée durant l'année 2013. L'enquête a concerné les pratiques anesthésiques, les indications chirurgicales et les caractéristiques des malades. L'encodage et l'analyse des données ont été réalisées grâce aux logiciels Epi Info 3.5.3 et Excel 2010. Résultats Nous avons enregistré 2358 patients dont l’âge médian était de 29 + 15 ans, avec 81,5% âgés de 11 à 50 ans. Parmi eux, 67,3% des malades étaient du sexe féminin. Dans ensemble, 62,5% de ces patients étaient pris en charge pour les interventions programmées. L’évaluation du risque anesthésique a montré que 91,9% des patients étaient de la classe ASA I et II. La chirurgie la plus pratiquée était viscérale (46,7%) suivie de la chirurgie gynéco-obstétricale (29,2%). Les différents types d'anesthésie étaient les suivants: anesthésie générale (87,6%), locorégionale (11,8%) et combinée (0,6%). Conclusion La pratique anesthésique dans la population d’étude était dominée par l'anesthésie générale. Les malades étaient au trois quart de sexe féminin et de la classe ASA I et II. Les résultats de cette étude indiquent la nécessité d’évaluer l'issue de cette pratique. La pratique anesthésique à Lubumbashi est tributaire du plateau technique, des compétences du personnel et de l'acceptabilité du type d'anesthésie par les patients. PMID:26523180

    Georges Mareschal born in 1658 was the son of an Irish gentleman serving in the army of Louis XIII: John Marshall ennobled after the battle of Rocroi (1643) with a francisation of his name. He came to Paris in 1677 and worked with a master-surgeon: Le Breton. He went at the Charité hospital in 1684, was received master-surgeon in 1688 and became there chief-surgeon in 1692. He modified and improved lithotomy. After having operated several personalities and king Louis XIV he became his first surgeon in 1703, later "Maître d'Hôtel" in 1706 and was finally ennobled in 1707. He visited regularly sick people belonging to all classes of society in the Versailles area and played a part in the "poisons affair" in 1712. He remained the First Surgeon of Louis XV and received the cross of Saint-Michel order in 1723. He created with La Peyronie a School of Surgery in Paris officialized by patent letters in 1726. With the help of the same collaborator he founded in 1731 the "SociétéAcademique des chirurgiens de Paris" which will become in 1748 the "Académie Royale de Chirurgie" after his death and that of La Peyronie who had been nominated himself First Surgeon.

    The primary contributors to the total occupational radiation exposure in operating nuclear power plants are operation and maintenance activities during refueling outages. The Advanced Power Reactor 1400 (APR1400) includes a number of design improvements and plans to utilize advanced maintenance methods and robotics to minimize the annual collective dose. The major radiation exposure reduction features implemented in APR1400 are a permanent refueling pool seal, quick opening transfer tube blind flange, improved hydrogen peroxide injection at shutdown, improved permanent steam generator work platforms, and more effective temporary shielding. The estimated average annual occupational radiation exposure for APR1400 based on the reference plant experience and an engineering judgment is determined to be in the order of 0.4 man-Sv, which is well within the design goal of 1 man-Sv. The basis of this average annual occupational radiation exposure estimation is an eighteen (18) month fuel cycle with maintenance performed to steam generators and reactor coolant pumps during refueling outage. The outage duration is assumed to be 28 days. The outage work is to be performed on a 24 hour per day basis, seven (7) days a week with overlapping twelve (12) hour work shifts. The occupational radiation exposure for APR 1400 is also determined by an alternate method which consists of estimating radiation exposures expected for the major activities during the refueling outage. The major outage activities that cause the majority of the total radiation exposure during refueling outage such as fuel handling, reactor coolant pump maintenance, steam generator inspection and maintenance, reactor vessel head area maintenance, decontamination, and ICI and instrumentation maintenance activities are evaluated at a task level. The calculated value using this method is in close agreement with the value of 0.4 man-Sv, that has been determined based on the experience and engineering judgement

  5. Les masques de la masculinité dans le recours à la chirurgie esthétique

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Depuis la fin des années 1990, un nombre croissant de Canadiens ont recours à la chirurgie esthétique comme véritable projet corporel. Un problème sociologique central émerge de ce recours massif. Pourquoi une pratique traditionnellement féminine devient-elle une pratique hautement signifiante pour ces Canadiens? La chirurgie plastique comme pratique culturelle équivaut à une mesure physique de l’évolution des pouvoirs entre les genres dans des pays comme le Canada. En outre, elle sert d’indicateur corporel de la manière dont les hommes vivent la crise actuelle de la masculinité. A la suite de Douglas (1970 ou Sontag (1991, le bouleversement normatif des corps, leurs modifications et leurs représentations publiques sont, en effet, des mesures corporelles des changements des relations de pouvoir entre hommes et femmes. Ces évolutions au Canada déstabilisent réellement les modèles de masculinité hégémonique, et sont directement observables à travers les modifications à même la peau de ces hommes. Ces recours chirurgicaux permettent de révéler les doutes, l’anxiété et l’anomie qui parsèment les cultures contemporaines. Ils redéfinissent les formes de ce travail corporel traditionnellement féminin. Il s’agit donc d’analyser comment les corps masculins modifiés par la chirurgie constituent une mesure aiguë du genre et un révélateur d’identités dans les sociétés comme le Canada.

    Natto is a traditional Japanese food made from soybeans fermented by natto starter strains of Bacillus subtilis natto. It has been suggested that extracellular protease activity released by the bacteria are involved in the production of poly-γ-glutamate (γ-PGA) during natto fermentation. One of the natto starters, strain r22, possesses at least seven genes, each of which encoded an extracellular protease orthologous to its counterpart in B. subtilis 168, aprE, bpr, epr, mpr, nprE, vpr, and wprA, but it was found to lack nprB. Inactivating the aprE ortholog alone resulted in a severe decrease in γ-PGA production and in the total extracellular protease activity. The defect in γ-PGA production of the mutant lacking the aprE ortholog was complemented when the medium was supplemented with sufficient glutamate. These results suggest that the alkaline serine protease encoded by aprE plays an indispensable role in supplying materials to produce γ-PGA. On the other hand, simultaneous inactivation of all the protease genes except for aprE did not significantly affect either γ-PGA production or total protease activity.

    An EDF worker potentially exposed to high-intensity 50 Hz magnetic fields had a cardiac defibrillator implanted. Theoretically its operation could be disturbed by magnetic field exposure at work. We use this case study to present an approach to evaluating work safety and the worker's fitness in such situations. The protocol consisted of measuring the magnetic field at the different places where the worker performed his job duties, in his presence, and simultaneously monitoring the operation of the device. The Medtronic device was programmed in bipolar mode. Throughout the workplace, the maximal magnetic field intensity measured at the device level was 650 {mu}T. No dysfunction was recorded in bipolar mode. Following these measurements and device controls, the worker was declared fit and resumed his previous job. Two years later, no incident has been reported. (authors)

    Metastases are the most frequent tumors of the heart even though they seldom are recognized. Most primary cardiac tumors are benign. The main role of imaging is to differentiate a cardiac tumor from thrombus and rare pseudo-tumors: tuberculoma, hydatid cyst. Echocardiography is the fist line imaging technique to detect cardiac tumors, but CT and MRl arc useful for further characterization and differential diagnosis. Myxoma of the left atrium is the most frequent benign cardiac tumor. It usually is pedunculated and sometimes calcified. Sarcoma is the most frequent primary malignant tumor and usually presents as a sessile infiltrative tumor. Lymphoma and metastases are usually recognized by the presence of known tumor elsewhere of by characteristic direct contiguous involvement. Diagnosing primary and secondary pericardial tumors often is difficult. Imaging is valuable for diagnosis, characterization, pre-surgical evaluation and follow-up. (author)

    In 1996, a multicenter randomized study comparing after breast-conservative surgery. sequential vs concurrent adjuvant chemotherapy (CT) with radiation therapy (RT) was initiated (ARCOSEIN study). Seven hundred sixteen patients were included in this trial. After a median follow-up of 6.7 (4.3 -9) years, we decided to prospectively evaluate the late effects of these two strategies. Patients and methods - A total of 297 patients were asked to follow-up from the five larger including institutions. Seventy-two percent (214 patients) were eligible for late toxicity. After breast-conserving surgery with axillary dissection, patients were treated either with sequential treatment with CT first followed by RT (arm A) or CT administered concurrently with RT (arm B). In all patients, CT regimen combined mitoxantrone (12 mg/m{sup 2}). 5-FU (500 mg/m{sup 2}), and cyclophosphamide (500 mg/m{sup 2}), 6 cycles (day 1-day 21). In arm B, patients received concurrently the first 3 cycles of CT with RT. In arm A, RT started 3 to 5 weeks after the 6. cycle of CT. Conventional RT was delivered to the whole breast using a 2 Gy-fraction protocol to a total dose of 50 Gy ({+-} boost to the primary tumour bed). The assessment of toxicity was blinded to treatment and was graded by the radiation oncologist according to the LENT-SOMA scale. Skin pigmentation was also evaluated using a personal 5-points scoring system (excellent, good, moderate, poor, very poor). Results - Among the 214 evaluated patients, 107 were treated in each arm. The two populations were homogeneous for patients', tumors' and treatment characteristics. Subcutaneous fibrosis (SF), telangiectasia (T), skin pigmentation (SP), and breast atrophy (BA) were significantly increased in arm B. Twenty patients experienced grade superior or equal to 2 (SF) in arm B vs five in arm A (P 0.003). Twenty-five and seven patients showed grade superior or equal to 2 (T) in ann B and A, respectively (P = 0.001). Forty-four and twenty patients showed grade superior or equal to 2 (BA) in arm B and A, respectively (P 0.0006). Thirty patients experienced grade superior or equal to 3 (SP) in arm B vs fifteen in arm A (P= 0.02). No statistical difference was observed between the two arms concerning grade superior or equal to 2 pain, breast oedema and lymphedema. No deaths were caused by late toxicity. Conclusion - Following breast conserving surgery, the concurrent use of CT with RT is significantly associated with an increase incidence of grade 2 or greater late side effects. (author)

    Neo-adjuvant chemoradiotherapy is the gold standard of the treatment of advanced oesophageal squamous cell carcinoma. The role of surgery L. chemoradiotherapy is still debated. Feasibility of curative resection depends on dose of radiotherapy, morbi-mortality rates, and nutrition status at the end of the protocol especially for non-responders patients. Adding surgery to radio-chemotherapy improves local tumour control but does not increase overall survival of patients with advanced oesophageal squamous cell carcinoma. According to the two randomized trials published on the subject, surgery is not recommended after chemoradiotherapy for responders. Recommendations of French National Thesaurus are: exclusive chemoradiotherapy as reference, oesophagectomy for residual tumour as alternative for operable patients. Surgery may be proposed for selected non-responders patients and some complete pathology response in expert center. (author)

    Brookhaven National Laboratory (BNL) assisted the Korea Institute of Nuclear Safety (KINS) in reviewing the Level 2 Probabilistic Safety Assessment (PSA) of the APR+ Advanced Pressurized Water Reactor (PWR) prepared by the Korea Hydro & Nuclear Power Co., Ltd (KHNP) and KEPCO Engineering & Construction Co., Inc. (KEPCO-E&C). The work described in this report involves a review of the APR+ Level 2 PSA submittal [Ref. 1]. The PSA and, therefore, the review is limited to consideration of accidents initiated by internal events. As part of the review process, the review team also developed three sets of Requests for Additional Information (RAIs). These RAIs were provided to KHNP and KEPCO-E&C for their evaluation and response. This final detailed report documents the review findings for each technical element of the PSA and includes consideration of all of the RAIs made by the reviewers as well as the associated responses. This final report was preceded by an interim report [Ref. 2] that focused on identifying important issues regarding the PSA. In addition, a final meeting on the project was held at BNL on November 21-22, 2011, where BNL and KINS reviewers discussed their preliminary review findings with KHNP and KEPCO-E&C staffs. Additional information obtained during this final meeting was also used to inform the review findings of this final report. The review focused not only on the robustness of the APR+ design to withstand severe accidents, but also on the capability and acceptability of the Level 2 PSA in terms of level of detail and completeness. The Korean nuclear regulatory authorities will decide whether the PSA is acceptable and the BNL review team is providing its comments for KINS consideration. Section 2.0 provides the basis for the BNL review. Section 3.0 presents the review of each technical element of the PSA. Conclusions and a summary are presented in Section 4.0. Section 5.0 contains the references.

    Design certification applications (DCAs) submitted pursuant to 10 CFR Part 52 contain two tiers of information, Tier 1 and Tier 2. Tier 1 contains information that is to be certified through rulemaking, and includes the inspections, tests, analyses, and acceptance criteria (ITAAC). Tier 2 contains more detailed information and is the source for information included in Tier1. DC applicants have developed the ITAAC with their own format and contents. This has caused the ineffectiveness of the review process by Nuclear Regulatory Commission (NRC) at the design certification stage. Standardizing the format and content of Tier 1 and ITAAC will achieve greater efficiency and effectiveness for Tier 1 and ITAAC development and NRC review, and for ITAAC implementation and verification. NRC provided the proposed standardized ITAAC for APR1400, and KHNP is considering the application of the proposed ITAAC. The strategy for application of the NRC proposed standardized ITAAC to the APR1400 design certification is now under developing, and a meeting with NRC to review the NRC proposed standardized ITAAC is expected to be held in the near future. In this review process, establishment of industry position on the NRC proposed standardized ITAAC is very important. The support from NEI and US industry is expected to be gained.

    Control Element Drive Mechanism (CEDM) is the device that controls the reactor power by driving and holding of Extension Shaft Assembly (ESA) and Control Element Assembly (CEA). CEDM is operated by applying localized magnetic flux fields which activate parts made of magnetic material which are internal to the pressure boundary. Driving and holding of the ESA and CEA occur when power is sequentially applied to the series of the CEDM electrical coils external to the pressure housing. Because CEDM is operated by electromagnetic force, it is important to evaluate an electromagnetic characteristic of the CEDM. In this study, the electromagnetic analysis of the APR1400 CEDM was performed to evaluate the electromagnetic characteristic of CEDM in holding and withdrawal condition

    Turbine Load Rejection event is one of the Performance Related Design Basis Event (PRDBE) that can be stabilized using plant control systems without any safety system actuation. The initiation of the event is turbine load rejection from 100% to 5% in 0.019 seconds. The NSSS control systems of APR1400 is composed of the Power Control System (PCS) and the Process-Component Control System (P-CCS). The PCS includes Reactor Regulating System (RRS), Reactor Power Cutback System (RPCS) and Digital Rod Control System (DRCS). The P-CCS includes the Pressurizer Pressure Control System (PPCS), the Pressurizer Level Control System (PLCS), the Feedwater Control System (FWCS) and the Steam Bypass Control System (SBCS). Turbine load rejection results in the increase of secondary pressure due to sudden blocking of steam flow to turbine. Then the Reactor Coolant System (RCS) cooling through steam generators is decreased rapidly and the RCS temperature will be increased. Turbine load rejection is a typical event to test NSSS control systems since it requires the automatic response of all major NSSS control systems. It is shown that the NSSS control systems of APR1400 have the capability to stabilize the plant without any safety system actuation for turbine load rejection event. This analysis results show that SPACE code has the capability to analyze the turbine load rejection event. However, further validation is necessary for other PRDBEs such as Two Main Feedwater Pumps Trip, Turbine Load Step Change and Turbine Load Ramp Down (5%/min) to verify the capability of SPACE for the full range of performance analyses.

    Full Text Available The Fukushima Dai-ichi nuclear power plant accident shows that an extreme natural disaster can prevent the proper restoration of electric power for several days, so-called extended SBO. In Korea, the government and industry performed comprehensive special safety inspections on all domestic nuclear power plants against beyond design bases external events. One of the safety improvement action items related to the extended SBO is installation of external water injection provision and equipment to RCS and SG. In this paper, the extended SBO coping capability of APR1400 is examined using MAAP4 to assess the effectiveness of the external water injection strategy. Results show that an external injection into SG is applicable to mitigate an extended SBO scenario. However, an external injection into RCS is only effective when RCS depressurization capacity is sufficiently provided in case of high pressure scenarios. Based on the above results, the technical basis of external injection strategy will be reflected on development of revised severe accident management guideline.

The emergency core cooling system (ECC) of the APR+ is different with that of the APR-1400, though the APR+ adopted a direct vessel injection (DVI) system which is the same design features of the APR-14000. The main difference of the DVI+ is the emergency core barrel duct (ECBD) which is designed to increase the amount of the injection water to the core region. The performance of the DVI system has been an important issues for past decades, and many researchers have studied the related thermal-hydraulic technical issues such as the ECC bypass fraction, the steam condensation effect, temperature distribution, sub-cooling margin, and etc. However, the previous research cannot be directly applicable to the APR+ owing to the unique features of the DVI+. The current study will elaborate on the experimental evaluation of the direct ECC bypass performance. The 1/5 ECC bypass test facility which is designed with a linearly reduced 1/5 scale referring to the APR+ was used to investigate the effect of the DVI+ injection nozzle location and the broken cold leg velocity on the direct ECC bypass fraction. However, air is used as a working fluid to simulate the steam flow induced from the broken cold leg, and thus, the direct contact condensation effect is not considered in this study. Experimental study for the direct ECC bypass phenomena has been carryout out with various the injection mode and air velocity conditions. The tests were performed in the 1/5 scale ECC bypass test facility, and the test condition was defined using a scaling law referring to the APR+ reactor. Test results showed that the direct ECC bypass fraction was greatly enhanced compared with the reference test (w/o ECBD)

    APR 1400 is a PWR (Pressurized Water Reactor) with rated power of 3983 MWth and 241 assemblies. Recently, demand for extremely longer cycle up to 24 months is increasing with challenge of higher critical boron concentration (CBC). In this paper, assembly design method of selecting Gd-rods is introduced to reduce CBC. The purpose of the method is to lower the critical boron concentration of the preliminary core loading pattern (PLP), and consequently to achieve more negative or less positive moderator temperature coefficient (MTC). In this method, both the ratio of the number of low-Gd rod to the number of high-Gd rod (r) and assembly average Gd wt% (w) are the decision variables. The target function is the amount of soluble boron concentration reduction, which can be converted to Δk{sub TARGET}. A set of new designed fuel assembly satisfies an objective function, min [f=∑{sub i}(Δk{sub FA}−Δk{sub i})], and enables a final loading pattern to reach a target CBC. The constraints required to determine a set of Δk are physically realizable pair, (r,w), and the sum of Δk of new designed assemblies as close to Δk{sub TARGET} as possible. New Gd-bearing assemblies selected based on valid pairs of (r,w) are replaced with existing assemblies in a PLP. This design methodology is applied to Shin-Kori Unit 3 Cycle 1 used as a reference model. CASMO-3/MASTER code is used for depletion calculation. CASMO-3/MASTER calculations with new designed assemblies produce lower CBC than the expected CBC, proving that the proposed method works successful.

    While it is required to include the anticipated Occupational Radiation Exposure (ORE) in the DC application, the ORE data for APR1400 is not available, since the first APR1400 is under construction in Korea. Therefore, this study performs the uncertainty analysis to estimate the expected ORE dose for APR1400 DC using the experience data from the operating plant in Korea based on the methodology specified in NRC Regulatory Guide(RG) 8.19. According to the results, if the design improvements are taken into account, it is found that the median value of APR1400 ORE dose, even for the case of 95 percentile value is within the design target of 1 man-Sv.

    This study aimed to investigate the expression of PP2A/PR65 protein in ameloblastoma and the molecular mechanisms underlying the regulation of PP2A/PR65. The association between PP2A/PR65 and the clinicopathological characteristics of tumor specimens in ameloblastoma were to provide a theoretical basis for the diagnosis, therapy and prognosis of ameloblastoma. Streptavidin-peroxidase (S-P) immunohistochemical staining was used to detect PP2A/Pr65 expression changes in a total of 68 cases of ameloblastoma, six ameloblastic carcinomas, 21 squamous cell carcinomas and seven normal oral mucosas. Western blot was used to analyze PP2A/PR65 protein expression in 15 cases of ameloblastoma and three cases of normal oral mucosa. Of the 68 cases analyzed, four cases were negative, 25 cases were weakly positive, 20 cases were moderately positive and 19 cases were strongly positive. In six cases of ameloblastic carcinoma, three cases were weak positive, one case was positive, two cases were strongly positive and none were negative. In 21 cases of squamous cell carcinomas, three cases were negative, 17 cases were weakly positive, one case was moderately positive and none were strongly positive. Western blot analysis showed that, PP2A/Pr65 protein expression was lower in ameloblastoma tissue compared with normal oral mucosa. Reduced expression of PP2A/PR65 in ameloblastoma compared with normal oral mucosa indicates that PP2A/PR65 is involved in the occurrence and development of ameloblastoma.

    As a part of the Advanced Power Reactor 1400 (APR1400) U. S. Nuclear Regulatory Commission Design Certification (NRC DC) project, we have been investigating Auxiliary Charging Pump (ACP) room heat up. With reference to the design specification of the ACP room, we determined input information and developed a GOTHIC model of the APR1400 ACP room. This calculation model is described herein, and representative results from the calculation are presented as well. The results of the present paper are used to determine the integrity of ACP operating in the accident. APR 1400 GOTHIC model was developed for ACP room heat up calculation. Calculation results confirm that door opening is cooling the room properly. It is found that the difference due to the surface option of heat conductors is insignificant. Based on this result, further studies should be performed to confirm integrity of ACP.

    A echocardiography and a MRI (Magnetic Resonance Imaging) investigation were achieved at 3 months to 7 years after heart transplant in 61 patients among whose 35 were suspected of rejection and 32 have had a myocardial biopsy. The myocardial (T{sub 2}) transversal relaxation time was determined by using an inversion-recovery/spin-echo upon a magnet of 0.5 T. The rejection diagnosis criteria by echography was compared with that of a anomalistic high value of T{sub 2}: 1. the MRI was positive but the echography not in 5 cases, all having positive biopsies; 2. the echography was positive but the MRI was not in 10 cases among which all the biopsies were negative; 3. the MRI and the echography gave concordant results in 46 cases (7 positives and 39 negatives) among which an agreement with the biopsy results was observed in 91% (20/22) of cases. The 12 patients having a positive MRI have had a new examination at 2 to 15 days after the anti-rejection treatment; the T{sub 2} values got normalized. In conclusion, the determination of the myocardial T{sub 2} by means of a `black blood` MRI sequence appears to be superior to an echocardiography in detecting the rejections after heart transplant and could be utilised to evaluate the efficiency of anti-rejection treatment

    The operators perform the paper-based procedures in analog-based conventional main control room (MCR) depending on only communications between operators except a procedure controller such as a Shift Supervisor (SS), however in digital-based MCR the operators can confirm the procedures simultaneously in own console when the procedure controller of computerized procedure (CP) opens the CP. The synchronization and a synchronization function between procedure controller and other operators has to be considered to support the function of crew operation. This paper suggests the improved design of crew operation in computerized procedure system of APR1400. This paper suggests the improved design of APR1400 CPS. These improvements can help operators perform the crew procedures more efficiently. And they reduce a burden of communication and misunderstanding of computerized procedures. These improvements can be applied to CPS after human factors engineering verification and validation.

    Safety issue for nuclear power plant is reviewed. One of the main issue is Top Mounted In-core Instrumentation (TM-ICI). TM-ICI has the advantage of the structural integrity on the reactor bottom head during severe accident. This research about adopting the TM-ICI for APR1400 has been performed to have this advantage. Designing the nuclear power plant, safety issue is very important, and TM-ICI is one of the main issue. For the research of the TM-ICI, APR1400 has been reviewed for possibility of the TM-ICI and the results are as follows: The ICI nozzle head penetration shall be located outside of the CEDM nozzles and Two types of CEAs shall be unified into one type.

    This paper is to investigate means of the available gravity makeup after the event to prevent or sustain the core uncovery and fuel failure for the typical advanced power reactor nuclear power plants (APR1400). Unlike the OPR1000 (optimized power reactor 1000 nuclear power plants), the refueling water storage tank of APR1400 cannot be used for gravity makeup since it is located on the bottom of the containment with a lower elevation than the reactor vessel. So, the other means of gravity makeup and their effect on the core uncovery are accounted. The use of the water used for the cask loading pit (CLP) during refueling or the safety injection line filling tank (SIFT), which are not designed for gravity makeup during the event, and safety injection tanks (SITs) are considered as the alternative source of makeup feed. The results show that gravity makeup of a SIT provides a sufficient operator action time for the LORHR with the station black out (SBO) during the mid-loop operation for the APR1400. From the LORHR event analysis, the effective means of gravity makeup for APR1400 to cope with this event concurrent loss of all AC power is determined as the gravity feed using SITs. Other means for gravity makeup using CLP or SIFT, which are not designed to mitigate the LORHR event, are evaluated as not effective to the event due to the large flow resistances and the low elevation head to overcome the system pressure increase during the LORHR. The use of one SIT and two SITs for the LORHR provides the core uncovery times as 3 hr 8 min and 4 hr 32 min extending 1 hr 15 min and 2 hr 38 min from the base case, respectively.

    Many regulatory requirements and recommendations following the Fukushima accident have been issued to cope with the extended station blackout (SBO) by the NRC, INPO, IAEA, ENSREG, WENRA, etc., and the nuclear safety improvement design features of each country have been enhanced to incorporate the lessons learned from the Fukushima accident. There have been many evaluations to cope with the extended loss of alternating current (AC) power (ELAP) event after the Fukushima accident. PWROG has developed the FLEX support guideline (FSG) that provides the guidance to mitigate the consequences of ELAP event based on the FLEX. The FSG is interfaced with emergency operating guidelines (EOGs) and severe accident management guidelines (SAMGs). However, the FSG developed by PWROG is not compatible with EOGs for both OPR1000 and APR1400 NPPs. Therefore, it is necessary to develop an extended station blackout recovery guideline (ESRG) to cope with an extended SBO event utilizing the newly adopted safety improvement design features against Fukushima accident for OPR1000 and APR1400 NPPs. The ESRG is also performed to satisfy all safety functions and to prevent from entering SAMGs during an extended SBO event. Therefore, this ESRG is entirely appropriate to cope with an extended SBO event by utilizing the newly adopted safety improvement design features following Fukushima accident for OPR1000 and APR1400 NPPs. This guideline will be considered in the establishment of accident management planning in near future.

    The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration. © 2012 John Wiley & Sons Ltd.

    In this paper, radiological impacts on human beings during normal execution of the decommissioning operations from the current standard design of EU-APR which has been modified and improved from its original design of APR1400 to comply with EUR, are evaluated. Decommissioning is the final phase in the life cycle of a nuclear installation, covering all activities from shutdown and removal of fissile material to environmental restoration of the site. According to article 5.4 specified in chapter 2.20 of European Utility Requirements (EUR), all relevant radiological impacts on human being should be considered during the environmental assessment of decommissioning, including external exposure from direct radiation of plant and other radiation sources, and internal exposure due to inhalation and ingestion. In this paper, radiological impacts on human beings during normal circumstances of the decommissioning operation were evaluated from the current standard design of EU-APR based on the simple transport model and practical generic methodology for assessing the radiological impact provided by IAEA. The results of dose assessment fulfilled the dose limit for all scenarios.

    Highlights: • A simplified beam element model is constructed based on the real dynamic characteristics of the APR1400. • Time history analysis is performed to calculate the seismic responses of the structures. • Large deformations can be observed at the in-phase mode of reactor vessel and core support barrel. - Abstract: Structural integrity is the first priority in the design of nuclear reactor internal structures. In particular, nuclear reactor internals should be designed to endure external forces, such as those due to earthquakes. Many researchers have performed finite element analyses to meet these design requirements. Generally, a seismic analysis model should reflect the dynamic characteristics of the target system. However, seismic analysis based on the finite element method requires long computation times as well as huge storage space. In this research, a beam element model was developed and confirmed based on the real dynamic characteristics of an advanced pressurized water nuclear reactor 1400 (APR1400) system. That verification process enhances the accuracy of the finite element analysis using the beam elements, remarkably. Also, the beam element model reduces seismic analysis costs. Therefore, the beam element model was used to perform the seismic analysis. Then, the safety of the APR1400 was assessed based on a seismic analysis of the time history responses of its structures. Thus, efficient, accurate seismic analysis was demonstrated using the proposed beam element model.

    In this paper for containment performance analysis, the containment pressurization analysis is performed and thermo-hydraulic response analysis of containment structure is carried out to provide basic understanding of containment transient states under a severe accident sequence. Especially, in EU-APR1400 design, to reduce containment pressure and temperature, Severe Accident Containment Spray System (SACSS) is designed to be actuated automatically when Core Exit Temperature (CET) reaches 922 K (649 .deg. C). The containment performance analysis was carried on LBLOCA sequence for EU-APR1400 with SACSS through MAAP code. If SACSS is actuated when CET reaches 922 K (649 .deg. C) , the containment pressure and temperature decrease to a sufficient low level. The predicted atmospheric pressure of containment will not exceed the ultimate pressure capacity (UPC) and have a sufficient margin to it even though the UPC of the reference plant (Shin-Kori Units 3 and 4) is used instead because the UPC calculation for EU-APR1400 has not been completed. The largest load on the containment by LBLOCA is estimated at 306.1 kPa. Thus the margin to UPC is estimated to be 330 % in comparison with 1.329 MPa as UPC for the reference plant.

    Hot process water is pumped from the plant process to the cooling towers. Heat is rejected through evaporation of the process water, interacting with ambient air blown upward by fans.. Plumes generated from exit ports of the cooling tower may have adverse effects on the environment, such as deposition of cooling tower drift release, fogging, icing, shadowing, and ground-level temperature and humidity increase. These kinds of environmental impact of the cooling tower are linked closely with the dispersion of the cooling tower plumes. In this respect, predicting the behavior of the plumes has become one of the most important issues in the environmental assessments of the cooling towers. The SACTI (seasonal/annual cooling tower impact) model is an analytical tool to predict the environmental effect of cooling tower, which was developed by Argonne National Laboratory and University of Illinois with support from EPRI (electric power research institute). The initial version of SACTI has been widely used to assess the environmental effect of cooling towers in many industrial fields such as steam power plants and NPPs. Guo et. al. investigated impact of heat rejection and cooling tower height on plume dispersion using the SACTI model, for the purpose of the future construction of inland NPPs. They found that increasing cooling tower height decreases the plume length and height frequencies. Their simulation results showed that the increase in heat rejection increases the plum radius frequency. The APR1400DC is an advanced light water reactor developed for the purpose of NRC-DC (design certification). The cooling towers for APR1400DC UHS consist of two linear mechanical draft cooling towers (LMDCTs). The LMDCT for APR1400DC UHS is conceptually designed because the plant site has not been decided yet. In the present study, the dependency of plume dispersion on the number of cooling towers is investigated using SACTI-2-beta, for predicting annual environmental effect of APR

    EU-APR, modified and improved from its original design of APR1400, has been developed to comply with European Utility Requirements (EUR) and nuclear design requirements of the European countries. In EU-APR, Severe Accident Mitigation Systems are dedicated to providing an independent defense line from that of Engineered Safety Feature (ESF) and Diverse Safety Feature (DSF). They consist of Emergency Reactor Depressurization System (ERDS), Passive Ex-vessel corium retaining and Cooling System (PECS), Severe Accident Containment Spray System (SACSS), Hydrogen Mitigation System (HMS) and Containment Filtered Vent System (CFVS). The PECS, so called core catcher, was introduced to prevent the Molten Core Concrete Interaction (MCCI) after Reactor Vessel (RV) failure. The PECS has experienced a lot of changes from its original design. Recently, the most significant change was that as a SM, limestone concrete is installed on PECS's body wall instead of previous sacrificial material rich in Fe{sub 2}O{sub 3}. The main reason of this design change is to overcome the issue that the sacrificial material is ablated rather too fast when reacting with corium that contains a large fraction of Zr metal. Other changes in the geometry of PECS's wall and downcomer design are considered as minor ones. In this paper, the comparison of ablation rates between previous SM and limestone concrete is carried out using MAAP5 code with respective MCCI model according to the material. In this paper, major improvements of MAAP5 model for PECS in EU-APR are presented and the evaluation of ablation rate for the previous SM model and the new LC model is carried out by means of ablation depths with LBLOCA sequence. Two models have respective unique ablation process. The ablation of LC model proceeds at a constant rate regardless of water while the ablation of SM model proceeds at a faster rate before the arrival of cooling water for corium and SM mixture. The change of sacrificial material

    After the Fukushima accident, EPRI has developed the MAAP (Modular Accident Analysis Program) version 5 that is expected to make up the limitation of MAAP4, that is to say, the appropriateness of the model for the severe accident phenomena and the applicability to the phenomena in the spent fuel pool and the halfloop operation. Up to now, the newest version of MAAP is 5.0.2 (Build 5020000) that was released officially in December, 2013. In addition to this, it is expected that MAAP 5.0.3 version will be published sooner or later. As a kind of post-Fukushima measures, KHNP is developing the probabilistic safety assessment (PSA) and severe accident management guideline (SAMG) for low power and shutdown (LPSD) mode and MAAP 5.0.2 should be used in these projects as a major analysis program. So, first of all, it is necessary that the parameter file for domestic NPP should be upgraded as current Ver. MAAP4 to Ver. MAAP 5.0.2. KHNP has developed the draft version of parameter file for APR1400 type NPP and is being upgraded continuously. The Engineering Safety Features (ESF) model is one of the unique features of MAAP. In this study, we try to share the general information of the MAAP ESF model and the specific characteristics of APR1400 ESF model based on the newly developed MAAP 5.0.2 parameter file. Currently, while developing the LPSD PSA and LPSD SAMG as a kind of post-Fukushima measures, KHNP have the plan in order to upgrade the old parameter file based on MAAP4 to that based on MAAP5.0.2 for all domestic nuclear power plants. And, as the first effort, we are developing the MAAP 5.0.2 parameter file for APR1400 type NPP. In this study, we tried to develop the more accurate and reasonable ESF model of APR1400. In this process, we can find the distinctions and characteristics of specific ESF model and generalized ESF model of MAAP5.0.2. Also, we can eliminate the confusing concepts existed in the two models. So, it is judged that the newly developed MAAP5

    To increase and diversify the export marker of the Korean nuclear reactor design, we developed the Eu- APR1400 reactor design based on the APR1400 reactor design, satisfying the European nuclear design requirements including the European Utility Requirements (EUR) and the Finnish requirements of YVL. As recommended by both requirements, the so called core-catcher molten core ex-vessel cooling facility was developed to manage a severe accident at the Eu-APR1400 reactor involving a core meltdown and to mitigate its consequences. Usually, sacrificial material (SM), which controls the melt properties and modifies melt conditions favorable to corium retention, can be employed to protect the core catcher body from the molten core and increase its cooling capability. The EPR reactor design (by Areva, France) core catcher consists of the initial corium retention space, the transportation channel and the wide spreading room for core melt cooling. The EPR used two kinds of SM to protect the initial core retention space from core melt and to spread the core melt across the wide spreading room using the different compositions. The VVER (Russia) ensures melt localization in a water-cooled vessel located directly beneath the reactor. SM is used to remove the thermal focusing effect by the layer inversion process between metallic and oxidic melts. The functional requirements for the SM determined for the present core catcher are (1) melting spreading improvement, (2) focusing effect prevention, (3) hydrogen explosion prevention, (4) FP (fission product) release decreasing, and (5) melt recriticality exclusion. The rest of the paper is organized as follows. The next section provides detailed descriptions of the composition of the present SM, which satisfies its functional requirements. Following this, the manufacturing process of the SM is presented

    There are so many changes in the models such as the Lower head plenum model, Debris Coolability model, Molten Core Concrete Interaction, and the analysis scope is enlarged to the phenomena in the spent fuel pool and the half-loop operation. As a kind of post-Fukushima measures, KHNP is developing the probabilistic safety assessment (PSA) and severe accident management guideline (SAMG) for low power and shutdown (LPSD) mode and MAAP 5.0.2 should be used in these projects as a major analysis program. So, first of all, it is necessary that the parameter file for domestic NPP should be upgraded as current Ver. MAAP4 to Ver. MAAP 5.0.2. KHNP developed the draft version of parameter file for APR1400 type NPP and is being tested for some basic severe accident sequence. In this study, we try to share the information for newly developed parameter and compare the analysis results using MAAP 5.0.2 with previous results using MAAP4. Currently, while developing the LPSD PSA and LPSD SAMG as a kind of post-Fukushima measures, KHNP have the plan in order to upgrade the old parameter file based on MAAP4 to that based on MAAP5.0.2 for all domestic nuclear power plants. As the first effort, we developed the MAAP 5.0.2 parameter file for APR1400 type NPP. In this study, we can find that the newly developed MAAP5.0.2 parameter file for domestic APR1400 type is appropriate for actual analysis. But, as a draft version, it is judged that it should be revised through the sensitivity studies, especially focused on the newly introduced models in MAAP 5.0.2.

    The Fukushima Dai-ichi nuclear power plant accident shows that natural disasters such as earthquakes and the subsequent tsunamis can cause station blackout for several days. The electricity required for essential systems during a station blackout is provided from the emergency backup batteries installed at the nuclear power plant. In South Korea, in the event of an extended station blackout, the life of these emergency backup batteries has recently been extended from 8 hours to 24 hours at Shin-Kori 5, 6 and APR1400 for design certification. For a battery life of 24 hours, available safety means system, equipment and procedures are studied and analyzed in their ability to cope with an extended station blackout. A sensitivity study of reactor coolant pump seal leakage is performed to verify how different seal leakages could affect the system. For simulating of extended station blackout scenarios, the best estimate MARS-KS was used. In this paper, an APR1400 RELAP5 input deck was developed for station blackout scenario to analyze operation strategy by manually depressurizing the reactor coolant system through the steam generator's secondary side. Additionally, a sensitivity study was performed on reactor coolant pump seal leakage.

    In this study, the key-way bypass was determined to be - 0.3 %. The steady state condition which is the initial condition for LBLOCA was obtained by MARS-KS calculation. Up to now, it was assumed that the temperature of the upper dome in APR-1400 was close to that of the cold leg. However, it was found that the temperature of the upper head/dome might be a little lower than or similar to that of the hot leg through the evaluation of the detailed design data. Since the higher upper head temperature affects blowdown quenching and peak cladding temperature in the reflood phase, the nodalization for upper head should be modified. In this study, the preliminary sensitivity study of original and modified nodalization for LBLOCA was performed, and the effect of upper head nodalization and temperature was evaluated qualitatively. In this study, the preliminary sensitivity study of original and modified nodalization for upper head in APR-1400 was performed, and the effect of upper head nodalization and temperature on LBLOCA PCT was evaluated qualitatively. Through the transient calculation, it was confirmed that the upper head temperature affects the water inventory in the upper head at the early stage of LBLOCA so it does the blowdown quenching and following reflood PCT significantly. The results in this study were caused by very conservative upper head temperature determination.

    The thermal hydraulic and electric capability of the RCP test facility (RCPTF) covers up to 18.5 MPa, 343 .deg. C, 11.7 m{sup 3}/s, and 14.0 MW in the design pressure, temperature, flow rate, and the maximum electric power, respectively. In 2013, commissioning test had been performed to verify its designed capability, followed by several modifications in the RCPTF including signal processing and control logic to enhance verification and evaluation capability of the RCP performance. After finishing the commissioning and modification of the RCPTF, type test for the new-type RCP had been performed successfully. In this paper, several technical issues developed in the 2013 and the type test's method and results will be described. In the present paper, the technical activities for the development of the verification test of APR1400's RCP are described. KAERI has completed the full set of technology development, prerequisite for the RCP verification test, and now on the way to perform a test for the sealing capacity of the seal assembly during the Station Block Out (SBO) condition of APR1400.

    Na-APR-1(M74) is an aspartic protease that is rendered enzymatically inactive by site-directed mutagenesis and is a candidate antigen component in the Human Hookworm Vaccine. The mutant protease exerts vaccine efficacy by inducing antibodies that neutralize the enzymatic activity of wild type enzyme (Na-APR-1wt) in the gut of the hookworm, thereby depriving the worm of its ability to digest its blood meal. Previously, canines immunized with Na-APR-1(M74) and challenged with Ancylostoma caninum were partially protected against hookworm challenge infection, especially from the loss in hemoglobin observed in control canines and canine immunoglobulin (Ig) G raised against Na-APR-1 was shown to inhibit the enzymatic activity of Na-APR-1 wt in vitro, thereby providing proof of concept of Na-APR-1(M74) as a vaccine antigen. The mutated version, Na-APR-1(M74), was then expressed at the cGMP level using a Nicotiana benthamiana expression system (Fraunhofer, CMB, Delaware, MD), formulated with Alhydrogel®, and used to immunize mice in a dose-ranging study to explore the enzyme-neutralizing capacity of the resulting anti- Na-APR-1(M74) IgG. As little as 0.99 μg of recombinant Na-APR-1(M74) could induce anti Na-APR-1(M74) IgG in mice that were capable of inhibiting Na-APR-1w t-mediated digestion of a peptide substrate by 89%. In the absence of enzymatic activity of Na-APR-1(M74) as a surrogate marker of protein functionality, we developed an assay based on the binding of a quenched fluorescence-labeled inhibitor of aspartic proteases, BODIPY-FL pepstatin A (BDP). Binding of BDP in the active site of Na-APR-1 wt was demonstrated by inhibition of enzymatic activity, and competitive binding with unlabelled pepstatin A. BDP also bound to Na-APR-1(M74) which was assessed by fluorescence polarization, but with an ∼ 50-fold reduction in the dissociation constant. Taken together, these assays comprise a "toolbox" that could be useful for the analyses of Na-APR-1(M74) as it

  13. Molecular analysis of the distribution and phylogeny of dissimilatory adenosine-5'-phosphosulfate reductase-encoding genes (aprBA) among sulfur-oxidizing prokaryotes.

    Dissimilatory adenosine-5'-phosphosulfate (APS) reductase (AprBA) is a key enzyme of the dissimilatory sulfate-reduction pathway. Homologues have been found in photo- and chemotrophic sulfur-oxidizing prokaryotes (SOP), in which they are postulated to operate in the reverse direction, oxidizing sulfite to APS. Newly developed PCR assays allowed the amplification of 92-93 % (2.1-2.3 kb) of the APS reductase locus aprBA. PCR-based screening of 116 taxonomically divergent SOP reference strains revealed a distribution of aprBA restricted to photo- and chemotrophs with strict anaerobic or at least facultative anaerobic lifestyles, including Chlorobiaceae, Chromatiaceae, Thiobacillus, Thiothrix and invertebrate symbionts. In the AprBA-based tree, the SOP diverge into two distantly related phylogenetic lineages, Apr lineages I and II, with the proteins of lineage II (Chlorobiaceae and others) in closer affiliation to the enzymes of the sulfate-reducing prokaryotes (SRP). This clustering is discordant with the dissimilatory sulfite reductase (DsrAB) phylogeny and indicates putative lateral aprBA gene transfer from SRP to the respective SOB lineages. In support of lateral gene transfer (LGT), several beta- and gammaproteobacterial species harbour both aprBA homologues, the DsrAB-congruent 'authentic' and the SRP-related, LGT-derived gene loci, while some relatives possess exclusively the SRP-related apr genes as a possible result of resident gene displacement by the xenologue. The two-gene state might be an intermediate in the replacement of the resident essential gene. Collected genome data demonstrate the correlation between the AprBA tree topology and the composition/arrangement of the apr gene loci (occurrence of qmoABC or aprM genes) from SRP and SOP of lineages I and II. The putative functional role of the SRP-related APS reductases in photo- and chemotrophic SOP is discussed.

    wall where a pressure rupture can occur, thus breaching the pressure boundary. This paper focuses on the experimental investigation on the tube ejection failure during a severe accident for the APR1400 ICI penetration, as it is exposed to high temperature of melt and the force exerted by the RCS pressure. An APR1400 ICI penetration specimen was provided by Doosan Heavy Industry and ZrO{sub 2} was used as a prototypic melt. During the interaction of the penetration specimen with the melt, the temperature distributions at the reactor vessel, reactor vessel hole and penetration nozzle were monitored to estimate the weld failure and subsequent tube ejection possibilities. For the verification experiment during a severe accident, the APR1400 ICI penetration specimen was manufactured according to the real manufacturing process with the same materials and dimensions. Zirconium dioxide was used as a simulant of corium melt and interacted with the penetration specimen. The specimen was pressurized up to 2.5 bar during the interaction with melt to induce the tube ejection. The penetration weld was heated up to its melting temperature, and the penetration tube and weld above the reactor vessel surface were eroded severely by the melt. However, even though it was estimated that the weld failure occurred and the reactor vessel with stainless cladding was ablated severely by the melt, the tube ejection phenomenon was not observed and consequently the integrity for the APR1400 ICI penetration was confirmed in the present experimental conditions.

    After the Fukushima accident, EPRI has continuously upgrade the MAAP5 (Modular Accident Analysis Program version 5) that is expected to expand the limitation of MAAP4. As a result of those efforts, the MAAP5.0.2 (Build 5020000) was released officially in December, 2013. Also, in August, 2014, the newest version of MAAP5, MAAP 5.0.3 (Build 5030000), was officially released. The parameter file development is essential for severe accident analysis using MAAP code for specific plant. In 2014, KHNP developed the first draft version of MAAP 5.0.2 parameter file for APR1400 type NPP and had tested for some basic severe accident sequence. And, until now, KHNP has continuously complemented the first draft version of APR1400 type NPP parameter file for MAAP 5.0.2 and 5.0.3. In this study, we analysis the MCCI phenomena using MAAP 5.0.3 version with the 2''n''d draft version of APR1400 parameter file developed by KHNP. The purpose of this study is to compare the major difference in MAAP 5.0.2 and 5.0.3 MCCI model and to verify the appropriateness of the 2''n''d draft version of parameter file. The MCCI phenomena have been controversial issues in the severe accident progression, so there have been great efforts to solve them until now. As the part of these efforts, EPRI published MAAP 5.0.3 version which is known that the 'Lower head plenum model' and the 'MCCI model' was upgraded. KHNP have the plan in order to upgrade the old parameter file based on MAAP4 to that based on MAAP5.0.2 or higher version for all domestic nuclear power plants. So, we have continuously developed the MAAP 5.0.2 and 5.0.3 parameter file for APR1400 type NPP. In this study, we analyzed the MCCI phenomena using MAAP 5.0.3 and 2''n''d draft version parameter file. And we found some insight as belows; (1) The Melt Eruption Model can greatly affect the MCCI progression only in the case of limestone concrete in the wet cavity

    These reports include the licensing issues as follows; the effect of a flow channel gap change, the effect of debris settling, the accuracy of the GF630 flow meter, the effect of bubbles impinging on the bottom nozzle, and the bypass fiber amount. In this paper, the valuation results of the in-vessel downstream effects for the APR1400 were described. In addition, the effect of a flow channel gap change and the bypass fiber amount were evaluated. In-vessel downstream effect tests with a mock-up PLUS7 fuel assembly were performed to confirm that the head losses caused by debris meet the available driving head following a LOCA. All the test results showed lower pressure drops than the available head limits. Therefore, a sufficient driving force is available to maintain an adequate flow rate, and the LTCC capability is adequately maintained in the APR1400. A sensitivity test was conducted to assess the effect of a change in the gap size between the mock-up fuel assembly and the test column. The maximum pressure drop recorded for the test was 19.73 kPa under the re-manufactured condition. This value is larger by 1.6% than the previous test result (19.4 kPa) under the same conditions. As such, changing the gap of the flow path between the mock-up fuel assembly and the test column from the previous manufactured conditions to the re-manufactured conditions is expected to result in a slight increase in the differential pressure. However, this is a negligible amount compared to the test uncertainty value of 25%.

    Summary Les brûlures de la main chez l’enfant constituent une source de séquelles invalidantes. A cet régard, la conservation et la restauration complète de la fonction de la main demeurent le but primordial de la prise en charge. Afin de répertorier les caractéristiques épidémiologiques, cliniques et évolutives des mains brûlées, nous avons réalisé une étude rétrospective étalée sur 4 ans, de janvier 2011 à janvier 2015. Cette étude a permis de colliger les cas de 313 enfants atteints de brûlure de la main vus dans le Centre National des Brulés et de Chirurgie Plastique du CHU Ibn Rochd de Casablanca. La majorité des brûlures touche les enfants de 3 à 6 ans (70% des cas), avec une légère prédominance masculine. La principale cause des brûlures survenant à cet âge est l’ébouillantement. Les brûlures par flamme représentent 33% des cas, celles par électricité 4,5%. Les brûlures chimiques et par contact sont anecdotiques (1 cas chacune). L’accident survient le plus souvent à domicile. Soixante douze pour cent des brûlures ont guéri spontanément. Afin de diminuer l’incidence de ces accidents, une approche préventive faite de sensibilisation et d’éducation devrait faire partie du cursus scolaire. PMID:27777543

    The dissimilatory adenosine-5'-phosphosulfate (APS) reductase (cofactors flavin adenine dinucleotide, FAD, and two [4Fe-4S] centers) catalyzes the transformation of APS to sulfite and AMP in sulfate-reducing prokaryotes (SRP); in sulfur-oxidizing bacteria (SOB) it has been suggested to operate in the reverse direction.

    In this study, calculations have been carried out for a SBO sequence similar to the selected scenario, but a faster one with simple assumptions. Instead, a sensitivity study was carried out to take into account the effects of such differences on the fission product behavior. Probabilistic Safety Assessment (PSA) for Shin-Kori 3·4 nuclear power plants, which are APR1400 type reactors, were reviewed. After all, the representing scenarios were determined to be the sequences with station blackout (SBO), interfacing system LOCA (ISLOCA), and steam generator tube rupture (SGTR), which are similar to those of the U.S.NRC's State-of-the-Art Reactor Consequence Analyses (SOARCA) study. Among those sequences, SBO occupies the largest portion of the risk from severe accidents, and was selected to be analyzed at first about the fission product behavior in the containment. It includes events such as failure of the alternative AC power generator following a blackout event, successful operation of turbine-driven auxiliary feed water (AFW) pump, late recovery of offsite power before containment failure, in-vessel injection and successful actuation of cavity flooding system and spray system, and failure of hydrogen mitigation system. We use MELCOR 1.8.6 with the 35- and 2-cell compartment models of the containment. Since MELCOR does not treat organic iodide, we tried to make the results up by MELCOR-RAIM which is the MELCOR code coupled with RAIM, a stand-alone code developed for evaluation of the iodine behavior. In order to investigate the fission product behavior during a severe accident at APR1400, we have selected the representing scenarios with SBO, ISLOCA and SGTR.

    Digitalized MMI(Man-Machine Interface) including Digital Main Control Room(MCR) and digital I and C system was being applied for SKN 3 and 4 Nuclear Power Plant(NPP) and subsequent APR1400 NPP type. But, operators can not easily find instrument for alarm immediately. Therefore, Alarm system is required to easily find instrument for Alarm. For this implementation, we will plan system design considering design feature without affecting network load and CPU load. We have developed Alarm system link drawing for digital MCR. Operators of the digitalized MCR navigates from their consoles to the drawings related to the plant alarms and their instruments or the operation status. Such method gives cognitive load to the operators having to travel to different locations in finding the related information. Screen Sharing System, which is the fundamental technique for Drawing Interconnection Alarm System is close to completion, and it should be functionally tested and verified by the human factor engineering. For the actual application to the operating plants, the drawings to be interconnected to the alarms and the opinions from the operators/maintenance departments for designating alarm number should be surveyed, Also, another function that allows the access to the alarm related drawings not only from the MCR but also from the other offices.

    We present new results of fully general relativistic magnetohydrodynamic simulations of binary neutron star (BNS) mergers performed with the Whisky code. All the models use a piecewise polytropic approximation of the APR4 equation of state for cold matter, together with a ‘hybrid’ part to incorporate thermal effects during the evolution. We consider both equal and unequal-mass models, with total masses such that either a supramassive NS or a black hole is formed after merger. Each model is evolved with and without a magnetic field initially confined to the stellar interior. We present the different gravitational wave (GW) signals as well as a detailed description of the matter dynamics (magnetic field evolution, ejected mass, post-merger remnant/disk properties). Our simulations provide new insights into BNS mergers, the associated GW emission and the possible connection with the engine of short gamma-ray bursts (both in the ‘standard’ and in the ‘time-reversal’ scenarios) and other electromagnetic counterparts.

    At first, standard design of APR1400 is designed to support the operation of the EOP using soft control of safety and non-safety like the control room of N4 and AP600. However, KINS required that the design of the soft control for the operation of the EOP is safety grade. According to the comment of the KINS, the concept of the soft control is changed into the concept of the separation of the safety and non-safety for the design of the soft control. KINS required that the result of the HFE suitability verification for changed design is submitted to obtain the approval of the design certification. It was assessed that channelized soft controller is advantageous at the side of operator's mistake prevention and convenience. But non-channelized soft control was assessed that it was the most advantageous considering human factor. Safety console operation strategy is assessed that it is properly without problem during experiment period.

    Abdominoperineal resection (APR) of anorectal cancers after neoadjuvant chemoradiotherapy may incur significant perineal morbidity. While vertical rectus abdominis muscle (V-RAM) flaps can fill the pelvic resection space with health tissue, their use has previously been described predominantly in association with laparotomy. Here, we describe a means of combination laparoscopic APR with V-RAM flap reconstruction that allows structural preservation of the entire abdominal wall throughout the oncological resection and of the deep parietal layers after V-RAM donation. Furthermore, a single port access device used at the end colostomy site allows a second senior surgeon assist with an additional two working instruments for the purpose of improved pelvic tissue retraction, especially useful in obese patients.

    According to the EUR (European Utility Requirements for LWR Nuclear Power Plants), it is mandatory that the HMS (Hydrogen Mitigation System) of the Eu-APR1400 should be equipped with a passive or automatic hydrogen control system. Considering this requirement, a PAR (Passive Autocatalytic Recombiner) system was adopted for the HMS of the Eu-APR1400. This passive HMS should be evaluated carefully in order to ensure that the HMS has adequate capacity to control hydrogen concentrations during severe accident conditions and to show that the system can satisfy the design requirements of the EUR. In this paper, analyses were carried out to examine the effectiveness of the HMS incorporated into the Eu- APR1400 design. These analyses were performed using the MAAP (Modular Accident Analysis Program) 4 code. in order to identify whether the HMS could control the average hydrogen concentrations in the containment, such that the concentration would not exceed 10 percent by volume: the analyses also considered whether there was the possibility of inadvertent hydrogen combustion in such processes as FA (Flame Acceleration) and DDT (Deflagration to Detonation Transition)

    The objective of this study is to develop a systematic approach to further reduce CBC at BOC and ultimately making MTC more negative, while maintaining cycle length and keeping pin peaking factor below the 1.55 safety limit. The methodology uses fuel assembly (FA) designs that contain both low and high Gd w/o rods. The APR 1400 fuel assembly and core design for Shin-Kori Unit 3 Cycle 1 (SK3C1), which is of PWR type, is used as reference case. The Gd-bearing assembly types in SK3C1, namely B1, B2, B3, C1, C2, and C3, uses Gd rods with 8 w/o gadolinia (Gd{sub 2}O{sub 3}) admixed in UO{sub 2}, and 2 w/o U-235 enrichment. FA and core depletions are simulated using CASMO 3.0 and MASTER 3.0 design codes, respectively. The methodologies described in Section 2 are applied to assemblies B1, C1 and C3. Interpolation of these assemblies' quadratic model equations is performed using the 0.11 factor to obtain Δk{sub FA} tables for B2, B3 and C2 assemblies. Once the design of all Gd-bearing assemblies are determined, core depletion is simulated. The summary of core depletion results is shown in Table II. It is clear that CBC at BOC is successfully reduced in the optimized core case, as also evident in Fig. 3. The amount of CBC reduction is less than the predicted 300 ppm. This is attributed to neutron leakage in core depletion simulation. The actual Δk{sub FA} computed using results of the optimized core simulation is 0.078, which is well within the 1% error of the quadratic model solutions and close to the analytically calculated value. Thus, the assumption made in Eq. is validated.

    In this research, a series of visualization works was conducted to understand droplet entrainment of the flow pattern generated in direct vessel injection system(DVI) of Korea nuclear power plant, APR 1400. In the emergency situation of a nuclear power plant, reliability of DVI cooling can be an important issue. It is known that, the amount and the rate of entrainment during the DVI cooling process can significantly affect the total heat removal. To visualize the film Reynolds number closely related with onset of droplet entrainment induced by falling film flow and lateral air flow in a small gap, confocal chromatic sensing method for measuring accurately film thickness and depth averaging particle image velocimetry for film velocity were used. The results have been post processed 4G Insight software. By measuring two dimensional film Reynolds number, we can predict the onset of droplet entrainment and obtain visible breakup region intuitively. To visualize the droplet entrainment induced by falling film flow and lateral air flow in a small gap, shadowgraph method with CCD camera (2200fps, 1280 pixel X 800 pixel, ) on coated plate with super water-repellent agent was used. The results have been post processed using 4G Insight software. By measuring two dimensional film Reynolds number, we can predict the onset of droplet entrainment and obtain visible breakup region intuitively. By adopting both super hydrophobic coating method and shadowgraph method, entrainment in a narrow gap was successfully visualized that has rarely performed before and meaningful results for DVI system research fields have been made.

    The Small Break Loss-of-Coolant Accident (SBLOCA) evaluation methodology (EM) for APR1400, called sEM, is now being developed using SPACE code. SPACE/sEM is to set up a conservative evaluation methodology in accordance with appendix K of 10 CFR 50. Major required and acceptable features of the evaluation models are described as below. - Fission product decay : 1.2 times of ANS97 decay curve - Critical flow model : Henry-Fauske Moody two phase critical flow model - Metal-Water reaction model : Baker-Just equation - Critical Heat Flux (CHF) : B and W, Barnett and Modified Barnett correlation - Post-CHF : Groeneveld 5.7 film boiling correlation A series of test matrix is established to validate SPACE/sEM code in terms of major SBLOCA phenomena, e.g. core level swelling and boiling, core heat transfer, critical flow, loop seal clearance and their integrated effects. The separated effect tests (SETs) and integrated effect tests (IETs) are successfully performed and these results shows that SPACE/sEM code has a conservatism comparing with experimental data. Finally, plant calculations of SBLOCA for APR1400 are conducted as described below. - Break location sensitivity : DVI line, hot-leg, cold-leg, pump suction leg. - Break size spectrum : 0.4ft{sup 2}∼0.02ft{sup 2}(DVI) 0.5ft{sup 2}∼0.02ft{sup 2}(hot-leg, cold-leg, pump suction leg) This paper deals with break size spectrum analysis of cold-leg break accidents. Based on the calculation results, emergency core cooling system (ECCS) performances of APR1400 and typical SBLOCA phenomena can be evaluated. Cold-leg SBLOCA analysis for APR1400 is performed using SPACE/sEM code under harsh environment condition. SPACE/sEM code shows the typical SBLOCA behaviors and it is reasonably predicted. Although SPACE/sEM code has conservative models and correlations based on appendix K of 10 CFR 50, PCT does not exceed the requirement (1477 K). It is concluded that ECCS in APR1400 has a sufficient performance in cold-leg SBLOCA.

    An amphibious inspection robot system (hereafter AIROS) is being developed to visually inspect the in-containment refueling storage water tank (hereafter IRWST) strainer in APR1400 instead of a human diver. Four IRWST strainers are located in the IRWST, which is filled with boric acid water. Each strainer has 108 sub-assembly strainer fin modules that should be inspected with the VT-3 method according to Reg. guide 1.82 and the operation manual. AIROS has 6 thrusters for submarine voyage and 4 legs for walking on the top of the strainer. An inverse kinematic algorithm was implemented in the robot controller for exact walking on the top of the IRWST strainer. The IRWST strainer has several top cross braces that are extruded on the top of the strainer, which can be obstacles of walking on the strainer, to maintain the frame of the strainer. Therefore, a robot leg should arrive at the position beside the top cross brace. For this reason, we used an image processing technique to find the top cross brace in the sole camera image. The sole camera image is processed to find the existence of the top cross brace using the cross edge detection algorithm in real time. A 5-DOF robot arm that has multiple camera modules for simultaneous inspection of both sides can penetrate narrow gaps. For intuitive presentation of inspection results and for management of inspection data, inspection images are stored in the control PC with camera angles and positions to synthesize and merge the images. The synthesized images are then mapped in a 3D CAD model of the IRWST strainer with the location information. An IRWST strainer mock-up was fabricated to teach the robot arm scanning and gaiting.

    Full Text Available An amphibious inspection robot system (hereafter AIROS is being developed to visually inspect the in-containment refueling storage water tank (hereafter IRWST strainer in APR1400 instead of a human diver. Four IRWST strainers are located in the IRWST, which is filled with boric acid water. Each strainer has 108 sub-assembly strainer fin modules that should be inspected with the VT-3 method according to Reg. guide 1.82 and the operation manual. AIROS has 6 thrusters for submarine voyage and 4 legs for walking on the top of the strainer. An inverse kinematic algorithm was implemented in the robot controller for exact walking on the top of the IRWST strainer. The IRWST strainer has several top cross braces that are extruded on the top of the strainer, which can be obstacles of walking on the strainer, to maintain the frame of the strainer. Therefore, a robot leg should arrive at the position beside the top cross brace. For this reason, we used an image processing technique to find the top cross brace in the sole camera image. The sole camera image is processed to find the existence of the top cross brace using the cross edge detection algorithm in real time. A 5-DOF robot arm that has multiple camera modules for simultaneous inspection of both sides can penetrate narrow gaps. For intuitive presentation of inspection results and for management of inspection data, inspection images are stored in the control PC with camera angles and positions to synthesize and merge the images. The synthesized images are then mapped in a 3D CAD model of the IRWST strainer with the location information. An IRWST strainer mock-up was fabricated to teach the robot arm scanning and gaiting. It is important to arrive at the designated position for inserting the robot arm into all of the gaps. Exact position control without anchor under the water is not easy. Therefore, we designed the multi leg robot for the role of anchoring and positioning. Quadruped robot design of

    This study was conducted to explore the capabilities of the S-CO{sub 2} Brayton cycle for a cogeneration system for APR-1400 application. Three concepts of the S-CO{sub 2} simple recuperated co-generation cycle were designed. A supercritical CO{sub 2} (S-CO{sub 2}) Brayton cycle is recently receiving significant attention as a promising power conversion system in wide range of energy applications due to its high efficiency and compact footprint. The main reason why the S-CO{sub 2} Brayton cycle has these advantages is that the compressor operates near the critical point of CO{sub 2} (30.98 .deg. C, 7.38MPa) to reduce the compression work significantly compared to the other Brayton cycles. In this study, the concept of replacing the entire steam cycle of APR-1400 with the S-CO{sub 2} Brayton cycle is evaluated. The power generation purpose S-CO{sub 2} Brayton cycles are redesigned to generate power and provide heat to the desalination system at the same time. The performance of these newly suggested cycles are evaluated in this paper. The target was to deliver 147MW heat to the desalination process. The thermal efficiencies of the three concepts are not significantly different, but the 3{sup rd} concept is relatively simpler than other cycles because only an additional heat exchanger is required. Although the 2{sup nd} concept is relatively complicated in comparison to other concepts, the temperatures at the inlet and outlet of the DHX are higher than that of the others. As shown in the results, the S-CO{sub 2} Brayton cycles are not easy to outperform the steam cycle with very simple layout and general design points under APR-1400 operating condition. However, this study shows that the S-CO{sub 2} Brayton cycles can be designed as a co-generation cycle while producing the target desalination heat with a simple configuration. In addition, it was also found that the S-CO{sub 2} Brayton cycle can achieve higher cycle thermal efficiency than the steam power cycle under

  6. The AprV5 subtilase is required for the optimal processing of all three extracellular serine proteases from Dichelobacter nodosus.

    Directory of Open Access Journals (Sweden)

    Xiaoyan Han

    Full Text Available Dichelobacter nodosus is the principal causative agent of ovine footrot and its extracellular proteases are major virulence factors. Virulent isolates of D. nodosus secrete three subtilisin-like serine proteases: AprV2, AprV5 and BprV. These enzymes are each synthesized as precursor molecules that include a signal (pre- peptide, a pro-peptide and a C-terminal extension, which are processed to produce the mature active forms. The function of the C-terminal regions of these proteases and the mechanism of protease processing and secretion are unknown. AprV5 contributes to most of the protease activity secreted by D. nodosus. To understand the role of the C-terminal extension of AprV5, we constructed a series of C-terminal-deletion mutants in D. nodosus by allelic exchange. The proteases present in the resultant mutants and their complemented derivatives were examined by protease zymogram analysis, western blotting and mass spectrometry. The results showed that the C-terminal region of AprV5 is required for the normal expression of protease activity, deletion of this region led to a delay in the processing of these enzymes. D. nodosus is an unusual bacterium in that it produces three closely related extracellular serine proteases. We have now shown that one of these enzymes, AprV5, is responsible for its own maturation, and for the optimal cleavage of AprV2 and BprV, to their mature active forms. These studies have increased our understanding of how this important pathogen processes these virulence-associated extracellular proteases and secretes them into its external environment.

    Over 400 million people living in the world's poorest developing nations are infected with hookworms, mostly of the genus Necator americanus. A bivalent human hookworm vaccine composed of the Necator americanus Glutathione S-Transferase-1 (Na-GST-1) and the Necator americanus Aspartic Protease-1 (Na-APR-1 (M74)) is currently under development by the Sabin Vaccine Institute Product Development Partnership (Sabin PDP). Both monovalent vaccines are currently in Phase 1 trials. Both Na-GST-1 and Na-APR-1 antigens are expressed as recombinant proteins. While Na-GST-1 was found to express with high yields in Pichia pastoris, the level of expression of Na-APR-1 in this host was too low to be suitable for a manufacturing process. When the tobacco plant Nicotiana benthamiana was evaluated as an expression system, acceptable levels of solubility, yield, and stability were attained. Observed expression levels of Na-APR-1 (M74) using this system are ∼300 mg/kg. Here we describe the achievements and obstacles encountered during process development as well as characterization and stability of the purified Na-APR-1 (M74) protein and formulated vaccine. The expression, purification and analysis of purified Na-APR-1 (M74) protein obtained from representative 5 kg reproducibility runs performed to qualify the Na-APR-1 (M74) production process is also presented. This process has been successfully transferred to a pilot plant and a 50 kg scale manufacturing campaign under current Good Manufacturing Practice (cGMP) has been performed. The 50 kg run has provided a sufficient amount of protein to support the ongoing hookworm vaccine development program of the Sabin PDP.

    Full Text Available Construites à partir des années 1960 sous l’impulsion du Schéma directeur d’Aménagement et d’Urbanisme de 1965, cinq villes nouvelles ont vu le jour en région parisienne. Leur aménagement laisse entrevoir une volonté de répondre à des besoins urbains identifiés, se conjuguant parfois avec l’offre d’espaces, de services ou d’équipements envisagés alors comme novateurs. Maurepas, rattachée jusqu’en 1984 à l’agglomération nouvelle de Saint-Quentin-en-Yvelines, a été façonnée en partie par ces aspirations. Elle constitue aujourd’hui une commune à la population vieillissante et à l’urbanisme marqué par des jeux d’échelle, des cloisonnements et par une relative uniformité. La configuration de la ville laisse entrevoir la volonté d’ébaucher « un nouveau genre de vie urbaine »(Pachaud, 2006 manifeste durant les années soixante et soixante-dix tandis que l’histoire de la commune permet d’envisager les difficultés inhérentes à l’intercommunalité. Au cœur de cette histoire se retrouvent des ménages de la classe moyenne, entrés dans le périurbain comme des pionniers. Portés par l’idéologie d’une ville-nouvelle où « tout est à construire » et qui leur ouvrait, parallèlement, des perspectives nouvelles en termes « d’espaces à soi », ces derniers sont aujourd’hui âgés de plus de soixante ans. Quarante ans après leur installation, leurs discours sur la ville révèlent l’existence de plusieurs ordres de tension : tension entre ruralité et urbanité, d’une part, tension entre adhésion, différenciation et réflexivité, de l’autre. Ces tensions peuvent être mises en parallèle avec les évolutions de la ville et la façon dont les formes urbaines sont mises en question dans l’espace des débats publics. Ces différents éléments nous conduiront à envisager les résistances et les projections à l’œuvre ainsi que les processus de subjectivation qu’elles r

    Bacterial proteases are involved in food spoilage and shelf-life reduction. Among the bacterial proteases, a predominant role in spoilage of dairy products seems to be played by the thermostable metallo-protease AprX, which is produced by various strains of Pseudomonas fluorescens. Differences in AprX enzyme activity among different strains were highlighted, but the most proteolytic strains were not identified. In this study, the presence of the aprX gene was evaluated in 69 strains isolated from food matrices and 18 reference strains belonging to the P. fluorescens group, which had been previously typed by the multi locus sequence typing method. Subsequently, a subset of reference strains was inoculated in ultra-high temperature milk, and the expression of the aprX gene was evaluated at 22 and 6°C. On the same milk samples, the proteolytic activity was then evaluated through Azocasein and trinitrobenzenesulfonic acid solution assays. Finally, to assess the applicability of the former assay directly on dairy products the proteolityc activity was tested on industrial ricotta samples using the Azocasein assay. These results demonstrate the spread of aprX gene in most strains tested and the applicability of Azocasein assay to monitor the proteolytic activity in dairy products.

    As part of the project for acquiring the certification from EUR organization, in accordance with Articles 4.8 and 5.5 specified in Section 2.20 of EUR Volume 2, the effects of ionizing radiation from the standard design of EU-APR on biota and ecosystems during operation and decommissioning phases shall be assessed. This assessment must be carried out according to the ERICA (i.e. Environmental Risk from Ionizing Contaminants: Assessment and management) integrated approach. This paper describes the evaluation results for unit risk quotient and relative significance by radionuclide derived from performing Tier 1 assessment on flora and fauna for the EU-APR design using ERICA Tool. As specified previously, Pa-231 and Th-228 are the most significant for the terrestrial and for the marine/freshwater ecosystems, respectively. And, in terms of environmental risk, those radionuclides having the most impact on flora and fauna are relatively more significant than isotope having the least impact by about 7 to 10 orders of magnitude.

    In Korea, Advanced Power Reactor Plus (APR+) has being developed by adding passive safety features to Advanced Power Reactor 1400MWe (APR1400). Passive Auxiliary Feedwater System (PAFS) is one of passive system adopted in the APR+ to replace the conventional active auxiliary feedwater system. Because PAFS removes decay heat from the reactor core, it is required to verify the performance of PAFS in postulated accidents cases. In addition, an effect of noncondensable gas on the heat removal capability of PAFS should be evaluated since the non-condensable gas may deteriorate a condensation heat transfer through the condensation heat exchanger in PAFS. In this study, the effect of N{sub 2} gas was evaluated using MARS

  13. The subtilisin-like protease AprV2 is required for virulence and uses a novel disulphide-tethered exosite to bind substrates.

    Directory of Open Access Journals (Sweden)

    Full Text Available Many bacterial pathogens produce extracellular proteases that degrade the extracellular matrix of the host and therefore are involved in disease pathogenesis. Dichelobacter nodosus is the causative agent of ovine footrot, a highly contagious disease that is characterized by the separation of the hoof from the underlying tissue. D. nodosus secretes three subtilisin-like proteases whose analysis forms the basis of diagnostic tests that differentiate between virulent and benign strains and have been postulated to play a role in virulence. We have constructed protease mutants of D. nodosus; their analysis in a sheep virulence model revealed that one of these enzymes, AprV2, was required for virulence. These studies challenge the previous hypothesis that the elastase activity of AprV2 is important for disease progression, since aprV2 mutants were virulent when complemented with aprB2, which encodes a variant that has impaired elastase activity. We have determined the crystal structures of both AprV2 and AprB2 and characterized the biological activity of these enzymes. These data reveal that an unusual extended disulphide-tethered loop functions as an exosite, mediating effective enzyme-substrate interactions. The disulphide bond and Tyr92, which was located at the exposed end of the loop, were functionally important. Bioinformatic analyses suggested that other pathogenic bacteria may have proteases that utilize a similar mechanism. In conclusion, we have used an integrated multidisciplinary combination of bacterial genetics, whole animal virulence trials in the original host, biochemical studies, and comprehensive analysis of crystal structures to provide the first definitive evidence that the extracellular secreted proteases produced by D. nodosus are required for virulence and to elucidate the molecular mechanism by which these proteases bind to their natural substrates. We postulate that this exosite mechanism may be used by proteases produced by

    • Perception of nuclear power as a convenient, economically competitive and viable source of energy which, if introduced in the country, would not only complement the traditional energy sources, but would also promote technological development and serve as an incentive for social and economic progress. In this paper we will introduce APR-1400 as the most likely selected reactor type for 1st Egyptian Nuclear Power Plant. Then we will study the optimized APR-1400 condenser performance based on El-Dabaa site conditions. As the climate conditions, especially the seawater temperatures (intake for the cooling system) having a direct effects on the condenser performance and the overall NPP Efficiency, we studied the seawater temperature change based on EL-Dabaa site conditions and it's feedback on the proposed APR-1400 condenser performance and the NPP efficiency. All of the calculations and analysis had been executed by using KINGS NPA by applying EL-Dabaa seawater temperature variations for the 2 types of APR-1400 Condensers (Shinkori, south Korea and Barakah, UAE), and the main findings were as follow: For the APR-1400 condensers (Shinkori and Barakah) performance • The average difference all over the year for saturation temperature, cooling water outlet temperature, and condenser pressure are 0.135 .deg. C, .05785 .deg. C, and 0.3948 mHgA respectively. This shows that the Barakah condenser performance is not significantly better than the shinkori condenser performance based on EL-Dabaa Conditions, especially if we considered the cost difference between the two condensers designs. For APR-1400 NPPs (Shinkori and Barakah) net efficiency • The average difference all over the year for the power productions and net efficiency are 1.4791 MWe and .00037 %, respectively.

    In order to enhance the safety feature of the APR1400 through the passive ways, the passive auxiliary feedwater system(PAFS) is under preliminary consideration by KAERI. For the successful adaptation of PAFS, accident scenario evaluation of PWR plant that is assumed to have the PAFS system should be performed. Condensing heat exchanger assemblies are installed at the exterior boundary of the containment building per one steam generator. The performance of the heat exchanger is designed to remove the decay heat of the fuel completely. In normal operation condition, PAFS system is not connected with the steam and feed lines. A Total Loss of Feed Water(TLOFW) accident is selected for the performance and scenario evaluation after the severity check. The PAFS connection valves are open at the signal of 25% level trip of steam generator. With the single failure assumption of PAFS open valve, the scenario propagations are calculated by using MARS code.

    Les carcinoïdes primitifs du rein sont rares avec une centaine de cas rapportés dans la littérature. Sur le plan histologique, il s'agit d'une tumeur bien différenciée dont la morphologie rejoint souvent celle des carcinoïdes dans les autres localisations. Nous rapportons un cas de carcinoïde primitif du rein survenant chez un homme de 41 ans, découvert à la suite de métastases hépatiques. La tumeur était particulière par son architecture tubulo-papillaire, suggérant à tort le diagnostic de carcinome papillaire du rein. Ce diagnostic a été redressé 12 ans après, à la suite de l'apparition d'autres métastases hépatiques, osseuses et pulmonaires. PMID:27217899

    PRIMA-1met (APR-246) is a methylated derivative and structural analog of PRIMA-1 (p53 re-activation and induction of massive apoptosis). PRIMA-1met has been reported to restore both the wild type (wt) structure and function of mutant p53. Here, we show that PRIMA-1met is highly effective at limiting the growth of CRC cells regardless of p53 status. However, PRIMA-1met induces robust apoptosis only in CRC cells with mutant p53. Upregulation of Noxa, a proapoptotic molecule, is crucial for PRIMA-1met mediated activity. In human xenograft model of disease, PRIMA-1met effectively suppresses CRC tumor growth. Our results uncover distinct mechanisms of PRIMA-1met in CRC with different p53 status, thus providing a mechanistic rationale to evaluate the clinical efficacy of PRIMA-1met in CRC patients with different p53 status.

Providing an additional Emergency Diesel Generator (EDG); 2. Increasing the capacity of Class 1E batteries; 3. Placing a Refueling Water Storage Tank (RWST) inside containment, i.e., change from RWST to IRWST. The Advanced Power Reactor 1400 (APR-1400) adopts several advanced safety features compared to its predecessor, the Optimized Power Reactor 1000 (OPR-1000), which includes an additional Emergency Diesel Generator, increase in battery capacity, in-containment refueling water storage tank (IRWST), and so on. Considering the remarkable advantages of these safety features in safety improvement and the design similarities between APR-1400 and OPR-1000, it is feasible to apply key advanced safety features of APR-1400 to OPR-1000 to enhance the safety. The selected safety features are incorporated into OPR-1000 PSA model using the Advanced Information Management System (AIMS) for PSA and CDFs are re-evaluated for each application and combination of three applications. Based on current results, it is concluded that three of key advanced safety features of APR-1400 can be effectively applied to OPR-1000, resulting in considerable safety improvement. In aggregate, three advanced safety features, which are an additional EDG, increased battery capacity and IRWST, can reduce the CDF of OPR-1000 by more than 15% when applied altogether.

    Highlights: • Hydrogen behavior in the containment building of APR1400 nuclear plant up to 15 h after the failure happened. • The risk of hydrogen explosion largely depends on the combination of air, hydrogen and steam in the containment. • Hydrogen explosion risk at different locations in the containment was analyzed. - Abstract: This paper describes the analytical result of the potential risk of hydrogen gas up to 15 h after the failure takes place. The major cause of the disaster occurred in Fukushima Daiichi nuclear reactor was the detonation of accumulated hydrogen in the containment by highly increased reactor core temperatures after the failure of the emergency cooling system. The hydrogen risk should be considered in severe accident strategies in current and future NPPs. A hydrogen explosion scenario is proposed. Hydrogen is accumulated on top of the dome during the hydrogen release period. At this point, there are no risk of explosion due to the steam that resides in upper part of the dome. As the hydrogen concentration increase, substantial amount of steams are released. Subsequently, hydrogen is forced into the lower part of the building with high air density—small explosion and dormant steam condensation phase are possible. The light hydrogen rises up slowly with air, gathering on top of the building with high air density. Massive hydrogen explosion is anticipated upon ignition at this stage.

    Gamma irradiation leads to an increased production of interleukin- (IL)-6 and IL-8 by human endothelial cells. In order to regulate the radio-induced production of these pro-inflammatory cytokines, we used the immunoregulatory cytokines IL-4 and IL-10. These agents were added either before or after a 10 Gy-irradiation. Our results show that it is possible to decrease the radio-induced production of IL-6 and IL-8 with the use of IL-4 and IL-10. Differences in the intensity of the response have been observed according to the time of treatment. The anti-inflammatory potential of both IL-4 and IL-10 was more pronounced when added after irradiation. Après irradiation gamma, des cellules endothéliales humaines ont une production accrue des interleukines (IL-) -6 et -8. Dans le but de réguler la production de ces cytokines pro-inflammatoires, nous avons utilisé des cytokines dites anti-inflammatoires, l'IL-4 et l'IL-10. Ces agents ont été ajoutés soit avant soit après une irradiation de 10Gy. Nos résultats montrent qu'il est possible de diminuer les productions radio-induites d'IL-6 et d'IL-8 par l'IL-4 et l'IL-10. Des différences dans l'intensité de la réponse ont toutefois été observées selon que l'IL-4 ou l'IL-10 ont été ajoutées avant ou après irradiation; leur efficacité anti-inflammatoire étant plus marquée lorsque les cytokines sont ajoutées après l'irradiation.

    The method was developed to have a conservatism to cover the uncertainty of analysis and the acceptance is judged by the representative bounding estimation. However, the important safety parameters such as the available driving head need to be confirmed by the plant specific calculation. Also an interaction between the debris induced head loss and the core flow rate needs to be explained because the head loss induced by debris in actual condition may reduce the core inflow rate faster. To confirm the safety parameters, in this study, thermal-hydraulic response considering the core inlet blockage (CIB) by debris during LTCC process following a double-ended guillotine break of cold leg (CLB), one of hot leg (HLB) and one of intermediate leg (ILB) of the APR1400 were calculated, respectively. MARS-KS 1.3 code has been used. The CIB has been modeled by the closure of valves to the core in exponential manner with time to observe the behavior near the complete blockage. To understand the effect of core inlet blockage (CIB) during a long term core cooling (LTCC) phase following a loss-of-coolant accident (LOCA) in the light of in-vessel downstream effect (IDE) of Generic Safety Issue (GSI) 191, double-ended guillotine break of hot leg (HLB), one of cold leg (CLB) and one of intermediate leg (ILB) were calculated, respectively. And the important safety parameters such as the available driving head and the head loss due to debris were calculated using MARS-KS code and discussed in comparison with the WCAP method. As a result, a little delayed heatup behavior of the fuel cladding was found for all the cases, which due to the redistribution of flow within the core after blockage.

    Our previous study demonstrated that Melaleuca alternifolia (tea tree) oil (TTO) had an interesting antiviral activity against Influenza A in MDCK cells. In fact, when we tested TTO and some of its components, we found that TTO had an inhibitory effect on influenza virus replication at doses below the cytotoxic dose; terpinen-4-ol, terpinolene, and alfa-terpineol were the main active components. The aim of this study was to investigate the mechanism of action of TTO and its active components against Influenza A/PR/8 virus subtype H1N1 in MDCK cells. None of the test compounds showed virucidal activity nor any protective action for the MDCK cells. Thus, the effect of TTO and its active components on different steps of the replicative cycle of influenza virus was studied by adding the test compounds at various times after infection. These experiments revealed that viral replication was significantly inhibited if TTO was added within 2h of infection, indicating an interference with an early step of the viral replicative cycle of influenza virus. The influence of the compound on the virus adsorption step, studied by the infective center assay, indicated that TTO did not interfere with cellular attachment of the virus. TTO did not inhibit influenza virus neuraminidase activity, as shown by the experiment measuring the amount of 4-methylumbelliferone, cleaved by the influenza virus neuraminidase from the fluorogenic substrate 2'-O-(4-methylumbelliferyl)-N-acetylneuraminic acid. The effect of TTO on acidification of cellular lysosomes was studied by vital staining with acridine orange using bafilomycin A1 as positive control. The treatment of cells with 0.01% (v/v) of TTO at 37°C for 4h before staining inhibited the acridine orange accumulation in acid cytoplasmic vesicles, indicating that TTO could inhibit viral uncoating by an interference with acidification of intralysosomal compartment.

    Résumé Objectif Traiter des différentes éventualités pouvant survenir durant le suivi clinique et la prise en charge prolongés des patients prenant de nouveaux anticoagulants oraux (NACO). Qualité des données Aux fins de cette révision narrative (non systématique), nous avons effectué une recherche dans la base de données PubMed afin de relever des études cliniques récentes (soit de janvier 2008 à la semaine 32 de 2013) portant sur l’emploi des NACO pour la prévention des AVC dans les cas de fibrillation auriculaire et le traitement de la thromboembolie veineuse aiguë. Nous avons utilisé cette base de données probantes pour répondre à nos questions prédéfinies ayant trait à l’emploi des NACO en pratique générale. Message principal Le dabigatran et le rivaroxaban doivent être pris avec les repas afin de limiter la dyspepsie et de favoriser l’absorption, respectivement. Aucun NACO n’est accompagné de restrictions alimentaires, à l’exception de la consommation modérée d’alcool, et le rivaroxaban et l’apixaban peuvent être écrasés, au besoin. Les antiacides ne semblent pas perturber l’efficacité des NACO. Comme c’est le cas avec la warfarine, les patients traités aux NACO doivent éviter l’emploi prolongé d’anti-inflammatoires non stéroïdiens et d’antiplaquettaires. Chez les patients devant subir une chirurgie, il faut interrompre la prise de NACO de 2 à 5 jours avant l’intervention, en fonction du risque de saignement, et le traitement par le NACO doit être habituellement repris au moins 24 heures après la chirurgie. Il n’est habituellement pas nécessaire d’effectuer un test préopératoire de coagulation. Chez les patients qui développent un saignement, un saignement mineur ne justifie habituellement pas un test de laboratoire ni l’interruption du traitement par le NACO; dans le cas des saignements majeurs, il faut se concentrer sur l’application de mesures localisées visant à endiguer le

    Small cell lung cancer (SCLC) is a highly malignant disease with poor prognosis, necessitating the need to develop new and efficient treatment modalities. PRIMA-1(Met) (p53-dependent reactivation of massive apoptosis), also known as APR-246, is a small molecule, which restores tumor suppressor...... function to mutant p53 and induces cancer cell death in various cancer types. Since p53 is mutated in more than 90% of SCLC, we investigated the ability of PRIMA-1(Met) to induce apoptosis and inhibit tumor growth in SCLC with different p53 mutations....

    2011-02-01

    For almost 45 years, the experience of Jewish children who were hidden during World War II was considered to be of little importance, particularly with respect to what had taken place in the concentration camps. Their very history was ignored in the many accounts of the Holocaust. It was only at the end of the 1980s that their experience began to be thought of as potentially traumatic. In this paper, the authors report on their psychoanalytical research project concerning the psychological outcomes of those experiences that had remained concealed for such an extraordinarily long latency period. The results are based on the analysis of 60 accounts and on psychoanalytically-oriented group work. The authors show that the trauma experienced by those hidden children was triggered by the retroactive effect of a deferred action [après-coup]. Copyright © 2010 Institute of Psychoanalysis.

    The absolute binding free energies and binding enthalpies of twelve host-guest systems in the SAMPL5 blind challenge were computed using our attach-pull-release (APR) approach. This method has previously shown good correlations between experimental and calculated binding data in retrospective studies of cucurbit[7]uril (CB7) and β-cyclodextrin (βCD) systems. In the present work, the computed binding free energies for host octa acid (OA or OAH) and tetra-endo-methyl octa-acid (TEMOA or OAMe) with guests are in good agreement with prospective experimental data, with a coefficient of determination (R2) of 0.8 and root-mean-squared error of 1.7 kcal/mol using the TIP3P water model. The binding enthalpy calculations achieve moderate correlations, with R2 of 0.5 and RMSE of 2.5 kcal/mol, for TIP3P water. Calculations using the newly developed OPC water model also show good performance. Furthermore, the present calculations semi-quantitatively capture the experimental trend of enthalpy-entropy compensation observed, and successfully predict guests with the strongest and weakest binding affinity. The most populated binding poses of all twelve systems, based on clustering analysis of 750 ns molecular dynamics (MD) trajectories, were extracted and analyzed. Computational methods using MD simulations and explicit solvent models in a rigorous statistical thermodynamic framework, like APR, can generate reasonable predictions of binding thermodynamics. Especially with continuing improvement in simulation force fields, such methods hold the promise of making substantial contributions to hit identification and lead optimization in the drug discovery process.

    Full Text Available Plastic reconstructive surgery from a pediatric surgical point of view means more than to apply adult surgical techniques and methods to pediatric conditions. A child’s multidimensional characteristics and particularity, development potential, wishes and expectations must be respected during planning and conduction of surgical procedures. In this article the relevance of the four pillars of plastic surgery for the different phases of childhood are portrayed. Especially the legal and ethnic problems of treatment modalities of disorders of sex differentiation are discussed, particularly taking into consideration the heterogeneity of this entity. We see no indication for gender assigning operations during childhood since an informed consent cannot be obtained due to the age of the patient. A cosmetic and only gender emphasizing operation for a child with congenital adrenal hyperplasia may only be performed in concordance with the guidelines of the German Ethics Council and after extensive and independent consultation.

    Highlights: • Ex-vessel core catcher of PECS is installed in EU-APR1400. • CE-PECS has been conducted to test a cooling capability of the PECS. • Two phase flow in CE-PECS and PECS was analyzed using RELAP5/MOD3. • RELAP5 results are very similar to the CE-PECS data. • The super-step design is suitable for steam injection into the downcomer in PECS. - Abstract: The ex-vessel core catcher of the PECS (Passive Ex-vessel corium retaining and Cooling System) is installed to retain and cool down the corium in the reactor cavity of the EU (European Union)-APR (Advanced Power Reactor) 1400. A verification experiment on the cooling capability of the PECS has been conducted in the CE (Cooling Experiment)-PECS. Simulations of a two-phase natural circulation flow using the RELAP5/MOD3 computer code in the CE-PECS and PECS have been conducted to predict the two-phase flow characteristics, to determine the natural circulation mass flow rate in the cooling channel, and to evaluate the scaling in the experimental design of the CE-PECS. Particularly from a comparative study of the prototype PECS and the scaled test facility of the CE-PECS, the orifice loss coefficient in the CE-PECS was found to be 6 to maintain the coolant circulation mass flux, which is approximately 273.1 kg/m{sup 2} s. The RELAP5 results on the coolant circulation mass flow rate are very similar to the CE-PECS experimental results. An increase in the coolant injection temperature and the heat flux lead to an increase in the coolant circulation mass flow rate. In the base case simulation, a lot of vapor was injected into the downcomer, which leads to an instability of the two-phase natural circulation flow. A super-step design at a downcomer inlet is suitable to prevent vapor injection into the downcomer piping.

    Folic acid supplementation and food fortification policies have improved folate status in North American women of child bearing age. Recent studies have reported the possible inadequacy of vitamin B12 and B6 in the etiology of neural tube defects in folate-fortified populations. The aims of this study were to describe folate status and its relationship to supplementation and to assess vitamin B12 and B6 status in a cohort of pregnant women. Supplement intake data were collected in each trimester from the first cohort (n = 599) of the Alberta Pregnancy Outcomes and Nutrition (APrON) study. Red blood cell folate (RBCF) and plasma folate, holotranscobalamin, and pyridoxal 5-phosphate were measured. Overt folate deficiency was rare (3%) but 24% of women in their first trimester had suboptimal RBCF concentration (1360 nmol·L(-1)) was observed in approximately half of the women during each pregnancy trimester. Vitamin B12 and B6 deficiencies were rare (pregnancy and over half the women had abnormally high RBCF, suggesting that supplementation during pregnancy is not appropriate in a cohort of women considered to be healthy and a low risk for nutritional deficiencies.

    The safety features function to localize, control, mitigate, and terminate such incidents and to hold exposure levels below applicable limits. The safety injection system is comprised of four independent mechanical trains without any tie line among the injection paths and two electrical divisions. Each train has one active Safety Injection Pump (SIP) and one passive Safety Injection Tank (SIT) equipped with a Fluidic Device (FD), each train provides 50% of the minimum injection flow rate for breaks larger than the size of a direct vessel injection line. For breaks equal to or smaller than the size of a direct vessel injection line, each train has 100% of the required capacity. The low pressure injection pumps with common header installed in the conventional design are eliminated, and the functions for safety injection and shutdown cooling are separated. The arrangement of safety injection system for APR-1400 as shown in figure (1). The results obtained in this work show that STI extensions for the SIS feasible without any unacceptable increase in the plant total risk, STI extensions are acceptable for safety injection system to provide plant operational flexibility in the performance of both corrective and preventive maintenance for the safety injection system.

    Full Text Available Cet article traite du rôle des musiciens dans la marine américaine pendant la Seconde Guerre mondiale. L’histoire de l’USS Arizona — et de son orchestre, noyé avec le cuirassé lors de l’attaque surprise des forces japonaises — étant bien connue, je m’appuie sur cet exemple comme point de départ afin de contextualiser la situation des musiciens militaires après les événements de Pearl Harbor, en décembre 1941. Dans le sillage de ce grand moment de l’Histoire, j’évoque ici des histoires à une autre échelle, celle de la « micro-histoire »— celle d’un militaire seul au milieu d’autres militaires. À travers les lettres échangées entre des recrues ayant suivi ensemble la même formation, je trace ici leurs expériences de guerre en tant qu’artistes, ainsi que les divers conflits pratiques et idéologiques qui se manifestent dans la tension entre l’art musical et l’art martial.

O resultado sugere que a versão linear desse arcabouço não seja capaz de apreçar ou de prever retornos reais de fundos que possuam elevados patrimônio líquido (PL e outperformance, em relação ao índice da Bolsa de Valores de São Paulo (Ibovespa, corroborando evidências anteriores. A versão não linear com thresholds baseados no PL parece lidar melhor com a questão de alfas de Jensen significativos, apesar de ser estatisticamente indicada apenas para poucos fundos com elevado PL, mas baixa outperformance. Essa é uma evidência de que, apesar de o tamanho influenciar na gestão e, possivelmente, na performance de um fundo, a modelagem de apreçamento desse efeito deve ser feita linearmente.

  14. A Study on Large Display Panel Design for the Countermeasures against Team Errors within the Main Control Room of APR-1400

    The personal aspect of human errors has been mainly overcome by virtue of the education and training. However, in the system aspect, the education and training system needs to be reconsidered for more effective reduction of human errors affected from various systems hazards. Traditionally the education and training systems are mainly not focused on team skills such as communication, situational awareness, and coordination, etc. but individual knowledge, skill, and attitude. However, the team factor is one of the crucial issues to reduce the human errors in most industries. In this study, we identify the emerging types of team errors, especially, in digitalized control room of nuclear power plants such as the APR-1400 main control room. Most works in nuclear industry are to be performed by a team of more than two persons. Even though the individual errors can be detected and recovered by the qualified others and/or the well trained team, it is rather seldom that the errors by team could be easily detected and properly recovered by the team itself. Note that the team is defined as two or more people who are appropriately interacting with each other, and the team is a dependent aggregate, which accomplishes a valuable goal. Team error is one of the typical organizational errors that may occur during performing operations in nuclear power plants. The large display panel is a representative feature of digitalized control room. As a group-view display, the large display panel provides plant overview to the operators. However, in terms of team performance and team errors, the large display panel is on a discussion board still because the large display panel was designed just a concept of passive display. In this study, we will propose revised large display panel which is integrated with several alternative interfaces against feasible team errors.

    Determination of absorbed dose in biological targets after high LET α particules irradiation needs heavy calculations. A softwave has been developed in order to allow everyone to calculate hit probability and absorbed dose. It is particularly adapted to the study of cell cultures irradiated with electrodeposited source or α-beam accelerator. It is based first, on a random generator of α-track homogeneously distributed in 4π, second, on the evaluation of energy loss in the different media along the track and then on a statistical analysis of the results. This method is accurate and low time consuming. The target is either modelised by an ellipsoid or represented by its 3D shape recorded using confocal microscopy. Des calculs dosimétriques complexes sont nécessaires pour l'évaluation des doses délivrées dans des cibles biologiques après irradiation par des particules α de haut TEL. Un logiciel a été développé pour rendre facilement accessible le calcul de la probabilité pour atteindre la cible et de la dose absorbée. il est particulièrement adapté à l'étude des cultures cellulaires irradiées par des sources électrodéposées de radionucléides ou des accélérateurs de particules. Il repose sur un générateur de traces aléatoires, sur une approximation de la perte d'énergie dans les différents milieux traversés et sur une exploitation statistique des résultats obtenus. Cette méthode s'avère précise et rapide. La cible est modélisée par un ellipsoïde ou représentée par son image 3D obtenue en microscopie confocale.

    Downcomer boiling phenomena is one of the key issues for a postulated large-break LOCA (LBLOCA) in a conventional pressurized water reactor, because it can degrade the hydraulic head of the coolant in the downcomer and consequently affect the reflood flow rate for a core cooling. To investigate the thermal hydraulic behavior in the downcomer region of the APR1400, a test program for a downcomer boiling is being progressed for the reflood phase of a postulated LBLOCA. Test was performed in a one side heated rectangular test channel which was designed by adopting a full-pressure, full-height, and full-size downcomer-gap approach, but with the circumferential length was reduced 47.08-fold. The test consists of two steps: (I) for the global two-phase flow parameters and (II) for the local two-phase flow parameters. The step-I test has already been completed. In the present paper, the experimental results of the step-II test are introduced. (authors)

    La transplantation rénale (TR) constitue le traitement de choix de l'insuffisance rénale chronique terminale. Les complications métaboliques après TR (diabète, dyslipidémie, hyperuricémie, obésité), en grande partie liées au traitement immunosuppresseur, deviennent une préoccupation car elles constituent un facteur de risque de morbimortalité et de perte fonctionnelle du greffon. Le but de notre étude est d’évaluer la fréquence de ces anomalies après TR. Il s'agit d'une étude rétrospective incluant tous les patients ayant bénéficié d'une première TR par donneur vivant (DV) de Juin 1998 à Décembre 2010. Nous avons recensé les données démographiques propres au receveur, le traitement immunosuppresseur après TR. Les paramètres clinico-biologiques recueillis sont (index de masse corporel (IMC), glycémie à jeun, hémoglobine glyquée, CT, C-HDL, C-LDL, TG, acide urique). Soixante dix patients ont été colligés, l’âge moyen est de 36.3 + /-9.6 ans (21 à 62) avec un sex ratio de 0.5. Quinze patients (21.4%) étaient hypertendus avant la TR et 2.9% avaient une néphropathie diabétiques. L’âge moyen du donneur est de 47.5 + /-10.2 ans (20-65). Le traitement immunosuppresseur pendant la phase d'induction était une trithérapie associant corticostéroïdes, anticalcineurines chez tous les patients et mycophénolate mofétil chez 68.6% et azathioprine dans 31.4% des cas. L'IMC moyen était de 24.1 + /-4.0 (16.9 à 37), 33% des patients étaient considérés en surpoids dont 21.8% en obésité. L'hypercholestérolémie, a été retrouvée chez 25 patients soit 36%. Presque la moitié des patients (48.5%) avaient une hyperuricémie. Quatre patients ont développé un diabète après TR soit 6% des cas. La perte du greffon a été notée chez 12 patients et 2 patients sont décédés dont un avec un greffon fonctionnel. En analyse univariée, l'hyperuricémie et la dyslipidémie ont été considérées comme facteur de risque de perte

    Full Text Available L’effondrement des tours jumelles de Manhattan le 11 septembre 2001 a renversé le rapport existant entre législatif et exécutif américains. Alors que certains avaient pu qualifier George W. Bush après son élection de « premier président post-impérial » face à un Congrès en pleine reconquête de ses prérogatives depuis la fin de la guerre froide, l’entrée des Etats-Unis dans la « guerre contre la terreur » a vu le retour d’une présidence impériale, et réduit les parlementaires à un rôle de quasi figuration. Historiquement, l’évolution semble attendue. Les phases d’extraversion de l’Amérique ont toujours correspondu à une affirmation de la prééminence présidentielle. Plus encore, en temps de crise et dès lors que la sécurité du peuple est en jeu, la prérogative constitutionnelle qui fait du président le commandant en chef des forces armées du pays lui donne une marge de manœuvre incomparable dans l’élaboration de la politique étrangère. Il était logique que le 11 septembre garantisse à Bush la victoire sur le Congrès dans la « compétition pour le privilège de conduire la politique étrangère du pays ». Les parlementaires se sont montrés particulièrement complaisants face à l’expansion des pouvoirs de l’exécutif, qu’ils ont souvent eux-mêmes autorisée – en particulier dans les mois qui ont suivi les attaques, puis par la suite, en raison de l’utilisation habile par Bush et le parti républicain d’une « politique de la peur » particulièrement efficace. Mais l’Administration Bush est allée beaucoup plus loin que cette simple logique. Par la pratique des signing statements, « déclarations de signature » ajoutées aux lois, le Président s’est accordé le droit d’interpréter, voire de choisir ou de corriger, certaines portions de la législation votée par le Congrès. Cette pratique n’a pas été inventée par Bush mais, qualitativement comme

    Obiettivi: valutare l’appropriatezza organizzativa dei ricoveri effettuati in un Policlinico Universitario attraverso la comparazione di due metodi, dei quali uno basato sui dati della scheda di dimissione ospedaliera ed utilizza, rispettivamente, i sistemi di classificazione iso-gravità APR-DRG e Disease Staging e l’altro sulla revisione delle cartelle cliniche mediante il PRUO.

    Metodi: oggetto di analisi sono i ricoveri ordinari effettuati nell’anno 2001 ed afferenti ai DRG inclusi nella delibera della Giunta Regionale del Lazio 864/2002 che recepisce il D.P.C.M. 29/11/2001 sui livelli essenziali di assistenza.

    Risultati: i risultati evidenziano che le due varianti del
    metodo basato sulla SDO (metodo APPRO mostrano quote di ricoveri inappropriati sovrapponibili rispetto al complesso dei ricoveri oggetto di analisi, ma con differenze anche rilevanti tra APR-DRG e Disease Staging in relazione ai singoli DRG considerati, riconducibili ai diversi algoritmi di attribuzione del livello di severità utilizzati dai due sistemi. L’analisi campionaria effettuata con il metodo PRUO su casi afferenti ai DRG della DGR 864/2002 caratterizzati da livelli di severità minimi evidenzia una proporzione di ricoveri inappropriati superiore a quella determinata tramite i metodi basati sulla SDO. Tale differenza è verosimilmente dovuta al ruolo del valore delle soglie percentuali di accettabilità individuate dalla Regione Lazio per ciascun DRG: le quote di ricoveri che eccedono tali soglie sono considerate inappropriate.

    Conclusioni: sulla base dei risultati ottenuti gli autori
    descrivono gli interventi organizzativi adottati per ottimizzare il contesto di erogazione delle prestazioni
    oggetto di analisi, discutono vantaggi e limiti dei metodi SDO-based e del metodo analitico PRUObased e ne propongono l

    The CT and MR imaging features of the main cardiac tumors will be reviewed. Cross-sectional imaging features may help differentiate between cardiac tumors and pseudo-tumoral lesions and identify malignant features. Based on clinical features, imaging findings are helpful to further characterize the nature of the lesion. CT and MR imaging can demonstrate the relationship of the tumor with adjacent anatomical structures and are invaluable in the pre-surgical work-up and post-surgical follow-up. (authors)

    Purpose. - Patients with permanent cardiac pacemakers occasionally require radiotherapy. Therapeutic Irradiation may cause pacemakers to malfunction due to the effects of ionizing radiation or electromagnetic interference. We studied the breast cancer patients who needed breast and/or chest wall and lymph node irradiation to assess the feasibility and tolerance in this population of patients. Patients and methods. - From November 2008 to December 2009, more than 900 patients received radiotherapy for their breast cancer in our department using megavoltage linear accelerator (X 4-6 MV and electrons). Among them, seven patients were with permanent pacemaker. All patients have been treated to the breast and chest wall and/or lymph nodes. Total dose to breast and/or chest wall was 50 Gy/25 fractions and 46 Gy/23 fractions to lymph nodes. Patients who underwent conserving surgery followed by breast irradiation were boosted when indicated to tumour bed with 16 Gy/8 fractions. All patients were monitored everyday in presence of radiation oncologist to follow the function of their pacemaker. All pacemakers were controlled before and after radiotherapy by the patients' cardiologist. Results. - Seven patients were referred in our department for postoperative breast cancer radiotherapy. Among them, only one patient was declined for radiotherapy and underwent mastectomy without radiotherapy. In four cases the pacemaker was repositioned before the beginning of radiotherapy. Six patients, aged between 48 and 84 years underwent irradiation for their breast cancer. Four patients were treated with conserving surgery followed by breast radiotherapy and two with mastectomy followed by chest wall and internal mammary chain, supra- and infra-clavicular lymph node irradiation. The dose to the pacemaker generator was kept below 2 Gy. There was no pacemaker dysfunction observed during the radiotherapy. Conclusion. - The multidisciplinary work with position change of the pacemaker before radiotherapy and everyday monitoring permitted the safe treatment of our patients. Updated guidelines are definitely needed with more details about acceptable doses at the different parts of the pacemaker. (authors)

    Nowadays, medical care development allows many people to share the benefits of implanted pacemakers (PM). PM can be perturbed and even fall in complete breakdowns in an electromagnetic and radiation environment. A stimuli-dependent patient can thus be seriously in danger. This article presents the effect of ionizing radiation from either a cobalt-60 source or from a linear accelerator (Saturne 43) on 12 pacemakers. It seems that technological progress make electronic circuits more sensitive to the cumulated dose of radiation. This survey shows that pacemakers have great difficulties to sustain ionizing radiation doses that are commonly delivered to patients during therapies. Usually perturbed functioning appears suddenly and means a strong shift of stimuli that might lead to heart failure.

    We studied the effects of the partial substitution (10%) of praseodymium by samarium and bismuth, on the structural, magnetic, magnetocaloric and electrical properties of the Pr0.63A0.07Sr0.3MnO3 (A=Pr, Sm and Bi) manganites prepared using the solid state reaction. Refinement of the X-ray diffraction patterns shows that all our samples are single phase and crystallize in the orthorhombic structure with Pnma space group. Magnetic studies indicate that all the samples exhibit a ferromagnetic-paramagnetic transition with increasing temperature. Curie temperature TC decreases by substitution. M(H) curves indicate the presence of some antiferromagnetic domains in the substituted samples testifying the phase-separated nature of these samples. The magnetic entropy curves -ΔS(T) show a maximum in vicinity of TC. Important values of maximum of -ΔS are recorded for our compounds. For the parent compound, we found 4.59 J/kg K for an applied magnetic field of 2 T at TC=266 K which raises the possibility of using this compound as a magnetic refrigerant. The temperature dependence of the electrical resistivity ρ(T) indicates that all compounds exhibit a metal-insulator transition with increasing temperature. Electrical study suggests the presence of a correlation between electrical and magnetic properties.

    Langasites have been studied extensively in past for their functional properties and use in telecommunication. A thorough understanding of their ground state is limited by the difficulty in synthesizing new members belonging to this series due to the formation of competing phases such as the garnets. Three magnetic langasites A{sub 3}Ga{sub 3}Ge{sub 2}BeO{sub 14} (A=Pr, Nd, and Sm) and a non-magnetic lattice standard La{sub 3}Ga{sub 3}Ge{sub 2}BeO{sub 14} were synthesized using the ceramic method. These were further characterized by X-ray diffraction, magnetization, magnetic susceptibility and heat capacity measurements. All three langasites exhibit net antiferromagnetic interactions at low temperatures and no evidence of long range magnetic ordering was observed down to 0.350 K. - Graphical abstract: Kagome network formed by the magnetic ions in the new Be-langasites. The ground states of three new members were explored using different physical property measurements such as X-ray diffraction, magnetization, magnetic susceptibility and heat capacity (a–d show refinement patterns for the langasites). These can be added to the list of candidate spin liquid materials. - Highlights: • Four new langasites A{sub 3}Ga{sub 3}Ge{sub 2}BeO{sub 14} (A=La, Pr, Nd, and Sm) were synthesized. • These were characterized using physical and magnetic property measurements. • These langasites exhibit net antiferromagnetic interactions at low temperatures. • No evidence of long range magnetic ordering was observed down to 0.350 K. • Can be potential Spin liquid candidates.

À première vue, cette affirmation se heurte à l’évidence d’une production littéraire quasi exponentielle autour de cette notion depuis plus d’une trentaine d’années, aussi bien en histoire de la philosophie que dans des travaux qui se sont efforcés de croiser la perspective phénoménologique avec les apports des sciences du cerveau et de la cognition. L’ennui est que cette ample littérature ne pose aucune des questions préjudicielles à l’adoption du concept de corps propre ou de chair (Leib en phénoménologie ; pour l’essentiel, elle fait comme si ce concept allait de soi et se borne à se demander de quelle manière il pourrait « féconder » des approches scientifiques plus positives.

Non seulement on ne se demande pas si les descriptions de cette « chair » au fil conducteur de l’expérience du toucher redoublé est tenable, mais on ne soulève même pas la question de savoir si l’adoption de ce concept chez Husserl et ses successeurs n’est pas conditionnée par des présupposés discutables et, en vérité, par tout un cadre théorique, de sorte que la mise en question de certains aspects centraux de ce cadre devrait conduire inévitablement à une révision en profondeur de ce concept. C’est cette question que nous voudrions aborder dans ces pages.

    Full Text Available Bronchoplastic techniques: Plastic-reconstructive techniques in thoracic surgery have led to significant reductions of morbidity and mortality. Particulary the so-called sleeve resections are now commonplace in non-small cell carcinoma in stage I–IIIA, with rather similar five-year survival as conventional resections. Even with infiltration of large vessels (T4-stage, this technique can be applied even in the curative approach, e.g., replacement of the pulmonary artery by a vascular prosthesis (“double sleeve resection”.Extended resection of the anterior and lateral chest wall: Malignant tumors of the chest wall are caused by infiltration of the so-called T3-carcinoma of the lung, by primary bone tumors (e.g., chondrosarcoma or by osseous metastases from extrathoracic malignancies (e.g., breast cancer. After “en bloc-resection” of the chest wall including the surrounding lung parenchyma, the large defect is covered by a muscle rotation flap (M. latissimus dorsi. Sometimes these muscle flaps can not be used, for example in cachexia. In these cases, the bony thoracic defect is reconstructed by a Goretex-patch (Goretex Dualmesh. Then the patient undergoes laparotomy or laparoscopy and dissection of the omentum of the great curvature of the stomach while preserving the right epiploic artery. Through a subcutaneous tunnel, the omentum is displaced to the thoracic wall to cover the Goretex-patch. To accelerate the wound healing, the omentum is covered with a polyurethane sponge, which is pressed with a suction of 125 mm Hg (vacuum therapy. At about 4 weeks, the healed omentum can be covered with a split skin graft.Intrathoracic infections: Severe thoracic infections (empyema, lung abscess are usually caused by a pneumonia (80% or are the consequence of operative complications (e.g., bronchial stump insufficiency.The infection is not curable with the conventional irrigation drains. Often the muscle rotation flaps fail, too. The combination of the transposed greater omentum and polyurethane sponges (VAC leads to a faster cleaning of the soiled thoracic cavity and accelerates the wound granulation. With this technique, even unfavourable cases could be rehabilitated.Sternal wound infections: The osteomyelitis of the sternum is a potentially life-threatening complication (mediastinitis, especially after cardiac surgery. In these cases, the vacuum therapy (VAC with polyurethane sponges have contributed to the improved prognosis. Firstly, a more rapid debridement is provoked, and second the chest wall will be stabilized more quickly, because the VAC reduces the shear forces in a dehiscence of the sternum. After reaching clean conditions, a muscle flap or the greater omentum are interposed for final wound closure.

    2012-12-01

    Full Text Available Modern plastic-reconstructive surgery, much like hand surgery, repres a young and fast-developing surgical discipline. The principles of plastic surgery originate in the developmental stages of surgery and have considerable influence on hand surgery. Microsurgery, free or pedicled transfer of tissue, peripheral nerve surgery, plexus surgery, tendon transfers, arthroplasty, vascularized bone transfers, or toe to thumb transplants, are all performed while considering plastic surgical principles and represent just a part of plastic surgical techniques which are daily applied in hand-surgical routine. They emphasize the intimate relationship and the mutual influence between the two disciplines. The future of plastic surgery is likely to include composite tissue allotransplantation, flap prefabrication, virtual surgical planning, application of growth factors to influence bone growth, fracture healing, angiogenesis, tendon healing or wound healing. Furthermore, the field of tissue engineering is likely to introduce novel materials, such as nerve conduits. All of the above may have direct influence on hand surgery and, therefore, the future of plastic and hand surgery is at least as intricately intertwined as was their past. They will remain related through the characteristics that led to their development: innovation, creativity, diversity and the search for individualized solutions.

  11. Tomographie par coherence optique pour le guidage de chirurgies minimalement invasives du rachis

    Science.gov (United States)

    Beaudette, Kathy

    Adolescent idiopathic scoliosis is a complex 3D deformity of the spine which requires surgical intervention in severe cases of the condition. The existing corrective procedure of scoliosis is very invasive; it involves a long incision and a large instrumentation, in addition to the fusion of a section of the spine. To improve postoperative conditions and to preserve patients' spinal flexibility, novel fusionless surgical approaches involving growth modulation are under investigation. With this objective in mind, a multidisciplinary team from École Polytechnique of Montreal and Sainte-Justine University Hospital Research Center is developing a surgical technique based on the insertion of micro-staples between vertebral growth plates and corresponding intervertebral disks. Each micro-staple passively modulates the vertebral growth on the convex side of the scoliotic curvature. This modulation modifies vertebral geometry which, for scoliotic patients, presents a wedging deformity. The modulation induced by these devices could lead to the correction of the curvature of the spine. This innovative procedure would preserve the flexibility of the spine as well as the health of intervertebral disks, in addition to being compatible with minimally invasive approaches. However, to be efficient, the micro-staples must be placed at the junction between the growth plate and the disk with a sub-millimeter precision. An intraoperative guiding system is therefore required to ensure the success of the intervention. Optical coherence tomography (OCT) is a promising candidate for this application. OCT is based on low-coherence interferometry and provides cross-sectional images with a resolution about 10 μm for a depth of 2 to 3 mm. This technique allows for the real-time acquisition of images and is compatible with endoscopy, thereby showing a potential for the intraoperative guidance of minimally invasive surgeries (MIS) of the spine. The main objective of this master's project is therefore to evaluate the possibility of using OCT to localize as well as identify spinal structures (such as growth plates, osseous tissue, intervertebral disks and connective tissue) and to guide the insertion of micro-staples. To attain this objective, an OCT handheld probe was designed and developed according to the surgical constraints of MIS performed by thoracoscopy (through the thorax). This probe has an external diameter of 17 mm and is 30 cm long. Coupled with a fibered interferometer, the axial and lateral resolutions of the probe are of 16 and 27 μm respectively. The OCT probe was used in vivo during an open surgery on a porcine model. Different tissues within the operative window (lung, muscles, osseous tissues and intervertebral disk) were imaged during the procedure. These preliminary in vivo tests demonstrated that the probe is capable of identifying different types of tissue with a good sensitivity and an adequate penetration depth. These results also showed that a visual inspection of the in vivo OCT images alone is not sufficient to localize the growth plates on the vertebrae. An ex vivo study using porcine vertebrae was therefore performed to identify quantitative markers in order to facilitate the interpretation of in vivo OCT images. OCT images were initially compared to corresponding histological sections. The ensuing results showed that the connective tissue layer presents a band pattern due to the birefringence properties of the collagen-rich tissue. The intervertebral disk was also shown to have a characteristic lamellar structure on OCT images. Lastly, within growth plate and osseous tissue locations, the OCT signal decay is monotonic, but with different attenuation coefficients (different slopes). Relative attenuation coefficients were therefore measured for each tissue (growth plate, osseous tissue, connective tissue and intervertebral disk) on several specimens and were compared. These results showed that growth plates present an average relative attenuation coefficient statistically different from the other tissues. An automatic growth plate segmentation algorithm was then developed and tested. The algorithm was applied to images from an ex vivo specimen of a porcine vertebra and successfully identified most of the growth plate (> 75%) amidst the osseous tissue of the vertebral body and the intervertebral disk. This master's project shows that OCT presents contrast, resolution and penetration depth that are sufficient for the identification of musculoskeletal structures of the spine. It is thus reasonable to believe that, ultimately, OCT could be used for the intraoperative guiding of the insertion of micro-staples during corrective surgeries of scoliosis.

    Full Text Available The Art of Surgery has a very long tradition and is one of the earliest treatments for serious injuries of diverse causes. Due to achievements in anesthesia and intensive care medicine in the second half of the nineteenth century, postoperative morbidity and mortality have been appreciably reduced. Operative techniques could be expanded and new operative therapies could be introduced. Although the last two-hundred years have brought about increasing specialization in medicine and operative specialties have developed in multiple areas, the operative spectrum of the visceral surgeon has remained rather broad and diverse. Numerous operative procedures are carried out in the entire gastroi tract as well as the body surface. Many of these are to treat diseases, while others are of help in the plastic reconstruction of organs and the body surface. Thanks to specialization, among the positive developments are shortened operation time and length of hospital stay, as well as reduced postoperative morbidity and mortality. The advances in minimal-invasive surgery and the progress in surgical instruments and suturing techniques are some origins of these positive developments. This article cannot cover all possible resections and reconstructions of the visceral surgeon, but will instead concentrate on two major sites. The operative treatment of inguinal hernias is one of the oldest operations known to humanity. Because hernias are one of the most common operations of all visceral surgical procedures, their surgical therapy shall be particularly highlighted here. But the plastic and reconstructive possibilities of the visceral surgeon are by no means limited to hernia repair. So this manuscript will further provide insight into the resection and reconstruction possibilities of the esophagus, one of the most challenging procedures in this field.

    The aim of the present study was to assess the prevalence and resistance of commensal S. aureus in the nasal microbiota of community-dwelling persons in Austria, as well as to identify possible associations with socio-demographic factors. Multi-drug resistance in this population was additionally studied. This cross-sectional study was conducted within the context of the European APRES project. In nine European countries, nasal swabs were collected from 32,206 general practice patients who received care for non-infectious reasons. In Austria, 20 GPs attempted to recruit 200 consecutive patients without infectious diseases, with each patient completing demographic questionnaires as well as providing a nose swab sample. Isolation, identification, and resistance testing of S. aureus were performed. Statistical analyses included subgroup analyses and logistic regression models. 3309 nose swabs and corresponding questionnaires from Austrian subjects were analyzed. S. aureus was identified in 16.6 % (n = 549) of nose swabs, of which 70.1 % were resistant against one or more antibiotics, mainly penicillin. S. aureus carrier status was significantly associated with male sex (OR 1.6; 1.3-2.0), younger age (OR 1.3; 1.0-1.8), living in a rural area (OR 1.4; 1.1-1.7) and working in the healthcare sector (OR 1.5; 1.0-2.1). Multi-drug resistances were identified in 13.7 % (n = 75) of the S. aureus carriers and 1.5 % (n = 8) tested positive for MRSA. The highest resistance rate was observed against penicillin (64.8 %), followed by azithromycin (13.5 %) and erythromycin with 13.3 %. This study describes the prevalence and resistance patterns of commensal S. aureus in community-dwelling persons in Austria and shows that differences exist between socio-demographic groups. Demographic associations have been found for S. aureus carriers but not for carriers of resistant S. aureus strains. Only two thirds of S. aureus strains were found to be resistant against small spectrum penicillin

    Full Text Available Dans les carrières de roches massives abandonnées après l'exploitation, l'aridité du sol et le caractère oligotrophe du milieu, conjugués à la présence de parois rocheuses et de plans d'eau au niveau des excavations les plus profondes, sont des éléments favorables à l'expression d'une biodiversité renouvelée et originale. Un inventaire écologique mené sur la carrière de quartzite de Cheffois, située dans le sud du Massif Armoricain, a révélé la richesse biologique de ce type de milieu semi-naturel. Les résultats de l'inventaire ont conduit à distinguer six types d'habitats néoformés correspondant à d'anciens secteurs d'exploitation : (1 un plan d'eau de fosse, (2 une zone de carreau humide, (3 une zone de carreau sec, (4 des fronts de taille d'expositions variées, (5 des remblais boisés, et (6 une galerie souterraine. Ces six types de milieux sont eux-mêmes subdivisés en une mosaïque de petits habitats, favorisant au final une grande biodiversité avec le développement de nombreuses espèces végétales et animales, dont certaines à forte valeur patrimoniale. Replacé dans le contexte du Bas-Bocage vendéen, l'apport écologique de la carrière de quartzite est évalué et confronté aux pertes en biodiversité engendrées par l'ouverture de la carrière. Avec les autres carrières de quartzite situées sur les sites rocheux des environs, elles constituent, ensemble, un réseau de carrières partiellement inondées pouvant contribuer à la création d'un véritable corridor écologique, dans une matrice bocagère actuellement en perte de biodiversité.In abandoned quarries of massive rocks, the aridity and oligotrophic character of soils, combined with the presence of rock walls and water bodies in the deeper excavations, are favourable to the expression of a renewed, original biodiversity.

    The influence of titanium and zirconium additions on the heterogeneity texture of Al-Fe-Ni alloys, and the resultant effect on their corrosion resistance, is briefly recalled. The present article records the results of corrosion tests on these alloys after prolonged heat treatment. Without additions, the eutectic structure of the basis alloy is subject to a coalescence, which results in a deterioration of corrosion resistance. This effect applies equally to the as-cast and to the wrought conditions. The addition of titanium or zirconium retards this deterioration very considerably, both for the as-cast and wrought alloys. (author) [French] Apres un rappel de l'influence la texture d'heterogeneite sur la tenue a la corrosion, et du role joue par les additions de titane et de zirconium sur cette texture, il est rapporte dans le present travail les resultats d'essais de corrosion apres ces chauffages de longue duree. Pour l'alliage de base, la coalescence de l'eutectique dans l'etat de fonderie comme dans l'etat corroye, suivie micrographiquement, s'accompagne d'une degradation sensible de la tenue a la corrosion. Les additions de zirconium et de titane retardent tres fortement cette degradation, qu'il s'agisse encore de la texture de fonderie ou de celle de corroyage. (auteur)

    Full Text Available Winter sports occupy a prominent place in European tourism, not only because of their economic importance in mountainous areas but also due to their major symbolic significance in the "leisure civilisation". Yet the world of winter tourism is full of uncertainties connected with climate change and also with evolutions and structural breaks that call into question the development model on which it is based. This context of profound change gives us the opportunity to question the limits of the industrial model that has governed the development of the Alps for the practice of skiing and to examine alternative future scenarios to "all-out skiing" and even "all-out tourism".Les sports d’hiver occupent une place de premier plan dans le tourisme européen, non seulement du fait de leur poids économique dans les régions de montagne, mais aussi par leur forte dimension symbolique dans la « civilisation des loisirs ». Pourtant l’univers du tourisme hivernal est parcouru par de nombreuses incertitudes liées au changement climatique, mais aussi à des évolutions et des ruptures structurelles qui remettent en question le modèle de développement sur lequel il repose. Ce contexte de mutation permet d’interroger les limites du modèle industriel qui a présidé à l’aménagement des Alpes pour la pratique du ski et d’examiner des figures d’avenir alternatives au « tout ski » et même au « tout tourisme ».

    Objective In order to improve the in vivo gene transfer into the heart muscle, we have designed a ECG-synchronized microinjection system that allows sequential gene delivery to the myocardium.Methods A cannula was introduced into the right carotid artery of the Wistar rat under general anesthesia.With the ECG-synchronized injection during diastole, the genetic vector (Ad CMV lacZ ) infusion was performed with various concentrations( l07 ~ l010pfu ) and different frequency ( the ratio of heart beats per injection from 1: 1 to 4: 1 ). The hearts of the rats were removed after 7 days for histological examination. Results Best results were obtained with a total vector amount of l09 pfu and a good ratio 3: 1 between heart frequency and injection frequency. The transfection efficiency was increased by use of vasodilators and by an increase of vascular permeability. No signs of myocardial ischemia or ventricular arrythmia were observed. Conclusion We have established a novel and safe method for in vivo gene transfer into the heart. Transgene expression suggests that this method may be useful technique to study cardiac function of treat cardiac diseases by means of gene theratpy.

    Cardiac kinetics analysis is of a great diagnostic interest in the fight against cardiovascular pathologies. Two methods are proposed in order to estimate cardiac motion from dynamic sequences of three-dimensional volumes acquired in multislice computed tomography. These methods both lie on a feature matching process, carried out within a Markovian framework and according to a multi-resolution scheme. The first method, estimating the correspondences between pre-segmented surfaces, is dependent on the temporal coherence of this segmentation. The second method estimates the correspondences between, on the one hand, a segmented surface and, on the other hand, the original data volume corresponding to the next moment. The motion estimation and the segmentation are then carried out, on the whole sequence, during a single process. Both methods are validated on simulated and real data. (author)

    édisaient de façon significative le recours au bronzage artificiel, notamment l’occupation d’un emploi à temps partiel, l’activité physique, l’adoption de divers comportements à risque comme conduire un véhicule sous l’emprise de l’alcool (chez les garçons et le fait d’avoir des relations sexuelles non planifiées après avoir consommé de l’alcool ou de la drogue (chez les filles, être victime de commentaires négatifs sur sa silhouette, sa taille ou son apparence, se déclarer comme transgenre ou d’un autre genre, consommer de la créatine ou autres suppléments et, pour les filles, utiliser rarement ou ne jamais utiliser de protection solaire. Conclusion : Le bronzage artificiel chez les adolescents a été associé à l’âge, au travail à temps partiel, à l’activité physique et à de nombreux comportements de consommation et de facteurs de risque liés au mode de vie. Même si la législation interdisant l’accès des adolescents aux salons de bronzage est essentielle, les activités de promotion de la santé visant à décourager le bronzage artificiel pourraient porter davantage fruit si elles s’attaquaient aussi à ces facteurs connexes.

    Nowadays, more and more surgical interventions are carried out in Minimally Invasive Surgery, to make the post-operative constraints less painful for the patient. Actually, new surgical tools or medical products are designed after informal discussions between surgeons and designers. The user requirements documents are the main document used by the mechanical designers to design and improve the product. Medical terms, often used by surgeons and employed to explain their needs, don't allow for an instantaneous understanding by designers. Unfortunately, this relation causes a dysfunction in the definition cycle of the product. Our aim is to work on the design process, its assistance thanks to methods and tools and on its organisation for better understandings and more complementarities between surgeons and designers. We propose on this article a design method already tested in the informatics domain: User Centred Design which takes the user into account more effectively in the process design.

Au départ un réseau décentralisé qui lie les gens sans intervention politico-hiérarchique, Facebook est mobilisé par les hommes politiques au service de leur besoins. Quelles en sont les conséquences pour la sphère publique : s’agit-il d’un outil qui permet à l’internaute de déjouer les usages de marketing politique qu’en fait l’homme politique ?The purpose of this article is to show how social networks, and more specifically Facebook, are used by politicians and their supporters. This is achieved through a detailed analysis of exchange of posts between politicians and surfers in the period following the presidential election campaigns in France of 2007. It is shown how politicians take advantage of Facebook, despite its initially being a decentralized social network, connecting people without a political or hierarchic purpose. The article attempts to show some of the consequences of such an exploitation of a public network for the public sphere and asks how much leverage there is for the surfers/citizens in moderating political marketing on Facebook.

    Fa Lin, Wang Lei, Zheng Yajuan, Zhang Qi and Zhang Xiaohu. The application of acoustics in oil logging and geophysical exploration. PI. 2012,26 (2): 1-6 By using the method of acoustic-electric analogue, this paper sets up the equivalent circuits of acoustic transducer, and gives the relationship between the acoustic-signal radiated by the source-transducer and the driving-voltage signal and that between the acoustic-signal and electric-signal converted from the receiver-transducer. This paper employs the convolution of the driving-voltage signal with the electric-acoustic impulse response of the source-transducer to replace some assumed acoustic-source functions adopted in previouly published literature on acoustic logging, such as Tsang wavelet and so on. In this paper the concept and theory of signal transmission is used to analyze the total acoustic- logging process, and the acoustic-logging transmission network model is set up. This model sets up the theoretical basis for accurate measurements of propagation speed, phase, amplitude and frequency information of acoustic-logging signal. The development of a new device, Kaiser in-situ stress system is introduced. This device is designed to measure in-situ stresses via detected acoustic emissions caused by the Kaiser effect in rocks. The system provides a technical means for both the economic and efficient evaluation of the three principal stresses in rocks. This is useful to assess the in-situ stress field in oil and gas reservoirs and to predict natural geology hazard. A new algorithm of inversion oil reservoir by using logging data and seismic exploration date is also described.

    2012-06-01

    Full Text Available Witold Wachowski’s brief exchange with John Zorn provides us with many valuable insights relating to the composer’s aesthetic. Zorn’s professed antipathy towards audiences, his faith in the creative instinct of the “artist,” and his belief in the transcendental nature of musical works (as a gateway into a world of “truth” and “beauty” are all refrains commonly encountered in many interviews with the composer. Given the fact that Zorn emphasizes these themes in his very short interview with Wachowski, we can assume that these ideas form the core of Zorn’s musical and artistic aesthetic. For any person with even a basic knowledge of Western aesthetic traditions, however, these same aesthetic features and positions characterize musical institutions common to the Western art tradition, particularly the “romantic” ideal of music and composers that developed in the nineteenth century. Philosophers (most notably Hegel and Kant along with music critics and composers (such as Friedrich Schiller, E.T.A. Hoffmann, Friedrich Schlegel, Robert Schumann, and Eduard Hanslick all contributed to the development of a romantic musical aesthetic in the nineteenth century that emphasized the role of the artist (as a “genius” or “god-like” who created “works” that – through purely musical relations that exist irregardless of the listener’s abilities – reveal hidden worlds of truth and beauty, worlds far-removed from the humdrum concerns of daily existence. Given the close (nearly one-to-one correspondences between Zorn and aestheticians/philosophers of the nineteenth century, one could make the argument that Zorn holds a “romantic” view of music and art.

The preventive measures taken to limit the internal contamination of the inhabitants are difficult to implement and maintain because of the invisibility of radioactivity, the flourishing surrounding nature, time passing and the lack of danger awareness of the new inhabitants. The poor standard of population health is due to aging (cancers and cardiovascular diseases), to the impact of radioactive contamination (thyroid cancer among the young) but is aggravated by the very low standard of living (tuberculosis is spreading). The local economy collapsed when 50% of the land were banned from any farming activity because of the radioactive contamination, another important resource was the forest but today a large part of wood is unfit for being sold or used as firewood. On the other hand the management of contaminated areas has driven up the production costs. (A.C.)

    This is an annual report, regularly issued by IPSN, that presents the ecological and health consequences of the Chernobyl Nuclear Accident. The present status of the Chernobyl Nuclear Plant, which Ukraine engaged to stop definitively in year 2000, is summarized. The only reactor unit now in operation is Chernobylsk-3 Reactor which poses two safety questions: evolution of cracks in part of the tubing and behaviour of the pressure tubes. Although, some improvements in the RBMK reactor types were introduced, problems remain that make IPSN to stress the requirement of stopping this NPP completely. In the contaminated territories surrounding Chernobyl incidence rate of infant thyroid cancers continues to grow, reaching values 10 to 100 times higher than the natural rate. In France the IPSN analyzed 60,000 records carried out in 17 sites during May 1986 and April 1989. It was estimated that the individual dose received during 60 years (1986-2046) by the inhabitants of the most affected zone (eastern France) is lower than 1.5 mSv, a value lower than 1% of the natural cosmic and telluric radioactivity exposure for the same period. For the persons assumed to live in the most attacked forests (from eastern France) and nourishing daily with venison and mushrooms the highest estimate is 1 mSv a year. Concerning the 'hot spots', identified in mountains by IPSN and CRIIRAD, the doses received by excursionists are around 0.015 mSv. For an average inhabitant of the country the dose piled up in the thyroid due to iodine-131 fallout is estimated to 0.5-2 mSv for an adult and 6.5-16 mSv for an infant. These doses are 100 to 1000 times lower than the ones to which the infants living in the neighbourhood of Chernobyl are exposed to. The contents of the report is displayed in the following six chapters: 1. Chernobyl in some figures; 2. The 'sarcophagus' and the reactors of the Chernobyl NPP; 3. Health consequences of the Chernobyl accident;. 4. The impact of Chernobyl fallout in France; 5. Chernobyl's environment and the management of contaminated territories.; 6.

    La précipitation qui se produit lors de vieillissements de longue durée entre 450 et 700°C dans un acier 316 Ti soit hypertrempé soit écroui, a été étudiée en couplant les techniques de microscopic électronique et de microanalyse X. Pour les cas expérimentaux étudiés, les résultats obtenus montrent que la composition des carbures M 23C 6 et des phases σ, Laves et χ est peu sensible aux conditions de vieillissement et dépend également peu de l'état structural initial. Leur teneur en éléments principaux de l'alliage est d'ailleurs voisine de celle des phases précipitées dans l'acier non stabilisé. Excepté les carbures de type M 6C, toutes ces phases ont une teneur en nickel inférieure à celle de la matrice. Les premiers rérultats obtenus sur des matériaux irradiés aux neutrons montrent que la précipitation sous flux est différente de celle qui se produit dans l'acier vieilli. Les phases γ' et G ainsi que les carbures riches en nickel ont été observés. L'attention a été attirée sur le fait qu'il n'y a pas de corrélation simple entre la vitesse de gonflement et la teneuer résiduelle en nickel de la matrice.

    Congestive heart failure is a often associated with an impairment of sympathetic nervous system, i.e., global hyperactivity and regional impairment of adrenergic system. Cardiac {sup 123}I-meta-iodo-benzyl-guanidine (M.I.B.G.) scintigraphy is a radionuclide technique which can explore the presynaptic adrenergic function. Cardiac fixation of M.I.B.G. is decreased in congestive heart failure, reflecting a reduction of norepinephrine uptake by the myocardial presynaptic ending nerves. The impairment of presynaptic function is early and actually involved in the pathogenesis of cardiac failure. Cardiac M.I.B.G. scintigraphy is a useful tool to explore the myocardial adrenergic stores in patients with congestive heart failure. (authors)

    Purpose. - To assess the value of treatment-planning related parameters namely, the breast volume; the distance of the inferior field border to diaphragm; and the cardio-thoracic ratio for left-tangential breast irradiation. Patients and methods. - Treatment plans of 27 consecutively left-sided breast cancer patients after breast conserving surgery were evaluated for several parameters concerning heart-irradiation. We measured the heart distance respective to the cardio-thoracic ratio and the distance of the inferior field border to diaphragm, as well as the breast volume in correlation with the irradiated heart volume. Results. - The mean heart and left breast volumes were 504 cm{sup 3} and 672.8 cm{sup 3}, respectively. The mean heart diameter was 13.4 cm; the mean cardio-thoracic ratio 0.51 and the mean distance of the inferior field border to diaphragm was 1.4 cm. Cardio-thoracic ratio (p = 0.01), breast volume (p = 0.0002), distance of the inferior field border to diaphragm (p = 0.02) and central lung distance (p = 0.02) were significantly correlated with the measured heart distance. A significant correlation was also found between cardio-thoracic ratio, breast volume and distance of the inferior field border to diaphragm with the irradiated heart volume measured by V10, V20 and V40. Conclusion. - The verification of parameters like cardio-thoracic ratio, distance of the inferior field border to diaphragm and breast volume in left-sided breast cancer patients may help in determining which patients could benefit from more complex planning techniques such as intensity-modulated radiotherapy to reduced risk of late cardiac injury.

    Full Text Available Comme c’est le cas dans l’ensemble du monde arabe, les autobiographies politiques yéménites contemporaines ont connu un véritable essor depuis les années 1980, et peuvent constituer des sources documentaires que l’historien ne saurait négliger. S’insérant dans le cadre d’une étude plus large sur la façon dont la présence ottomane (1872-1918 a été perçue au Yémen avant et après le retrait ottoman, cet article montre cependant combien cette partie de l’histoire yéménite est encombrante dans la mémoire des acteurs de la révolution républicaine de 1962. Le credo de l’indépendance acquise contre la vilénie turque, thème que l’imamat contemporain (1904-1962 a su habilement partager avec l’idéologie nationaliste arabe dont se sont réclamés les révolutionnaires, aura sans doute créé un paradoxe insurmontable. Les quelques neuf auteurs d’autobiographie ici recensés, tous anciens révolutionnaires, font en effet preuve d’une amnésie particulière lorsqu’ils relatent leur parcours et celui de leur père, limitant la présence ottomane à un simple élément du décor historique. L’article interroge donc les non dits et les oublis des auteurs, et explore les mécanismes du récit autobiographique pour montrer que les indices d’une autre histoire peuvent apparaître dans ses marges, lorsque la cohérence de l’histoire familiale et de l’expérience individuelle n’est pas en jeu : la mémoire se heurte à l’histoire, où le modèle ottoman a permis, au Yémen, d’imaginer un autre avenir.As is the case all over the Arab World, contemporary Yemeni political autobiographies have been booming ever since the 80's, and can be used as a source for material which no historian should overlook. Part of a broader study on how the Ottoman presence (1872-1918 was perceived, both before and after pulling out of Yemen, this article however shows how "cumbersome" this part of Yemen's history can be in the

    I-123 MIBG cardiac scintigraphy is a useful tool to assess cardiac adrenergic neuronal function, which is impaired in children with dilated cardiomyopathy (DCM). In adults with DCM, long-term treatment with carvedilol improves both cardiac adrenergic neuronal function and left ventricular function. The aim of this prospective study was to evaluate the impact of carvedilol on cardiac adrenergic neuronal function and on left ventricular function in seventeen patients (11 female, 6 male, mean age 39 {+-} 57 months, range 1 - 168 months) with DCM. All patients underwent I-123 MIBG cardiac scintigraphy and equilibrium radio-nuclide angiography before and after a 6 month period of carvedilol therapy. A static anterior view of the chest was acquired 4 hours after intravenous injection of 20 to 75 MBq of I-123 MIBG. Cardiac neuronal uptake of I-123 MIBG was measured using the heart to mediastinum count ratio (HMR). Radionuclide left ventricular ejection fraction (LVEF) was assessed following a standard protocol. There was no major cardiac events (death or transplantation) during the follow-up period. I-123 MIBG cardiac uptake and left ventricular function respectively increased by 38% and 65% after 6 months of treatment with carvedilol (HMR 223 {+-} 49% vs 162 {+-} 26%, p < 0.0001 and LVEF = 43 {+-} 17% vs 26 {+-} 11%, p < 0.0001). Carvedilol can improve cardiac adrenergic neuronal function and left ventricular function in children with DCM. Further studies are needed to assess the relationship between improvement in I-123 MIBG cardiac uptake and the beneficial effects of carvedilol on morbidity and mortality. (authors)

L’âge gestationnel au moment du diagnostic du cancer était respectivement de 7; 21 et 25 semaines. Il s'agissait de stade IV et IIIA respectivement dans deux et un cas. Elles ont toutes bénéficié d'une chimiothérapie dans deux cas pendant la grossesse (6TEC et 3AC) et dans un cas après l'accouchement. Une mastectomie bilatérale a été réalisée dans un cas. Une patiente est décédée. Les autres étaient vivantes mais toutes métastatiques. Une hypotrophie fœtale a été notée dans un cas. Le diagnostic du cancer est tardif dans cette association. La chirurgie est faisable et le type de chirurgie serait seulement fonction du stade du cancer. La chimiothérapie est possible avec moins de complications fœtales aux deux derniers trimestres.

    Among the different options recommended for high-risk prostate cancer, radical prostatectomy is admitted as radiotherapy, but its role is still controversial in mono-therapy and difficult to evaluate in combined treatments. The results of clinical trials combining an external radiotherapy to a long-term androgen deprivation in locally advanced tumours sustain the principle of a multidisciplinary management in high-risk prostate cancer. The impact of surgery on the risk of progression and local recurrence is important in selected patients with low grade and small tumoral volume. Clinical and histological data associated to the MRI assessment remain essential and enhance the preoperative multidisciplinary decision, especially regarding nodal and distant metastases. Radical prostatectomy with an extended pelvic lymphadenectomy can be considered as a viable alternative to radiotherapy and hormonal therapy in these patients with a long life expectancy but presenting a high risk of local progression and a low risk of metastatic disease. Morbidity of the procedure is similar to radical prostatectomy for organ-confined tumours despite more erectile dysfunction due to non-sparing radical prostatectomy in most of cases. Oncological results from recent compiled series show 10- and 15-year specific survival rates around 85 and 75%, respectively, including adjuvant or salvage treatments with radiotherapy, androgen deprivation or chemotherapy.

    Nephron-sparing surgery of renal cell carcinoma in the 1970's and 1980's in patients with bilateral renal tumors or reduced renal function (imperative indication) has shown a very low risk of recurrent cancer. Today, nephron-sparing surgery in renal cell carcinoma is considered in an increasing number of patients with expected sufficient renal function after nephrectomy (elective indication). Resection technique, the use of Tabotamp trademark to reduce bleeding, and pseudotumors do complicate the interpretation of the images. It has been not yet defined which diagnostic modality is best suited for follow-up after renal cell carcinoma resection. Follow-up protocols in different institutions show a wide variety. The follow-up of patients after nephron-sparing surgery is performed by annual sonography or MRI every three months. Up to now, CT and ultrasound are the standard methods. MRI with its multiplanar imaging and improved soft tissue contrast seems to have an equal diagnostic value. Additionally, MRI seems to be suited for patients with reduced renal function. The aim of this paper is to give guidelines for the radiologist to understand the different surgical procedures and to evaluate the post-operative findings. Different imaging modalities in the follow-up of patients and special radiological phenomena are discussed. (orig.) [German] Die Nachuntersuchungen der in den 70er und 80er Jahren des vergangenen Jahrhunderts organerhaltend operierten Patienten mit beidseitigen Nierenzellkarzinomen oder eingeschraenkter Nierenfunktion der Gegenseite (imperative Indikation) zeigten eine sehr niedrige Rezidivrate. Heute wird die organerhaltende Operation von Nierentumoren zunehmend auch bei den Patienten in Erwaegung gezogen, deren Nierenfunktion nach der Tumornephrektomie der betroffenen Niere noch ausreichen wuerde (elektive Indikation). Spezielle Operationstechniken wie die Verwendung von Tabotamp trademark zur Blutstillung und die Bildung von Pseudotumoren erschweren die Interpretation der Befunde. Fuer die Nachsorge nach organerhaltender Operation existiert bisher kein Standard. Der Umfang der radiologischen Nachsorge an den unterschiedlichen Institutionen reicht von Kontrollsonographien einmal im Jahr bis hin zu vierteljaehrlicher Magnetresonanztomographie (MRT). Die Computertomographie (CT) wird, neben dem Ultraschall, als Standardmethode fuer die Nachsorge nach Resektion angesehen. Die MRT eroeffnet durch die multiplanare Darstellung und ihren besseren Weichteilkontrast eine gleichwertige Diagnostik. Gleichzeitig erscheint die MRT fuer die Patienten mit Einzelniere und eingeschraenkter Nierenfunktion ueberlegen. Die folgende Uebersichtsarbeit soll die gaengigen Operationstechniken und die damit verbundenen postoperativen Befunde in der Bildgebung von CT, MRT und Sonographie vermitteln. (orig.)

    Full Text Available Les tumeurs desmoides sont des tumeurs rares des tissus mous qui peuvent être très agressives localement. A travers l’expérience de notre service, nous analyserons les résultats du traitement chirurgical de ces tumeurs. De 1980 à 2008, 12 patients ont été opérés pour tumeur desmoide de la paroi thoracique. Le diagnostic a été suspecté sur la base des signes cliniques et radiologiques. Aucun patient n’avait un syndrome de Gardner. L’abord chirurgical a été souvent électif à l’aplomb de la tumeur. La résection a été complète dans 11 cas. La confirmation diagnostique a été apportée par l’étude histologique de la pièce opératoire. La durée du suivi post opératoire variait entre 24 et 180 mois. Une patiente était décédée par insuffisance cardiaque et rénale. 7 cas avaient récidivé, et qui ont été traités par simple résection complète dans 5 cas, dont un avait nécessité une greffe myocutanée ; par ailleurs, deux cas ont été traités par résection incomplète associée à une radiothérapie adjuvante. La chirurgie des tumeurs desmoides de la paroi thoracique doit être aussi large que possible pour diminuer le risque de récidive.

    This research has resulted in four separate projects. The first was the exposure of Fischer 344 rats to JP-8 jet fuel for 7 or 28 days. This exposure resulted in changes in pulmonary function and lung chemical mediators, specifically Substance P, after 28 days of exposure. The second project dealt with blocking the increase in SP in these rats by a pretreatment regimen with capsaicin before jet fuel exposure. Capsaicin caused a further increase in lung permeability and a million-fold increase in airway sensitivity to histamine after the 7-day jet fuel exposure. The third project dealt with the effects of a 7-day jet fuel exposure in congenic mice who are deficient in the inducibility of the aryl hydrocarbon hydroxylase enzyme. These mice are relatively resistant to the effects of jet fuel-induced lung injury. The fourth project investigated the effects of the jet fuel exposure on secondary organs, specifically the liver, spleen, and kidneys. There were pathological differences in the liver, spleen, and kidneys between the 7-day jet fuel exposure group and baseline controls. However, some of these differences were not apparent in the 28-day exposure group, possibly indicating compensatory mechanisms to the exposure.

Pourtant l’univers du tourisme hivernal est parcouru par de nombreuses incertitudes liées au changement climatique, mais aussi à des évolutions et des ruptures structurelles qui remettent en question le modèle de développement sur lequel il repose. Ce contexte de mutation permet d’interroger les limites du modèle industriel qui a présidé à l’aménagement des Alpes pour la pratique du ski et d’examiner des figures d’avenir alternatives au « tout ski » et même au « tout tourisme ».Winter sports occupy a prominent place in European tourism, not only because of their economic importance in mountainous areas but also due to their major symbolic significance in the "leisure civilisation". Yet the world of winter tourism is full of uncertainties connected with climate change and also with evolutions and structural breaks that call into question the development model on which it is based. This context of profound change gives us the opportunity to question the limits of the industrial model that has governed the development of the Alps for the practice of skiing and to examine alternative future scenarios to "all-out skiing" and even "all-out tourism".

    Coronarography and tomo-scintigraphy (SPECT, Single Photon Emission Tomography) are two imaging techniques used broadly for the diagnosis of cardiovascular diseases. The first modality consists of X-ray image sequences visualizing each, in a same plane, the coronary arteries located on the front and the back side of the heart. The X-ray images give anatomical information relating to the arterial tree and highlight eventual artery narrowing (stenoses). The SPECT modality (nuclear imaging) provide a 3-dimensional (3D) representation of the myocardial volume perfusion. This functional information authorizes the visualization of myocardial regions suffering from irrigation defaults. The aim of the presented work is to superimpose (in the 3D space) the functional and anatomical information in order to establish the visual link between arterial lesions and their consequence in terms of irrigation defaults. In the 3D representation chosen to facilitate the diagnosis, the structure of a schematic arterial tree and the stenoses are placed onto the perfusion volume. The initial data consist of a list of points representative for the arterial tree (start and end points of arterial segments, bifurcations, stenoses, etc) and marked by coronary-graphs on the X-ray images of the different incidences. The perfusion volume is then projected under the incidences of the coronary-graphic images. A registration algorithm superimposing the X-ray images and the corresponding SPECT projections provides the parameters of the geometrical transformations bringing the points marked in the X rays images in equivalent positions in the 2-dimensional SPECT images. A 3D reconstruction algorithm is then used to place the arterial points and the stenoses on the perfusion volume and build a schematic tree acting as landmark for the clinician. A 28 patient database was used to realize 40 3D superimposition of anatomical-functional data. These reconstructions have shown that the 3D representation is precise enough for the establishment of the visual relationship between stenoses and perfusion defaults. (author)

    This work of thesis joins within the framework of an analysis of the sanitary consequences of the nuclear accident of Chernobylsk. Since 2005, the I.R.S.N. is interested in the not cancerous pathologies (cataracts, and cardiac arrhythmias) observed among the children living on the contaminated territories after the fallout of Chernobylsk and has in this aim implemented a research programme called E.P.I.C.E. (Evaluation of the pathologies induced by a chronicle contamination by cesium) whom objective is to show an eventual link between the chronicle ingestion of contaminated food and these pathologies emergence. An exploitation of the results of the pilot study,first phase of the E.P.I.C.E. program was realized. The analysis was completed by two bibliographical reviews relative to the knowledge available on these diseases. The results of this pilot study suggest: on one hand, an absence of link between the activity in cesium 137 at the level of the heart, of the whole body and the emergence of disorder of the heart rhythm; on the other hand, for the cases of cataract, a link between the load in cesium 137 at the neck level and the emergence of the disease in 40 % of the cases. However, these results must be considered with caution because several limits and, in particular, a way of selection affect this study. concerning the scientific literature, this one stays rather poor because only thee articles make reference to a relationship between cesium 137 and the emergence of these non cancerous pathologies. After having exposed the context, this thesis draws up the situation of knowledge relative to cataracts and to cardiac arrhythmias and their possible relationship with ionizing radiations, collect the results stemming from the analysis of the pilot study and envisages future epidemiological studies.

    During the last few years, cardiac imaging made important breakthroughs thanks to the development of various techniques allowing the risk stratification of patients with coronary artery disease. The well-established single photon emission computed tomography (SPECT) as a myocardial imaging technique made an important progress with the recent improvement of high-speed volume acquisition, using dedicated semi-conductor gamma camera. These cameras bring significant improvement to the image quality and the image acquisition time, which is now seven times lower. New type of artefacts is expected because of the geometry of detection, thus studies are still needed to assess the exact performance of this revolutionary technology. (authors)

    The goal of this prospective study is establishing the evolution and long term prognostication in chronic ethylic patients afflicted with severe cardiac insufficiency (CI), presenting a dilated cardiomyopathy (DCM). Forty patients (average age 44.8 {+-} 9.2 years) are consecutively included according to the following criteria: CI (stage IV), DCM without definite etiology, chronic alcoholism during more than 10 years and superior to 80 g alcohol/day. The telediastolic diameter (TDD) of left ventricle viewed by echo-cardiogram is increased up to 68.4 {+-} 3.6 mm with a fraction of shortening (FS) of 14.2 {+-} 3.7%. The isotopic ejection fraction (EF) is lowered down to 21.6 {+-} 5.9%. All the patients received a conventional treatment of CI while the abstinence was hardly urged. Three patients recurred and subsequently refused the follow-up. By the third month, in absence of any amelioration, a patient benefited by a cardiac transplant and another patient deceased after myocardial biopsy. Nine patients benefited by a complete follow-up of 36 months. After the third month the functional amelioration is notable and confirmed by different parameters: TDD of 64.3 {+-} 3.6 (p < 0.02), FS of 18.8 {+-} 7.2% (NS) and EF of 31.3 {+-} 11.1% (p < 0.03). The amelioration of different criteria is significant by the 6. month and than stabilizes itself up to 3 years as showed by the EF evolution curves. In conclusion, the prognostication of these patients with severe CI is favorable. The functional amelioration is precocious and confirmed by the different ventricular parameters studied. The medical treatment associated with a complete and definitive abstinence is the key of success

    Congestive heart failure is often associated with an impairment of the sympathetic nervous system, i.e., global hyperactivity and regional impairment of the adrenergic system. Cardiac {sup 123}I-MIBG scintigraphy is a radionuclide technique which can explore the presynaptic adrenergic function. Myocardial MIBG fixation is decreased in congestive heart failure, reflecting a reduction of norepinephrine uptake by the myocardial presynaptic nerve endings. The impairment of presynaptic function occurs early in the disease and is actually involved in the pathogenesis of cardiac failure. Cardiac MIBG scintigraphy is a useful tool to explore the myocardial adrenergic stores in patients with congestive heart failure. It could be proposed in patients with severe ventricular dysfunction in order to assist physicians in setting-up the timing of heart transplantation. (authors). 52 refs.

    La cardiomyopathie hypertrophique néonatale est une entité rare, hétérogène regroupant plusieurs formes cliniques et donc de diagnostic étiologique difficile. Nous rapportons l'observation d'un nouveau né issu d'une grossesse gémellaire, ayant présenté à la naissance un tableau d'insuffisance cardiaque, l’échocardiographie avait conclut à une cardiomyopathie hypertrophique obstructive. Le bilan étiologique était négatif notamment une mère non diabétique. L’évolution était favorable avec régression de l'hypertrophie 2 semaines après la naissance. L’étiologie finalement suggérée était une cardiomyopathie secondaire à l'injection anténatale de corticoïdes dans le but d'accélérer la maturation pulmonaire. L’établissement par les sociétés savantes d'un consensus de bilan étiologique minimal standard selon une chronologie bien déterminée serait d'un grand apport dans la prise en charge de cette anomalie.

    The contribution of the new fuels to a greener environment is important and immediate. Thanks to clean novel technologies and to commercial plant projects in development, companies like Enerkem contribute to satisfy increasing global demand for clean energy. They stimulate local economies by creating jobs in an industry that offers real growth potential. Green fuels will gradually allow us to let go of non sustainable energy sources like oil to adopt a way of life based on sustainable development. They will also allow a shift towards a green economy.

    Full Text Available Krótki wywiad Witolda Wachowskiego z Johnem Zornem zawiera wiele cennych spostrzeżeń związanych z estetyką tego kompozytora. Rzekoma niechęć Zorna do publiczności, jego wiara w kreatywny instynkt „artysty” oraz jego przekonanie o transcendentalnej naturze dzieł muzycznych (które są bramą do świata „prawdy” i „piękna” niczym refren powtarzają się w wielu wywiadach z muzykiem. Zorn w krótkim wywiadzie z Wachowskim podkreśla właśnie te przekonania, dlatego możemy przyjąć, że stanowią one fundament jego muzycznej i artystycznej estetyki. Dla każdego, kto posiadł choćby podstawową wiedzę o zachodniej tradycji estetycznej, jest jasne, że te same cechy i stanowiska estetyczne charakteryzują muzyczne instytucje wspólne dla zachodniej tradycji artystycznej, a w szczególności „romantyczny” ideał muzyki i kompozytora rozwinięty w XIX wieku. Filozofowie (głównie Hegel i Kant razem z krytykami muzycznymi i kompozytorami (Schiller, Hoffmann, Schlegel, Schuman, Hanslick przyczynili się do stworzenia romantycznej estetyki muzycznej w XIX wieku, akcentującej rolę artysty („geniusza” lub „boga”, który tworzy „dzieła” odsłaniające – poprzez czysto muzyczne związki istniejące niezależnie od wrażliwości słuchacza – ukryte światy prawdy i piękna, światy odległe od trosk życia codziennego. Zważywszy na bliskie związki Zorna z estetykami/filozofami XIX-wiecznymi, można powiedzieć, że wyznaje on „romantyczny” pogląd na muzykę i sztukę.

    Several goals were achieved during this period of 9 months, both in the experimental laboratory and in patients with acute myocardial infarction. (1) A study of the effects of aprotinin administration on myocardial ischemic injury, subsequent necrosis and collateral blood flow following acute coronary artery occlusion was carried out to completion. (2) A study of the effect of cobra venom factor on myocardial necrosis was completed and the factors responsible for its action were examined. (3) A comparison was made of the effects of nitroglycerin and nitroprusside on ischemic injury and regional myocardial blood flow in patients with acute myocardial infarction and in dogs with coronary occlusions. (4) A method of direct measurement of infarct size in the rat was developed. It consists of occlusion of the main left coronary artery and the histologic quantification of the infarct at 48 hours and 3 weeks later by serial histologic sections or alternatively by measuring total left ventricular myocardial creative phosphokinase activity. (5) New electrocardiographic methods have been developed in order to evaluate atraumatically the extent of myocardial infarction in patients. (6) Intravenous injection of (113)mIn-ENTMP and (99m)TcENTMP in dogs following coronary artery occlusion permitted a sequential double labeling of the damaged myocardium. (7) Since hyaluronidase is a very effective drug in reducing myocardial damage both in the experimental animal and in patients with acute myocardial infarction, a study was carried out to ascertain its effects on collateral flow.

    The radiological investigation of persistent or recurrent sciatica after lumbar diskectomy essentially consists of demonstrating recurrent disk herniation. Comparison between plain and contrast enhanced CT or MR examinations at the level of the diskectomy is the main step of the radiological survey. The meanings of the various radiological findings are discussed. Other lesions that may induce persistent sciatica after lumbar diskectomy include degenerative narrowing of the lateral recess, spinal instability, stress fracture of the remaining neural arch, pseudo-meningomyelocele after laminectomy.

  17. Analysis of cost outliers within APR-DRGs in a Belgian general hospital: two complementary approaches.

    2006-03-01

    The objective of this study was to find factors that could explain high and low resource use outliers, by associating an explanatory analysis with a statistical analysis. High resource use outliers were selected according to the following rule: 75th percentile + 1.5* inter-quartile range. Low resource use outliers were selected according to: 25th percentile - 1.5* inter-quartile range. The statistical approach was based on a multivariate analysis using logistic regression. A decision tree approach using predictors from this analysis (intensive care unit (ICU) stay, high severity of illness and social factors associated with longer length of stay) was also tested as a more intuitive tool for use by hospitals in focussing review efforts on "not explained" cost outliers. High resource use outliers accounted for 6.31% of the hospital stays versus 1.07% for low resource use outliers. The probability of a patient being a high resource use outlier was higher with an increase in the length of stay (odds ratios (OR) = 1.08), when the patient was treated in an intensive care unit (OR = 3.02), with a major or extreme severity of illness (OR=1.46), and with the presence of social factors (OR = 1.44). The probability of being a low outlier is lower for older patients (OR = 0.98). The probability of being a low outlier is also lower without readmission within the year (OR = 0.55). The more intuitive decision tree method identified 92.26% of the cases identified through residuals of the regression model. One quarter of the high cost outliers were flagged for additional review ("not justified" on the basis of the model), with nearly three-quarters "justified" by clinical and social factors. The analysis of cost outliers can meet different aims (financing of justifiable outliers, improvement of the care process for the outliers not justifiable on medical or social grounds). The two methods are complementary, by proposing a statistical and a didactic approach to achieve the goal of high quality care using fewer resources.

    Purpose A retrospective analysis of risk factors for late neurological toxicity after nasopharyngeal carcinoma radiotherapy. Patients and methods Between 1993 and 2004, 239 patients with non metastatic nasopharyngeal carcinoma were treated by radiotherapy associated or not to chemotherapy. Radiotherapy was delivered with two modalities: hyperfractionated for 82 patients and conventional fractionation for 157 patients. We evaluated the impact of tumour stage, age, gender, radiotherapy schedule and chemotherapy on neurological toxicity. Results After a mean follow-up of 107 months (35-176 months), 21 patients (8.8%) developed neurological complications, such as temporal necrosis in nine cases, brain stem necrosis in five cases, optics nerve atrophy in two cases and myelitis in one case. Five- and ten-year free of toxicity survival was 95 and 84% respectively. Young patients had greater risk of temporal necrosis, and hyperfractionated radiotherapy was associated with a significantly higher risk of neurological complications (14.6% vs 5.7%, p = 0.02). On multivariate analysis, hyperfractionation and age were insignificant. Conclusion Late neurological toxicity after radiotherapy for nasopharyngeal carcinoma was rare. Younger age and hyperfractionation were considered as risk factors of neurological toxicity in our study

    Les méningites sont des complications rares mais graves des anesthésies péridurales et des rachianesthésies. Les méningites bactériennes sont essentiellement dues à des cocci à Gram positif, ce qui sous-entend une contamination exogène pouvant être le témoin d'une faute d'asepsie. L’évolution est le plus souvent favorable sous traitement, mais au prix d'un accroissement des dépenses de santé et parfois d'importantes séquelles neurologiques. Nous présentons un cas de méningite bactérienne au décours d'une rachianesthésie effectué pour césarienne. PMID:27642477

    Sexual dysfunctions are a quality of life main concern following prostate cancer treatment. After both radiotherapy and brachytherapy, sexual function declines progressively, the onset of occurrence of erectile dysfunction being 12-18 months after both treatments. The pathophysiological pathways by which radiotherapy and brachytherapy cause erectile dysfunction are multi-factorial, as patient co-morbidities, arterial damage, exposure of neurovascular bundle to high levels of radiation, and radiation dose received by the corpora cavernosa at the crurae of the penis may be important in the aetiology of erectile dysfunction. Diagnosis and treatment of postradiation sexual dysfunctions must integrate pre-therapeutic evaluation and information to provide to the patient and his partner a multidisciplinary sexual medicine management.

    In recent years, due to speedy rise of international oil prices, orders of nuclear power plant construction have been in progress by many countries to solve the stable supply of power. Our country has continued to perform nuclear power construction. As only a few developed countries like Japan and European countries have its own nuclear power construction technology, competition among them is keen. Our country has awarded the contract of UAE nuclear power plants based on the accumulated nuclear power plant construction technologies so far. In this regard, KEPCO has recognized the needs of information management system to manage nuclear power information and proceeded the implementation of nuclear power information management system for export-model

  1. The sensitivity analysis for APR1400 nodalization under Large Break LOCA condition based on mars code

    Full Text Available The phenomena of loss of coolant accident have been investigated for long time and the result of experiment shows that the flow condition in the downcomer during the end-of-blowdown were highly multi-dimensional at full-scale. However, the downcomer nodalization of input deck for large break loss of coolant accident used in advanced power reactor 1400 analyses are made up with 1-D model and improperly designed to describe realistic coolant phenomena during loss of coolant accident analysis. In this paper, the authors modified the nodalization of MARS code LBLOCA input deck and performed LBLOCA analysis with new input deck. From original LBLOCA input deck file, the nodalization of downcomer and junction connections with 4 cold legs and direct vessel injection lines are modified for reflecting the realistic cross-flow effect and real downcomer structure. The analysis results show that the peak cladding temperature of new input deck decreases more rapidly than previous result and that the drop of peak cladding temperature was advanced by application of momentum flux term in cross-flow. Additionally, the authors developed a new input deck with multi-dimensional downcomer model and ran MARS code with multi-dimensional input deck as well. By using the modified input deck, the Emergency core cooling system by-pass flow phenomena is better characterized and found to be consistent with both experimental report and regulatory guide.

    The author notices that the known reserves of uranium should be sufficient to supply existing reactors and new water reactors for the next decades, and that fuel recycling and reactor improvements as well as regenerator reactors should limit the pressure on these reserves. This means that nuclear physics and economics are in close relationship, that which can lead to the definition of several scenarios. They outline the importance of exploration capacities and of the evolution of the world nuclear reactor stock on a long term (by 2050) for the assessment to future uranium needs

    several studies are presently undertaken in the Walloon Region so as to assess the long term environmental impact caused by the shutting down of coal mines and their pumping operations. In many locations, new problems are encountered, such as sudden underground water appearance at hill slopes, coal heaps instability or flooding of underground cellars. Slope instability increase risks. The main goals of the presented studies are to suppress or at least to limit those risks and inconveniences and propose solutions to be implemented in the framework of the existing dewatering facilities built by the Walloon Region and local authorities in mines induced subsidence areas.

    Until now, nuclear power has been only used for the base load power operation. However, current nuclear power plants are recognized as the most reasonable energy source. As a result, the proportion of nuclear power has being grown increasingly. Therefore, load following operation of a nuclear power plant should be an essential option. Most of the existing nuclear power plants perform reactor operation by varying the boron concentration in the coolant. But it is hard to respond quickly to demands for the power changes. In case of using the control rods, reactivity control is easy, but axial power distribution control is very hard because it has very complex and nonlinear dynamic characteristics. In this study, we have introduced a Model Predictive Control (MPC) method to control the average coolant temperature and Axial Shape Index (ASI) automatically at the same time, and we have improved the performance of controller by applying the Genetic Algorithm (GA) to optimize the control rod movement.

    The flow rate is actually measured using UFM (Ultrasonic Flow Meter) in the hot leg, but it is important to ensure the flow meter's performance with a highest degree of confidence. To reduce the uncertainty of the flow meter, the adequate correction factor for the thermal and hydraulic characteristics of the fluid flow should be entered as an input data into the flow meter. The thermal stratification effect on the velocity measurement was investigated to reduce the associated uncertainty by Chang. From the hydraulic point of view, the velocity profiles for the inner diameter is also important to compensate for the distortion of the measurement, but there are not any reported literature. Therefore, the present study will elaborated on the hot leg velocity measurement and the results will be provide for the design data. Under the 4-pump balanced flow condition, the velocity profile was measured along the central angle of the hot leg by using the ACOP test facility.

    The report provides estimates of capital and operating costs for industrial boilers. Costs are related to the type of fuel fired, firing design and rated capacity. Both package and field-erected boilers are evaluated. Fuels considered include coal, residual oil, distillate oil and natural gas. Firing designs for coal include underfeed-stoker, spreader-stoker and pulverized. Rated capacities range from 15(10 to the 6th)Btu/hr for oil and gas to 700(10 to the 6th)Btu/hr for coal. Costs are developed on a study estimate basis. Individual boiler cost estimates were plotted and cost equations developed for total equipment, installation (direct and indirect) and operating costs (variable and fixed).

    The Fukushima Daiichi nuclear power plant accident showed the vulnerability of coping strategy to beyond design natural disaster such as beyond design earthquake and tsunami. In Korea, the government and industry performed comprehensive safety inspection on all domestic nuclear power plants against beyond design basis external events and fifty action items have been issued. In addition to post- Fukushima action items, the stress tests for all domestic nuclear power plants are on the way to enhance the safety of domestic nuclear power plants through finding the vulnerabilities in intentional stress conditions initiated by beyond design natural disaster. Recently, the stress tests for WOLSONG Unit 1 and KORI Unit 1 have been performed and their assessment results have been reviewed by Korean regulatory body. The assessment of the coping capability of KORI Unit 1 has been performed under simultaneous the extended loss of AC power and loss of ultimate heat sink initiated by beyond design natural disaster. It is concluded that KORI Unit 1 has the capability, in the event of loss of safety functions by beyond design natural disaster, to sufficiently cool down the reactor core without fuel damage, to keep pressure boundaries of the reactor coolant system in transient condition and to control containment and temperature to maintain the integrity of the containment buildings. The several additional items for safety improvement has been drawn to enhance the coping capability for loss of safety functions under beyond design natural disaster in addition to post Fukushima action items.

    Recently newly-developed nuclear reactors with increased safety and enhanced performance by developed countries in the nuclear area are competing in the global nuclear market. Several reactors, for example AP600 and AP1000 by Westinghouse Electric Co. in USA, EPR by Areva in Europe, APWR by Mitsubishi Heavy Industry in Japan in the pressurized power reactor, are competing to preoccupy the nuclear market during Nuclear Renaissance. Dedicated control element drive mechanism with enhanced performance and increased safety are developed for these new reactors. And load follow capability is required, and it is estimated that load follow requirement make design requirement of a control element drive mechanism harsh. It is necessary to review the current technical state of a control element drive mechanism. This work is aimed to review the design characteristics of a past and current control element drive mechanism for a nuclear reactor and to check the direction and goal of CEDM design development recently.

    This article uses the Iraq war major event to analyze the approach used by the US to fight against proliferation. It questions the decision and analysis process which has led to the US-British intervention and analyzes the consequences of the war on the proliferation of other countries and on the expected perspectives. Finally, the future of proliferation itself is questioned: do we have to fear more threat or is the virtuous circle of non-proliferation well started? (J.S.)

    Although radical prostatectomy is an effective treatment for clinically localized prostate cancer, it fails in up to 20 to 40% of the cases. Local failure represents one of the possible patterns of relapse and is announced by detectable serum P.S.A. levels. Patients at high risk for local relapse have extra prostatic disease, positive surgical margins or seminal vesicles infiltration at pathology. Three recently published phase III randomized clinical trials have clearly shown that, for these patients, immediate adjuvant irradiation reduces the risk of progression. For patients undergoing postoperative irradiation the standardisation of the target volume definition and delineation is required because no general consensus exists on prostate bed definition. The Genito-Urinary Working Party of the Radiation Oncology Group of the European Organization for the Research and treatment of cancer (R.O.G. O.R.T.C.) has developed a set of Guidelines to assist radiotherapists in the contouring of target volumes for postoperative irradiation: a consensus has been reached on a set of recommendations that are proposed to the radiation oncologist community. Emphasis has been put on the optimal cooperation between the surgeon, the pathologist and the radiotherapist in the frame of a multidisciplinary approach. Data on the presence and on the localization of extra prostatic extension and on positive surgical margins must be used. Placement of metallic clips in the tumor bed is of great help in localizing fixed anatomical sites as the anastomosis. The goal of such a document is to reduce inter-observer variability in target delineation in the framework of future clinical trials. (author)

    Summary Il s'agit d'une étude faisant ressortir les aspects épidémiologiques, cliniques et thérapeutiques des séquelles de brûlures du membre inférieur chez l'enfant, à propos de 42 cas colligés au service de chirurgie infantile de l'Hôpital Aristide Le Dantec (Sénégal). L'âge moyen retrouvé est de 5 ans et 3 mois, et le sex-ratio garçons/filles de 1,8/1. La brûlure thermique est causée par une flamme dans 33% des cas, par un liquide chaud dans 21% des cas, et par des braises dans 21% des cas. Les cicatrices rétractiles intéressent le genou et le creux poplité dans 47% des cas et le pied dans 45% des cas. Elles sont bilatérales dans 21% des cas, et concernent une autre localisation associée dans 21% des cas. Quant aux brides, 21% ont bénéficié d'une chirurgie, avec un délai moyen de 3 ans et 2 mois après la brûlure. Cette procédure chirurgicale consiste en une plastie en Z dans 91% des cas, à laquelle est associée une greffe de peau dans 54% des cas. Une rééducation fonctionnelle est pratiquée chez 54% des opérés. Parallèlement aux données de la littérature, nos résultats montrent que l'optimisation de la prise en charge passe par une meilleure prévention des accidents domestiques et une bonne codification thérapeutique.

    Le cancer du sein est actuellement le cancer le plus fréquent chez la femme, et pose un véritable problème diagnostique et thérapeutique. Le dépistage des lésions à un stade de plus en plus précoce, a permis une extension des indications du traitement conservateur radiochirurgical, qui était initialement limitées aux tumeurs de moins de 3 cm, unifocales, non inflammatoires. Par ailleurs, l'utilisation de traitements préopératoires permet d’étendre les indications du traitement conservateur à des tumeurs plus volumineuses. Parallèlement à cette extension des indications de conservation mammaire, on a observé le développement de nouvelles approches thérapeutiques notamment la chirurgie oncoplastique, technique du ganglion sentinelle et chirurgie stéréotaxique, dont les résultats initiaux sont très encouragent. A travers cette étude réalisée dans le service de gynécologie et obstétrique II du CHU HASSAN II de FES au MAROC, après l'analyse rétrospective de 16 patientes traitées par traitement conservateur et oncoplastie, nous avons voulus montrer notre aptitude a réalisé ses techniques chirurgicales et a bien prendre en charge ces patientes, mais aussi évaluer ces techniques en termes de résultat carcinologique et de résultat esthétique, aussi en terme de survie globale, survie sans métastase et en termes de récidive locale entre les plasties mammaires et les traitements usuels: mastectomie et traitement conservateur classique.

    Les cardiopathies de l'enfant déterminent en Afrique un problème de santé publique difficile à prendre en charge, de part la densité de la population jeune, le faible niveau socioéconomique et l'insuffisance de plateaux techniques adaptés. Les auteurs rapportent les aspects échocardiographiques et thérapeutiques des cardiopathies de l'enfant dans le département de pédiatrie du CHUSS de Bobo-Dioulasso. Il s'agissait d'une étude transversale descriptive concernant la période de janvier 2013 à décembre 2014 (24 mois). Elle a consisté en une revue documentaire des comptes rendus d'échocardiographies réalisées chez les enfants de moins de 15 ans dans le laboratoire d'échocardiographie du CHUSS et de leurs dossiers de suivi thérapeutique. Durant la période d'étude, 184 examens écho-cardiographiques avaient été réalisés et permis la mise en évidence de 93 cas de cardiopathies de l'enfant, soit 50,50% des cas. Parmi eux, on distinguait 71% (66/93) de cardiopathies congénitales et 29% (27/93) de cardiopathies acquises. Les cardiopathies congénitales les plus fréquentes étaient : la CIV (27,2%), CIA (10,6%), CAV (7,5%), T4F (9,1%), TAC (6%), formes associées (15%). Les cardiopathies acquises étaient dominées par les valvulopathies rhumatismales (48%), la cardiomyopathie dilatée hypokinétique (33,3%) et la tamponnade péricardite (18,5%). L'indication chirurgicale était posée dans 53,7% (50/93) des cas dont 86% (43/50) de cardiopathies congénitales et 14% (7/50) de cardiopathies acquises. 21% (9/43) des cardiopathies congénitales ont bénéficié d'une chirurgie cardiaque. Aucune cardiopathie acquise d'indication thérapeutique chirurgicale n'avait été opérée. Les cardiopathies de l'enfant sont fréquentes à Bobo-Dioulasso. La conception de stratégies multidisciplinaires associées à une optimisation des moyens devraient améliorer la prise en charge de ces cardiopathies. PMID:28250886

    Full Text Available [english] We report an unusual case of an 18-year-old female semiprofessional boxer presenting with finger and nail deformity of the right hand after symbrachydactyly separation in childhood in whom we performed exoskeletal prosthesis for aesthetic reasons.Because of the complexity of finger deformities and limitation of surgical interventions exoskeletal prosthesis were performed.To evaluate a potential improvement of finger dexterity we performed the Nine Hole Peg Test. This is a simple and commercially available upper extremity functional assessment instrument. To evaluate the quality of life we performed the Short Form 36-Item Health Survey (, a questionnaire designed to examine a person’s perceived health status.The prosthesis provided an excellent aesthetic result and improvement of self-confidence. No functional improvement could be obtained in this special case as it is described in patients with finger amputations.Especially in women malformations of the hand and fingers are often associated with psychological impairments and social isolation. In this case and after surgery in childhood exoskeletal prostheses provide a useful option to improve the aesthetical outcome as well as quality of life.[german] Wir berichten über eine 18-jährige semiprofessionelle Boxerin mit Nagel- und Fingerdeformitäten der rechten Hand nach operativer Korrektur einer Symbrachydaktylie in der Kindheit. Zur Verbesserung des Erscheinungsbildes der rechten Hand erfolgte die Anpassung von Fingerepithesen.Die Anpassung der Epithesen erfolgte in diesem Fall aufgrund der limitierten chirurgischen Behandlungsoptionen und diente in erster Linie zur Verbesserung der Ästhetik und Steigerung des Selbstwertgefühls. Zur objektiven Messung der Fingerfertigkeit setzten wir den Nine Hole Peg Test ein. Dieser Test ist ein einfaches und kommerziell erhältliches Instrument zur funktionellen Messung im Bereich der oberen Gliedmaßen.Zur Erfassung der gesundheitsbezogenen Lebensqualität wendeten wir den SF-36 (Short Form 36-Item Health Survey an. Dieser Test erfasst acht Dimensionen der subjektiven Gesundheit.Entgegen der Beschreibung bei Patienten nach Fingeramputation konnte in diesem speziellen Fall keine Verbesserung der Fingerfertigkeit erzielt werden. Es zeigte sich jedoch eine deutlliche Verbesserung im Hinblick auf die Lebensqualität der Patientin.Insbesondere Frauen sind durch fehlgebildete Hände und Finger infolge angeborener Fehlbildungen, aber auch nach Trauma häufig psychisch stark belastet, was nicht selten zu sozialer Isolation und Beeinträchtigung des Selbstwertgefühls führt.Hier können Epithesen dazu beitragen, das ästhetische Erscheinungsbild der Hand deutlich zu verbessern und die Lebensqualität der Patienten zu steigern.

    The treatment of advanced, drug resistant congestive heart failure gains in importance in the field of cardiac surgery. Cardiac imaging for preoperative assessment and follow-up focuses on the determination of ventricular volumes and function as well as on the detection of postoperative complications. Computed tomography (CT) is highly accurate irrespective of the individual patient's anatomic situation, has a low examiner dependence and short examination time, does not require an arterial vascular access and can be performed in patients with metal implants. CT is the modality of choice in the follow-up of heart transplants to detect extracardiac and cardiac complications including coronary calcifications as an early sign of transplant vasculopathy. In addition, CT visualizes the elements of mechanical assist devices and can identify their possible local cardiac and mediastinal complications CT can detect fibrolipomatous involution of the mobilized muscle flap in dynamic cardiomyoplasty and can depict fibrous reactions along the epicardial mesh implant in passive cardiac containment. Further indications include assessment of typical local postoperative complications, such as intrathoracic infection and mediastinal bleeding, intracardiac thrombus formation or pericardial effusion. CT is routinely used for evaluating bypass patency but is limited in assessing associated valve defects since it does not visualize flow. (orig.)

    The French ministry of economy finances and industry has assigned the mission of evaluating the after-mine management system to the general inspection of finances and the general council of mines. The after-mine management system encompasses all procedures of coal, iron and potash mines closing down, land reclamation and environmental remedial action and site rehabilitation. This document makes first a status of the problems generated by the stoppage of mining activities: technical aspects, costs, institutional, organisational and juridical aspects, conservation of competences, international benchmarking elements and good practices implemented in foreign countries. Then, in a second part, this report presents the recommendations of the after-mine mission about the mastery of after-mine costs in agreement with the respect of the technical and social goals, with the development of the after-mine institutional system with the scheduled disappearance of Charbonnages de France and Mines de Potasses d'Alsace companies, and with the conservation of competences in the framework of the post-mine operational structure proposed by the mission.

    Full Text Available The liberalization of the cotton sector in Ivory Coast after fifteen years: spatial and organizational marks. The liberalization of the cotton sector in Ivory Coast is inspired by industrialized countries. Its approaches are supported by the Breton Woods institutions and the French Cooperation. The aim of this study is to review spatial and organizational reforms in the cotton basin of Ivory Coast. The results of this research revealed that liberalization is the cause of the restructuring of the cotton area. On the other hand, it has resulted an organizational dynamic based on the activity of the cotton companies and producers. In addition, the areas defined by the liberalization are not respected by cotton agencies. This non-compliance is manifested by the incursion of cotton companies in areas outside their initial block. In this logic of incursion, the producers of public society (CIDT produce significantly more than those supervised by private cotton companies. This observation raises a debate regarding the continued liberalization of the cotton sector in Ivory Coast.

    In the study, an Augmented Reality procedure guidance support system concept was designed and used as a tool for the measurement of mental workload and Situational awareness of an SRO (Senior Reactor Operator). The EOP was chosen as the scenario for testing because it is the one of the critical plant conditions that requires human intervention and it represents (one of the more) conservative approaches to the test scenarios that are possible. The system is expected to realize an improvement in the level of Situational Awareness and mental workload which have been demonstrated by previous studies to be directly linked with the system response to an emergency situation in the MCR. The planning and design of the project adhered to a Systems Engineering approach in order to provide an optimized framework for ensuring the successful implementation of the system design. Previous study and research into this topic has emphasized the importance of situational awareness in determining the human factor performance issues in the nuclear power plant Control Room operations. This paper broadly defined a technique that successfully used the operator’s mental workload (using NASATLX) and Situational Awareness (using SART) as quantifying measures to evaluate the performance of specific ESF-CCS functions based on human factors. These results show that an improvement of the SA/workload could lead to an improvement of the level of certainty that the emergency situation can be brought under control. It is expected that future development work in this area will yield an actualized Augmented Reality system that could incorporate MCR team control and possibly be implemented in the system validation of other I and C systems.

  10. Experiments and computational modeling of pulverized-coal ignition. Semiannual report, Apr 1, 1998--Sep 30, 1998

    Energy Technology Data Exchange (ETDEWEB)

    1998-10-31

    Under typical conditions of pulverized-coal combustion, which is characterized by fine particles heated at very high rates, there is currently a lack of certainty regarding the ignition mechanism of bituminous and lower rank coals. It is unclear whether ignition occurs first at the particle-oxygen interface (heterogeneous ignition) or if it occurs in the gas phase due to ignition of the devolatilization products (homogeneous ignition). Furthermore, there have been no previous studies aimed at determining the dependence of the ignition mechanism on variations in experimental conditions, such as particle size, oxygen concentration, and heating rate. Finally, there is a need to improve current mathematical models of ignition to realistically and accurately depict the particle-to-particle variations that exist within a coal sample. Such a model is needed to extract useful reaction parameters from ignition studies, and to interpret ignition data in a more meaningful way. The authors propose to examine fundamental aspects of coal ignition through (1) experiments to determine the ignition mechanism of various coals by direct observation, and (2) modeling of the ignition process to derive rate constants and to provide a more insightful interpretation of data from ignition experiments. They propose to use a novel laser-based ignition experiment to achieve their objectives. The heating source will be a pulsed, carbon dioxide laser in which both the pulse energy and pulse duration are independently variable, allowing for a wide range of heating rates and particle temperatures--both of which are decoupled from each other and from the particle size. This level of control over the experimental conditions is truly novel in ignition and combustion experiments. Laser-ignition experiments also offer the distinct advantage of easy optical access to the particles because of the absence of a furnace or radiating walls, and thus permit direct observation and particle temperature measurement. The ignition mechanism of different coals under various experimental conditions can therefore be easily determined by direct observation with high-speed photography. The ignition rate-constants, when the ignition occurs heterogeneously, and the particle heating rates will both be determined from analyses based on direct, particle-temperature measurements using two-color pyrometry.

    The goal of localized prostate cancer radiotherapy is to cure patients. The decision-making must integrate the survival but also the quality of life of patients. Some French validated self-reported questionnaires are available to evaluate quality of life. Whatever the treatments (radical prostatectomy, brachytherapy, external beam radiation, with or without hormono-therapy), even if patients report more sequelae, their long-term quality of life is similar to that of the general population, except for patients treated with hormono-therapy who complain more decline of physical quality of life. In comparison with prostatectomy, patients treated with external beam radiation report less long-lasting urinary symptoms, but more bowel side effects, with no difference in global quality of life. Sexual disorders are initially less important with external beam radiation but increase over time. Brachytherapy shows no sexual function preservation benefit relative to radiation and may be less favourable with more urinary sequelae. The association of hormono-therapy and external beam radiation decreases the quality of life of the patients, with a negative impact on vitality, sexuality and increase urinary disorders. Intensity-modulated radiotherapy (IMRT) seems to better preserve the long-term digestive quality of life in comparison with conformal radiation therapy. Post-prostatectomy could induce more digestive toxicity, such as rectal irritation. The adjunction of hormono-therapy to radiation, the previous medical history of abdominal surgery, the field of radiation and the acute reactions to radiation are the main predictive factors to late toxicity and should be considered in the choice of initial treatment and for the follow-up.

    Full Text Available Les digues de polders littoraux comprennent plusieurs catégories : digues de mer, digues de rebras, digues dormantes et digues ruinées. Dans le marais Poitevin, la tempête Xynthia, pendant laquelle la mer a atteint un niveau exceptionnel, a submergé l'ensemble du réseau des digues. Elle a permis de prendre conscience de l'état du réseau des digues et de l'absence d'une ligne continue de digues dormantes d'un niveau suffisant pour limiter l'extension de l'inondation.Des solutions adoptées ailleurs en Europe, comme la transformation des polders en polders d'été ou la dépoldérisation n'ont pas été envisagées. La réparation à l'identique, avec un renforcement a été adoptée. D'une façon plus générale, des indices sont proposés pour aider à la gestion des polders littoraux. Ces indices doivent tenir compte de la valeur écosystémique des schorres dont la biodiversité et la productivité sont exceptionnelles. La nécessité de quantifier les enjeux – ce qui est certes difficile – apparaît d'autant plus nécessaire que la montée du niveau de la mer risque de contraindre une politique de maintien rigide du trait de côte à des investissements disproportionnés à long terme.Polder dikes coasts include several categories: sea dikes, sleeper dikes and devastated levees. In Marais Poitevin, during the storm Xynthia, the entire network of dikes has been flooded due to the exceptional level of the sea at that time. This situation has raised awareness of the status network of the current network of levees and of the lack of a continuous line of sleeper levees at a sufficient level to limit the extent of the flooding.Solutions adopted elsewhere in Europe, such as processing of the polders in summer polders or depolderization have not been considered. The decision has been taken to repair at the same and to reinforce the previous defences. In a more general way, the elaboration of indexes has been done to improve the management of coastal polders. These indexes should reflect the ecosystem value of salt marshes whose biodiversity and productivity are outstanding. Although it may be difficult, the necessity to assess the different issues is necessary indeed because the rising of the sea level may force to maintain rigid coastline at a disproportionate investment in the long term.

    The hematopoietic compartment is one of the most severely damaged after chemotherapy, radiotherapy or accidental irradiations. Whatever its origin, the resulting damage to the bone marrow remains difficult to evaluate. Thus, it would be of great interest to get a biological indicator of residual hematopoiesis in order to adapt the treatment to each clinical situation. Recent results indicated that the plasma Flt3 ligand concentration was increased in patients suffering from either acquired or induced aplasia, suggesting that Flt3 ligand might be useful as a biological indicator of bone marrow status. We thus followed in a mouse model as well as in several clinical situations the variations in plasma Flt3 ligand concentration, after either homogeneous or heterogeneous irradiations. These variations were correlated to the number of hematopoietic progenitors and to other parameters such as duration and depth of pancytopenia. The results indicated that the concentration of Flt3 ligand in the blood reflects the bone marrow status, and that the follow-up of plasma Flt3 ligand concentration could give predictive information about the bone marrow function and the duration and severity of pancytopenia and thrombocytopenia. Nevertheless, the clinical use of Flt3 ligand as a biological indicator of bone marrow damage require the knowledge of the mechanisms regulating the variations in plasma Flt3 ligand concentration. We thus developed a study in the mouse model. The results indicated that the variations in plasma Flt3 ligand variations were not solely due to a balance between its production by lymphoid cells and its consumption by hematopoietic cells. Moreover, we showed that T lymphocytes are not the main regulator of plasma Flt3 ligand concentration as previously suggested, and that other cell types, possibly including bone marrow stromal cells, might be strongly implicated. These results also suggest that the Flt3 ligand is a main systemic regulator of hematopoiesis, especially during induced bone marrow aplasia. (author)

    This report, which covers battery manufacturing operations, is one of a series of several studies which examine land-destined wastes from selected industries. The battery industry is divided into two groups by the Bureau of Census: Standard Industrial Classification (SIC) 3691 Storage Batteries (such as lead--acid automobile batteries) and SIC 3692 Primary Batteries (such as carbon--zinc flashlight batteries). The battery industry was studied because heavy metals such as mercury, cadmium, zinc, and lead are used in some of its manufacturing processes. These metals can be toxic in certain concentrations and forms. The potentially hazardous wastes destined for land disposal from the battery industry consist of industrial processing wastes, reject cells, and sludges from water pollution control devices. The amount of sludges destined for land disposal is expected to experience a large short term increase as water effluent guidelines are implemented. The impact of water effluent guidelines on land disposal of wastes is the largest single factor in determining future trends for this industry.

    2001-02-01

    The author presents how the mass media have dealt with the fourteenth anniversary of the Chernobyl accident. Nowadays Chernobyl epitomizes the hazards of nuclear energy. Public opinion has become extremely sensitive to topics concerning human health. This sensitivity is due to previous important affairs such as the scandal of the tainted blood, the mad cow disease or the syndrome of the Balkan war. Most media have broadened the debate to the sanitary impact of nuclear activities. The hyper-mediatization of the legal case of a man prosecuting the French state for no having taken adequate measures when the radioactive cloud spread over France, has given the feeling that French authorities have always wrongly minimized the consequences of the accident.

    2016-09-01

    The effect of DNA topology simplification by type II topoisomerase enzymes was discovered experimentally by Rybenkov et al. [1] 20 years ago - which motivates me to borrow the title for this comment from Alexandre Dumas [2]. Ever since the original discovery, the effect keeps entertaining theorists - but the most surprising fact is that the original experiment was never repeated, let alone improved. I do not understand why it is so. In my opinion, there is an acute need of new experiments, not only repeating the original measurements, but also examining numerous other aspects of the phenomenon. In this sense, the review [3] by Vologodskii, one of the original discoverers, is both timely and important. In his review, Vologodskii concentrates on what I would call mechanical aspect of the problem - how bent are T- and G-segments, what kinds of juxtaposition are relevant, etc. The importance of these issues notwithstanding, I want to complement this approach, and to consider in greater detail the thermodynamics of the process. My main points are as follows: action of topo II enzyme violates detailed balance for DNA, leading to circular currents and dissipation (which is indeed quite a common occurrence in many living systems). These currents are potentially observable, and dissipation measurable, which should challenge experimenters. The main goal of this comment is to show how general phenomenological point of view allows to formulate theoretical prediction for the energy dissipation rate.

    Indirect radionuclide lymphoscintigraphy is a safe, non-invasive and physiological method for the assessment of the limb lymphatic system. Colloids as antimony or rhenium sulphide labeled with 99m technetium have been widely used for morphological studies. Quantitative studies involving a continuous count rate monitoring of the injection sites followed by a computer analysis of dynamic image sequences have been a new promising step for an objective measurement of the peripheral lymphatic function. The injection site is always bilateral on the first web space of either the hand or the foot using a small volume (<0.2 mL) of the radiocolloid. This method has been validated on 30 young healthy volunteers and normal values established from a group of 125 upper and 141 lower limbs (normal subjects). The normal results showed a slight but continuous decrease in lymphatic function depending on the age of the subject. In pathological situations, we observed dysfunction of the lymphatic system in pure lymphoedemas or so-called lympho-venous edemas as demonstrated on the 1,182 upper and 2,463 lower limbs tested. The radionuclide lymphoscintigraphy may be helpful in cases of unilateral swollen limbs demonstrating a lymphatic dysfunction on a clinically normal contralateral limb at the first stage of a distal edema which appears within a few weeks or days, in a transient edema phase when normal status and oedema alternate. The lymphoscintigraphy gives objective and reproducible parameters necessary to assess the lymphatic variation under therapy (decongestive physiotherapy, surgery, drugs) and may be useful in the selection of new lympho-tonic treatments. This method is only reflecting the lymphatic function and is unable to appreciate the total lymphatic flow of the limb. Its results only reflect what happens at the injection site and it may be necessary to add a second test using a proximal injection in order to assess the occurrence of lymph nodes not visualized by the general method.

    The report summarizes results of a test program to characterize fugitive emissions from the Kosovo coal gasification plant in Yugoslavia, a test program implemented by the EPA in response to a need for representative data on the potential environmental impacts of Lurgi coal gasification technology. Major objectives of the fugitive emissions assessment were to: (1) determine the frequency of leak occurrence, (2) measure leak rates from leak sources, (3) estimate total fugitive emissions from leakage, and (4) compare the results to other fugitive emission test data. Study results show similarities to results of fugitive emission testing in U.S. oil refineries and organic chemical plants.

    Full Text Available Semântica estrutural, o primeiro livro de Greimas, é de longa data, na semiótica, um « clássico », ou dito de outro modo um desses monumentos que se olha com respeito, mas geralmente de longe. No entanto, o seu interesse não se restringe ao aspecto histórico. Hoje ainda, a fecundidade da semiótica « greimasiana »,mas também a maioria das dificuldades que lhe são inerentes resultam de três opções fundamentais formuladas nesse livro : escolha em favor de uma teoria gerativa, baseamento da problemática da significação na gramativa da narratividade, papel essencial atribuído à percepção como fundamento da apreensão da significação. Explicitando os problemas que colocam essas escolhas e as perspectivas que elas abrem , o artigo acaba por situar umas em relação às outras as múltiplas tendências atuais da pesquisa, desde a semiótica « standard » até à semiótica do « sensível ».

    Full Text Available This paper presents the design, implementation and validation of the three-wheel holonomic motion system of a mobile robot designed to operate in homes. The holonomic motion system is described in terms of mechanical design and electronic control. The paper analyzes the kinematics of the motion system and validates the estimation of the trajectory comparing the displacement estimated with the internal odometry of the motors and the displacement estimated with a SLAM procedure based on LIDAR information. Results obtained in different experiments have shown a difference on less than 30 mm between the position estimated with the SLAM and odometry, and a difference in the angular orientation of the mobile robot lower than 5° in absolute displacements up to 1000 mm.

    The assessment of absorbed, equivalent and effective doses after internal exposure is based on activity measurement by in vivo counting or bioassay. A dose value is derived from this measurement by means of biokinetic and dosimetric models which describe the behaviour of radionuclides in the body of a reference man and the subsequent deposition of energy. To enforce regulatory dose limits, monitoring programs are designed. The doses can be estimated from the measurement data according to a standard procedure as proposed by the I.D.E.A.S. group. However, a significant uncertainty is associated with the dose estimate, due to the uncertainties of measurement, to the incomplete knowledge of the conditions of exposure and to the imperfect realism of the models. In addition to this uncertainty, the extrapolation to low dose of biological effects observed at higher dose, the chemical toxicity of radionuclides and the heterogeneous energy deposition make the estimation of the risk following an internal exposure very difficult. As a conclusion, it should be reminded that the effective dose is a tool for the management of radiological protection but not a quantitative indicator of the individual risk. (authors)

    Today, the argument in favour of nuclear energy is not an economical one nor linked to energy resources but is at the level of climatic change. Nuclear energy is seen as the only energy source without carbon dioxide emissions. A more detailed analysis of greenhouse gases on the life cycle shows that nuclear energy gives as greenhouse gases as big hydroelectric power plants or wind power plants, these emissions are more important than for biogas installations with cogeneration. The strategy of energy efficiency is certainly more competitive than the new reactors in other terms it is more efficiency to reduce the consumption than to increase the nuclear production. (N.C.)

    Introduction L'atteinte cardiovasculaire représente le facteur pronostique majeur de la drépanocytose. Méthodes C’était une étude transversale et descriptive dans le service de cardiologie du centre hospitalier et universitaire de Pointe-à-Pitre. Résultats Nous avons inclus 82 patients, 23 hommes (28%) et 59 femmes (72%), âgés en moyenne de 40,0±12 ans. On avait 39 patients porteurs d'hémoglobinose SS (49,4%) et 40 porteurs d'hémoglobinose SC (50,6%). Le taux d'hémoglobine de base était en moyenne de 9,8±1,8 g/dl et celui de l'hémoglobine fœtale était en moyenne de 5,5±5,3 g/dl. La fraction de raccourcissement était de 36±4,9% en moyenne, la FeVG moyenne était de 65±5,9%. On avait 68 patients avec un profil mitral normal (82,9%) et 14 patients avec un profil pseudo normal (17,1%). On avait une dilatation ventriculaire gauche chez 26 patients (31,7%), ventriculaire droite chez 14 patients (17.1%), une dilatation auriculaire gauche chez 36 patients (43.9%), auriculaire droite chez 11 patients (13.4%). On avait une hypertrophie ventriculaire gauche chez 13 patients soit 15.9%. L'hypertension artérielle pulmonaire a été retrouvée chez 43 patients soit 52,4%. Après régression logistique, les facteurs suivants ont été associés à la présence d'une HTAP: âge (p=0,0024), le taux hémoglobine de base (p=0,032), le taux d'hémoglobine fœtale (p=0,011), le type SS (p=0,040), la dilatation de l'oreillette gauche (p=0,0012) et la dilatation de ventricule droit (p=0,047). Après comparaison, L'hémoglobinose SS s’était avérée plus sévère. Conclusion La drépanocytose est une pathologie sévère dont le pronostic est aggravé par l'atteinte cardiaque. PMID:25368734

    La pubalgie du sportif de haut niveau représente une entité nosologique à part entière, tant en raison du mécanisme à l'origine de la pathologie que des lésions objectivables au niveau de la paroi abdominale. C'est un syndrome douloureux de la région inguino-pubienne qui touche particulièrement les footballeurs. Son étiologie est attribuée à la répétition de mouvements des membres inférieurs et du tronc associant rotation et adduction forcées. Son incidence est nettement plus élevée chez les hommes. Après avoir écarté une pathologie d'organe, le patient devrait bénéficier tout au début de son traitement conservateur d'une IRM afin d'effectuer un bilan lésionnel complet qui, selon les situations, permet d’écourter le traitement conservateur et de proposer un traitement chirurgical optimal. Le traitement doit être résolument conservateur pendant 3 mois. La rééducation est le plus souvent le traitement de première intention. Les patients présentant une persistance des symptômes sont candidats à la chirurgie. L'intervention de Nesovic est le traitement de choix chez les sportifs de haut niveau et qui permet, dans la très grande majorité des cas, une reprise sans aucune limitation de l'activité sportive antérieure. La technique de Bassini semble être moins lourde que celle de Nesovic, puisqu'elle est moins invasive. Une prise en charge multidisciplinaire centrée sur l'athlète avant et après l'intervention permet un retour aux activités physiques après quelques mois. Nous rapportons l'expérience de la prise en charge de 128 joueurs opérés selon la technique de Bassini et nous comparons nos résultats avec celles de la littérature. PMID:26966484

    Le dermatofibrosarcome (DFS) est une tumeur fibreuse de la peau, de croissance lente, à très haut risque de récidive locale, mais à potentiel métastatique faible. A partir d'une étude rétrospective étalée sur une période de 5 ans (décembre 2008 - décembre 2013), nous avons analysé les caractéristiques épidémiologiques et cliniques, le délai de diagnostic, le type de thérapeutique et le devenir de 32 patients présentant des tumeurs de Darier et Ferrand histologiquement prouvées. Parmi les 32 patients, 10 se sont présentés initialement au service pour une récidive tumorale. Une discrète prédominance masculine a été notée. Les DFS touchent préférentiellement l'adulte jeune. Le délai diagnostique observé est en moyenne de 4 ans. Le tronc est la localisation préférentielle (60%), suivi par les extrémités proximales (30%). Les 32 patients ont été traités par exérèse chirurgicale avec une marge de 5cm en surface, emportant en profondeur une barrière anatomique saine. La couverture de la perte de substance (PDS) a été réalisée après confirmation anatomopathologique du caractère carcinologique de l'exérèse, et a fait appel à différents moyens allant de la greffe cutanée aux lambeaux musculo –cutanés libres. L’évolution a été marquée par la survenue d'une récidive tumorale chez 8 patients (3 cas parmi les tumeurs vues en première intention et 5 cas parmi les tumeurs vues en récidive) et les résultats ont été jugés satisfaisants sur le plan esthétique et fonctionnel. Le DFS de Darier et Ferrand est une tumeur dont le pronostic et le risque évolutif sont principalement liés au délai diagnostic et la qualité de la première exérèse. Le diagnostic tardif, rend difficile la chirurgie d'exérèse et de reconstruction Les possibilités de guérison en cas de chirurgie primaire bien conduite sont significativement supérieures à celles d'une chirurgie de rattrapage.

    Full Text Available Parmi les facteurs abiotiques conditionnant la survie au cours de la vie embryonnaire et larvaire des poissons, le pH semble jouer un rôle primordial. La motivation de ce travail provient d'observations sur les importantes variations de ses valeurs au printemps, l'existence de pH très acides en étangs forestiers et des mortalités importantes de brochetons au cours de la même période. L'expérimentation s'est déroulée en aquariums avec une gamme de valeurs allant de 4,5 à 10,5 unités pH. Des tests en bains, continus ou momentanés (1 heure, sont effectués. Deux stades sont étudiés : les oeufs fécondés suivis jusqu'après l'éclosion ; les alevins incubés à pH neutre suivis jusqu'à la résorption de la vésicule vitelline. Les paramètres suivants sont étudiés : survie, déroulement de l'embryogenèse, anomalies éventuelles, performances de nage. Le rythme cardiaque de l'embryon a été mesuré. Les résultats sont les suivants : - Les valeurs létales sont respectivement de 6 et 10 (alevins et 4,5 et 10,5 (embryons. - L'action sur les oeufs est moins forte, même si une mortalité importante (46,7 % et de faibles performances de nage pour un pH inférieur à 6 semblent hypothéquer la réussite du recrutement. La valeur de 10,5 provoque un développement déficient des quelques individus survivants. - Sur les alevins, même en bains d'une heure, la survie est faible : 42,6 % à pH 5, 29,3 % à pH 10. Le rythme cardiaque ne variait pas de façon notable entre les seuils de tolérance. Ces résultats permettent de récapituler pour une espèce largement distribuée les conditions de recrutement liées à l'acidité du milieu. Il faut noter que les hausses brutales du pH au printemps dans des plans d'eau sur substrat cristallin rendent aléatoires la réussite des empoissonnements en brochetons des premiers stades.

    Objective: The aim of this prospective study is to assess the pertinence of using {sup 123}I-mibg myocardial tomo-scintigraphy coupled with perfusion scintigraphy as a diagnostic tool, to discriminate between multiple system atrophy (M.S.A.) and idiopathic Parkinson's disease (P.D.) at first guided by clinical data and L-DOPA tests. Material and methods: Forty patients, aged from 43 to 78 years (median 62 years) with Parkinson's syndrome were studied. Nineteen had a diagnosis of P.D. (criteria of brain bank) and 21 A.M.S. (Gibbs criteria). All were given test to acute L-DOPA. Chest-centered planar imaging (128 x 128 matrix, 5 minutes of duration) is performed at 1 hour and 4 hours after injection of 220 MBq of {sup 123}I-mibg, in addition a non-synchronized tomo-scintigraphy (64 x 64 matrix, 32 images of 50 seconds, zoom 1.45) was performed after the 4. hour and 15 minutes after injection of 200 to 400 MBq of {sup 99m}Tc-tetrofosmin. Besides neurological data, the parameters retained for comparison purposes with {sup 123}I-mibg cardiac tomo-scintigraphy were patients age, duration of disease and L-DOPA test results. Two regions of interest (R.O.I.) identical in size and in shape are used for {sup 123}I-mibg uptake quantifications (H/M and washout [W.o.]). The first one was placed in projection of mediastinum (M) and the other one in projection of heart (H). Results: We found an overall decreased uptake of the myocardial {sup 123}I-mibg without perfusion abnormality in 15 of 19 patients with P.D. and 11 among them were L-DOPA sensitive (L-DOPA test greater than 30%). Normal tracer uptake with {sup 123}I-mibg associated with an almost quite normal perfusion was seen in 15 of 21 patients with M.S.A. and they were little or not L-DOPA sensitive (L-DOPA test less than 30%). Therefore, 10 discordant cases (25%) between cardiac scintigraphy and clinical evolution of disease with also discordant L-DOPA tests were observed. In the P.D. group, quantification of data enhanced the diagnostic decision with low heart to mediastinum ratio (H/M) (1.32 +- 0.15 at the early stage and 1.25 +- 0.13 at the later stage). In the M.S.A. group, the uptake of {sup 123}I-mibg (1.66 +- 0.43 at the early stage and 1.72 +- 0.42 at the later stage) was comparable to literature data, however, with significant inter-individual variations. The association of data of scintigraphy with L-DOPA test allows to improve sensitivity in 84% and specificity in 90.5%. Conclusion: Our prospective study of 40 cases shows the relevance of cardiac sympathetic post-ganglionic imaging with {sup 123}I-mibg coupled with myocardial perfusion scintigraphy to discriminate between M.S.A. and P.D. with a higher sensitivity (71.4%) compared to the test with L-DOPA but a lower specificity (78.9%) than the L-DOPA. The difficulty of diagnosis is firstly linked to damage occurring to both the pre- and post-ganglionic sympathetic systems in patients with M.S.A. and secondly to the integrity of the sympathetic nerve endings in patients with P.D.. However, the association of data of scintigraphy with L-DOPA test show a significant improvement of sensibility (84%). (authors)

    The positron computed tomography (PET) with {sup 18}F.D.G. is today a key examination in oncology, but its use in the exploration of cardiac tumors is not actually established. The PET enlightened a hyper-metabolic injury of the left auricle, reaching to the right pulmonary veins, associated to numerous hyper-metabolic centres: hepatic, osseous and muscular ones. A muscular adjusted biopsy enlightened a metastatic fibrosarcoma. An adapted neoplastic treatment was established. This observation illustrates the potential interest of the PET with {sup 18}F.D.G. in the diagnosis of malignancy of cardiac tumor injuries and their eventual extension evaluation. (N.C.)

    Ionizing radiation may interfere with electric components of pacemakers or implantable cardioverter defibrillators. The type, severity and extent of radiation damage to pacemakers, have previously been shown to depend on the total dose and dose rate. Over 300,000 new cancer cases are treated yearly in France, among which 60% are irradiated in the course of their disease. One among 400 of these patients has an implanted pacemaker or defibrillator. The incidence of pacemaker and implanted cardioverter defibrillator increases in an ageing population. The oncologic prognosis must be weighted against the cardiologic prognosis in a multidisciplinary and transversal setting. Innovative irradiation techniques and technological sophistications of pacemakers and implantable cardioverter-defibrillators (with the introduction of more radiosensitive complementary metal-oxide-semiconductors since 1970) have potentially changed the tolerance profiles. This review of the literature studied the geometric, dosimetric and radiobiological characteristics of the radiation beams for high energy photons, stereotactic irradiation, proton-therapy. Standardized protocols and radiotherapy optimization (particle, treatment fields, energy) are advisable in order to improve patient management during radiotherapy and prolonged monitoring is necessary following radiation therapy. The dose received at the pacemaker/heart should be calculated. The threshold for the cumulated dose to the pacemaker/implantable cardioverter-defibrillator (2 to 5 Gy depending on the brand), the necessity to remove/displace the device based on the dose-volume histogram on dosimetry, as well as the use of lead shielding and magnet are discussed.

    Despite the increasingly high rate of implantation of pacemakers (PM) and cardioverter-defibrillators (ICD) in elderly patients, data supporting their clinical and cost-effectiveness in this age stratum are ambiguous and contradictory. We reviewed the data regarding the applicability, safety, and effectiveness of the conventional pacing, ICD and cardiac resynchronization therapy (CRT) in elderly patients. Although peri-procedural risk may be slightly higher in the elderly, the procedure of implantation of PMs and ICDs is still relatively safe in this age group. In older patients with sinus node disease, a general consensus is that dual chamber pacing, along with the programming of an algorithm to minimise ventricular pacing is preferred. In very old patients presenting with intermittent or suspected AV block, VVI pacing may be appropriate. In terms of correcting potentially life-threatening arrhythmias, the effectiveness of ICD therapy is comparable in older and younger individuals. However, the assumption of persistent ICD benefit in the elderly population is questionable, as any advantage of the device on arrhythmic death may be attenuated by a higher total non-arrhythmic mortality. While septuagenarians and octogenarians have higher annual all-cause mortality rates, ICD therapy may remain effective in selected patients at high risk of arrhythmic death and with minimum comorbidities despite advanced age. ICD implantation among the elderly, as a group, may not be cost-effective, but the procedure may reach cost-effectiveness in those expected to live >5-7 years after implantation. The elderly patients usually experience a significant functional improvement after CRT, similar to that observed in middle-aged patients. Management of CRT non responders remains globally the same, while considering a less aggressive approach in terms of re interventions (revision of LV lead placement, addition of a RV or LV lead, LV endocardial pacing configuration). Overall, age, comorbidities and comprehensive geriatric assessment should be the decisive factor in making a decision on device implantation selection for survival and well-being benefit in elderly patients.

We reviewed the data regarding the applicability, safety and effectiveness of conventional pacing, ICDs and cardiac resynchronization therapy (CRT) in elderly patients. Although periprocedural risk may be slightly higher in the elderly, the implantation procedure for PMs and ICDs is still relatively safe in this age group. In older patients with sinus node disease, the general consensus is that DDD pacing with the programming of an algorithm to minimize ventricular pacing is preferred. In very old patients presenting with intermittent or suspected atrioventricular block, VVI pacing may be appropriate. In terms of correcting potentially life-threatening arrhythmias, the effectiveness of ICD therapy is similar in older and younger individuals. However, the assumption of persistent ICD benefit in the elderly population is questionable, as any advantageous effect of the device on arrhythmic death may be attenuated by higher total non-arrhythmic mortality.

Elderly patients usually experience significant functional improvement after CRT, similar to that observed in middle-aged patients. Management of CRT non-responders remains globally the same, while considering a less aggressive approach in terms of reinterventions (revision of left ventricular [LV] lead placement, addition of a right ventricular or LV lead, LV endocardial pacing configuration). Overall, physiological age, general status and comorbidities rather than chronological age per se should be the decisive factors in making a decision about device implantation selection for survival and well-being benefit in elderly patients.

    To evaluate the interest of proton T 2 measurement of skeletal muscle at rest and with exercise in patients with chronic heart failure, we performed associated measurements of proton T 2 using magnetic resonance imaging, of external work using ergometry, and of intra-cellular pH (pH) using magnetic resonance {sup 31} P-spectroscopy, in skeletal muscle of the leg anterior compartment, in 37 patients with chronic heart failure. Sixteen patients were in New York Heart Association class II (NYHA II, moderate cardiac failure) and 21 in NYHA classes III-IV (severe cardiac failure). Rest T 2 was significantly increased in NYHA III-IV patients (30.9 {+-} 2.2 versus 32.8 {+-} 209 ms, p < 0.01). For these very different work levels, T 2 variations in both groups were of 23 {+-} 8 versus 21 {+-} 9, p =3D NS and pH{sub i} variations were of -8 {+-} 4 versus -9 {+-} 5%, p =3D NS. The ratio of relative T 2 variations to W was significantly increased in NYPH III-IV patients (0.24 {+-} 0.12 versus 0.60 {+-} 0.41%/J, p < 0.02). Variations of T 2 and of pH{sub i} with exercise were coupled with external work, only in group NYHA II. T 2 variations negatively correlated with those of pH{sub i} in both groups (r=3D -0.78, p<0.01 in NYHA II patients and r=3D -0.60, p<0.01 in NYHA III-IV patients). In conclusion, rest T 2 of skeletal muscle, as well as exercise-related proton T 2 variation as a function of work level, allow to evaluate the degree of severity of heart failure. A coupling is obtained between T 2 and pH{sub i} variations with exercise which seems to depend on the exercise intensity level. (authors). 22 refs., 3 figs., 2 tabs.

    2015-01-01

    Summary Les situations de catastrophe impliquant un grand nombre de brûlés peuvent survenir à tout moment après un incendie, une attaque terroriste, une explosion industrielle ou un accident de transport. Les différentes sociétés internationales de brûlologie ont publié des recommandations sur la préparation à l’afflux massif de brûlés. La Société Française d’Étude et de Traitement des Brûlés (SFETB) propose le triage des victimes selon la Surface Cutanée Brûlée (SCB), l’inhalation de fumées et les lésions traumatiques associées. Ce plan cherche à catégoriser les victimes et à attribuer à chaque patient un lit adapté à ses besoins thérapeutiques (centre des brûlés, réanimation médicale ou chirurgicale, service d’urgences, chirurgie, poste de triage). Les Services d’Aide Médicale Urgente (SAMU) sont au coeur du dispositif : premiers soins, poste Médical Avancé (pMA), régulation, triage et transport, renfort en matériel dans l’hôpital de proximité. Un plan catastrophe pour brûlés doit être adapté aux capacités hospitalières du pays. PMID:26668563

    A 30-year-old woman, with a history of nasopharyngeal carcinoma, which was treated by radiotherapy nine years previously, presented with occasional diplopia and recent headaches. A nasopharyngeal biopsy showed no recurrence. The imaging revealed a sphenoidal sinus mucocele. Endoscopic marsupialization of the mucocele allowed clinical improvement. A 56-year-old woman presented, five years after radiotherapy for nasopharyngeal carcinoma, with a fronto-orbital mass. CT-scan revealed a fronto-ethmoidal mucocele. Nasopharyngeal biopsy showed tumour recurrence. Marsupialization of mucocele was performed. Recurrence of the carcinoma was treated by radiotherapy and chemotherapy. Sphenoidal sinus mucocele developing after radiotherapy for nasopharyngeal carcinoma has rarely been reported. CT scan and MRI are useful tools in making the diagnosis. Biopsy is required to diagnose recurrence or associated radio-induced tumor. Endoscopic approach gives good results. (authors)

    Les PFW sont des nappes polaires installées sur les pôles des aimants du PS. Elles sont au nombre de 4 par unité d'aimant et constituées d'un circuit principal (dans lequel circule le courant désiré selon le cycle magnétique utilisé) et de circuits auxiliaires. Les circuits auxiliaires sont des enroulements de correction (boucles de tour et ?pick-up? brasés sur les enroulements principaux). Pendant la variation du champ magnétique de l'aimant PS, on utilise des tensions induites dans ces circuits auxiliaires pour corriger les erreurs de champ dues aux pertes par courants de Foucault dans la chambre à vide. Chaque année, pendant l'arrêt machine, on vérifie si les caractéristiques des circuits auxiliaires correspondent aux normes (mesures des résistances des boucles de tours, résistances entre ?pick-up? et isolation des circuits) afin de faire un suivi. Des mesures ont été faites au début du grand arrêt en décembre 2004 afin de définir quels aimants seraient à rénover (l'état des PFW e...

    About 30% of patients who underwent percutaneous transluminal coronary angioplasty show evidence of restenosis, which appears to be independent of the angioplasty method used. The restenosis is due of two factors, Firstly migration of smooth vascular muscle cells of the vascular media to the intima and multiplication which lead to the formation of a neo-intima. Irradiation limits the proliferation by acting of the cells in the mitotic stage. The vascular target volume is not very thick and is difficult to define it, that why brachytherapy seems to be the best procedure to prevent restenosis. However, the development of this treatment present many difficulties. Different irradiation techniques have been studied. Such techniques include catheter containing radioactive sealed source, radioactive stent, or balloon containing radioactive liquid inside. Each of these methods have their own advantages, inconveniences, problems and risks. Radioisotope may be either beta or gamma emitters.Gamma emitter presents problems for radioprotection but the satisfactory dose distribution may be difficult to obtain using beta emitter. Choice of dose, dose rate and delay between the end of angioplasty and the beginning of brachytherapy is subject to some discuss. Animal experiments using radioisotope have shown reduction in cell proliferation. Human trials showed feasibility, safety of the method and real impact on restenosis prevention. However, long-term efficacy has not been proved because the follow-up of the patients is too short. A randomized trial of {sup 192}Ir brachytherapy for prevention of restenosis has recently shown the efficacy in short and median term. However, long term efficiency and secondary effects have not yet been established as the follow up time of this study is still too short. That is why, collaboration between cardiologists and radiotherapists and physicists is indispensable to enable the development of an optimal technique. (authors)

    Full Text Available Illegal rosewood logging has known a strong increase in 2009, following two inter-ministerial texts legalizing exports of precious wood. National parks are specifically affected by this exploitation. It is of course very difficult to know the real situation concerning exploitation but also exports. This paper presents and discusses information about “illegal” exports. Firstly, after a recall of the legal context, it underlines the difficulties in collecting information. Several reasons are underlined: the size of container, the density of wood, the diversity of material (log, board, etc, the place of shipment, the filling up of containers, and under-declaration for fiscal reasons. Nevertheless, even if exports estimations are probably far from the reality, the equivalent of around 1,202 containers, representing a value of more than US$ 220,000,000 are listed. Secondly, it analyzes also traffic regulation systems. More specifically, it proposes a parallel between the regulation of ivory traffic and the regulation of precious wood traffic in Madagascar. It concludes that the process of garnishment with resale by auction has very few chances to be efficient. The ivory case shows that reinforcing processes of garnishment do not succeed in stopping the traffic. It rather provokes reorganizations of the value chain. In the long term, the sole solution will be the development of a sustainable labeled chain for precious wood. European Union Due Diligence Regulation and Lacey Act in United States participate in the strengthening of control on precious wood.

    Cornette, J.B.

    1992-02-01

    Candidate pulsed power systems for electromagnetic launchers constitute two broad categories: rotating machinery and non-rotating devices. Rotating machinery for this purpose is under development at several industrial and educational institutions around the world. Non-rotating hardware includes capacitors, batteries, and inductors. These, too, are the subject of research programs, but as yet, are much larger than rotating supplies of equal power and energy capability. In 1988, system studies identified several attractive pulsed power systems for electromagnetic launchers. Battery charged capacitor pulsed power systems were among those identified as promising for electromagnetic launcher systems. The basic equations governing the battery charging capacitor sequence, and the capacitor discharge into an electromagnetic launcher are the subject of this report. A battery charged capacitor system powering an electromagnetic launcher has also been built and tested. This experiment not only validates the system concept with presently available hardware, but can be used to establish a baseline for evaluation of future systems when technology in capacitor and battery power and energy densities improve.

    Full Text Available La crise a eu, sur les taux de croissance des pays en développement ou émergents, des effets plus dévastateurs que sur ceux des nations industrialisées. Alors que certains n’avaient pas les ressources nécessaires pour financer des mesures de relance assez vigoureuses, les grands pays émergents ont vite retrouvé le chemin de la reprise et sont actuellement les principaux moteurs de l’économie mondiale.L’effondrement des flux de capitaux privés a provoqué un déficit croissant dans le financement global du Sud. Et jusqu’à présent, pas plus l’augmentation des flux financiers publics que la lente reprise – depuis la fin 2009 – des apports de capitaux privés n’ont permis de compenser ces manques. L’ONU indique par ailleurs que le volume global des mouvements financiers des pays du Sud vers ceux du Nord dépasse celui des flux en sens contraire : le Sud continue de financer le Nord.Alors que l’on débat désormais d’une réforme de l’ordre économique et financier mondial, cela n’a pas encore été suivi d’effets suffisants pour les pays en développement. Les institutions financières internationales disposent bien de ressources accrues, mais les pays en développement y sont toujours sous-représentés. Le FMI et la Banque mondiale ont remis en question certains de leurs dogmes traditionnels, sans que l’on puisse parler à coup sûr de nouvelle politique.Il apparaît toujours plus évident que les impôts jouent un rôle central dans la mobilisation de ressources locales pour financer le développement et l’on reconnaît d’une manière générale qu’il faudra réformer dans ce sens la fiscalité des pays en développement. Cependant, l’aide technique des pays industrialisés en vue de réaliser ces réformes reste insuffisante. De même, il est de plus en plus admis que les impôts sont un instrument pour la construction de l’Etat (state-building, la démocratisation et la gouvernance. La lutte contre l’évasion fiscale à l’échelle internationale et les flux illicites de capitaux (illicit capital flows a gagné en vigueur et l’on voit s’améliorer les échanges d’informations en matière fiscale.

    2011-05-01

    Full Text Available L’Inde est un pays démocratique d’une extraordinaire diversité. Sa croissance économique est l’une des plus rapides au monde. C’est le sixième plus grand consommateur mondial d’énergie. Ses politiques et ses stratégies énergétiques suscitent un intérêt de plus en plus important en raison de leur impact considérable sur les relations géopolitiques, sur les prix mondiaux de l’énergie et sur les changements climatiques. Actuellement, sa consommation d’énergie per capita et ses valeurs d’émissions de gaz à effet de serre sont faibles. Cependant, elles sont vouées à augmenter si le pays emprunte la même trajectoire de développement que l’Occident. Pour que l’Inde saute par-dessus ces sentiers déjà souvent battus pour en atteindre un qui garantisse un développement durable, le pays doit impérativement redéfinir son paradigme de développement de sorte à assurer une croissance inclusive. Des subventions inviables, une mise en œuvre des réformes laissant à désirer, des prix énergétiques faussés et des investissements inadaptés dans des énergies renouvelables sont quelques-unes des principales entraves que le gouvernement indien doit réexaminer afin d’améliorer la sécurité énergétique et de fournir un cadre de transition vers une économie à faible intensité de carbone. Outre des politiques énergétiques innovatrices telles que la Mission solaire nationale (National Solar Mission, la Mission nationale pour l’amélioration de l’efficacité énergétique (National Mission on Enhanced Energy Efficiency et la Mission nationale pour l’habitat durable (National Mission on Sustainable Habitat, l’Inde a besoin d’adopter un cadre de croissance découplée, que nous considérons comme une amélioration de la qualité de vie des citoyens sans pour autant intensifier les dommages à l’environnement. Depuis 2008, l’Inde démontre qu’elle prend au sérieux le changement de son modèle de croissance et le passage à des énergies propres. Néanmoins, ces perspectives ne se réaliseront pas pleinement si l’hémisphère Nord n’apporte pas une aide technique et financière pour atténuer collectivement les effets nuisibles du réchauffement de la planète et des changements climatiques qu’il provoque.

    Purpose. - To assess the benefit of breast surgery for inflammatory breast cancer. Patients and methods. - This retrospective series was based on 232 patients treated for inflammatory breast cancer. All patients received primary chemotherapy followed by either exclusive radiotherapy (118 patients, 51%) or surgery with or without radiotherapy (114 patients, 49%). The median follow-up was 11 years. Results. - The two groups were comparable apart from fewer tumors smaller than 70 mm (43% vs 33%, P = 0.003), a higher rate of clinical stage N2 (15% vs 5%, P = 0.04) and fewer histopathological grade 3 tumors (46% vs 61%, P < 0.05) in the no-surgery group. The addition of surgery was associated with a significant improvement in locoregional disease control (P = 0.04) but with no significant difference in overall survival rates or disease-free intervals. Late toxicities were not significantly different between the two treatment groups except for a higher rate of fibrosis in the no-surgery group (P < 0.0001), and more lymphedema in the surgery group (P = 0.002). Conclusion. - Our data suggest an improvement in locoregional control in patients treated by surgery, in conjunction with chemotherapy and radiotherapy, for inflammatory breast cancer. (authors)

  6. The Party's Over: Oil, War And The Fate Of Industrial Societies; Petrole la fete est finie. Avenir des societes industrielles apres le pic petrolier

    Energy Technology Data Exchange (ETDEWEB)

    Heinberg, R

    2008-07-01

    The world is about to run out of cheap oil and change dramatically. Within the next few years, global production will peak. Thereafter, even if industrial societies begin to switch to alternative energy sources, they will have less net energy each year to do all the work essential to the survival of complex societies. We are entering a new era, as different from the industrial era as the latter was from medieval times. In 'The Party's Over', Richard Heinberg places this momentous transition in historical context, showing how industrialism arose from the harnessing of fossil fuels, how competition to control access to oil shaped the geopolitics of the twentieth century and how contention for dwindling energy resources in the twenty-first century will lead to resource wars in the Middle East, Central Asia and South America. He describes the likely impacts of oil depletion and all of the energy alternatives. Predicting chaos unless the United States-the world's foremost oil consumer-is willing to join with other countries to implement a global program of resource conservation and sharing, he also recommends a 'managed collapse' that might make way for a slower-paced, low-energy, sustainable society in the future. More readable than other accounts of this issue, with fuller discussion of the context, social implications and recommendations for personal, community, national and global action, Heinberg's updated book is a riveting wake-up call for human-kind as the oil era winds down, and a critical tool for understanding and influencing current US foreign policy.

    On April 26, 1986, the reactor no.4 of the Chernobyl power plant (Ukraine) exploded. The real human impact of this catastrophe is still unknown. Today, 1.4 million people, included 260.000 children, are living in contaminated areas. What is the population situation of these areas and what are the actual health problems encountered? Written by scientists who have worked for 25 years in contaminated areas, this book follows two goals: - providing the reader with verified and reliable information about the accident impacts on public health and demography; - proposing a remedial action plan aiming at improving the health of the populations living in the contaminated areas (named 'model of life system in a radioactivity contaminated territory').

Ce corpus a été enregistré par dix locuteurs francophones (5 hommes et 5 femmes et la durée segmentale de chaque triplés, relevée de manière systématique, a fait l’objet d’un traitement statistique sous R. Les résultats des différentes ANOVA suggèrent un allongement significatif du [s] des clusters dérivés par rapport aux clusters lexicaux. Dans un cadre strictement CV (Lowenstamm 1996, Scheer 2004, cet allongement peut découler de la différence de structure prosodique qui existe entre ces deux types de clusters.

    Objectives: To determine prospectively the factors associated with reconstruction failure (i.e. requiring expander removal) and capsular contracture in patients undergoing mastectomy and immediate two-stage breast reconstruction with a tissue expander and implant, and radiotherapy for breast cancer. This is a multi-institutional prospective non-randomized trial. Patients and Methods: Between 2/1998 and 9/2006, we prospectively evaluated 141 consecutive patients who received 141 implants after mastectomy and underwent chest wall radiotherapy (46 to 50 Gy in 23 to 25 fractions). Patients were evaluated after 24 to 36 months by two senior physicians (radiation oncologist and surgeon). Results: Medical follow-up was 37 months. Baker 1 and 2 capsular contracture was observed in 67.5% of patients, Baker 3 and 4 in 32.5%. There were 32 reconstruction failures. In a univariate analysis, the following factors were associated with Baker 3 and 4 capsular contracture: surgeon, use of hormonotherapy and smoking, of which only one remained in the multivariate analysis: surgeon. In a univariate analysis, the following factors were associated with reconstruction failure: tumor size T3 or T4, smoking, pN+ axilla. Three factors remained associated with reconstruction failure in a multiple logistic regression: large tumors T3/T4, smoking and pN+ axilla. Conclusions: Mastectomy, radiotherapy and immediate breast reconstruction with a tissue expander and implant should be considered when breast conserving surgery has been denied. Adequate patients can be easily selected by using three factors of favourable outcome. (authors)

    Several epidemiological studies enlightens an increase of the number of thyroid cancers among children and adolescents exposed to ionizing radiation after an internal exposure ( Chernobylsk accident) or external one as a radiotherapy. No increase arose for adults.The analysis of the transcriptome was realised with micro arrays prepared on the genomic platform of the Cea at Evry that allow to study simultaneously the expression of 6000 genes. this study allows to enlighten a signature of radioinduction constituted by series of genes specifically expressed in one or other type of cancer in function of its etiology. This signature includes 59 genes expressed differentially between the sporadic carcinomas and 45 genes in the case of adenomas. with this signature an analysis in principal components allowed to determine correctly the etiology of 12 tumors among 13, the etiology of a sporadic adenoma was not determined. Besides, the study of the expression of genes specific to thyroid (TSHR, TG, TPO, TTF1, TTF2, PAX8) in relation with the presence of arrangements RET/PTC or mutations of BRAF was made. It allowed to enlighten the loss of TPO expression in the cancers changed for BRAF as well as a new mechanism of BRAF activation. (N.C.)

    The Services Industriels of Geneve (SIG) acted as a pioneer when in 1993 they purchased and commenced the operation of a first generation phosphoric acid fuel cell ONSI PC25A. The object of the SIG fuel cell pilot project, Gazel, is to promote the technology of fuel cells powered by natural gas, by demonstrating the feasibility of exploitation of the technique, and by seeking to optimize profitability conditions in an installation on an industrial scale. For almost four years, the operational results obtained conform to, and in some cases even exceed, the initial estimates, which were already very favourable in comparison with traditional technologies of electricity production. Indeed, ecological and technical performances more than corresponds to the manufacturer expectations. Long duration tests should allow to evaluate the profitability of the fuel cell, justly considered to be a technology of the future for the gas industry. (orig.) [Deutsch] Im Jahre 1993 haben die Industriellen Betriebe in Genf (SIG) auf eigene Rechnung die Brennstoffzelle PC25A von ONSI erworben und als erste deren regulaeren Betrieb aufgenommen. Mit diesem Projekt hatten die SIG sich zum Ziel gesetzt, die Brennstoffzellen-Technologie zu lancieren. Erdgas wird zur Speisung der Brennstoffzelle benutzt, und das Projekt ist eine Demonstration des zuverlaessigen Betriebs dieser Technologie, mit dem im industriellen Massstab die Rentabilitaetsbedingungen reell optimiert werden. Die in den beinahe vier Jahrzehnten Betriebsdauer erzielten resultate entsprechen voll den Erwartungen und uebertreffen in einzelnen Details die urspruenglichen Vorgaben, die im Vergleich zu den herkoemmlichen Technologien der Elektrizitaetserzeugung bereits sehr viel guenstiger sind.

    2002-05-01

    The precise assessment of sexual dysfunction after treatment of prostatic cancer cannot be avoided in 2002. These iatrogenic complications may significantly alter the quality of life of the patients. In addition, sexual toxicity is progressively becoming a cardinal parameter for the treatment choice, both for the patient and the physician. Significant efforts allowed to reduce sexual toxicity after therapy in the recent years. As an example, nerve-sparing surgical techniques have been proposed, whenever reasonable. However, in spite of these surgical advances, data suggest that overall, the new irradiation techniques (conformal radiotherapy and brachytherapy) are responsible for less alteration of sexual life than surgery. Another potential advantage is that sildenafil (Viagra) is able to restore potency in a majority of cases after radiotherapy, while it is usually poorly effective after surgery. (author)

    Caesium-137 ({sup 137}Cs) is a radionuclide present in the environment mainly as the result of the atmospheric nuclear weapons testing and accidents arising in nuclear power plants like the Chernobyl accident in 1986. Nowadays, the health consequences resulting from a chronic exposure to this radionuclide remain unknown. After absorption, the caesium is distributed relatively homogeneously within the body, with a more important load in children than in adults. The toxicity of {sup 137}Cs is mainly due to its radiological properties. A high dose of {sup 137}Cs is responsible for a medullar dystrophy, disorders of the reproductive function, and effects on liver and renal functions. Disorders of bone mineralization and brain damages were also described in human beings. At lowest dose, {sup 137}Cs induces disturbances of wakefulness-sleep cycle, but not accompanied with behavioural disorders. The cardiovascular system was also perturbed. Biological effects of {sup 137}Cs on the metabolisms of the vitamin D, cholesterol and steroid hormones were described, but do not lead to clinical symptoms. In human beings, {sup 137}Cs leads to an immune deficiency, congenital and foetal deformations, an increased of thyroid cancer, as well as neurological disorders. It seems that children are more sensitive to the toxic effects of caesium than the adults. At present, the only effective treatment for the decorporation of the ingested {sup 137}Cs is the Prussian Blue (Radiogardase). The use of pectin to de-corporate the ingested {sup 137}Cs, in children notably, is sometimes proposed, but its administration still remains an open question. To conclude, the available scientific data suggest that {sup 137}Cs could affect a number of physiological and metabolic functions and consequently, could participate in the health risks associated to the presence of other contaminants in the environment.

The state has the responsibility of setting penalties (rate rebates) in the case of a prolonged blackout and the procedures for applying them. But it must also specify the order of magnitude and length of time for the program that it wants implemented to deal with such emergencies.

    Acute mucositis is common after radiotherapy for head and neck cancers. During the past 3 decades, there was a gradual evolution in the treatment modalities for locally advanced carcinomas (concomitant radio-chemotherapy, accelerated radiotherapy). These new strategies are accompanied by an increase in early mucosal reactions. At the present time, there is no widely accepted prophylaxis or effective treatment. Many traditional remedies or new agents seem ineffective (Sucralfate, Chlorhexidine, GM-CSF, Silver nitrate, Prostaglandin, anti-oxidants, Benzydamine hydrochloride), while others seem promising (Povidone-iodine, nonabsorbable antibiotic lozenges and anti-fungal, local GM-CSF, Glutamide, Low-energy laser, corticosteroids). Radioprotectors are controversial and should be only used in experimental protocols and not in routine practice. However, some recommendations can be proposed: general prevention and global care before cancer therapy should be systematic (oral hygiene, dental and periodontal treatment, advice to avoid the use of tobacco and alcohol); frequent oral rinsing with a bland mouthwash (Povidone-iodine or others) should be used at the start of treatment because there are significant modifications of the oral microflora increased by a disturbed salivary flow; these mouthwashes could be associated with nonabsorbable antibiotic lozenges or anti-fungal topical (bicarbonates, Amphotericine B); Systematic percutaneous fluoroscopic gastrostomy should be decided before any aggressive treatments (concomitant radio-chemotherapy, accelerated radiotherapy); pain should be controlled; finally, the radiation technique should be optimized (mucosal sparing block, conformal radiotherapy and intensity modulated radiation therapy).

    Before the gulf war during 1990/1991, the Iraq petroleum production was 3.14 millions of barrels by day and its production capacity 3.5 millions of barrels by day. Exports were 2.78 millions barrels by day. Because of destruction, capacity decreased. But, with re-building, capacity increased until 2.6 Mb/day and exports until 3.5 Mb/day. New reserves were explored and 35 deposits were discovered. Iraq reserves represent 14% of OPEC reserves and 11% of world reserves. Only 15 deposits among 73 petroleum deposits are actually operating. It is envisaged to negotiate with foreign societies to share production after embargo will be removed.

    Subchannel analysis plays important role to evaluate safety critical parameters like minimum departure from nucleate boiling ratio (MDNBR), peak clad temperature and fuel centerline temperature. In this study, two different subchannel codes, VIPRE-01 (Versatile Internals and Component Program for Reactors: EPRI) and THALES (Thermal Hydraulic AnaLyzer for Enhanced Simulation of core) are examined. In this study, two different transient cases for which MDNBR result play important role are selected to conduct analysis with THALES and VIPRE-01 subchannel codes. In order to get comparable results same core geometry, fuel parameters, correlations and models are selected for each code. MDNBR results from simulations by both code are agree with each other with negligible difference. Whereas, simulations conducted by enabling conduction model in VIPRE-01 shows significant difference from the results of THALES.

    The hereditary amyloid neuropathy (HAN) is characterized by a progressive sensory-motor poly-neuropathy and a dysautonomia with myocardium sympathetic denervation. This is established by MIBL scintigraphy and may enhance the troubles of conduction and of cardiac rhythm. The amyloid deposits are constituted of anomalous pre-albumin fabricated by liver. The hepatic transplant (HT) is the only known treatment. Four patients (GI: 39 {+-} 5 years) have been studied by MIBG scintigraphy, 2.2 {+-} 0.7 years after HT, and compared with 12 patients (GII: 39 {+-} 12 years) studied before HT. The left ventricular function, the coronary arteries and the at-rest scintigraphy with thallium were normal for all of them. The cardiac capture of MIBG, evaluated by the cardio-mediastinal activity ratio (C/M), measured on an anterior thoracic planar acquisition performed 4 hours after the intravenous injection of 300 MBq, was higher for GI than for GII (1.49 {+-} 0.12 vs 1.29 {+-} 0.13, p 0.02). The washouts (4 h / 20 min) were not different. In tomography, the patients of GI presented focal anomalies with a more-or-less extended apical defect, a satisfying fixation of the basal half of the anterior wall, more-or-less overflowing the septal and lateral walls, and for 2 patients, a satisfying inferior fixation. On the contrary, 9/12 patients of GII have had a diffuse absence of fixation, the other three heaving a satisfying antero-basal fixation ({chi}{sup 2}, p = 0.05). The results are not explained by difference of severity or evolution duration of HAN. Thus, it appears that there exists a sympathetic re-innervation of myocardium after HT in the HAN, debuting by the heart base, similarly with the effect of anatomic interruption of innervation in cardiac transplants

    Nuclear dissuasion is a slow and permanent process of adjustment to the strategic environment. French dissuasion adaptation to the new international environment covers a full decade, starting in the 1989-1992 era with a re-evaluation of defense programs. It has been followed by the 1994 defense white book which opens up the European perspective and reaches its peak in 1996 with a series of major decisions: renouncement of surface-to-surface missiles, launching of the M51 program, end of nuclear tests and shift towards simulation, dismantling of fissile materials production facilities etc. This process shows up two logics: the one of continuity with the confirmation of the bases of the French nuclear doctrine, and the one of discontinuity with significant changes in the general domain of the French nuclear policy. It also opens up questions about the field of application of dissuasion and the future of the nuclear consensus. (J.S.)

  18. Etude comparative sur la propagation de l'endommagement apres impact des composites carbone/epoxy renforces par piquage au fil Kevlar et titane-nickel

    Science.gov (United States)

    Vachon, Pierre-Luc

    Composite laminates have strong in-plane mechanical properties, but they are generally weaker through their thickness. This specificity makes the laminates prone to delamination, particularly under low-velocity impact loads. Consequently numerous research efforts have been dedicated to developing interlaminar reinforcing methods, such as transverse stitching. The present project proposes the use of the stitching technique combined with a special stitching thread made of superelastic TiNi alloy. This technology is intended to improve the delamination toughness in composite laminates loaded in bending. In the first part of this study a numerical model was developed for analyzing composite structures. The 3-D finite element model was built with the ANSYS commercial software using 20-node solid and 8-node shell elements. The progressive damage modeling technique was used, allowing the prediction of delamination propagation in a laminate submitted to various loading modes. The model was validated for a plate under quasi-static traction load, and it was then used to simulate three-point bending tests. Secondly, carbon/epoxy composite panels were fabricated, with each panel containing unstitched and stitched specimens. Two different materials were used for the stitching thread: superelastic TiNi wires and Kevlar threads as a reference. Some stitched specimens were cut in slices in order to make some observations of the internal stitch using an optical microscope. Standardized low-velocity impact tests and compression after impact tests were carried out on stitched and unstitched specimens (ASTM D7136 and D7137). The Kevlar reinforcements have shown great performance in reducing the delaminated zone after impact, as well as in improving the residual compression strength. The TiNi reinforcements provided encouraging results during the impact tests, though being less effective than the Kevlar threads. During the compression after impact tests, only a slight difference could be measured between the TiNi-stitched and the unstitched specimens. Then the bending performance of the specimens was quantified experimentally by calculating the energy required to create a unit volume of damaged material (Gv, J/mm3). This metric is similar to the Strain Energy Release Rate (SERR) commonly used in studies on delamination. According to the experimental results, the damage resistance in three-point bending was not improved by the Kevlar reinforcements, despite the reduced damaged zone after the impact test. Indeed, when the strain energy in bending is relativized to the induced damaged volume during propagation, it turns out that the TiNi reinforcements are more effective than the Kevlar's for improving the damage resistance. Finally, the numerical study on the behavior of both types of stitched reinforcements allowed identifying subtle differences between those. Indeed, both stitching threads (TiNi and Kevlar) promoted the interlaminar propagation of the delamination during simulation of the bending test, with this behavior being less pronounced for the TiNi-stitched plate. However the Kevlar threads seemed more effective for stopping this propagation in the zones between the stitches. Keywords: composite materials, stitching, numerical model, shape memory alloy, three-point bending, low-velocity impact, ultrasound imaging.

La guerre du Golfe a également fait évoluer les conditions de sécurité des pays les moins développés, et les principaux vendeurs d'armes ont diminué leurs aides économiques à l'exportation des armes. A partir de l'examen de nombreux cas régionaux, l'auteur conclut que l'avenir des politiques d'armement des pays sous-développés dépend de l'ord...

    Radical prostatectomy after pelvic lymphadenectomy is an effective treatment or patients with T1-2 pN0 adenocarcinoma of the prostate. However, pathologic analysis of resected tissue reveals that in 20 to 40 % of clinical stage B lesions, the tumour has extended locally beyond the prostate. This infra-clinical disease may be the origin of local relapse. Radiation oncologists are often asked to deliver post-operative irradiation. There is sufficient evidence in the literature that postoperative radiation therapy can improve local control rate for patients with pT3 pN0 adenocarcinoma of the prostate; however, the effect of this radiotherapy on survival in this category of patients remains unclear. It is the reason why randomized clinical trials have been implemented for investigating the role of pelvic external irradiation with respect to the effects on local control, acute and late morbidity, overall survival and cancer-related survival, and for better defining the selective indications of radiotherapy, regarding pathological data.
