    Introduction la présente étude vise à déterminer la fréquence de l'asthme sévère chez les patients asthmatiques suivis au Centre National Hospitalier de Pneumo-Phtisiologie (CNHPP) de Cotonou et identifier les facteurs de risque qui lui sont associés Méthodes l’étude transversale, descriptive et analytique a porté sur 213 patients asthmatiques de la file active 2013 du CNHPP. Les données ont été collectées par l'exploitation des dossiers et l'entretien individuel avec les patients. Elles ont été traitées et analysées à l'aide des logiciels EPIINFO7 et STATA11. Le test Chi2 de Pearson, la régression logistique uni variée et multi variée ont été utilisés au seuil de signification de 0,05 Résultats au total, 154 patients asthmatiques soit 72,7% ont répondu au questionnaire. Parmi eux 20,8% (IC95%:(14,67; 28,05)) souffraient d'asthme sévère. L’âge des patients s’étendait de 10 à 76 ans avec une médiane de 41 ans; 51,3% étaient de sexe féminin, 79,9% avaient des antécédents d'allergie, 61,7% ont commencé leur asthme après l’âge de 12 ans et seuls 11% ont consommé ou consommaient du tabac. Les facteurs associés à la survenue de l'asthme sévère étaient: l’âge de 46 à 55 ans (p = 0,04); les troisième et quatrième quintiles du bien-être économique (p = 0,01) et le début de l'asthme après l’âge de 12 ans (p < 0,001) Conclusion l’étude a montré une fréquence élevée de l'asthme sévère au Bénin et permettra d'améliorer sa prise en charge au CNHPP.

    Introduction La présente étude avait pour objectif de mesurer l'ampleur des infections du per-partum à la maternité du Centre Hospitalier Départemental de l'Ouémé-Plateau d'analyser les conditions de survenue et de prise en charge dans la perspective de l'amélioration des soins et services maternels et néonataux. Méthodes Une étude descriptive et analytique a été conduite de Août 2009 à Février 2010 et a impliqué 110 mères victimes d'infections du per-partum; elles ont été soumises à un questionnaire durant tout leur séjour hospitalier; des observations des pratiques de prise en charge des prestataires de soins ont été menées et des registres et autres supports de données sanitaires ont été exploités. L'analyse des données a été effectuée à l'aide du logiciel Epi Info 6.4 dans sa version française. Résultats L'incidence des infections du per-partum était de 5,9 pour 100 accouchements (110/ 1875); les types d'infections les plus incriminés étaient les endométrites (27,3%), les chorioamniotites (18,2%), les infections du site opératoire (12,7%) et les infections urinaires (2,7%). Les examens cliniques ont été relativement acceptables. En revanche, les examens biologiques ont été très insuffisants expliquant l'imprécision importante au niveau des diagnostics. L'antibiothérapie a été instaurée systématiquement. Le taux de mortinaissance était de 25,6% et les enfants de petit poids représentaient 23,2%. Conclusion L'incidence des infections du per-partum dans la présente étude était assez élevée. Des efforts de préventions et de dépistage de ces infections sont nécessaire afin d'améliorer la qualité des soins PMID:25120854

    Notre travail avait pour objectif d’étudier les aspects épidémiologiques et écho-cardiographiques des cardiopathies congénitales au CHUP-CDG afin d'y faire l’état des lieux. Pour se faire, nous avons mené sur une période de 27 mois d'aout 2009 à mai 2010 et d'octobre 2011 à décembre 2011, une étude rétrospective des comptes rendus d’échocardiographies Doppler des patients admis dans le service d'imagerie médicale. Nous avons utilisé une sonde cardiaque de 5MHz sur appareil Aloka Prosound 4000 Plus. Durant la période d’étude, 380 examens écho-cardiographiques ont été réalisés et ont permis de mettre en évidence 109 cas de cardiopathies congénitales avec 138 entités nosologiques différentes. Les cardiopathies congénitales représentaient 0,98% des 11169 entrées. Les souffles étaient au premier rang des motifs de demande de l’échographie Doppler cardiaque (121 cas sur 380) soit 39,53%. Les CIV étaient au premier plan des cardiopathies congénitales (28,26%), suivies des CIA (23,19%), des sténoses pulmonaires (19,57%), des Tétralogie de Fallot (9,42%). Dans leur forme isolée, les CIA étaient les plus fréquentes avec 21,95% des cas, suivies des CIV avec 20,73%. Sur 138 cas de cardiopathies congénitales (chez 109 enfants), 53 cas ont été observés chez des enfants de sexe féminin et 56 cas chez des enfants de sexe masculin soit un sexe ration de 1,1. La tranche d’âge présentant une fréquence élevée de cardiopathie congénitale est celle de 1mois- 30 mois avec 55% des cas. Les cardiopathies congénitales de l'enfant sont une réalité en Afrique, leurs fréquences dans toutes les séries rapportées sont certainement sous estimées en raison de l'inaccessibilité de l’échocardiographie doppler.

    Introduction Il s'agit d'analyser la prise en charge du nouveau-né dans le cadre de la stratégie na-tionale de subvention des accouchements et des soins obstétricaux et néonatals d'urgence mis en place par le gouvernement du Burkina Faso en 2006. Méthodes Nous avons menée une étude à visée descriptive et analytique comportant un volet ré-trospectif du 01 janvier 2006 au 31 décembre 2010 portant sur les paramètres épidémiologiques, cliniques des nouveau-nés hospitalisés et un volet prospectif du 3 octobre 2011 au 29 février 2012 par une entrevue des accompagnateurs des nouveau-nés et des prestataires des services de santé. Résultats Les hospitalisations ont augmenté de 43,65% entre 2006 à 2010 Le taux de mortalité néo-natale hospitalière qui était de 11,04% a connu une réduction moyenne annuelle de 3,95%. L'entrevue a porté sur 110 accompagnateurs et 76 prestataires. La majorité des prestataires (97,44%) et des ac-compagnateurs (88,18%) étaient informés de la stratégie mais n'avait pas une connaissance exacte de sa définition. Les prestataires (94,74%) ont signalé des ruptures de médicaments, consommables médicaux et des pannes d’ appareils de laboratoire et d'imagerie. Parmi les accompagnateurs (89%) disaient être satisfaits des services offerts et (72,89%) trouvaient les coûts abordables mais évoquaient les difficultés du transport. Conclusion: La subvention a amélioré la prise en charge du nou-veau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. Conclusion La subvention a amélioré la prise en charge du nouveau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs. PMID:26161166

We analyzed the waiting list at the Centre hospitalier de l'Université de Montréal (CHUM Pain Centre. Methods: The present study is an observational, prospective study. We used a specifically designed survey questionnaire. Survey findings were analyzed with descriptive statistical methods. Results: A total of 270 patients were contacted; only 146 were included. Of these, 93 were women and 53 men. The average age was 55.9 years. Fifty-two percent of the patients were referred by a medical specialist; 34% by family physicians; 3% for emergency; and 11% unknown. The mean for pain score was 6.7/10. Seventy-three percent were taking pain killers with an average improvement on their pain score of 52%. Ten percent of respondents were not taking any type of analgesic medication, while 17% were taking over-the-counter drugs. Fifty-three percent of the patients had been suffering from chronic pain for 5 years or less, while 10% had been suffering and awaiting specialized pain treatment for more than 20 years. Conclusion: Our data suggests that accessibility to specialized health care is not the sole obstacle to the timely and effective management of chronic pain. Seventy-three percent of the patients were taking some form of pharmaceutical treatment for pain and reported an average improvement rate of 52% on their pain score under medication. Such inconsistency may be attributable to patients' lack of compliance with their treatment. The World Health Organization Working Group recommended in chronic patients a novel approach to health care, based on patient

    Introduction Les accidents vasculaires cérébraux constituent un véritable problème de santé publique en Afrique avec une charge importante. Les données fiables sur sa réelle charge économique sont rares en Afrique. L'objectif de cette étude était d’évaluer le coût direct hospitalier des AVC à Parakou au Bénin. Méthodes Il s'agissait d'une étude transversale économique ayant inclus des patients hospitalisés pour un AVC à l'hôpital de Parakou entre le 1er Juin 2010 au 31Mai 2011. Les données concernant les différents postes de consommation ont été collectées selon la méthode dite bottom-up. Le coût était envisagé du point de vue de la société et du patient. L'unité du coût était le franc CFA (valeur en 2011). Une régression linéaire multiple était utilisée pour déterminer les meilleurs prédicteurs du coût. Résultats Ils étaient 78 patients dont 52 hommes, âgés en moyenne de 57 ans ± 10.9. Le NIHSS moyen était de 14,4. Le taux de mortalité était de 20,5%. Le coût direct moyen était de 316.810,3 (±230.774,8) F CFA (environ 704 ± 512 Euros). Les grands postes de consommation étaient les explorations paracliniques (34.3%) les soins et médicaments (28.4%) et les frais d'hospitalisation (17.9%). Les meilleurs prédicteurs du coût élevé étaient un AVC hémorragique, un NIHSS élevé à l'admission et une longue durée d'hospitalisation. Conclusion Cette étude suggère un coût élevé de la prise en charge actuelle des AVC à Parakou. PMID:24839529

    La connaissance de la physiologie de la vitamine D a considérablement progressé ces dernières années, la faisant passer de simple vitamine à tropisme purement phosphocalcique et osseux à celui d'hormone jouant un rôle crucial dans de nombreux mécanismes physiologiques et dont le déficit est impliqué dans plusieurs pathologies. Nous présentons, dans ce travail, l'expérience du laboratoire central de biochimie dans le dosage de la 25 OH vitamine D. Enquête descriptive exhaustive portant sur les dosages de la 25 OH vitamine D effectués chez 350 patients du Centre Hospitalier Ibn Sina (CHIS). La méthode adoptée est un dosage immunologique par chimiluminescence sur microparticules réalisés sur l'auto-analyseur ARCHITECT 8200 (ABBOTT®) pendant une période de six mois (du 01 Juin 2011 au 31 Decembre 2011). Quatre vingt et onze pourcent des patients présentent une hypovitaminose. En effet 76,6% des patients souffrent d'une insuffisance en vitamine D, 12,3% de carence vitaminique et 2,6% d'ostéomalacie. L'hypovitaminose est associée dans 92,18% des cas à une normocalcémie, dans 76,87% des cas à une Hyperparathormone, dans 92,81% à des troubles thyroïdiens et dans 97,5% à une insuffisance rénale. Par ailleurs aucune relation statistiquement significative n'est établie entre l'hypovitaminose et le diabète. A la lumière des implications des hypovitaminoses dans plusieurs pathologies ou dans leurs complications et au vu du nombre élevé de patients présentant un déficit en vitamine D, il paraît judicieux d'envisager une étude épidémiologique sur le statut en vitamine D dans la population marocaine comme outil préventif avant d'élargir le dosage de ce marqueur biologique en vue d'une éventuelle supplémentation.

    L'accouchement gémellaire différé définit un accouchement en deux ou plusieurs temps, avec l'expulsion spontanée d'un premier fœtus au deuxième ou au troisième trimestre, et un prolongement de la grossesse pour obtenir un accouchement du ou des fœtus restants en gestation le plus proche possible du terme. Cette technique est mise en œuvre, en cas de grossesse gémellaire pour prévenir la prématurité du fœtus restant après l'expulsion très prématurée d'un premier fœtus. Nous rapportons deux cas observés à la maternité du Centre Hospitalier de Creil avec des latences respectives de 3 et 52 jours pour lesquels nous discutons la prise en charge. PMID:25722777

    De plus en plus de patients diabétiques sont pris en charge en HDC. Les conséquences sont multiples, notamment les problèmes de pied diabétique qui demeurent mal connus du patient diabétique et des soignants ce qui retentit considérablement sur la qualité de prise en charge. Nous avons réalisé une Etude transversale en Novembre 2011 au centre d'hémodialyse de l'hôpital Al Farabi d'Oujda, incluant tous nos patients diabétiques HDC. Nous avons relevé les données démographiques, clinico-biologiques et dialytiques. Nous avons receuilli les éléments suivants: la présence ou non de douleur évalué par l’échelle visuelle analogique (EVA), le périmétre de marche, le recours ou non aux soins de pédicurie, le chaussage adapté, les antécédents de chirurgie vasculaire, l'existence ou non de troubles statiques et trophiques des pieds et la recherche d'une neuropathie par un test utilisant un brin de coton. L'analyse statistique est réalisée à l'aide du logiciel 11,5. Dans notre série, 12,9% des patients HDC sont diabétiques et présentent des troubles podologiques, aucun de nos patients n'a bénéficié de pontages ni angioplastie du membre inférieur alors que 8% ont subi des amputations. Le périmètre de marche est limité chez 75% des patients. 16,6% plaies diverses. Les diabétiques en HDC représentent une population de patients fragiles qui nécessitent une prise en charge multidisciplinaire visant d'abord la prévention, le diagnostic précoce des ulcérations du pied diabétique, le traitement adapté aussi bien de l'infection que de l’équilibre glycémique, de nombreuses amputations chez ces patients peuvent être évitées grâce à un suivi et un programme d’éducation thérapeutique adapté.

    L'infection urinaire chez l'insuffisant rénal est fréquente et particulière dans sa prise en charge diagnostique et thérapeutique. L'objectif de notre étude est de déterminer le profil bactériologique et d’étudier les facteurs de risque des infections urinaires chez le patient insuffisant rénal chronique en milieu de néphrologie. Etude prospective débutée en Septembre 2012 menée au service de néphrologie à l'hôpital régional d'Oujda de l'oriental Marocain. Ont été inclus tous les patients hospitalisés en néphrologie avec une infection urinaire documentée. Nous avons analysé les données démographiques, cliniques, biologiques, et thérapeutiques de nos patients à l'admission et au cours de leurs hospitalisations. 48 épisodes d'infections urinaires chez 43 patients ont été colligés dont 3 enfants. L'incidence de l'infection urinaire dans notre étude était de 4,65%. La médiane d’âge était de 53 (32-66) années. 60,4% étaient de sexe féminin. Le germe isolé était un Escheria Coli dans 58,3% et un Klebsiella dans 29,2%. Le germe isolé était résistant à l'amoxicilline-acide clavulanique dans 83% des cas. L'antibiotique prescris en premiére intention chez nos patients était une céphalosporine de 3 éme génération dans 50%. L’évolution chez nos patients était favorable dans 89,6% des cas. 33,3% avaient présenté un sepsis et on a noté le décès dans 10,4% des cas. Les infections urinaires chez l'insuffisant rénal chronique reste très grave vu leur lourde morbi-mortalié d'où l'intêrét d'un dépistage précoce chez cette population. Un usage raisonné des antibiotiques est nécessaire afin de prévenir l'extension des résistances bactériennes. PMID:26213601

  1. Cloning, purification, crystallization and X-ray crystallographic analysis of Ignicoccus hospitalis neelaredoxin

    International Nuclear Information System (INIS)

    Diffraction-quality crystals of I. hospitalis neelaredoxin have been produced. The cloning, expression, purification, crystallization and X-ray crystallographic analysis are reported. Superoxide reductases (SORs) are metalloproteins which constitute the most recently identified oxygen-detoxification system in anaerobic and microaerobic bacteria and archaea. SORs are involved in scavenging superoxide radicals from the cell by catalyzing the reduction of superoxide to hydrogen peroxide and are characterized by a catalytic nonhaem iron centre coordinated by four histidine ligands and one cysteine ligand. Ignicoccus hospitalis, a hyperthermophilic crenarchaeon, is known to have a neelaredoxin-type SOR that keeps toxic oxygen species levels under control. Blue crystals of recombinant I. hospitalis oxidized neelaredoxin (14.1 kDa, 124 residues) were obtained. These crystals diffracted to 2.4 Å resolution in-house at room temperature and belonged to the hexagonal space group P6222 or P6422, with unit-cell parameters a = b = 108, c = 64 Å. Cell-content analysis indicated the presence of one monomer in the asymmetric unit

    Full Text Available The CFD (computer fluid dynamic simulation of the complete engine cycle of the 2400 cm3 JTD 10 V engine for the Alfa Romeo 156 is presented. The intake stroke analysis has followed a procedure usually applied at CRF for gasoline engines. Spray and combustion analysis at the selected operating condition of 3500 tr/min and 13 bar BMEP (brake mean effective pressure has given results in fair agreement with the experimental data, but revealed the need of more accurate models for the initial phase of combustion. Finally, the simulation of the exhaust phase has required great care in the set-up of the initial field and boundary conditions. Flow field characteristics are discussed at two crank angles, corresponding to peak values of the exhaust mass flow rate. Cet article présente la simulation 3D du cycle complet du moteur 2400 cm3 JTD 10 V de l'Alfa Romeo 156. L'analyse de la phase d'admission a suivi une procédure habituellement utilisée pour les moteurs à essence. L'analyse du spray et de la combustion au régime choisi de 3500 tr/min et 13 bar de PMI se compare raisonnablement aux essais, mais indique qu'une meilleure description de la phase initiale de la combustion est nécessaire. La simulation de la phase d'échappement a requis une grande attention quant à la spécification du champ initial et des conditions aux limites. On étudie ici les caractéristiques de l'écoulement à deux instants de cycles correspondant à des maxima de débits à l'échappement.

    2016-05-14

    A quantum chemical study of H2 activation at fluorides of coinage metals, MF (M = Cu, Ag and Au), and its splitting was performed. The following reaction path was analyzed: FMH2→ FHHM → HMFH, where both the molecular complexes and the corresponding transition states have been characterized at the CCSD(T)/aug-cc-pVQZ//MP2/aug-cc-pVQZ level of theory. Further single-point CASSCF/CASPT2 calculations, including spin-orbit coupling effects, were also performed to analyze the role of non-dynamic correlation. The scalar relativistic effects are included via aug-cc-pVQZ-PP basis sets used for the metals. The dihydrogen-bonded copper (FHHCu) and silver (FHHAg) complexes are observed as a result of H2 cleavage, while the corresponding FHHAu gold complex is not found but the HAuHF arrangement is observed, instead. The energetic and geometrical parameters of the complexes have been analyzed and both the Quantum Theory of Atoms in Molecules approach and the Natural Bond Orbitals method were additionally applied to analyze the intermolecular interactions.

    L'objectif de ce travail était de décrire les caractéristiques épidémiologiques, cytologiques et immunophénotypiques des leucémies aigues (LA) chez les enfants diagnostiqués au Centre Hospitalo-universitaire (CHU) Ibn Sina et de déterminer aussi la concordance entre les résultats de la cytologie à ceux de l'immunophénotypage. Il s'agit d'une étude transversale réalisée au laboratoire d'hématologie du CHU Ibn Sina entre Juin 2012 et Mai 2014. Parmi 104 cas de LA diagnostiqués, 52% étaient des garçons avec un sex-ratio H/F= 1,32 et l’âge médian de 5,7 ans. La répartition des différents types de LA était: LA lymphoïde (LAL) (74%), LA myéloïde(LAM) (20,2%), LA biphénotypique(LAB) (65,8%). Parmi les LAL,78% ont été classé LAL B et 22% comme LALT. Les signes cliniques étaient principalement présentés par le syndrome tumoral (73,1%), la fièvre (61%) et syndrome hémorragique (50%). Les anomalies de l'hémogrammeles plus fréquents étaient: thrombopénie (89,4%), anémie (86,5%), hyperleucocytose (79,8%). Le taux des blastes périphérique et médullaires était statistiquement élevé pour LAL que pour LAM et LAB (p<0,001). Le taux de rechute et de mortalité était respectivement de 21,2% et16, 3%. Le taux de concordance entre les résultats de la cytologie et ceux de l'immunophénotypage était de 92,7% pour LAL et de 82,6% pour LAM. Le diagnostic des LA se base toujours en premier sur la cytologie. L'immunophénotypage nous a permis de faire une meilleure distinction entre les leucémies aiguës. La prise en charge des LA pédiatriques est un problème majeur qui nécessite les centres spécialisés. PMID:27516823

    Introduction La malnutrition constitue une toile de fond sur laquelle se greffent plusieurs infections. L'objectif de ce travail est de déterminer les infections les plus létales, la durée médiane de séjour et le gain pondéral médian journalier des enfants malnutris. Méthodes Étude de cohorte rétrospective des enfants malnutris de 0 à 59 mois hospitalisés au Centre Nutritionnel et Thérapeutique de Bukavu du 1er janvier 2011 au 31 décembre 2013. L’évaluation du risque de survenue de décès par complication infectieuse a été faite par la mesure du risque relatif. Nous avons utilisé le test de Mann-Whitney pour comparer les médianes. Les Odd ratio ajustés par régression logistique et leurs intervalles de confiance à 95% du risque de mortalité ont été donnés pour chaque cause infectieuse. Résultats Au total, 574 enfants avaient été inclus. Cinq cent vingt et un (90.8%) enfants étaient sortis guéris, 10 (1.7%) avaient abandonné le traitement et 43 (7.5%) étaient décédés. La durée médiane de séjour était de 19 (13-26) jours et le gain pondéral médian journalier était de 7 (3-13) g/kg/j. Il existait une association statistiquement significative entre la mortalité et le sepsis / choc septique (p = 0,0004), la méningite (p = 0,00001), et l'infection à VIH (p = 0,02). Conclusion Une meilleure prise en charge de la malnutrition aigüe dans notre région devrait se baser sur la mise en place des unités spécialisées et bien équipées pour la prise en charge de la malnutrition associées aux infections sévères.

  11. The Role of the African Union Pan African Veterinary Vaccine Centre (AU-PANVAC) in Rinderpest Eradication

    International Nuclear Information System (INIS)

    PANVAC originated in 1986 in response to the need for effective control of rinderpest in Africa. Earlier attempts to eradicate the disease through the multi-national JP15 had failed in the 1970s, partly because insufficient levels of immunity were sustained in vaccinated animals, owing to the use of vaccines that had not been certified by independent quality control. This failure prompted the then OAU (now the AU) to request FAO's assistance in setting up a system for independent quality control of the rinderpest vaccines used in the campaign. Initially, this was achieved through a short-term FAO TCP project in 1986, which established two regional vaccine quality control and training centres: one in Dakar (Senegal) for Central and Western Africa; and one in Debre Zeit (Ethiopia) for Eastern and Southern Africa (TCP/RAF/6767). These centres operated from 1989 to 1992 under a project funded by UNDP; in 1993, they were merged into PANVAC, hosted by the Ethiopian Government at the National Veterinary Institute (NVI), Debre Zeit. PANVAC's mandate was to perform quality control on priority vaccines (primarily rinderpest and contagious bovine pleuropneumonia), according to international standards; promote the adoption of biological standardization and control of veterinary vaccines in Africa, through establishment of a repository of characterized reference vaccine materials; develop internationally recognizable quality control criteria; and promote the principles of good manufacturing practice. PANVAC's contributions. PANVAC's greatest impact on the global rinderpest eradication campaign was in improving the quality of the rinderpest vaccine used in the field. A total of 193 batches of rinderpest vaccine from all the vaccine producing laboratories in Africa were tested between 1996 and 1998, and it was found that the strict, standardized quality control of rinderpest vaccines initiated by PANVAC had resulted in signifi- cant improvements in the quality of the vaccines

    Nanoarchaeum equitans and Ignicoccus hospitalis represent a unique, intimate association of two archaea. Both form a stable coculture which is mandatory for N. equitans but not for the host I. hospitalis. Here, we investigated interactions and mutual influence between these microorganisms. Fermentation studies revealed that during exponential growth only about 25% of I. hospitalis cells are occupied by N. equitans cells (one to three cells). The latter strongly proliferate in the stationary phase of I. hospitalis, until 80 to 90% of the I. hospitalis cells carry around 10 N. equitans cells. Furthermore, the expulsion of H2S, the major metabolic end product of I. hospitalis, by strong gas stripping yields huge amounts of free N. equitans cells. N. equitans had no influence on the doubling times, final cell concentrations, and growth temperature, pH, or salt concentration ranges or optima of I. hospitalis. However, isolation studies using optical tweezers revealed that infection with N. equitans inhibited the proliferation of individual I. hospitalis cells. This inhibition might be caused by deprivation of the host of cell components like amino acids, as demonstrated by 13C-labeling studies. The strong dependence of N. equitans on I. hospitalis was affirmed by live-dead staining and electron microscopic analyses, which indicated a tight physiological and structural connection between the two microorganisms. No alternative hosts, including other Ignicoccus species, were accepted by N. equitans. In summary, the data show a highly specialized association of N. equitans and I. hospitalis which so far cannot be assigned to a classical symbiosis, commensalism, or parasitism. PMID:18165302

    Introduction En vue d'améliorer la prise en charge des patients souffrant de neuropathie (NP) associées à l'infection HIV, nous avons essayé de déterminer le profil clinique des personnes souffrant de NP au cours du suivi thérapeutique de leur infection HIV. Méthodes Il s'agit d'une étude transversale (n= 101) menée au centre d'excellence depuis 1 an. Notre analyse est essentiellement clinique. Par un examen clinique minutieux, nous avons recherché tous les symptômes et signes cliniques des NP. Subjectivement, les douleurs dominent le tableau. Pour affiner leur diagnostic, nous avons utilisé l’échelle DN4 (Diagnostic des douleurs neuropathiques) et l’échelle EVA (Evaluation de la gravité des douleurs). Nous avons ensuite analysé nos données en fonction de certains autres facteurs épidémiologiques tels que le taux des CD4, le traitement anti-HIV etc. Résultats Les 101 patients représentent 3,12% de la cohorte générale; 53,3% des patients présentent une abolition des réflexes ostéotendineux des membres inférieurs; 77,89% présentent une hypoesthésie thermo algique en chaussette et en gants; 25% ont présenté une amyotrophie des membres inférieurs; 76,5% ont été soumis à un traitement antirétroviral contenant la stavudine; 11,7% ont pris la didanosine (DDI) et Abacavir (ABC). 84% ont une moyenne de CD4 de 292 cel/mm3. Conclusion La NP altère la qualité de vie de nos patients et diminue l'adhérence au traitement antirétroviral. Plusieurs facteurs sont incriminés dans la survenue de la NP, l'effet direct des antirétroviraux, l'effet inflammatoire dysimmunitaire, l'effet infectieux lié aux infections opportunistes. D'autres facteurs seront recherchés et analysés ultérieurement. PMID:26185582

    BACKGROUND: The relationship between the hyperthermophiles Ignicoccus hospitalis and Nanoarchaeum equitans is the only known example of a specific association between two species of Archaea. Little is known about the mechanisms that enable this relationship. RESULTS: We sequenced the complete genome of I. hospitalis and found it to be the smallest among independent, free-living organisms. A comparative genomic reconstruction suggests that the I. hospitalis lineage has lost most of the genes associated with a heterotrophic metabolism that is characteristic of most of the Crenarchaeota. A streamlined genome is also suggested by a low frequency of paralogs and fragmentation of many operons. However, this process appears to be partially balanced by lateral gene transfer from archaeal and bacterial sources. CONCLUSIONS: A combination of genomic and cellular features suggests highly efficient adaptation to the low energy yield of sulfur-hydrogen respiration and efficient inorganic carbon and nitrogen assimilation. Evidence of lateral gene exchange between N. equitans and I. hospitalis indicates that the relationship has impacted both genomes. This association is the simplest symbiotic system known to date and a unique model for studying mechanisms of interspecific relationships at the genomic and metabolic levels.

    From the checking of 2750 index cards of hazards, the study relates the distribution of the chemical hazards in the Centre d'Etudes Nucleaires of Fontenay-aux-Roses. Those concerning the greatest number of agents in the Centre are classified according to the categories corresponding to the different conditions of working. Thus, the most important are put forward. Then, the authors rapidly make a review of hazards which may have some special interest because they appear more specific of the nuclear energy or because they are the most frequently noted on the index cards of hazards. The case of the tributylphosphate is studied more precisely.

    There are at least two reasons for undertaking a study of the political economy of India's electrical sector. Given that it is placed under the joint responsibility of the Centre and the States, its evolution reflects the relations between these two levels of the Indian federal system. Besides, the recent implementation of guidelines which have found favour with a large number of foreign countries could camouflage a subtle relationship with globalization which, in the case of India, is determined largely by the power equations within the country. Indeed, the reform path chosen integrates two elements: the argument that reforms have become necessary on account of the inefficiency of public sector organisations whose modes of functioning are inherited from the Indian bureaucratic system; secondly, there are political and economic forces who demand reforms as an essential element of their political strategy. In particular, contrary to the classical view in India that with liberalization there has been an emancipation of the States with regard to the Centre and the creation of expanding markets for foreign investments, the 'globalization' of the electricity sector, understood here as the opening up to the foreign private sector, could in reality be equated to a relative strengthening of the Centre vis-a-vis the States. It could also turn out to be to the advantage of some very local components, such as consumers' associations, whether rural or of local communities. (author)

  8. Les traductions russes de La Légende de Saint Julien L’Hospitalier

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available Les œuvres de Gustave Flaubert étaient et restent toujours populaires auprès du lectorat russe. La Légende de Saint Julien l’Hospitalier, parue en 1876, a suscité l’intérêt d’un grand nombre de traducteurs. Ivan Turgenev fut le premier à réaliser une traduction officielle en russe de la Légende en 1877. Par la suite, d’autres versions ont suivi. Cet article propose l’analyse de trois traductions réalisées à trois périodes différentes par trois grandes personnalités de la littérature russe, Ivan Turgenev, Alexandr Blok et Maximilian Vološin. Chacun d’eux a sa propre méthode de traduction, utilise ses propres procédés afin de restituer au mieux l’effet de stylisation créé par Gustave Flaubert. La distance temporelle qui existe entre les trois traductions suppose que chacune d’elles suive les tendances littéraires propres à son époque. Ainsi, l’analyse comparative des traductions sera menée sous un angle diachronique. Par ailleurs, la traduction de chacun d’eux reflète les tendances dominantes dans le développement des différentes conceptions du métier du traducteur et plus particulièrement sur le travail de stylisation historique.The Russian reader has always been lost in admiration at Gustave Flaubert’s production, which is particularly style-worked and of a high literary quality. The Legend of St. Julian the Hospitaller, wrote in 1876, is marked out by stylistic treasures where the form is also important as the content. Consequently, this text represents a difficult translation exercise. However, the text has always aroused interest of translators. It was in the year 1877 that Ivan Turgenev first translated it into Russian and after that various versions with distinctive features have been turning up. This paper consists on examining three versions carried out for the three different periods by three eminent personalities of the Russian literature, Ivan Turgenev, Alexandr Blok, Maximilian

    2010-09-15

    By its omnipresence in society, the energy question is at the heart of sustainable development issues. The engineer, as a central actor of human society development, is therefore tightly linked to the energy issue and he must actively contribute to resolve it by integrating to his practices the principles of sustainable development and by applying the solutions that arises. Part of these elements include as the main ones, listening to the consideration of citizens, becoming aware of the environment importance and reducing costs at all levels. The engineer is a social actor that cannot be ignored in the resolution of these issues. [French] Par son omnipresence dans la societe, la question energetique est au coeur des enjeux du developpement durable. L'ingenieur, etant un acteur central du developpement des societes humaines, est donc inextricablement lie a la question energetique qu'il doit contribuer activement a resoudre en integrant a sa pratique les principes du developpement durable et en appliquant les solutions qui en decoulent. Parmi ces elements, l'ecoute des considerations citoyennes, la prise de conscience de l'importance de l'environnement et la reduction des couts a tous les niveaux sont des elements centraux.

    Introduction L'infection par Helicobacter pylori constitue un problème de santé publique notamment dans les pays en développement. Elle entraine une gastrite pouvant évoluer vers des formes sévères d'ulcération et de transformation maligne. La présenté étude avait pour objectif de diagnostiquer H. pylori par des techniques sérologique et moléculaire au Burkina Faso. Méthodes L’étude prospective a été conduite de mars à juin 2012 sur 70 patients venus en consultation dans le service de gastroentérologie au Centre Médical Saint Camille. Le diagnostic de H. pylori a été réalisé par le test ELISA Immunocomb (ORGENICS Ltd, Yavne, Israël) et la PCR sur des biopsies gastriques prélevées sur les patients. Résultats Les pathologies gastroduodénales étaient plus fréquentes chez les patients de plus de 45 ans. Les prévalences de H. pylori étaient respectivement de 88,57% et de 91,43% par sérologie Immunocomb et par PCR. La différence entre les deux techniques n’était pas significative (P = 0,573). La performance de la PCR a été comparée à celle de la technique Immunocomb. Les résultats montrent une sensibilité et une spécificité de 92,2% et 50,0% pour la technique Immunocomb. Conclusion Le diagnostic de H. pylori par PCR est plus spécifique que le test sérologique Immunocomb et devrait être introduit dans le diagnostic de routine de cette bactérie pathogène au Burkina Faso.

    Nous rapportons deux cas d'infection à Pseudomonas aeruginosa: un cas de méningite et un cas d'infection urinaire. Les auteurs rappellent qu’à côté des étiologies classiques des méningites et des infections urinaires, des germes résistants comme Pseudomonas aeruginosa peuvent être responsables d'infections à localisation méningées et urinaires et dont il faut connaître pour une bonne prise en charge. Le traitement de ces infections requiert un antibiogramme au regard de la grande capacité de résistance de Pseudomonas aeruginosa en milieu hospitalier. La limitation des gestes invasifs et l'application rigoureuse des mesures de prévention des infections en milieu hospitalier contribueront à lutter efficacement contre ces infections en milieu de soins.

  8. Dosimeter calibration facilities and methods at the Radiation Measurement Laboratory of the Centre d'etudes nucleaires, Grenoble

    International Nuclear Information System (INIS)

    At the Centre d'etudes nucleaires, Grenoble, the Radiation Measurement Laboratory, which forms part of the Environmental Protection and Research Department, serves the entire Centre for purposes of dosimetry and the calibration of dose meters. The needs of radiation protection are such that one must have facilities for checking periodically the calibration of radiation-monitoring instruments and developing special dosimetry techniques. It was thought a good idea to arrange for the dosimetry and radiation protection team to assist other groups working at the Centre - in particular, the staff of the biology and radiobiology laboratories - and also bodies outside the framework of the French Commissariat a l'energie atomique. Thus, technical collaboration has been established with, for example, Grenoble's Centre hospitalier universitaire (university clinic), which makes use of the facilities and skills available at the Radiation Measurement Laboratory for solving special dosimetry problems. With the Laboratory's facilities it is possible to calibrate dose meters for gamma, beta and neutron measurements

    La fièvre bilieuse hémoglobinurique (FBH) est une forme grave du paludisme; caractérisée par la survenue d'une hémolyse intravasculaire aiguë se traduisant par une anémie hémolytique, une insuffisance rénale aiguë et une hypovolémie. Son diagnostic repose essentiellement sur la clinique notamment la couleur des urines d'aspect rouge porto. Nous rapportons un cas de fièvre bilieuse hémoglobinurique chez un jeune garçon de 10 ans originaire et vivant dans une zone d'endémie palustre, colligé dans un CHU de Dakar (Sénégal). V.G est un garçon de 10 ans qui était hospitalisé pendant 2 jours au service des urgences dans un centre de santé de proximité pour une fièvre associée à des vomissements qui évoluaient depuis 3 jours. Le test de diagnostic rapide (TDR) au paludisme était positif à la présence d'antigènes de Plasmodium falciparum dans le sang. Un traitement à base de quinine injectable (25 mg/kg/j), a été entrepris pendant 03 jours. Au quatrième jour, sont apparues une hémolyse intravasculaire aiguë et une hémoglobinurie avec une insuffisance rénale aiguë anurique. La goutte épaisse était revenue négative et le traitement par la quinine injectable arrêté. Le relais a été fait avec les dérivés de l'artémisinine. Trois (03) séances d'hémodialyse ont été réalisées. L’évolution était favorable, par la reprise de la diurèse et la normalisation de la fonction rénale. La FBH existe encore dans notre pratique quotidienne.

    The author presents considerations which should prove to be of interest to all those who have to design, to construct and to operate a nuclear research centre. A large number of the ideas presented can also be applied to non-nuclear scientific research centres. In his report the author reviews: various problems with which the constructor is faced: ground-plan, infrastructure, buildings and the large units of scientific equipment in the centre, and those problems facing the director: maintenance, production, supplies, security. The author stresses the relationship which ought to exist between the research workers and the management. With this aim in view he proposes the creation of National School for Administration in Research which would train administrative executives for public or private organisations; they would be specialised in the fields of fundamental or applied research. (author) [French] L'auteur propose une base de reflexions a tous ceux qui doivent concevoir, realiser et faire vivre un Centre d'Etudes Nucleaires. Un grand nombre des idees exprimees peut d'ailleurs s'appliquer a un Centre d'Etudes Scientifiques non nucleaires. Dans son ouvrage, l'auteur passe en revue les differents problemes qui se posent au constructeur: plan, masse, infrastructure, batiments et grands appareils du Centre, et ceux qu'a a resoudre le directeur: entretien, fabrication, approvisionnements, securite. L'auteur insiste sur l'aspect des rapports qui doivent exister entre les chercheurs et ceux qui les administrent. Il propose a cette fin la creation d'une Ecole Nationale d'Administration de la Recherche qui formerait des cadres administratifs pour les organismes publics ou prives, specialises dans la Recherche fondamentale ou appliquee.

To this end, INIBAP established a Transit Centre (ITC at the Laboratory of Tropical Crop Improvement of K.U.Leuven in Belgium, a non banana producing country. Plant material from all over the world is deposited at ITC. This global collection of banana and plantain germplasm, comprising approximately 1 100 accessions, is held under the auspices of FAO. The in vitro active collection is stored under slow growth conditions (low illumination and reduced temperature. In order to safeguard the material for the long terni, cryopreservation protocole for banana meristems have been developed. Samples of virus-tested clones are available freely and at no cost from the ITC gene batik on request. Since 1985, over 5 000 samples of accessions have been distributed worldwide to interested parties for specific research, breeding and evaluation, and production. A major constraint for the efficient use of the Musa collection is the limited information available on the genetic resources maintained. Through INIBAP's Musa Germplasm Information System (MGIS, passport, characterization and evaluation data on existing collections worldwide are being assembled to enhance the knowledge on Musa diversity, rationalize conservation and improve the use by curators, breeders and scientiste

    The H.E.S.S. experiment (High Energy Stereoscopic System) consists of four imaging atmospheric Cherenkov telescopes to study the southern astrophysical sources above 100 GeV. This thesis presents the detector as well as the analysis chain. The calibration methods are described in details and the systematic errors on the image amplitude are derived. Then, an analysis based on a semi-analytical model of the electromagnetic shower development in the atmosphere is presented. Tools to reconstruct the energy spectrum and the morphology of the very high energy {gamma}-ray sources are presented and applied to the Crab Nebula. Systematic errors associated to the spectrum analysis are estimated. All these techniques were applied to study the Galactic Centre emission above 100 GeV. The nature of the source detected in 2003 and 2004 observations is still unknown and its spectrum, variability and morphology are studied. Various candidates are proposed, among them the supermassive black hole Sgr A* located at the dynamical centre of the Milky Way, the supernova remnant Sgr A Est or interactions of accelerated particles with the dense medium of this region. In this thesis, the signal was interpreted in terms of dark matter annihilation (neutralinos or Kaluza-Klein bosons) in a dense halo located at the Galactic Centre. This analysis showed that, in the framework of these models, dark matter annihilation alone can not explain the H.E.S.S. signal. The main component would thus come from astrophysical sources.

    Full Text Available Combined Effect of Thitonia diversifolia Leaves and Inorganic Fertlizers on Maize Grain Yield and Soil Properties of a Central Cameroon Acrisol. Properties of a Central Cameroon Acrisol A study was conducted on an Acrisol in Centre Cameroon in order to evaluate the combined effects of Tithonia diversifolia (FTd and inorganic fertilizers (NPK and Urea on maize grain yields and soil properties. The experimental design was a randomized completed block design with three replications and six treatments: T0 (0FTd, 0NPK and 0 Urea; T1 (0FTd, 150 kg 20-10-10 and 150 kg of Urea/ha; T2 (0FTd, 75 kg 20-10-10 and 75 kg of Urea/ha; T3 (2.5 t/ha FTd, 0NPK and 0 Urea; T4 (5 t/ha FTd, 0NPK and 0 Urea; T5 (2.5 t/ha FTd, 75 kg 20-10-10 and 75 kg of Urea. Soil and Tithonia samples were collected and analyzed for nutrients contents. Tithonia leaves (FTd were incorporated into the soil two weeks before maize sowing. Physico-chemical laboratory analyses were carried out on soil samples and Tithonia leaves. Highly significant differences (p= 0.006 and p< 0.000 respectively were observed between treatments in the first and second cropping season for maize grain yields which varied between 1.8 to 6.4 t.ha-1; with the highest values obtained in T4 and T5 and the lowest in T0. The general trend of productivity was ranked as: T5=T4 >T1>T3>T2>T0. No significant difference was observed for all the soil properties tested. However, in the general trend, most soil properties tended to increase at the end of the experiment, excepted sand content, pH and available phosphorus. With the acceptability index (IA of more than 2 in T4 (2.65 and T5 (2.53, the study has shown that Tithonia diversifolia has a potential for improving plant nutrient availability in these soils for the cultivation of maize without chemical fertilizers.

    Besides the very high activity liquids containing fission products, the chemical treatment of irradiated fuels produces a large volume of aqueous effluents and solid waste of relatively low radioactivity. These weakly active products can be eliminated in the ground, in a hydrographic land system or in the sea. Techniques of evaporation, of resin concentration, and of coprecipitation give rise to inorganic sludges with a high water content. All these residues occupy a large volume and represent a far from negligible weight. In the case of the sludge, their relative fluidity necessitates a conditioning guaranteeing safe storage. The solution to the problem will consist in passing directly from a liquid or a suspension, to a solid whose structure is homogeneous and whose matter is inert with respect to the storage medium (soil, sea, etc. ). We have proposed to coat the radioactive products with bitumen. This article is designed to give a review of the studies undertaken on this method. It consists of a progress report rather than a final assessment. (authors) [French] En dehors des liquides de tres haute activite contenant des produits de fission, le traitement chimique des combustibles irradies produit un volume important d'effluents aqueux et de residus solides de radioactivite relativement faible. Ces produits, faiblement actifs, peuvent etre elimines dans le sol, dans un systeme hydrographique terrestre ou dans la mer. Les techniques d'evaporation, de concentration sur resine, de coprecipitation, permettent la decontamination prealable des liquides. La coprecipitation donne naissance a des boues minerales dont la teneur en eau est elevee. Tous ces residus occupent un volume important et representent un poids non negligeable. Dans le cas des boues, leur fluidite relative exige un conditionnement donnant toutes garanties de securite au stockage. La solution du probleme consistera a passer directement d'un liquide ou d'une suspension a un solide

    The use of 14 MeV neutron irradiation makes it possible to extend the field of application of activation analysis to elements which cannot be activated in nuclear reactors (oxygen, boron, for example) or else to consider the possibility of 'portable' measurement units for routine analyses. With this aim, tests have been carried out for studying the sensitivity and interferences in the case of the dosing of oxygen in eleven different matrices using 150 and 300 kV SAMES accelerators producing 14 MeV neutrons by the reaction {sup 3}H (d, n) {sup 4}He. The sensitivity of the dosage methods for six writer elements has also been studied. The results obtained show that, for a neutron flux of 10{sup 10} n/4{pi}, the sensitivities vary from 100 {mu}g and 1 mg for oxygen in nine matrices (Be, Ta, Nb, Ti, Zr, Fe, Al, Sb, Si) and that it is possible to dose the six elements F, B, Y, Si, N, Al with sensitivities of between 1 an 1000 micrograms. (authors) [French] L'irradiation au moyen de neutrons de 14 MeV permet d'etendre le domaine d'application de l'analyse par activation a des elements non activables en reacteur nucleaire (oxygene, bore, par exemple) ou encore d'envisager des unites de dosage ''portables'' pour des analyses de routine. Dans ce but, des essais ont ete effectues pour etudier les sensibilites et les interferences dans le cas du dosage de l'oxygene dans onze matrices differentes, au moyen d'accelerateurs SAMES 150 et 300 kV. produisant les neutrons de 14 MeV par la reaction {sup 3}H (d, n) {sup 4}He.

    Introduction Le but de cette étude était de déterminer la fréquence de la tuberculose (TB) chez le personnel de santé du secteur public en charge des patients tuberculeux et d’évaluer les facteurs de risque de contracter la tuberculose chez ce personnel au Burundi. Méthodes Il s’agit d’une étude transversale à visée analytique réalisée auprès de 300 travailleurs prestant dans 30 centres de dépistage et de traitement de la TB (CDT) au Burundi du 16 octobre au 15 novembre 2012. Les paramètres sociodémographiques et professionnels ainsi que l’antécédent de vaccination BCG de travailleurs ayant été touché par la TB ont été analysé et comparé à ceux de travailleurs qui ne l’ont pas été. Le seuil de signification a été fixé à p risque de souffrir de la TB est de près de 4 fois chez les travailleurs âgés d’au moins 50 ans (OR=3,73; 1,53-9,08), chez ceux qui n’ont jamais reçu de vaccin de BCG (OR=3,73; 1,24-11,03), chez ceux qui n’ont pas de cicatrice vaccinale de BCG (OR=3,80; 1,67-8,62) et chez ceux qui travaillent depuis au moins 6 ans dans un CDT (OR=3,79; 1,44-9,96); ce risque est de 9 fois chez ceux qui sont mariés (OR=9,42; 1,26-70,23), de 8 fois chez ceux qui n’aèrent pas leurs salles de travail (OR=8,20; 1,48-48,23) et de 6 fois chez ceux qui ont comme profession nettoyeur ou aide-soignant (OR=6,12; 2,92-12,82). Par contre, aucune corrélation statistiquement significative n’a été observée entre le fait de souffrir de la TB et le sexe mais aussi le nombre d’heures de contact d’un travailleur avec un patient tuberculeux (p>0,05). Conclusion L’âge, l’antécédent de vaccination de BCG ainsi que la majorité de paramètres professionnels sont en association avec la maladie TB des travailleurs de CDT. D’où, la maîtrise de certains facteurs de risque s’avère important pour faire face au fardeau de la TB parmi le personnel hospitalier. PMID:24847402

    L’épidémie du Virus de l'Immunodéficience Humaine en milieu pédiatrique est surtout le résultat de la transmission mère-enfant. Notre étude a pour objectif de décrire l'efficacité de la prévention de la transmission mère-enfant du Virus de l'Immunodéficience Humaine par le protocole OMS 2010 (Option A et trithérapie) au centre médical saint Camille de Ouagadougou. Nous avons mené une étude d'une cohorte d'enfants suivis dans le cadre de la prévention de la transmission mère-enfant du Virus de l'Immunodéficience Humaine au centre médical saint Camille de Ouagadougou sur une période de 2 ans allant du 1er Janvier 2012 au 31 Décembre 2013. Nous avons obtenu l'accord de 4900 femmes enceintes pour le dépistage de l'infection du Virus de l'Immunodéficience Humaine et 238 gestantes ont été diagnostiquées séropositives soit 4,86% de séroprévalence. Les femmes étaient surtout infectées par le Virus de l'Immunodéficience Humaine avec de type I (95,38%)). La majorité était sous trithérapie (74,3%) et (25,7%) sous prophylaxie (option A). Les nouveau-nés (92,5%) ont reçu un traitement antirétroviral à base de névirapine dans les 72 heures après la naissance. L'allaitement sécurisé a été appliquée dans 78% des cas. Le taux global de transmission mère-enfant du VIH était de 3,6% avec 3% de transmission chez les enfants nés de mères sous trithérapie antirétrovirale et 6,3% dans les cas de prophylaxie antirétrovirale. Le facteur de risque de transmission a été le long délai du début d'administration des antirétroviraux chez le nouveau-né. La mortalité infantile à un an était de 3,5%. Cette étude a révélé l'efficacité de l'Option A et conforté celle de la trithérapie, le passage à l'Option B+ serait donc plus bénéfique. PMID:26966499

    Retrospective analysis of the treatment of choroidal melanoma with proton-therapy at the Centre de protontherapie d`Orsay, France. Between September 1991 and September 1995, 612 patients presenting with choroidal melanoma were treated by proton-therapy in Orsay. Following initial management of the first 464 patients, results were analyzed, as were results after a 1-year follow up for 305 patients, a 2-year follow-up for 169 patients, and a 3-year follow-up for 59 patients. Univariate analysis showed that the actuarial local recurrence rate was 5 %, the 3-year survival rate 88 %, and the overall metastatic rate 5%. The initial tumor volume was the most significant predictive factor for visual results and metastases. Multivariate analysis revealed that visual results were significantly related to the initial tumor volume, initial retinal detachment, and total dose delivered to the optic nerve and macula. Proton-therapy of choroidal melanoma allows in most cases conservation of the eye without modification of survival. Visual results mainly depend on the site and size of the tumor. (author) 16 refs.

    The evolution of charged-particle production in collisions of heavy ions at relativistic energies is investigated as function of centrality in a nonequilibrium-statistical framework. Precise agreement with recent d + Au and Au + Au data at sqrt(s_NN) = 200 GeV is found in a Relativistic Diffusion Model with three sources for particle production. Only the midrapidity source comes very close to local equilibrium, whereas the analyses of the overall pseudorapidity distributions show that the systems remain far from statistical equilibrium.

  8. The ideal Atomic Centre

    International Nuclear Information System (INIS)

    The author presents considerations which should prove to be of interest to all those who have to design, to construct and to operate a nuclear research centre. A large number of the ideas presented can also be applied to non-nuclear scientific research centres. In his report the author reviews: various problems with which the constructor is faced: ground-plan, infrastructure, buildings and the large units of scientific equipment in the centre, and those problems facing the director: maintenance, production, supplies, security. The author stresses the relationship which ought to exist between the research workers and the management. With this aim in view he proposes the creation of National School for Administration in Research which would train administrative executives for public or private organisations; they would be specialised in the fields of fundamental or applied research.

  10. International research centre launched

    International Nuclear Information System (INIS)

    Full text: The first scientific research and educational institution to be set up on a completely international basis was officially inaugurated in Trieste on 5 October 1964 by the Director General of IAEA, Dr. Sigvard Eklund, when he opened the first seminar of the International Centre for Theoretical Physics. As evidence of the international nature of the institution he noted that the scientists who would work and teach there during the first year represented sixteen different countries. By the end of 1964, the Centre building was nearing completion and three of the five floors were occupied. A successful symposium had been held on the subject of plasma physics, and a score of professors and fellows were at work, from Bulgaria, Czechoslovakia, Greece, India, Japan, Jordan, the Netherlands, Norway, Pakistan, Poland, the United Kingdom, and the United States. A dozen scientific papers had been issued as preprints. The main purpose of the Centre is to foster the advancement of theoretical physics through training and research; at first the chief subject will be high-energy and elementary particle physics. Plasma physics, low energy physics and solid-state physics will also be dealt with. Special attention is paid to the needs of the developing countries. Of the 25 fellows selected for the academic year 1964-65, more than half are from South America, Africa and Asia. In conjunction with the Research Centre, there is an Advanced School for theoretical Physics to provide graduate training for fellows who need such preparation before they embark upon research. The Centre works under the guidance of a Scientific Council comprising the president, Prof. M. Sandoval-Vallarta (Nuclear Energy Commission of Mexico); Prof. A. Abragam (Saclay, France); Prof. R. Oppenheimer (Institute for Advanced Study, Princeton, USA); Dr. V. Soloviev (Dubna, USSR); Prof V.F. Weiskopf (Director General, CERN) ; Prof Abdus Salam (Imperial College, London) ; Prof. P.

  11. Advanced CANDU control centre

    International Nuclear Information System (INIS)

    The CANDU 9 design is based upon the 900 MWe class Darlington station in Canada, which is among the world leading nuclear power stations for capacity factor with low operation, maintenance and administration costs. The CANDU 9 design provides an advanced control centre with enhanced operations features. The advanced AECL control centre design includes the proven functionality of existing CANDU control centres, those implementable characteristics identified by systematic design combined with a human factors analysis of operations requirements and features needed to improve station operability which are made possible by the application of current technology. The design strategy is to preserve the general main control room operations staff work area as unchanged as possible to facilitate the inclusion of past features and operational experience while incorporating operability improvements. The author will present those features of the advanced CANDU control centre which facilitates improved operability capabilities. As well, aspects of the design process utilized, application of simulation technology and conclusions regarding this design approach will be reviewed

    Full Text Available Le problème de pénurie de main-d’œuvre dans les centres hospitaliers québécois exige de repenser l’organisation du travail dans le respect du droit de retrait préventif de la travailleuse enceinte. Le recours au droit de retrait préventif offre l’occasion de questionner et de transformer, avec la participation de chacune des parties concernées, les façons de faire qui n’offrent pas une efficacité suffisante sur le plan de la santé et sécurité, de la gestion du personnel et de la production. Un nouveau modèle émerge en ce sens. À partir des résultats d’une recherche effectuée dans le secteur hospitalier de trois régions du Québec, l’article fait ressortir comment l’ajout d’une ressource en prévention, dédiée à l’application du droit de retrait préventif et de son intégration dans un plan d’intervention global en santé au travail, permet d’agir efficacement sur les contraintes ergonomiques et organisationnelles et favorise le maintien en emploi durant la grossesse avec une approche constructive et bénéfique pour les travailleuses et pour l’employeur.The workforce shortage problem in Quebec’s hospitals requires that the re-assignment rights of pregnant workers be respected when reconsidering work organization. The right to re-assignment provides an opportunity to question and improve – with the participation of the involved parties – the efficiency of approaches and methods regarding health and safety, production, and staff management. A new model is emerging as a result. Beginning with results from research carried out in hospitals from three Quebec regions, this paper shows how adding a prevention agent who is in charge of applying re-assignment rights makes it possible to effectively influence ergonomic and organizational constraints and to keep women working during pregnancy with a constructive approach that is beneficial for both workers and employers.La escasez de mano de obra en los

    The demand for elderly centre has increased tremendously abreast with the world demographic change as the number of senior citizens rose in the 21st century. This has become one of the most crucial problems of today's era. As the world progress into modernity, more and more people are occupied with daily work causing the senior citizens to lose the care that they actually need. This paper seeks to elucidate the best possible design of an elderly care centre with new approach in order to provide the best service for them by analysing their needs and suitable activities that could elevate their quality of life. All these findings will then be incorporated into design solutions so as to enhance the living environment for the elderly especially in Malaysian context.

    In this talk I will review PHOBOS data on charged particle multiplicities, obtained in Au+Au and d+Au collisions at RHIC. The general features of the Au+Au pseudorapidity distributions results will be discussed and compared to those of /line{p}p collisions. The total charged particle multiplicity, scaled by the number of participant pairs, is observed to be about 40% higher in Au+Au collisions than in /line{p}p and d+Au systems, but, surprisingly at the same level of e+e- collisions. Limiting fragmentation scaling is seen to be obeyed in Au+Au collisions.

For the research with synchrotron light major new facilities are operated and built (FLASH, PETRA-III, and XFEL). DESY furthermore acts as Data-Tier1 centre for the Neutrino detector IceCube. Established within the EGI-project DESY operates a grid infrastructure which supports a number of virtual Organizations (VO), incl. ATLAS, CMS, and LHCb. Furthermore, DESY hosts some of HEP and non-HEP VOs, such as the HERA experiments and ILC as well as photon science communities. The support of the new astroparticle physics VOs IceCube and CTA is currently set up. As the global structure of the grid offers huge resources which are perfect for batch-like computing, DESY has set up the National Analysis Facility (NAF) which complements the grid to allow German HEP users for efficient data analysis. The grid infrastructure and the NAF use the same physics data which is distributed via the grid. We call the conjunction of grid and NAF the DESY Grid Centre. In the contribution to CHEP2012 we will in depth discuss the conceptional and operational aspects of our multi-VO and multi-community Grid Centre and present the system setup. We will in particular focus on the interplay of Grid and NAF and present experiences of the operations.

We also find event shapes to be close to spherical in the most central collisions, independent of bombarding energy and fragment mass up to 4He

  11. Growth and structure of Co/Au magnetic thin films

    International Nuclear Information System (INIS)

    We have studied the growth and the crystallographic structure of magnetic ultra thin cobalt/gold films (Co/Au), in order to investigate the correlations between their magnetic and structural properties. Room temperature (R.T.) Co growth on Au (111) proceeds in three stages. Up to 2 Co monolayers (ML), a bilayer island growth mode is observed. Between 2 and 5 ML, coalescence of the islands occurs, covering the substrate surface and a Co/Au mixing is observed resulting from the de-construction of the Herringbone reconstruction. Finally, beyond 5 ML, the CoAu mixing is buried and the Co growth continues in a 3-D growth. Annealing studies at 600 K on this system show a smoothing effect of the Co film, and at the same time, segregation of Au atoms. The quality of the Co/Au interface (sharpness) is not enhanced by the annealing. The local order was studied by SEXAFS and the long range order by GIXRD showing that the Co film has a hexagonal close packed structure, with an easy magnetization axis perpendicular to the surface. From a local order point of view, the Co grows with an incoherent epitaxy and keeps its own bulk parameters. The GIXRD analysis shows a residual strain in the Co film of 4%. The difference observed between the local order analysis and the long range order results is explained in terms of the low dimensions of the diffracting domains. The evolution of film strains, as a function of the Co coverage, shows a marked deviation from the elastic strain theory. Modification of the strain field in the Co film as a function of the Au coverage is studied by GIXRD analysis. The Au growth study, at R.T., shows no evidence of a Au/Co mixing in the case of the Au/Co interface. The Au overlayer adopts a twinned face centred cubic structure on the rough Co film surface.

  12. The formation mechanism and the binding energy of the body-centred regular tetrahedral structure of He+5

    We propose the formation mechanism of the body-centred regular tetrahedral structure of the He+5 cluster. The total energy curve for this structure has been calculated by using a modified arrangement channel quantum mechanics method. The result shows that a minimal energy of -13.9106 a.u. occurs at a separation of 1.14a0 between the nucleus at the centre and nuclei at the apexes. Therefore we obtain the binding energy of 0.5202 a.u. for this structure. This means that the He+5 cluster may be stable with a high binding energy in a body-centred regular tetrahedral structure.

    The central attributes of primary care are: first contact (accessibility), longitudinality (person- focused preventive and curative care overtime), patient-oriented comprehensiveness and coordination (including navigation towards secondary and tertiary care). Besides taking care of the needs of the individuals, primary health care teams are also looking at the community, especially when addressing social determinants of health. The rationale for the benefits for primary care for health has been found in: 1) greater access to needed services; 2) better quality of care; 3) a greater focus on prevention; 4) early management of health problems; 5) organizing and delivering high quality care for chronic non-communicable diseases. This paper describes the role of primary healthcare centres in strengthening community primary services and in reducing health inequalities. Furthemore, the experiences of Regional Health Services from Tuscany and Emilia-Romagna are discussed, with a brief overview of the literature. PMID:24770539

  10. Hole centres in magnesium oxide

    International Nuclear Information System (INIS)

    When magnesium oxide crystals are exposed to ionizing radiation the electron-loss (hole) centres are normally identified as O·- ions. In this paper, I examine the EPR evidence for this, and compare the data with those for the hole centres in alkali- halides (VK centres). The latter are clearly σ* radical anions, such as F.-F-.The analogous centre in MgO is O.-O3-, which does not seem to have been considered. The results compare well, suggesting that the O·- centres are really O.-O3- radicals. In particular, the 17O data for the oxygen centre and the 19F data for F2·- give similar estimates of the 2s and 2p character of the orbitals on oxygen and fluorine, suggesting that the spin-density on oxygen is ca. 50%. The exception is the direction of the principal axes of these centres, which are quite different from each other. It is suggested that the primary hole-centres in MgO migrate by electron transfer to neighbouring cation vacancies where they are stable, and that at these sites the (1, 0, 0) directions are most favourable for σ- bonding

    2010-05-01

    The CMCC Data Distribution Centre (DDC) is the primary entry point (web gateway) to the CMCC. It is a Data Grid Portal providing a ubiquitous and pervasive way to ease data publishing, climate metadata search, datasets discovery, metadata annotation, data access, data aggregation, sub-setting, etc. The grid portal security model includes the use of HTTPS protocol for secure communication with the client (based on X509v3 certificates that must be loaded into the browser) and secure cookies to establish and maintain user sessions. The CMCC DDC is now in a pre-production phase and it is currently used only by internal users (CMCC researchers and climate scientists). The most important component already available in the CMCC DDC is the Search Engine which allows users to perform, through web interfaces, distributed search and discovery activities by introducing one or more of the following search criteria: horizontal extent (which can be specified by interacting with a geographic map), vertical extent, temporal extent, keywords, topics, creation date, etc. By means of this page the user submits the first step of the query process on the metadata DB, then, she can choose one or more datasets retrieving and displaying the complete XML metadata description (from the browser). This way, the second step of the query process is carried out by accessing to a specific XML document of the metadata DB. Finally, through the web interface, the user can access to and download (partially or totally) the data stored on the storage device accessing to OPeNDAP servers and to other available grid storage interfaces. Requests concerning datasets stored in deep storage will be served asynchronously.

  12. Prominent transverse flow of clusters in stopped Au(150AMeV)+Au reactions

    International Nuclear Information System (INIS)

    Stopped Au(150AMeV)+Au collisions have been measured with the FOPI-Detector at GSI by imposing an upper limit on the ratio of the global longitudinal momentum to the collected charge within an event. The ejectiles, in particular those with Z>3, have a rapidity close to mid-rapidity and exhibit angular distributions in the centre-of-mass strongly peaking around 90 thus suggesting an enhancement of the flow in the transverse direction. Fits to the data and comparisons with QMD calculations indicate an averaged collective velocity in the transverse direction equal to 0.12c. Significance of the determined velocity and temperature values is discussed. ((orig.))

  13. Nuclear Shadowing Effect on the K Factor in Au-Au Collisions

    2002-01-01

    We investigate the nuclear shadowing effect on the K factor in the Drell-Yan process by introducing a shadowing factor into the corresponding quantum chromodynamical αs order corrections. K factors for Au-Au collisions are calculated at the centre-of-mass system energies √s = 60, 130 and 200 GeV while the nuclear shadowing factor is taken into account. The numerical results indicate that the nuclear shadowing factor obviously raises the K value in the small x region, and for the same nucleon the K value becomes smaller as the energy increases. The nuclear shadowing effect could be one reason for creating the non-constancy of the K factor.

  16. Radiation sterilization centres worldwide

    International Nuclear Information System (INIS)

    Commercial radiation sterilization has been used for more than 50 years. The Ethicon Division of Johnson and Johnson inaugurated medical device sterilization in 1954 for use with sutures. Over the decades, there has been enormous growth in the disposable medical products market. With this, there has been significant growth in the use of ionizing radiation as a method for sterilization. At present, 40-50% of all disposable medical products manufactured in North America are radiation sterilized. There are now some 160 commercial 60Co irradiators for radiation sterilization operating in 47 countries worldwide, containing approximately 240-260 MCi (8.9-9.6 x 1018 Bq) of gamma emitting 60Co. Included in this are service type facilities operated in research and development centres. Because of the ability to downscale 60Co units, there are many R and D and pilot scale small facilities as well, almost equal in number (approximately 150). When other uses are taken into account, there are in total over 200 gamma irradiators being operated for a variety of purposes in 55 different countries: 100-120 gamma irradiators are located in Europe and in the United States of America. Syringes, surgical gloves, gowns, masks, sticking plasters, dressings, medical 'tetrapacks', bottle teats for premature babies, artificial joints, food packaging, raw materials for pharmaceuticals and cosmetics, and even wine corks, are gamma sterilized. An increasing number of e-beam accelerators are also being operated, but at present e-beam is used for only a minority of radiation sterilized product. The use of e-beam as a radiation source has many attractive features, such as near instantaneous dose delivery, scalability for different throughput, and the capability to integrate in an on-line process. E-beam processing is, however, limited by the penetration of electrons, which is proportional to the accelerator voltage. The highest electron energy used in commercial applications, 10 MeV, penetrates

    RTEMS CENTRE - Support and Maintenance Centre to RTEMS Operating System is a joint ESA/Portuguese Task Force initiative to develop a support and maintenance centre to the Real-Time Executive for Multiprocessor Systems (RTEMS). This paper gives a high level visibility of the progress, the results obtained and the future work in the RTEMS CENTRE [6] and in the RTEMS Improvement [7] projects. RTEMS CENTRE started officially in November 2006, with the RTEMS 4.6.99.2 version. A full analysis of RTEMS operating system was produced. The architecture was analysed in terms of conceptual, organizational and operational concepts. The original objectives [1] of the centre were primarily to create and maintain technical expertise and competences in this RTOS, to develop a website to provide the European Space Community an entry point for obtaining support (http://rtemscentre.edisoft.pt), to design, develop, maintain and integrate some RTEMS support tools (Timeline Tool, Configuration and Management Tools), to maintain flight libraries and Board Support Packages, to develop a strong relationship with the World RTEMS Community and finally to produce some considerations in ARINC-653, DO-178B and ECSS E-40 standards. RTEMS Improvement is the continuation of the RTEMS CENTRE. Currently the RTEMS, version 4.8.0, is being facilitated for a future qualification. In this work, the validation material is being produced following the Galileo Software Standards Development Assurance Level B [5]. RTEMS is being completely tested, errors analysed, dead and deactivated code removed and tests produced to achieve 100% statement and decision coverage of source code [2]. The SW to exploit the LEON Memory Management Unit (MMU) hardware will be also added. A brief description of the expected implementations will be given.

Méthodes Il s'agit d'une étude rétrospective descriptive et analytique menée sur 8 ans (Janvier 2005-Décembre 2012) dans le service d'hépato-gastroentérologie (HGE) du CHU Campus de Lomé. Etaient inclus les dossiers des patients hospitalisés pour CO confirmé histologiquement. Résultats Sur 8 ans, 24 patients remplissant nos critères d'inclusion ont été retenus soit 3cas de CO par an et 0,55% des hospitalisations. L’âge moyen des patients était de 57,08 ans (extrêmes: 32 et 82 ans). La dysphagie et l’épigastralgie étaient les motifs d'hospitalisation les plus rencontrés. L'alcool (n=15), le tabac (n=13) étaient les facteurs de risque les plus présents. A la fibroscopie, les lésions étaient ulcéro-bourgeonnantes et hémorragiques (n=12), ulcéro-bourgeonnantes (n=5); ces lésions siégeaient au niveau du 1/3 inférieur (n= 11), à l'union 1/3 supérieur 1/3moyen de l’œsophage (n= 13) et aucun au niveau du 1/3 supérieur. Seize lésions étaient des carcinomes épidermoïdes et 3 des adénocarcinomes. L’évolution dans le service a été fatale dans 2cas; 16 patients avaient été transférés en chirurgie pour des soins palliatifs et 5 patients (20,8%) étaient perdus de vue. Conclusion Le CO semble en augmentation au Togo. L'alcool et le tabac sont les facteurs de risque et le pronostic sévère dans notre série est lié au retard diagnostic. Son dépistage précoce passe par une consultation rapide devant toute dysphagie chez un sujet de 50 ans et plus. PMID:25883742

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr{sub 1-c}Au{sub c} with 0.5 ≤ c and Mn{sub 1-c}Au{sub c} with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ{sub 3d} due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ{sub 3d} and E{sub F} in liquid binary TM-M alloys at a composition of 50 at% TM.

    Retrospective analysis of 17 patients with intracranial germ cell tumors treated in a multidisciplinary consultation at the Bordeaux University Hospital a and literature review. Seventeen consecutive patients were treated from 1978 to 1995 for a primary intracranial germ cell tumor. Median age was 14 (range 3-29 years). There were two malignant teratoma, six proved germinoma and nine presumed germinoma (diagnostic based on biological, radiological and treatment criteria). All received radiotherapy from 30 to 60 Gy (median 40 Gy) in different volumes. Chemotherapy was administered in 15 cases, three after surgery and 12 after radiotherapy. All tumours were in complete remission after initial treatment. The two malignant teratomas recurred in non-irradiated area after nine and 48 months, and the patients died. None of the germinoma recurred within a follow-up period of two to 17 years (median 65 months). Five and 10 year actuarial overall survival rates were the same: 84 % for all histories and 100 % for germinomas. Only two patients developed school difficulties and six presented an hypopituitarism, of which one was consecutive to radiotherapy. Chemotherapy was well tolerated. This retrospective study and literature analysis are in favor of limited dose and volume of radiation therapy associated with chemotherapy. (authors)

  11. Formation Mechanism and Binding Energy for Body-Centred Regular Octahedral Structure of Li7 Cluster

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The formation mechanism for the body-centred regular octahedral structure of Lh cluster is proposed. The curve of the total energy versus the separation R between the nucleus at tie centre and nuclei at the apexes for this structure of Lh has been calculated by using the method of Gou's modified arrangement channel quantum mechanics (MACQM). The result shows that the curve has a minimal energy of-52.169 73 a.u. at R= 5.06a0. When R approaches infinity, the totai energy of seven lithium atoms has the value of -51.996 21 a.u. So the binding energy of Lh with respect to seven lithium atoms is 0.173 52 a.u. Therefore the binding energy per atom for hit is 0.024 79 a.u. or 0.674 eV, which is greater than the binding energy per atom of 0.453 eV for Lii, the binding energy per atom of 0.494 eV for Liz and the binding energy per atom of 0.632 eV for Li& calculated previously by us. This means that the Lh cluster may be formed stably in a body-centred regular octahedral structure with a greater binding energy.

    The formation mechanism for the body-centred regular tetrahedral structure of Li5 cluster is proposed.The curve of the total energy versus the separation R between the nucleus at the centre and nuclei at the apexes for this structure of Li5 has been calculated by using the method of Gou's modified arrangement channel quantum mechanics(MACQM). The result shows that the curve has a minimal energy of-37.2562 a.u. at R = 14.5a0. When R approaches infinity the total energy of five lithium atoms has the value of-37.1401 a.u. So the binding energy of Li5 with respect to five lithium atoms is the difference of 0.1161 a.u. for the above two energy values. Therefore the binding energy per atom for Li5 is 0.023 22 a.u., or 0.632 eV, which is greater than the binding energy per atom of 0.453 eV for Li2 and the binding energy per atom of 0.494 eV for Li3 calculated previously by us. This means that the Li5 cluster may be formed stably in a body-centred regular tetrahedral structure with a greater binding energy.

    The formation mechanism for the body-centred regular icosahedral structure of Li13 cluster is proposed. The curve of the total energy versus the separation R between the nucleus at the centre and nuclei at the apexes for this structure of Li13 has been calculated by using the method of Gou's modified arrangement channel quantum mechanics (MACQM). The result shows that the curve has a minimal energy of-96.951 39 a.u. at R = 5.46a0. When R approaches to infinity, the total energy of thirteen lithium atoms has the value of-96.564 38 a.u. So the binding energy of Li13 with respect to thirteen lithium atoms is 0.387 01 a.u. Therefore the binding energy per atom for Li13 is 0.029 77 a.u. or 0.810 eV, which is greater than the binding energy per atom of 0.453 eV for Li2, 0.494 eV for Lia, 0.7878 eV for Li4, 0.632 eV for Lis, and 0.674 eV for Lit calculated by us previously. This means that the Li13 cluster may be formed stably in a body-centred regular icosahedral structure with a greater binding energy.

  15. The Galactic centre pulsar population

    CERN Document Server

    Chennamangalam, Jayanth

    2013-01-01

    The recent discovery of a magnetar in the Galactic centre region has allowed Spitler et al. to characterize the interstellar scattering in that direction. They find that the temporal broadening of the pulse profile of the magnetar is substantially less than that predicted by models of the electron density of that region. This raises the question of what the plausible limits for the number of potentially observable pulsars - i.e., the number of pulsars beaming towards the Earth - in the Galactic centre region are. In this paper, using realistic assumptions, we show that the potentially observable population of pulsars in the inner parsec has a conservative upper limit of $\\sim$950, and that it is premature to conclude that the number of pulsars in this region is small. We also show that the observational results so far are consistent with this number and make predictions for future radio pulsar surveys of the Galactic centre.

    We present here a technological platform for engineering Au nanotopographies by templated electrodeposition on antibacterial surfaces. Three different types of nanostructures were fabricated: nanopillars, nanorings and nanonuggets. The nanopillars are the basic structures and are 50 nm in diameter and 100 nm in height. Particular arrangement of the nanopillars in various geometries formed nanorings and nanonuggets. Flat surfaces, rough substrate surfaces, and various nanostructured surfaces were compared for their abilities to attach and kill bacterial cells. Methicillin-resistant Staphylococcus aureus, a Gram-positive bacterial strain responsible for many infections in health care system, was used as the model bacterial strain. It was found that all the Au nanostructures, regardless their shapes, exhibited similar excellent antibacterial properties. A comparison of live cells attached to nanotopographic surfaces showed that the number of live S. aureus cells was technological platform for engineering Au nanotopographies by templated electrodeposition on antibacterial surfaces.

  19. Training centres in Latin America

    International Nuclear Information System (INIS)

    Early 1958 the Brazilian representative on the Board of Governors of the International Atomic Energy Agency - supported by the Governors from Argentina and Guatemala -proposed that a study should be made of the possibility of setting up one or more atomic energy training centres in Latin America. On the Board's recommendation, the Director General of the Agency appointed a fact-finding team to make anon-the-spot study. In drafting this report the team was invited to consider the following points: (a) The need for establishing one or more regional training centres; (b) Existing facilities that are being or could be used for training, together with technical data concerning them; (c) The general scientific technological and industrial conditions of the countries visited insofar as they have a bearing on their training needs and capabilities. The authors of the report conclude that 'a training centre in radio-botany should provide vitally needed knowledge and vitally needed specialists to all the agricultural installations in Latin America. A training centre like this might provide an excellent model upon which to base training centres in other areas'. The report recommends that: 1. The Agency should meet the requests of Latin American universities by, for example, supplying equipment and sending experts; 2. At least one specialized training centre should be established as soon as possible. Taking as an example the field of radio-botany, such a centre would provide trained specialists in radio-botany to agricultural institutions throughout Latin America and also provide basic research results vital to agriculture. The cost of new facilities might be of the order of $7 500 000, with an annual budget of approximately $650 000. Staff required: 40 scientists and 175 employees; 3. Whenever it appears feasible to gather necessary staff of high creative ability and established productivity and when funds can be made available for facilities, equipment and operating costs, at

  20. Magnetic susceptibilities of liquid Cr-Au, Mn-Au and Fe-Au alloys

    International Nuclear Information System (INIS)

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr1-cAuc with 0.5 ≤ c and Mn1-cAuc with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ3d due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ3d and EF in liquid binary TM-M alloys at a composition of 50 at% TM

    Cette étude a pour objectif d’évaluer la fréquence des facteurs de risque cardiovasculaires au cours du lupus et de préciser leur prévalence. Etude rétrospective portant sur 250 patients ayant un lupus, diagnostiqué selon les critères de l'ACR, hospitalisés entre 1970 et 2013. Les données cliniques et para cliniques ont été recueillies à partir des observations médicales. Il s'agit de 228 femmes et 22 hommes d’âge moyen au diagnostic du lupus de 30, 32 ans (extrêmes: 16-69). La durée moyenne du suivi des patients était de 64 mois (extrêmes: 7 jours- 382mois). Quatre vingt dix patients (36%) étaient hypertendus, 74% avaient une hypercholestérolémie et 22% étaient diabétiques. Pour les autres facteurs de risque cardiovasculaire traditionnels, un âge > 50 ans a été retrouvé dans 40% des cas, le sexe masculin dans 8% des cas, l'obésité dans 76% des cas et le tabagisme dans 11% des cas. Les facteurs de risque surajoutés sont représentés par la présence des anticorps antiphospholipides (47% des cas), la néphropathie lupique (49% des cas), l'insuffisance rénale (42% des cas), la corticothérapie au long cours (74% des cas) et la chronicité de la maladie dans 35% des cas. Les complications cardiovasculaires retrouvées dans notre série étaient: les accidents vasculaires cérébraux (2%) et l'insuffisance coronarienne (5,6%). Devant l'importance du risque cardiovasculaire au cours du lupus, une surveillance rapprochée des facteurs de risque cardio-vasculaires semble primordiale chez les lupiques. PMID:27022427

    2013-07-01

    Hierarchical Au-Co(OH)2 microclusters have been synthesized by a facile ethanol-assisted hydrothermal method on FTO glass substrates. The as-fabricated Au-Co(OH)2 forms a typical wreath-shaped structure on a nanosheet with an urchin-like Au-Co(OH)2 structure located in the centre surrounded by densely grown Co(OH)2 nanoarrays. Morphological evolution of the Au-Co(OH)2 microclusters through intermediate steps could be identified by varying the reaction time. The incorporated electronegative Au may be responsible for the decrease of binding energy of Au-Co(OH)2 compared to Co(OH)2. The Au-Co(OH)2 electrode was found to be a promising catalyst for the oxygen evolution reaction (OER) in neutral pH solutions, with a larger roughness factor, lower OER onset and much higher current density than a Co(OH)2 electrode. The improvement of the OER activity of Au-Co(OH)2 microclusters may be due to their large surface area provided by the 3D network of microclusters, and the incorporation of Au as an electron sink to facilitate the oxidation of Co(ii) and Co(iii) to Co(iv).Hierarchical Au-Co(OH)2 microclusters have been synthesized by a facile ethanol-assisted hydrothermal method on FTO glass substrates.

    2011-01-01

    Full Text Available Abstract The use of nanowires (NWs for labeling, sensing, and sorting is the basis of detecting biomolecules attached on NWs by optical and magnetic properties. In spite of many advantages, the use of biomolecules-attached NWs sensing by photoelectrochemical (PEC study is almost non-existent. In this article, the PEC study of dye-attached single-stranded DNA on Au NWs and Au-Ni-Au multilayer NWs prepared by pulse electrodeposition are investigated. Owing to quantum-quenching effect, the multilayer Au NWs exhibit low optical absorbance when compared with Au NWs. The tagged Au NWs show good fluorescence (emission at 570 nm, indicating significant improvement in the reflectivity. Optimum results obtained for tagged Au NWs attached on functionalized carbon electrodes and its PEC behavior is also presented. A twofold enhancement in photocurrent is observed with an average dark current of 10 μA for Au NWs coated on functionalized sensing electrode. The importance of these PEC and optical studies provides an inexpensive and facile processing platform for Au NWs that may be suitable for biolabeling applications.

Méthodes Il s'agit d'une étude transversale menée de Mai 2011 à Juin 2012 dans le service de Médecine du CHU de Parakou. Ont été inclus tous les adultes séropositifs au VIH vus en consultation ou hospitalisés. Les données ont été collectées par interviews et dépouillement de dossiers médicaux. L'antigène HBs a été recherché par un test rapide et l'ALAT a été dosé. L'analyse des données a été faite avec le logiciel EpiInfo 3.5.1. Les proportions ont été comparées grâce au test de Chi-deux ou au test de Fisher au seuil de significativité de 5%. Un modèle de régression logistique multivariable a permis d'expliquer la prévalence de l'hépatite B. Résultats Sur les 744 sujets inclus on a dénombré 555 femmes. L’âge moyen était de 35,5 + 10,1 ans. La prévalence de l'hépatite B a été estimée à 16,9% (IC95: 14,3%-19,9%). Cette prévalence était plus élevée chez les sujets originaires du Borgou/Alibori et ceux au stade 4 de l'OMS. Conclusion La prévalence de la co-infection VIH/VHB au CHU Parakou est élevée. Le dispositif national de prise en charge et de prévention de l'hépatite B chez les personnes séropositives au VIH doit être renforcé. PMID:26097629

    Full Text Available Objectifs : cette étude avait pour objectifs de déterminer les profils épidémiologiques, diagnostiques et thérapeutiques de la rhabdomyolyse post-traumatique, déterminer les facteurs de risque d’IRA au cours de rhabdomyolyse et évaluer les aspects évolutifs. Méthodes : nous avons réalisé une étude transversale rétrospective, descriptive et analytique sur 3 ans à l’USIC de l’HPD, s’étendant du 1er Août 2011 au 31 Septembre 2014. Résultats : une prévalence hospitalière de 29,1% était trouvée. L’âge moyen était de 40,7 ans. 83,3 % de nos patients étaient de sexe masculin. 58,3 % étaient oligo-anuriques à l’admission. Le taux moyen de Créatinine était de 31 mg /L. 58,3 % avaient un taux de CPK inférieur à 5000 UI/L contre 29,3% qui avaient une rhabdomyolyse sévère. 41,7 % avaient une hyperkaliémie. Le polytraumatisme par AVP était la première cause de rhabdomyolyse. Tous les patients avaient bénéficié d’une réhydratation. 20,8 % ont été hémodialysés. L’évolution de la fonction rénale était favorable dans 25 % de cas. 75 % de patients avec IRA étaient décédés. En analyse multivariée, ni l’hypotension artérielle ni le taux de CPK n’avaient constitué de facteurs de risque indépendants de l’IRA au cours de rhabdomyolyse post-traumatique. Conclusion: l’IRA au cours de la rhabdomyolyse post-traumatique reste un événement fréquent dont l’épidémiologie et le diagnostic ont été décrits et les facteurs étiologiques sont dominés par les polytraumatismes de l’AVP et les brûlures. Un traitement préhospitalier par l’expansion volémique et l’épuration extra-rénale restent les clés de traitement.

  7. Identified Particle Dependence of Nuclear Modification Factors in d+Au Collisions at RHIC

    CERN Document Server

    Barnby, L S

    2004-01-01

    We present transverse momentum spectra from d+Au collisions at sqrt(s_NN) = 200 GeV for identified hadrons at mid-rapidity and unidentified hadrons in the forward rapidity region using the Solenoidal Tracker at RHIC. We scale these spectra by the mean number of binary collisions to form a transverse momentum dependent ratio to spectra from p+p collisions, showing that the Cronin effect measured at lower centre-of-mass energies is also present at this higher energy. The data also suggest a dependence of the Cronin effect on the hadron species. We also compare central d+Au collisions to more peripheral ones, contrasting the behaviour to that observed in Au+Au collisions and remark on unidentified hadrons at forward rapidities which show a qualitatively different behaviour.

    International Nuclear Information System (INIS)

    Colour centres produced by X-ray irradiation of barium hexaaluminate (phase I) with β-alumina structure are studied by electron paramagnetic resonance, optical absorption, and thermally stimulated luminescence. It is shown that in addition to the F+ centres characteristic of β-alumina phases, this compound presents other colour centres such as F, O-, and possibly V-type centres. The stability of these defects is investigated by means of thermal bleaching experiments and thermally stimulated luminescence. An alternative model to the generally accepted one is proposed, for the F+ centres, together with a mechanism of defect formation. (author)

  10. Sensing data centres for energy efficiency.

    Science.gov (United States)

    Liu, Jie; Terzis, Andreas

    2012-01-13

    Data centres are large energy consumers today, and their consumption is expected to increase further, driven by the growth in cloud services. The large monetary cost and the environmental impact of this consumption have motivated operators to optimize data centre management. We argue that one of the underlying reasons for the low-energy utilization is the lack of visibility into a data centre's highly dynamic operating conditions. Wireless sensor networks promise to remove this veil of uncertainty by delivering large volumes of data collected at high spatial and temporal fidelities. The paper summarizes data centre operations in order to describe the parameters that a data centre sensing network should collect and motivate the challenges that such a network faces. We present technical approaches for the problems of data collection and management and close with an overview of a data centre genome, an end-to-end data centre sensing system. PMID:22124086

  12. Multifragmentation in Au + Au collisions studied with AMD-V

    International Nuclear Information System (INIS)

    AMD-V is an optimum model for calculation of multifragmentation in Au + Au collisions. AMD-V consider anti-symmetry of incident nucleus, target nucleus and fragments, furthermore, it treat the quantum effect to exist many channels in the intermediate and final state. 150 and 250 MeV/nucleon incident energy were used in the experiments. The data of multifragment atom in 197Au + 197Au collisions was reproduced by AMD-V calculation using Gognny force, corresponding to the imcompressibility of nuclear substance K = 228 MeV and its mean field depend on momentum. When other interaction (SKG 2 force, corresponding to K = 373 KeV) was used an mean field does not depend on momentum, the calculation results could not reproduce the experimental values, because nucleus and deuteron were estimated too large and α-particle and intermediate fragments estimated too small.

  15. Perceptual centres in speech - an acoustic analysis

    Science.gov (United States)

    Scott, Sophie Kerttu

    Perceptual centres, or P-centres, represent the perceptual moments of occurrence of acoustic signals - the 'beat' of a sound. P-centres underlie the perception and production of rhythm in perceptually regular speech sequences. P-centres have been modelled both in speech and non speech (music) domains. The three aims of this thesis were toatest out current P-centre models to determine which best accounted for the experimental data bto identify a candidate parameter to map P-centres onto (a local approach) as opposed to the previous global models which rely upon the whole signal to determine the P-centre the final aim was to develop a model of P-centre location which could be applied to speech and non speech signals. The first aim was investigated by a series of experiments in which a) speech from different speakers was investigated to determine whether different models could account for variation between speakers b) whether rendering the amplitude time plot of a speech signal affects the P-centre of the signal c) whether increasing the amplitude at the offset of a speech signal alters P-centres in the production and perception of speech. The second aim was carried out by a) manipulating the rise time of different speech signals to determine whether the P-centre was affected, and whether the type of speech sound ramped affected the P-centre shift b) manipulating the rise time and decay time of a synthetic vowel to determine whether the onset alteration was had more affect on P-centre than the offset manipulation c) and whether the duration of a vowel affected the P-centre, if other attributes (amplitude, spectral contents) were held constant. The third aim - modelling P-centres - was based on these results. The Frequency dependent Amplitude Increase Model of P-centre location (FAIM) was developed using a modelling protocol, the APU GammaTone Filterbank and the speech from different speakers. The P-centres of the stimuli corpus were highly predicted by attributes of

  18. High resolution optical spectroscopy in isotopically-pure Si using radioactive isotopes: towards a re-evaluation of deep centres

    CERN Multimedia

    2008-01-01

    Deep centres in silicon have been studied in great detail over the last 50 years and much progress has been made in the understanding and control of impurities in this material. Much of this effort has been focussed on the problems of metallic impurities such as Fe, Ag, Cu and Au. These are impurities that diffuse quickly into the crystal and hamper device performance. Although the understanding of these impurity centres in Si is widely thought to be "solved" recent experiments with isotopically-pure Si are disproving long-held results and are opening up new perspectives on the constitutent nature of deep centres in Si. In particular, there is new evidence to show that the family of Cu, Ag and Au may all show essentially the same behaviour by forming a cluster of $\\textbf{any four atoms}$ of these elements. This has been established for Cu and Ag through the use of different stable isotopes in the preparation of samples, but the case of Au remains unproven since there is only one stable Au isotope. In this pr...

    The determination of the stiffness center of a machine tool is a major element for knowing the dynamic behavior of this one. This stiffness center can be obtained from a static characterization of the machine tool. For an operation of turning, we present an experimental protocol to determine the stiffness matrix, then by inversion, the associated flexibility matrix. This step makes it possible to establish the privileged directions of the movement associated with the maximum and minimal stiffness as well as the stiffness center. Through this step, it is observed that, at the time of an operation of turning, the movement of the point of the tool is carried out according to an ellipse located in a tilted average plan compared to the machine spindle. This movement is linked with the self-excited vibrations. This analysis could be exploited and transposed in the case of the High Speed Machining. It will make it possible to predict various aspects of machining related to the behavior of the tool in the process of ...

  14. Laparoscopic adrenalectomy: Single centre experience.

    LENUS (Irish Health Repository)

    O'Farrell, N J

    2012-02-01

    BACKGROUND: Laparoscopic adrenalectomy is an attractive alternative to the traditional open approach in the surgical excision of an adrenal gland. It has replaced open adrenalectomy in our institution and we review our experience to date. METHODS: All cases of laparoscopic adrenalectomies in our hospital over eight years (from 2001 to May 2009) were retrospectively reviewed. Patient demographics, diagnosis, length of hospital stay, histology and all operative and post-operative details were evaluated. RESULTS: Fifty-five laparoscopic adrenalectomies (LA) were performed on 51 patients over eight years. The mean age was 48 years (Range 16-86 years) with the male: female ratio 1:2. Twenty-three cases had a right adrenalectomy, 24 had a left adrenalectomy and the remaining four patients had bilateral adrenalectomies. 91% were successfully completed laparoscopically with five converted to an open approach. Adenomas (functional and non functional) were the leading indication for LA, followed by phaeochromocytomas. Other indications for LA included Cushing\\'s disease, adrenal malignancies and rarer pathologies. There was one mortality from necrotising pancreatitis following a left adrenalectomy for severe Cushing\\'s disease, with subsequent death 10 days later. CONCLUSION: Laparoscopic adrenalectomy is effective for the treatment of adrenal tumours, fulfilling the criteria for the ideal minimally invasive procedure. It has replaced the traditional open approach in our centre and is a safe and effective alternative. However, in the case of severe Cushing\\'s disease, laparoscopic adrenalectomy has the potential for significant adverse outcomes and mortality.

    International Nuclear Information System (INIS)

    The paper describes in general terms the physical security situation at the RACSO nuclear centre and the principal measures adopted to deal with the risk of subversive activities. Since 1980, Peru had to face terrorist problems; therefore, measures were adopted at RACSO to deal with this risk. As a result, it has been possible to keep the nuclear centre free from terrorist attacks. (author)

  19. Communications strategy for the Chernobyl Centre

    International Nuclear Information System (INIS)

    This Communications Strategy was developed for the International Chernobyl Centre (ICC) as part of a joint UK/Ukraine project, sponsored by the Department of Trade and Industry and NNC Limited. The Plan was developed during four weeks of workshop discussions in the UK between staff from the centre and experienced PR Professionals from NNC Limited. The requirements for a sustained communications activity at the ICC go much further than simply enhancing or promoting the Centre's scientific and technical activities. Raising sufficient awareness of the Centre among potential funding agents and commercial partners is critical to its future development as a major centre for international co-operation and research. It is only through establishing and developing effective communications that the Centre will become well enough known and understood both within the Ukraine, and internationally, to secure its long term future. However, as the workshop programme unfolded, it also became clear that communications was in itself a legitimate and necessary function of the Centre, and part of the foundations of its existence. The Centre has a fundamental role as an 'information exchange', collecting and communicating information from within the Ukraine to the rest of the world, and interpreting world interest and attitudes to the Ukraine Government and nuclear industry. As such compliments the efforts of individual power plant and corporate PR functions within the Ukraine nuclear energy sector

  20. New structures near the compact radio source at the Galactic Centre

    International Nuclear Information System (INIS)

    Sixteen years ago, a bright compact radio source, Sgr A*, was found at the Galactic Centre, as had been predicted. The characteristics of its emission and the kinematics of gas near it have been used to argue for the presence of a black hole of 500-5 x 106 solar masses at the Galactic Centre. Here we present high-resolution (<0.2 arcsec) radio images, made at 2-cm wavelength, of the central arcsecond of the Galaxy. Sgr A* is surrounded by at least four satellite radio features. Interpreted as thermally emitting blobs of plasma, they have typical sizes <1,700 AU and are within a projected distance of 3,500 AU from Sgr A*. Another set of larger radio features, 2-4 arcsec from Sgr A*, shows a regular progression of galactocentric distance with position angle. The placement and appearance of all these structures lead us to suggest that they are physically associated with Sgr A*; if so, they can be used as probes of the immediate vicinity of the possible massive black hole at the Galactic Centre.

    Taylor, Lucas

    2009-01-01

    The CMS Experiment at the LHC is establishing a global network of inter-connected "CMS Centres" for controls, operations and monitoring. These support: (1) CMS data quality monitoring, detector calibrations, and analysis; and (2) computing operations for the processing, storage and distribution of CMS data. We describe the infrastructure, computing, software, and communications systems required to create an effective and affordable CMS Centre. We present our highly successful operations experiences with the major CMS Centres at CERN, Fermilab, and DESY during the LHC first beam data-taking and cosmic ray commissioning work. The status of the various centres already operating or under construction in Asia, Europe, Russia, South America, and the USA is also described. We emphasise the collaborative communications aspects. For example, virtual co-location of experts in CMS Centres Worldwide is achieved using high-quality permanently-running "telepresence" video links. Generic Web-based tools have been developed ...

  2. The role of the sexual assault centre.

    2013-02-01

    Sexual Assault Centres provide multidisciplinary care for men and women who have experienced sexual crime. These centres enable provision of medical, forensic, psychological support and follow-up care, even if patients chose not to report the incident to the police service. Sexual Support Centres need to provide a ring-fenced, forensically clean environment. They need to be appropriately staffed and available 24 hours a day, 7 days a week to allow prompt provision of medical and supportive care and collection of forensic evidence. Sexual Assault Centres work best within the context of a core agreed model of care, which includes defined multi-agency guidelines and care pathways, close links with forensic science and police services, and designated and sustainable funding arrangements. Additionally, Sexual Assault Centres also participate in patient, staff and community education and risk reduction. Furthermore, they contribute to the development, evaluation and implementation of national strategies on domestic, sexual and gender-based violence.

  3. Multiscale Modeling of Au-Island Ripening on Au(100

    2011-01-01

    Full Text Available We describe a multiscale modeling hierarchy for the particular case of Au-island ripening on Au(100. Starting at the microscopic scale, density functional theory was used to investigate a limited number of self-diffusion processes on perfect and imperfect Au(100 surfaces. The obtained structural and energetic information served as basis for optimizing a reactive forcefield (here ReaxFF, which afterwards was used to address the mesoscopic scale. Reactive force field simulations were performed to investigate more diffusion possibilities at a lower computational cost but with similar accuracy. Finally, we reached the macroscale by means of kinetic Monte Carlo (kMC simulations. The reaction rates for the reaction process database used in the kMC simulations were generated using the reactive force field. Using this strategy, we simulated nucleation, aggregation, and fluctuation processes for monoatomic high islands on Au(100 and modeled their equilibrium shape structures. Finally, by calculating the step line tension at different temperatures, we were able to make a direct comparison with available experimental data.

    2011-01-01

    The Canadian Astronomy Data Centre (CADC) is the world's largest astronomical data center, holding over 0.5 Petabytes of information, and serving nearly 3000 astronomers worldwide. Its current data collections include BLAST, CFHT, CGPS, FUSE, Gemini, HST, JCMT, MACHO, MOST, and numerous other archives and services. It provides extensive data archiving, curation, and processing expertise, via projects such as MegaPipe, and enables substantial day-to-day collaboration between resident astronomers and computer specialists. It is a stable, powerful, persistent, and properly supported environment for the storage and processing of large volumes of data, a condition that is now absolutely vital for their science potential to be exploited by the community. Through initiatives such as the Common Archive Observation Model (CAOM), the Canadian Virtual Observatory (CVO), and the Canadian Advanced Network for Astronomical Research (CANFAR), the CADC is at the global forefront of advancing astronomical research through improved data services. The CAOM aims to provide homogeneous data access, and hence viable interoperability between a potentially unlimited number of different data collections, at many wavelengths. It is active in the definition of numerous emerging standards within the International Virtual Observatory, and several datasets are already available. The CANFAR project is an initiative to make cloud computing for storage and data-intensive processing available to the community. It does this via a Virtual Machine environment that is equivalent to managing a local desktop. Several groups are already processing science data. CADC is also at the forefront of advanced astronomical data analysis, driven by the science requirements of astronomers both locally and further afield. The emergence of 'Astroinformatics' promises to provide not only utility items like object classifications, but to directly enable new science by accessing previously undiscovered or intractable

  6. Big Surveys, Big Data Centres

    Science.gov (United States)

    Schade, D.

    2016-06-01

    Well-designed astronomical surveys are powerful and have consistently been keystones of scientific progress. The Byurakan Surveys using a Schmidt telescope with an objective prism produced a list of about 3000 UV-excess Markarian galaxies but these objects have stimulated an enormous amount of further study and appear in over 16,000 publications. The CFHT Legacy Surveys used a wide-field imager to cover thousands of square degrees and those surveys are mentioned in over 1100 publications since 2002. Both ground and space-based astronomy have been increasing their investments in survey work. Survey instrumentation strives toward fair samples and large sky coverage and therefore strives to produce massive datasets. Thus we are faced with the "big data" problem in astronomy. Survey datasets require specialized approaches to data management. Big data places additional challenging requirements for data management. If the term "big data" is defined as data collections that are too large to move then there are profound implications for the infrastructure that supports big data science. The current model of data centres is obsolete. In the era of big data the central problem is how to create architectures that effectively manage the relationship between data collections, networks, processing capabilities, and software, given the science requirements of the projects that need to be executed. A stand alone data silo cannot support big data science. I'll describe the current efforts of the Canadian community to deal with this situation and our successes and failures. I'll talk about how we are planning in the next decade to try to create a workable and adaptable solution to support big data science.

    2003-01-01

    The present work proposes a theoretical method called ionization dynamics to derive the ionic charge state distribution. Using relativistic quantum mechanics to calculate the energy level lifetime and average ionic lifetime of each ion, the first-order ionization rate constant can be obtained. Based on these data, from the solution of differential equations for consecutive-irreversible ionization reactions, one will be able to derive the ionic charge state distribution.The calculated average positive charge 49.24 of Au48+ ~ Au52+ and their relative distribution are in good agreement with the results of Lawrence Livermore National Laboratory.

  12. Towards Human-Centred Design

    Bannon, Liam J.

    The field of HCI has evolved and expanded dramatically since its origin in the early 1980’s. The HCI community embraces a large community of researchers and practitioners around the world, from a variety of disciplinary backgrounds in the human and social sciences, engineering and informatics, and more recently, the arts and design disciplines. This kaleidoscope of cultures and disciplines as seen at INTERACT Conferences provides a rich pool of resources for examining our field. Applications are increasingly exploring our full range of sensory modalities, and merging the digital and physical worlds. WiFi has opened up a huge design space for mobile applications. A focus on usability of products and services has been complemented by an emphasis on engagement, enjoyment and experience. With the advent of ubiquitous computing, and the emergence of “The Internet of Things”, new kinds of more open infrastructures make possible radically new kinds of applications. The sources of innovation have also broadened, to include human and social actors outside of the computing and design organizations. The question is to what extent is our mainstream thinking in the HCI field ready for the challenges of this Brave New World? Do the technological and social innovations that we see emerging require us to re-shape, or even, re-create, our field, or is it a case of a more gradual evolution and development of that which we already know? In this closing Keynote, I will provide a perspective on the evolution and development of the HCI field, looking backwards as well as forwards, in order to determine what are some of the changes of significance in the field. This “broad-brush” approach to what I term “ human-centred design” will be complemented by the examination of specific projects and applications, to help anchor some of the discussion. Areas such as user-centred design, participatory design, computer-supported cooperative work and learning, and interaction design, in

  15. Biosynthesis and stabilization of Au and Au-Ag alloy nanoparticles by fungus, Fusarium semitectum

    International Nuclear Information System (INIS)

    Crystallized and spherical-shaped Au and Au-Ag alloy nanoparticles have been synthesized and stabilized using a fungus, F . semitectum in an aqueous system. Aqueous solutions of chloroaurate ions for Au and chloroaurate and Ag+ ions (1 : 1 ratio) for Au-Ag alloy were treated with an extracellular filtrate of F . semitectum biomass for the formation of Au nanoparticles (AuNP) and Au-Ag alloy nanoparticles (Au-AgNP). Analysis of the feasibility of the biosynthesized nanoparticles and core-shell alloy nanoparticles from fungal strains is particularly significant. The resultant colloidal suspensions are highly stable for many weeks. The obtained Au and Au-Ag alloy nanoparticles were characterized by the surface plasmon resonance (SPR) peaks using a UV-vis spectrophotometer, and the structure, morphology and size were determined by Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), and transmission electron microscopy (TEM). Possible optoelectronics and medical applications of these nanoparticles are envisaged.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    This paper introduces the concept of‘symmetric centres' of braided monoidal categories. Let H be a Hopf algebra with bijective antipode over a field k. We address the symmetric centre of the Yetter-Drinfel'd module category HH(yD) and show that a left Yetter-Drinfel'd module M belongs to the symmetric centre of HH(yD) if and only if M is trivial. We also study the symmetric centres of categories of representations of quasitriangular Hopf algebras and give a sufficient and necessary condition for the braid of H(M) to induce the braid of (H(H)(A),(○)A,A,φ,l,r), or equivalently, the braid of (A#H(H),(○)A,A,φ,l,r), where A is a quantum commutative H-module algebra.

    Using the FOPI detector at GSI Darmstadt, excitation functions of collective flow components were measured for the Au+Au system, in the reaction plane and out of this plane, at seven incident energies ranging from 100AMeV to 800AMeV. The threshold energies, corresponding to the onset of sideward-flow (balance energy) and squeeze-out effect (transition energy), are extracted from extrapolations of these excitation functions toward lower beam energies for charged products with Z>2. The transition energy is found to be larger than the balance energy. The impact parameter dependence of both balance and transition energies, when extrapolated to central collisions, suggests comparable although slightly higher values than the threshold energy for the radial flow. The relevant parameter seems to be the energy deposited into the system in order to overcome the attractive nuclear forces.

  20. Nuclear Modification of Jet Fragmentation in Au+Au Collisions

    2015-10-01

    The characterization of energy in the quark gluon plasma is facilitated by measurements of modifications to the observed jet fragmentation. A favorable channel of study relies on direct photons created in the initial parton interactions of heavy ion collisions. Such a photon traverses the created medium unscathed and grants us a proxy for the transverse momentum of an away side jet. PHENIX Au+Au data recorded at √{sNN} = 200 GeV during RHIC run 14 benefit from the background rejection capability of the silicon vertex detector, enabling the extraction of a higher purity hadron signal. This advantage, combined with a larger integrated luminosity, allows previous PHENIX measurements of fragmentation functions to be extended to greater jet energies. In this talk, the status of the analysis of direct photon hadron correlations with the new data set will be discussed.

    The system created in non-central relativistic nucleus-nucleus collisions possesses large orbital angular momentum. Due to spin-orbit coupling, particles produced in such a system could become globally polarized along the direction of the system angular momentum. We present the results of Lambda and anti-Lambda hyperon global polarization measurements in Au+Au collisions at sqrt{s_NN}=62.4 GeV and 200 GeV performed with the STAR detector at RHIC. The observed global polarization of Lambda and anti-Lambda hyperons in the STAR acceptance is consistent with zero within the precision of the measurements. The obtained upper limit, |P_{Lambda,anti-Lambda}| <= 0.02, is compared to the theoretical values discussed recently in the literature.

  6. The relativistic two-centre continuum

    International Nuclear Information System (INIS)

    A method is presented to define unique continuum states for the two-centre Dirac Hamiltonian. In the spherical limit these states become the familiar angular momentum eigenstates of the radial Coulomb potential. The different states for a fixed total energy vertical strokeEvertical stroke > m may be distinguished by considering the asymptotic spin-angular distribution of states with unique scattering-phases. First numerical solutions of the two-centre Dirac equation for continuum states are presented. (orig.)

    Although neat gold-thiolate oligomers and polymers made of linear S-Au-S bonds have been well-known, observation of RS-Au-SR linear complexes (RS-being an alkylthiolate group) on Au(111) has been reported only recently. On the basis of the unique geometry and bonding of the RS-Au-SR complex on Au(111), we construct simple geometric models of Au-SR oligomers and polymers on Au(111) by fusing linear S-Au-S units matched to the underlying Au(111) surface lattice. We then optimize these models by density functional theory. The hexagonal geometry of the Au(111) lattice determines three possible angles (60{sup o}, 120{sup o}, and 180{sup o}) for connecting two linear S-Au-S units, which lead to isomerism of the Au-SR oligomers and polymer on Au(111). Here we explore open dimers, trimers, and tetramers and cyclic trimers, tetramers, and hexamers of the Au-SR oligomers on Au(111). We also examine four isomers of the Au-SR polymer on Au(111). We find that the 120{sup o} Au-S-Au angle is preferred in constructing both oligomeric and polymeric isomers. The two polymeric isomers with 120{sup o} Au-S-Au angles are found to be energetically competitive with a previous model proposed for the Au-SR polymer on Au(111). We also discuss potential ways to create Au-SR oligomers on Au(111).

    The IUPAC Thermodynamic Tables Project Centre in London has at its disposal considerable expertise on the production and utilization of high-accuracy equations of state which represent the thermodynamic properties of substances. For some years they have been content to propagate this information by the traditional method of book production, but the increasing use of the computer in industry for process design has shown that an additional method was needed. The setting up of the IUPAC Transport Properties Project Centre, also at Imperial College, whose products would also be in demand by industry, afforded the occasion for a new look at the problem. The solution has been to set up the Imperial College Thermophysical Properties Data Centre, which embraces the two IUPAC Project Centres, and for it to establish a link with the existing Physical Properties Data Service of the Institution of Chemical Engineers, thus providing for the dissemination of the available information without involving the Centres in problems such as those of marketing and advertising. This paper outlines the activities of the Centres and discusses the problems in bringing their products to the attention of industry in suitable form.

    The overall aim of this paper is to draw combined, all-embracing conclusions based on a long-term multidisciplinary research programme on recycling centres in Sweden, focussing on working conditions, environment and system performance. A second aim is to give recommendations for their development of new and existing recycling centres and to discuss implications for the future design and organisation. Several opportunities for improvement of recycling centres were identified, such as design, layout, ease with which users could sort their waste, the work environment, conflicting needs and goals within the industry, and industrialisation. Combining all results from the research, which consisted of different disciplinary aspects, made it possible to analyse and elucidate their interrelations. Waste sorting quality was recognized as the most prominent improvement field in the recycling centre system. The research identified the importance of involving stakeholders with different perspectives when planning a recycling centre in order to get functionality and high performance. Practical proposals of how to plan and build recycling centres are given in a detailed checklist. PMID:26826952

    International Nuclear Information System (INIS)

    In these proceedings, we discuss recent results from d + Au collisions in PHENIX ridge related measurements and their possible hydrodynamic origin. We present the v2 at midrapidity and measurements of the pseudorapidity dependence of the ridge, distinguishing between the d-going and Au-going directions. We investigate the possible geometrical origin by comparing v2 in d + Au to that in p + Pb, Au + Au and Pb + Pb collisions. Future plans to clarify the role of geometry in small collision systems at RHIC are discussed

  17. Decay spectroscopy of $^{178}$Au

    CERN Document Server

    Whitmore, B

    In this thesis, the neutron-deficient nucleus $^{178}$Au is investigated through decay spectroscopy. Si and HPGe detectors were used to analyse the decay radiation of $^{178}$Au and its daughter nuclei. Previous studies have been unable to distinguish decay radiation from different isomeric states of this nucleus. This thesis represents the first time such isomeric discrimination has been achieved, and presents tentative spin assignments of both the ground state and an isomer. The neutron-deficient gold isotopes are an area of interest for the study of shape coexistence. This is the phenomenon exhibited by nuclei able to exist at a number of close lying energy minima, each reflecting a distinct type of deformation. It is hoped that studies such as this can help identify the evolution of nuclear deformation in this region of the nuclear chart.

  19. Fabricating a Homogeneously Alloyed AuAg Shell on Au Nanorods to Achieve Strong, Stable, and Tunable Surface Plasmon Resonances

    KAUST Repository

    Huang, Jianfeng

    2015-08-13

    Colloidal metal nanocrystals with strong, stable, and tunable localized surface plasmon resonances (SPRs) can be useful in a corrosive environment for many applications including field-enhanced spectroscopies, plasmon-mediated catalysis, etc. Here, a new synthetic strategy is reported that enables the epitaxial growth of a homogeneously alloyed AuAg shell on Au nanorod seeds, circumventing the phase segregation of Au and Ag encountered in conventional synthesis. The resulting core–shell structured bimetallic nanorods (AuNR@AuAg) have well-mixed Au and Ag atoms in their shell without discernible domains. This degree of mixing allows AuNR@AuAg to combine the high stability of Au with the superior plasmonic activity of Ag, thus outperforming seemingly similar nanostructures with monometallic shells (e.g., Ag-coated Au NRs (AuNR@Ag) and Au-coated Au NRs (AuNR@Au)). AuNR@AuAg is comparable to AuNR@Ag in plasmonic activity, but that it is markedly more stable toward oxidative treatment. Specifically, AuNR@AuAg and AuNR@Ag exhibit similarly strong signals in surface-enhanced Raman spectroscopy that are some 30-fold higher than that of AuNR@Au. When incubated with a H2O2 solution (0.5 m), the plasmonic activity of AuNR@Ag immediately and severely decayed, whereas AuNR@AuAg retained its activity intact. Moreover, the longitudinal SPR frequency of AuNR@AuAg can be tuned throughout the red wavelengths (≈620–690 nm) by controlling the thickness of the AuAg alloy shell. The synthetic strategy is versatile to fabricate AuAg alloyed shells on different shaped Au, with prospects for new possibilities in the synthesis and application of plasmonic nanocrystals.

  20. Thin-films interdiffusion Ti/Pd/Au, Ti/Au/Pd

    International Nuclear Information System (INIS)

    Rutherford backscattering spectroscopy (RBS) is used to study the interdiffusion in Ti/Pd/Au and Ti/Au/Pd thin films system. The purpose of our study is to prepare an alloy of high resistance against corrosion, due to its important use in space industries, optical and visual receivers. In addition to another scientific results for future applications. Interdiffusion in the Ti/Pd/Au thin film system is measured using Rutherford backscattering. Interdiffusion rates of Pd/Au for temperatures between 200 and 490 centigrade degree have been correlated with the defect structure of the films. Air, as compared with vacuum, annealing enhances interdiffusion in the Ti/Au couple and inhibits interdiffusion in Ti/Pd, Ti/Pd and Ti/Au interdiffusion in the Ti/Pd/Au and Ti/Au/Pd ternary systems is strongly reduced in comparison with interdiffusion in the corresponding Ti/Pd or Ti/Au couples for vacuum annealing.

    2011-09-01

    Two Au(III) complexes of the type [Au(en) 2]Cl 3 ( 2a) and [Au(N-pr-en) 2]Cl 3 ( 3a) were synthesized by reacting Auric acid (HAuCl 4·3H 2O) with 2 equiv. ethylenediamine (en) or N-alkyl substituted ethylenediamine ligands. This metallodrug was characterized by various analytical and spectroscopic techniques such as elemental analysis, UV-Vis, Far-IR, 1H NMR and solution 13C as well as solid 13C and 15N NMR. Potentiality of [Au(en) 2]Cl 3 and [Au(N-pr-en) 2]Cl 3 as an anti-cancer agent were investigated by measuring some relevant physicochemical and biochemical properties such as stability of Au-N bonds by vibrational stretching from Far IR as well as cytotoxicity and stomach cancer cell inhibiting effect, respectively. The solid-state 15N NMR chemical shift shows that the ligand is strongly bound to gold(III) centre via N atoms. The computational study of 2a shows that the gold coordination sphere adopts distorted square planar geometry with bidentate ethylenediamine ligands acting as a tetradentate chelate. While stable in the solution state, the in vitro biological studies performed with these compounds 2a in solution showed higher activity towards the inhibitory effects of the human cancer cell lines such as prostate cancer (PC-3) and gastric carcinoma (SGC-7901) than that of the N-substituted gold(III) complex ( 3a). Cytotoxicity of the new compounds has also been estimated in PC-3 and SGC-7901 cells.

  2. Visits to Tier-1 Computing Centres

    CERN Multimedia

    Dario Barberis

    At the beginning of 2007 it became clear that an enhanced level of communication is needed between the ATLAS computing organisation and the Tier-1 centres. Most usual meetings are ATLAS-centric and cannot address the issues of each Tier-1; therefore we decided to organise a series of visits to the Tier-1 centres and focus on site issues. For us, ATLAS computing management, it is most useful to realize how each Tier-1 centre is organised, and its relation to the associated Tier-2s; indeed their presence at these visits is also very useful. We hope it is also useful for sites... at least, we are told so! The usual participation includes, from the ATLAS side: computing management, operations, data placement, resources, accounting and database deployment coordinators; and from the Tier-1 side: computer centre management, system managers, Grid infrastructure people, network, storage and database experts, local ATLAS liaison people and representatives of the associated Tier-2s. Visiting Tier-1 centres (1-4). ...

  3. UV LED lighting for automated crystal centring

    International Nuclear Information System (INIS)

    A low-cost light-emitting diode (LED) UV source has been developed for facilitating macromolecular sample centring in the X-ray beam. A direct outcome of the exponential growth of macromolecular crystallography is the continuously increasing demand for synchrotron beam time, both from academic and industrial users. As more and more projects entail screening a profusion of sample crystals, fully automated procedures at every level of the experiments are being implemented at all synchrotron facilities. One of the major obstacles to achieving such automation lies in the sample recognition and centring in the X-ray beam. The capacity of UV light to specifically react with aromatic residues present in proteins or with DNA base pairs is at the basis of UV-assisted crystal centring. Although very efficient, a well known side effect of illuminating biological samples with strong UV sources is the damage induced on the irradiated samples. In the present study the effectiveness of a softer UV light for crystal centring by taking advantage of low-power light-emitting diode (LED) sources has been investigated. The use of UV LEDs represents a low-cost solution for crystal centring with high specificity

  8. Colliding with G2 near the Galactic Centre: a geometrical approach

    CERN Document Server

    Marcos, R de la Fuente

    2013-01-01

    The object G2 will pass within nearly 100 au from Sgr A* in 2014. Due to its very short periapse, the study of the dynamical evolution of this object in the short-term future may offer some insight into the region surrounding the supermassive black hole at the centre of the Galaxy. With this scenario in mind, it has recently been proposed by Bartos et al. (arXiv:1302.3220) that, prior to its perinigricon, G2 will likely experience multiple encounters with members of the black hole and neutron star populations believed to orbit near the Galactic Centre. Here, we further explore this possibility and study the general case for collisions with the G2 object using the latest orbital solutions provided by Phifer et al. (arXiv:1304.5280) and Gillessen et al., (arXiv:1306.1374) and a Monte Carlo approach to estimate the minimum orbit intersection distance (MOID) with G2 as a function of the orbital parameters of the incoming body. Our results indicate that encounters at distances closer than 100 au started to become ...

    The CERN Control Centre (CCC) is the nerve centre of the CERN beam systems. From this room, the experts prepare, monitor, adjust, and control the particle beams that circulate throughout the accelerator complex while ensuring that the services and the technical infrastructure work flawlessly. Buttons, screens, telephones, lights (but no sound): in the CCC, everything is ready to make it possible for the LHC to reach the unprecedented energies expected at Run 2.   Seen from above, the CERN Control Centre resembles the shape of a quadrupole magnet. The consoles are distributed in four circles, called “islands”, dedicated to the LHC, the SPS, the PS Complex and the Technical Infrastructure (TI) respectively. Spread between TI and LHC are the Cryogenics consoles. Being in the same room allows the 24h-manned islands to be constantly in touch with one another, thus ensuring the best performance of the machines. At the LHC island, operators are currently busy training the magnet...

  10. Medical applications in a nuclear research centre

    International Nuclear Information System (INIS)

    In these days of public aversion to nuclear power, it can be important to point at the medical applications of ionising radiation. Not only the general public, but also the authorities and research centres have to be aware of these medical applications, which are not without risk for public health. Now that funding for nuclear research is declining, an opening to the medical world can give new opportunities to a nuclear research centre. A lot of research could be done where the tools developed for the nuclear power world are very useful. Even new applications for the research reactors like BNCT (boron neutron capture therapy) can be envisaged for the near future. In this contribution an overview will be given of the different techniques used in the medical world with ionising radiation. The specific example of the Belgian Nuclear Research Centre will be given where the mission statement was changed to include a certain number of medical research topics. (authors)

  12. Optimizing Data Centre Energy and Environmental Costs

    Science.gov (United States)

    Aikema, David Hendrik

    Data centres use an estimated 2% of US electrical power which accounts for much of their total cost of ownership. This consumption continues to grow, further straining power grids attempting to integrate more renewable energy. This dissertation focuses on assessing and reducing data centre environmental and financial costs. Emissions of projects undertaken to lower the data centre environmental footprints can be assessed and the emission reduction projects compared using an ISO-14064-2-compliant greenhouse gas reduction protocol outlined herein. I was closely involved with the development of the protocol. Full lifecycle analysis and verifying that projects exceed business-as-usual expectations are addressed, and a test project is described. Consuming power when it is low cost or when renewable energy is available can be used to reduce the financial and environmental costs of computing. Adaptation based on the power price showed 10--50% potential savings in typical cases, and local renewable energy use could be increased by 10--80%. Allowing a fraction of high-priority tasks to proceed unimpeded still allows significant savings. Power grid operators use mechanisms called ancillary services to address variation and system failures, paying organizations to alter power consumption on request. By bidding to offer these services, data centres may be able to lower their energy costs while reducing their environmental impact. If providing contingency reserves which require only infrequent action, savings of up to 12% were seen in simulations. Greater power cost savings are possible for those ceding more control to the power grid operator. Coordinating multiple data centres adds overhead, and altering at which data centre requests are processed based on changes in the financial or environmental costs of power is likely to increase this overhead. Tests of virtual machine migrations showed that in some cases there was no visible increase in power use while in others power use

    2009-10-01

    A novel interfacial route has been developed for the synthesis of a bright-red-emitting new subnanocluster, Au(23), by the core etching of a widely explored and more stable cluster, Au(25)SG(18) (in which SG is glutathione thiolate). A slight modification of this procedure results in the formation of two other known subnanoclusters, Au(22) and Au(33). Whereas Au(22) and Au(23) are water soluble and brightly fluorescent with quantum yields of 2.5 and 1.3 %, respectively, Au(33) is organic soluble and less fluorescent, with a quantum yield of 0.1 %. Au(23) exhibits quenching of fluorescence selectively in the presence of Cu(2+) ions and it can therefore be used as a metal-ion sensor. Aqueous- to organic-phase transfer of Au(23) has been carried out with fluorescence enhancement. Solvent dependency on the fluorescence of Au(23) before and after phase transfer has been studied extensively and the quantum yield of the cluster varies with the solvent used. The temperature response of Au(23) emission has been demonstrated. The inherent fluorescence of Au(23) was used for imaging human hepatoma cells by employing the avidin-biotin interaction.

    CERN Document Server

    Schenke, Bjoern; Venugopalan, Raju

    2014-01-01

    We study within the IP-Glasma and two-component MC-Glauber models the effects of initial state geometry and fluctuations on multiplicities and eccentricities for several collision species at the Relativistic Heavy Ion Collider (RHIC). These include copper-gold (Cu+Au), gold-gold (Au+Au), and uranium-uranium (U+U) collisions. The multiplicity densities per participant pair are very similar in all systems studied. Ellipticities vary strongly between collision systems, most significantly for central collisions, while fluctuation driven odd moments vary little between systems. Event-by-event distributions of eccentricities in mid-central collisions are wider in Cu+Au relative to Au+Au and U+U systems. An anti-correlation between multiplicity and eccentricity is observed in ultra central U+U collisions which is weaker in the IP-Glasma model than the two-component MC-Glauber model. In ultra central Au+Au collisions the two models predict opposite signs for the slope of this correlation. Measurements of elliptic flo...

The information is given both visually - with excerpts from some of the attractions on display at the centres - and in comments from interviews with visitors, the centre guides and the man responsible for many of the exhibits featured in the video. on one side are the schoolchildren who are visiting the exhibition and are seen both playing and learning as they press buttons, watch videos, 'meet' Michael Faraday, and learn about radiation - its disposal and its safe transportation. The headmaster of the school is interviewed and explains that the exhibition is helping his children understand the importance of electricity to their world. on the other side is Jackie Lucas, the visitor centre manager, explaining what the public make of the exhibition. We see her staff greeting the children and helping them to understand the show.

  2. Person-centred care in nursing documentation.

    LENUS (Irish Health Repository)

    Broderick, Margaret C

    2012-12-07

    BACKGROUND: Documentation is an essential part of nursing. It provides evidence that care has been carried out and contains important information to enhance the quality and continuity of care. Person-centred care (PCC) is an approach to care that is underpinned by mutual respect and the development of a therapeutic relationship between the patient and nurse. It is a core principle in standards for residential care settings for older people and is beneficial for both patients and staff (International Practice Development in Nursing and Healthcare, Chichester, Blackwell, 2008 and The Implementation of a Model of Person-Centred Practice in Older Person Settings, Dublin, Health Service Executive, 2010a). However, the literature suggests a lack of person-centredness within nursing documentation (International Journal of Older People Nursing 2, 2007, 263 and The Implementation of a Model of Person-Centred Practice in Older Person Settings, Dublin, Health Service Executive, 2010a). AIMS AND OBJECTIVES: To explore nursing documentation in long-term care, to determine whether it reflected a person-centred approach to care and to describe aspects of PCC as they appeared in nursing records. METHOD: A qualitative descriptive study using the PCN framework (Person-centred Nursing; Theory and Practice, Oxford, Wiley-Blackwell, 2010) as the context through which nursing assessments and care plans were explored. RESULTS: Findings indicated that many nursing records were incomplete, and information regarding psychosocial aspects of care was infrequent. There was evidence that nurses engaged with residents and worked with their beliefs and values. However, nursing documentation was not completed in consultation with the patient, and there was little to suggest that patients were involved in decisions relating to their care. IMPLICATIONS FOR PRACTICE: The structure of nursing documentation can be a major obstacle to the recording of PCC and appropriate care planning. Documentation

    Full Text Available L’olivier est une culture traditionnelle sur le pourtour de la Méditerranée. Il est donc naturel de trouver cet arbre au Maroc où il est présent depuis des siècles. Cultivé surtout traditionnellement jusqu’à ses dernières années, il fait l’objet maintenant d’un plan de valorisation très ambitieux pour non seulement garder le Royaume à son niveau actuel (2e producteur mondial pour l’olive de conserve et 6e pour l’huile d’olive mais pour conquérir de nouveaux marchés au niveau mondial et profiter ainsi de l’engouement que connaît cette huile reconnue pour ses bienfaits. Le plan national « Maroc Vert » permet ainsi, grâce à des subventions conséquentes, non seulement de renouveler les vergers existant avec la variété traditionnelle picholine du Maroc, mais également la plantation de nouvelles variétés en super-intensif dans le but d’industrialiser au maximum de nouveaux vergers. Il en est de même pour la transformation des olives en huile de bonne qualité avec la mise en place d’unités de trituration modernes qui doivent supplanter à terme la multitude de « maâsra » et réduire ainsi l’impact environnemental dû aux margines. L’olive ne sera plus dans l’avenir que représentée par son huile et ses formes comestibles, mais les résidus de son extraction seront valorisés soit sous forme de combustible élaboré pour le grignon, soit sous forme d’une base de chimie verte pour les sous-produits du raffinage. D’autres applications sont actuellement à l’étude, car le Maroc à compris, comme tous les autres grands pays producteurs, que l’olive était un nouveau gisement de richesses.

  7. Antiproton Production in Au+Au Collisions at 11.7a GeV/c

    International Nuclear Information System (INIS)

    Antiproton production in 11.7A GeV/c Au+Au collisions over a wide transverse-mass coverage was studied using the AGS-E866 experimental apparatus. The mean transverse kinetic energy increases as a function of centrality and is similar to that of protons. The antiproton yields in Si+Al , Si+Au , and Au+Au collisions are consistent with scaling with the 0.7 power of the number of participant nucleons. Copyright 1998, The American Physical Society

    The eccentricity of the centre of mass from the geometric centre of a spherical attracting mass in determining the Newtonian gravitational constant G is tested by means of an electronic balance. The experimental result shows that the eccentricity of the sample is about 0.31 μm with uncertainty of 0.05 μm. Two density distribution models are discussed to estimate the uncertainty to G by the eccentricities of the attracting masses.

  11. Strain distributions of confined Au/Ag and Ag/Au nanoparticles

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    The strain distributions of Au/Ag and Ag/Au nanoparticles confined in the Al2O3 matrix with different core sizes are investigated by using the finite element method, respectively. The simulation results clearly indicate that the compressive strains exerted on the Au/Ag and Ag/Au nanoparticles can be induced by the Al2O3 matrix. Moreover, it can be found that the strain gradient existing in a Au/Ag nanoparticle is much larger than that in a Ag/Au nanoparticle, which could be due to the larger Young’s modulus of Au than that of Ag. With the core size increasing, the strain gradient existing in the Au/Ag nanoparticle becomes larger, while the strain gradient existing in the Ag/Au nanoparticle keeps constant. These different strain distributions may have significant infl uences on the structures and morphologies of the Au/Ag and Ag/Au nanoparticles, leading to the different physical properties for potential applications.

    M. Vinod; K.G.Gopchandran

    2014-01-01

    Chemically pure colloidal suspensions of gold and silver nanoparticles were synthesized using pulsed laser ablation. The dependence of laser fluence on the surface plasmon characteristics of the nanoparticles was investigated. Au:Ag colloidal suspensions were prepared by mixing highly monodisperse Au and Ag nanocolloids. The plasmon band of these mixtures was found to be highly sensitive to Au:Ag concentration ratio and wavelength of the laser beam used in the ablation process. The Au:Ag mixture consists of almost spherical shaped nanostructures with a tendency to join with adjacent ones. The surface enhanced Raman scattering activity of the Au, Ag and Au:Ag colloidal suspensions was tested using crystal violet as probe molecules. Enhancement in Raman signal obtained with Au:Ag substrates was found to be promising and strongly depends on its plasmon characteristics.

L’importance de la fonction de gestion des ressources humaines est déterminante dans le succès des opérations de changement. La mobilisation des énergies au bénéfice d’un but commun reste un souci essentiel des dirigeants. L’encouragement et la valorisation de comportements méritants est au cœur des réflexions. Des stratégies méritocratiques diverses sont envisagées. Elles ne peuvent cependant être développées en dehors des aspects liés à la motivation au travail.

The patient-centred approach (and related concepts: patient participation, involvement, and empowerment) is being promoted both in healthcare politics and by healthcare professionals as a way to achieve more active self-managing and self-caring patients. Patient......-centredness is thus promoted as a way to organize health more effectively (in terms of cost and treatment outcomes) and as a way to ensure patients’ autonomy and fundamental right to make their own decisions regarding their treatment.

The construction work has already begun and is due to be completed in October 2012.   Every year CERN experiences around ten power cuts lasting from less than a second to several hours. In most cases the two protection systems - the UPS* and the diesel generators – are able to ensure that the operation of the Computer Centre is not affected. As Vincent Doré, the project leader for the IT Department, and Paul Pepinster, the EN Department's technical coordinator in charge of modernising the infrastructure, explains: "Building 513 has two types of computing facilities – the "non-critical" ones, such as the servers for "off-line" computing, which have UPS systems ensuring that they can operate for 10 minutes after a power cut, and the "critical&...

    Full Text Available Techniquest was established in 1986, and in 1995 moved to its current premises at Cardiff Bay, South Wales. This was the first purpose-built science centre in the UK. It receives around 200,000 visitors every year to its exhibition, and to its programmes for schools and public audiences in the theatre, laboratory, discovery room and planetarium. The author joined the Techniquest project in 1985, became a staff member in 1990 and was the Chief Executive from 1997 until his retirement in 2004. Techniquest has three “out-stations” in Wales, and is responsible for the supply and maintenance of exhibits to the Look Out Discovery Centre in Bracknell, England. There is a Techniquest gallery at the Lisbon Pavilhão do Conhecimento - Ciência Viva, and a traveling exhibition, SciQuest, in South Africa which was also supplied by Techniquest. All these centres rely on the effective intervention of “Explainers” (at Techniquest we call them “Helpers” to provide the best possible experience for visitors. At its most demanding, the tasks of an Explainer are varied and intensive, yet there may be times when the duties are mundane or even dull. When you rely on people to act as both hosts and housekeepers, to provide both support and stimulus, and to be both welcoming and watchful, you are asking a great deal. This article raises some of the issues concerned with the recruitment and retention of Explainers, their training and management, and the way in which their role is recognized and valued by the science centre as a whole.

  11. Bismuth centred magnetic perovskite: A projected multiferroic

    International Nuclear Information System (INIS)

    In recent time substantial attention has been initiated to understand the physics behind multiferroism and to design new multiferroic materials. BiMnO3 and BiFeO3 are the well-studied Bi-centred multiferroic oxides. BiMnO3 is a ferromagnetic–ferroelectric (metastable) phase and require drastic conditions to synthesize. However, lanthanum substituted BiMnO3 phases stabilized at ambient pressure. It is thus of major importance to increase the number of ferromagnetic perovskites with Bi cations that could be designed under ambient conditions. In this article, we have presented an up to date report of investigations on Bi-centred magnetic perovskites, a prospective material for multiferroic application. Central focus is concentrated on La0.5Bi0.5MnO3 perovskite with various substitutions at different levels. A few of these perovskites are found to be of practical importance e.g. La0.5Bi0.5Mn0.67Co0.33O3 with high dielectric permittivity coupled with ferromagnetism. A comprehensive analysis of different physical functionalities and their interrelation for a wide range of compositions of these Bi-centred perovskites is presented. It has been found that the complex magnetic behaviour originates from mixed valence metal ions. The ferroelectricity is associated with the 6s2 lone pair of Bi3+ cations. The magnetic ground state influences the dielectric properties reflecting the multiferroism in a single material. - Highlights: • Multiferroics have attracted increasing attention due to their possible device applications. • Bismuth centred magnetic perovskite is one kind of such promising multiferroic materials. • Ferromagnetic Bi-perovskites, which are synthesized at ambient conditions, have been discussed

    2001-01-01

    At the inauguration of the new CMS visitor centre. The CMS experiment inaugurated a new visitor centre at its Cessy site on 14 June. This will allow the thousands of people who come to CERN each year to follow the construction of one the Laboratory's flagship experiments first-hand. CERN receives over 20,000 visitors each year. Until recently, many of them were taken on a guided tour of one of the LEP experiments. With the closure of LEP, however, trips underground are no longer possible, and the Visits' Service has put in place a number of other itineraries (Bulletin 46/2000). Since the CMS detector will be almost entirely constructed in a surface hall, it is now taking a big share of the limelight. The CMS visitor centre has been built on a platform overlooking CMS construction. It contains a set of clear descriptive posters describing the experiment, along with a video projection showing animations and movies about CMS construction. In the coming weeks, a display of CMS detector elements will be added, as...

  4. Gamma Rays frim the Galactic Centre

    Erlykin, A D

    2007-01-01

    Recent results from the HESS gamma ray telescope have shown the presence of both a diffuse, extended, flux of gamma rays above ~0.4 TeV and discrete sources in and near the Galactic Centre. Here, we put forward a possible explanation in terms of the diffusion of cosmic ray protons from a succession of supernova remnants (SNR) in the SgrA* region of the Galaxy plus a contribution from SNR in the rest of the Galactic Centre Region, to be called the Galactic Centre Ridge (GCR). Protons are favoured over electrons because the mG magnetic fields in the Region will attenuate energetic electrons severely. Prominent features are the need for 'anomalous diffusion' of the protons in the whole region and the adoption of low efficiency for SNR acceleration in the high density regions. The latter is related by us to the well-known low 'cosmic ray gradient' in the Galaxy. A corroborating feature is the close correlation of inferred cosmic ray intensity with the smoothed intensity of 5 GHZ radio radiation. We attribute this...

  8. IAEA establishes International Seismic Safety Centre

    International Nuclear Information System (INIS)

    Full text: The IAEA today officially inaugurated an international centre to coordinate efforts for protecting nuclear installations against the effects of earthquakes. The International Seismic Safety Centre (ISSC), which has been established within the IAEA's Department of Nuclear Safety and Security, will serve as a focal point on seismic safety for nuclear installations worldwide. ISSC will assist countries on the assessment of seismic hazards of nuclear facilities to mitigate the consequences of strong earthquakes. 'With safety as our first priority, it is vital that we pool all expert knowledge available worldwide to assist nuclear operators and regulators to be well prepared for coping with major seismic events,' said Antonio Godoy, Acting Head of the IAEA's Engineering Safety Section and leader of the ISSC. 'The creation of the ISSC represents the culmination of three decades of the IAEA's active and recognized involvement in this matter through the development of an updated set of safety standards and the assistance to Member States for their application.' To further seismic safety at nuclear installations worldwide, the ISSC will: - Promote knowledge sharing among the international community in order to avoid or mitigate the consequences of extreme seismic events on nuclear installations; - Support countries through advisory services and training courses; and - Enhance seismic safety by utilizing experience gained from previous seismic events in member states. The centre is supported by a scientific committee of high-level experts from academic, industrial and nuclear safety authorities that will advise the ISSC on implementation of its programme. Experts have been nominated from seven specialized areas, including geology and tectonics, seismology, seismic hazard, geotechnical engineering, structural engineering, equipment, and seismic risk. Japan and the United States have both contributed initial funds for creation of the centre, which will be based at

    Full Text Available Patient-centred design is a relatively new term, but a longstanding concept in clinical practice. This discussion looks at patient-centred design and explores the relationships of patient-centred design to universal design, user-centred design and the newer human-centred design. It also explores why interdisciplinary approaches are needed for patient-centred design and how interdisciplinary collaboration works to address the challenges of patient centred design. Successful patient-centred solutions can grow from collaborations which include shared visions, understanding of both the nature and degree of variation in the patient,materials, and the designed solution, clear regular communication among all parties with careful definition of terms, and respect for the inherent cultures of all disciplines involved.

    Heptamethinecyanine J-aggregates display sharp, intense fluorescence emission making them attractive candidates for developing a variety of chem-bio-sensing applications. They have been immobilized on planar thiol-covered Au surfaces and thiol-capped Au nanoparticles by weak molecular interactions. In this work the self-assembly of novel thiolated cyanine (CNN) on Au(111) and citrate-capped AuNPs from solutions containing monomers and J-aggregates has been studied by using STM, XPS, PM-IRRAS, electrochemical techniques and Raman spectroscopy. Data show that CNN species adsorb on the Au surfaces by forming thiolate-Au bonds. We found that the J-aggregates are preferentially adsorbed on the Au(111) surface directly from the solution while adsorbed CNN monomers cannot organize into aggregates on the substrate surface. These results indicate that the CNN-Au interaction is not able to disorganize the large J-aggregates stabilized by π-π stacking to optimize the S-Au binding site but it is strong enough to hinder the π-π stacking when CNNs are chemisorbed as monomers. The optical properties of the J-aggregates remain active after adsorption. The possibility of covalently bonding CNN J-aggregates to Au planar surfaces and Au nanoparticles controlling the J-aggregate/Au distance opens a new path regarding their improved stability and the wide range of biological applications of both CNN and AuNP biocompatible systems.Heptamethinecyanine J-aggregates display sharp, intense fluorescence emission making them attractive candidates for developing a variety of chem-bio-sensing applications.

  12. Controlled Synthesis of Au@AgAu Yolk-Shell Cuboctahedra with Well-Defined Facets.

    2016-08-01

    The synthesis of Au@AgAu yolk-shell cuboctahedra nanoparticles formed by galvanic replacement in a seed-mediated method is described. Initially, single-crystal Au seeds are used for the formation of Au@Ag core-shell nanocubes, which serve as the template material for the deposition of an external Au layer. The well-controlled synthesis yields the formation of cuboctahedra nanoparticles with smooth inner and outer Au/Ag surfaces. The deposition/oxidation process is described to understand the formation of cuboctahedra and octahedra nanoparticles. The Au core maintains the initial morphology of the seed and remains static at the center of the yolk-shell because of residual Ag. Structural analysis of the shell indicates intrinsic stacking faults (SFs) near the surface. Energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) compositional analysis show an Au-Ag nonordered alloy forming the shell. The three-dimensional structure of the nanoparticles presented open facets on the [111] as observed by electron tomography SIRT reconstruction over a stack of high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) images. The geometrical model was validated by analyzing the direction of streaks in coherent nanobeam diffraction (NBD). The catalytic activity was evaluated using a model reaction based on the reduction of 4-nitrophenol (4-NTP) by NaBH4 in the presence of Au@AgAu yolk-shell nanoparticles. PMID:27385583

    article argues that, despite this critique, au pairing does play an important formative role for young Filipinas because it opens up for experiences abroad that enable them to be recognised as independent adults in Philippine society. Rather than autonomy, however, au pairs define their independence in...... terms of their capacity to assume responsibility for others, thereby achieving a position of social respect. Based on ethnographic fieldwork in Denmark and the Philippines, this article explores how young Filipinas use the social, economic, and cultural resources they gain from their au pair stay abroad...

  1. Synthesis of ultrathin face-centered-cubic Au@Pt and Au@Pd core-shell nanoplates from hexagonal-close-packed Au square sheets

    KAUST Repository

    Fan, Zhanxi

    2015-03-17

    The synthesis of ultrathin face-centered-cubic (fcc) Au@Pt rhombic nanoplates is reported through the epitaxial growth of Pt on hexagonal-close-packed (hcp) Au square sheets (AuSSs). The Pt-layer growth results in a hcp-to-fcc phase transformation of the AuSSs under ambient conditions. Interestingly, the obtained fcc Au@Pt rhombic nanoplates demonstrate a unique (101)f orientation with the same atomic arrangement extending from the Au core to the Pt shell. Importantly, this method can be extended to the epitaxial growth of Pd on hcp AuSSs, resulting in the unprecedented formation of fcc Au@Pd rhombic nanoplates with (101)f orientation. Additionally, a small amount of fcc (100)f-oriented Au@Pt and Au@Pd square nanoplates are obtained with the Au@Pt and Au@Pd rhombic nanoplates, respectively. We believe that these findings will shed new light on the synthesis of novel noble bimetallic nanostructures. Phase change: Ultrathin Au@Pt and Au@Pd core-shell nanoplates were prepared from Au square sheets. A phase transformation from hexagonal close-packed (hcp) to face-centered cubic (fcc) is observed upon coating the hcp Au square sheets with Pt or Pd under ambient conditions. The prepared fcc Au@Pt and Au@Pd rhombic nanoplates demonstrate unique (101)f orientation (picture shows a typical fcc Au@Pt rhombic nanoplate). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The photoluminescence characteristics of Au(0)@Au(I)-thiolate Core–shell nanoclusters (Au-NCs), whose size is <2 nm, are investigated. We use the time-resolved single-photon counting technique and the transient absorption technique to distinguish the mechanism of the photoluminescence of Au-NCs. The dynamic spectral data show that the photoluminescence mechanism should be composed of the fluorescence and the phosphorescence. Meanwhile, Au-NCs have the aggregation induced photoluminescence enhancement property, which is attributed to the suppression of conversion from the singlet state to triplet state when they aggregated together. In addition, the photoluminescence characteristics of aggregated Au-NCs should be further improved through infiltrating them into photonic crystals.

  5. A comparative study of Ge/Au/Ni/Au-based ohmic contact on graphene

    International Nuclear Information System (INIS)

    Superior graphene—metal contacts can improve the performance of graphene devices. We report on an experimental demonstration of Ge/Au/Ni/Au-based ohmic contact on graphene. The transfer length method (TLM) is adopted to measure the resistivity of graphene-metal contacts. We designed a process flow, which can avoid residual photoresist at the interface of metal and graphene. Additionally, rapid thermal annealing (RTA) at different temperatures as a post-processing method is studied to improve graphene—metal contact. The results reveal that the contact resistivity of graphene and Ge/Au/Ni/Au can reach 10−5 Ω·cm2 after RTA, and that 350 °C is optimum annealing temperature for the contact of graphene—Ge/Au/Ni/Au. This paper provides guidance for fabrication and applications of graphene devices. (semiconductor technology)

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at sqrt(s_NN) = 200 GeV. The evolution of the spectra for transverse momenta p_T from 0.25 to 5GeV/c is studied as a function of collision centrality over a range from 65 to 344 participating nucleons. We find a significant change of the spectral shape between proton-antiproton and peripheral Au+Au collisions. Comparing peripheral to central Au+Au collisions, we find that the yields at the highest p_T exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

    The Norwegian Centre for Addiction Research (SERAF) at the University of Oslo is a newly established, clinical addiction research centre. It is located at the Oslo University Hospital and has a major focus on opioid dependency, investigating Norwegian opioid maintenance treatment (OMT), with special interest in OMT during pregnancy, mortality, morbidity and criminality before, during and after OMT and alternatives to OMT, such as the use of naltrexone implants. The well-developed health registries of Norway are core assets that also allow the opportunity for other types of substance abuse research. This research includes health services, abuse of prescription drugs and drugs of abuse in connection with traffic. The centre also focuses upon comorbidity, investigating the usefulness and limitations of psychometric instruments, drug abuse in different psychiatric treatment settings and internet-based interventions for hazardous alcohol consumption.

    Three Au-based nanomaterials (silica@Au nanoshells, hollow Au/Ag nanospheres and Au nanorods) were evaluated for their comparative photothermal efficiencies at killing three types of malignant cells (A549 lung cancer cells, HeLa cervix cancer cells and TCC bladder cancer cells) using a CW NIR laser. Photodestructive efficiency was evaluated as a function of the number of nanoparticles required to destroy the cancer cells under 808 nm laser wavelength at fixed laser power. Of the three nanomaterials, silica@Au nanoshells needed the minimum number of particles to produce effective photodestruction, whereas Au nanorods needed the largest number of particles. Together with the calculated photothermal conversion efficiency, the photothermal efficiency rankings are silica@Au nanoshells > hollow Au/Ag nanospheres > Au nanorods. Additionally, we found that HeLa cells seem to present better heat tolerance than the other two cancer cell lines.

    A number of human-centred methodologies—subjective, objective, and combined—are used for slipperiness measurement. They comprise a variety of approaches from biomechanically-oriented experiments to psychophysical tests and subjective evaluations. The objective of this paper is to review some of the research done in the field, including such topics as awareness and perception of slipperiness, postural and balance control, rating scales for balance, adaptation to slippery conditions, measurement of unexpected movements, kinematics of slipping, and protective movements during falling. The role of human factors in slips and falls will be discussed. Strengths and weaknesses of human-centred approaches in relation to mechanical slip test methodologies are considered. Current friction-based criteria and thresholds for walking without slipping are reviewed for a number of work tasks. These include activities such as walking on a level or an inclined surface, running, stopping and jumping, as well as stair ascent and descent, manual exertion (pushing and pulling, load carrying, lifting) and particular concerns of the elderly and mobility disabled persons. Some future directions for slipperiness measurement and research in the field of slips and falls are outlined. Human-centred approaches for slipperiness measurement do have many applications. First, they are utilized to develop research hypotheses and models to predict workplace risks caused by slipping. Second, they are important alternatives to apparatus-based friction measurements and are used to validate such methodologies. Third, they are used as practical tools for evaluating and monitoring slip resistance properties of foot wear, anti-skid devices and floor surfaces. PMID:11794763

  13. Electrical conduction through self-assembled monolayers in molecular junctions: Au/molecules/Au versus Au/molecule/PEDOT:PSS/Au

    International Nuclear Information System (INIS)

    We fabricated and characterized a large number of octanedithiol (denoted as DC8) molecular devices as vertical metal-molecule-metal structure with or without using an intermediate conducting polymer layer of poly (3,4-ethylenedioxythiophene) stabilized with poly(4-styenesulfonic acid) (called as PEDOT:PSS). The electronic transport properties of DC8 molecular devices with and without PEDOT:PSS layer were statistically compared in terms of current density and device yield. The yields of the working molecular devices were found to be ∼ 1.75% (84 out of 4800 devices) for Au/DC8/Au junctions and ∼ 58% (74 out of 128 devices) for Au-DC8/PEDOT:PSS/Au junctions. The tunneling decay constants were obtained with the Simmons tunneling model and a multibarrier tunneling model for two kinds of molecular devices with and without PEDOT:PSS layer.

    measurements based on OAE suppression techniques and notched-noise masking data psychophysically measured for centre frequencies in the range 50-125 Hz, this study examines how individual differences in frequency selectivity, as well as in masking, may occur at very low CFs due to individual differences in the...... shape of the METFs, thought to be affected by the helicotrema impedance. Preliminary analysis indicates that individual differences in the METFs might underlay the observed individual differences in frequency selectivity. Main effects predicted by the calculations are a pronounced flattening off of the...

    The ‘impact’ of research has seen a dramatic rise up the UK’s policy agenda in recent years. But what does ‘impact’ really mean? How do researchers and others respond to the new ‘impact agenda’ and how might we best plan, monitor and report on impact? This working paper attempts to provide answers to some of these questions by reviewing various understandings of ‘impact’ and describing the approach used by the ESRC STEPS Centre in its second five-year phase of funding. In particular, we draw ...

  17. Hunting for hardware changes in data centres

    International Nuclear Information System (INIS)

    With many servers and server parts the environment of warehouse sized data centres is increasingly complex. Server life-cycle management and hardware failures are responsible for frequent changes that need to be managed. To manage these changes better a project codenamed “hardware hound” focusing on hardware failure trending and hardware inventory has been started at CERN. By creating and using a hardware oriented data set - the inventory - with detailed information on servers and their parts as well as tracking changes to this inventory, the project aims at, for example, being able to discover trends in hardware failure rates.

  19. Proton channeling in Au at low energies

    International Nuclear Information System (INIS)

    The electronic energy loss for low velocity protons channeled in the direction single crystal Au is calculated. The spatial distribution of valence electronic density in Au is calculated using Tight Binding Linear Muffin Tin Method. The proton trajectories are determined by numerical integration of the classical motion equation, and the energy loss is evaluated using the calculated valence electronic density in the friction term. The results allow to describe qualitatively the non linear behavior of energy loss with ion velocity observed experimentally. (author)

    Highlights: •Gold “crop circles” after annealing Au thin films deposited onto native silicon oxide. •Morphological and IBA analysis confirms the model proposed by Matthews et al. [1]. •The shape of the Au central polygon is determined by the Si orientation. -- Abstract: When a thin gold layer is deposited onto the native oxide of a silicon wafer and is annealed at temperatures greater than 600 °C, peculiar circular features, few micrometers in diameter, with a regular polygon at the centre of each circle, reminiscent of so called “alien” crop circles, can be observed. A model has been recently proposed in Matthews et al. [1], where the formation of such circular structures is attributed to the interdiffusion of gold and silicon through holes in the native oxide induced by the weakening of the amorphous silica matrix occurring during the annealing process. The rupture of the liquid Au/Si eutectic disc surrounding the pinhole in the oxide causes the debris to be pulled to the edges of the disk, forming Au droplets around it and leaving an empty zone of bare silicon oxide. In this paper, we present a morphological study and a RBS/PIXE analyses of these circular structures, carried out by scanning electron microscopy and by 4 MeV C microbeam, respectively. The results confirm the depletion of gold in the denuded circular zones, and the presence of gold droplets in the centers, which can be attributed to the Au segregation occurring during the cooling stage.

These measurements suggest a large energy loss of the high-pT particles in the highly interacting medium created in the central Au + Au collisions. The lack of suppression in d + Au collisions suggests that it is unlikely that initial state effects can explain the suppression in the central Au + Au collisions. PACS: 25.75.-q

  4. The Australian centre for RF bioeffects research (ACRBR) - an NHMRC centre of research excellence

    International Nuclear Information System (INIS)

    Full text: The Australian Centre for Radiofrequency Bioeffects Research (ACRBR) is a newly established multi-institutional research centre which seeks to research questions pertaining to possible health effects of exposure to radiofrequency devices, such as mobile phones and which is funded under the Australian National Health and Medical Research Council (NHMRC) Centres of Research Excellence funding program. The Centre of Research Excellence in Electromagnetic Energy is combining the efforts of engineers, epidemiologists, physicists, psychophysiologists and veterinary pathologists from RMIT University, the Institute of Medical and Veterinary Science in South Australia (IMVS), Monash University, Swinburne University of Technology and Telstra Research Laboratories (TRL). The centre is funded at $2.5 M over five years and will undertake a program of research to address the issue of exposure to radiofrequency (RF) devices and health. It will also train new scientists, keep the community informed of ongoing developments and help the development of government policies in this area of considerable public concern. The 5-year program has the following components: Neurobiology: One important area where there is a perceived research gap is in the area of potential neurological effects, which will hence be a major focus of this Centre. The proposed studies range from in vitro and in vivo research studies of RF effects on neuron and neural system functioning in rodents, to that of RF effects on simple neural function, cognition and subjective report in humans. The latter series of studies have been developed to account for the consensus view that more emphasis needs to be placed on possible differences in RF population sensitivity (e.g. youth versus aged, and ' electromagnetic hypersensitives'). Epidemiological studies are an important tool in studying the impact on public health from exposure of whole populations to modern radio technologies. Cancer outcomes in this area of

    Identified charged-particle spectra of π±, K±, p, and pmacr at midrapidity (|y|<0.1) measured by the dE/dx method in the STAR (solenoidal tracker at the BNL Relativistic Heavy Ion Collider) time projection chamber are reported for pp and d+Au collisions at sNN=200 GeV and for Au+Au collisions at 62.4, 130, and 200 GeV. Average transverse momenta, total particle production, particle yield ratios, strangeness, and baryon production rates are investigated as a function of the collision system and centrality. The transverse momentum spectra are found to be flatter for heavy particles than for light particles in all collision systems; the effect is more prominent for more central collisions. The extracted average transverse momentum of each particle species follows a trend determined by the total charged-particle multiplicity density. The Bjorken energy density estimate is at least several GeV/fm3 for a formation time less than 1 fm/c. A significantly larger net-baryon density and a stronger increase of the net-baryon density with centrality are found in Au+Au collisions at 62.4 GeV than at the two higher energies. Antibaryon production relative to total particle multiplicity is found to be constant over centrality, but increases with the collision energy. Strangeness production relative to total particle multiplicity is similar at the three measured RHIC energies. Relative strangeness production increases quickly with centrality in peripheral Au+Au collisions, to a value about 50% above the pp value, and remains rather constant in more central collisions. Bulk freeze-out properties are extracted from thermal equilibrium model and hydrodynamics-motivated blast-wave model fits to the data. Resonance decays are found to have little effect on the extracted kinetic freeze-out parameters because of the transverse momentum range of our measurements. The extracted chemical freeze-out temperature is constant, independent of collision system or centrality; its value is close

    Au, Pt and Au-Pt alloy nanocrystals have been prepared in thin SiO2 film matrices by sol-gel spin-coating, followed by heating at 450 uC in 10% $H_{2}$-90% Ar. X-Ray diffraction patterns reveal that the Au and Au-Pt nanocrystals have a preferential (111) orientation. Upon increasing the Pt concentration, part of the Pt does not alloy with Au, but instead forms a shell around the Au-Pt alloy core. The alloy composition itself goes up to Au(50) : Pt(50), and the Pt shells are formed around the ...

  7. Information validation tool for technical support centres

    International Nuclear Information System (INIS)

    The French National Emergency Organisation relies on the expert advice given by the different Technical Support Centres (EDF/SEPTEN, CEA/IPSN, Framatome). For several years a great effort has been made to improve tools. The first generation was mainly concerned with computational aids such as real-time plant data acquisition and visualisation, break size calculations, containment release estimations... These tools were presented at the OECD NEA Specialist Meeting in 1993. Currently work is performed in the field of validation of information available to the Technical Support Centres. The three partners (EDF, CEA and Framatome) have developed a prototype implementing the diagnosis and the quality of the information pertaining to the 3D/3P method. The philosophy of this tool is to present to the expert a set of essential information (e.g. state of the fuel barrier, primary water inventory...) for the diagnosis with a confidence level associated to each information and the adequate explications. In fact the expert has not only to know the diagnosis but also how reliable the information is and why. Subsequently, the algorithms used to elaborate the diagnoses and the confidence factor have to be simple enough so that the user is able to consult the explanations in a fast and easy way. The paper details the three-step process to elaborate the diagnosis and the confidence factor

    KNMI is the Dutch institute for weather, climate research and seismology. It disseminates weather information to the public at large, the government, aviation and the shipping industry in the interest of safety, the economy and a sustainable environment. To gain insight into long-term developments KNMI conducts research on climate change. Making the knowledge, data and information on hand at KNMI accessible is one core activity. A huge part of the KNMI information is from numerical models, insitu sensor networks and remote sensing satellites. This digital collection is mostly internal only available and is a collection of non searchable , non standardized file formats, lacking documentation and has no references to scientific publications. With the KNMI Data Centre (KDC) project these issues are tackled. In the project a user driven development approach with SCRUM was chosen to get maximum user involvement in a relative short development timeframe. Building on open standards and proven open source technology (which includes in-house developed software like ADAGUC WMS and Portal) resulted in a first release in December 2012 This presentation will focus on the aspects of KDC relating to its technical challenges, the development strategy and the initial usage results of the data centre.

    Kanitz, J; Birken, B; Ward, V

    1982-01-01

    During the past two years, a multi-discipline health team has been meeting with selected diabetic "problem" patients on a regular basis at the North York General Hospital (NYGH). The patients are referred to the programme by their physicians when they appear to be having difficulty handling or coping with their diabetes. The participants in the programme attend the Diabetic Education Centre (DEC) for one week as day patients in the hospital and are exposed to various types of counselling from members of the Diabetic Education Centre Team (DECT), one of which is the pharmacist. Follow-up from this week of intensive education is made at annual intervals. The main purpose of the pharmacist in the clinic is to provide information for the patients regarding their prescriptions and over the counter (OTC) medication. This is achieved by means of individual patient interviews and informal group discussions, as well as rounds with other team members and contact with patients' families. This programme provides a forum for the patient and the patient's family to obtain valid information about diabetes, as well as problems associated with the disease, and aids in coping with these problems. The team concept enables the patient to be analyzed by all disciplines in order to assess his teaching needs and fulfill them. The pharmacist is continually involved in this information system and plays a valuable role on the team. PMID:10257341

  11. CMS tracker slides into centre stage

    CERN Multimedia

    2006-01-01

    As preparations for the magnet test and cosmic challenge get underway, a prototype tracker has been carefully inserted into the centre of CMS. The tracker, in its special platform, is slowly inserted into the centre of CMS. The CMS prototype tracker to be used for the magnet test and cosmic challenge coming up this summer has the same dimensions -2.5 m in diameter and 6 m in length- as the real one and tooling exactly like it. However, the support tube is only about 1% equipped, with 2 m2 of silicon detectors installed out of the total 200 m2. This is already more than any LEP experiment ever used and indicates the great care needed to be taken by engineers and technicians as these fragile detectors were installed and transported to Point 5. Sixteen thousand silicon detectors with a total of about 10 million strips will make up the full tracker. So far, 140 modules with about 100 000 strips have been implanted into the prototype tracker. These silicon strips will provide precision tracking for cosmic muon...

  13. Enhancing Communication in an Egyptian Research Centre

    International Nuclear Information System (INIS)

    This paper is a proposed attempt to enhance communication in a research centre in Egypt. The currently Nuclear and Radiological Regulatory Authority (NRRA) which formerly was the National Centre for Nuclear Safety and Radiation Control (NCNSRC) is housed in a nine-storey building with a straight double loaded corridor architectural plan. Syntactic axial analysis showed high integration for each floor plan individually which means that the floor plan is not to be blamed for lack of communication among floor inhabitants; other means must be attempted. But global axial integration (for the whole building) proved to be poor. A problem of communication among floors was identified. Means for enhancing communication were introduced: The lecture hall, the cafe and meeting rooms can play an important role in enhancing global communication among NRRA inhabitants. Besides a questionnaire was designed and distributed on all inhabitants and its feedback came up with ideas which if implemented could result in enhancing the level of communication between the inhabitants of the building thus overcoming spatial hindrances.

    Synthetic biology promises to create high-impact solutions to challenges in the areas of biotechnology, human/animal health, the environment, energy, materials and food security. Equally, synthetic biologists create tools and strategies that have the potential to help us answer important fundamental questions in biology. Warwick Integrative Synthetic Biology (WISB) pursues both of these mutually complementary 'build to apply' and 'build to understand' approaches. This is reflected in our research structure, in which a core theme on predictive biosystems engineering develops underpinning understanding as well as next-generation experimental/theoretical tools, and these are then incorporated into three applied themes in which we engineer biosynthetic pathways, microbial communities and microbial effector systems in plants. WISB takes a comprehensive approach to training, education and outreach. For example, WISB is a partner in the EPSRC/BBSRC-funded U.K. Doctoral Training Centre in synthetic biology, we have developed a new undergraduate module in the subject, and we have established five WISB Research Career Development Fellowships to support young group leaders. Research in Ethical, Legal and Societal Aspects (ELSA) of synthetic biology is embedded in our centre activities. WISB has been highly proactive in building an international research and training network that includes partners in Barcelona, Boston, Copenhagen, Madrid, Marburg, São Paulo, Tartu and Valencia.

  15. XAFS studies of Au nanocrystals passivated by different surfactants

    International Nuclear Information System (INIS)

    The electronic and atomic structures of Au nanocrystals affected by different surfactants (PPh3, PVP, and dodecanethiol) capping were studied by X-ray absorption fine structure (XAFS) at Au L3-edge. For PPh3, PVP, and dodecanethiol-capped Au nanocrystals, the surface Au atoms interact with P, O, and S atoms respectively; however, only for dodecanethiol-capped Au nanocrystals, a significant electron transfer between Au and S atoms is observed. The extend-XAFS results reveal that the atomic structure disorder of Au-Au shell gradually increases from 0.0095 to 0.0152 Å2 when the surfactants goes from PPh3 to dodecanethiol. These results suggest that the surfactants would change the electronic and atomic structures of Au nanocrystals rather than merely passivates on the surface of Au nanocrystals.

    Medieval Icelandic literature recounts stories of both pagans and Christians settling in Iceland. Most of these stories focus on a male protagonist. However one of these tales centres around a female settler, namely Auðr/Unnr djúp(a)úðga Ketilsdóttir. Her story is unique in two senses: firstly, she is one of the few female protagonists among the many male ones in these accounts; secondly, the question of Auðr’s religion is an interesting one and a puzzle at that as two religious traditions ex...

    Two new polar intermetallic compounds Y3Au7Sn3 (I) and Gd3Au7Sn3 (II) have been synthesized and their structures have been determined by single crystal X-ray diffraction (P63/m; Z = 2, a = 8.148(1)/8.185(3), and c = 9.394(2)/9.415(3) for I/II, respectively). They can formally be assigned to the Cu10Sn3 type and consist of parallel slabs of Sn centered, edge-sharing trigonal Au6 antiprisms connected through R3 (R = Y, Gd) triangles. Additional Au atoms reside in the centres of trigonal Au6 prisms forming Au@Au6 clusters with Au–Au distances of 2.906–2.960 Å, while the R–R contacts in the R3 groups are considerably larger than the sums of their metallic radii. These exclusive structural arrangements provide alluring systems to study the synergism between strongly correlated systems, particularly, those in the structure of (II), and extensive polar intermetallic contacts, which has been inspected by measurements of the magnetic properties, heat capacities and electrical conductivities of both compounds. Gd3Au7Sn3 shows an antiferromagnetic ordering at 13 K, while Y3Au7Sn3 is a Pauli paramagnet and a downward curvature in its electrical resistivity at about 1.9 K points to a superconducting transition. DFT-based band structure calculations on R3Au7Sn3 (R = Y, Gd) account for the results of the conductivity measurements and different spin ordering models of (II) provide conclusive hints about its magnetic structure. As a result, chemical bonding analyses of both compounds indicate that the vast majority of bonding originates from the heteroatomic Au–Gd and Au–Sn interactions, while homoatomic Au–Au bonding is evident within the Au@Au6 clusters.

  18. Suppression of ϒ production in d+Au and Au+Au collisions at √(sNN)=200 GeV

    International Nuclear Information System (INIS)

    We report measurements of ϒ meson production in p+p, d+Au, and Au+Au collisions using the STAR detector at RHIC. We compare the ϒ yield to the measured cross section in p+p collisions in order to quantify any modifications of the yield in cold nuclear matter using d+Au data and in hot nuclear matter using Au+Au data separated into three centrality classes. Our p+p measurement is based on three times the statistics of our previous result. We obtain a nuclear modification factor for ϒ(1S+2S+3S) in the rapidity range |y|<1 in d+Au collisions of RdAu=0.79±0.24(stat.)±0.03(syst.)±0.10(p+p syst.). A comparison with models including shadowing and initial state parton energy loss indicates the presence of additional cold-nuclear matter suppression. Similarly, in the top 10% most-central Au+Au collisions, we measure a nuclear modification factor of RAA=0.49±0.1(stat.)±0.02(syst.)±0.06(p+psyst.), which is a larger suppression factor than that seen in cold nuclear matter. Our results are consistent with complete suppression of excited-state ϒ mesons in Au+Au collisions. The additional suppression in Au+Au is consistent with the level expected in model calculations that include the presence of a hot, deconfined Quark–Gluon Plasma. However, understanding the suppression seen in d+Au is still needed before any definitive statements about the nature of the suppression in Au+Au can be made

  20. Using supported Au nanoparticles as starting material for preparing uniform Au/Pd bimetallic catalysts

    One of the best methods for producing bulk homogeneous (composition) supported bimetallic AuPd clusters involves the immobilization of a protected Au seed followed by the addition of Pd. This paper investigates the importance of this gold seed in controlling the resulting bimetallic AuPd clusters structures, sizes and catalytic activities by investigating three different gold seeds. Uniform Au-Pd alloy were obtained when a steric/electrostatic protecting group, poly(vinyl alcohol) (PVA), was used to form the gold clusters on activated carbon (AC). In contrast Au/AC precursors prepared using Au nanoparticles with only electrostatic stabilization (tetrakis(hydroxypropyl)phosphonium chloride (THPC)), or no stabilization (magnetron sputtering) produced inhomogeneous alloys and segregation of the gold and palladium. The uniform alloyed catalyst (Pd{at}Au{sub PVA}/AC) is the most active and selective catalyst, while the inhomogenous catalysts are less active and selective. Further study of the PVA protected Au clusters revealed that the amount of PVA used is also critical for the preparation of uniform alloyed catalyst, their stability, and their catalytic activity.

    Full Text Available The adsorption of the proteins CD13, mucin and bovine serum albumin on VLGXE-Au and YNGRT-Au interfaces was monitored by electrochemical impedance spectroscopy in the presence of [Fe(CN6]3−/4−. The hydrophobicity of the Au surface was tailored using specific peptides, blocking agents and diluents. The combination of blocking agents (ethanolamine or n-butylamine and diluents (hexanethiol or 2-mercaptoethanol was used to prepare various peptide-modified Au surfaces. Protein adsorption onto the peptide-Au surfaces modified with the combination of n-butylamine and hexanethiol produced a dramatic decrease in the charge transfer resistance, Rct, for all three proteins. In contrast, polar peptide-surfaces induced a minimal change in Rct for all three proteins. Furthermore, an increase in Rct was observed with CD13 (an aminopeptidase overexpressed in certain cancers in comparison to the other proteins when the VLGXE-Au surface was modified with n-butylamine as a blocking agent. The electrochemical data indicated that protein adsorption may be modulated by tailoring the peptide sequence on Au surfaces and that blocking agents and diluents play a key role in promoting or preventing protein adsorption. The peptide-Au platform may also be used for targeting cancer biomarkers with designer peptides.

    "There are only two ways to life your live. One is as though nothing is a miracle. The other is as though everything is a miracle." Albert Einstein Children's Centre "3 in 1" is an extracurricular unit linked to the High School of Zlatartitsa, St. Cyril and St. Methodius, accomplished with the help of the municipality and many volunteers from the local community. With its activity it forms in children patriotic spirit, love for nature, active citizenship, and an impulse for a healthy life through communication with nature, saving the traditions and history, insurance of equality of the kids of the local five ethnicities and participation in activities in the sphere of science, art, sport and tourism. The educational work is mainly directed towards kids with difficulties with communication, hyperactivity, aggression, problems in their families, or those deprived of parental care. For a few years in the Children's Centre there have been clubs of interests: "Gardeners" - kids cultivate a garden. They plow, dig, plant, put in, irrigate and weed under the watch of Ms Stafka Nikolova, parents, and volunteers of the local community. The ecologically clean products - vegetables and fruits, kids use to cook delicious meals, sell, or give away. Weeds are also utilized; they are making herbarium out of them. "Cooks" - "What to have for lunch, when mom is out?". One can learn a lot of wonderful recipes from the club "Cooks". Products are own made, raised with love. In 2010, on the on the annual traditional holiday of the garden soup in Zlataritsa, the little cooks won third prize for making a delicious vegetable soup. On the same day, the 26 years old Nadezhda Savova, Cultural and Social Anthropology PhD in Princeton, founded the second community bakery in Bulgaria in Children's Centre "3 in1". Nadezhda Savova was declared traveler of 2012 by National Geographic. After the baking house in Gabrovo and Zlataritsa, Nadezhda also founded such projects in Sofia, Varna and Ruse

    International Nuclear Information System (INIS)

    Morocco has a long and rich history in nuclear technology which began in the 1950s with the development of nuclear techniques in several important socio-economic fields such as medicine, agriculture and industrial applications. The development of nuclear technology evolved over various organizations, primarily within the Ministry of Education. However, with the formation of the National Centre for Nuclear Energy and Technology (CNESTEN) the development of nuclear technology in Morocco has been reinforced. Morocco is looking forward and actively pursuing alternative sources of energy and has a very strong interest in nuclear power generation and associated technologies such as nuclear desalination. Entry into these new technologies is required since there are no natural sources of energy, Morocco currently imports most of its energy needs from abroad and has a rapidly expanding energy need. In this paper, we present CNESTEN and its main facilities, missions, research programmes, human resources, training, education, national and international cooperation, etc

The identified concepts and sub-concepts were classified and developed into in a conceptual model within the six elements of the practice theory, as outlined by Dickoff, James and Wiedenbach’s (1968:423 survey list cited by Madela-Mntla (1999:69 in Tlakula (1999:119. These elements are recipient, agent, context, procedure, purpose and dynamic. The relational statements derived after conceptualisation of each of the six concepts were inferred through the process of deductive analysis and synthesis. The development of the woman-centred childbirth model contained six components, namely, goals, concepts, definitions, relationships, structures and assumptions, as outlined in Chinn and Jacobs (1987:116. The model was evaluated in accordance with Chinn and Kramer’s (1995:134–135 method and refined by experts in midwifery practice and model generation. Limitations were recognised and recommendations made.

Despite negatively-charged nitrogen-vacancy (NV$^-$) centres being discussed as a potential laser medium since the 1980's, there have been no definitive observations of stimulated emission from ensembles of NV$^-$ to date. Reasons for this lack of demonstration include the short excited state lifetime and the occurrence of photo-ionisation to the neutral charge state by light around the zero-phonon line. Here we show both theoretical and experimental evidence for stimulated emission from NV$^-$ states using light in the phonon-sidebands. Our system uses a continuous wave pump laser at 532 nm and a pulsed stimulating laser that is swept across the phononic sidebands of the NV$^-$. Optimal stimulated emission is demonstrated in the vicinity of the three-phonon line at 700 nm. Furthermore, we show the transition from stimulated emission to photoionisation as the stimulating laser wavelength is reduced fro...

  17. Training courses at the TRICO Nuclear Centre

    International Nuclear Information System (INIS)

    Aware of the importance that nuclear techniques are assuming in everyday life and also their importance for the world of tomorrow, the TRICO Nuclear Centre has organized regular training courses at different educational levels. For example in 1960 a university course was given in biology and medicine; in 1963 a course for technicians in nuclear techniques; in 1964 a second university course on the subject of activation analysis and labelled molecules; in 1965 a course on the application of radioisotopes in agronomy and biology, and in 1966 two courses were given - one on recycling, intended for secondary-school pupils, and the other for university research-workers. An analysis of these courses is given in the paper. (author)

  2. Personal dosimetry in the PET Centre Prague

    International Nuclear Information System (INIS)

    This work is focused on radiation protection in the PET Centre Prague. The personal year dose equivalents of physicians, technologists and labtechnologists in the period 1997-2000 are presented. Dose equivalents are listed for each group as collective, mean and maximum dose equivalents and number of people in the evaluated group. There is an increase in the dose equivalents in 1999 when the PET scanner was installed. Later on, when personnel was trained and better local shielding was used, the increase is not much higher even though the number of patients investigated per day doubled. The radiation field measurements showed that the radiation dose equivalent rate outside the controlled area is on the background level of about 0.17-0.18 mSv/hour. (author)

  4. Twin Jets from the Centres of Galaxies

    Conceivably, the centres of all massive galaxies emit continuous antipodal beams of relativistic particles. We shall argue that these beams consist of highly relativistic electrons and positrons. At formation, the beams plough a channel through the ambient medium; the swept-up matter repeatedly stalls the particles which thereby follow closely the ambient pressure gradient. Thereafter, when the relativistic beam particles traverse these swarms of swept-up filamentary matter, they are repeatedly forced to bypass individual filaments and radiate (in the direction of their instantaneous motion). This forward-peaked radiation pattern can explain the preferred one-sided-ness of the observed radio/optical/X-ray knots in the jets. Pressure confinement focusses the beams, and temporarily freezes the channels. Interaction with the intergalactic wind can bend the beams into the shape of a warpedU, on length scales above some 20 kpc. The observed morphologies of extragalactic radio sources find a common explanation.

    Loin steaks and cubes of M. semimembranosus from eight (12 month old) Galloway steers and eight (16-18 month old) Charolais cross steers raised in England and from which the meat was conditioned for 2 or 10 days, were assessed in research centres in Belgium, Denmark, England, France, the Federal Republic of Germany, Ireland, Italy and the Netherlands. Laboratory panels assessed meat by grilling the steaks and cooking the cubes in casseroles according to local custom using scales developed locally and by scales used frequently at other research centres. The meat was mostly of good quality but with sufficient variation to obtain meaningful comparisons. Tenderness and juiciness were assessed most, and flavour least, consistently. Over the 32 meats, acceptability of steaks and casseroles was in general compounded from tenderness, juiciness and flavour. However, when the meat was tough, it dominated the overall judgement; but when tender, flavour played an important rôle. Irish and English panels tended to weight more on flavour and Italian panels on tenderness and juiciness. Juciness and tenderness were well correlated among all panels except in Italy and Germany. With flavour, however, Belgian, Irish, German and Dutch panels ranked the meats similarly and formed a group distinct from the others which did not. The panels showed a similar grouping for judgements of acceptability. French and Belgian panels judged the steaks from the older Charolais cross steers to have more flavour and be more juicy than average and tended to prefer them. Casseroles from younger steers were invariably preferred although the French and Belgian panels judged aged meat from older animals equally acceptable. These regional biases were thought to be derived mainly from differences in cooking, but variations in experience and perception of assessors also contributed. PMID:22055992

    This paper studies the coalescence of heteroclusters Au767 and Ag767 by using molecular dynamics with the embedded atom method,where layer atomic energy is employed to describe the potential energy variation of per atom in different layers along radial direction.The results show that the coalescence is driven by releasing the atomic energy of the coalesced zone.The deformation,which is induced by substitutional and vacancy diffusion during the coalescence,makes the coalesced cluster disorder.If the summation of the thermal energy and the released atomic energy is large enough to keep the disorder state,the clusters form a metastable liquid droplet;otherwise,the clusters coalesce into a solid cluster when the coalesced cluster reaches the equilibrium state,and the coalesced cluster experiences liquid to solid ordering changes during the coalescence of a solid Au767 with a liquid Ag767 and a liquid Au767 with a liquid Ag767.The centre of figure of the cluster system is shifted during the coalescence process,and higher coalescence temperature causes larger shift degree.

  7. Low temperature paramagnetic scattering from YbInAu2 and YbAl3

    International Nuclear Information System (INIS)

    We have investigated paramagnetic scattering from YbInAu2 and compare it with that from YbAl3 which has closely comparable low temperature bulk susceptibility χ(0) as well as linear specific heat coefficient γ. Whereas YbAl3 shows a 'gap-like' spectral response at low temperatures (5K) with an energy gap of similar 32meV, the low temperature magnetic response of YbInAu2 shows the more common inelastic Lorentzian form centred on similar 38meV (width similar 25meV), which can also be closely represented by the Kuramoto-Mueller Hartmann spectral function yielding a Kondo energy of similar 35meV. The integrated spectral intensity (calibrated relative to the bulk susceptibility) suggests a partial 4f occupancy of similar 0.7 (±0.05), closely similar to that found for YbAl3. The presence of optic phonons at energies close to the characteristic Kondo energy in YbAl3 and their apparent absence at similar energies in YbInAu2 points to coupling with phonons as a possible mechanism for the marked 'distortion' of the spectral shape to its 'gap-like' form in YbAl3.

  8. Factors determining the structure of Au, Ag and Cr thin layers deposited on alkaline halogen substrates

    International Nuclear Information System (INIS)

    Metal thin layer deposited on dielectric substrates, in general, and on alkaline halogen substrates, in particular, have been thoroughly studied in order to make clear the phenomenology of the formation and development processes, to set out fundamental factors in determining their structure and to determine optimum conditions for the obtaining of monocrystal thin layers or metastable structured thin layers in view of their practical applications. Starting from a systematic programme of experimental investigations, an attempt has been made to investigate the influence of substrate composition, of defects within alkaline halogen substrates and of deposition conditions on the orientated formation and development of Au layer and on the formation of metastable Cr-delta structures in the case of thin Cr layers. A systematic study on the influence of deposition conditions and on alkaline halogen substrates with colloidal centres is carried out in view of elaborating a method for the development of monocrystal Au layers for ''channeling targets''. A correlation between characteristic parameters which define the atomic theory of nucleation including deposition conditions and material parameters, Au parameters for the case of epitaxial layers deposited on KBr, KCl and NaCl substrates has been attempted.

  9. Jets and dijets in Au+Au and p+p collisions at RHIC

    Energy Technology Data Exchange (ETDEWEB)

    Hardtke, D.; STAR Collaboration

    2002-12-09

    Recent data from RHIC suggest novel nuclear effects in the production of high p{sub T} hadrons. We present results from the STAR detector on high p{sub T} angular correlations in Au+Au and p+p collisions at {radical}S = 200 GeV/c. These two-particle angular correlation measurements verify the presence of a partonic hard scattering and fragmentation component at high p{sub T} in both central and peripheral Au+Au collisions. When triggering on a leading hadron with p{sub T}>4 GeV, we observe a quantitative agreement between the jet cone properties in p+p and all centralities of Au+Au collisions. This quantitative agreement indicates that nearly all hadrons with p{sub T}>4 GeV/c come from jet fragmentation and that jet fragmentation properties are not substantially modified in Au+Au collisions. STAR has also measured the strength of back-to-back high p{sub T} charged hadron correlations, and observes a small suppression of the back-to-back correlation strength in peripheral collisions, and a nearly complete disappearance o f back-to-back correlations in central Au+Au events. These phenomena, together with the observed strong suppression of inclusive yields and large value of elliptic flow at high p{sub T}, are consistent with a model where high p{sub T} hadrons come from partons created near the surface of the collision region, and where partons that originate or propagate towards the center of the collision region are substantially slowed or completely absorbed.

    The transverse momentum (p_T) spectra and ratios of identified charged hadrons (\\pi^+/-, K^+/-, p, p^bar) produced in sqrt(s_NN)=200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to p_T=6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to p_T=4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate p_T region, between 2--5 GeV/c, a significant enhancement of baryon to meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions, and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class of central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The p_T dependent particle ratios for these classes display a remarkable similarity, which is then discussed.

    2016-05-01

    Different mechanisms of radiation damage of wide-gap metal oxides as well as a dual influence of impurity ions on the efficiency of radiation damage have been considered on the example of binary ionic MgO and complex ionic-covalent Lu3Al5O12 single crystals. Particular emphasis has been placed on irradiation with ∼2 GeV heavy ions (197Au, 209Bi, 238U, fluence of 1012 ions/cm2) providing extremely high density of electronic excitations within ion tracks. Besides knock-out mechanism for Frenkel pair formation, the additional mechanism through the collapse of mobile discrete breathers at certain lattice places (e.g., complex impurity centres) leads to the creation of complex defects that involve a large number of host atoms. The experimental manifestations of the radiation creation of intrinsic and impurity antisite defects (Lu|Al or Ce|Al - a heavy ion in a wrong cation site) have been detected in LuAG and LuAG:Ce3+ single crystals. Light doping of LuAG causes a small enhancement of radiation resistance, while pair impurity centres (for instance, Ce|Lu-Ce|Al or Cr3+-Cr3+ in MgO) are formed with a rise of impurity concentration. These complex impurity centres as well as radiation-induced intrinsic antisite defects (Lu|Al strongly interacting with Lu in a regular site) tentatively serve as the places for breathers collapse, thus decreasing the material resistance against dense irradiation.

    Successful operation of the LHC and its experiments is crucial to the future of the worldwide high-energy physics program. Remote operations and monitoring centres have been established for the CMS experiment in several locations around the world. The development of remote centres began with the LHC{at}FNAL ROC and has evolved into a unified approach with distributed centres that are collectively referred to as 'CMS Centres Worldwide'. An overview of the development of remote centres for CMS will be presented, along with a synopsis of collaborative tools that are used in these centres today and trends in the development of remote operations capabilities for high-energy physics.

    The present work proposes a theoretical method called ionization dynamics to derive the ionic charge state distribution. Using relativistic quantum mechanics to calculate the energy level lifetime and average ionic lifetime of each ion, the first-order ionization rate constant can be obtained. Based on these data, from the solution of differential equations for consecutive-irreversible ionization reactions, one will be able to derive the ionic charge state distribution.The calculated average positive charge 49.24 of Au48+ ~ Au52+ and their relative distribution are in good agreement with the results of Lawrence Livermore National Laboratory.

    Polymerase chain reaction (PCR) is a useful technique for in vitro amplification of a DNA fragment. In this paper, a PCR procedure using Au nanoparticle (AuNP) -bound primers was systemically studied. The 5′-SH- (CH2)6-modified primers were covalently attached to the AuNP surface via Au-S bonds, and plasmid pBluescript SK was used as a template. The effects of the concentration of AuNP-bound primers, annealing temperature and PCR cycles were evaluated, respectively. The results indicate that PCR can proceed successfully under optimized condition, with either forward or reverse primers bound to the AuNP surface or with both the two primers bound to the AuNP surface. Development of PCR procedure based on AuNPs not only makes the isolation of PCR products very convenient, but also provides novel methods to prepare AuNP-bound ssDNA and nanostructured material.

  16. Synthesis and characterization in AuCu–Si nanostructures

    International Nuclear Information System (INIS)

    Au/Cu bilayers with different Au:Cu concentrations (25:75, 50:50 and 75:25 at.%) were deposited on Si(100) substrates by thermal evaporation. The thicknesses of all Au/Cu bilayers were 150 nm. The alloys were prepared by thermal diffusion into a vacuum oven with argon atmosphere at 690 K during 1 h. X-ray diffraction analysis revealed different phases of AuCu and CuSi alloys in the samples after annealing process. CuSi alloys were mainly obtained for 25:75 at.% samples, meanwhile the AuCuII phase dominates for samples prepared with 50:50 at.%. Additionally, the Au:Cu alloys with 75:25 at.%, produce Au2Cu3 and Au3Cu phases. The formed alloys were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS) to study the morphology and the elemental concentration of the formed alloys. - Highlights: • AuCu/Si alloy thin films were prepared by thermal diffusion. • Alloys prepared with 50 at.% of Au produce the AuCuII phase. • Alloys prepared with 75 at.% of Au produce Au3Cu and Au2Cu3 phases. • All alloys present diffusion of Si and Cu through the CuSi alloy formation

    Au/Cu bilayers with different Au:Cu concentrations (25:75, 50:50 and 75:25 at.%) were deposited on Si(100) substrates by thermal evaporation. The thicknesses of all Au/Cu bilayers were 150 nm. The alloys were prepared by thermal diffusion into a vacuum oven with argon atmosphere at 690 K during 1 h. X-ray diffraction analysis revealed different phases of AuCu and CuSi alloys in the samples after annealing process. CuSi alloys were mainly obtained for 25:75 at.% samples, meanwhile the AuCuII phase dominates for samples prepared with 50:50 at.%. Additionally, the Au:Cu alloys with 75:25 at.%, produce Au{sub 2}Cu{sub 3} and Au{sub 3}Cu phases. The formed alloys were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS) to study the morphology and the elemental concentration of the formed alloys. - Highlights: • AuCu/Si alloy thin films were prepared by thermal diffusion. • Alloys prepared with 50 at.% of Au produce the AuCuII phase. • Alloys prepared with 75 at.% of Au produce Au{sub 3}Cu and Au{sub 2}Cu{sub 3} phases. • All alloys present diffusion of Si and Cu through the CuSi alloy formation.

  18. XPS and DFT studies of the electronic structures of AgAuS and Ag3AuS2

    International Nuclear Information System (INIS)

    Highlights: • Photoelectron spectra and DOS were obtained for AgAuS and Ag3AuS2 for the first time. • Essentially higher Au 4f binding energy was found in case of Ag3AuS2. • DFT calculations show a larger overlapping of S 3p and Au 5d valence states for Ag3AuS2. • Energy position of Au 4f levels is mainly influenced by Au–Ag interactions. - Abstract: X-ray photoelectron spectra of core levels and the valence bands were acquired, and the density-of-states (DOS) were calculated using periodic density functional theory (DFT) for synthetic ternary compounds AgAuS and Ag3AuS2, known as minerals petrovskaite uytenbogaardtite, respectively, for the first time. The chemical shift of the Au 4f binding energy as large as 0.65 eV relative to bulk elemental gold was found for Ag3AuS2, in contrast to only about 0.3 eV for AgAuS. The DFT analysis showed, in particular, that the S 3p states are largely pushed out from the Ag 4d and Au 5d bands affording two sub-bands in the valence region of both substances, but the overlapping of the S 3p and Au 5d states is larger for Ag3AuS2. It was demonstrated that the energy position of Au 4f levels is mainly influenced by Au–Ag interaction, and increasing the number of Ag atoms in the first coordination shell of S–Au–S units on going from AgAuS to Ag3AuS2 results in the positive shift of the Au 4f bands consistent with the experimental data

    Institutions specifically dedicated to treatment of abdominal wall hernias have gained popularity over the last years. This study aimed to determine the current situation of hernia centres worldwide. A web-based search was conducted using the common search engines Google and PubMed. The details recorded were as follows: name of the centre, country, establishment year, administrative structure (hospital affiliated, private practice group, or independent solo practice), whether or not the centre has its own operation room, the number of employed surgeons, preferred anaesthesia type, preferred repair type, laparoscopic technique option, case volume per year, and the number of scientific publications. A total of 182 centres were found in 30 different countries. Eighty-one (44.5 %) centres provide services as part of an affiliation within a general hospital (18 in university hospitals). Only 28 (15.5 %) of the centres have published a paper on abdominal wall hernias indexed by PubMed. The total number of papers in PubMed by 182 centres is 354. We observed that clinical outcomes in hernia centres are not shared globally by publishing them in scientific journals, and whether specific hernia surgeons and centres provide better outcomes in treating abdominal wall hernias, compared to general surgeons who deal with all kinds of surgical procedures, remains unclear.

    The authors report the assessment of the local and locoregional control and of the acute and late toxicity of adjuvant hypo-fractionated radiotherapy in breast cancer treatment. During 1998, 80 women have been treated by conservative or radical surgery and hypo-fractionated tele-cobalto-therapy (36 Gy in five fractions of 3 Gy a week, and a boost of 15 Gy in five fractions in case of conservative surgery). Results are discussed in terms of local and locoregional recurrence, tolerance, late toxicity, global survival, and tumour classification. The irradiation scheme seems perfectly achievable but a greater number of patients and a longer follow-up are required to better assess the efficiency and aesthetic results. Short communication

    2009-06-24

    Photoemission and first-principles DF calculations were used to study the interaction of thiophene with TiC(001) and Au/TiC(001) surfaces. The adsorption strength of thiophene on TiC(001) is weak, and the molecule desorbs at temperatures below 200 K. The molecule binds to Ti centers of TiC(001) through its sulfur atom with negligible structural perturbations. In spite of the very poor desulfurization performance of TiC(001) or Au(111), a Au/TiC(001) system displays a hydrodesulfurization activity higher than that of conventional Ni/MoS(x) catalysts. The AuTiC(001) interactions induce a polarization of electron density around Au which substantially increases the chemical reactivity of this metal. Au nanoparticles drastically increase the hydrodesulfurization activity of TiC(001) by enhancing the bonding energy of thiophene and by helping in the dissociation of H(2) to produce the hydrogen necessary for the hydrogenolysis of C-S bonds and the removal of sulfur. H(2) spontaneously dissociates on small two-dimensional clusters of gold in contact with TiC(001). On these systems, the adsorption energy of thiophene is 0.45-0.65 eV larger than that on TiC(001) or Au(111). Thiophene binds in a eta(5) configuration with a large elongation (approximately 0.2 A) of the C-S bonds. PMID:19530731

  6. Ω production in p+p, Au+Au and U+U collisions at STAR

    International Nuclear Information System (INIS)

    We report STAR's high precision measurements on Ω production at mid-rapidity from √(s)=200 GeVp+p, central √(sNN)=200 GeVAu+Au, and central √(sNN)=193 GeVU+U collisions. With the significantly reduced uncertainty in p+p reference, we observe that the Ω enhancement factors at RHIC are in between SPS and LHC, while enhancement factors are systematically larger in central U+U collisions than in central Au+Au collisions. The ΩRAA is much larger than protons and pions for pT up to 4 GeV/c in central Au+Au collisions. The ratio of ΩRAA in central U+U to that in central Au+Au collisions is above unity for pT up to 6 GeV/c, which indicates coalescence/recombination to be the dominant production mechanism for Ω in these collisions for the measured pT range

  7. Plasmonic Fano resonance and dip of Au-SiO2-Au nanomatryoshka.

    2013-01-01

    This study theoretically investigates Fano resonances and dips of an Au-SiO2-Au nanomatryoshka that is excited by a nearby electric dipole. An analytical solution of dyadic Green's functions is used to analyze the radiative and nonradiative power spectra of a radial dipole in the proximity of a nanomatryoshka. From these spectra, the plasmon modes and Fano resonances that accompany the Fano dips are identified. In addition, the scattering and absorption spectra of a nanomatryoshka that is illuminated by a plane wave are investigated to confirm these modes and Fano dips. Our results reveal that a Fano dip splits each of the dipole and quadrupole modes into bonding and anti-bonding modes. The Fano dip and resonance result from the destructive interference of the plasmon modes of the Au shell and the Au core. The Fano factors that are obtained from the nonradiative power spectra of the Au shell and the Au core of a nanomatryoshka are in accordance with those obtained from the absorption cross section spectra. Moreover, these Fano factors increase as the plasmonic coupling of the Au shell with the core increases for both dipole and quadrupole modes. PMID:24206789

  8. A SDMS Model: Early Warning Coordination Centres

    2010-05-01

    Following the tsunami disaster in 2004, the General Secretary of the United Nations (UN) Kofi Annan called for a global early warning system for all hazards and for all communities. He also requested the ISDR (International Strategy fort Disaster Reduction) and its UN partners to conduct a global survey of capacities, gaps and opportunities in relation to early warning systems. The produced report, "Global survey of Early Warning Systems", concluded that there are many gaps and shortcomings and that much progress has been made on early warning systems and great capabilities are available around the world. However, it may be argued that an early warning system (EWS) may not be enough to prevent fatalities due to a natural hazard; i.e., it should be seen as part of a ‘wider' or total system. Furthermore, an EWS may work very well when assessed individually but it is not clear whether it will contribute to accomplish the purpose of the ‘total disaster management system'; i.e., to prevent fatalities. For instance, a regional EWS may only work if it is well co-ordinated with the local warning and emergency response systems that ensure that the warning is received, communicated and acted upon by the potentially affected communities. It may be argued that without these local measures being in place, a regional EWS will have little impact in saving lives. Researchers argued that unless people are warned in remote areas, the technology is useless; for instance McGuire [5] argues that: "I have no doubt that the technical element of the warning system will work very well,"…"But there has to be an effective and efficient communications cascade from the warning centre to the fisherman on the beach and his family and the bar owners." Similarly, McFadden [6] states that: "There's no point in spending all the money on a fancy monitoring and a fancy analysis system unless we can make sure the infrastructure for the broadcast system is there,"… "That's going to require a lot

  9. Molecular beam epitaxy of GaAs nanowires and their sustainability for optoelectronic applications. Comparing Au- and self-assisted growth methods

    Energy Technology Data Exchange (ETDEWEB)

    Breuer, Steffen

    2011-09-28

    In this work the synthesis of GaAs nanowires by molecular beam epitaxy (MBE) using the vapour-liquid-solid (VLS) mechanism is investigated. A comparison between Au- and self-assisted VLS growth is at the centre of this thesis. While the Au-assisted method is established as a versatile tool for nanowire growth, the recently developed self-assisted variation results from the exchange of Au by Ga droplets and thus eliminates any possibility of Au incorporation. By both methods, we achieve nanowires with epitaxial alignment to the Si(111) substrates. Caused by differences during nanowire nucleation, a parasitic planar layer grows between the nanowires by the Au-assisted method, but can be avoided by the self-assisted method. Au-assisted nanowires grow predominantly in the metastable wurtzite crystal structure, while their self-assisted counterparts have the zincblende structure. All GaAs nanowires are fully relaxed and the strain arising from the lattice mismatch between GaAs and Si of 4.1 % is accommodated by misfit dislocations at the interface. Self-assisted GaAs nanowires are generally found to have vertical and non-polar side facets, while tilted and polar nanofacets were described for Au-assisted GaAs nanowires. We employ VLS nucleation theory to understand the effect of the droplet material on the lateral facets. Optoelectronic applications require long minority carrier lifetimes at room temperature. We fabricate GaAs/(Al,Ga)As core-shell nanowires and analyse them by transient photoluminescence (PL) spectroscopy. The results are 2.5 ns for the self-assisted nanowires as well as 9 ps for the Au-assisted nanowires. By temperature-dependent PL measurements we find a characteristic activation energy of 77 meV that is present only in the Au-assisted nanowires. We conclude that most likely Au is incorporated from the droplets into the GaAs nanowires and acts as a deep, non-radiative recombination centre.

  10. Establishing a National Nuclear Security Support Centre

    International Nuclear Information System (INIS)

    The responsibility for creating and sustaining a nuclear security regime for the protection of nuclear and other radiological material clearly belongs to the State. The nuclear security regime resembles the layers of an onion, with the equipment and personnel securing the borders and ports representing the outer layer, and nuclear power, research reactors and nuclear medicine facilities representing the inner layers, and the actual target material representing the core. Components of any nuclear security regime include not only technological systems, but the human resources needed to manage, operate, administer and maintain equipment, including hardware and software. This publication provides practical guidance on the establishment and maintenance of a national nuclear security support centre (NSSC) as a means to ensure nuclear security sustainability in a State. An NSSC's basic purpose is to provide a national focal point for passing ownership of nuclear security knowledge and associated technical skills to the competent authorities involved in nuclear security. It describes processes and methodologies that can be used by a State to analyse the essential elements of information in a manner that allows several aspects of long term, systemic sustainability of nuclear security to be addressed. Processes such as the systematic approach to training, sometimes referred to as instructional system design, are the cornerstone of the NSSC concept. Proper analysis can provide States with data on the number of personnel requiring training and instructors needed, scale and scope of training, technical and scientific support venues, and details on the type and number of training aids or simulators required so that operational systems are not compromised in any way. Specific regulatory guidance, equipment or technology lists, or specifications/design of protection systems are not included in this publication. For such details, the following IAEA publications should be consulted

  11. Hokkaido University Nuclear Reaction Data Centre (JCPRG)

    International Nuclear Information System (INIS)

    A research project to compile Charged-Particle Nuclear Reaction Data was initiated in 1974, which was approved by the Theoretical Nuclear Physics Society and the Experimental Nuclear Physics Society in Japan. When this project started, a mutual agreement with the JAERI Nuclear Data Centre was concluded; this Study Group would be responsible for Charged- Particle Nuclear Reaction Data while JAERI would be in charge of Nuclear Neutron Data. The original database (NRDF, Nuclear Reaction Data File) was devised by the Study Group under the sponsorship of the Japanese Ministry of Education, Science and Culture through the Grant-in-Aid for Scientific Research. With data storage and retrieval functions added to the original NRDF system, the project developed from the stage of research and development to the practical working stage of data compilation and data dissemination in 1987. Subsequently, the Study Group was reorganized to become the Japan Charged-Particle Nuclear Reaction Data Group (JCPRG) in NRDC, and was assigned an annual budget through the Nuclear Physics Laboratory, Department of Physics, Hokkaido University by the Ministry of Education, Science and Culture. This regular JCPRG budget ended in 2001, and was replaced by a yearly competitive process. The primary aims of JCPRG are to construct and provide an academic-oriented database according to an original and unique format by compiling and storing all charged-particle nuclear reaction data produced with Japanese accelerators. JCPRG is also responsible for transforming NRDF to EXFOR format, and sending these files to IAEA-NDS. On April 1, 2007, the Japan Charged-Particle Nuclear Reaction Data Group (JCPRG) was reorganized to the Hokkaido University Nuclear Reaction Data Centre (JCPRG) as a measure taken in the Faculty of Science, Hokkaido University. At the same time, the graduate school collaboration field ''Nuclear Data'' science with Japan Atomic Energy Agency (JAEA) was established in the Department of

    Yields, correlation shapes, and mean transverse momenta \\pt{} of charged particles associated with intermediate to high-\\pt{} trigger particles ($2.5 < \\pt < 10$ \\GeVc) in d+Au and Au+Au collisions at $\\snn=200$ GeV are presented. For associated particles at higher $\\pt \\gtrsim 2.5$ \\GeVc, narrow correlation peaks are seen in d+Au and Au+Au, indicating that the main production mechanism is jet fragmentation. At lower associated particle $\\pt < 2$ \\GeVc, a large enhancement of the near- ($\\dphi \\sim 0$) and away-side ($\\dphi \\sim \\pi$) associated yields is found, together with a strong broadening of the away-side azimuthal distributions in Au+Au collisions compared to d+Au measurements, suggesting that other particle production mechanisms play a role. This is further supported by the observed significant softening of the away-side associated particle yield distribution at $\\dphi \\sim \\pi$ in central Au+Au collisions.

    Background: Although prior studies have suggested an inverse association between liver transplant centre volume and postoperative patient mortality, more recent analyses have failed to confirm this association. To date, all studies of the relationship between centre volume and outcomes in liver transplantation have been cross-sectional in design. Objective: The objective of our study was to examine temporal trends in the volume–outcomes relationship for liver transplantation. Methods: We used information obtained from the Scientific Registry of Transplant Recipients (SRTR) programme-specific data reports to examine the outcomes of adult liver transplant recipients stratified by annual centre volume. This relationship between centre volume and patient outcomes was assessed over three consecutive time periods from 2000 through 2007. Results: The overall 25% increase in adult liver transplant volume in the USA from 2000 to 2007 appeared to be distributed fairly equally among existing transplant centres. In the earliest time period of our analysis, high-volume centres achieved superior risk-adjusted 1-year patient outcomes compared with low-volume centres. By the third and most recent time period of the analysis, this discrepancy between the outcomes of high- and low-volume centres was no longer statistically apparent. Conclusions: The relationship between centre volume and patient outcomes for liver transplantation in the USA has become less pronounced over time, suggesting that the use of procedure volume as a marker of liver transplant centre quality cannot be justified. The performance-based review process currently utilized in the USA may have contributed to this diminishing influence of centre volume on liver transplant recipient outcomes. This type of review process should be considered as a potential alternative to the volume-based referral initiatives that have been developed for other non-transplant, complex surgical procedures.

    The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has measured omega meson production via leptonic and hadronic decay channels in p+p, d+Au, Cu+Cu, and Au+Au collisions at sqrt(s_NN) = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu+Cu and Au+Au collisions show that omega production has a suppression pattern at high transverse momentum, similar to that of pi^0 and eta in central collisions, but no suppression is observed in peripheral collisions. The nuclear modification factors, R_AA, are consistent in Cu+Cu and Au+Au collisions at similar numbers of participant nucleons.

  15. Crystal structure of Au9In4(h) and Au7In3

    International Nuclear Information System (INIS)

    The phase Au9In4(h) crystallizes in the Cu9Al4-type structure and Au7In3 has a hexagonal crystal structure with 60 atoms in the elementary cell. The structure is related to the γ-brass structure but with a different distribution of vacancies and another system of displacements. A spatial correlation of the core electrons with a very simple commensurability may be traced in the structure, together with a valence electron correlation which is geometrically related to the core electron correlation by a factor of 2. This energetically favourable binding relationship provides an argument in favour of the stability of Au7In3. (Auth.)

    The chemical inertness typically observed for Au does not imply a general inability to form stable bonds with non-metals but is rather a consequence of high reaction barriers. The Au-S interaction is probably the most intensively studied interaction of Au surfaces with non-metals as, for example, it plays an important role in Au ore formation, and controls the structure and dynamics of thiol-based self-assembled-monolayers (SAMs). In recent years a quite complex picture of the interaction of sulfur with Au(111) surfaces emerged, and a variety of S-induced surface structures was reported under different conditions. The majority of these structures were interpreted in terms of a static Au surface, where the positions of the Au atoms remain essentially unperturbed. Here we demonstrate that the Au(111) surface exhibits a very dynamic character upon interaction with adsorbed sulfur: low sulfur coverages modify the surface stress of the Au surface leading to lateral expansion of the surface layer; large-scale surface restructuring and incorporation of Au atoms into a growing two-dimensional AuS phase were observed with increasing sulfur coverage. These results provide new insight into the Au-S surface chemistry, and reveal the dynamic character of the Au(111) surface.

    High expectations for Norway's Centres for Environment-friendly Energy Research (FME).The FME centres address a broad range of areas, allcentral to developing the energy sector of the future. The activities of the eight centres established in 2009 focus on renewable energy, raising energy efficiency, energy planning, and carbon capture and storage (CCS). In 2011 three new FME centres were established which focus on social science-related energy research. The FME scheme is a direct follow-up of the broad-based political agreement on climate policy achieved in the Storting in January 2008, and of the national RandD Energi21 strategy submitted in February 2008 to the Ministry of Petroleum and Energy. In April 2008 the Research Council of Norway's Executive Board decided to launch a process to establish centres for environment-friendly energy research, and a funding announcement was issued that same year. In 2010 it was decided that additional FME centres would be established in the field of social science-related energy research. After a thorough assessment of each project (based on feasibility, scientific merit, potential to generate value creation and innovation, and composition of the consortium) eight applicants were selected to become FME centres in February 2009. A new call for proposals was issued in 2010, and three more centres were awarded FME status in February 2011. The objective of the FME scheme is to establish time-limited research centres which conduct concentrated, focused and long-term research of high international calibre in order to solve specific challenges in the energy sphere. The selected centres must exhibit higher goals, a longer-term perspective and a more concentrated focus than is required under other funding instruments for the same scientific area. The make-up of the centres is critical to achieving this objective. The centres bring together Norway's leading research institutions and key players in private enterprise, the

    International Nuclear Information System (INIS)

    A Centre for Nuclear and Accelerator Technologies (CENTA) has been established at the Faculty of Mathematics, Physics and Informatics of the Comenius University in Bratislava comprising of a tandem laboratory designed for the Accelerator Mass Spectrometry (AMS) and Ion Beam Analysis (IBA). The 3 MV Pelletron accelerator is a key feature of the equipment which will enable to carry out state of the art research in physical, environmental, material, biological and medical sciences in collaboration with leading European and world laboratories. The laboratory is further equipped with two ion sources - Alphatros (RF source for H and He ions) and MC-SNICS source (target wheel with 40 positions for solid targets), and low and high energy analyzers of ions (all equipment of National Electrostatics Corp., USA). We shall discuss in detail development of methods for analysis of 14C around nuclear power plant in Jaslovske Bohunice, and present results of temporal 14C variations in atmospheric carbon dioxide and in tree rings collected at the monitoring stations in Zlkovce and in Bratislava.

    International Nuclear Information System (INIS)

    Full text: Accelerator Mass Spectrometry (AMS) began at ANTARES in late 1991. Many technical improvements and upgrades to the AMS measurement system have taken place since then. The AMS Centre routinely measures 14C (to better than 1% precision), 36Cl and 129I. The capability to measure 10Be and 26Al, is established although further development is still in progress. A capability to analyse Actinides is being established and is the subject of another paper to this conference. This paper reviews some of the more recent technical improvements to the facility. For our 14C analyses a new gas stripper system and high resolution ExB velocity analyser have been installed and are in routine operation. The gas stripper is also used for most other isotopes. A new 90 degree spherical ESA allows 129I measurements without the need for time-of-flight analysis. Installation of a critical insulation flange in the isotope cycling system has permitted bouncing of 12C- and the measurement of 13C/12C ratios. A complete set of Dowlish tubes now allows spark free operation to 8 MV for our 10Be and 36Cl measurements. The very recent installation of pelletron chains is being assessed
