Abstract

Background High rates of food insecurity are documented among Inuit households in Canada; however, data on food insecurity prevalence and seasonality for Inuit households with children are lacking, especially in city centres. This project: (1) compared food consumption patterns for households with and without children, (2) compared the prevalence of food insecurity for households with and without children, (3) compared food consumption patterns and food insecurity prevalence between seasons, and (4) identified factors associated with food insecurity in households with children in Iqaluit, Nunavut, Canada. Methods Randomly selected households were surveyed in Iqaluit in September 2012 and May 2013. Household food security status was determined using an adapted United States Department of Agriculture Household Food Security Survey Module. Univariable logistic regressions were used to examine unconditional associations between food security status and demographics, socioeconomics, frequency of food consumption, and method of food preparation in households with children by season. Results Households with children (n = 431) and without children (n = 468) participated in the survey. Food insecurity was identified in 32.9% (95% CI: 28.5–37.4%) of households with children; this was significantly higher than in households without children (23.2%, 95% CI: 19.4–27.1%). The prevalence of household food insecurity did not significantly differ by season. Demographic and socioeconomic characteristics of the person responsible for food preparation, including low formal education attainment (ORSept = 4.3, 95% CI: 2.3–8.0; ORMay = 3.2, 95% CI: 1.8–5.8), unemployment (ORSept = 1.1, 95% CI: 1.1–1.3; ORMay = 1.3, 95% CI: 1.1–1.5), and Inuit identity (ORSept = 8.9, 95% CI: 3.4–23.5; ORMay = 21.8, 95% CI: 6.6–72.4), were associated with increased odds of food insecurity in households with children. Fruit and vegetable consumption (ORSept = 0.4, 95% CI: 0.2–0.8; ORMay = 0.5, 95% CI: 0.2–0.9), as well as eating cooked (ORSept = 0.5, 95% CI: 0.3–1.0; ORMay = 0.5, 95% CI: 0.3–0.9) and raw (ORSept = 1.7, 95% CI: 0.9–3.0; ORMay = 1.8, 95% CI: 1.0–3.1) fish were associated with decreased odds of food insecurity among households with children, while eating frozen meat and/or fish (ORSept = 2.6, 95% CI: 1.4–5.0; ORMay = 2.0, 95% CI: 1.1–3.7) was associated with increased odds of food insecurity. Conclusions Food insecurity is high among households with children in Iqaluit. Despite the partial subsistence livelihoods of many Inuit in the city, we found no seasonal differences in food security and food consumption for households with children. Interventions aiming to decrease food insecurity in these households should consider food consumption habits, and the reported demographic and socioeconomic determinants of food insecurity.

Abstract

Purpose: To investigate the optimal use of XR-RV3 GafChromic (R) films to assess patient skin dose in interventional radiology while addressing the means to reduce uncertainties in dose assessment. Methods: XR-Type R GafChromic films have been shown to represent the most efficient and suitable solution to determine patient skin dose in interventional procedures. As film dosimetry can be associated with high uncertainty, this paper presents the EURADOS WG 12 initiative to carry out a comprehensive study of film characteristics with a multisite approach. The considered sources of uncertainties include scanner, film, and fitting-related errors. The work focused on studying film behavior with clinical high-dose-rate pulsed beams (previously unavailable in the literature) together with reference standard laboratory beams. Results: First, the performance analysis of six different scanner models has shown that scan uniformity perpendicular to the lamp motion axis and that long term stability are the main sources of scanner-related uncertainties. These could induce errors of up to 7% on the film readings unless regularly checked and corrected. Typically, scan uniformity correction matrices and reading normalization to the scanner-specific and daily background reading should be done. In addition, the analysis on multiple film batches has shown that XR-RV3 films have generally good uniformity within one batch ( LT 1.5%), require 24 h to stabilize after the irradiation and their response is roughly independent of dose rate ( LT 5%). However, XR-RV3 films showed large variations (up to 15%) with radiation quality both in standard laboratory and in clinical conditions. As such, and prior to conducting patient skin dose measurements, it is mandatory to choose the appropriate calibration beam quality depending on the characteristics of the x-ray systems that will be used clinically. In addition, yellow side film irradiations should be preferentially used since they showed a lower dependence on beam parameters compared to white side film irradiations. Finally, among the six different fit equations tested in this work, typically used third order polynomials and more rational and simplistic equations, of the form dose inversely proportional to pixel value, were both found to provide satisfactory results. Fitting-related uncertainty was clearly identified as a major contributor to the overall film dosimetry uncertainty with up to 40% error on the dose estimate. Conclusions: The overall uncertainty associated with the use of XR-RV3 films to determine skin dose in the interventional environment can realistically be estimated to be around 20% (k = 1). This uncertainty can be reduced to within 5% if carefully monitoring scanner, film, and fitting-related errors or it can easily increase to over 40% if minimal care is not taken. This work demonstrates the importance of appropriate calibration, reading, fitting, and other film-related and scan-related processes, which will help improve the accuracy of skin dose measurements in interventional procedures.

Abstract

International audience; Purpose The use of small photon fields is now an established practice in stereotactic radiosurgery and radiotherapy. However, due to a lack of lateral electron equilibrium and high dose gradients, it is difficult to accurately measure the dosimetric quantities required for the commissioning of such systems. Moreover, there is still no metrological dosimetric reference for this kind of beam today. In this context, the first objective of this work was to determine and to compare small fields output factors (OF) measured with different types of active detectors and passive dosimeters for three types of facilities a CyberKnife® system, a dedicated medical linear accelerator (Novalis) equipped with m3 microMLC and circular cones, and an adaptive medical linear accelerator (Clinac 2100) equipped with an additional m3 microMLC. The second one was to determine the kQclin,Q msrfclin,fmsr correction factors introduced in a recently proposed small field dosimetry formalism for different active detectors. Methods Small field sizes were defined either by microMLC down to 6 × 6 mm2 or by circular cones down to 4 mm in diameter. OF measurements were performed with several commercially available active detectors dedicated to measurements in small fields (high resolution diodes IBA SFD, Sun Nuclear EDGE, PTW 60016, PTW 60017; ionizing chambers PTW 31014 PinPoint chamber, PTW 31018 microLion liquid chamber, and PTW 60003 natural diamond). Two types of passive dosimeters were used LiF microcubes and EBT2 radiochromic films. Results Significant differences between the results obtained by several dosimetric systems were observed, particularly for the smallest field size for which the difference in the measured OF reaches more than 20%. For passive dosimeters, an excellent agreement was observed (better than 2%) between EBT2 and LiF microcubes for all OF measurements. Moreover, it has been shown that these passive dosimeters do not require correction factors and can then be used as reference dosimeters. Correction factors for the active detectors have then been determined from the mean experimental OF measured by the passive dosimeters. Conclusions Four sets of correction factors needed to apply the new small field dosimetry formalism are provided for several active detectors. A protocol for small photon beams OF determination based on passive dosimeters measurements has been recently proposed to French radiotherapy treatment centers. © 2013 American Association of Physicists in Medicine.

Abstract

Background: Human papillomaviruses are the most common sexually transmitted infections, and genital warts, caused by HPV-6 and 11, entail considerable morbidity and cost. The natural history of genital warts in relation to HIV-1 infection has not been described in African women. We examined risk factors for genital warts in a cohort of high-risk women in Burkina Faso, in order to further describe their epidemiology. Methods: A prospective study of 765 high-risk women who were followed at 4-monthly intervals for 27 months in Burkina Faso. Logistic and Cox regression were used to identify factors associated with prevalent, incident and persistent genital warts, including HIV-1 serostatus, CD4+ count, and concurrent sexually transmitted infections. In a subset of 306 women, cervical HPV DNA was tested at enrolment. Results: Genital wart prevalence at baseline was 1.6% (8/492) among HIV-uninfected and 7.0% (19/273) among HIV-1 seropositive women. Forty women (5.2%) experienced at least one incident GW episode. Incidence was 1.1 per 100 person-years among HIV-uninfected women, 7.4 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count >200 cells/mu L and 14.6 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count

Abstract

The sandstone of the Macigno Formation quarried along the Fontanella stream near Montereggio (Lunigiana - NW Italy) has been used in XVI-XVII century for the construction of important architectural elements such as ashlar portals in the fortified palace of the Malaspina and in Montereggio village. It is a fine-to coarse- grained feldspathic-lithic sandstone with scarce carbonatic cement and sporadic clay minerals consisting of illite. When exposed to the ravages of time, these artifacts undergo a physical degradation mainly consisting of a superficial exfoliation due either to direct causes i.e. thermoclastic and cryoclastic process or to physical indirect causes related to the presence of ashlar workmanships which leads to an increase of surface microfissuring and water absorption. Phenomena of disgregation with intergranular decohesion are not observed; electron microscopy analysis reveals only superficial corrosion of the mineral phases that acquire rounded morphology and become covered by neck-shaped, thread-like and rose-cut patinas of exclusively Si-Al composition. These latter, together with hollow micrometric spheres of analogous composition, represent the product of firewood combustion. This produces also carbonaceous matter, but not in such quantity to induce the formation of black crusts; conversely, the products of combustion of coal and mineral oils, are very scarce or almost totally absent. Although we do not observe significant effects of weathering, the increase of sandstone microporosity can be chiefly attributed to biotic-related agents such as lichens and musks. The sandstones of the ancient quarry located along the Fontanella stream have been submitted to physical-mechanical tests in order to compare them with known litotypes and to choice the most appropriate products for consolidation and protection in view of possible preservative restoration. These tests show that the sandstones of Montereggio are characterized by low porosity and low water absorption coefficient, excellent values of compressive strength, both under dry conditions and after cycles of freezing, and excellent resistence to flexural strength under concentrated load. All these characteristics make these rocks suitable in load-bearing structures such as the studied portals. Our study led us to conclude that the most important physical parameter is the thermal dilatation coefficient, because it qualifies the choice of reinforcing and waterproofing products used to prevent further alteration of the stone surface. We recommend that this coefficient is kept constant, otherwise the detatchment of the superficially consolidated layer from the substratum would be unavoidable.

Abstract

Traits related to crop performance (sugar, grain, biomass) are complex and their genetic bases difficult to study. To take advantage, in the process of selection, of tools now provided by molecular genetics, these traits need to be 'dissected' into elemental processes, more simple genetically and less prone to GxE (genotype X environment) interactions (Dingkuhn et al. 2007). However, evaluating a component trait individually is meaningless as plant and crop performance is the dynamic result of physiological, and sometimes genetic, linkages between traits in a given environment. This represents today a great challenge in the context of plant phenotyping and selection. Modelling enables formalizing biological processes as equations with G-dependent parameters, potentially linked to genetic information (eg. QTL). The use of model parameters as phenotypic traits for genetic analyses already showed its relevance in the case of simple models (Reymond et al. 2003; Yin et al. 1999). More recently, a few studies demonstrated the interest of using more integrative plant models for discriminating genotypes, based on parameter values within component, process based modules (Lecoeur et al. 2008; Luquet et al. 2008). Among them is Ecomeristem (Luquet et al. 2006), model simulating cereals' crop performance based on a simple formalism of plant vegetative morphogenesis, i.e. of meristem activity and its GxE regulation (organ creation, size, etc). Its use for QTL detection in a rice mapping population (based on parameters related to tillering, leaf size, phyllochron) gave even promising preliminary results (Ahmadi et al. 2008). DELICAS is a project that aims to identify, for sugar cane, molecular markers associated with genes of yield formation (Nibouche et al. 2010). Crop modelling is intended to support the phenotyping of component processes. In this context, Ecomeristem is currently adapted to sugar cane in order to take advantage of its plant level approach of morphogenesis and source-sink relationships. This paper aims to present this new model version, before it is tested and compared to other modelling approach(es) for its discriminative value (Martiné et al. 2010).

Abstract

In 2000, abnormally high ray fluxes have been detected on some beaches of Camargue. Then, sands of these beaches have been studied from a radiological point of view, showing on the one hand mean levels of uranium-238 and thorium-232 activity about some tens of Bq kg-1, and on the other hand some hot spots with more of 1000 Bq kg-1; and even more on two beaches: one to the east of the Beauduc lighthouse, the other to the east of Espiguette lighthouse. This radioactivity, of natural origin, is responsible of exposure of the public frequenting these two secluded beaches, but nevertheless open to everybody. The Institute for radiological protection and nuclear safety has carried out a dose assessment for people likely to frequent these beaches, taking into account local measurements and samples, in establishing the solubility of sands in the gastric and intestinal fluids, and with assumptions for site frequentation (scenarios). The maximal annual effective dose is about 0.8 mSv for adults and about 0.5 mSv for children; very wise values, in which external exposure widely predominates. © 2008 EDP Sciences.; En 2000, des flux de rayonnement anormalement élevés ont été détectés sur certaines plages du littoral camarguais. Les sables du littoral camarguais ont alors fait l’objet d’une caractérisation radiologique montrant des activités moyennes de quelques dizaines de Bq kg-1 en uranium-238 et thorium-232 d’une part, et l’existence de points chauds à plus de 1000 Bq kg-1 d’autre part ; voire plus sur deux plages : l’une située à l’Est du phare de Beauduc, l’autre située à l’Est du phare de l’Espiguette. Cette radioactivité, d’origine naturelle, est responsable de l’exposition des personnes fréquentant ces deux dernières plages relativement isolées, mais néanmoins accessibles à tout public. L’Institut de radioprotection et de sûreté nucléaire a réalisé une évaluation des doses susceptibles d’être reçues par des personnes fréquentant ces deux dernières plages, en se basant sur des mesures et des prélèvements effectués in situ, en établissant expérimentalement la solubilité des sables dans les fluides gastrique et intestinal, et en formulant des hypothèses sur la fréquentation des lieux (scénarios). La dose annuelle maximale ainsi évaluée est de l’ordre de 0,8 mSv pour des adultes et 0,5 mSv pour les enfants ; valeurs vraisemblablement très prudentes dans lesquelles la dose par exposition externe prédomine largement.

Abstract

Following a radiological accident caused by a gammagraphy source in Chile in December 2005 involving one victim, IRSN was contacted to perform the dosimetric reconstruction of the accident using numerical simulation. Tools developed in the laboratory, associating anthropomorphic mathematic or voxel phantoms with the Monte Carlo calculation code mcnpx, were used in order to determine the dose distribution on the left buttock and absorbed doses to critical organs. The dosimetric mapping show that the absorbed at the skin surface is very high (1900 Gy) but drops rapidly at deep. At a depth of 5 cm, it is 20 Gy. Calculations performed with a mathematical phantom indicate that average doses to the critical organs are relatively low. Moreover, possible bone marrow sites for puncture are identified. Based on the dosimetric mapping, an excision measuring 5 cm in depth by 10 cm in diameter was performed on the left buttock of the victim. © 2007 EDP Sciences.; À la suite d’un accident radiologique dû à une source de gammagraphie survenu au Chili en décembre 2005 et impliquant une victime, l’IRSN a été sollicité pour réaliser la reconstitution dosimétrique par calcul Monte Carlo. Des outils, développés au laboratoire, associant des fantômes anthropomorphes mathématiques et voxélisés au code de calcul Monte Carlo mcnpx ont été mis en œuvre afin de déterminer la distribution de dose au niveau de la fesse gauche de la victime et la dose aux organes critiques. La cartographie dosimétrique réalisée au niveau de la fesse gauche montre que la dose à la surface est importante (1900 Gy) et chute rapidement pour atteindre 20 Gy à 5 cm de profondeur. Les calculs réalisés avec un fantôme mathématique indiquent que les doses moyennes aux organes critiques sont faibles et permettent d’identifier de possibles sites de prélèvement de moelle osseuse. S’appuyant sur la cartographie dosimétrique, une exérèse de 5 cm de profondeur et de 10 cm de diamètre a été pratiquée au niveau de la fesse gauche de la victime.

Abstract

La propagation végétative du cocotier (#Cocos nucifera# L.) par embryogenèse somatique reste une entreprise difficile, due à l'extrême récalcitrance de cette plante à la culture #in vitro#. Parmi les difficultés majeures on peut citer le brunissement intense des tissus maintenus #in vitro#, la lenteur des processus, la difficulté d'obtention d'embryons somatiques capables de germer et la faible vigueur des vitroplants. Pour tenter de comprendre et de lever ces difficultés, six équipes (l'ORSTOM/CIRAD-CP, France ; l'IDEFOR/DPO, Côte d'Ivoire ; le Wye College, Royaume-Uni ; l'Université de Hanovre, Allemagne ; PCA, Philippines et CICY, Mexique) ont initié en 1995 une collaboration sous l'égide de la Communauté Européenne. Au travers de diverses approches, la recherche de l'amélioration du procédé de culture #in vitro#, l'utilisation de différents cultivars, la recherche de marqueurs précoces de l'embryogenèse, l'étude de la physiologie du vitroplant, mais aussi grâce à de nombreux échanges d'informations et de compétences, ce projet vise à accroître les connaissances de la physiologie des tissus de cocotier #in vitro# et à améliorer le protocole de régénération de cette espèce. Le présent article fait état de la stratégie de recherche adoptée en collaboration avec divers partenaires et illustre les principaux résultats obtenus dans le cadre de la réalisation de ce projet.

Abstract

Les seuls espoirs pour parvenir à la propagation végétative du cocotier reposent sur les techniques de culture in vitro et, plus spécifiquement, sur l'embryogenèse somatique. Les premiers résultats de l'approche analytique pluridisciplinaire (phytohormes, histologie, étude de la composition des milieux), obtenus à Montpellier, ont permis à l'équipe ORSTOM/CIRAD de franchir une étape importante : l'obtention reproductible d'embryons complets représentant 5 clones différents. Le franchissement de cette étape fait apparaître de nouveaux facteurs limitants pour la micropropagation du cocotier : - l'absence de prolifération intense des tissus embryogènes, indispensable à la production en masse de vitroplants, - la lenteur du développement des plants régénérés. Les recherches visant à une meilleure connaissance de la physiologie des tissus de cocotier doivent être poursuivies

Abstract

Des clones issus de différents génotypes de cocotier ont été obtenus au laboratoire ORSTOM/CIRAD-CP à Montpellier, France. Cependant, le nombre de ramets regénérés par clone reste faible à cause de l'absence d'une phase de multiplication intense. Ce chapitre résume les différentes étapes du procesus qui ont permis d'aboutir à une embryogenèse somatique: - induction de cals à partir d'explants prélevés sur de jeunes feuilles ou des inflorescences immatures; - étude histologique qui a permis de mettre en évidence deux voies embryogènes; - initiation de l'embryogenèse somatique étudiée sous l'angle des besoins en éléments minéraux nutritifs et en hormones; - enfin énumération des problèmes rencontrés lors de la maturation des embryons et leur conversion en plantules

Abstract

The average lifetime ofB hadrons was measured using data collected with the DELPHI detector at the LEP collider during 1991 and 1992. The measurement was performed using two different anayses. The first method was an improvement on a previous technique, which used charged particle impact parameter distributions. This analysis measured an average lifetime forB hadrons of $$\tau _B = 1.542 \pm 0.021(stat.) \pm 0.045(syst.)ps.$$ (1) The second method was based on a new technique, which used inclusively reconstructed secondary vertices to measure $$\tau _B = 1.599 \pm 0.014(stat.) \pm 0.035(syst.)ps.$$ (2) Taking into account both the statistical and systematic corelations, the results of these two methods were combined to give an average lifetime forB hadrons of $$\tau _B = 1.582 \pm 0.012(stat.) \pm 0.032(syst.)ps.$$ (3)

Abstract

Une étape importante a été atteinte dans la maîtrise de la propagation végétative #in vitro$ du cocotier : obtention reproductible de plantules à partir de 5 clones appartenant à différents génotypes. Deux sortes de tissus prélevés sur des arbres adultes sélectinnés ont été utilisés : explants foliaires et explants inflorenscenciels. La méthode développée comprend les étapes suivantes : induction de la callogénèse sur explants primaires, induction de l'embryogénèse sur les cals obtenus, maturation des embryons et production de plantules. L'étape finale n'a pas été maîtrisée jusqu'à présent. Les embryons obtenus étaient incomplets et dépourvus de méristène caulinaire, obstacle majeur de la méthode au développement d'un procédé de clonage du cocotier. Une approche analytique a permis une meilleure compréhension des causes d'échecs de l'embryogénèse. Ces nouvelles données ont conduit à la production d'embryons complets de façon reproductible, décrits pour la première fois grâce à une étude histologique. Actuellement le travail s'oriente vers la recherche de milieux de culture qui favoriseraient la prolifération intense d'embryons pour une production en masse de plantules. (Résumé d'auteur)

Abstract

Evidence for the production of b-flavoured baryons in Z0 decays is reported from the analysis of 365 000 hadronic events collected by the DELPHI detector. Assuming that most of the weakly decaying b flavoured baryons produced by the Z0 are Λb, the observed signal of View the MathML source pairs, where l is a high transverse momentum lepton in the same jet as the Λ, leads to a production rate: f(b→Λb)×Br(Λb→ΛlνX) = (0.41±0.13±0.09)%. Using a sample of 18 reconstructed Λb decay vertices, the lifetime is determined to be τ(Λb) = (1.04+0.48−0.38±0.10) ps.

Abstract

L'obtention de lignées tissulaires présentant un fort potentiel embryogène a récemment conduit à une meilleure maîtrise de l'embryogenèse somatique chez le cocotier. L'individualisation des cellules embryogènes s'accompagne de changements au niveau du noyau. Les remaniements observés au niveau du noyau permettent une augmentation de la surface de contact entre le noyau et le cytoplasme ce qui favorise probablement les échanges entre ces deux compartiments. Les cellules embryogènes se caractérisent par un épaississement de la paroi pectocellulosique avec fermeture des plasmodesmes (isolement physique). Ces modifications s'accompagnent d'une augmentation de l'activité golgienne avec libération de nombreuses vésicules de type sécrétoire et présence au niveau du plasmalemme, de figures qui rappellent le phénomène d'exocytose. Certains des remaniements infrastructuraux observés transitoirement au cours de l'acquisition de l'aptitude à l'embryogenèse peuvent être rapprochés de ceux qui accompagnent la maturation des cellules gamétiques femelles chez de nombreux végétaux

Abstract

Seven unambiguous events out of a sample of 270 000 Z0 decays, contain in tile same jet a D(s) meson and a muon at large transverse momentum relative to the et axis. These events are direct evidence for B(s)0 meson production in hadronic Z0 decays. The production rate of these events, relative to all hadronic Z0 decays is ( 18 +/- 8) x 10(-5) this number including the relevant branching fractions of the B(s)0 and D(s). The value of the B(s)0 meson lifetime relative to the average B meson lifetime is measured to be 0.8 +/- 0.4.

Abstract

An analysis of the fluctuations in the phase space distribution of hadrons produced in the decay of 78829 Z0 has been carried out, using the method of factorial moments. The high statistics collected by the DELPHI experiment at LEP during 1990 allowed studies of the event sample both globally and in intervals of p(t) and multiplicity, and for different jet topologies and for single jets. A large contribution to the factorial moments of the one-dimensional data on rapidity with respect to the event axis comes from hard gluons. Details of factorial moments in two and three dimensions are presented. Influences of resonance decays have been studied by Monte Carlo simulation: one-dimensional factorial moments at low p(t), and two-, three-dimensional analyses are affected. Parton shower models describe the data reasonably well.

Abstract

Une étape importante vient d'être franchie dans la maîtrise de la multiplication végétative du cocotier : l'obtention de façon reproductible de vitroplants sur 5 clones appartenants à des génotypes différents. Deux sources de tissus prélevés sur individus adultes sont utilisés : explants foliaires et explants inflorescenciels. Le procédé mis en oeuvre comprend les étapes suivantes : callogenèse sur explants primaires, induction de l'embryogenèse sur les cals, maturation des embryons, développement des pousses feuillées et des racines. La production régulière de cals embryogènes et d'embryons somatiques complets a permis leur description histologique

Abstract

A classifier based on a feed-forward neural network has been used for separating a sample of about 123 500 selected hadronic decays of the Z 0 , collected by DELPHI during 1991, into three classes according to the flavour of the original quark pair: u u +d d +s s (unresolved), c c and b b . The classification has been used to compute the partial widths of the Z 0 into b and c quark pairs. This gave Γ c c /Γ h = 0.151 ± 0.008 ( stat. ) ± 0.041 ( syst. ) , Γ b b /Γ h = 0.232±0.005 ( stat. )±0.017 ( syst. ) .

Abstract

A classifier based on a feed-forward neural network has been used for separating a sample of about 123 500 selected hadronic decays of the Z0, collected by DELPHI during 1991, into three classes according to the flavour of the original quark pair: uuBAR + ddBAR + ssBAR (unresolved), ccBAR and bbBAR. The classification has been used to compute the partial widths of the ZO into b and c quark pairs. This gave GAMMA(ccBAR)/GAMMA(h) = 0.151 +/- 0.008 (stat.) +/- 0.041 (syst.), GAMMA(bbBAR)/GAMMA(h) = 0.232 +/- 0.005 (stat.) +/- 0.017 (syst.).

Abstract

International audience; The C70 ARRONAX is a high intensity (up to 2x375uA) multi-particle cyclotron aiming at R&D on material and radiolysis and production of radioisotopes. It began its hands-on phase in December 2010, and is currently undergoing beam lines' modification in experimental halls for present and future experiments. Characterisation of the beams at the end of beamlines is of particular importance to determine the capacity of the cyclotron for end-line experimental users. A program of beam characterisation is being performed based in one hand on dedicated diagnostics e.g. beam profilers, faraday cups, alumina foils and in the other hand on a series of Geant4 beam simulations. The out coming results of the measurements, along with the simulations, are detailed in this report for proton and alpha particle beams, as well as the future prospects of the characterisation program.

Abstract

Creep and crack growth govern the long-term deformability of concrete and thus its service behavior and its durability. The mechanisms involved in the couplings between these effects are not yet clearly identified. The aim of this research was to investigate experimentally and numerically at both the macro and the meso-level (heterogeneous material) the interactions between creep and crack growth in concrete and identify, the main phenomena acting on the overall viscoelastic response of concrete, at various stages of fracture, during relaxations.

Abstract

In 1985 the French government created a unique circuit for the dissemination of doctoral theses: References went to a national database “Téléthèses” whereas the documents were distributed to the university libraries in microform. In the era of the electronic document this French network of deposit of and access to doctoral theses is changing. How do you discover and locate a French thesis today, how do you get hold of a paper copy and how do you access the full electronic text? What are the catalogues and databases referencing theses since the disappearance of “Téléthèses”? Where are the archives, and are they open? What is the legal environment that rules the emerging structures and tools? This paper presents national plans on referencing and archiving doctoral theses coordinated by the government as well as some initiatives for creating full text archives. These initiatives come from universities as well as from research institutions and learned societies. “Téléthèses” records have been integrated in a union catalogue of French university libraries SUDOC. University of Lyon-2 and INSA Lyon developed procedures and tools covering the entire production chain from writing to the final access in an archive: “Cyberthèses” and “Cither”. The CNRS Centre for Direct Scientific Communication at Lyon (CCSD) maintains an archive (“TEL”) with about 2000 theses in all disciplines. Another repository for theses in engineering, economics and management called “Pastel” is proposed by the Paris Institute of Technology (ParisTech), a consortium of 10 engineering and commercial schools of the Paris region.

Abstract

Background Cancer patients are thought to have an increased risk of developing severe Coronavirus Disease 2019 (COVID-19) infection and of dying from the disease. In this work, predictive factors for COVID-19 severity and mortality in cancer patients were investigated. Patients and Methods In this large nationwide retro-prospective cohort study, we collected data on patients with solid tumours and COVID-19 diagnosed between March 1 and June 11, 2020. The primary endpoint was all-cause mortality and COVID-19 severity, defined as admission to an intensive care unit (ICU) and/or mechanical ventilation and/or death, was one of the secondary endpoints. Results From April 4 to June 11, 2020, 1289 patients were analysed. The most frequent cancers were digestive and thoracic. Altogether, 424 (33%) patients had a severe form of COVID-19 and 370 (29%) patients died. In multivariate analysis, independent factors associated with death were male sex (odds ratio 1.73, 95%CI: 1.18-2.52), ECOG PS ≥ 2 (OR 3.23, 95%CI: 2.27-4.61), updated Charlson comorbidity index (OR 1.08, 95%CI: 1.01-1.16) and admission to ICU (OR 3.62, 95%CI 2.14-6.11). The same factors, age along with corticosteroids before COVID-19 diagnosis, and thoracic primary tumour site were independently associated with COVID-19 severity. None of the anticancer treatments administered within the previous 3 months had any effect on mortality or COVID-19 severity, except cytotoxic chemotherapy in the subgroup of patients with detectable SARS-CoV-2 by RT-PCR, which was associated with a slight increase of the risk of death (OR 1.53; 95%CI: 1.00-2.34; p = 0.05). A total of 431 (39%) patients had their systemic anticancer treatment interrupted or stopped following diagnosis of COVID-19. Conclusions Mortality and COVID-19 severity in cancer patients are high and are associated with general characteristics of patients. We found no deleterious effects of recent anticancer treatments, except for cytotoxic chemotherapy in the RT-PCR-confirmed subgroup of patients. In almost 40% of patients, the systemic anticancer therapy was interrupted or stopped after COVID-19 diagnosis., Highlights • A total of 1289 patients with solid tumours and COVID-19 were analysed. • Mortality and COVID-19 severity were mainly driven by patient general characteristics. • Overall, we found no deleterious effects of recent anticancer treatments on mortality. . • Systemic anticancer treatment was interrupted or stopped in 39% of patients.
