    The proportion of female members in The Japanese Association of Anatomists (JAA) is 18% with the proportion of female members higher among the young generation (20-30 Y.O.; 34.8%, 30-40 Y.O.; 26.8%). However, the number of female members in the Board of Directors has been zero or one (0 or 6%) for many years. More than two female members are necessary on the Board to promote the diversity in the management of the JAA. The numbers of female members in other committees has shown gradual increase in recent years. A substantial increase in female faculty members including professors in each university and school will support the future development of the anatomical research field and the association. We have made the first great step by setting up the committee on promotion of gender equality in JAA in March, 2011. In the next year, JAA became a member of Japan Inter-Society Liaison Association Committee for Promoting Equal Participation of Men and Women in Science and Engineering (EPMEWSE). Our committee's activity includes holding workshops and seminars at the annual meetings to promote gender equality in the research field and to encourage mutual support and friendship, not only among women members but also among all members.

    The defense response of the plants against herbivores relies on a complex network of interconnected signaling pathways. In this work, we characterized a new key player in the response of Arabidopsis against the two-spotted spider mite Tetranychus urticae, the MATI (Mite Attack Triggered Immunity) gene. This gene was differentially induced in resistant Bla-2 strain relative to susceptible Kon Arabidopsis accessions after mite attack, suggesting a potential role in the control of spider mites. To study the MATI gene function, it has been performed a deep molecular characterization of the gene combined with feeding bioassays using modified Arabidopsis lines and phytophagous arthropods. The MATI gene belongs to a new gene family that had not been previously characterized. Biotic assays showed that it confers a high tolerance not only to T. urticae, but also to the chewing lepidopteran Spodoptera exigua. Biochemical analyses suggest that MATI encodes a protein involved in the accumulation of reducing agents upon herbivore attack to control plant redox homeostasis avoiding oxidative damage and cell death. Besides, molecular analyses demonstrated that MATI is involved in the modulation of different hormonal signaling pathways, affecting the expression of genes involved in biosynthesis and signaling of the jasmonic acid and salicylic acid hormones. The fact that MATI is also involved in defense through the modulation of the levels of photosynthetic pigments highlights the potential of MATI proteins to be exploited as biotechnological tools for pest control.

    The Resonance-enhanced two-photon ionization (R2PI) and Mass-analyzed threshold ionization (MATI) spectra of 4-chloro-3-fluoroanisole (4Cl3FA) were recorded in detail. The experimental and calculated results revealed that cis and trans 4Cl3FA are the only two stable conformers in each of the S0, S1 and D0 states. The first electronic excitation energies (E1's) of cis and trans35Cl-4Cl3FA were measured to be 35,326 ± 3 and 35,443 ± 3 cm-1 by the R2PI spectroscopy and the corresponding adiabatic ionization energies (IEs) were determined to be 67,330 ± 5 and 67,591 ± 5 cm-1 by the MATI spectroscopy. The E1's and IEs of cis and trans37Cl-4Cl3FA were also obtained and found to be identical to that of the 35Cl-4Cl3FA conformers. Compared with the trans 4Cl3FA, the cis 4Cl3FA is more stable in the S0, S1 and D0 states. The vibrational bands observed in the R2PI and MATI spectra are related to the vibrations involving the in-plane deformation of the benzene ring, the CH3 torsion and the OCH3 inversion. The substituent effects on the molecular structures, transition energies and vibrations of 4Cl3FA are discussed.

    2017-10-01

    An improved detection scheme is presented for threshold ionization spectroscopy with simultaneous recording of the Zero Electron Kinetic Energy (ZEKE) and Mass Analysed Threshold Ionisation (MATI) signals. The objective is to obtain accurate dissociation energies for larger molecular clusters by simultaneously detecting the fragment and parent ion MATI signals with identical transmission. The scheme preserves an optimal ZEKE spectral resolution together with excellent separation of the spontaneous ion and MATI signals in the time-of-flight mass spectrum. The resulting improvement in sensitivity will allow for the determination of dissociation energies in clusters with substantial mass difference between parent and daughter ions.

    In the framework of the French National Research Agency program on nuclear safety and radioprotection, the `DIstributed Sensing for COrium Monitoring and Safety' project aims at developing innovative instrumentation for corium monitoring in case of severe accident in a Pressurized Water nuclear Reactor. Among others, a new under-vessel instrumentation based on Self-Powered Neutron Detectors is developed using a numerical simulation toolbox, named `MATiSSe'. The CEA Instrumentation Sensors and Dosimetry Lab developed MATiSSe since 2010 for Self-Powered Neutron Detectors material selection and geometry design, as well as for their respective partial neutron and gamma sensitivity calculations. MATiSSe is based on a comprehensive model of neutron and gamma interactions which take place in Selfpowered neutron detector components using the MCNP6 Monte Carlo code. As member of the project consortium, the THERMOCOAX SAS Company is currently manufacturing some instrumented pole prototypes to be tested in 2017. The full severe accident monitoring equipment, including the standalone low current acquisition system, will be tested during a joined CEA-THERMOCOAX experimental campaign in some realistic irradiation conditions, in the Slovenian TRIGA Mark II research reactor.

    Juxtarenal aortic aneurysms (JAA) account for approximately 15% of abdominal aortic aneurysms. Fenestrated endovascular aneurysm repair (FEVAR) and chimney endovascular aneurysm repair (CH-EVAR) are both effective methods to treat JAAs, but the comparative effectiveness of these treatment modalities is unclear. We searched the PubMed, Medline, Embase, and Cochrane databases to identify English language articles published between January 2005 and September 2013 on management of JAA with fenestrated and chimney techniques to conduct a systematic review to compare outcomes of patients with juxtarenal aortic aneurysm (JAA) treated with the two techniques. We compared nine F-EVAR cohort studies including 542 JAA patients and 8 CH-EVAR cohorts with 158 JAA patients regarding techniques success rates, 30-day mortality, late mortality, endoleak events and secondary intervention rates. The results of this systematic review indicate that both fenestrated and chimney techniques are attractive options for JAAs treatment with encouraging early and mid-term outcomes. PMID:26869488

    The baseline sample used in this work is formed by 1111 FGK stars observed within the context of the HARPS GTO programs. It is a combination of three HARPS subsamples hereafter called HARPS-1 (Mayor et al., 2003Msngr.114...20M), HARPS-2 (Lo Curto et al., 2010, Cat. J/A+A/512/A48), and HARPS-4 (Santos et al., 2011, Cat. J/A+A/526/A112). The individual spectra of each star were reduced using the HARPS pipeline and then combined with IRAF after correcting for its radial velocity shift. The final spectra have a resolution of R~115000 and high signal-to-noise ratios (55%of the spectra have a S/N higher than 200). The total sample is composed of 136 stars with planets and 975 stars without detected planets. Chemical abundances of these samples for refractory elements with A<29 can be found in Adibekyan et al. (2012, Cat. J/A+A/545/A32) together with oxygen (Bertran de Lis et al., 2015, Cat. J/A+A/576/A89), carbon (Suarez-Andres et al., 2017, Cat. J/A+A/599/A96), lithium (Delgado Mena et al., 2014, Cat.

    The growth of Si{1-x}Gex layers at a high temperature (1300 K) and low pressure (315 Pa) (by chemical vapour deposition) was studied by a thermodynamic approach and a mass transport analysis using simplifying assumptions. The results showed that the thermodynamic analysis does not permit alone to explain the experimental measurements concerning the composition of the layer. The mass transport analysis showed that thermodiffusion would be of importance on layer composition and uniformity for large substrates. La croissance de couches de Si{1-x}Gex à haute température (1300 K) et basse pression (315 Pa) par réaction chimique à partir d'une phase gazeuse a été étudiée à l'aide d'une approche thermodynamique et de l'analyse du transfert de matière pour laquelle des hypothèses très simplificatrices ont été émises. Les résultats ont montré que l'analyse thermodynamique, seule, ne permet pas d'interpréter les mesures concernant la composition du matériau déposé. Quant à l'étude du transfert de matière, elle a montré que la thermodiffusion jouait un rôle important sur la composition du matériau déposé ainsi que sur l'uniformité du dépôt sur des substrats de grandes dimensions.

    Videometric measurements of changes in vessel lumen diameters were made to investigate autoregulatory and tubuloglomerular feedback (TGF) responses of early efferent arterioles (EA), mid-to-late afferent arterioles (MAA), and terminal, juxtaglomerular afferent arterioles (JAA) in rat juxtamedullary nephrons in vitro. High-contrast shadow-cast images of blood-perfused arterioles at the glomerular vascular pole were obtained with incident illumination and long-working-distance objectives fitted to a compound microscope. In response to an increase in blood perfusion pressure from 60 to 140 mmHg, strong autoregulatory vasoconstriction was observed in the MAA and JAA, with respective reductions in mean luminal diameter of 23 +/- 4 and 40 +/- 4% (mean +/- SE); EA diameter was unchanged. In response to TGF excitation by direct microinjection of Ringer solution into the cortical thick ascending limb segment near the macula densa, JAA luminal diameter decreased by 34 +/- 5%. The TGF responses were completely inhibited by the addition of 0.1 mM furosemide to the tubular injectate. Calcium channel blockade achieved by adding 1 microM nimodipine to the superfusate had no effect on early EA diameter but produced a blood pressure-dependent JAA and MAA vasodilation and complete inhibition of autoregulatory responses. These results provide direct evidence that the distal afferent arteriole in juxtamedullary nephrons is a major effector site for both renal autoregulation and tubuloglomerular feedback.

    The catalogue of variable stars in open clusters were prepared by cross-matching of Variable Stars Index (http://www.aavso.org/vsx) version Apr 29, 2012 (available online, Cat. B/vsx) against the version 3.1. catalogue of open clusters DAML02 (Dias et al. 2002A&A...389..871D, Cat. B/ocl) available on the website http://www.astro.iag.usp.br/~wilton. The open clusters were divided into two categories according to their size, where the limiting diameter was 60 arcmin. The list of all suspected variables and variable stars located within the fields of open clusters up to two times of given cluster radius were generated (Table 1). 8938 and 9127 variable stars are given in 461 "smaller" and 74 "larger" clusters, respectively. All found variable stars were matched against the PPMXL catalog of positions and proper motions within the ICRS (Roeser et al., 2010AJ....139.2440R, Cat. I/317). Proper motion data were included in our catalogue. Unfortunately, a homogeneous data set of mean cluster proper motions has not been available until now. Therefore we used the following sources (sorted alphabetically) to compile a new catalogue: Baumgardt et al. (2000, Cat.

    2008-01-01

    European aviation is moving into an exciting phase now, the administrative structure is changing. Aviation rules and aviation medicine will get a new structure as well. The nature of air traffic required an international scope in rulemaking – especially in such a confined continent as Europe with 41 countries, about 380 Million inhabitants and 317 billion person kilometres flown each year. For economic reasons it became necessary to develop common standards for certification of aircraft in the beginning of the 1970ies, maintenance followed later on. The Cyprus arrangement of 01 July 1990 created the JAA (Joint Aviation Authorities). Joint Aviation Requirements were drafted to replace existing national provisions and have been implemented from the end of the 1990ies. The areas of air operations and pilot licensing have been covered as well. The latter comprises of aviation medicine as well. The implementation of JAR-FCL 3, which covers the medical requirements for pilots, started from 1999 on in the several JAA member states. A detailed overview about development and structure of JAA, tools for harmonisation, rulemaking and amendment of requirements, medical standards, review procedures for contentious or marginal cases is described. Shortcomings were the fact that implementation was left to the discretion of the member states and that JAA had no executive power. This resulted in differences in safety and the EU commission concluded that aviation safety had to be regulated by the EU commission. After adoption of EU regulation 1592/2002 in 2002 common and binding requirements were to be drafted and a European aviation agency to be founded. EASA (European Aviation Safety Agency) started its work in September 2003. Finally it will take over the role of JAA completely. Whereas Certification and Maintenance were in the focus first, Flight Operations and Licensing are going to be covered as well in the near future. Essential Requirements have been drafted, outlining

    In many countries there are now detailed Child Death Review (CDR) processes following unexpected child deaths. CDR can lead to a fuller understanding of the causes for each child's death but this potentially intrusive process may increase the distress of bereaved families. In England, a joint agency approach (JAA) is used where police, healthcare and social services investigate sudden child deaths together and a key part of this is the joint home visit (JHV) where specialist police and paediatricians visit the home with the parents to view the scene of death. This study aimed to learn of bereaved parents' experiences of JAA investigation following Sudden Unexpected Death in Infancy (SUDI). This was a qualitative study of joint agency investigation of SUDI by specialist police, healthcare and social services including case note analysis, parental questionnaires, and in-depth interviews with parents and professionals. Families were recruited at the conclusion of the JAA. Data were analysed using a Framework Approach. 21/113 eligible families and 26 professionals participated giving theoretical saturation of data. There was an inherent conflict for professionals trying to both investigate deaths thoroughly as well as support families. Bereaved parents appreciated the JAA especially for the information it provided about the cause of death but were frustrated with long delays waiting to obtain this. Many parents wanted more emotional support to be routinely provided. Most parents found the JHV helpful but a small minority of mothers found this intensely distressing. In comparison to JHVs, when police visited death scenes without paediatricians, information was missed and parents found these visits more upsetting. There were issues with uniformed non-specialist police traumatising parents by starting criminal investigations and preventing parents from accessing their home or collecting vital possessions. Overall most parents feel supported by professionals during the JAA

    Gender equality activity in the Bioimaging Society was initiated in 2005 when it joined the Japan Inter-Society Liaison Association Committee for Promoting Equal Participation of Men and Women in Science and Engineering (EPMEWSE). The Gender Equality Committee of the Bioimaging Society is acting on this issue by following the policy of the EPMEWSE, and has also been planning and conducting lectures at annual meetings of the society to gain the understanding, consents, and cooperation of the members of the society to become conscious of gender equality. Women's participation in the society has been promoted through the activities of the Gender Equality Committee, and the number of women officers in the society has since increased from two women out of 40 members in 2005 to five out of 44 in 2013. The activities of the Gender Equality Committee of the Japanese Association of Anatomists (JAA) have just started. There are more than 400 women belonging to the JAA. When these women members join together and collaborate, women's participation in the JAA will increase.

    Most outputs of massive star evolution critically depend on the mass loss rates. In order to broaden the comparison basis and to illustrate the effects of different mass loss rates, we have computed new sets of models, with initial masses between 12 and 120 M⊙, and metallicities, Z, between 0.001 and 0.040, with a mass loss rate increased by a factor of two during the phases when the stellar winds are believed to be essentially driven by the radiation pressure. A moderate core-overshooting and the new radiative opacities from Iglesias et al. (1992ApJ...397..717I) and Kurucz (1991) were taken into account. These models complete the homogeneous and extended theoretical database formed by the previous grids of this series, computed by Schaller et al. (1992, Cat. J/A+AS/96/269) for Z=0.020 and Z=0.001, by Schaerer et al. (1992, Cat. J/A+AS/98/523; 1993, Cat. J/A+AS/102/339) for Z=0.008 and Z=0.040 and by Charbonnel et al. (1993, Cat. J/A+AS/101/415) for Z=0.004. This paper closes this series. Of particular interest is the predicted behaviour of metal rich stars such as may be found in the inner regions of our Galaxy. New evolutionary connexions are found, in particular we show that the most massive and metal rich stars may spend a relatively long time as He and N enriched stars and may even end their evolution as white dwarfs.

    We study here the magnetic properties of Y- and Lu- Iron Garnets using the Bethe- Peierls-Weiss method modified to suit complex systems like these Garnets. We consider these Garnets as described by Heisenberg Hamiltonian with two sublattices (a,d) and determine the exchange interaction parameters Jad, Jaa and Jdd by matching the exerimental susceptibility curves. We find Jaa and Jdd to be much smaller than those determined by Néel theory, and consistent with those obtained by the study of spin wave spectra; the spin wave dispersion relation constant obtained using these parameters gives good agreement with the experimental values.

    2009-01-01

    Multi-Mission Automated Task Invocation Subsystem (MATIS) is software that establishes a distributed data-processing framework for automated generation of instrument data products from a spacecraft mission. Each mission may set up a set of MATIS servers for processing its data products. MATIS embodies lessons learned in experience with prior instrument- data-product-generation software. MATIS is an event-driven workflow manager that interprets project-specific, user-defined rules for managing processes. It executes programs in response to specific events under specific conditions according to the rules. Because requirements of different missions are too diverse to be satisfied by one program, MATIS accommodates plug-in programs. MATIS is flexible in that users can control such processing parameters as how many pipelines to run and on which computing machines to run them. MATIS has a fail-safe capability. At each step, MATIS captures and retains pertinent information needed to complete the step and start the next step. In the event of a restart, this information is retrieved so that processing can be resumed appropriately. At this writing, it is planned to develop a graphical user interface (GUI) for monitoring and controlling a product generation engine in MATIS. The GUI would enable users to schedule multiple processes and manage the data products produced in the processes. Although MATIS was initially designed for instrument data product generation,

    Endovascular aneurysm repair (EVAR) of juxtarenal aortic aneurysms (JAA) is particularly challenging owing to the requirement of suprarenal EVAR graft fixation, which has been associated with significant declines in long term renal function. Therefore, the ability to design fenestrated EVAR grafts on a personalized basis in order to ensure visceral and renal perfusion, is highly desirable. The objectives of this study are: a) To demonstrate novel 3D geometric methods to virtually design and deploy EVAR grafts into a virtually designed JAA, by applying a custom surface mesh deformation tool to a patient-specific descending aortic model reconstructed from computed tomographic (CT) images; and b) To virtually evaluate patient-specific renal flow and wall stresses in these patient-specific virtually EVAR geometries, using computational fluid dynamics (CFD). The presented framework may provide the modern cardiovascular surgeon the ability to leverage non-invasive, pre-operative imaging equipment to personalize and guide EVAR therapeutic strategy. Our CFD studies revealed that virtual EVAR grafting of a patient-specific JAA, with optimal fenestration sites and renal stenting, led to a 179.67±15.95% and 1051.43±18.34% improvement in right and left renal flow rates, respectively, when compared with the baseline patient-specific aortic geometry with renal stenoses, whereas a right and left renal flow improved by 36.44±2.24% and 885.93±12.41%, respectively, relative to the equivalently modeled JAA with renal stenoses, considering averages across the three simulated inflow rate cases. The proposed framework have utility to iteratively optimize suprarenal EVAR fixation length and achieve normal renal wall shear stresses and streamlined juxtarenal hemodynamics.

    The aim of the current study was the evaluation of biofilm development on different implant surfaces. Initial biofilm formation was investigated on five different implant surfaces, machined titanium (MTi), modified machined acid-etched titanium (modMATi), machined titanium zirconium (MTiZr), modified machined and acid-etched titanium zirconium (modMATiZr) and sandblasted large grid and acid-etched titanium zirconium surface (SLATiZr) for 24 and 48 h. Biocompatibility was tested after tooth brushing of the samples via cell viability testing with human gingival fibroblasts. After 24 h of biofilm collection, mean plaque surface was detected in the following descending order: After 24 h: MTiZr > MTi > SLATiZr > modMATiZr > modMATi. Both M surfaces showed significant higher biofilm formation than the other groups. After 48 h: MTiZr > MTi > SLATiZr > modMATiZr > modMATi. After tooth brushing: SLATiZr > modMATi > modMATiZr > MTi > MTiZr. All native samples depicted significant higher cell viability than their corresponding surfaces after biofilm removal procedure. The TiZr groups especially the modMATiZr group showed slower and less biofilm formation. In combination with the good biocompatibility, both modMA surfaces seem to be interesting candidates for surfaces in transgingival implant design. © 2016 John Wiley & Sons A/S.

    Les feldspaths sont répandus dans l'écorce terrestre mais seuls les feldspaths potassiques et sodiques sont très recherchés dans l'industrie céramique et verrière. Pour qu'ils soient utilisables, ces matériaux doivent contenir très peu d'impuretés nocives de fer et surtout de silice. La carrière d'Ain-Barbar exploite la matière feldspathique de teneurs moyennes respectives 74,5% SiO{2}, 9,5% 12,75% Al{2}O{3}, 1,30% Fe{2}O{3} et 9,5 K{2}O (0,90% Na{2}O). Toutefois, on constate un taux très élevé en quartz ce qui diminue la valeur du produit marchand et une teneur élevée en fer ce qui donne au produit fabriqué, des aspects de coloration le rendant impropre à la commercialisation. A cet effet, une caractérisation minéralogique et chimique a été réalisée sur une série d'échantillons prélevés du site d'extraction de la substance utile. Des essais de préconcentration granulométrique ont montré qu'un classement dimensionnel peut offrir une qualité de produits acceptables par les céramistes.

This project is performed with Mopra, a 22m single-dish radio telescope located near Coonabarabran in New South Wales, Australia. The angular resolution of Mopra is 38", with a beam efficiency between 0.49 at 86GHz and 0.42 at 115GHz. The pointing accuracy of the main MALT90 maps is about 8", and the absolute flux uncertainty is in the range of 10%-17% depending on the transition in question. The target clumps of this survey are selected from the 870um Atacama Pathfinder Experiment (APEX) Telescope Large Area Survey of the Galaxy (ATLASGAL; Schuller+ 2009A&A...504..415S; Contreras+ 2013, J/A+A/549/A45; superseded by J/A+A/568/A41).

    Our baseline sample is 1111 FGK stars observed within the context of the HARPS GTO programs. It is a combination of three HARPS subsamples hereafter called HARPS-1 (Mayor et al., 2003Msngr.114...20M), HARPS-2 (Lo Curto et al., 2010, Cat. J/A+A/512/A48), and HARPS-4 (Santos et al., 2011, Cat. J/A+A/526/A112). The individual spectra of each star were reduced using the HARPS pipeline and then combined with IRAF2 after correcting for its radial velocity shift. The final spectra have a resolution of R~110000 and high signal-to-noise ratio (55% of the spectra have a S/N higher than 200). The total sample is composed of 135 stars with planets and 976 stars without detected planets. (4 data files).

    In an editorial earlier this year (JAAS, 22, 111, 2007), we opined that metallomics, the study of metals in biological systems, would be an increasingly important topic in elemental analysis in general and for this journal in particular . This issue of the journal, co-edited by the two of us, is a second special issue covering the subject of Metallomics (the first issue was JAAS, 19/1, 2004). The present issue is comprised of technique, application, and perspective papers that address this emerging field of study and show how atomic spectrometry is contributing to the understanding of biological systems. The subjectsmore » covered range from metal binding in plants through investigations of metal and metalloids in samples of biological fluids to the study of food supplements and drug interactions in cells. The issue includes two Critical Reviews. Yuxi Gao and colleagues discuss advanced nuclear analytical techniques for the emerging field of metalloproteomics. While Laura Liermann and her colleagues consider how micro-organisms extract metals from minerals in the environment for utilization in metabolic processes. The content of some of these papers stretches the traditional boundaries and scope of this journal, as echoed by the reviewers of some of the papers. This discussion about scope requires perhaps further debate. However, it is our view that while the Journal must remain true to its core aims, it must also strive to accommodate and motivate a wider authorship and readership. Metallomics is a field that transcends biology and microbiology, biochemistry, clinical chemistry, environmental chemistry, geochemistry, and yes, atomic spectroscopy. If JAAS aspires to be a leading force in metallomics, the Journal must expand its horizons beyond traditional analytical spectroscopy per se. Accordingly, in this special issue you will find papers that have a heavy clinical emphasis, which speak to complementary (non-atomic) spectroscopic techniques, and that provide

    The photometry used in this paper comes from two sources. In the case of NGC 5617, modern CCD photometry in the UBVI passbands is available from Carraro (2011, Cat. J/A+A/536/A101). For Trumpler 22, only old photographic data exist (Haug, 1978A&AS...34..417H), and for this reason we exploit here a new data set. Photometry in UBVI was acquired at Las Campanas Observatory on the nights from 2011 June 03 and are published here for the first time. We stress that this setup (telescope/instrument) is the same that Carraro (2011, Cat. J/A+A/536/A101) used for NGC 5617. Spectra were collected on the 3.9 m Anglo-Australian Telescope (AAT) using the UCLES spectrograph (2012 March 5-6) and using the HERMES multi-object spectrograph (2014 August 22) under service observation time.

    For over 25 years zero kinetic energy (ZEKE) spectroscopy has yielded a rich foundation of high-resolution results of molecular ions. This was based on the discovery in the late 60's of long-lived ion states throughout the ionization continuum of molecular ions. Here, an example is chosen from another fundamental system pioneered at this university. The mass-analyzed threshold ionization (MATI) spectra of jet-cooled chromium bisarene complexes (η(6)-RPh)(2)Cr (R = Me (1), Et (2), i-Pr (3), and t-Bu (4)) have been measured and interpreted on the basis of DFT calculations. The MATI spectra of complexes 1 and 2 appear to reveal features arising from ionizations of the isomers formed by the rotation of one arene ring relative to the other. The 1 and 2 MATI spectra show two intense peaks corresponding to the 0(0)(0) ionizations with inverse intensity ratios. As indicated by the DFT calculations, the intensity ratio change on going from 1 to 2 results from different isomers contributing to each MATI peak. The ionization energies corresponding to the 0(0)(0) peaks are 42746 ± 5 and 42809 ± 5 cm(-1) for compound 1 and 42379 ± 5 and 42463 ± 5 cm(-1) for complex 2. The 1 and 2 spectra show also the weaker features representing transitions to the vibrationally excited cationic levels, the signals of individual rotamers being detected and assigned on the basis of calculated vibrational frequencies. The MATI spectra of compounds 3 and 4 reveal only one strong peak because of close ionization potentials of the isomers contributing to the MATI signal. The 3 and 4 ionization energies are 42104 ± 5 and 41917 ± 5 cm(-1), respectively. The precise values of ionization energies obtained from the MATI spectra reveal a nonlinear dependence of the IE on the number of Me groups in the alkyl substituents of (η(6)-RPh)(2)Cr. This can be explained by an increase in the molecular zero point energies on methylation of the substituents.

    WIde-field Nearby Galaxy-cluster Survey (WINGS) is a large survey targeting 76 clusters of galaxies selected on the basis of their X-ray luminosity (Ebeling et al. 1996, Cat.

The original WINGS data set consisted of B and V deep photometry of a 34'*34' field of view with the WFC@INT and the WFC@2.2mMPG/ESO (Varela et al. 2009, Cat. J/A+A/497/667), spectroscopic follow-ups with 2dF@AAT and WYFFOS@WHT (Cava et al. 2009, Cat. J/A+A/495/707), plus J and K imaging with WFC@UKIRT (Valentinuzzi et al. 2009, Cat. J/A+A/501/851) and some U-band imaging (Omizzolo et al. 2014, Cat. J/A+A/561/A111). This database is presented in Moretti et al. 2014A&A...564A.138M and has been employed for a number of studies (see https://sites.google.com/site/wingsomegawings/). OmegaCAM-VST observations of WINGS galaxy clusters (OMEGAWINGS) is a recent extention of this project, that quadruples the area covered (1deg2) and allows to reach up to ~2.5 cluster virial radii. OMEGAWINGS is based on two OmegaCAM@VST GTO programs for 46 WINGS clusters: a B and V campaign completed in P93, and an ongoing u-band programme. The B and V data, the data reduction and the photometric catalogs are presented in Gullieuszik et al. 2015 (Cat. J/A+A/581/A41). Spectra are obtained with AAOmega@AAT on the OmegaCAM field. So far, we have secured high quality spectra for ~30 OMEGAWINGS clusters, reaching very high spectroscopic completeness levels for galaxies brighter than V=20 from the cluster cores to their periphery (A. Moretti et al. 2016, in preparation). Galaxies are considered cluster members if they are within 3σ from the cluster redshift. The mean redshift uncertainty, computed from the differences between WINGS and OMEGAWINGS redshift values of repeated objects, is Δz=0.0002. For this

    Acculturation is the phenomenon of the attitudinal changes of individuals who come into continuous contact with another culture. Despite the long history of Japanese immigration to America, little is known about the impact of acculturation on perceptions of a good death. To examine differences in perceptions of a good cancer death among Japanese Americans (JA/A), Japanese living in America (J/A), and the Japanese living in Japan (J/J). We administered surveys among JA/A and J/A and used historical J/J data for reference. Primary endpoint was the proportion of respondents who expressed the necessity of core and optional items of the Good Death Inventory. Group differences ≥20% were deemed clinically important. In total, 441 survey responses in America and 2548 in Japan were obtained. More than 80% of respondents consistently considered nine of 10 core items necessary without significant group differences. No core item reached a ≥20% group difference. Three of the eight optional items reached ≥20% group difference: fighting against disease until one's last moment (49%, P < 0.0001; 52%, P < 0.0001; and 73% in JA/A, J/A, and J/J, respectively), knowing what to expect about one's condition in the future (83%, P < 0.0001; 80%, P < 0.0001; and 58%, respectively), and having faith (64%, P = 0.0548; 43%, P = 0.0127; and 38%, respectively). Although most core items of a good death were preserved throughout the levels of acculturation, perceptions of some optional items shifted away from Japanese attitudes as individuals became more acculturated. Understanding of different levels of acculturation may help clinicians provide culturally sensitive end-of-life care. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    Fusarium head blight (FHB) is a destructive wheat disease present throughout the world, and host resistance is an effective and economical strategy used to control FHB. Lack of adequate resistance resource is still a main bottleneck for FHB genetics and wheat breeding research. The synthetic-derived bread wheat line C615, which does not carry the Fhb1 gene, is a promising source of FHB resistance for breeding. A population of 198 recombinant inbred lines (RILs) produced by crossing C615 with the susceptible cultivar Yangmai 13 was evaluated for FHB response using point and spray inoculations. As the disease phenotype is frequently complicated by other agronomic traits, we used both traditional and multivariate conditional QTL mapping approaches to investigate the genetic relationships (at the individual QTL level) between FHB resistance and plant height (PH), spike compactness (SC), and days to flowering (FD). A linkage map was constructed from 3,901 polymorphic SNP markers, which covered 2,549.2 cM. Traditional and conditional QTL mapping analyses found 13 and 22 QTL for FHB, respectively; 10 were identified by both methods. Among these 10, three QTL from C615 were detected in multiple years; these QTL were located on chromosomes 2AL, 2DS, and 2DL. Conditional QTL mapping analysis indicated that, at the QTL level, SC strongly influenced FHB in point inoculation; whereas PH and SC contributed more to FHB than did FD in spray inoculation. The three stable QTL (QFhbs-jaas.2AL, QFhbp-jaas.2DS, and QFhbp-jaas.2DL) for FHB were partly affected by or were independent of the three agronomic traits. The QTL detected in this study improve our understanding of the genetic relationships between FHB response and related traits at the QTL level and provide useful information for marker-assisted selection for the improvement of FHB resistance in breeding.

  20. Exchange stiffness of Ca-doped YIG

    NASA Astrophysics Data System (ADS)

    Avgin, I.; Huber, D. L.

    1994-05-01

    An effective medium theory for the zero-temperature exchange stiffness of uncompensated Ca-doped YIG is presented. The theory is based on the assumption that the effect of the Ca impurities is to produce strong, random ferromagnetic interactions between spins on the a and d sublattices. In the simplest version of the theory, a fraction, x, of the ad exchange integrals are large and positive, x being related to the Ca concentration. The stiffness is calculated as function of x for arbitrary perturbed ad exchange integral, Jxad. For Jxad≳(1/5)‖8Jaa+3Jdd‖, with Jaa and Jdd denoting the aa and dd exchange integrals, respectively, there is a critical concentration, Xc, such that when x≳Xc, the stiffness is complex. It is suggested that Xc delineates the region where there are significant departures from colinearity in the ground state of the Fe spins. Extension of the theory to a model where the Ca doping is assumed to generate Fe4+ ions on the tetrahedral sites is discussed. Possible experimental tests of the theory are mentioned.

J/A+A/570/A65, Paper I) and Koenig et al. (2017, Cat. J/A+A/599/A139, Paper III). These clumps consist almost entirely of clumps that have the potential to form, or are forming, massive stars. Our observations were carried out on 2013 July and December, 2014 September and November, and 2015 April, June, July, and October with the Atacama Pathfinder EXperiment (APEX) 12m telescope located on Chajnantor (Chile). Five transitions of H2CO (J=3-2) were observed with the new MPIfR 1-mm receiver (PI230) with a beam size from 27.6" to 29.5" and integration times of 1 to 3 minutes. Five H2CO (J=4-3) transitions were observed with the FLASH receiver with a beam size ~21.4" and integration times of 2 to 4 minutes. (7 data files).

    We first selected high-quality samples from the 2MAst and UCAC4 catalogues for comparison and verification of the proper motions. For 441 circular proper motion bins (radius 15mas/yr) within+/-50mas/yr, the sky outside a thin Galactic plane zone (|b|<5°) was binned in small areas ('sky pixels') of 0.25x0.25°2, Sky pixels with enhanced numbers of stars with a certain common proper motion in both catalogues were considered as cluster candidates. In total we discovered 692 density enhancements (regarded as cluster candidates). These candidates were cross-identified with known objects. Unidentified objects were passed through the standard MWSC pipeline (described in Kharchenko et al., 2012, Cat. J/A+A/543/A156) for verification, cluster membership construction and structure, kinematic and astrophysical parameter determination. The basic stellar data were taken from the all-sky catalogue 2MAst (2MASS with Astrometry), that was extracted from the all-sky catalogues PPMXL (Roeser et al. 2010, Cat.) and 2MASS (Cutri et al. 2003, Cat.). We found that 355 candidates coincide or overlap with known objects. From the remaining candidates, 270 could not be confirmed by the MWSC pipeline, whereas 63 were classified as real star clusters, for which we determined their basic cluster parameters. Around each confirmed object from our target list we defined a circular area with a radius of ra=r2+radd where r2 is an initial estimate of the cluster radius, and radd=0.3deg. In these areas we selected in 2MAst only those stars with flags Rflg (the 2nd triple of the flags in 2MASS) set to 1, 2, or 3 in each band, i.e. the stars with the best quality detections in photometric and astrometric data. The 63 sky areas with confirmed clusters contain about 0.49 mln 2MAst stars with best quality detections in photometric and astrometric data. We selected most probable members and determined - with a homogeneous method/pipeline - angular sizes of the main morphological parts

    The magnetic susceptibility of rare-earth (Y and Lu) iron garnets is studied using a modified Bethe-Peierls-Weiss (BPW) approximation. The modifications enable us to incorporate the three exchange parameters Jad, Jaa and Jdd necessary to describe the systems. We get excellent fits to the experimental susceptibilities from which we determined the J-values. These also give excellent agreement with the spin wave dispersion relation constant D.

    We obtained ALMA observations of every source in Chamaleon I detected in the single-dish 870 μm LABOCA survey by Belloche et al. (2011, J/A+A/527/A145), except for those listed as likely artifacts (1 source), residuals from bright sources (7 sources), or detections tentatively associated with YSOs (3 sources). We observed 73 sources from the initial list of 84 objects identified by Belloche et al. (2011, J/A+A/527/A145). We observed the 73 pointings using the ALMA Band 3 receivers during its Cycle 1 campaign between 2013 November 29 and 2014 March 08. Between 25 and 27 antennas were available for our observations, with the array configured in a relatively compact configuration to provide a resolution of approximately 2" FWHM (300 AU at the distance to Chamaeleon I). Each target was observed in a single pointing with approximately 1 minute of on-source integration time. Three out of the four available spectral windows were configured to measure the continuum at 101, 103, and 114 GHz, each with a bandwidth of 2 GHz, for a total continuum bandwidth of 6 GHz (2.8 mm) at a central frequency of 106 GHz.

According to the AGN unification scheme (Antonucci, 1993ARA&A..31..473A; Urry & Padovani, 1995PASP..107..803U), FSRQ and BL Lacs are those AGN whose relativistic jets point towards the Earth. Observations were made with the Nordic Optical Telescope (NOT) at La Roque de los Muchachos, La Palma, Canarias, Spain. They were conducted between 2011 May 09 and September 15 using the near-infrared Camera (NOTCam)3 on the NOT. NOTcam field of view is 4'x4' with a pixel scale of 0.234-arcsec/pixel designed to be used in the range from 0.8 to 2.5um in the bands J, H and K. (1 data file).

    The first VLBI (Very Long Baseline Interferometry) observing campaign in 2007 resulted in the detection of 398 targets with the European VLBI Network (EVN; Bourda et al., 2010, cat. J/A+A/520/A113). During the second observing campaign, a subset of 105 sources detected in the previous campaign was observed (Bourda et al., 2011, cat. J/A+A/526/A102). Their positions were derived by Petrov (2011, cat. J/AJ/142/105) and formed the OBRS-1 (Optically Bright extragalactic Radio Sources) catalog. The remaining sources were observed in the third campaign, called OBRS-2. During the OBRS-2 campaign, there were three observing sessions with 10 VLBA (Very Long Baseline Array) stations and 5-6 EVN stations from this list: EFLSBERG, MEDICINA, ONSALA60, YEBES40M, DSS63, HARTRAO, and NOTO. Observations were made on 2010 Mar 23 (session ID gc034a), on 2011 Nov 8 (gc034bcd), and on 2011 Mar 15 (gc034ef). The OBRS-2 catalog presents precise positions of the 295 extragalactic radio sources as well as median correlated flux densities at 8.4 and 2.2GHz at baseline lengths shorter than 900km and at baseline lengths longer than 5000km.

    Coordinates and photometric parameters (magnitudes and colours) are presented of the stars located in a molecular condensation on the SW-border of the Galactic HII region Sh2-217. The data were obtained on January 4, 2004 with the 3.58-m Telescopio Nazionale Galileo (TNG; La Palma, Canary Islands, Spain). Near-infrared observations were carried out through H and K' broad-band filters with the camera NICS. The image scale is 0.25arcsec/pixel, yielding a field of view of about 4.2'x4.2'. Observing strategy and exposure times are described in Deharveng et al. (2006A&A...458..191D), the only difference being that the dithering sequence for the H-band images was the same as adopted for K'. The data reduction steps adopted are outlined in Deharveng et al. (2006A&A...458..191D). Aperture photometry was done using the DAOPHOT package in IRAF. We followed the same procedure described in Deharveng et al. (2006A&A...458..191D) to obtain aperture photometry, after which PSF-fitting photometry was performed. Although the seeing was good (<1"), the night was barely photometric, so we calibrated our H, K' photometry with that performed on the same field by Deharveng et al. (2003, Cat. J/A+A/399/1135). We calculated the difference in magnitudes for each coinciding source and plotted it against our derived instrumental H-K'. A colour term was present in K' because of the difference between the K and K' filters. After a best-fit calibration, a residual r.m.s. of about 0.2mag. was present in the difference between our photometry and that of Deharveng et al. (2003, J/A+A/399/1135), probably because of the different seeing and possibly also due to the intrinsic variability of young stars. Our photometry is thus on the same HK standard system as Deharveng et al. (2003, J/A+A/399/1135). Sources with K, H < 11-12 are in the non-linear regime or saturated, but such bright objects are few in number and lie outside the cluster, and are probably foreground stars.

    Our sample of giants was chosen from Famaey et al. (2005, Cat. J/A+A/430/165). Spectra of 58 giants in the Hercules stream were obtained using the Robert G. Tull coude spectrograph at the Harlan J. Smith Telescope. Observed spectra cover the wavelength range 3800-10000Å. However, beyond ~5800Å, coverage is incomplete because of gaps between the recorded portions of the spectral orders, which progressively increase towards redder wavelengths. (9 data files).

    2015-07-15

    It is widely recognized that farmers' hold important knowledge of folk soil classification for agricultural land for its uses, yet little has been studied for traditional agroforestry systems. This article explores the ethnopedology of bamboo (Bambusa sp.) based agroforestry system in North East India, and establishes the relationship of soil quality index (SQI) with bamboo productivity. The study revealed four basic folk soil (mati) types: kalo (black soil), lal (red soil), pathal (stony soil) and balu (sandy soil). Of these, lal mati soil was the most predominant soil type (~ 40%) in bamboo-based agroforestry system. Soil physio-chemical parameters were studied to validate the farmers' soil hierarchal classification and also to correlate with productivity of the bamboo stand. Farmers' hierarchal folk soil classification was consistent with the laboratory scientific analysis. Culm production (i.e. measure of productivity of bamboo) was the highest (27culmsclump(-1)) in kalo mati (black soil) and the lowest (19culmsclump(-1)) in balu mati (sandy soil). Linear correlation of individual soil quality parameter with bamboo productivity explained 16 to 49% of the variability. A multiple correlation of the best fitted linear soil quality parameter (soil organic carbon or SOC, water holding capacity or WHC, total nitrogen) with productivity improved explanatory power to 53%. Development of SQI from ten relevant soil quality parameters and its correlation with bamboo productivity explained the 64% of the variation and therefore, suggest SQI as the best determinant of bamboo yield. Data presented indicate that the kalo mati (black soil) is sustainable or sustainable with high input. However, the other three folk soil types (red, stony and sandy soil) are also sustainable but for other land uses. Therefore, ethnopedological studies may move beyond routine laboratory analysis and incorporate SQI for assessing the sustainability of land uses managed by the farmers'. Additional

We searched the literature for all existing CO data for this Zucker et al. (2016, Cat. J/ApJ/821/113) subsample (294 galaxies) and obtained CO measurements for 102 HCG galaxies (Verdes-Montenegro et al., 1998ApJ...497...89V; Leon et al., 1998A&A...330...37L; Martinez-Badenes et al., 2012, Cat.

The observations were carried out with the Institut de Radioastronomie Millimetrique (IRAM) 30m telescope, Five College Radio Telescope, Swedish-ESO Submillimetre Telescope (SEST), and Kitt Peak Radio Telescope with single pointings at the central position for most cases. To supplement the CO data for these 104 galaxies from the literature, as part of this study we observed the redshifted CO(1-0) line for an additional 27 galaxies. We observed an additional 27 galaxies in CGs between January and April 2017 with the IRAM 30m telescope on Pico Veleta. We selected the sources, based on their WISE colors, as preferentially canyon or IRTZ objects. (1 data file).

    We selected the sample using radio catalogues to get the widest possible sample of blazars based on their radio properties. We split them into Fermi-detected sources and non-Fermi detections. Massaro et al. (2009, J/A+A/495/691) created the "Multifrequency Catalogue of Blazars" (Roma-BZCAT), which classifies blazars into three main groups based on their spectral properties. In total, we have a sample containing 177 clean Fermi blazars (96 Fermi FSRQs and 81 Fermi BL Lacs) and 133 non-Fermi blazars (105 non-Fermi FSRQs and 28 non-Fermi BL Lacs). (2 data files).

    Our study utilizes the public data and catalogs from multi-band deep surveys of the COSMOS field. The UltraVISTA survey (McCracken+ 2012, J/A+A/544/A156) provides ultra-deep near-IR imaging observations of this field in the Y,J,H, and Ks-band, as well as a narrow band (NB118). The HST/ACS I-band imaging data are publicly available, allowing us to measure morphologies in the rest-frame optical for galaxies at z<=1. The HST/ACS I-band images reach a 5σ depth of 27.2 magnitude for point sources. (1 data file).

  9. Pleiotropic effects of methionine adenosyltransferases deregulation as determinants of liver cancer progression and prognosis.

    PubMed

    Frau, Maddalena; Feo, Francesco; Pascale, Rosa M

    2013-10-01

    Downregulation of liver-specific MAT1A gene, encoding S-adenosylmethionine (SAM) synthesizing isozymes MATI/III, and upregulation of widely expressed MAT2A, encoding MATII isozyme, known as MAT1A:MAT2A switch, occurs in hepatocellular carcinoma (HCC). Being inhibited by its reaction product, MATII isoform upregulation cannot compensate for MATI/III decrease. Therefore, MAT1A:MAT2A switch contributes to decrease in SAM level in rodent and human hepatocarcinogenesis. SAM administration to carcinogen-treated rats prevents hepatocarcinogenesis, whereas MAT1A-KO mice, characterized by chronic SAM deficiency, exhibit macrovesicular steatosis, mononuclear cell infiltration in periportal areas, and HCC development. This review focuses upon the pleiotropic changes, induced by MAT1A/MAT2A switch, associated with HCC development. Epigenetic control of MATs expression occurs at transcriptional and post-transcriptional levels. In HCC cells, MAT1A/MAT2A switch is associated with global DNA hypomethylation, decrease in DNA repair, genomic instability, and signaling deregulation including c-MYC overexpression, rise in polyamine synthesis, upregulation of RAS/ERK, IKK/NF-kB, PI3K/AKT, and LKB1/AMPK axis. Furthermore, decrease in MAT1A expression and SAM levels results in increased HCC cell proliferation, cell survival, and microvascularization. All of these changes are reversed by SAM treatment in vivo or forced MAT1A overexpression or MAT2A inhibition in cultured HCC cells. In human HCC, MAT1A:MAT2A and MATI/III:MATII ratios correlate negatively with cell proliferation and genomic instability, and positively with apoptosis and global DNA methylation. This suggests that SAM decrease and MATs deregulation represent potential therapeutic targets for HCC. Finally, MATI/III:MATII ratio strongly predicts patients' survival length suggesting that MAT1A:MAT2A expression ratio is a putative prognostic marker for human HCC.

  10. Temporal Drivers of Liking Based on Functional Data Analysis and Non-Additive Models for Multi-Attribute Time-Intensity Data of Fruit Chews.

    PubMed

    Kuesten, Carla; Bi, Jian

    2018-06-03

    Conventional drivers of liking analysis was extended with a time dimension into temporal drivers of liking (TDOL) based on functional data analysis methodology and non-additive models for multiple-attribute time-intensity (MATI) data. The non-additive models, which consider both direct effects and interaction effects of attributes to consumer overall liking, include Choquet integral and fuzzy measure in the multi-criteria decision-making, and linear regression based on variance decomposition. Dynamics of TDOL, i.e., the derivatives of the relative importance functional curves were also explored. Well-established R packages 'fda', 'kappalab' and 'relaimpo' were used in the paper for developing TDOL. Applied use of these methods shows that the relative importance of MATI curves offers insights for understanding the temporal aspects of consumer liking for fruit chews.

    We have conducted simulations of the perturbation of the Oort cloud in order to estimate the significance of known encounters in generating long-period comets. We collected the data of stellar encounters from three sources: (Bailer-Jones, 2015, Cat. J/A+A/575/A35, hereafter BJ15), Dybczynski & Berski (2015MNRAS.449.2459D), and Mamajek et al. (2015ApJ...800L..17M). Following BJ15, we use the term 'object' to refer to each encountering star in our catalogue. A specific star may appear more than once but with different data, thus leading to a different object. (1 data file).

An initial sample of 5613 hot subdwarfs (Geier+ 2017, J/A+A/600/A50), which represents a good approximation of all cataloged hot subdwarf stars, was down-selected based on magnitudes, coordinates, and total exposure time available in the gPhoton database, described fully in Section 2. These selection criteria yielded 1881 targets upon which we focused our investigation. Calibrated light curves with time bins of 30s were generated for each target using gPhoton. (4 data files).

    Visibility data taken from LOTSS, imaged in polarization, and had RM synthesis applied. Resulting RM spectra were searched for polarization peaks. Detected peaks that were determined to not be foreground or instrumental effects were collected in this catalog. Source locations (for peak searches) were selected from TGSS-ADR1 (J/A+A/598/A78). Due to overlap between fields, some sources were detected multiple times, as recorded in the Ndet column. Polarized sources were cross-matched with the high-resolution LOTSS images (Shimwell+, in prep), and WISE and PanSTARRS images, which were used to determine the source classification and morphology.

    Until now, it has been impossible to observationally measure how star cluster scaleheight evolves beyond 1Gyr as only small samples have been available. Here, we establish a novel method to determine the scaleheight of a cluster sample using modelled distributions and Kolmogorov-Smirnov tests. This allows us to determine the scaleheight with a 25% accuracy for samples of 38 clusters or more. We apply our method to investigate the temporal evolution of cluster scaleheight, using homogeneously selected sub-samples of Kharchenko et al. (MWSC, 2012, Cat. J/A+A/543/A156, 2013, J/A+A/558/A53 ), Dias et al. (DAML02, 2002A&A...389..871D, Cat. B/ocl), WEBDA, and Froebrich et al. (FSR, 2007MNRAS.374..399F, Cat. J/MNRAS/374/399). We identify a linear relationship between scaleheight and log(age/yr) of clusters, considerably different from field stars. The scaleheight increases from about 40pc at 1Myr to 75pc at 1Gyr, most likely due to internal evolution and external scattering events. After 1Gyr, there is a marked change of the behaviour, with the scaleheight linearly increasing with log(age/yr) to about 550pc at 3.5Gyr. The most likely interpretation is that the surviving clusters are only observable because they have been scattered away from the mid-plane in their past. A detailed understanding of this observational evidence can only be achieved with numerical simulations of the evolution of cluster samples in the Galactic disc. Furthermore, we find a weak trend of an age-independent increase in scaleheight with Galactocentric distance. There are no significant temporal or spatial variations of the cluster distribution zero-point. We determine the Sun's vertical displacement from the Galactic plane as Z⊙=18.5+/-1.2pc.

    Table 1 contains the best-fitting values of size and beaming parameter and corresponding visible geometric albedos for the full AKARI IRC sample. We fitted the near-Earth asteroid thermal model (NEATM) of Harris (1998Icar..131..291H) to the AKARI IRC thermal infrared data (Murakami et al., 2007PASJ...59S.369M, Onaka et al., 2007PASJ...59S.401O, Ishihara et al., 2010A&A...514A...1I, Cat.

The NEATM implementation is described in Ali-Lagoa and Delbo' (2017A&A...603A..55A, cat. J/A+A/603/A55). Minimum relative errors of 10, 15, and 20 percent are given for size, beaming parameter and albedo in those cases where the beaming parameter could be fitted. Otherwise, a default value of the beaming parameter is assumed based on Eq. 1 in the article, and the minimum relative errors in size and albedo increase to 20 and 40 percent (see the discussions in Mainzer et al., 2011ApJ...736..100M, Ali-Lagoa et al., 2016A&A...591A..14A, Cat.

    2017-06-01

    Cerium oxides are widely used in heterogeneous catalysis due to their ability to switch between different oxidation states. We report here the mass-analyzed threshold ionization (MATI) spectroscopy of cerium monoxide (CeO) produced by laser ablating a Ce rod in a molecular beam source. The MATI spectrum in the range of 40000-45000 \\wn exhibits several band systems with similar vibrational progressions. The strongest band is at 43015 (5) \\wn, which can be assigned as the adiabatic ionization energy of the neutral species. The spectrum also shows Ce-O stretching frequencies of 817 and 890 \\wn in the neutral and ion states, respectively. By comparing with spin-orbit coupled multireference quasi-degenerate perturbation theory (SO-MCQDPT) calculations, the observed band systems are assigned to transitions from various low-energy spin-orbit levels of the neutral oxide to the two lowest spin-orbit levels of the corresponding ion. The current work will also be compared with previous experimental and computational studies on the neutral species.

  9. An investigation of electronic states of some molecules and molecular cations using mass analyzed threshold ionization and photoinduced Rydberg ionization spectroscopy

    NASA Astrophysics Data System (ADS)

    Hofstein, Jason David

    1999-11-01

    Mass analyzed threshold ionization (MATI) experiments have enabled mapping of the n-dependent Rydberg state survival probability for a series of molecules. Utilizing vacuum and extreme ultraviolet (VUV/XUV) photons, one photon Rydberg manifold spectra of argon, hydrogen chloride, nitrogen, benzene, and oxygen were produced, and the prospects of photoinduced Rydberg ionization (PIRI) experiments examined. It was found that the widths of Rydberg manifolds for the molecules studied are quite different. Hydrogen chloride and nitrogen have the narrowest manifold width, followed by benzene, and then oxygen. These varying widths are most strongly correlated with the angular momentum (i.e., quantum defect) of the initially prepared Rydberg orbital. PIRI experiments required the use of a static cell, rather than a molecular jet assembly, for the more efficient production of higher amounts of VUV/XUV radiation, and hence more Rydberg signal needed to observe PIRI. Armed with the ability to produce tunable VUV/XUV radiation, and to determine the feasibility of a PIRI experiment, the MATI and fragment PIRI spectra of trans-1,3-butadiene (BD) were recorded. The MATI spectrum is vibrationally resolved and was analyzed with the help of ab initio calculations and other published results. The fragment PIRI spectrum of the A<==X transition of BD+ is not vibrationally resolved, but information regarding the wavelength dependence of fragmentation pathways has been gathered and interpreted. It was found that at low photodissociation photon energies, production of C3H3+ dominates, but at higher photon energies, C2H4 + is also produced. The production of each fragment showed a definite PIRI wavelength dependence.

    2005-08-22

    The first results are presented of a new experiment designed both to generate and characterize spectroscopically individual isomers of transition-metal cluster cations. As a proof of concept the one-photon mass-analyzed threshold ionization (MATI) spectrum of V3 has been recorded in the region of 44,000-45,000 cm-1. This study extends the range of a previous zero-kinetic-energy (ZEKE) photoelectron study of Yang et al. [Chem. Phys. Lett. 231, 177 (1994)] with which the current results are compared. The MATI spectra reported here exhibit surprisingly high resolution (0.2 cm-1) for this technique despite the use of large discrimination and extraction fields. Analysis of the rotational profile of the origin band allows assignment of the V3 ground state as and the V3+ ground state as , both with D3h geometry, in agreement with the density-functional theory study of the V3 ZEKE spectrum by Calaminici et al. [J. Chem. Phys. 114, 4036 (2001)]. There is also some evidence in the spectrum of transitions to the low-lying excited state of the ion. The vibrational structure observed in the MATI spectrum is, however, significantly different to and less extensive than that predicted in the density-functional theory study. Possible reasons for the discrepancies are discussed and an alternative assignment is proposed which results in revised values for the vibrational wave numbers of both the neutral and ionic states. These studies demonstrate the efficient generation of cluster ions in known structural (isomeric) forms and pave the way for the study of cluster reactivity as a function of geometrical structure.

    We present near-infrared H-band (1.65μm) surface photometry of 297 galaxies (mostly) in the Coma Supercluster obtained with the Arcetri NICMOS3 camera, ARNICA, mounted on the Gornergrat Infrared Telescope. Magnitudes and diameters within the 21.5mag/arcsec2 isophote, concentration indices, and total H magnitudes are derived. Combining these observations with those obtained similarly using the Calar Alto telescopes (Paper I, <J/A+AS/120/489>) we find a strong positive correlation between the near-infrared concentration index and the galaxy H-band luminosity, and we analyze the consequent dependence of near-infrared growth-curves on H-band luminosity. For a description of the H band photometric system, see e.g. (2 data files).

    A catalogue is presented of galaxies having large-scale observations in the HI line. This catalogue collects from the literature the information that characterizes the observations in the 21-cm line and the way that these data were presented by means of maps, graphics and tables, for showing the distribution and kinematics of the gas. It contains furthermore a measure of the HI extension that is detected at the level of the maximum sensitivity reached in the observations. This catalogue is intended as a guide for references on the HI maps published in the literature from 1953 to 1995 and is the basis for the analysis of the data presented in Paper II (Cat. <J/A+AS/131/77>).

    Introduction Ce travail vise à faire une évaluation des nuisances dans le milieu de travail du secteur textile en République Démocratique du Congo. Méthodes Nous avons effectué une étude transversale et analytique. Sur 257 travailleurs sélectionnés par échantillonnage systématique, 229 travailleurs ont été retenus. 223 postes de travail ont fait l'objet de mesures pour le bruit, l'éclairage, et la chaleur. Les informations recueillies l'ont été à partir de la consultation des documents de l'entreprise, de l'interrogatoire mené par questionnaire dirigé portant essentiellement sur les renseignements socio professionnels et par des mesurages. L'analyse descriptive a été faite pour les données sociodémographiques et professionnelles et l'approche analytique pour les mesurages. Résultats Dans cette entreprise 88% des travailleurs sont des ouvriers. Le département de tissage englobe presque 68% des travailleurs. La plupart travaillent en trois pauses (85%). La population d'étude est majoritairement masculine à 85%, vieillissante avec 52% de plus de 40 ans et instruite (80%). Dans l'entreprise, seuls 12,1 % des postes de travail respectent les normes en matière de bruit et 18 % des postes en matière d'éclairage. 94% des postes ne respectent pas les normes en matière de chaleur pour un travail lourd. Conclusion Notre étude a permis de mettre en évidence les nuisances au sein de l'industrie, montrant un écart important par rapport aux normes prescrites pour les nuisances mesurées. Ces résultats est un plaidoyer pour développer des mesures de prévention appropriées. Ils sont à confronter à ceux d'autres études plus approfondies dans ce milieu. PMID:28154733

    2018-05-01

    La atom reaction with isoprene is carried out in a laser-vaporization molecular beam source. The reaction yields an adduct as the major product and C—C cleaved and dehydrogenated species as the minor ones. La(C5H8), La(C2H2), and La(C3H4) are characterized with mass-analyzed threshold ionization (MATI) spectroscopy and quantum chemical computations. The MATI spectra of all three species exhibit a strong origin band and several weak vibronic bands corresponding to La-ligand stretch and ligand-based bend excitations. La(C5H8) is a five-membered metallacycle, whereas La(C2H2) and La(C3H4) are three-membered rings. All three metallacycles prefer a doublet ground state with a La 6s1-based valence electron configuration and a singlet ion. The five-membered metallacycle is formed through La addition and isoprene isomerization, whereas the two three-membered rings are produced by La addition and insertion, hydrogen migration, and carbon-carbon bond cleavage.

    Le prémélange de monensin est utilisé fréquemment sur les fermes laitières canadiennes. L’ingrédient actif de ce produit est le monensin sodique. Bien que son utilisation chez les vaches laitières soit sécuritaire, des cas de surdose ont été rapportés à la suite de consommation de niveaux de monensin plus élevés que ceux recommandés. Un suivi hebdomadaire du pourcentage de matières grasses du réservoir de lait de la ferme devrait être fait de routine suite à la livraison d’aliment médicamenteux contenant du monensin pour détecter rapidement les situations de surdose. L’observation d’une baisse soudaine de la consommation volontaire de matière sèche et l’apparition de diarrhée dans un troupeau sont d’autres signes cliniques de surdose de monensin. Une détection rapide de ces cas permettra de corriger la situation. PMID:19721781

    High-resolution spectroscopic observations for 35 candidates from the surveys of Slesnick+ (2006, J/AJ/132/2665) and Li & Hu (1998, J/A+AS/132/173) were previously obtained with Keck/HIRES on 2006 December 12 and 13 (PIs Carpenter and Slesnick). We downloaded these observations, extracted the spectra, and analyzed them to measure the radial velocity, Hα equivalent width, and Li equivalent width for each object. We observed 32 candidates with the SuperNova Integral Field Spectrograph (SNIFS) on the University of Hawaii 2.2m telescope between 2014 November and 2015 January (PIs Herczeg and Mann). These observations (R~1000) are similar to those described by Mann+ (2015, J/ApJ/804/64), who describe some of the observations and reductions in more detail. See section 3 for further details.

    The 2XMMi-DR2 catalog (Cat. IX/40) consists of observations made with the XMM-Newton satellite between 2000 and 2008 and covers a sky area of about 420 deg2. The observations were made using the European Photon Imaging Camera (EPIC) that consists of three CCD cameras - pn, MOS1, and MOS2 - and covers the energy range from 0.2 keV to 12 keV. There are 221012 unique sources in 2XMM-DR2, of which 2267 were flagged as variable by the XMM processing pipeline (Watson et al. 2009, J/A+A/493/339). The variability test used by the pipeline is a {Chi}2 test against the null hypothesis that the source flux is constant, with the probability threshold set at 10-5. (1 data file).

    We modeled the HARPS radial velocities of HD 42148 by adopting the analysis techniques and the statistical model applied in Tuomi et al. (2014, arXiv:1405.2016). This model contains Keplerian signals, a linear trend, a moving average component with exponential smoothing, and linear correlations with activity indices, namely, BIS, FWHM, and chromospheric activity S index. We applied our statistical model outlined above to the full data set of radial velocities for HD 41248, combining the previously published data in Jenkins et al. (2013ApJ...771...41J) with the newly published data in Santos et al. (2014, J/A+A/566/A35), giving rise to a total time series of 223 HARPS (Mayor et al. 2003Msngr.114...20M) velocities.

    2011-01-01

    Le Cameroun utilise un système de budgétisation historique et une approche «top-down» pour allouer ses ressources de santé publique. Cependant, le pays compte 175 districts de santé dont les fortes disparités de nature épidémiologique, économique, géographique et culturelle, devraient être prises en compte pour réduire les iniquités en matière de sante publique. Comment comprendre alors que dans ces conditions, le budget des administrations publiques alloué aux différents districts de santé au Cameroun soit quasi identique alors que les défis sont si différents? L'inefficience allocative (mauvaise attribution du budget) générée par un tel système conduit vraisemblablement à une inefficience technique (mauvaise utilisation du budget). Pour la marche vers l'atteinte des objectifs du millénaire en matière de sante, il est impératif et urgent que les décideurs du secteur de la santé allouent de manière intelligente les ressources dans le système de santé.

    High-resolution mass-analyzed threshold ionization (MATI) spectra of (η 6 -Ph 2 ) 2 Cr and (η 6 -Ph 2 )(η 6 -PhMe)Cr demonstrate that the Ph groups work as electron donors, decreasing the ionization energy of the gas-phase bisarene complexes. In contrast to electrochemical data, a close similarity of the Ph and Me group effects on the oxidation of free sandwich molecules has been revealed. However, DFT calculations testify for the opposite shifts of the electron density caused by the Me and Ph substituents in the neutral complexes, the latter behaving as an electron-accepting fragment. On the contrary, in the bisarene cations, the Ph group becomes a stronger donor than methyl. This change provides the similar substituent effects observed with the MATI experiment. On the other hand, the well-documented opposite influence of the Me and Ph fragments on the redox potential of the (η 6 -arene) 2 Cr +/0 couple in solution appears to be a result of solvation effects but not intramolecular interactions as shown for the first time in this work. © 2017 Wiley-VCH Verlag GmbH & Co.

  6. Lanthanum-mediated dehydrogenation of butenes: Spectroscopy and formation of La(C4H6) isomers

    NASA Astrophysics Data System (ADS)

    Cao, Wenjin; Hewage, Dilrukshi; Yang, Dong-Sheng

    2018-01-01

    La atom reactions with 1-butene, 2-butene, and isobutene are carried out in a laser-vaporization molecular beam source. The three reactions yield the same La-hydrocarbon products from the dehydrogenation and carbon-carbon bond cleavage and coupling of the butenes. The dehydrogenated species La(C4H6) is the major product, which is characterized with mass-analyzed threshold ionization (MATI) spectroscopy and quantum chemical computations. The MATI spectrum of La(C4H6) produced from the La+1-butene reaction exhibits two band systems, whereas the MATI spectra produced from the La+2-butene and isobutene reactions display only a single band system. Each of these spectra shows a strong origin band and several vibrational progressions. The two band systems from the spectrum of the 1-butene reaction are assigned to the ionization of two isomers: La[C(CH2)3] (Iso A) and La(CH2CHCHCH2) (Iso B), and the single band system from the spectra of the 2-butene and isobutene reactions is attributed to Iso B and Iso A, respectively. The ground electronic states are 2A1 (C3v) for Iso A and 2A' (Cs) for Iso B. The ionization of the doublet state of each isomer removes a La 6s-based electron and leads to the 1A1 ion of Iso A and the 1A' ion of Iso B. The formation of both isomers consists of La addition to the C=C double bond, La insertion into two C(sp3)—H bonds, and H2 elimination. In addition to these steps, the formation of Iso A from the La+1-butene reaction may involve the isomerization of 1-butene to isobutene prior to the C—H bond activation, whereas the formation of Iso B from the La+trans-2-butene reaction may include the trans- to cis-butene isomerization after the C—H bond activation.

    The presented tables summarize the parameters for the clusters and the mean values for the detected potential cluster groupings. The ages, distances and proper motions were taken from the Catalogue of Open Cluster Data (COCD; Kharchenko et al. 2005, Cat. J/A+A/438/1163, J/A+A/440/403), while additional radial velocities and metallicities were obtained from the Radial Velocity Experiment (RAVE; Kordopatis et al. 2013AJ....146..134K, Cat. III/272 ) and from the online compilation provided by Dias et al. (2002, See B/ocl). A description of the determination for the radial velocities and metallicities can be found in Conrad et al. 2014A&A...562A..54C. The potential groupings were identified using an adapted Friends-of-Friends algorithm with two sets of linking lengths, namely (100pc, 10km/s) and (100pc, 20km/s). The table clupar.dat (combining Tables A.1 and A.2 from the Appendix of our paper): Tables comprises the parameters collected for the final working sample of 432 clusters with available radial velocities, namely coordinates and proper motions in equatorial and galactic coordinates, distances, ages, metallicities, as well as Cartesian coordinates and velocities. The latter were computed through converting the spherical parameters to Cartesian space with the sun as point of origin. The tables grpar10.dat and grpar20.dat (listed as two parts in Table B.1 of the Appendix of our paper) contain the mean values for the identified potential open cluster groupings for two sets of linking lengths, 100pc and 10km/s (19 potential groupings) and 100pc and 20km/s (41 potential groupings), respectively. These were computed as simple mean, while the uncertainties were computed as simple rms. We list the counting number, the number of members, the COCD number and name for each member, The mean Cartesian coordinates and velocities, along with the uncertainties, the mean distances (with uncertainties), the mean logarithmic ages (with uncertainties) and the mean metallicities

    Currently, antimicrobial peptides have attracted considerable attention because of their broad-sprectum activity and low prognostic to induce antibiotic resistance. In our study, for the first time, a series of side-chain hybrid dimer peptides J-AA (Anoplin-Anoplin), J-RR (RW-RW), and J-AR (Anoplin-RW) based on the wasp peptide Anoplin and the arginine- and tryptophan-rich hexapeptide RW were designed and synthesized by click chemistry, with the intent to improve the antimicrobial efficacy of peptides against bacterial pathogens. The results showed that all dimer analogues exhibited up to a 4-16 fold increase in antimicrobial activity compared to the parental peptides against bacterial strains. Furthermore, the antimicrobial activity was confirmed by time-killing kinetics assay with two strains which showed that these dimer analogues at 1, 2×MIC were rapidly bactericidal and reduced the initial inoculum significantly during the first 2-6h. Notably, dimer peptides showed synergy and additivity effects when used in combination with conventional antibiotics rifampin or penicillin respectively against the multidrug-resistant strains. In the Escherichia coli-infected mouse model, all of hybrid dimer analogues had significantly lower degree of bacterial load than the untreated control group when injected once i.p. at 5mg/kg. In addition, the infected mice by methicillin-resistant (MRSA) strain could be effectively treated with J-RR. All of dimer analogues had membrane-active action mode. And the membrane-dependent mode of action signifies that peptides functions freely and without regard to conventional resistant mechanisms. Circular dichroism analyses of all dimer analogues showed a general predominance of α-helix conformation in 50% trifluoroethanol (TFE). Additionally, the acute toxicities study indicated that J-RR or J-AR did not show the signs of toxicity when adult mice exposed to concentration up to 120mg/kg. The 50% lethal dose (LD 50 ) of J-AA was 53.6mg

    We reported the list of hard X-ray blazars obtained adopting sigma=3 as detection threshold: with this choice a number of three spurious sources over a total of 121 blazars is expected. Each blazar is identified by a three-letter code, where the first two are BZ for blazar and the third one specifies the type, followed by the truncated equatorial coordinates (J2000). The codes are defined in the "Note (1)" below. We obtained 69 FSRQs, 24 BL Lac objects and 28 blazars of uncertain classification, representing 4.4%, 2.4% and 11.0% of the corresponding populations classified in the BZCAT, respectively. This sample has been compared with other lists and catalogues found in literature (Tueller et al., 2010, Cat. J/ApJS/186/378, Ajello et al. 2009ApJ...699..603A, Cusumano et al., 2010, Cat.

    Being a dynamic environment associated with complex costal, fluvial and marine processes, only a few studies regarding the evolution of the Danube Delta and the human impacts on its ecosystem have been carried out. Being a sensible to all processes occurring in its catchment area, information is stored in the deposited sediments, which can be used as tracers for natural and anthropogenic processes. The aim of this study is to determine a detailed reconstruction of the sedimentation rates in the last century by applying the 210 Pb dating method validated by 137 Cs profiles. Additionally, the impacts of the construction of river-regulating structures (mainly the Iron Gates Hydro-Energetic Power Plants) are investigated, along with the assessment of natural phenomena (floods, storms etc.). To achieve this, 26 sediment cores from seven lakes were collected. 210 Pb sup and 137 Cs were determined using gamma spectrometry, while 210 Pb tot was measured via alpha spectrometry ( 210 Po), using the CRS model for age determination. From the assessed lakes, the most affected was the Matița Lake with a maximum sedimentation rate of 10.93 g cm -2 yr -1 and the least affected was the Isac Lake. Average sedimentation rates are: 0.95 g cm -2 yr -1 for Cruhlig Lake, 0.70 g cm -2 yr -1 for Uzlina Lake, 0.44 g cm -2 yr -1 for Isac Lake, 0.47 g cm -2 yr -1 for Cuibida Lake, 0.51 g cm -2 yr -1 for Iacob Lake, 1.00 g cm -2 yr -1 for Matița Lake and 0.76 g cm -2 yr -1 for Merhei Lake. Physical parameters (water content, porosity and bulk density) and LOI (organic matter and inorganic carbon content) were determined for each core to differentiate organic and non-organic sedimentation. Beside the natural influences, it is difficult to track the effects of the Iron Gates and not all analysed lakes were suitable for this task. The 1940-1970 period and the following ten years were compared in means of sedimentation: a decrease in sedimentation can be observed

    Résumé Objectif Fournir aux médecins de première ligne une approche relative aux préoccupations de sécurité au volant lorsque les personnes âgées présentent des troubles de mémoire. Sources d’information L’approche est fondée sur un programme de formation agréé des cliniques de la mémoire, élaboré par la clinique de la mémoire du Centre for Family Medicine. Message principal L’un des aspects les plus difficiles des soins aux personnes atteintes de démence est l’évaluation de la sécurité au volant. Les conducteurs atteints de démence présentent un risque plus élevé de collisions, quoique de nombreux conducteurs dont l’atteinte est légère soient aptes à conduire pendant encore plusieurs années. Puisque l’aptitude à conduire dépend de multiples compétences cognitives et fonctionnelles, de nombreux facteurs entrent en jeu lorsque les cliniciens déterminent si les sujets de préoccupation en matière de cognition se répercutent sur l’aptitude à conduire. Les observations spécifiques tirées de l’anamnèse corroborée et des tests cognitifs effectués en cabinet pourraient aider le médecin à décider s’il doit recommander le patient à un examen pratique complet et aviser les autorités provinciales du transport, conformément aux exigences en matière de déclarations. La communication doit être axée sur le patient et menée avec tact. Conclusion Les médecins de première ligne doivent tenir compte de plusieurs facteurs lorsqu’ils déterminent si les sujets de leurs préoccupations en matière de cognition pourraient se répercuter sur l’aptitude des conducteurs âgés à prendre le volant.

    Kraus & Hillenbrand (2007, J/AJ/134/2340) calculated proper motions and photometry for several million objects within 7° of the center of Praesepe. The resulting catalog includes 1128 candidate cluster members with membership probabilities Pmem>50%. As in Paper I (Agueros et al. 2011ApJ...740..110A), we supplement this catalog with 41 known members that are too bright to be identified as members by Kraus & Hillenbrand (2007, J/AJ/134/2340). For the Hyades, we adopt the Roser et al. (2011, J/A+A/531/A92) membership catalog. These authors identified candidate Hyades members via the convergent point method and confirmed membership using photometry. We used the MDM Observatory Modular Spectrograph (ModSpec) on the Hiltner 2.4 m telescope to obtain spectra of stars in Praesepe and the Hyades over the course of five multi-night runs between 2010 December 2 and 2012 November 14.

    We start with the total sample from the AGN MIR atlas of 253 objects (Asmus et al. 2014, J/MNRAS/439/1648). Note that sample is a combination of a hard X-ray (14-195 keV) selected and a quasi-MIR selected sample as explained in Asmus et al. (2014, J/MNRAS/439/1648). The MIR continuum fluxes are the unresolved nuclear fluxes extracted from ground-based multifilter photometry obtained with the instruments VISIR (Lagage et al. 2004Msngr.117...12L), T-ReCS (Telesco et al. 1998SPIE.3354..534T), Michelle (Glasse, Atad-Ettedgui & Harris 1997SPIE.2871.1197G), and COMICS; (Kataza et al. 2000SPIE.4008.1144K). We collect observed 14-195 keV fluxes, Fobs(14-195 keV), measured with Swift/BAT (Burst Alert Telescope) by combining the data of the 54 and 70 month source catalogues with preference for the latter (Cusumano et al. 2010, J/A+A/524/A64; Baumgartner et al. 2013, J/ApJS/207/19).

    All of the 12 selected molecular clouds have GLIMPSE and MIPSGAL public data available. Typical Spitzer RGB images (3.6um, 8.0um, and 24um) of the resulting sample of clouds are shown in Figure 1, where the position of the IRAS source is identified. In order to define the parent molecular cloud that harbors the high-mass star-forming regions, we used 13CO(J=1-0) emission data from the Galactic Ring Survey (GRS) database (Jackson+ 2006ApJS..163..145J). The survey data have a velocity resolution of 0.21km/s, a typical (1σ) rms sensitivity of ~0.13K, a main beam efficiency of {eta}mb=0.48, and a beam of 46". The 13CO emission spectra for the line of sight (LOS) to the selected IRAS sources are shown in Figure 2, where the observed velocity of the CS(J=2-1) emission line (Bronfman+ 1996, J/A+AS/115/81) is also marked.

    Spectroscopic observations of KELT-14 and KELT-15 were carried out using the CYCLOPS2 fiber feed with the UCLES spectrograph instrument on the Anglo-Australian Telescope (AAT) over two observing runs: UT 2015 February 02-UT 2015 March 01 and UT 2015 May 6-UT 2015 May 13. The instrumental set-up and observing strategy for these observations closely follow that described in earlier CYCLOPS RV papers (Addison et al. 2013ApJ...774L...9A, 2014ApJ...792..112A). CORALIE is a fiber-fed echelle spectrograph (Queloz et al. 2001Msngr.105....1Q) attached to the Swiss 1.2 m Leonard Euler telescope at the ESO La Silla Observatory in Chile. It has a spectral resolution of R~60000, a wavelength range of 3900-6800 Å, and is able to measure radial velocities of bright stars to a precision of 3 m/s or better (Pepe et al. 2002, J/A+A/388/632). We obtained spectra at five epochs of KELT-15 from UT 2015 September 02 to UT 2015 September 14. (3 data files).

    2013-07-01

    The XMM-Newton survey of the Small Magellanic Cloud (SMC) yields a complete coverage of the bar and eastern wing in the 0.2-12.0keV band. This catalogue comprises 3053 unique X-ray point sources and sources with moderate extent that have been reduced from 5236 individual detections found in observations between April 2000 and April 2010. Sources have a median position uncertainty of 1.3" (1σ) and limiting fluxes down to ~1*10-14erg/s/cm2 in the 0.2-4.5keV band, corresponding to 5*1033erg/s for sources in the SMC. Sources have been classified using hardness ratios, X-ray variability, and their multi-wavelength properties. In addition to the main-field (5.58deg2) available outer fields have been included in the catalogue, yielding a total field area of 6.32deg2. X-ray sources with high extent (>40", e.g. supernova remnants and galaxy cluster) have been presented by Haberl et al. (2012, Cat. J/A+A/545/A128) (2 data files).

    Single-aperture mid-infrared images and spectra were taken with the VLT spectrometer and imager for the mid-infrared (VISIR). Interferometric measurements were obtained with the instrument MIDI at the ESO's VLTI facility. Observations with intermediate AT baselines were requested and observed during the nights of January, 10, 20, and 23, 2015 using Director's discretionary time (DDT). We additionally included published and unpublished interferometric data from our previous campaigns with the requirement that they were observed (nearly) contemporaneously to the period of X-ray variation or observed a few years before. These include observations taken on the nights of September, 21, 26, and 30, 2014, and November, 17, 2014, using Guaranteed Time Observations (GTO). For our observations we used the low-resolution NaCl prism with spectral resolution R=λ/Δλ~30 to disperse the light of the beams. A log of the observations and instrument setup can be found in Appendix A. The published data were taken from Lopez-Gonzaga et al. (2014A&A...565A..71L, Cat. J/A+A/565/A71). (2 data files).

    The details about synthesis and identification by NMR spectroscopy were described in Carvajal et al. (2009, Cat. J/A+A/500/1109). The millimeter- and submillimeter-wave spectra were recorded using the Lille spectrometer that is based on solid-state sources. The sample pressure was in the range 20-30x10-6 bars. Spectra were recorded at room temperature (T=294K) in the 150-210, 225-315, 400-500, 500-630, and 780-940GHz regions with frequency steps of 30, 36, 48, 54, and 76kHz and an acquisition time of 35ms per point. The absolute accuracy of the line-centre frequency is estimated to be better than 30kHz (50kHz above 700GHz) for isolated lines and can be as low as 100kHz (150kHz above 700GHz) for blended or very weak lines. See section 2.2. The IRAM spectra will be published on the IRAM website: http://www.iram-institute.org/ (1 data file).

    Shortly after the detection of 55 Cnc e's transit was announced, we requested four spectroscopic time series on HARPS (Prog. ID 288.C-5010; PI: Triaud) as Director Discretionary Time. HARPS is installed on the 3.6 m telescope at the European Southern Observatory on La Silla, Chile (Mayor et al. 2003Msngr.114...20M). The position of 55 Cnc in the sky-RA(J2000)=08:52:35.81, DE(J2000)=+28:10:50.95-is low as seen from La Silla. The target remains at a zenith distance of z<2 for only ~2.5 hr per night, with a transit duration of about 1.5 hr having to fit within this tight window. This constraint on the airmass, essential to obtain precise radial velocities (RVs), is set by the instrumental atmospheric dispersion corrector. We used the ephemeris by Gillon et al. (2012, J/A+A/539/A28), then at an advanced stage of preparation, to schedule our observations. In total, we gathered 179 spectra on the nights starting on 2012 January 27, 2012 February 13, 2012 February 27, and 2012 March 15 UT. (1 data file).

  6. LA-ICP-MS Pb-U Dating of Young Zircons from the Kos-Nisyros Volcanic Centre, SE Aegean Arc (Greece)

    2014-12-01

    Zircon Pb-U dating has become a key technique for answering many important questions in geosciences. This paper describes a new LA-ICP-MS approach. We show, using previously dated samples of a large quaternary rhyolitic eruption in the Kos-Nisyros volcanic centre (the 161 ka Kos Plateau Tuff), that the precision of our LA-ICP-MS method is as good as via SHRIMP, while ID-TIMS measurements confirm the accuracy. Gradational age distribution over >140 ka of the Kos zircons and the near-absence of inherited cores indicate near-continuous crystallisation in a growing magma reservoir with little input from wall rocks. Previously undated silicic eruptions from Nisyros volcano (Lower Pumice, Nikia Flow, Upper Pumice), which are stratigraphically constrained to have happened after the Kos Plateau Tuff, are dated to be younger than respectively 124 ± 35 ka, 111 ± 42 ka and 70 ± 24 ka. Samples younger than 1 Ma were corrected for initial thorium disequilibrium using a new formula that also accounts for disequilibrium in 230Th decay.

    2018-01-01

    The sample was originally presented by Gonzalez-Martin+ (2015, J/A+A/578/A74). The LINER sample is selected as those objects with reported X-ray luminosities from Gonzalez-Martin+ (2009A&A...506.1107G) with full coverage of the 5-30um range with the InfraRed Spectrograph (Spitzer/IRS) spectra. This guarantees that all of the LINERs have LX(2-10keV) measurements. Among the 48 LINERs with Spitzer/IRS spectra, 40 mid-infrared spectra were taken from the CASSIS atlas (Lebouteiller+ 2011ApJS..196....8L) and 8 from the SINGS database (Kennicutt+ 2003PASP..115..928K). We have included in our analysis mid-infrared spatially resolved images taken with CanariCam/GTC using the filter "Si6" centered at 11.5um. These observations are part of proprietary data of a sample of faint and Compton-thick LINERs observed with CanariCam/GTC (proposal ID GTC10-14A, P.I. Gonzalez-Martin). The summary of the observations used in this paper is reported in Table 4. See section 3.2 for further explanations. (5 data files).

    Tyler, K. D.; Bai, L.; Rieke, G. H.

    2017-04-01

    A2255 was initially chosen from the Popesso et al. (2007, J/A+A/461/397) sample because it is a large cluster with complete SDSS photometric and spectroscopic coverage out to ~3 r200. It has incomplete areal spectroscopic coverage from 3 r200<~rproj<~5 r200 - about half of this region is covered. The SDSS photometric survey provides a uniform data set to study galaxy properties in the cluster. The model magnitudes are the linear combinations of best-fit exponential and de Vaucouleurs profiles and are recommended as the best estimates of magnitude by SDSS. As such, we use the model magnitudes (except where explicitly stated otherwise) and correct them for Galactic extinction (O'Donnell, 1994ApJ...422..158O). We used these photometric data to estimate galactic stellar masses with the SDSS_KCORRECT routine within KCORRECT (v. 4.2; Blanton & Roweis 2007AJ....133..734B). KCORRECT uses different cosmological values and initial mass function, so we corrected the original stellar mass output to the cosmology and initial mass function (Kroupa, 2001MNRAS.322..231K) adopted in this paper.

    The aim of this study is to determine the effects of natural and anthropic events occurring in the last 30 years in the catchment areas of four Romanian lakes (St. Anna Lake, Red Lake, Vârşolţ Lake and Matiţa Lake) originating from four different geomorphologic areas. A total of eleven sediment cores have been processed for age and sedimentation rate determination using the 210 Pb dating method. Total 210 Pb was measured via alpha spectrometry by 210 Po using PIPS detectors, while supported 210 Pb was measured by 226 Ra using HPGe detectors. Ages and sedimentation rates were calculated using the CRS model. The values of the sedimentation rates have grown multiply in the last three decades: 2.66 times in case of the St. Anna Lake (from 0.06 ± 0.01 g/cm 2 y to 0.16 ± 0.02 g/cm 2 y), up to 6.72 times in case of Red Lake (0.36 ± 0.04 g/cm 2 y to 2.42 ± 0.36 g/cm 2 y), 4.02 times in case of Vârşolţ Lake (04 g/cm 2 y to 1.53 ± 0.18 g/cm 2 y) and up to 16.18 times in case of Matiţa Lake (0.27 ± 0.03 g/cm 2 y to 4.37 ± 0.32).

    Taherkhani, Mehran; Armentano, Antonio; Černý, Jiří; Müller-Dethlefs, Klaus

    2016-07-01

    Tryptophan (Trp) was studied by two-colour Photoionization Efficiency (PIE) and Mass Analysed Threshold Ionization (MATI) spectroscopy using a laser desorption apparatus. Conformer A of Trp was excited into the S1 state (34,878 cm-1) and the second laser was scanned around the D0 cation ground and the D1 excited state. No ionization signal into the D0 state could be found, but a clear threshold was observed for the D1 state with an ionization energy of 66,704 ± 3 cm-1 (8.27 eV). This observation is explained in terms of the electronic configurations of the S1 and cationic states.

    2005-05-01

    A cause de la sécheresse qui a sévit durant une décennie, la station de traitement de l'eau potable de la ville de Skikda Algérie, en vue de combler le déficit en eau, utilise un mélange des eaux de surface (barrage) et des eaux souterraines (forage). Les résultats des analyses physico-chimiques de ces eaux montrent la présence de micropolluants, notamment le mercure, avec une concentration de 0.035 mg/l pour les eaux de surface et une concentration de 0.02 mg/l pour les eaux souterraines. Ces résultats obtenus, montrent également que la concentration en matières organiques dépasse, pour les deux sources, les normes OMS. Afin de réduire les effets de cette pollution, nous avons calculé les doses nécessaires des différents réactifs utilisés sur la base des essais d'optimisation réalisés en laboratoire. Les résultats obtenus nous ont permis de conclure que les doses de 30 à 60 mg/l de sulfate d'aluminium (S.A) sont nécessaires à une bonne élimination de la turbidité et des matières organiques (M.O) et que l'utilisation du charbon active en poudre (C.A.P) permet la réduction de la teneur en mercure au dessous du seuil admissible. L'utilisation d'un adjuvant (chaux vive) permet d'améliorer les résultats surtout pour la turbidité (4 mg/l). Une préchloration au break point semble intéressante pour améliorer la phase de floculation.

    2012-06-01

    The interaction between methanol (CH_3OH) molecules and laser-vaporized La atoms resulted in the cleavage of C-O and O-H bonds and the formation of three major products, LaH_2O_2, LaCH_4O_2 and LaC_2H_6O_2, in a supersonic molecular beam. These products were identified by time-of-flight mass spectrometry, and their electronic spectra were obtained using mass-analyzed threshold ionization (MATI) spectroscopy. From the MATI spectra, adiabatic ionization energies of the three complexes were measured to be 40136 (5), 39366 (5) and 38685 (5) cm-1 for LaH_2O_2, LaCH_4O_2 and LaC_2H_6O_2, respectively. The ionization energies of these complexes decrease as the size of the coordinated organic fragments increases. The most active vibrational transitions of all three complexes were observed to be the M-O stretches in the ionic state. A metal-ligand bending mode with a frequency of 127 cm-1 was also observed for [LaH_2O_2]^+. However, the spectra of the other two complexes were less resolved, due to the existence of a large number of low frequency modes, which could be thermally excited even in the supersonic molecular beams, and of multiple rotational isomers formed by the free rotation of the methyl group in these systems. The electronic transitions responsible for the observed spectra were identified as ^1A_1 (C2v) ← ^2A_1 (C2v) for LaH_2O_2 and ^1A (C_1) ← ^2A (C_1) for LaCH_4O_2 and LaC_2H_6O_2.

    2018-04-01

    We began with the newly assembled catalog of literature lithium measurements reported by Barrado et al. (2016, J/A+A/596/A113), who accepted only stars with membership probability >0.75. A small number of Pleiads lie behind an HI cloud, and are thus far more extincted than the rest (e.g., Gordon & Arny 1984AJ.....89..672G); for simplicity, we discard these members. We then cross-correlated this sample with the famous UBV photometric catalog of Johnson & Mitchell (1958ApJ...128...31J), who produced homogeneous photometry for a large sample of Pleiades members. We further selected stars with measured rotation rates, either from the HATNet collaboration (Hartman et al. 2010, J/MNRAS/408/475), or the recent analysis of K2 data (Rebull et al. 2016, J/AJ/152/113, J/AJ/152/114; Stauffer et al. 2016, J/AJ/152/115), preferring the latter for joint detections. Finally, we queried VizieR (http://vizier.u-strasbg.fr/) to obtain KS-band magnitudes from the Two-Micron All-Sky Survey (2MASS) catalog (Skrutskie et al. 2006, Cat. VII/233), which detected every star in our reduced sample. These criteria produced a total of 83 high-probability cluster members, stretching from early-F to late-K type. (3 data files).

    We observed HD 7449 using the Magellan Clay Telescope at the Las Campanas Observatory in Chile on the nights of UT 2014 November 5 and 22. We observed the star with VisAO at Ys (0.99um) and with Clio-2 at H (1.65um) and Ks (2.15um) on the first night and with VisAO at r' (0.63um), i' (0.77um), z' (0.91um), and with Clio-2 at J (1.1um) on the second night. RV data on HD 7449 were first acquired as part of the Magellan Planet Search Program, which originally made use of the MIKE echelle spectrometer (R~70000 in the blue and ~50000 in the red; wavelength coverage ranges from 3900 to 6200Å) on the Magellan Clay telescope until 2009 September. HD 7449 was subsequently observed using the Carnegie Magellan/PFS (3880-6680Å with R~80000 in the iodine region). We also included in our analysis RVs measured with HARPS and CORALIE. These RVs were originally reported in Dumusque et al. (2011, J/A+A/535/A55). HARPS data on HD 7449 has been supplemented by the ESO archive. See section 2.2 for further explanations. (1 data file).

    This study presents Fabry-Perot mapping of M33 obtained at the Observatoire du mont Megantic (OMM). Relano et al. (2013, J/A+A/552/A140) have studied the spectral energy distribution of the H II regions of M33 and the star formation rate and star formation efficiency have been investigated by Gardan et al. (2007A&A...473...91G) and Kramer et al. (2011EAS....52..107K). More than 1000 H II regions can be resolved by the Hα observations; Courtes et al. (1987A&A...174...28C) gave a catalogue of 748 H II regions. Observing those regions allows us to derive the ionized gas (optical) kinematics of M33. Determination of the M33 kinematics with a spatial resolution ~<3 arcsec (~12 pc) using the H{spectra} velocity field and the derivation of an accurate RC in the inner parts are the main goals of this paper. The observations took place at the 1.6-m telescope of the OMM, Quebec, in 2012 September. A scanning FP etalon interferometer has been used during the observations with the device IXON888, a commercial Andor EM-CCD camera of 1024 pixelsx1024 pixels. (1 data file).

    2008-09-01

    We have studied the influence of the stoichiometry on the structural, magnetic, and magneto-optical properties of bismuth iron garnet (Bi3Fe5O12) thin films grown by pulsed laser deposition. Films with different stoichiometries have been obtained by varying the Bi/Fe ratio of the target and the oxygen pressure during deposition. Stoichiometry variations influence the Curie temperature TC by tuning the (Fe)-O-[Fe] geometry: TC increases when the lattice parameter decreases, contrary to what happens in the case of stoichiometric rare-earth iron garnets. The thermal variation of the magnetization, the Faraday rotation, and the Faraday ellipticity have been analyzed in the frame of the Néel two-sublattice magnetization model giving energies of -48K (4.1 meV), -29K (2.5 meV), and 84 K (7.3 meV) for the three magnetic exchange integrals jaa , jdd , and jad , respectively. Magneto-optical spectroscopy linked to compositional analysis by Rutherford backscattering spectroscopy shows that Bi and/or Fe deficiencies also affect the spectral variation (between 1.77 and 3.1 eV). Our results suggest that bismuth deficiency has an effect on the magneto-optical response of the tetrahedral Fe sublattice, whereas small iron deficiencies affect predominantly the magneto-optical response of the octahedral sublattice.

    En 1994, l'attribution du prix Nobel à Cliff Shull et Bert Brockhouse pour leurs travaux de pionniers pendant les années 50, concernant tant la diffusion élastique des neutrons que la diffusion inélastique, a été la reconnaissance éclatante de l'importance de la diffusion neutronique pour toute la communauté scientifique.Le grand intérêt du neutron pour la recherche s'appuie principalement sur ses propriétés physiques particulières :- les neutrons utilisés pour la caractérisation de la matière (et fournis en relativement grandes quantités par les réacteurs ou les sources à spallation) disposent de longueurs d'onde et d'énergies correspondant directement aux distances interatomiques et aux énergies d'agitation de la matière. Ainsi, par diffusion neutronique, on peut étudier en même temps la structure et le comportement dynamique de la matière ;- le fait que le neutron soit doué d'un moment magnétique lui permet d'interagir avec tout atome porteur d'un moment magnétique. Ceci permet de caractériser intimement le comportement magnétique de la matière à l'échelle microscopique ;- la possibilité de pouvoir varier facilement le contraste d'un même élément en utilisant ses différents isotopes fait du neutron un outil irremplaçable en chimie et physique du solide ainsi qu'en biologie et matière molle ;- enfin, n'ayant pas de charge électrique, les neutrons peuvent pénétrer la matière sans être absorbés significativement, ce qui rend possible une caractérisation non destructive des contraintes et textures sur de grosses pièces des matériaux.Toutes les qualités des neutrons mentionnées ci-dessus permettent de comprendre l'importance de la diffusion neutronique pour des domaines très nombreux et très différents à la fois en recherche fondamentale mais aussi pour des applications industrielles. L'utilisation de l'outil-neutron demande toutefois non seulement une bonne connaissance des différents mécanismes d

    Duvert, G.

    2016-11-01

    Several star diameter compilations exist that contain a fair amount of stellar angular diameter measurements. The CADARS (2011, Cat. II/224) has entries for 6888 stars and claims completeness up to 1997. CHARM2 (2005, Cat. J/A+A/431/773) lists 8231 measurements of 3243 stars, up to 2005. However all these catalogs mix results from very direct methods, such as intensity interferometry, with indirect methods, or spectrophotometric estimates of various kind (always including some model of the star), or linear diameters from eclipsing binaries (1600 entries in CADARS), which need some modelling of the two stars, as well as a good estimate of the distance to be converted into an angular diameter. In contrary, the present catalogue, called JMDC (for JMMC Measured stellar Diameters Catalog) is focussed on direct methods only, and selects only one value of the uniform-disk diameter (UDD) and limb-darkened diameter (LDD) for each historical measurement. It should be regularly updated via a specialized submission tool that will be made available on the JMMC website (www.jmmc.fr). The current version gathers 1478 measurements that have been published since the first experiments by Michelson. Prior to 1997, our bibliography relies only on the reference list of CADARS, carefully reviewed. After this date we used NASA's ADS hosted at CDS. We retained only the measurements obtained from visible/IR interferometry, intensity interferometry and lunar occultation in the database. We always retrieved the values in the original text and used SIMBAD to properly and uniquely identify the stars. The three techniques retained share the same method of converting the measurements (squared visibilities for optical interferometry, correlation of photon-counts for intensity interferometry, fast photometry for lunar occultations) into an angular diameter: fitting a geometrical function into the values, in many cases a uniform disk, which provides a uniform disk diameter (UDD) value. This UDD is

    The JMMC (Jean-Marie Mariotti Center) Calibrator Workgroup has long developed methods to estimate the angular diameter of stars, and provides this expertise in the SearchCal tool (http://www.jmmc.fr/searchcal). SearchCal creates a dynamical catalogue of stars suitable to calibrate Optical Long-Baseline Interferometry (OLBI) observations from on-line queries of CDS catalogues, according to observational parameters. In essence, SearchCal is limited only by the completeness of the stellar catalogues it uses, and in particular is not limited in magnitude. SearchCal being an application centered on the somewhat restricted OLBI observational purposes, it appeared useful to make our angular diameter estimates available for other purposes through a CDS-based catalog, the JMMC Stellar Diameters Catalogue (JSDC, II/300). This second version of the catalog represents a tenfold improvement both in terms of the number of objects and on the precision of the estimates. This is due to a new algorithm using reddening-free quantities -- the pseudomagnitudes, allied to a new database of all the measured stellar angular diameters -- the JMDC (II/345/jmdc), and a rigorous error propagation at all steps of the processing. All this is described in the associated publication by Chelli et al. (2016A&A...589A.112C). The catalog reports the Limb-Darkened Diameter (LDD) and error for 465877 stars, as well as their BVRIJHKLMN magnitudes, Uniform Disk Diameters (UDD) in these same photometric bands, Spectral Type, and two supplementary quality indicators: - the mean-diameter chi-square (see Appendix A.2 of Chelli et al., 2016A&A...589A.112C). - a flag indicating some degree of caution in choosing this star as an OLBI calibrator: known spectroscopic binaries, Algol type stars, etc, see Note (1). The conversion from LDD to UDD in each spectral band is made using mainly the coefficients from J/A+A/556/A86/table16 and J/A+A/554/A98/table16 when possible (compatible spectral types) and following the

    NASA Technical Reports Server (NTRS)

    Sakamoto, Jeffrey; Paik, Jong-Ah; Jones, Steven; Nesmith, Bill

    2008-01-01

    This innovation blends the merits of multifoil insulation (MFI) with aerogel-based insulation to develop a highly versatile, ultra-low thermally conductive material called hybrid multifoil aerogel thermal insulation (HyMATI). The density of the opacified aerogel is 240 mg/cm3 and has thermal conductivity in the 20 mW/mK range in high vacuum and 25 mW/mK in 1 atmosphere of gas (such as argon) up to 800 C. It is stable up to 1,000 C. This is equal to commercially available high-temperature thermal insulation. The thermal conductivity of the aerogel is 36 percent lower compared to several commercially available insulations when tested in 1 atmosphere of argon gas up to 800 C.

  3. Non-linearite et couplages lumiere-matiere en electrodynamique quantique en circuit

    NASA Astrophysics Data System (ADS)

    Bourassa, Jerome

    L'électrodynamique quantique en circuit est un contexte unique pour l'optique quantique et le calcul quantique. Dans cette architecture où des qubits supraconducteurs, composés de jonctions Josephson, sont fortement couplés au champ électromagnétique de résonateurs coplanaires, la dynamique du système est semblable à celle des atomes dans des cavités optiques. La polyvalence de la conception des circuits supraconducteurs permet d'étudier l'interaction lumière-matière de différents régimes et manières. Ainsi, plusieurs qubits peuvent être couplés à un seul résonateur afin de les enchevêtrer. Une jonction Josephson peut également être intégrée directement au résonateur afin de produire une interaction non linéaire entre les photons. De la même manière, il a été suggéré que le couplage qubitrésonateur pourrait devenir l'échelle d'énergie dominante du système : le régime de couplage ultrafort. Malgré que la dynamique qubit-résonateur soit bien comprise, les modèles actuels ne permettent pas de prédire correctement les effets dispersifs du résonateur sur les qubits tels : le décalage de Lamb, l'interaction d'échange virtuelle et le temps de relaxation. Comme il n'y a pas non plus de modèle général permettant de déterminer les caractéristiques d'un résonateur non linéaire, on comprend mal comment rendre la non-linéarité plus forte, ni même si le régime de couplage ultrafort peut être physiquement réalisé dans ces circuits. Dans le cadre de ma thèse, je me suis intéressé à la modélisation de qubits et de résonateurs afin de mieux comprendre l'interaction lumière-matière en circuits, dans le but de développer des conceptions alternatives d'architectures plus performantes ou qui explorent des régimes d'interactions méconnus. Pour ce faire, j'ai développé une méthode analytique générale permettant de trouver l'hamiltonien exact de circuits distribués non linéaires, une méthode basée sur la m

    Résumé Objectif Mettre à jour les Lignes directrices consensuelles canadiennes 2011 en matière de soins primaires aux adultes ayant une déficience développementale. Méthodes Des médecins de famille et d’autres professionnels de la santé expérimentés dans les soins aux personnes ayant des DID ont examiné et synthétisé les récentes connaissances empiriques, d’écosystèmes, expertes et expérientielles. Un système a été conçu pour catégoriser la qualité des recommandations. Recommandations Les adultes ayant des DID sont un groupe hétérogène de patients qui présentent des affections médicales et des facteurs qui influent sur leur santé, qui diffèrent de ceux qui touchent les autres membres de la communauté de par leur nature, leurs manifestations, leur gravité ou leur complexité. Ces personnes nécessitent une approche de soins et des interventions adaptées à leurs besoins. Les présentes lignes directrices offrent des conseils en matière de normes de soins. Nous avons incorporé des références à des outils cliniques et à d’autres ressources pratiques. Les approches de soins décrites ici s’appliquent aussi à d’autres groupes de patients ayant un déficit cognitif ou de la communication, ou d’autres déficits des fonctions adaptatives. Conclusion À titre de fournisseurs de soins de première ligne, les médecins de famille jouent un rôle vital de promotion de la santé et de bien-être auprès des adultes ayant des DID. Ces lignes directrices peuvent les aider à prendre des décisions avec les patients et les aidants naturels. PMID:29650617

  7. Update on SLD Engineering Tools Development

    2004-01-01

    The airworthiness authorities (FAA, JAA, Transport Canada) will be releasing a draft rule in the 2006 timeframe concerning the operation of aircraft in a Supercooled Large Droplet (SLD) environment aloft. The draft rule will require aircraft manufacturers to demonstrate that their aircraft can operate safely in an SLD environment for a period of time to facilitate a safe exit from the condition. It is anticipated that aircraft manufacturers will require a capability to demonstrate compliance with this rule via experimental means (icing tunnels or tankers) and by analytical means (ice prediction codes). Since existing icing research facilities and analytical codes were not developed to account for SLD conditions, current engineering tools are not adequate to support compliance activities in SLD conditions. Therefore, existing capabilities need to be augmented to include SLD conditions. In response to this need, NASA and its partners conceived a strategy or Roadmap for developing experimental and analytical SLD simulation tools. Following review and refinement by the airworthiness authorities and other international research partners, this technical strategy has been crystallized into a project plan to guide the SLD Engineering Tool Development effort. This paper will provide a brief overview of the latest version of the project plan and technical rationale, and provide a status of selected SLD Engineering Tool Development research tasks which are currently underway.

    We analyzed 1600 spectra of NGC 5548 in the Hβ spectral interval, covering 43 years. We used: (a) archival spectra obtained by K.K. Chuvaev from 1972-1988 (Sergeev+ 2007ApJ...668..708S) prior to the International AGN Watch (IAW) campaigns. These early spectra were recorded on photographic plates acquired with an image tube at the 2.6m Shajn Telescope of the Crimean Astrophysical Observatory. (b) The 13 year study (from 1988 to 2002) of the IAW program (Peterson+ 2002ApJ...581..197P), which provided 1530 optical continuum measurements and 1248 Hβ measurements. (c) A spectral monitoring program with the 6 and 1m telescopes of the Special Astrophysical Observatory (SAO) in Russia from 1996 to 2002, and the 2.1m telescope of Guillermo Haro Observatory (GHO) in Cananea, Mexico, from 1996 to 2003 (S04; Shapovalova+ 2004, J/A+A/422/925). (d) More recent, unpublished observations of the same program covering 2003-2013 observed at SAO (see Table 1), and a continuation of the monitoring campaign presented in S04. (e) Spectra from the new IAW campaign obtained at Asiago observatory in 2012, 2013, and 2015. (f) New unpublished observations from 2013 from the Asiago observatory (also given in Table 1).

    6006 differential positions of the main Saturnian satellites issued from astrometric measurements of CCD observations performed in 1995 at the Laboratorio Nacional de Astrofisica at Itajuba in Brazil. Most of these frames have no reference stars, then we applied an inter-satellites reduction. We have used the positions of Tethys, Dione, Rhea and Titan given by TASS1.7 to determine the scale factor and the orientation of the receptor (1995A&A...297..588V, 1997 Cat. <J/A+A/324/366>). The comparison of the observed positions and the computed positions shows that the dispersion of the observations is 0.07". Furthermore, the quality and the number of the positions of the satellites not used in the calibration is good: 0.08" for the 216 positions of Mimas, 0.14" for Hyperion (324), 0.11" for Iapetus (524). The format and the conventions of the present catalog are very near to the one of Strugnell & Taylor (1990A&AS...83..289S). The coordinates are given apart from a scale factor and from a rotation, but all astrometric corrections are done. So, these positions are really astrometric ones in that meaning that, no astrometric consideration is necessary to use them, even if one wants to touch up the calibration. Nevertheless, the raw pixels are also given in order to allow anyone to reduce again the frames. (1 data file).

    All the data used in this paper were acquired with the X-shooter spectrograph at the VLT. The capabilities of X-shooter in terms of wide spectral coverage (310-2500nm), resolution and limiting magnitudes allow us to assess simultaneously the mass accretion and outflow, and disc diagnostics, from the UV and optical to the near IR. The sample studied in this paper consists mainly of two sets of low-mass class II YSOs in the aforementioned Lupus clouds. The first one comprises the 36 objects published in Alcala et al, (2014, Cat. J/A+A/561/A2), observed within the context of the X-shooter INAF/GTO (Alcala et al. 2011AN....332..242A) project; for simplicity we will refer to it as the "GTO sample" throughout the paper. One additional source namely Sz105, was investigated with X-shooter during the GTO, but rejected as a legitimate YSO (see below). The second sample consists of 49 objects observed during ESO periods 95 and 97 (1 April-30 September 2015 and 1 April-30 September 2016, respectively). In addition, we include here six objects observed with X-shooter in other programmes taken from the ESO archive. In total, 55 objects were newly analysed here and we will refer to them as the "new sample". (12 data files).

    Le neutron est une particule élémentaire qui a été découverte en 1932 par James Chadwick. Ses caractéristiques principales sont résumées dans le tableau I. Il a été utilisé pour la première fois par Clifford Shull en 1946 comme outil pour des expériences de diffusion. Cette technique s'est depuis constamment développée pour concerner tous les aspects de la matière condensée: physique, chimie, matériaux, biologie. Il s'agit d'un outil tout à fait exceptionnel car le neutron possède des propriétés uniques et particulièrement adaptées pour ces études.

    2008-01-01

    RÉSUMÉ La recherche en santé est un devoir moral parce qu’elle est la base des soins probants prodigués par tous les dispensateurs de soins. Des politiques et des règlements précis régissent la tenue des recherches sur des humains. Il faut procéder à une évaluation éthique d’un projet de recherche donné avant de pouvoir l’entreprendre. La recherche sur les enfants pose d’énormes défis en matière de consentement éclairé et d’assentiment, de vulnérabilité et de potentiel de conflit d’intérêts (CDI). Les chercheurs en santé pédiatrique devraient prôner la participation des enfants à la recherche, tout en se montrant attentifs à en limiter les risques.

    Spectroscopic redshifts for 1303 galaxies within a 2-degree field around Abell 3266. Redshifts are listed for 880 galaxies observed with the 2dF instrument on the Anglo-Australian Telescope (Dehghan et al., 2017, this paper), 391 objects from the compilation of Quintana et al. (1996, Cat. J/AJ/112/36), 264 objects from the WIde-field Nearby Galaxy-cluster Survey (WINGS; Cava et al., 2009, Cat. J/A+A/495/707), and an additional 39 objects from various works in the literature within one degree of the nominal centre of A3266. The 880 galaxies from the 2dF sample were observed on 29 December 1997 and 5 October 1999. Four fibre configurations were observed, all covering a single 2-degree-diameter field around the nominal cluster centre of RA=04:31:09.7, DE=-61:28:40 (J2000). The data were reduced with the 2dfdr pipeline reduction software for 2dF, and redshifts were measured using a modified version of the program used for the 2dF Galaxy Redshift Survey (Colless et al., 2001MNRAS.328.1039C, Cat. VII/226). The positions of the AAO catalogue come from the UK Schmidt Telescope southern sky survey plate for field F118, scanned with the Automated Plate Measuring machine (Maddox et al., 1990MNRAS.243..692M). Full details can be found in the paper. (1 data file).

    The cornerstone data set for the COSMOS survey is its wide-field HST Advanced Camera for Surveys (ACS) imaging (Scoville et al. 2007ApJS..172...38S). With 583 single-orbit HST ACS F814W (I band; hereafter I814) observations, it is the largest contiguous HST imaging survey to date. The VLA-COSMOS large project (Schinnerer et al., 2007, Cat. J/ApJS/172/46) acquired deep, uniform 1.4GHz data over the entire COSMOS field using the A-array configuration of the Very Large Array (VLA). The XMM-Newton COSMOS survey (Hasinger et al., 2007, Cat. J/ApJS/172/29; Cappelluti et al., 2009, Cat. J/A+A/497/635) acquired deep X-ray data over the entire COSMOS HST ACS field. The S-COSMOS survey (Sanders et al., 2007ApJS..172...86S) is a Spitzer Legacy program which carried out a uniformly deep survey of the full COSMOS field in seven mid-IR bands (3.6, 4.5, 5.8, 8.0, 24, 70, and 160um). The Advanced Camera for Surveys General Catalog2 (ACS-GC) data (R.L. Griffith et al., 2012ApJS..200....9G) was constructed to study the evolution of galaxy morphologies over a wide range of look-back times. The ACS-GC uniformly analyzes the largest HST ACS imaging surveys (AEGIS, GEMS, GOODS-S, GOODS-N, and COSMOS) using the GALAPAGOS code. (3 data files).

    Introduction Le phénomène de vieillissement des populations est associé à une augmentation de la prévalence de la morbidité liée à l’âge. La prescription des psychotropes chez le sujet âgé est de plus en plus fréquente dans les institutions, les doses sont de plus en plus élevées, avec un recours fréquent à une poly pharmacothérapie. Nous nous sommes proposé de décrire les conduites thérapeutiques chez le sujet âgé consultant en psychiatrie, en vue de les confronter aux dernières recommandations en la matière. Méthodes L’étude était de type rétrospectif et descriptif. Elle a concerné les sujets âgés d'au moins 60 ans ayant consulté pour la première fois en psychiatrie, au CHU Hédi Chaker à Sfax, en 2010 ou 2011. Résultats Nous avons colligé 159 dossiers. L’âge moyen était de 73 ans. La démence et les troubles de l'humeur étaient les diagnostics les plus fréquents. Sur le plan thérapeutique, une poly thérapie faite d'au moins deux psychotropes de familles différentes a été prescrite pour 55,9%. Chez 60.3% des sujets, le traitement a été prescrit d'emblée à dose complète. Aucun dossier ne faisait état d'une prise en charge psychothérapeutique. Conclusion La prise en charge des malades de notre étude n’était pas conforme aux recommandations, notamment en matière d'association médicamenteuse, de progression des doses et d'association de la psychothérapie à la pharmacothérapie. L'information des médecins et leur sensibilisation aux particularités du sujet âgé contribuerait à optimiser les soins qui leur sont prodigués, y compris en psychiatrie. PMID:25120873

    The brain is a complex spatio-temporal affair. Several brain theories propose the definition of three superposed levels of study. But physics, though the experience of condensed matter physics, suggests that it is unwise to enforce onto brain theories a unified hierarchical scheme, the inspiration for which seems to come from the realm of sub-molecular physics. Le cerveau est une affaire spatio-temporelle complexe. Plusieurs théories du cerveau proposent de définir trois niveaux d'études superposés. Mais la physique, à travers l'expérience de la physique de la matière condensée, suggère qu'il n'est pas sage d'imposer sur les théories du cerveau un schéma hiérarchique unifié, dont l'inspiration semble provenir du domaine de la physique sub-moléculaire.

    Résumé Le patient a le droit d’être informé sur les soins de santé qui lui sont proposés et de participer activement à la prise de décisions relativement à ces soins. Le respect de la dignité et de l’autonomie de la personne passe par le respect de son droit de prendre des décisions à propos de ses soins psychiatriques, notamment de refuser un traitement, pour autant qu’elle soit apte à prendre des décisions. Il importe que le psychiatre connaisse les fondements éthiques du consentement libre et éclairé et les exigences prévues par le droit en cette matière, y compris la jurisprudence. Le consentement n’est pas immuable, pouvant changer avec le temps, au fil de l’évolution des conditions et des circonstances. Par conséquent, le consentement doit être un processus continu.

  5. Overcoming the Challenges of Implementing a Multi-Mission Distributed Workflow System

    2009-01-01

    A multi-mission approach to solving the same problems for various projects is enticing. However, the multi-mission approach leads to the need to develop a configurable, adaptable and distributed system to meet unique project requirements. That, in turn, leads to a set of challenges varying from handling synchronization issues to coming up with a smart design that allows the "unknowns" to be decided later. This paper discusses the challenges that the Multi-mission Automated Task Invocation Subsystem (MATIS) team has come up against while designing the distributed workflow system, as well as elaborates on the solutions that were implemented. The first is to design an easily adaptable system that requires no code changes as a result of configuration changes. The number of formal deliveries is often limited because each delivery costs time and money. Changes such as the sequence of programs being called, a change of a parameter value in the program that is being automated should not result in code changes or redelivery.

    2011-03-01

    Neutron activation analysis (NAA), based on the comparator method, has the potential to fulfill the requirements of a primary ratio method as defined in 1998 by the Comité Consultatif pour la Quantité de Matière — Métrologie en Chimie (CCQM, Consultative Committee on Amount of Substance — Metrology in Chemistry). This thesis is evidenced in this paper in three chapters by: demonstration that the method is fully physically and chemically understood; that a measurement equation can be written down in which the values of all parameters have dimensions in SI units and thus having the potential for metrological traceability to these units; that all contributions to uncertainty of measurement can be quantitatively evaluated, underpinning the metrological traceability; and that the performance of NAA in CCQM key-comparisons of trace elements in complex matrices between 2000 and 2007 is similar to the performance of Isotope Dilution Mass Spectrometry (IDMS), which had been formerly designated by the CCQM as a primary ratio method.

    In May 2000, the chairman of the European Radiation Dosimetry Group (EURADOS) invited a number of experts with experience of cosmic radiation dosimetry to form a working group (WG 5) on aircraft crew dosimetry. Three observers from the Article 31 Group of Experts as well as one observer from the Joint Aviation Authorities (JAA) were also appointed. The European Commission funded the meetings. Full meetings were organised in January 2001 and in November 2001. An editorial group, who are the authors of this publication, started late in 2002 to finalise a draft report, which was submitted to the Article 31 Group of Experts in June 2003. The methods and data reported are the product of the work of 26 research institutes from the EU, USA and Canada. Some of the work was supported by contracts with the European Commission, Directorate General XII, Science, Research and Development. A first overview of the EC report was published late in 2004. In this publication we focus on a comparison of measured and calculated ambient dose rate data using the EURADOS In-Flight Data Base. The evaluation of results obtained by different methods and groups, and comparison of measurement results and the results of calculations were performed in terms of the operational quantity ambient dose equivalent, H*(10). Aspects of measurement uncertainty are reported also. The paper discusses the estimation of annual doses for given flight hours and gives an outline of further research needed in the field of aircraft crew dosimetry, such as the influence of solar particle events.

    Finite-size (d = 5.4-112 nm) and surface effects on the structural, optical, and magnetic properties of ferrimagnetic inverse-spinel MnCo2O4 are reported. For d ≥ 87 nm, partial tetragonal distortion of the inverse spinel-lattice was observed. The Curie temperature TC of MnCo2O4 nanostructures, as determined by dc-magnetic susceptibility (χ) measurements, follows a finite-size scaling relation TC(d) = TC(∞)[1-(ξ0/d)λ] with a shift exponent λ = 0.75 ± 0.15 and microscopic correlation length ξ0 = 1.4 ± 0.3 nm, which is consistent with the mean field theory. For T > TC, χ(T) fits Néel's expression for the two-sublattice model with antiferromagnetic molecular field (exchange) constants NBB ˜ 85.16 (JBB ˜ 2.94 × 10-22 J), NAB ˜ 110.96 (JAB ˜ 1.91 × 10-22 J), and NAA ˜ 43.8 (JAA ˜ 1.13 × 10-22 J) and asymptotic Curie temperature Ta ˜ 717.63 K. The optical energy bandgap Eg, evaluated from the Kubelka-Munk function ( [ F ( R ∞ ) ℏ ω ] 2 = C2( ℏ ω - Eg)) is blueshifted to 2.4 eV (d ˜ 5.4 nm) from 1.73 eV (d ˜ 112 nm) due to the quantum confinement and non-stoichiometry. The role of tetragonal distortion and grain-size-effects in the intensity of crystal field transitions and variation in the magnetic ordering are further discussed and compared with Co3O4 nanostructures.

    In recent years, some theoretical interests have been focused on the binary alloy nanotubes and nanowires with mixed spins. Compared with ferrimagnetic nanowires, few studies have been done on ferrimagnetic nanotubes. In this paper, the magnetic properties of a mixed spin-(2, 3/2) Heisenberg single-walled nanotube superlattice are calculated by use of the double-time Green's function method within the random phase approximation and the Anderson and Callen's decoupling. Magnetic compensation and critical properties are obtained for a wide range of parameters in the Hamiltonian, and magnetic phase diagrams are plotted in the related planes. For Heisenberg single-walled nanotube superlattice model with Néel-type magnetic structure, anisotropy must be taken into account, and the easy-axis single-ion anisotropy is considered in this paper. The next nearest neighbor exchange interactions Jbb and/or single-ion anisotropy strength Db of the smaller spin sublattice were necessary in order to obtain a compensation point. The influence of the wall diameter number of the tubes, m, an important parameter of the system, on the compensation behavior is considered. Calculation shows that as Jbb and Db are fixed, only when m is beyond a certain minimum value, mmin, can compensation temperature Tcom appears, where the next nearest neighbor exchange interactions Jaa and single-ion anisotropy strength Da of the larger spin sublattice are absent. The compensation temperature and critical temperature increase with m rising, which indicates that the longitudinal correlation effect is enhanced and the fluctuation effect is weakened with the increase of m.

  10. Future aeromedical assessment in general aviation: a contribution to the actual discussion

    The past years saw a transition of competencies from the Joint Aviation Authorities (JAA) to the European Aviation Safety Agency (EASA), which was founded in 2003, based on EU Regulation 1592/02. EASA started its work in the fields of Airworthiness and will soon its competencies inter alia to Flight Operations and Flight Crew Licensing, the latter including the requirements for aeromedical assessment. The appropriate new EU Regulation will most probably be published in April. It includes the Essential Requirements for Licensing and aeromedical certification. A proposal for a new Commission Regulation promulgates the Implementing Rules for Personnel Licensing, detailing – inter alia – the Medical Requirements (Annex II to the Regulation). The specific rules, numeric standards are published as Acceptable Means of Compliance (AMC) and Guidance Material (GM). The provisions are based on JAR-FCL 3 and have been transposed to the format choosen by EASA by a small working group of aeromedical experts (FCL.001). Comments received by the European Aviation Safety Agency (EASA) prompted the agencys statement that the JAR-FCL 3 requirements for private pilots were excessive and too demanding and that a better regulation in General Aviation had to be developed. Another working group (MDM.032), including one aeromedical specialist, was tasked to draft a set of lighter requirements for non-complex aircraft used in non-commercial operations. In this context a much lighter form of aeromedical assessment - involving self-declaration by the pilot and general practitioners as asessors – has been proposed. PMID:19048096

    Résumé Objectif Comparer les connaissances et l’utilisation des recommandations concernant la prise en charge de la commotion dans le sport (CDS) démontrées par les spécialistes de la médecine du sport et de l’exercice (SMSE) et les urgentologues afin d’évaluer la réussite du transfert des connaissances sur la CDS au Canada. Conception Un sondage à choix multiples envoyé par courriel et autoadministré par des SMSE et des urgentologues. La validité du contenu du sondage a fait l’objet d’une évaluation. Contexte Canada. Participants Le sondage a été complété entre mai et juillet 2012 par des SMSE qui ont réussi l’examen menant au diplôme de l’Académie canadienne de la médecine du sport et de l’exercice et des urgentologues qui n’avaient pas ce diplôme. Principaux paramètres à l’étude La connaissance et l’identification des sources d’information sur la prise en charge des commotions, l’utilisation des stratégies de diagnostic de la commotion et l’utilisation d’une terminologie courante et cohérente dans l’explication des stratégies de repos aux patients après une CDS. Résultats Le taux de réponse était de 28 % (305 sur 1085). Les taux de réponse par les SMSE et les urgentologues se situaient respectivement à 41 % (147 sur 360) et 22 % (158 sur 725). Parmi les répondants, 41 % des urgentologues et 3 % des SMSE n’étaient pas au courant de l’existence de déclarations consensuelles sur la commotion dans le sport; 74 % des SMSE utilisaient « habituellement ou toujours » la version 2 de l’Outil d’évaluation de la commotion dans le sport (SCAT2), tandis que 88 % des urgentologues n’utilisaient jamais le SCAT2. Aucune réponse uniforme n’a été documentée à la question visant à connaître les meilleurs modes de repos cognitif. Conclusion Nous avons cerné des différences et un manque d’uniformité chez les SMSE et les urgentologues dans la mise en application des recommandations concernant les patients ayant subi une CDS. Il semble que le SCAT2 soit davantage utilisé dans le milieu des SMSE que dans le contexte de l’urgence. Des efforts plus poussés de transfert des connaissances et en recherche devraient atténuer les obstacles à des conseils plus uniformes donnés par les médecins qui soignent des patients ayant subi une CDS.

    We chose to locate S-CANDELS inside the wider and shallower fields already covered by Spitzer Extended Deep Survey (SEDS), in regions that enjoy deep optical and NIR imaging from HST/CANDELS. These S-CANDELS fields are thus the Extended GOODS-south (aka the GEMS field, hereafter ECDFS; Rix et al. 2004ApJS..152..163R; Castellano et al. 2010A&A...511A..20C), the Extended GOODS-north (HDFN; Giavalisco et al. 2004, II/261; Wang et al. 2010, J/ApJS/187/251; Hathi et al. 2012ApJ...757...43H; Lin et al. 2012ApJ...756...71L), the UKIDSS UDS (aka the Subaru/XMM Deep Field, Ouchi et al. 2001ApJ...558L..83O; Lawrence et al. 2007, II/319), a narrow field within the EGS (Davis et al. 2007ApJ...660L...1D; Bielby et al. 2012A&A...545A..23B), and a strip within the UltraVista deep survey of the larger COSMOS field (Scoville et al. 2007ApJS..172...38S; McCracken et al. 2012, J/A+A/544/A156). The S-CANDELS observing strategy was designed to maximize the area covered to full depth within the CANDELS area. Each field was visited twice with six months separating the two visits. Table 1 lists the epochs for each field. All of the IRAC full-depth coverage is within the SEDS area (Ashby et al. 2013, J/ApJ/769/80), and almost all is within the area covered by HST for CANDELS.

    This is a catalogue of distances and their asymmetric uncertainties inferred from the parallaxes published in the Gaia DR1 catalogue. Two priors are used: The exponentially decreasing space density and the Milky Way prior. For the exponentially decreasing space density prior, two scale lengths are used: 110pc and 1350pc. The former is based on a fitting of the true distance distribution of a subset of the GUMS catalogue (Robin et al., 2012, Cat. VI/137) which are limited to V<11. This is the magnitude at which Tycho-2 is 99% complete. The latter is based on the same procedure but limited to G=20.7, which is the expected limiting magnitude of Gaia. For the Milky Way prior, the parameters are described in the paper. We report the mode of the posterior PDF, the median, the 90% credible interval, and a standard deviation in distance which are calculated by scaling the 90% into 68.3%. The Cepheids data used for the validation of the results are included here as well. They are taken from Groenewegen (2013, Cat. J/A+A/550/A70) and cross-matched with Hipparcos and/or Tycho by making a Simbad query of each Cepheids and finding the corresponding Hipparcos and/or Tyho identifier. The distances are inferred either by neglecting the systematic uncertainties of 0.3mas (Gaia Collaboration et al., 2016, Cat. I/337) for reasons described in the paper, or by adding a systematic uncertainties of 0.3mas in quadrature with the random parallax uncertainties. We provide both results here. (4 data files).

    The Herschel Terahertz Large Area survey (H-ATLAS) is the largest Open Time Key Project carried out with the Herschel Space Observatory (Eales et al., 2010PASP..122..499E), covering an area of 550 deg2 in five far-infrared and sub-millimeter (submm) bands (100, 160, 250, 350, and 500um). 16 deg2 have been presented in the Science Demonstration Phase (SDP) catalogue (Rigby et al., 2011, Cat. J/MNRAS/415/2336) and lie within one of the regions observed by the Galaxy And Mass Assembly (GAMA) survey (Driver et al. 2011, Cat. J/MNRAS/413/971; Baldry et al. 2010MNRAS.404...86B). XMM-Newton observed 7.1 deg2 with a total exposure time of 336ks (in the MOS1 camera) within the H-ATLAS SDP area, making the XMM-ATLAS one of the largest contiguous areas of the sky with both XMM-Newton and Herschel coverage. The catalogue contains 1816 unique sources (Ranalli et al. 2015, Cat. J/A+A/577/A121). To obtain optical, mid-IR, and far-IR photometry for the XMM-ATLAS sources, we cross-matched the X-ray catalogue with the SDSS-DR13 (Albareti et al., 2015, Cat. J/MNRAS/452/4153), the WISE (Wright et al. 2010AJ....140.1868W, See Cat.

    Two complete transits of WASP-57 were observed using the 1.54 m Danish Telescope and DFOSC instrument at ESO La Silla, Chile (see Dominik et al. 2010AN....331..671D), on the dates 2014/05/18 and 2014/06/24. Both transits were obtained through a Bessell R filter. The transit on 2014/06/24 observed with DFOSC was also monitored using GROND (Greiner et al. 2008PASP..120..405G) mounted on the MPG 2.2 m telescope at La Silla, Chile. GROND was used to obtain light curves simultaneously in four passbands, which approximate the SDSS g, r, i and z bands. We observed WASP-57 on the night of 2012/05/10 using the BUSCA instrument on the 2.2 m telescope at Calar Alto Astronomical Observatory. BUSCA is capable of observing simultaneously in four passbands, for which we chose Gunn u, g, r and z. One transit of WASP-57 was observed on 2012/04/01 with EulerCam, using the same methods as for the EulerCam transit in Faedi et al. (2013, J/A+A/551/A73). We obtained 212 images through a Gunn r filter, without applying a defocus to the instrument. Two transits of WASP-57 were observed on 2012/03/15 and 2012/04/01 using the 0.6 m TRAPPIST robotic telescope located at La Silla (Gillon et al. 2011EPJWC..1106002G; Jehin et al. 2011Msngr.145....2J). Images were obtained with a slight defocus and through a blue-blocking filter that has a transmittance greater than 90 per cent from 500 nm to beyond 1000 nm. (1 data file).

    Les peuples des Premières nations, inuits et métis qui habitent au Canada sont aux prises avec de profondes disparités en matière de santé par rapport aux Canadiens non autochtones, et ce, dans presque toutes les mesures liées à la santé et au bien-être. Pour faire progresser les services de santé auprès des peuples autochtones, il faut passer à l'action dans tous les ordres de prestation des soins et des politiques en santé. Il est donc essentiel que les leaders et les prestataires des établissements, des systèmes et des installations de santé du Canada comprennent et prennent en main les déterminants de la santé propres aux peuples autochtones, y compris l'héritage du colonialisme et le racisme ancien et actuel. La Commission de vérité et réconciliation du Canada est le point de départ pour réagir de manière positive aux injustices.

    The model has six parameters to describe the opacities: - {kappa}(N) is the Rosseland mean opacity at each levels of the atmosphere it does not have to be constant with depth. - Gp is the ratio of the thermal Plank mean opacity to the thermal Rosseland mean opacity. - Beta is the width ratio of the two thermal bands in the frequency space. - Gv1 is the ratio of the visible opacity in the first visible band to the thermal Rosseland mean opacity - Gv2 is the ratio of the visible opacity in the second visible band to the thermal Rosseland mean opacity - Gv3 is the ratio of the visible opacity in the second visible band to the thermal Rosseland mean opacity Each visible band has a fixed width of 1/3. Additional parameters describe the physical setting: - Teq0 is the equilibrium temperature of the planet for 0 albedo and full redistribution of energy. - mu is the angle between the vertical direction and the stellar direction. For average profiles set mu=1/sqrt(3) - f is a parameter equal to 0.5 to compute a dayside average profile and 0.25 for planet average profile. - Tint is the internal temperature, given by the internal luminosity - grav is the gravity of the planet - Ab is the Bond albedo of the planet - P(i) are the pressure levels where the temperature is computed. - N is the number of atmospheric levels. Several options are available in order to use the coefficients derived in Parmentier et al. (2014A&A...562A.133P, Cat. J/A+A/562/A133): ROSS can take the values : - "USER" for a Rosseland mean opacity set by the user {kappa}(nlevels) through the atmosphere. - "AUTO" in order to use {kappa}(P,T), the functional form of the Rosseland mean opacities provided by Valencia et al. (2013ApJ...775...10V) and based on the opacities calculated by Freedman et al. (2008ApJS..174..504F). The value of {kappa} is then recalculated and the initial value set by the user is NOT taken into account. COEFF can take the values : - "USER" for coefficients set by the user - "AUTO" for

    The catalog contains 1273 proven or probable Large Magellanic Cloud (LMC) members, identified on plates taken with the Curtis-Schmidt telescope at Cerro Tololo Inter-American Observatory in Chile. The stars are generally brighter than photographic magnitude 14 and are identified on charts published by Hodge and Wright (1967) and reproduced in the source publication (1970CoTol..89....1S). Approximate spectral types were determined by examination of the 580 Angstroms/mm (at H{gamma}) objective-prism spectra; approximate 1975 positions were obtained by measuring relative to the 1975 coordinate grids on the Uppsala-Mount Stromlo Atlas of the LMC (Gascoigne and Westerlund 1961), and approximate photographic magnitudes were determined by averaging image density measures from the plates and image-diameter measures on the "B" charts of Hodge and Wright (1967SAOP.4699....1H). The catalog includes an identification number (Sk), HD(E) number, Cape Photographic Durchmusterung number, right ascension and declination (equinox B1975), spectral type, photographic magnitude, and alternate identifications. The machine version, updated in September 1986, includes corrections supplied by the author in 1985; thus, it differs somewhat from the published version. Accurate positions, and cross-identifications with the modern surveys, were determined by Brian Skiff in 2008, and make up the "sk_pos.dat" file. This work is based on a file prepared through great effort by Mati Morel in 1999. Brian Skiff examined every object on DSS cut-outs to make sure the star chosen matched the Sanduleak charts. The Goddard SkyView utility was used, looking at an 0.07{deg} (4'x4') field from the DSS1 (short-V plate), DSS2 far-red, and 2MASS J-band images. These three have the shallowest effective exposure (these are bright stars!), and usually the best image quality to check for companions etc as well as star colors. Precise coordinates were then obtained via VizieR mainly from UCAC2, but occasionally

  20. The actual development of European Aviation Safety Requirements in Aviation Medicine: Prospects of Future EASA Requirements

    PubMed Central

    Siedenburg, J

    2009-01-01

    Common Rules for Aviation Safety had been developed under the aegis of the Joint Aviation Authorities in the 1990ies. In 2002 the Basic Regulation 1592/2002 was the founding document of a new entity, the European Aviation Safety Agency. Areas of activity were Certification and Maintenance of aircraft. On 18 March the new Basic Regulation 216/2008, repealing the original Basic Regulation was published and applicable from 08 April on. The included Essential Requirements extended the competencies of EASA inter alia to Pilot Licensing and Flight Operations. The future aeromedical requirements will be included as Annex II in another Implementing Regulation on Personnel Licensing. The detailed provisions will be published as guidance material. The proposals for these provisions have been published on 05 June 2008 as NPA 2008- 17c. After public consultation, processing of comments and final adoption the new proposals may be applicable form the second half of 2009 on. A transition period of four year will apply. Whereas the provisions are based on Joint Awiation Requirement - Flight Crew Licensing (JAR-FCL) 3, a new Light Aircraft Pilot Licence (LAPL) project and the details of the associated medical certification regarding general practitioners will be something new in aviation medicine. This paper consists of 6 sections. The introduction outlines the idea of international aviation safety. The second section describes the development of the Joint Aviation Authorities (JAA), the first step to common rules for aviation safety in Europe. The third section encompasses a major change as next step: the foundation of the European Aviation Safety Agency (EASA) and the development of its rules. In the following section provides an outline of the new medical requirements. Section five emphasizes the new concept of a Leisure Pilot Licence. The last section gives an outlook on ongoing rulemaking activities and the opportunities of the public to participate in them. PMID:19561781

    The aim of this study was to investigate the association between pregnancy complications, mental health-related problems, and type 2 diabetes mellitus (T2DM) in Malaysian women. A case-control study of women with T2DM (n=160) matched by age range to controls without T2DM (n=160). Data were collected in the Negeri Sembilan and PutraJaya regions in Malaysia, from two hospital outpatient clinics, PutraJaya Hospital and Tuanku Jaa'far Hospital Seremban, and one health clinic at Seremban. Validated, interviewer-administered questionnaires were used to obtain the data. The unadjusted and adjusted estimates were calculated using the Mantel-Haenszel method. Neither depression (RR 0.74, 95% CI: 0.39-1.41) nor anxiety (RR 1.00, 95% CI: 0.53-1.88) symptoms increased the risk of T2DM significantly. However, gestational diabetes (RR 1.35, 95% CI: 1.02-1.79), and ≥3 pregnancies (RR 1.39, 95% CI: 1.08-1.79) were significant risk factors for the development of T2DM. T2DM was not a significant risk factor for either depression (RR 1.26, 95% CI: 0.91-1.74) or anxiety symptoms (RR 1.13, 95% CI: 0.59-2.19). In this study, T2DM is not a significant risk factor for depression and anxiety; similarly, neither are depression and anxiety significant risk factors for T2DM. Although prevalence of depression and anxiety is not alarming, the findings reported here should alert clinicians to screen and treat anxiety and depression in people with diabetes and also note the importance of monitoring women with complications in pregnancy for risk of later T2DM.

    We have compiled a sample of all radio-quiet quasars or quasars without radio detection from the Veron-Cetty - Veron catalogue (1993, VV93, Cat. ) detected by ROSAT in the ALL-SKY SURVEY (RASS, Voges 1992, in Proc. of the ISY Conference `Space Science', ESA ISY-3, ESA Publications, p.9, See Cat. ), as targets of pointed observations, or as serendipitous sources from pointed observations publicly available from the ROSAT point source catalogue (ROSAT-SRC, Voges et al. 1995, Cat. ). For all sources we used the results of the Standard Analysis Software System (SASS, Voges et al. 1992, in Proc. of the ISY Conference `Space Science', ESA ISY-3, ESA Publications, p.223), employing the most recent processing for the Survey data (RASS-II, Voges et al. 1996, Cat. ). The total number of quasars is 846. 69 of the radio-quiet objects with radio detections have already been presented in a previous paper (Brinkmann, Yuan, & Siebert 1997, Cat. <J/A+A/319/413>) using the RASS-I results. 17 objects were found to be radio-loud from recent radio surveys and were marked in the table. When available, the power law photon indices and the corresponding absorption column densities (NH) were estimated from the two hardness ratios given by the SASS, both with free fitted NH and for Galactic absorption. The unabsorbed X-ray flux densities in the ROSAT band (0.1-2.4keV) were calculated from the count rates using the energy to counts conversion factor for power law spectra and Galactic absorption. As the photon index we used the value obtained for the individual source if the estimated 1-σ error is smaller than 0.5, otherwise we used the redshift-dependent mean value (see the paper for details).

On 18 March the new Basic Regulation 216/2008, repealing the original Basic Regulation was published and applicable from 08 April on. The included Essential Requirements extended the competencies of EASA inter alia to Pilot Licensing and Flight Operations. The future aeromedical requirements will be included as Annex II in another Implementing Regulation on Personnel Licensing. The detailed provisions will be published as guidance material. The proposals for these provisions have been published on 05 June 2008 as NPA 2008- 17c. After public consultation, processing of comments and final adoption the new proposals may be applicable form the second half of 2009 on. A transition period of four year will apply. Whereas the provisions are based on Joint Aviation Requirement-Flight Crew Licensing (JAR-FCL) 3, a new Light Aircraft Pilot Licence (LAPL) project and the details of the associated medical certification regarding general practitioners will be something new in aviation medicine. This paper consists of 6 sections. The introduction outlines the idea of international aviation safety. The second section describes the development of the Joint Aviation Authorities (JAA), the first step to common rules for aviation safety in Europe. The third section encompasses a major change as next step: the foundation of the European Aviation Safety Agency (EASA) and the development of its rules. In the following section provides an outline of the new medical requirements. Section five emphasizes the new concept of a Leisure Pilot Licence. The last section gives an outlook on ongoing rulemaking activities and the opportunities of the public to participate in them.

    Résumé Les familles des militaires font face à de nombreux facteurs de stress, tels que les réinstallations fréquentes, les longues pério des de séparation familiale, l’isolement géographique du réseau de soutien de la famille élargie et le déploiement en zones très dangereuses. Les enfants et les adolescents des familles des militaires vivent les mêmes trajectoires développementales et motivationnelles que leurs homologues civils, mais ils sont également aux prises avec des pressions et des facteurs de stress liés à leur développement qui sont inhabituels et qui leur sont imposés par les exigences de la vie militaire. Les effets de la vie militaire sur les familles et les enfants commencent à être admis et mieux caractérisés. Il est essentiel de comprendre les préoccupations propres aux enfants et aux adolescents des familles des militaires et de mobiliser les ressources nécessaires pour les soutenir afin de répondre à leurs besoins en matière de santé.

  8. Étude théorique et expérimentale du transfert du dioctyl phtalate à partir d'un disque de PVC plastifié plongé dans une huile comestible

    When polymer and liquid are contacted with each other, as in packaging, some mass exchanges may occur, which constitute a major drawback when the liquid is a foodstuff or blood. However, these mass transfers in the polymers can appear as very interesting from the industrial point of view, if one is able to use and control them. It is then necessary to have a good knowledge of these transfer processes which are controlled by diffusion. Dioctyl phthalate (DOP) migration into an edible oil was studied under worst conditions: high plasticization level (50% by weight) and temperature(30 circC). The quantitative analysis of DOP in a such complex liquid medium and in the PVC itself was made easy by the use of the radioactive tracer technique. A simplified mathematical model, obtained by neglecting the oil transport in the PVC, was evaluated. This model based on the research of a finite differences explicit solution allows to reproduce for the DOP, the concentration profiles in the polymer and the kinetics of transfer in the oil, with a P-value ≥ 0.001. La mise en contact polymère-liquide se traduit généralement par des échanges de matière entre les 2 milieux considérés, ce qui constitue un inconvénient majeur lorsque le liquide est un aliment ou le sang. Cependant, ces transferts de matière dans les polymères peuvent apparaître comme très intéressants sur le plan industriel, si l'on est capable de les utiliser et de les contrôler. Il est donc nécessaire d'avoir une bonne connaissance de ces processus de transfert qui sont contrôlés par diffusion. Nous avons étudié la migration du dioctyl phtalate (DOP) dans une huile comestible en nous plaçant dans les conditions les plus défavorables: taux de plastification (50% en poids) et température (30°C) élevés. L'analyse quantitative du DOP dans un milieu liquide aussi complexe et dans le PVC lui- même a été facilitée par l'utilisation de la technique des traceurs radioactifs. Un modèle math

    The molecular observations were carried out in August 2015 with the 10m Atacama Submillimeter Telescope Experiment (ASTE). We used DASH345, a two sideband single-polarization heterodyne receiver, tunable in LO frequency range from 327GHz to 370GHz at observable frequency range from 321GHz to 376GHz. The XF digital spectrometer was set to a bandwidth and spectral resolution of 128MHz and 125KHz, respectively. The spectral velocity resolution was 0.11km/s, the half power beamwidth (HPBW) is ~22", and the main beam efficiency (mb) is 0.65. Observations were made using the on-the-fly (OTF) mode with two orthogonal scan directions along RA and Dec. (J2000) centered on RA, Dec.(J2000)= (18:17:02.1, -18:40:19). We observed simultaneously the lines CO(3-2) (345.796GHz) and HCO+(4-3) (356.734) in a region of ~17'x17' (see Fig. 1). The spectra were reduced with NOSTAR2 using the standard procedure. The brightest star projected at the center of [BDS2003] 6 (2MASS J18165113-1841488) was observed on August 2016 with Astronomy Research using the Cornell Infra Red Imaging Spectrograph (ARCoIRIS), a cross-dispersed, single-object, longslit, infrared imaging spectrograph,mounted on Blanco 4-m Telescope, CTIO. The spectra cover a simultaneous wavelength range of 0.80 to 2.47um, at a spectral resolution of about 3500 λ{δλ, encompassing the entire zYJHK photometric range. The spectrum was taken with 480 sec integration time, at 1.03 average airmass. The HD163336 telluric A0 V standard is observed immediately after target. The basic steps of the reduction procedure are described in Chene et al. (2012A&A...545A..54C, Cat. J/A+A/545/A54, 2013A&A...549A..98C). We used the corresponding pipeline. (3 data files).

  10. A Study to Estimate the Effectiveness of Visual Testing Training for Aviation Maintenance Management

    NASA Technical Reports Server (NTRS)

    Law, Lewis Lyle

    2007-01-01

    The Air Commerce Act of 1926 set the beginning for standards in aviation maintenance. Even after deregulation in the late l970s, maintenance standards and requirements still have not changed far from their initial criteria. After a potential candidate completes Federal Aviation Administration training prerequisites, they may test for their Airframe and Powerplant (A&P) certificate. Performing maintenance in the aviation industry for a minimum of three years, the technician may then test for their Inspection Authorization (IA). After receiving their Airframe and Powerplant certificate, a technician is said to have a license to perform. At no time within the three years to eligibility for Inspection Authorization are they required to attend higher-level inspection training. What a technician learns in the aviation maintenance industry is handed down from a seasoned technician to the new hire or is developed from lessons learned on the job. Only in Europe has the Joint Aviation Authorities (JAA) required higher-level training for their aviation maintenance technicians in order to control maintenance related accidents (Lu, 2005). Throughout the 1990s both the General Accounting Office (GAO) and the National Transportation Safety Board (NTSB) made public that the FAA is historically understaffed (GAO, 1996). In a safety recommendation the NTSB stated "The Safety Board continues to lack confidence in the FAA's commitment to provide effective quality assurance and safety oversight of the ATC system (NTSB, 1990)." The Federal Aviation Administration (FAA) has been known to be proactive in creating safer skies. With such reports you would suspect the FAA to also be proactive in developing more stringent inspection training for aviation maintenance technicians. The purpose of this study is to estimate the effectiveness of higher-level inspection training, such as Visual Testing (VT) for aviation maintenance technicians, to improve the safety of aircraft and to make

    Meyer, G.

    2003-02-01

    Quand les neutrons traversent la matière, certains sont transmis sans interaction, les autres interagissent avec le milieu traversé par diffusion et par absorption. Ce phénomène d'absorption est utilisé pour se protéger des neutrons, mais aussi pour les détecter; il peut également être utilisé pour identifier les noyaux “absorbants" et ainsi analyser le milieu traversé. En effet par différentes réactions nucléaires (n,γ), (n,p), (n,α), (n,fission), on obtient des noyaux résiduels qui sont souvent radioactifs; on dit que l'échantillon est “activé". Si l'on connaît le rendement d'activation et donc le pourcentage de noyaux ainsi “transmutés", les mesures de radioactivité induite vont permettre de déterminer la composition de l'échantillon irradié. Cette méthode dite d'analyse par activation neutronique est pratiquée depuis la découverte du neutron. Elle a permis grâce à sa sélectivité et à sa sensibilité d'avoir accès au domaine des traces et des ultra-traces dans des champs d'application très divers comme la métallurgie, l'archéologie, la biologie, la géochimie etc...

    Le syndrome d'Ekbom, ou délire d'infestation parasitaire, est une pathologie rare, caractérisée par la conviction inébranlable d'avoir une peau infestée d'insectes ou de parasites. Il s'agit d'un délire monothématique à mécanisme hallucinatoire qui touche typiquement les femmes d’âge avancé. Nous rapportons les cas de trois patients qui présentent un délire d'infestation parasitaire dans des contextes cliniques différents. Le premier patient souffre d'un délire d'infestation isolé correspondant à la forme décrite par Karl Ekbom. Le deuxième cas présente un délire d'infestation secondaire, s'inscrivant dans le cadre d'une leuco-encéphalopathie de type CADASIL. Enfin, le troisième patient se présente dans un tableau évocateur d'un épisode dépressif avec une caractéristique psychotique qui intègre le délire d'infestation. Ces trois vignettes cliniques illustrent parfaitement le caractère trans-nosographique de ce syndrome ainsi que les difficultés de prise en charge de ces patients, tant au niveau de l'alliance thérapeutique que sur le plan des choix en matière de traitement pharmacologiques.

    L'exobiologie est une jeune science, très pluridisciplinaire qui, de façon générale, a pour objet l'étude de la vie dans l'univers. Plus précisément, elle inclut l'étude des conditions et des processus qui ont permis l'émergence du vivant sur notre planète, et ont pu oumo pourraient le permettre ailleurs, l'étude de l'évolution de la matière organique vers des structures complexes dans l'univers, et les recherches qui concernent la distribution de la vie sous toutes les formes qu'elle pourrait revêtir, et son évolution. La Société Française d'Exobiologie a été fondée en mai 2009. Elle a pour buts principaux de fédérer les recherches en exobiologie au niveau français en facilitant l'établissement de contacts interdisciplinaires entre les chercheurs français et faire connaître et expliquer l'exobiologie pour satisfaire la demande socio culturelle provenant d'un public diversifié, par le biais de conférences, d'ateliers, d'expositions. La SFE est reconnue comme Société savante. Elle compte actuellement 140 membres et vient d'organiser son premier colloque national d'exobiologie à Biarritz.

    Patients with an implantable cardioverter defibrillator (ICD) may experience loss of consciousness. Electromagnetic interference (EMI) may trigger undesired or inhibit necessary therapy in patients with an ICD. Therefore, questions about personal or professional activities for ICD patients arise. Restricting driving or other personal activities has adverse effects on the patient's quality of life. The national Societies of Cardiology provide recommendations for ICD patients concerning driving of motor vehicles. Patients with an ICD that is implanted prophylactically do not have to refrain from driving after recovery from the implantation procedure. Patients with arrhythmias are classified into different groups depending on the risk of recurrence of tachycardias and symptoms. Commercial driving is not allowed for patients with an ICD in Germany except for those with a prophylactic indication without a history of arrhythmias. Those patients may drive small cars but no trucks or busses. Guidelines for medical fitness in commercial or military flying are regulated by the Joint Aviation Authorities (JAA) and ventricular tachycardias are a contraindication for both. Fortunately, loss of consciousness is not dangerous in most jobs. Strong sources of EMI can occur at special workplaces. Patients have to be advised and tested individually concerning their risk for EMI at their employment site before returning safely. Modern life exposes to an increasing amount of EMI. Intact household devices usually do not interfere with ICDs. Mobile phones may interfere with implanted devices. Interaction can be minimized by special precautions like maintaining a distance of minimum 10 cm between mobile phone and ICD. Electronic surveillance systems work differently and have the potential to interact with devices. Patients should be advised to pass those systems with avoiding longer exposure. The presence of an ICD is presently a contraindication for undergoing magnetic resonance imaging

    Key comparison CCQM K-28 was undertaken to assess the measurement capabilities for quantitation of (C4H9)3Sn+ (TBT) in a prepared marine sediment by National Metrology Institutes (NMIs), which are members of the Comité Consultatif pour la Quantité de Matière (CCQM). It follows a previous pilot study, CCQM-P18. [1, 2] This exercise was sanctioned by the 8th CCQM meeting, 18-19 April 2002, as an activity of the Inorganic Analysis Working Group and was jointly coordinated by the Institute for National Measurement Standards of the National Research Council of Canada (NRC) and LGC, UK. Eight NMIs initially indicated their interest, with seven ultimately submitting their results. All NMIs relied on isotope dilution mass spectrometry using a species-specific 117Sn-enriched TBT standard, which was supplied by LGC. No analytical methodology was prescribed for this study. As a result, a variety of extraction approaches was adopted by the participants, including mechanical shaking, sonication, accelerated solvent extraction, microwave assisted extraction and heating in combination with ethylation and direct sampling. Detection techniques included ICP-MS (coupled to GC or HPLC for the separation of Sn species) and GC-MS. Main text. To reach the main text of this paper, click on Final Report.

The study provides support for the following measurement claim: "Quantitation of a linearised plasmid DNA, based on a matched standard in a matrix of non-target DNA". The comparison was an activity of the Bioanalysis Working Group (BAWG) of the Comité Consultatif pour la Quantité de Matière and was coordinated by NIST (Gaithersburg, USA) and LGC (Teddington, UK). The following laboratories (in alphabetical order) participated in this key comparison. DMSC (Thailand); IRMM (European Union); KRISS (Republic of Korea); LGC (UK); NIM (China); NIST (USA); NMIA (Australia); NMIJ (Japan); VNIIM (Russian Federation) Good agreement was observed between the reported results of all nine of the participants. Uncertainty estimates did not account fully for the dispersion of results even after allowance for possible inhomogeneity in calibration materials. Preliminary studies suggest that the effects of fluorescence threshold setting might contribute to the excess dispersion, and further study of this topic is suggested Main text.

    normal polarity (69 - 80 m) was found. Above that, after a small gap of magnetically disturbed sediments, there are 60 meters of sediments with reverse polarity (62 - 2 m) with short normal excursion at the upper half (24 - 17 m). According to the detailed analysis of drill core HK591 (Matys Grygar et al. 2014), we suppose, that the succession begins in C5En (only JP-585-10), then C5Dr. Validity of subzone C5Dr.1n in the drills JP-585-10 and DP-333-09 is still under discussion. The zone C5Cr could be found only in the HD-50 core. In comparison of the interpreted polarities with ATNTS2012 the time span in the studied cores is approximately 17.5 to 17.9 Ma for DP-333-09, 17.8 to 18.1 for JP-585-[2]10 and 17.1 to 17.7 Ma for HD-50.

    Under the Comité Consultatif pour la Quantité de Matière (CCQM), a key comparison, CCQM-K104, was coordinated by the National Institute of Metrology (NIM). The comparison was designed to demonstrate a laboratory's performance in determining the mass fraction of the main component in a complex high purity organic material. Nine NMIs or DIs participated in the comparison. Eight participants reported their results. An additional impurity was resolved from the avermectin B1a peak and was tentatively identified as an unknown impurity by NMIA (National Measurement Institute (Australia)). It was subsequently identified by NIM as a diastereoisomer of avermectin B1a at the C-26 position. Final reference value (KCRV) = 924.63 mg/g, with uncertainty (k=1) = 3.89 mg/g, and expanded uncertainty = 8.97 mg/g. The degrees of equivalence with the avermectin B1a KCRV for each participant were reported. The measurement results and degrees of equivalence should be indicative of the performance of a laboratory's measurement capability for the purity assignment of organic compounds of high structural complexity (relative molecular mass range of 500 Da -1000 Da and low polarity (-log KOW <= -2).

  5. Can shale safely host US nuclear waste?

    "Even as cleanup efforts after Japan’s Fukushima disaster offer a stark reminder of the spent nuclear fuel (SNF) stored at nuclear plants worldwide, the decision in 2009 to scrap Yucca Mountain as a permanent disposal site has dimmed hope for a repository for SNF and other high-level nuclear waste (HLW) in the United States anytime soon. About 70,000 metric tons of SNF are now in pool or dry cask storage at 75 sites across the United States [Government Accountability Office, 2012], and uncertainty about its fate is hobbling future development of nuclear power, increasing costs for utilities, and creating a liability for American taxpayers [Blue Ribbon Commission on America’s Nuclear Future, 2012].However, abandoning Yucca Mountain could also result in broadening geologic options for hosting America’s nuclear waste. Shales and other argillaceous formations (mudrocks, clays, and similar clay-rich media) have been absent from the U.S. repository program. In contrast, France, Switzerland, and Belgium are now planning repositories in argillaceous formations after extensive research in underground laboratories on the safety and feasibility of such an approach [Blue Ribbon Commission on America’s Nuclear Future, 2012; Nationale Genossenschaft für die Lagerung radioaktiver Abfälle (NAGRA), 2010; Organisme national des déchets radioactifs et des matières fissiles enrichies, 2011]. Other nations, notably Japan, Canada, and the United Kingdom, are studying argillaceous formations or may consider them in their siting programs [Japan Atomic Energy Agency, 2012; Nuclear Waste Management Organization (NWMO), (2011a); Powell et al., 2010]."

    Le quatrième colloque Rayons X et Matière (RX 2001) s'est tenu à Strasbourg du 4 au 7 décembre 2001. Comme lors des colloques précédents (1995, 1997 et 1999) nous avons pu réunir de nombreux chercheurs, industriels et constructeurs concernés par la caractérisation des matériaux. Cette manifestation qui se déroule tous les deux ans a pour objectifs de rendre compte périodiquement des avancées faites dans le domaine des techniques X et plus particulièrement de l'ingénierie des surfaces. Cette année nous avons ajouté deux nouveaux thèmes : étude des nanomatériaux et techniques des microfaisceaux. André GUINIER était avec nous lors du premier colloque (colloque 1995, consacré à la commémoration du centenaire de la découverte des rayons X). Nous sommes attristés par son décès et nous lui dédions le Colloque RX 2001. Les premiers articles de cet ouvrage rappellent sa vie de scientifique et ses principaux travaux. En même temps que nous écrivons ces quelques lignes, nous nous préparons à lancer le colloque RX 2003. Ces colloques ont lieu grâce à la participation constante des chercheurs et l'engagement des constructeurs et distributeurs de matériels ; nous les en remercions vivement et nous leur donnons rendez-vous à Strasbourg, en décembre 2003.

    The NOrthern ROSAT All-Sky (NORAS) galaxy cluster survey project is based on the ROSAT All-Sky Survey (RASS; Trumper 1993Sci...260.1769T), which is the only full-sky survey conducted with an imaging X-ray telescope. We have already used RASS for the construction of the cluster catalogs of the NORAS I project. While NORAS I was as a first step focused on the identification of galaxy clusters among the RASS X-ray sources showing a significant extent, the complementary REFLEX I sample in the southern sky was strictly constructed as a flux-limited cluster sample. A major extension of the REFLEX I sample, which roughly doubles the number of clusters, REFLEX II (Bohringer et al. 2013, Cat. J/A+A/555/A30), was recently completed. It is by far the largest high-quality sample of X-ray-selected galaxy clusters. The NORAS II survey now reaches a flux limit of 1.8*10-12erg/s/cm2 in the 0.1-2.4keV band. Redshifts have been obtained for all of the 860 clusters in the NORAS II catalog, except for 25 clusters for which observing campaigns are scheduled. Thus with 3% missing redshifts we can already obtain a very good view of the properties of the NORAS II cluster sample and obtain some first results. The NORAS II survey covers the sky region north of the equator outside the band of the Milky Way (|bII|>=20°). We also excise a region around the nearby Virgo cluster of galaxies that extends over several degrees on the sky, where the detection of background clusters is hampered by bright X-ray emission. This region is bounded in right ascension by R.A.=185°-191.25° and in declination by decl.=6°-15° (an area of ~53deg2). With this excision, the survey area covers 4.18 steradian (13519deg2, a fraction of 32.7% of the sky). NORAS II is based on the RASS product RASS III (Voges et al. 1999, Cat. IX/10), which was also used for REFLEX II. The NORAS II survey was constructed in a way identical to REFLEX II with a nominal flux limit of 1.8*10-12erg/s/cm2. (3 data files).

    Nous présentons I 'état du Modèle Standard des interactions fortes, faibles et électromagnétiques. Après une description rapide de ses 3 secteurs, secteur de jauge (radiation), secteur fermionique (matière) et secteur scalaire (génération des masses), nous insistons sur le grand nombre de paramètres libres et sur les choix arbitraires qu'il a fallu faire dans l'élaboration du modèle. Nous faisons ressortir les problèmes techniques non résolus et nous dressons la liste des questions fondamentales restées sans réponses. Nous passons ensuite en revue les idées et méthodes proposées pour répondre à ces questions. Elles utilisent essentiellement 3 voies différentes. La première consiste à requérir plus de symétrie (extension du modèle, symétrie Gauche-Droite, Grandes Unifications, Supersymétrie,...). La seconde contient les diverses alternatives au Modèle Standard impliquant des modifications dans certains secteurs (par exemple le secteur scalaire avec le modèle de la Technicouleur) ou de façon plus violente l'hypothèse d'une sous-structure des leptons, des quarks et des bosons W et Z eux-mêmes. Une dernière voie cherche à justifier les particularités du Modèle Standard et relier ses paramètres libres en se basant sur des principes de cohérence interne du modèle. Les conséquences observables de ces diverses approches sont dans chaque cas mentionnées.

    En usinage par enlèvement de copeaux, il est nécessaire de connaître des éléments tels que la géométrie à obtenir, la matière à usiner, le type d'opération, la machine-outil, l'outil de coupe, la profondeur de passe, l'avance, la vitesse de coupe. Ces trois derniers éléments quantifiables sont déterminés à l'aide de tables, abaques, logiciel informatique dédié, ou système CFAO, offrant une large gamme de choix mais manquant de transparence et de flexibilité. La contribution de cet article est d'appliquer les techniques d'intelligence artificielle basées sur les réseaux de neurones artificiels (RNA) au développement d'un système de décision pour le choix des paramètres de coupe. Pour modéliser la vitesse de coupe, nous utilisons un RNA avec un algorithme de rétro-propagation. Des valeurs expérimentales provenant d'un abaque source serviront à construire et établir le RNA pour estimer la valeur de la vitesse de coupe, utilisant comme données un certain nombre de paramètres d'influence. La validité des résultats obtenus montre que cette méthode peut être appliquée avec succès et que son utilisation dans le domaine de l'usinage peut contribuer à optimiser les conditions de coupe par un choix plus précis et plus rapide de la vitesse de coupe.

    Key comparison CCQM-K86 was performed to demonstrate and document the capacity of interested national metrology institutes (NMIs) and designated institutes (DIs) in the determination of the relative quantity of two specific genomic DNA fragments present in a biological tissue. The study provides the support for the following measurement claim: "Quantification of the ratio of the number of copies of specified intact sequence fragments of a length in the range of 70 to 100 nucleotides in a single genomic DNA extract from ground maize seed materials". The study was carried out under the auspices of the Bioanalysis Working Group (BAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM) and was piloted by the Institute for Reference Materials and Methods (IRMM) in Geel (Belgium). The following laboratories (in alphabetical order) participated in this key comparison: AIST (Japan), CENAM (Mexico), DMSc (Thailand), GLHK (Hong Kong), IRMM (European Union), KRISS (Republic of Korea), LGC (United Kingdom), MIRS/NIB (Slovenia), NIM (PR China), NIST (USA), NMIA (Australia), TÜBITAK UME (Turkey) and VNIIM (Russian Federation).

    Under the Comité Consultatif pour la Quantité de Matière (CCQM), a key comparison, CCQM-K103, was coordinated by the National Institute of Metrology (NIM) and Government Laboratory, Hong Kong, China (GLHK). The comparison was designed to demonstrate NMIs/DIs ability to analyze traces of melamine in milk and milk powder at concentration levels resulting from requirements for food safety. Seven NMIs or DIs participated in the comparison. Final reference value (KCRV) is 0.286 mg/kg, with standard uncertainty of the median as 0.011 mg/kg (3.8 %). The k-factor for the estimation of the expanded uncertainty was chosen as k = 2.57 ( t (0.05;5) ), thus the expanded uncertainty is 0.028 mg/kg (9.8%). The degrees of equivalence with melamine in milk powder KCRV for each participant were reported. The measurement results and degrees of equivalence should be indicative of the performance of a laboratory's measurement capability for IDMS in determining mass fractions in the range from 0.1 to 5.0 mg/kg of analytes with low molar mass (range 50-300 Da) with high polarity (pKow > -2.0) in milk and milk products. Extension to other analytes and matrices should be applied with care since there is a close linkage to other relevant parameters as e.g. sample preparation procedures (liquid/liquid extraction, SPE clean-up) and analytical separation techniques (e.g., GC-MS, LC-MS/MS etc).

    The outburst of the recurrent nova V745 Sco (Nova Sco 1937) by Rod Stubbings (Tetoora Road, VIC, Australia) at visual magnitude 9.0 on 2014 February 6.694 UT is reported. This recurrent nova is fading quickly. Follow-up observations of all types (visual, CCD, DSLR) are strongly encouraged, as is spectroscopy; fast time-series of this nova may be useful to detect possible flaring activity as was observed during the outburst of U Scorpii in 2010. Coincident time-series by multiple observers would be most useful for such a study, with a V-filter being preferred. Observations reported to the AAVSO International Database show V745 Sco at visual mag. 10.2 on 2014 Feb. 07.85833 UT (A. Pearce, Nedlands, W. Australia). Finder charts with sequence may be created using the AAVSO Variable Star Plotter (http://www.aavso.org/vsp). Observations should be submitted to the AAVSO International Database. Previous outbursts occurred in 1937 and 1989. The 1937 outburst was detected in 1958 (in decline at magnitude 11.0 on 1937 May 11.1 UT; outburst had occurred within the previous 19 days) by Lukas Plaut on plates taken by Hendrik van Gent at the Leiden Observatory; the object was announced as Nova Sco 1937 and later assigned the GCVS name V745 Sco. The 1989 outburst was detected on 1989 August 1.55 UT by Mati Morel (MMAT, Thornton, NSW, Australia) at visual magnitude 10.4 and in decline. Dr. Bradley Schaefer (Louisiana State University) reports (2010ApJS..187..275S) in his comprehensive analysis of the 10 known galactic recurrent novae (including V745 Sco) that the median interval between recurrent novae outbursts is 24 years. The interval since the 1989 outburst of V745 Sco is 24.10 years. See the Alert Notice for additional visual and multicolor photometry and for more details.

    Shields, used for protection against radiation, are often pierced with vacuum channels for passing cables and other instruments for measurements. The neutron transmission through these shields is an unavoidable phenomenon. In this work we study and discuss the effect of channels on neutron transmission through shields. We consider an infinite homogeneous slab, with a fixed thickness (20 lambda, with lambda the mean free path of the neutron in the slab), which contains a vacuum channel. This slab is irradiated with an infinite source of neutrons on the left side and on the other side (right side) many detectors with windows equal to 2 lambda are placed in order to evaluate the neutron transmission probabilities (Khanouchi, A., Aboubekr, A., Ghassoun, J. and Jehouani, A. (1994) Rencontre Nationale des Jeunes Chercheurs en Physique. Casa Blanca Maroc; Khanouchi, A., Sabir, A., Ghassoun, J. and Jehouani, A. (1995) Premier Congré International des Intéractions Rayonnements Matière. Eljadida Maroc). The neutron history within the slab is simulated by the Monte Carlo method (Booth, T. E. and Hendricks, J. S. (1994) Nuclear Technology 5) and using the exponential biasing technique in order to improve the Monte Carlo calculation (Levitt, L. B. (1968) Nuclear Science and Engineering 31, 500-504; Jehouani, A., Ghassoun, J. and Aboubker, A. (1994) In Proceedings of the 6th International Symposium on Radiation Physics, Rabat, Morocco). Then different geometries of the vacuum channel have been studied. For each geometry we have determined the detector response and calculated the neutron transmission probability for different detector positions. This neutron transmission probability presents a peak for the detectors placed in front of the vacuum channel. This study allowed us to clearly identify the neutron channeling phenomenon. One application of our study is to detect vacuum defects in materials.

    Introduction Afin d’évaluer une grille de contrôle standardisée de laboratoire de diagnostic des leishmanioses, comme nouveau outil de supervision. Méthodes Un essai pilote a été pratiqué sur sept laboratoires provinciaux, appartenant à quatre provinces au Maroc, en suivant l’évolution de leurs performances tous les deux ans, entre l’année 2006 et 2014. Cette étude détaille la situation des laboratoires provinciaux avant et après la mise en œuvre de la grille de supervision. Au total vingt et une grille sont analysées. Résultats En 2006, les résultats ont montré clairement une insuffisance des performances des laboratoires: besoin en formation (41.6%), personnel pratiquant le prélèvement cutané (25%), pénurie en matériels et réactifs (65%), gestions documentaire et local non conformes (85%). Différentes actions correctives ont été menées par le Laboratoire National de Référence des Leishmanioses (LNRL) durant la période d’étude. En 2014, le LNRL a enregistré une nette amélioration des performances des laboratoires. Les besoins en matière de formation, qualité du prélèvement, dotation en matériels et réactifs ont été comblés et une coordination efficace s’est établie entre le LNRL et les laboratoires provinciaux. Conclusion Ceci montre l'efficacité de la grille comme outil de supervision de grande qualité, et comme pierre angulaire de tout progrès qui doit être obtenu dans les programmes de lutte contre les leishmanioses.

    The stochastic versions of the logistic and extended logistic growth models are applied successfully to explain many real-life population dynamics and share a central body of literature in stochastic modeling of ecological systems. To understand the randomness in the population dynamics of the underlying processes completely, it is important to have a clear idea about the quasi-equilibrium distribution and its moments. Bartlett et al. (1960) took a pioneering attempt for estimating the moments of the quasi-equilibrium distribution of the stochastic logistic model. Matis and Kiffe (1996) obtain a set of more accurate and elegant approximations for the mean, variance and skewness of the quasi-equilibrium distribution of the same model using cumulant truncation method. The method is extended for stochastic power law logistic family by the same and several other authors (Nasell, 2003; Singh and Hespanha, 2007). Cumulant truncation and some alternative methods e.g. saddle point approximation, derivative matching approach can be applied if the powers involved in the extended logistic set up are integers, although plenty of evidence is available for non-integer powers in many practical situations (Sibly et al., 2005). In this paper, we develop a set of new approximations for mean, variance and skewness of the quasi-equilibrium distribution under more general family of growth curves, which is applicable for both integer and non-integer powers. The deterministic counterpart of this family of models captures both monotonic and non-monotonic behavior of the per capita growth rate, of which theta-logistic is a special case. The approximations accurately estimate the first three order moments of the quasi-equilibrium distribution. The proposed method is illustrated with simulated data and real data from global population dynamics database. Copyright © 2015 Elsevier Inc. All rights reserved.

  18. Evaluation of the combined measurement uncertainty in isotope dilution by MC-ICP-MS.

    The combination of metrological weighing, the measurement of isotope amount ratios by a multicollector inductively coupled plasma mass spectrometer (MC-ICP-MS) and the use of high-purity reference materials are the cornerstones to achieve improved results for the amount content of lead in wine by the reversed isotope dilution technique. Isotope dilution mass spectrometry (IDMS) and reversed IDMS have the potential to be a so-called primary method, with which close comparability and well-stated combined measurement uncertainties can be obtained. This work describes the detailed uncertainty budget determination using the ISO-GUM approach. The traces of lead in wine were separated from the matrix by ion exchange chromatography after HNO(3)/H(2)O(2) microwave digestion. The thallium isotope amount ratio ( n((205)Tl)/ n((203)Tl)) was used to correct for mass discrimination using an exponential model approach. The corrected lead isotope amount ratio n((206)Pb)/ n((208)Pb) for the isotopic standard SRM 981 measured in our laboratory was compared with ratio values considered to be the least uncertain. The result has been compared in a so-called pilot study "lead in wine" organised by the CCQM (Comité Consultatif pour la Quantité de Matière, BIPM, Paris; the highest measurement authority for analytical chemical measurements). The result for the lead amount content k(Pb) and the corresponding expanded uncertainty U given by our laboratory was:k(Pb)=1.329 x 10-10mol g-1 (amount content of lead in wine)U[k(Pb)]=1.0 x 10-12mol g-1 (expanded uncertainty U=kxuc, k=2)The uncertainty of the main influence parameter of the combined measurement uncertainty was determined to be the isotope amount ratio R(206,B) of the blend between the enriched spike and the sample.

    RÉSUMÉ Une population vieillissante et la croissance de la population sur la base de l'immigration nécessitent que la recherche, la pratique et la politique doivent se concentrer sur la santé mentale des immigrants âgés, surtout parce que leur santé mentale semble se détériorer au fil du temps. Cette revue se concentre sur: Qu'est-ce que l'on sait sur les déterminants sociaux de la santé mentale chez les immigrants âgés, et quels sont les obstacles à l'accès aux services de santé mentale confrontés par les immigrants âgés? Les résultats révèlent que (1) les déterminants sociaux décisifs de la santé mentale sont la culture, le sexe et les services de santé; (2) que les immigrants plus âgés utilisent les services de santé mentale de moins que leurs homologues nés au Canada à cause des obstacles tels que, par exemple, les croyances et les valeurs culturelles, un manque de services culturellement et linguistiquement appropriées, des difficultés financières, et l'âgisme; et (3) quelles que soient les sous-catégories dans cette population, les immigrants âgés éprouvent des inégalités en matière de la santé mentale. La preuve des recherches disponibles indique que de combler les lacunes des service de santé mentale devrait devenir une priorité pour la politique et la pratique du système de soins de santé au Canada.

    Engine failure represents a major safety concern to helicopter operations, especially in the critical flight phases of takeoff and landing from/to small, confined areas. As a result, the JAA and FAA both certificate a transport helicopter as either Category-A or Category-B according to the ability to continue its operations following engine failures. A Category-B helicopter must be able to land safely in the event of one or all engine failures. There is no requirement, however, for continued flight capability. In contrast, Category-A certification, which applies to multi-engine transport helicopters with independent engine systems, requires that they continue the flight with one engine inoperative (OEI). These stringent requirements, while permitting its operations from rooftops and oil rigs and flight to areas where no emergency landing sites are available, restrict the payload of a Category-A transport helicopter to a value safe for continued flight as well as for landing with one engine inoperative. The current certification process involves extensive flight tests, which are potentially dangerous, costly, and time consuming. These tests require the pilot to simulate engine failures at increasingly critical conditions, Flight manuals based on these tests tend to provide very conservative recommendations with regard to maximum takeoff weight or required runway length. There are very few theoretical studies on this subject to identify the fundamental parameters and tradeoff factors involved. Furthermore, a capability for real-time generation of OEI optimal trajectories is very desirable for providing timely cockpit display guidance to assist the pilot in reducing his workload and to increase safety in a consistent and reliable manner. A joint research program involving NASA Ames Research Center, the FAA, and the University of Minnesota is being conducted to determine OEI optimal control strategies and the associated optimal,trajectories for continued takeoff (CTO

    Our sample consists of the 92 Young Stellar Objects (YSOs) in σ Orionis with infrared excesses consistent with the presence of a protoplanetary disk. hese sources are identified by cross-matching the Class II and transition disk (TD) candidates from the Spitzer survey of Hernandez et al. 2007 (Cat. J/ApJ/662/1067) with the Mayrit catalog (Caballero 2008, Cat. J/A+A/478/667). Both catalogs are expected to be complete down to the brown dwarf limit. Disk classifications are based on the Spitzer/Infrared Array Camera (IRAC) Spectral Energy Distribution (SED) slope, as described in Hernandez et al. 2007 (Cat. J/ApJ/662/1067). We also include in our sample a Class I disk (source 1153), as it is located near the Spitzer/IRAC color cutoff for Class II disks. Our Band 6 Atacama Large Millimeter/sub-millimeter Array (ALMA) observations were obtained on 2016 July 30 and 31 during Cycle 3 (Project ID: 2015.1.00089.S; PI: Williams). The array configuration used 36 and 37 12m antennas on July 30 and 31, respectively, with baselines of 15-1124m on both runs. The correlator setup included two broadband continuum windows centered on 234.293 and 216.484GHz with bandwidths of 2.000 and 1.875GHz and channel widths of 15.625 and 0.976MHz, respectively. The bandwidth-weighted mean continuum frequency was 225.676GHz (1.33mm). The spectral windows covered the 12CO (230.538GHz), 13CO (220.399GHz), and C18O (219.560GHz) J=2-1 transitions at velocity resolutions of 0.16-0.17km/s. These spectral windows were centered on 230.531, 220.392, and 219.554GHz with bandwidths of 11.719MHz and channel widths of 0.122MHz. On-source integration times were 1.2 minutes per object for an average continuum rms of 0.15mJy/beam (Table1). This sensitivity was based on the James Clerk Maxwell Telescope (JCMT)/Submillimeter Common User Bolometer Array (SCUBA)-2 survey of σ Orionis disks by Williams et al. 2013 (Cat. J/MNRAS/435/1671), who found that stacking their individual non-detections revealed a mean 850

    Introduction Les plantes constituent une grande source de principes actifs qui peuvent être utilisés pour traiter de nombreuses maladies, dont le diabète. L'objectif de cette étude était de recenser les plantes utilisées en médecine traditionnelle pour traiter le diabète dans la région Maritime du Togo. Méthodes De janvier 2013 à juin 2014, une enquête ethnobotanique a été réalisée auprès de 164 guérisseurs traditionnels dans la région Maritime par des interviews directes à l'aide d'un questionnaire semi structuré. Résultats Les données recueillies ont permis d'identifier 112 espèces végétales appartenant à 51 familles. Les familles les plus représentées ont été les Caesalpiniaceae / Fabaceae avec 9 espèces, suivie des Euphorbiaceae et des Compositae avec 8 espèces chacune. Les espèces les plus citées ont été Allium sativum, Alium cepa, Guilandina bonduc, Moringa oleifera et de Picralima nitida qui ont eu une valeur usuelle de 0,05. En termes de recettes, 132 recettes sont préparées à partir des 112 espèces de plantes. Les recettes à plantes uniques ont été au nombre de 78, tandis que 54 recettes sont obtenues par des associations de plantes. Les parties de plantes les plus utilisées ont été les feuilles suivies par les racines. La principale méthode de préparation reste la décoction. Conclusion La région maritime du Togo dispose d'une biodiversité floristique importante en matière de plantes antidiabétiques. Ces résultats constituent une bonne base de données pour le criblage biologique dans la recherche de molécules antidiabétiques à base des plantes. PMID:26309469

    Introduction Le cancer du sein représente un problème de santé publique majeur au Maroc. C'est le premier cancer chez la femme. L'objectif de ce travail était d'évaluer les connaissances des médecins généralistes (MG) en matière de dépistage du cancer du sein dans la préfecture de Mohammedia Maroc. Méthodes Nous avons mené une étude transversale, descriptive, exhaustive incluant les 97 MG exerçant dans les établissements de soins de santé de base du secteur public et privé de la province de Mohammedia. Résultats Le taux de participation était de 87%. L'âge moyen des MG était de 49,6 ± 8,1. Quatre-vingt pour cent (n=55) des MG ont donné une incidence incorrecte, 77,6% (n=85) ont reconnu l'existence d'un plan national de prévention et de contrôle du cancer (PNPCC) au Maroc, et 67,1 des MG ont rapporté l'existence d'un registre du cancer au Maroc. Le secteur d'activité était associé significativement avec les connaissances des MG sur le PNPCC et sur l'existence d'un guide de détection précoce du cancer du sein avec respectivement (p=0,003 et p=0,001). Une association significative entre l'ancienneté et l'existence d'un guide de détection précoce du cancer du sein et d'un registre du cancer du sein a été retrouvée avec (respectivement p=0,005 et p=0.002). Conclusion À la lumière de ces résultats il faudra renforcer les connaissances et les pratiques des MG par la promotion de la formation initiale et continue sur le dépistage. PMID:27800098

    Résumé Objectif Répondre aux questions souvent posées sur la prise en charge de la pneumonie en phase terminale, de l’apport nutritionnel insuffisant et de la déshydratation dans les cas de démence avancée. Sources des données Une recherche a été effectuée dans MEDLINE sur Ovid pour des articles pertinents publiés jusqu’en février 2015. Aucune étude de niveau I n’a été relevée; la plupart des articles fournissaient des preuves de niveaux III. Les suggestions en matière de prise en charge des symptômes s’appuient en partie sur une récente participation à une approche Delphi visant à concevoir une directive pour le soulagement optimal des symptômes chez les patients atteints de pneumonie et de démence. Message principal Les sondes d’alimentation ne sont pas recommandés chez les patients atteints de démence terminale. L’alimentation de confort manuelle est préférable. L’hydratation parentérale pourrait être utile, mais elle peut aussi contribuer à l’inconfort à la fin de la vie. Si les soins buccaux sont adéquats, l’abstention ou la cessation de l’alimentation et de l’hydratation artificielles ne sont généralement pas associées à des manifestations d’inconfort. Puisque la pneumonie est habituellement très inconfortable, les cliniciens doivent être attentifs à la maîtrise des symptômes. La sédation pour maîtriser l’agitation est souvent utile chez les patients atteints de démence terminale. Conclusion Les soins à visée symptomatique sont une option appropriée pour les manifestations terminales de la démence avancée. Les lignes directrices de prise en charge des symptômes proposées s’appuient sur une revue de la littérature et sur un consensus d’experts.

    Introduction Les maladies cardiovasculaires (MCV) occupent une place importante dans la mortalité en Afrique, situation inquiétante traduisant une transition épidémiologique rapide. La connaissance des groupes nosologiques les plus mortelles devrait aider à l’élaboration de politiques en matière de traitement et de prévention. Méthodes Il's agit d une étude rétrospective du 1er janvier 2006 au 31 décembre 2010, ayant inclus les patients hospitalisés pour une MCV selon la classification Internationale des maladies (CIM-10). Résultats La fréquentation hospitalière pour maladie MCV a augmenté au fil du temps; les maladies hypertensives étaient le premier motif d hospitalisation (66.8%). Les autres pathologies fréquentes étaient la maladie thromboembolique (9.1%), les syndromes coronaires aigus (SCA) (7.3%), l'insuffisance cardiaque (5.5%), les cardiomyopathies (5.3%). La majorité des sujets étaient jeunes (âge moyen: 55.1 ans) et il n'y avait pas de corrélation entre la durée d'hospitalisation et l’âge: r = + 0.024, p = 0.09. La mortalité globale était élevée (11%) et les taux de létalité élevés dans le SCA (27.9%), l'embolie pulmonaire (25%) et la péricardite (25%). Conclusion Les MCV sont responsables d'une hospitalisation croissante dans nos hôpitaux. L'absence d unité de soins intensifs cardiologiques et des méthodes de revascularisation coronaire, le manque de personnels qualifiés associés l'inexistence de sécurité sociale expliquent une mortalité élevée dans nos pays en voie de développement qui sans avoir achevé leur transition démographique entre en pleine transition épidémiologique.

    Shortened slash-and-burn cycles exhaust agricultural land and have resulted in extensive tracts of highly degraded land across the tropics. Land degradation typically results in decreased rainfall infiltration due to a reduced field-saturated hydraulic conductivity of the topsoil because of a progressive decline in soil organic matter, exposure to raindrop impact, surface sealing and compaction. This results, in turn, in enhanced surface runoff and erosion, and consequently less subsurface flow and groundwater recharge. On the other hand, natural vegetation regrowth or active reforestation can lead to a renewed accumulation of soil organic matter, macropore development and increased infiltration rates. As part of the P4GES project (Can Paying 4 Global Ecosystem Services values reduce poverty?; www.p4ges.org), we study the effects of land use change and reforestation on water resources in the Corridor Ankeniheny-Zahamena (CAZ) in eastern Madagascar. In this poster, we present the results of infiltration and preferential flow measurements in four different land uses in the southern part of the CAZ: (i) closed canopy forest, (ii) 3-14 year-old regrowth on fallow land (savokas), (iii) exhausted and severely degraded land (tany maty), and (iv) recently reforested sites (6-8 years old). The results show that infiltrability increases significantly after several years of forest regrowth after land abandonment, but it remains unclear whether active replanting decreases the time required for restoration of soil hydrological functioning. Preferential flow pathways differed strikingly between the respective land cover types: infiltration in mature forests was predominantly characterized by macropore flow (preferential flow pathways), whereas infiltration in exhausted agricultural land was dominated by matrix flow (few preferential flow pathways). Occurrence of preferential flow pathways in reforestation and fallow sites varied considerably. These results suggest that land

    Au Canada, l'amélioration de l'expérience des patients est devenue une priorité des politiques de santé. Le perfectionnement et la normalisation des outils et systèmes pour surveiller les mesures de l'expérience des patients augmentent, tandis que la tendance vers une plus grande reddition de compte sur des améliorations durables et abordables se confirme. Pour de nombreux professionnels de la santé, ce phénomène fait foi d'un intérêt renouvelé pour les besoins et priorités fondamentaux des patients, après des décennies où les changements structurels et technologiques ont dominé les programmes de santé. Pour les leaders en santé canadiens, l'amélioration de l'expérience des patients comporte actuellement de grands défis et de belles possibilités. À cet égard, l'expérience des organisations partenaires du groupe Studer au Canada est à la fois pertinente et instructive. Ces organisations ont adopté un modèle, du nom de Evidence-Based Leadership (EBL, ou leadership fondé sur des données probantes), qui favorise et soutient l'harmonisation de l'ensemble des activités et des comportements, conformément à des objectifs organisationnels précis, y compris des améliorations mesurables de l'expérience des patients. Le présent article expose des études de cas d'organisations qui ont adopté l'EBL. Ces organisations ont réalisé des progrès rapides en matière d'indicateurs de l'expérience des patients, ainsi que dans des secteurs essentiels comme les résultats cliniques, la sécurité et le rendement financier. Les données émergentes sur les facteurs et processus qui sous-tendent ces améliorations sont également abordées. © 2015 Collège canadien des leaders en santé

    Introduction La fistule obstétricale est un orifice entre le vagin et la vessie ou le rectum, voire les deux. Ses impacts sont des conséquences anatomo-fonctionnelles et sociales. On estime à plus de 19 000 le nombre de femmes qui souffrent de fistule obstétricale au Cameroun. Méthodes Il s'agissait d'une étude transversale descriptive conduite dans trois districts de santé de la région de l'Extrême-nord. Vingt-huit femmes victimes de fistules obstétricales, quarante-deux membres de leur entourage et vingt-quatre agents de santé ont été interviewés entre Novembre et Décembre 2013. Trois types de questionnaires ont été utilisés. Les données ont été analysées dans Epi Info version 7.1.4.0. Les moyennes et les fréquences ont été calculées avec un intervalle de confiance à 95%. Résultats 46,4% des femmes victimes de fistule obstétricales interviewées avaient subi une intervention chirurgicale réparatrice parmi lesquelles, 61,5% bénéficiaient de la réintégration. Le fonds de commerce (62,5%) était l'aide la plus reçue. Vingt-deux membres de l'entourage savaient pourquoi on fait la réintégration. Selon eux, les considérations socioculturelles (68,2%), sont la principale barrière de la réintégration. D'après les agents de santé, le suivi psychosocial (58,3%) est la principale activité de la réintégration dans les centres de prise en charge de la fistule. Conclusion La prise en charge des fistules obstétricales au Cameroun souffre de manque de réintégration sociale. Ceci expliquerait en partie la persistance de cette pathologie. Un accent devrait être mis sur l'appui matériel, financier et sur le suivi psychosocial des femmes victimes de fistule obstétricale. PMID:26113915

    The MS and XRF updates have been published together since their introduction in 1988. In the last few years, however, the two sections have been prepared independently of each other and it therefore seemed appropriate to publish the two sections separately. With effect from this issue, the MS Update will appear in the October issue of JAAS and the XRF Update in the November issue. The format used for the MS section is broadly similar to that used last year, with some additional sub-headings. This Update is intended to cover all atomic and stable isotopic MS techniques, but not thosemore » used in studies of fundamental nuclear physics and exotic nuclei far from stability. Also excluded are those reports in which MS is used as a tool in the study of molecular processes and of gaseous components. the review is based on critical selection of developments in instrumentation and methodology, notable for their innovation, originality or achievement of significant advances, and is not intended to be comprehensive in its coverage. Conference papers are only included if they contain enough information to show they meet these criteria, and our policy in general remains one of waiting for a development to appear in a full paper before inclusion in the review. a similar policy applies to foreign language papers unlikely to reach a wide audience. Routine applications of atomic MS are not included in this Update and the reader is referred to the Updates on Industrial Analysis: Metals, Chemicals and Advanced Materials (96/416), Environmental Analysis (96/1444) and Clinical and Biological Materials, Food and Beverages (96/2479). Also excluded are those applications, even if not routine, which use atomic spectroscopy as a tool for the study of a non-atomic property, for example, the use of stable isotope labeling of carbon or nitrogen in biomolecules in metabolic studies.

    Phlebology originated in Paris and Tübingen where Jean Sicard and Paul Linser accidentally discovered the possibility of the sclerotherapy of varicose veins. The second element in the treatment of lymphovenous insufficiency is ambulatory compression described as far back as the 18th century. It is only recently that reasons for its efficiency have been understood, with the study of fibrinolysis (which is counter-thrombotic), in England. The third step was the medical treatment of arterial affections, developed notably by Henri Reboul in Paris, with the aid of intra-arterial injections. In this way non-surgical disorders entered into the realm of phlebology. In 1947 Raymond Tournay, Jean Sicard, Jean Marmasse founded the French Phlebological Association (Société Française de Phlébologie) which went rapidly from strength to strength. Ten years later its counterpart was founded in Benelux (Van der Molen, Van der Stricht, Zoller) and in the Federal Republic of Germany (E. Krieg, F. Jäger, M. Ratschow, P. Matis, U. Ellerbroek, F. Olsen). Today there are phlebological associations throughout Europe, or at least phlebological sections of dermatological associations (Austria, Italy, Scandinavia). Switzerland, too, is very active in the phlebological field (Bolliger, Kappert, Leu). New evaluation devices (such as Sonar-Doppler, plethysmography etc.) improve diagnosis, made even more objective by the use of radiology. There are still too few phlebological teaching centres, and many of the existing ones have a surgical and clinical emphasis, and neglect polyclinical work. Besides the existing Phlebological Associations on other continents (Canada, Australia, South America) the Collège de Pathologie Vasculaire found by Cl. Olivier in Paris is very active. It offers most comprehensive theoretical and practical teaching.

    Les kystes de l'ovaire constituent l'un des motifs les plus fréquents de consultation en gynécologie. L’étape diagnostique repose principalement sur l’échographie. Nous proposons dans ce travail un score échographique reproductible prédictif de malignité. Nous évaluons la fiabilité de ce score après confrontations des données échographiques et histologiques. Il s'agit d'une étude rétrospective réalisée sur une période de 3 ans. Nous avons élaboré un score basé sur les signes échographiques décrits dans la littérature comme prédictifs de malignité et avons classé les examens échographiques préopératoires selon leurs scores respectifs. Les données échographiques étaient comparées aux résultats histologiques et un seuil prédictif de malignité a été déterminé pour le score adopté. 150 patientes ont été colligées. Les deux signes échographiques les plus prédictifs de malignité étaient: les végétations endo-kystiques, avec une Valeur Prédictive Positive (VPP) à 86,67% et une Valeur Prédictive Négative (VPN) à 100%, et le caractère vascularisé au Doppler couleur avec une VPP à 72,52% et une VPN à 100%. Le seuil retenu pour le score proposé était de 6 avec une spécificité de 100%, une sensibilité de 100%, une VPP de 100% et une VPN de 100%. L’échographie joue un rôle décisif dans la conduite à tenir devant une masse ovarienne. Seul un faisceau d'arguments permet d’évoquer la malignité lors de l'examen échographique. L'utilisation de scores basés sur des signes simples, reproductibles augmente la valeur diagnostique de l’échographie en matière de malignité. PMID:25419341

  16. Multi-State Vibronic Interactions in Fluorinated Benzene Radical Cations.

    2009-06-01

    Conical intersections of potential energy surfaces have emerged as paradigms for signalling strong nonadiabatic coupling effects. An important class of systems where some of these effects have been analyzed in the literature, are the benzene and benzenoid cations, where the electronic structure, spectroscopy, and dynamics have received great attention in the literature. In the present work a brief overview is given over our theoretical treatments of multi-mode and multi-state vibronic interactions in the benzene radical cation and some of its fluorinated derivatives. The fluorobenzene derivatives are of systematic interest for at least two different reasons. (1) The reduction of symmetry by incomplete fluorination leads to a disappearance of the Jahn-Teller effect present in the parent cation. (2) A specific, more chemical effect of fluorination consists in the energetic increase of the lowest σ-type electronic states of the radical cations. The multi-mode multi-state vibronic interactions between the five lowest electronic states of the fluorobenzene radical cations are investigated theoretically, based on ab initio electronic structure data, and employing the well-established linear vibronic coupling model, augmented by quadratic coupling terms for the totally symmetric vibrational modes. Low-energy conical intersections, and strong vibronic couplings are found to prevail within the set of tilde{X}-tilde{A} and tilde{B}-tilde{C}-tilde{D} cationic states, while the interactions between these two sets of states are found to be weaker and depend on the particular isomer. This is attributed to the different location of the minima of the various conical intersections occurring in these systems.

    The key comparison CCQM-K126 low polarity organic in water: carbamazepine in surface water was coordinated by Government Laboratory Hong Kong under the auspices of the Organic Analysis Working Group (OAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM). Eight National Metrology institutes or Designated Institutes participated and participants were requested to report the mass fraction of carbamazepine in surface water study material. The surface water sample was collected in Hong Kong and was gravimetrically spiked with standard solution. This study provided the means for assessing measurement capabilities for determination of low molecular weight analytes (mass range 100-500) and low polarity (pKOW<= -2) in aqueous matrix. Nine NMIs/DIs registered for the KC and one withdrew before results were submitted. Nine results were submitted by the eight participants. Eight results applied the LC-MS/MS method and Isotope Dilution Mass Spectrometry approach for quantification. BAM additionally submitted a result from ELISA that was not included in the key comparison reference values (KCRV) calculation as is provided in the report for information. One further result was not included as the participant withdrew their result from the calculation after further analysis. The assigned KCRV was the median of the seven results and was assigned a KCRV of 250.2 ng/kg with a combined standard uncertainty of 3.6 ng/kg, The k-factor for the estimation of the expanded uncertainty of the KCRVs was chosen as k = 2. The degree of equivalence (with the KCRV) and its uncertainty was calculated for each result. Seven of the participants were able to demonstrate the ability to quantitatively determine low-polarity analyte in aqueous matrix by applying LC-MS/MS technique at a very low level.

    Entreprendre une recherche sur la politique et la législation en matière d'éducation des adultes, qui couvre plusieurs secteurs, paraît une gageure pour plusieurs raisons: difficultés dans la constitution de plusieurs équipes de recherche avec plusieurs spécialistes ou personnes ressources, difficultés dans la collecte des données, étendue et complexité des domaines à explorer et des points à prendre en compte dans la rédaction, etc. En dépit de ces difficultés majeures, l'essentiel du travail a été accompli dans le souci de respecter les exigences imposées. A l'analyse, nous constatons que plusieurs partenaires interviennent dans la formation, l'éducation et l'encadrement des adultes, et que dans le secteur public, les structures ne sont pas "logées à la même enseigne": Si la formation professionnelle a bénéficié de conditions réellement favorables pour son expansion et son développement, les autres secteurs, sans avoir été négligés, n'ont pas connu les mêmes faveurs. Ainsi plusieurs lois et mesures importantes ont été votées et prises en vue de la dynamisation de la formation professionnelle, alors que le secteur de l'agriculture, qui est la base de succès du développement du pays et occupe 55% de la population, n'a pas bénéficié d'une véritable politique éducative en faveur des agriculteurs. Il en est de même pour l'alphabétisation. On déplore constamment l'absence de politique élaborée et appliquée à l'échelle nationale. Aucune mesure politique n'a été votée par l'Assemblée nationale, alors que l'alphabétisation devrait constituer le levier du développement de l'éducation des adultes en Côte d'lvoire.

    Les premières législations antipollution ont été mises en place suite à la détection, aux Etats Unis plus particulièrement en Californie, du smog photochimique et des pluies acides, néfastes pour la faune et la flore. Les estimations de la contribution de l'automobile aux émissions de composés, considérés comme précurseurs de ces phénomènes, ont été suffisantes pour provoquer la mise en place de normes draconiennes en matière d'émissions automobiles. Les matériaux catalytiques ont été évalués en tant que solution possible pour réduire les émissions à l'échappement. En Europe, l'utilisation des catalyseurs trois voies a été généralisée sur les véhicules essence fonctionnant à richesse stoechiométrique à partir de 1993. Une nouvelle génération de catalyseurs appelée piège à oxydes d'azote (NOx) est maintenant nécessaire pour le post-traitement des gaz d'échappement des motorisations à essence fonctionnant en mélange pauvre (combustion en présence d'un excès d'oxygène) pour diminuer la consommation et par conséquent réduire les émissions du CO2 connu pour son impact sur l'effet de serre. La dépollution des moteurs diesel via un catalyseur d'oxydation a été généralisée en Europe depuis 1996. La sévérisation des normes européennes impose pour les moteurs diesel le recours à des matériaux spécifiques pour le traitement des oxydes d'azotes et des particules par l'intermédiaire de filtres à particules dont l'efficacité de filtration est supérieure à 95%, mais doivent subir des régénérations périodiques.

    Seismic data analysis of the Qasbat-Tadla Basin allows the deciphering of the main tectonic and sedimentary events that characterised the Hercynian orogen and its role in the basin's structural development. The global tectono-sedimentary framework involves structural evolution of an orogenic foreland basin and was the source of rising geotherms in an epizonal metamorphic environment. The complementary effects of these parameters has led to different source rock maturity levels, ranging from oil producing to graphite domains. Different maturity levels result from three distinct structural domains within the basin, each of which exhibit characteristic geodynamic features (tectonic contraints, rate of subsidence, etc.).

Résumé La diversité des populations et des communautés microbiennes dans le sol et le sous-sol est présentée dans cet article. Les chercheurs s'interrogent fréquemment sur la diversité microbienne du sous-sol, sur les interactions entre organismes et sur les mécanismes qui permettent le maintien des communautés microbiennes souterraines. Il existe des communautés microbiennes anérobies hétérotrophes dans des grès ou dans des sédiments sableux relativement perméables, à proximité de dépôts riches en matières organiques. Ces micro-organismes semblent se maintenir grâce à la consommation de composés organiques provenant des dépôts organiques voisins. Les sources de matériel organique jouant le rôle de donneur d'électrons sont constituées par des sédiments éocènes riches en lignite situés sous la plaine littorale du Texas, les schistes riches en matières organiques du Crétacé du sud-ouest des États-Unis, ainsi que les argiles contenant des matériaux organiques et des bactéries de fermentation de la plaine littorale atlantique. En outre, il existe des communautés fortement diversifiées dans des régions où aucune source de matière organique n'existe, mais où sont présentes des roches ignées. Le sous-sol riche en basalte de la vallée de la Columbia au Canada et les régions granitiques de Suède en sont des exemples. Ces communautés microbiennes souterraines semblent se maintenir par l'action de bactéries lithotrophes se développant grâce à l'hydrogène qui est produit par réactions chimiques dans le sous-sol. Il existe d'autres communautés microbiennes de profondeur dans les sédiments profonds des océans. Ces systèmes sont souvent associés à un métabolisme anérobie et à une réduction des sulfates. La colonisation microbienne s'étend jusqu'à des profondeurs où les températures élevées limitent leur capacité de survie. Les sources d

    In spodosols of Gascony (France), conversion of maritime pine stands into maize cropping leads to an incorporation of maize organic matter, which changed the isotopic ( δ13C) and phenolic signature in A and L horizons of soil. Hydrolysis of phenol lignin in forests and cultivated soils showed the predominance of vanillic units under forest and the early but moderate incorporation of cinnamic acids. Incorporation of syringic units appeared higher, related to a large maize production of stable syringic phenols. Syringic units represented a long-term marker of maize inputs in soils, whereas vanillic units revealed the degradation of forest organic matter.

The table includes the discovery measurements from the ELODIE spectrograph at Observatoire Haute Provence and subsequent additional monitoring. We took these radial velocity measurements from the Naef et al. 2004 (Cat. J/A+A/414/351) compilation. We also included the legacy data set from Lick Observatory observed with the Hamilton spectrograph, taking measurements from the self-consistent reprocessing of all the Lick spectra presented by Fischer et al. 2014 (Cat. J/ApJS/210/5). Finally, we included more recent additional monitoring from the High Resolution Echelle Spectrometer (HIRES) at the Keck Observatory, and extracted RVs from observations with the High Accuracy Radial velocity Planet Searcher (HARPS) at the ESO-3.6m telescope in 2013 (ESO program ID 091.C-0271, PI: Santos). The reduced HARPS spectra were obtained from the ESO Science Archive (http://archive.eso.org/wdb/wdb/adp/phase3_spectral/query). (1 data file).

Afin de réduire les erreurs de prédiction de la variance, la distance entre les points de mesure doit être inférieure au double de l'écart-type du panache examiné. La dimension totale de l'ensemble doit couvrir une étendue de plusieurs écarts-types du panache pour éviter qu'une partie de la matière échappe à la zone surveillée. Des simulations numériques du panache en dispersion (les calculs de comparaison sont basés sur 9000 nœuds avec 30 points de mesure) montrent que le centre vertical et le centre horizontal de la matière dispersée ont été bien prédits à tous les degrés d'hétérogénéité, de même que pour les variances horizontales. Les variances verticales ont été plus sensibles aux erreurs de prédiction, mais les estimations étaient du même ordre de grandeur que les valeurs réelles. Resumen Un número pequeño de puntos de medida puede producir un sesgo en la caracterización en campo del flujo y transporte de solutos en la zona no saturada. La simulación de transporte advectivo (no difusivo) de un penacho Gaussiano a travs de un conjunto de 30 puntos de medida regularmente distribuidos revelan fluctuaciones temporales regulares de los momentos espaciales del penacho. Una distribución irregular de puntos de medida predijo a su vez fluctuaciones irregulares, más alejadas de la realidad, por lo que se recomienda el uso de esquemas de muestreo regulares. Los momentos espaciales fueron sensibles a la relación entre tamaño del penacho y distancia entre puntos de medida. Para reducir los errores en la predicción de la varianza, la distancia entre puntos de observación debe ser menor que dos veces la desviación estándar del penacho. El tamaño del área muestreada debe cubrir varias desviaciones estándar del penacho para evitar perder parte de la masa. Las simulaciones numricas en un penacho dispersivo, comparando los c

    Les étoiles se forment lors de l'effondrement de nuages de gaz et de poussière. Dans l'environnement proche de l'étoile naissante la matière se concentre dans un plan équatorial que l'on appelle disque protoplanétaire. Les astronomes pensent que les planètes se forment au sein de cette masse de gaz et de poussière orbitant autour de l'étoile. Pour sonder ces disques à des échelles correspondant aux orbites des futures planètes, il convient d'observer dans l'infrarouge à très haute résolution spatiale. L'interférométrie infrarouge est donc un outil idéal pour étudier les conditions physiques des disques protoplanétaires. Dans ce mémoire, je décris les premiers pas de l'interférométrie infrarouge, depuis la mise au point des petits interféromètres PTI et IOTA jusqu'à la construction de l'instrument AMBER au foyer de l'interféromètre du VLT. Je décris aussi les résultats d'une piste de recherche technologique particulièrement attrayante dans le cas de l'interférométrie infrarouge et issue des technologies des autoroutes de l'information: l'optique intégrée appliquée à la combinaison de plusieurs faisceaux en astronomie. Je montre ensuite comment à partir des observations obtenues à partir de ces instruments, il est possible de contraindre la physique des disques autour des étoiles jeunes. Gráce à la résolution spectrale nouvellement disponible sur ces instruments, pour la première fois nous pouvons séparer des phénomènes physiques aussi différents que l'accrétion de matière sur l'étoile et l'éjection de particules par des vents dont l'origine précise est encore mal connue. Les résultats présentés dans ce mémoire ont été obtenus principalement à partir d'observations sur les systèmes jeunes FU Ori et MWC 297 effectuées par AMBER sur le VLTI, mais aussi par les petits interféromètres infrarouges PTI et IOTA. Je développe aussi les travaux de modélisation de la structure verticale des disques associ

    In Quebec (Canada), the Work-Oriented Training Path, a work-study program, prepares students who are having difficulty at school for the job market. Occupational health and safety is an important part of their training. This article aims to analyze the impact of gender on the interpersonal dynamics among teachers, trainees, and key actors from the businesses involved. This article also looks at the influence of gender on teachers' strategies and capacity to act regarding occupational health and safety. Using a work activity analysis lens, a multiple case-study analysis of teachers' work activity was carried out. The findings show that gendered social relationships create a specific supervisory context that influences occupational health and safety training. Solutions aimed at reducing the negative impact of gender-associated prejudice on work injury prevention include training for teachers, attention to work organization at the schools, and the creation of cohesive teachers' work teams. Résumé Au Québec, le Parcours de formation axée sur l'emploi (WOTP), un programme en alternance, offre une préparation au marché du travail aux élèves en difficultés scolaires. La santé et la sécurité du travail (SST) est un enjeu important de la formation. L'article vise à analyser l'impact du genre dans la dynamique relationnelle entre les enseignant.es, leurs élèves et les interlocuteurs clés des entreprises impliquées, et son influence sur les stratégies et la capacité d'agir des enseignant.es en matière de SST. Une analyse de cas multiples basée sur l'analyse ergonomique de l'activité des enseignants a été menée. Les résultats montrent que les relations sociales de genre déterminent un contexte spécifique de supervision qui influence la formation à la SST. La formation des enseignant.es, l'organisation scolaire et la création de collectifs enseignants cohésifs sont des pistes de solution pour réduire l'effet négatif des préjugés liés au genre

    Résumé La politique actuelle de lutte contre le sida qui repose sur l’extension de l’accès aux traitements et à la prévention exige qu’une proportion élevée de la population connaisse son statut en matière de VIH. Pour cela, l’OMS a proposé le développement de stratégies communautaires délivrant le dépistage et le conseil au-delà des services de soins, comme le test à domicile ou les campagnes de sensibilisation et dépistage de grande envergure, appliqués en Afrique australe et de l’Est. Pour définir les stratégies pertinentes dans des régions de basse prévalence comme l’Afrique de l’Ouest, les expériences communautaires de promotion du dépistage doivent y être évaluées. Cet article présente une évaluation des campagnes au Burkina Faso du point de vue des usagers. Dans le cadre d’un projet sur les pratiques et l’éthique du dépistage dans quatre pays africains (MATCH), une enquête qualitative spécifique a été menée pendant la campagne de 2008, auprès de personnes ayant fait le test pendant la campagne, ayant fait le test hors campagne ou n’ayant pas fait le test. Les appréciations sont globalement très favorables aux campagnes, notamment à cause de l’information dispensée, l’accessibilité des sites, la gratuité du test, la qualité des services et l’effet d’entrainement. Les limites ou critiques sont essentiellement liées à l’affluence ou à la crainte de ne pas être soutenu en cas de résultat positif. La démarche de recours au test ne fait plus l’objet de suspicion, au moins pendant la campagne. Cette « normalisation » du recours au test et la mobilisation collective facilitent des pratiques en groupe, ce qui peut rendre difficile de garder son statut VIH secret. L’évaluation des campagnes par les usagers les présente comme une opportunité pour accéder facilement au test et pour communiquer à ce sujet dans divers espaces sociaux à partir des informations délivrées sur le VIH

    The 3rd International Conference on the Physics of Optical Materials and Devices (ICOM2012) was held in Belgrade (Serbia) from 2 to 6 September 2012 (figure 1). The conference was organized by the Vinča Institute of Nuclear Sciences, University of Belgrade (Serbia) and the Laboratoire de Chimie de la Matière Condensée de Paris (France), and supported by the Ministry of Education, Science and Technological Development of the Republic of Serbia and Optical Society of America. ICOM2012 was a follow-up to the two previous, successful ICOM conferences held in Herceg Novi in 2006 and 2009. The conference aimed at providing a forum for scientists in optical materials to debate on: • Luminescent materials and nanomaterials • Hybrid optical materials (organic/inorganic) • Characterization techniques of optical materials • Luminescence mechanisms and energy transfers • Theory and modeling of optical processes • Ultrafast-laser processing of materials • Optical sensors • Medical imaging • Advanced optical materials in photovoltaics and biophotonics • Photothermal and photoacoustic spectroscopy and phenomena The conference stressed the value of a fundamental scientific understanding of optical materials. A particular accent was put on wide band-gap materials in crystalline, glass and nanocrystalline forms. The applications mainly involved lasers, scintillators and phosphors. Rare earth and transition metal ions introduced as dopants in various hosts were considered, and their impact on the optical properties were detailed in several presentations. This volume contains selected contributions of speakers and participants of the ICOM2012 conference. The conference provided a unique opportunity for about 200 scientists from 32 countries to discuss recent progress in the field of optical materials. During the three and half days, 21 invited talks and 52 contributed lectures were given, with a special event in memory of our dear colleague Professor Dr Tsoltan

    Key comparison CCQM-K60 was performed to assess the analytical capabilities of national metrology institutes (NMIs) to accurately quantitate the mass fraction of selenomethionine (SeMet) and total selenium (at low mg kg-1 levels) in selenised wheat flour. It was organized by the Inorganic Analysis Working Group (IAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM) as a follow-up key comparison to the previous pilot study CCQM-P86 on selenised yeast tablets. LGC Limited (Teddington, UK) and the Institute for National Measurement Standards, National Research Council Canada (NRCC, Ottawa, Canada) acted as the coordinating laboratories. CCQM-K60 was organized in parallel with a pilot study (CCQM-P86.1) involving not only NMIs but also expert laboratories worldwide, thus enabling them to assess their capabilities, discover problems and learn how to modify analytical procedures accordingly. Nine results for total Se and four results for SeMet were reported by the participant NMIs. Methods used for sample preparation were microwave assisted acid digestion for total Se and multiple-step enzymatic hydrolysis and hydrolysis with methanesulfonic acid for SeMet. For total Se, detection techniques included inductively coupled plasma mass spectrometry (ICP-MS) with external calibration, standard additions or isotope dilution analysis (IDMS); instrumental neutron activation analysis (INAA); and graphite furnace atomic absorption spectrometry (GFAAS) with external calibration. For determination of SeMet in the wheat flour sample, the four NMIs relied upon measurements using species-specific IDMS (using 76Se-enriched SeMet) with HPLC-ICP-MS. Eight of the nine participating NMIs reported results for total Se within 3.5% deviation from the key comparison reference value (KCRV). For SeMet, the four participating NMIs reported results within 3.2% deviation from the KCRV. This shows that the performance of the majority of the CCQM-K60 participants was very good

    Greenhouse heating can be achieved using various systems, for the generator as well as for the exchanger. The exchanger characteristics involve quite different modes of energy distribution, with differing agronomic and economic consequences. This paper focuses on two ground-level heating systems with low temperature (20 40°C) water circulation: a “radiant mulch” exchanger, composed of a network of ground-level heating hoses, and a “buried pipes” exchanger, composed of a network of under-ground pipes. The first part of the paper develops a model for these exchangers and its integration into a previously described greenhouse global model. The second part compares the effects of these exchangers on the greenhouse energetical behaviour with those of classic aerial metallic pipes with hot (50 70°C) water circulation. Le chauffage des serres agricoles peut être réalisé avec divers types de systèmes, tant pour le générateur que pour l'échangeur situé au sein de la serre. Les caractéristiques de l'échangeur induisent des modes de distribution de l'énergie très différents, dont les conséquences agronomiques et économiques peuvent être importantes. Le présent article s'intéresse à deux types d'échangeurs à circulation d'eau “à basse température” (20 40°C) localisés au niveau du sol de la serre: chauffage par gaines en matière plastique posées à même le sol (ou “paillage radiant”), chauffage par réseau de tubes enterrés à faible profondeur dans le sol de la serre. Une première partie développe une modélisation de ces échangeurs et son intégration dans un modèle plus global de la serre agricole, déjà présenté par ailleurs. Une seconde partie exploite cette modélisation en effectuant une analyse comparative de ces échangeurs avec un échangeur de référence constitué de tubes métalliques aériens à circulation d'eau chaude (50 70°C), très classiquement utilisé dans les serres.

    L'infertilité d'origine tubo-péritonéale est toujours d'actualité, sa fréquence reste stable, sinon croissante. La coelioscopie permet à la fois d'affirmer l'atteinte tubaire et de proposer un geste thérapeutique adapté. Le but de notre travail est d’évaluer les résultats de la chirurgie laparoscopique des pathologies tubaires en termes de grossesses obtenues. Il s'agit d'une étude rétrospective descriptive, analytique et longitudinale. Nous avons colligé les patientes suivies pour infertilité et opérées pour pathologies tubaires distales au service A du centre de maternité et de néonatologie de Tunis. Nous avons étudié les caractéristiques épidémiologiques et cliniques des patientes, les résultats de l'imagerie et détaillé les gestes chirurgicaux réalisés. Les résultats de la chirurgie tubaire distale étaient exprimés en termes de grossesses obtenues avec un recul minimal de 12 mois et maximal de 5 ans. 898 patientes étaient prises en charge dans le service pour une infertilité dont 52 patientes avaient répondu aux critères d'inclusion à l’étude. La sensibilité de l'hystérosalpingographie en matière de lésions tubaire était de 69% et la spécificité de 100%. Selon le score d'opérabilité tubaire distale, 23% des lésions étaient classées au stade 4 et 13.46% au stade 1. Le taux de grossesses spontanées était de 8.69%, soit 13% des fimbrioplasties et 4% des néosalpingostomie. Le délai de conception allait de 4 à 9 mois. Les antécédents ou stigmates d'infection pelvienne étaient retenus comme facteur de mauvais pronostic. Une sélection rigoureuse des patientes à partir des données de l'hystérographie et de la coelioscopie est indispensable afin de déterminer les patientes candidates à une chirurgie réparatrice ou à une fécondation in vitro PMID:26113892

L'intérêt pour la science de la haute fiabilité, mise au point à l'origine dans des secteurs comme l'aviation commerciale, qui ont un bilan exceptionnel en matière de sécurité, est une nouvelle tendance en soins de santé qui pourrait aider les organisations et les systèmes à atteindre le but ultime : zéro préjudice subi par les patients. Cet article fait valoir que zéro préjudice au patient est un impératif fondamental et que la science de la haute fiabilité peut aider à accélérer et à soutenir les progrès vers ce but vital. Bien que les pratiques utilisées dans d'autres secteurs ne soient pas facilement transférables aux soins de santé et qu'il n'existe pas encore un seul modèle éprouvé pour les organisations à haute fiabilité en santé, des organisations de premier plan commencent à faire la démonstration de stratégies efficaces propres aux soins de santé. L'expérience du réseau international d'organisations partenaires du groupe Studer est utilisée pour illustrer et comprendre ces premiers efforts. Le cadre Evidence-Based Leadership SM (leadership fondé sur les données probantes) du groupe Studer est appliqué dans différents milieux de soins de santé pour transformer la culture et la gestion du changement visant à favoriser une haute fiabilité. Il propose une démarche et des ressources pour progresser vers le but zéro préjudice subi par les patients et tous les avantages liés à l'utilisation efficiente de nos précieuses ressources en soins de santé.

    While the need to reconcile work and family life has been recognized in discrete ways in legislation and policy over the years, there has not been a substantial shift away from the archetype of the "unencumbered" (male) worker to a new model of the "normal" worker. In Canada and elsewhere, legislative protection does not allow women or men to effectively reconcile work and family responsibilities over the life cycle. This paper examines the different ways in which work-family balance is regulated, with a focus on the Canadian federal jurisdiction and the province of Quebec, and underlines the need for coherent labor and social policy. The paper also explores the development of multi-stakeholder initiatives on work-family balance, including the development of voluntary standards and a proposal for a work-family "framework" law to ensure coherence among different laws and programs affecting work-family balance. The paper concludes by confirming the need to move away from an individualized approach toward a more mainstreamed and collectivized approach to work-family balance. Résumé Bien que la nécessité de concilier travail et vie familiale ait fait l'objet d'une reconnaissance timide dans la législation et les politiques publiques au fil des ans, il n'y a pas eu de changement substantiel de l'archétype du travailleur « sans engagements » (homme) vers un nouveau modèle de « travailleur normal ». Au Canada et ailleurs, la protection législative ne permet pas aux femmes ou aux hommes d'arrimer efficacement leurs responsabilités professionnelles et familiales au cours de leur vie. Cet article examine les différentes façons dont la conciliation travail-famille est réglementée, particulièrement en droit fédéral canadien et dans la province de Québec, et souligne la nécessité d'une politique sociale et de travail cohérente. Le texte explore également le développement d'initiatives multipartites, y compris l'élaboration de normes volontaires de style ISO et une proposition de loi-cadre travail-famille afin d'assurer une cohérence entre les différents lois et programmes touchant la conciliation famille-travail au Québec. L'article conclut en confirmant la nécessité de passer d'une approche individualisée à une approche plus intégrée et collectivisée de la conciliation travail-famille.

    The abundance of gold and selected trace elements in magmatic sulfide and rock-forming minerals from Silurian-Devonian granitoids in southwestern New Brunswick were quantitatively analyzed by laser-ablation inductively coupled plasma mass-spectrometry. Gold is mainly hosted in sulfide minerals (i.e., chalcopyrite, pyrrhotite, and pyrite), in some cases perhaps as submicron inclusions (nanonuggets). Gold is below detection (<0.02 ppm) in major rock-forming minerals (i.e., plagioclase, K-feldspar, biotite, hornblende, and muscovite) and oxides (i.e., magnetite, and ilmenite). Gold distribution coefficients between sulfide and granitoid melt are calculated empirically as: 2!1!+- % feaaeaart1ev0aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX % garmWu51MyVXgatuuDJXwAK1uy0HwmaeHbfv3ySLgzG0uy0Hgip5wz % aebbnrfifHhDYfgasaacH8qrps0lbbf9q8WrFfeuY-Hhbbf9v8qqaq % Fr0xc9pk0xbba9q8WqFfea0-yr0RYxir-Jbba9q8aq0-yq-He9q8qq % Q8frFve9Fve9Ff0dmeaabaqaciGacaGaaeqabaWaaeWaeaaakeaaca % WGebWaa0baaSqaaiaabgeacaqG1baabaGaae4yaiaabchacaqG5bGa % ae4laiaab2gacaqGLbGaaeiBaiaabshaaaGccqGH9aqpcaaI5aGaaG % inaiaaiIdacqGHXcqScaaIYaGaaGOnaiaaiMdacaGGSaGaaeiiaiaa % dseadaqhaaWcbaGaaeyqaiaabwhaaeaacaqGWbGaae4Baiaab+caca % qGTbGaaeyzaiaabYgacaqG0baaaOGaeyypa0JaaGymaiaaiwdacaaI % WaGaeyySaeRaaGioaiaaiodacaGGSaGaaeiiaiaabggacaqGUbGaae % izaiaabccacaWGebWaa0baaSqaaiaabgeacaqG1baabaGaaeiCaiaa % bMhacaqGVaGaaeyBaiaabwgacaqGSbGaaeiDaaaakiabg2da9iaaio % dacaaI2aGaaGOmaiabgglaXkaaiMdacaaI2aaaaa!6E8F!

This result suggests that gold behavior in the granitoid systems is controlled by the conditions of sulfur saturation during magmatic evolution; the threshold of physiochemical conditions for sulfur saturation in the melts is a key factor affecting gold activity. Gold behaves incompatibly prior to the formation of sulfide liquids or minerals, but it

    During this project we observed with two Fine Guidance Sensor (FGS) units: FGS 3 from 1992 to 2000, and FGS 1r from 2000 to 2009. FGS 1r replaced the original FGS 1 during Hubble Space Telescope (HST) Servicing Mission 3A in late 1999. We included visual, photographic, and CCD observations of separations and position angles from Geyer et al. 1988AJ.....95.1841G for our analysis of GJ 65 AB. We include a single observation of G 193-027 AB from Beuzit et al. 2004A&A...425..997B, who used the Adaptive Optics Bonnette system on the Canada-France-Hawaii Telescope (CFHT). For GJ 65 AB we include five Very Large Telescope/NAos-COnica (VLT/NACO) measures of position angle and separation (Kervella et al. 2016A&A...593A.127K). For our analysis of GJ 623 AB, we included astrometric observations (Martinache et al. 2007ApJ...661..496M) performed with the Palomar High Angular Resolution Observer (PHARO) instrument on the Palomar 200in (5m) telescope and with the Near InfraRed Camera 2 (NIRC2) instrument on the Keck II telescope. Separations have typical errors of 2mas. Position angle errors average 0.5°. Measurements are included for GJ 22 AC from McCarthy et al. 1991AJ....101..214M and for GJ 473 AB from Henry et al. 1992AJ....103.1369H and Torres et al. 1999AJ....117..562T, who used a two-dimensional infrared speckle camera containing a 58*62 pixel InSb array on the Steward Observatory 90in telescope. We also include infrared speckle observations by Woitas et al. 2003A&A...406..293W, who obtained fourteen separation and position angle measurements for GJ 22 AC with the near-infrared cameras MAGIC and OMEGA Cass at the 3.5m telescope on Calar Alto. We also include a few speckle observations at optical wavelengths from the Special Astrophysical Observatory 6m Bolshoi Azimuth Telescope (BTA) and 1m Zeiss (Balega et al. 1994, Cat. J/A+AS/105/503), from the CFHT (Blazit et al. 1987) and from the Differential Speckle Survey Instrument (DSSI) on the Wisconsin, Indiana, Yale

    éformations subies par la section d'un faisceau lumineux au cours de sa propagation, à la distribution matérielle et énergétique qu'il rencontre sur son trajet entre la source et l'observateur. Les deux contributions aux effets d'optique apparaissant dans ces équations (et leurs solutions) sont les termes de matière et les termes de cisaillement. Nous montrons comment une nouvelle distance peut être introduite, la distance optique, en fonction de laquelle les équations se simplifient et de nouvelles solutions analytiques peuvent être établies. En particulier, nous démontrons que la formule d'amplification gravitationnelle peut s'écrire sous une forme très générale sous la simple hypothèse que l'Univers est en moyenne de type Friedmann-Robertson-Walker. De nouveaux résultats sont aussi présentés concernant la distribution de probabilité des amplifications, les rapports entre termes de matière et termes de cisaillement (les premiers donnant la moyenne des seconds), et le problème de la conservation de l'énergie. Nous rappelons comment une formule analytique peut être obtenue pour des amplifications multiples et présentons des solutions nouvelles au problème de l'amplification par des hétérogénéités à très grande échelle. Enfin, les effets de décalages spectraux gravitationnels sont aussi considérés, qu'ils soient dus à des effets de traversée d'excès de densité, ou intrinsèques à ceux-ci ; dans ce dernier cas, une généralisation de solutions déjà connues est proposée. On considère ensuite le problème de la mise en évidence observationnelle des divers effets d'optique gravitationnelle, qu'ils soient de nature statistique ou qu'ils concernent des objets individuels. A la suite d'une analyse décrivant la dépendance de la formule d'amplification en fonction des différents paramètres y intervenant, nous insistons tout particulièrement sur le rôle cosmologique que jouent probablement les amas de galaxies très riches de d

  19. Hydrogeologic uncertainties and policy implications: The Water Consumer Protection Act of Tucson, Arizona, USA

    NASA Astrophysics Data System (ADS)

    Wilson, L. G.; Matlock, W. G.; Jacobs, K. L.

    The 1995 Water Consumer Protection Act of Tucson, Arizona, USA (hereafter known as the Act) was passed following complaints from Tucson Water customers receiving treated Central Arizona Project (CAP) water. Consequences of the Act demonstrate the uncertainties and difficulties that arise when the public is asked to vote on a highly technical issue. The recharge requirements of the Act neglect hydrogeological uncertainties because of confusion between "infiltration" and "recharge." Thus, the Act implies that infiltration in stream channels along the Central Wellfield will promote recharge in the Central Wellfield. In fact, permeability differences between channel alluvium and underlying basin-fill deposits may lead to subjacent outflow. Additionally, even if recharge of Colorado River water occurs in the Central Wellfield, groundwater will become gradually salinized. The Act's restrictions on the use of CAP water affect the four regulatory mechanisms in Arizona's 1980 Groundwater Code as they relate to the Tucson Active Management Area: (a) supply augmentation; (b) requirements for groundwater withdrawals and permitting; (c) Management Plan requirements, particularly mandatory conservation and water-quality issues; and (d) the requirement that all new subdivisions use renewable water supplies in lieu of groundwater. Political fallout includes disruption of normal governmental activities because of the demands in implementing the Act. Résumé La loi de 1995 sur la protection des consommateurs d'eau de Tucson (Arizona, États-Unis) a été promulguée à la suite des réclamations des consommateurs d'eau de Tucson alimentés en eau traitée à partir à la station centrale d'Arizona (CAP). Les conséquences de cette loi montrent les incertitudes et les difficultés qui apparaissent lorsque le public est appeléà voter sur un problème très technique. Les exigences de la loi en matière de recharge négligent les incertitudes hydrogéologiques du fait de la

    We have compiled a catalog of the previously known members of Cha I. We began with the census from Luhman 2008 (Cat. J/ApJ/675/1375). we adopt ChaJ11100159-7738052 as a previously known member, which was presented in Luhman 2007 (Cat. J/ApJS/173/104) as a possible field M9-L1 dwarf. We also include in our census the M9 companion to CT Cha (Schmidt et al. 2008A&A...491..311S) and five new M4 members from Frasca et al. 2015 (Cat. J/A+A/575/A4) and Sacco et al. 2017 (Cat. J/A+A/601/A97): 2MASSJ10575375-7724495, 2MASSJ10563146-7618334, 2MASSJ11213079-7633351, 2MASSJ11130450-7534369, and 2MASSJ11090915-7553477. We list the 244 previously known members and the 6 new members from this study in Table1. Luhman et al. (2005ApJ...635L..93L) obtained images of a 13.3'*16.7' area of the southern subcluster in Cha I with the Wide Field Camera (WFC) aperture of the Advanced Camera for Surveys (ACS) on board HST. The observations were performed on 2004 August 21 and 2005 February 16 with the F775W and F850LP filters. To measure proper motions for sources detected in those data, we repeated those observations in the F850LP filter on 2009 August 20 and 2011 February 13 through program 11695. Portions of Cha I have been imaged at several epochs with the Infrared Array Camera (IRAC) on Spitzer. Those observations occurred during both the cryogenic and post-cryogenic phases of the mission. The cryogenic phase began at launch in 2003 August and continued until 2009 May, when the liquid helium was depleted. During that time, IRAC operated with four 256*256 arrays that collected images in broadband filters at 3.6, 4.5, 5.8, and 8.0μm, which are denoted as [3.6], [4.5], [5.8], and [8.0]. For each array, the plate scale was 1.2''/pixel and the field of view (FOV) was 5.2'*5.2'. Point sources within the images have a FWHM of 1.6''-1.9'' for [3.6]-[8.0]. We compiled photometry from previous surveys for low-mass members of Cha I and publicly available catalogs, which consist of F775W and F850

    Les décisions en matière de réglementation et les documents scientifiques au sujet de la prise en charge du trouble de déficit de l’attention avec hyperactivité (TDAH) soulèvent des questions quant à l’innocuité des médicaments et à l’évaluation convenable à effectuer avant le traitement afin de déterminer la pertinence d’une pharmacothérapie. Ce constat est particulièrement vrai en présence de cardiopathies structurelles ou fonctionnelles. Le présent article contient l’analyse des données disponibles, y compris les publications révisées par des pairs, des données tirées du site Web de la Food and Drug Administration des États-Unis au sujet des réactions indésirables déclarées chez des enfants qui prennent des stimulants, ainsi que des données de Santé Canada sur le même problème. Des lignes directrices consensuelles sur l’évaluation pertinente sont proposées d’après l’apport des membres de la Société canadienne de pédiatrie, de la Société canadienne de cardiologie et de l’Académie canadienne de psychiatrie de l’enfant et de l’adolescent, qui possèdent notamment des compétences et des connaissances précises tant dans le secteur du TDAH que de la cardiologie pédiatrique. Le présent document de principes prône une anamnèse et un examen physique détaillés avant la prescription de stimulants et s’attarde sur le dépistage des facteurs de risque de mort subite, mais il ne contient pas de recommandations systématiques de dépistage électrocardiographique ou de consultations avec un spécialiste en cardiologie, à moins que les antécédents ou que l’examen physique ne le justifient. Le document contient un questionnaire pour repérer les enfants potentiellement vulnérables à une mort subite (quel que soit le type de TDAH ou les médicaments utilisés pour le traiter). Même si les recommandations dépendent des meilleures données probantes disponibles, le comité s’entend pour affirmer que

  6. Static electricity as a hazard in industry

    van Laar, Ir. G. F. M.

    1991-08-01

    Looking at the German and Dutch statistics, the percentage of dust explosions in all industries dealing with explosible dust-air mixtures which have been ignited by electrostatic discharges is about 8-10%. However, in the plastics industry this value is much higher: 25%. In particular in the last few years some rather large industrial incidents probably have been caused by electrostatic charges. To understand why accidents may happen due to static electricity the several dangerous electrostatic discharges will be discussed briefly in connection with dust explosion hazards. In particular the propagating brush discharge and the cone or " Maurer " discharge are important. Ignitions are caused mainly in the case of easily ignitable powders or hybrid mixtures (powders in combination with flammable vapours) due to isolated conductors and non-conducting materials as the product itself or such process parts as flexible hoses, internally coated silos and ducts. To illustrate how hazards by electrostatic discharges may develop in real life both on a small and a large scale a few examples will be briefly discussed. Une consultation des statistiques allemandes et néerlandaises révèle que dans toutes les industries traitant des mélanges poussière-air explosifs le pourcentage des explosions de poussière qui se sont produites par des décharges électrostatiques ne s'élève qu'à environ 8-10 %. Dans l'industrie des matières plastiques cependant, ce pourcentage est bien plus grand: 25 %. Les dernières années en particulier nous ont rapporté plusieurs incidents industriels assez graves qui sont probablement causés par des charges électrostatiques. Pour comprendre comment des accidents pareils dus à l'électricité statique peuvent se produire, les différentes décharges électrostatiques dangereuses pouvant produire des explosions de poussière se discuteront brièvement. Ce sont surtout la décharge brosse de surface et la décharge " Maurer " qui sont d

    2003-07-01

    The General Assembly of the International Astronomical Union (IAU), meeting in Sydney (Australia), has appointed the ESO Director General, Dr. Catherine Cesarsky, as President Elect for a three-year period (2003-2006). The IAU is the world's foremost organisation for astronomy, uniting almost 9000 professional scientists on all continents. The IAU General Assembly also elected Prof. Ron Ekers (Australia) as President (2003 - 2006). Dr. Cesarsky will then become President of the IAU in 2006, when the General Assembly next meets in Prague (The Czech Republic). Dr. Cesarsky is the first woman scientist to receive this high distinction. "The election of Catherine Cesarsky as President-Elect of the IAU is an important recognition for a scientist who has made impressive contributions to various areas of modern astrophysics, from cosmic rays to the interstellar medium and cosmology" , commented the outgoing IAU President, Prof. Franco Pacini. "It is also an honour and an important accolade for the European astronomical community in general and ESO in particular." Dr. Cesarsky, who assumed the function as ESO Director General in 1999, was born in France. She received a degree in Physical Sciences at the University of Buenos Aires and graduated with a PhD in Astronomy in 1971 from Harvard University (Cambridge, Mass., USA). Afterwards she worked at the California Institute of Technology (CALTECH). In 1974, she became a staff member of the Service d'Astrophysique (SAp), Direction des Sciences de la Matière (DSM), Commissariat à l'Energie Atomique (CEA) (France). As Director of DSM (1994 - 1999), she was leading about 3000 scientists, engineers and technicians active within a broad spectrum of basic research programmes in physics, chemistry, astrophysics and earth sciences. Dr. Cesarsky is known for her successful research activities in several central areas of modern astrophysics. She first worked on the theory of cosmic ray propagation and acceleration, and galactic gamma

  10. La genèse du concept de champ quantique

    NASA Astrophysics Data System (ADS)

    Darrigol, O.

    This is a historical study of the roots of a concept which has proved to be essential in modern particle physics : the concept of quantum field. The first steps were accomplished by two young theoreticians : Pascual Jordan quantized the free electromagnetic field in 1925 by means of the formal rules of the just discovered matrix mechanics, and Paul Dirac quantized the whole system charges + field in 1927. Using Dirac's equation for electrons (1928) and Jordan's idea of quantized matter waves (second quantization), Werner Heisenberg and Wolfgang Pauli provided in 1929-1930 an extension of Dirac's radiation theory and the proof of its relativistic invariance. Meanwhile Enrico Fermi discovered independently a more elegant and pedagogical formulation. To appreciate the degree of historical necessity of the quantization of fields, and the value of contemporaneous critics to this approach, it was necessary to investigate some of the history of the old radiation theory. We present the various arguments however provisional or naïve or wrong they could be in retrospect. So we hope to contribute to a more vivid picture of notions which, once deprived of their historical setting, might seem abstruse to the modern user. Nous présentons une étude historique des origines d'un concept devenu essentiel dans la physique moderne des particules : le concept de champ quantique. Deux jeunes théoriciens franchirent les premières étapes : Pascual Jordan quantifia le champ électromagnétique en 1925 grâce aux règles formelles de la mécanique des matrices naissante, et Paul Dirac quantifia le système complet charges + champ en 1927. Au moyen de l'équation de l'électron de Dirac (1928) et de l'idée de Jordan d'ondes de matière quantifiées (deuxième quantification), Werner Heisenberg et Wolfgang Pauli donnèrent en 1929-1930 une extension de la théorie du rayonnement de Dirac et la preuve de son invariance relativiste. Pendant ce temps Enrico Fermi découvrit ind

    The supplementary comparison APMP.QM-S8: determination of mass fraction of benzoic acid, methyl paraben and n-butyl paraben in soy sauce was coordinated by the Health Sciences Authority, Singapore under the auspices of the Organic Analysis Working Group (OAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM). Ten national metrology institutes (NMIs) or designated institutes (DIs) participated in the comparison. All the institutes participated in the comparison for benzoic acid, while six NMIs/DIs participated in the comparison for methyl paraben and n-butyl paraben. The comparison was designed to enable participating institutes to demonstrate their measurement capabilities in the determination of common preservatives in soy sauce, using procedure(s) that required simple sample preparation and selective detection in the mass fraction range of 50 to 1000 mg/kg. The demonstrated capabilities can be extended to include other polar food preservatives (e.g. sorbic acid, propionic acid and other alkyl benzoates) in water, aqueous-based beverages (e.g. fruit juices, tea extracts, sodas, sports drinks, etc) and aqueous-based condiments (e.g. vinegar, fish sauce, etc). Liquid--liquid extraction and/or dilution were applied, followed by instrumental analyses using LC-MS/MS, LC-MS, GC-MS (with or without derivatisation) or HPLC-DAD. Isotope dilution mass spectrometry was used for quantification, except in the case of a participating institute, where external calibration method was used for quantification of all three measurands. The assigned Supplementary Comparison Reference Values (SCRVs) were the medians of ten results for benzoic acid, six results for methyl paraben and six results for n-butyl paraben. Benzoic acid was assigned a SCRV of 154.55 mg/kg with a combined standard uncertainty of 0.94 mg/kg, methyl paraben was assigned a SCRV of 100.95 mg/kg with a combined standard uncertainty of 0.40 mg/kg, and n-butyl paraben was assigned a SCRV of 99.05 mg

    ) used the adaptive optics systems at Keck and Palomar with NIRC2 and PHARO, respectively, and typically observed each target with the J-, H-, and K-band filters. Adams et al. 2012 (Cat. J/AJ/144/42), Adams et al. (2013AJ....146....9A) and Dressing et al. (2014AJ....148...78D) mainly used the Ks filter in their AO observations at the MMT; in addition, they often used the J-band filter when a companion was detected in the Ks image. The field of view of the ARIES instrument on the MMT was 20''*20'', somewhat smaller than that of PHARO at Palomar, and the FWHM of the stellar images varied between about 0.1'' and 0.6''. Kraus et al. 2016 (Cat. J/AJ/152/8) employed adaptive optics imaging and also non-redundant aperture-mask interferometry at Keck with the NIRC2 instrument; the latter technique is limited only by the diffraction limit of the 10m Keck telescope. They used the K' filter for their observations. Baranec et al. 2016 (Cat. J/AJ/152/18) and Ziegler et al. 2016 (AJ accepted, arXiv:1605.03584) observed a sample of KOI host stars at Keck using mostly the K' filter on NIRC2. With the Robo-AO imaging at the Palomar 1.5m telescope, Law et al. 2014 (Cat. J/ApJ/791/35), Baranec et al. 2016 (Cat. J/AJ/152/18), and Ziegler et al. 2016 (AJ accepted, arXiv:1605.03584) covered a total of 3320 KOI host stars. For most observations, they used a long-pass filter whose window starts at 600nm (LP600), which is similar to the Kepler bandpass; they also took data for some stars in the Sloan i-band filter and, more rarely, Sloan r and z filters. The typical FWHM of the observed stellar PSF amounted to 0.12''-0.15''; the images covered a field of view of 44''*44''. Lillo-Box et al. (2012, Cat. J/A+A/546/A10; 2014, Cat. J/A+A/566/A103) used the 2.2m Calar Alto telescope with the AstraLux instrument to obtain diffraction-limited imaging with the lucky imaging technique, typically observing in the i- and z-band filters. This technique involves taking a very large number of short exposures

    The key comparison CCQM-K102: Polybrominated diphenyl ethers in sediment was coordinated by the JRC, Directorate F - Health, Consumers & Reference Materials, Geel (Belgium) under the auspices of the Organic Analysis Working Group (OAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM). Thirteen National Metrology institutes or Designated Institutes and the JRC participated. Participants were requested to report the mass fraction (on a dry mass basis) of BDE 47, 99 and 153 in the freshwater sediment study material. The sediment originated from a river in Belgium and contained PBDEs (and other pollutants) at levels commonly found in environmental samples. The comparison was designed to demonstrate participants' capability of analysing non-polar organic molecules in abiotic dried matrices (approximate range of molecular weights: 100 to 800 g/mol, polarity corresponding to pKow < -2, range of mass fraction: 1-1000 μg/kg). All participants (except one using ultrasonic extraction) applied Pressurised Liquid Extraction or Soxhlet, while the instrumental analysis was performed with GC-MS/MS, GC-MS or GC-HRMS. Isotope Dilution Mass Spectrometry approach was used for quantification (except in one case). The assigned Key Comparison Reference Values (KCRVs) were the medians of thirteen results for BDE 47 and eleven results for BDE 99 and 153, respectively. BDE 47 was assigned a KCRV of 15.60 μg/kg with a combined standard uncertainty of 0.41 μg/kg, BDE 99 was assigned a KCRV of 33.69 μg/kg with a combined standard uncertainty of 0.81 μg/kg and BDE 153 was assigned a KCRV of 6.28 μg/kg with a combined standard uncertainty of 0.28 μg/kg. The k-factor for the estimation of the expanded uncertainty of the KCRVs was chosen as k = 2. The degree of equivalence (with the KCRV) and its uncertainty were calculated for each result. Most of the participants to CCQM-K102 were able to demonstrate or confirm their capabilities in the analysis of non-polar organic

    Under the auspices of the Protein Analysis Working Group (PAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM) a pilot study, CCQM-P55.2, was coordinated by the Bureau International des Poids et Mesures (BIPM) and the Chinese National Institute of Metrology (NIM). Four Metrology Institutes or Designated Institutes and the BIPM participated. Participants were required to assign the mass fraction of human C-peptide (hCP) present as the main component in the comparison sample for CCQM-P55.2. The comparison samples were prepared from synthetic human hCP purchased from a commercial supplier and used as provided without further treatment or purification. hCP was selected to be representative of the performance of a laboratory's measurement capability for the purity assignment of short (up to 5 kDa), non-cross-linked synthetic peptides/proteins. It was anticipated to provide an analytical measurement challenge representative for the value-assignment of compounds of broadly similar structural characteristics. The majority of participants used a quantitative nuclear magnetic resonance spectroscopy (qNMR) corrected for peptide impurities. Other participants provided results obtained by peptide impurity corrected amino acid analysis (PICAA) or elemental analysis (PICCHN). It was decided to assign reference values based on the KCRVs of CCQM-K115 for both the hCP mass fraction and the mass fraction of the peptide related impurities as indispensable contributor regardless of the use of PICAA, mass balance or any other approach to determine the hCP purity. This allowed participants to demonstrate the efficacy of their implementation of the approaches used to determine the hCP mass fraction. In particular it allows participants to demonstrate the efficacy of their implementation of peptide related impurity identification and quantification. The assessment of the mass fraction of peptide impurities is based on the assumption that only the most exhaustive and

    Résumé Objectif Faire un résumé clinique des lignes directrices canadiennes sur la rhinosinusite bactérienne aiguë (RSBA) qui présente des éléments d’intérêt pour les médecins de famille. Source des données Les auteurs des lignes directrices ont effectué une recherche documentaire systématique et ont rédigé des recommandations. Une cote a été donnée à la fois en fonction de la fiabilité des données probantes et de la solidité des recommandations. On a sollicité les commentaires d’experts en la matière venant de l’extérieur, ainsi que l’aval de sociétés médicales canadiennes (Association pour la microbiologie médicale et l’infectiologie Canada, Société canadienne d’allergie et d’immunologie clinique, Société canadienne d’otorhinolaryngologie et de chirurgie cervicofaciale, Association canadienne des médecins d’urgence et Regroupement canadien des médecins de famille en santé respiratoire). Message principal Le diagnostic de la RSBA repose sur la présence de symptômes particuliers et leur durée; l’imagerie ou une culture n’est pas nécessaire dans les cas peu compliqués. Le traitement dépend de la gravité des symptômes, notamment avec des corticostéroïdes intranasaux (CSIN) recommandés comme monothérapie pour les cas de légers à modérés, quoique leurs bienfaits soient modestes. Le recours à des CSIN accompagnés d’antibiotiques est réservé aux patients qui ne répondent pas aux CSIN après 72 heures et comme traitement initial des patients dont les symptômes sont graves. Le choix de l’antibiotique doit tenir compte du pathogène soupçonné, du risque de résistance, des problèmes concomitants et des tendances locales de la résistance aux antimicrobiens. Des thérapies d’appoint comme l’irrigation nasale avec une solution saline sont recommandées. En présence de cas réfractaires au traitement, d’épisodes récurrents et de signes de complications, on devrait demander une

    2013-01-01

    Under the auspices of the Organic Analysis Working Group (OAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM) a key comparison, CCQM-K81 'Chloramphenicol in pig muscle', was coordinated by BVL and PTB in 2009/2010. Six NMIs/DIs participated in this comparison. Chloramphenicol (CAP) is an effective broad-spectrum antibiotic which can in principle be used for the treatment of humans and animals. Its use for the treatment of food-producing animals is, however, forbidden worldwide in many countries due to potential severe side effects. The key comparison was the follow-up to the successful pilot study 'CCQM-P90: chloramphenicol in milk'. With this key comparison it was intended to demonstrate the capability of NMIs/DIs to analyse traces of CAP in food at concentration levels resulting from legal requirements for food control. Additionally, the quality of this kind of analysis with respect to compliance with legal requirements for food control methods and the international comparability of measurements should be evaluated in general. The study was classified as a 'track C' study (studies in emerging areas of global interest). For the study incurred lyophilised pig muscle material containing CAP (at a mass-fraction level around the maximum allowable level for import for a number of countries) has been produced as a candidate reference material by BVL and IRMM (Institute for Reference Materials and Measurements, JRC of the European Commission). Animal treatment and slaughtering of the animal to gain incurred muscle material as well as pre-testing of the CAP content was done at the BVL. The IRMM did further processing of the material and testing of homogeneity and stability. Participants were invited to assign the mass fraction of free CAP in the comparison sample. CCQM-K81 demonstrated successfully the capability of the participating laboratories to assign chloramphenicol values in tissue down to residue levels of around 0.3 ng/g (referring to the

    Houde, Martin

    2001-12-01

    Ce travail est une étude du champ magnétique duns l'environnement circumstellaire des étoiles jeunes. Il a pour origine la certitude qu'avait l'auteur qu'il se devait d'être possible de détecter la présence d'un champ magnétique, et de possiblement le caractériser, par le biais d'observations de profils spectraux d'espèces moléculaires ioniques. Il en découle donc qu'un des buts principaux était de prouver que cela est effectivement possible. La thèse comporte alors des éléments théoriques et expérimentaux qui sont à la fois complémentaires et intimement liés. L'aspect théorique est basé sur l'interaction mutuelle que des particules neutres et chargées peuvent avoir l'une sur l'autre daps un plasma faiblement ionisé comme ceux existants daps les nuages moléculaires sites de formation stellaire. Il appert que la présence d'un champ magnétique a un effet direct sur le comportement des ions (via la force de Lorentz) et indirect sur les molécules neutres (via les nombreuses collisions entre les deux types de particules). Une telle interaction est, comme il est maintenant bien connu, présente dans les premières étapes de la formation dune étoile. Il s'agit bien sûr de la diffusion ambipolaire. Nous montrerons qu'il existe cependant un autre type de diffusion, jusqu'ici inconnue, qui se manifeste plus tard au tours de l'évolution des nuages moléculaires. Celle-ci peut avoir un effet dramatique sur l'apparence des profils spectraux (de rotation moléculaire) des espèces ioniques lorsque comparés à ceux qu'exhibent des espèces neutres coexistantes. Mais pour ce faire, il doit y avoir existence de mouvements organisés (des flots ou jets) de matière ou encore la présence de turbulence dans les régions considérées. Une distribution de vélocité du type maxwellienne ne révèlera pas la présence du champ magnétique. Les observations, qui ont pour but de confirmer la théorie, se situent dans le domaine des longueurs d

    NASA Astrophysics Data System (ADS)

    Bredin, Nathalie

    La génération incéssante de déchets nécessite le développement de nouvelles technologies, telle que la valorisation énergétique, pour en disposer. Une filière appropriée pour valoriser énergétiquement les déchets est le procédé cimentier. L'industrie du ciment est une des grandes consommatrices d'énergie. La température nécessaire à la préparation du ciment se situe aux environs de 1450°C pour faire réagir la matière première (cru) qui est sous forme poudreuse et constituée principalement de roches calcaires, argileuses, schisteuses,... Les gaz de combustion ont un long temps de résidence dans les fours. De plus, le mode de fonctionnement des fours est responsable d'un effet de lessivage des gaz acides par le cru alcalin. Ces propriétés font du procédé cimentier un bon candidat pour la valorisation énergétique des déchets. Les déchets interessants pour les cimenteries sont, entre autres, les huiles usées, les solvants usés et les pneus usés qui ont un pouvoir calorifique équivalent à celui du charbon. Les rejets à l'atmosphère des cimenteries sont principalement des émissions gazeuses. Ainsi, l'impact de la valorisation de pneus usés sur les émissions gazeuses de la cimenterie Saint-Laurent de Joliette a été étudié, à l'aide de l'outil qu'est la modélisation de la dispersion atmosphérique. Le modèle utilisé ISC-ST2, Industrial Source Complex-Short Term, est de type gaussien. L'analyse des concentrations maximales horaires et moyennes sur différentes périodes de temps (1 heure, 8 heures, ..., 1 an) des émissions gazeuses dans l'air ambiant montre que celles-ci sont en deçà des normes émises par le gouvernement québécois et par la Communauté Urbaine de Montréal. L'étude de la distribution géographique des polluants, d'après les concentrations annuelles, dans un rayon de 5 km autour de la cimenterie montre que le fait d'utiliser des pneus comme combustible de substitution n'a qu'un faible impact sur la

    NASA Astrophysics Data System (ADS)

    Alcocer, Javier; Lugo, Alfonso; Marín, Luis E.; Escobar, Elva

    Waters from five cenotes that are currently being used for aquatic recreational activities and that lie along the Cancun-Tulum touristic corridor, Mexico, were evaluated hydrochemically to determine whether the cenotes may be considered as potential drinking-water sources. Several parameters exceed the Mexican Drinking Water Standards (MDWS), but since they do not pose a significant health threat, four of the five cenotes may be used as drinking-water sources. The common contaminants in the Yucatan Peninsula, fecal coliforms and nitrate, are in most cases below the MDWS (0-460 MPN/100ml and 0.31-1.18mg/L, respectively). Although these four cenotes meet the MDWS, a careful groundwater management policy needs to be developed to avoid contamination (fecal and nitrates) and salt-water intrusion. Résumé Les eaux de cinq cénotés, qui sont normalement utilisées pour des activités de plein air, dans la région touristique de Cancun-Tulum (Mexique), ont été soumises à analyses chimiques pour savoir si les cénotés peuvent être considérés comme des sources d'eau potable. Plusieurs paramètres dépassent les normes mexicaines en matière d'eau potable; mais comme ceux-ci ne posent pas de problème réel de santé, quatre des cinq cénotés peuvent être captés pour l'eau potable. Les contaminants habituels dans les eaux de la presqu'île du Yucatan, coliformes fécaux et concentrations élevées en nitrate, sont la plupart du temps au-dessous des normes (respectivement 0 à 460 germes/100ml et 0,31 à 1,18mg/l). Bien que ces quatre cénotés satisfassent aux normes, il est nécessaire de mettre en place des règles précises de l'utilisation de l'eau souterraine, afin d'éviter la contamination par les germes fécaux et par les nitrates, ainsi que l'intrusion marine. Resumen Se analizó hidroquímica y bacteriológicamente el agua de algunos cenotes localizados a lo largo del corredor turístico Cancun-Tulum, que actualmente se utilizan para diversas actividades

    2016-08-01

    To construct a census of the circumstellar disks in Taurus, we begin by compiling a list of all known members of the region. We adopt the 352 members from Luhman et al. 2010 (cat. J/ApJS/186/111), 4 additional stars that have good evidence of membership from previous studies (Section 5.4), 32 members found in a subsequent survey by K. Luhman (in preparation; 33 if GZ Tau A and B are counted separately), and 25 new members (26 if BS Tau A and B are counted separately) that we have confirmed with spectroscopy (Section 5.3). We also adopt as a member HD 285957, which has a proper motion consistent with that of the Taurus subgroup L1551 (Zacharias et al. 2013, cat. I/322; Luhman et al. 2009ApJ...703..399L) and exhibits evidence of youth in the form of Li absorption (Wichmann et al. 2000A&A...359..181W; Sestito et al. 2008, cat. J/A+A/488/943). We make use of mid-infrared photometry for members of Taurus measured with Spitzer's Infrared Array Camera (IRAC) and the Multiband Imaging Photometer for Spitzer (MIPS). We consider the four bands of IRAC (3.6, 4.5, 5.8, and 8.0μm) and the 24μm band of MIPS, which are denoted as [3.6], [4.5], [5.8], [8.0], and [24], respectively. IRAC produced images with a field of view of 5.2'*5.2' and FWHM of 1.6''-1.9'' for [3.6] to [8.0]. MIPS had a field of view of 5.4'*5.4' and a FWHM of 5.9'' for [24]. Photometry from most Spitzer images for most members of Taurus has been measured by Luhman et al. 2010 (cat. J/ApJS/186/111) (see also Hartmann et al. 2005ApJ...629..881H; Luhman et al. 2006, cat. J/ApJ/647/1180; Guieu et al. 2007, cat. 2007A&A...465..855G; Rebull et al. 2010, cat. J/ApJS/186/259). We have measured photometry of the members that were not considered in Luhman et al. 2010 (cat. J/ApJS/186/111) and all known members appearing in Spitzer images that have become publicly available since that study (Astronomical Observation Requests 26470912, 26471168 26477056, 26475264, 26472704, 26473216, and 23272448).

  3. Estimation of groundwater recharge using the chloride mass-balance method, Pingtung Plain, Taiwan

    NASA Astrophysics Data System (ADS)

    Ting, Cheh-Shyh; Kerh, Tienfuan; Liao, Chiu-Jung

    Due to rapid economic growth in the Pingtung Plain of Taiwan, the use of groundwater resources has changed dramatically. Over-pumping of the groundwater reservoir, which lowers hydraulic heads in the aquifers, is not only affecting the coastal area negatively but has serious consequences for agriculture throughout the plain. In order to determine the safe yield of the aquifer underlying the plain, a reliable estimate of groundwater recharge is desirable. In the present study, for the first time, the chloride mass-balance method is adopted to estimate groundwater recharge in the plain. Four sites in the central part were chosen to facilitate the estimations using the ion-chromatograph and Thiessen polygon-weighting methods. Based on the measured and calculated results, in all sites, including the mountain and river boundaries, recharge to the groundwater is probably 15% of the annual rainfall, excluding recharge from additional irrigation water. This information can improve the accuracy of future groundwater-simulation and management models in the plain. Résumé Du fait de la croissance économique rapide de la plaine de Pingtung à Taiwan, l'utilisation des ressources en eau souterraine s'est considérablement modifié. La surexploitation des aquifères, qui a abaissé le niveau des nappes, n'affecte pas seulement la région côtière, mais a de sérieuses répercutions sur l'agriculture dans toute la plaine. Afin de déterminer les ressources renouvelables de l'aquifère sous la plaine, une estimation précise de la recharge de la nappe est nécessaire. Dans cette étude, le taux de recharge de la nappe a d'abord été estimé au moyen d'un bilan de matière de chlorure. Quatre sites de la partie centrale ont été sélectionnés pour réaliser ces estimations, à l'aide d'un chromatographe ionique et de la méthode des polygones de Thiessen. A partir des résultats mesurés et calculés, à chaque site, et en prenant comme limites les montagnes et les rivi

    Desrosiers, Marc

    La Gaspésie, région péninsulaire à l'extrême est du Québec, possède un héritage archéologique préhistorique riche qui s'étend de 9 000 ans jusqu'à 450 ans avant aujourd'hui. L'archéologie a livré de nombreux sites préhistoriques dans la région, surtout dans le nord de la péninsule, un constat en partie attribuable à la présence de sources de matières premières lithiques, d'axes de circulation potentielles, mais aussi à la répartition spatiale inégale des efforts de recherche. L'étude du potentiel archéologique préhistorique gaspésien, c'est la première étape de la démarche archéologique, est donc nécessaire pour orienter les travaux futurs dans cette région. Trois secteurs représentatifs de la Gaspésie ont été étudiés pour développer une nouvelle approche d'étude de potentiel : Sainte-Anne-des-Monts, le lac Sainte-Anne et New Richmond. Ensemble, ces secteurs s'étirent au travers de la péninsule sur un axe nord-sud et correspondent à un possible axe de circulation préhistorique. L'évaluation du potentiel archéologique de ces aires d'étude dépend notamment de contexte géographique gaspésien. Celui-ci est complexe, particulièrement depuis la déglaciation qui a engendré une succession de transformations du paysage. Les variations du niveau marin relatif, le passage de la toundra à un milieu forestier et d'autres changements environnementaux ont conditionné la façon dont les populations préhistoriques se sont adaptées au territoire. L'étude de potentiel dépend également des connaissances archéologiques existantes pour la région, car elles conditionnent la sélection de variables environnementales représentatives des sites connus. À partir de la confrontation des données géographiques et archéologiques, nous avons proposé des schèmes d'établissement pour les périodes chronoculturelles de la préhistoire gaspésienne. Ces patrons informationnels permettent d'illustrer la façon dont les populations

    after the Phase 1 to Phase 2 review in favor of studying the slurry-form of AB as it appeared to be difficult to transport a solid form of AB through the thermolysis reactor. UTRC demonstrated the operation of a compact GLS in the laboratory at a scale that would be required for the actual automotive application. The GLS met the targets for weight and volume. UTRC also reported about the unresolved issue associated with the high vapor pressure of fluids that could be used for making a slurry-form of AB. Work on the GLS was halted after the Phase 2 to Phase 3 review as the off-board regeneration efficiency of the spent AB was below the DOE target of 60%. UTRC contributed to the design of an adsorbent-based hydrogen storage system through measurements of the thermal conductivity of a compacted form of Metal Organic Framework (MOF) number 5 and through the development and sizing of a particulate filter. Thermal conductivity is important for the design of the modular adsorbent tank insert (MATI), as developed by Oregon State University (OSU), in order to enable a rapid refueling process. Stringent hydrogen quality requirements can only be met with an efficient particulate filtration system. UTRC developed a method to size the particulate filter by taking into account the effect of the pressure drop on the hydrogen adsorption process in the tank. UTRC raised awareness about the potential use of materials-based H2 storage systems in applications outside the traditional light-duty vehicle market segment by presenting at several conferences about niche application opportunities in Unmanned Aerial Vehicles (UAV), Autonomous Underwater Vehicles (AUV), portable power and others.« less

    tous les adultes de 18 à 64 qui prennent un BZRA depuis plus de 4 semaines. Ces recommandations visent les patients qui prennent un BZRA contre l’insomnie seule (insomnie primaire) ou l’insomnie comorbide lorsque les comorbidités sous-jacentes sont efficacement prises en charge. Ces lignes directrices ne visent pas les personnes atteintes d’autres troubles non traités du sommeil ou d’anxiété, de dépression, ou d’autres troubles physiques ou de santé mentale pouvant causer ou aggraver l’insomnie. Conclusion Les agonistes des récepteurs des benzodiazépines sont liés à des torts, et leur effet thérapeutique serait bref. La réduction graduelle de la dose de BZRA améliore le taux d’abandon comparativement aux soins habituels, et ce, sans causer de torts graves. Les patients seraient plus ouverts à une conversation sur la déprescription s’ils comprennent le pourquoi (potentiel de torts), participent à l’élaboration du plan de réduction de la dose et reçoivent des conseils en matière de comportement. Les présentes lignes directrices émettent des recommandations pour décider du moment et de la façon de réduire la dose de BZRA pour mettre fin au traitement. Elles visent à contribuer au processus de décision conjointement avec le patient et non à le dicter. PMID:29760269

    Clusters of galaxies: a review After having briefly described the 3 main components of clusters of galaxies (dark matter, gas and galaxies) we shall present clusters from a theoretical viewpoint: they are the largest entities known in the universe. Consequently, clusters of galaxies play a key role in any cosmological study and thus, are essential for our global understanding of the universe. In the general introduction, we shall outline this fundamental aspect, showing how the study of clusters can help to constrain the various cosmological scenarios. Once this cosmological framework is set, the next chapters will present a detailed analysis of cluster properties and of their cosmic evolution as observed in different wavebands mainly in the optical (galaxies), X-ray (gas) and radio (gas and particles) ranges. We shall see that the detailed study of a cluster is conditioned by the study of the interactions between its different components; this is the necessary step to ultimately derive the fundamental quantity which is the cluster mass. This will be the occasion to undertake an excursion into extremely varied physical processes such as the multi-phase nature of the intra-cluster medium, lensing phenomena, starbursts and morphology evolution in cluster galaxies or the interaction between the intra-cluster plasma and relativistic particles which are accelerated during cluster merging. For each waveband, we shall outline simply the dedicated observing and analysis techniques, which are of special interest in the case of space observations. Finally, we present several ambitious projects for the next observatory generation as well as their expected impact on the study of clusters of galaxies. Après avoir brièvement décrit les 3 constituants fondamentaux des amas de galaxies (matière noire, gaz et galaxies) nous présenterons les amas d'un point de vue plus théorique : ce sont les entités les plus massives à l'équilibre connues dans l'univers.

    Le phénomène de perte de masse joue un rôle essentiel dès les premières étapes de la formation stellaire et semble être intimement lié à l'accrétion de matière sur l'étoile, probablement par l'intermédiaire de champs magnétiques permettant de convertir l'énergie cinétique accrétée, en puissance d'éjection. Les étoiles T Tauri classiques, âgées de quelques millions d'années et présentant une faible extinction, offrent un excellent cadre pour étudier les régions internes des vents stellaires. Dans ce travail, je présente les premières études sur la morphologie des jets associés aux étoiles DG Tau, CW Tau et RW Aur à une résolution angulaire de 0.1'' et sur la cinématique à deux dimensions de l'émission des raies de [O I]?6300Å, [N II]?6583Å et [S II] ?6716,6731Å dans le jet de DG Tau. Ces données ont été obtenues avec deux techniques d'observation complètement nouvelles, devenues disponibles entre 1994 et 1998 au télescope CFH, et idéalement adaptées à ce problème: l'imagerie en bande étroite derrière l'optique adaptative (PUEO) qui fournit des données à très haute résolution angulaire (~0.1''), et la spectro-imagerie intégrale de champ (TIGRE/OASIS) qui donne accès à l'information spatiale et spectrale à 2D, à haute résolution angulaire (ici ~0.5''-0.75'') et moyenne résolution spectrale (100-170 km/s). Les trois jets étudiés, résolus pour la première fois à partir de 55 u.a. de l'étoile, présentent une largeur similaire (30-35 u.a.) jusqu'à 100 u.a. et une morphologie dominée par des noeuds d'émission. Les jets des étoiles à faible excès infrarouge CW Tau et RW Aur sont très similaires aux deux autres jets des sources peu enfouies observés jusqu'à présent à la même échelle spatiale. Le jet de DG Tau, plus perturbé que les deux autres, et provenant d'une source avec une enveloppe encore importante, est aussi très similaire au seul autre jet associé à une source encore enfouie r

    Under the auspices of the Protein Analysis Working Group (PAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM) a key comparison, CCQM-K115, was coordinated by the Bureau International des Poids et Mesures (BIPM) and the Chinese National Institute of Metrology (NIM). Eight Metrology Institutes or Designated Institutes and the BIPM participated. Participants were required to assign the mass fraction of human C-peptide (hCP) present as the main component in the comparison sample for CCQM-K115. The comparison samples were prepared from synthetic human hCP purchased from a commercial supplier and used as provided without further treatment or purification. hCP was selected to be representative of the performance of a laboratory's measurement capability for the purity assignment of short (up to 5 kDa), non-cross-linked synthetic peptides/proteins. It was anticipated to provide an analytical measurement challenge representative for the value-assignment of compounds of broadly similar structural characteristics. The majority of participants used a peptide impurity corrected amino acid analysis (PICAA) approach as the amount of material that has been provided to each participant (25 mg) is insufficient to perform a full mass balance based characterization of the material by a participating laboratory. The coordinators, both the BIPM and the NIM, were the laboratories to use the mass balance approach as they had more material available. It was decided to propose KCRVs for both the hCP mass fraction and the mass fraction of the peptide related impurities as indispensable contributor regardless of the use of PICAA, mass balance or any other approach to determine the hCP purity. This allowed participants to demonstrate the efficacy of their implementation of the approaches used to determine the hCP mass fraction. In particular it allows participants to demonstrate the efficacy of their implementation of peptide related impurity identification and quantification

Botanique de la diversité apporte de la valeur à l’homme par la séquestration du carbone, de l’air et de purification de l’eau, et le provisionnement des aliments sauvages et ethnomedicines. Ici, nous calculons la valeur de ethnomedicines botaniques dans une région de forêt de Madagascar, la zone protégée de Makira, en utilisant une méthode de substitution qui combine les coûts de remplacement et la modélisation des choix. Le bassin versant de Makira peut comprendre environ 0,8% de la diversité botanique mondiale et possède une valeur énorme à la fois dans sa capacité à fournir ethnomedicines botaniques à la population locale et en tant que source de nouveaux médicaments potentiellement pharmaceutiques pour la société dans son ensemble. Environ 241 espèces localement reconnus sont utilisés comme ethnomedicines, y compris 113 espèces d’agricoles ou de mauvaises herbes. Nous assimilé chaque traitement ethnomédicales à la valeur monétaire d’un traitement comparable pharmaceutique ajusté en fonction des préférences personnelles en matière d’efficacité perçue (plutôt que de l’équivalence médicament connu ou supposé). La valeur de l’avantage de ces ethnomedicines botaniques par individu est de $5,40 à 7.90 par année lors de l’utilisation de la valeur des produits pharmaceutiques malgaches fortement subventionnés et de $100,60 à 287,40 lors de l’utilisation de la valeur des produits pharmaceutiques américains. Utilisation de produits pharmaceutiques locales comme des substituts, la valeur par ménage est de $30.24 à 44.30 par an, équivalent à 43–63% du revenu médian des ménages annuelle, ce qui démontre leur importance locale.

    Ostiguy, Pierre-Claude

    Les matériaux composites sont de plus en plus utilisés en aéronautique. Leurs excellentes propriétés mécaniques et leur faible poids leur procurent un avantage certain par rapport aux matériaux métalliques. Ceux-ci étant soumis à diverses conditions de chargement et environnementales, ils sont suceptibles de subir plusieurs types d'endommagements, compromettant leur intégrité. Des méthodes fiables d'inspection sont donc nécessaires pour évaluer leur intégrité. Néanmoins, peu d'approches non destructives, embarquées et efficaces sont présentement utilisées. Ce travail de recherche se penche sur l'étude de l'effet de la composition des matériaux composites sur la détection et la caractérisation par ondes guidées. L'objectif du projet est de développer une approche de caractérisation mécanique embarquée permettant d'améliorer la performance d'une approche d'imagerie par antenne piézoélectriques sur des structures composite et métalliques. La contribution de ce projet est de proposer une approche embarquée de caractérisation mécanique par ultrasons qui ne requiert pas une mesure sur une multitude d'échantillons et qui est non destructive. Ce mémoire par articles est divisé en quatre parties, dont les parties deux A quatre présentant les articles publiés et soumis. La première partie présente l'état des connaissances dans la matière nécessaires à l'acomplissement de ce projet de maîtrise.

    NASA Astrophysics Data System (ADS)

    Chapelle, Francis H.

    Microbial processes affect the chemical composition of groundwater and the hydraulic properties of aquifers in both contaminated and pristine groundwater systems. The patterns of water-chemistry changes that occur depend upon the relative abundance of electron donors and electron acceptors. In many pristine aquifers, where microbial metabolism is limited by the availability of electron donors (usually organic matter), dissolved inorganic carbon (DIC) accumulates slowly along aquifer flow paths and available electron acceptors are consumed sequentially in the order dissolved oxygen >nitrate>Fe(III)>sulfate>CO2 (methanogenesis). In aquifers contaminated by anthropogenic contaminants, an excess of available organic carbon often exists, and microbial metabolism is limited by the availability of electron acceptors. In addition to changes in groundwater chemistry, the solid matrix of the aquifer is affected by microbial processes. The production of carbon dioxide and organic acids can lead to increased mineral solubility, which can lead to the development of secondary porosity and permeability. Conversely, microbial production of carbonate, ferrous iron, and sulfide can result in the precipitation of secondary calcite or pyrite cements that reduce primary porosity and permeability in groundwater systems. Les processus microbiologiques peuvent affecter la composition chimique de l'eau souterraine et les propriétés hydrauliques des nappes aussi bien dans les systèmes aquifères pollués que dans les systèmes indemnes de pollution. Les changements de chimisme des eaux qui se produisent dépendent de l'abondance relative des donneurs et des accepteurs d'électrons. Dans les aquifères non contaminés, où le métabolisme microbien est limité par la disponibilité des donneurs d'électrons (en général la matière organique), le carbone minéral dissous (CMD) s'accumule lentement le long des axes d'écoulement souterrain et les accepteurs d'électrons disponibles sont

La combinaison entre une concentration élevée en matières organiques, provenant de la recharge par les eaux usées domestiques, et la faible profondeur de la nappe a produit des conditions fortement réductrices dans le niveau supérieur et une mobilisation de l'arsenic. Un modèle analytique simple montre que les échelles de temps pour la drainance vers le bas, à partir de la surface au travers de l'imperméable supérieur vers l'aquifère semi-captif, sont de l'ordre de quelques dizaines d'années. Resumen. Muchas ciudades en el sur y sudeste de Asia carecen de sistemas de saneamiento, por lo que las aguas residuales urbanas son a menudo vertidas bien directamente al suelo o bien a canales de aguas superficiales. Esta práctica puede provocar la contaminación difusa de las aguas subterráneas someras. En Hat Yai, al sur de Tailandia, la percolación de aguas residuales urbanas ha producido un deterioro substancial de la calidad del acuífero somero sobre el que se sitúa la ciudad. Por ello, la mayor parte del suministro de agua potable se obtiene a partir de aguas subterráneas de acuíferos semiconfinados más profundos, localizados entre 30 y 50 m bajo la superficie. No obstante, el goteo desde el acuífero freático constituye una fracción importante de la recarga al acuífero profundo, hecho que tiene implicaciones en lo que respecta a la calidad del agua a largo plazo. Se presentan en este artículo los resultados de testigos de sondeos y de multi-piezómetros someros. El alto contenido en materia orgánica de las aguas urbanas, unido a la cercanía del nivel freático, ha producido la movilización de arsénico al crearse condiciones altamente reductoras.

Se ilustra la influencia de la heterogeneidad del medio y de la interferencia humana mediante acciones tales como la recuperación de terrenos en la llanura costera belga, donde, hacia el año 1200 D.C., se aprovechó un medio sometido a fluctuaciones mareales. La salinidad del acuífero, que fue invadido por agua salada, está siendo rebajada desde entonces.

    Groundwater is crucial for the livelihoods and food security of millions of people, and yet, knowledge formation in the field of groundwater has remained asymmetrical. While, scientific knowledge in the discipline (hydrology and hydrogeology) has advanced remarkably, relatively little is known about the socio-economic impacts and institutions that govern groundwater use. This paper therefore has two objectives. The first is to provide a balanced view of the plus and the down side of groundwater use, especially in agriculture. In doing so, examples are drawn from countries such as India, Pakistan, Bangladesh, China, Spain and Mexico—all of which make very intensive use of groundwater. Second, institutions and policies that influence groundwater use are analyzed in order to understand how groundwater is governed in these countries and whether successful models of governance could be replicated elsewhere. Finally, the authors argue that there is a need for a paradigm shift in the way groundwater is presently perceived and managed—from management to governance mode. In this attempt, a number of instruments such as direct regulation, indirect policy levers, livelihood adaptation and people's participation will have to be deployed simultaneously in a quest for better governance. L'eau souterraine est cruciale pour la survie et la sécurité alimentaire de plusieurs millions de personnes mais cependant la foramtion en matière d'eaux souterraines reste asymmétrique. Alors que la connaissance scientifique dans la discipline (hydrologie et hydrogéologie) a avancée de manière remarquable, on connaît peu de choses sur les impacts socio-économiques et les institutions qui gouvernent l'utilisation des eaux souterraines. Cet article a par conséquent deux objectifs. Le premier est d'assurer un point de vue balancé entre le côté positif et le côté négatif de l'utilisation de l'eau souterraine, spécialement en agriculture. De cette manière, des exemples d

    que des pratiques forestières non coordonnées sont susceptibles d'exacerber les crues. La recharge des nappes est affectée par la foresterie, surtout à cause de prélèvements plus importants de l'eau du sol par les arbres et à cause de la capacité accrue des sols forestiers à retenir de l'eau, conduisant à de plus fortes teneurs en matières organiques. Les taux de recharge sous les forêts peuvent être réduits d'un dixième par rapport à la prairie ou à la lande. La qualité de l'eau souterraine peut être affectée par une acidification accrue et par une nitrification sous les forêts, provoquées pour une part par une fixation des polluants atmosphériques par le couvert forestier et pour une autre part par un dépôt plus important d'une litière plus fortement acide. Les taux de recharge plus lente des nappes sous les forêts conduisent à des retards importants dans la manifestation de la détérioration de la qualité de l'eau souterraine. Resumen. Se han iniciado los planes para duplicar la proporción de terrenos reforestados en Irlanda hacia el año 2035. El plan, impulsado por fines económicos, ignora los impactos potenciales medioambientales de la silvicultura, y, en particular, los impactos a los recursos de aguas subterráneas y a su calidad. Puesto que el 25 % del agua potable en Irlanda es suministrada por medio de aguas subterráneas, dichos impactos son importantes. Las investigaciones de campo indican que la reforestación lleva a una reducción de la escorrentía de hasta un 20 %, fundamentalmente por la interceptación de la lluvia en las copas de los árboles, mientras que la deforestación tiene el impacto opuesto. Las implicaciones son tales que las prácticas forestales descoordinadas pueden aumentar enormemente el riesgo de inundaciones. También la recarga a los acuíferos se ve afectada por la reforestación, debido, sobre todo, al uso del agua del suelo por los árboles y a la mayor capacidad de retención de los suelos en

    panel. Les 282 répondants étaient des immigrés en Finland provenant de l'ancienne Union Soviétique nés entre 1961 et 1976. Les résultats suggèrent que l'adaptation de ces immigrants s'est développée favorablement. En huit ans, les répondants avaient amélioré leurs habiletés en finlandais sur le marché de travail. Aucune différence n'a été observée dans leurs niveaux de bien-être psychologique entre les deux évaluations. Parmi les trois dimensions de l'adaptation évaluées, l'adaptation socio-culturelle telle que mesurée par la capacité de comprendre, de parler, de lire et d'écrire le finlandais s'est avérée être le prédicteur le plus significatif des deux autres résultats à long-terme de l'adaptation de l'immigré (i.e., socio-économique et psychologique). Particulièrement, meilleure avait été la connaissance initiale du finlandais, meilleurs étaient leurs résultats de l'adaptation socio-économiques et psychologiques après 8 ans de résidence. Ces résultats démontrent l'importance des évaluations parallèles et longitudinales de différents résultats de l'adaptation de l'immigré pour mieux étudier quelles dimensions particulières de l'adaptation sont les plus critiques au début de l'acculturation en matière de la détermination du développement positif et de l'adaptation à long-terme de l'immigré. El estudio consistió en una investigación longitudinal sobre tres diferentes dimensiones de adaptación de inmigrantes a largo plazo (i.e. adaptación psicológica, sociocultural, socioeconómica) y la relación entre ellas en 8 años de seguimiento con los datos de grupo. Los 282 encuestados fueron inmigrantes en Finlandia procedentes de los países de la antigua Union Sovietica, nacidos entre 1961 y 1976. Los resultados sugieren que la adaptación de estos inmigrantes se desarrolló favorablemente.

De plus, le fait d’être un ancien fumeur a augmenté le risque d’admission hospitalière. CONCLUSIONS Cette étude est d’une importance particulière car ses implications s’élargissent à des collectivités à faibles revenus similaires et chez les réfugiés dans la région ainsi qu’ailleurs. Il est nécessaire que les responsables de la santé publique fassent un effort plus concerté pour cibler les personnes âgées comme groupe en vue d’interventions d’arrêt du tabagisme, d’autant plus que les avantages en matière de mortalité et de santé ont aujourd’hui été bien documentés. RESUMEN OBJETIVOS Investigar los tipos de hábito tabáquico en una población de personas ancianas, de bajos ingresos y determinar los factores pronósticos del abandono del hábito. Asimismo, se analizó la importancia del tabaquismo en relación con otros factores de riesgo de hospitalización. DISEÑO Los datos formaban parte de un estudio de salud urbana de 740 personas de ≥60 años de edad, en tres comunidades suburbanas de bajo estrato socioeconómico en Beirut, una de las cuales era un campo de refugiados. Se administró una entrevista estructurada que aportaba amplia información social y sanitaria. RESULTADOS La prevalencia global de fumadores fue de 28,1%. Casi la mitad de las personas ancianas había sido fumadora en algún momento y 44% habían abandonado el tabaquismo. Estas personas abandonaron el hábito tabáquico cuando tuvieron repercusiones negativas sobre su salud. La

Les informations hydrochimiques et isotopiques peuvent être utilisées pour interpréter l'origine et le mode de recharge des eaux souterraines, affiner l'estimation des temps de recharge et d' écoulements, déchiffrer les processus de réaction, apporter une meilleure information paléohydrogéologique et calibrer les modèles d'écoulement des eaux souterraines. Beaucoup de progrès ont besoin d'être réalisés pour obtenir des échantillons représentatifs. Des améliorations sont nécessaires dans l'interprétation des informations obtenues, et dans la construction et l'interprétation de modèles numériques utilisant des données hydrochimiques. La meilleure approches arsurément un processus itératif optimisé entre la collection de données de terrain et l'analyse, l'interprétation, et l'application d'outils de modélisation statistique, inverse et direct. Des avancées sont anticipées par les dans le demeine des études microbiologiques, dans la caractérisation des matières organiques naturelles, le marquage isotopique, les mesures de gaz dissous, les réactions cinétiques la compréhension des couplages. Une perspectives thermodynamique pourraient faciliter la comparaison et la compréhension des multiples processus physiques, chimiques et biologiques qui affectent les systèmes hydrogéologiques. La geoquímica ha contribuido significativamente al entendimiento de los sistemas de aguas subterráneas durante los últimos 50 años. Entre los avances históricos puede incluirse el desarrollo del concento de facies hidroquímicas, la aplicación de la teoría de equilibrio, investigación de los procesos oxidación-reducción, y datación con radiocarbono. Otros conceptos, herramientas y técnicas hidroquímicas han ayudado a esclarecer los

    irreversible processes are also relevant. Thermal processes like the training effect manifesting itself in changes in the hysteretic characteristics depending on magnetic history can lead to changes in the magnetic configurations. This section contains an increasing number of investigations of dynamics in exchange bias coupled bilayers, and in particular those of the intriguing asymmetric magnetization reversal in both branches of a hysteresis loop.

    ée. L'objectif de cet article est de présenter et de discuter les résultats cliniques de sept années de travail impliquant 2116 femmes traitées dans trois hôpitaux à travers le pays. Méthodes Il s'agit d'une étude de cohorte rétrospective utilisant des données extraites des dossiers médicaux de réparations de fistules menées de 2007 à 2013. Les données de l’étude ont été analysées au cours de la période allant d'avril à août 2014. Résultats La majorité des 2116 femmes qui ont subi une réparation chirurgicale avaient une fistule vésico vaginale (n = 2 045, 97%) et 3% avaient une fistule recto vaginale ou une combinaison des deux. Au total, 1748 (83%) femmes ont eu leur fistule refermée et sont devenues continentes d'urine immédiatement après la chirurgie. À la sortie, 1795 femmes (85%) avaient une fistule fermée et 1680 (79%) étaient sèches, c'est à dire qu'elles n'avaient plus de fuite d'urine et/ou de matières fécales. 115 (5%) femmes avaient toujours une incontinence résiduelle malgré la fermeture de la fistule. Le suivi à trois mois a été complété par 1663 (79%) femmes dont 1405 (84,5%) ont eu leur fistule fermée et 80% étaient continentes. 21% ont été perdues au suivi. Conclusion La réparation programmatique de routine de la fistule obstétricale dans les régions à faibles ressources peut donner de bons résultats. Toutefois, davantage d'efforts sont nécessaires pour remédier à la perte au suivi, maintenir les résultats et prévenir l'apparition et/ou la réapparition de fistules. Objetivos La fístula genital femenina continúa siendo una preocupación de salud pública en países en vías de desarrollo. Entre Enero 2007 y Septiembre 2013, el proyecto Fistula Care, manejado por EngenderHealth junto con el Ministerio de Salud de Guinea, y financiado por USAID, integró los servicios de reparación de fistula en las maternidades de hospitales generales en Guinea. El objetivo de este artículo es presentar y

    L'École Thématique “Structure et Dynamique des Systèmes Désordonnés” [1] s'inscrit dans le cadre des écoles organisées sous l'impulsion de la Société Française de la Neutronique (SFN). Elle s'est deroulée en mai 2002 sur la Presqu'île de Giens (Var) en première partie des 11émes Journées de la Diffusion Neutronique. L'Édition de ces cours constitue ainsi le cinquième ouvrage introduisant les techniques neutroniques et leurs apports à differentes thématiques [2]. Le désordre est un facteur déterminant pour pratiquement toutes les propriétés des matériaux. Il est inhérent dans les matériaux amorphes ou liquides, mais il détermine également les propriétés mécaniques et électroniques d'autres composés d'importance technologique comme les matériaux métalliques, dont l'aspect “désordonné” est moins évident. Le désordre enfin joue un rôle essentiel dans tout ce que touche à la vie. En fait, il est difficile d'imaginer des systèmes, à part quelques exceptions rares comme l'hélium ou le silicium de haute pureté, où il n'y ait pas de désordre. En dehors de cet aspect pratique, la description scientifique du désordre atomique pose toujours des problèmes fondamentaux faute de concepts pertinents. Une des tâches importantes du scientifique ou de l'ingenieur est de préciser quel genre de désordre existe à une échelle d'espace et de temps donnée. Un materiau peut très bien être homogène à l'échelle atomique et présenter des défauts ou des hétrogéneité visibles à l'œil et inversement. De même, un système désordonné à un instant donné, peut apparaître ordonné si on moyenne dans le temps. Les techniques de diffusion des neutrons sont idéales pour aborder ces questions. Les neutrons sondent directement les noyaux et ont à la fois des longueurs d'ondes proches des distances inter atomiques et des énergies avoisinant celles des excitations élémentaires de la matière condensée. Ils permettent ainsi

    ère sur onduleurs et 22 sur aimants de courbure. Les premiers “utilisateurs” sont prévus au printemps 2006 avec couverture de l'IR jusqu'aux X durs pour des études variées notamment dans le domaine de la matière condensée. - La LIL (ligne d'intégration laser) du LMJ fonctionne avec 4 faisceaux (de 30 kJ à 351 nm) et un ensemble de diagnostics plasma est en cours de validation (énergie, imagerie X, spectrométrie X). Un souci d'ouverture collaborative (France et étranger) est affiché. - LASERIX (LIXAM, LOA) a pour but de doter les scientifiques français d'un laser émettant en “quasi-routine” de l'émission laser X à 6 tirs/mn basée sur différents schémas collisionnels et donc différentes longueurs d'ondes, et mettant en oeuvre un laser saphir-titane ultra bref de 40 J pour la génération plasma. - Le projet Arc en Ciel (CEA, LOA) se penche sur la possibilité de mise en oeuvre d'une source de “4^ogénération”. Ces sources se veulent à la fois brillantes, cohérentes, dans la gamme des 100 femtosecondes, ce qui conduit à tourner le dos aux anneaux de stockage pour se focaliser sur la combinaison accélérateur linéaire/onduleur, complétée par un laser saphir-titane (génération d'harmoniques UV/X dans des gaz). - Une avancée particulièrement intéressante a été récemment réalisée, notamment au LOA, par injection d'un laser X (plasma) par un faisceau X de bonne qualité (polarisation, divergence, temps, contraste...) issu de la génération d'harmoniques élevées par une chaîne saphir-titane femto. - On notera aussi les avancées réalisées dans le domaine des sources incohérentes de forte intensité dans le domaine des X par interaction optimisée de l'interaction laser de puissance-agrégats (GPS-Paris 6 et 7, CEA Saclay), ainsi que par techniques X-pinch à fils à foyer de 10 microns (LPTP-École Polytechnique). - La génération d'harmoniques d'ordres élevés à partir de chaînes laser amplifiées a continué à faire l

    nombres leptoniques partiels. Dans la plupart des extensions du modèle standard on met en évidence plusieurs mécanismes de conversion d'un lepton en un lepton d'une autre famille, avec comme conséquences expérimentales : les désintégrations μ → e γ , μ → e γ γ et μ → e e e la conversion muon-électron dans un noyau, les oscillations de neutrinos. La possibilité d'obtenir une résonance lors de l'oscillation des neutrinos dans la matière a des conséquences importantes pour l'astrophysique. En principe, l'isospin n'était pas au menu du cours, puisque traité par un autre professeur. On a cependant ajouté, à la demande de l'éditeur, un chapitre sur les expériences recherchant une violation de la symétrie de charge dans les forces nucléaires (chapitre 10).
