In this work we present experimental results on the behavior of diamond at megabar pressure. The experiment was performed using the PHELIX facility at GSI in Germany to launch a planar shock into solid multi-layered diamond samples. The target design allows shock velocity in diamond and in two metal layers to be measured as well as the free surface velocity after shock breakout. As diagnostics, we used two velocity interferometry systems for any reflector(VISArs). Our measurements show that for the pressures obtained in diamond(between 3 and 9 Mbar),the propagation of the shock induces a reflecting state of the material. Finally, the experimental results are compared with hydrodynamical simulations in which we used different equations of state, showing compatibility with dedicated SesAME tables for diamond.

The GrAAL experimental set-up consists of a polarized and tagged photon beam that covers an energy range from a minimum of 600 MeV up to a maximum of 1500 MeV, of a liquid Hydrogen or Deuterium target and of the 4π Lagrange detector optimized for photon detection. It allows the study of pseudo-scalar and vector meson photoproduCtion on the nucleon in the energy range corresponding to the second and the third resonance regions. In the following, the ∑ beam asymmetries in η and π0 photoproduction on quasi-free nucleon are shown. Also single and double polarization observables in K＋A photoproduction on free proton are shown; they are important to confirm the role of new or poorly known resonances in the 1900 MeV mass region.

Healthcare-Associated bacteremia and Urinary Tract Infections in Wards A and b of Medicine Department, CNHU-HKM of Cotonou: Characteristics and risk Factors

引用

Open Journal of Internal Medicine 2018年第1期8卷 42-53页

作者： Angèle Azon-Kouanou Kouessi Anthelme Agbodande Faridath Abèni Tatiane Massou Dissou Affolabi roberto Dossou torès Kouassi Prudencio Carin Ahouada Komi Habada Murhula Katabana Delphin Djimon Marcel Zannou Fabien Houngbé Internal Medicine Department National Teaching Hospital Hubert Koutoukou Maga of Cotonou Bénin bacteriology-Virology Department National Teaching Hospital Hubert Koutoukou Maga of Cotonou Bénin

Introduction: Healthcare-associated infections are involved in hospital long-stay and in the increase in inherent costs to patients care. Objectives: Objective was to describe the characteristics of healthcare-associated bacteremia and urinary tract infections in medical wards of CNHU-HKM of Cotonou, describe the distribution of germs identified according to admission wards and identify factors associated with onset of healthcare-associated infections. Materials and Methods: It was a cohort study conducted from 4th April to 16th September 2016. The study population included patients admitted in wards A and b of CNHU-HKM Medicine department for at least the past 48 hours, or readmitted in one of the medical wards less than 14 days after their discharge from hospital. results: The study included 825 patients in total. Prevalence of healthcare-associated infections was 9.8%. bacteremia was the most represented group (65.4%). The most often identified germs regardless of the site were respectively: K. pneumonia (38.5%), S. aureus (23.1%) and E. coli (20.0%). HIV+ status, internal medicine department, nephrology and endocrinology, duration of admission and the use of urinary catheter represent factors statistically associated with the onset of healthcare-associated infections. Conclusion: Healthcare-associated infections are a real public health issue in CNHU-HKM Medicine Department. There is pressing need to conduct a study on clinical hygiene so as to assess healthcare staff in practice.

The energy spectrum of cosmic Hydrogen and Helium nuclei has been measured below the so-called ＂knee＂ by using a hybrid experiment with a wide field-of-view Cherenkov telescope and the resistive Plate Chamber （rPC） array of the ArGO-YbJ experiment at 4300 m above sea level. The Hydrogen and Helium nuclei have been well separated from other cosmic ray components by using a multi-parameter technique. A highly uniform energy resolution of about 25% is achieved throughout the whole energy range （100-700 TeV）. The observed energy spectrum is compatible with a single power law with index γ=-2.63±0.06.

The product of the ∧0/b （-b/0） differential production cross-section and the branching fraction of the decay ∧0/b→ J/ψ pK-（-b/0→ J/ψ-K＊（892）0）is measured as a function of the beauty hadron transverse momentum, PT, and rapidity, y. The kinematic region of the measurements is pT〈20 GeV/c and 2.0 〈g〈*** measurements use a data sample corresponding to an integrated luminosity of 3fb-1 collected by the LHCb detector in pp collisions at centre-of-mass energies √s=7 TeV in 2011 and √s=8 TeV in 2012. based on previous LHCb results of the fragmentation fraction ratio,f∧0/b/fd,the branching fraction of the decay ∧0/b→ J/ψ pK-is measured to be b（∧0/b→ J/ψ pK-）=（3.17±0.04±0.07±0.34＋0.45/-0.28）×10-4,where the first uncertainty is statistical, the second is systematic, the third is due to the uncertainty on the branching fraction of the decay -b/0 →J/ψ-K＊（892）0,and the fourth is due to the knowledge of f∧0/b/*** sum of the asymmetries in the production and decay between ∧0/b and ∧0/bis also measured as a function of PT and *** previously published branching fraction of ∧0/b→ J/ψ pπ-,relative to that of ∧0/b→ J/ψ pK-,is updated. The branching fractions of ∧0/b→P＋c（→ J/ψp）K-are determined.
