Abstract

Neutron-rich isotopes around lead, beyond N = 126, have been studied exploiting the fragmentation of an uranium primary beam at the FRS-RISING setup at GSI. For the first time beta-decay half-lives of Bi-219 and Tl-211,Tl-212,Tl-213 isotopes have been derived. The half-lives have been extracted using a numerical simulation developed for experiments in high-background conditions. Comparison with state of the art models used in r-process calculations is given, showing a systematic underestimation of the experimental values, at variance from close-lying nuclei.

Abstract

International audience; The isospin mixing was deduced in the compound nucleus Zr-80 at an excitation energy of E* = 54 MeV from the gamma decay of the giant dipole resonance. The reaction Ca-40 + Ca-40 at E-beam = 136 MeV was used to form the compound nucleus in the isospin I = 0 channel, while the reaction Cl-37 + Ca-44 at E-beam = 95 MeV was used as the reference reaction. The. rays were detected with the AGATA demonstrator array coupled with LaBr3:Ce detectors. The temperature dependence of the isospin mixing was obtained and the zero-temperature value deduced. The isospin-symmetry-breaking correction delta(C) used for the Fermi superallowed transitions was extracted and found to be consistent with beta-decay data.

Abstract

F.C.L. Crespi et al.; 9 pags.; 9 figs.; PACS number(s): 24.30.Cz, 24.10.Eq, 25.70.Bc, 27.60.+j, © 2015 American Physical Society. 2+ and 1- states in Zr90 were populated via the (O17,O′17γ) reaction at 340 MeV. The γ decay was measured with high resolution using the AGATA (advanced γ tracking array demonstrator array). Differential cross sections were obtained at few different angles for the scattered particle. The results of the elastic scattering and inelastic excitation of 2+,3-, and 1- states are compared with distorted-wave Born approximation (DWBA) calculations, using both the standard collective form factor and a form factor obtained by folding microscopically calculated transition densities. This allowed to extract the isoscalar component of the 1- state at 6.424 MeV. The comparison of the present (O17,O′17γ) data with existing (γ,γ′) and (p,p′) data in the corresponding region of the γ continuum (6-11 MeV), characterized by a large E1 component, shows completely different behaviors of the cross section as a function of the nuclear excitation energy. The comparison of the data with DWBA calculations suggests a decrease of the isoscalar strength in the cross section with increasing excitation energy., We acknowledge support from several grants.

Abstract

F.C.L. Crespi et al. ; 5 pags. ; 4 figs. ; PACS numbers: 24.30.Cz, 24.10.Eq, 25.55.Ci, 27.80.+w, The properties of pygmy dipole states in Pb208 were investigated using the Pb208(O17, O17'γ) reaction at 340 MeV and measuring the γ decay with high resolution with the AGATA demonstrator array. Cross sections and angular distributions of the emitted γ rays and of the scattered particles were measured. The results are compared with (γ, γ′) and (p, p′) data. The data analysis with the distorted wave Born approximation approach gives a good description of the elastic scattering and of the inelastic excitation of the 2+ and 3- states. For the dipole transitions a form factor obtained by folding a microscopically calculated transition density was used for the first time. This has allowed us to extract the isoscalar component of the 1- excited states from 4 to 8 MeV. © 2014 American Physical Society., We acknowledge support from several grants.

Abstract

The gamma decay from Coulomb excitation of 68Ni at 600 MeV/nucleon on a Au target was measured using the RISING setup at the fragment separator of GSI. The 68Ni beam was produced by a fragmentation reaction of 86Kr at 900 MeV/nucleon on a 9Be target and selected by the fragment separator. The gamma rays produced at the Au target were measured with HPGe detectors at forward angles and with BaF2 scintillators at backward angles. The measured spectra show a peak centered at approximately 11 MeV, whose intensity can be explained in terms of an enhanced strength of the dipole response function (pygmy resonance). Such pygmy structure has been predicted in this unstable neutron-rich nucleus by theory.

Abstract

The population of 102Zr following the β decay of 102Y produced in the projectile fission of 238U at the GSI facility in Darmstadt, Germany has been studied. 102Y is known to ß decay into 102Zr via two states, one of high spin and the other low spin. These states preferentially populate different levels in the 102Zr daughter. In this paper the intensities of transitions in 102Zr observed are compared with those from the decay of the low-spin level studied at the TRISTAN facility at Brookhaven National Laboratory and of the high-spin level studied at the JOSEF separator at the Kernforschungsanlage Jülich.

Abstract

S-adenosyl-L-methionine (SAMe) is a physiological compound which plays an important role in numerous biological processes, such as transmethylations, transulphurations and aminopropylations. Starting from a study about the usefulness of the SAMe to normalize protein synthesis in old age, the drug was found to have an interesting action with respect to fibrinogen. Later research regarding a large number of patients, led us to discover after treatment for 40 days with 60 mg/die of SAMe, highly significant variations in fibrinogen values with constant normalization of this parameter, in both hypo- and hyper-fibrinogenemia. So far we don't know anything about the action of the drug on various metabolic stages of the fibrinogen; interestingly however our data exclude a rise in fibrinolysis.

Abstract

Several guidelines have recommended that antibiotic prophylaxis (AMP) should be given only at premedication, except in selected cases. Conversely, in clinical practice, AMP is often unnecessarily prolonged after the surgical procedure. In this observational study, we evaluated the risk of surgical site infection (SSI) associated with the prolongation of AMP after clean and clean-contaminated surgery.All consecutive patients who underwent a surgical procedure were eligible. AMP was always administered before the surgical incision. Prolongation of AMP for the first 24 hours was allowed only in presence of at least one risk factor for SSI: an ASA score2 or surgical procedure longer than the specific cutoff (as indicated by the NNIS--the National Nosocomial Infections Surveillance System). SSIs were evaluated during the hospital stay and after hospital discharge.Three hundred fifty-eight patients were enrolled; 19 (5.3%) and 17 (6.5%) patients developed respectively intra-hospital and post hospital discharge SSIs. AMP prolongation for 24 hours in patients with at least one risk factor did not reduce the risk for intra-hospital SSI (OR 1.102; 95% CI: 0.336-3.612; P=0.873), while it increased the risk in patients without risk factors (OR: 8.99; 95% CI: 1.46-55.4; P=0.018). AMP longer than 24 hours raised the risk for intra-hospital and post hospital discharge SSI, regardless of the presence of risk factors (OR: 3.39; 95% CI 1.11-10.35; P=0.032 and OR: 5.39; 95% CI: 1.64-17.75; P=0.006, respectively.)Postoperative AMP prolongation should be avoided.

Abstract

Neutron-deficient nuclei with N = 126 have been populated following projectile fragmentation of a 238U beam with energy 1 GeV/A. The decay of several previously reported isomers has been measured. This will allow us to calculate high-spin isomeric ratios and compare them with model calculations to allow a better understanding of the reaction mechanism.

Abstract

The reaction 48Ca+64Ni has been studied in the deep inelastic regime at approximately 6 MeV/A, by the CLARA-PRISMA setup. Angular distributions of the reaction cross sections have been obtained for the most intense reaction products, taking into account the response function of the magnetic spectrometer. The response of PRISMA has been calculated making use of a MonteCarlo simulation of the transport of the ions in the spectrometer, starting from known events distributions. For the one-nucleon transfer channels, the experimental data are in good agreement with predictions from a semiclassical multi-nucleon transfer model.

Abstract

The aim of this study was to evaluate the arterio-venous difference in carbon dioxide tension (DPCO2) and the ratio between DPCO2 and arterio-jugular oxygen difference (AJDO2) as indicators of compensated or uncompensated cerebral hypoperfusion.Cerebral blood flow (CBF) was reduced stepwise in 6 pigs by inducing intracranial hypertension with consequently cerebral perfusion pressure (CPP) reduction: CBF 100%, 50-60 % of baseline, 20-30% of baseline. Intracranial pressure (ICP), mean arterial pressure (MAP), CPP and CBF (laser-Doppler method) were continuously recorded. Superior sagittal sinus was punctured for the determination of AJDO2 and DPCO2.CBF impairment was accompanied by changes in AJDO2 from 6.03 +/- 1.21 vol% to 7.32 +/- 1.30 vol%, up to 8.07 +/- 1.32 vol% (P0.01), in DPCO2 from 12.17 +/- 3.25 mmHg to 16 +/- 4.12 mmHg, up to 26.5 +/- 6.41 mmHg (P0.01), and DPCO2/AJDO2 ratio from 2.05 +/- 0.39 to 2.06 +/- 0.72 up to 3.41 +/- 1.09 in the 3 phases (P0.05).When CBF declines AJDO2 increases, indicating greater extraction of O2 to satisfy aerobic metabolism. However, this mechanism can no longer compensate once a critical CBF threshold is reached. DPCO2 rises slowly during moderate CBF reduction because of defective washout; the rise is steeper during marked CBF impairment when anaerobic metabolism takes place. During cerebral hypoperfusion the venous blood gases and acid base variables mirror the degree of cerebral perfusion. In particular the DPCO2, and the DPCO2/ AJDO2 ratio may be useful markers of critical brain hypoperfusion.

Abstract

We analyze the impact on wages of the adoption of a rent-sharing remuneration scheme aimed at making labor institutions more flexible. We work within a quasi-experimental setting referring to a sample of Italian companies before and after the introduction of the Treu Reform (1997). Our estimations confirm that this reform not only increased insider workers' wages via rent-sharing, but also fueled a σ−convergence process of the rent-sharing elasticity across the sectors at a different rate. Finally, we deliver a reasoned discussion of the consequences of implementing this reform on the Italian job market. This reform produced advances in the quality of job remuneration but it deepened a structural gap in the Italian labor market composition.

Abstract

Pre-equilibrium emissions affect the production of excited systems in nuclear reactions, thus modifying their properties which enter as input parameters in the comparison with statistical models. In this contribution, we discuss this subject referring to recent results from experiments performed at Legnaro National Laboratories (Italy) with the GARFIELD apparatus complemented with other detectors. ispartof: Acta Physica Polonica B vol:48 issue:3 pages:635-639 ispartof: location:Zakopane: POLAND status: published
