Designing Outcome-Based Performance Management Systems to Assess Policies Impacting on Caesarean Section Rate: An Analysis of the Sicilian Maternity …

2017

The reduction in Caesarean sections (CSs) is widely considered a priority in the public decision makers agenda. Though the World Health Organisation has strongly encouraged countries to implement policies to reduce CSs to 10–15%, after almost thirty years this goal appears still far from its achievement. The literature depicts CS as a multifaceted phenomenon whose causes involve different factors, ranging from the patient sphere to the health care level of services provided, and the societal preference of CS practice. Policy makers aiming to standardise cares and to reduce CSs often implement maternity pathways (MP). By investigating the MP introduced in the Sicilian region, the authors hig…

Direkte Dickenmessung an Muskelstreifenpräparaten und Gewebsschnitten

1967

An apparatus for direct measurement of the thickness of tissue slices and muscle strips is described. Micrometer callipers are used, the proper adjustment of which is indicated by the sudden scale deflection of an ohmmeter. In comparison with the method of calculation based on a measurement of the area of the slice, this technique is time-saving and the results are more accurate and reproducible.

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at √s = 7 TeV with the ATLAS detector

2011

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton–proton collisions at a centre-of-mass energy of √s =7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb[superscript −1]. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the ra…

The A dependence of the nuclear structure function ratios

1996

Results are presented for six nuclei from Be to Pb on the structure function ratios F-2(A)/F-2(C)(X) and their A dependence in deep inelastic muon scattering at 200 GeV incident: muon energy. The data cover the kinematic range 0.01 < x < 0.8 with Q(2) ranging from 2 to 70 GeV2. The A dependence of nuclear structure function ratios is parametrised and compared to various models.

Thermal neutron capture cross sections of tellurium isotopes

2003

New values for thermal neutron capture cross sections of the tellurium isotopes 122Te, 124Te, 125Te, 126Te, 128Te, and 130Te are reported. These values are based on a combination of newly determined partial g-ray cross sections obtained from experiments on targets contained natural Te and gamma intensities per capture of individual Te isotopes. Isomeric ratios for the thermal neutron capture on the even tellurium isotopes are also given.

Photoproduction of π 0 mesons off protons and neutrons in the second and third nucleon resonance regions

2018

Photoproduction of mesons off quasi-free nucleons bound in the deuteron allows to study the electromagnetic excitation spectrum of the neutron and the isospin structure of the excitation of nucleon resonances. The database for such reactions is much more sparse than for free proton targets. Single $\pi^0$ photoproduction off quasi-free nucleons from the deuteron was experimentally studied. Nuclear effects were investigated by a comparison of the results for free protons and quasi-free protons and used as a correction for the quasi-free neutron data. The experiment was performed at the tagged photon beam of the Mainz MAMI accelerator for photon energies between 0.45~GeV and 1.4~GeV, using an…

German Registry for Acute Aortic Dissection Type A (GERAADA)--new software design, parameters and their definitions.

2011

BACKGROUND The working group for aortic surgery and interventional vascular surgery of the German Society for Thoracic and Cardiovascular Surgery (GSTCVS) initiated the web-based German Registry for Acute Aortic Dissection type A (GERAADA). It is the project's aim to collect standardized data from a large pool of patients with acute aortic dissections type A (AADA) to gain a deeper insight and knowledge to improve surgical therapies and perioperative management for these patients in the future. METHODS In addition to new medical insights, the working group has gained more experience over the last 4 years in how to collect valid and high-quality data. This experience led us to revise the dat…

BACKGROUND The aim of this study was to identify risk factors for surgical complications after anatomic lung resections in the era of video-assisted thoracic surgery (VATS) and enhanced recovery after surgery (ERAS). METHODS A retrospective analysis of all consecutive adult patients who underwent elective anatomic lung resections between January and December 2020 at our institution was performed. RESULTS Eighty patients (40 VATS, 40 thoracotomy) were included. The 30-day mortality rate was 1.3%. The overall rate of major postoperative complications was 18.8%. Most major complications occurred in patients who underwent open surgery (complication rate 32.5%, share of total complications 86.7%…

Inclusive dijet photoproduction in ultraperipheral heavy ion collisions at the CERN Large Hadron Collider in next-to-leading order QCD

2019

We compute the cross section of inclusive dijet photoproduction in ultraperipheral Pb-Pb collisions at the CERN Large Hadron Collider using next-to-leading order perturbative QCD. We demonstrate that our theoretical calculations provide a good description of various kinematic distributions measured by the ATLAS Collaboration. We find that the calculated dijet photoproduction cross section is sensitive to nuclear modifications of parton distribution functions (PDFs) at the level of 10% to 20%. Hence, this process can be used to reduce uncertainties in the determination of these nuclear PDFs, whose current magnitude is comparable to the size of the calculated nuclear modifications of the dije…
