ABSTRACT
Introduction
We conducted a randomized, double‐blind, placebo‐controlled trial to evaluate the effect of ultrasound‐guided corticosteroid injection in patients with ulnar neuropathy at the ...elbow (UNE).
Methods
Fifty‐five patients were randomized between an ultrasound‐guided injection of 1 ml containing 40 mg methylprednisolone acetate and 10 mg lidocaine hydrochloride or a placebo injection. The primary outcome was the subjective change of symptoms after 3 months. The secondary outcomes were change in electrodiagnostic studies and ultrasonography findings.
Results
A success rate of 30% was found in the corticosteroid injection group versus 28% in the placebo injection group. Only the nerve cross‐sectional area changed significantly in the intervention group, from a mean of 11.9 mm2 to 10.9 mm2.
Conclusions
We could not demonstrate a positive effect of ultrasound‐guided corticosteroid injection in UNE compared with placebo. Favorable outcomes may be attributed to the natural course of UNE or the effect of patient education. Muscle Nerve 52:380–385, 2015
A new segmented silicon-array called MUSETT has been built for the study of heavy elements using the Recoil-Decay-Tagging technique. MUSETT is located at the focal plane of the VAMOS spectrometer at ...GANIL and is used in conjunction with a γ-ray array at the target position. This paper describes the device, which consists of four 10×10cm2 Si detectors and its associated front-end electronics based on highly integrated ASICs electronics. The triggerless readout electronics, the data acquisition and the analysis tools developed for its characterization are presented. This device was commissioned at GANIL with the EXOGAM γ-ray spectrometer using the fusion–evaporation reaction 197Au(22Ne,5n)214Ac. Additionally, the performance of the VAMOS Wien filter used during the in-beam commissioning is also reported.
•Method to obtain wide ranges of water contact angles (CA) ∼5° to ∼149° proposed.•Reported effect of length of silicon nanowires and/roughness on final water CA.•Reported how nanoscale variation in ...PDMS thickness effects hydrophobic recovery.•Studied evolution of water CA vs. time for PDMS coated Si/Si nanowire samples.
The ability to modify the contact angle (CA) of water on silicon has applications ranging from thermal management of electronics to miniaturized biomedical devices. Here, we report ∼30±1° variation in superhydrophobic CA on silicon nanowires (NWs) coated with few nm of polydimethylsiloxane (PDMS), using a simple and stable plasma treatment. The variation in CA arises from choosing NWs of different lengths. We characterize the surfaces using a combination of X-ray photoelectron spectroscopy and other techniques. Together with CA available from similar treatment on bulk silicon, it is possible to non-lithographically create regions of diverse CA, from ∼5 to 149±1°.
A compact, quasi-

The Transfer and Inelastic ...All-angle Reaction Array (TIARA) consists of 8 resistive charge division detectors forming an octagonal barrel around the target and a set of double-sided silicon-strip annular detectors positioned at each end of the barrel. The detector was coupled to the

The first on-line production system for SPIRAL/GANIL (Radioactive Ion Production System with Acceleration on-Line) phase-I has been commissioned on the SIRa (Radioactive Ion Separator) test bench. ...Exotic multicharged noble gas ion beams have been obtained during several days. In parallel, a new ECRIS (Electron Cyclotron Resonance Ion Source) for monocharged ions has also been developed. Preliminary off-line results are presented.
The paper builds on a French-German comparison of how individuals' education and their social class position are related to each other. Labour-force surveys from the early 1970s and 1990s are used as ...the empirical basis. We analyse patterns of occupational stratification by education from three perspectives: change over time in each country, cross-national similarities and differences, and gender-specific variation. Focusing on the historical perspective, our analyses reveal substantial changes in each nation's pattern of occupational stratification by education. From the cross-national perspective, we observe France and Germany as countries where relatively strong education effects prevail compared with other countries. Despite a slight trend of convergence in some aspects over time, the exact patterns of occupational stratification by education, however, vary. They are highly structured by the institutional arrangements of the respective educational and employment settings. Due to gender-specific variation in the returns to education in the early 1970s, especially in Germany, we find the same pattern of cross-national dissimilarities in the link between education and social-class position for women as for men only in the early 1990B.
Production efficiencies of radioactive oxygen and nitrogen beams for the SPIRAL target-source system, measured at GANIL on the SIRa test bench, are presented. From the overall efficiency of oxygen, ...the product between the efficiency of transformation of O into CO and the effusion of CO from the target to the ion source, was deduced. The production yield measurements of oxygen and nitrogen isotopes performed on the SIRa test bench and those of fluorine directly measured on the SPIRAL facility are presented.

In the framework of the SPIRAL2 project at GANIL, the Super-Separator-Spectrometer (S.sup.3) is dedicated to experiments using the very high intensity stable beams (>10 pmicroA) delivered by the ...superconducting linear accelerator up to 14.5 A.MeV. Specific target stations are required to sustain these unprecedented beam intensities. A prototype target station for actinides was designed and manufactured, which main characteristics are described in this paper. In order to commission this system and check the behavior of target materials, preliminary tests with 7.7 A.MeV .sup.129Xe beams were performed at 100 pnA. The results of these tests are presented here.
