PURPOSE The authors recently used topical endoscopy to image the mouse eye fundus. Here, they widened the field of application for this ophthalmologic tool, imaging both the posterior and the anterior eye segments in larger animals commonly encountered in research laboratories and veterinary clinics. METHODS Pupils were dilated, and local anesthetic and(More)
Lower limb movements for clutch-pedal operations were investigated and the influence of four parameters (seat height, pedal travel, pedal travel inclination, pedal resistance) was studied using a multi-adjustable experimental seat. Fifteen subjects participated in the experiment: five short females, five average height males and five tall males. A(More)
Rotating plasma spheroids are observed in a capacitively-coupled radio-frequency (ccrf) discharge containing grown dust particles. These plasma spheroids are regions of slightly enhanced emission that rotate along the electrodes circumference. This effect is not systematically observed and when it occurs, the number and speed of the spheroids can vary with(More)

In this paper we report on two instabilities observed in dusty plasmas, at different stages of dust particle formation. Experiments are performed in a low-pressure Ar/SiH 4 radiofrequency plasma. The first instability, occuring at the transition between nanocrystal accumulation and coalescence phases, is very sensitive to operating conditions. It is shown(More)
Single stranded oligonucleotides (SSO) represent a novel therapeutic modality that opens new space to address previously undruggable targets. In spite of their proven efficacy, the development of promising SSO drug candidates has been limited by reported cases of SSO-associated hepatotoxicity. The mechanisms of SSO induced liver toxicity are poorly(More)
Ni-YSZ films are deposited by reactive magnetron sputtering from a single Ni/Zr/Y metallic target at rates as high as 4µm.h-1. Tailoring both DC pulsed power and oxygen partial pressure, a stable deposition process was obtained. Columnar morphology was observed in the as-deposited films. Annealing in air at 900°C was conducted, after which a fully(More)

Thermal stability of AlCoCrCuFeNi high entropy alloy thin films studied by in-situ XRD analysis Abstract High entropy alloys (HEAs), containing five to thirteen metallic elements, with a concentration in the range of 5 to 35 % for each element, exhibit very interesting properties (mechanical, tribological, formability, magnetism...). Their high mixing(More)

Energy exchanges due to chemical reactions between a silicon surface and a SF 6 plasma were directly measured using a heat flux microsensor. The energy flux evolution was compared with those obtained when only few reactions occur at the surface to show the part of chemical reactions. At 800 W, the measured energy flux due to chemical reactions is estimated(More)
