Carbon/molecule/metal molecular junctions were fabricated by metal deposition of titanium or copper on monolayers of nitroazobenzene ~NAB!, biphenyl, and nitrobiphenyl ~NBP!, and multilayers of NAB and NBP covalently bonded to an sp2 carbon substrate. The electronic behavior of Ti junctions was extremely dependent on residual gas pressure during E-beam deposition, due to the formation of a diso...

Residual gas analysis may be time consuming if the identification of all species and their quantitative contribution to mass spectrum is required. This because partial pressures residual cover several orders magnitudes fragmentation patterns are in general convoluted. Noise, offset, limited ranges analysers used UHV applications further reduce sensitivity a spectrum. In this work, authors propo...

Vanadium pentoxide poisoning has been described in men working in plants processing vanadium ore by Symanski (1939) and Sjoberg (1950), and twice (Wyers, 1946; Williams, 1952) in men exposed to the soot of fuel oil burned in boilers. It does not, however, appear to have been described before in men who work on gas turbines. Since these may become much more common in the future as sources of pow...

The scattering of fast ion beams, circulating e.g. in a synchrotron, with the residual gas can lead to desorption when the scattered ions hit the aperture limiting devices of the structure [1]. Here, the impacts of recoiled residual gas particles may be an additional source for desorption. We are thus interested in the scattering of residual gas atoms or molecules by passing fast highly charged...

OBJECTIVES To evaluate the use of specific compliance (static compliance/functional residual capacity) to adjust mean airway pressure, resulting in optimal gas exchange during high-frequency oscillatory ventilation in a surfactant-deficient newborn piglet. DESIGN Prospective controlled animal study. SETTING Laboratory. SUBJECTS Eight newborn piglets at 5 days of age. BACKGROUND High-fre...

In this study, detection and identification of common faults in industrial gas turbines is investigated. We propose a model-based robust fault detection(FD) method based on multiple models. For residual generation a bank of Local Linear Neuro-Fuzzy (LLNF) models is used. Moreover, in fault detection step, a passive approach based on adaptive threshold is employed. To achieve this purpose, the a...
