Flower-like WO(3) particles with high specific surface area were synthesized via a template/surfactant-free way. Scanning and transmission microscopies and X-ray diffraction were applied to investigate the formation mechanism of the morphology. Gas sensing characterization showed an enhanced sensitivity (70 Hz/ppm) to dimethyl methylphosphonate (DMMP) as compared with previously reported WO(3) ...

A qualified estimate for pretreatment of the macroalgae Chaetomorpha linum for ethanol production was given, based on the experience of pretreatment of land-based biomass. C. linum was subjected to hydrothermal pretreatment (HTT), wet oxidation (WO), steam explosion (STEX), plasma-assisted pretreatment (PAP) and ball milling (BM), to determine effects of the pretreatment methods on the conversi...

Purpose Drawing on the literature victim precipitation theory, workplace ostracism (WO) and paranoia, this paper examines mediating role of WO paranoia–service performance (SP) relationship. This further postulates that team cognitive diversity (TCD) moderates paranoia–WO Design/methodology/approach Data were collected from 228 nurses a leading hospital located in an eastern province China. Hyp...

In the study, a MEMS-based benzene gas sensor is presented, consisting of a quartz substrate, a thin-film WO(3) sensing layer, an integrated Pt micro-heater, and Pt interdigitated electrodes (IDEs). When benzene is present in the atmosphere, oxidation occurs on the heated WO(3) sensing layer. This causes a change in the electrical conductivity of the WO(3) film, and hence changes the resistance...

Let D be a domain in the complex in-plane and let as: D —• R be a regular minimal surface. Let M(K) be the set of points tu 0. The components of M(K) are of three types: isolated points; simple analytic arcs terminating nowhere in D; analytic Jordan curves in D. Components of the third type are r...

INTRODUCTION The purpose of this study was to compare the torsion and bending properties of OneShape (OS; Micro Mega, Besançon, France) and WaveOne (WO; Dentsply Maillefer, Ballaigues, Switzerland) single-file systems. METHODS The torsional strength of OS size #25, 0.06 taper and WO primary size #25, 0.08 taper was measured by using a torsiometer after fixing the apical 5 mm of the instrument...

Catalytic and spectroscopic properties of alcohol dehydrogenase from horse liver, incorporated in reversed micellar media, have been studied. Two different reversed micellar systems have been used, one containing an anionic [sodium bis(2-ethylhexyl)sulfosuccinate, AOT], the other containing a cationic (cetyltrimethylammonium bromide, CTAB) surfactant. With 1-hexanol as substrate the turnover nu...

OBJECTIVE To investigate the effect of sitting posture on lung capacity and expiratory flow (LC-EF) and lumbar lordosis. DESIGN Repeated measures on 1 group of subjects in 4 postures. SETTING Laboratory. PARTICIPANTS Seventy able-bodied volunteers. INTERVENTIONS Postures were assumed randomly: normal, with full ischial support and flat lumbar support; slumped, with the pelvis positioned...
