Reducing the cost of RuO_(2)/TiO_(2)catalysts is still one of the urgent challenges in catalytic HCl *** the present work,a Ce-doped TiO_(2)supported RuO_(2)catalyst with a low Ru loading was developed,showing a high activity in the catalytic oxidation of HCl to Cl_(2).The results on some extensive characterizations of both Ce-doped TiO_(2)carriers and their supported RuO_(2)catalysts show that the doping of Ce into TiO_(2)can effectively change the lattice parameters of TiO_(2)to improve the dispersion of the active RuO_(2)species on the carrier,which facilitates the production of surface Ru species to expose more active sites for boosting the catalytic performance even under some harsh reaction *** work provides some scientific basis and technical support for chlorine recycling.

Dear Editor,This letter presents a class of saturated sliding mode control (SMC)strategy for linear systems subject to impulsive disturbance and input saturation. To ensure the feasibility of proposed SMC under saturation, a relationship is established among attraction domain, saturation structure and control gain.

The Mentawai Forearc Sliver(MFS) is characterized by oblique deformation formed as slip partitioned between normal and parallel trench plate convergence. The surge of great earthquakes from 2004 to2012 along the adjacent Sunda trench left a large unbroken segment known as the Mentawai Seismic Gap. Here, we adopted continuous Global Navigation Satellite System(GNSS) observation data to identify the present regional crustal deformation using geodetic strain rates. The principal strain rate, dilatation rate, and maximum shear strain rate are about 0.13 microstrain/yr, 0.2 microstrain/yr, and 0.1 microstrain/yr, respectively, with the range of its uncertainties between 0.01 and 0.04 microstrain/yr. The dilatation and maximum shear strain rates reveal the spatial coverage of strike-slip duplex and backthrust tectonics along the Mentawai Forearc Sliver.

The purpose of this study was to examine the secretion of inflammatory cytokines by cultured monocytes/macrophages in patients with premature coronary artery disease (CAD). The study included 38 patients with premature CAD and 35 patients without CAD. A primary culture of CD14+ monocytes was obtained by immunomagnetic separation. The inflammatory response was induced by incubation of a cell culture with lipopolysaccharide (LPS) for 24 hours on Days 1 and 6. Basal and LPS-stimulated secretion of the cytokines, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8) and monocyte chemotactic protein-1 (MCP-1) was assessed by enzyme immunoassay on Days 2 and 7 of cultivation. The level of basal secretion of TNF-α, IL-1β, IL-6, MCP-1 was higher in patients with CAD compared to patients in the control group. The levels of re-stimulated TNF-α secretion and the levels of LPS-stimulated and re-stimulated IL-1β secretion on the second and sixth days were also higher in patients with CAD. LPS-stimulated MCP-1 secretion on the second day did not differ in patients of both groups, but re-stimulated MCP-1 secretion was higher in patients with CAD. The results of logistic regression analysis showed that the basal secretion levels of IL-1β and IL-6 were independently associated with premature CAD, along with smoking, body mass index and serum HDL-cholesterol levels.
