Isothermal and cyclic oxidation behaviour of Cr/Si co-doped NiAlDy alloys were investigated at 1200°C. The role of Cr and Si in oxidation of NiAlDy alloys was discussed by combining experimental results and first-principles calculations. Cr and Si would co-segregate at grain boundaries and promoted the transformation from θ-Al2O3 to α-Al2O3 at initial oxidation stage. The NiAlDyCr-3Si alloy yielded a mass gain of ~0.64mg/cm2 after 100h isothermal oxidation and showed much improved cyclic oxidation resistance due to the pair affinity between Si and Cr which can alleviate the deleterious effect of interfacial Cr precipitation. © 2013 Elsevier Ltd.

The attribute core of inconsistent decision table plays an important role in rough set theory (RST). However, the existing methods are difficult to distinguish between the consistent core and inconsistent core attributes. In this paper, we present a novel calculation for core attributes of inconsistent decision table by proposing two improved discernibility matrices which correctly obtain core attributes from consistent and inconsistent information, respectively. Theoretical and empirical result analyses show that the proposed approach is advantage and effective. © 2011 IEEE.

Cost control standards established by Taylor's standards setting method have single level characteristics, go against to improve the validity of enterprise cost control. The changes of human's rationality, emotion and cognition make dual cost control standards emerge. Managers not only need to establish double cost control standards but also need to make the reasonable incentive contracts to encourage workers; in order to maximize self-interest, workers select their efforts according to their own information, thus produces a dynamic game between workers and managers. Through the establishment of principal-agent model based on dual cost control standards effect, this paper analyses the effects of the differences of managers incentive contracts on the degrees of workers' effort. It can be found that there is a positive correlation between the degrees of workers' effort and incentive degrees they got, for the workers reach different cost control standards, managers should set different incentive coefficients, to achieve the humanization management of cost control. ©, 2015, Systems Engineering Society of China.

Based on the diversity of the retention mechanism, mixed-mode capillary monolithic columns have broad application prospect. In this work, a novel capillary polymer monolithic column was prepared with [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SPE) as monomer, ethylene dimethacrylate (EDMA) as crosslinking agent, azobisisobutyronitrile (AIBN) as initiator and butylalcohol/1,4-butanediol/water as ternary porogens. Under the optimized reaction conditions including the proportion of monomer and porogens, amount of initiator, reaction temperature and polymerization time, the monolithic column showed good mechanical strength up to 10 MPa, high permeability of 2.17×10-14 m2 and good repeatability. The peak area RSDs of column-to-column and batch-to-batch reproducibility were 1. 0% and 4. 6%, respectively. Finally, the capillary monolithic column was evaluated with polar and non-polar test mixtures. It showed hydrophilic interaction under high organic phase while hydrophobic interaction under low organic phase, indicating it a mixed-mode monolithic column.

Background: The invasion of colon cancer is associated with the tumor angiogenesis. Endostatin is an important anti-angiogenic agent, and the additive effect of endostatin with a chemotherapeutic agent, cyclophosphamide, on micrangium has not been established. Methods: Male BALB/c strain nude mice were injected with human colorectal carcinoma cells (HCT-116). The mice were divided into four groups (n = 15, each group) and were treated with different concentrations of endostatin (15, 10, and 5mg/kg/day), cyclophosphamide (20, 10, and 5mg/kg/day), and combination of endostatin/cyclophosphamide (15 + 20, 15 + 10, and 15 + 5mg/kg/day). The tumor inhibition rate was evaluated, followed by the quantification of messenger ribonucleic acid (mRNA) and protein expression of notch signaling components NOTCH-1, NOTCH-3, NOTCH-4, JAG-1, DLL-4, Hes-1, and Hey-1 using quantitative polymerase chain reaction (qPCR). The protein expression of NOTCH-3, JAG-1, and DLL-4 was confirmed using western blotting. Microvessel density (MVD) was evaluated to detect micrangium following the treatment. Results: The endostatin/cyclophosphamide-treated samples exhibited an additive effect on the tumor inhibition rate and the microvessel count. NOTCH-1, NOTCH-3, NOTCH-4, JAG-1, Hes-1, and Hey-1 expression levels were highly correlated and downregulated in the treated samples, whereas DLL-4 expression was upregulated that accounted for its anti-angiogenic property. Conclusions: The combination treatment of colon cancer with endostatin and a chemotherapeutic agent, cyclophosphamide proves to be an efficient therapeutic strategy to inhibit the rapid vasculature formation confirmed by the differential expression of notch signaling components. © 2016 Lv et al.
