A inter-group scenario simulated experiment is adopted to investigate the influence of failure attribution and leaders' affective feedback on members' angry and frustration.Subjects are divided into eight groups based on four failure attributions and two affective feedbacks.The results show that, under failure circumstance at work: (1) affective feedback from leaders positively influences the members' emotions of anger and frustration.(2) Different failure feedback will influence the frustration of members.(3) Different attributions of failure have different effects on members' anger at two levels of affective feedback from the leader.The study took both failure attributions and affective feedback into consideration and enriched the study of impact of attribution on emotions.

Dry granulation, as a new process for molten blast furnace slag treatment, is an attractive alternative to water quenching. In this study, the performance of dry granulation slag in slag cement blends was investigated. The results demonstrated that the early strength for dry granulation slag cement mortar was too low, which is less than 50% of the strength for the cement clinker. After 28 days, the compressive strength for dry granulation slag cement mortar containing 35 min-milled slag powder was higher than that for cement clinker. With a decrease in cement/slag ratio, the compressive strength for dry granulation slag cement mortar decreased, and then increased, reaching 96.4% of the compressive strength for dry granulation slag cement mortar made with cement/slag ratio of 2:1. Although the content of cement clinker decreased, there was enough Ca(OH)(2) to activate dry granulation slag particles to form compact C-S-H structure when the cement/slag ratio was 1.5:1.

Thermal energy recovery of pyrometallurgy slags is a worldwide problem that is widely concerned for decades. As chemical recovery method, molten slag cascade recovery method (MS-WHCR) is proposed in this work. As typical endothermic chemical reactions, pyrolysis, gasification, calcination and reforming reactions are applied in this method. Gasification–pyrolysis system, calcination–pyrolysis system, enhanced pyrolysis system (R-SEP) and fixed carbon gasification and sorption-enhanced pyrolysis system (CG–SEP) systems of MS-WHCR method are designed. Based on the first law of thermodynamics and second law of thermodynamics, enthalpy–exergy compass analysis method is applied to analyze the exergy efficiency, consumption of reactants and products of designed MS-WHCR method, compared with traditional water quenched (WQ) method and gravity bed waste heat recovery (GWHR) method. As calculation example, 1000kg copper slag is used in this paper. The results showed that the exergy efficiency and exergy loss of WQ method are 20.7% and −947 MJ respectively. By WQ method, energy quality of molten copper slag is discounted. Copper slag particles should be fast cooled during granulation process. Thus, lots of air is blown in to make enough heat transfer with copper slag particles, which generate some exergy loss. And exergy efficiency of GWHR method is 76.9%. Using chemical endothermic reactions, MS-WHCR method improves the exergy efficiency of molten slag waste heat recovery. There is a slight fluctuation of exergy efficiency by MS-WHCR method for four kinds of systems from 66.6 to 70.1%. Fixed carbon and combustible syngas are acquired by MS-WHCR. And enhanced pyrolysis process in proposed R-SEP and CG–SEP systems improves hydrogen contents in syngas.

AZ80, AZX801, and AZX802 alloys were prepared to investigate the ignition temperature and multi-stage oxidation behavior in air. Besides, the microstructures of alloys before and after oxidation were compared. The results reveal that AZX802 exhibits the characteristics of higher ignition temperature and best oxidation resistance compared to AZX801 and AZ80, which contributes to the increase of melting temperature of secondary phase in matrix due to the formation and increase of Al2Ca, with the addition of Ca in AZ80. In addition, the incubation periods before accelerated oxidation and the beginning of the accelerated oxidation temperatures of AZ80, AZX801, and AZX802 are different during multi-stage oxidation, which also contributes to the different onset melting temperature of the secondary phase. And the beginning of the accelerated oxidation of Mg alloys at high temperature is always accompanied by the onset melting of the low melting temperature of the secondary phase and the growth of oxide nodule on the surface.

As a new reducer, biomass was tested as an alternative to coal in copper slag pelleting process by cold pressed preparation method. As two kinds of reducer, biomass and lignite were used in this paper. Without binder addition, the compressive strength of lignite pellets remained in the range of 44 N-75 N under experimental conditions. Compared with lignite, biomass provided higher reduction ratio and higher compressive strength. Fiber structure of biomass increased surface area and strengthened adhesive force of composite pellets. Compressive strength of biomass composite pellet was much higher than lignite composite pellets and remained steady between 2093N and 2246 N with the variation of pressure and CaO addition ratio when C/O was 1.0. Using biomass as reducer, reduction mechanism of copper slag was established. The reduction experiments showed that in the reduction reaction process, metallic iron outflowed from cracks in pellet and it was in the formation of sphere under the effect of surface tension. And the 'sweating metallic iron' reduced by biomass distributed more homogeneously than by lignite. When the temperature was above 1423 K, reduction ratio of copper slag was higher than 0.9. And reduction ratio reached a peak when CaO addition ratio was 0.3. (C) 2018 Elsevier Ltd. All rights reserved.

In view of the doubly-fed wind power generator (DFIG) under grid voltage unbalance, double frequency disturbance component will cause a series of electrical and mechanical problems. A novel DFIG-DVR system is proposed to ride-through unbalance grid voltage conditions, the series coupled DVR of which always maintain the constant of stator voltage, isolating primary causes of problems for grid voltage unbalanced fault. In the process of fault operation, DFIG can still achieve the target for rotor side converter to accomplish decoupled power control and grid side converter to maintain constant on dc voltage. DFIG-DVR system model was established by MATLAB/Simulink. Comparison and analysis are conducted about whether DVR is switched under the condition of unbalanced grid voltage. The simulation results show that the proposed control scheme can realize low voltage ride-through(LVRT) operation of DFIG under the conditions of unbalanced grid voltage.

Transaction cost was an important factor in the financial market. According to the situation of the underdeveloped market, we proposed a mean-variance portfolio selection model with nonsmooth concave transaction costs. This is nonsmooth programming problem.

Finally, according to annual yields of six kinds of securities in eight years, we solved the mean-variance portfolio optimal strategy with nonsmooth concave transaction costs. The example was given to illustrate the efficiency of the algorithms, which offered a new way to solve the problems of nonsmooth programming.

Blast furnace slag obtained from water quenching is generally used for cement production. However, harmful waste, such as SO2, H2S and heavy metals, is discharged into the surrounding environment after water quenching. Dry granulation is an environmentally-friendly treatment, and the performance of dry granulation slag cement is investigated in the study. The results demonstrated that the particle size distribution and XRD pattern of dry granulation slag were similar to those of slag obtained from water quenching. The early strength of cement mortar made from dry granulation slag was very low, less than 50% of the cement clinker strength. Due to the weak reaction with the slag, the content of the CH phase was high. Next the CH phase was consumed in a reaction with dry granulation slag after 28 days. Crystalline and amorphous C-S-H were formed in the hydration of the slag cement paste system from dry granulation, and were measured by XRD and FTIR. The compressive strength data, including SEM study, indicate that dry granulation slag can accelerate the hydration of slag cement in the next stage. (C) 2016 Elsevier Ltd. All rights reserved.

Traditional processes for treating vanadium slag generate a huge volume of solid residue and a large amount of harmful gas, which cause serious environmental problems. In this study, a new process for the comprehensive utilization of vanadium slag was proposed, wherein zeolite A and a V2O5/TiO2 system were synthesized. The structural properties of the as-synthesized zeolite A and the V2O5/TiO2 system were characterized using various experimental techniques, including X-ray diffraction, X-ray fluorescence, scanning electron microscopy, and infrared spectroscopy. The results reveal that zeolite A and the V2O5/TiO2 system are successfully obtained with high purity. The results of gas adsorption measurements indicate that the prepared zeolite A exhibits high selectivity for CO2 over N2 and is a candidate material for CO2 capture from flue-gas streams.

Metallurgical slags, discharged at high temperature range, are produced as by-products in metallurgical processes. In order to reuse waste energy in molten metallurgical slags, the dry granulation and waste heat recovery technology is a popular technology, Compared to water quenching granulation. In the study, the solid particle diameter and size distributions of metallurgical slags with different viscosity and surface tension by dry granulation were investigated. The results indicated that the length of molten slag ligament in granulation for ferroalloy slag, with high viscosity, was long. And there was small change in mean diameter of solid particles with an increase in rotating speed for metallurgy slag with low viscosity and surface tension. The semi-empirical relation, based on the experimental data, can be applied to Calculate mean diameter of solid particles for different kinds of metallurgical slags. For blast furnace slag and, ferroalloy slag granulation, the main mass fraction peak was located in the range of 2.44-3.14 mm. For copper slag granulation, the main mass fraction peak moved to the range of small diameter with an increase in rotating speed. (C) 2016 Elsevier Ltd. All rights reserved.

Forest fire evolution plays an important role in the decision-making of controlling the forest fire. This paper aims to simulate the dynamics of the forest fire spread using a cellular automaton approach. Having analyzed the characteristics and evolution of forest fires, a simulation model for the forest fire evolution based on the energy accumulation and release is proposed. And, taking Australia's catastrophic forest fire in 2009 as an example, the fire's evolution closely to the reality is simulated. The results of the experiments are shown that if forest energy is released in a small scale before or during the fire, the fire would be better controlled even if it does not occur. Improving the efficiency of the fire extinguishing procedures and reducing the speed of the fire spread are also effective for controlling the forest fire.
