The long-term large hydraulic head in flood season is the main cause of suffusion failure or dam break, while the suffusion failure mechanism in this case has not been specially studied. First, a newly designed hydro-mechanical coupling suffusion apparatus was introduced. Second, two short-term...

Internal erosion is one of the most common failure modes of embankment dams or foundations, and the simplest and most effective preventive measure is to build a cutoff wall. The soil at the bottom of the cutoff wall is usually under complex stress states. The deeper the cutoff wall, the higher...

Using political mobility data for 189 leaders from China’s central state-owned enterprise (CSOEs) in 2008-2011, for the first time this paper investigates the mechanism of political turnover for leaders as quasi-government officers in CSOEs. We find that: (1) the likelihood of promotion of...

A three-dimensional numerical approach incorporating the radiation, solar load, and turbine models proposed in this paper was first verified by the experimental data of the Spanish prototype. It then was used to investigate the effects of solar radiation, turbine pressure drop, and ambient...

[fre] Depuis le début des années quatre-vingt, la zone asiatique est devenue une zone stratégique pour l'industrie et pour les investisseurs japonais. Les problèmes liés à la gestion macroéconomique durant ces dernières années (notamment à l'excès de l'investissement par...

A field experiment was carried out for three years to examine the concentrations of NH4+-N, NO3−-N and dissolved total phosphorus (TP) in leachates and cumulative leaching losses in rice fields with straw retention under different rates of fertilizer N application. With straw retention, the...

A comprehensive theoretical model is proposed for the performance evaluation of a solar chimney power plant (SCPP), and has been verified by the experimental data of the Spanish prototype. This model takes account of the effects of flow and heat losses, and the temperature lapse rates inside and...

Corporate bond spreads are affected by both credit risk and liquidity and it is difficult to disentangle the two factors empirically. In this paper we separate out the credit risk component by examining bonds that are issued by the same firm and that trade on the same day, allowing us to examine...

An electric and thermal model of the hybrid device consisting of a dye-sensitized solar cell (DSSC) and a thermoelectric generator (TEG) is studied for exploiting the solar full spectrum. Analytical expressions for the power outputs and efficiencies of the DSSC, TEG and hybrid device are...
