Large and complex construction projects lace risk trom various sources and the successlul completion of such projects depends on effective risk management. This study investigates the risk faced by Chinese firms participating in constructing AP 1000 nuclear power plants in China. AP 1000 nuclear reactors are new, Generation iii＋ reactors designed by Westinghouse and to be built first in China. The semi-structured interview approach is used to elicit information from experts involved in the AP1000 projects in China. Based on the interviews, various sources of risk are identified. in addition to general risks that megaprojects normally face, there are unique risks that arise from various sources such as technological, political, organizational, and individual personnel risks. Risk management strategies are proposed to manage general and unique risks identified in the study. The findings of this study would be helpful for Chinese companies involved in the construction of AP 1000 nuclear power plants to mitigate the risks associated with the projects.

A solvable model of lateral line of a fish based on a wave equation with additional boundary conditions on a set of isolated points is *** the framework of this model it is shown that the ratio of pressures on lateral lines on different fish flanks,as well as the cross section of sound scattering on both the lines,strongly depends on angles of incidence of incoming sound *** strong angular dependence of the pressure ratio seems to be sufficient for the fish to determine the directions from which the sound is coming.

Particle melting and substrate temperature are important in controlling deposited density and residual stress in thermal plasma deposition of refractory materials. in this paper, both the heating and cooling behaviours of tungsten particles inside a radio frequency inductively coupled plasma （iCP） and the plasma heat flux to the substrate were investigated. The distribution of the plasma-generated heat on device, powder injection probe, deposition chamber, and substrate was determined by measuring the water flow rate and the flow-in and flow-out water temperatures in the four parts. Substrate temperature was measured by a two-colour pyrometer during the iCP deposition of tungsten. Experimental results show that the heat flux to the substrate accounts for about 20% of the total plasma energy, the substrate temperature can reach as high as 2100 K, and the heat loss by radiation is significant in the plasma deposition of tungsten.

ischaemia-reperfusion injury(iRi) is the leading cause of injury seen in the liver following transplantation. iRi also causes injury following liver surgery and haemodynamic shock. The first cells within the liver to be injured by iRi are the liver sinusoidal endothelial cells(LSEC). Recent evidence suggests that LSEC coordinate and regulates the livers response to a variety of injuries. it is becoming increasingly apparent that the cyto-protective cellular process of autophagy is a key regulator of iRi. in particular LSEC autophagy may be an essential gatekeeper to the development of iRi. The recent availability of liver perfusion devices has allowed for the therapeutic targeting of autophagy to reduce iRi. in particular normothermic machine liver perfusion(NmP-L) allow the delivery of pharmacological agents to donor livers whilst maintaining physiological temperature and hepatic flow rates. in this review we summarise the current understanding of endothelial autophagy and how this may be manipulated during NmP-L to reduce liver iRi.
