Based on experiment of sawing Wulian red granite with diamond circular saw, the relations between the cutting force with machining parameters are studied. Cutting speed, feed rate and cutting depth are considered as the process parameters. The cutting force in sawing granite operation are measured and the experimental results are then analyzed using response surface methodology. From the analysis, it is seen that the cutting force Fx , Fy and Fz are reduced with the increase of cutting speed and increased with the increase of feed rate and cutting depth, and the mathematical models of the cutting force are developed. By ANOVA for the cutting force models, It is concluded that the models are significant at 95% confidence level and the significant effects are the first-order of cutting speed, feed speed, cutting depth and the quadratic of cutting depth.

Relatively low medium-term weight loss, metabolic improvement, and resolution or remission of obesity-related comorbidities and high reoperation rate were observed in our population of patients with BMI ≥ 35 kg/m2 who underwent LAGB.

Wenchuan earthquake of May 12, 2008 in Sichuan province is most destructive, the most widely spread, the most difficultly to disaster relief in recent decades in China. The earthquake relief and reconstruction work is also the fastest, to mobilize the widest range of input power in an action, creating a miracle of the world's earthquake relief and reconstruction. Those successful practices provided a valuable experience reference to other areas for fight against natural disasters and rebuild their homes. This article describes the damage of housing, roads, bridges and other engineering structures and landslides mudslides, dammed lakes and other geological hazards triggered by earthquakes; Outlines the effort of the rescue operation, including personnel search and rescue, road rehabilitation, caring for the wounded, people placement and soon; Summarizes the reconstruction strategies and policies, including with Chinese characteristics” counterpart support” reconstruction mode which means a province to help a county. In the end, the article discusses the earthquake relief and reconstruction experience and inspiration.

Developing an analysis program and simulating the radiation damping effect in the infinite foundation and inputs ground motion rationally. The static and dynamic analysis of an intake tunnel for a nuclear power plant is performed with ANSYS based on some 2-D finite element models considering of structure-foundation interaction by Time-History Analysis. Aiming at different programs of two linings in tunnel, the stress and internal force distribution of the tunnel , the wall rocks and the lining is researched and analyzed, and the diagram of stress and internal force is drawn. The regularity obtained can provide the basis for the seismic response analysis and design of tunnels.

It exists a great influence on deformation and internal force of large span bridge when temperature changes, the influence of the temperature must be considered and try to avoid in the process of construction control. Under monitoring to the construction process of Tieluoping super-large bridge on the scene, the influence law on internal force of Tieluoping Bridge is analyzed considering temperature effect, and the influence considering the sunshine temperature difference on cable tower deviation and stress is obtained, and the size of influence of main girder elevation, cable force and strain because of temperature field and distribution rule internal temperature field are clear. It provides powerful help for the smooth construction.
