In contrast to straight tunnels, the mechanisms of displacement surrounding soil induced by shield excavation small radius curved tunnels are more complex. Based on field monitoring data surface settlement and horizontal a tunnel in section Zhengzhou Metro Line 3, numerical model using three-dimensional finite element method is established evaluate factors soil. The results verify validity simu...

Abstract Tunnel face is important for shallow tunnels to avoid collapses. In this study, tunnel stability studied with soft computing techniques. A database created based on the literature which used train some broadly adopted techniques, ranging from linear regression artificial neural network. The soil dry density, cohesion, friction angle, cover depth and diameter are as input parameters. te...

OBJECTIVE To determine the frequency of metabolic syndrome and its components in patients with carpal tunnel syndrome. STUDY DESIGN Case-series. PLACE AND DURATION OF STUDY Department of Neurology, Mayo Hospital, Lahore, from January to June 2012. METHODOLOGY Seventy-five (64 females and 11 males) patients with clinically diagnosed and electrodiagnostically confirmed carpal tunnel syndrom...

Work in compressed air is a dangerous activity, whether it is carried on under water in a conventional diving suit, in self-contained breathing apparatus or in a diving bell, or in relatively dry conditions in a caisson or an underwater tunnel. Surprisingly large numbers of men have worked at one time or another in compressed air in tunnels or caissons and it is the dangers which arise to the h...

This paper describes an experimental investigation of the large unsteady and impulsive pressures which are experienced on the suction surface of both an oscillating and static hydrofoil as a result of cloud cavitation. The present experiments used piezo-electric transducers t o measure unsteady pressures at four locations along the chord of the foil and a t two locations along the walls of the ...

Aerodynamic, load, flow-visualization, and inflow measurements have been made on a 10-m, three-bladed, downwind, horizontal-axis wind turbine ( HAWT). A video camera mounted on the rotor was used to record night­ time and daytime video images of tufts attached to the low-pressure side of a constant-chord, zero-twist blade. Load measurements were made using strain gages mounted at every 10% of t...

AIM Mini incision techniques for carpal tunnel release have become increasingly popular for the treatment of carpal tunnel syndrome. The main advantages of mini incision techniques are shorter recovery and return-to-work time. However, the risk of neurovascular injury still remains worrisome. We present a novel method to release the carpal tunnel by using nasal instruments. This novel technique...
