Stability of reinforced slopes is almost always carried out using limit equilibrium methods and controlled by the shear strengths of the slope materials and the extension force of reinforcements. According to limit equilibrium methods, the stability of slopes is assessed by dividing the whole failure wedge into several vertical elements. In order to determine the safety&#10factor of the reinfor...

The authors have been designing a post-installed anchor that fixes itself into concrete material by expanding the tip in an upward direction, and conducted tensile loading tests to confirm its fundamental dynamic characteristics. test results on three types of specimens, with morphology as parameter, indicate final failure modes were all bar fractures, stable yield strength was confirmed. Addit...

Cortical trauma can lead to development of electrographic paroxysmal activities. Current views of trauma-induced epileptogenesis suggest that chronic neuronal hyperexcitability and extensive morphological reorganization of the traumatized cortex are required for the generation of electrographic seizures. However, the mechanisms responsible for the initiation of electrographic seizures shortly a...

Bi-layer lift-off metallization techniques offer significant advantages in resolution, removal, process simplicity, undercut control and yield over conventional single-layer lift-off processes. Because of its ease of application, long shelf life and lower tool cost, the polydimethylglutarimide (PMGI) bi-layer process has become an attractive method for the metallization of III-V compound semico...

In recent work @K. Srinivasan, P. E. Barclay, O. Painter, J. Chen, A. Y. Cho, and C. Gmachl, Appl. Phys. Lett. 83, 1915 ~2003!# resonant mode linewidths of 0.10 nm ~corresponding to a quality factor ;1.3310) were measured in a photonic crystal defect microcavity fabricated in an InAsP/ InGaAsP multi-quantum-well membrane. The quality of device fabrication is of critical importance in the perfor...
