In recent years, thin-walled accordion tubes under axial cyclic loading due to their appropriate energy absorption mechanism and behavioral characteristics were suggested as hysteretic metallic dampers. The effectiveness of accordion metallic damper (AMD) to protect and mitigate the response of structures under seismic loading is well established both experimentally and analytically. In this pa...

Energy absorber systems like metallic dampers for controlling the structural vibrations due to earthquake have witnessed considerable development in the past few decades. Also there are some studies on the energy absorption of thin-walled tubes due to impact load. Thin-walled tubes have a large deformation capacity and are suitable energy absorbers in the structure during an earthquake provided...

in the realistic manner, piles are similar to the slender columns that soil around them acts as a lateral support. the piles situated in the liquefiable soil layers, loss their lateral supports due to the liquefaction resulted from the seismic ground motion. in this case, pile has the potency of axial instability similar to the unsupported columns. this instability can lead to the lateral buckl...

Shin, Hye-Won, Peter Condorelli, and Steven C. George. A new and more accurate technique to characterize airway nitric oxide using different breath-hold times. J Appl Physiol 98: 1869–1877, 2005. First published December 23, 2004; doi:10.1152/japplphysiol.01002.2004.— Exhaled nitric oxide (NO) arises from both airway and alveolar regions of the lungs, which provides an opportunity to characteri...

A case of rotatory dislocation of both atlanto-axial joints is presented. A review of the literature reveals two other cases, both in children. This would appear to be the first report in an adult, who survived and made a full recovery.

in studies done on porous burner, generally burners with axial flow are considered. in this paper, porous burners with radial and axial flow have been modeled numerically and results of radial and axial porous burners with equal fuel consumptions are compared. the mechanism used in combustion phenomenon is 15 stage mechanisms which predict the pollutions production precisely. the results show a...
