Is regulation by milestones efficiency enhancing? An experimental study of environmental protection

An Experimental Study of Foundation Underpinning by Piles

Existing buildings sometimes experience excessive settlement under their design loads or face the prospect of excessive settlement in the future if a change of building use is required and increased foundation loadings will occur. Several methods of foundation enhancement are available to arrest settlements or improve the future performance of existing foundations including the method of underp...

Two Decades of Enhancing Children’s Environmental Health Protection at the U.S. Environmental Protection Agency

Introduction Children do not react like adults when exposed to environmental chemicals because their organ systems and metabolic capabilities are not fully developed. Children eat, breathe, and drink more, relative to their body mass, than adults. Their exposures to environmental chemicals differ from that of adults due to child-specific behaviors, such as hand-to-mouth and object-to-mouth acti...

Enhancing Phytoremediation Efficiency in Response to Environmental Pollution Stress

An Experimental Study of MR Dampers for Seismic Protection

In this paper, the efficacy of magnetorheological (MR) dampers for seismic response reduction is examined. To investigate the performance of the MR damper, a series of experiments was conducted in which the MR damper is used in conjunction with a recently developed clipped-optimal control strategy to control a three story test structure subjected to a one-dimensional ground excitation. The abil...
