Chemicals with a shorter half-life reach steady state more rapidly, leading to the faster attenuation of the impact that these physiologic events may have on blood concentration.
Furthermore, in pramipexole and MPTP treated mice, a significant attenuation of the impact of MPTP in the CPu (-27% vs -52% loss) and Nac of MPTP treated mice was seen.
The results of this multi-country investigation provide evidence of an attenuation of the mortality impact associated with heat in the majority of countries included in the analysis, with significant reductions estimated in Japan, Spain, and the USA; a nonsignificant decrease in Canada; uncertain and nonsignificant changes in Australia and South Korea; and little evidence of any change in the UK.
Finally the main outcome of this investigation is to provide information regarding the use of expanded metal tubes in the design of impact attenuation devices.
The objectives of the research project are to generate research information to enhance the understanding of impact attenuation of FPS, energy absorption, critical stresses, and failure modes, to develop a simple procedure for evaluating the performance and suitability of a FPS and to study the effects of important parameters on FPS design using finite element technique.
In the study of impact attenuation devices, rings/tubes have received a large amount of research due to their adaptability, i.e. they are low in cost and are readily available for selection in the design process.
The identification of these mechanisms extends understanding of natural attenuation of potential secondary impacts at enhanced reductive dechlorination sites, particularly for reduced Fe plumes, produced CH4, and pH perturbations.
Installing shock mats and geosynthetics in the track substructure led to the attenuation of high cyclic and impact forces, thereby mitigating ballast degradation.
As elegantly outlined by Eckhoff, the modest attenuation of LLIN and IRS impact by zoophagic, exophagic, and exophilic primary vectors simply leaves far too high a level of residual transmission for conventional drug or vaccine-based strategies to completely mop up the reservoir of parasite infection.

Simulation data indicate that the reconstructed shear moduli are independent of variations in tissue attenuation that impact the spatial distribution of radiation force in the ROE.
