It has a radiating zone of attenuating animal impact away from a concentrator such as water, mineral licks and bedding grounds among others (Washington-Allen et al. 2004).
Results show that the proposed periodic geofoam-filled trenches can attenuate surface waves effectively, when the frequencies of surface waves are located in the attenuation zones.
The near-bank zone in the floodplain played the most important role in attenuating nitrate through denitrification with an annual denitrification rate of around 130 kg N-NO3− ha−1 y−1, representing about 40% of the nitrate input in this area.
This behaviour of ethanol is not supposed to trigger any environmental concern as ethanol is highly degradable and has been reported to be completely attenuated near the source zone in a live soil lysimeter experiment [4].
In general, the former group is likely to be attenuated in the unsaturated zone due to their ready aerobic biodegradation, albeit with rate variability across the literature, whereas the fate of the latter is far less likely to be dominated by a single mechanism and dependent upon the relative importance of the various attenuation processes within individual site — VOC scenarios.
The placed peat serves two major functions of attenuating the upwelling of dissolved solutes from the underlying tailing sediments to the rooting zone, and as fen vegetation establishment substrate.
"It has an attenuating effect.
Cells treated with AICAR showed enhanced cell migration into the scratched zone, which was attenuated if AMPK, AKT2, or ATF2 were knocked down.
Although any large changes in expression limited to narrow windows of either temporal or spatial regulation in the abscission zone were likely attenuated due to sampling that included mixed fruitlets of different abscission potentials, the changes in gene expression we observed confirm earlier reports of the involvement of two important hormone signaling pathways, ethylene and ABA [ 12, 13].
Upon specification, the proliferative capacity of VCS/trabecular myocytes is significantly attenuated while the compact myocardial zone proliferates at a significantly faster rate, creating a transmural cell cycle gradient (Mikawa et al., 1992a; Mikawa et al., 1992b; Soonpaa et al., 1996; Meilhac et al., 2003).
