Benthic Biota and High-Frequency Acoustic Propagation
نویسنده
چکیده
We also targeted emergent fauna for manipulation, choosing elimination over enhancement as a more practical manipulation. Treatments consisted of smoothing 4-m2 plots by hand and covering them with black plastic weighed down by rebar to smother the underlying fauna. Paired controls included smoothing and rebar, but no plastic. After about 3 d, the plastic was removed to monitor the effects of repopulation by emergent fauna re-entering from other sites. As background information for this manipulation, we also collected emergence-trap samples from the study site and five 0.1-m2 grab samples from each of four stations near the corners of the study area.

Acoustic Wave propagation through multilayer Thue-Morse structures containing two, three and four materials of Cu, Al, MgO and Pb
In this paper, the acoustic wave propagation in multilayer Thue-Morse structures has theoretically been studied. The composing layers were assumed do be Cu, Al, Mgo and Pb materials. Two, three or four different materials have been used in a typical structure. By using a perpendicular incident acoustic wave, the transmission coefficient was calculated and then by its old, the frequency gaps was...
