Don Juan explained that the nagual's blow has to be delivered on a precise spot, on the assemblage point, which varies minutely from person to person. Also, the blow has to be delivered by a nagual who sees. He assured me that it is equally useless to have the strength of a nagual ...
Laboratory experiments and field observations show that the equilibrium range of wind wave spectra presents a −4 power lawwhen it is scaled properly. This feature has been attributed to energy balance in spectral space by many researchers. In thispaper we point out that white noise on an...
The characteristics of the wind and wave fields significantly depend on the examined water body, especially on the proximity of the study site to the shoreline and its shape. In semi-enclosed areas and coastal regions with nearby shorelines and islands, they differ from those in the open ocean...

Background noise levels are measured in the NASA Ames Research Center 40- by 80-Foot Wind Tunnel following installation of a sound-absorbent lining on the test-section walls. Results show that the fan-drive noise dominated the empty test-section background noise at airspeeds below 120 knots. ...

The past two decades of lunar exploration have seen the detection of substantial quantities of water on the Moon’s surface. It has been proposed that a hydrated layer exists at depth in lunar soils, buffering a water cycle on the Moon globally. However,
