... INVESTIGATION OF JOINT EFFECT OF TWO . MECHANISMS OF PROBE WAVE ANOMALOUS ATTENUATION . ... As it follows from the title of our paper, I shall speak about two mechanisms of anomalous attenuation, one of the basic effects been observed under ionospheric heating by powerful HF waves. ... The second mechanism of anomalous attenuation is multiple scattering. ... Perhaps, anomalous attenuation been observed at Arecibo will be easier explained by multiple scattering mechanism. ...

What is the VSM ? ... VRML = Virtual Reality Modeling Language. ... One of the best VRML viewers, if not the best, is Netscape Navigator with Live3D plugin. ... Warning: if you use any other viewer, spacecraft will probably look like parrots or clowns because each VRML viewer treats colors in its own unpredictable way. ... You can use these VRML models freely in any way you like, but: 1) let me know you use them; 2) if you add them to your Web page, a reference to the VSM must be there. ...
