Acoustic microscopy acoustic microscope (CSAM), and C-mode scanning acoustic microscope (C-SAM). More recently acoustic microscopes based around picosecond ultrasonics systems have demonstrated acoustic imaging in cells using sub-optical wavelengths working with ultrasonic frequencies into the multi-GHz. Since the vast majority of acoustic microscopes in use today are C-SAM type instruments, this discussion will be limited to these instruments. Ultrasound is broadly defined as any sound having a frequency above 20 kHz, which is approximately the highest frequency that can be detected by the human ear. However, the acoustic microscopes emit ultrasound ranging from 5 MHz to beyond 400 MHz so that micrometre
Frequencies from Planet Ten Frequencies from Planet Ten Frequencies from Planet Ten is the debut album by rock band Orange Goblin. It was released in 1997 by Rise Above Records. In 2002 it was reissued as a double CD coupled with their second album, "Time Travelling Blues" (1998). The reissue version contains two bonus tracks, both taken from their Man's Ruin EP, "Nuclear Guru". The latter bonus track is a cover of Black Sabbath's "Hand of Doom". The original Japanese press also contains these two bonus tracks. Both "Saruman's Wish" and "Lothlorian" have their basis in J. R. R. Tolkien's epic fantasy "The Lord
