In the present study, we aimed to investigate apatite formation onto Ti or Zr[O.sub.2] quantitatively in SBF using a 27 MHz
QCM, which enabled measurements with high sensitivity and low noise [23,24].
In the present study, we aimed to investigate the protein adsorption onto Ti and Zr[O.sub.2] using a 27 MHz
QCM, which enabled measurements with high sensitivity and low noise [18, 19].

Revenue rose by 209% year-on-year to USD41.9m in April-June 2009, mainly driven up by the ongoing conversion of wireless PC peripherals vendors from older 27 MHz
radio frequency technology to Nordic Semiconductor's 2.4 GHz components.
The satellite has a payload consisting of 24x 36MHz FSS Kuband (12 fixed and 12 steerable beams), 6x 27 MHz
BSS Ku-band and 3x 200MHz FSS Ka-Band transponders.
At 27 MHz
, insertion loss of 0.1 dB and return loss of 25 dB.
At 5 GHz, it has a maximum insertion loss of 0.3 dB and a return loss of better than 16 dB; while at 27 MHz
, the insertion loss is 0.1 dB with a return loss of 25 dB.
