Responsive to an operation request being sent from a requesting application to the set of directory servers and an administrative maintenance control mechanism being active, an administrative maintenance control is automatically sent to the set of directory servers. A next step includes decoding downlink data in a downlink subframe of the frame using the different technologies utilizing information in the control messages. One flows positively or negatively pressurized blood through the blood flow tubing, with the result that the pressure of the blood is communicated through the aqueous solution and the air volume in the branch connection tubing to the pressure transducer unit, with the blood being spaced from the air volume. Polymer-cement composites are also generally provided that, in one embodiment, include cement, sand, and poly, with the polymer-cement composite having a compressive strength of 8000 psi. A CPU and program memory are programmed to perform a validation function, such as a one-way hash function, on the captured sensor signal while transferring it to persistent memory device so as to derive a validation value which is also stored in persistent memory device.
