Clobetasol propionate cream and ointment produced HPA axis suppression when used at doses as low as 2 g per day for 1 week in patients with eczema. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent corticosteroid.
BNC Connecotrs are usually applied to frequrencies below 3GHz and voltages below 500 Volts. BNC connectors exist in 50 and 75 ohm versions, matched for use with cables of the same characteristic impedance. The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in the mating ends.
The specifications for N, BNC and TNC connectors are found in MIL-C-39012. There are special extended frequency versions of the TNC that adhere to the IEC 169-17 specification for operation to 11 GHz or 16 GHz, and the IEC 169-26 specification that operate mode-free to 18 Ghz (but with significant losses).
