Induction ratio

The characterization of the nar promoter in E. coli with the intact nar operon on the chromosome was carried out. Expression of P-galactosidase was maximal when the nar promoter was induced at ODgoo =1-7 under anaerobic conditions in the presence of 1 % nitrate. At this optimal condition the induction ratio was approximately 250 and the specific P-galactosidase activity was approximately 7500 Miller units at ODgoo = 2.7 [35]. In this study, we used plasmid...

Another kind of audio-frequency bridge, which has come to the fore recently and which is very convenient to use, is the transformer-ratio-arm bridge, shown schematically in Fig. 5.10. This bridge uses inductive ratio arms to compare the unknown directly with standard components. The voltage... 

The measured inductance in the two states and the inductance ratio (Tratio) are shown in Eigure 12.19. An indnctance ratio of 2.2 was achieved at 30GHz with 1.2 being the maximum inductance value.

Null methods are used at frequencies up to 50 MHz and results are compensated for electrode edge effects. NuU method with resistive or inductive ratio arm capacitance bridge suggested for frequencies of <1 Hz to a few MHz.
