Under niche conservatism, species maintain the parameters of their original ecological niche through time.
On the contrary, in the control group, increased sevoflurane concentration (MAC up to1.3), and nalbuphine infusion (0.09 mg/kg/h, mean value: 5.097 ± 3.33), were required in the patients, to maintain the parameters to the lower normal values until the end of the operation.
To iterate the transference function of this circuit and also to maintain the parameter control of the LM, a current amplifier has been used.
For all parameter perturbations which maintain the parameter values within the shaded area in Fig. 7, both variables are singular and locked to their threshold, and robustness is preserved.
Figure 7 (1 3) shows the 2D contours and 3D response surface plots as a function of two parameters (by maintaining the third parameter at a constant level) which are useful for visual analysis of interaction and the combined effects of every two independent variables on responses.
In this case, maintaining the PQ parameters at the desired level will require efficient implementation methods of the metering algorithms.
In order to achieve this aim, an air-cell can be designed inside the piston body by maintaining the performance parameters.
However, during on-power refueling with full length channel and high enrichment fuel, the challenge is to control the refueling ripples and maintaining the operational parameters under their design limits.
The influence of initial pH of the Cd II), Co II), Zn II) and Pb II) solutions on the sorption capacities of the sorbents was investigated by differentiating the initial pH from 2 to 6 and maintaining the other parameters and is shown in Fig. 1e, f.
Both the conventional one-factor-at-a-time (OFT) optimization, in which one of the factors is varied maintaining the other parameters fixed at constant levels, and the central composite design (CCD) optimization, in which all factors are varied simultaneously, were carried out for silk dyeing with chlorogenic acid.
