Sensing conditions

The influences of spot size and antigen density on sensitivity were examined. As predicted from Ekins (1990) microspot model (but under presumed mass-sensing conditions), the signal intensity decreased upon dilution of the antigen independent of spot diameter (area) or antigen density (Figure 6.12). The comparison of sensitivities (lowest detectable... 

Today s online model applications can sense conditions that indicate what equipment is in operation or out of service, and how equipment is configured ( lined up"). "Presolve" logic, based on measured data, automatically turns equipment models on and off and configures equipment model interconnections and values correctly. Posing the... 

This is about 10 times lower than previously reported values under the same sensing conditions. ... 

The equilibrium constant A in this case is called the formation constant or stability constant, since it is measuring formation of a metal complex, and defining its thermodynamic stability. Experimentally, because we measure K values under non-ideal (in a thermodynamic sense) conditions, the term constant here is not absolutely correct, as discussed above. Remember that it is defined only under the particular experimental conditions employed in reality, although it is fairly true to say that the value varies in only a limited way across the range of conditions that we are most likely to apply. 

Feedforward Control Cascade Control Set points are given by the sensed conditions upstream of the process. Chemical process control... 

In midtrimester human foetal lung explants treatment with antisense epidermal growth factor receptor oHgonucleotide (15-90/iM) decreased both surfactant protein A mRNA and protein compared with controls with no effect in the sense condition (Klein et al. 2000). The ohgonucleotides did not affect tissue viability as measured by the release of lactate dehydrogenase. 

In more sophisticated drag deUvery systems the gel can sense conditions inside the body and t ry the rate of delivery. An example is an artificial pancreas representing a device capable of secreting insulin in response to a change in the glucose concentration. 

Pb analyte ions at pH 9, 3, 9.5 and 7, respectively. Note the concentration of diverse ions was in ppm, and given with the notations of interfered ions (x-axis). The inferred species were also first mixed with the monolithic sensors before addition of the analytes under working sensing conditions of 4 mg sensor, 20 ml volume and 25 °C.
