Response erratic

Operation and exploitation of a heat exchanger, even in situations when the device is not operating in an unsteady mode such as rotary regenerators, should require considerations of transients and corresponding heat exchanger response. Erratic operation, startups and shutdowns, and/or requirements for optimal control of systems (in which heat exchangers represent important components) are some of the reasons why time-dependent behavior should be studied.

Due to the relative uniformity of ion formation by the RF spark (although its timing is erratic), the most widely used method of quantitation in SSMS is to assume equal sensitivity for all elements and to compare the signal for an individual element with that of the total number of ions recorded on the beam monitor. By empirically calibratii the number of ions necessary to produce a certain blackness on the plate detector, one can estimate the concentration. The signal detected must be corrected for isotopic abundance and the known mass response of the ion-sensitive plate. By this procedure to accuracies within a factor of 3 of the true value can be obtained without standards. 

In patients who have failed initial therapy (i.e., salvage), liposomal amphotericin products, itraconazole, or the echinocandin caspofungin can be used. Itraconazole has a response rate of approximately 40%.100 Oral itraconazole exhibits erratic absorption the IV formulation is suspended in cyclodextrin, which is eliminated renally, and thus IV itraconazole should be avoided in patients with a creatinine clearance of less than 30 mL/minute (0.29 mL/s m2).103 Itraconazole also has negative inotropic cardiac effects and increases the serum concentrations of medications (e.g., cyclophosphamide, etopo-side, calcineurin inhibitors, and sirolimus). 

In another bioassay (Table III), an active compound (DAD) i solated from whole dwarf spikerush (Eleocharis coloradoensis) (6,7) appeared to induce floating leaf formation in American pondweed. The response to DAD was somewhat erratic and much less pronounced than that observed for ABA at even higher concentrations than ABA. (Previous work has shown that high concentrations of ABA, e. g. 5-13 ppm, inhibit sprouting of winterbuds).

The data in Tables 4 to 13 at 25°C plot nearly as vertical lines independent of the wt % NH3 in solution except for pure ammonia. At low concentrations the curves tend to deviate because of the ionization of NH3 and water. If the amount of ammonia in solution is approximately known, these curves can be used to estimate the moles of acid gas per mole of NH3 with fairly good accuracy. At 80°C the curves tend to slant more so the amount of ammonia in solution would have to be known more accurately before an estimate of the ratio of acid gas to ammonia could be made. Also we do not recommend the use of a pH probe at 80°C as a control indicator because the response of the probe is more erratic, and precise data are difficult to obtain. The use of an indicator probe at 25°C seems more logical because the output is more stable. 

Interference occurs when compounds co-elute with the analytes and are not detected directly by a specific detector. The effect is to create negative peaks or an erratic response for the analyte. This problem can be identified by using a non-specific detector such as an ion trap MS detector, an MS in the electron impact ionization mode, or a flame ionization GC detector. 

Population PK/PD models, which in addition to the characterization of PK and PD, involve relationships between covariates (for instance, patient characteristics such as age, body weight) and PK/PD parameters, allow us to assess and to quantify potential sources of variability in exposure and response in specific target population, even under erratic and limited sampling conditions. Often implications of significant covariate effects can be evaluated by computer simulations using the population PK/PD model. 

Because of erratic responses, it was difficult to determine precisely the incapacitating dose of LSD. Unlike BZ, relatively small doses of LSD could affect performance profoundly in a few individuals, while a few others managed to perform reasonably well after higher doses. Most LSD subjects remained alert and at least partially in touch with the environment, while those who received BZ did not, making unpredictability a predictable feature of LSD responses.

With any endpoint detection system several practical considerations are important for reliable results. For example, the indicator electrode should be placed in close proximity to the flow pattern from the burette, so that a degree of anticipation is provided to avoid overrunning the endpoint. Another important factor is that the indicator electrode be as inert and nonreactive as possible to avoid contamination and erratic response from attack by the titration solution. A third and frequently overlooked consideration is the makeup of the reference electrode and, in particular, its salt bridge. For example, a salt-bridge system that contains potassium chloride can cause extremely erratic behavior of any electrochemical system if the titrant solution contains perchlorate ion (because of the precipitation of potassium perchlorate at the salt-bridge titrant-solution interface). Likewise, a potassium chloride salt bridge in a potentiometric titra-...
