Inconsistent changes

Only 6% of the iifitial total lycopene prepared as a thin film on the surface of each vial remained after 144 hr under fluorescent light (2000 to 3000 lux) at 25°C under N2. Lycopene degradation occurred as a first-order reaction at 2.93 x 10" /min, and the concentration of aU lycopene mono-c isomers already present in the sample, 5-cis-, 9-cis-, l3-cis- and 15-d5 -, showed an inconsistent change in this period. Nevertheless, formation of lycopene di-c isomers was observed after 32 hr of light exposure and when considering relative percentage, loss of 13% of all-trani-lycopene occurred while an increase of 11% for total cis isomers was found after 144 hr. ... 

The females that received 908 or 1,264 mg/kg/day had a significant increase in platelets (averaged across all time points) compared to the controls. Inconsistent changes in erythrocyte morphology were noted in...

Retention time inconsistency (changing, increasing, decreasing), change in separation (loss of resolution). Table 2 summarizes their causes and solutions. 

The use of hydrogeochemical prospecting is often criticised because of the lack of reproducibility of sample values. It is true that background and anomalous values are inconsistent, changing with the seasons and the passage of time in line with water-level variations and the environment in general. These variations are more pronounced for levels of uranium dissolved in water than for those expressed in the dry residue. It is possible to obtain consistent and representative values by sampling from basin to basin. 

We allow multiple views for a given argument structure, reflecting the application of different queries. The views and the queried structure are kept consistent with each other in our implementation, so that a change in any one of the views/argument structure is either propagated to the rest or, in the case of an inconsistent change (due to independent unsaved edits, say), the user is alerted. 

Inconsistent changes When teams of engineers develop and maintain their component models, concurrent changes may become inconsistent when integrated into a concrete product that is based on several interdependent components. If inconsistent changes are detected in a late phase of a project, costs of fixing them may increase significantly. 

Known samples should also be run to verify the accuracy and precision of the routine methods to be used during the unit test. Poor quality will manifest itself as poor precision, measurements inconsistent with plant experience or laboratory history, and disagreement among methods. Plotting of laboratory analysis trends wiU help to determine whether calibrations are drifting with time or changing significantly. Repeated laboratory analyses will establish the confidence that can be placed in the results. 

The aforementioned inconsistencies between the paralinear model and actual observations point to the possibility that there is a different mechanism altogether. The common feature of these metals, and their distinction from cerium, is their facility for dissolving oxygen. The relationship between this process and an oxidation rate which changes from parabolic to a linear value was first established by Wallwork and Jenkins from work on the oxidation of titanium. These authors were able to determine the oxygen distribution in the metal phase by microhardness traverses across metallographic sections comparison of the results with the oxidation kinetics showed that the rate became linear when the metal surface reached oxygen... 

A frequently used test has x-rays or gamma rays passing through a structure that absorbs distinctive flaws or inconsistencies in the material so that cracks, voids, porosity, dimensional changes, and inclusions can be viewed on the resulting radiograph. 

The second and the final changes may involve more than a single polymorph. There is thus the problem of identifying each rate process with a particular chemical transformation, and many reported inconsistencies remain to be resolved. 

Now that we have a model, we must check its consistency with various experiments. Sometimes such inconsistencies result in the complete rejection of a model. More often, they indicate that we need to refine the model. In the present case, the results of careful experiments show that the collision model of reactions is not complete, because the experimental rate constant is normally smaller than predicted by collision theory. We can improve the model by realizing that the relative direction in which the molecules are moving when they collide also might matter. That is, they need to be oriented a certain way relative to each other. For example, the results of experiments of the kind described in Box 13.2 have shown that, in the gas-phase reaction of chlorine atoms with HI molecules, HI + Cl — HC1 I, the Cl atom reacts with the HI molecule only if it approaches from a favorable direction (Fig. 13.28). A dependence on direction is called the steric requirement of the reaction. It is normally taken into account by introducing an empirical factor, P, called the steric factor, and changing Eq. 17 to... 

It is seen that the profile of the combined peaks is perfectly symmetrical and displays no hint that there are two solutes present. Obviously an absorption ratio curve from a diode array detector would quickly disclose the presence of the two components, as would an appropriate changes in mobile phase composition. However, there would be a further clue for the analyst to follow that would give warning of the "duplicity" of the peak. The double peak would be very broad and be inconsistent with the change in peak width of the other solute peaks with retention time. The peak width of a solute increases regularly with retention time but, unfortunately, the relationship is not smooth. There are good reasons for this, but they... 

Basically, there may be three reasons for the inconsistency between the theoretical and experimental friction factors (1) discrepancy between the actual conditions of a given experiment and the assumptions used in deriving the theoretical value, (2) error in measurements, and (3) effects due to decreasing the characteristic scale of the problem, which leads to changing correlation between the mass and surface forces (Ho and Tai 1998).
