Loaded indicator

A second piece of important information obtained by PCA is the loadings, which are denoted by PI, P2, etc. They indicate which variables influence a model and how the variables are correlated In algebraic terms the loadings indicate how the variables are combined to build the scores. Figure 9-8 shows a loading plot each point is a feature of the data set, and features that are close in the plot are correlated. 

Results of the cyclohexane oxidation tests are shown in Table 41.4. Mono-oxygenated products are cyclohexanone, cyclohexanol and cyclohexyl hydroperoxide. Cu and Cr were very active, but subsequent tests showed considerable leaching for both metals, whereas Co-Si-TUD-1 did not show ai r leaching. Tests with different Co loadings indicate that the lowest Co concentration has the best conversion and ketone selectivity. Isolated cobalt species are most efficient for the conversion of cyclohexane, as agglomeration of Co reduces...

Fig. 5. WAXD spectra for (A) BB-loaded PSA, and (B) PNA-loaded PSA. (A) BB loading is (a) 0, (b) 15, (c) 30, and (d) 45. Note that as loading increases, the spectrum shows no change for the PSA crystallinity, but crystals of BB appear, indicating that the solute and polymer are immiscible. (B) PNA loading is (a) 0, (b) 5, (c) 10, and (d) 15. Note that there are no peaks corresponding to PNA as the loading increases, however, the polymer crystallinity decreases with increased loading, indicating polymer/solute compatibility.

A survey of glazing failures due to wind load indicates that improper installation of setting blocks, gaskets or lateral shims, or poor edge bite is a significant cause of failure because of the resultant unconservative support conditions. To prevent premature glass failure, a strenuous quality control program is required. 

It prorides information about the measurement variables. The loadings indicate the amount of variation contained by each measurement variable. 

The data in Table IV and Figure 8 show that the dispersion of nickel decreases with increasing nickel loading from 90% (1 wt%) to 22% (10wt%). However, the turn over frequency of the carbonylation is independent of the Ni loading, indicating that this reaction is a structure insensitive reaction.

One of the key discoveries during the first Raman experiments with cells that allowed control of the sample environment was a demonstration of the influence of moisture on the spectra of some catalysts. For example, supported metal oxide catalysts exhibit different Raman spectra depending on the loading of the metal oxide, such as molybdenum oxide. When the Raman spectra were recorded under ambient conditions, the spectra of the catalysts with low molybdenum loadings indicated the presence of monomolybdates, as characterized by the prominent band at about 900 cm-1. In contrast, polymolybdates, indicated by Raman bands between 930 and 960 cm-1, were detected at intermediate loadings, and crystalline M0O3 nanoparticles were found in materials with high... 

Another way of considering the effect of particle bounce is shown in Fig. 7.6. A plot of collection efficiency versus substrate loading indicates efficiencies which never reach 100 percent Particle bounce can be minimized by using collection media coated with such materials as Vaseline, L and H high-vacuum greases, stopcock grease, oil, or Apiezon (Moss and Kencyer, 1986). 

The 3-to-2 photon ratio technique observes the ratio of 3 versus 2 photon annihilations of positronium (and positrons). In vacuum positronium will annihilate via 3-photon decays only. Trapped inside closed pores, both annihilation paths are possible. This change can be used to detect the onset of open porosity as shown in Figure 7.2. A change in slope (the slope is shown as a solid line) occurs at about 23% porogen load, indicative of an increased likelihood for positronium to escape from the sample.

The level of a project execution plan discussed in this book is basically a master bar chart schedule showing the required labor loading, indicating the contracting strategy and the expected rate of progress. 

The observation of a chronic urticaria in two sisters who excreted abnormal amounts of xanthurenic acid after a 10-g DL-tryptophan load indicated to Knapp et al. (K6) that constitutional genetic factors may be involved in vitamin Bg-deficiency symptoms. This was borne out by a very high xanthurenic acid level during a similar test on another family.
