Load observation

Scratch methods are useful above all in the determination of the conventional hardness number which is linked to a specified, standardized scratch width. This follows from the absence of a directly proportional relation, as one would expect, between scratch width and square root of load, observable in the case of some materials. When such materials are tested, the scratch width increases at a slower pace than does the square root of the load. Since the relation varies with load, the scratch-width variation curves for various materials may intersect, thus making it impossible to arrange them by scratch-determined hardness. The order in which they are ranked may vary according to applied load. 

Based on acetone solubility alone one would expect DC1 to behave similar to OX, however DC1 depletion of the outer layer is limited by its high solubility in the polymer itself. The generally higher loadings observed with DC1 (Table I) and the fact that the DC1 loaded beads, especially the more polar ones are often clear or contain clear regions indicate high solubility. Partition coefficients (25°C) from phosphate-buffered saline (pH = 7.4) into octanol are... 

The results of Cu loadings observed for samples prepared by ion exchange of silica with [Cu(en)2] appear to be confirmed by the recent data reported by Toupance, et al on their attempts to prepared Cu/silica solids. They reported Cu loadings < 2 wt% when the cation was the copper ethylenediamine however, they did not mention the use of a co-solvent. 

In the figure 3 we present data on single component adsorption isotherms and simulation results. Data obtained from the literature [6] are included for comparison. The increase of the loading observed on the high pressures region can be explained by capillaiy condensation in the exterior secondary pore system, in particular between the crystals. This has been observed also by other authors [S]. 

Chemical oxygen demand (COD) is another useful tie parameter that sharpens the material balance exercise, especially to link the production areas with the effluent treatment plant. The audit team can estimate the contribution of each process department in terms of total COD load in kg/day, knowing the volume of wastewater and the COD discharged by each department and cross checking it with the COD load observed at the treatment facilities.

The more rapid decreases in activity for GVAI2O3 catalysts of lower cobalt loading observed in this study is inconsistent with the results for the Co/zeolite catalysts. Although reasons for the high resistance of cobalt clusters within zeolites cannot yet be specified, the unusual chernical/electronic environments of zeolite pores and/or small metal clusters may play important roles. 

There remains the question of whether the drop in load observed at yielding arises from the purely geometrical strain softening associated with a true-stress-strain curve of the form shown in fig. 8.4(c), where there is no drop in the true stress but merely a reduction in slope of the stress train curve, or whether there is actually a maximum in the true-stress strain curve as shown in fig. 8.4(d). Experiments on polystyrene and PMMA in compression, under which the geometrical effect cannot take place, show that a drop in load is still observed. Results from extensive studies of PET under a variety of loading conditions also support the idea that a maximum in the true-stress train curve may occur in a number of polymers.

Figure 8-4 shows the packed sections of an FCCU fractionator. Table 8-1 summarizes the maximum loads observed on the fractionator. The observed pressure drops reported for sections 4, 5, and 6 are at incipient flood for the individual sections. The low pressure drop reported for the top three sections is due to the fractionator being limited by the capacity of the tower by the lower sections.

The observations were done in 2014 on one of container terminals in Poland. Observations treat handling relation wagon-yard at the container terminal. Containers were taken from the first or second rail track, then put at the free space on the storage yard in one of the 4 levels. The aim of the research was to characterize the relationships binding site to download and postpone load. Observations were including duration of operation and the distance moved both with load and without.
