where Ci is the concentration of the i-th species, ueo and veo are the components of the electroosmotic velocity of the i- th species, Di is the diffusion coefficient of the i-th species chosen as Di =1.0×10–1
The result of this linear analysis is shown in Fig. 7f; as seen, the slope of the fit indicated that the more silicon was present the larger the separation was between carbon lamellae – this is more consistent with intuition. The coefficient of determination (R2) was low, approximately 0.1...
Determination of Distribution Coefficient of Nitrous Acid and Evaluation of Influential Factors Nitrous acid is inevitably present in Purex process,thus,it is desired to build a HNO2 distribution model which could be incorporated into Purex computer simulation code.In this work base titration and diazo...
In our analysis we consider the particular case of a piece wise constant diffusion coefficient of magnitude for and otherwise—see also Fig. 1. Physically, this form should be viewed as an ideal limit of a two phase system with a sharp interface. A similar limit of an infinitely sharp inter...
study of Hbond links to the existence of cluster formation is an interesting reductionism, in the sense that it brings an important problem in physical chemistry into the realm of clustering and aggregate formation, which is well known in associating liquids13,14,15,16and mixtures17,18,19,20,...
There are mainly two input parameters for calibrating the residual chlorine model in a water distribution network using EPANET 2.0, the bulk water decay constant, kb and the wall decay constant, kw. From laboratory tests on bottles, the bulk decay coefficient kb was developed. EPANET 2.0 simulati...
(b) Distribution of seasonal variation represented by Spearman's coefficient between OTUs and the first canonical principle coordinate constrained by seasonal variation (result of CAPs is shown in Supplementary Figure S7B). The OTUs strongly correlated to the first CAP axis (Spearman's correlation r...
Co has a lower partition coefficient than Ni in olivine. In the 1959 Kilauea picrites I found 250 ppm Co in olivine compared to 60 in the undifferentiated melt, so we have a partition coefficient xtl/liq of about 4 compared to 13 for Ni. While Co is recovered as a by product of Ni ...
Figure 5. (a) PVT diagram for a glassy amorphous polymer (PS), showing the decrease in thermal expansion coefficient associated with the glass transition; (b) PVT diagram for a semicrystalline polymer (PP), showing the stepwise increase in density associated with crystallization; (c) piston-oper...
Thus, for a particular pixel area, the number of absent compounds is obtained as the total rank in the image minus the local rank at that pixel area. Once this is known, the absent compounds will be identified as those presenting the lowest correlation coefficient between the pixel spectrum ...
