While several factors determine ESP collection efficiency, ESP size is most important. Size determines treatment time, the longer a particle spends in the ESP, the greater its chance of being collected. Maximizing electric field strength will maximize ESP collection efficiency. Collection efficiency is also affected to some extent by dust resistivity, gas temperature, chemical composition (of the dust and the gas), and particle size distribution. 

In the previous examples, the feed characterizing correlations in Chapter 2 are used to determine composition of the feedstock. The results show that the feedstock is predominantly paraffinic (i.e., 61.6% paraffins. 19.9% naphthenes, and 18.5% aromatics). Paraffinic feedstocks normally yield the most gasoline with the least octane. This confirms the relatively high FCC gasoline yield and low octane observed in the test run. This is the kind of information that should be included in the report. Of course, the effects of other factors, such as catalyst and operating parameters, will also affect the yield structure and will be discussed. 

The fate of surfactants (Fig. 1.17) in wastewater treatment plants (WWTP) is determined by, among other factors, the composition of the wastewater, the operational type of the WWTP and the physicochemical properties of the surfactant molecule itself. In general, WWTPs provide a primary treatment, which is simply the removal of solid materials by mechanical means. 

Microstructures of CLs vary depending on applicable solvenf, particle sizes of primary carbon powders, ionomer cluster size, temperafure, wetting properties of carbon materials, and composition of the CL ink. These factors determine the complex interactions between Pt/carbon particles, ionomer molecules, and solvent molecules, which control the catalyst layer formation process. The choice of a dispersion medium determines whefher fhe ionomer is to be found in solubilized, colloidal, or precipitated forms. This influences fhe microsfrucfure and fhe pore size disfribution of the CL. i It is vital to understand the conditions under which the ionomer is able to penetrate into primary pores inside agglomerates. Another challenge is to characterize the structure of the ionomer phase in the secondary void spaces between agglomerates and obtain the effective proton conductivity of the layer. 

In summary, it can be stated that the stationary phase and the mobile phase (buffer) pH are the most important factors determining the generic selectivity of a CS. The organic modifier composition and the column temperature can influence the selectivity locally, i.e., when separating a specific mixture of rather similar compounds, e.g., a drug impurity profile. 

Tzeng et al studied the SCCO2 extractions with addition of 16.25% ethyl alcohol as a co-solvent to obtain scopoletin and artemisinin (1) from A. annua. A two-factor central composite experimental design was adopted to determine the optimal extraction conditions. Two-hour ethanol-modified SCCO2 extractions was more efficient than 16 h-Soxldet hexane extraction to provide pure artemisinin (1). ... 

The details concerning how these factors determine the required number (N) of specimens per composite are described in the following sections. 

Both maternal and infant factors determine the final amount of drug present in the nursing child s body at any particular time. Variations in the daily amount of milk formed within the breast (e.g., changes in blood flow to the breast) as well as alterations in breast mUk pH wUl affect the total amount of drug found in mUk. In addition, composition of the milk will be affected by the maternal diet for example, a high-carbohydrate diet will increase the content of saturated fatty acids in milk. 

Equation 28 differs formally from Equation 17 only in that the term involving the interaction with the surface is missing in Equation 28. Thus, there are two factors determining the distribution of the surfactants between the solution and the micelles. The first involves the cmc s of the two single surfactants and the second factor involves the interaction between the two surfactants in the micelle. In the ideal case, i.e. where x. 2 the surfactant composition in the micelle is related to the solution composition, at the onset of micelle formation, through... 

This chapter focuses its attention on the discussion of the most relevant questions of interfacial adhesion and its modification in particulate filled polymers. However, because of the reasons mentioned in the previous paragraph, the four factors determining the properties of particulate filled polymers will be discussed in the first section. Interactions can be divided into two groups, parti-cle/particle and matrix/filler interactions. The first is often neglected although it may determine the properties of the composite and often the only reason for surface modification is to hinder its occurrence. Similarly important, but a very contradictory question is the formation and properties of the interphase a separate section will address this question. The importance of interfacial adhesion... 

As was mentioned above, four main factors determine the properties of particulate filled polymers characteristics of the components, composition, structure and component interactions. All four are equally important and must be adjusted to achieve optimum properties and economics.

Association of kraft lignin is mainly based on internal and external factors. The composition and the functional groups within the kraft lignin structure are important internal factors in determining the thermodynamic behavior of kraft lignin. The major groups are the aromatic ring (1/C9),...
