A convenient method for visualizing continuous trajectories is to construct an equivalent discrete-time mapping by a periodic stroboscopic sampling of points along a trajectory. One way of accomplishing this is by the so-called Poincare map (or surface-of-section) method (see figure 4.1). In general, an N — l)-dimensional surface-of-section 5 C F is chosen, and we consider the sequence of successive in-...

With two (or more) internal coordinates, numerical approaches for the PBE using sectional methods become intractable in the context of CFD. A practical alternative is to use a finite number of samples to approximate the NDF in terms of delta functions as follows ... 

In this section, methods are described for obtaining a quantitative mathematical representation of the entire reaction-rate surface. In many cases these models will be entirely empirical, bearing no direct relationship to the underlying physical phenomena generating the data. An excellent empirical representation of the data will be obtained, however, since the data are statistically sound. In other cases, these empirical models will describe the characteristic shape of the kinetic surface and thus will provide suggestions about the nature of the reaction mechanism. For example, the empirical model may require a given reaction order or a maximum in the rate surface, each of which can eliminate broad classes of reaction mechanisms. 

In the following section, methods of assessing the thickness of stratum corneum removed per tape are summarized. 

If the antigen of interest is abundant and additional sensitivity is not required, then a two-step direct method, rather than a three-step indirect method, can be anployed. With the two-step method, the primary antibody is a biotin-labeled mouse monoclonal antibody, which is followed directly by the ABC incubation step. Because of the abundance of human immunoglobulins in tissue sections, methods for staining immunoglobulin often employ biotin-labeled mouse antihuman immunoglobulin reagents. 

The approach taken is loosely based on the input-process-output meta-model utilized to transform a problem statement into a functional process. The section Scope definition discusses the intended purpose and potential constraints of the isolation effort, followed by an overview of the Toolbox available to the practitioner (input). The section Method development scouting and scale-up reviews platform-based, highly automated approaches to selectivity scouting, development of the isolation as well as options for scaling up the chromatographic separation depending on purpose and constraints (process). The final section. Performing the task, explores a work breakdown structure approach to the preparative isolation of impurities as a unit operation in the development process (output). 

The poster text is divided into the same general IMRD sections as the journal article Introduction, Methods, Results, and Discussion. Similarly, most posters include an Acknowledgments section, some have an abbreviated References section, and all have a title and author list. Most posters do not include an abstract, in part because of space limitations and in part because an abstract already appears in the conference proceedings. Like the journal article, the IMRD structure of the poster follows an hourglass shape. The top (Introduction) and bottom (Discussion) sections have a broader focus, while the middle sections (Methods and Results) have a narrower focus. Each section of the poster can be divided into individual moves or steps that guide viewers in a conventional way through the content of each section. These moves are analyzed in the next part of the chapter. 

We saw in the previous section methods for calculating confidence intervals for the difference in the SAE rates, or the event rates themselves. We will now look at methods for calculating a confidence interval for the odds ratio. 

Industrial needs for brighter phosphors in the form of well-dispersed finer particles are ever increasing, for display with higher resolution. This became realistic after the reports of Bhargava et al. (12,13). In the authors laboratory, ZnS Mn was modified by acrylic acid (AA) to increase the photoluminescence (PL) intensity (14-18). In this section, methods and characteristic features of such nanocomposites are reproduced in detail. The mechanism of increasing PL intensity is also elucidated from various angles.

The thin-section methods of the petrologist may be used for artificial specimens which are in the form of large aggregates—specimens of such materials as refractories, bricks, and boiler scales. Instead of powdering them and using immersion methods, it is possible to grind thin sections and examine them. When it is simply a question of distinguishing between a few possible constituents of known characteristics, this is a useful method. But in unfamiliar systems the powder method is likely to be more useful for identification purposes the principal function of the thin-section method in such circumstances is to provide information on the distribution, orientation, or size of the crystals of the different constituents. 

Sections Methods for the preparation of amines are summarized in Table 22.5. 

The discussion above has addressed the assessment of a product s colour or perceived colour in basic terms. In the next two sections, methods to determine which coloured compounds are present in a product will be addressed. For the purpose of this chapter, the section on synthetic dyes will cover the analysis of the water-soluble dyes, or so-called coal tar dyes, and the section on natural pigments will cover the anthocyanin pigments, such as grape skin extracts, and the carotenoid-based materials, even if they are of synthetic origin. 

As no auxiliary constants (like d and log v, see preceding section) are used in the log v-n-d space model cross-section method it can be regarded as an improvement of the application of the viscosity in the field of graphical statistical methods. 

In the previous section methods to isolate (certain classes of) phenolic compounds were described. In general, however, these methods do not provide information on specific chemical composition. In order to characterize mixtures of phenolic compounds, a variety of separation and identification methods exist. They will be described below. 

Measurements of the Concentration of Surface Sites on High-surface Area Metal Catalysts. - In the previous section methods were discussed for determining the density of different faces at the surface of a polycrystalline powder. A related problem is the determination of the co-ordination number,...
