D mapping

Fig. 16 2-D map of 13C DEPT-MRI spectra recorded along the length of a trickle bed. Separate acquisitions were made for each of the (a) olefinic and (b) aliphatic regions of the spectrum. The data were acquired with the bed operating at steady state for gas and 1-octene flow rates of 32 and 1.0 ml min-1, respectively. The white, horizontal lines indicate the limits of the catalyst packing. Below each 2-D map, the 1-D 13C DEPT NMR spectrum recorded at an axial location just before the reactants reach the catalyst (just above the upper white line) is shown. The peaks at 114 and 139 ppm indicate that only unreacted 1-octene exists within the bed at this location, as expected. [Pg.304]

Assuming that a number of NMR data sets (e.g., 2-D or 3-D maps of displacement vectors resulting from an external periodic excitation) from an object are acquired, the remaining difficulty is their reconstruction into viscoelastic parameters. As written in Section 2 the basic physical equation is a partial differential equation (PDE, Eq. (3)) relating the displacement vector to the density, the attenuation, Young s modulus and Poisson s ratio of the medium. The reconstruction problem is indeed two-fold ... [Pg.222]

Figure 3.1. Anyone learning biochemistry is introduced to metabolic maps of the type shown here. These 2-D representations of major pathways are becoming increasingly misleading because as this chapter shows the majority of enzymatic transformations in the natural world do not stick to the simple rules implied by such a map. The great majority of chemical diversity made by organisms is made by enzymes that are much more multifunctional so they are less easily placed on a simple 2-D map. Figure 3.1.

Fig. 47. In silu study of a-methylstyrene hydrogenation in a fixed bed of Pd/ALO catalyst, (a) Schematic representation of the bed and the chosen axial bar. (b) A mixed spatial-spectral 2-D map which corresponds to that axial bar. (c) The distribution of the liquid phase along the axial bar obtained as an integral projection of (b) on its vertical (coordinate) axis, (d f) NMR spectra of the liquid phase at various heights along the bar obtained as horizontal cross-sections of the map in (b). The location of these cross-sections is indicated in (b,c) with horizontal lines. Each spectrum corresponds to a volume of 0.66mmx 1.3mmx 2mm. The two vertical dotted lines are drawn to show the differences in relative positions of the external peaks in the spectra.

In terms of the brain-mind paradigm and its 3-D map, the AIM model, SSRIs produce the equivalent of a stimulant effect as well as paradoxical sedation. The upward shift of the M dimension, caused by the elevation in aminergic drive, makes descent into deep sleep impossible, just as amphetamines make falling asleep at all more difficult. Because subjects spend much more time in light sleep at or near waking levels, they naturally experience more dreaming and they are more aware of it because they awaken more often. [Pg.227]

Fig. 17.2. Results of polarized Raman spectroscopic analyses on the surface of yttria-stabilized zirconia in the presence of an indentation print (a) optical micrograph of the indentation print, (b) map of transformed monoclinic fraction, (c) map of 6-axis orientation of the monoclinic phase, and (d) map of the angle of c-axis orientation of the residual tetragonal phase. In both (c) and (d), the represented angle gives the inclination of the respective axes with respect to the sampling plane... Fig. 17.2.

Space can have either a 2-D map format or a 3-D model format. The vantage point does not change (generally a bird s eye view). [Pg.154]

D mapping of a sample may be achieved with an x - y drive which transports the sample at the focal region of the spectrometer or the microscope (Fig. 3.5-10 a, b Schrader, 1990). If fiber optics is employed, the fiber head may be moved while the sample remains stationary. For each resolved sample point, a spectrum may be recorded and stored. A map showing the intensity distribution of different Raman lines illustrates the distribution of specific compounds over the surface. [Pg.150]
