The data include the same three exams that were used for the primary beam exposure and two more: the supine abdomen exam, which is frequently ordered for inpatients, and the lateral spot L-spine exam, which requires the most radiation to produce an image.
40], was calculated from the intensities of the (040) reflection of [Alpha]-PP, obtained from measurements with three different directions of the primary beam [in FD, against FD, normal to FD (15, 17, 18)].
In general, all intensity maps which were obtained from measurements with the primary beam normal to FD are quite symmetrical around the middle of the cross section, whereas intensity maps derived from measurements with the primary beam either in or against FD are rather unsymmetrical [ILLUSTRATION FOR FIGURE 4 OMITTED].
It is noteworthy that in the range of the surface layers even the background curves show a marked dependence on the direction of the primary beam [ILLUSTRATION FOR FIGURE 5 OMITTED].
The need is therefore for more brilliant laboratory sources: besides the use of more powerful x-ray generators, the primary beam flux can be increased by means of last-generation optical devices such as multilayer mirrors (a.
Correction procedures are not always available for the chosen experimental setting; most commercially available software packages can deal only with a circular beam and with specimens of round shape or such that the whole primary beam is intercepted for all values of [psi] and 2[theta], conditions not always met in normal laboratory practice (e.
When a polycapillary collimator is used, the divergence of the primary beam (both axial and equatorial) is mainly determined by the diameter of the capillaries, their tapering and the type of glass employed in the fabrication.
The inevitable gas scattering, both elastic and inelastic, of a fraction of the primary beam electrons has a significant and frequently severe impact on both qualitative and quantitative Si-EDS x-ray microanalysis in the VPSEM-ESEM.

Once the user enters the values for slab thickness and secondary beam spacing, the app will calculate the maximum permissible spacing for his primary beams and props, with the associated prop loads and maximum cantilever length.
The panels and primary beams can be removed for the next pour while the props remain in place for re-shoring until the concrete has completely set.
