Refer to Design Step 1 for introductory information about this design example. Additional information is presented about the design assumptions, methodology, and criteria for the entire bridge, including the steel girder. Figure 3-1 Span Configuration. Figure 3-2 Superstructure Cross Section.
HYPOFLUORESCENCE Hypofluorescence may be caused by 1) blocked fluorescence, which is synonymous with negative fluorescence or transmission decrease, or 2) a vascular filling defect. Blocked fluorescence corresponds to the size, shape, and location of the blocking material seen ophthalmoscopically.
Blood volume is often reduced in pheochromocytoma,1 and hypovolemia has been implicated as a cause of the shock that occasionally complicates the preoperative or postoperative course.2 Essential hypertension, however, is not usually associated with signs of sympathoadrenal discharge or with reduced blood volume.3 , 4.
