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.
1 A tumor located in or near the pituitary gland is the most common cause of hypopituitarism. 2  Pituitary surgery or radiation is a potential cause. 3  Hypopituitarism may develop in the postpartum period (Sheehanâs syndrome) because of necrosis (tissue death) in the pituitary as it outgrows its blood supply during pregnancy.
