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.
Paroxysmal Nocturnal Hemoglobinuria Causes. The main reason behind the occurrence of PNH is the mutation in the single stem cell gene named PIG-A. The gene is located on the X-chromosome in oneâs bone marrow. The exact reasons responsible for triggering this gene mutation are not known yet.
