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.
What causes light sensitivity (photophobia)? Light sensitivity can be caused by lots of different things. Having an eye condition or migraines and getting older are some of the more common reasons. Some people are just naturally more sensitive to light than others without there being a cause. Our information concentrates on light sensitivity caused by eye conditions, but the ideas may also help for people without any eye conditions.
