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.
Refraction of light is what causes all the colors of light to separate as light passes through water droplets suspended in the air. This causes a rainbow to appear.Refraction of light by lenses also allows images to be formed by your eyes, cameras, microscopes, and telescopes.efraction of light is what causes all the colors of light to separate as light passes through water droplets suspended in the air.
