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.
Obstructed ducts, such as the ejaculatory duct, and the formation of cysts in the prostate or seminal vesicles can cause hematospermia. When ducts are blocked, nearby blood vessels can dilate and rupture. An enlarged prostate, also called benign prostatic hyperplasia, pinches the urethra and can lead to hematospermia, too. Tumors Benign polyps and malignant tumors of the prostate, testicles, epididymis, and seminal vesicles may cause hematospermia.
