Seawall construction is possible on a community scale. There are many examples of ad-hoc construction to protect individual properties and communities. However, ad-hoc seawalls are likely to give much less consideration to the water levels, wave heights and wave loadings during an extreme event.
Leukocyte esterase (LE) is a urine test for the presence of white blood cells and other abnormalities associated with infection.he leukocyte esterase (LE) test detects esterase, an enzyme released by white blood cells. Positive test results are clinically significant. The LE test is also used to screen for gonorrhea and for amniotic fluid infections.
Identification of leukocyts esterase activity on first-catch urine specimens has been shown to be useful in screening adolescent males for urethritis. The sensitivity of leukocyte esterase on first-voided urine is 72% to 100%, and specificity is 83% to 93% for detection of either gonorrhea or Chlamydia (8,9).
