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.
Approximately 25% of urine specimens containing bacteria will have a positive protein reaction as the only positive dipstick reaction. The esterase reagent is sensitive to 15 leukocytes per hpf, but the protein reagent is sensitive to 6 leukocytes per hpf.
