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.

Positive test results are clinically significant. The LE test is also used to screen for gonorrhea and for amniotic fluid infections.
Leukocyte esterase. When testing for urinary tract infections, the sensitivity of the urine dipstick test for leukocyte esterase has been found to be, in general, slightly higher than for the dipstick test for nitrites (48-86%), while the specificity was slightly lower (17-93%). Ketones are not normally found in urine. 2  Dipstick tests for the presence of acetoacetic acid at 5-10 mg/dL but not acetone or beta-hydroxybutyric acid. 3  A positive test is associated with uncontrolled diabetes, pregnancy without diabetes, carbohydrate-free diets and starvation.
