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.
The UA dipstick is very helpful. Leukocyte esterase has a sensitivity of 75% and. specificity of 98% for the detection of a UTI. [25] A positive nitrite test has a specificity. of 90% but a sensitivity as low as 30% for a UTI. [25] Combination of the 2 tests leads to. a more accurate detection of a UTI with sensitivity of up to 88%.
