parts per billion (ppb) microcystin is unsafe to drink, and because the toxin is heat stable, boiling—the usual advice for water contaminated by microbes—is not helpful. In fact, because boiling reduces the vol-ume of the water, it simply concentrates the toxin. Shortly after the water advisory was issued, the effects could be

Note: When using a rebound hammer to estimate in-situ compressive strength, the reference curve(s) provided by the manufacturer must be used with some caution. The correlation between rebound number and compressive strength is very much dependent on the concrete mixture under test. Details on the derivation of reference

Using the BMI-for-Age Growth Charts

The rebound or increase in BMI that occurs after it reaches its lowest point is referred to as "adiposity" rebound (Whitaker et al., 1998; Rolland-Cachera et al., 1991; Rolland-Cachera et al., 1984). This is a normal pattern of growth that occurs in all children. Recent research has shown that the age when the "adiposity" rebound occurs may be a
